PART I

ITEM 1. Business

General

CONSOL Energy Inc., (CONSOL Energy or the Company) is an integrated energy company operated through two primary divisions, oil and natural gas exploration and production (E&P) and Pennsylvania (PA) Mining Operations. The E&P division is focused on Appalachian area natural gas and liquids activities, including production, gathering, processing and acquisition of natural gas properties in the Appalachian Basin. The PA Mining Operations division is focused on the extraction and preparation of coal, also in the Appalachian Basin.

CONSOL Energy was incorporated in Delaware in 1991, but its predecessors had been mining coal, primarily in the Appalachian Basin, since 1864. CONSOL Energy entered the natural gas business in the 1980s initially to increase the safety and efficiency of our coal mines by capturing methane from coal seams prior to mining, which makes the mining process safer and more efficient. Over the past ten years, CONSOL Energy's natural gas business has grown by approximately 617% to produce394.4 net Bcfe in 2016. This business has grown from coalbed methane production in Virginia into other unconventional production, including hydraulic fracturing in the Marcellus Shale and Utica Shale, in the Appalachian Basin. This growth was accelerated with the 2010 asset acquisition of the Appalachian Exploration & Production business of Dominion Resources, Inc. Subsequently, on December 5, 2013, we sold Consolidation Coal Company and certain subsidiaries, including five active coal mines in West Virginia.

Our E&P division operates, develops and explores for natural gas primarily in Appalachia (Pennsylvania, West Virginia, Ohio, Virginia and Tennessee). Currently, our primary focus is the continued development of our Marcellus Shale acreage and the delineation and development of our Utica Shale acreage. We believe that our concentrated operating area, our legacy surface acreage position, our regional operating expertise, our extensive data set from development, joint ventures, non-operated participation wells, our held by production acreage position and our ability to coordinate gas drilling with coal mining activity gives us a significant operating advantage over our competitors.

Our land holdings in the Marcellus Shale and Utica Shale plays cover large areas, provide multi-year drilling opportunities and, collectively, have sustainable lower risk growth profiles. We currently control approximately 413,000 net acres in the Marcellus Shale and approximately 683,000 net acres that have Utica Shale potential in Ohio, West Virginia, and Pennsylvania. We also have approximately 2.2 million net acres in our coalbed methane play.

Highlights of our 2016 production include the following:

• Total average production of 1,080,512 Mcfe per day, an increase of 20% over 2015;

• 88% Natural Gas, 12% Liquids; and

• 54% Marcellus, 23% Utica, 17% coalbed methane, and 6% other.

At December 31, 2016, our proved natural gas, NGL, condensate and oil reserves (collectively, "natural gas reserves") had the following characteristics:

• 6.3 Tcfe of proved reserves;

• 93.2% natural gas;

• 58.9% proved developed;

• 87.6% operated; and

• A reserve life ratio of 15.85 years (based on 2016 production).

Highlights of coal activities in 2016 include the following:

• Production of 24.6 million tons of coal;

• Coal reserve holdings of 2.4 billion tons; and

• 75% of coal sales to domestic utilities.

Additionally, we provide energy services, including coal terminal services (the Baltimore Terminal), water services and land resource management services.

6

The following map provides the location of CONSOL Energy's E&P and coal operations by region:

CONSOL Energy defines itself through its core values which are:

• Safety,

• Compliance, and

• Continuous Improvement.

These values are the foundation of CONSOL Energy's identity and are the basis for how management defines continued success. We believe CONSOL Energy's rich resource base, coupled with these core values, allows management to create value for the long-term. The electric power industry generates approximately two-thirds of its output by burning natural gas or coal, the two fuels we produce. We believe that the use of natural gas and coal will continue for many years as the principal fuel sources for electricity in the United States. Additionally, we believe that as worldwide economies grow, the demand for electricity from fossil fuels will grow as well, resulting in expansion of worldwide demand for our coal and potentially for our natural gas.

CONSOL Energy's Strategy

CONSOL Energy's strategy is to increase shareholder value through the development and growth of its existing natural gas assets, selective acquisition of natural gas and natural gas liquid acreage leases within its footprint, and through the participation in global coal markets. Ultimately, we intend to separate our E&P division and our PA Mining Operations division and to focus on the growth of our E&P division. We also will continue to focus on monetization of assets to accelerate value creation and to minimize the shortfall between operating cash flows and our growth capital requirements.

We expect natural gas to become a more significant contributor to the domestic electric generation mix, as well as fueling industrial growth in the U.S. economy. With the recent growth of natural gas exports to Mexico and Canada and the United States becoming a net exporter of natural gas in 2016, we expect new markets to open up in the coming years. We feel that our significant increases in natural gas production, our reductions in drilling and operating costs and our vast acreage position will allow CONSOL Energy to take advantage of these markets.

7

CONSOL Energy’s coal assets align with the PA Mining Operations division's long-term strategic objectives. The production, which include the Bailey, Enlow Fork, and Harvey mines, can be sold domestically or abroad, as either thermal coal or high volatile metallurgical coal. These low-cost mines, with five longwalls, produce a high-Btu Pittsburgh-seam coal that is lower in sulfur than many Northern Appalachian coals.

These mines, along with our 100%-owned Baltimore Terminal, will continue to allow CONSOL Energy to participate in the world’s thermal and metallurgical coal markets. The ability to serve both domestic and international markets with premium thermal and metallurgical coal provides tremendous optionality.

CONSOL Energy's E&P Capital Expenditure Budget

In 2017, the E&P division expects capital expenditures of approximately $555 million. The E&P division capital expenditures are comprised of the following: $465 million for drilling and completion activity; $40 million for midstream, including capital contributions to CONE Midstream Partners, LP; and $50 million for other activities related to land, permitting, and business development.

DETAIL E&P OPERATIONS

Our E&P operations are located throughout Appalachia and include the following plays:

Marcellus Shale

We have the rights to extract natural gas in Pennsylvania, West Virginia, and Ohio from approximately 413,000 net Marcellus Shale acres at December 31, 2016.

The Upper Devonian Shale formation, which includes both the Burkett Shale and Rhinestreet Shale, lies above the Marcellus Shale formation in southwestern Pennsylvania and northern West Virginia. The company holds a large number of acres that have Upper Devonian potential; these acres have not been disclosed separately as they coincide with our Marcellus acreage.

In December 2016, CONSOL Energy terminated the 50-50 Joint Venture that was formed in 2011, with Noble Energy, Inc., for the exploration, development, and operation of primarily Marcellus Shale properties in Pennsylvania and West Virginia. As a result of the termination, each party now owns and operates a 100% interest in its properties and wells in two separate operating areas; and each party will now have independent control and flexibility with respect to the scope and timing of future development over its operating area.

We also hold a 50% interest in an entity that constructs and operates the gathering system for most of our Marcellus shale production. As of September 30, 2011, we contributed our existing Marcellus Shale gathering assets to this company. In September of 2014, the majority of these assets were contributed to CONE Midstream Partners LP. See "Midstream Gas Services" for a more detailed explanation.

Utica Shale

We have the rights to extract natural gas in Pennsylvania, West Virginia, and Ohio from approximately 683,000 net Utica Shale acres at December 31, 2016. Approximately 305,000 Utica acres coincide with Marcellus Shale acreage in Pennsylvania, West Virginia, and Ohio.

Coalbed Methane (CBM)

We have the rights to extract CBM in Virginia from approximately 268,000 net CBM acres, which cover a portion of our coal reserves in Central Appalachia. We produce CBM natural gas primarily from the Pocahontas #3 seam.

We also have the rights to extract CBM in West Virginia, southwestern Pennsylvania, and Ohio from approximately 912,000 net CBM acres. In central Pennsylvania we have the right to extract CBM from approximately 260,000 net CBM acres. In addition, we control approximately 584,000 net CBM acres in Illinois, Kentucky, Indiana, and Tennessee. We also have the right to extract CBM on approximately139,000 net acres in the San Juan Basin in New Mexico. We have no plans to drill CBM wells in these areas in 2017.

8

Other Gas

Shallow Oil and Gas

We have the rights to extract natural gas from shallow oil and gas positions in Illinois, Indiana, Kentucky, Pennsylvania, West Virginia, Virginia and New York from approximately 766,000 net acres at December 31, 2016. The majority of our shallow oil and gas leasehold position is held by production and all of it is extensively overlain by existing third-party gas gathering and transmission infrastructure.

Chattanooga

We have the rights to extract natural gas in Tennessee from approximately 95,000 net Chattanooga Shale acres at December 31, 2016.

Huron

We have approximately 503,000 net acres of Huron Shale potential in Kentucky, West Virginia, and Virginia; a portion of this acreage has tight sands potential.

_________

(1) Net acres include acreage attributable to our working interests in the properties. Additional adjustments (either increases or decreases) may be required as we further develop title to and further confirm our rights with respect to our various properties in anticipation of development. We believe that our assumptions and methodology in this regard are reasonable. See Risk Factors in Section 1A of this Form 10-K.

(2) Acreage amounts are only included under the target strata CONSOL Energy expects to produce with the exception of certain CBM acres governed by separate leases, although the reported acres may include rights to multiple gas seams (e.g. we have rights to Marcellus segment that are disclosed under the Utica segment and we have rights to Utica segment that are disclosed under the Marcellus segment). We have reviewed our drilling plans, our acreage rights and used our best judgment to reflect the acres in the strata we expect to primarily produce. As more information is obtained or circumstances change, the acreage classification may change.

Producing Wells and Acreage

Most of our development wells and proved acreage are located in Virginia, West Virginia and Pennsylvania. Some leases are beyond their primary term, but these leases are extended in accordance with their terms as long as certain drilling commitments or other term commitments are satisfied.

The following table sets forth, at December 31, 2016, the number of producing wells, developed acreage and undeveloped acreage:

	Gross	Net(1)
Producing Gas Wells (including gob wells)	17,314	12,846
Producing Oil Wells	189	30
Net Acreage Position:
Proved Developed Acreage	549,816	541,282
Proved Undeveloped Acreage	34,467	30,038
Unproved Acreage	4,804,804	3,745,533
Total Acreage	5,389,087	4,316,853

(1) Net acres include acreage attributable to our working interests in the properties. Additional adjustments (either increases or decreases) may be required as we further develop title to and further confirm our rights with respect to our various properties in anticipation of development. We believe that our assumptions and methodology in this regard are reasonable. See Risk Factors in Section 1A of this Form 10-K.

The following table represents the terms under which we hold these acres:    

	Net Unproved Acres	Net Proved Undeveloped Acres
Held by production/fee	3,644,799	13,967
Expiration within 2 years	68,084	9,347
Expiration beyond 2 years	32,650	6,724
Total Acreage	3,745,533	30,038

The leases reflected above as Net Unproved Acres with expiration dates are included in our current drill plan or active land program. Leases with expiration dates within two years represent approximately 2% of our total acres in the above categories and leases with expiration dates beyond two years represent approximately 1% of our total acres in the above categories. In each case, we deemed this acreage to not be material to our overall acreage position. Additionally, based on our current drill plans and lease management we do not anticipate any material impact to our consolidated financial statements from the expiration of such leases.

Development Wells (Net)

During the years ended December 31, 2016, 2015 and 2014, we drilled 36.0, 132.8 and 180.3 net development wells, respectively. Gob wells and wells drilled by operators other than our primary joint venture partners at that time, Noble Energy and Hess Corporation, are excluded from net development wells. In 2016, there were 68 gross development wells drilled but uncompleted. There were no dry development wells in 2016, 2015, or 2014. As of December 31, 2016, there are 3.0 gross completed developmental wells ready to be turned in-line. The following table illustrates the net wells drilled by well classification type:

(1) We calculate our present value at 10% (PV-10) in accordance with the following table. Management believes that the presentation of the non-Generally Accepted Accounting Principles (GAAP) financial measure of PV-10 provides useful information to investors because it is widely used by professional analysts and sophisticated investors in evaluating oil and gas companies. Because many factors that are unique to each individual company impact the amount of future income taxes estimated to be paid, the use of a pre-tax measure is valuable when comparing companies based on reserves. PV-10 is not a measure of the financial or operating performance under GAAP. PV-10 should not be considered as an alternative to the

11

standardized measure as defined under GAAP. We have included a reconciliation of the most directly comparable GAAP measure-after-tax discounted future net cash flows.

*Oil, NGLs, and Condensate are converted to Mcfe at the rate of one barrel equals six Mcf based upon the approximate relative energy content of oil and natural gas.

CONSOL Energy expects 2017 annual gas production to grow to approximately 415 Bcfe and increase to approximately 485 Bcfe in 2018.

Average Sales Price and Average Lifting Cost

The following table sets forth the total average sales price and the total average lifting cost for all of our natural gas and liquids production for the periods indicated, including intersegment transactions. Total lifting cost is the cost of raising gas to the gathering system and does not include depreciation, depletion or amortization. See Part II Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations in this Form 10-K for a breakdown by segment.

Average Lifting Costs excluding ad valorem and severance taxes (per Mcfe)	$	0.24	$	0.37	$	0.59

*Oil, NGLs, and Condensate are converted to Mcfe at the rate of one barrel equals six Mcf based upon the approximate relative energy content of oil and natural gas.

Sales of NGLs, condensates, and oil enhance our reported natural gas equivalent sales price. Across all volumes, when excluding the impact of hedging, sales of liquids added $0.09 per Mcfe, $0.05 per Mcfe, and $0.25 per Mcfe for 2016, 2015, and 2014, respectively, to average gas sales prices. CONSOL Energy expects to continue to realize a liquids uplift benefit as additional wells are brought online in the liquid-rich areas of the Marcellus and Utica shales. We continue to sell the majority of our NGLs through the large midstream companies that process our natural gas. This approach allows us to take advantage of the processors’ transportation efficiencies and diversified markets. CONSOL Energy’s processing contracts provide for the ability to take our NGLs “in kind” and market them directly if desired. The processed purity products are ultimately sold to industrial, commercial, and petrochemical markets.

We enter into physical natural gas sales transactions with various counterparties for terms varying in length. Reserves and production estimates are believed to be sufficient to satisfy these obligations. In the past, we have delivered quantities required under these contracts. We also enter into various natural gas swap transactions. These gas swap transactions exist parallel to the underlying physical transactions and represented approximately 264.9 Bcf of our produced gas sales volumes for the year ended December 31, 2016 at an average price of $3.04 per Mcf. The notional volumes associated with these gas swaps represented approximately 173.1 Bcf of our produced gas sales volumes for the year ended December 31, 2015 at an average price of $3.68 per Mcf. As of January 17, 2017, we expect these transactions will represent approximately 311.3 Bcf of our estimated 2017 production at an average price of $2.61 per Mcf, 220.6 Bcf of our estimated 2018 production at an average price of $2.75 per Mcf, 161.7 Bcf of our estimated 2019 production at an average price of $2.76 per Mcf, approximately 85 Bcf of our estimated 2020 production at an average price of $2.91 per Mcf, and approximately 6.8 Bcf of our estimated 2021 production at an average price of $3.08 per Mcf.

The hedging strategy and information regarding derivative instruments used are outlined in Part II, Item 7A Qualitative and Quantitative Disclosures About Market Risk and in Note 21 - Derivative Instruments in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K.

Midstream Gas Services

CONSOL Energy has traditionally designed, built and operated natural gas gathering systems to move gas from the wellhead to interstate pipelines or other local sales points. In addition, CONSOL Energy has acquired extensive gathering assets. CONSOL Energy now owns or operates approximately 5,000 miles of natural gas gathering pipelines as well as 250,000 horsepower of compression, of which, approximately 75% is wholly owned with the balance being leased. Along with this compression capacity, CONSOL Energy owns and operates a number of natural gas processing facilities. This infrastructure is capable of delivering approximately 750 billion cubic feet per year of pipeline quality gas.

CONSOL Energy owns 50% of CONE Gathering LLC ("CONE" or "CONE Gathering") along with Noble Energy owning the other 50% interest. CONE Gathering develops, operates and owns substantially all of Noble Energy's and CONSOL Energy's Marcellus Shale gathering systems. CONSOL Energy operates this equity affiliate. We believe that the network of right-of-ways, vast surface holdings and experience in building and operating gathering systems in the Appalachian basin will give CONE Gathering an advantage in building the midstream assets required to develop our Marcellus Shale position. On September 30, 2014, CONE Midstream Partners LP (the Partnership) closed its initial public offering. See Note 25 - Related Party Transactions in the Notes to Audited Consolidated Financial Statements in Item 8 of this Form 10-K for more information.

13

In the Utica Shale, we and our joint venture partner, Hess, primarily contract with third-parties for gathering services.

CONSOL Energy has developed a diversified portfolio of firm transportation capacity options to support its production growth plan. CONSOL Energy plans to selectively acquire as needed firm capacity while minimizing transportation costs and long-term financial obligations and, in the near term if appropriate, plans to optimize and/or release firm transportation to others. CONSOL Energy also benefits from the strategic location of our primary production areas in Southwest Pennsylvania, Northern West Virginia, and Eastern Ohio. These areas are currently served by a large concentration of major pipelines that provide us with the capacity to move our production to the major gas markets, and it is expected that recently-approved pipeline projects will increase the take-away capacity from our region. In addition to firm transportation capacity, CONSOL Energy has developed a processing portfolio to support the projected volumes from its wet production areas and has operational and contractual flexibility to potentially convert a portion of currently processed wet gas volumes to be marketed as dry gas volumes.

CONSOL Energy has the advantage of having gas production from CBM, which can be lower Btu than pipeline specification, as well as higher Btu Marcellus and Utica shale production. These types of gas can be complementary by reducing and in some cases eliminating the need for the costly processing of CBM. In addition, our lower Btu CBM and dry Marcellus and Utica production offer an opportunity to blend ethane back into the gas stream when pricing or capacity in ethane markets dictate. In developing a diversified approach to managing ethane, CONSOL Energy has entered into ethane supply agreements and is also discussing future outlet opportunities with ethane customers and midstream companies. These different gas types allow us more flexibility in bringing Marcellus and Utica shale wells on-line at qualities that meet interstate pipeline specifications.

Natural Gas Competition

The United States natural gas industry is highly competitive. CONSOL Energy competes with other large producers, as well as a myriad of smaller producers and marketers. CONSOL Energy also competes for pipeline and other services to deliver its products to customers. According to data from the Natural Gas Supply Association and the Energy Information Agency (EIA), the five largest U.S. producers of natural gas produced about 16% of dry natural gas production during the first nine months of 2016. The EIA reported 554,201 producing natural gas wells in the United States at December 31, 2015 (the latest year for which government statistics are available), which is approximately two percent lower than 2014.

CONSOL Energy expects natural gas to be a significant contributor to the domestic electric generation mix in the long-term, as well as to fuel industrial growth in the U.S. economy. According to the EIA, based on preliminary results, natural gas represented 34% of U.S. electricity generation during 2016 compared with 33% in 2015. With the recent growth of natural gas exports to Mexico and Canada and increased liquefied natural gas exports, the U.S. became a net exporter of gas in 2016. CONSOL expects the high level of U.S. gas exports to continue in the future. In addition, there is potential for natural gas to become a significant contributor to the transportation market. Our increasing gas production will allow CONSOL Energy to participate in these growing markets.

CONSOL Energy's gas operations are primarily located in the eastern United States. The gas market is highly fragmented and not dominated by any single producer. We believe that competition within our market is based primarily on natural gas commodity trading fundamentals and pipeline transportation availability to the various markets.

Continued demand for CONSOL Energy's natural gas and the prices that CONSOL Energy obtains are affected by natural gas use in the production of electricity, pipeline capacity, U.S. manufacturing and the overall strength of the economy, environmental and government regulation, technological developments, the availability and price of competing alternative fuel supplies, and national and regional supply/demand dynamics.

DETAIL COAL OPERATIONS

Coal Reserves

At December 31, 2016, CONSOL Energy had an estimated 2.4 billion tons of proven and probable coal reserves. Reserves are the portion of the proven and probable tonnage that meet CONSOL Energy's economic criteria regarding mining height, preparation plant recovery, depth of overburden and stripping ratio. Generally, these reserves would be commercially mineable at year-end price and cost levels.

Spacing of points of observation for confidence levels in reserve calculations is based on guidelines in U.S. Geological Survey Circular 891 (Coal Resource Classification System of the U.S. Geological Survey). Our estimates for proved reserves have the highest degree of geologic assurance. Estimates for proved reserves are based on points of observation that are equal to or less than 0.5 miles apart. Estimates for probable reserves have a moderate degree of geologic assurance and are computed from points of observation that are between 0.5 to 1.5 miles apart.

An exception is made concerning spacing of observation points with respect to our Pittsburgh coal seam reserves. Because of the well-known continuity of this seam, spacing requirements are 3,000 feet or less for proved reserves and between 3,000 and 8,000 feet for probable reserves.

CONSOL Energy's estimates of proven and probable coal reserves do not rely on isolated points of observation. Small pods of reserves based on a single observation point are not considered; continuity between observation points over a large area is necessary for proved or probable reserves.

CONSOL Energy's proven and probable coal reserves fall within the range of commercially marketed coals in the United States. The marketability of coal depends on its value-in-use for a particular application, and this is affected by coal quality, such as sulfur content, ash and heating value. Modern power plant boiler design aspects can compensate for coal quality differences that occur. Therefore, any of CONSOL Energy's coals can be marketed for the electric power generation industry. Additionally, the growth in worldwide demand for metallurgical coal allows some of our proven and probable coal reserves, currently classified as thermal coals, that possess certain qualities to be sold as metallurgical coal. The addition of this cross-over market adds additional assurance to CONSOL Energy that all of its proven and probable coal reserves are commercially marketable.   

CONSOL Energy assigns coal reserves to our mining complex. The amount of coal we assign to the mining complex generally is sufficient to support mining through the duration of our current mining permit. Under federal law, we must renew our mining permits every five years. All assigned reserves have their required permits or governmental approvals, or there is a high probability that these approvals will be secured.

In addition, our mining complex may have access to additional reserves that have not yet been assigned. We refer to these reserves as accessible. Accessible reserves are proven and probable coal reserves that can be accessed by an existing mining complex, utilizing the existing infrastructure of the complex to mine and to process the coal in this area. Mining an accessible reserve does not require additional capital spending beyond that required to extend or to continue the normal progression of the mine, such as the sinking of airshafts or the construction of portal facilities.

Some reserves may be accessible by more than one mine because of the proximity of many of our mines to one another. In the table below, the accessible reserves indicated for a mine are based on our review of current mining plans and reflect our best judgment as to which mine is most likely to utilize the reserve.

Assigned and unassigned coal reserves are proven and probable coal reserves which are either owned or leased. The leases have terms extending up to 30 years and generally provide for renewal through the anticipated life of the associated mine. These renewals are exercisable by the payment of minimum royalties. Under current mining plans, assigned reserves reported will be mined out within the period of existing leases or within the time period of probable lease renewal periods.

_____________

(1) The heat values shown for Assigned Operating reserves are based on the 2016 actual quality and five-year forecasted quality for each mine/reserve, assuming that the coal is washed to an extent consistent with normal full-capacity operation of the complex's preparation plant. Actual quality is based on laboratory analysis of samples collected from coal shipments delivered in 2016. Forecasted quality is derived from exploration sample analysis results, which have been adjusted to account for anticipated moisture and for the effects of mining and coal preparation. The heat values shown for Accessible Reserves are based on as received, dry values obtained from drill hole analyses, adjusted for moisture, and prorated by the associated Assigned Operating product values to account for similar mining and processing methods.

(2) Recoverable reserves are calculated based on the area in which mineable coal exists, coal seam thickness, and average density determined by laboratory testing of drill core samples. This calculation is adjusted to account for coal that will not be recovered during mining and for losses that occur if the coal is processed after mining. Reserves tons are reported on an as-received basis, based on the anticipated product moisture. Reserves are reported only for those coal seams that are controlled by ownership or leases.

The following table sets forth our unassigned proven and probable coal reserves by region:

_______________

(1) The heat value (gross calorific values) estimates for Northern Appalachian and Central Appalachian Unassigned coal reserves include adjustments for moisture that may be added during mining or processing as well as for dilution by rock lying above or below the coal seam. The heat value estimates for the Illinois Basin Unassigned reserves are based primarily on exploration drill core data that may not include adjustments for moisture added during mining or processing, or for dilution by rock lying above or below the coal seam.

(2) Recoverable reserves are calculated based on the area in which mineable coal exists, coal seam thickness, and average density determined by laboratory testing of drill core samples. This calculation is adjusted to account for coal that will not be recovered during mining and for losses that occur if the coal is processed after mining. Reserve calculations do not include adjustment for moisture that may be added during mining or processing, nor do the calculations include adjustments for dilution from rock lying above or below the coal seam. Reserves are reported only for those coal seams that are controlled by ownership or leases.

(3) 140.8 Million tons of the Northern Appalachia leased tons are controlled by Consolidation Coal Company, a former subsidiary of CONSOL Energy that was sold in December 2013. As of filing these tons are still controlled by Consolidation Coal Company but are shown in CONSOL Energy's reserves due to a binding agreement that these tons will be released to CONSOL Energy following the change in name of the Lease Holder.

(1) 143.3 Million tons for the Mason Dixon Project are controlled by Consolidation Coal Company, a former subsidiary of CONSOL Energy that was sold in December 2013. As of this filing, these tons are still controlled by Consolidation Coal Company but are shown in CONSOL Energy's reserves due to a binding agreement that these tons will be released to CONSOL Energy upon consent of the lessor.

Title to coal properties that we lease or purchase and the boundaries of these properties are verified by law firms retained by us at the time we lease or acquire the properties. Consistent with industry practice, abstracts and title reports are reviewed and updated approximately five years prior to planned development or mining of the property. If defects in title or boundaries of undeveloped reserves are discovered in the future, control of and the right to mine reserves could be adversely affected.

The following table sets forth, with respect to properties that we lease to other coal operators, the total royalty tonnage, acreage leased and the amount of income (net of related expenses) we received from royalty payments for the years ended December 31, 2016, 2015 and 2014.

	Total	Total	Total

Production

In the year ended December 31, 2016, 100% of CONSOL Energy's production came from underground mines equipped with longwall mining systems. CONSOL Energy employs longwall mining systems in our underground mines where the geology is favorable and reserves are sufficient. Underground longwall systems are highly mechanized, capital intensive operations. Mines using longwall systems have a low variable cost structure compared with other types of mines and can achieve high productivity levels compared with those of other underground mining methods. Because CONSOL Energy has substantial reserves readily suitable to these operations, CONSOL Energy believes that these longwall mines can increase capacity at a low incremental cost.

The following table shows the production from continuing operations, in millions of tons, for CONSOL Energy's mines for the years ended December 31, 2016, 2015 and 2014, the location of each mine, the type of mine, the type of equipment used at each mine, method of transportation and the year each mine was established or acquired by us.

We sell coal produced by our mines and additional coal that is purchased by us for resale from other producers. We maintain United States sales offices in Philadelphia and Pittsburgh. In addition, we sell coal through agents and to brokers and unaffiliated trading companies.

Approximately 75% of our 2016 coal sales were made to U. S. electric generators, 22% of our 2016 coal sales were priced on export markets and 3% of our coal sales were made to other domestic customers. We had sales to over 35 customers from our 2016 coal operations. During 2016, two customers each comprised over 10% of our coal sales, and the top four coal customers accounted for over 40% of our coal sales.

Coal Contracts

We sell coal to an established customer base through opportunities as a result of strong business relationships, or through a formalized bidding process. Contract volumes range from a single shipment to multi-year agreements for millions of tons of coal. The average contract term is between one to three years. As a normal course of business, efforts are made to renew or extend contracts scheduled to expire. Although there are no guarantees, we generally have been successful in renewing or extending contracts in the past. For the year ended December 31, 2016, over 65% of all the coal we produced was sold under contracts with terms of one year or more.

CONSOL Energy expects total consolidated PA Mining Operations annual sales to be approximately 26.0 million tons for both 2017 and 2018.

Coal pricing for contracts with terms of one year or less are generally fixed. Coal pricing for multiple-year agreements generally provide the opportunity to periodically adjust the contract prices through pricing mechanisms consisting of one or more of the following:

• Fixed price contracts with pre-established prices;

• Periodically negotiated prices that reflect market conditions at the time;

• Price restricted to an agreed-upon percentage increase or decrease;

• Base-price-plus-escalation methods which allow for periodic price adjustments based on inflation indices, or other negotiated indices; or

• Netback pricing.

The volume of coal to be delivered is specified in each of our coal contracts. Although the volume to be delivered under the coal contracts is stipulated, the parties may vary the timing of the deliveries within specified limits.

Coal contracts typically contain force majeure provisions allowing for the suspension of performance by either party for the duration of specified events. Force majeure events include, but are not limited to, unexpected significant geological conditions or natural disasters. Depending on the language of the contract, some contracts may terminate upon continuance of an event of force majeure that extends for a period greater than three to twelve months.

Distribution

Coal is transported from CONSOL Energy's mining operations to customers by railroad cars, trucks or a combination of these means of transportation. Most customers negotiate their own transportation rates and we employ transportation specialists who negotiate freight and equipment agreements with various transportation suppliers, including railroads, barge lines, terminal operators, ocean vessel brokers and trucking companies for certain customers.

Coal Competition

Both the domestic and international coal industries are highly competitive, with numerous producers selling into all markets that use coal. CONSOL Energy competes against several other large producers and numerous small producers in the United States and overseas. Demand for our coal by our principal customers is affected by many factors including:

• the price of competing coal and alternative fuel supplies, including nuclear, natural gas, oil and

renewable energy sources, such as hydroelectric power, wind or solar;

• environmental and government regulation;

• coal quality;

• transportation costs from the mine to the customer;

20

• the reliability of fuel supply;

• worldwide demand for steel;

• natural disasters/weather; and

• political changes in international governments.

Continued demand for CONSOL Energy's coal and the prices that CONSOL Energy obtains are affected by demand for electricity, technological developments, environmental and governmental regulation, and the availability and price of competing coal and alternative fuel supplies. We sell coal to foreign electricity generators which are significantly affected by international demand and competition.

Other Operations

CONSOL Energy provides other services both to our own operations and to others. These include land services, coal terminal services and water services.

Non-Core Mineral Assets and Surface Properties

CONSOL Energy owns significant gas and coal assets that are not in our short or medium term development plans. We continually explore the monetization of these non-core assets by means of sale, lease, contribution to joint ventures, or a combination of the foregoing in order to bring the value of these assets forward for the benefit of our shareholders. We also control a significant amount of surface acreage. This surface acreage is valuable to us in the development of the gathering system for our Marcellus Shale and Utica Shale production. We also derive value from this surface control by granting rights of way or development rights to third-parties when we are able to derive appropriate value for our shareholders.

Terminal Services

In 2016, approximately 8.1 million tons of coal were shipped through CONSOL Energy's subsidiary, CNX Marine Terminals Inc.'s, exporting terminal in the Port of Baltimore. Approximately 63% of the tonnage shipped was produced by CONSOL Energy's PA Mining Operations. The terminal can either store coal or load coal directly into vessels from rail cars. It is also one of the few terminals in the United States served by two railroads, Norfolk Southern Corporation and CSX Transportation Inc.

Water Division

CNX Water Assets LLC, doing business as CONVEY Water Systems LLC, is a wholly-owned subsidiary of CONSOL Energy and supplies turnkey solutions for water sourcing, delivery and disposal for our E&P operations, supplies solutions for water sourcing, delivery and disposal for third-parties and also provides supplemental water sourcing and marketing efforts on behalf of CNXC. In coordination with our midstream operations, CONVEY Water Systems works to develop solutions that coincide with our midstream operations to offer gas gathering and water delivery solutions in one package to third-parties.

Employee and Labor Relations

At December 31, 2016, CONSOL Energy had 2,307 employees. There were no employees represented by the United Mine Workers of America (UMWA) at December 31, 2016.

Industry Segments

Financial information concerning industry segments, as defined by accounting principles generally accepted in the United States, for the years ended December 31, 2016, 2015 and 2014 is included in Note 23 - Segment Information in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K and incorporated herein.

Laws and Regulations

Overview

Our natural gas and coal mining operations are subject to various types of federal, state and local laws and regulations. Regulations relating to our operations include permitting and other licensing requirements; water withdrawal and procurement for well stimulation purposes; well drilling and casing; well production; well plugging; venting or flaring of natural gas; pipeline compression and transmission of natural gas and liquids; reclamation and restoration of properties after natural gas or coal mining operations are completed; storage, transportation and disposal of materials used or generated by gas and mining operations; the calculation, reporting and disbursement of taxes; gathering of gas production in certain circumstances; surface subsidence from underground mining; discharge of water from coal mining operations; air quality standards; protection of wetlands; endangered plant and wildlife protection; and employee health and safety. Numerous governmental permits and approvals under these laws and regulations are required for gas and mining operations. Lastly, the electric power generation industry is subject to extensive regulation regarding the environmental impact of its power generation activities, which could affect demand for our natural gas and coal products.

Compliance with these laws has substantially increased the cost of natural gas production and mining of coal for all domestic natural gas and coal producers. We also post performance bonds or letters of credit pursuant to state oil and gas laws and regulations to guarantee reclamation of gas well sites and plugging of gas wells. We post surety performance bonds or letters of credit pursuant to federal and state mining laws and regulations for the estimated costs of reclamation and mine closing, often including the cost of treating mine water discharge. We endeavor to conduct our natural gas and mining operations in compliance with all applicable federal, state and local laws and regulations. However, because of extensive and comprehensive regulatory requirements against a backdrop of variable geologic and seasonal conditions, permit exceedances and violations during natural gas and mining operations can and do occur. The possibility exists that new legislation or regulations may be adopted which would have a significant impact on our natural gas and coal mining operations or our customers' ability to use our gas and coal and may require us or our customers to change their operations significantly or incur substantial costs.

CONSOL Energy is committed to complying with all laws and regulations. This commitment is evident in CONSOL Energy's demonstrated cost and effort to abate and control pollution and/or contamination at its facilities. CONSOL Energy made capital expenditures for environmental control facilities of approximately $0.6 million, $18.4 million, and $19.0 million in the years ended December 31, 2016, 2015 and 2014, respectively. CONSOL Energy does not expect to have any capital expenditures in 2017 for environmental control facilities.

Environmental Laws

Clean Air Act and Related Regulations. The federal Clean Air Act (CAA) and corresponding state laws and regulations regulate air emissions primarily through permitting and/or emissions control requirements. This affects natural gas production and processing operations as well as coal mining, coal handling, and processing.

We are required to obtain pre-approval for construction or modification of certain facilities, to meet stringent air permit requirements, or to use specific equipment, technologies or best management practices to control emissions. On August 16, 2012, the U.S. Environmental Protection Agency (EPA) published final revisions to the New Source Performance Standards (NSPS) to regulate emissions of volatile organic compounds (VOCs) and sulfur dioxide (SO₂) from various oil and gas exploration, production, processing and transportation facilities. Additionally, revisions were made to the National Emission Standards for Hazardous Air Pollutants (NESHAPS) to further regulate emissions from the oil and natural gas production sector and the transmission and storage of natural gas. Section 111 of the CAA authorized the EPA to develop technology based standards which apply to specific categories of stationary sources. On June 3, 2016, the EPA finalized updates to the final New Source Performance Standards (NSPS) that created new standards for the regulation of methane and VOC emission sources. The rule includes requirements for new fugitive emission and leak detection testing and reporting requirements. Also on June 3, 2016, the EPA published the final Source Determination Rule which clarified the use of the term “adjacent” in determining Title V air permitting requirements as they apply to the oil and natural gas industry for major sources of air emissions. On August 1, 2016 these updates to the NSPS were challenged in the D.C. Circuit Court of Appeals by industry and state associations and a request for administrative reconsideration was also filed. Additionally, 15 states filed suit and asked the Court of Appeals to review the need for the changes.

On November 30, 2016, the EPA finalized amendments to the Petroleum and Natural Gas Systems source category (Subpart W) of the Greenhouse Gas Reporting Program (GHGRP). This final rule adds new monitoring methods for detecting leaks from oil and gas equipment in the petroleum and natural gas systems source category consistent with the leak detection methods in the NSPS. The action also adds emission factors for leaking equipment to be used in conjunction with these monitoring methods to calculate and report greenhouse gas (GHG) emissions resulting from equipment leaks. The NSPS final rule would add reporting

22

of GHG emissions from certain gathering and boosting systems, completions and workovers of oil wells using hydraulic fracturing, and blowdowns of natural gas transmission pipelines.

The CAA also indirectly and more significantly affects the U.S. coal industry by extensively regulating the air emissions of coal-fired electric power generating plants operated by our customers. Coal contains impurities, such as sulfur, mercury and other constituents, many of which are released into the air when coal is burned. Carbon dioxide (CO₂), a regulated GHG, is also emitted when coal is burned. Environmental regulations governing emissions from coal-fired electric generating plants increase the costs to operate and could affect demand for coal as a fuel source and affect the volume of our sales. Moreover, additional environmental regulations increase the likelihood that existing coal-fired electric generating plants will be decommissioned, including plants to which CONSOL Energy sells coal to, and reduce the likelihood that new coal-fired plants will be built in the future.

In early 2012, the EPA promulgated or finalized several rules for New Source Performance Standards (NSPS) for coal- and oil- fired power plants which also have a negative effect on coal-generating facilities. The Utility Maximum Control Technology (UMACT) rule requires more stringent NSPS for particulate matter (PM), SO₂ and nitrogen oxides (NO_X) and the Mercury and Air Toxics Standards (MATS) rule requires new mercury and air toxic standards. In November 2012, the EPA published a notice of reconsideration of certain aspects of the UMACT and MATS rules. Following reconsideration in April 2013 and again in April 2014, the EPA promulgated final UMACT and MATS rules in November 2014 at which point the standards become applicable to new power plants. The final rules have higher emission limits, but the standards are still stringent and compliance with the rules is expensive.

The CAA requires the EPA to set National Ambient Air Quality Standards (NAAQS) for certain pollutants and the CAA identifies two types of NAAQS. Primary standards provide public health protection, including protecting the health of "sensitive" populations such as asthmatics, children, and the elderly. Secondary standards provide public welfare protection, including protection against decreased visibility and damage to animals, crops, vegetation, and buildings. On October 1, 2015, the EPA finalized the NAAQS for ozone pollution and reduced the limit to 70 parts per billion (ppb) from the previous 75 ppb standard. The final rule could have a large impact on both the oil and gas and coal mining industries as states would be required to update their permitting standards to meet these potentially unachievable limits. Six states have now filed a petition for review in the Court of Appeals for the D.C. Circuit.

On July 6, 2011, the EPA finalized a rule known as the Cross-State Air Pollution Rule (CSAPR). CSAPR regulates cross-border emissions of criteria air pollutants such as SO₂ and NO_X, as well as byproducts, fine particulate matter (PM_2.5) and ozone by requiring states to limit emissions from sources that "contribute significantly" to noncompliance with air quality standards for the criteria air pollutants. If the ambient levels of criteria air pollutants are above the thresholds set by the EPA, a region is considered to be in "nonattainment" for that pollutant and the EPA applies more stringent control standards for sources of air emissions located in the region. In April 2014, the Supreme Court reversed a decision of the D.C. Circuit Court of Appeals that vacated the rule. Following remand and briefing the D.C. Circuit Court of appeals, in October 2014, granted a motion to lift a stay of the rule and allow the EPA to modify the CSAPR compliance deadline by three-years, setting the stage for issuance of the proposed rule. Implementation of CSAPR Phase 1 began in 2015, with Phase 2 scheduled to begin in 2017. On September 7, 2016, the EPA finalized an update to the CSAPR for the 2008 ozone NAAQS by issuing the final CSAPR Update. Starting in May 2017, this rule will reduce summertime (May - September) NO_X emissions from power plants in 22 states in the eastern United States.

On March 27, 2012, the EPA published its proposed NSPS for CO₂ emissions from new coal-powered electric generating units. The proposed rule would have applied to new power plants and to existing plants that make major modifications. If the rule had been adopted as proposed, only new coal-fired power plants with CO₂ capture and storage (CCS) could have met the proposed emission limits. Commercial scale CCS is not likely to be available in the near future, and if available, it may make coal-fired electric generation units uneconomical compared to new gas-fired electric generation units. On January 8, 2014, the EPA re-proposed NSPS for CO₂ for new fossil fuel fired power plants and rescinded the rules that were proposed on April 12, 2012.

On September 20, 2013, the EPA issued a new proposal to control carbon emissions from new power plants. Under the Clean Power Plan (CPP) proposal, the EPA would establish separate NSPS for CO₂ emissions for natural gas-fired turbines and coal-fired units. The proposed “Carbon Pollution Standard for New Power Plants” replaces the earlier proposal released by the EPA in 2012. On August 3, 2015, the EPA finalized the Carbon Pollution Standards to cut carbon emissions from new, modified and reconstructed power plants, which would have become effective on October 23, 2015.

On June 2, 2014, the EPA proposed additional CPP legislation to cut carbon emissions from existing power plants. Under this proposed rule, the EPA would create emission guidelines for states to follow in developing plans to address GHG emissions from existing fossil fuel-fired electric generating units. Specifically, the EPA is proposing state-specific rate-based goals for CO₂ emissions from the power sector, as well as guidelines for states to follow in developing plans to achieve the state-specific goals.

23

On August 3, 2015, the EPA finalized the CPP Rule to cut carbon pollution from existing power plants, which would have become effective on December 22, 2015. Numerous petitions challenging the CPP Rule have been consolidated into one case, West Virginia v. EPA. While the litigation is still ongoing at the circuit court level, a mid-litigation application to the Supreme Court resulted in a stay of the Clean Power Plan Rule. On September 27, 2016, the en banc D.C. Circuit heard oral argument in the case and a decision is expected in early 2017.

Clean Water Act. The federal Clean Water Act (CWA) and corresponding state laws affect our natural gas and coal operations by regulating discharges into surface waters. Permits requiring regular monitoring and compliance with effluent limitations and reporting requirements govern the discharge of pollutants into regulated waters. The CWA and corresponding state laws include requirements for: improvement of designated "impaired waters" (i.e., not meeting state water quality standards) through the use of effluent limitations; anti-degradation regulations which protect state designated "high quality/exceptional use" streams by restricting or prohibiting discharges; requirements to treat discharges from coal mining properties for non-traditional pollutants, such as chlorides, selenium and dissolved solids; requirements to minimize impacts and compensate for unavoidable impacts resulting from discharges of fill materials to regulated streams and wetlands; and requirements to dispose of produced wastes and other oil and gas wastes at approved disposal facilities. In addition, the Spill Prevention, Control and Countermeasure (SPCC) requirements of the CWA apply to all CONSOL Energy operations that use or produce fluids and require the implementation of plans to address any spills and the installation of secondary containment around all storage tanks. These requirements may cause CONSOL Energy to incur significant additional costs that could adversely affect our operating results, financial condition and cash flows.

Pursuant to a Congressional requirement in the EPA's 2010 budget appropriation, the EPA must conduct a comprehensive study of the potential adverse impact that hydraulic fracturing may have on water quality and public health. Hydraulic fracturing is a way of producing natural gas from tight rock formations such as the Marcellus shale and Utica shale. The EPA initiated the study in early January 2011 and the final assessment report was published on June 4, 2015. The draft report stated that hydraulic fracturing activities have not led to widespread, systemic impacts to drinking water resources. On December 13, 2016, the EPA released its final report on the impacts of hydraulic fracturing on drinking water. While the language was changed and included the possibility of impacts from hydraulic fracturing, it also included the guidance to industry and regulators on how the process can be done safely.

CONSOL Energy utilizes pipelines extensively for its natural gas, water and coal businesses. Mitigation permits from the Army Corps of Engineers (ACOE) are typically required for certain impacts these pipelines cause to streams and wetlands. On April 21, 2014 the EPA published a proposed rule called “Definition of ‘Waters of the United States’ (WoUS) Under the Clean Water Act.” The proposal would expand the scope of the CWA to include previously non-jurisdictional streams, wetlands, and waters, making these areas jurisdictional inter-coastal waters of the U.S. In February 2015 the EPA and ACOE issued a memorandum of understanding to withdraw the WoUS Interpretive Rule. The EPA published the latest version of the WoUS rule (the Clean Water Rule) on June 29, 2015, which was to become effective on August 28, 2015. However, on August 27, 2015, the District Court of North Dakota blocked implementation of the rule in 13 states. On October 9, 2015, the Court of Appeals for the Sixth Circuit blocked implementation of the rule nationwide. The U.S. Supreme Court will now decide which court has jurisdiction - federal appeals court or district courts. A decision is expected sometime in mid 2017.

Safety of Gas Transmission and Gathering Pipelines. On April 8, 2016, The U.S. Department of Transportation (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) published in the Federal Register a Notice of Proposed Rule Making (NPRM) that would significantly modify existing regulations related to reporting, impact, design, construction, maintenance, operations and integrity management of gas transmission and gathering pipelines. The proposed rule addresses four congressional mandates and six recommendations by the National Transportation Safety Board. The proposed rule broadens the scope of safety coverage both by adding new assessment and repair criteria for gas transmission pipelines, and by expanding these protocols to include pipelines not formerly regulated by the federal standards. This means extending regulatory requirements to transmission and gathering pipelines of 8 inches and greater in rural class 1 areas, which could increase timeframes and cost to complete projects.

Resource Conservation and Recovery Act. The federal Resource Conservation and Recovery Act (RCRA) and corresponding state laws and regulations affect natural gas operations and coal mining by imposing requirements for the treatment, storage and disposal of hazardous wastes. Facilities at which hazardous wastes have been treated, stored or disposed of are subject to corrective action orders issued by the EPA that could adversely affect our financial results, financial condition and cash flows. On December 28, 2016 the EPA entered into a consent order to resolve outstanding litigation brought by environmental and citizen groups regarding the applicability of RCRA to wastes from oil and gas development activities. The consent order requires the EPA to revise the applicability determination by March 15, 2019.

24

In 2010, the EPA proposed options for the regulation of Coal Combustion Residuals (CCRs) from the electric power sector as either hazardous waste or non-hazardous waste. On December 19, 2014, the EPA announced the first national regulations for the disposal of CCRs from electric utilities and independent power producers under RCRA. On April 17, 2015, the EPA finalized these regulations under the solid waste provisions (Subtitle D) of RCRA and not the hazardous waste provisions (Subtitle C) which became effective on October 19, 2015. The EPA affirms in the preamble to the final rule that “this rule does not apply to CCR placed in active or abandoned underground or surface mines.” Instead, “the U.S. Department of Interior (DOI) and the EPA will address the management of CCR in mine fills in a separate regulatory action(s).” On November 3, 2015, the EPA published the final rule Effluent Limitations Guidelines and Standards (ELG), revising the regulations for the Steam Electric Power Generating category which became effective on January 4, 2016. The rule sets the first federal limits on the levels of toxic metals in wastewater that can be discharged from power plants, based on technology improvements in the steam electric power industry over the last three decades. The combined effect of the CCR and ELG regulations has forced power generating companies to close existing ash ponds and will likely force the closure of certain older existing coal burning power plants that can’t comply with the new standards.

Surface Mining Control and Reclamation Act. The federal Surface Mining Control and Reclamation Act (SMCRA) establishes minimum national operational and reclamation standards for all surface mines, as well as most aspects of underground mines. SMCRA requires that comprehensive environmental protection and reclamation standards be met during the course of and following completion of mining activities. Permits for all mining operations must be obtained from the U.S. Office of Surface Mining (OSM) or, where state regulatory agencies have adopted federally approved state programs under SMCRA, the appropriate state regulatory authority. States that operate federally approved state programs may impose standards which are more stringent than the requirements of SMCRA and OSM's regulations and in many instances have done so. Our active mining complexes are located in Pennsylvania which has primary jurisdiction for enforcement of SMCRA through its approved state program. In addition, SMCRA imposes a reclamation fee on all current mining operations, the proceeds of which are deposited in the Abandoned Mine Reclamation Fund (AML Fund), which is used to restore unreclaimed and abandoned mine lands mined before 1977. The current per ton fee is $0.28 per ton for surface mined coal and $0.12 per ton for underground mined coal. These fees are currently scheduled to be in effect until September 30, 2021.

Federal and state laws require bonds to secure our obligations to reclaim lands used for mining and to satisfy other miscellaneous obligations. These bonds are typically renewable on a yearly basis. Surety bond costs have increased while the market terms of surety bonds have generally become less favorable. It is possible that surety-bond issuers may refuse to renew bonds or may demand additional collateral. Any failure to maintain, or inability to acquire, surety bonds that are required by state and federal laws would have a material adverse effect on our ability to produce coal, which could adversely affect our business, financial condition, results of operations, liquidity and cash flows.

Excess Spoil, Coal Mine Waste, Diversions, and Buffer Zones for Perennial and Intermittent Streams. The OSM has issued final amendments to regulations concerning stream buffer zones, stream channel diversions, excess spoil, and coal mine waste to comply with an order issued by the U.S. District Court for the District of Columbia on February 20, 2014, which vacated the stream buffer zone rule that was published December 12, 2008. On July 27, 2015, the OSM published the proposed Stream Protection Rule (SPR). After much debate and thousands of comments, the final SPR was published by the OSM in the Federal Register on December 20, 2016. The final SPR requires the restoration of the physical form, hydrologic function, and ecological function of the segment of a perennial or intermittent stream that a permittee mines through. Additionally, it requires that the post-mining surface configuration of the reclaimed mine site include a drainage pattern, including ephemeral streams, similar to the pre-mining drainage pattern, with exceptions for stability, topographical changes, fish and wildlife habitat, etc. The rule also requires the establishment of a 100-foot-wide streamside vegetative corridor of native species (including riparian species, when appropriate) along each bank of any restored or permanently-diverted perennial, intermittent, or ephemeral stream. This rulemaking is highly anticipated to be subject to Legislative and Executive branch actions to overturn or significantly modify the rule.

Federal Regulation of the Sale and Transportation of Natural Gas

Regulations and orders set forth by the Federal Energy Regulatory Commission (FERC) impact our natural gas business to a certain degree. Although the FERC does not directly regulate our natural gas production activities, the FERC has stated that it intends for certain of its orders to foster increased competition within all phases of the natural gas industry. Additionally, the FERC continues to review its transportation regulations, including whether to allocate all short-term capacity on the basis of competitive auctions and whether changes to its long-term transportation policies may also be appropriate to avoid a market bias toward short-term contracts. The FERC has also issued numerous orders confirming the sale and abandonment of natural gas gathering facilities previously owned by interstate pipelines and acknowledging that if the FERC does not have jurisdiction over services provided by these facilities, then such facilities and services may be subject to regulation by state authorities in accordance with state law. We own certain natural gas pipeline facilities that we believe meet the traditional tests which the FERC has used to establish a pipeline's status as a gatherer not subject to the FERC jurisdiction.

25

Health and Safety Laws

Occupational Safety and Health Act. Our gas operations are subject to regulation under the federal Occupational Safety and Health Act (OSHA) and comparable state laws in some states, all of which regulate health and safety of employees at our natural gas operations. Also, OSHA's hazardous communication standard requires that information be maintained about hazardous materials used or produced by our natural gas operations and that this information be provided to employees, state and local governments and the public.

Mine Safety. Legislative and regulatory changes have required us to purchase additional safety equipment, construct stronger seals to isolate mined out areas, and engage in additional training. We have also experienced more aggressive inspection protocols and with new regulations the amount of civil penalties has increased. The actions taken thus far by federal and state governments include requiring:

• the caching of additional supplies of self-contained self-rescuer (SCSR) devices underground;

• the purchase and installation of electronic communication and personal tracking devices underground;

• the purchase and installation of proximity detection services on continuous miner machines;

• the placement of refuge chambers, which are structures designed to provide refuge for groups of miners during a mine emergency when evacuation from the mine is not possible, which will provide breathable air for 96 hours;

• the replacement of existing seals in worked-out areas of mines with stronger seals;

• the purchase of new fire resistant conveyor belting underground;

• additional training and testing that creates the need to hire additional employees;

• more stringent rock dusting requirements; and

• the purchase of personal dust monitors for collecting respirable dust samples from certain miners.

On October 2, 2015, the Mine Safety and Health Administration (MSHA) published proposed rules for underground coal mining operations concerning proximity detection systems for coal hauling machines and scoops. On January 15, 2015, MSHA published a final rule requiring underground coal mine operations to equip continuous mining machines, except full-face continuous mining machines, with proximity detection systems. The proximity detection system strengthens protection for miners by reducing the potential of pinning, crushing and striking hazards that result in accidents involving life-threatening injuries and death. The final rule became effective March 15, 2015 and included a phased in schedule for newly manufactured and in-service equipment. In 2010 MSHA rolled out the “End Black Lung, Act Now” initiative. As a result, MSHA implemented a new final rule on August 1, 2014 to lower miners’ exposure to respirable coal mine dust including using the new Personal Dust Monitor (PDM) technology. This final rule was implemented in three phases. The first phase began August 1, 2014 and utilizes the current gravimetric sampling device to take full shift dust samples from the current designated occupations and areas. It also requires additional record keeping and immediate corrective action in the event of overexposure. The second phase began February 1, 2016 and requires additional sampling for designated and other occupations using the new continuous personal dust monitor (CPDM) technology, which provides real time dust exposure information to the miner. CONSOL Energy ordered the necessary CPDM equipment required to meet compliance with the new rule at a cost of $2 million. We also hired Dust Coordinators and Dust Technicians to meet the staffing demand to manage compliance with the new rule. The final phase of the rule was effective on August 1, 2016. when the current respirable dust standard was reduced from 2.0 to 1.5mg/m3 for designated occupations and from 1.0 to 0.5mg/m3 for Part 90 Miners.

Black Lung Legislation. Under federal black lung benefits legislation, each coal mine operator is required to make payments of black lung benefits or contributions to:

• current and former coal miners totally disabled from black lung disease;

• certain survivors of a coal miner who dies from black lung disease or pneumoconiosis; and

• a trust fund for the payment of benefits and medical expenses to claimants whose last mine employment was before January 1, 1970, where no responsible coal mine operator has been identified for claims (where a coal miner's last coal employment was after December 31, 1969), or where the responsible coal mine operator has defaulted on the payment of such benefits. The trust fund is funded by an excise tax on U.S. production of up to $1.10 per ton for deep mined coal and up to $0.55 per ton for surface-mined coal, neither amount to exceed 4.4% of the gross sales price.

The Patient Protection and Affordable Care Act (PPACA) made two changes to the Federal Black Lung Benefits Act. First, it provided changes to the legal criteria used to assess and award claims by creating a legal presumption that miners are entitled to benefits if they have worked at least 15 years in underground coal mines, or in similar conditions, and suffer from a totally disabling lung disease. To rebut this presumption, a coal company would have to prove that a miner did not have black lung or that the disease was not caused by the miner's work. Second, it changed the law so black lung benefits will continue to be paid to dependent survivors when the miner passes away, regardless of the cause of the miner's death. The changes have increased the

26

cost to CONSOL Energy of complying with the Federal Black Lung Benefits Act. In addition to the federal legislation, we are also liable under various state statutes for black lung claims.

Other State and Local Laws Related to Our Natural Gas Business

Regulation Affecting Gas Operations. Our natural gas operations are also subject to regulation at the state and in some cases, county, municipal and local governmental levels. Such regulation includes requiring permits for the siting and construction of well pads and roads, drilling of wells, bonding requirements, protection of ground water and surface water resources and protection of drinking water supplies, the method of drilling and casing wells, the surface use and restoration of well sites, gas flaring, the plugging and abandoning of wells, the disposal of fluids used in connection with operations and natural gas operations producing coalbed methane in relation to active mining. A number of states have either enacted new laws or may be considering the adequacy of existing laws affecting gathering rates and/or services. Other state regulation of gathering facilities generally includes various safety, environmental and in some circumstances, nondiscriminatory take requirements but does not generally entail rate regulation. Thus, natural gas gathering may receive greater regulatory scrutiny of state agencies in the future. Our gathering operations could be adversely affected should they be subject in the future to increased state regulation of rates or services, although we do not believe that they would be affected by such regulation any differently than other natural gas producers or gatherers. However, these regulatory burdens may affect profitability, and we are unable to predict the future cost or impact of complying with such regulations.

Ownership of Mineral Rights. CONSOL Energy acquires ownership or leasehold rights to oil and gas properties and coal properties prior to conducting operations on those properties. As is customary in the natural gas and coal industries, we have generally conducted only a summary review of the title to oil and gas rights and coal rights that are not in our development plans, but which we believe we control. This summary review is conducted at the time of acquisition or as part of a review of our land records to determine control of mineral rights. Given CONSOL Energy's long history as a coal producer, we believe we have a well-developed ownership position relating to our coal control; however, our ownership of oil and gas rights, particularly those rights that we acquired in connection with our historic coal operations and some of the rights we acquired in 2010, as part of an acquisition, are less developed. As we continue to review our land records and confirm title in anticipation of development, we expect that adjustments to our ownership position (either increases or decreases) will be required.

Prior to the commencement of development operations on natural gas and coal properties, we conduct a thorough title examination and perform curative work with respect to significant defects. We generally will not commence operations on a property until we have cured any material title defects on such property. We are typically responsible for the cost of curing any title defects. In addition, the acquisition of the necessary rights may not be feasible in some cases. Our discovering natural gas title defects which we are unable to cure may adversely impact our ability to develop those properties and we may have to reduce our estimated gas reserves including our proved undeveloped reserves. We have completed title work on substantially all of our natural gas and coal producing properties and believe that we have satisfactory title to our producing properties in accordance with standards generally accepted in the industry.

ITEM 1A. Risk Factors

Investment in our securities is subject to various risks, including risks and uncertainties inherent in our business. The following sets forth factors related to our business, operations, financial position or future financial performance or cash flows which could cause an investment in our securities to decline and result in a loss.

Deterioration in the global economic conditions in any of the industries in which our customers operate, or a worldwide financial downturn, or negative credit market conditions may have a materially adverse effect on our liquidity, results of operations, business and financial condition that we cannot predict.

Economic conditions in a number of industries in which our customers operate, such as electric power generation and steel-making, substantially deteriorated in recent years and reduced the demand for natural gas and coal. The general economic challenges for some of our customers continued in 2016 and the outlook is uncertain. In addition, liquidity is essential to our business and developing our assets. Renewed or continued weakness in the economic conditions of any of the industries we serve or are served by our customers could adversely affect our business, financial condition, results of operation and liquidity in a number of ways. For example:

• demand for natural gas and electricity in the United States is impacted by industrial production, which if weakened would negatively impact the revenues, margins and profitability of our natural gas and thermal coal business;

• the tightening of credit or lack of credit availability to our customers could adversely affect our ability to collect our trade receivables;

• our ability to access the capital markets may be restricted at a time when we would like, or need, to raise capital for our business including for exploration and/or development of our natural gas or coal reserves; and

• a decline in our creditworthiness, which may require us to post letters of credit, cash collateral, or surety bonds to secure certain obligations, all of which would have an adverse effect on our liquidity.

Prices for natural gas, natural gas liquids and coal are volatile and can fluctuate widely based upon a number of factors beyond our control including oversupply relative to the demand available for our products, weather and the price and availability of alternative fuels. An extended decline in the prices we receive for our natural gas, natural gas liquids and coal will adversely affect our business, operating results, financial condition and cash flows.

Our financial results are significantly affected by the prices we receive for our natural gas, natural gas liquids and coal.

Our E&P division’s products (natural gas, natural gas liquids, oil and condensate) accounted for approximately 42% of the total company outside sales revenues from continuing operations in 2016, with natural gas and natural gas liquids representing 97% of the E&P division’s outside sales revenues. Natural gas, natural gas liquids, oil and condensate prices are very volatile and can fluctuate widely based upon supply from energy producers relative to demand for these products and other factors beyond our control. The sale to Murray Energy in 2013 of almost one half of our thermal coal production and the sale of our Buchanan Mine in 2016 increased our exposure to fluctuations in the price of natural gas, natural gas liquids, oil and condensate.

In particular, while demand for natural gas has recovered to pre-recession levels, the U.S. natural gas industry continues to face concerns of oversupply due to the success of Marcellus and other new shale plays. The oversupply of natural gas in 2012 resulted in domestic prices hovering around ten year lows, and drilling continued in these plays, despite these lower gas prices, to meet drilling commitments. Although gas prices recovered somewhat during 2013 and the first quarter of 2014, they again significantly declined in the latter part of 2014 due to oversupply and remained at depressed levels throughout 2015 and 2016.

Our natural gas operations are geographically concentrated in the mid-Atlantic states. The success of the Marcellus Shale and Utica plays has resulted in growth in natural gas production in this region with production per day in Pennsylvania, West Virginia and Ohio more than doubling since 2011. Traditionally, natural gas produced in the mid-Atlantic states sold at a premium to the benchmark Louisiana Henry Hub prices. However, as Appalachian production increased this premium narrowed and during 2014 and continuing into 2015 and 2016, the spot prices at some Appalachian hubs fell below Henry Hub prices. This decline, or negative basis, to the Henry Hub price is forecasted to continue in future years. The oversupply in the Appalachian Basin may persist if current pipeline projects to move gas out of the basin are delayed by permitting or environmental lawsuits.

An extended period of lower natural gas prices can negatively affect us in several other ways. These include reduced cash flow, which decreases funds available for capital expenditures to replace reserves or increase production. For example, in light of the low natural gas prices continuing from 2014 into 2015, we substantially decreased our 2016 capital expenditures and the drilling of new shale wells. In 2017, we expect our capital expenditures to increase to approximately $555 million from $227

28

million in 2016. Also, our access to other sources of capital, such as equity or long-term debt markets, could be severely limited or unavailable. Additionally, lower natural gas prices may reduce the amount of natural gas that we can produce economically. This may result in our having to make substantial downward adjustments to our estimated proved reserves. If this occurs, or if our estimates of development costs increase, production data factors change or our exploration results deteriorate, accounting rules may require us to write down, as a non-cash charge to earnings, the carrying value of our natural gas properties. We are required to perform impairment tests on our assets whenever events or changes in circumstances lead to a reduction of the estimated useful life or estimated future cash flows that would indicate that the carrying amount may not be recoverable or whenever management's plans change with respect to those assets. For example, in the second quarter of 2015, we had an impairment charge of approximately $829 million for our natural gas assets, primarily shallow oil and gas assets. We may incur impairment charges in the future, which could have an adverse effect on our results of operations in the period taken.

We have increased development activity in areas of shale formations which may also contain natural gas liquids, condensate and/or oil. The prices for natural gas liquids, condensate and oil are also volatile for reasons similar to those described above regarding natural gas. As a result of increasing supply, condensate and oil prices have exhibited great volatility. In addition, similar to the oversupply of natural gas, increased drilling activity by third-parties in formations containing natural gas liquids has led to a decline of over 60% since 2014 in the uplift we receive, on an Mcfe equivalent basis when excluding hedging impact, from natural gas liquids. Our results of operation may be adversely affected by a continued depressed level of or further downward fluctuations in natural gas liquids, condensate and oil prices.

Apart from issues with respect to the supply of products we produce, demand can fluctuate widely due to a number of matters beyond our control, including:

• changes in the consumption pattern of industrial consumers, electricity generators and residential users of electricity and natural gas;

• weather conditions in our markets which affect the demand for natural gas and thermal coal (for example, the unusually warm 2015 - 2016 winter left utilities with large coal stockpiles and depressed the demand for thermal coal);

• with respect to thermal coal, the price and availability of natural gas and the price and supply of imported liquefied natural gas;

• with respect to natural gas, the price and availability of thermal coal;

• technological advances affecting energy consumption;

• the costs, availability and capacity of transportation infrastructure;

• proximity and capacity of natural gas pipelines and other transportation facilities; and

• the impact of domestic and foreign governmental laws and regulations, including environmental and climate change regulations and regulations affecting the coal mining industry and coal-fired power plants, and delays in the receipt of, failure to receive, failure to maintain or revocation of necessary governmental permits.

The coal industry also faces concerns with respect to oversupply from time to time. For example, U.S. coal exports decreased by 32% during the first half of 2016 compared with the first half of 2015, as global supply exceeded demand for both thermal and metallurgical coal. Our average sales price per ton sold in 2016 declined 23% from 2015 due to imbalanced supply and demand, and a substantial or extended decline in the prices we receive for our coal could adversely affect our business, results of operations, financial condition, cash flows and liquidity.

Foreign currency fluctuations could adversely affect the competitiveness of our coal and natural gas liquids abroad.

We compete in international markets against coal produced in other countries. Coal is sold internationally in U.S. dollars and, as a result, general economic conditions in foreign markets and changes in foreign currency exchange rates may provide our foreign competitors with a competitive advantage. As a result, mining costs in competing producing countries may be reduced in U.S. dollar terms based on currency exchange rates, providing an advantage to foreign coal producers. If our competitors’ currencies decline against the U.S. dollar or against our foreign customers’ local currencies, those competitors may be able to continue to offer lower prices for coal to our customers. Furthermore, if the currencies of our overseas customers were to significantly decline in value in comparison to the U.S. dollar, those customers may seek decreased prices for the coal we sell to them. We also expect in the future that an international market will develop for exporting domestic natural gas and natural gas liquids. Consequently, currency fluctuations could adversely affect the competitiveness of our products in international markets, which could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

If our coal customers do not extend existing contracts or do not enter into new multi-year coal sales contracts on favorable terms, profitability of CONSOL Energy's operations could be adversely affected.

During the year ended December 31, 2016, approximately 65% of the coal CONSOL Energy produced from continued operations was sold under multi-year sales contracts. If a substantial portion of our multi-year sales contracts are modified or terminated, if force majeure is exercised, or if we are unable to replace or extend the contracts or new contracts are priced at lower levels, our profitability would be adversely affected. The profitability of our multi-year sales coal supply contracts depends on a variety of factors, which vary from contract to contract and fluctuate during the contract term, including our production costs and other factors. Price changes, if any, provided in long-term supply contracts may not reflect our cost increases, and therefore, increases in our costs may reduce our profit margins. In addition, during periods of declining market prices, provisions in our long-term coal contracts for adjustment or renegotiation of prices and other provisions may increase our exposure to short-term coal price and electric power price volatility. As a result, we may not be able to obtain long-term agreements at favorable prices compared to either market conditions, as they may change from time to time, or our cost structure, which may reduce our profitability.

The loss of, or significant reduction in, purchases by our largest coal customers or the failure of any of our customers to buy and pay for coal they committed to purchase could adversely affect our business, financial condition, results of operation and cash flows.

For the year ended December 31, 2016, we derived over 10% of our coal sales revenue from two coal customers individually and approximately 40% of our total sales revenue were derived from our four largest coal customers. At December 31, 2016, we had approximately nine coal supply agreements with these top two customers that expire at various times from 2017 to 2018. There are inherent risks whenever a significant percentage of total revenues are concentrated with a limited number of customers. Revenues from our largest customers may fluctuate from time to time based on numerous factors, including market conditions, which may be outside of our control. If any of our largest customers experience declining revenues due to market, economic or competitive conditions, we could be pressured to reduce the prices that we charge for our coal, which could have an adverse effect on our margins, profitability, cash flows and financial position. In addition, if any customers were to significantly reduce their purchases of coal from us, including by failing to buy and pay for coal they committed to purchase in sales contracts, our business, financial condition, results of operations and cash flows could be adversely affected.

Our ability to collect payments from our customers could be impaired if their creditworthiness declines or if they fail to honor their contracts with us.

Our ability to receive payment for natural gas and coal sold and delivered depends on the continued creditworthiness of our customers. Many utilities have sold their power plants to non-regulated affiliates or third parties that may be less creditworthy, thereby increasing the risk we bear with respect to payment default. These new power plant owners may have credit ratings that are below investment grade. In addition, some of our customers have been adversely affected by the current economic downturn, which may impact their ability to fulfill their contractual obligations. Competition with other coal suppliers could force us to extend credit to customers and on terms that could increase the risk we bear with respect to payment default. We also have a contract to supply coal to an energy trading and brokering customer under which that customer sells coal to end users. If the creditworthiness of our energy trading and brokering customer declines, we may not be able to collect payment for all coal sold and delivered to this customer. If the creditworthiness of our customers declines significantly, our business could be adversely affected. In addition, if customers refuse to accept shipments of our coal for which they have an existing contractual obligation, our revenues will decrease and we may have to reduce production at our mines until our customers’ contractual obligations are honored. Our inability to collect payment from counterparties to our sales contracts may have a materially adverse effect on our business, financial condition, results of operations and cash flows.

Our natural gas business depends on gathering, processing and transportation facilities owned by others and the disruption of, capacity constraints in, or proximity to pipeline systems could limit sales of our natural gas and natural gas liquids. Similarly, the availability and reliability of transportation facilities and fluctuations in transportation costs could affect the demand for our coal or impair our ability to supply coal to our customers.

We gather, process and transport our natural gas to market by utilizing pipelines and facilities owned by others. If pipeline or facility capacity is limited, or if pipeline or facility capacity is unexpectedly disrupted for any reason, our natural gas sales and/or sales of natural gas liquids could be limited, reducing our profitability. If we cannot access processing pipeline transportation facilities, we may have to reduce our production of natural gas. If our sales of natural gas or natural gas liquids are reduced because of transportation or processing constraints, our revenues will be reduced and our unit costs will also increase. If pipeline quality standards change, we might be required to install additional processing equipment which could increase our

30

costs. The pipeline could also curtail our flows until the natural gas delivered to their pipeline is in compliance. Any reduction in our production of natural gas or increase in our costs could materially adversely affect our business, financial condition, results of operations and cash flows.

Additionally, we have various firm transportation, natural gas processing, gathering and other agreements in place, many of which have minimum volume delivery commitments. Lower commodity prices may lead to reductions in our drilling program, which may result in insufficient production to utilize our full firm transportation and processing capacity. We are obligated to pay fees on minimum volumes to our service providers regardless of actual volume throughput. If we have insufficient production to meet the minimum volumes, our cash flow from operations will be reduced, which may require us to reduce or delay our planned investments and capital expenditures or seek alternative means of financing, all of which may have a material adverse effect our business, financial condition, results of operations and cash flows.

Transportation logistics play an important role in allowing us to supply coal to our customers. Any significant delays, interruptions or other limitations on the ability to transport our coal could negatively affect our operations. Our coal is transported from our mining complex by rail, truck or a combination of these methods. To reach markets and end customers, our coal may also be transported by barge or by ocean vessels loaded at terminals. Disruption of transportation services because of weather-related problems, strikes, lock-outs, terrorism, governmental regulation, third-party action or other events could temporarily impair our ability to supply coal to customers and adversely affect our profitability. In addition, transportation costs represent a significant portion of the delivered cost of coal and, as a result, the cost of delivery is a critical factor in a customers’ purchasing decision. Increases in transportation costs, including increases resulting from emission control requirements and fluctuation in the price of diesel fuel and demurrage, could make our coal less competitive. Any disruption of the transportation services we use or increase in transportation costs could have a materially adverse effect on our business, financial condition, results of operations and cash flows.

Competition within the natural gas and coal industries may adversely affect our ability to sell our products. Increased competition or a loss of our competitive position could adversely affect our sales of, or our prices for, our natural gas and coal products, which could impair our profitability.

The natural gas industry is intensely competitive with companies from various regions of the United States. We compete with these companies and we may compete with foreign companies for domestic sales. Many of the companies we compete with are larger and have greater financial, technological, human and other resources. If we are unable to compete, our company, our operating results and financial position may be adversely affected. In addition, larger companies may be able to pay more to acquire new natural gas properties for future exploration, limiting our ability to replace the natural gas we produce or to grow our production. Our ability to acquire additional properties and to discover new natural gas resources also depends on our ability to evaluate and select suitable properties and to consummate these transactions in a highly competitive environment.

We compete with other coal producers primarily on the basis of price, coal quality, transportation costs and reliability. We compete with coal producers in various regions of the United States and with some foreign coal producers for domestic sales primarily to electric power generators. Demand for our thermal coal by our principal electric power generator customers is affected by the delivered price of competing coals, other fuel supplies and alternative generating sources, including nuclear, natural gas, oil and renewable energy sources, such as hydroelectric and wind power. The domestic coal industry has experienced consolidation in recent years, including consolidation among some of our major competitors. In addition, substantial overcapacity exists in the coal industry and most large coal companies have filed bankruptcy proceedings which could enable them to lower their production costs and thereby reduce the price for their coal. We cannot assure you that the result of current or further consolidation in the coal industry or current or future bankruptcy proceedings of our coal competitors will not adversely affect our competitive position. We also compete with both domestic and foreign coal producers for sales in international markets. We sell coal to foreign electricity generators, which sales are significantly affected by international demand and competition. Potential changes to international trade agreements, trade concessions or other political and economic arrangements may benefit coal producers operating in countries other than the United States. We cannot assure you that we will be able to compete on the basis of price or other factors with companies that in the future may benefit from favorable foreign trade policies or other arrangements.

Any reduction in our ability to compete in natural gas or coal markets could have a material adverse effect on our business, financial condition, results of operations and cash flows.

The characteristics of coal may make it costly for electric power generators and other coal users to comply with various environmental standards regarding the emissions of impurities released when coal is burned which could cause utilities to replace coal-fired power plants with alternative fuels. In addition, various incentives have been proposed to encourage the generation of electricity from renewable energy sources. A reduction in the use of coal

31

for electric power generation could decrease the volume of our domestic coal sales and adversely affect our results of operations.

Coal contains impurities, including sulfur, mercury, chlorine and other elements or compounds, many of which are released into the air along with fine particulate matter and carbon dioxide when it is burned. Complying with regulations on these emissions can be costly for electric power generators. For example, in order to meet the federal Clean Air Act limits for sulfur dioxide emissions from electric power plants, coal users will need to install scrubbers, use sulfur dioxide emission allowances (some of which they may purchase) or switch to other fuels. Each option has limitations. Lower sulfur coal may be more costly to purchase on an energy basis than higher sulfur coal depending on mining and transportation costs. The cost of installing scrubbers is significant and emission allowances may become more expensive as their availability declines. Switching to other fuels may require expensive modification of existing plants. Because higher sulfur coal currently accounts for a significant portion of our sales, the extent to which electric power generators switch to alternative fuel could materially affect us. Recent EPA rulemaking proceedings requiring additional reductions in permissible emission levels of impurities by coal-fired plants will likely make it more costly to operate coal-fired electric power plants and may make coal a less attractive fuel alternative for electric power generation in the future. Examples are (i) implementation of Phase 1 of the Cross-State Air Pollution Rule (CSAPR) that began in May 2015 with implementation of Phase 2 planned to begin in 2017; (ii) on December 3, 2015 the EPA issued the proposed CSAPR Update Rule to require reductions of seasonal nitrogen oxides (NOX) emissions from power plants in 23 of the original 28 proposed Eastern states to address interstate ozone air quality impacts for downwind states; (iii) on October 1, 2015 the EPA finalized a revised National Ambient Air Quality Standards (NAAQS) for ozone pollution and reduced the limit to 70 parts per billion from the previous 75 parts per billion standard; and (iv) promulgation in 2011 of the Utility Maximum Achievable Control Technology (Utility MACT) rule, better known as the Mercury and Air Toxics Standard (MATS) rule, which included more stringent new source performance standards (NSPS) for particulate matter (PM), mercury, sulfur dioxide (SO2) and nitrogen oxides (NOX), for new and existing coal-fired power plants (amended in November 2014). On June 29, 2015, the U.S. Supreme Court rejected the EPA MATS rule, ruling that the agency unreasonably overlooked the costs associated with the regulation, and sent the rule back to the D.C. Circuit Court to determine whether to remand and allow the EPA to address the rule's deficiencies or to vacate and nullify the rule; nevertheless most coal-fired electric power generators have already taken steps to comply with the rule. Six states have filed petitions for review of the new EPA NAAQS ozone pollution standard with the D.C. Circuit Court.

On October 14, 2014, the EPA Clean Water Act Section 316(b) rulemaking went into effect which requires new and existing power plants, including coal and natural gas-fired plants to reduce fish mortality caused by their cooling water intake structures through either the installation of technologies or the reduction of intake velocity.

Apart from actual and potential regulation of emissions, waste water, and solid wastes from coal-fired plants, state and federal mandates for increased use of electricity from renewable energy sources could have an impact on the market for our coal. Several states have enacted legislative mandates requiring electricity suppliers to use renewable energy sources to generate a certain percentage of power. There have been numerous proposals to establish a similar uniform, national standard although none of these proposals have been enacted to date. Possible advances in technologies and incentives, such as tax credits, to enhance the economics of renewable energy sources could make these sources more competitive with coal. Any reductions in the amount of coal consumed by domestic electric power generators as a result of current or new standards for the emission of impurities or incentives to switch to alternative fuels or renewable energy sources could reduce the demand for our coal, thereby reducing our revenues and adversely affecting our business and results of operations.

Regulation of greenhouse gas emissions may increase our operating costs and reduce the value of our natural gas and coal assets and such regulation, as well as uncertainty concerning such regulation could adversely impact the market for natural gas and coal, as well as for our securities.

While climate change legislation in the U.S. is unlikely in the next several years, the issue of global climate change continues to attract considerable public and scientific attention with widespread concern about the impacts of human activity, especially the emissions of greenhouse gases (GHGs) such as carbon dioxide and methane. Combustion of fossil fuels, such as the natural gas and coal we produce, results in the creation of carbon dioxide emissions into the atmosphere by natural gas and coal end-users, such as coal-fired electric power generation plants. Numerous proposals have been made and are likely to continue to be made at the international, national, regional and state levels of government that are intended to limit emissions of GHGs. Several states have already adopted measures requiring reduction of GHGs within state boundaries. Other states have elected to participate in voluntary regional cap-and-trade programs like the Regional Greenhouse Gas Initiative (RGGI) in the northeastern U.S.

32

The EPA, under the Climate Action Plan, has elected to regulate GHGs under the Clean Air Act (CAA) to limit emissions of carbon dioxide (CO2) from coal-fired and natural gas-fired power plants. On September 20, 2013, the EPA re-proposed New Source Performance Standards (NSPS) for CO2 from new power plants and on June 2, 2014, the EPA re-proposed NSPS for CO2 from existing and modified/reconstructed power plants, which rescinded the rules that were originally proposed in 2012. On August 3, 2015, the EPA finalized the Carbon Pollution Standards to cut carbon emissions from new, modified and reconstructed power plants, which became effective on October 23, 2015. In another proposed rulemaking related to CO2 emissions, on June 2, 2014, the EPA proposed the Clean Power Plan Rule to cut carbon emissions from existing power plants. Under this proposed rule, the EPA would create emission guidelines for states to follow in developing plans to address greenhouse gas emissions from existing fossil fuel-fired electric generating units. Specifically, the EPA is proposing state-specific rate-based goals for CO2 emissions from the power sector, as well as guidelines for states to follow in developing plans to achieve the state-specific goals. On August 3, 2015, the EPA finalized the Clean Power Plan Rule to cut carbon pollution from existing power plants, which became effective on December 22, 2015. Numerous petitions challenging the Clean Power Plan Rule have been consolidated into one case, West Virginia v. EPA. While the litigation is still ongoing at the circuit court level, a mid-litigation application to the Supreme Court resulted in a stay of the Clean Power Plan Rule. On September 27, 2016, an en banc panel of the U.S. Court of Appeals for the D.C. Circuit heard oral arguments in the case and a decision is expected in early 2017.

Internationally, the Kyoto Protocol, which set binding emission targets for developed countries (which was not ratified by the United States) was nominally extended past its expiration date of December 2012 with a requirement for a new legal construct to be put into place by 2015. In December 2015, the United Nations Climate Change Conference was held and an agreement was reached between the countries participating in the conference, including the United States, to limit global warming to less than 2 degrees Celsius (3.6° Fahrenheit) compared to pre-industrial levels. This agreement, known as the Paris Agreement, calls for zero net anthropogenic greenhouse gas emission to be reached during the second half of the 21st century. Each party is to prepare a plan on its contributions to reach this goal; each plan is to be filed in a publicly available registry. In addition, in November 2014, President Obama announced that the United States would seek to cut net greenhouse gas emissions 26-28 percent below 2005 levels by 2025 in return for China's commitment to seek to peak emissions around 2030, with concurrent increases in renewable energy. The United States participation in the Paris Agreement is unclear with the change in Administration in January 2017.

Additionally, coalbed methane must be expelled from our underground coal mines for mining safety reasons and is vented into the atmosphere when the coal is mined. Coalbed methane has a greater GHG effect than carbon dioxide. If regulation of GHG emissions does not exempt the release of coalbed methane, we may have to further reduce our methane emissions, pay higher taxes, incur costs to purchase credits that permit us to continue operations as they now exist at our underground coal mines or perhaps curtail coal production.

Apart from governmental regulation, investment banks based both domestically and internationally have announced that they have adopted climate change guidelines for lenders. The guidelines require the evaluation of carbon risks in the financing of electric power generation plants which may make it more difficult for utilities to obtain financing for coal-fired plants.

Adoption of comprehensive legislation or regulation focusing on GHG emission reductions for the United States or other countries where we sell coal (including by adopting plans to implement the Paris Agreement), or the inability of utilities to obtain financing in connection with coal-fired plants, may make it more costly to operate fossil fuel fired (especially coal-fired) electric power generation plants and make fossil fuels less attractive for electric utility power plants in the future. Depending on the nature of the regulation or legislation, natural gas-fueled power generation could become more economically attractive than coal-fueled power generation, substantially increasing the demand for natural gas. Apart from actual regulation, uncertainty over the extent of regulation of GHG emissions may inhibit utilities from investing in the building of new coal-fired plants to replace older plants or investing in the upgrading of existing coal-fired plants. Any reduction in the amount of coal or possibly natural gas consumed by domestic electric power generators as a result of actual or potential regulation of greenhouse gas emissions could decrease demand for our fossil fuels, thereby reducing our revenues and materially and adversely affecting our business and results of operations. We or our customers may also have to invest in carbon dioxide capture and storage technologies in order to burn coal or natural gas and comply with future GHG emission standards.

In addition, there have also been efforts in recent years affecting the investment community, including investment advisers, sovereign wealth funds, public pension funds, universities and other groups, promoting the divestment of fossil fuel equities and also pressuring lenders to limit funding to companies engaged in the extraction of fossil fuel reserves. The impact of such efforts may adversely affect the demand for and price of securities issued by us, and impact our access to the capital and financial markets.

Environmental regulations introduce uncertainty that could adversely impact the market for natural gas and coal with potential short and long-term liabilities.

The Federal Endangered Species Act (ESA) and similar state laws protect species endangered or threatened with extinction. Protection of endangered and threatened species may cause us to modify gas well pad siting or pipeline right of ways, mining plans, or develop and implement species-specific protection and enhancement plans to avoid or minimize impacts to endangered species or their habitats. A number of species indigenous to the areas where we operate are protected under the ESA. On January 14, 2016, the US Fish and Wildlife Service (USFWS) finalized a rule exempting certain types of “take” of northern long-eared bats from the requirement to obtain an incidental take permit, pursuant to Section 4(d) of the Endangered Species Act. This listing could lead to significant timing and critical path hurdles, ultimately limiting the ability to clear timber for construction activities in our operations area.

Other species that are being considered for listing as endangered under the ESA are the Big Sandy Crayfish, the Guyandotte River Crayfish and the Rusty Patched Bumble Bee, all of which if listed have the potential to interfere with the proposed layout of our mine plans and surface facilities, including natural gas well pads, compressor stations and pipelines, as well as the manner in which we operate our mines and facilities. USFWS has stated that the primary threats to crayfishes throughout their respective ranges are land-disturbing activities that increase erosion and sedimentation, which degrades the stream habitat required by both species. Identified sources of ongoing erosion and sedimentation that occur throughout the ranges of the species include active surface coal mining, commercial forestry, unpaved roads, natural gas and oil development, and road construction. This has the potential to disrupt future mining and natural gas activities in Appalachia.

On December 19, 2016, the federal Office of Surface Mining released final regulations to the Stream Protection Rule, which is intended to prevent or minimize impacts to surface water and groundwater from coal mining. The rule will require companies to restore streams and return mined areas to the uses they were capable of supporting prior to mining activities, and replant these areas with native trees and vegetation, unless that would conflict with the implemented land use. The rule requires the testing and monitoring of the condition of streams that might be affected by mining - before, during and after their operations - to provide baseline data that ensures operators can detect and correct problems that could arise, and restore mined areas to their previous condition. The final SPR requires the restoration of the physical form, hydrologic function, and ecological function of the segment of a perennial or intermittent stream that a permittee mines through. Additionally, it requires that the post-mining surface configuration of the reclaimed mine site include a drainage pattern, including ephemeral streams, similar to the pre-mining drainage pattern, with exceptions for stability, topographical changes, fish and wildlife habitat, etc. The rule also requires the establishment of a 100-foot-wide streamside vegetative corridor of native species (including riparian species, when appropriate) along each bank of any restored or permanently-diverted perennial, intermittent, or ephemeral stream. This rulemaking is highly anticipated to be subject to Legislative and Executive branch actions to overturn or significantly modify the rule.

CONSOL Energy utilizes pipelines extensively for its natural gas, water and coal businesses. Mitigation permits from the Army Corps of Engineers (ACOE) are typically required for certain impacts these pipelines cause to streams and wetlands. On April 21, 2014 the EPA published a proposed rule called “Definition of ‘Waters of the United States’ (WoUS) Under the Clean Water Act.” The proposal would expand the scope of the CWA to include previously non-jurisdictional streams, wetlands, and waters, making these areas jurisdictional inter-coastal waters of the U.S. In February 2015 the EPA and ACOE issued a memorandum of understanding to withdraw the WoUS Interpretive Rule. The EPA published the latest version of the WoUS rule (the Clean Water Rule) on June 29, 2015, which was to become effective on August 28, 2015. However, on August 27, 2015, the District Court of North Dakota blocked implementation of the rule in 13 states. On October 9, 2015, the Court of Appeals for the Sixth Circuit blocked implementation of the rule nationwide. The U.S. Supreme Court will now decide which court has jurisdiction - federal appeals court or district courts. A decision is expected sometime in mid 2017.

Management and regulation of point source discharges covered under the National Pollutant Discharge Eliminations System (NPDES) of the CWA have undergone recent changes and proposed changes at both the state and federal level that have the potential to affect the long-term treatment and discharge of water from coal mines. States are required by the CWA to conduct a comprehensive review of the state water quality standards every three years (the "Triennial Review"). WV has issued an emergency rule effective June 21, 2014 and proposed amendments under 47 CSR 2 with specific requirements for the discharge of aluminum and selenium that pose potential impacts on the coal industry. Ohio (OH) is currently reviewing the current 401 and 404 permitting program to propose new amendments.

In April 2015, the EPA proposed a CWA regulation (Effluent Limitations Guidelines and Standards for the Oil and Gas Extraction Point Source Category) establishing pretreatment standards that would prohibit the indirect discharge of wastewater from onshore unconventional oil and gas extraction facilities to publicly owned treatment works (POTWs). While discharges

34

to POTWs are not currently utilized, unconventional oil and gas extraction wastewater can be generated in large quantities. It is unclear how the newly proposed rule could affect future water use and disposal practices.

State regulations for horizontal well drilling and well site construction have been proposed and finalized. In September, 2015, PA published a final rulemaking on the revisions to the Environmental Protection Performance Standards at Oil and Gas Well Sites (Chapters 78 and 78a). These rules are the subject of pending litigation. OH passed Horizontal Well Site Construction Rules which will become effective in July 2015. OH is also in the process of reviewing and possibly adopting additional horizontal development rules.

Our natural gas and coal mining operations are subject to operating risks, including our reliance upon third-party contractors, which could increase our operating expenses and decrease our production levels which could adversely affect our results of operations. Our natural gas and coal operations are also subject to hazards and any losses or liabilities we suffer from hazards which occur in our operations may not be fully covered by our insurance policies.

Our exploration for and production of natural gas involves numerous operating risks. The cost of drilling, completing and operating our shale gas wells, shallow oil and gas wells and coalbed methane (CBM) wells is often uncertain, and a number of factors can delay or prevent drilling operations, decrease production and/or increase the cost of our natural gas operations at particular sites for varying lengths of time thereby adversely affecting our operating results. The operating risks that may have a significant impact on our natural gas operations include:

• unexpected drilling conditions;

• title problems;

• pressure or irregularities in geologic formations;

• equipment failures or repairs;

• fires, explosions or other accidents;

• adverse weather conditions;

• reductions in natural gas prices;

• security breaches or terroristic acts;

• pipeline ruptures;

• lack of adequate capacity for treatment or disposal of waste water generated in drilling, completion and production operations;

• environmental contamination from surface spillage of fluids used in well drilling, completion or operation including fracturing fluids used in hydraulic fracturing of wells, or other contamination of groundwater or the environment resulting from our use of such fluids; and

• unavailability or high cost of drilling rigs, other field services and equipment.

Our coal mining operations are underground mines. Underground mining and related processing activities present inherent risks of injury to persons and damage to property and equipment. Our mines are subject to a number of operating risks that could disrupt operations, decrease production and increase the cost of mining at particular mines for varying lengths of time thereby adversely affecting our operating results. In addition, if an operating risk occurs in our mining operations, we may not be able to produce sufficient amounts of coal to deliver under our multi-year coal contracts. Our inability to satisfy contractual obligations could result in our customers initiating claims against us or canceling their contracts. The operating risks that may have a significant impact on our coal operations include:

• variations in thickness of the layer, or seam, of coal;

• adverse geological conditions, including amounts of rock and other natural materials intruding into the coal that could affect the stability of the roof and the side walls of the mine - for example, unit costs were negatively impacted in 2016 due to adverse geological conditions at Enlow Fork mine, primarily related to sandstone intrusions, which resulted in reduced coal production at that mine;

• environmental hazards;

• equipment failures or unexpected maintenance problems;

• fires or explosions, including as a result of methane, coal, coal dust or other explosive materials and/or other accidents;

• inclement or hazardous weather conditions and natural disasters or other force majeure events;

• seismic activities, ground failures, rock bursts or structural cave-ins or slides;

• delays in moving our longwall equipment;

• railroad derailments;

• security breaches or terroristic acts; and

• other hazards that could also result in personal injury and loss of life, pollution and suspension of operations.

35

The occurrence of any of these risks at our natural gas or coal mining operations could adversely affect our ability to conduct natural gas or coal mining operations or result in substantial loss to us as a result of claims for:

• personal injury or loss of life;

• damage to and destruction of property, natural resources and equipment, including our coal properties and our coal production or transportation facilities;

• pollution and other environmental damage to our properties or the properties of others;

• potential legal liability and monetary losses;

• regulatory investigations and penalties;

• suspension of our operations; and

• repair and remediation costs.

In addition, the occurrence of any of these events in our coal mining operations which prevents our delivery of coal to a customer and which is not excusable as a force majeure event under our coal sales agreement, could result in economic penalties, suspension or cancellation of shipments or ultimately termination of the coal sales agreement.

Although we maintain insurance for a number of risks and hazards, we may not be insured or fully insured against the losses or liabilities that could arise from a significant accident in our natural gas and coal operations. We may elect not to obtain insurance for any or all of these risks if we believe that the cost of available insurance is excessive relative to the risks presented. In addition, pollution and environmental risks generally are not fully insurable. Moreover, a significant mine accident could potentially cause a mine shutdown. The occurrence of an event that is not fully covered by insurance could have a material adverse effect on our business, financial condition, results of operations and cash flows.

We also rely upon third-party contractors to provide key services to our natural gas operations. We contract with third-parties for well services, related equipment, and qualified experienced field personnel to drill wells and conduct field operations. The demand for these field services in the natural gas and oil industry can fluctuate significantly. Higher oil and natural gas prices generally stimulate increased demand causing periodic shortages. These shortages may lead to escalating prices for drilling equipment, crews and associated supplies, equipment and services. Shortages may lead to poor service and inefficient drilling operations and increase the possibility of accidents due to the hiring of inexperienced personnel and overuse of equipment by contractors. In addition, the costs and delivery times of equipment and supplies are substantially greater in periods of peak demand. Accordingly, we cannot assure that we will be able to obtain necessary drilling equipment and supplies in a timely manner or on satisfactory terms, and we may experience shortages of, or increases in the costs of, drilling equipment, crews and associated supplies, equipment and field services in the future. We utilize third-party contractors to provide land acquisition and related services to support our land operational needs for both natural gas and coal segments. We also use third-party contractors to provide construction and specialized services to our coal mining operations. A decrease in the availability of field services or equipment and supplies, an increase in the prices charged for field services, equipment and supplies, or the failure of third-party contractors to provide quality field services to us, could decrease our natural gas and coal production, increase our costs of natural gas and coal production, and decrease our anticipated profitability.

We attempt to mitigate the risks involved with increased natural gas industrial activity by entering into “take or pay” contracts with well service providers which commit them to provide field services to us at specified levels and commit us to pay for field services at specified levels even if we do not use those services. However, these contracts expose us to economic risk during a downturn in demand or during periods of oversupply. For example, in 2016 due to the oversupply of gas in our markets, we made payments under these contracts of approximately $33 million for field services that we did not use. Having to pay for services we do not use decreases our cash flow and increases our costs of production.

We may not be able to obtain equipment, parts and raw materials in a timely manner, in sufficient quantities or at reasonable costs to support our coal mining and natural gas operations.

Coal mining consumes large quantities of commodities including steel, copper, rubber products and liquid fuels and requires the use of capital equipment. Some commodities, such as steel, are needed to comply with roof control plans required by regulation. The prices we pay for commodities and capital equipment are strongly impacted by the global market. A rapid or significant increase in the costs of commodities or capital equipment we use in our operations could impact our mining operations costs because we may have a limited ability to negotiate lower prices, and, in some cases, may not have a ready substitute.

We use equipment in our coal mining and transportation operations such as continuous mining units, conveyors, shuttle cars, rail cars, locomotives, roof bolters, shearers and shields. We procure this equipment from a concentrated group of suppliers, and obtaining this equipment often involves long lead times. Occasionally, demand for such equipment by mining companies

36

can be high and some types of equipment may be in short supply. Delays in receiving or shortages of this equipment, as well as the raw materials used in the manufacturing of supplies and mining equipment, which, in some cases, do not have ready substitutes, or the cancellation of our supply contracts under which we obtain equipment and other consumables, could limit our ability to obtain these supplies or equipment. In addition, if any of our suppliers experiences an adverse event, or decides to no longer do business with us, we may be unable to obtain sufficient equipment and raw materials in a timely manner or at a reasonable price to allow us to meet our production goals and our revenues may be adversely impacted. We use considerable quantities of steel in the mining process. If the price of steel or other materials increases substantially or if the value of the U.S. dollar declines relative to foreign currencies with respect to certain imported supplies or other products, our operating expenses could increase. Any of the foregoing events could materially and adversely impact our business, financial condition, results of operations or cash flows.

Additionally, we rely on a supply of drilling rigs, equipment, personnel and services in our naturual gas operations. The demand for this equipment and for qualified and experienced field personnel to drill wells and conduct field operations, geologists, geophysicists, engineers, and other professionals in the oil and natural gas industry can fluctuate significantly, often in correlation with natural gas and oil prices, causing periodic shortages. Historically, there have been shortages of drilling and workover rigs, pipe and other equipment as demand for rigs and equipment has increased along with the number of wells being drilled. We cannot predict whether these conditions will exist in the future and, if so, what their timing and duration will be. Such shortages could delay or cause us to incur significant expenditures that are not provided for in our capital budget, which events could materially and adversely impact our business, financial condition, results of operations, or cash flows.

For drilling and mining operations, CONSOL Energy must obtain, maintain, and renew governmental permits and approvals which if we cannot obtain in a timely manner would reduce our production, cash flow and results of operations.

State and local authorities regulate various aspects of natural gas drilling and production activities, including the drilling of wells (through permit and bonding requirements), the spacing of wells, the unitization or pooling of natural gas properties, environmental matters, safety standards, market sharing and well site restoration. Delays or denials of natural gas permits could reduce our production, cash flows and results of operations.

Our coal production is dependent on our ability to obtain various federal and state permits and approvals to mine our coal reserves. The permitting rules, and the interpretations of these rules, are complex, change frequently and are often subject to discretionary interpretations by regulators. The EPA also has the authority to veto permits issued by the U.S. Army Corps of Engineers under the Clean Water Act’s Section 404 program that prohibits the discharge of dredged or fill material into regulated waters without a permit. In addition, the public, including non-governmental organizations and individuals, have certain statutory rights to comment upon and otherwise impact the permitting process, including through court intervention. The pace with which the government issues permits needed for new operations for  on-going operations  to  continue  mining continues to pose significant negative effects. Further, in 2011 the EPA revoked an ACOE-issued Section 404 permit to a coal mining operator. Following the U.S. Supreme Court’s refusal in March 2012 to hear an appeal from the D.C. Circuit Court’s ruling upholding the EPA’s power to revoke a permit, in September 2014 the U.S. Court of Appeals upheld the EPA’s action to revoke the permit. In addition, in July 2014 the D.C Circuit reversed a lower court’s decision and affirmed the EPA’s authority to adopt the Enhanced Coordination Process governing coordination with the ACOE in the processing of CWA permits. The Court also rejected challenges to EPA’s 2012 “Final Guidance” document regarding appropriate permit conditions, namely those affecting acceptable conductivity limits (e.g., acceptable ionic strength to support aquatic life). However, the Court left it up to the states on whether to adopt the guideline recommendations when issuing final NPDES permits. This decision has left coal mining permits in some degree of uncertainty whether the EPA will concur with a state’s draft permit conditions should they not contain specified limits regarding conductivity, further increasing operational uncertainty and costs.

The pace with which the government issues permits needed for new operations and for on-going operations to continue coal mining has negatively impacted expected production. These delays or denials of coal mining permits could reduce our production, cash flows and results of operations.

In addition, in 2005, the Pennsylvania Department of Environmental Protection (“PADEP”) issued a technical guidance document that imposes standards in the material mining permits that we hold relating to our Pennsylvania Operations, including costly stream mitigation and monitoring requirements and alterations to our longwall mining plans.

Existing and future government laws, regulations and other legal requirements relating to protection of the environment, and others that govern our business may increase our costs of doing business for coal and may restrict our coal operations.

37

We are subject to laws, regulations and other legal requirements enacted or adopted by federal, state and local authorities, as well as foreign authorities relating to protection of the environment. These include those legal requirements that govern discharges of substances into the air and water, the management and disposal of hazardous substances and wastes, the cleanup of contaminated sites, groundwater quality and availability, threatened and endangered plant and wildlife protection, reclamation and restoration of mining or drilling properties after mining or drilling is completed, the installation of various safety equipment in our mines, remediation of impacts of surface subsidence from underground mining, and work practices related to employee health and safety. Complying with these requirements, including the terms of our permits, has had, and will continue to have, a significant effect on our costs of operations and competitive position.

In addition, there is the possibility that we could incur substantial costs as a result of violations under environmental laws. Any additional laws, regulations and other legal requirements enacted or adopted by federal, state and local authorities, as well as foreign authorities or new interpretations of existing legal requirements by regulatory bodies relating to the protection of the environment could further affect our costs of operations and competitive position. The Clean Water Act is being used by opponents of mountain top removal mining as a means to challenge permits and bring citizen suits to make coal mining more expensive. At CONSOL Energy’s subsidiary Fola Coal Company, LLC, six citizen suits have been filed challenging water discharge permits. Two of those suits were settled in 2014, and at least two are potentially affected by recent settlements by another mining operator in a similar case.

Existing and future government laws, regulations and other legal requirements relating to protection of the environment, and others that govern our business may increase our costs of doing business for natural gas, and may restrict our natural gas operations.

Regulations applicable to the natural gas industry are under constant review for amendment or expansion at the federal and state level. Any future changes may affect, among other things, the pricing or marketing of natural gas production. For example, hydraulic fracturing is an important and common practice that is used to stimulate production of hydrocarbons, particularly natural gas, from tight formations such as the Marcellus Shale. The process involves the injection of water, sand and chemicals under pressure into formations to fracture the surrounding rock and stimulate production. The process is typically regulated by state oil and gas commissions. Hydraulic fracturing is currently exempt from regulation under the federal Safe Drinking Water Act, except for hydraulic fracturing using diesel fuel. The disposal of produced water, drilling fluids and other wastes in underground injection disposal wells is regulated by the EPA under the federal Safe Drinking Water Act or by the states under counterpart state laws and regulations. The imposition of new environmental initiatives and regulations could include restrictions on our ability to conduct hydraulic fracturing operations or to dispose of waste resulting from such operations. The EPA commenced a study of the potential environmental impacts of hydraulic fracturing activities and the final report was issued in December 2016.

We are required to obtain pre-approval for construction or modification of certain facilities, to meet stringent air permit requirements, or to use specific equipment, technologies or best management practices to control emissions. On August 16, 2012, the U.S. Environmental Protection Agency (EPA) published final revisions to the New Source Performance Standards (NSPS) to regulate emissions of volatile organic compounds (VOCs) and sulfur dioxide (SO2) from various oil and gas exploration, production, processing and transportation facilities. Additionally, revisions were made to the National Emission Standards for Hazardous Air Pollutants (NESHAPS) to further regulate emissions from the oil and natural gas production sector and the transmission and storage of natural gas. Section 111 of the CAA authorized the EPA to develop technology based standards which apply to specific categories of stationary sources. In September 2009, the EPA finalized the Mandatory Reporting of Greenhouse Gas Rule. The current version of this rule requires annual reporting of emissions from natural gas wells, coal mines and associated facilities.

The EPA has proposed to amend the Petroleum and Natural Gas Systems source category (Subpart W) of the Greenhouse Gas Reporting Program (GHGRP). This proposed rule would add reporting of greenhouse gas emissions from certain gathering and boosting systems, completions and workovers of oil wells using hydraulic fracturing, and blowdowns of natural gas transmission pipelines. The rule would also require operators to utilize new monitoring equipment in order to comply with Subpart W. On September 18, 2015, the EPA proposed updates to the New Source Performance Standards (NSPS) that would create new standards for the regulation of methane and VOC emission sources. The proposed rule includes requirements for new fugitive emission and leak detection testing and reporting requirements. On September 18, 2015, the EPA proposed the Source Determination Rule which would clarify the use of the term “adjacent” in determining Title V air permitting requirements as they apply to the oil and natural gas industry for major sources of air emissions. Other federal agencies are also examining hydraulic fracturing, including the U.S. Department of Energy (DOE), the U.S. Government Accountability Office and the Department of the Interior. Also, some states have adopted, and other states are considering adopting, regulations that could restrict or impose additional requirements relating to hydraulic fracturing in certain circumstances. If hydraulic fracturing is

38

regulated at the federal, state or local level, our fracturing activities could become subject to additional permit requirements or operational restrictions and also to associated permitting delays and potential increases in costs.

Further, air emissions that stem from hydraulic fracturing and completions processes, as well as from midstream activities such as the gathering and transmission of natural gas, are regulated by federal and state rules. However, interpretations of those rules, as well as additional changes to the regulations, could negatively impact our ability to meet our stated production objectives for the company. For example, source aggregation of air emissions to determine whether, under the Clean Air Act a source comprises a single stationary source and is therefore a major source of air pollution, and thereby subject to the applicability of Nonattainment Prevention of Significant Deterioration and Title V permitting requirements, has and continues to be debated by the EPA, state regulatory agencies and the courts. Recently, the Pennsylvania Environmental Hearing Board determined the emission sources of an upstream subsidiary and a midstream subsidiary of a company were aggregated as a single source, given the dynamic nature of the issue. Federal and state activities, as well as court decisions could impact the development and transmission of plans of CONSOL Energy, our joint venture partners, and gathering systems being installed and operated by CONE Midstream Partners, LP.

Additionally, some states have begun to adopt more stringent regulation and oversight of natural gas gathering lines than is currently required by federal standards. Pennsylvania, under Act 127, authorized the Public Utility Commission (PUC) oversight of Class I gathering lines, as well as requiring standards and fees associated with Class II and Class III pipelines. The state of Ohio also moved to regulate natural gas gathering lines in a similar manner pursuant to Ohio Senate Bill 315 (SB315). SB315 expanded the Ohio PUC's authority over rural natural gas gathering lines. These changes in interpretation and regulation affect CONSOL Energy's midstream activities, requiring changes in reporting, as well as increased costs.

Further, some state and local governments in the Marcellus Shale region in Pennsylvania and New York have considered or imposed a temporary moratorium on drilling operations using hydraulic fracturing until further study of the potential for environmental and human health impacts by the EPA or the relevant agencies are completed. Further, states could elect to prohibit hydraulic fracturing altogether, as Governor Andrew Cuomo of the State of New York announced in December 2014 with regard to fracturing activities in New York. No assurance can be given as to whether or not similar measures might be considered or implemented in jurisdictions in which our gas properties are located. If new laws or regulations that significantly restrict or otherwise impact hydraulic fracturing are passed by Congress or adopted in states in which we operate, such legal requirements could make it more difficult or costly for us to perform hydraulic fracturing activities and thereby could affect the determination of whether a well is commercially viable. New laws or regulations could also cause delays or interruptions or terminations of operations, the extent of which cannot be predicted, and could reduce the amount of oil and natural gas that we ultimately are able to produce in commercially paying quantities from our natural gas properties, all of which could have a materially adverse effect on our results of operations and financial condition.

On April 8, 2016, The U.S. Department of Transportation (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA) published in the Federal Register a Notice of Proposed Rule Making (NPRM) that would significantly modify existing regulations related to reporting, impact, design, construction, maintenance, operations and integrity management of natural gas transmission and gathering pipelines. The proposed rule addresses four congressional mandates and six recommendations by the National Transportation Safety Board to broaden the scope of safety coverage by adding new assessment and repair criteria for gas transmission pipelines, and by expanding these protocols to include pipelines not formerly regulated by the federal standards. This includes extending regulatory requirements to transmission and gathering pipelines of 8 inches and greater in rural class 1 areas. Compliance with the rule, as proposed, may prove challenging and costly for operators of older pipelines due to the difficulty of locating historic records. Compliance could involve significant upfront costs and service disruptions. The relatively short 2-year timeframe for compliance for gathering pipelines could also be difficult to meet. Costs of compliance with the proposed rule could potentially affect shippers on pipelines as well as operators themselves, as the Federal Energy Regulatory Commission has allowed many interstate transmission pipelines to pass along costs attributable to safety measures directly to shippers. If implemented as proposed, CONSOL Energy (CONE & CNX Coal Resources) will be affected by this rulemaking. However, long-term costs for compliance will be dependent on the finalized version of the rule.

Our shale gas drilling and production operations require both adequate sources of water to use in the fracturing process, as well as the ability to dispose of water and other wastes after hydraulic fracturing. Our CBM gas drilling and production operations also require the removal and disposal of water from the coal seams from which we produce gas. If we cannot find adequate sources of water for our use or are unable to dispose of the water we use or remove it from the strata at a reasonable cost and within applicable environmental rules, our ability to produce natural gas economically and in commercial quantities could be impaired.

39

As part of our drilling and production in shale formations, we use hydraulic fracturing processes. Thus, we need access to adequate sources of water to use in our shale operations. Further, we must remove and dispose of the portion of the water that we use to fracture our shale gas wells that flows back to the well-bore, as well as drilling fluids and other wastes associated with the exploration, development or production of natural gas. In addition, in our CBM drilling and production, coal seams frequently contain water that must be removed and disposed of in order for the natural gas to detach from the coal and flow to the well bore. Our inability to locate sufficient amounts of water with respect to our shale operations, or the inability to dispose of or recycle water and other wastes used in our shale and our CBM operations, could adversely impact our operations.

Our mines are subject to stringent federal and state safety regulations that increase our cost of doing business at active operations and may place restrictions on our methods of operation. In addition, government inspectors under certain circumstances, have the ability to order our operations to be shutdown based on safety considerations.

The Federal Coal Mine Safety and Health Act and Mine Improvement and New Emergency Response Act impose stringent health and safety standards on mining operations. Regulations that have been adopted are comprehensive and affect numerous aspects of mining operations, including training of mine personnel, mining procedures, the equipment used in mine emergency procedures and other matters. Most states in which we operate have programs for mine safety and health regulation and enforcement. The various requirements mandated by law or regulation can place restrictions on our methods of operations, and potentially lead to fees and civil penalties for the violation of such requirements, creating a significant effect on operating costs and productivity. In addition, government inspectors under certain circumstances, have the ability to order our operation to be shutdown based on safety considerations. If an incident were to occur at one of our coal mines, it could be shut down for an extended period of time and our reputation with our customers could be materially damaged.

Our operations may impact the environment or cause exposure to hazardous substances, and our properties may have environmental contamination, which could result in liabilities to us.

Our operations currently use hazardous materials and generate limited quantities of hazardous wastes from time to time. Drainage flowing from or caused by mining activities can be acidic with elevated levels of dissolved metals, a condition referred to as “acid mine drainage.” We could become subject to claims for toxic torts, natural resource damages and other damages, as well as for the investigation and clean-up of soil, surface water, groundwater, and other media. Such claims may arise, for example, out of conditions at sites that we currently own or operate, as well as at sites that we previously owned or operated, or may acquire. Our liability for such claims may be joint and several, so that we may be held responsible for more than our share of the contamination or other damages, or for the entire share.

We maintain coal refuse areas and slurry impoundments at a number of our coal mining complexes. Such areas and impoundments are subject to extensive regulation. Structural failure of a slurry impoundment or coal refuse area could result in extensive damage to the environment and natural resources, such as bodies of water that the coal slurry reaches, as well as liability for related personal injuries and property damages, and injuries to wildlife. Some of our impoundments overlie mined out areas, which can pose a heightened risk of failure and of damages arising out of failure. If one of our impoundments were to fail, we could be subject to claims for the resulting environmental contamination and associated liability, as well as for fines and penalties. Our coal refuse areas and slurry impoundments are designed, constructed, and inspected by our company and by regulatory authorities according to stringent environmental and safety standards.

In West Virginia there are areas where drainage from coal mining operations contains concentrations of selenium that without treatment would result in violations of state water quality standards that are set to protect fish and other aquatic life. We have several operations with selenium discharges. We and other coal companies have worked to expeditiously develop cost effective means to remove selenium from mine water.

These and other similar unforeseen impacts that our operations may have on the environment, as well as exposures to hazardous substances or wastes associated with our operations, could result in costs and liabilities that could adversely affect us. An example of this is Naturally Occurring Radioactive Material (NORM) or Technologically-Enhanced, Naturally Occurring Radioactive Material (TENORM). NORM or TENORM is produced when activities such as deep drilling concentrate or expose radioactive materials that occur naturally in ores, soils, water, or other natural materials. State and federal agencies are examining the possibility for worker exposure or associated environmental hazards due to processing and disposal of wastes containing NORM or TENORM, as well as silica dust associated with natural gas well completions activities.

We have reclamation, mine closing and gas well plugging obligations. If the assumptions underlying our accruals are inaccurate, we could be required to expend greater amounts than anticipated.

40

The Surface Mining Control and Reclamation Act establishes operational, reclamation and closure standards for all our coal mining operations. Also, state laws require us to plug natural gas wells and reclaim well sites after the useful life of our natural gas wells has ended. We accrue for the costs of current mine disturbance, gas well plugging and of final mine closure, including the cost of treating mine water discharge where necessary. Estimates of our total reclamation, mine-closing liabilities and gas well plugging, which are based upon permit requirements and our experience, were approximately $474 million at December 31, 2016. The amounts recorded are dependent upon a number of variables, including the estimated future closure costs, estimated proved reserves, assumptions involving profit margins, inflation rates, and the assumed credit-adjusted risk-free interest rates. If these accruals are insufficient or our liability in a particular year is greater than currently anticipated, our future operating results could be adversely affected.

Most states where we operate require us to post bonds for the full cost of coal mine reclamation (full cost bonding).

West Virginia is not a full cost bonding state. West Virginia has an alternative bond system (ABS) for coal mine reclamation which consists of (i) individual site bonds posted by the permittee that are less than the full estimated reclamation cost plus (ii) a bond pool (Special Reclamation Fund) funded by a per ton fee on coal mined in the State which is used to supplement the site specific bonds if needed in the event of bond forfeiture. In an effort to settle a citizen suit filed in 2012 before the U.S. District Court in West Virginia related to the Special Reclamation Fund being underfunded the WV legislature authorized an increase in the per ton fee levied on coal production to make up the shortfall. The Special Reclamation Fund became fully funded in June of 2016. There remains the possibility that WV may move to full cost bonding in the future which could cause individual mining companies and/or surety companies to exceed bonding capacity and would result in the need to post cash bonds or letters of credit which would reduce operating capital.

Pennsylvania is expanding its full cost bonding program to cover all coal mine bonding, further increasing the amount of surety bonds we must seek in order to permit its mining activities.

We have been able to post surety bonds with the states to secure our reclamation obligations. If our creditworthiness declines, states may seek to require us to post letters of credit or cash collateral to secure those obligations, or we may be unable to obtain surety bonds, in which case we would be required to post letters of credit. Additionally, the sureties that post bonds on our behalf may require us to post security in order to secure the obligations underlying these bonds. Posting letters of credit in place of surety bonds or posting security to support these surety bonds would have an adverse effect on our liquidity.

We face uncertainties in estimating our economically recoverable natural gas and coal reserves, and inaccuracies in our estimates could result in lower than expected revenues, higher than expected costs and decreased profitability.

Natural gas and coal reserves are economically recoverable when the price at which they are expected to be sold exceeds their expected cost of production and selling.

Natural gas reserves require subjective estimates of underground accumulations of natural gas assumptions concerning natural gas prices, production levels, reserve estimates and operating and development costs. As a result, estimated quantities of proved natural gas reserves and projections of future production rates and the timing of development expenditures may be incorrect. For example, a significant amount of our proved undeveloped reserves extensions and discoveries during the last three years were due to the addition of wells on our Marcellus Shale acreage more than one offset location away from existing production with reliable technology, which may be more susceptible to positive and negative changes in reserve estimates than our proved developed reserves. Over time, material changes to reserve estimates may be made, taking into account the results of actual drilling, testing and production. Also, we make certain assumptions regarding natural gas prices, production levels, and operating and development costs that may prove incorrect. Any significant variance from these assumptions to actual figures could greatly affect our estimates of our natural gas reserves, the economically recoverable quantities of natural gas attributable to any particular group of properties, the classifications of natural gas reserves based on risk of recovery and estimates of the future net cash flows. Numerous changes over time to the assumptions on which our reserve estimates are based, as described above, often result in the actual quantities of natural gas we ultimately recover being different from reserve estimates. The present value of future net cash flows from our proved reserves is not necessarily the same as the current market value of our estimated natural gas reserves. We base the estimated discounted future net cash flows from our proved natural gas reserves on historical average prices and costs. However, actual future net cash flows from our natural gas properties also will be affected by factors such as:

• geological conditions;

• changes in governmental regulations and taxation;

• the amount and timing of actual production;

• assumptions governing future prices;

41

• future operating costs; and

• capital costs of drilling, completion and gathering assets.

The timing of both our production and our incurrence of expenses in connection with the development and production of natural gas properties will affect the timing of actual future net cash flows from proved reserves and thus their actual present value. In addition, the 10% discount factor we use when calculating discounted future net cash flows may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the oil and natural gas industry in general. If natural gas prices decline by $0.10 per Mcf, then the pre-tax present value using a 10% discount rate of our proved natural gas reserves as of December 31, 2016 would decrease from $1.6 billion to $1.4 billion.

We base our coal reserve information on geologic data, coal ownership information and current and proposed mine plans. These estimates are periodically updated to reflect past coal production, new drilling information and other geologic or mining data. Similar to natural gas reserves, there are uncertainties inherent in estimating quantities and values of economically recoverable coal reserves, including many factors beyond our control. As a result, estimates of economically recoverable coal reserves are by their nature uncertain. Information about our reserves consists of estimates based on engineering, economic and geological data assembled and analyzed by our staff. Some of the factors and assumptions which impact economically recoverable coal reserve estimates include:

• geologic conditions;

• historical production from the area compared with production from other producing areas;

• the assumed effects of regulations and taxes by governmental agencies;

• our ability to obtain, maintain and renew all required permits;

• future improvements in mining technology;

• assumptions governing future prices; and

• future operating costs, including the cost of materials and capital expenditures.

In addition, we hold substantial coal reserves in areas containing Marcellus Shale and other shales. These areas are currently the subject of substantial exploration for oil and natural gas, particularly by horizontal drilling. If a natural gas well is in the path of our mining for coal, we may not be able to mine through the well unless we purchase it. Although in the past we have purchased vertical wells, the cost of purchasing a producing horizontal well could be substantially greater. Horizontal wells with multiple laterals extending from the well pad may access larger natural gas reserves than a vertical well which could result in higher costs. In future years, the cost associated with purchasing natural gas wells which are in the path of our coal mining may make mining through those wells uneconomical thereby effectively causing a loss of significant portions of our coal reserves.

Each of the factors which impacts reserve estimation may in fact vary considerably from the assumptions used in estimating the reserves. For these reasons, estimates of natural gas and coal reserves may vary substantially. Actual production, revenues and expenditures with respect to our coal and natural gas reserves will likely vary from estimates, and these variances may be material. As a result, our estimates may not accurately reflect our actual coal and natural gas reserves

Defects may exist in our chain of title for our natural gas estate or undeveloped coal reserves where we have not done a thorough chain of title examination of our natural gas estate or undeveloped coal reserves. We may incur additional costs and delays to produce natural gas or mine coal because we have to acquire additional property rights to perfect our title to natural gas or coal rights. If we fail to acquire additional property rights to perfect our title to natural gas or coal rights, we may have to reduce our estimated reserves.

Substantial amounts of acreage in which we believe we control natural gas rights are in areas where we have not yet done a thorough chain of title examination of the natural gas estate. A number of our natural gas properties were acquired primarily for the coal rights with the focus on the coal estate title, and, in many cases were acquired years ago. In addition, we have acquired natural gas rights in substantial acreage from third parties who had not performed thorough chain of title work on their natural gas properties. Our practice, and we believe industry practice, is not to perform a thorough title examination on natural gas properties until shortly before the commencement of drilling activities at which time we seek to acquire any additional rights needed to perfect our ownership of the natural gas estate for development and production purposes. When we perform a thorough chain of title examination, we may discover material defects in our title which would require us to acquire additional property rights. We may incur substantial costs to acquire these additional property rights. In addition, the acquisition of the necessary rights may not be feasible in some cases. Our discovering of title defects which we are unable to cure may adversely impact our ability to develop those properties and we may have to reduce our estimated natural gas reserves including our proved undeveloped reserves.

42

Some states (West Virginia and Virginia) permit us to produce coalbed methane gas without perfected ownership under an administrative process known as “pooling,” which requires us to give notice to all potential claimants and pay royalties into escrow until the undetermined rights are resolved. As a result, we may have to pay royalties to produce coalbed methane gas on acreage that we control and these costs may be material. Further, the pooling process is time-consuming and may delay our drilling program in the affected areas.

Likewise, title to most of our owned or leased properties and mineral rights is not usually verified until we make a commitment to mine a property, which may not occur until after we have obtained necessary permits and completed exploration of the property. In some cases, we rely on title information or representations and warranties provided by our lessors or grantor's. Our right to mine certain of our reserves has in the past been, and may again in the future be, adversely affected if defects in title, boundaries or other rights necessary for mining exist or if a lease expires. Any challenge to our title or leasehold interests could delay the mining of the property and could ultimately result in the loss of some or all of our interest in the property. From time to time we also may be in default with respect to leases for properties on which we have mining operations. In such events, we may have to close down or significantly alter the sequence of such mining operations which may adversely affect our future coal production and future revenues. If we mine on property that we do not own or lease, we could incur liability for such mining and be subject to regulatory sanction and penalties.

In order to obtain, maintain or renew leases or mining contracts to conduct our mining operations on property where these defects exist, we may in the future have to incur unanticipated costs. In addition, we may not be able to successfully negotiate new leases or mining contracts for properties containing additional reserves, or maintain our leasehold interests in properties where we have not commenced mining operations during the term of the lease. As a result, our results of operations, business and financial condition may be materially adversely affected.

CONSOL Energy and its subsidiaries are subject to various legal proceedings, which may have an adverse effect on our business.

We are party to a number of legal proceedings in the normal course of business activities. Defending these actions, especially purported class actions, can be costly, and can distract management. For example, we are a defendant in three pending purported class action lawsuits dealing with claimants’ alleged entitlements to, and accounting for, natural gas royalties. There is the potential that the costs of defending litigation in an individual matter or the aggregation of many matters could have an adverse effect on our cash flows, results of operations or financial position. See Note 22- Commitments and Contingent Liabilities in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for further discussion of pending legal proceedings.

We have obligations for long-term employee benefits for which we accrue based upon assumptions which, if inaccurate, could result in our being required to expense greater amounts than anticipated.

We provide various long-term employee benefits to inactive and retired employees. We accrue amounts for these obligations. At December 31, 2016, the current and non-current portions of these obligations included:

• postretirement medical and life insurance ($700 million);

• coal workers' black lung benefits ($119 million);

• salaried retirement benefits ($115 million); and

• workers' compensation ($80 million).

However, if our assumptions are inaccurate, we could be required to expend greater amounts than anticipated. Salary retirement benefits are funded in accordance with Employer Retirement Income Security Act of 1974 (ERISA) regulations. The other obligations are unfunded. In addition, the federal government and several states in which we operate consider changes in workers' compensation and black lung laws from time to time. Such changes, if enacted, could increase our benefit expense and our collateral requirements. We post letters of credit and surety bonds as collateral for some of these liabilities that reduce our profitability and liquidity.

We do not control the timing of divestitures that we plan to engage in and they may not provide anticipated benefits. Additionally, we may be unable to acquire additional properties in the future and any acquired properties may not provide the anticipated benefits.

Our business and financing plans include divesting certain assets over time. However, we do not control the timing of divestitures and delays in entering into divestitures may reduce the benefits from them. Additionally, if assets are held jointly with another party, we may not be permitted to dispose of these assets without the consent of our joint venture partner. Also, there can

43

be no assurance that the assets we divest will produce anticipated proceeds. In addition, the terms of divestitures may cause a substantial portion of the benefits we anticipate receiving from them to be subject to future matters that we do not control.

In the future we may make acquisitions of businesses that complement or expand our current business. No assurance can be given that we will be able to identify suitable acquisition opportunities, negotiate acceptable terms, obtain financing for acquisitions on acceptable terms or successfully acquire the identified targets. The success of any completed acquisition will depend on our ability to effectively integrate the acquired business into our existing operations. The process of integrating acquired businesses may involve unforeseen difficulties and may require a disproportionate amount of our managerial and financial resources. Our failure to make acquisitions in the future and successfully integrate the acquired businesses and assets into our existing operations could have a material adverse effect on our financial condition and results of operations

We may operate a material portion of our business with one or more joint venture partners. A joint venture may restrict our operational and corporate flexibility; actions taken by a joint venture partner may materially impact our financial position and results of operations; and we may not realize the benefits we expect to realize from a joint venture.

As is common in the industry we may operate one or more of our properties with a joint venture partner. These joint ventures could require us to share operational and other control with our joint venture partner, such that we may no longer have the flexibility to control completely the development of these properties. If we do not timely meet our financial commitments in a joint venture, our rights to participate in such joint venture will be adversely affected and the other party to the joint venture may have a right to acquire a share of our interest in such joint venture proportionate to, and in satisfaction of, our unmet financial obligations. If our joint venture partner is unable or fails to pay its portion of development costs, our costs of operations could be increased and it could result loss of rights to develop the properties held by that joint venture. We could also incur liability as a result of actions taken by our joint venture partner. Disputes between us and our joint venture partner may result in litigation or arbitration that would increase our expenses, delay or terminate projects and distract our officers and directors from focusing their time and effort on our business.

The provisions of our debt agreements and the risks associated with our debt could adversely affect our business, financial condition, liquidity and results of operations.

As of December 31, 2016, our total long-term indebtedness was approximately $2.80 billion of which approximately $1.85 billion was under our 5.875% senior unsecured notes due 2022 plus $5 million of unamortized bond premium, $500 million was under our 8.000% senior unsecured notes due 2023 less $6 million of unamortized bond discount, $74 million was under our 8.250% senior unsecured notes due 2020, $21 million was under our 6.375% senior unsecured notes due 2021, $103 million was under our Maryland Economic Development Corporation Port Facilities Refunding Revenue Bonds (MEDCO) 5.75% revenue bonds due September 2025, $49 million of capitalized leases due through 2021, $5 million of miscellaneous debt and $201 million in outstanding borrowings under the revolver for CNXC of which we are not a guarantor. The degree to which we are leveraged could have important consequences, including, but not limited to:

• increasing our vulnerability to general adverse economic and industry conditions;

• requiring us to dedicate a substantial portion of our cash flow from operations to the payment of interest and principal due under our outstanding debt, which will limit our ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions, development of our gas and coal reserves or other general corporate requirements;

• limiting our flexibility in planning for, or reacting to, changes in our business and in the coal and natural gas industries;

• placing us at a competitive disadvantage compared to our competitors with lower leverage and better access to capital resources; and

• limiting our ability to implement our business strategy.

Our senior secured credit facility and the indentures governing our 5.875% and 8.000% senior unsecured notes limit the incurrence of additional indebtedness unless specified tests or exceptions are met. In addition, our senior secured credit agreement and the indentures governing our 5.875% and 8.000% senior unsecured notes subject us to financial and/or other restrictive covenants. Under our senior secured credit agreement, we must comply with certain financial covenants on a quarterly basis including a minimum interest coverage ratio, and a minimum current ratio, as defined therein. Our senior secured credit agreement and the indentures governing our 5.875% and 8.000% senior unsecured notes impose a number of restrictions upon us, such as restrictions on granting liens on our assets, making investments, paying dividends, stock repurchases, selling assets and engaging in acquisitions. Failure by us to comply with these covenants could result in an event of default that, if not cured or waived, could have a material adverse effect on us.

44

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to sell assets, seek additional capital or seek to restructure or refinance our indebtedness. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. In the absence of such operating results and resources, we could face substantial liquidity problems and might be required to sell material assets or operations to attempt to meet our debt service and other obligations. Our senior secured credit agreement and the indentures governing our 5.875% and 8.000% senior unsecured notes restrict our ability to sell assets and use the proceeds from the sales. We may not be able to consummate those sales or to obtain the proceeds which we could realize from them and these proceeds may not be adequate to meet any debt service obligations then due.

Unless we replace our natural gas reserves, our natural gas reserves and production will decline, which would adversely affect our business, financial condition, results of operations, liquidity and cash flows.

Producing natural gas reservoirs generally are characterized by declining production rates that vary depending upon reservoir characteristics and other factors. Because total estimated proved reserves include our proved undeveloped reserves at December 31, 2016, production is expected to decline even if those proved undeveloped reserves are developed and the wells produce as expected. The rate of decline will change if production from our existing wells declines in a different manner than we have estimated and can change under other circumstances. Thus, our future natural gas reserves and production and, therefore, our cash flow and income are highly dependent on our success in efficiently developing and exploiting our current reserves and economically finding or acquiring additional recoverable reserves. We may not be able to develop, find or acquire additional reserves to replace our current and future production at acceptable costs.

Our lenders use the loan value of our proved natural gas reserves to determine the borrowing base under our $2.0 billion senior secured credit facility. Our borrowing base could decrease for a variety of reasons including lower natural gas prices, declines in natural gas proved reserves, and lending requirements or regulations. Significant reductions in our borrowing base below $2.0 billion could have a material adverse effect on our results of operations, financial condition and liquidity.

Our ability to borrow and have letters of credit issued under our $2.0 billion senior secured credit facility is generally limited to a borrowing base. Our borrowing base is determined by the required number of lenders in good faith calculating a loan value of the Company’s proved natural gas reserves. The borrowing base under our senior secured credit facility is currently $2.0 billion. Our borrowing base is redetermined by the lenders twice per year, and the next scheduled borrowing base redetermination is expected to occur in May 2017. The various matters which we describe in other risk factors that can decrease our proved natural gas reserves including lower natural gas prices, operating difficulties, and failure to replace our proved reserves could decrease our borrowing base. Please read: “Risk Factors - We face uncertainties in estimating our economically recoverable natural gas and coal reserves, and inaccuracies in our estimates could result in lower than expected revenues, higher than expected costs and decreased profitability” and - “Unless we replace our natural gas reserves, our natural gas reserves and production will decline, which would adversely affect our business, financial condition, results of operations and cash flows.” Our borrowing base could also decrease as a result of new lending requirements or regulations or the issuance of new indebtedness. If our borrowing base declined significantly below $2.0 billion, we may be unable to implement our drilling and development plans, make acquisitions or otherwise carry out our business plan which could have a material adverse effect on our financial condition and results of operation. We also could be required to repay any indebtedness in excess of the redetermined borrowing base. We could face substantial liquidity problems, might not be able to access the equity or debt capital markets and might be required to sell material assets or operations to attempt to meet our debt service and other obligations. We may not be able to consummate those sales or to obtain the proceeds which we could realize from them and these proceeds may not be adequate to meet any debt service obligations then due.

Our hedging activities may prevent us from benefiting from price increases and may expose us to other risks.

To manage our exposure to fluctuations in the price of natural gas, we enter into hedging arrangements with respect to a portion of our expected production. As of January 17, 2017, we had hedges on approximately 311.3 Bcf of our 2017 natural gas production, 220.6 Bcf of our 2018 natural gas production, 161.7 Bcf of our 2019 natural gas production, 85.0 Bcf of our 2020 and natural gas production and 6.8 Bcf of our 2021 and natural gas production. To the extent that we engage in hedging activities, we may be prevented from realizing the near-term benefits of price increases above the levels of the hedges. If we choose not to engage in, or reduce our use of hedging arrangements in the future, we may be more adversely affected by changes in natural gas prices than our competitors who engage in hedging arrangements to a greater extent than we do.

45

In addition, such transactions may expose us to the risk of financial loss in certain circumstances, including instances in which:

• our production is less than expected;

• the counterparties to our contracts fail to perform the contracts;

• the creditworthiness of our counterparties or their guarantors is substantially impaired;

• counterparties have credit limits that may constrain our ability to hedge additional volumes.

Changes in federal or state income tax laws, particularly in the area of percentage depletion and intangible drilling costs, could cause our financial position and profitability to deteriorate.

The passage of legislation or any other similar changes in U.S. federal income tax law could eliminate or postpone certain tax deductions that are currently available with respect to natural gas, oil or coal exploration and development. Any such change could negatively affect our financial condition and results of operations.

Additionally, legislation has been proposed in Ohio and Pennsylvania to introduce a new severance tax on the oil and gas industry. The proposed rates have varied from 2.5 - 7.5 percent and would represent a significant increased financial burden on the economics of the wells we drill in these states.

Strategic determinations, including the allocation of capital and other resources to strategic opportunities, are challenging, and our failure to appropriately allocate capital and resources among our strategic opportunities may adversely affect our financial condition. Additionally, our development and exploration projects require substantial capital expenditures and if we fail to obtain required capital or financing on satisfactory terms, our natural gas reserves may decline.

Our future growth prospects are dependent upon our ability to identify optimal strategies for our business. In developing our business plan, we consider allocating capital and other resources to various aspects of our businesses including well development (primarily drilling), reserve acquisitions, exploratory activity, coal development, corporate items and other alternatives. We also consider our likely sources of capital, including cash generated from operations and borrowings under our credit facilities. Notwithstanding the determinations made in the development of our business plan, business opportunities not previously identified periodically come to our attention, including possible acquisitions and dispositions. If we fail to identify optimal business strategies, or fail to optimize our capital investment and capital raising opportunities and the use of our other resources in furtherance of our business strategies, our financial condition and future growth may be adversely affected. Moreover, economic or other circumstances may change from those contemplated by our business plan, and our failure to recognize or respond to those changes may limit our ability to achieve our objectives.

As part of our strategic determinations, we expect to continue to make substantial capital expenditures in the development and acquisition of natural gas reserves. We cannot assure you that we will have sufficient cash from operations, borrowing capacity under our credit facilities or the ability to raise additional funds in the capital markets. If cash flow generated by our operations or available borrowings under our credit facilities are not sufficient to meet our capital requirements, or we are unable to obtain additional financing, we could be required to curtail the pace of the development of our natural gas properties, which in turn could lead to a decline in our reserves and production, and could adversely affect our business, financial condition and results of operations.

Any failure by Murray Energy to satisfy the liabilities it assumed from us, as well as to perform its obligations under various agreements whose performance by Murray Energy we guaranteed, or under various agreements with us, could materially increase our liabilities and materially adversely affect our results of operations, financial position and cash flows.

In 2013, Murray Energy and its subsidiaries (Murray Energy) acquired approximately $2.4 billion of liabilities which had been reflected on our books. The consolidated balance sheet liabilities at the time of sale were comprised of approximately $2.1 billion of OPEB and other liabilities. In addition to these assumed liabilities, (i) Murray Energy acquired our obligations to make payments per hour worked to the multi-employer defined benefit pension plan for United Mine Workers of America (1974 Pension Plan), (ii) we guaranteed performance by Murray Energy under various West Virginia and Pennsylvania operational surety bonds and workers compensation obligations, under various equipment leases and to reclaim an impoundment site, (iii) we leased or subleased various mining equipment to Murray Energy, and (iv) we guaranteed performance by Murray Energy of certain coal supply agreements that Murray Energy acquired in the transaction. At the time of sale, if the hourly payment obligations acquired by Murray Energy to the 1974 Pension Plan were to be capitalized, they would have had a present value of approximately

46

$941 million, assuming a discount rate of 4.02%.We believe our maximum estimated exposure under our Murray Energy guarantees as of December 31, 2016 was approximately $74 million. The leases and subleases we entered into with Murray Energy relate to approximately $106 million of equipment. Murray Energy is primarily liable for the acquired retiree medical liabilities under the Coal Industry Retiree Health Benefits Act of 1992, which we call the Coal Act, but CONSOL Energy remains secondarily liable. At the time of the sale, the Coal Act liabilities Murray Energy acquired were approximately $307 million and it was estimated that the servicing cost for these liabilities would be approximately $26 million for 2017 and would decline thereafter since the beneficiaries principally are miners who retired prior to 1994. On November 12, 2013, in connection with the transaction, Moody’s assigned Murray Energy a family credit rating of B3 (speculative and subject to high credit risk) and its secured second lien notes due 2021 a rating of Caa1 (poor standing and subject to very high credit risk). Since the transaction, Murray Energy’s credit ratings have been downgraded by Moody’s. In November, 2016, Moody’s upgraded Murray Energy to a family credit rating of Caa2 and the rating on its secured second lien notes to Caa3 with a stable outlook. Any failure by Murray Energy to satisfy these assumed liabilities or perform under these agreements could result in substantial claims against us by third-parties and if, successful, could materially adversely affect our results of operations, financial position and cash flows. In addition, we regularly evaluate the likelihood of default by Murray Energy under the guarantees we have provided. The results of the evaluation may materially impact our results of operations. If Murray Energy defaults under the obligations we guaranteed, our cash flows may also be materially impacted.

Terrorist attacks or a cyber incident could result in information theft, data corruption, operational disruption and/or financial loss.

We have become increasingly dependent upon digital technologies, including information systems, infrastructure and cloud applications and services, to operate our businesses, to process and record financial and operating data, communicate with our employees and business partners, analyze seismic and drilling information, estimate quantities of natural gas reserves and coal reserves, as well as other activities related to our businesses. Strategic targets, such as energy-related assets, may be at greater risk of future physical attacks by terrorists or cyber attacks than other targets in the United States. Deliberate attacks on our assets, or security breaches in our systems or infrastructure, or the systems or infrastructure of third-parties, or the cloud could lead to corruption or loss of our proprietary data and potentially sensitive data, delays in production or delivery, difficulty in completing and settling transactions, challenges in maintaining our books and records, environmental damage, communication interruptions, other operational disruptions and third -party liability. Our insurance may not protect us against such occurrences. Consequently, it is possible that any of these occurrences, or a combination of them, could have a material adverse effect on our business, financial condition and results of operations. Further, as cyber incidents continue to evolve, we may be required to expend additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerability to cyber incidents.

A substantial majority of sales of thermal coal are from three mines at one location in Pennsylvania, making us vulnerable to risks associated with operating in a single geographic area.

The substantial majority of our sales of thermal coal, as well as our thermal coal reserves, are from our Bailey Mine, Enlow Fork Mine and HarveyMine located in Greene County, Pennsylvania. In addition, we also rely upon one coal processing plant and rail load facility, located in Enon, Pennsylvania for shipping coal from all of these mines. Any disruption in the functioning of this coal processing plant and rail load-out facility such as the structural failure at the above ground conveyor system which occurred in 2012 or in transportation in this area could significantly reduce our sales of thermal coal and adversely affect our results of operation and financial condition.

Certain provisions in our multi-year coal sales contracts may provide limited protection during adverse economic conditions, may result in economic penalties to us or permit the customer to terminate the contract.

Price adjustment, “price reopener” and other similar provisions in our multi-year coal sales contracts may reduce the protection from coal price volatility traditionally provided by coal supply contracts. Price reopener provisions are present in several of our multi-year coal sales contracts. These price reopener provisions may automatically set a new price based on prevailing market price or, in some instances, require the parties to agree on a new price, sometimes within a specified range of prices. In a limited number of agreements, failure of the parties to agree on a price under a price reopener provision can lead to termination of the contract. Any adjustment or renegotiations leading to a significantly lower contract price could adversely affect our profitability.

Most of our coal sales agreements contain provisions requiring us to deliver coal within certain ranges for specific coal quality characteristics such as heat content, sulfur, ash, moisture, volatile matter, grindability, ash fusion temperature and size consist. Failure to meet these conditions could result in penalties or rejection of the coal at the election of the customer. Our coal

47

sales contracts also typically contain force majeure provisions allowing for the suspension of performance by either party for the duration of specified events. Force majeure events include, but are not limited to, floods, earthquakes, storms, fire, faults in the coal seam or other geologic conditions, other natural catastrophes, wars, terrorist acts, civil disturbances or disobedience, strikes, railroad transportation delays caused by a force majeure event and actions or restraints by court order and governmental authority or arbitration award. Depending on the language of the contract, some contracts may terminate upon continuance of an event of force majeure that extends for a period greater than three to twelve months and some contracts may obligate us to perform notwithstanding what would typically be a force majeur event.

The majority our common units in CNX Coal Resources LP and CONE Midstream Partners LP are subordinated to other common units and we may not receive distributions from CNX Coal Resources LP or CONE Midstream Partners LP.

As of December 31, 2016, we hold 11.6 million subordinated units (representing a 42.7 percent limited partnership interest) in CNX Coal Resources LP, which we call CNXC. The balance of our CNXC limited partnership interests are held in the form of preferred and common units. Subordinated units are not entitled to any distribution from CNXC unless CNXC makes a minimum quarterly distribution of $0.4678 per Class A Preferred Unit and $0.5125 per common unit. CNXC made minimum distributions per subordinated unit equal to the distribution per common unit for five of the six quarters since CNXC’s IPO.  CNXC did not met the requirement for a subordinated unit distribution with respect to fiscal quarter ended June 30, 2016 and we did not receive a distribution per subordinated unit, however, CNXC was able to make minimum distributions per subordinated unit equal to the distribution per common unit with respect to the fiscal quarter ended September 30, 2016 and declared minimum distributions per subordinated unit equal to the distribution per common unit with respect to the fiscal quarter ended December 31, 2016. We cannot assure you that CNXC will continue to be able to make or will make the required minimum quarterly distribution on its preferred and common units or that we will receive any future distributions on our subordinated units. Failure by CNXC to make distributions to us on our subordinated units could adversely affect our liquidity. 

We hold 14.6 million subordinated units (representing 23.0 percent limited partnership interest) in CONE Midstream Partners LP, which we call CONE. The balance of CONE's limited partnership interests are held either by NOBLE Energy or in the form of common units. Subordinated units are not entitled to any distribution from CONE unless CONE makes a minimum quarterly distribution on its common units of $0.2125 per unit. CONE has met this requirement with respect to each of its fiscal quarters and we received a distribution per subordinated unit equal to the distribution per common unit. However, we cannot assure you that CONE will continue to be able to make or will make the required minimum quarterly distribution on its common units or that we will receive any future distributions on our subordinated units. Failure by CONE to make distributions to us on our subordinated units could adversely affect our liquidity.

Cumulative Total Shareholder Return Among CONSOL Energy Inc., Peer Group and S&P 500 Stock Index

The above information is being furnished pursuant to Regulation S-K, Item 201 (e) (Performance Graph).

The declaration and payment of dividends by CONSOL Energy is subject to the discretion of CONSOL Energy’s Board of Directors, and no assurance can be given that CONSOL Energy will pay dividends in the future. CONSOL Energy suspended its quarterly dividend following the sale of the Buchanan Mine on March 31, 2016 to further reflect the Company's increased emphasis on growth. CONSOL Energy’s Board of Directors determines whether dividends will be paid quarterly. The determination to pay dividends will depend upon, among other things, general business conditions, CONSOL Energy’s financial results, contractual and legal restrictions regarding the payment of dividends by CONSOL Energy, planned investments by CONSOL Energy and such other factors as the Board of Directors deems relevant. The Company's credit facility limits CONSOL Energy's ability to pay dividends in excess of an annual rate of $0.50 per share when the Company's leverage ratio exceeds 3.50 to 1.00 and subject to an aggregate amount up to the then cumulative credit calculation. The total leverage ratio was 4.53 to 1.00 and the cumulative credit was approximately $781 million at December 31, 2016. The calculation of this ratio excludes CNXC. The credit facility does not permit dividend payments in the event of default. The indentures to the 2022 and 2023 notes limit dividends to $0.50 per share annually unless several conditions are met. These conditions include no defaults, ability to incur additional debt and other payment limitations under the indentures. There were no defaults in the year ended December 31, 2016.

See Part III, Item 12. “Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters” for information relating to CONSOL Energy's equity compensation plans.

CONSOL Energy consists of two principal business divisions: Exploration and Production (E&P) and Pennsylvania (PA) Mining Operations. The E&P division includes four reportable segments: Marcellus, Utica, Coalbed Methane (CBM) and Other Gas.

The E&P division had a loss before income tax of $379 million for the year ended December 31, 2016, compared to a loss before income tax of $679 million for the year ended December 31, 2015. Included in the 2016 net loss before income tax was an unrealized loss on commodity derivative instruments of $386 million. Included in the 2015 net loss before income tax was a loss of $829 million primarily related to the impairment of the carrying value of CONSOL Energy's shallow oil and natural gas assets due to depressed NYMEX forward strip prices (see Note 9 - Property, Plant and Equipment of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information). The impairment loss was partially off-set by an unrealized gain on commodity derivative instruments of $197 million.

The following table presents a breakout of net liquid and natural gas sales information to assist in the understanding of the Company’s natural gas production and sales portfolio.

The E&P division natural gas, NGLs, and oil sales were $794 million for the year ended December 31, 2016, compared to $729 million for the year ended December 31, 2015. The increase was primarily due to the 20.0% increase in total E&P sales volumes, offset in part by the 11.5% decrease in the average gas sales price per Mcf without the impact of derivative instruments from the table above. The decrease in average sales price was the result of the overall decrease in general market prices.

The E&P division sales volumes, average sales price (including the effects of derivatives instruments), and average costs for all active E&P operations were as follows: 

	For the Years Ended December 31,
	2016		2015		Variance			Percent Change
E&P Sales Volumes (Bcfe)	394.4		328.7		65.7			20.0	%
Average Sales Price (per Mcfe)	$	2.63	$	2.81	$	(0.18	)	(6.4	)%
Average Costs (per Mcfe)	2.32		2.62		(0.30		)	(11.5	)%
Average Margin	$	0.31	$	0.19	$	0.12		63.2	%

Changes in the average costs per Mcfe were primarily related to the following items:

• The improvement in unit costs is primarily due to the continuing shift towards lower cost Marcellus and dry Utica Shale production, ongoing cost reduction efforts and the 20.0% increase in total volumes sold in the period-to-period comparison. Marcellus production made up 53.9% of E&P sales volumes in the year ended December 31, 2016, compared to 52.4% in the year ended December 31, 2015. Utica production made up 23.0% of E&P sales volumes in the year ended December 31, 2016, compared to 17.1% in the year ended December 31, 2015.

• Lifting costs per unit decreased in the period-to-period comparison primarily due to the increase in overall sales volumes, as well as a decrease in well site maintenance costs, employee related costs and costs related to wells operated by the Company's joint venture partners. The decrease was offset, in part, by an increase in total dollars relating to higher salt water disposal costs.

• Transportation, gathering and compression expense decreased on a per unit basis in the period-to-period comparison due to the overall increase in E&P sales volumes, the shift towards dry Utica Shale production which has lower gathering costs since there are no associated processing fees and a decrease in pipeline and facility maintenance expense. The decrease in unit costs was partially offset by an increase in total dollars related to an increase in utilized firm transportation costs, increased processing fees associated with NGLs, and an increase in CONE gathering expense directly related to the increase in Marcellus production. See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information.

The PA Mining Operations division had earnings before income tax of $131 million for the year ended December 31, 2016, compared to earnings before income tax of $405 million for the year ended December 31, 2015.

Sales tons, average sales price and average cost of goods sold per ton for the PA Mining Operations division were as follows:

	For the Years Ended December 31,
	2016		2015		Variance			Percent Change
Company Produced PA Mining Operations Tons sold (in millions)	24.6		22.9		1.7			7.4	%
Average Sales Price per ton sold	$	43.31	$	56.36	$	(13.05	)	(23.2	)%
Average Costs of Goods Sold per ton sold	34.35		41.78		(7.43		)	(17.8	)%
Average Margin	$	8.96	$	14.58	$	(5.62	)	(38.5	)%

The lower average sales price per ton sold in the 2016 period was primarily the result of the overall decline in the domestic and global thermal coal markets, particularly in the first half of 2016. This decline was primarily related to higher customer inventories and lower gas prices after persistently mild 2015 weather. This was off-set by an increase in overall tons sold reflecting the improvement in both domestic and international coal demand throughout the second half of 2016.

The PA Mining Operations division priced 5.4 million tons on the export market for the year ended December 31, 2016, compared to 5.5 million tons for the year ended December 31, 2015. All other tons were sold on the domestic market.

55

Changes in the average cost of goods sold per ton were primarily driven by the idling of one longwall at the PA Mining Operations complex for approximately 90 days, a reduction of staffing levels and a realignment of employee benefits in the current year. All of the above steps resulted in more consistent operating schedules, reduced labor costs, and improved productivity.

The Other division includes other business activities not assigned to the E&P or PA Mining Operations division and income taxes. The Other division had a net loss of $287 million for the year ended December 31, 2016, compared to a net loss of $77 million for the year ended December 31, 2015.

Selling, general and administrative (SG&A) costs are allocated to the PA Mining Operations division based upon a shared service agreement that CONSOL Energy entered into with CNX Coal Resources LP (CNXC) upon execution of the CNXC initial public offering (IPO). The shared service agreement calls for CONSOL Energy to provide certain selling, general and administrative services that are paid for monthly, based on an agreed upon fixed fee that is reset at least annually. See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information. The remaining SG&A costs are allocated between the E&P and Other divisions based primarily on a percentage of total revenue and a percentage of total projected capital expenditures.

SG&A costs are excluded from the E&P and PA Mining Operations unit costs above. SG&A costs were $153 million for the year ended December 31, 2016, compared to $158 million for the year ended December 31, 2015. SG&A costs decreased due to the following items:

	For the Years Ended December 31,
(in millions)	2016		2015		Variance			Percent Change
Short-Term Incentive Compensation	$	29	$	40	$	(11	)	(27.5	)%

Other	10		—		10			100.0	%
Total Company Selling, General and Administrative Expense	$	153	$	158	$	(5	)	(3.2	)%

• The decrease in Short-Term Incentive Compensation was a result of lower payouts in the current year.

• Employee Wages and Related Expenses decreased$8 million primarily due to the Company reorganization that occurred in the second half of 2015 and the first quarter of 2016, which resulted in an overall decrease in employees.

• Stock-Based Compensation increased$6 million in the period-to-period comparison primarily due to additional non-cash amortization expense recorded in the current period for the Performance Share Unit (PSU) program.

• Other increased$10 million in the period-to-period comparison primarily due to a 401(k) discretionary contribution in the current period.

Total Company long-term liabilities, such as Other Post-Employment Benefits (OPEB), the salary retirement plan, workers' compensation, Coal Workers' Pneumoconiosis (CWP), and long-term disability are actuarially calculated for the Company as a whole. In general, the expenses are then allocated to the segments based upon criteria specific to each liability. Total CONSOL Energy continuing operations expense related to actuarial liabilities was $74 million for the year ended December 31, 2016, compared to income of $162 million for the year ended December 31, 2015. The increase of $236 million is primarily due to modifications made to the OPEB and Pension plans in May 2015. See Note 14—Pension and Other Postretirement Benefit Plans and Note 15—Coal Workers' Pneumoconiosis (CWP) and Workers' Compensation in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional details.

The Marcellus segment had natural gas, NGLs and oil sales of $415 million for the year ended December 31, 2016 compared to $379 million for the year ended December 31, 2015. The $36 million increase is primarily due to a 23.3% increase in total Marcellus sales volumes, partially offset by a 10.5%decrease in the average gas sales price in the period-to-period comparison. The increase in total sales volumes is primarily due to additional wells coming on-line in the current year, as well as the termination of the Marcellus Joint Venture that CONSOL Energy had with Noble Energy (See Note 9 - Property, Plant and Equipment in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional details). The joint venture termination was effective October 1st, 2016 and resulted in additional production for the fourth quarter of 2016, as well as the applicable sales and production costs.

The decrease in the total average Marcellus sales price was primarily the result of the $0.22 per Mcf decrease in gas market prices, along with a $0.03 per Mcf decrease in the uplift from NGLs and condensate sales volumes, when excluding the impact of hedging. These decreases were offset, in part, by a $0.12 per Mcf increase in the gain on commodity derivative instruments resulting from the Company's hedging program. The increase in the gain was due to an increase in volumes hedged and lower market prices. The notional amounts associated with these financial hedges represented approximately 160.8 Bcf of the Company's produced Marcellus gas sales volumes for the year ended December 31, 2016 at an average gain of $0.92 per Mcf. For the year ended December 31, 2015, these financial hedges represented approximately 90.3 Bcf at an average gain of $1.09 per Mcf.

Total exploration and production costs for the Marcellus segment were $490 million for the year ended December 31, 2016 compared to $424 million for the year ended December 31, 2015. The increase in total dollars and decrease in unit costs for the Marcellus segment were due to the following items:

•Marcellus lease operating expense was $34 million for the year ended December 31, 2016 compared to $44 million for the year ended December 31, 2015. The decrease in total dollars was primarily due to a reduction in employee related costs, well tending costs and repairs and maintenance expense in the current period. The reduction in employee related costs was primarily due to the company reorganization that occurred in the second half of 2015 and the first quarter of 2016. The decrease in unit costs

58

was primarily due to the 23.3%increase in total Marcellus sales volumes, along with the decreased total dollars described above. The decreases were offset, in part, by an increase in salt water disposal costs in the period-to-period comparison.

•Marcellus production, ad valorem, and other fees were $17 million for the year ended December 31, 2016 compared to $18 million for the year ended December 31, 2015. The decrease in total dollars was primarily due to the decrease in total average Marcellus sales price, offset, in part, by the increase in total Marcellus sales volumes.

•Marcellus transportation, gathering and compression costs were $228 million for the year ended December 31, 2016 compared to $200 million for the year ended December 31, 2015. The $28 million increase in total dollars was primarily related to an increase in the CONE gathering fee due to the increase in total Marcellus sales volumes (See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information), an increase in processing fees associated with natural gas liquids primarily due to the 23.7%increase in NGLs sales volumes, and an increase in utilized firm transportation expense. The decrease in unit costs was due to the increase in total Marcellus sales volumes, offset, in part, by the increase in total dollars.

•Depreciation, depletion and amortization costs attributable to the Marcellus segment were $211 million for the year ended December 31, 2016 compared to $162 million for the year ended December 31, 2015 driven primarily by the overall increase in production. These amounts included depletion on a unit of production basis of $0.98 per Mcf and $0.92 per Mcf, respectively. The remaining depreciation, depletion and amortization costs were either recorded on a straight-line basis or related to gas well closing.

UTICA SEGMENT

The Utica segment had earnings before income tax of $28 million for the year ended December 31, 2016 compared to a loss before income tax of $19 million for the year ended December 31, 2015.

*NGLs and Condensate are converted to Mcfe at the rate of one barrel equals six mcf based upon the approximate relative energy content of oil and natural gas, which is not indicative of the relationship of oil, NGLs, condensate, and natural gas prices.

The Utica segment had natural gas, NGLs and oil sales of $163 million for the year ended December 31, 2016 compared to $93 million for the year ended December 31, 2015. The $70 million increase was primarily due to the 61.6%increase in total

59

Utica sales volumes. The 34.6 Bcfe increase in total Utica sales volumes was due to additional wells coming on-line, primarily in dry Utica areas, in the current period.

The increase in the total average Utica sales price was primarily due to a $0.24 per Mcf increase in the gain on commodity derivative instruments in the current period, as well as a $0.16 per Mcf increase in the uplift from NGLs and condensate sales volumes. The increase in the hedging gain was due to an increase in the volumes hedged that were designated as Utica volumes. Financial hedges represented approximately 31.6 Bcf of the Company's produced Utica gas sales volumes for the year ended December 31, 2016 at an average gain of $0.93 per Mcf. For the year ended December 31, 2015, these financial hedges represented approximately 5.9 Bcf at an average gain of $1.08 per Mcf.

Total exploration and production costs for the Utica segment were $164 million for the year ended December 31, 2016 compared to $118 million for the year ended December 31, 2015. The increase in total dollars and decrease in unit costs for the Utica segment are due to the following items:

•Utica lease operating expense remained flat at $22 million for each of the years ended December 31, 2016 and December 31, 2015. The decrease in unit costs was primarily due to the 61.6%increase in total Utica sales volumes.

•Utica production, ad valorem, and other fees were $5 million for the year ended December 31, 2016 compared to $2 million for the year ended December 31, 2015. The increase in total dollars was primarily due to the 61.6%increase in total Utica sales volumes. The increase in unit costs was also due to a credit received from a joint venture partner in the 2015 period, related to an over-billing of ad valorem taxes.

•Utica transportation, gathering and compression costs were $51 million for the year ended December 31, 2016 compared to $35 million for the year ended December 31, 2015. The $16 million increase in total dollars was primarily related to increased gathering and processing fees associated with the increased Utica NGLs and gas sales volumes. The decrease in unit costs was due to the increase in total Utica sales volumes, predominantly dry Utica, which was offset, in part, by the increase in total dollars.

•Depreciation, depletion and amortization costs attributable to the Utica segment were $86 million for the year ended December 31, 2016 compared to $59 million for the year ended December 31, 2015 driven primarily by the overall increase in production. These amounts included depletion on a unit of production basis of $0.93 per Mcf and $1.05 per Mcf, respectively. The remaining depreciation, depletion and amortization costs were either recorded on a straight-line basis or related to gas well closing.

COALBED METHANE (CBM) SEGMENT

The CBM segment had earnings before income tax of $38 million for the year ended December 31, 2016 compared to earnings before income tax of $60 million for the year ended December 31, 2015.

Average Margin for CBM (per Mcf)	$	0.55	$	0.80	$	(0.25	)	(31.3	)%

The CBM segment had natural gas sales of $175 million for the year ended December 31, 2016 compared to $202 million for the year ended December 31, 2015. The $27 milliondecrease was primarily due to a 6.3%decrease in the average gas sales

60

price, as well as a 7.9%decrease in CBM gas sales volumes. The decrease in CBM sales volumes was primarily due to normal well declines and less drilling activity.

The total average CBM sales price decreased $0.31 per Mcf due primarily to a $0.17 per Mcf decrease in gas market prices, as well as a $0.14 per Mcf decrease in the gain on commodity derivative instruments resulting from the Company's hedging program. The notional amounts associated with these financial hedges represented approximately 55.0 Bcf of the Company's produced CBM sales volumes for the year ended December 31, 2016 at an average gain of $0.95 per Mcf. For the year ended December 31, 2015, these financial hedges represented approximately 57.5 Bcf at an average gain of $1.17 per Mcf.

Total exploration and production costs for the CBM segment were $189 million for the year ended December 31, 2016 compared to $209 million for the year ended December 31, 2015. The decrease in total dollars and decrease in unit costs for the CBM segment were due to the following items:

•CBM lease operating expense was $25 million for the year ended December 31, 2016 compared to $33 million for the year ended December 31, 2015. The decrease in total dollars was primarily related to a decrease in contractual services related to well tending, a decrease in repairs and maintenance expense, a decrease in employee related costs, and a decrease in salt water disposal costs. The decrease in unit costs was due to the decrease in total dollars, partially offset by the decrease in CBM gas sales volumes.

•CBM production, ad valorem, and other fees were $6 million for the year ended December 31, 2016 compared to $7 million for the year ended December 31, 2015. The $1 million decrease was due to a decrease in severance tax expense resulting from the decrease in both gas sales volumes and average sales price. Unit costs were positively impacted by the decrease in total average CBM sales price which was offset, in part, by the decrease in CBM gas sales volumes.

•CBM transportation, gathering and compression costs were $72 million for the year ended December 31, 2016 compared to $85 million for the year ended December 31, 2015. The $13 million decrease was primarily related to a decrease in repairs and maintenance, power and utilized firm transportation expense resulting from the decrease in CBM gas sales volumes. Unit costs were also positively impacted by the decrease in total dollars which was offset, in part, by the decrease in CBM gas sales volumes.

•Depreciation, depletion and amortization costs attributable to the CBM segment were $86 million for the year ended December 31, 2016 compared to $84 million for the year ended December 31, 2015. These amounts included depletion on a unit of production basis of $0.82 per Mcf and $0.73 per Mcf, respectively. The remaining depreciation, depletion and amortization costs were either recorded on a straight-line basis or related to gas well closing.

The Other Gas segment includes activity not assigned to the Marcellus, Utica, or CBM segments. This segment also includes purchased gas activity, unrealized gain or loss on commodity derivative instruments, exploration and production related other costs, other corporate expenses and miscellaneous operational activity not assigned to a specific E&P segment.

Other Gas sales volumes are primarily related to shallow oil and gas production, as well as the Chattanooga shale in Tennessee. Natural gas, NGLs and oil sales related to the Other Gas segment were $41 million for the year ended December 31, 2016 compared to $55 million for the year ended December 31, 2015. The decrease in natural gas and oil sales primarily related to the $0.24 per Mcf decrease in average gas sales price. Total exploration and production costs related to these other sales were $76 million for the year ended December 31, 2016 compared to $115 million for the year ended December 31, 2015. The decrease was primarily due to a decrease in depreciation, depletion and amortization costs related to the adjustment to the Company's shallow oil and gas rates after an impairment in the carrying value was recognized in the second quarter of 2015 (see Note 9 - Property, Plant and Equipment of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information).

The Other Gas segment recognized an unrealized loss on commodity derivative instruments of $386 million as well as cash settlements of $17 million for the year ended December 31, 2016. For the year ended December 31, 2015, the Company recognized an unrealized gain on commodity derivative instruments of $197 million as well as cash settlements of $22 million. The unrealized loss/gain on commodity derivative instruments represents changes in the fair value of all of the Company's existing commodity hedges on a mark-to-market basis and is the result of the December 31, 2014 de-designation of all derivative positions as cash flow hedges. Changes in fair value were recorded in Accumulated Other Comprehensive Income prior to de-designation.

Purchased gas volumes represent volumes of gas purchased at market prices from third-parties and then resold in order to fulfill contracts with certain customers. Purchased gas sales revenues were $43 million for the year ended December 31, 2016 compared to $14 million for the year ended December 31, 2015. Purchased gas costs were $43 million for the year ended December 31, 2016 compared to $11 million for the year ended December 31, 2015. The period-to-period increase in purchased gas sales revenue was due to the increase in purchased gas sales volumes, offset, in part, by the decrease in market prices.

Total Miscellaneous Other Income	$	81	$	62	$	19	30.6	%

• Right of Way Sales increased $13 million in the period-to-period comparison due to an initiative in the current year to generate additional revenue from our unutilized surface rights.

• Equity in Earnings of Affiliates increased $5 million primarily due to an increase in earnings from CONE Midstream Partners LP and CONE Gathering LLC. See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information. 

Gain on sale of assets was $14 million for the year ended December 31, 2016 compared to $13 million for the year ended December 31, 2015. The $1 millionincrease was due to various land asset sales that occurred throughout both periods, none of which were individually material.

Exploration and production related other costs were $15 million for the year ended December 31, 2016 compared to $10 million for the year ended December 31, 2015. The $5 million increase in costs is primarily related to the following items:

	For the Years Ended December 31,

Total Exploration and Other Costs	$	15	$	10	$	5		50.0	%

• Lease Expiration Costs increased by $3 million in the period-to-period comparison, primarily due to an increase in the number of leases allowed to expire in the year ended December 31, 2016 as compared to the year ended December 31, 2015.

Other corporate expenses were $88 million for the year ended December 31, 2016 compared to $66 million for the year ended December 31, 2015. The $22 million increase in the period-to-period comparison was made up of the following items:

63

	For the Years Ended December 31,
	2016		2015		Variance			Percent Change
Severance Expense	$	1	$	5	$	(4	)	(80.0	)%

Other	9		4		5			125.0	%
Total Other Corporate Expenses	$	88	$	66	$	22		33.3	%

• Severance Expense decreased $4 million in the period-to-period comparison primarily due to the Company reorganization that occurred in the third quarter of 2015. Amounts recorded in the current period are primarily due to the Company's first quarter 2016 reorganization.

• Unutilized Firm Transportation and Processing Fees represent pipeline transportation capacity the E&P segment has obtained to enable gas production to flow uninterrupted as sales volumes increase, as well as additional processing capacity for natural gas liquids. The increase in the period-to-period comparison was primarily due to the decrease in the utilization of capacity. The Company attempts to minimize this expense by releasing (selling) unutilized firm transportation capacity to other parties when possible and when beneficial. The revenue received when this capacity is released (sold) is included in Gathering Revenue in miscellaneous other income above.

• Transaction Fees of $4 million are associated with the dissolution of the Noble Energy Marcellus Shale joint venture.

• Idle Rig Expense related to temporary idling of some of the Company's natural gas rigs. The total idle rig expense increased in the period-to-period comparison due to unfavorable market conditions in the first half of the current period.

• Other increased $5 million in the period-to-period comparison primarily due to a 401(k) discretionary contribution in the current period, as well as various transactions that occurred throughout both periods, none of which were individually material.

Impairment of Exploration and Production Properties of $829 million for the year ended December 31, 2015 relates to the write down of the Company's shallow oil and gas asset values in June 2015. See Note 9- Property, Plant and Equipment of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information. No such write downs occurred in the current period.

Selling, general and administrative (SG&A) costs are allocated to the total E&P segment based on percentage of total revenue and percentage of total projected capital expenditures. SG&A costs were $102 million for each of the years ended December 31, 2016 and December 31, 2015. Refer to the discussion of total company selling, general and administrative costs contained in the section "Net Loss Attributable to CONSOL Energy Shareholders" of this annual report for a detailed cost explanation.

Interest expense related to the E&P division was $3 million for the year ended December 31, 2016 compared to $6 million for the year ended December 31, 2015. Interest was incurred by the Other Gas segment on interest allocated to the E&P division under CONSOL Energy's credit facility.

Coal Sales

PA Mining Operations coal sales were $1,066 million for the year ended December 31, 2016, compared to $1,289 million for the year ended December 31, 2015. The $223 milliondecrease was attributable to a $13.05 per ton lower average sales price, offset by a 1.7 million increase in tons sold. The lower average sales price per PA Mining Operations ton sold was primarily the result of the continued decline in both the domestic and global thermal coal markets, particularly in the first half of 2016. The decline was related to higher customer inventories and lower gas prices after persistently mild 2015 weather.

65

The increase in overall tons sold reflects the improvement in both domestic and international coal demand throughout the second half of 2016.

Freight Revenue and Freight Expense

Freight revenue is the amount billed to customers for transportation costs incurred. This revenue is based on the weight of coal shipped, negotiated freight rates and method of transportation, primarily rail, used by the customers to which the Company contractually provides transportation services. Freight revenue is completely offset in freight expense. Freight revenue and freight expense were both $46 million for the year ended December 31, 2016, compared to $20 million for the year ended December 31, 2015. The $26 millionincrease was due to increased shipments where transportation services were contractually provided.

Miscellaneous Other Income

Miscellaneous other income was $13 million for the year ended December 31, 2016, compared to $4 million for the year ended December 31, 2015. Approximately $6 million of the increase was the result of a partial coal contract buyout in the current period. The remaining $3 million increase was the result of various transactions that occurred during both periods, none of which were individually material.

Operating Costs and Expenses

Operating costs and expenses are comprised of costs related to produced tons sold, along with changes in both the volumes and carrying values of coal inventory. Operating costs and expenses include items such as direct operating costs, royalty and production taxes, employee-related expenses and depreciation, depletion, and amortization costs. Total operating costs and expenses for the PA Mining Operations division were $845 million for the year ended December 31, 2016, or $111 millionlower than the $956 million for the year ended December 31, 2015. Total costs per PA Mining Operations ton sold were $34.35 per ton in the year ended December 31, 2016, compared to $41.78 per ton in the year ended December 31, 2015. The decrease in the cost of coal sold was driven by the idling of one longwall at the PA Mining Operations complex for approximately 90 days, a reduction of staffing levels, vendor concessions and a realignment of employee benefits. All of the above steps resulted in more consistent operating schedules, reduced labor costs and improved productivity. Productivity for the year ended December 31, 2016, as measured by tons per employee hour, improved by 17% compared to the year earlier period, despite the reduced number of longwalls in operation.

Other Costs and Expenses

Other costs and expenses include items that are assigned to the PA Mining Operations division but are not included in unit costs. Other costs and expenses increased$168 million in the year ended December 31, 2016 compared to the year ended December 31, 2015. The increase was due to the following:

No such transactions occurred during the year ended December 31, 2016.

• Idle Mine Costs increased $19 million, due to the temporary idling of one longwall at the PA Mining Operations complex for approximately 90 days in the first half of 2016 to optimize operating schedules.

66

• Purchased Coal Costs increased $6 million due to higher volumes of coal that needed to be purchased to fulfill various contracts.

• Litigation expense relates to approximately $3 million of costs which were incurred during the year ended December 31, 2016 related to the proposed consent decree with respect to the Bailey mine complex. See Note 22 - Commitments and Contingent Liabilities of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information. The remaining change was the result of various transactions that occurred, none of which were individually material.

• Severance Expense of $1 million was incurred during the year ended December 31, 2016 in connection with the Company's ongoing cost reduction efforts. No such transactions occurred in the prior period.

• Other increased $10 million in the period-to-period comparison primarily due to a 401(k) discretionary contribution in the current period.

Selling, General and Administrative Costs

Upon execution of the CNXC IPO, CNXC entered into a service agreement with CONSOL Energy that required CONSOL Energy to provide certain selling, general and administrative services. These services are paid monthly based on an agreed-upon fixed fee that is reset at least annually. See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information. The amount of selling, general and administrative costs related to PA Mining Operations was $38 million for the year ended December 31, 2016, compared to $41 million for the year ended December 31, 2015. Refer to the discussion of total Company selling, general and administrative costs contained in the section "Net Loss Attributable to CONSOL Energy Shareholders"of this annual report for a detailed cost explanation.

Interest Expense

Interest expense, net of amounts capitalized, of $9 million and $3 million for the years ended December 31, 2016 and 2015, respectively, is primarily comprised of interest on the CNXC revolving credit facility that was drawn upon after the CNXC IPO on July 7, 2015.

See Note 14 - Pension and Other Postretirement Benefits Plans in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information.

• Purchased Coal decreased$1 million due to lower volumes of coal that needed to be purchased to fulfill various contracts.

• Lease Rental Expense decreased$1 million primarily due to the buyout of certain leased equipment in the current period.

69

• Coal Terminal Operations decreased$2 million due to a reduction in labor costs.

• UMWA OPEB Expense decreased$4 million primarily due to a decrease in interest costs.

• Severance Payments decreased$5 million in the period-to-period comparison, primarily related to the company reorganization that occurred in the year ended December 31, 2015.

• Pension Expense decreased$20 million in the period-to-period comparison due to a decrease in actuarially-calculated amortization related to modifications made to the pension plan in May 2015. See Note 14 - Pension and Other Postretirement Benefits Plans in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information.

Selling, General and Administrative Costs

Selling, general and administrative costs allocated to the Other division were $13 million for the year ended December 31, 2016, compared to $15 million for the year ended December 31, 2015. Refer to the discussion of total Company selling, general and administrative costs contained in the section "Net Loss Attributable to CONSOL Energy Shareholders"of this annual report for more information.

Depreciation, Depletion and Amortization

Depreciation, depletion and amortization decreased $8 million in the period-to-period comparison, primarily related to a reduction of the asset retirement obligations at various closed and idled mine locations.

Loss on Debt Extinguishment

Loss on debt extinguishment of $68 million was recognized in the year ended December 31, 2015 due to the partial purchase of the 8.25% senior notes that were due in 2020 at an average price equal to 104.6% of the principal amount, and the partial purchase of the 6.375% senior notes that were due in 2021 at an average price equal to 105.0% of the principal amount. No such transactions occurred in the current period.

Interest Expense

Interest expense of $179 million was recognized in the year ended December 31, 2016, compared to $190 million in the year ended December 31, 2015. The $11 million decrease in the period-to-period comparison was due to the partial payoff of the 2020 and 2021 bonds in March and April 2015. Also contributing to the decrease was a decrease in the average outstanding balance on the Company's revolving credit facility, as well as lower interest rates on the 2023 bonds issued in March 2015 when compared to the interest rate on the 2020 bonds.

Income Taxes

The effective income tax rate for continuing operations when excluding non-controlling interest was (1.9)% for the year ended December 31, 2016, compared to 26.3% for the year ended December 31, 2015. During the year ended December 31, 2016, CONSOL Energy settled a Federal audit of the years 2010-2013 and received a favorable private letter ruling from the IRS related to bonus depreciation. Overall, the Company received approximately $21 million in refunds during 2016 and anticipates additional cash refunds in 2017.

Some of the factors contributing to these refunds put pressure on deferred tax assets related to AMT credits. Although these credits never expire, at December 31, 2016, management could not demonstrate sufficient positive evidence to ensure realizability of these assets in the foreseeable future. As CONSOL Energy was in a three-year cumulative pre-tax loss, the Company did not consider future generation of income to support the realization of these credits. As a result, the Company recorded a valuation allowance of $167 million at December 31, 2016. These credits can be fully utilized when sufficient operating income is generated by the Company.

An additional $38 million valuation allowance was recorded against state deferred tax assets related to state net operating losses and other temporary differences, Federal charitable contribution and foreign tax credit carryforwards.

CONSOL Energy consists of two principal business divisions: Exploration and Production (E&P) and Pennsylvania (PA) Mining Operations. The E&P division includes four reportable segments: Marcellus, Utica, Coalbed Methane (CBM) and Other Gas.

The E&P division contributed a loss before income tax of $679 million for the year ended December 31, 2015, compared to earnings before income tax of $190 million for the year ended December 31, 2014. Included in the 2015 net loss before income tax was a loss of $829 million primarily related to the impairment of the carrying value of CONSOL Energy's shallow oil and natural gas assets due to depressed NYMEX forward strip prices (see Note 9 - Property, Plant and Equipment of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information).

The following table presents a breakout of net liquid and natural gas sales information to assist in the understanding of the Company’s natural gas production and sales portfolio.

The E&P division natural gas, NGLs, and oil sales were $729 million for the year ended December 31, 2015, compared to $1,008 million for the year ended December 31, 2014. The decrease was primarily due to the 46.0% decrease in the average Gas sales price per Mcf without the impact of derivative instruments, offset in part, by the 39.5% increase in total E&P sales volumes. The decrease in average sales price was the result of the overall decrease in general market prices.

The E&P division sales volumes, average sales price (including the effects of derivative instruments), and average costs for all active E&P operations were as follows: 

	For the Years Ended December 31,
	2015		2014		Variance			Percent Change
E&P Sales Volumes (Bcfe)	328.7		235.7		93.0			39.5	%
Average Sales Price (per Mcfe)	$	2.81	$	4.37	$	(1.56	)	(35.7	)%

Average Margin	$	0.19	$	1.24	$	(1.05	)	(84.7	)%

Changes in the average costs per Mcfe were primarily related to the following items:

• The improvement in unit costs is primarily due to the continuing shift towards lower cost Marcellus and Utica Shale production, ongoing cost reduction efforts and the 39.5% increase in total volumes sold in the period-to-period comparison. Marcellus production made up 52.4% of E&P sales volumes in the year ended December 31, 2015, compared to 47.4% in the year ended December 31, 2014. Utica production made up 17.1% of E&P sales volumes in the year ended December 31, 2015, compared to 7.1% in the year ended December 31, 2014.

• Depreciation, depletion and amortization decreased on a per-unit basis primarily due to the adjustment to the Company's shallow oil and gas rates following the impairment in carrying value that was recognized in the second quarter of 2015 (see Note 9 - Property, Plant and Equipment in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for more information), as well as the increase in E&P sales volumes from the Company's lower cost Marcellus and Utica production. The decrease was offset, in part, by an overall increase in rates due to the reduction in the 2015 year-end reserves, as well as an increase in total dollars as production continued to grow.

• Lease operating expenses decreased on a per-unit basis in the period-to-period comparison due to the overall increase in E&P sales volumes. The decrease in unit costs was partially offset by an increase in repairs and maintenance, salt water disposal costs, and contractual services related to well tending.

The PA Mining Operations division had earnings before income tax of $405 million for the year ended December 31, 2015, compared to earnings before income tax of $431 million for the year ended December 31, 2014.

Sales tons, average sales price and average cost of goods sold per ton for the PA Mining Operations division were as follows:

	For the Years Ended December 31,
	2015		2014		Variance			Percent Change
Company Produced PA Mining Operations Tons sold (in millions)	22.9		26.1		(3.2		)	(12.3	)%
Average Sales Price per ton sold	$	56.36	$	61.88	$	(5.52	)	(8.9	)%
Average Cost of Goods Sold per ton	41.78		43.63		(1.85		)	(4.2	)%
Average Margin	$	14.58	$	18.25	$	(3.67	)	(20.1	)%

The lower average sales price per ton sold in the 2015 period was primarily the result of the continued decline in both the domestic and global thermal coal markets. Due to the weak domestic thermal spot market, the PA Mining Operations division priced 5.5 million tons on the export market for the year ended December 31, 2015, compared to 3.3 million tons for the year ended December 31, 2014. All other tons were sold on the domestic market.

Changes in the average cost of goods sold per ton were primarily driven by improved operational efficiencies, better geological conditions, a reduced workforce, a decrease in stream subsidence expense and other ongoing cost reduction efforts. In order to preserve margins, PA Mining Operations moved to a four-day work week in May 2015, compared to a normal five-day per week schedule. The decrease in unit costs was primarily the result of Pension and OPEB plan modifications for active employees in

73

September 2014. Refer to the discussion of total Company long-term liabilities below for more information on the effect of the Pension and OPEB plan modifications.

The Other division includes other business activities not assigned to the E&P or PA Mining Operations divisions, income taxes, and industrial supplies activity (this subsidiary was sold in December 2014). The Other division had a net loss of $77 million for the year ended December 31, 2015, compared to a net loss of $452 million for the year ended December 31, 2014.

Selling, general and administrative (SG&A) costs are allocated to the PA Mining Operations division based upon a shared service agreement that CONSOL Energy entered into with CNX Coal Resources LP (CNXC) upon execution of the CNXC initial public offering (IPO). The shared service agreement calls for CONSOL Energy to provide certain selling, general and administrative services that are paid for monthly, based on an agreed upon fixed fee that is reset at least annually. See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information. The remaining SG&A costs are allocated between the E&P and Other divisions based primarily on a percentage of total revenue and a percentage of total projected capital expenditures.

SG&A costs are excluded from the E&P and PA Mining Operations unit costs above. SG&A costs were $158 million for the year ended December 31, 2015, compared to $211 million for the year ended December 31, 2014. SG&A costs decreased due to the following items:

• The decrease in Short-Term Incentive Compensation was a result of lower payouts in the current period.

• Stock-Based Compensation decreased$15 million in the period-to-period comparison primarily due to accelerated non-cash amortization recorded in the prior period for employees who received awards under the Company's Equity Incentive Plan.

• Contributions decreased$8 million primarily due to a charitable contribution of $6 million to the Boy Scouts of America that was recorded during the year ended December 31, 2014. The remaining $2 million decrease is due to various transactions that occurred throughout both periods, none of which were individually material.

• Employee Wages and Related Expenses decreased$8 million primarily due to the Company reorganization that occurred in the year ended December 31, 2015.

• Consulting and Professional Services decreased$5 million due to various transactions that occurred throughout both periods, none of which were individually material, including a general decrease in legal expenses during the year ended December 31, 2015.

Total Company long-term liabilities, such as Other Post-Employment Benefits (OPEB), the salary retirement plan, workers' compensation, Coal Workers' Pneumoconiosis (CWP), and long-term disability are actuarially calculated for the Company as a whole. In general, the expenses are then allocated to the segments based upon criteria specific to each liability. Total CONSOL Energy continuing operations expense related to actuarial liabilities was income of $162 million for the year ended December 31, 2015, compared to expense of $96 million for the year ended December 31, 2014. The decrease of $258 million was primarily due to modifications made to the OPEB and Pension plans in September 2014 and May 2015. Not included in the 2014 long-term liability expense totals discussed above is $46 million of expense for cash payments made to active employees in the fourth quarter of 2014. See Note 14—Pension and Other Postretirement Benefit Plans and Note 15—Coal Workers' Pneumoconiosis (CWP) and Workers' Compensation in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional details.

* NGLs and Condensate are converted to Mcfe at the rate of one barrel equals six Mcf based upon the approximate relative energy content of oil and natural gas, which is not indicative of the relationship of oil, NGLs, condensate, and natural gas prices.

The Marcellus segment had natural gas, NGLs and oil sales of $379 million for the year ended December 31, 2015 compared to $457 million for the year ended December 31, 2014. The $78 million decrease was primarily due to a 45.3%decrease in the average gas sales price in the period-to-period comparison, partially offset by a 54.3%increase in total Marcellus sales volumes. The increase in total sales volumes is primarily due to additional wells coming on-line in the current period.

The decrease in the total average Marcellus sales price was primarily the result of the $1.73 per Mcf decrease in gas market prices, along with a $0.17 per Mcfe decrease in the uplift from NGLs and condensate sales volumes, when excluding the impact of hedging. These decreases were offset, in part, by a $0.52 per Mcf increase in the gain on commodity derivative instruments resulting from the Company's hedging program. The increase in the gain was due to an increase in volumes hedged and lower market prices. These financial hedges represented approximately 90.3 Bcf of the Company's produced Marcellus gas sales volumes for the year ended December 31, 2015 at an average gain of $1.09 per Mcf. For the year ended December 31, 2014, these financial hedges represented approximately 70.4 Bcf at an average gain of $0.21 per Mcf.

Total exploration and production costs for the Marcellus segment were $424 million for the year ended December 31, 2015 compared to $300 million for the year ended December 31, 2014. The increase in total dollars and decrease in unit costs for the Marcellus segment are due to the following items:

•Marcellus lease operating expense was $44 million for the year ended December 31, 2015 compared to $46 million for the year ended December 31, 2014. The decrease in total dollars was primarily due to a reduction in employee related costs in the year ended December 31, 2015. The decrease in unit costs was primarily due to the 54.3%increase in total Marcellus sales volumes.

•Marcellus production, ad valorem, and other fees were $18 million for the years ended December 31, 2015 and 2014. The decrease in unit costs was primarily due to the 54.3%increase in total Marcellus sales volumes offset, in part, by the decrease in total average Marcellus sales price.

76

•Marcellus transportation, gathering and compression costs were $200 million for the year ended December 31, 2015 compared to $104 million for the year ended December 31, 2014. The $96 million increase in total dollars was primarily related to an increase in the CONE gathering fee due to the increase in total Marcellus sales volumes (See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information), an increase in processing fees associated with natural gas liquids primarily due to the 74.3%increase in NGLs sales volumes, and an increase in utilized firm transportation expense. The increase in unit costs was due to the overall increase in total dollars.

•Depreciation, depletion and amortization costs attributable to the Marcellus segment were $162 million for the year ended December 31, 2015 compared to $132 million for the year ended December 31, 2014. These amounts included depreciation on a unit of production basis of $0.92 per Mcf and $1.16 per Mcf, respectively. The remaining depreciation, depletion and amortization costs were either recorded on a straight-line basis or related to gas well closing.

UTICA SEGMENT

The Utica segment had a loss before income tax of $19 million for the year ended December 31, 2015 compared to earnings before income tax of $44 million for the year ended December 31, 2014.

*NGLs and Condensate are converted to Mcfe at the rate of one barrel equals six mcf based upon the approximate relative energy content of oil and natural gas, which is not indicative of the relationship of oil, NGLs, condensate, and natural gas prices.

The Utica segment had natural gas, NGLs and oil sales of $93 million for the year ended December 31, 2015 compared to $87 million for the year ended December 31, 2014. The $6 million increase was primarily due to the 236.5%increase in total Utica sales volumes, partially offset by the 56.1%decrease in average gas sales price. The 39.5 Bcfe increase in total Utica sales volumes was due to additional wells coming on-line, primarily in dry Utica areas, in the year ended December 31, 2015.

The decrease in the total average Utica sales price was primarily due to the $1.94 per Mcf decrease in average market prices, along with a $1.61 decrease in the uplift from NGLs and condensate sales volumes, when excluding the impact of hedging. These decreases were offset, in part, by a $0.05 per Mcf increase in the gain on commodity derivative instruments in the current period. Financial hedges represented approximately 5.9 Bcf of the Company's produced Utica gas sales volumes for the year ended December 31, 2015 at an average gain of $1.08 per Mcf. For the year ended December 31, 2014, these financial hedges represented approximately 3.5 Bcf at an average gain of $0.35 per Mcf.

77

Total exploration and production costs for the Utica segment were $118 million for the year ended December 31, 2015 compared to $44 million for the year ended December 31, 2014. The increase in total dollars and decrease in unit costs for the Utica segment are due to the following items:

•Utica lease operating expense was $22 million for the year ended December 31, 2015 compared to $18 million for the year ended December 31, 2014. The increase in total dollars was primarily due to the increase in production which resulted in increased repair and maintenance costs, as well as increased contractual services related to well tending. The decrease in unit costs was primarily due to the 236.5%increase in total Utica sales volumes.

•Utica production, ad valorem, and other fees were $2 million for the year ended December 31, 2015 compared to $1 million for the year ended December 31, 2014. The increase in total dollars was primarily due to an increase in severance tax expense caused by the increase in total Utica sales volumes. Unit costs were positively impacted by both the increased sales volumes and the decreased average sales price.

•Utica transportation, gathering and compression costs were $35 million for the year ended December 31, 2015 compared to $7 million for the year ended December 31, 2014. The $28 million increase in total dollars was primarily related to increased gathering and processing fees associated with the increased Utica NGLs and gas sales volumes. The increase in unit costs was due to the increase in total dollars and was offset, in part, by the increase in total Utica sales volumes.

•Depreciation, depletion and amortization costs attributable to the Utica segment were $59 million for the year ended December 31, 2015 compared to $18 million for the year ended December 31, 2014. These amounts included depreciation on a unit of production basis of $1.05 per Mcf and $1.09 per Mcf, respectively. The remaining depreciation, depletion and amortization costs were either recorded on a straight-line basis or related to gas well closing.    

COALBED METHANE (CBM) SEGMENT

The CBM segment had earnings before income tax of $60 million for the year ended December 31, 2015 compared to earnings before income tax of $108 million for the year ended December 31, 2014.

Average Margin for CBM (per Mcf)	$	0.80	$	1.36	$	(0.56	)	(41.2	)%

The CBM segment had natural gas sales of $202 million for the year ended December 31, 2015 compared to $343 million for the year ended December 31, 2014. The $141 million decrease was primarily due to a 37.5%decrease in the average gas sales price, as well as a 5.8%decrease in CBM gas sales volumes. The decrease in CBM sales volumes was primarily due to normal well declines and less drilling activity.

The total average CBM sales price decreased $0.77 per Mcf due primarily to a $1.62 per Mcf decrease in gas market prices. The decrease was offset, in part, by a $0.85 per Mcf increase in the gain on commodity derivative instruments resulting from the Company's hedging program. The increase in the gain was due to lower market prices. These financial hedges represented approximately 57.5 Bcf of the Company's produced CBM sales volumes for the year ended December 31, 2015 at an average gain

78

of $1.17 per Mcf. For the year ended December 31, 2014, these financial hedges represented approximately 70.0 Bcf at an average gain of $0.06 per Mcf.

Total exploration and production costs for the CBM segment were $209 million for the year ended December 31, 2015 compared to $239 million for the year ended December 31, 2014. The decrease in total dollars and decrease in unit costs for the CBM segment were due to the following items:

•CBM lease operating expense was $33 million for the year ended December 31, 2015 compared to $42 million for the year ended December 31, 2014. The decrease in total dollars was primarily related to a decrease in contractual services related to well tending and a decrease in repairs and maintenance expense. The decrease in unit costs was due to the decrease in total dollars, partially offset by the decrease in CBM gas sales volumes.

•CBM production, ad valorem, and other fees were $7 million for the year ended December 31, 2015 compared to $12 million for the year ended December 31, 2014. The $5 million decrease was due to a decrease in severance tax expense resulting from the decrease in both gas sales volumes and average sales price. Unit costs were positively impacted by the decrease in total average CBM sales price which was offset, in part, by the decrease in CBM gas sales volumes.

•CBM transportation, gathering and compression costs were $85 million for the year ended December 31, 2015 compared to $96 million for the year ended December 31, 2014. The $11 million decrease was primarily related to a decrease in repairs and maintenance, power and utilized firm transportation expense resulting from the decrease in CBM gas sales volumes. Unit costs were also positively impacted by the decrease in total dollars which was offset, in part, by the decrease in CBM gas sales volumes.

•Depreciation, depletion and amortization costs attributable to the CBM segment were $84 million for the year ended December 31, 2015 compared to $89 million for the year ended December 31, 2014. These amounts included depreciation on a unit of production basis of $0.73 per Mcf and $0.75 per Mcf, respectively. The remaining depreciation, depletion and amortization costs were either recorded on a straight-line basis or related to gas well closing.

OTHER GAS SEGMENT

The Other Gas segment had a loss before income tax of $776 million for the year ended December 31, 2015 compared to a loss before income tax of $134 million for the year ended December 31, 2014.

The Other Gas segment includes activity not assigned to the Marcellus, Utica, or CBM segments. This segment also includes purchased gas activity, unrealized gain or loss on commodity derivative instruments, exploration and production related other costs, other corporate expenses and miscellaneous operational activity not assigned to a specific E&P segment.

Other Gas sales volumes are primarily related to shallow oil and gas production, as well as the Chattanooga shale in Tennessee. Natural gas, NGLs and oil sales related to the Other Gas segment were $55 million for the year ended December 31, 2015 compared to $121 million for the year ended December 31, 2014. The decrease in natural gas and oil sales primarily related to the 49.8%decrease in average gas sales price. Total exploration and production costs related to these other sales were $115 million for the year ended December 31, 2015 compared to $158 million for the year ended December 31, 2014. The decrease was primarily due to a decrease in depreciation, depletion and amortization related costs related to the adjustment to the Company's shallow oil and gas rates after an impairment in the carrying value was recognized in the second quarter of 2015 (see Note 9 - Property, Plant and Equipment of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information), as well as a decrease in employee related costs.

The Other Gas segment recognized an unrealized gain on commodity derivative instruments of $197 million as well as cash settlements of $22 million for the year ended December 31, 2015. For the year ended December 31, 2014, the Company recognized cash settlements of $3 million. The unrealized gain on commodity derivative instruments represents changes in the fair value of all of the Company's existing commodity hedges on a mark-to-market basis and is the result of the December 31, 2014 de-designation of all derivative positions as cash flow hedges. Changes in fair value were recorded in Accumulated Other Comprehensive Income prior to de-designation.

Purchased gas volumes represent volumes of gas purchased at market prices from third-parties and then resold in order to fulfill contracts with certain customers. Purchased gas sales revenues were $14 million for the year ended December 31, 2015 compared to $9 million for the year ended December 31, 2014. Purchased gas costs were $11 million for the year ended December 31, 2015 compared to $7 million for the year ended December 31, 2014. The period-to-period increase in purchased gas sales revenue was due to the increase in purchased gas sales volumes, offset, in part, by the decrease in market prices.

• Equity in Earnings of Affiliates increased $15 million due to an increase in earnings from CONE Midstream Partners LP and CONE Gathering LLC. See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information.

• Gathering Revenue primarily relates to the release (sale) of unutilized firm transportation capacity when possible and when beneficial in order to minimize unutilized firm transportation expense. Gathering revenue decreased $14 million in the period-to-period comparison, primarily due to a decrease in the release of capacity.

Gain on sale of assets was $13 million for the year ended December 31, 2015 compared to $46 million for the year ended December 31, 2014. The $33 million decrease was primarily due to the sale of Utica rights in Marshall County, WV to Noble Energy, which closed in December 2014 and resulted in a pre-tax gain of $25 million. The remaining decrease was due to various land asset sales that occurred throughout both periods, none of which were individually material.

• Idle rig fees are related to the temporary idling of some of the Company's natural gas rigs. The Company incurred $19 million of idle rig fees during the year ended December 31, 2015 in response to declining market conditions. No idle rig fees were incurred during the year ended December 31, 2014.

• Severance Expense was a result of the Company reorganization that occurred in the 2015 period. There was no such expense in the 2014 period.

• Bank Fees decreased $4 million due to the termination of the CNX Gas Senior Secured Credit Agreement on June 18, 2014.

• Unutilized firm transportation costs represent pipeline transportation capacity that the E&P division has obtained to enable gas production to flow uninterrupted as sales volumes increase, as well as additional processing capacity for natural gas liquids. Unutilized Firm Transportation and Processing Fees decreased $5 million in the period-to-period comparison due to an increase in the utilization of the capacity. The Company attempts to minimize this expense by releasing (selling) unutilized firm transportation capacity to other parties when possible and when beneficial. This revenue is included in Gathering Revenue in miscellaneous other income above.

Impairment of Exploration and Production Properties of $829 million for the year ended December 31, 2015 relates to the write down of the Company's shallow oil and gas asset values in June 2015.

Coal Sales

PA Mining Operations coal sales were $1,289 million for the year ended December 31, 2015, compared to $1,617 million for the year ended December 31, 2014. The $328 milliondecrease was attributable to a 3.2million decrease in company produced tons sold and a $5.52lower average sales price per ton sold. The lower tons sold and average sales price per PA Mining Operations ton sold were primarily the result of the continued decline in both the domestic and global thermal coal markets. Due to the weak domestic thermal spot market, 5.5 million tons were sold on the export market for the year ended December 31, 2015, compared to 3.3 million tons for the year ended December 31, 2014.

Freight Revenue and Freight Expense

Freight revenue is the amount billed to customers for transportation costs incurred. This revenue is based on the weight of coal shipped, negotiated freight rates and method of transportation, primarily rail, used by the customers to which the Company contractually provides transportation services. Freight revenue is completely offset in freight expense. Freight revenue and freight expense were both $20 million for the year ended December 31, 2015, compared to $23 million for the year ended December 31, 2014. The $3 milliondecrease was due to decreased shipments where transportation services were contractually provided.

Miscellaneous Other Income

Miscellaneous other income was $4 million for the year ended December 31, 2015, compared to $38 million for the year ended December 31, 2014. Approximately $30 million of the decrease related to a coal customer contract buyout in the prior period. The remaining $4 milliondecrease was the result of various transactions that occurred during both periods, none of which were individually material.

Operating Costs and Expenses

Operating costs and expenses are comprised of costs related to produced tons sold, along with changes in both the volumes and carrying values of coal inventory. Operating costs and expenses include items such as direct operating costs, royalty and production taxes, employee-related expenses and depreciation, depletion, and amortization costs. Total operating costs and expenses for the PA Mining Operations division were $956 million for the year ended December 31, 2015, or $184 millionlower than the $1,140 million for the year ended December 31, 2014. Total costs per PA Mining Operations ton sold were $41.78 per ton in the year ended December 31, 2015, compared to $43.63 per ton in the year ended December 31, 2014. The decrease in the cost of coal sold was driven by improved operational efficiencies, better geological conditions, a reduced workforce, a decrease in stream subsidence expense and other ongoing cost reduction efforts. In order to preserve margins, PA Mining Operations moved to a four-day work week in May 2015, compared to a normal five-day per week schedule. The decrease in unit costs was primarily the result of a change in allocation methodology, whereby OPEB plan changes are no longer included in unit costs.

Other Costs And Expenses

Other costs and expenses include items that are assigned to the PA Mining Operations division but are not included in unit costs, such as OPEB plan changes (beginning in the 2015 period), coal reserve holding costs and purchased coal costs. Total other costs and expenses decreased$128 million in the year ended December 31, 2015 compared to the year ended December 31, 2014. The decrease was primarily due to income of $129 million related to OPEB plan changes made in May 2015 for retired employees. Refer to the discussion of total Company long-term liabilities contained in the section "Net (Loss) Income Attributable to CONSOL Energy Shareholders" of this annual report for a detailed cost explanation. No such transactions occurred during the year ended December 31, 2014.

Selling, General and Administrative Costs

Upon execution of the CNXC IPO, CNXC entered into a service agreement with CONSOL Energy that required CONSOL Energy to provide certain selling, general and administrative services. These services are paid monthly based on an agreed-upon fixed fee that is reset at least annually. See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information. The amount of selling, general and administrative costs related to PA Mining Operations was $41 million for the year ended December 31, 2015, compared to $69 million for the year ended December 31, 2014. Refer to the discussion of total Company selling, general and administrative costs contained in the section "Net (Loss) Income Attributable to CONSOL Energy Shareholders"of this annual report for a detailed cost explanation.

83

Interest Expense

Interest expense, net of amounts capitalized, of $3 million for the year ended December 31, 2015 is primarily comprised of interest on the CNXC revolving credit facility that was drawn upon after the CNXC IPO on July 7, 2015.

Refer to the discussion of total Company long-term liabilities contained in the section "Net (Loss) Income Attributable to CONSOL Energy Shareholders" of this annual report and Note 14—Pension and Other Postretirement Benefit Plans in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for more information.

• Purchased Coal costs decreased$13 million due to lower volumes of coal that needed to be purchased to fulfill various contracts.

• Closed and Idle Mines decreased$11 million, primarily due to a $7 million decrease in property taxes and a $5 million decrease in permitting and compliance costs. The remaining change was due to various transactions that occurred throughout both periods, none of which were individually material.

• Pension Settlement expense is required when lump sum distributions made for a given plan year exceed the total of the service and interest costs for that same plan year. Settlement accounting was triggered in both periods. See Note 14 - Pension and Other Postretirement Benefit Plans in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional detail.

Selling, General and Administrative Costs

Selling, general and administrative costs allocated to the Other division were $15 million for the year ended December 31, 2015, compared to $13 million for the year ended December 31, 2014. Refer to the discussion of total Company selling, general and administrative costs contained in the section "Net (Loss) Income Attributable to CONSOL Energy Shareholders" of this annual report for more information.

Depreciation, Depletion and Amortization

Deprecation, depletion, and amortization decreased $16 million in the period-to-period comparison, primarily related to a reduction of the asset retirement obligations at various closed and idled mine locations. The decrease was also the result of the Company's divestiture of its industrial supplies subsidiary in December 2014, as well as fewer assets placed in service in the period-to-period comparison.

Loss on Debt Extinguishment

Loss on debt extinguishment of $68 million was recognized in the year ended December 31, 2015 due to the partial purchase of the 8.25% senior notes that were due in 2020 at an average price equal to 104.6% of the principal amount, and the partial purchase of the 6.375% senior notes that were due in 2021 at an average price equal to 105.0% of the principal amount. Loss on debt extinguishment of $95 million was recognized in the year ended December 31, 2014 due to the purchase of all of the 8.00% senior notes that were due in 2017 at an average premium of 104.0% of the principal amount, and the partial purchase of the 8.25% senior notes that were due in 2020 at an average premium of 107.5% of the principal amount.

Interest Expense

Interest expense of $190 million was recognized in the year ended December 31, 2015, compared to $214 million in the year ended December 31, 2014. The $24 million decrease was primarily due to the partial payoff of the 2020 and 2021 bonds in the year ended December 31, 2015 and the early payoff of the 2017 bonds, issued in March 2015, and the 2022 bonds, issued in April and August 2014. The decrease was offset, in part, by interest on short-term borrowings.

Income Taxes

The effective income tax rate for continuing operations when excluding noncontrolling interest was 26.3% for the year ended December 31, 2015, compared to 8.3% for the year ended December 31, 2014. The effective rates for the years ended December 31, 2015 and 2014 were calculated using the annual effective rate projections on recurring earnings and include tax liabilities related to certain discrete transactions. For the year ended December 31, 2015, CONSOL Energy recognized certain tax benefits related to a prior-year tax provision. In order to maximize cash flow, CONSOL Energy elected to take bonus depreciation upon filing the 2014 tax return. As a result, CONSOL Energy realized a cash refund of $24 million for 2014. The bonus depreciation also created a net operating loss which was carried back to 2012. The carryback resulted in an additional cash refund of $31 million. However, these changes resulted in an expense of $27 million related to decreased percentage depletion deductions, offset, in part, by $5 million of tax benefit due to changes in the deduction for certain stock-related compensation.

For the year ended December 31, 2014, CONSOL Energy recognized certain tax benefits as a result of changes in estimates related to a prior-year tax provision that resulted in a benefit of $10 million primarily related to increased percentage of depletion. Also, the Internal Revenue Service issued its audit report relating to the examination of CONSOL Energy's 2008 and 2009 U.S. income tax returns during the year ended December 31, 2014. The result of these findings was a change in timing of certain tax

87

deductions which increased the tax benefit of percentage of depletion by $7 million. Also, as a result of closing the IRS audit, CONSOL Energy filed amended state income tax returns. The Company filed the required amended returns and realized a discrete state income tax charge of $5 million which was offset by a federal income tax benefit of $2 million. See Note 6 - Income Taxes in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information. 

Upon changes in facts and circumstances, management may conclude that deferred tax assets for which no valuation allowance is currently recorded may not be realizable in future periods, resulting in a future charge to record a valuation allowance. A valuation allowance is required when it is more likely than not that all or a portion of a deferred tax asset will not be realized. All available evidence, both positive and negative, must be considered in determining the need for a valuation allowance. Positive evidence considered includes financial and tax earnings generated over the past three years, future income projections based on existing fixed price contracts and forecasted expenses, reversals of financial to tax temporary differences and the implementation of and/or ability to employ various tax planning strategies. Negative evidence includes financial and tax losses generated in prior periods and the inability to achieve forecasted results for those periods. Existing valuation allowances are re-examined under the same standards of positive and negative evidence. If it is determined that it is more likely than not that a deferred tax asset will be realized, the appropriate amount of the valuation allowance, if any, is released. Deferred tax assets and liabilities are also re-measured to reflect changes in underlying tax rates due to law changes. For the year ended December 31, 2015, a review of positive and negative evidence regarding these tax benefits concluded that the valuation allowances for various CONSOL Energy subsidiaries was warranted. As a result, CONSOL Energy recorded a valuation allowance of $65 million against certain deferred tax assets that the Company determined would not be realized.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make judgments, estimates and assumptions that affect reported amounts of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities in the Consolidated Financial Statements and at the date of the financial statements. See Note 1-Significant Accounting Policies in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for further discussion. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making the judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates on an on-going basis. Actual results could differ from those estimates upon subsequent resolution of identified matters. Management believes that the estimates utilized are reasonable. The following critical accounting policies are materially impacted by judgments, assumptions and estimates used in the preparation of the Consolidated Financial Statements.

Other Post Employment Benefits (OPEB), Salaried Pensions, Workers’ Compensation and Coal Workers’ Pneumoconiosis (CWP)

Liabilities and expenses for OPEB, pension, workers’ compensation and CWP are determined using actuarial methodologies and incorporate significant assumptions, including the interest rate used to discount the future estimated liability, the expected long-term rate of return on plan assets, and several assumptions relating to the employee workforce (salary increases, health care cost trend rates, retirement age, and mortality).

The interest rate used to discount future estimated liabilities is determined using a Company-specific yield curve model (above-mean) developed with the assistance of an external actuary. The Company-specific yield curve uses a subset of the expanded bond universe to determine the Company-specific discount rate. Bonds used in the yield curve are rated AA by Moody’s or Standard & Poor’s as of the measurement date. The yield curve model parallels the plans’ projected cash flows.

The assumed rate of return on plan assets can also impact CONSOL Energy’s pension liability. The market related asset value is derived by taking the cost value of assets as of December 31, 2016 and multiplying it by the average 36-month ratio of the market value of assets to the cost value of assets. CONSOL Energy’s pension plan weighted average asset allocations at December 31, 2016 consisted of 50% equity securities and 50% debt securities.

88

The estimated liabilities recognized at December 31, 2016 and the benefit payments made for the year end December 31, 2016 were as follows:

Plan	Estimated Liability as of December 31, 2016	Benefit Payments for the year ended December 31, 2016
OPEB	$700,085	$45,387
Pension	$115,447	$2,726
Workers’ Compensation	$79,693	$17,028
CWP	$118,836	$11,409

Mine Closure and Gas Well Closing Obligations

The Surface Mining Control and Reclamation Act established operational, reclamation and closure standards for all aspects of surface mining as well as most aspects of deep mining. CONSOL Energy accrues for the costs of current coal mine disturbance and final coal mine and gas well closure, including the cost of treating mine water discharge where necessary. Estimates of our total mine-closing and gas well closing liabilities, which are based upon permit requirements and CONSOL Energy engineering expertise related to these requirements, including the current portion, were approximately $473.5 million at December 31, 2016. This liability is reviewed annually, or when events and circumstances indicate an adjustment is necessary, by CONSOL Energy management and engineers. The estimated liability can significantly change if actual costs vary from assumptions or if governmental regulations change significantly.

Accounting for Asset Retirement Obligations requires that the fair value of an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The present value of the estimated asset retirement costs is capitalized as part of the carrying amount of the long-lived asset. Asset retirement obligations primarily relate to the closure of mines and gas wells and the reclamation of land upon exhaustion of coal and gas reserves. Changes in the variables used to calculate the liabilities can have a significant effect on the mine closing and gas well closing liabilities. The amounts of assets and liabilities recorded are dependent upon a number of variables, including the estimated future retirement costs, estimated proved reserves, assumptions involving profit margins, inflation rates and the assumed credit-adjusted risk-free interest rate.

Accounting for Asset Retirement Obligations also requires depreciation of the capitalized asset retirement cost and accretion of the asset retirement obligation over time. The depreciation will generally be determined on a units-of-production basis, whereas the accretion to be recognized will escalate over the life of the producing assets, typically as production declines.

Income Taxes

Deferred tax assets and liabilities are recognized using enacted tax rates for the estimated future tax effects of temporary differences between the book and tax basis of recorded assets and liabilities. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion of the deferred tax asset will not be realized. All available evidence, both positive and negative, must be considered in determining the need for a valuation allowance. At December 31, 2016, CONSOL Energy has deferred tax assets in excess of deferred tax liabilities of approximately $4 million. At December 31, 2016, CONSOL Energy had a valuation allowance of $283 million on deferred tax assets.

CONSOL Energy evaluates all tax positions taken on the state and federal tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that meet the more likely than not to be sustained criteria, an evaluation to determine the largest amount of benefit, determined on a cumulative probability basis that is more likely than not to be realized upon ultimate settlement is determined. A previously recognized tax position is reversed when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the probable amount that is more likely than not is based on judgment, historical experience and on various other assumptions that we believe are reasonable under the circumstances. The results of these estimates, that are not readily apparent from other sources, form the basis for recognizing an uncertain tax liability. Actual results could differ from those estimates upon subsequent resolution of identified matters. CONSOL Energy has $9 million of uncertain tax liabilities at December 31, 2016.

Stock-Based Compensation

As of December 31, 2016, we have issued four types of share-based payment awards: options, restricted stock units, performance stock options, and performance share units. 

89

The fair value of each restricted stock unit awarded is equivalent to the closing market price of a share of the Company's stock on the date of the grant. The fair value of each performance share unit is determined by a Monte Carlo simulation method. The fair value of each option is determined using the Black-Scholes option pricing model. All outstanding performance stock options are fully vested.

As of December 31, 2016, $40,234 of total unrecognized compensation cost related to unvested awards is expected to be recognized over a weighted-average period of 2.73 years. See Note 17 - Stock-based Compensation in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for more information.

Contingencies

CONSOL Energy is currently involved in certain legal proceedings. We have accrued our estimate of the probable costs for the resolution of these claims. This estimate has been developed in consultation with legal counsel involved in the defense of these matters and is based upon the nature of the lawsuit, progress of the case in court, view of legal counsel, prior experience in similar matters, and management's intended response. Future results of operations for any particular quarter or annual period could be materially affected by changes in our assumptions or the outcome of these proceedings. Legal fees associated with defending these various lawsuits and claims are expensed when incurred. See Note 22-Commitments and Contingent Liabilities in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for more information.

Derivative Instruments

CONSOL Energy enters into financial derivative instruments to manage exposure to natural gas and oil price volatility. We measure every derivative instrument at fair value and record them on the balance sheet as either an asset or liability. Changes in fair value of derivatives are recorded currently in earnings unless special hedge accounting criteria are met. For derivatives designated as fair value hedges, the changes in fair value of both the derivative instrument and the hedged item are recorded in earnings. For derivatives designated as cash flow hedges, the effective portions of changes in fair value of the derivative are reported in other comprehensive income or loss and reclassified into earnings in the same period or periods which the forecasted transaction affects earnings. The ineffective portions of hedges are recognized in earnings in the current year. Prior to de-designation CONSOL Energy utilized only cash flow hedges that were considered highly effective.

CONSOL Energy formally assesses, both at inception of the hedge and on an ongoing basis, whether each derivative is highly effective in offsetting changes in fair values or cash flows of the hedge item. If it is determined that a derivative is not highly effective as a hedge or if a derivative ceases to be a highly effective hedge, CONSOL Energy will discontinue hedge accounting prospectively.

On December 31, 2014, CONSOL Energy de-designated all of its derivative positions as hedging instruments. Subsequent changes in fair value were recorded in current earnings. Deferred gains and losses in other comprehensive income as of that date were recorded in earnings when the related physical transaction occured.

Natural Gas, NGL, Condensate and Oil Reserve ("Natural Gas Reserve") and Coal Reserve Values

There are numerous uncertainties inherent in estimating quantities and values of economically recoverable natural gas and coal reserves, including many factors beyond our control. As a result, estimates of economically recoverable natural gas and coal reserves are by their nature uncertain. Information about our reserves consists of estimates based on engineering, economic and geological data assembled and analyzed by our staff. Our natural gas reserves are reviewed by independent experts each year. Our coal reserves are periodically reviewed by an independent third party consultant. Some of the factors and assumptions which impact economically recoverable reserve estimates include:

• geological conditions;

• historical production from the area compared with production from other producing areas;

• the assumed effects of regulations and taxes by governmental agencies;

• assumptions governing future prices; and

• future operating costs.

Each of these factors may in fact vary considerably from the assumptions used in estimating reserves. For these reasons, estimates of the economically recoverable quantities of gas and coal attributable to a particular group of properties, and classifications of these reserves based on risk of recovery and estimates of future net cash flows, may vary substantially. Actual

90

production, revenues and expenditures with respect to our reserves will likely vary from estimates, and these variances may be material. See "Risk Factors" in Item 1A of this report for a discussion of the uncertainties in estimating our reserves.

Impairment of Long-lived Assets:

CONSOL Energy performs a quantitative annual impairment test during the fourth quarter of each year over proved properties using the published NYMEX forward prices, timing, methods and other assumptions consistent with historical periods. During interim periods, management updates these annual tests whenever events or changes in circumstances indicate that a property’s carrying amount may not be recoverable. Impairment tests require that the Company first compare future undiscounted cash flows by asset group to their respective carrying values. If the carrying amount exceeds the estimated undiscounted future cash flows, a reduction of the carrying amount of the natural gas properties to their estimated fair values is required, which is determined based on discounted cash flow techniques using a market-specific weighted average cost of capital. During the year ended December 31, 2015, certain of the Company’s proved properties, primarily shallow oil and gas assets, failed the undiscounted cash flow portion of the test. After performing the discounted cash flow portion of the test, CONSOL Energy recorded an impairment of $824,742 in the Impairment of Exploration and Production Properties in the Consolidated Statements of Income. See Note 1 - Significant Accounting Policies in Item 8 of this Form 10-K for more information.

There were no other additional impairments related to proved properties in the year ended December 31, 2015. There were no such impairments for the years ended December 31, 2016 or 2014.

CONSOL Energy evaluates capitalized costs of unproved gas properties for recoverability on a prospective basis. Indicators of potential impairment include potential shifts in business strategy, overall economic factors and historical experience. If it is determined that the properties will not yield proved reserves, the related costs are expensed in the period the determination is made. For the year ended December 31, 2015, unproved property impairments related to the determination that the properties will not yield proved reserves were $4,163 and are included in Impairment of Exploration and Production Properties in the Consolidated Statements of Income. No such impairments occurred in the year ended December 31, 2016. See Note 1 - Significant Accounting Policies in Item 8 of this Form 10-K for more information.

There were no other additional impairments related to unproved properties in the year ended December 31, 2015. There were no such impairments for the years ended December 31, 2016 and 2014.

Liquidity and Capital Resources

CONSOL Energy generally has satisfied its working capital requirements and funded its capital expenditures and debt service obligations with cash generated from operations and proceeds from borrowings. On June 18, 2014, CONSOL Energy entered into a five year Credit Agreement for a $2.0 billion senior secured revolving credit facility. In November 2016, the Company's lending group reaffirmed the $2.0 billion borrowing base of the facility, which expires on June 18, 2019. The facility is secured by substantially all of the assets of CONSOL Energy and certain of its subsidiaries. CONSOL Energy's credit facility allows for up to $2.0 billion of borrowings, which includes a $750 million letters of credit aggregate sub-limit. CONSOL Energy can request an additional $500 million increase in the aggregate borrowing limit amount. Fees and interest rate spreads are based on the percentage of facility utilization, measured quarterly. Availability under the facility is limited to a borrowing base, which is determined by the lenders syndication agent and approved by the required number of lenders in good faith by calculating a value of CONSOL Energy's proved gas reserves. The facility includes a minimum interest coverage ratio covenant of no less than 2.50 to 1.00, measured quarterly. The interest coverage ratio is calculated as the ratio of Adjusted EBITDA to cash interest expense of CONSOL Energy and certain of its subsidiaries, excluding CNXC. The interest coverage ratio was 3.49 to 1.00 at December 31, 2016. Adjusted EBITDA, as used in the covenant calculation, excludes non-cash compensation expenses, non-recurring transaction expenses, extraordinary gains and losses, gains and losses on discontinued operations, losses on debt extinguishment and includes cash distributions received from affiliates, plus pro-rata earnings from material acquisitions. The facility also includes a minimum current ratio covenant of no less than 1.00 to 1.00, measured quarterly. The minimum current ratio is calculated as the ratio of current assets, plus revolver availability, to current liabilities, excluding borrowings under the revolver. This calculation also excludes all of CNXC's current assets, current liabilities and revolver availability. The current ratio was 2.59 to 1.00 at December 31, 2016. Affirmative and negative covenants in the facility limit the Company's ability to dispose of assets, make investments, purchase or redeem CONSOL Energy common stock, pay dividends, merge with another corporation and amend, modify or restate the senior unsecured notes. The credit facility allows unlimited investments in joint ventures for the development and operation of natural gas gathering systems. The facility permits CONSOL Energy to separate its natural gas and coal businesses if the leverage ratio (which, is essentially the ratio of debt to EBITDA) of the natural gas business immediately after the separation would not be greater than 2.75 to 1.00. At December 31, 2016, the facility had $326 million letters of credit outstanding and no outstanding borrowings, leaving $1,674 million of unused capacity. From time to time, CONSOL Energy is required to post financial assurances to satisfy contractual and other requirements generated in the normal course of business. Some of these assurances are posted to comply with federal, state or other government agencies' statutes and regulations. CONSOL Energy sometimes uses letters of credit to satisfy these requirements and these letters of credit reduce the Company's borrowing facility capacity.

In April 2016, the facility was amended to require the Company to: (i) prepay outstanding loans under the revolving credit facility to the extent that cash on hand exceeds $150 million for two consecutive business days; (ii) mortgage 85% of its proved reserves and 80% of its proved developed producing reserves, in each case, which are included in the borrowing base; (iii) maintain applicable deposit, securities and commodities accounts with the lenders or affiliates thereof; and (iv) enter into control agreements with respect to such applicable accounts. In addition, the Company pledged the equity interest it holds in CONE Gathering, LLC, and CONE Midstream Partners, LP as collateral to secure loans under the credit agreement.

CONSOL Energy terminated its accounts receivable securitization facility effective July 7, 2015. The outstanding borrowings were repaid, and the outstanding letters of credit were transferred against the revolving credit facility.

Uncertainty in the financial markets brings additional potential risks to CONSOL Energy. These risks include declines in the Company's stock price, less availability and higher costs of additional credit, potential counterparty defaults, and commercial bank failures. Financial market disruptions may impact the Company's collection of trade receivables. As a result, CONSOL Energy regularly monitors the creditworthiness of its customers and counterparties and manages credit exposure through payment terms, credit limits, prepayments and security. CONSOL Energy believes that its current group of customers is financially sound and represents no abnormal business risk.

CONSOL Energy believes that cash generated from operations, asset sales and the Company's borrowing capacity will be sufficient to meet the Company's working capital requirements, anticipated capital expenditures (other than major acquisitions), scheduled debt payments, anticipated dividend payments and to provide required letters of credit. Nevertheless, the ability of CONSOL Energy to satisfy its working capital requirements, to service its debt obligations, to fund planned capital expenditures, or to pay dividends will depend upon future operating performance, which will be affected by prevailing economic conditions in the natural gas and coal industries and other financial and business factors, some of which are beyond CONSOL Energy’s control.

In order to manage the market risk exposure of volatile natural gas prices in the future, CONSOL Energy enters into various physical natural gas supply transactions with both gas marketers and end users for terms varying in length. CONSOL Energy has also entered into various natural gas and NGL swap and option transactions, which exist parallel to the underlying physical

92

transactions. The fair value of these contracts was a net liability of $188 million at December 31, 2016 and a net asset of $267 million at December 31, 2015. The Company has not experienced any issues of non-performance by derivative counterparties.

CONSOL Energy frequently evaluates potential acquisitions. CONSOL Energy has funded acquisitions with cash generated from operations and a variety of other sources, depending on the size of the transaction, including debt and equity financing. There can be no assurance that additional capital resources, including debt and equity financing, will be available to CONSOL Energy on terms which CONSOL Energy finds acceptable, or at all.

Cash Flows (in millions)

	For the Years Ended December 31,
	2016			2015			Change
Cash provided by operating activities	$	469		$	506		$	(37	)
Cash provided by (used in) investing activities	$	487		$	(996	)	$	1,483
Cash (used in) provided by financing activities	$	(969	)	$	386		$	(1,355	)

Cash provided by operating activities changed in the period-to-period comparison primarily due to the following items:

• Net loss increased $475 million in the period-to-period comparison.

• Adjustments to reconcile net income to cash provided by operating activities decreased $829 million due to the impairment of exploration and production properties recorded in 2015. (See Note 9 - Property, Plant, And Equipment, in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for more information). This adjustment was offset by an increase in the (gain) loss on commodity derivative instruments of $534 million, a net change in discontinued operations of $293 million (See Note 2 - Discontinued Operations in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for more information), an increase of $262 million in other post-employee benefits plan amendments recorded in 2015, and an increase of $261 million related to changes in deferred taxes.

• Other changes in operating assets, operating liabilities, other assets and other liabilities which occurred throughout both periods also contributed to the decrease in operating cash flows.

Cash provided by (used in) investing activities changed in the period-to-period comparison primarily due to the following items:

• Capital expenditures decreased $756 million in the period-to-period comparison due to the following:

◦ E&P division capital expenditures decreased $667 million due to decreased expenditures in both the Marcellus and Utica plays resulting from decreased drilling activity, as well as other various transactions that occurred throughout both periods none of which were individually material.

◦ PA Mining Operations division capital expenditures decreased $85 million primarily due to a $37 million decrease in equipment purchases and rebuilds, a $25 million decrease in land project expenditures, and various other items that occurred throughout both periods, none of which were individually material.

◦ Other capital expenditures decreased $4 million due to various transactions that occurred throughout both periods, none of which were individually material.

• Proceeds from the sale of assets increased $163 million primarily due to the $213 million received in December 2016 related to the separation of the Marcellus Shale Joint Venture with Noble Energy. This was offset, in part, by the $76 million received in September 2015 related to the sale of CONSOL Energy's interest in its Western Allegheny Energy joint venture. See Note 3 - Acquisitions and Dispositions in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional details. The remaining change was due to various land and equipment asset sales that occurred throughout both periods, none of which were individually material.

• Net investment in equity affiliates changed $158 million in the period-to-period comparison due to $70 million received in November 2016 in connection with equity affiliate CONE Midstream Partners, LP acquiring an additional 25% interest in CONE Midstream DevCo I LP, commonly referred to as the "Anchor Systems" (See Note 25 - Related Party Transactions in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information), as well as the sale of the Company's 49% interest in Western Allegheny Energy in September 2015 discussed above.

• Discontinued Operations increased $407 million primarily as a result of the sale of the Buchanan Mine and certain other metallurgical coal reserves and the sale of the Miller Creek and Fola mining complexes in the year ended December

93

31, 2016. (See Note 2 - Discontinued Operations in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information).

Cash (used in) provided by financing activities changed in the period-to-period comparison primarily due to the following items:

• In the year ended December 31, 2016, CONSOL Energy made payments on the senior secured credit facility of $952 million compared to proceeds from the senior secured credit facility of $952 million in the year ended December 31, 2015.

• In the year ended December 31, 2015, CONSOL Energy made net payments of $771 million related to the partial extinguishment of the 2020 and 2021 bonds offset, in part, by the issuance of the 2023 bonds. No such transactions occurred in the 2016 period. (See Note 12 - Long-Term Debt in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional details).

• In the year ended December 31, 2016, there were $16 million of net proceeds under the CNX Coal Resources LP credit facility, compared with $185 million in the year ended December 31, 2015.

• In the year ended December 31, 2015, CONSOL Energy received proceeds of $148 million from the IPO of CNX Coal Resources LP. No such transaction occurred in the 2016 period.

• In the year ended December 31, 2015, CONSOL Energy repurchased $72 million of its common stock on the open market under the previously announced share repurchase program. No repurchases were made in the year ended December 31, 2016.

• The remaining changes are due to various transactions that occurred throughout both periods.

The following is a summary of our significant contractual obligations at December 31, 2016 (in thousands):

	Payments due by Year
	Less Than 1 Year		1-3 Years		3-5 Years		More Than 5 Years		Total

 _________________________

(a) Employee related long-term liabilities include other post-employment benefits, work-related injuries and illnesses. Estimated salaried retirement contributions required to meet minimum funding standards under ERISA are excluded from the pay-out table due to the uncertainty regarding amounts to be contributed. CONSOL Energy does not expect to contribute to the pension in 2017.

(b) Other long-term liabilities include mine reclamation and closure and other long-term liability costs.

(c) The significant obligation table does not include obligations to taxing authorities due to the uncertainty surrounding the ultimate settlement of amounts and timing of these obligations.

94

Debt

At December 31, 2016, CONSOL Energy had total long-term debt and capital lease obligations of $2,802 million outstanding, including the current portion of long-term debt of $12 million. This long-term debt consisted of:

• An aggregate principal amount of $74 million of 8.25% senior unsecured notes due in April 2020. Interest on the notes is payable April 1 and October 1 of each year. Payment of the principal and interest on the notes is guaranteed by most of CONSOL Energy’s subsidiaries.

• An aggregate principal amount of $21 million of 6.375% senior unsecured notes due in March 2021. Interest on the notes is payable March 1 and September 1 of each year. Payment of the principal and interest on the notes is guaranteed by most of CONSOL Energy's subsidiaries.

• An aggregate principal amount of $1,850 million of 5.875% senior unsecured notes due in April 2022 plus $5 million of unamortized bond premium. Interest on the notes is payable April 15 and October 15 of each year. Payment of the principal and interest on the notes is guaranteed by most of CONSOL Energy's subsidiaries.

• An aggregate principal amount of $500 million of 8.00% senior unsecured notes due in April 2023 less $6 million of unamortized bond discount. Interest on the notes is payable April 1 and October 1 of each year. Payment of the principal and interest on the notes is guaranteed by most of CONSOL Energy's subsidiaries.

• An aggregate principal amount of $103 million of industrial revenue bonds which were issued to finance the Baltimore port facility and bear interest at 5.75% per annum and mature in September 2025. Interest on the industrial revenue bonds is payable March 1 and September 1 of each year. Payment of the principal and interest on the notes is guaranteed by CONSOL Energy.

• Advance royalty commitments of $3 million with an average interest rate of 7.73% per annum.

• An aggregate principal amount of $2 million on a note maturing through March 2018.

• An aggregate principal amount of $49 million of capital leases with a weighted average interest rate of 6.45% per annum.

• An aggregate principal amount of $201 million in outstanding borrowings under the revolver for CNXC. CONSOL Energy is not a guarantor of CNXC's revolving credit facility.

At December 31, 2016, CONSOL Energy had no borrowings outstanding and approximately $326 million of letters of credit outstanding under the $2 billion senior secured revolving credit facility.

Total Equity and Dividends

CONSOL Energy had total equity of $3,941 million at December 31, 2016 compared to $4,856 million at December 31, 2015. See the Consolidated Statements of Stockholders' Equity in Item 8 of this Form 10-K for additional details.

Dividend information for the current year to date is as follows:

Declaration Date	Amount Per Share	Record Date	Payment Date
February 1, 2016	$0.0100	February 16, 2016	March 3, 2016

The declaration and payment of dividends by CONSOL Energy is subject to the discretion of CONSOL Energy’s Board of Directors, and no assurance can be given that CONSOL Energy will pay dividends in the future. CONSOL Energy’s Board of Directors determines whether dividends will be paid quarterly. CONSOL Energy suspended its quarterly dividend following the sale of the Buchanan Mine on March 31, 2016 to further reflect the Company's increased emphasis on growth. The determination to pay dividends in the future will depend upon, among other things, general business conditions, CONSOL Energy’s financial results, contractual and legal restrictions regarding the payment of dividends by CONSOL Energy, planned investments by CONSOL Energy and such other factors as the Board of Directors deems relevant. The Company's credit facility limits CONSOL Energy's ability to pay dividends in excess of an annual rate of $0.50 per share when the Company's leverage ratio exceeds 3.50 to 1.00 and subject to an aggregate amount up to a cumulative credit calculation set forth in the facility. The total leverage ratio was 4.53 to 1.00 and the cumulative credit was approximately $781 million at December 31, 2016. The calculation of this leverage ratio excludes CNXC. The credit facility does not permit dividend payments in the event of default. The indentures to the 2022 and 2023 notes limit dividends to $0.50 per share annually unless several conditions are met. These conditions include no defaults, ability to incur additional debt and other payment limitations under the indentures. There were no defaults in the year ended December 31, 2016.

On January 20, 2017 the Board of Directors of CONE Midstream GP LLC, the general partner of CONE Midstream Partners LP, announced the declaration of a cash distribution of $0.2724 per unit with respect to the fourth quarter of 2016. The distribution will be made on February 14, 2017 to unitholders of record as of the close of business on February 6, 2017. The distribution, which equates to an annual rate of $1.0896 per unit, represents an increase of 3.6% over the prior quarter, and an increase of 15.3% over the distribution paid with respect to the fourth quarter of 2015.

95

On January 24, 2017, the Board of Directors of CNXC declared a cash distribution of $0.5125 per unit to all common and subordinated partner unitholders, including the holder of the general partner interest, and $0.4678 per preferred unit. The cash distribution will be made on February 15, 2017 to such holders of record at the close of business on February 9, 2017.

Off-Balance Sheet Transactions

CONSOL Energy does not maintain off-balance sheet transactions, arrangements, obligations or other relationships with unconsolidated entities or others that are reasonably likely to have a material current or future effect on CONSOL Energy’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources which are not disclosed in the Notes to the Audited Consolidated Financial Statements. CONSOL Energy participates in the UMWA Combined Benefit Fund and the UMWA 1992 Benefit Plan which generally accepted accounting principles recognize on a pay as you go basis. These benefit arrangements may result in additional liabilities that are not recognized on the balance sheet at December 31, 2016. The various multi-employer benefit plans are discussed in Note 16—Other Employee Benefit Plans in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K. CONSOL Energy also uses a combination of surety bonds, corporate guarantees and letters of credit to secure our financial obligations for employee-related, environmental, performance and various other items which are not reflected on the balance sheet at December 31, 2016. Management believes these items will expire without being funded. See Note 22—Commitments and Contingencies in the Notes to the Audited Consolidated Financial Statements included in Item 8 of this Form 10-K for additional details of the various financial guarantees that have been issued by CONSOL Energy.

Recent Accounting Pronouncements

In January 2017, the FASB issued Update 2017-01 - Business Combinations (Topic 805). This update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this new guidance is not expected to have a material impact on CONSOL Energy's financial statements.

In December 2016, the FASB issued Update 2016-19 - Technical Corrections and Improvements, which covers a wide range of Topics in the Accounting Standards Codification (ASC). The amendments in this Update represent changes to clarify, correct errors, or make minor improvements to the ASC, making it easier to understand and apply by eliminating inconsistencies and providing clarifications. The amendments generally fall into one of the following categories: amendments related to differences between original guidance and the ASC, guidance clarification and reference corrections, simplification, or minor improvements. Most of the amendments in this Update do not require transition guidance and are effective upon issuance of this Update.

In October 2016, the FASB issued Update 2016-17 - Consolidation (Topic 810): Interests Held through Related Parties that are Under Common Control, which amends the consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity (VIE) should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The Update requires the reporting entity, in determining whether it satisfies the second characteristic of a primary beneficiary, to include its indirect variable interests in a VIE held through related parties that are under common control on a proportionate basis as opposed to in their entirety. The amendments in this Update will be applied retrospectively and are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The adoption of this new guidance is not expected to have a material impact on CONSOL Energy's financial statements.

In August 2016, the FASB issued Update 2016-15 - Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments relate to debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, distributions received from equity method investees, and beneficial interests in securitization transactions. The Update also states that, in the absence of specific guidance for cash receipts and payments that have aspects of more than one class of cash flows, an entity should classify each separately identifiable source or use within the cash receipts and payments on the basis of their nature in financing, investing, or operating activities. In situations in which cash receipts or payments cannot be separated by source or use, the appropriate classification should depend on the activity that is likely to be the predominant source or use of cash flows for the item. The amendments in the Update will be applied using a retrospective transition method to each period presented and, for public entities, are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact this guidance may have on CONSOL Energy's financial statements.

96

In June 2016, the FASB issued Update 2016-13 - Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which provides financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this, the amendments in this Update replace the incurred loss impairment methodology in current Generally Accepted Accounting Principals (GAAP) with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The measurement of expected credit losses will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The amendments in this Update will be applied using a modified-retrospective approach and, for public entities, are effective for fiscal years beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted for fiscal years beginning after December 15, 2018 and interim periods within those annual periods. The Company believes this guidance will not have a material impact on CONSOL Energy's financial statements.

In May 2014, the FASB issued Update 2014-09 - Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Topic 605 - Revenue Recognition and most industry-specific guidance throughout the Industry Topics of the Codification. The objective of the amendments in this Update is to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards (IFRS). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and should disclose sufficient information, both qualitative and quantitative, to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The following updates to Topic 606 were made during 2016:

• In March 2016, the FASB issued Update 2016-08 - Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies how an entity determines whether it is a principal or an agent for goods or services promised to a customer as well as the nature of the goods or services promised to their customers.

• In April 2016, the FASB issued Update 2016-10 - Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing, which seeks to address implementation issues in the areas of identifying performance obligations and licensing.

• In May 2016, the FASB issued Update 2016-12 - Revenue from Contracts with Customers: Narrow Scope Improvements and Practical Expedients, which seeks to address implementation issues in the areas of collectibility, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition.

• In December 2016, the FASB issued Update 2016-20 - Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which includes amendments related to loan guarantee fees, contract costs, provisions for losses on construction and production-type contracts, scope, disclosures, contract modification, contract asset versus receivable, refund liability and advertising costs.

The new standards are effective for annual reporting periods beginning after December 15, 2017, with the option to adopt as early as annual reporting periods beginning after December 15, 2016. Management continues to evaluate the impacts that these standards will have on CONSOL Energy's financial statements, specifically as it relates to contracts that contain positive electric power price related adjustments. CONSOL Energy anticipates using the modified retrospective approach at adoption as it relates to ASU 2014-09.

In March 2016, the FASB issued Update 2016-09 - Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Specifically, this Update states that: all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit in the income statement; excess tax benefits should be classified along with other income tax cash flows as an operating activity; an entity can make an accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur; the threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions; and cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. For public entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted. The adoption of this new guidance is not expected to have a material impact on CONSOL Energy's financial statements.

In February 2016, the FASB issued Update 2016-02 - Leases (Topic 842), which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Update 2016-02 does retain a distinction between finance leases and operating leases, which is substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the previous lease guidance.

97

Retaining this distinction allows the recognition, measurement and presentation of expenses and cash flows arising from a lease to not significantly change from previous GAAP. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities, but to recognize lease expense on a straight-line basis over the lease term. For both financing and operating leases, the right-to-use asset and lease liability will be initially measured at the present value of the lease payments in the statement of financial position.The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact this guidance may have on CONSOL Energy's financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

In addition to the risks inherent in operations, CONSOL Energy is exposed to financial, market, political and economic risks. The following discussion provides additional detail regarding CONSOL Energy's exposure to the risks of changing commodity prices, interest rates and foreign exchange rates.

CONSOL Energy is exposed to market price risk in the normal course of selling natural gas and to a lesser extent in the sale of coal. CONSOL Energy uses fixed-price contracts, options and derivative commodity instruments to minimize exposure to market price volatility in the sale of natural gas and NGLs. CONSOL Energy sells coal under both short-term and long-term contracts with fixed price and/or indexed price contracts that reflect market value. Under our risk management policy, it is not our intent to engage in derivative activities for speculative purposes.

CONSOL Energy has established risk management policies and procedures to strengthen the internal control environment of the marketing of commodities produced from its asset base. All of the derivative instruments without other risk assessment procedures are held for purposes other than trading. They are used primarily to mitigate uncertainty, volatility and cover underlying exposures. CONSOL Energy's market risk strategy incorporates fundamental risk management tools to assess market price risk and establish a framework in which management can maintain a portfolio of transactions within pre-defined risk parameters.

CONSOL Energy believes that the use of derivative instruments, along with our risk assessment procedures and internal controls, mitigates our exposure to material risks. However, the use of derivative instruments without other risk assessment procedures could materially affect CONSOL Energy's results of operations depending on market prices. Nevertheless, we believe that use of these instruments will not have a material adverse effect on our financial position or liquidity.

For a summary of accounting policies related to derivative instruments, see Note 1—Significant Accounting Policies in the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K.

At December 31, 2016, our open derivative instruments were in a net liability position with a fair value of $188 million. A sensitivity analysis has been performed to determine the incremental effect on future earnings related to open derivative instruments at December 31, 2016. A hypothetical 10 percent increase in future natural gas prices would decrease future earnings related to derivatives by $253 million.

CONSOL Energy's interest expense is sensitive to changes in the general level of interest rates in the United States. At December 31, 2016, CONSOL Energy had $2,573 million aggregate principal amount of debt outstanding under fixed-rate instruments and $201 million of debt outstanding under variable-rate instruments. CONSOL Energy's primary exposure to market risk for changes in interest rates relates to our revolving credit facility, under which there were no borrowings at December 31, 2016, and CNXC's revolving credit facility, under which there were $201 million of borrowings at December 31, 2016. A hypothetical 100 basis-point increase in the average rate for CONSOL Energy's and CNXC's revolving credit facilities would decrease pre-tax future earnings related to interest expense by $2 million.

Almost all of CONSOL Energy’s transactions are denominated in U.S. dollars, and, as a result, it does not have material exposure to currency exchange-rate risks.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of CONSOL Energy Inc. and Subsidiaries

We have audited the accompanying consolidated balance sheets of CONSOL Energy Inc. and Subsidiaries as of December 31, 2016 and 2015, and the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2016. Our audits also included the financial statement schedule listed in the index at Item 15(a). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of CONSOL Energy Inc. and Subsidiaries at December 31, 2016 and 2015, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2016, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), CONSOL Energy Inc. and Subsidiaries' internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 8, 2017 expressed an unqualified opinion thereon.

CONSOL ENERGY INC. AND SUBSIDIARIES

NOTES TO AUDITED CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands, except per share data)

NOTE 1—SIGNIFICANT ACCOUNTING POLICIES:

A summary of the significant accounting policies of CONSOL Energy Inc. and subsidiaries ("CONSOL Energy" or "the Company") is presented below. These, together with the other notes that follow, are an integral part of the Consolidated Financial Statements.

Basis of Consolidation:

The Consolidated Financial Statements include the accounts of CONSOL Energy Inc, and its wholly owned and majority-owned and/or controlled subsidiaries, including certain variable interest entities that the Company is required to consolidate pursuant to the Consolidated topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification. The portion of these entities that is not owned by the Company is presented as non-controlling interest. Investments in business entities in which CONSOL Energy does not have control, but has the ability to exercise significant influence over the operating and financial policies, are accounted for under the equity method. All significant intercompany transactions and accounts have been eliminated in consolidation. Investments in oil and natural gas producing entities are accounted for under the proportionate consolidation method.

Discontinued Operations:

Businesses divested are classified in the Consolidated Financial Statements as either discontinued operations or held for sale when the provision of Accounting Standards Codification (ASC) Topic 205 or ASC Topic 360 are met. For businesses classified as discontinued operations, the balance sheet amounts and results of operations are reclassified from their historical presentation to assets and liabilities of discontinued operations on the Consolidated Balance Sheets and to discontinued operations on the Consolidated Statements of Income and Cash Flows for all periods presented. The gains or losses associated with these divested businesses are recorded in discontinued operations on the Consolidated Statements of Income. The disclosures outside of Note 2- Discontinued Operations, for all periods presented, in the accompanying notes generally do not include the assets, liabilities, or operating results of businesses classified as discontinued operations.

Use of Estimates:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as various disclosures. Actual results could differ from those estimates. The most significant estimates included in the preparation of the consolidated financial statements are related to other postretirement benefits, coal workers' pneumoconiosis, workers' compensation, salary retirement benefits, stock-based compensation, asset retirement obligations, deferred income tax assets and liabilities, contingencies and the values of coal and natural gas, NGLs, condensate and oil (collectively "natural gas") reserves.

Cash and Cash Equivalents:

Cash and cash equivalents include cash on hand and on deposit at banking institutions as well as all highly liquid short-term securities with original maturities of three months or less.

Trade Accounts Receivable:

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. CONSOL Energy reserves for specific accounts receivable when it is probable that all or a part of an outstanding balance will not be collected, such as customer bankruptcies. Collectability is determined based on terms of sale, credit status of customers and various other circumstances. CONSOL Energy regularly reviews collectability and establishes or adjusts the allowance as necessary using the specific identification method. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Reserves for uncollectable amounts were not material in the periods presented. In addition, there were no material financing receivables with a contractual maturity greater than one year at December 31, 2016 or 2015.

108

Inventories:

Inventories are stated at the lower of cost or net realizable value. The cost of coal inventories is determined by the first-in, first-out (FIFO) method. Coal inventory costs include labor, supplies, equipment costs, operating overhead, depreciation, depletion, amortization, and other related costs. The cost of supplies inventory is determined by the average cost method and includes operating and maintenance supplies to be used in the Company's E&P and coal operations.

Property, Plant and Equipment:

CONSOL Energy uses the successful efforts method of accounting for natural gas producing activities. Costs of property acquisitions, successful exploratory, development wells and related support equipment and facilities are capitalized. Periodic valuation provisions for impairment of capitalized costs of unproved mineral interests are expensed. Costs of unsuccessful exploratory wells are expensed when such wells are determined to be non-productive, or if the determination cannot be made after finding sufficient quantities of reserves to continue evaluating the viability of the project. The costs of producing properties and mineral interests are amortized using the units-of-production method. Wells and related equipment and intangible drilling costs are also amortized on a units-of-production method. Units-of-production amortization rates are revised at least once per year, or more frequently if events and circumstances indicate an adjustment is necessary. Such revisions are accounted for prospectively as changes in accounting estimates.

Property, plant and equipment is recorded at cost upon acquisition. Expenditures which extend the useful lives of existing plant and equipment are capitalized. Interest costs applicable to major asset additions are capitalized during the construction period. Costs of additional mine facilities required to maintain production after a mine reaches the production stage, generally referred to as “receding face costs,” are expensed as incurred; however, the costs of additional airshafts and new portals are capitalized. Planned major maintenance costs which do not extend the useful lives of existing plant and equipment are expensed as incurred.

Coal exploration costs are expensed as incurred. Coal exploration costs include those incurred to ascertain existence, location, extent or quality of ore or minerals before beginning the development stage of the mine.

Costs of developing new underground mines and certain underground expansion projects are capitalized. Underground development costs, which are costs incurred to make the mineral physically accessible, include costs to prepare property for shafts, driving main entries for ventilation, haulage, personnel, construction of airshafts, roof protection and other facilities.

Airshafts and capitalized mine development associated with a coal reserve are amortized on a units-of-production basis as the coal is produced so that each ton of coal is assigned a portion of the unamortized costs. The Company employs this method to match costs with the related revenues realized in a particular period. Rates are updated when revisions to coal reserve estimates are made. Coal reserve estimates are reviewed when information becomes available that indicates a reserve change is needed, or at a minimum once per year. Any material effect from changes in estimates is disclosed in the period the change occurs. Amortization of development cost begins when the development phase is complete and the production phase begins. At an underground mine, the end of the development phase and the beginning of the production phase takes place when construction of the mine for economic extraction is substantially complete. Coal extracted during the development phase is incidental to the mine's production capacity and is not considered to shift the mine into the production phase.

Coal reserves are controlled either through fee ownership or by lease. The duration of the leases vary; however, the lease terms are generally extended automatically through the exhaustion of economically recoverable reserves, as long as active mining continues. Coal interests held by lease provide the same rights as fee ownership for mineral extraction and are legally considered real property interests. Depletion of leased coal interests is computed using the units-of-productions method over proven and probable coal reserves. The Company also makes advance payments (advanced mining royalties) to lessors under certain lease agreements that are recoupable against future production, and it makes payments that are generally based upon a specified rate per ton or a percentage of gross realization from the sale of the coal. The Company evaluates its properties periodically for impairment issues or whenever events or circumstances indicate that the carrying amount may not be recoverable.

Gas advance royalties are similar in nature to advance mining royalties and are evaluated periodically, or at a minimum once per year, for impairment issues or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Any revisions are accounted for prospectively as changes in accounting estimates.

109

Depreciation of plant and equipment is calculated on the straight-line method over their estimated useful lives or lease terms, generally as follows:

	Years
Buildings and improvements	10 to 45
Machinery and equipment	3 to 25
Leasehold improvements	Life of Lease

Costs to obtain coal lands are capitalized based on the cost at acquisition and are amortized using the units-of-production method over all estimated proven and probable coal reserve tons assigned and accessible to the mine. Proven and probable coal reserves are calculated on a clean coal ton equivalent, which excludes non-recoverable coal reserves and anticipated preparation plant processing refuse. Rates are updated when revisions to coal reserve estimates are made. Coal reserve estimates are reviewed when events and circumstances indicate a reserve change is needed, or at a minimum once a year. Amortization of coal interests begins when the coal reserve is produced. At an underground coal mine, a ton is considered produced once it reaches the surface area of the mine. Any material effect from changes in estimates is disclosed in the period the change occurs.

Costs for purchased and internally developed software are expensed until it has been determined that the software will result in probable future economic benefits and management has committed to funding the project. Thereafter, all direct costs of materials and services incurred in developing or obtaining software, including certain payroll and benefit costs of employees associated with the project, are capitalized and amortized using the straight-line method over the estimated useful life which does not exceed seven years.

Capitalization of Interest:

Interest costs associated with the development of significant properties and projects are capitalized until the project is substantially complete and ready for its intended use. A weighted average cost of borrowing rate is used. For the years ended December 31, 2016, 2015, and 2014, capitalized interest totaled $1,467, $2,509 and $13,573, respectively.

Impairment of Long-lived Assets:

Impairment of long-lived assets is recorded when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying value. The carrying value of the assets is then reduced to its estimated fair value which is usually measured based on an estimate of future discounted cash flows. Impairment of equity investments is recorded when indicators of impairment are present and the estimated fair value of the investment is less than the assets' carrying value.

Impairment of Proved Properties

CONSOL Energy performs a quantitative annual impairment test, during the fourth quarter of each year, over proved properties using the published NYMEX forward prices, timing, methods and other assumptions consistent with historical periods. During interim periods, management updates these annual tests whenever events or changes in circumstances indicate that a property’s carrying amount may not be recoverable. Impairment tests require that the Company first compare future undiscounted cash flows by asset group to their respective carrying values. If the carrying amount exceeds the estimated undiscounted future cash flows, a reduction of the carrying amount of the natural gas properties to their estimated fair values is required, which is determined based on discounted cash flow techniques using a market-specific weighted average cost of capital. 

During the year ended December 31, 2015, certain of the Company’s proved properties, primarily shallow oil and gas assets, failed the undiscounted cash flow portion of the test. After performing the discounted cash flow portion of the test, CONSOL Energy recorded an impairment of $824,742, included in Impairment of Exploration and Production Properties in the Consolidated Statements of Income. Valuation of the impaired assets is a Level 3 measurement as it incorporates significant unobservable inputs, such as future production levels and operating costs, within the discounted cash flow analysis. The impairment related to approximately 95% of the Company’s shallow oil and gas assets in West Virginia and Pennsylvania.

There were no other additional impairments related to proved properties in the year ended December 31, 2015. There were no such impairments for the years ended December 31, 2016 or 2014.

110

Impairment of Unproved Properties

CONSOL Energy evaluates capitalized costs of unproved gas properties for recoverability on a prospective basis. Indicators of potential impairment include potential shifts in business strategy, overall economic factors and historical experience. If it is determined that the properties will not yield proved reserves, the related costs are expensed in the period the determination is made. For the year ended December 31, 2015, unproved property impairments relating to the determination that the properties will not yield proved reserves were $4,163 and are included in Impairment of Exploration and Production Properties in the Consolidated Statements of Income. Valuation of the impaired assets is a Level 3 measurement as it incorporates significant unobservable inputs, such as future production levels and operating costs, within the discounted cash flow analysis. This impairment primarily related to the court ruling in June 2015 in the state of New York that officially bans hydraulic fracturing.

There were no other additional impairments related to unproved properties in the year ended December 31, 2015. There were no such impairments for the years ended December 31, 2016 and 2014.

Exploration expense, which is associated primarily with lease expirations, was $14,519, $10,120 and $23,355 for the years ended December 31, 2016, 2015 and 2014, respectively, and is included in Exploration and Production Related Other Costs in the Consolidated Statements of Income.

Income Taxes:

Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in CONSOL Energy's financial statements or tax returns. The provision for income taxes represents income taxes paid or payable for the current year and the change in deferred taxes, excluding the effects of acquisitions during the year. Deferred taxes result from differences between the financial and tax bases of CONSOL Energy's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a deferred tax benefit will not be realized.

CONSOL Energy evaluates all tax positions taken on the state and federal tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that do not meet the more likely than not to be sustained criteria, the Company determines, on a cumulative probability basis, the largest amount of benefit that is more likely than not to be realized upon ultimate settlement. A previously recognized tax position is reversed when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the probable amount that is more likely than not is based on judgment, historical experience and on various other assumptions that the Company believes are reasonable under the circumstances. The results of these estimates, that are not readily apparent from other sources, form the basis for recognizing an uncertain tax position liability. Actual results could differ from those estimates upon subsequent resolution of identified matters.

Postretirement Benefits Other Than Pensions:

Postretirement benefit obligations established by the Coal Industry Retiree Health Benefit Act of 1992 (the Coal Act) are treated as a multi-employer plan which requires expense to be recorded for the associated obligations as payments are made. Postretirement benefits other than pensions, except for those established pursuant to the Coal Act, are accounted for in accordance with the Retirement Benefits Compensation and Non-retirement Postemployment Benefits Compensation Topics of the FASB Accounting Standards Codification, which requires employers to accrue the cost of such retirement benefits for the employees' active service periods. Such liabilities are determined on an actuarial basis and CONSOL Energy is primarily self-insured for these benefits. Differences between actual and expected results or changes in the value of obligations are recognized through Other Comprehensive Income.

Pneumoconiosis Benefits and Workers' Compensation:

CONSOL Energy is required by federal and state statutes to provide benefits to certain current and former totally disabled employees or their dependents for awards related to coal workers' pneumoconiosis. CONSOL Energy is also required by various state statutes to provide workers' compensation benefits for employees who sustain employment-related physical injuries or some types of occupational disease. Workers' compensation benefits include compensation for their disability, medical costs, and on some occasions, the cost of rehabilitation. CONSOL Energy is primarily self-insured for these benefits. Provisions for estimated benefits are determined on an actuarial basis.

111

Gas Well Closing and Mine Closing Costs:

CONSOL Energy accrues for dismantling and removing costs of gas-related facilities, mine closing costs, perpetual water care costs, and surface reclamation using the accounting treatment prescribed by the Asset Retirement and Environmental Obligations Topic of the FASB Accounting Standards Codification. This topic requires the fair value of an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. Accrued costs of dismantling and removing natural gas-related facilities, mine closing costs (including surface reclamation costs) and perpetual care costs are regularly reviewed by management and are revised for changes in future estimated costs and regulatory requirements. The present value of the estimated asset retirement costs is capitalized as part of the carrying amount of the long-lived asset. Amortization of the capitalized asset retirement cost is generally determined on a units-of-production basis. Accretion of the asset retirement obligation is recognized over time and generally will escalate over the life of the producing asset, typically as production declines. Accretion is included in Deprecation, Depletion and Amortization on the Consolidated Statements of Income. Asset retirement obligations primarily relate to the closure of natural gas wells and coal mines, which includes treatment of water and the reclamation of land upon exhaustion of coal and natural gas reserves.

Subsidence:

Subsidence occurs when there is sinking or shifting of the ground surface due to the removal of underlying coal. Areas affected may include, although are not limited to, streams, property, roads, pipelines and other land and surface structures. Total estimated subsidence claims are recognized in the period when the related coal has been extracted and are included in Operating and Other Costs on the Consolidated Statements of Income and Other Accrued Liabilities on the Consolidated Balance Sheets. On occasion, CONSOL Energy prepays the estimated damages prior to undermining the property, in return for a release of liability. Prepayments are included as assets and either recognized as Prepaid Expenses or in Other Assets on the Consolidated Balance Sheets if the payment is made less than or greater than one year, respectively, prior to undermining the property.

Retirement Plans:

CONSOL Energy has non-contributory defined benefit retirement plans. Effective December 31, 2015, CONSOL's qualified defined benefit retirement plans have been frozen. The benefits for these plans are based primarily on years of service and employees' pay. These plans are accounted for using the guidance outlined in the Compensation - Retirement Benefits Topic of the FASB Accounting Standards Codification. The cost of these retiree benefits are recognized over the employees' service periods. CONSOL Energy uses actuarial methods and assumptions in the valuation of defined benefit obligations and the determination of expense. Differences between actual and expected results or changes in the value of obligations and plan assets are recognized through Other Comprehensive Income.

Revenue Recognition:

Revenues are recognized when title passes to the customers. For natural gas, NGL and oil sales, this occurs at the contractual point of delivery. For domestic coal sales, this generally occurs when coal is loaded at the mine, the preparation facility, or offsite storage locations. For export coal sales, this generally occurs when coal is loaded onto marine vessels at terminal locations. For terminal, land, and research and development, revenue is recognized generally as the service is provided to the customer.

CONSOL Energy has operational natural gas-balancing agreements. These imbalance agreements are managed internally using the sales method of accounting. The sales method recognizes revenue when the gas is taken by the purchaser.

CONSOL Energy sells natural gas to accommodate the delivery points of its customers. In general, this gas is purchased at market price and re-sold on the same day at market price less a small transaction fee. These matching buy/sell transactions include a legal right of offset of obligations and have been simultaneously entered into with the counterparty. These transactions qualify for netting under the Nonmonetary Transactions Topic of the FASB Accounting Standards Codification and are, therefore, recorded net within the Consolidated Statements of Income in the Purchased Gas Sales line.

CONSOL Energy purchases natural gas produced by third-parties at market prices less a fee. The gas purchased from third-parties is then resold to end users or gas marketers at current market prices. These revenues and expenses are recorded gross as Purchased Gas Sales in the Consolidated Statements of Income. Purchased gas sales are recognized when title passes to the customer. Purchased gas costs are recognized when title passes to CONSOL Energy from the third-party.

112

Freight Revenue and Expense:

Shipping and handling costs invoiced to coal customers and paid to third-party carriers are recorded as Freight-Outside Coal revenue and Freight Expense, respectively.

Contingencies:

From time to time, CONSOL Energy, or its subsidiaries, is subject to various lawsuits and claims with respect to such matters as personal injury, wrongful death, damage to property, exposure to hazardous substances, governmental regulations (including environmental remediation), employment and contract disputes, and other claims and actions, arising out of the normal course of business. Liabilities are recorded when it is probable that obligations have been incurred and the amounts can be reasonably estimated. Estimates are developed through consultation with legal counsel involved in the defense of these matters and are based upon the nature of the lawsuit, progress of the case in court, view of legal counsel, prior experience in similar matters and management's intended response. Environmental liabilities are not discounted or reduced by possible recoveries from third-parties. Legal fees associated with defending these various lawsuits and claims are expensed when incurred.

Stock-Based Compensation:

Stock-based compensation expense for all stock-based compensation awards is based on the grant date fair value estimated in accordance with the provisions of the Stock Compensation Topic of the FASB Accounting Standards Codification. CONSOL Energy recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is generally the award's vesting term. See Note 17–Stock-Based Compensation for more information.

Earnings per Share:

Basic earnings per share are computed by dividing net income attributable to CONSOL Energy Shareholders by the weighted average shares outstanding during the reporting period. Dilutive earnings per share are computed similarly to basic earnings per share, except that the weighted average shares outstanding are increased to include additional shares from stock options, performance stock options, restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding stock options and performance share options were exercised, that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities were used to acquire shares of common stock at the average market price during the reporting period. CONSOL Energy includes the impact of pro forma deferred tax assets in determining potential windfalls and shortfalls for purposes of calculating assumed proceeds under the treasury stock method.

The table below sets forth the share-based awards that have been excluded from the computation of the diluted earnings per share because their effect would be anti-dilutive:

Accounting for Derivative Instruments:

CONSOL Energy enters into financial derivative instruments to manage its exposure to commodity price volatility. The derivatives are accounted for as an asset or a liability in the accompanying Consolidated Balance Sheets at their fair value using “Level Two” inputs, which is further defined in Note 20 - Fair Value of Financial Instruments. Changes in the fair values of derivatives are recorded in earnings unless special hedge accounting criteria are met. For derivatives designated as cash flow hedges, the effective portions of changes in the fair values of the derivatives are reported in Other Comprehensive Income or Loss (OCI) on the Consolidated Balance Sheets, net of tax, and reclassified into Gain (Loss) on Commodity Derivative Instruments on the Consolidated Statements of Income in the same period or periods in which the forecasted transactions affect earnings. Any ineffective portion of a hedge is recognized in earnings in the current period.     

CONSOL Energy de-designated all of its cash flow hedges on December 31, 2014 and accounts for all existing and future natural gas and NGL commodity hedges on a mark-to-market basis, and records changes in fair value in current period earnings. In connection with this de-designation, CONSOL Energy froze the balances recorded in Accumulated Other Comprehensive Income at December 31, 2014 and reclassified balances to earnings as the underlying physical transactions occurred. As of December 31, 2016, all gains deferred in OCI have been recognized in earnings.

All of CONSOL Energy’s derivative instruments are subject to master netting arrangements with its counterparties, none of which currently require CONSOL Energy to post collateral for any of its hedges. However, as stated in the counterparty master agreements, if CONSOL Energy's obligations with one of its counterparties cease to be secured on the same basis as similar obligations with the other lenders under the credit facility, CONSOL Energy would be required to post collateral for hedges that are in a liability position in excess of defined thresholds. Each of CONSOL Energy's counterparty master agreements allows, in the event of default, the ability to elect early termination of outstanding contracts. If early termination is elected, CONSOL Energy and the applicable counterparty would net settle all open hedge positions.

CONSOL Energy is exposed to credit risk in the event of non-performance by counterparties, whose creditworthiness is subject to continuing review. Historically, CONSOL Energy has not experienced any issues of non-performance by derivative counterparties.

Recent Accounting Pronouncements:

In January 2017, the FASB issued Update 2017-01 - Business Combinations (Topic 805). This update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. For public business entities, the amendments in this Update are effective for

115

fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this new guidance is not expected to have a material impact on CONSOL Energy's financial statements.

In December 2016, the FASB issued Update 2016-19 - Technical Corrections and Improvements, which covers a wide range of Topics in the Accounting Standards Codification (ASC). The amendments in this Update represent changes to clarify, correct errors, or make minor improvements to the ASC, making it easier to understand and apply by eliminating inconsistencies and providing clarifications. The amendments generally fall into one of the following categories: amendments related to differences between original guidance and the ASC, guidance clarification and reference corrections, simplification, or minor improvements. Most of the amendments in this Update do not require transition guidance and are effective upon issuance of this Update.

In October 2016, the FASB issued Update 2016-17 - Consolidation (Topic 810): Interests Held through Related Parties that are Under Common Control, which amends the consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity (VIE) should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The Update requires the reporting entity, in determining whether it satisfies the second characteristic of a primary beneficiary, to include its indirect economic interests in a VIE held through related parties that are under common control on a proportionate basis as opposed to in their entirety. The amendments in this Update will be applied retrospectively and are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The adoption of this new guidance is not expected to have a material impact on CONSOL Energy's financial statements.

In August 2016, the FASB issued Update 2016-15 - Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments relate to debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, distributions received from equity method investees, and beneficial interests in securitization transactions. The Update also states that, in the absence of specific guidance for cash receipts and payments that have aspects of more than one class of cash flows, an entity should classify each separately identifiable source or use within the cash receipts and payments on the basis of their nature in financing, investing, or operating activities. In situations in which cash receipts or payments cannot be separated by source or use, the appropriate classification should depend on the activity that is likely to be the predominant source or use of cash flows for the item. The amendments in the Update will be applied using a retrospective transition method to each period presented and, for public entities, are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact this guidance may have on CONSOL Energy's financial statements.

In June 2016, the FASB issued Update 2016-13 - Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which provides financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this, the amendments in this Update replace the incurred loss impairment methodology in current Generally Accepted Accounting Principals (GAAP) with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The measurement of expected credit losses will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The amendments in this Update will be applied using a modified-retrospective approach and, for public entities, are effective for fiscal years beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted for fiscal years beginning after December 15, 2018 and interim periods within those annual periods. The Company believes this guidance will not have a material impact on CONSOL Energy's financial statements.

In May 2014, the FASB issued Update 2014-09 - Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Topic 605 - Revenue Recognition and most industry-specific guidance throughout the Industry Topics of the Codification. The objective of the amendments in this Update is to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards (IFRS). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and should disclose sufficient information, both qualitative and quantitative, to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The following updates to Topic 606 were made during 2016:

116

• In March 2016, the FASB issued Update 2016-08 - Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies how an entity determines whether it is a principal or an agent for goods or services promised to a customer as well as the nature of the goods or services promised to their customers.

• In April 2016, the FASB issued Update 2016-10 - Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing, which seeks to address implementation issues in the areas of identifying performance obligations and licensing.

• In May 2016, the FASB issued Update 2016-12 - Revenue from Contracts with Customers: Narrow Scope Improvements and Practical Expedients, which seeks to address implementation issues in the areas of collectibility, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition.

• In December 2016, the FASB issued Update 2016-20 - Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which includes amendments related to loan guarantee fees, contract costs, provisions for losses on construction and production-type contracts, scope, disclosures, contract modification, contract asset versus receivable, refund liability and advertising costs.

The new standards are effective for annual reporting periods beginning after December 15, 2017, with the option to adopt as early as annual reporting periods beginning after December 15, 2016. Management continues to evaluate the impacts that these standards will have on CONSOL Energy's financial statements, specifically as it relates to contracts that contain positive electric power price related adjustments. CONSOL Energy anticipates using the modified retrospective approach at adoption as it relates to ASU 2014-09.

In March 2016, the FASB issued Update 2016-09 - Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Specifically, this Update states that: all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit in the income statement; excess tax benefits should be classified along with other income tax cash flows as an operating activity; an entity can make an accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur; the threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions; and cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. For public entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted. The adoption of this new guidance is not expected to have a material impact on CONSOL Energy's financial statements.

In February 2016, the FASB issued Update 2016-02 - Leases (Topic 842), which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Update 2016-02 does retain a distinction between finance leases and operating leases, which is substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the previous lease guidance. Retaining this distinction allows the recognition, measurement and presentation of expenses and cash flows arising from a lease to not significantly change from previous GAAP. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities, but to recognize lease expense on a straight-line basis over the lease term. For both financing and operating leases, the right-to-use asset and lease liability will be initially measured at the present value of the lease payments in the statement of financial position.The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact this guidance may have on CONSOL Energy's financial statements.

Reclassifications:

During the year ended December 31, 2016, CONSOL Energy made reclassifications within its financial statements to better align the Company's financial reporting with its peer group. These reclassifications impacted the Lease Operating Expense, Transportation, Gathering and Compression, Direct Administrative and Selling, Production Royalty Interests and Purchased Gas Sales, Production Royalty Interests and Purchased Gas Costs, Operating and Other Costs and Selling, General and Administrative Costs line items on the Company's Consolidated Statements of Income. These changes are reflected in CONSOL Energy's current and historic Consolidated Statements of Income, with no effect on previously reported net income (loss).

117

Subsequent Events:

The Company has evaluated all subsequent events through the date the financial statements were issued. No material recognized or non-recognizable subsequent events were identified.

NOTE 2—DISCONTINUED OPERATIONS:

In August 2016, CONSOL Energy completed the sale of its Miller Creek Mining Complex and Fola Mining Complex subsidiaries. In the transaction, the buyer acquired the Miller Creek and Fola assets and assumed the Miller Creek and Fola mine closing and reclamation liabilities; in order to equalize the value exchange, CONSOL Energy paid $28,271 cash at closing, which included property taxes associated with the properties sold and other closing costs (a portion of which will be held in escrow for purposes of obtaining the surety bonds required for the the permits to transfer). These amounts were included in Net Cash Provided by Discontinued Investing Activities on the Consolidated Statements of Cash Flow. In addition, CONSOL Energy will pay a total of $17,200 in installments over the next four years. The net loss on sale of $53,130, excluding the related impairment charge discussed below, was included in Loss from Discontinued Operations, net on the Consolidated Statements of Income. Prior to the closing, the Miller Creek and Fola Mining Complexes were classified as held for sale in discontinued operations and in accordance with the accounting guidance for Property, Plant and Equipment, assets held for sale are required to be measured at the lower of the carrying value or fair value less costs to sell. Upon meeting the assets held for sale criteria, the Company determined the carrying value of the Miller Creek and Fola Mining Complexes exceeded the fair value less costs to sell. As a result, an impairment charge of $355,681 was recorded during the year ended December 31, 2016. This impairment is included in the Loss from Discontinued Operations, net on the Consolidated Statements of Income.

In March 2016, CONSOL Energy completed the sale of its membership interests in CONSOL Buchanan Mining Company, LLC (BMC), which owned and operated the Buchanan Mine located in Mavisdale, Virginia; various assets relating to the Amonate Mining Complex located in Amonate, Virginia; Russell County, Virginia coal reserves and Pangburn Shaner Fallowfield coal reserves located in Southwestern, Pennsylvania to Coronado IV LLC ("Coronado"). Various CONSOL Energy assets were excluded from the sale including coalbed methane, natural gas and minerals other than coal, current assets of BMC, certain coal seams, certain surface rights, and the Amonate Preparation Plant. Coronado assumed only specified liabilities and various CONSOL Energy liabilities were excluded and not assumed. The excluded liabilities included BMC’s indebtedness, trade payables and liabilities arising prior to closing, as well as the liabilities of the subsidiaries other than BMC which are parties to the sale. In addition, the buyer agreed to pay CONSOL Energy for Buchanan Mine coal sold outside the U.S. and Canada during the five years following closing a royalty of 20% of any excess of the gross sales price per ton over the following amounts: (1) year one, $75.00 per ton; (2) year two, $78.75 per ton; (3) year three, $82.69 per ton; (4) year four, $86.82 per ton; (5) year five, $91.16 per ton. At closing, the parties entered into several agreements including, among others, agreements relating to the coordination and conduct of gas operations at the mines, an option to purchase the Amonate Preparation Plant and transition services. Cash proceeds of $402,799 were received at closing and are included in Net Cash Provided by Discontinued Investing Activities on the Consolidated Statements of Cash Flow. The net loss on the sale was $38,364 and was included in Loss from Discontinued Operations, net on the Consolidated Statements of Income.

For all periods presented in the accompanying Consolidated Statements of Income, BMC along with the various other assets and the Miller Creek and Fola Mining Complexes are classified as discontinued operations.

NOTE 3—ACQUISITIONS AND DISPOSITIONS:

In September 2015, CONSOL Energy sold its 49% interest in Western Allegheny Energy (WAE), a joint venture with Rosebud Mining Company engaged in coal mining activities in Pennsylvania. At closing, CONSOL Energy received $76,297 in cash and a $2,136 reduction in certain liabilities. During the third quarter of 2015, CONSOL Energy also received a cash distribution of $10,780 from WAE. The net gain on the sale was $48,468 and was included in the Gain on Sale of Assets in the Consolidated Statements of Income.

In December 2014, CNX Gas Company LLC (CNX Gas Company), wholly-owned subsidiary of CONSOL Energy, finalized an agreement with Columbia Energy Ventures (CEVCO) to sublease from CEVCO approximately 20,000 acres of Utica Shale and Upper Devonian gas rights in Greene and Washington Counties in Pennsylvania and Marshall and Ohio Counties in West Virginia. Up-front bonus consideration of up to $96,106 was to be paid by CONSOL Energy over a five year period, as drilling occurs, in addition to royalties. CONSOL Energy made payments of $9,000 to CEVCO in the year ended December 31, 2016, while $50,969 of payments were made in the year ended December 31, 2015. At December 31, 2016, the amounts recorded in Other Current Liabilities and Other Long-Term Liabilities both on a discounted basis were $3,947 and $26,461, respectively. At December 31, 2015, the amounts recorded in Other Current Liabilities and Other Long-Term Liabilities on a discounted basis were $8,349 and $29,333, respectively.

In December 2014, CONSOL Energy completed the sale of its industrial supplies subsidiary to an unrelated third party for expected net proceeds of approximately $51,000, of which $44,035 was received and included in cash flows from investing activities during the year ended December 31, 2014. In connection with the sale, CONSOL Energy signed a supply agreement under which, among other things, it will continue to purchase certain goods exclusively from the new entity for a period of at least three years. CONSOL Energy recorded a net loss on the sale of $30,845, which was included in Gain on Sale of Assets in the Consolidated Statements of Income. In December 2015, there was $6,258 of expense related to the settlement of working capital adjustments and other matters in conjunction with the sale, which was included in Other Costs - Miscellaneous Operating Costs in the Consolidated Statements of Income.

NOTE 5— STOCK REPURCHASE:

In December 2014, CONSOL Energy’s Board of Directors approved a stock repurchase program under which CONSOL Energy could have purchased up to $250,000 of its common stock over a two year period. Under the terms of the program, CONSOL Energy was permitted to make repurchases in the open market, in privately negotiated transactions, accelerated repurchase programs or in structured share repurchase programs. Any repurchases of common stock were to be funded from available cash on hand or short-term borrowings. The program did not obligate CONSOL Energy to acquire any particular amount of common stock, and could have been modified or suspended at any time at the Company’s discretion. The program was conducted in compliance with applicable legal requirements and within the limits imposed by any credit agreement, receivables purchase agreement or indenture and was subject to market conditions and other factors. No shares were repurchased under this program during the year ended December 31, 2016. During the year ended December 31, 2015, 2,213,100 shares were repurchased and retired at an average price of $32.37 per share.

A valuation allowance is required when it is more likely than not that all or a portion of a deferred tax asset will not be realized. All available evidence, both positive and negative, must be considered in determining the need for a valuation allowance. For the years ended December 31, 2016 and 2015, positive evidence considered included financial earnings generated over the past three years for certain subsidiaries, reversals of financial to tax temporary differences and the implementation of and/or ability to employ various tax planning strategies. Negative evidence included financial and tax losses generated in prior periods, the inability to achieve forecasted results for those periods and the expectation that future financial results from normal operations would not be sufficient to support full utilization of certain tax credits within the foreseeable future. CONSOL Energy continues to report, on an after federal tax basis, a deferred tax asset related to state operating losses of $74,310 with a related valuation allowance of $60,488 at December 31, 2016. The deferred tax asset related to state operating losses, on an after tax adjusted basis, was $76,171 with a related valuation allowance of $42,983 at December 31, 2015. A review of positive and negative evidence regarding these tax benefits concluded that the valuation allowances for various CONSOL Energy subsidiaries was warranted. The net operating losses expire at various times between 2017 and 2036. A valuation allowance on foreign tax credits of $39,850 and $25,903 has been recorded at December 31, 2016 and 2015, respectively. The foreign tax credits expire at various times between 2021 and 2023. A valuation allowance on charitable contribution carry-forwards of $5,051 has been recorded for 2016. The charitable contributions carry-forwards expire at various times between 2018 and 2021. No such valuation allowance was recorded for 2015.

The deferred tax assets attributable to the state tax effect of future deductible temporary differences for certain CONSOL Energy subsidiaries with histories of financial and tax losses were also reviewed for positive and negative evidence regarding the realization of the deferred tax assets. A valuation allowance of $10,591 and $9,420 on an after federal tax adjusted basis has also been recorded for 2016 and 2015, respectively.

During 2016, the deferred tax asset relating to federal alternative minimum tax credits increased $76,750, to $219,872 at December 31, 2016 from $143,122 at December 31, 2015. This increase was primarily attributable to restoring previously monetized alternative minimum tax credits. This restoration was created by an agreement reached with the IRS to accelerate certain tax depreciation deductions in exchange for forgoing previously claimed alternative minimum tax credit monetization. At December 31, 2016, a valuation allowance of $166,798 was recorded against these alternative minimum tax credits, based on management's view that negative evidence with respect to their realizability outweighed positive evidence. There was no such valuation allowance at December 31, 2015. These credits do not expire and will be able to be fully utilized when sufficient operating income is generated by the Company.

Management will continue to assess the potential for realized deferred tax assets based upon income forecast data and the feasibility of future tax planning strategies and may record adjustments to valuation allowances against deferred tax assets in future periods, as appropriate, that could materially impact net income.

The following is a reconciliation, stated as a percentage of pretax income, of the United States statutory federal income tax rate to CONSOL Energy's effective tax rate:

	For the Years Ended December 31,

As part of CONSOL Energy's IRS examination of the tax years 2010-2013, bonus depreciation was claimed resulting in a net cash refund of $92,000. The bonus depreciation deduction adversely impacts earnings by reducing the Company's percentage depletion adjustment on its mining operations and reducing the Section 199 manufacturing deduction in the years 2008-2012. This

122

resulted in a net non-cash charge to earnings of $36,619.

A reconciliation of the beginning and ending gross amounts of unrecognized tax benefits is as follows:

	For the Years Ended
	December 31,
	2016			2015
Balance at beginning of period	$	12,702		$	4,265
Increase in unrecognized tax benefits resulting from tax positions taken during current period	666			—
Increase in unrecognized tax benefits resulting from tax positions taken during prior periods	—			8,437
Reduction of unrecognized tax benefits as a result of a settlement with taxing authorities	(4,265		)	—
Balance at end of period	$	9,103		$	12,702

If these unrecognized tax benefits were recognized, $666 and $4,265 would affect CONSOL Energy's effective income tax rate for 2016 and 2015, respectively.

CONSOL Energy and its subsidiaries file income tax returns in the United States and returns within various states and Canadian jurisdictions. With few exceptions, the Company is no longer subject to United States federal, state, local or non-U.S. income tax examinations by tax authorities for the years before 2010.

CONSOL Energy recognizes interest accrued related to unrecognized tax benefits in its interest expense. As of December 31, 2016 and 2015, the Company had an accrued liability of $305 and $53, respectively, for interest related to uncertain tax positions. Interest expense of $252 and $53 was recorded in the Company's Consolidated Statements of Income for the years ended December 31, 2016 and 2015, respectively. During the years ended December 31, 2016 and 2015, CONSOL Energy paid no interest related to income tax deficiencies.

CONSOL Energy recognizes penalties accrued related to uncertain tax positions in its income tax expense. As of December 31, 2016 and 2015, CONSOL Energy had no accrued liabilities for tax penalties.

NOTE 7—GAS WELL CLOSING and MINE CLOSING:

CONSOL Energy accrues for dismantling and removing costs of natural gas related facilities, mine closing costs, perpetual water care costs, and surface reclamation using the accounting treatment prescribed by the Asset Retirement and Environmental Obligations Topic of the FASB Accounting Standards Codification. CONSOL Energy recognizes capitalized asset retirement costs by increasing the carrying amount of related long-lived assets. The obligation for asset retirements is included in Gas Well Closing, Mine Closing and Other Accrued Liabilities on the Consolidated Balance Sheets.

The reconciliation of changes in the asset retirement obligations at December 31, 2016 and 2015 is as follows:

	As of December 31,
	2016			2015
Balance at beginning of period	$	429,967		$	454,832
Accretion expense	23,924			32,438
Payments	(15,882		)	(18,033		)

Other	(785		)	(5,286		)
Balance at end of period	$	473,544		$	429,967

For the year ended December 31, 2015, Other includes ($2,133) related to the disposition of two Perpetual Care sites as part of the WAE sale (see Note 3 - Acquisitions and Dispositions for more information) and ($2,355) related to the disposition of a non-producing mine.

Industry Participation Agreements

CONSOL Energy had two significant industry participation agreements (referred to as "joint ventures" or "JVs") that provided drilling and completion carries for the Company's retained interests.

CNX Gas Company is party to a joint development agreement with Hess Ohio Developments, LLC (Hess) with respect to approximately 155 thousand net Utica Shale acres in Ohio in which each party has a 50% undivided interest. Under the agreement, as amended, Hess was obligated to pay a total of approximately $335,000 in the form of a 50% drilling carry of certain CONSOL Energy working interest obligations as the acreage is developed. As of December 31, 2016, Hess' entire carry obligation has been met.

CNX Gas Company was party to a joint development agreement with Noble Energy, Inc. (Noble) with respect to approximately 700 thousand net Marcellus Shale oil and gas acres in West Virginia and Pennsylvania, in which each party owned a 50% undivided interest. On October 29, 2016, CNX Gas entered into an Exchange Agreement with Noble Energy, which terminated the joint development agreement related to the jointly owned gas assets held in connection with the joint venture with Noble and divided such jointly owned gas assets among CNX Gas and Noble Energy. The transactions contemplated by the Exchange Agreement was closed on December 1, 2016 with an effective date of October 1, 2016. As part of the exchange: each party will own and operate a 100% interest in its properties and wells in two separate operating areas; each party will have independent control and flexibility with respect to the scope and timing of future development over its operating area; and all acreage operated by CONSOL Energy and Noble Energy, Inc. in their respective operating areas will remain fully dedicated to CONE Midstream Partners LP. Cash proceeds of approximately $213,295 were received at closing and are included in cash flows from investing activities in the Consolidated Statements of Cash Flows. The exchange was accounted for as a mineral conveyance, thus no gain or loss was recorded in connection with the transaction.

NOTE 10—SHORT-TERM NOTES PAYABLE:

CONSOL Energy's current senior secured credit agreement expires on June 18, 2019. The credit facility allows for up to $2,000,000 of borrowings, which includes a $750,000 letters of credit sub-limit. CONSOL Energy can also request an additional $500,000 increase in the aggregate borrowing limit amount.

125

The current facility is secured by substantially all of the assets of CONSOL Energy and certain of its subsidiaries. Fees and interest rate spreads are based on the percentage of facility utilization, measured quarterly. Availability under the facility is limited to a borrowing base, which is determined by the lenders syndication agent and approved by the required number of lenders in good faith by calculating a value of CONSOL Energy's proved natural gas reserves.

The current facility contains a number of affirmative and negative covenants that limit the Company's ability to dispose of assets, make investments, purchase or redeem CONSOL Energy common stock, pay dividends, merge with another corporation and amend, modify or restate the senior unsecured notes. In April 2016, the facility was amended to require that the Company must: (i) prepay outstanding loans under the revolving credit facility to the extent that cash on hand exceeds $150,000 for two consecutive business days; (ii) mortgage 85% of its proved reserves and 80% of its proved developed producing reserves, in each case, which are included in the borrowing base; (iii) maintain applicable deposit, securities and commodities accounts with the lenders or affiliates thereof; and (iv) enter into control agreements with respect to such applicable accounts. In addition, the Company pledged the equity interest it holds in CONE Gathering, LLC and CONE Midstream Partners, LP as collateral to secure loans under the credit agreement.

The facility also requires that CONSOL Energy maintains a minimum interest coverage ratio of no less than 2.50 to 1.00, which is calculated as the ratio of Adjusted EBITDA to cash interest expense of CONSOL Energy and certain of its subsidiaries, measured quarterly. CONSOL Energy must also maintain a minimum current ratio of no less than 1.00 to 1.00, which is calculated as the ratio of current assets, plus revolver availability, to current liabilities, excluding borrowings under the revolver, measured quarterly. At December 31, 2016, the interest coverage ratio was 3.49 to 1.00 and the current ratio was 2.59 to 1.00. Further, the credit facility allows unlimited investments in joint ventures for the development and operation of natural gas gathering systems and permits CONSOL Energy to separate its E&P and coal businesses if the leverage ratio (which is, essentially, the ratio of debt to EBITDA) of the E&P business immediately after the separation would not be greater than 2.75 to 1.00. The calculation of all of the ratios exclude CNX Coal Resources LP (CNXC).

At December 31, 2016, the $2,000,000 facility had no borrowings outstanding and $325,676 of letters of credit outstanding, leaving $1,674,324 of unused capacity. At December 31, 2015, the $2,000,000 facility had $952,000 of borrowings outstanding and $258,177 of letters of credit outstanding, leaving $789,823 of unused capacity.

CONSOL Energy used the net proceeds of the sale of the Notes, together with borrowings under its revolving credit facility, to purchase $937,822 of its outstanding 8.25% senior notes due in 2020 and $229,176 of its outstanding 6.375% senior notes due in 2021. As part of this transaction, $67,734 was included in Loss on Debt Extinguishment on the Consolidated Statements of Income.

In April 2015, CONSOL Energy purchased $2,508 of its outstanding 8.25% senior notes due in 2020 and $213 of its outstanding 6.375% senior notes due in 2021. As part of this transaction, $17 was included in Loss on Debt Extinguishment on the Consolidated Statements of Income.

In July 2015, CNXC entered into a Credit Agreement for a $400,000 revolving credit facility. As of December 31, 2016 and 2015, CNXC had $201,000 and $185,000 of borrowings outstanding on the facility, respectively. CONSOL Energy is not a guarantor of CNXC's revolving credit facility. See Note 25 - Related Party Transactions for more information.

NOTE 14—PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS:

Pension:

CONSOL Energy has non-contributory defined benefit retirement plans. Effective December 31, 2015, CONSOL Energy's qualified defined benefit retirement plan was frozen. The benefits for these plans are based primarily on years of service and employees' pay. CONSOL Energy's qualified pension plan allows for lump-sum distributions of benefits earned up until December 31, 2005, at the employees' election.

On September 30, 2014, the qualified pension plan was remeasured to reflect an announced plan amendment that reduced future accruals of pension benefits as of January 1, 2015. The plan amendment called for a hard freeze of the qualified defined benefit pension plan on January 1, 2015 for employees who were under age 40 or had less than 10 years of service as of September 30, 2014. Employees who were age 40 or over and had at least 10 years of service continued in the defined benefit pension plan unchanged. The modifications to the pension plan resulted in a $21,624 reduction in the pension liability.

On August 31, 2015, the qualified pension plan was remeasured to reflect an announced plan amendment that reduced accruals of pension benefits as of January 1, 2016. The plan amendment called for a hard freeze of the qualified defined benefit pension plan on January 1, 2016 for all remaining participants in the plan. The modifications to the pension plan resulted in a $26,352 reduction in the pension liability. The amendment resulted in a remeasurement of the qualified pension plan at August 31, 2015, which increased the pension liability by $17,793.

In the third quarter of 2015, CONSOL Energy remeasured its pension plan as a result of the previously discussed plan amendment. In conjunction with this remeasurement, the method used to estimate the service and interest components of net periodic benefit cost for pension was changed. This change was also made to other postretirement benefits in the fourth quarter during the annual remeasurement of that plan. This change, compared to the previous method, resulted in a decrease in the service and interest components for pension cost in the third quarter. Historically, CONSOL Energy estimated these service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. CONSOL Energy has elected to utilize a full yield curve approach in the estimation of these components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. This change was made to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. This change is immaterial to CONSOL's financial statements. CONSOL Energy has accounted for this change as a change in accounting estimate that is inseparable from a change in accounting principle and, accordingly, accounted for it prospectively.

According to the Defined Benefit Plans Topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification, if the lump sum distributions made during a plan year, which for CONSOL Energy is January 1 to December 31, exceed the total of the projected service cost and interest cost for the plan year, settlement accounting is required. Lump sum payments exceeded this threshold during the years ended December 31,2016, 2015, and 2014. Accordingly, CONSOL Energy recognized settlement expense of $22,196, $19,053, and $29,095 for the years ended December 31,2016, 2015 and 2014 respectively, in Other Costs - Miscellaneous Operating Expense in the Consolidated Statements of Income. The settlement charges resulted in remeasurements of the pension plan during 2016, 2015 and 2014.

Other Postretirement Benefit Plans:

Certain subsidiaries of CONSOL Energy provide medical and prescription drug benefits to retired employees covered by the Coal Industry Retiree Health Benefit Act of 1992 (the Coal Act). Represented hourly employees are eligible to participate based upon the terms of the National Bituminous Coal Wage Agreement of 2011.

On September 30, 2014, the Salaried OPEB plan and Production and Maintenance (P&M) OPEB plans were remeasured to reflect an announced plan amendment that reduced retiree medical and life insurance benefits as of September 30, 2014. Effective September 30, 2014, no retiree medical, prescription drug or life benefits were to be provided to active employees. Salaried and P&M retirees as of September 30, 2014 were to continue in the OPEB plans for a maximum period up to December 31, 2019 and coverage thereafter was eliminated (see below for information on an additional amendment made to these plans in 2015). The Company elected to make cash transition payments totaling approximately $46,282 to the active employees whose retiree medical, prescription drug and life insurance benefits were eliminated by the changes to the OPEB plans. These cash payments are not considered to be post-retirement benefits, and as such, they are not reflected in the actuarial calculations related to the OPEB plans. The amendment to the OPEB plans resulted in a $315,439 reduction in the OPEB liability and a curtailment gain of $35,633.

129

On May 31, 2015, the Salaried OPEB and P&M OPEB plans were remeasured to reflect another plan amendment which eliminated Salaried and P&M OPEB benefits at December 31, 2015. The amendment to the OPEB plans resulted in a $43,598 reduction in the OPEB liability. The amendment also resulted in a remeasurement of the OPEB plan at May 31, 2015, which decreased the liability by $1,070. CONSOL Energy recognized income of $235,541 related to amortization of prior service credit, coupled with recognition of actuarial losses in PA Mining Operations Costs - Operating and Other Costs and Other Costs - Miscellaneous Operating Expense in the Consolidated Statements of Income for the year ended December 31, 2015 as a result of the changes made to the Salaried and P&M OPEB plans.

The Company will incur savings from cost containment changes related to pharmacy benefits, which were implemented on January 1, 2017, and increased member responsibility when using out-of-network providers and facilities, which will be implemented on March 27, 2017. These plan amendments resulted in a $28,164 reduction in the OPEB liability during the year ended December 31, 2016.

The reconciliation of changes in the benefit obligation, plan assets and funded status of these plans at December 31, 2016 and 2015 is as follows:

CONSOL Energy utilizes a corridor approach to amortize actuarial gains and losses that have been accumulated under the Pension Plan. Cumulative gains and losses that are in excess of 10% of the greater of either the projected benefit obligation (PBO) or the market-related value of plan assets are amortized over the expected remaining future lifetime of all plan participants for the Pension plan.

CONSOL Energy also utilizes a corridor approach to amortize actuarial gains and losses that have been accumulated under the OPEB Plan. Cumulative gains and losses that are in excess of 10% of the greater of either the accumulated postretirement benefit obligation (APBO) or the market-related value of plan assets are amortized over the average future remaining lifetime of the current inactive population for the OPEB plan.

The following table provides information related to pension plans with an accumulated benefit obligation in excess of plan assets:

	As of December 31,
	2016		2015
Projected benefit obligation	$	747,881	$	763,407
Accumulated benefit obligation	$	745,793	$	761,124
Fair value of plan assets	$	632,434	$	669,039

131

Assumptions:

The weighted-average assumptions used to determine benefit obligations are as follows:

	Pension Benefits				Other Postretirement Benefits
	For the Year Ended				For the Year Ended
	December 31,				December 31,
	2016		2015		2016		2015
Discount rate	4.31	%	4.50	%	4.22	%	4.50	%
Rate of compensation increase	3.90	%	3.80	%	—		—

The discount rates are determined using a Company-specific yield curve model (above-mean) developed with the assistance of an external actuary. The Company-specific yield curve models (above-mean) use a subset of the expanded bond universe to determine the Company-specific discount rate. Bonds used in the yield curve are rated AA by Moody's or Standard & Poor's as of the measurement date. The yield curve models parallel the plans' projected cash flows, and the underlying cash flows of the bonds included in the models exceed the cash flows needed to satisfy the Company plans.

The weighted-average assumptions used to determine net periodic benefit costs are as follows:

	Pension Benefits at						Other Postretirement Benefits at
	December 31,						December 31,
	2016		2015		2014		2016		2015		2014
Discount rate	4.52	%	4.07	%	4.87	%	4.50	%	4.03	%	4.88	%
Expected long-term return on plan assets	7.25	%	7.75	%	7.75	%	—		—		—
Rate of compensation increase	3.80	%	3.80	%	4.21	%	—		—		—

The long-term rate of return is the sum of the portion of total assets in each asset class held multiplied by the expected return for that class, adjusted for expected expenses to be paid from the assets. The expected return for each class is determined using the plan asset allocation at the measurement date and a distribution of compound average returns over a twenty year time horizon. The model uses asset class returns, variances and correlation assumptions to produce the expected return for each portfolio. The return assumptions used forward-looking gross returns influenced by the current Treasury yield curve. These returns recognize current bond yields, corporate bond spreads and equity risk premiums based on current market conditions.

The assumed health care cost trend rates are as follows:

	At December 31,
	2016		2015		2014
Health care cost trend rate for next year	6.31	%	6.49	%	6.03	%
Rate to which the cost trend is assumed to decline (ultimate trend rate)	4.50	%	4.50	%	4.50	%
Year that the rate reaches ultimate trend rate	2038		2038		2026

Assumed health care cost trend rates have a significant effect on the amounts reported for the medical plans. A one-percentage point change in assumed health care cost trend rates would have the following effects:

	1 Percentage		1 Percentage
	Point Increase		Point Decrease
Effect on total of service and interest cost components	$	3,659	$	(3,053	)
Effect on accumulated postretirement benefit obligation	$	84,381	$	(71,751	)

132

Plan Assets:

The Company’s overall investment strategy is to meet current and future benefit payment needs through diversification across asset classes, fund strategies and fund managers to achieve an optimal balance between risk and return and between income and growth of assets through capital appreciation. Consistent with the objectives of the Trust and in consideration of the Trust’s current funded status and the current level of market interest rates, the Retirement Board has approved an asset allocation strategy that will change over time in response to future improvements in the Trust’s funded status and/or changes in market interest rates. Such changes in asset allocation strategy are intended to allocate additional assets to the fixed income asset class should the Trust’s funded status improve. In this framework, the current target allocation for plan assets are 26% U.S. equity securities, 16.5% non-U.S. equity securities, 7.5% global equity securities and 50% fixed income. Both the equity and fixed income portfolios are comprised of both active and passive investment strategies. The Trust is primarily invested in Mercer Common Collective Trusts. Equity securities consist of investments in large and mid/small cap companies with non-U.S. equities being derived from both developed and emerging markets. Fixed income securities consist of U.S. as well as international instruments, including emerging markets. The core domestic fixed income portfolios invest in government, corporate, asset-backed securities and mortgage-backed obligations. The average quality of the fixed income portfolio must be rated at least “investment grade” by nationally recognized rating agencies. Within the fixed income asset class, investments are invested primarily across various strategies such that its overall profile strongly correlates with the interest rate sensitivity of the Trust’s liabilities in order to reduce the volatility resulting from the risk of changes in interest rates and the impact of such changes on the Trust’s overall financial status. Derivatives, interest rate swaps, options and futures are permitted investments for the purpose of reducing risk and to extend the duration of the overall fixed income portfolio; however, they may not be used for speculative purposes. All or a portion of the assets may be invested in mutual funds or other commingled vehicles so long as the pooled investment funds have an adequate asset base relative to their asset class; are invested in a diversified manner; and have management and/or oversight by an Investment Advisor registered with the SEC. The Retirement Board, as appointed by the CONSOL Energy Board of Directors, reviews the investment program on an ongoing basis including asset performance, current trends and developments in capital markets, changes in Trust liabilities and ongoing appropriateness of the overall investment policy.

In May 2015, the FASB issued an Accounting Standards Update that removes the requirement to categorize within the fair value hierarchy investments for which fair values are estimated using the net asset value practical expedient provided by Accounting Standards Codification 820, Fair Value Measurement. This new guidance is effective for public entities for fiscal years beginning after December 15, 2015. In accordance with this Update, certain investments in 2016 and 2015 that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified as Level 1, 2 or 3 in the below fair value hierarchy but are included in the total.

The fair values of plan assets at December 31, 2016 and 2015 by asset category are as follows:

	Fair Value Measurements at December 31, 2016								Fair Value Measurements at December 31, 2015

(a) This category includes investments in US common stocks and corporate debt.

(b) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy but are included in the total.

There are no investments in CONSOL Energy stock held by these plans at December 31, 2016 or 2015.

There are no assets in the other postretirement benefit plans at December 31, 2016 or 2015.

133

Cash Flows:

If necessary, CONSOL Energy intends to contribute to the pension trust using prudent funding methods. However, the Company does not expect to contribute to the pension plan trust in 2017. Pension benefit payments are primarily funded from the trust. CONSOL Energy expects to pay benefits of $2,904 from the non-qualified pension plan in 2017. CONSOL Energy does not expect to contribute to the other postemployment plan in 2017 and intends to pay benefit claims as they are due.

The following benefit payments, reflecting expected future service, are expected to be paid:

			Other
	Pension		Postretirement
	Benefits		Benefits
2017	$	47,374	$	40,611
2018	$	47,100	$	43,829

NOTE 15—COAL WORKERS’ PNEUMOCONIOSIS (CWP) AND WORKERS’ COMPENSATION:

Under the Federal Coal Mine Health and Safety Act of 1969, as amended, CONSOL Energy is responsible for medical and disability benefits to employees and their dependents resulting from occurrences of coal workers' pneumoconiosis disease. CONSOL Energy is also responsible under various state statutes for pneumoconiosis benefits. CONSOL Energy primarily provides for these claims through a self-insurance program. The calculation of the actuarial present value of the estimated pneumoconiosis obligation is based on an annual actuarial study by independent actuaries and uses assumptions regarding disability incidence, medical costs, indemnity levels, mortality, death benefits, dependents and interest rates which are derived from actual company experience and outside sources. Recent legislative changes have not been favorable for CWP. Although these changes have not had a significant impact on the liability, CONSOL has noticed an increase in claims. Actuarial gains or losses can result from differences in incident rates and severity of claims filed as compared to original assumptions.

CONSOL Energy must also compensate individuals who sustain employment-related physical injuries or some types of occupational diseases and, on some occasions, for costs of their rehabilitation. Workers' compensation laws will also compensate survivors of workers who suffer employment-related deaths. Workers' compensation laws are administered by state agencies, and each state has its own set of rules and regulations regarding compensation that is owed to an employee that is injured in the course of employment. CONSOL Energy primarily provides for these claims through a self-insurance program. CONSOL Energy recognizes an actuarial present value of the estimated workers' compensation obligation calculated by independent actuaries. The calculation is based on claims filed and an estimate of claims incurred but not yet reported as well as various assumptions, including discount rate, future healthcare trend rate, benefit duration and recurrence of injuries. Actuarial gains or losses associated with workers' compensation have resulted from discount rate changes and differences in claims experience and incident rates as compared to prior assumptions.

Net amount recognized (before tax effect)	$	(62,714	)	$	(68,101	)	$	(12,914	)	$	(13,440	)

The components of the net periodic cost are as follows:

	CWP									Workers’ Compensation
	For the Years Ended									For the Years Ended
	December 31,									December 31,
	2016			2015			2014			2016			2015			2014

Net periodic cost	$	2,355		$	6,031		$	5,015		$	13,030		$	16,134		$	16,328

(Income) expense attributable to discontinued operations included in the CWP net periodic cost was $(1,290), $297 and $87 for the years ended December 31, 2016, 2015 and 2014, respectively.

On March 31, 2016, CONSOL Energy completed the sale of its membership interests in BMC (see Note 2 - Discontinued Operations). As a result of the sale, certain obligations of the CWP plan were transferred to the buyer. This transfer triggered a curtailment gain of $1,307. The curtailment resulted in a plan remeasurement increasing plan liabilities by $7,713 at March 31, 2016.

135

The following are amounts included in accumulated other comprehensive income that are expected to be recognized in 2017 net periodic benefit costs:

				Workers'
	CWP			Compensation
	Benefits			Benefits
Actuarial gain recognition	$	(7,631	)	$	(610	)

CONSOL Energy utilizes a corridor approach to amortize actuarial gains and losses that have been accumulated under the Workers’ Compensation and CWP plans. Cumulative gains and losses that are in excess of 10% of the greater of either the estimated liability or the market-related value of plan assets are amortized over the expected average remaining future service of the current active membership of the Workers’ Compensation and CWP plans.

Assumptions:

The weighted-average discount rates used to determine benefit obligations and net periodic cost (benefit) are as follows:

	CWP						Workers' Compensation
	For the Years Ended						For the Years Ended
	December 31,						December 31,
	2016		2015		2014		2016		2015		2014
Benefit obligations	4.40	%	4.60	%	4.21	%	4.05	%	4.26	%	3.84	%
Net periodic cost	4.60	%	4.21	%	4.75	%	4.26	%	3.84	%	4.57	%

Discount rates are determined using a Company-specific yield curve model (above-mean) developed with the assistance of an external actuary. The Company-specific yield curve models (above-mean) use a subset of the expanded bond universe to determine the Company-specific discount rate. Bonds used in the yield curve are rated AA by Moody's or Standard & Poor's as of the measurement date. The yield curve models parallel the plans' projected cash flows, and the underlying cash flows of the bonds included in the models exceed the cash flows needed to satisfy the Company's plans.

Cash Flows:

CONSOL Energy does not intend to make contributions to the CWP or Workers' Compensation plans in 2017, but it intends to pay benefit claims as they become due.

The following benefit payments, which reflect expected future claims as appropriate, are expected to be paid:

			Workers' Compensation
	CWP		Total		Actuarial		Other
	Benefits		Benefits		Benefits		Benefits
2017	$	10,763	$	15,897	$	12,416	$	3,481

NOTE 16—OTHER EMPLOYEE BENEFIT PLANS:

UMWA Benefit Trusts:

The Coal Act created two multi-employer benefit plans: (1) the United Mine Workers of America Combined Benefit Fund (the Combined Fund) into which the former UMWA Benefit Trusts were merged, and (2) the United Mine Workers of America 1992 Benefit Plan (1992 Benefit Plan). CONSOL Energy accounts for required contributions to these multi-employer trusts as expense when incurred.

The Combined Fund provides medical and death benefits for all beneficiaries of the former UMWA Benefit Trusts who were actually receiving benefits as of July 20, 1992. The 1992 Benefit Plan provides medical and death benefits to orphan UMWA-represented members eligible for retirement on February 1, 1993, and for those who retired between July 20, 1992 and September 30, 1994. The Coal Act provides for the assignment of beneficiaries to former employers and the allocation of unassigned beneficiaries (referred to as orphans) to companies using a formula set forth in the Coal Act. The Coal Act requires that responsibility for funding the benefits to be paid to beneficiaries be assigned to their former signatory employers or related companies. This cost is recognized when contributions are assessed. CONSOL Energy's total contributions under the Coal Act were $8,455, $9,239 and $10,121 for the years ended December 31, 2016, 2015 and 2014, respectively. Based on available information at December 31, 2016, CONSOL Energy's obligation for the Combined Fund and 1992 Benefit Plans is estimated to be approximately $93,795.

Pursuant to the provisions of the Tax Relief and Healthcare Act of 2006 (the 2006 Act) and the 1992 Benefit Plan, CONSOL Energy is required to provide security in an amount based on the annual cost of providing health care benefits for all individuals receiving benefits from the 1992 Benefit Plan who are attributable to CONSOL Energy, plus all individuals receiving benefits from an individual employer plan maintained by CONSOL Energy who are entitled to receive such benefits. In accordance with the terms of the 2006 Act and the 1992 Benefit Plan, CONSOL Energy must secure its obligations by posting letters of credit, which were $19,170, $21,473 and $21,394 at December 31, 2016, 2015 and 2014, respectively. The 2016, 2015 and 2014 security amounts were based on the annual cost of providing health care benefits and included a reduction in the number of eligible employees.

Investment Plan:

CONSOL Energy has an investment plan available to most non-represented employees. Throughout the year ended December 31, 2016, the Company's matching contribution was 6% of eligible compensation contributed by eligible employees. In conjunction with the qualified pension plan changes in 2015, the Company contributed an additional 3% of eligible compensation into the 401(k) plan accounts for employees hired or rehired on or after October 1, 2014 or who were under age 40 or had less than 10 years of service with the Company as of September 30, 2014. This additional contribution was eliminated on January 1, 2016. The Company may also make discretionary contributions to the Plan ranging from 1% to 6% (1% to 4% prior to January 1, 2016) of eligible compensation for eligible employees (as defined by the Plan). Discretionary contributions made by the Company were $12,260 for the year ended December 31, 2016. There were no such discretionary contributions made by the Company for the years ended December 31, 2015 and 2014. Total payments and costs were $20,784, $20,058 and $18,341 for the years ended December 31, 2016, 2015 and 2014, respectively.

Long-Term Disability:

CONSOL Energy has a Long-Term Disability Plan available to all eligible full-time salaried employees. The benefits for this plan are based on a percentage of monthly earnings, offset by all other income benefits available to the disabled.

	For the Years Ended
	December 31,
	2016			2015			2014
Benefit cost	$	2,128		$	2,619		$	2,213
Discount rate assumption used to determine net periodic benefit costs	3.71		%	3.18		%	3.53		%

Liabilities incurred under the Long-Term Disability Plan are included in Other Accrued Liabilities and Deferred Credits and Other Liabilities–Other in the Consolidated Balance Sheets and amounted to a combined total of $19,144 and $19,789 at December 31, 2016 and 2015, respectively.

NOTE 17—STOCK-BASED COMPENSATION:

CONSOL Energy adopted the CONSOL Energy Inc. Equity Incentive Plan (the Equity Incentive Plan) on April 7, 1999. The Equity Incentive Plan provides for grants of stock-based awards to key employees and to non-employee directors. Amendments to the Equity Incentive Plan have been adopted and approved by the Board of Directors and the Company's Shareholders since the commencement of the plan. Most recently, in May 2016, the Board of Directors and the Company's Shareholders adopted and approved a 10,550,000 increase to the total number of shares available for issuance, which brought the total number of shares of common stock that can be covered by grants to 42,350,000. At December 31, 2016, 8,733,169 shares of common stock remain available for all awards. The Equity Incentive Plan provides that the aggregate number of shares available for issuance will be reduced by one share for each share issued in settlement of stock options and by 1.62 for each share issued in settlement of Performance Share Units (PSUs) or Restricted Stock Units (RSUs). No award of stock options may be exercised under the Equity Incentive Plan after the tenth anniversary of the effective date of the award.

For only those shares expected to vest, CONSOL Energy recognizes stock-based compensation costs on a straight-line basis over the requisite service period of the award, which is generally the vesting term. Awards granted in 2014 vest immediately if granted to retiree-eligible employees who are aged 62 and older. Awards granted in 2014 vest at the end of one year when granted to employees aged 55 to 62 and who have also completed ten years of service. Awards granted in 2014 vest over a three-year term at 33% per year for all other employees. Awards granted in 2015 vest over a three-year term at 33% per year. Options and RSUs granted in 2016 vest over a three-year term at 33% per year. Performance share units granted in 2016 vest over a five-year term at 20% per year subject to performance conditions. If an employee leaves the Company, all unvested shares are forfeited. The vesting of all awards will accelerate in the event of death and disability and may accelerate upon a change in control of CONSOL Energy. See each specific award section for special vesting terms related to non-employee directors and other specific awards. The total stock-based compensation expense recognized during the years ended December 31, 2016, 2015 and 2014 was $31,483, $24,513 and $41,877, respectively. The related deferred tax benefit totaled $11,255, $9,229 and $15,243, for the years ended December 31, 2016, 2015 and 2014, respectively.

As of December 31, 2016, CONSOL Energy has $40,234 of unrecognized compensation cost related to all nonvested stock-based compensation awards, which is expected to be recognized over a weighted-average period of 2.73 years. When stock options are exercised and restricted and performance stock unit awards become vested, the issuances are made from CONSOL Energy's common stock shares.

Stock Options:

CONSOL Energy examined its historical pattern of option exercises in an effort to determine if there were any discernable activity patterns based on certain employee populations. From this analysis, CONSOL Energy identified two distinct employee populations and used the Black-Scholes option pricing model to value the options for each of the employee populations. The expected term computation presented in the table below is based upon a weighted average of the historical exercise patterns and post-vesting termination behavior of the two populations. The risk-free interest rate was determined for each vesting tranche of an award based upon the calculated yield on U.S. Treasury obligations for the expected term of the award. The expected forfeiture rate is based upon historical forfeiture activity. A combination of historical and implied volatility is used to determine expected volatility and future stock price trends. The total fair value of options granted during the year ended December 31, 2016 was $19,305, based on the following assumptions and weighted average fair values:

	December 31,
	2016
Weighted average fair value of grants	$	5.73
Risk-free interest rate	1.13		%
Expected dividend yield	0.27		%
Expected forfeiture rate	2.00		%
Expected volatility	61.09		%
Expected term in years	4.90

CONSOL Energy did not grant stock option awards during the years ended December 31, 2015 or 2014.

Exercisable at December 31, 2016	2,990,263		$43.12	2.57	$	—

At December 31, 2016, there are 5,888,075 employee stock options outstanding under the Equity Incentive Plan. Non-employee director stock options vest one year after the grant date. There are 320,738 fully vested stock options outstanding under these grants.

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between CONSOL Energy's closing stock price on the last trading day of the year ended December 31, 2016 and the option's exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2016. This amount varies based on the fair market value of CONSOL Energy's stock. No options were exercised during the year ended December 31, 2016. The total intrinsic value of options exercised for the years ended December 31, 2015 and 2014 was $2,744 and $14,545, respectively.

Cash received from option exercises for the years ended December 31, 2015 and 2014 was $8,281 and $15,011, respectively. The tax impact from option exercises totaled $208 and $2,629 for the years ended December 31, 2015 and 2014, respectively. This excess tax benefit is included in cash flows from financing activities in the Consolidated Statements of Cash Flows.

Restricted Stock Units:

Under the Equity Incentive Plan, CONSOL Energy grants certain employees and non-employee directors restricted stock unit awards, which entitle the holder to shares of common stock as the award vests. Non-employee director restricted stock units vest at the end of one year. In 2014, restricted stock units were granted that will vest over a five year period unless certain market conditions are met, in which the award will accelerate. Compensation expense is recognized over the vesting period of the units, described above. The total fair value of restricted stock units granted during the years ended December 31, 2016, 2015 and 2014 was $493, $26,550 and $31,360, respectively. The total fair value of restricted stock units vested during the years ended December 31, 2016, 2015 and 2014 was $19,095, $20,793 and $15,686, respectively. The following table represents the nonvested restricted stock units and their corresponding fair value (based upon the closing share price) at the date of grant:

	Number of		Weighted Average

Forfeited	(88,703	)	$30.42
Nonvested at December 31, 2016	663,003		$31.97

Performance Share Units:

Under the Equity Incentive Plan, CONSOL Energy grants certain employees performance share unit awards, which entitle the holder to shares of common stock subject to the achievement of certain market and performance goals. Compensation expense is recognized over the performance measurement period of the units in accordance with the provisions of the Stock Compensation Topic of the FASB Accounting Standards Codification for awards with market and performance vesting conditions. For the PSUs issued in 2014 and 2015, achievement of the market goals is not probable, but achievement of the performance goals is probable.

139

Achievement of the market goals is probable for the first tranche of the PSUs issued in 2016. The total fair value of performance share units granted during the years ended December 31, 2016, 2015 and 2014 was $24,283, $18,771 and $11,853, respectively. No performance share units vested during the year ended December 31, 2016. The total fair value of performance share units vested during the years ended December 31, 2015 and 2014 was $20,083 and $18,759, respectively. The following table represents the nonvested performance share units and their corresponding fair value (based upon the closing share price) on the date of grant:

	Number of		Weighted Average

Performance Options:

Under the Equity Incentive Plan in 2010, CONSOL Energy granted certain employees performance options, which entitled the holder to shares of common stock subject to the achievement of certain performance goals. Compensation expense was recognized over the vesting period of the options, described above. The Black-Scholes option valuation model was used to value each tranche separately. No performance options were granted in 2016, 2015, or 2014. No performance options vested in 2016 or 2015. The total fair value of performance options vested during the year ended December 31, 2014 was $4,949. A summary of the status of performance options granted is presented below:

CONSOL Stock Units:

Under the Equity Incentive Plan in 2013, CONSOL Energy granted certain employees CONSOL Stock Unit Awards, which entitled the holder to shares of common stock subject to the achievement of certain market and performance goals. Compensation expense was recognized over the performance measurement period of the units in accordance with the provisions of the Stock Compensation Topic of the FASB Accounting Standards Codification for awards with market and performance vesting conditions. CONSOL Energy used the Monte Carlo methodology to estimate the fair value of the CONSOL Stock Units. The achievement of the market and performance goals was not attained and therefore, all shares were forfeited in 2016. No CONSOL Stock Units were granted in 2016. The total fair value of CONSOL Stock Units granted during the years ended December 31, 2015 and 2014 was $110 and $189 respectively. The following table represents the nonvested CONSOL Stock Unit awards and their corresponding fair value at the grant date:

No sales to any E&P or coal customer exceeded 10% of the Company's revenues during the year ended December 31, 2016.

During the year ended December 31, 2015, coal sales to Duke Energy were $242,020, which comprised over 10% of the Company's revenues.

During the year ended December 31, 2014, E&P sales to NJR Energy Services Company were $295,779, which comprised over 10% of the Company's revenues.

NOTE 20—FAIR VALUE OF FINANCIAL INSTRUMENTS:

CONSOL Energy determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources (including NYMEX forward curves, LIBOR-based discount rates and basis forward curves), while unobservable inputs reflect the Company's own assumptions of what market participants would use.

The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below:

Level One - Quoted prices for identical instruments in active markets.

Level Two - The fair value of the assets and liabilities included in Level 2 are based on standard industry income approach models that use significant observable inputs, including NYMEX forward curves, LIBOR-based discount rates and basis forward curves.

141

Level Three - Unobservable inputs significant to the fair value measurement supported by little or no market activity. The significant unobservable inputs used in the fair value measurement of the Company's third party guarantees are the credit risk of the third party and the third party surety bond markets. A significant increase or decrease in these values, in isolation, would have a directionally similar effect resulting in higher or lower fair value measurement of the Company's Level 3 guarantees.

In those cases when the inputs used to measure fair value meet the definition of more than one level of the fair value hierarchy, the lowest level input that is significant to the fair value measurement in its totality determines the applicable level in the fair value hierarchy.

The financial instruments measured at fair value on a recurring basis are summarized below:

	Fair Value Measurements at December 31, 2016								Fair Value Measurements at December 31, 2015
Description	Level 1		Level 2			Level 3			Level 1		Level 2		Level 3
Gas Derivatives	$	—	$	(188,156	)	$	—		$	—	$	266,558	$	—
Murray Energy Guarantees	$	—	$	—		$	(1,362	)	$	—	$	—	$	(1,228	)

The following methods and assumptions were used to estimate the fair value for which the fair value option was not elected:

Cash and cash equivalents: The carrying amount reported in the balance sheets for cash and cash equivalents approximates its fair value due to the short-term maturity of these instruments.

Short-term notes payable: The carrying amount reported in the Consolidated Balance Sheets for short-term notes payable approximates its fair value due to the short-term maturity of these instruments.

Long-term debt: The fair value of long-term debt is measured using unadjusted quoted market prices or estimated using discounted cash flow analyses. The discounted cash flow analyses are based on current market rates for instruments with similar cash flows.

The carrying amounts and fair values of financial instruments for which the fair value option was not elected are as follows:

	December 31, 2016				December 31, 2015
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
Cash and Cash Equivalents	$	60,475	$	60,475	$	72,574	$	72,574
Short-Term Notes Payable	$	—	$	—	$	952,000	$	952,000
Long-Term Debt	$	2,752,371	$	2,717,582	$	2,738,735	$	1,808,936

Cash and cash equivalents represent highly-liquid instruments and constitute Level 1 fair value measurements. Certain of the Company’s debt is actively traded on a public market and, as a result, constitute Level 1 fair value measurements. The portion of the Company’s debt obligations that are not actively traded are valued through reference to the applicable underlying benchmark rate and, as a result, constitute Level 2 fair value measurements.

NOTE 21—DERIVATIVE INSTRUMENTS:

CONSOL Energy enters into financial derivative instruments to manage its exposure to commodity price volatility. CONSOL Energy de-designated all of its cash flow hedges on December 31, 2014 and accounts for all existing and future gas and NGL commodity hedges on a mark-to-market basis with changes in fair value recorded in current period earnings. In connection with this de-designation, CONSOL Energy froze the balances recorded in Accumulated Other Comprehensive Income at December 31, 2014 and reclassified balances to earnings as the underlying physical transactions occurred. As of December 31, 2016, all gains deferred in OCI have been recognized in earnings.

CONSOL Energy is exposed to credit risk in the event of non-performance by counterparties. The creditworthiness of counterparties is subject to continuing review. The Company has not experienced any issues of non-performance by derivative counterparties.

None of the Company's counterparty master agreements currently require CONSOL Energy to post collateral for any of its positions. However, as stated in the counterparty master agreements, if CONSOL Energy's obligations with one of its counterparties cease to be secured on the same basis as similar obligations with the other lenders under the credit facility, CONSOL Energy would have to post collateral for instruments in a liability position in excess of defined thresholds. All of the Company's

142

derivative instruments are subject to master netting arrangements with our counterparties. CONSOL Energy recognizes all financial derivative instruments as either assets or liabilities at fair value on the Consolidated Balance Sheets on a gross basis.

Each of CONSOL Energy's counterparty master agreements allows, in the event of default, the ability to elect early termination of outstanding contracts. If early termination is elected, CONSOL Energy and the applicable counterparty would net settle all open hedge positions.

NOTE 22—COMMITMENTS AND CONTINGENT LIABILITIES:

CONSOL Energy and its subsidiaries are subject to various lawsuits and claims with respect to such matters as personal injury, wrongful death, damage to property, exposure to hazardous substances, governmental regulations including environmental remediation, employment and contract disputes and other claims and actions arising out of the normal course of business. CONSOL Energy accrues the estimated loss for these lawsuits and claims when the loss is probable and can be estimated. The Company's current estimated accruals related to these pending claims, individually and in the aggregate, are immaterial to the financial position, results of operations or cash flows of CONSOL Energy. It is possible that the aggregate loss in the future with respect to these lawsuits and claims could ultimately be material to the financial position, results of operations or cash flows of CONSOL Energy; however, such amounts cannot be reasonably estimated. The amount claimed against CONSOL Energy is disclosed below when an amount is expressly stated in the lawsuit or claim, which is not often the case. The maximum aggregate amount claimed in those lawsuits and claims, regardless of probability, where a claim is expressly stated or can be estimated, exceeds the aggregate amounts accrued for all lawsuits and claims by approximately $937,421.

The following lawsuits and claims include those for which a loss is probable and an accrual has been recognized.

144

Hale Litigation: This class action lawsuit was filed on September 23, 2010 in the U.S. District Court in Abingdon, Virginia. The putative class consists of force-pooled unleased gas owners whose ownership of the coalbed methane (CBM) gas was declared to be in conflict with rights of others. The lawsuit seeks a judicial declaration of ownership of the CBM and damages based on allegations CNX Gas Company failed to either pay royalties due to conflicting claimants or deemed lessors or paid them less than required because of the alleged practice of improper below market sales and/or taking alleged improper post-production deductions. On September 30, 2013, the District Judge entered an Order certifying the class, and CNX Gas Company appealed the Order to the U.S. Fourth Circuit Court of Appeals. On August 19, 2014, the Fourth Circuit agreed with CNX Gas Company, reversed the Order certifying the class and remanded the case to the trial court for further proceedings consistent with the decision. On April 23, 2015, Plaintiffs filed a Renewed Motion for Class Certification, and on June 23, 2015, CNX Gas Company filed its Opposition to same. The Court held a hearing on the Motion on September 18, 2015 and has not yet ruled. CONSOL Energy continues to believe this action cannot properly proceed as a class action in any form, believes the case has meritorious defenses, and intends to defend it vigorously. The Company has established an accrual to cover its estimated liability for this case. This accrual is immaterial to the overall financial position of CONSOL Energy and is included in Other Accrued Liabilities on the Consolidated Balance Sheets.

Addison Litigation: This class action lawsuit was filed on April 28, 2010 in the U.S. District Court in Abingdon, Virginia. The putative class consists of gas lessors whose gas ownership is in conflict. The lawsuit seeks a judicial declaration of ownership of the CBM and damages based on the allegations that CNX Gas Company failed to either pay royalties due to these conflicting claimant lessors or paid them less than required because of the alleged practice of improper below market sales and/or taking alleged improper post-production deductions. On September 30, 2013, the District Judge entered an Order certifying the class, and CNX Gas Company appealed the Order to the U.S. Fourth Circuit Court of Appeals. On August 19, 2014, the Fourth Circuit agreed with CNX Gas Company, reversed the Order certifying the class and remanded the case to the trial court for further proceedings consistent with the decision. On April 23, 2015, Plaintiffs filed a Renewed Motion for Class Certification, and on June 23, 2015, CNX Gas Company filed its Opposition to same. The Court held a hearing on the Motion on September 18, 2015 and has not yet ruled. CONSOL Energy continues to believe this action cannot properly proceed as a class action in any form, believes the case has meritorious defenses, and intends to defend it vigorously. The Company has established an accrual to cover its estimated liability for this case. This accrual is immaterial to the overall financial position of CONSOL Energy and is included in Other Accrued Liabilities on the Consolidated Balance Sheets.

The following royalty, land rights and other lawsuits and claims include those for which a loss is reasonably possible, but not probable, and accordingly, an accrual may not have been recognized. These claims are influenced by many factors which prevent the estimation of a range of potential loss. These factors include, but are not limited to, generalized allegations of unspecified damages (such as improper deductions), discovery having not commenced or not having been completed, unavailability of expert reports on damages and non-monetary issues being tried. For example, in instances where a gas lease termination is sought, damages would depend on speculation as to if and when the gas production would otherwise have occurred, how many wells would have been drilled on the lease premises, what their production would be, what the cost of production would be, and what the price of gas would be during the production period. An estimate is calculated, if applicable, when sufficient information becomes available.

Fitzwater Litigation: Two nonunion retired coal miners have sued CONSOL Energy Inc., Fola Coal Company and Consolidation Coal Company in West Virginia Federal Court alleging ERISA violations in the termination of retiree health care benefits. The Plaintiffs contend they relied to their detriment on oral statements and promises of "lifetime health benefits" allegedly made by various members of management during Plaintiffs' employment and that they were allegedly denied access to Summary Plan Documents that clearly reserved to the Company the right to modify or terminate the CONSOL Energy Inc. Retiree Health and Welfare Plan. Plaintiffs request that retiree health benefits be reinstated and seek to represent a class of all nonunion retirees of CONSOL Energy and its subsidiaries. The Company believes it has meritorious defense and intends to vigorously defend this suit.

Virginia Mine Void Litigation: The Company is currently defending three lawsuits naming Consolidation Coal Company (CCC), Island Creek Coal Company (ICCC), CNX Gas Company, and/or CONSOL Energy. The lawsuits were filed in the U.S. District Court for the Western District of Virginia. On October 26, 2015, the trial court granted summary judgment in favor of the defendants in two of the actions upon its finding that plaintiffs' claims are barred by the applicable statutes of limitation. Plaintiffs have appealed both cases to the U.S. Court of Appeals for the Fourth Circuit. Oral argument was held on December 8, 2016. The third case remains pending in the trial court. On January 26, 2016, six mine void lawsuits that have twice before been filed and voluntarily dismissed, were refiled for a third time in state court but have not been served. The Complaints seek damages and injunctive relief in connection with the transfer of water from mining activities at Buchanan Mine into void spaces in inactive ICCC mines adjacent to the Buchanan operations, voids ostensibly underlying plaintiffs’ properties. While some of the plaintiffs have an ownership interest in the coal, others have some interest in one or more of the fee, surface, oil/gas or other mineral estates. The suits allege the water storage precludes access to and has damaged coal, impeded coalbed methane gas production and was

145

made without compensation to the property owners. Plaintiffs seek recovery in tort, contract and trespass assumpsit (quasi-contract). The suits each seek damages between $50,000 and in excess of $100,000 plus punitive damages. The Company intends to vigorously defend these suits.

At December 31, 2016, CONSOL Energy has provided the following financial guarantees, unconditional purchase obligations and letters of credit to certain third parties, as described by major category in the following table. These amounts represent the maximum potential of total future payments that the Company could be required to make under these instruments. These amounts have not been reduced for potential recoveries under recourse or collateralization provisions. Generally, recoveries under reclamation bonds would be limited to the extent of the work performed at the time of the default. No amounts related to these financial guarantees and letters of credit are recorded as liabilities in the financial statements. CONSOL Energy management believes that these guarantees will expire without being funded, and therefore the commitments will not have a material adverse effect on financial condition.

Included in the above table are commitments and guarantees entered into in conjunction with the sale of Consolidation Coal Company and certain of its subsidiaries, which contain all five of its longwall coal mines in West Virginia, and its river operations to a subsidiary of Murray Energy Corporation (Murray Energy). As part of the sales agreement, CONSOL Energy has guaranteed certain equipment lease obligations and coal sales agreements that were assumed by Murray Energy. In the event that Murray Energy would default on the obligations defined in the agreements, CONSOL Energy would be required to perform under the guarantees. If CONSOL Energy would be required to perform, the stock purchase agreement provides various recourse actions. At December 31, 2016 and December 31, 2015, the fair value of these guarantees was $1,362 and $1,228, respectively, and are included in Other Accrued Liabilities on the Consolidated Balance Sheets. The fair value of certain of the guarantees was determined using CONSOL Energy’s risk-adjusted interest rate. Significant increases or decreases in the risk-adjusted interest rates may result in a significantly higher or lower fair value measurement. Coal sales agreement guarantees were valued based on an evaluation of coal market pricing compared to contracted sales price and includes an adjustment for nonperformance risk. No other amounts related to financial guarantees and letters of credit are recorded as liabilities in the financial statements. Significant judgment is required in determining the fair value of these guarantees. The guarantees of the leases and sales agreements are classified within Level 3 of the fair value hierarchy.

As part of the sale of Buchanan Mine (See Note 2 - Discontinued Operations), CONSOL Energy has guaranteed certain equipment lease obligations that were assumed by Coronado. In the event that Coronado would default on the obligations defined in the agreements, CONSOL Energy would be required to perform under the guarantees. 

CONSOL Energy regularly evaluates the likelihood of default for all guarantees based on an expected loss analysis and records the fair value, if any, of its guarantees as an obligation in the consolidated financial statements. 

CONSOL Energy and CNX Gas Company enter into long-term unconditional purchase obligations to procure major equipment purchases, natural gas firm transportation, gas drilling services and other operating goods and services. These purchase

146

obligations are not recorded on the Consolidated Balance Sheets. As of December 31, 2016, the purchase obligations for each of the next five years and beyond were as follows:

Obligations Due	Amount
Less than 1 year	$	209,797
1 - 3 years	285,224
3 - 5 years	243,534
More than 5 years	622,509
Total Purchase Obligations	$	1,361,064

NOTE 23—SEGMENT INFORMATION:

CONSOL Energy consists of two principal business divisions: Exploration and Production (E&P) and Pennsylvania (PA) Mining Operations. The principal activity of the E&P division, which includes four reportable segments, is to produce pipeline quality natural gas for sale primarily to gas wholesalers. The E&P division's reportable segments are Marcellus Shale, Utica Shale, Coalbed Methane, and Other Gas. The Other Gas segment is primarily related to shallow oil and gas production and the Chattanooga Shale in Tennessee, neither of which are significant to the Company. It also includes the Company's purchased gas activities, unrealized gain or loss on commodity derivative instruments, exploration and production related other costs, other corporate expenses, selling, general and administrative activities, as well as various other activities assigned to the E&P division but not allocated to each individual segment. The principal activities of the PA Mining Operations division are mining, preparation and marketing of thermal coal, sold primarily to power generators. It also includes selling, general and administrative activities, as well as various other activities assigned to the PA Mining Operations division.

CONSOL Energy’s Other division includes expenses from various corporate and diversified business activities that are not allocated to the E&P or PA Mining Operations divisions. The diversified business activities include coal terminal operations, closed and idle mine activities, water operations, selling, general and administrative activities, as well as various other non-operated activities, none of which are individually significant to the Company. In previous periods, this division included activity from the sales of industrial supplies (this subsidiary was sold in December 2014).

Prior to the sale of the Buchanan Mine on March 31, 2016 and the Fola and Miller Creek Complexes on August 1, 2016 (see Note 2 - Discontinued Operations), CONSOL Energy had a Coal division. The Coal division had three reportable segments; PA Operations, Virginia (VA) Operations and Other Coal. The VA Operations segment included the Buchanan Mine and the Other Coal segment was primarily comprised of the assets and operations of the Fola and Miller Creek Complexes, as well as coal terminal operations, closed and idle mine activities, selling, general and administrative activities and various other non-operated activities. PA Operations now constitutes its own division and reportable segment and the remaining activity in the Other Coal segment became part of CONSOL Energy's diversified business activities in the Other division. Prior periods have been reclassified to align with current period presentation.

In the preparation of the following information, intersegment sales have been recorded at amounts approximating market. Operating profit for each segment is based on sales less identifiable operating and non-operating expenses. Assets are reflected at the division level for E&P and are not allocated between each individual E&P segment. These assets are not allocated to each individual segment due to the diverse asset base controlled by CONSOL Energy, whereby each individual asset may service more than one segment within the division. An allocation of such asset base would not be meaningful or representative on a segment by segment basis.

NOTE 24—GUARANTOR SUBSIDIARIES FINANCIAL INFORMATION:

The payment obligations under the $74,470, 8.250% per annum senior notes due April 1, 2020, the $20,611, 6.375% per annum senior notes due March 1, 2021, the $1,854,731, 5.875% per annum senior notes due April 15, 2022, and the $494,344, 8.000% per annum senior notes due April 1, 2023 issued by CONSOL Energy are jointly and severally, and also fully and unconditionally, guaranteed by certain subsidiaries of CONSOL Energy. In accordance with positions established by the Securities and Exchange Commission (SEC), the following financial information sets forth separate financial information with respect to the parent, CNX Gas, a guarantor subsidiary, CNX Coal Resources LP (CNXC), a non-guarantor subsidiary, and the remaining guarantor and non-guarantor subsidiaries. The principal elimination entries include investments in subsidiaries and certain intercompany balances and transactions. CONSOL Energy, the parent, and a guarantor subsidiary manage several assets and liabilities of all other wholly owned subsidiaries. These include, for example, deferred tax assets, cash and other post-employment liabilities. These assets and liabilities are reflected as parent company or guarantor company amounts for purposes of this presentation.

On September 30, 2016, CNXC acquired an additional 5% undivided interest in the Pennsylvania Mining Complex from CONSOL Energy, increasing their total undivided interest to 25%. To account for the acquisition, CNXC recast its consolidated financial statements to retrospectively reflect the additional 5% interest as if the business was owned for all periods presented. This resulted in corresponding retrospective adjustments between the Other Subsidiary Guarantors and the CNXC Non-Guarantor columns below. See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information.

NOTE 25—RELATED PARTY TRANSACTIONS

CONE Gathering LLC and CONE Midstream Partners LP

In September 2011, CNX Gas Company, a wholly owned subsidiary of CONSOL Energy, and Noble Energy, Inc. (Noble Energy), an unrelated third party, formed CONE Gathering LLC (CONE) to develop and operate each company's gas gathering system needs in the Marcellus Shale play. CONSOL Energy accounts for CNX Gas Company's 50% ownership interest in CONE under the equity method of accounting.

In May 2014, CONSOL Energy and Noble Energy (collectively, “the Sponsors”) formed CONE Midstream Partners LP (the Partnership), a master limited partnership, to own, operate, develop and acquire natural gas gathering and other midstream energy assets to service each company’s production in the Marcellus Shale in Pennsylvania and West Virginia. The Partnership's general partner is CONE Midstream GP LLC, a wholly owned subsidiary of CONE.

In September 2014, the Partnership closed its initial public offering of 20,125,000 common units representing limited partnership interests, which included a 2,625,000 common unit over-allotment option that was exercised in full by the underwriters. Following the IPO, CONE had a 2% general partner interest in the Partnership, while each sponsor had a 32.1% limited partner interest. CNX Gas Company accounts for its portion of the earnings in the Partnership under the equity method of accounting.

In November 2016, the Partnership acquired from CONE an additional 25% ownership interest in CONE Midstream DevCo I LP, commonly referred to as the “Anchor Systems.” The transaction included a total purchase consideration of $248,000, comprised of $140,000 in cash and issuance of approximately 5,200,000 common limited partnership units to the Sponsors.  Following the acquisition, CONE continues to have a 2% general partner interest in the Partnership, while each Sponsor’s limited partner interest increased to 33.5%. At December 31, 2016, CNX Gas Company and Noble Energy each continue to own a 50% interest in the assets of CONE that were not contributed to the Partnership.

CNX Coal Resources LP

In July 2015, CNX Coal Resources LP (CNXC) closed its initial public offering of 5,000,000 common units representing limited partnership interests at a price to the public of $15.00 per unit. Additionally, Greenlight Capital entered into a common unit purchase agreement with CNXC pursuant to which Greenlight Capital agreed to purchase, and CNXC agreed to sell, 5,000,000 common units at a price per unit equal to $15.00, which equates to $75,000 in net proceeds. CNXC's general partner is CNX Coal Resources GP, a wholly owned subsidiary of CONSOL Energy. The underwriters of the IPO filing exercised an over-allotment option of 561,067 common units to the public at $15.00 per unit.

In connection with the Initial Public Offering (IPO), CNXC entered into a $400,000 senior secured revolving credit facility with certain lenders and PNC Bank, National Association (PNC), as administrative agent. Obligations under the revolving credit facility are guaranteed by CNXC's subsidiaries (the guarantor subsidiaries) and are secured by substantially all of CNXC's and CNXC's subsidiaries' assets pursuant to a security agreement and various mortgages. Under the new revolving credit facility, CNXC made an initial draw of $200,000, and after origination fees of $3,000, the net proceeds were $197,000.

The total net proceeds related to these transactions that were distributed to CONSOL Energy were $342,711.

In September 2016, CNXC and its wholly owned subsidiary, CNX Thermal Holdings LLC (CNX Thermal), entered into a Contribution Agreement with CONSOL Energy, CONSOL Pennsylvania Coal Company LLC and Conrhein Coal Company (the Contributing Parties) under which CNX Thermal acquired an additional 5% undivided interest in and to the Pennsylvania Mine

Complex, in exchange for (i) cash consideration in the amount of $21,500 and (ii) CNXC's issuance of 3,956,496 Class A Preferred Units representing limited partner interests in CNXC at an issue price of $17.01 per Class A preferred Unit (the "Class A Preferred Unit Issue Price"), or an aggregate $67,300 in equity consideration. The Class A Preferred Unit Issue Price was calculated as the volume-weighted average trading price of CNXC's common units (the "Common Units") over the trailing 15-day trading period ending on September 29, 2016 (or $14.79 per unit), plus a 15% premium.

In connection with the PA Mining acquisition, in September 2016, the General Partner and CNXC entered into the First Amended and Restated Omnibus Agreement (the "Amended Omnibus Agreement") with CONSOL Energy and certain of its subsidiaries. Under the Amended Omnibus Agreement, CONSOL Energy indemnified CNXC for certain liabilities. The Amended Omnibus Agreement also amended CNXC's obligations to CONSOL Energy with respect to the payment of an annual administrative support fee and reimbursement for the provisions of certain management and operating services provided, in each case to reflect structural changes in how those services are provided to CNXC by CONSOL Energy.

During the years ended December 31, 2016, 2015 and 2014, we drilled 36.0, 132.8, and 180.3 net development wells, respectively. There were no net dry development wells in 2016, 2015, or 2014.

During the year ended December 31, 2016, there were no net exploratory wells. During the years ended December 31, 2015 and 2014, we drilled 2.5 and 8.5 net exploratory wells, respectively. There wereno net dry exploratory wells in 2016, 2015, or 2014.

At December 31, 2016, there were 15.0 net development wells and no exploratory wells that have been partially drilled but not turned in-line. Additionally there are 65.5 net developmental wells that are drilled but uncompleted and 3.0 net developmental wells and no net exploratory well that have been completed and are awaiting final tie-in to production.

We are committed to provide 431.4 Bcf of gas under existing sales contracts or agreements over the course of the next four years. We expect to produce sufficient quantities from existing proved developed reserves to satisfy these commitments.

167

Most of our development wells and proved acreage are located in Virginia, West Virginia and Pennsylvania. Some leases are beyond their primary term, but these leases are extended in accordance with their terms as long as certain drilling commitments or other term commitments are satisfied. The following table sets forth, at December 31, 2016, the number of producing wells, developed acreage and undeveloped acreage:

	Gross	Net(1)
Producing Gas Wells (including gob wells)	17,314	12,846
Producing Oil Wells	189	30
Acreage Position:
Proved Developed Acreage	549,816	541,282
Proved Undeveloped Acreage	34,467	30,038
Unproved Acreage	4,804,804	3,745,533
Total Acreage	5,389,087	4,316,853

____________

(1) Net acres include acreage attributable to our working interests of the properties. Additional adjustments (either increases or decreases) may be required as we further develop title to and further confirm our rights with respect to our various properties in anticipation of development. We believe that our assumptions and methodology in this regard are reasonable.

Proved Oil and Gas Reserves Quantities:

Annually, the preparation of natural gas reserves estimates are completed in accordance with CONSOL Energy's prescribed internal control procedures, which include verification of input data into a gas reserves forecasting and economic evaluation software, as well as multi-functional management review. The input data verification includes reviews of the price and cost assumptions used in the economic model to determine the reserves. Also, the production volumes are reconciled between the system used to calculate the reserves and other accounting/measurement systems. The technical employee responsible for overseeing the preparation of the reserve estimates is a petroleum engineer with over 10 years of experience in the oil and gas industry. Our 2016 gas reserves results, which are reported in the Supplemental Gas Data year ended December 31, 2016 Form 10-K, were audited by Netherland, Sewell & Associates, Inc. The technical person primarily responsible for overseeing the audit of our reserves is a registered professional engineer in the state of Texas with over 15 years of experience in the oil and gas industry. The gas reserves estimates are as follows:

__________

(a) Proved developed and proved undeveloped gas reserves are defined by SEC Rule 4.10(a) of Regulation S-X. Generally, these reserves would be commercially recovered under current economic conditions, operating methods and government regulations. CONSOL Energy cautions that there are many inherent uncertainties in estimating proved reserve quantities, projecting future production rates and timing of development expenditures. Proved oil and gas reserves are estimated quantities of natural gas which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions and government regulations. Proved developed reserves are reserves expected to be recovered through existing wells, with existing equipment and operating methods.

(b) Revisions for 2014 are primarily due to efficiencies in operations andwell optimization and had the total effect of positive revisions. Additionally, the 2014 revisions include a reclassification of ethane volumes from natural gas to NGLs.

(c) Extensions and Discoveries in 2014 are primarily due to the addition of wells on our Marcellus and Utica Shale acreage. We also included Marcellus Shale wells which are more than one offset location away due to continued use of reliable technology.

(d) The upward revisions in 2015 are attributable to efficiencies in operations and well performance.

(e) Extensions and Discoveries in 2015 are due mainly to the high grading of locations which resulted in the addition of wells on our Marcellus and Utica Shale acreage more than one offset location away with continued use of reliable technology.

(f) The net downward revisions for 2016 are primarily due to changes in plans related to future locations.

(g) Extensions and Discoveries in 2016 are due to the addition of wells on our Marcellus and Utica Shale acreage more than one offset location away with continued use of reliable technology.

(h) Purchases and Sales of Reserves In-Place in 2016 is the result of our fourth quarter realignment of the Marcellus Shale properties as part of dissolving our joint venture with Noble Energy.

169

(i) Included in our proved developed reserves at December 31, 2016 are producing wells with negative undiscounted cash flows that represent 199.3 Bcfe of natural gas and equivalents which represents 3.2% of our total reserves quantities. These consist primarily of conventional wells and the company includes these wells in our reserves as we continue to produce the properties.

_________

(a) During 2016, various exploration and development drilling and evaluations were completed. Approximately, $58,694 ofcapital was spent in the year ended December 31, 2016 related to undeveloped reserves that were transferred to developed.

(b) Plan and other revisions are due to high grading of locations. These changes along with upward revisions attributable to efficiencies in operations and well performance had the total affect of a positive revision.

(c) Extensions and discoveries are due mainly to the high grading of locations which resulted in the addition of wells on our Marcellus and Utica Shale acreage more than one offset location away with continued use of reliable technology.

(d) Included in proved undeveloped reserves at December 31, 2016 are approximately 215,861 MMcfe of reserves that have been reported for more than five years. These reserves specifically relate to GOB (a rubble zone formed in the cavity created by the extraction of coal) production due to a complex fracture being generated in the overburden strata above the mined seam. Mining operations take a significant amount of time and our GOB forecasts are consistent with the future plans of the Buchanan Mine that was sold in March 2016 to Coronado IV LLC (See Note 2 - Discontinued Operations for more information) with the rights to this gas being retained by the Company. Evidence also exists that supports the continual operation of the mine beyond the current plan, unless there was an extreme circumstance resulting from an external factor. These reasons constitute the specific circumstances that exist to continue recognizing these reserves for CONSOL Energy.

(e) Included in proved undeveloped reserves at December 31, 2016 are 175 gross proved undeveloped locations that generate positive future net revenue but have negative present worth discounted at 10 percent as of December 31, 2016, representing 58.9% of our total proved undeveloped reserves. Additionally, the 1,511.8 Bcfe of natural gas and equivalents attributable to these locations represent approximately 24.2% of our total proved reserves. The Company includes these well sites in its current drilling plans and currently intends to drill these sites as our economic modeling of these well locations generate positive future cash flows.

At December 31, 2016 there were no wells pending the determination of proved reserves.

The following table represents the capitalized exploratory well cost activity as indicated:

	December 31,
	2016		2015		2014

Standardized Measure of Discounted Future Net Cash Flows:

The following information has been prepared in accordance with the provisions of the Financial Accounting Standards Board's Accounting Standards Update No. 2010-03, “Extractive Activities-Oil and Gas (Topic 932).” This topic requires the standardized measure of discounted future net cash flows to be based on the average, first-day-of-the-month price for the year. Because prices used in the calculation are average prices for that year, the standardized measure could vary significantly from year to year based on the market conditions that occurred.

The projections should not be viewed as realistic estimates of future cash flows, nor should the “standardized measure” be interpreted as representing current value to CONSOL Energy. Material revisions to estimates of proved reserves may occur in the future; development and production of the reserves may not occur in the periods assumed; actual prices realized are expected to vary significantly from those used; and actual costs may vary. CONSOL Energy's investment and operating decisions are not based on the information presented, but on a wide range of reserve estimates that include probable as well as proved reserves and on different price and cost assumptions.

The standardized measure is intended to provide a better means for comparing the value of CONSOL Energy's proved reserves at a given time with those of other gas producing companies than is provided by a comparison of raw proved reserve quantities.

(a) For 2016, the reserves were computed using unweighted arithmetic averages of the closing prices on the first day of each month during 2016, adjusted for energy content and a regional price differential. For 2016, this adjusted natural gas price was $1.73 per mcf, the adjusted oil price was $25.04 per barrel and the adjusted NGL price was $15.77 per barrel.

For 2015, the reserves were computed using unweighted arithmetic averages of the closing prices on the first day of each month during 2015, adjusted for energy content and a regional price differential. For 2015, this adjusted natural gas price was $2.02 per mcf, the adjusted oil price was $25.29 per barrel and the adjusted NGL price was $15.59 per barrel.

For 2014, the reserves were computed using unweighted arithmetic averages of the closing prices on the first day of each month during 2014, adjusted for energy content and a regional price differential. For 2014, this adjusted natural gas price was $3.85 per mcf, the adjusted oil price was $77.30 per barrel and the adjusted NGL price was $46.54 per barrel.

______________

* Proven and probable coal reserves are the equivalent of “demonstrated reserves” under the coal resource classification system of the U.S. Geological Survey. Generally, these reserves would be commercially mineable at year-end prices and cost levels, using current technology and mining practices.

(1) 143.3 Million tons for the Mason Dixon Project are controlled by CCC, a former subsidiary of CONSOL Energy that was sold in December 2013. As of filing, these tons are still controlled by CCC but are shown in CONSOL Energy's reserves due to a binding agreement that these tons will be released to CONSOL Energy upon consent of the lessor.

CONSOL Energy's coal reserves are located in nearly every major coal-producing region in North America. Our estimate of proven and probable coal reserves has been determined by CONSOL Energy. At December 31, 2016, 141 million tons were assigned to mines either in production or temporarily idled. The proven and probable coal reserves at December 31, 2016 include 2,274 million tons of thermal coal reserves, of which approximately 2 percent has a sulfur content equivalent to less than 1.2 pounds sulfur dioxide per million British thermal unit (Btu), 8 percent has a sulfur content equivalent to between 1.2 and 2.5 pounds sulfur dioxide per million Btu, and 90 percent has a sulfur content equivalent to greater than 2.5 pounds sulfur dioxide per million Btu. The reserves also include 87 million tons of metallurgical coal in consolidated reserves, of which approximately 24 percent has a sulfur content equivalent to less than 1.2 pounds sulfur dioxide per million Btu and 76 percent has a sulfur content equivalent to between 1.2 and 2.5 pounds sulfur dioxide per million Btu.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure controls and procedures. CONSOL Energy, under the supervision and with the participation of its management, including CONSOL Energy’s principal executive officer and principal financial officer, evaluated the effectiveness of the Company’s “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Act of 1934, as amended (the “Exchange Act”), as of the end of the period covered by this Annual Report on Form 10-K. Based on that evaluation, CONSOL Energy’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures are effective as of December 31, 2016 to ensure that information required to be disclosed by CONSOL Energy in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and includes controls and procedures designed to ensure that information required to be disclosed by CONSOL Energy in such reports is accumulated and communicated to CONSOL Energy’s management, including CONSOL Energy’s principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Management's Annual Report on Internal Control Over Financial Reporting.CONSOL Energy's management is responsible for establishing and maintaining adequate internal control over financial reporting. CONSOL Energy's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

CONSOL Energy's internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets; (2) provide reasonable assurances that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and the directors of CONSOL Energy; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of CONSOL Energy's assets that could have a material effect on our financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of CONSOL Energy's internal control over financial reporting as of December 31, 2016. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (COSO) in Internal Control-Integrated Framework. Based on our assessment and those criteria, management has concluded that CONSOL Energy maintained effective internal control over financial reporting as of December 31, 2016.

The effectiveness of CONSOL Energy's internal control over financial reporting as of December 31, 2016 has been audited by Ernst and Young, an independent registered public accounting firm, as stated in their report set forth in the Report of Independent Registered Public Accounting Firm in Part II, Item 9A of this annual report on Form 10-K.

Changes in internal controls over financial reporting. There were no changes in the Company's internal controls over financial reporting that occurred during the fourth quarter of the fiscal year covered by this Annual Report on Form 10-K that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of CONSOL Energy Inc. and Subsidiaries

We have audited CONSOL Energy Inc. and Subsidiaries' internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). CONSOL Energy Inc. and Subsidiaries' management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, CONSOL Energy Inc. and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based onthe COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of CONSOL Energy Inc. and Subsidiaries as of December 31, 2016 and 2015, and the related consolidated statements of income, comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2016 of CONSOL Energy Inc. and Subsidiaries and our report dated February 8, 2017 expressed an unqualified opinion thereon.

Noble and CONSOL may be referred to collectively as the “Parties” or individually as a “Party.” Capitalized terms used herein but not defined shall have the meanings ascribed to them in the Exchange Agreement (as defined below).

WHEREAS, Seller and Purchaser entered into that certain Exchange Agreement dated as of October 29, 2016 (the “Exchange Agreement”); and

WHEREAS, the Parties desire to amend the Exchange Agreement, as set forth herein.

2.Section 12.2(g) of the Exchange Agreement is hereby deleted in its entirety and replaced in its entirety with the following:

“Within 30 days after the last day of the calendar month in which the Closing occurs both CONSOL and Noble agree to file “well transfer requests” with respect to each well included in the CONSOL Transferred Assets or the Noble Transferred Assets in the Pennsylvania Public Utility Commission (PUC) Act 13 online system and each Non-Transferring Party agrees to include the transferred wells on its “annual report” with the PUC and to pay any related impact fees, subject to such Party’s right of reimbursement under Section 12.2(f).”

3.The definition of “Specified Defects” shall be amended by adding to the end of the definition the following:

“or (viii) being a Conceded Title Defect under Section 2 of that certain Agreement attached hereto as Exhibit P. To the extent that any shortage of Net Acres is provided for under one of the subsections of this definition, such shortage of Net Acres cannot be claimed under another subsection of this definition.”

4.Appendix I to the Exchange Agreement is hereby amended to add a new defined term after the term “Assignment” and before the term “Benefit Net Acres Claim”:

““Available Credit Amount” means, as of the time of calculation, the difference between the Credit Amount less any amounts offset against the Credit Amount pursuant to Section 6.8(d) prior to such time of calculation.”

5.Appendix I to the Exchange Agreement is hereby amended to add a new defined term after the term “Control” and before the term “Customary Post Closing Consents”:

““Credit Amount” means an amount equal to $1,599,750.”

6.Section 6.8 of the Exchange Agreement is hereby amended by adding a new subjection (d) thereto as follows:

“(d)     To the extent that CONSOL is required to make a cash payment to Noble with respect to a Deficiency Net Acres Claim pursuant to Section 6.8(a)(iv), then in lieu of making such cash payment, CONSOL shall have the right to offset any such amounts owed by CONSOL to Noble against the Credit Amount until such time that the Available Credit Amount is equal to $0.00. At such time that the Available Credit Amount is equal to $0.00, if CONSOL is required to make any payments to Noble with respect to a Deficiency Net Acres Claim pursuant to Section 6.8(a)(iv), CONSOL shall again be required to make such payments in cash. On the first anniversary of the Closing, if the Available Credit Amount is greater than $0.00, Noble shall be required to make a cash payment to CONSOL equal to the then positive balance of the Available Credit Amount on such date.”

Brock (the "Executive").

WITNESSETH:

WHEREAS, CONSOL and the Executive previously entered into a Change in Control Severance Agreement dated as of August 24, 2015, which agreement the parties wish to amend and restate to reflect the Executive’s retention by CONSOL; and

WHEREAS, the Executive is a senior executive of the General Partner and has made and is expected to continue to make major contributions to the short- and long-term profitability, growth and financial strength of the CONSOL Companies; and

WHEREAS, the Board (as defined below) and the board of directors of CONSOL (the “CONSOL Board”) recognize that, as is the case with many publicly held corporations, the possibility of a Change in Control (as defined below) exists and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of key management personnel to the detriment of the Company and its equity owners; and

WHEREAS, the Board and the CONSOL Board have determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the Company's management, including the Executive, to their assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a Change in Control; and

WHEREAS, in consideration of the Executive's continued employment with CPCC and service to the General Partner for the benefit of the Company and CONSOL, and the Executive's agreement to waive certain rights the Executive may have to receive severance compensation and benefits under any applicable severance plan or policy of any of the CONSOL Companies, as set forth below, the CONSOL Companies desire to provide the Executive with certain compensation and benefits set forth in this Agreement in order to ameliorate the financial and career impact on the Executive in the event the Executive's employment with the CONSOL Companies (or their respective Subsidiaries) is terminated for a reason related to a Change in Control; and

WHEREAS, the Executive agrees to waive any rights the Executive may have under any CONSOL Company severance plan, policy or other agreement with respect to severance compensation and benefits in the event the Executive's employment with CPCC and/or office with the CONSOL Companies is terminated as the result of an Involuntary Termination Associated With a Change in Control (as defined below).

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements hereinafter set forth and intending to be legally bound hereby, the General Partner, CPCC, CONSOL and the Executive agree as follows:

1.Certain Defined Terms. In addition to terms defined elsewhere herein, the following terms have the following meanings when used in this Agreement with initial capital letters:

(a)"Base Pay" means the greater of (i) the Executive's annual base salary rate, exclusive of bonuses, commissions and other Incentive Pay, as in effect immediately preceding the Executive's Termination Date, or (ii) the Executive's annual base salary rate, exclusive of bonuses, commissions and other Incentive Pay, as in effect immediately prior to the Change in Control.

(b)"Board" means the Board of Directors of the General Partner.If the Executive is also a member of the Board, then in the case of any provision hereof that requires action by, or a determination of, the Board in connection with this Agreement, it is understood that such provision refers to the members of the Board other than the Executive.

(c)"Cause" means a determination by the Board or the CONSOL Board that the Executive has committed any of the following acts:

(i)the Executive has been convicted of, or the Executive has pleaded guilty or nolo contendere to, (A) any felony, or (B) any misdemeanor involving fraud, embezzlement or theft; or

(ii)the Executive has wrongfully disclosed material confidential information of any CONSOL Company and/or any of their respective Subsidiaries, has intentionally violated any material express provision of the Company's or CONSOL’s code of conduct for executives and management employees (as in effect on the date of the Change in Control), or has intentionally failed or refused to perform any of the Executive’s material assigned duties for any CONSOL Company; and any such failure or refusal has been demonstrably and materially harmful to the Company.

Notwithstanding the foregoing, the Executive will not be deemed to have been terminated for "Cause" under this subsection (ii) unless and until there has been delivered to the Executive a copy of a resolution duly adopted by the affirmative vote of not less than the majority of the members of the Board or the CONSOL Board plus one member, finding that, in the good faith opinion of such board, the Executive has committed an act constituting "Cause," as herein defined, and specifying the particulars thereof in detail. Prior to any such determination, the Executive shall be provided with reasonable notice of such pending determination and the Executive, together with the Executive’s counsel (if the Executive chooses to have counsel present at such meeting), shall be provided with the opportunity to be heard before such board makes any such determination.

2.Termination Associated With a Change in Control.

(a)Involuntary Termination Associated With a Change in Control. In the event the Executive's employment is terminated after, or in connection with, a Change in Control, on account of (i) an Involuntary Termination Associated With a Change in Control within the two year period after the Change in Control, or (ii) an involuntary termination (other than for Cause or due to the Executive's death or Disability) that (A) occurs not more than three (3) months prior to the date on which a Change in Control occurs, or (B) is requested by a third party who initiates a Change in Control, the Executive shall be entitled to the benefits provided in subsection (b) of this Section 2. For purposes of subsection 2(a)(ii)(B) above, to be eligible to receive amounts described in Section 2(b) below, a Change in Control must be consummated within the twelve (12) month period following the Executive's Termination Date, except in circumstances pursuant to which the consummation of the Change in Control is delayed, through no failure of the CONSOL Companies or the acquiring company, by a governmental or regulatory authority or agency with jurisdiction over the matter, or as a result of other similar circumstances where a third party approval is necessary and is delayed. In such a circumstance, the remainder of the twelve (12) month period shall be tolled and shall recommence upon termination of the delaying event.

(b)Compensation and Benefits Upon Involuntary Termination Associated With a Change in Control. In the event a termination described in subsection (a) of this Section 2 occurs, and subject to the Executive’s compliance with the provisions of Section 4 hereof, CPCC, CONSOL and the General Partner (collectively) shall pay and provide to the Executive after the Executive’s Termination Date:

(i)A lump sum cash payment equal to (A) 2.0 times Base Pay, plus(B) 2.0 timesIncentive Pay.

(ii)The Executive shall receive a pro rated payment of the Executive’s Incentive Pay for the year in which the Executive’s Termination of Employment occurs. The pro rated payment shall be based on the Executive's Incentive Pay as of the Executive's Termination Date, multiplied by a fraction, the numerator of which is the number of days during which the Executive was employed by the CONSOL Company in the year of the Executive’s termination and the denominator of which is 365.

(iii)For the 18 month period immediately following the Date of Termination or, if later, the closing dates for the Change in Control:

(A)    If the Executive elects COBRA Continuation Coverage, the Executive shall continue to participate in all medical, dental and vision insurance plans the Executive was participating in on the Termination Date, and CONSOL, CPCC, and

7

the General Partner shall pay the applicable premium. During the applicable period of coverage described in the foregoing sentences, the Executive shall be entitled to benefits on substantially the same basis and cost as would have otherwise been provided had the Executive not separated from service. To the extent that such benefits are available under the above-referenced benefit plans and the Executive had such coverage immediately prior to termination of employment, such continuation of benefits for the Executive shall also cover the Executive's dependents for so long as the Executive is receiving benefits under this paragraph (iii). The COBRA Continuation Period for medical and dental insurance under this paragraph (iii) shall be deemed to run concurrent with the continuation period federally mandated by COBRA (generally 18 months), or any other legally mandated and applicable federal, state, or local coverage period for benefits provided to terminated employees under the health care plan. For purposes of this Agreement, "COBRA" means the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended; and "COBRA Continuation Period" shall mean the continuation period for medical and dental insurance to be provided under the terms of this Agreement which shall commence on the first day of the calendar month following the month in which the date of termination falls and generally shall continue for an 18 month period.

(iv)If the Executive would have been eligible for post-retirement medical and dental coverage had the Executive retired from employment during the period of 18 months following the Executive’s Termination Date, but is not so eligible as the result of the Executive’s termination, then, at the conclusion of the benefit continuation period described in (iii) above, CONSOL, CPCC and the General Partner shall take all commercially reasonable efforts to provide the Executive with additional continued group medical and dental coverage comparable to that which would have been available to the Executive from time to time under the post-retirement medical and dental benefit program, for as long as such coverage would have been available under such program. It is specifically acknowledged by the Executive that if such coverage is provided under a CONSOL sponsored self insured plan, it will be provided on an after-tax basis and the Executive will have income imputed to the Executive annually equal to the fair market value of the premium. If this coverage cannot be provided by CONSOL, CPCC and the General Partner, (or where such continuation would adversely affect the tax status of the plan pursuant to which the coverage is provided), then as an alternative, CONSOL, CPCC and the General Partner will reimburse the Executive in lieu of such coverage an amount equal to the Executive's actual and reasonable after-tax cost of continuing comparable coverage.

Reimbursement to the Executive pursuant to subsections (iii) or (iv) above will be available only to the extent that (1) such expense is actually incurred for any particular calendar year and reasonably substantiated; (2) reimbursement shall be made no later than the end of the calendar year following the year in which such expense is incurred by the Executive; (3) no reimbursement provided for any expense incurred in one taxable year will affect the amount available in another taxable year; and (4) the right to this reimbursement is not subject to liquidation or exchange for another benefit. Notwithstanding the foregoing, under subsection (iii), no reimbursement will be provided for any expense incurred following the 18 months or for any expense which relates to coverage after such date.

(v)A lump sum cash payment equal to the total amount that the Executive would have received under CONSOL’s, CPCC’s or the General Partner’s 401(k) plan as a company match if the Executive was eligible to participate in such 401(k) plan for the 18 month period after the Executive’s Termination Date and the Executive contributed the maximum

8

amount to the plan for the match. Such amount shall be determined based on the assumption that the Executive would have received annual Base Pay plus Incentive Pay during such period in the amounts set forth in Sections 2(b)(i) and (ii) above.

(vi)A lump sum cash payment equal to the difference between the present value of the Executive's accrued pension benefits at the Executive’s Termination Date under CONSOL’s, CPCC’s or the General Partner 's qualified defined benefit plan and (if eligible) any plan or plans sponsored by CONSOL, CPCC or the General Partner providing nonqualified retirement benefits (which currently includes the CONSOL Energy Inc. Defined Contribution Restoration Plan) (the qualified and nonqualified plans together being referred to as the "pension plans") and the present value of the accrued pension benefits to which the Executive would have been entitled under the pension plans if the Executive had continued participation in those plans for the 18 month period after the Executive’s Termination Date. Such amount shall be determined based on the assumption that the Executive would have received annual Base Pay plus Incentive Pay during such period in the amounts set forth in Sections 2(b)(i) and (ii) above.

(vii)A lump sum cash payment of $25,000 in order to cover the cost of outplacement assistance services for the Executive and other expenses associated with seeking another employment position.

(viii)The Executive shall receive any amounts earned, accrued or owing but not yet paid to the Executive as of the Executive’s Termination Date, payable in a lump sum, and any benefits accrued or earned in accordance with the terms of any applicable benefit plans and programs of CONSOL, CPCC and the General Partner.

(ix)All payments under this subsection 2(b) will be made in a lump sum no later than 60 days after the date of termination (or, if later, the closing date of the Change in Control, as applicable); provided, however, that the benefits due under subsections (iii) and (iv) shall be provided as specified thereunder.

(c)Vesting of Equity Rights. Notwithstanding any provision to the contrary in any applicable plan, program or agreement, upon the occurrence of a Change in Control, all stock options, stock appreciation rights, restricted stock, restricted stock units and other equity rights awarded by the General Partner and/or CONSOL in Company and/or CONSOL equity and held by the Executive will become fully vested and/or exercisable, as the case may be, on the date on which the Change in Control occurs, and all stock options or stock appreciation rights held by the Executive shall remain exercisable for the period set forth in the award agreement covering the options or rights.

(d)Consultancy Period Option. Except in the event CONSOL exercises its reemployment rights set forth in Section 2(e) hereof, in the case of any Involuntary Termination Associated With a Change in Control, CONSOL, CPCC or the General Partner may, in its sole discretion, elect to require reasonable cooperation from the Executive following the Executive's Termination Date for a period (the "Consultancy Period") not to exceed 18 months. In the event of such election, the Executive shall, during the pendency of the Consultancy Period, be available from time to time, at the request of CONSOL, CPCC or the General Partner’s Chairman of the Board or Chief Executive Officer, to provide advice and assistance concerning (i) the transition of the Executive's duties and responsibilities to any successor to the Executive’s position, and (ii) any other matters concerning CONSOL’s, CPCC’s or the General Partner’s corporate, business and financial affairs which are consistent with the Executive's expertise and experience. Such advice and assistance may, at the Executive's option, be provided either in

9

person or by telephone or videoconference. In no event shall CONSOL, CPCC or the General Partner request, nor shall the Executive be required to provide more than five (5) hours of consulting services per work week, nor to provide such services other than during normal business hours. The Executive shall be reimbursed by CONSOL, CPCC or the General Partner any reasonable expenses incurred in connection with the performance of such services, subject to compliance with CONSOL's standard policies and procedures regarding reimbursement of expenses. The Executive shall be permitted, during the Consultancy Period, to engage in other business and personal activities; provided, that such activities are not inconsistent with the Executive's duties under Sections 9 and 10 hereof.

(e)CONSOL Reemployment Option. In the case of any Involuntary Termination Associated With a Change in Control (other than a Change in Control within the meaning of Section 1(d)(ii)), CONSOL may, in its sole discretion, elect on or before the 30th day following the Executive’s Termination Date, to reemploy the Executive, effective as of the Executive’s Termination Date, on a full-time basis in a salaried employment position. In the event that CONSOL elects to reemploy the Executive as described above, then the Executive shall be entitled to receive generally comparable annual base salary, Incentive Pay and Employee Benefits from CONSOL for a period not extending beyond the two year anniversary of the Change in Control (the “Reemployment Period”). If the Executive refuses or fails to accept CONSOL’s offer of reemployment, subject to such terms, conditions and agreements as CONSOL may require, the Executive shall not be considered to have terminated employment under this Agreement and shall not receive benefits pursuant to Section 2 hereof.

Upon any such reemployment, the Executive hereby agrees that (i) no compensation and benefits shall be payable to the Executive under this Agreement except for CONSOL’s obligations under this Section 2(e) during the Reemployment Period, and (ii) the Executive shall agree to terminate this Agreement with the CONSOL Companies (except as provided in Section 20 hereof) and execute a change in control agreement and a noncompete, nonsolicitation and nondisclosure agreement in such form(s) satisfactory to, and provided by, CONSOL. In the event that CONSOL subsequently terminates the Executive during the Reemployment Period, CONSOL shall pay to the Executive the benefits provided under Section 2(b) (as determined on the date of the Change in Control); provided, however, that (i) the amount payable upon the Executive’s termination under (b)(i) and (b)(ii) above shall be reduced by the amount of salary and Incentive Pay received by the Executive during the Reemployment Period, and (ii) the periods applicable under (b)(iii), (b)(iv), (b)(v) and (b)(vi) above shall be reduced by the number of months the Executive was employed by CONSOL during the Reemployment Period.

3.Termination of Employment on Account of Disability, Cause or Death. Notwithstanding anything in this Agreement to the contrary, if the Executive's employment terminates on account of Disability, the Executive shall be entitled to receive disability benefits under any disability program maintained by CONSOL, CPCC or the General Partner that covers the Executive, and the Executive shall not be considered to have terminated employment under this Agreement and shall not receive benefits pursuant to Section 2 hereof. If the Executive's employment terminates on account of Cause or because of the Executive’s death, the Executive shall not be considered to have terminated employment under this Agreement and shall not receive benefits pursuant to Section 2 hereof.

4.Release. To receive the consideration described in Section 2(b) of this Agreement, the Executive must sign a Separation of Employment and General Release Agreement, substantially in the form attached hereto as Annex A (the "Release"), deliver the signed Release to CONSOL’s General Counsel and the General Partners’s General Counsel within thirty (30) days after the Termination Date (unless a longer period is required by law), and not revoke the Release within the seven-day revocation period provided for in the Release. In the event that CONSOL elects to reemploy the Executive as

10

contemplated in Section 2(e), then the payment of compensation, incentive pay and benefits contemplated under Sections 2(b) and 2(e) shall be subject, at CONSOL's election, to the Executive's execution and non-revocation of a Release at the time the Reemployment Period commences and the Executive's renewal of such Release, and non-revocation of such renewal, at the time of any subsequent termination during the Reemployment Period.

5.Enforcement. Without limiting the rights of the Executive at law or in equity, if CONSOL, CPCC or the General Partner fails to make any payment or provide any benefit required to be made or provided hereunder on a timely basis, CONSOL, CPCC or the General Partner will pay interest on the amount or value thereof at an annualized rate of interest equal to the so-called composite "prime rate" as quoted from time to time during the relevant period in the Eastern Edition of The Wall Street Journal. Such interest will be payable as it accrues on demand. Any change in such prime rate will be effective on and as of the date of such change.

6.Limit on Payments by the CONSOL Companies.

(a)The provisions of this Section 6 shall apply notwithstanding anything in this Agreement or any other agreement to the contrary. In the event that it shall be determined that any payment or distribution by the CONSOL Companies to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (a "Payment"), would constitute an "excess parachute payment" within the meaning of Section 280G of the Code, CONSOL Companies will apply a limitation on the Payment amount as set forth below (a "Parachute Cap") as follows: The aggregate present value of the Payments under Section 2(b) of this Agreement ("Agreement Payments") shall be reduced (but not below zero) to the Reduced Amount; provided, however, that any such reduction shall be applied to Agreement Payments that do not constitute deferred compensation and are exempt or otherwise excepted from coverage under Section 409A (but excluding stock options or other stock rights). The "Reduced Amount" shall be an amount expressed in present value which maximizes the aggregate present value of Agreement Payments without causing any Payment to be subject to the limitation of deduction under Section 280G of the Code. For purposes of this Section 6, "present value" shall be determined in accordance with Section 280G(d)(4) of the Code.

(b)Except as set forth in the next sentence, all determinations to be made under this Section 6 shall be made by the nationally recognized independent public accounting firm used by the Company immediately prior to the Change in Control ("Accounting Firm"), which Accounting Firm shall provide its determinations and any supporting calculations to the Company and the Executive within ten (10) days of the Executive's Termination Date. The value of the Executive's non-competition covenant under Section 10(a) of this Agreement shall be determined by independent appraisal by a nationally-recognized business valuation firm acceptable to the Executive, CONSOL and the General Partner, and a portion of the Agreement Payments shall, to the extent of that appraised value, be specifically allocated as reasonable compensation for such non-competition covenant and shall not be treated as a parachute payment. Any such determination by the Accounting Firm shall be binding upon the Company and the Executive.

(c)All of the fees and expenses of the Accounting Firm in performing the determinations referred to in this Section 6 shall be borne solely by the CONSOL Companies.

7.No Mitigation Obligation. The CONSOL Companies hereby acknowledges that it will be difficult and may be impossible for the Executive to find reasonably comparable employment following the Termination Date. Accordingly, the payment of the severance compensation by the CONSOL

11

Companies to the Executive in accordance with the terms of this Agreement is hereby acknowledged by the CONSOL Companies to be reasonable, and the Executive will not be required to mitigate the amount of any payment provided for in this Agreement by seeking other employment or otherwise, nor will any profits, income, earnings or other benefits from any source whatsoever create any mitigation, offset, reduction or any other obligation on the part of the Executive hereunder or otherwise. Notwithstanding anything to the contrary contained herein, as a condition to accepting benefits provided hereunder, the Executive will be required to waive, and will be deemed to have waived, any other right or entitlement to severance or termination benefits from the CONSOL Companies or their Subsidiaries.

8.Legal Fees and Expenses. In the event of a Change in Control, it is the intent of the CONSOL Companies that the Executive not be required to incur legal fees and the related expenses associated with the interpretation, enforcement or defense of the Executive's rights under this Agreement by litigation or otherwise because the cost and expense thereof would detract from the benefits intended to be extended to the Executive hereunder. Accordingly, if a Change in Control occurs and it should appear to the Executive that any of the CONSOL Companies has failed to comply with any of its obligations under this Agreement or in the event that any of the CONSOL Companies or any other person takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other action or proceeding designed to deny, or to recover from, the Executive the benefits provided or intended to be provided to the Executive under Section 2 of this Agreement, the CONSOL Companies irrevocably authorizes the Executive from time to time to retain counsel of the Executive's choice, at the expense of the CONSOL Companies as hereafter provided, to advise and represent the Executive in connection with any such interpretation, enforcement or defense, including without limitation the initiation or defense of any litigation or other legal action, whether by or against the CONSOL Companies or any Director, officer or employee of any of the CONSOL Companies, in any jurisdiction. Notwithstanding any existing or prior attorney-client relationship between any of the CONSOL Companies and such counsel, each of the CONSOL Companies irrevocably consents to the Executive's entering into an attorney-client relationship with such counsel, and in that connection, the CONSOL Companies and the Executive agree that a confidential relationship will exist between the Executive and such counsel. Without respect to whether the Executive prevails, in whole or in part, in connection with any of the foregoing, the CONSOL Companies will pay and be solely financially responsible for any and all reasonable attorneys' and related fees and expenses incurred by the Executive in connection with any of the foregoing; provided that, in regard to such matters, the Executive has not acted frivolously, in bad faith or with no colorable claim of success. Such fees and expenses will be paid by the CONSOL Companies as they are incurred by the Executive, but in no event later than the end of the Executive's taxable year following the Executive's taxable year in which the Executive incurs the fees and expenses. In addition, no reimbursement provided for any expense incurred in one taxable year will affect the amount available in another taxable year, and the right to this reimbursement is not subject to liquidation or exchange for another benefit.

9.Confidentiality. The Executive hereby covenants and agrees that, except as specifically requested or directed by the CONSOL Companies, the Executive will not disclose to any person not employed by the CONSOL Companies, or use in connection with engaging in competition with the CONSOL Companies, any confidential or proprietary information (as defined below) of the CONSOL Companies. For purposes of this Agreement, the term "confidential or proprietary information" will include all information of any nature and in any form that is owned by the CONSOL Companies and that is not publicly available (other than by the Executive's breach of this Section 9) or generally known to persons engaged in businesses similar or related to those of the CONSOL Companies. Confidential or proprietary information will include, without limitation, the CONSOL Companies' financial matters, customers, employees, industry contracts, strategic business plans, product development (or other

12

proprietary product data), marketing plans, consulting solutions and processes, and all other secrets and all other information of a confidential or proprietary nature which is protected by the Uniform Trade Secrets Act. For purposes of the preceding two sentences, the term "CONSOL Companies" will also include any Subsidiary of any CONSOL Company (collectively, the "Restricted Group"). The foregoing obligations imposed by this Section 9 will not apply (i) in the course of the business of and for the benefit of the CONSOL Companies, (ii) if such confidential or proprietary information has become, through no fault of the Executive, generally known to the public, or (iii) if the Executive is required by law to make disclosure (after giving the CONSOL Companies notice and an opportunity to contest such requirement).

Notwithstanding the foregoing, nothing in this Agreement restricts or prohibits the Executive from reporting possible violations of law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or from making other disclosures that are protected under state or federal law or regulation. The Executive does not need the prior authorization of the CONSOL Companies to make such reports or disclosures. The Executive is not required to notify the CONSOL Companies that the Executive has made any such reports or disclosures.

10.Covenants Not to Compete and Not to Solicit. In the event of the Executive's Termination of Employment, the CONSOL Companies' obligations to provide the payments and benefits set forth in Section 2 shall be expressly conditioned upon the Executive's compliance with the covenants not to compete and not to solicit as provided herein. In the event the Executive breaches the Executive’s obligations to the CONSOL Companies as provided herein, the CONSOL Companies' obligations to provide the payments and benefits set forth in Section 2 shall cease, without prejudice to any other remedies that may be available to the CONSOL Companies. For purposes of this Section 10 and the definition of “Restricted Business” and “Restricted Territory” as used herein, the term “CONSOL Companies” will also include any Subsidiary of any CONSOL Company.

(a)Covenant Not to Compete. If the Executive is receiving payments and benefits under Section 2 above (or subsequently becomes entitled thereto because of a termination described in Section 2(a)(ii)), then, for a period of one (1) year following the Executive's Termination Date, the Executive shall not directly or indirectly engage in (whether as an employee, consultant, proprietor, partner, director or otherwise), or have any ownership interest in, or participate in a financing, operation, management or control of, any person, firm, corporation or business that is a Restricted Business in a Restricted Territory without the prior written consent of the Board. For this purpose, ownership of no more than 5% of the outstanding Voting Stock of a publicly traded corporation shall not constitute a violation of this provision.

(b)Covenant Not to Solicit. If the Executive is receiving payments and benefits under Section 2 above (or subsequently becomes entitled thereto because of a termination described in Section 2(a)(ii)), then, for a period of two (2) years following the Executive's Termination Date, the Executive shall not: (i) solicit, encourage or take any other action which is intended to induce any other employee of the CONSOL Companies to terminate the Executive’s employment with the CONSOL Companies; or (ii) interfere in any manner with the contractual or employment relationship between the CONSOL Companies and any such employee of the CONSOL Companies. The foregoing shall not prohibit the Executive or any entity with which the Executive may be affiliated from hiring a former employee of the CONSOL Companies; provided, that such hiring results exclusively from such former employee's affirmative response to a general recruitment effort.

13

(c)Interpretation. The covenants contained herein are intended to be construed as a series of separate covenants, one for each county, town, city and state or other political subdivision of a Restricted Territory. Except for geographic coverage, each such separate covenant shall be deemed identical in terms to the covenant contained in the preceding subsections. If, in any judicial proceeding, the court shall refuse to enforce any of the separate covenants (or any part thereof) deemed included in such subsections, then such unenforceable covenant (or such part) shall be deemed to be eliminated from this Agreement for the purpose of those proceedings to the extent necessary to permit the remaining separate covenants (or portions thereof) to be enforced.

(d)Reasonableness. In the event that the provisions of this Section 10 shall ever be deemed to exceed the time, scope or geographic limitations permitted by applicable laws, then such provisions shall be reformed to the maximum time, scope or geographic limitations, as the case may be, permitted by applicable laws.

11.Employment Rights. Nothing expressed or implied in this Agreement will create any right or duty on the part of the CONSOL Companies or the Executive to have the Executive remain in the employment of the CONSOL Companies or any Subsidiary of any CONSOL Company prior to or following any Change in Control.

12.Withholding of Taxes. The CONSOL Companies and their respective Subsidiaries may withhold from any amounts payable under this Agreement all federal, state, city or other taxes as such party is required to withhold pursuant to any applicable law, regulation or ruling.

13.Term of Agreement. The term of this Agreement shall commence on the Effective Date hereof and shall continue until December 31, 2017; provided, however, that commencing on January 1, 2018, and each January 1 thereafter, the term of this Agreement shall automatically be extended until the following December 31, unless CONSOL, CPCC or the General Partner gives notice not later than October 31 of the preceding year that it does not wish to extend this Agreement; and provided, further, that regardless of any such notice, this Agreement shall continue in effect for a period of 18 months beyond the term provided herein if a Change in Control occurs during the period that this Agreement is in effect.

14.Successors and Binding Agreement.

(a)The General Partner, CPCC and CONSOL will require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization or otherwise) to all or substantially all of the business or assets of CPCC, the Company or CONSOL, by agreement in form and substance reasonably satisfactory to the Executive, expressly to assume and agree to perform this Agreement in the same manner and to the same extent the CONSOL Companies would be required to perform if no such succession had taken place. This Agreement will be binding upon and inure to the benefit of the CONSOL Companies and any successor thereto, including without limitation any persons acquiring directly or indirectly all or substantially all of the business or assets of such parties whether by purchase, merger, consolidation, reorganization or otherwise (and such successor will thereafter be deemed, as applicable, “CPCC”, the “General Partner’ "Company" and/or CONSOL for the purposes of this Agreement), but will not otherwise be assignable, transferable or delegable by the CPCC, the General Partner, the Company or CONSOL.

(b)This Agreement will inure to the benefit of and be enforceable by the Executive's personal or legal representatives, executors, administrators, successors, heirs, distributees and legatees.

14

This Agreement will supersede the provisions of any employment or other agreement between the Executive and one or more of the CONSOL Companies that relate to any matter that is also the subject of this Agreement, and such provisions in such other agreements will be null and void.

(c)This Agreement is personal in nature and neither of the parties hereto will, without the consent of the other, assign, transfer or delegate this Agreement or any rights or obligations hereunder except as expressly provided in Sections 14(a) and (b). Without limiting the generality or effect of the foregoing, the Executive's right to receive payments hereunder will not be assignable, transferable or delegable, whether by pledge, creation of a security interest, or otherwise, other than by a transfer by the Executive's will or by the laws of descent and distribution and, in the event of any attempted assignment or transfer contrary to this Section 14(c), the CONSOL Companies will have no liability to pay any amount so attempted to be assigned, transferred or delegated.

15.Notices. For all purposes of this Agreement, all communications, including without limitation, notices, consents, requests or approvals, required or permitted to be given hereunder will be in writing and will be deemed to have been duly given when hand delivered or dispatched by electronic facsimile transmission (with receipt thereof orally confirmed by the recipient), or five (5) business days after having been mailed by United States registered or certified mail, return receipt requested, postage prepaid, or three (3) business days after having been sent by a nationally recognized courier service for overnight/next-day delivery, such as FedEx, UPS, or the United States Postal Service, addressed to the CONSOL Companies (to the attention of the Secretary of CONSOL and the Secretary of the General Partner) at its principal executive office and to the Executive at the Executive’s principal residence, or to such other address as any party may have furnished to the other in writing and in accordance herewith, except that notices of changes of address will be effective only upon receipt.

16.Governing Law. The validity, interpretation, construction and performance of this Agreement will be governed by and construed in accordance with the substantive laws of the Commonwealth of Pennsylvania, without giving effect to the principles of conflict of laws of such Commonwealth.

17.Validity. If any provision of this Agreement or the application of any provision hereof to any person or circumstances is held invalid, unenforceable or otherwise illegal, the remainder of this Agreement and the application of such provision to any other person or circumstances will not be affected, and the provision so held to be invalid, unenforceable or otherwise illegal will be reformed to the extent (and only to the extent) necessary to make it enforceable, valid or legal.

18.Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in a writing signed by the Executive, CPCC, the General Partner and CONSOL. No waiver by either party hereto at any time of any breach by the other party hereto or compliance with any condition or provision of this Agreement to be performed by such other party will be deemed a waiver of similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, expressed or implied with respect to the subject matter hereof have been made by either party that are not set forth expressly in this Agreement. References to Sections are to references to Sections of this Agreement. Any reference in this Agreement to a provision of a statute, rule or regulation will also include any successor provision thereto. Whenever used herein, the masculine includes the feminine.

15

19.Code Section 409A.

(a)    If any benefit provided under this Agreement is subject to the provisions of Section 409A of the Code and the regulations issued thereunder, the provisions of the Agreement shall be administered, interpreted and construed in a manner necessary to comply with Section 409A and the regulations issued thereunder (or disregarded to the extent such provision cannot be so administered, interpreted, or construed).

(b)    Severance benefits are payable only if the Executive is involuntarily terminated by the CONSOL Companies as provided under this Agreement. For purposes of the Agreement, the Executive shall be considered to have experienced a termination of employment only if the Executive has terminated employment with the CONSOL Companies and all of their controlled group members within the meaning of Section 409A of the Code. For purposes hereof, the determination of controlled group members shall be made pursuant to the provisions of Section 414(b) and 414(c) of the Code; provided that the language "at least 50 percent" shall be used instead of "at least 80 percent" in each place it appears in Section 1563(a)(1), (2) and (3) of the Code and Treas. Reg. § 1.414(c)-2. Whether the Executive has terminated employment will be determined based on all of the facts and circumstances and in accordance with the guidance issued under Section 409A of the Code.

(c)    For purposes of Section 409A, each severance benefit payment shall be treated as a separate payment. Each payment under this Agreement is intended to be excepted from Section 409A to the maximum extent provided under Section 409A as follows: (i) each payment that is scheduled to be made on or before March 15th of the calendar year following the calendar year containing the Executive's termination date (or, if later, the closing date of the Change in Control) is intended to be excepted under the short-term deferral exception as specified in Treas. Reg. § 1.409A-1(b)(4); (ii) post-termination medical benefits are intended to be excepted under the medical benefits exceptions as specified in Treas. Reg. § 1.409A-1(b)(9)(v)(B); and (iii) each payment that is not otherwise excepted under the short-term deferral exception or medical benefits exception is intended to be excepted under the involuntary pay exception as specified in Treas. Reg. § 1.409A-1(b)(9)(iii). The Executive shall have no right to designate the date of any payment under this Agreement.

With respect to payments subject to Section 409A of the Code (and not excepted therefrom), if any, it is intended that each payment is paid on permissible distribution event and at a specified time consistent with Section 409A of the Code. CONSOL, CPCC and the General Partner reserve the right to accelerate and/or defer any payment to the extent permitted and consistent with Section 409A.  Notwithstanding any provision of this Agreement to the contrary, to the extent that a payment hereunder is subject to Section 409A of the Code (and not excepted therefrom) and payable on account or a termination of employment, such payment shall be delayed for a period of six months after the date of termination (or, if earlier, the death of the Executive)if the Executive is a "specified employee" (as defined in Section 409A of the Code and determined in accordance with the procedures established by CONSOL, CPCC or the General Partner). Any payment that would otherwise have been due or owing during such six-month period will be paid immediately following the end of the six-month period in the month following the month containing the six (6)-month anniversary of the date of termination.

20.Survival. Notwithstanding any provision of this Agreement to the contrary, the parties' respective rights and obligations under Sections 2, 6, 8, 9, and 10 will survive any termination or expiration of this Agreement or the termination of the Executive's employment for any reason whatsoever.

16

21.Counterparts. This Agreement may be executed in one or more counterparts, each of which will be deemed to be an original but all of which together will constitute one and the same agreement.

SEPARATION OF EMPLOYMENT AND GENERAL RELEASE AGREEMENT

THIS SEPARATION OF EMPLOYMENT AGREEMENT AND GENERAL RELEASE (the "Agreement") is made as of this _____ day of __________, _____, by and between CONSOL Pennsylvania Coal Company LLC, CNX Coal Resources GP LLC, the General Partner of CNX Coal Resources LP and CONSOL Energy Inc. (collectively, the "Company") and _________________________ (the "Executive").

WHEREAS, the Executive formerly was employed by the Company as ________; and

WHEREAS, the Executive and Company entered into a Change in Control Severance Agreement, dated __________ ___, 20__, (the "Severance Agreement") which provides for certain payments and benefits in the event that the Executive's employment is terminated on account of a reason set forth in the Severance Agreement; and

WHEREAS, the Executive’s employment with the Company was terminated for reasons that qualify the Executive to receive certain payments and benefits, as set forth in Section 2(b) [or 2(e)] of the Severance Agreement, subject to, among other things, the Executive’s execution of this Agreement.

NOW, THEREFORE, for and in consideration of the Company’s commitments in Section 2(b) [or 2(e)] of the Severance Agreement, the Executive and the Company hereby agree as follows:

1.    (a)    The Executive does hereby REMISE, RELEASE AND FOREVER DISCHARGE the Company, its affiliates, subsidiaries and parents, and its and their respective officers, directors, employees, and agents, and its and their respective successors and assigns, heirs, executors, and administrators, as well as the current and former fiduciaries of any pension, welfare, or other benefit plans applicable to the employees or former employees of the Company, and the current and former welfare and other benefit plans sponsored by the Company (collectively, "Releasees") from all causes of action, suits, debts, claims and demands whatsoever in law or in equity, which the Executive ever had, now has, or hereafter may have, whether known or unknown, or which the Executive's heirs, executors, or administrators may have, by reason of any matter, cause or thing whatsoever, from the beginning of time to the date the Executive signs this Agreement, and particularly, but without limitation of the foregoing general terms, any claims arising from or relating in any way to the Executive's employment relationship with the Company, the terms and conditions of that employment relationship, and the termination of that employment relationship, including, but not limited to, any claims arising under the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act, Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act, the Worker Readjustment and Retraining Notification Act, the Consolidated Omnibus Budget Reconciliation Act, the Employee Retirement Income Security Act of 1974, the Pennsylvania Human Relations Act, and any other claims under any federal, state or local common law, statutory, or regulatory provision, now or hereafter recognized, and any claims for attorneys' fees and costs. This Agreement is effective without regard to the legal nature of the claims raised and without regard to whether any such claims are based upon tort, equity, implied or express contract or discrimination of any sort.

(b)    Although Paragraph 1(a) is intended to be a general release, it is understood and agreed that Paragraph 1(a) excludes claims related to the Executive’s right to receive the payments and benefits described in Section 2(b) [and 2(e)] of the Severance Agreement, as well as claims under any statute or common law that the Executive is legally barred from releasing, such as the Executive’s entitlement to vested pension benefits.

(c)    Nothing herein is intended to or shall preclude the Executive from filing a charge with any appropriate federal, state or local government agency and/or cooperating with said agency in its investigation. The Executive, however, explicitly waives any right to file a personal lawsuit or receive monetary damages that the agency may recover against the Releasees, without regard as to who brought any said complaint or charge. Employee further agrees that to the extent any relief, including monetary relief, is awarded in any such proceeding, all amounts paid as consideration under Section 2(b) [and 2(e)] of the Separation Agreement shall be a setoff and credit against any such award to the fullest extent permitted by law.

(d)    The Executive represents and agrees by signing below that the Executive has not been denied any leave or benefit requested, has received the appropriate pay for all hours worked for the Company, and has no known workplace injuries or occupational diseases.

(e)    To the fullest extent permitted by law, the Executive represents and affirms that (i) [other than _________________________,] the Executive has not filed or caused to be filed on the Executive's behalf any claim for relief against any Releasee and, to the best of the Executive's knowledge and belief, no outstanding claims for relief have been filed or asserted against the Company or any Releasee on the Executive's behalf; and (ii) [other than _________________________,] the Executive has not reported any improper, unethical or illegal conduct or activities to any supervisor, manager, department head, human resources representative, agent or other representative of the Company, to any member of the Company's legal or compliance departments, or to the ethics hotline, and has no knowledge of any such improper, unethical or illegal conduct or activities. The Executive agrees to promptly dismiss with prejudice all claims for relief filed before the date the Executive signs this Agreement.

2.    The Company, for and in consideration of the commitments of the Executive as set forth in this Agreement, and intending to be legally bound, does hereby REMISE, RELEASE AND FOREVER DISCHARGE the Executive from all claims, demands or causes of action arising out of facts or occurrences prior to the date of this Agreement, but only to the extent the Company knows or reasonably should know of such facts or occurrence and only to the extent such claim, demand or cause of action relates to a violation of applicable law or the performance of the Executive's duties with the Company; provided, however, that this release of claims shall not in any case be effective with respect to any claim by the Company alleging a breach of the Executive's obligations under this Agreement. [Note: The Company and the Executive may, but shall not be required to mutually agree on a case-by-case basis at the time of the signing of this release to include the foregoing provision, or a substantially similar provision, to this Agreement.]

3.    The Executive further agrees and recognizes that the Executive's employment relationship with the Company has been permanently severed, that the Executive shall not seek employment with the Company or any affiliated entity at any time in the future, and that the Company has no obligation to employ the Executive in the future.

4.    The Executive further agrees that the Executive will not disparage or subvert the Company, or make any statement reflecting negatively on the Releasees including, but not limited to, statements relating to the operation or management of the Company, the Executive's employment and the termination of the Executive's employment, irrespective of the truthfulness or falsity of such statement.

5.    The Executive acknowledges that if the Executive had not executed this Agreement containing a release of all claims, the Executive would not have been entitled to the payments and benefits set forth in Section 2(b) [or 2(e)] of the Severance Agreement.

6.    This Agreement contains the entire agreement between the Company and the Executive relating to the subject matter hereof. No prior or contemporaneous oral or written agreements or representations may be offered to alter the terms of this Agreement. To the extent Employee has entered into other agreements with the Company that are not in conflict with this Agreement, including, but not limited to the Severance Agreement, the terms of this Agreement shall not supersede, but shall be in addition to such other agreements.

7.    The Executive agrees not to disclose the terms of this Agreement or the Severance Agreement to anyone, except the Executive's spouse, attorney and, as necessary, tax/financial advisor. Likewise, the Company agrees that the terms of this Agreement will not be disclosed except as may be necessary to obtain approval or authorization to fulfill its obligations hereunder or as required by law. It is expressly understood that any violation of the confidentiality obligation imposed hereunder constitutes a material breach of this Agreement.

8.    The Executive represents that the Executive has returned to the Company and does not presently have in the Executive's possession or control any records and business documents, whether on computer or hard copy, and other materials (including but not limited to computer disks and tapes, computer programs and software, office keys, correspondence, files, customer lists, technical information, customer information, pricing information, business strategies and plans, sales records and all copies thereof) (collectively, the "Corporate Records") provided by the Company and/or its predecessors, subsidiaries or affiliates or obtained as a result of the Executive's prior employment with the Company and/or its predecessors, subsidiaries or affiliates, or created by the Executive while employed by or rendering services to the Company and/or its predecessors, subsidiaries or affiliates. In addition, the Executive has or will promptly return in good condition any other Company owned equipment or property, including, but not limited to, automobiles, personal data assistants, facsimile machines, copy machines, pagers, credit cards, cellular telephone equipment, business cards, laptops and computers. At the Executive’s request, the Company will make reasonable arrangements to transfer cellular phone numbers and personal fax numbers to the Executive.

9.    Nothing in this Agreement shall prohibit or restrict the Executive from: (i) making any disclosure of information required by law; (ii) providing information to, or testifying or otherwise assisting in any investigation or proceeding brought by, any federal regulatory or law enforcement agency or legislative body, any self-regulatory organization, or the Company's designated legal, compliance or human resources officers; or (iii) filing, testifying, participating in or otherwise assisting in a proceeding relating to an alleged violation of any federal, state or municipal law relating to fraud, or any rule or regulation of the Securities and Exchange Commission or any self-regulatory organization.

10.    The parties agree and acknowledge that the agreement by the Company described herein, and the release of any asserted or unasserted claims against the Releasees, are not and shall not be construed to be an admission of any violation of any federal, state or local statute or regulation, or of any duty owed by any of the Releasees to the Executive.

11.    The Executive agrees and recognizes that should the Executive breach any of the obligations or covenants set forth in Section 10 of the Severance Agreement, the Company will have no further obligation to provide the Executive with the consideration set in Section 2(b) [or 2(e)] of the Severance Agreement, and will have the right to seek repayment of all consideration paid up to the time of any such breach. Notwithstanding the foregoing, the Executive acknowledges that if the Executive breaches Section 10 of the Severance Agreement, and if the Company’s terminates or recovers any of the payments or benefits provided under Section 2(b) [or 2(e)] of the Severance Agreement (as provided for in Section 10 of the Severance Agreement), the release provided by Section 1 of this Agreement shall remain valid and enforceable.

12.    The Executive further agrees that the Company shall be entitled to preliminary and permanent injunctive relief, without the necessity of proving actual damages, as well as to an equitable accounting of all earnings, profits and other benefits arising from any violations of this Agreement, which rights shall be cumulative and in addition to any other rights or remedies to which the Company may be entitled.

13.    This Agreement and the obligations of the parties hereunder shall be construed, interpreted and enforced in accordance with the laws of the Commonwealth of Pennsylvania.

14.    The Executive certifies and acknowledges as follows:

(a)    That the Executive has read the terms of this Agreement, and that the Executive understands its terms and effects, including the fact that the Executive has agreed to RELEASE AND FOREVER DISCHARGE the Releasees from any legal action arising out of the Executive's employment relationship with the Company and the termination of that employment relationship; and

(b)    That the Executive has signed this Agreement voluntarily and knowingly in exchange for the consideration described herein, which the Executive acknowledges is adequate and satisfactory to the Executive and which the Executive acknowledges is in addition to any other benefits to which the Executive is otherwise entitled; and

(c)    That the Executive has been and is hereby advised in writing to consult with an attorney prior to signing this Agreement; and

(d)    That the Executive does not waive rights or claims that may arise after the date this Agreement is executed; and

TERMS AND CONDITIONS

The restricted stock units under the Company’s Equity Incentive Plan ("Plan") will entitle you to receive shares of the Company’s common stock in a series of installments over your period of continued employment with the Company and its Affiliates. Each unit represents the right to receive one share of common stock following the vesting date of that unit. Unlike a typical stock option program, the shares will be issued to you, without any cash payment required from you. However, you must pay the applicable income and employment withholding taxes (described below) when due.

The terms and provisions of your award are subject to the provisions of the Plan. A copy of the Plan is available upon request from Human Resources or on the Company's intranet site.

Other important features of your award may be summarized as follows:

Acceleration of Vesting Events: All of the shares subject to your award will vest (i.e., will not be subject to forfeiture) upon the occurrence of any of the following events, and (except as otherwise specified below and subject to the terms of your deferral election form, if applicable) such vested shares will be delivered to you on such date (or as soon as administratively practical thereafter but in no event later than 15th day of third month following such date):

-    your Separation from Service with the Company and its Affiliates due to Incapacity Retirement as defined under the Company’s Employment Retirement Plan, as in effect at that time (provided that in such event, the delivery of your vested shares will continue to be paid on the date on which those shares would normally have vested);

-    your Separation from Service with the Company and its Affiliates by reason of your death or as part of a reduction in force as specified and implemented by the Company;

-    your Separation from Service with the Company and its Affiliates by action taken by the Company (including any Affiliate) without Cause (as such term is defined in the Plan) and after a decision by the Company’s Chief Executive Officer, in his or her sole and absolute discretion, that such Separation from Service without Cause qualifies for special vesting treatment hereunder; or

-    completion of a Change in Control (as such term is defined in the Plan).

Notwithstanding the foregoing, in no event will any special vesting of your shares occur should your employment with the Company and its Affiliates be terminated for Cause or should you leave the Company’s and its Affiliates’ employ for any reason other than in connection with one of the accelerated vesting events specified above.

Notwithstanding the foregoing or any provision contained herein to the contrary, the delivery of any vested shares shall be delayed until six (6) months after your Separation from Service to the extent required by Section 409A(a)(2)(B)(i) of the Code as provided under the terms of the Plan.

Forfeitability: Should you cease employment with the Company and its Affiliates (including by virtue of an Affiliate ceasing to be an Affiliate of the Company) under circumstances which do not otherwise entitle you to accelerated vesting of the unvested shares subject to your award, then your award will be cancelled with respect to those unvested shares, and the number of your restricted stock units will be reduced accordingly. You will thereupon cease to have any right or entitlement to receive any shares of common stock under those cancelled units.

Should your employment be terminated for "Cause" (as defined in the Plan) or should you breach any of the non-competition or proprietary information covenants set forth in the Covenants section below, then not only will your award be cancelled with respect to any unvested shares at the time subject to your award, but you will also forfeit all of your right, title and interest in and to any shares which have vested under your award and which are either held by you at that time or are otherwise subject to deferred issuance. The certificates for any vested shares you hold at the time of such termination or breach must be promptly returned to the Company, and the Company will in addition impose an immediate stop transfer order with respect to those certificates. Accordingly, upon such termination of your employment or breach of any of your non-competition or proprietary information covenants below, you will cease to have any further right or entitlement to receive or retain the shares of common stock subject to your forfeited award. In addition, to the extent you have sold any of your vested shares within the six (6)-month period ending with the date of your termination for Cause or your breach of any covenant set forth in the Covenants section below or at any time thereafter, then you will be required to repay to the Company, within ten (10) days after receipt of written demand from the Company, the cash proceeds you received upon each such sale, provided such demand is made by the Company within one year after the date of that sale.

Transferability: The shares issued to you following the vesting of your award will be registered under the federal securities laws. Sales of those shares will be subject to any market black-out periods the Company may impose from time to time and must be made in compliance with the Company’s insider trading policies and applicable securities laws.

Prior to your actual receipt of the shares in which you vest under your award, you may not transfer any interest in your award or the underlying shares or pledge or otherwise hedge the sale of those shares, including (without limitation) any short sale, put or call option or any other instrument tied to the value of those shares. However, your right to receive any shares which have vested under your restricted stock units but which remain unissued at the time of your death may be transferred pursuant to the provisions of your will or the laws of inheritance following your death.

[Holding Requirement: You are required to hold, and not sell, transfer or otherwise dispose of, fifty percent (50%) of the shares issued to you following the vesting of your award (after accounting for the payment of any related taxes in connection with the vesting of the award) until the earlier of (i) ten (10) years from the Award Date; or (ii) your attainment of age sixty-two (62).]

Federal Income Taxation: You will recognize ordinary income for federal income tax purposes on the date the shares which vest under your award are actually issued to you, and you must satisfy your income tax withholding obligation applicable to that income. The amount of your taxable income will be equal to the closing selling price per share of the Company’s common stock on the New York Stock Exchange on the issue date times the number of shares issued to you on that date.

FICA Taxes:      You will be liable for the payment of the employee share of the FICA (Social Security and Medicare) taxes applicable to the shares subject to your award at the time those shares vest, and not at the time they are subsequently issued. No additional FICA taxes will be due when the shares are actually issued. FICA taxes will be based on the closing selling price of the shares on the New York Stock Exchange on the date those shares vest under the award.

Withholding Taxes: You must pay all applicable federal and state income and employment withholding taxes when due.  The Company will automatically withhold from the total number of Shares deliverable to you upon the applicable vesting date, the number of Shares having a Fair Market Value equal to the minimum statutory tax withholding requirements (or as otherwise approved by the Company) as determined in accordance with the Plan.  In the event of any remaining tax balance, you will be required to deliver a check for that amount payable to CONSOL Energy Inc. before the Shares are deposited into your Smith Barney account.

Stockholder Rights: You will not have any stockholder rights, including voting rights and actual dividend rights, with respect to the shares subject to your award until you become the record holder of those shares following their actual issuance to you and your satisfaction of the applicable withholding taxes.

Dividend Equivalent Rights: Should a regular cash dividend be declared on the Company’s common stock at a time when unissued shares of such common stock are subject to your award, then the number of shares at that time subject to your award will automatically be increased by an amount determined in accordance with the following formula, rounded down to the nearest whole share:

X = (A x B)/C, where

X    =    the additional number of shares which will become subject             to your award by reason of the cash dividend;    

A    =    the number of unissued shares subject to this award as of             the record date for such dividend;

B    =    the per share amount of the cash dividend; and

C    =    the closing selling price per share of the Company’s                 common stock on the New York Stock Exchange on the                 payment date of such dividend.

The additional shares resulting from such calculation will be subject to the same terms and conditions (including, without limitation, any applicable vesting requirements, forfeiture provisions and deferral election) as the unissued shares of common stock to which they relate under the award.

Other Adjustments: In the event of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other similar change affecting the Company’s outstanding common stock as a class without the Company’s receipt of consideration, the number and/or class of securities subject to your award will be appropriately adjusted to preclude any dilution or enlargement of your rights under the award.

Covenants: As a further condition to your right and entitlement to receive the shares of the Company’s common stock subject to your award, you hereby agree to abide by the terms and conditions of the following non-competition and proprietary information covenants:

Non-Competition Covenant.

You hereby acknowledge and recognize the highly competitive nature of the business of the Company and its Affiliates and accordingly agree that during the term of your employment and for a period of [two (2) years][one (1) year][six (6) months] immediately thereafter:

(a)    You will not directly or indirectly engage in any business which is in competition with any line of business conducted by the Company or any of its Affiliates, including (without limitation) any engagement as an officer, director, proprietor, employee, partner, investor (other than as a holder of less than 1% of the outstanding capital stock of a publicly traded corporation), consultant, advisor, agent or sales representative, in any geographic region in which the Company or any of its Affiliates conduct any such competing line of business.

(b)    You will not perform (or otherwise solicit the performance of) services for any customer or client of the Company of any of its Affiliates.

(c)    You will not directly or indirectly induce any employee of the Company or any of its Affiliates to (i) engage in any activity or conduct which is prohibited pursuant to this non-competition covenant or (ii) terminate such individual’s employment with the Company or any of its Affiliates. Moreover, you will not directly or indirectly employ or offer employment (in connection with any business which is in competition with any line of business conducted by the Company or any of its Affiliates) to any person who was employed by the Company or any of its Affiliates unless such person shall have ceased to be employed by the Company or any of its Affiliates for a period of at least 12 months.

(d)    You will not directly or indirectly assist others in engaging in any of the activities which are prohibited under subparagraphs (a) through (c) above.

It is expressly understood and agreed that although you and the Company consider the foregoing restrictions to be reasonable, should a final judicial determination be made by a court of competent jurisdiction that the time or territory or any other restriction contained in this agreement is an unenforceable restriction against you, the provision of this agreement will not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable. Alternatively, should any court of competent jurisdiction find that any restriction contained in this agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding shall not affect the enforceability of any of the other restrictions contained herein.

Proprietary Information Covenant.

You and the Company agree that certain materials, including (without limitation) information, data and other materials relating to customers, development programs, costs, marketing, trading, investment, sales activities, promotion, credit and financial data, manufacturing processes, financing methods, plans or the business and affairs of the Company and its Affiliates, constitute proprietary confidential information and trade secrets. Accordingly, you will not at any time during or after your employment with the Company and its Affiliates disclose or use for your own benefit or purposes or the benefit or purposes of any other person, firm, partnership, joint venture, association, corporation or other business organization, entity or enterprise other than the Company and any of its Affiliates, any proprietary confidential information or trade secrets, provided that the foregoing shall not apply to information which is not unique to the Company or any of its Affiliates or which is generally known to the industry or the public other than as a result of your breach of this covenant. You agree that upon termination of your employment with the Company and its Affiliates for any reason, you will immediately return to the Company all memoranda, books, papers, plans, information, letters and other data, and all copies thereof or therefrom, which in any way relate to the business of the Company and its Affiliates. You further agree that you will not retain or use for your own account at any time any trade names, trademark or other proprietary business designation used or owned in connection with the business of the Company or any of its Affiliates.

Notwithstanding anything contained herein to the contrary, this Agreement shall not prohibit disclosure of proprietary confidential information if (i) it is required by law or by a court of competent jurisdiction or (ii) it is in connection with any judicial, arbitration, dispute resolution or other legal proceeding in which your legal rights and obligations as an employee or under this Agreement are at issue; provided, however, that you shall, to the extent practicable and lawful in any such event, give prior notice to the Company of your intent to disclose proprietary confidential information so as to allow the Company an opportunity (which you shall not oppose) to obtain such protective orders or similar relief with respect thereto as may be deemed appropriate.

Notwithstanding the foregoing, nothing in this Agreement restricts or prohibits you from reporting possible violations of law or regulation to any governmental agency or entity, including but not limited, to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or from making other disclosures that are protected under state or federal law or regulation. You do not need the prior authorization of the Company to make such reports or disclosures.  You are not required to notify the Company that you have made any such reports or disclosures.

Failure to Enforce Not A Waiver: The failure of the Company to enforce at any time any provision of this Agreement shall in no way be construed to be a waiver of such provision or of any other provision hereof.

Legends: The Company may at any time place legends referencing the provisions of this Agreement, and any applicable federal or state securities law restrictions on all certificates, if any, representing the shares relating to this award.

Governing Law: This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to the conflicts of laws provisions thereof.

Amendments: This Agreement may be amended or modified at any time by an instrument in writing signed by the parties hereto, or as otherwise provided under the Plan. Notwithstanding, the Companymay, in its sole discretion and without your consent, modify or amend the terms and conditions of this award, impose conditions on the timing and effectiveness of the issuance of the shares, or take any other action it deems necessary or advisable, to cause this award to comply with Section 409A of the Code (or an exception thereto).

Section 409A:This Award is intended to comply with Section 409A of the Code (or an exception thereto) and the regulations promulgated thereunder and shall be construed accordingly. Notwithstanding, you recognize and acknowledge that Section 409A of the Code may impose upon you certain taxes or interest charges for which you are and shall remain solely responsible.

Notices: Any notice, request, instruction or other document given under this Agreement shall be in writing and shall be addressed and delivered, in the case of the Company, to the Corporate Secretary of the Company at the principal office of the Company and, in your case, to your address as shown in the records of the Company and its Affiliates or to such other address as may be designated in writing by either party.

Award Subject to Plan: This Award is subject to the Plan. The terms and provisions of the Plan as it may be amended from time to time are hereby incorporated herein by reference.

Entire Agreement: Except as otherwise provided in this Agreement, this Agreement and the Plan are: (i) intended to be the final, complete, and exclusive statement of the terms of the agreement between you and the Company with regard to the subject matter of this Agreement; (ii) supersede all other prior agreements, communications, and statements, whether written or oral, express or implied, pertaining to that subject matter; and (iii) may not be contradicted by evidence of any prior or contemporaneous statements or agreements, oral or written, and may not be explained or supplemented by evidence of consistent additional terms.

Attached hereto is a special supplement to such prospectus which provides certain other relevant information concerning your award. Please review both the updated plan prospectus and the supplement carefully so that you fully understand your rights and benefits under your award and the limitations, restrictions and vesting provisions applicable to the award.

Employment at Will: Nothing in the program will provide you with any right to continue in the Company’s and its Affiliates’ employ for any period of specific duration or interfere with or otherwise restrict in any way your rights or the rights of the Company and its Affiliates to terminate your service at any time for any reason, with or without cause. Your employee status with the Company and its Affiliates will accordingly remain at will.

[Clawback: Notwithstanding any provisions in this Agreement to the contrary, any compensation, payments, or benefits provided hereunder (or profits realized from the sale of Shares delivered hereunder), whether in the form of cash or otherwise, shall be subject to recoupment and recapture to the extent necessary to comply with the requirements of any Company-adopted policy and/or laws or regulations, including, but not limited to, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the Exchange Act, Section 304 of the Sarbanes Oxley Act of 2002, the New York Stock Exchange Listed Company Manual or any rules or regulations promulgated thereunder with respect to such laws, regulations and/or securities exchange listing requirements, as may be in effect from time to time, and which may operate to create additional rights for the Company with respect to this grant and recovery of amounts relating thereto.  By accepting this Award, you agree and acknowledge that you are obligated to cooperate with, and provide any and all assistance necessary to, the Company to recover, recoup or recapture this Award or amounts paid under the Plan pursuant to such law, government regulation, stock exchange listing requirement or Company policy. Such cooperation and assistance shall include, but is not limited to, executing, completing and submitting any documentation necessary to recover, recoup or recapture this Award or amounts paid under the Plan from a Participant’s accounts, or pending or future compensation or other grants.]

SUMMARY PLAN DESCRIPTION FOR

EQUITY INCENTIVE PLAN

EX-10.80

CONSOL ENERGY INC.

EQUITY INCENTIVE PLAN

PERFORMANCE SHARE UNIT AWARD AGREEMENT

This Performance Share Unit Award Agreement set forth below (this “Agreement”) is dated as of the grant date (the “Grant Date”) set forth on Exhibit A and is between CONSOL Energy Inc., a Delaware corporation (the “Company”), and the individual to whom the Compensation Committee of the Board of Directors (the “Committee”) of the Company has made this Performance Award and whose name is set forth on Exhibit A (the “Participant”).

The Company has established the CONSOL Energy Inc. Equity Incentive Plan, as amended (the “Plan”), to advance the interests of the Company and its stockholders by providing incentives to certain eligible persons who contribute significantly to the strategic and long-term performance objectives and growth of the Company. Unless the context otherwise requires, all capitalized terms not otherwise defined in this Agreement have the same meaning given such capitalized terms in the Plan.

Pursuant to the provisions of the Plan, the Committee has full power and authority to direct the execution and delivery of this Agreement in the name and on behalf of the Company, and has authorized the execution and delivery of this Agreement.

Agreement

1.Performance Share Unit Award. Subject to and pursuant to all terms and conditions stated in this Agreement and in the Plan, as of the Grant Date, the Company hereby grants a Performance Award to the Participant in the form of performance share units (the “Performance Share Units”) with the target number set forth on Exhibit A. Each Performance Share Unit awarded under this Agreement shall represent a contingent right to receive one share of the Company’s common stock as described more fully herein, to the extent such Performance Share Unit is earned and becomes payable pursuant to the terms of this Agreement. Notwithstanding, Performance Share Units as initially awarded have no independent economic value, but rather are mere units of measurement used for purposes of calculating the value of benefits, if any, to be paid under this Agreement.

2.Performance Period. The “Performance Period” means the performance period as set forth on Exhibit A.

3.Performance Goals of the Performance Share Units. Subject to the provisions of this Agreement, the total number of Performance Share Units awarded to Participant will be earned (at a maximum award level of 200% of the target number of Performance Share Units awarded), if the performance measures set by and on file with the Committee are satisfied (each, a “Performance Goal”); provided, however, that the Committee has sole discretion to determine whether the Performance Goals, as defined, are met and the date of such determination shall be the vesting date of the Award (the “Vesting Date”) and provided, further, that the Award will only become payable, except as otherwise provided herein, if the Participant remains an employee of the Company and its subsidiaries through the Vesting Date. As a condition to receiving this Award, Participant agrees that all determinations made by the Committee are final and conclusive.

4.Issuance and Distribution.

4.1After the end of the Performance Period and prior to the commencement of the payment of Shares relating to the Award, the Committee shall certify in writing the extent to which the Performance Goals and any other material terms of this Agreement have been achieved. For purposes of this provision, and for so long as the Code permits, the approved minutes of the Committee meeting in which the certification is made may be treated as written certification.

4.2Subject to the terms and conditions of this Agreement, Performance Share Units earned by the Participant will be settled and paid in shares of the Company’s common stock in the first calendar year immediately following the end of the Performance Period on a date determined in the Committee’s discretion, but in no event later than March 15th of such year, subject to Participant’s satisfaction of all applicable income and employment withholding taxes (the “Payment Date”).

4.3Notwithstanding any other provision of this Agreement, in the event of a Change in Control, as defined in Section 16 of the Plan, the Performance Goals will be deemed to have been achieved on such date and the Performance Share Units shall be paid based on performance relative to the Performance Goals as of such date, and the value of such units will be settled on the closing date of the Change in Control transaction (the “CiC Payment Date”); provided, further, in the event of a Change in Control, Performance Share Units may, in the Committee’s discretion,be settled in cash and/or securities or other property.

4.4The Participant is required to hold, and not sell, transfer or otherwise dispose of fifty percent (50%) of the shares issued to the Participant following the vesting of the Performance Share Units (after accounting for the payment of any related taxes in connection with the vesting of the Performance Share Units) until the earlier of (i) ten (10) years from the Grant Date; or (ii) the Participant’s attainment of age sixty-two (62). [Note: Does not apply to Grades 14 or below]

5.Dividends. Each Performance Share Unit will be cumulatively credited with dividends that are paid on the Company’s common stock in the form of additional units. These additional units shall be deemed to have been purchased on the record date for the dividend using the closing stock price of the Company’s common stock as reported in The Wall Street Journal and shall be subject to all the same conditions and restrictions as provided in this Agreement applicable to Performance Share Units.

6.Change in Participant’s Status. In the event the Participant Separates from Service (i) on or after the date the Participant has reached the age of 62, (ii) on account of death or Disability, or (iii) by action taken by the Company (including any Affiliate) without Cause and after a decision by the Company’s Chief Executive Officer, in his or her sole and absolute discretion, that such Separation from Service without Cause qualifies for special vesting treatment hereunder (a “Qualifying Separation from Service without Cause”), prior to any Payment Date or the CiC Payment Date, as applicable, the Participant shall be entitled to retain the Performance Share Units and receive payment therefore to the extent earned and payable pursuant to the provisions of this Agreement; provided, however, that in the case of a Separation from Service on or after the Participant has reached the age of 62 or on account of Disability, the Participant shall only be entitled to retain a prorated portion of the Performance Share Units determined at the end of the Performance Period and based on the ratio of the number of complete months the Participant is employed or serves during the Performance Period to the total number of months in the Performance Period. In the event the Participant Separates from Service for any other reason, including, but not limited to, by the Participant voluntarily, or by the Company (including any Affiliate) with Cause or without Cause (other than in connection with a Qualifying Separation of Service without Cause), prior to any Payment Date or the CiC Payment Date, as applicable, the Performance Share Units awarded to the Participant shall be cancelled and forfeited, whether payable or not, without payment by the Company or any Affiliate. Any payments due a deceased Participant shall be paid to his or her estate as provided herein after the end of the Performance Period.

7.Tax Consequences/Withholding.

7.1It is intended that: (i) the Participant’s Performance Share Units shall be considered to be subject to a substantial risk of forfeiture in accordance with those terms as defined in Sections 409A and 3121(v)(2) of the Code; and (ii) the Participant shall have merely an unfunded, unsecured promise to be paid a benefit, and such unfunded promise shall not consist of a transfer of “property” within the meaning of Code Section 83.

7.2Participant acknowledges that any income for federal, state or local income tax purposes, including payroll taxes, that the Participant is required to recognize on account of the vesting of the Performance Share Units and/or issuance of the Shares under this Award to Participant shall be subject to withholding of tax by the Company. In accordance with administrative procedures established by the Company, Participant may elect to satisfy Participant’s minimum statutory withholding tax obligations, if any, on account of the vesting of the Performance Share Units and/or issuance of Shares under this Award, in one or a combination of the following methods: in cash or by separate check made payable to the Company and/or by authorizing the Company to withhold from the Shares to be issued to the Participant a sufficient number of whole Shares distributable in connection with this Award equal to the applicable minimum statutory withholding tax obligation or as otherwise approved by the Committee.

7.3This Agreement is intended to comply with, or be excepted from coverage under, Section 409A of the Code and the regulations promulgated thereunder and shall be administered, interpreted and construed accordingly. Notwithstanding any provision of this Agreement to the contrary, if any benefit provided under this Agreement is subject to the provisions of Section 409A of the Code and the regulations issued thereunder (and not excepted therefrom), the provisions of the Agreement shall be administered, interpreted and construed in a manner necessary to comply with Section 409A (or disregarded to the extent such provision cannot be so administered, interpreted, or construed). Notwithstanding, Section 409A may impose upon the Participant certain taxes or other charges for which the Participant is and shall remain solely responsible, and nothing contained in this Agreement or the Plan shall be construed to obligate any member of the Committee or Board, the Company or any Affiliate (or its employees, officers or directors) for any such taxes or other charges.

7.4Notwithstanding any provision of this Agreement to the contrary, if the Award of Performance Share Units under this Agreement is intended to qualify as performance-based compensation under Section 162(m) of the Code and the regulations issued thereunder and a provision of this Agreement would prevent such Award from so qualifying, such provision shall be administered, interpreted and construed to carry out such intention (or disregarded to the extent such provision cannot be so administered, interpreted or construed).

8.Non-Competition.

8.1The Participant hereby agrees that this Section 8 is reasonable and necessary in order to protect the legitimate business interests and goodwill of the Company, including the Company’s trade secrets, valuable confidential business and professional information, substantial relationships with prospective and existing customers and clients, and specialized training provided to the Participant and other employees of the Company. The Participant acknowledges and recognizes the highly competitive nature of the business of the Company and its Affiliates and accordingly agrees that during the term of Participant’s employment and for a period of [two (2) years][one (1) year][six (6) months] after the termination thereof:

(a)The Participant will not directly or indirectly engage in any business substantially similar to any line of business conducted by the Company or any of its Affiliates, including, but not limited to, where such engagement is as an officer, director, proprietor, employee, partner, investor (other than as a holder of less than 1% of the outstanding capital stock of a publicly traded corporation), consultant, advisor, agent or sales representative, in any geographic region in which the Company or any of its Affiliates conducted business;

(b)The Participant will not contact, solicit, perform services for, or accept business from any customer or prospective customer of the Company or any of its Affiliates;

(c)The Participant will not directly or indirectly induce any employee of the Company or any of its Affiliates to: (1) engage in any activity or conduct which is prohibited pursuant to subparagraph 8.1(a); or (2) terminate such employee’s employment with the Company or any of its Affiliates. Moreover, the Participant will not directly or indirectly employ or offer employment (in connection with any business substantially similar to any line of business conducted by the Company or any of its Affiliates) to any person who was employed by the Company or any of its Affiliates unless such person shall have ceased to be employed by the Company or any of its Affiliates for a period of at least 12 months; and

(d)The Participant will not directly or indirectly assist others in engaging in any of the activities, which are prohibited under subparagraphs (a) — (c) above.

8.2It is expressly understood and agreed that although the Participant and the Company consider the restrictions contained in this Section 8 to be reasonable, if a final judicial determination is made by a court of competent jurisdiction that the time or territory or any other restriction contained in this Agreement is an unenforceable restriction against the Participant, the provisions of this Agreement shall not be rendered void but shall be deemed amended to apply as to such maximum time and territory and to such maximum extent as such court may judicially determine or indicate to be enforceable against such Participant. Alternatively, if any court of competent jurisdiction finds that any restriction contained in this Agreement is unenforceable, and such restriction cannot be amended so as to make it enforceable, such finding shall not affect the enforceability of any of the other restrictions contained herein. The restrictive covenants set forth in this Section 8 shall be extended by any amount of time that the Participant is in breach of such covenants, such that the Company receives the full benefit of the time duration set forth above.

9.Confidential Information and Trade Secrets. The Participant and the Company agree that certain materials, including, but not limited to, information, data and other materials relating to customers, development programs, costs, marketing, trading, investment, sales activities, promotion, credit and financial data, manufacturing processes, financing methods, plans or the business and affairs of the Company and its Affiliates, constitute proprietary confidential information and trade secrets. Accordingly, the Participant will not at any time during or after the Participant’s employment with the Company (including any Affiliate) disclose or use for such Participant’s own benefit or purposes or the benefit or purposes of any other person, firm, partnership, joint venture, association, corporation or other business organization, entity or enterprise other than the Company and any of its Affiliates, any proprietary confidential information or trade secrets, provided that the foregoing shall not apply to information which is not unique to the Company or any of its Affiliates or which is generally known to the industry or the public other than as a result of such Participant’s breach of this covenant. The Participant agrees that upon termination of employment with the Company (including any Affiliate) for any reason, the Participant will immediately return to the Company all memoranda, books, papers, plans, information, letters and other data, and all copies thereof or therefrom, which in any way relate to the business of the Company and its Affiliates, except that the Participant may retain personal notes, notebooks and diaries. The Participant further agrees that the Participant will not retain or use for the Participant’s own account at any time any trade names, trademark or other proprietary business designation used or owned in connection with the business of the Company or any of its Affiliates.

Notwithstanding the foregoing, nothing in this Agreement restricts or prohibits the Participant from reporting possible violations of law or regulation to any governmental agency or entity, including but not limited, to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or from making other disclosures that are protected under state or federal law or regulation.  The Participant does not need the prior authorization of the Company to make such reports or disclosures.  The Participant is not required to notify the Company that he or she has made any such reports or disclosures.

10.Remedies/Forfeiture.

10.1The Participant acknowledges that a violation or attempted violation on the Participant’s part of Sections 8 and/or 9 will cause irreparable damage to the Company and its Affiliates, and the Participant therefore agrees that the Company and its Affiliates shall be entitled as a matter of right to an injunction, out of any court of competent jurisdiction, restraining any violation or further violation of such promises by the Participant or the Participant’s employees, partners or agents. The Participant agrees that such right to an injunction is cumulative, in addition to whatever other remedies the Company (including any Affiliate) may have under law or equity and to the Participant’s obligations to make timely payment to the Company as set forth in Section 10.2 of this Agreement. The Participant further acknowledges and agrees that the Participant’s Performance Share Units shall be cancelled and forfeited without payment by the Company if the Participant breaches any of his obligations set forth in Sections 8 and 9 herein.

10.2At any point after becoming aware of a breach of any obligation set forth in Sections 8 and 9 of this Agreement, the Company shall provide notice of such breach to the Participant. By agreeing to receive the Performance Share Units pursuant to this Agreement, the Participant agrees that within ten (10) days after the date the Company provides such notice, the Participant shall pay to the Company in cash an amount equal to any and all distributions paid to or on behalf of such Participant under this Agreement within the six (6) months prior to the date of the earliest breach. The Participant agrees that failure to make such timely payment to the Company constitutes an independent and material breach of the terms and conditions of this Agreement, for which the Company may seek recovery of the unpaid amount as liquidated damages, in addition to all other rights and remedies the Company may have resulting from the Participant’s breach of the obligations set forth in Sections 8 and/or 9. The Participant agrees that timely payment to the Company as set forth in this provision of this Agreement is reasonable and necessary because the compensatory damages that will result from breaches of Sections 8 and/or 9 cannot readily be ascertained. Further, the Participant agrees that timely payment to the Company as set forth in this provision of this Agreement is not a penalty, and it does not preclude the Company from seeking all other remedies that may be available to the Company, including without limitation those set forth in this Section 10.

11.Assignment/Nonassignment.

11.1The Company shall have the right to assign this Agreement, including without limitation Sections 8 and/or 9, and the Participant agrees to remain obligated by all provisions of this Agreement that are assigned to any successor, assign or surviving entity. Any successor to the Company is an intended third party beneficiary of this Agreement.

11.2The Performance Share Units shall not be sold, pledged, assigned, hypothecated, transferred or disposed of (a “Transfer”) in any manner, other than by will or the laws of descent and distribution. Any attempt by the Participant to Transfer the Performance Share Units in violation of the terms of this Agreement shall render the Performance Share Units null and void, and result in the immediate forfeiture of such Performance Share Units, without payment by the Company.

12.Impact on Benefit Plans. Payments under this Agreement shall not be considered as earnings for purposes of the Company’s and/or Affiliate’s qualified retirement plans or any other retirement or benefit plan unless specifically provided for therein. Nothing herein shall prevent the Company or any Affiliate from maintaining additional compensation plans and arrangements for its employees.

13.Successors; Changes in Stock. The obligation of the Company under this Agreement shall be binding upon the successors and assigns of the Company. If a dividend or other distribution shall be declared upon the Company’s common stock payable in Shares, the Performance Share Units and the Shares on which the Performance Goals are based shall be adjusted by adding thereto the number of Shares which would have been distributable thereon if such shares and Performance Share Units had been actual Shares and outstanding on the date fixed for determining the stockholders entitled to receive such stock dividend or distribution. In the event of any spin-off, split-off or split-up, dividend in property other than cash, recapitalization or other change in the capital structure of the Company, or any merger, consolidation, reorganization, partial or complete liquidation or other distribution of assets (other than a normal cash dividend), or any other corporate transaction or event having an effect similar to any of the foregoing, or extraordinary distribution to stockholders of the Company’s common stock, the Performance Share Units, the Shares relating to the Performance Share Units, and the Performance Goals shall be appropriately adjusted to prevent dilution or enlargement of the rights of Participants which would otherwise result from any such transaction, provided such adjustment shall be consistent with Code Section 162(m) and Section 409A, as applicable.

In the case of a Change in Control, any obligation under this Agreement shall be handled in accordance with the terms of Section 4 hereof. In any case not constituting a Change in Control in which the Company’s common stock is changed into or becomes exchangeable for a different number or kind of shares of stock or other securities of the Company or another corporation, or cash or other property, whether through reorganization, reclassification, recapitalization, stock split-up, combination of shares, merger or consolidation, then (i) the value of the Performance Share Units constituting the Award shall be calculated based on the closing price of such common stock on the closing date of the transaction on the principal market on which such common stock is traded, (ii) there shall be substituted for each Performance Share Unit constituting the Award, the number and kind of shares of stock or other securities (or cash or other property) into which each outstanding Share shall be so changed or for which each such Share shall be exchangeable, and (iii) the Share on which the Performance Goals are based shall be appropriately and equitably adjusted, provided any such adjustments shall be consistent with Code Section 162(m) and Section 409A, as applicable. In the case of any such adjustment, the Performance Share Units shall remain subject to the terms of the Agreement.

14.Governing Law, Jurisdiction, and Venue.

14.1This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to the principles of conflicts of law.

14.2The Participant hereby irrevocably submits to the personal and exclusive jurisdiction of the United States District Court for the Western District of Pennsylvania or the Court of Common Pleas of Allegheny County, Pennsylvania in any action or proceeding arising out of, or relating to, this Agreement (whether such action or proceeding arises under contract, tort, equity or otherwise). The Participant hereby irrevocably waives any objection which the Participant now or hereafter may have to the laying of venue or personal jurisdiction of any such action or proceeding brought in said courts.

14.3Jurisdiction over, and venue of, any such action or proceeding shall be exclusively vested in the United States District Court for the Western District of Pennsylvania or the Court of Common Pleas of Allegheny County, Pennsylvania.

14.4Provided that the Company commences any such action or proceeding in the courts identified in Section 14.3, the Participant irrevocably waives the Participant’s right to object to or challenge the above selected forum on the basis of inconvenience or unfairness under 28 U.S.C. § 1404, 42 Pa. C.S. § 5322 or similar state or federal statutes. The Participant agrees to reimburse the Company for all of the attorneys’ fees and costs it incurs to oppose the Participant’s efforts to challenge or object to litigation proceeding in the courts identified in Section 14.3 with respect to actions arising out of or relating to this Agreement (whether such actions arise under contract, tort, equity or otherwise).

15.Failure to Enforce Not a Waiver. The failure of the Company to enforce at any time any provision of this Agreement shall in no way be construed to be a waiver of such provision or of any other provision hereof.

16.Severability. In the event that any one or more of the provisions of this Agreement shall be held to be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

17.Funding. This Agreement is not funded and all amounts payable hereunder, if any, shall be paid from the general assets of the Company or its Affiliate, as applicable. No provision contained in this Agreement or the Plan and no action taken pursuant to the provisions of this Agreement or the Plan shall create a trust of any kind or require the Company to maintain or set aside any specific funds to pay benefits hereunder. To the extent the Participant acquires a right to receive payments from the Company under this Agreement, such right shall be no greater than the right of any unsecured general creditor of the Company.

18.Headings. The descriptive headings of the Sections of this Agreement are inserted for convenience of reference only and shall not constitute a part of this Agreement.

19.Awards Subject to Plan. In the event of a conflict between any term or provision contained herein and a term or provision of the Plan, the applicable terms and provisions of the Plan will govern and prevail.

20.Amendment or Termination of this Agreement. This Agreement may be modified, amended, suspended or terminated by the Committee at any time; provided, however, that no modification, amendment, suspension or termination of the Plan or this Agreement shall adversely affect the rights of the Participant under this Agreement without the consent of such Participant. Notwithstanding the foregoing or any provision of this Agreement to the contrary, the Company may, in its sole discretion and without the Participant’s consent, modify or amend the terms of the Agreement or a Performance Share Unit award, or take any other action it deems necessary or advisable, to cause the Agreement to comply with Section 409A or Section 162(m) (or an exception thereto). Any modification, amendment, suspension or termination shall only be effective upon a writing issued by the Company, and the Participant shall not offer evidence of any purported oral modifications or amendments to vary or contradict the terms of this Agreement document.

21.Clawback. Notwithstanding any provisions in this Agreement to the contrary, any compensation, payments, or benefits provided hereunder (or profits realized from the sale of Shares delivered hereunder), whether in the form of cash or otherwise, shall be subject to recoupment and recapture to the extent necessary to comply with the requirements of any Company-adopted policy and/or laws or regulations, including, but not limited to, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, the Exchange Act, Section 304 of the Sarbanes Oxley Act of 2002, the New York Stock Exchange Listed Company Manual or any rules or regulations promulgated thereunder with respect to such laws, regulations and/or securities exchange listing requirements, as may be in effect from time to time, and which may operate to create additional rights for the Company with respect to this grant and recovery of amounts relating thereto.  By accepting this grant of Performance Share Units, the Participant agrees and acknowledges that he or she is obligated to cooperate with, and provide any and all assistance necessary to, the Company to recover, recoup or recapture this grant of Performance Share Units or amounts paid under the Plan pursuant to such law, government regulation, stock exchange listing requirement or Company policy. Such cooperation and assistance shall include, but is not limited to, executing, completing and submitting any documentation necessary to recover, recoup or recapture this grant of Performance Share Units or amounts paid under the Plan from a Participant’s accounts, or pending or future compensation or other grants.

Exhibit 95

Mine Safety and Health Administration Safety Data

We believe that CONSOL Energy is one of the safest mining companies in the world. The Company has in place health and safety programs that include extensive employee training, accident prevention, workplace inspection, emergency response, accident investigation, regulatory compliance and program auditing. The objectives of our health and safety programs are to eliminate workplace incidents, comply with all mining-related regulations and provide support for both regulators and the industry to improve mine safety.

The operation of our mines is subject to regulation by the federal Mine Safety and Health Administration (MSHA) under the Federal Mine Safety and Health Act of 1977 (Mine Act). MSHA inspects our mines on a regular basis and issues various citations, orders and violations when it believes a violation has occurred under the Mine Act. We present information below regarding certain mining safety and health violations, orders and citations, issued by MSHA and related assessments and legal actions and mine-related fatalities with respect to our coal mining operations. In evaluating this information, consideration should be given to factors such as: (i) the number of violations, orders and citations will vary depending on the size of the coal mine, (ii) the number of violations, orders and citations issued will vary from inspector to inspector and mine to mine, and (iii) violations, orders and citations can be contested and appealed, and in that process, are often reduced in severity and amount, and are sometimes dismissed.

The table below sets forth, for the year ended December 31, 2016, for each coal mine of CONSOL Energy and its subsidiaries that has an outstanding MSHA citation, order or violation, the total number of:  (i) violations of mandatory health or safety standards that could significantly and substantially contribute to the cause and effect of a coal or other mine safety or health hazard under section 104 of the Mine Act for which the operator received a citation from MSHA; (ii) orders issued under section 104(b) of the Mine Act; (iii) citations and orders for unwarrantable failure of the mine operator to comply with mandatory health or safety standards under section 104(d) of the Mine Act; (iv) flagrant violations under section 110(b)(2) of the Mine Act; (v) imminent danger orders issued under section 107(a) of the Mine Act; (vi) proposed assessments from MHSA (regardless of whether CONSOL Energy has challenged or appealed the assessment); (vii) mining-related fatalities; (viii) notices from MSHA of a pattern of violations of mandatory health or safety standards that are of such nature as could have significantly and substantially contributed to the cause and effect of coal or other mine health or safety hazards under section 104(e) of the Mine Act; (ix) notices from MSHA regarding the potential to have a pattern of violations as referenced in (viii) above; and (x) pending legal actions before the Federal Mine Safety and Health Review Commission (as of December 31, 2016) involving such coal or other mine, as well as the aggregate number of legal actions instituted and the aggregate number of legal actions resolved during the reporting period.

Exhibit 99.1

February 1, 2017

Mr. Jeremy Hayhurst

CONSOL Energy Inc.

1000 Consol Energy Drive

Canonsburg, Pennsylvania 15317

Dear Mr. Hayhurst:

In accordance with your request, we have audited the estimates prepared by CONSOL Energy Inc. (CONSOL), as of December 31, 2016, of the proved reserves and future revenue to the CONSOL interest in certain oil and gas properties located in the United States. It is our understanding that the proved reserves estimated herein constitute all of the proved reserves owned by CONSOL. We have examined the estimates with respect to reserves quantities, reserves categorization, future producing rates, future net revenue, and the present value of such future net revenue, using the definitions set forth in U.S. Securities and Exchange Commission (SEC) Regulation S-X Rule 4‑10(a). The estimates of reserves and future revenue have been prepared in accordance with the definitions and regulations of the SEC and, with the exception of the exclusion of future income taxes, conform to the FASB Accounting Standards Codification Topic 932, Extractive Activities-Oil and Gas. We completed our audit on or about the date of this letter. This report has been prepared for CONSOL's use in filing with the SEC; in our opinion the assumptions, data, methods, and procedures used in the preparation of this report are appropriate for such purpose.

The following table sets forth CONSOL's estimates of the net reserves and future net revenue, as of December 31, 2016, for the audited properties:

	Net Reserves			Future Net Revenue (M$)
	Oil	NGL	Gas		Present Worth
Category	(MBBL)	(MBBL)	(MMCF)	Total	at 10%
Proved Developed Producing	3,137.254	29,625.230	3,368,900.750	2,750,608.598	1,495,044.244
Proved Developed Non-Producing	336.829	1,040.492	109,562.758	90,793.820	58,056.922
Proved Undeveloped	6,536.200	29,865.701	2,349,935.000	1,060,771.125	5,752.768
Total Proved	10,010.283	60,531.422	5,828,398.000	3,902,173.500	1,558,853.750

Totals may not add because of rounding.

The oil volumes shown include crude oil and condensate. Oil volumes are expressed in thousands of barrels (MBBL); a barrel is equivalent to 42 United States gallons. Gas volumes are expressed in millions of cubic feet (MMCF) at standard temperature and pressure bases. The table following this letter sets forth CONSOL's estimates of net reserves and future net revenue by reserves category.

When compared on a field-by-field basis, some of the estimates of CONSOL are greater and some are less than the estimates of Netherland, Sewell & Associates, Inc. (NSAI). However, in our opinion the estimates shown herein of CONSOL's reserves and future revenue are reasonable when aggregated at the proved level and have been prepared in accordance with the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers (SPE Standards). Additionally, these estimates are within the recommended 10 percent tolerance threshold set forth in the SPE Standards. We are satisfied with the methods and procedures used by CONSOL in preparing the December 31, 2016, estimates of reserves and future revenue, and we saw nothing of an unusual nature that would cause us to take exception with the estimates, in the aggregate, as prepared by CONSOL.

The estimates shown herein are for proved reserves. CONSOL's estimates do not include probable or possible reserves that may exist for these properties, nor do they include any value for undeveloped acreage beyond those tracts for which undeveloped reserves have been estimated. CONSOL has included estimates of proved undeveloped reserves for certain locations that generate positive future net revenue but have negative present worth discounted at 10 percent based on the constant prices and costs discussed in subsequent paragraphs of this letter. These locations have been included based on the operators' declared intent to drill these wells, as evidenced by CONSOL's internal budget, reserves estimates, and price forecast. Reserves categorization conveys the relative degree of certainty; reserves subcategorization is based on development and production status. The estimates of reserves and future revenue included herein have not been adjusted for risk.

Prices used by CONSOL are based on the 12-month unweighted arithmetic average of the first-day-of-the-month price for each month in the period January through December 2016. For oil volumes, the average West Texas Intermediate spot price of $42.75 per barrel is adjusted by field for quality, transportation fees, and market differentials. For gas volumes, the average Henry Hub spot price of $2.481 per MMBTU is adjusted by field for energy content, transportation fees, and market differentials. All prices are held constant throughout the lives of the properties. The average adjusted product prices weighted by production over the remaining lives of the properties are $25.04 per barrel of oil, $15.77 per barrel of NGL, and $1.73 per MCF of gas.

Operating costs used by CONSOL are based on historical operating expense records. These costs include the per-well overhead expenses allowed under joint operating agreements along with estimates of costs to be incurred at and below the district and field levels. Operating costs have been divided into per-well costs and per-unit-of-production costs. Headquarters general and administrative overhead expenses of CONSOL are included to the extent that they are covered under joint operating agreements for the operated properties. Capital costs used by CONSOL are based on authorizations for expenditure and actual costs from recent activity. Capital costs are included as required for workovers, new development wells, and production equipment. Abandonment costs used are CONSOL's estimates of the costs to abandon the wells and production facilities, net of any salvage value. Operating, capital, and abandonment costs are not escalated for inflation.

The reserves shown in this report are estimates only and should not be construed as exact quantities. Proved reserves are those quantities of oil and gas which, by analysis of engineering and geoscience data, can be estimated with reasonable certainty to be economically producible; probable and possible reserves are those additional reserves which are sequentially less certain to be recovered than proved reserves. Estimates of reserves may increase or decrease as a result of market conditions, future operations, changes in regulations, or actual reservoir performance. In addition to the primary economic assumptions discussed herein, estimates of CONSOL and NSAI are based on certain assumptions including, but not limited to, that the properties will be developed consistent with current development plans as provided to us by CONSOL, that the properties will be operated in a prudent manner, that no governmental regulations or controls will be put in place that would impact the ability of the interest owner to recover the reserves, and that projections of future production will prove consistent with actual performance. If the reserves are recovered, the revenues therefrom and the costs related thereto could be more or less than the estimated amounts. Because of governmental policies and uncertainties of supply and demand, the sales rates, prices received for the reserves, and costs incurred in recovering such reserves may vary from assumptions made while preparing these estimates.

It should be understood that our audit does not constitute a complete reserves study of the audited oil and gas properties. Our audit consisted primarily of substantive testing, wherein we conducted a detailed review of all properties. In the conduct of our audit, we have not independently verified the accuracy and completeness of information and data furnished by CONSOL with respect to ownership interests, oil and gas production, well test data, historical costs of operation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production. However, if in the course of our examination something came to our attention that brought into question the validity or sufficiency of any such information or data, we did not rely on such information or data until we had satisfactorily resolved our questions relating thereto or had independently verified such information or data. Our audit did not include a review of CONSOL's overall reserves management processes and practices.

We used standard engineering and geoscience methods, or a combination of methods, including performance analysis, volumetric analysis, and analogy, that we considered to be appropriate and necessary to establish the conclusions set forth herein. As in all aspects of oil and gas evaluation, there are uncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professional judgment.

Supporting data documenting this audit, along with data provided by CONSOL, are on file in our office. The technical persons primarily responsible for conducting this audit meet the requirements regarding qualifications, independence, objectivity, and confidentiality set forth in the SPE Standards. Mr. Richard B. Talley, Jr., a Licensed Professional Engineer in the State of Texas, has been practicing consulting petroleum engineering at NSAI since 2004 and has over 5 years of prior industry experience. Edward C. Roy III, a Licensed Professional Geoscientist in the State of Texas, has been practicing consulting petroleum geoscience at NSAI since 2008 and has over 11 years of prior industry experience. We are independent petroleum engineers, geologists, geophysicists, and petrophysicists; we do not own an interest in these properties nor are we employed on a contingent basis.

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]

NOTE 2—DISCONTINUED OPERATIONS:

In August 2016, CONSOL Energy completed the sale of its Miller Creek Mining Complex and Fola Mining Complex subsidiaries. In the transaction, the buyer acquired the Miller Creek and Fola assets and assumed the Miller Creek and Fola mine closing and reclamation liabilities; in order to equalize the value exchange, CONSOL Energy paid $28,271 cash at closing, which included property taxes associated with the properties sold and other closing costs (a portion of which will be held in escrow for purposes of obtaining the surety bonds required for the the permits to transfer). These amounts were included in Net Cash Provided by Discontinued Investing Activities on the Consolidated Statements of Cash Flow. In addition, CONSOL Energy will pay a total of $17,200 in installments over the next four years. The net loss on sale of $53,130, excluding the related impairment charge discussed below, was included in Loss from Discontinued Operations, net on the Consolidated Statements of Income. Prior to the closing, the Miller Creek and Fola Mining Complexes were classified as held for sale in discontinued operations and in accordance with the accounting guidance for Property, Plant and Equipment, assets held for sale are required to be measured at the lower of the carrying value or fair value less costs to sell. Upon meeting the assets held for sale criteria, the Company determined the carrying value of the Miller Creek and Fola Mining Complexes exceeded the fair value less costs to sell. As a result, an impairment charge of $355,681 was recorded during the year ended December 31, 2016. This impairment is included in the Loss from Discontinued Operations, net on the Consolidated Statements of Income.

In March 2016, CONSOL Energy completed the sale of its membership interests in CONSOL Buchanan Mining Company, LLC (BMC), which owned and operated the Buchanan Mine located in Mavisdale, Virginia; various assets relating to the Amonate Mining Complex located in Amonate, Virginia; Russell County, Virginia coal reserves and Pangburn Shaner Fallowfield coal reserves located in Southwestern, Pennsylvania to Coronado IV LLC ("Coronado"). Various CONSOL Energy assets were excluded from the sale including coalbed methane, natural gas and minerals other than coal, current assets of BMC, certain coal seams, certain surface rights, and the Amonate Preparation Plant. Coronado assumed only specified liabilities and various CONSOL Energy liabilities were excluded and not assumed. The excluded liabilities included BMC’s indebtedness, trade payables and liabilities arising prior to closing, as well as the liabilities of the subsidiaries other than BMC which are parties to the sale. In addition, the buyer agreed to pay CONSOL Energy for Buchanan Mine coal sold outside the U.S. and Canada during the five years following closing a royalty of 20% of any excess of the gross sales price per ton over the following amounts: (1) year one, $75.00 per ton; (2) year two, $78.75 per ton; (3) year three, $82.69 per ton; (4) year four, $86.82 per ton; (5) year five, $91.16 per ton. At closing, the parties entered into several agreements including, among others, agreements relating to the coordination and conduct of gas operations at the mines, an option to purchase the Amonate Preparation Plant and transition services.

The net gain on the sale was $48,468 and was included in the Gain on Sale of Assets in the Consolidated Statements of Income.

In December 2014, CNX Gas Company LLC (CNX Gas Company), wholly-owned subsidiary of CONSOL Energy, finalized an agreement with Columbia Energy Ventures (CEVCO) to sublease from CEVCO approximately 20,000 acres of Utica Shale and Upper Devonian gas rights in Greene and Washington Counties in Pennsylvania and Marshall and Ohio Counties in West Virginia. Up-front bonus consideration of up to $96,106 was to be paid by CONSOL Energy over a five year period, as drilling occurs, in addition to royalties. CONSOL Energy made payments of $9,000 to CEVCO in the year ended December 31, 2016, while $50,969 of payments were made in the year ended December 31, 2015. At December 31, 2016, the amounts recorded in Other Current Liabilities and Other Long-Term Liabilities both on a discounted basis were $3,947 and $26,461, respectively. At December 31, 2015, the amounts recorded in Other Current Liabilities and Other Long-Term Liabilities on a discounted basis were $8,349 and $29,333, respectively.

In December 2014, CONSOL Energy completed the sale of its industrial supplies subsidiary to an unrelated third party for expected net proceeds of approximately $51,000, of which $44,035 was received and included in cash flows from investing activities during the year ended December 31, 2014. In connection with the sale, CONSOL Energy signed a supply agreement under which, among other things, it will continue to purchase certain goods exclusively from the new entity for a period of at least three years. CONSOL Energy recorded a net loss on the sale of $30,845, which was included in Gain on Sale of Assets in the Consolidated Statements of Income.

A valuation allowance is required when it is more likely than not that all or a portion of a deferred tax asset will not be realized. All available evidence, both positive and negative, must be considered in determining the need for a valuation allowance. For the years ended December 31, 2016 and 2015, positive evidence considered included financial earnings generated over the past three years for certain subsidiaries, reversals of financial to tax temporary differences and the implementation of and/or ability to employ various tax planning strategies. Negative evidence included financial and tax losses generated in prior periods, the inability to achieve forecasted results for those periods and the expectation that future financial results from normal operations would not be sufficient to support full utilization of certain tax credits within the foreseeable future. CONSOL Energy continues to report, on an after federal tax basis, a deferred tax asset related to state operating losses of $74,310 with a related valuation allowance of $60,488 at December 31, 2016. The deferred tax asset related to state operating losses, on an after tax adjusted basis, was $76,171 with a related valuation allowance of $42,983 at December 31, 2015. A review of positive and negative evidence regarding these tax benefits concluded that the valuation allowances for various CONSOL Energy subsidiaries was warranted. The net operating losses expire at various times between 2017 and 2036. A valuation allowance on foreign tax credits of $39,850 and $25,903 has been recorded at December 31, 2016 and 2015, respectively. The foreign tax credits expire at various times between 2021 and 2023. A valuation allowance on charitable contribution carry-forwards of $5,051 has been recorded for 2016. The charitable contributions carry-forwards expire at various times between 2018 and 2021. No such valuation allowance was recorded for 2015.

The deferred tax assets attributable to the state tax effect of future deductible temporary differences for certain CONSOL Energy subsidiaries with histories of financial and tax losses were also reviewed for positive and negative evidence regarding the realization of the deferred tax assets. A valuation allowance of $10,591 and $9,420 on an after federal tax adjusted basis has also been recorded for 2016 and 2015, respectively.

During 2016, the deferred tax asset relating to federal alternative minimum tax credits increased $76,750, to $219,872 at December 31, 2016 from $143,122 at December 31, 2015. This increase was primarily attributable to restoring previously monetized alternative minimum tax credits. This restoration was created by an agreement reached with the IRS to accelerate certain tax depreciation deductions in exchange for forgoing previously claimed alternative minimum tax credit monetization. At December 31, 2016, a valuation allowance of $166,798 was recorded against these alternative minimum tax credits, based on management's view that negative evidence with respect to their realizability outweighed positive evidence. There was no such valuation allowance at December 31, 2015. These credits do not expire and will be able to be fully utilized when sufficient operating income is generated by the Company.

Management will continue to assess the potential for realized deferred tax assets based upon income forecast data and the feasibility of future tax planning strategies and may record adjustments to valuation allowances against deferred tax assets in future periods, as appropriate, that could materially impact net income.

The following is a reconciliation, stated as a percentage of pretax income, of the United States statutory federal income tax rate to CONSOL Energy's effective tax rate:

	For the Years Ended December 31,

As part of CONSOL Energy's IRS examination of the tax years 2010-2013, bonus depreciation was claimed resulting in a net cash refund of $92,000. The bonus depreciation deduction adversely impacts earnings by reducing the Company's percentage depletion adjustment on its mining operations and reducing the Section 199 manufacturing deduction in the years 2008-2012. This resulted in a net non-cash charge to earnings of $36,619.

A reconciliation of the beginning and ending gross amounts of unrecognized tax benefits is as follows:

	For the Years Ended
	December 31,
	2016			2015
Balance at beginning of period	$	12,702		$	4,265
Increase in unrecognized tax benefits resulting from tax positions taken during current period	666			—
Increase in unrecognized tax benefits resulting from tax positions taken during prior periods	—			8,437
Reduction of unrecognized tax benefits as a result of a settlement with taxing authorities	(4,265		)	—
Balance at end of period	$	9,103		$	12,702

If these unrecognized tax benefits were recognized, $666 and $4,265 would affect CONSOL Energy's effective income tax rate for 2016 and 2015, respectively.

CONSOL Energy and its subsidiaries file income tax returns in the United States and returns within various states and Canadian jurisdictions. With few exceptions, the Company is no longer subject to United States federal, state, local or non-U.S. income tax examinations by tax authorities for the years before 2010.

CONSOL Energy recognizes interest accrued related to unrecognized tax benefits in its interest expense. As of December 31, 2016 and 2015, the Company had an accrued liability of $305 and $53, respectively, for interest related to uncertain tax positions. Interest expense of $252 and $53 was recorded in the Company's Consolidated Statements of Income for the years ended December 31, 2016 and 2015, respectively. During the years ended December 31, 2016 and 2015, CONSOL Energy paid no interest related to income tax deficiencies.

CONSOL Energy recognizes penalties accrued related to uncertain tax positions in its income tax expense. As of December 31, 2016 and 2015, CONSOL Energy had no accrued liabilities for tax penalties.

NOTE 5— STOCK REPURCHASE:

In December 2014, CONSOL Energy’s Board of Directors approved a stock repurchase program under which CONSOL Energy could have purchased up to $250,000 of its common stock over a two year period. Under the terms of the program, CONSOL Energy was permitted to make repurchases in the open market, in privately negotiated transactions, accelerated repurchase programs or in structured share repurchase programs. Any repurchases of common stock were to be funded from available cash on hand or short-term borrowings. The program did not obligate CONSOL Energy to acquire any particular amount of common stock, and could have been modified or suspended at any time at the Company’s discretion. The program was conducted in compliance with applicable legal requirements and within the limits imposed by any credit agreement, receivables purchase agreement or indenture and was subject to market conditions and other factors. No shares were repurchased under this program during the year ended December 31, 2016. During the year ended December 31, 2015, 2,213,100 shares were repurchased and retired at an average price of $32.37 per share.

Industry Participation Agreements

CONSOL Energy had two significant industry participation agreements (referred to as "joint ventures" or "JVs") that provided drilling and completion carries for the Company's retained interests.

CNX Gas Company is party to a joint development agreement with Hess Ohio Developments, LLC (Hess) with respect to approximately 155 thousand net Utica Shale acres in Ohio in which each party has a 50% undivided interest. Under the agreement, as amended, Hess was obligated to pay a total of approximately $335,000 in the form of a 50% drilling carry of certain CONSOL Energy working interest obligations as the acreage is developed. As of December 31, 2016, Hess' entire carry obligation has been met.

CNX Gas Company was party to a joint development agreement with Noble Energy, Inc. (Noble) with respect to approximately 700 thousand net Marcellus Shale oil and gas acres in West Virginia and Pennsylvania, in which each party owned a 50% undivided interest. On October 29, 2016, CNX Gas entered into an Exchange Agreement with Noble Energy, which terminated the joint development agreement related to the jointly owned gas assets held in connection with the joint venture with Noble and divided such jointly owned gas assets among CNX Gas and Noble Energy. The transactions contemplated by the Exchange Agreement was closed on December 1, 2016 with an effective date of October 1, 2016. As part of the exchange: each party will own and operate a 100% interest in its properties and wells in two separate operating areas; each party will have independent control and flexibility with respect to the scope and timing of future development over its operating area; and all acreage operated by CONSOL Energy and Noble Energy, Inc. in their respective operating areas will remain fully dedicated to CONE Midstream Partners LP. Cash proceeds of approximately $213,295 were received at closing and are included in cash flows from investing activities in the Consolidated Statements of Cash Flows. The exchange was accounted for as a mineral conveyance, thus no gain or loss was recorded in connection with the transaction.

Short-Term Notes Payable

Short-term Debt [Abstract]

Short-Term Notes Payable:

SHORT-TERM NOTES PAYABLE:

CONSOL Energy's current senior secured credit agreement expires on June 18, 2019. The credit facility allows for up to $2,000,000 of borrowings, which includes a $750,000 letters of credit sub-limit. CONSOL Energy can also request an additional $500,000 increase in the aggregate borrowing limit amount.

The current facility is secured by substantially all of the assets of CONSOL Energy and certain of its subsidiaries. Fees and interest rate spreads are based on the percentage of facility utilization, measured quarterly. Availability under the facility is limited to a borrowing base, which is determined by the lenders syndication agent and approved by the required number of lenders in good faith by calculating a value of CONSOL Energy's proved natural gas reserves.

The current facility contains a number of affirmative and negative covenants that limit the Company's ability to dispose of assets, make investments, purchase or redeem CONSOL Energy common stock, pay dividends, merge with another corporation and amend, modify or restate the senior unsecured notes. In April 2016, the facility was amended to require that the Company must: (i) prepay outstanding loans under the revolving credit facility to the extent that cash on hand exceeds $150,000 for two consecutive business days; (ii) mortgage 85% of its proved reserves and 80% of its proved developed producing reserves, in each case, which are included in the borrowing base; (iii) maintain applicable deposit, securities and commodities accounts with the lenders or affiliates thereof; and (iv) enter into control agreements with respect to such applicable accounts. In addition, the Company pledged the equity interest it holds in CONE Gathering, LLC and CONE Midstream Partners, LP as collateral to secure loans under the credit agreement.

The facility also requires that CONSOL Energy maintains a minimum interest coverage ratio of no less than 2.50 to 1.00, which is calculated as the ratio of Adjusted EBITDA to cash interest expense of CONSOL Energy and certain of its subsidiaries, measured quarterly. CONSOL Energy must also maintain a minimum current ratio of no less than 1.00 to 1.00, which is calculated as the ratio of current assets, plus revolver availability, to current liabilities, excluding borrowings under the revolver, measured quarterly. At December 31, 2016, the interest coverage ratio was 3.49 to 1.00 and the current ratio was 2.59 to 1.00. Further, the credit facility allows unlimited investments in joint ventures for the development and operation of natural gas gathering systems and permits CONSOL Energy to separate its E&P and coal businesses if the leverage ratio (which is, essentially, the ratio of debt to EBITDA) of the E&P business immediately after the separation would not be greater than 2.75 to 1.00. The calculation of all of the ratios exclude CNX Coal Resources LP (CNXC).

At December 31, 2016, the $2,000,000 facility had no borrowings outstanding and $325,676 of letters of credit outstanding, leaving $1,674,324 of unused capacity. At December 31, 2015, the $2,000,000 facility had $952,000 of borrowings outstanding and $258,177 of letters of credit outstanding, leaving $789,823 of unused capacity.

Defined Contribution Pension and Other Postretirement Plans Disclosure [Abstract]

Components of Pension and Other Postretirement Benefit Plans:

NOTE 14—PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS:

Pension:

CONSOL Energy has non-contributory defined benefit retirement plans. Effective December 31, 2015, CONSOL Energy's qualified defined benefit retirement plan was frozen. The benefits for these plans are based primarily on years of service and employees' pay. CONSOL Energy's qualified pension plan allows for lump-sum distributions of benefits earned up until December 31, 2005, at the employees' election.

On September 30, 2014, the qualified pension plan was remeasured to reflect an announced plan amendment that reduced future accruals of pension benefits as of January 1, 2015. The plan amendment called for a hard freeze of the qualified defined benefit pension plan on January 1, 2015 for employees who were under age 40 or had less than 10 years of service as of September 30, 2014. Employees who were age 40 or over and had at least 10 years of service continued in the defined benefit pension plan unchanged. The modifications to the pension plan resulted in a $21,624 reduction in the pension liability.

On August 31, 2015, the qualified pension plan was remeasured to reflect an announced plan amendment that reduced accruals of pension benefits as of January 1, 2016. The plan amendment called for a hard freeze of the qualified defined benefit pension plan on January 1, 2016 for all remaining participants in the plan. The modifications to the pension plan resulted in a $26,352 reduction in the pension liability. The amendment resulted in a remeasurement of the qualified pension plan at August 31, 2015, which increased the pension liability by $17,793.

In the third quarter of 2015, CONSOL Energy remeasured its pension plan as a result of the previously discussed plan amendment. In conjunction with this remeasurement, the method used to estimate the service and interest components of net periodic benefit cost for pension was changed. This change was also made to other postretirement benefits in the fourth quarter during the annual remeasurement of that plan. This change, compared to the previous method, resulted in a decrease in the service and interest components for pension cost in the third quarter. Historically, CONSOL Energy estimated these service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. CONSOL Energy has elected to utilize a full yield curve approach in the estimation of these components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. This change was made to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. This change is immaterial to CONSOL's financial statements. CONSOL Energy has accounted for this change as a change in accounting estimate that is inseparable from a change in accounting principle and, accordingly, accounted for it prospectively.

According to the Defined Benefit Plans Topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification, if the lump sum distributions made during a plan year, which for CONSOL Energy is January 1 to December 31, exceed the total of the projected service cost and interest cost for the plan year, settlement accounting is required. Lump sum payments exceeded this threshold during the years ended December 31,2016, 2015, and 2014. Accordingly, CONSOL Energy recognized settlement expense of $22,196, $19,053, and $29,095 for the years ended December 31,2016, 2015 and 2014 respectively, in Other Costs - Miscellaneous Operating Expense in the Consolidated Statements of Income. The settlement charges resulted in remeasurements of the pension plan during 2016, 2015 and 2014.

Other Postretirement Benefit Plans:

Certain subsidiaries of CONSOL Energy provide medical and prescription drug benefits to retired employees covered by the Coal Industry Retiree Health Benefit Act of 1992 (the Coal Act). Represented hourly employees are eligible to participate based upon the terms of the National Bituminous Coal Wage Agreement of 2011.

On September 30, 2014, the Salaried OPEB plan and Production and Maintenance (P&M) OPEB plans were remeasured to reflect an announced plan amendment that reduced retiree medical and life insurance benefits as of September 30, 2014. Effective September 30, 2014, no retiree medical, prescription drug or life benefits were to be provided to active employees. Salaried and P&M retirees as of September 30, 2014 were to continue in the OPEB plans for a maximum period up to December 31, 2019 and coverage thereafter was eliminated (see below for information on an additional amendment made to these plans in 2015). The Company elected to make cash transition payments totaling approximately $46,282 to the active employees whose retiree medical, prescription drug and life insurance benefits were eliminated by the changes to the OPEB plans. These cash payments are not considered to be post-retirement benefits, and as such, they are not reflected in the actuarial calculations related to the OPEB plans. The amendment to the OPEB plans resulted in a $315,439 reduction in the OPEB liability and a curtailment gain of $35,633.

On May 31, 2015, the Salaried OPEB and P&M OPEB plans were remeasured to reflect another plan amendment which eliminated Salaried and P&M OPEB benefits at December 31, 2015. The amendment to the OPEB plans resulted in a $43,598 reduction in the OPEB liability. The amendment also resulted in a remeasurement of the OPEB plan at May 31, 2015, which decreased the liability by $1,070. CONSOL Energy recognized income of $235,541 related to amortization of prior service credit, coupled with recognition of actuarial losses in PA Mining Operations Costs - Operating and Other Costs and Other Costs - Miscellaneous Operating Expense in the Consolidated Statements of Income for the year ended December 31, 2015 as a result of the changes made to the Salaried and P&M OPEB plans.

The Company will incur savings from cost containment changes related to pharmacy benefits, which were implemented on January 1, 2017, and increased member responsibility when using out-of-network providers and facilities, which will be implemented on March 27, 2017. These plan amendments resulted in a $28,164 reduction in the OPEB liability during the year ended December 31, 2016.

The reconciliation of changes in the benefit obligation, plan assets and funded status of these plans at December 31, 2016 and 2015 is as follows:

CONSOL Energy utilizes a corridor approach to amortize actuarial gains and losses that have been accumulated under the Pension Plan. Cumulative gains and losses that are in excess of 10% of the greater of either the projected benefit obligation (PBO) or the market-related value of plan assets are amortized over the expected remaining future lifetime of all plan participants for the Pension plan.

CONSOL Energy also utilizes a corridor approach to amortize actuarial gains and losses that have been accumulated under the OPEB Plan. Cumulative gains and losses that are in excess of 10% of the greater of either the accumulated postretirement benefit obligation (APBO) or the market-related value of plan assets are amortized over the average future remaining lifetime of the current inactive population for the OPEB plan.

The following table provides information related to pension plans with an accumulated benefit obligation in excess of plan assets:

	As of December 31,
	2016		2015
Projected benefit obligation	$	747,881	$	763,407
Accumulated benefit obligation	$	745,793	$	761,124
Fair value of plan assets	$	632,434	$	669,039

Assumptions:

The weighted-average assumptions used to determine benefit obligations are as follows:

	Pension Benefits				Other Postretirement Benefits
	For the Year Ended				For the Year Ended
	December 31,				December 31,
	2016		2015		2016		2015
Discount rate	4.31	%	4.50	%	4.22	%	4.50	%
Rate of compensation increase	3.90	%	3.80	%	—		—

The discount rates are determined using a Company-specific yield curve model (above-mean) developed with the assistance of an external actuary. The Company-specific yield curve models (above-mean) use a subset of the expanded bond universe to determine the Company-specific discount rate. Bonds used in the yield curve are rated AA by Moody's or Standard & Poor's as of the measurement date. The yield curve models parallel the plans' projected cash flows, and the underlying cash flows of the bonds included in the models exceed the cash flows needed to satisfy the Company plans.

The weighted-average assumptions used to determine net periodic benefit costs are as follows:

	Pension Benefits at						Other Postretirement Benefits at
	December 31,						December 31,
	2016		2015		2014		2016		2015		2014
Discount rate	4.52	%	4.07	%	4.87	%	4.50	%	4.03	%	4.88	%
Expected long-term return on plan assets	7.25	%	7.75	%	7.75	%	—		—		—
Rate of compensation increase	3.80	%	3.80	%	4.21	%	—		—		—

The long-term rate of return is the sum of the portion of total assets in each asset class held multiplied by the expected return for that class, adjusted for expected expenses to be paid from the assets. The expected return for each class is determined using the plan asset allocation at the measurement date and a distribution of compound average returns over a twenty year time horizon. The model uses asset class returns, variances and correlation assumptions to produce the expected return for each portfolio. The return assumptions used forward-looking gross returns influenced by the current Treasury yield curve. These returns recognize current bond yields, corporate bond spreads and equity risk premiums based on current market conditions.

The assumed health care cost trend rates are as follows:

	At December 31,
	2016		2015		2014
Health care cost trend rate for next year	6.31	%	6.49	%	6.03	%
Rate to which the cost trend is assumed to decline (ultimate trend rate)	4.50	%	4.50	%	4.50	%
Year that the rate reaches ultimate trend rate	2038		2038		2026

Assumed health care cost trend rates have a significant effect on the amounts reported for the medical plans. A one-percentage point change in assumed health care cost trend rates would have the following effects:

	1 Percentage		1 Percentage
	Point Increase		Point Decrease
Effect on total of service and interest cost components	$	3,659	$	(3,053	)
Effect on accumulated postretirement benefit obligation	$	84,381	$	(71,751	)

Plan Assets:

The Company’s overall investment strategy is to meet current and future benefit payment needs through diversification across asset classes, fund strategies and fund managers to achieve an optimal balance between risk and return and between income and growth of assets through capital appreciation. Consistent with the objectives of the Trust and in consideration of the Trust’s current funded status and the current level of market interest rates, the Retirement Board has approved an asset allocation strategy that will change over time in response to future improvements in the Trust’s funded status and/or changes in market interest rates. Such changes in asset allocation strategy are intended to allocate additional assets to the fixed income asset class should the Trust’s funded status improve. In this framework, the current target allocation for plan assets are 26% U.S. equity securities, 16.5% non-U.S. equity securities, 7.5% global equity securities and 50% fixed income. Both the equity and fixed income portfolios are comprised of both active and passive investment strategies. The Trust is primarily invested in Mercer Common Collective Trusts. Equity securities consist of investments in large and mid/small cap companies with non-U.S. equities being derived from both developed and emerging markets. Fixed income securities consist of U.S. as well as international instruments, including emerging markets. The core domestic fixed income portfolios invest in government, corporate, asset-backed securities and mortgage-backed obligations. The average quality of the fixed income portfolio must be rated at least “investment grade” by nationally recognized rating agencies. Within the fixed income asset class, investments are invested primarily across various strategies such that its overall profile strongly correlates with the interest rate sensitivity of the Trust’s liabilities in order to reduce the volatility resulting from the risk of changes in interest rates and the impact of such changes on the Trust’s overall financial status. Derivatives, interest rate swaps, options and futures are permitted investments for the purpose of reducing risk and to extend the duration of the overall fixed income portfolio; however, they may not be used for speculative purposes. All or a portion of the assets may be invested in mutual funds or other commingled vehicles so long as the pooled investment funds have an adequate asset base relative to their asset class; are invested in a diversified manner; and have management and/or oversight by an Investment Advisor registered with the SEC. The Retirement Board, as appointed by the CONSOL Energy Board of Directors, reviews the investment program on an ongoing basis including asset performance, current trends and developments in capital markets, changes in Trust liabilities and ongoing appropriateness of the overall investment policy.

In May 2015, the FASB issued an Accounting Standards Update that removes the requirement to categorize within the fair value hierarchy investments for which fair values are estimated using the net asset value practical expedient provided by Accounting Standards Codification 820, Fair Value Measurement. This new guidance is effective for public entities for fiscal years beginning after December 15, 2015. In accordance with this Update, certain investments in 2016 and 2015 that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified as Level 1, 2 or 3 in the below fair value hierarchy but are included in the total.

The fair values of plan assets at December 31, 2016 and 2015 by asset category are as follows:

(b) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy but are included in the total.

There are no investments in CONSOL Energy stock held by these plans at December 31, 2016 or 2015.

There are no assets in the other postretirement benefit plans at December 31, 2016 or 2015.

Cash Flows:

If necessary, CONSOL Energy intends to contribute to the pension trust using prudent funding methods. However, the Company does not expect to contribute to the pension plan trust in 2017. Pension benefit payments are primarily funded from the trust. CONSOL Energy expects to pay benefits of $2,904 from the non-qualified pension plan in 2017. CONSOL Energy does not expect to contribute to the other postemployment plan in 2017 and intends to pay benefit claims as they are due.

The following benefit payments, reflecting expected future service, are expected to be paid:

			Other

Postemployment Benefits [Abstract]

Coal Workers' Pneumoconiosis (CWP) and Workers' Compensation:

COAL WORKERS’ PNEUMOCONIOSIS (CWP) AND WORKERS’ COMPENSATION:

Under the Federal Coal Mine Health and Safety Act of 1969, as amended, CONSOL Energy is responsible for medical and disability benefits to employees and their dependents resulting from occurrences of coal workers' pneumoconiosis disease. CONSOL Energy is also responsible under various state statutes for pneumoconiosis benefits. CONSOL Energy primarily provides for these claims through a self-insurance program. The calculation of the actuarial present value of the estimated pneumoconiosis obligation is based on an annual actuarial study by independent actuaries and uses assumptions regarding disability incidence, medical costs, indemnity levels, mortality, death benefits, dependents and interest rates which are derived from actual company experience and outside sources. Recent legislative changes have not been favorable for CWP. Although these changes have not had a significant impact on the liability, CONSOL has noticed an increase in claims. Actuarial gains or losses can result from differences in incident rates and severity of claims filed as compared to original assumptions.

CONSOL Energy must also compensate individuals who sustain employment-related physical injuries or some types of occupational diseases and, on some occasions, for costs of their rehabilitation. Workers' compensation laws will also compensate survivors of workers who suffer employment-related deaths. Workers' compensation laws are administered by state agencies, and each state has its own set of rules and regulations regarding compensation that is owed to an employee that is injured in the course of employment. CONSOL Energy primarily provides for these claims through a self-insurance program. CONSOL Energy recognizes an actuarial present value of the estimated workers' compensation obligation calculated by independent actuaries. The calculation is based on claims filed and an estimate of claims incurred but not yet reported as well as various assumptions, including discount rate, future healthcare trend rate, benefit duration and recurrence of injuries. Actuarial gains or losses associated with workers' compensation have resulted from discount rate changes and differences in claims experience and incident rates as compared to prior assumptions.

(Income) expense attributable to discontinued operations included in the CWP net periodic cost was $(1,290), $297 and $87 for the years ended December 31, 2016, 2015 and 2014, respectively.

On March 31, 2016, CONSOL Energy completed the sale of its membership interests in BMC (see Note 2 - Discontinued Operations). As a result of the sale, certain obligations of the CWP plan were transferred to the buyer. This transfer triggered a curtailment gain of $1,307. The curtailment resulted in a plan remeasurement increasing plan liabilities by $7,713 at March 31, 2016.

The following are amounts included in accumulated other comprehensive income that are expected to be recognized in 2017 net periodic benefit costs:

				Workers'
	CWP			Compensation
	Benefits			Benefits
Actuarial gain recognition	$	(7,631	)	$	(610	)

CONSOL Energy utilizes a corridor approach to amortize actuarial gains and losses that have been accumulated under the Workers’ Compensation and CWP plans. Cumulative gains and losses that are in excess of 10% of the greater of either the estimated liability or the market-related value of plan assets are amortized over the expected average remaining future service of the current active membership of the Workers’ Compensation and CWP plans.

Assumptions:

The weighted-average discount rates used to determine benefit obligations and net periodic cost (benefit) are as follows:

	CWP						Workers' Compensation
	For the Years Ended						For the Years Ended
	December 31,						December 31,
	2016		2015		2014		2016		2015		2014
Benefit obligations	4.40	%	4.60	%	4.21	%	4.05	%	4.26	%	3.84	%
Net periodic cost	4.60	%	4.21	%	4.75	%	4.26	%	3.84	%	4.57	%

Discount rates are determined using a Company-specific yield curve model (above-mean) developed with the assistance of an external actuary. The Company-specific yield curve models (above-mean) use a subset of the expanded bond universe to determine the Company-specific discount rate. Bonds used in the yield curve are rated AA by Moody's or Standard & Poor's as of the measurement date. The yield curve models parallel the plans' projected cash flows, and the underlying cash flows of the bonds included in the models exceed the cash flows needed to satisfy the Company's plans.

Cash Flows:

CONSOL Energy does not intend to make contributions to the CWP or Workers' Compensation plans in 2017, but it intends to pay benefit claims as they become due.

The following benefit payments, which reflect expected future claims as appropriate, are expected to be paid:

			Workers' Compensation
	CWP		Total		Actuarial		Other
	Benefits		Benefits		Benefits		Benefits
2017	$	10,763	$	15,897	$	12,416	$	3,481

OTHER EMPLOYEE BENEFIT PLANS: [Abstract]

Compensation and Employee Benefit Plans [Text Block]

NOTE 16—OTHER EMPLOYEE BENEFIT PLANS:

UMWA Benefit Trusts:

The Coal Act created two multi-employer benefit plans: (1) the United Mine Workers of America Combined Benefit Fund (the Combined Fund) into which the former UMWA Benefit Trusts were merged, and (2) the United Mine Workers of America 1992 Benefit Plan (1992 Benefit Plan). CONSOL Energy accounts for required contributions to these multi-employer trusts as expense when incurred.

The Combined Fund provides medical and death benefits for all beneficiaries of the former UMWA Benefit Trusts who were actually receiving benefits as of July 20, 1992. The 1992 Benefit Plan provides medical and death benefits to orphan UMWA-represented members eligible for retirement on February 1, 1993, and for those who retired between July 20, 1992 and September 30, 1994. The Coal Act provides for the assignment of beneficiaries to former employers and the allocation of unassigned beneficiaries (referred to as orphans) to companies using a formula set forth in the Coal Act. The Coal Act requires that responsibility for funding the benefits to be paid to beneficiaries be assigned to their former signatory employers or related companies. This cost is recognized when contributions are assessed. CONSOL Energy's total contributions under the Coal Act were $8,455, $9,239 and $10,121 for the years ended December 31, 2016, 2015 and 2014, respectively. Based on available information at December 31, 2016, CONSOL Energy's obligation for the Combined Fund and 1992 Benefit Plans is estimated to be approximately $93,795.

Pursuant to the provisions of the Tax Relief and Healthcare Act of 2006 (the 2006 Act) and the 1992 Benefit Plan, CONSOL Energy is required to provide security in an amount based on the annual cost of providing health care benefits for all individuals receiving benefits from the 1992 Benefit Plan who are attributable to CONSOL Energy, plus all individuals receiving benefits from an individual employer plan maintained by CONSOL Energy who are entitled to receive such benefits. In accordance with the terms of the 2006 Act and the 1992 Benefit Plan, CONSOL Energy must secure its obligations by posting letters of credit, which were $19,170, $21,473 and $21,394 at December 31, 2016, 2015 and 2014, respectively. The 2016, 2015 and 2014 security amounts were based on the annual cost of providing health care benefits and included a reduction in the number of eligible employees.

Investment Plan:

CONSOL Energy has an investment plan available to most non-represented employees. Throughout the year ended December 31, 2016, the Company's matching contribution was 6% of eligible compensation contributed by eligible employees. In conjunction with the qualified pension plan changes in 2015, the Company contributed an additional 3% of eligible compensation into the 401(k) plan accounts for employees hired or rehired on or after October 1, 2014 or who were under age 40 or had less than 10 years of service with the Company as of September 30, 2014. This additional contribution was eliminated on January 1, 2016. The Company may also make discretionary contributions to the Plan ranging from 1% to 6% (1% to 4% prior to January 1, 2016) of eligible compensation for eligible employees (as defined by the Plan). Discretionary contributions made by the Company were $12,260 for the year ended December 31, 2016. There were no such discretionary contributions made by the Company for the years ended December 31, 2015 and 2014. Total payments and costs were $20,784, $20,058 and $18,341 for the years ended December 31, 2016, 2015 and 2014, respectively.

Long-Term Disability:

CONSOL Energy has a Long-Term Disability Plan available to all eligible full-time salaried employees. The benefits for this plan are based on a percentage of monthly earnings, offset by all other income benefits available to the disabled.

	For the Years Ended
	December 31,
	2016			2015			2014
Benefit cost	$	2,128		$	2,619		$	2,213

Stock Based Compensation

Share-based Compensation [Abstract]

Disclosure of Compensation Related Costs, Share-based Payments [Text Block]

STOCK-BASED COMPENSATION:

CONSOL Energy adopted the CONSOL Energy Inc. Equity Incentive Plan (the Equity Incentive Plan) on April 7, 1999. The Equity Incentive Plan provides for grants of stock-based awards to key employees and to non-employee directors. Amendments to the Equity Incentive Plan have been adopted and approved by the Board of Directors and the Company's Shareholders since the commencement of the plan. Most recently, in May 2016, the Board of Directors and the Company's Shareholders adopted and approved a 10,550,000 increase to the total number of shares available for issuance, which brought the total number of shares of common stock that can be covered by grants to 42,350,000. At December 31, 2016, 8,733,169 shares of common stock remain available for all awards. The Equity Incentive Plan provides that the aggregate number of shares available for issuance will be reduced by one share for each share issued in settlement of stock options and by 1.62 for each share issued in settlement of Performance Share Units (PSUs) or Restricted Stock Units (RSUs). No award of stock options may be exercised under the Equity Incentive Plan after the tenth anniversary of the effective date of the award.

For only those shares expected to vest, CONSOL Energy recognizes stock-based compensation costs on a straight-line basis over the requisite service period of the award, which is generally the vesting term. Awards granted in 2014 vest immediately if granted to retiree-eligible employees who are aged 62 and older. Awards granted in 2014 vest at the end of one year when granted to employees aged 55 to 62 and who have also completed ten years of service. Awards granted in 2014 vest over a three-year term at 33% per year for all other employees. Awards granted in 2015 vest over a three-year term at 33% per year. Options and RSUs granted in 2016 vest over a three-year term at 33% per year. Performance share units granted in 2016 vest over a five-year term at 20% per year subject to performance conditions. If an employee leaves the Company, all unvested shares are forfeited. The vesting of all awards will accelerate in the event of death and disability and may accelerate upon a change in control of CONSOL Energy. See each specific award section for special vesting terms related to non-employee directors and other specific awards. The total stock-based compensation expense recognized during the years ended December 31, 2016, 2015 and 2014 was $31,483, $24,513 and $41,877, respectively. The related deferred tax benefit totaled $11,255, $9,229 and $15,243, for the years ended December 31, 2016, 2015 and 2014, respectively.

As of December 31, 2016, CONSOL Energy has $40,234 of unrecognized compensation cost related to all nonvested stock-based compensation awards, which is expected to be recognized over a weighted-average period of 2.73 years. When stock options are exercised and restricted and performance stock unit awards become vested, the issuances are made from CONSOL Energy's common stock shares.

Stock Options:

CONSOL Energy examined its historical pattern of option exercises in an effort to determine if there were any discernable activity patterns based on certain employee populations. From this analysis, CONSOL Energy identified two distinct employee populations and used the Black-Scholes option pricing model to value the options for each of the employee populations. The expected term computation presented in the table below is based upon a weighted average of the historical exercise patterns and post-vesting termination behavior of the two populations. The risk-free interest rate was determined for each vesting tranche of an award based upon the calculated yield on U.S. Treasury obligations for the expected term of the award. The expected forfeiture rate is based upon historical forfeiture activity. A combination of historical and implied volatility is used to determine expected volatility and future stock price trends. The total fair value of options granted during the year ended December 31, 2016 was $19,305, based on the following assumptions and weighted average fair values:

	December 31,
	2016
Weighted average fair value of grants	$	5.73
Risk-free interest rate	1.13		%
Expected dividend yield	0.27		%
Expected forfeiture rate	2.00		%
Expected volatility	61.09		%
Expected term in years	4.90

CONSOL Energy did not grant stock option awards during the years ended December 31, 2015 or 2014.

A summary of the status of stock options granted is presented below:

				Weighted

			Weighted	Remaining	Aggregate
			Average	Contractual	Intrinsic

Exercisable at December 31, 2016	2,990,263		$43.12	2.57	$	—

At December 31, 2016, there are 5,888,075 employee stock options outstanding under the Equity Incentive Plan. Non-employee director stock options vest one year after the grant date. There are 320,738 fully vested stock options outstanding under these grants.

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between CONSOL Energy's closing stock price on the last trading day of the year ended December 31, 2016 and the option's exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on December 31, 2016. This amount varies based on the fair market value of CONSOL Energy's stock. No options were exercised during the year ended December 31, 2016. The total intrinsic value of options exercised for the years ended December 31, 2015 and 2014 was $2,744 and $14,545, respectively.

Cash received from option exercises for the years ended December 31, 2015 and 2014 was $8,281 and $15,011, respectively. The tax impact from option exercises totaled $208 and $2,629 for the years ended December 31, 2015 and 2014, respectively. This excess tax benefit is included in cash flows from financing activities in the Consolidated Statements of Cash Flows.

Restricted Stock Units:

Under the Equity Incentive Plan, CONSOL Energy grants certain employees and non-employee directors restricted stock unit awards, which entitle the holder to shares of common stock as the award vests. Non-employee director restricted stock units vest at the end of one year. In 2014, restricted stock units were granted that will vest over a five year period unless certain market conditions are met, in which the award will accelerate. Compensation expense is recognized over the vesting period of the units, described above. The total fair value of restricted stock units granted during the years ended December 31, 2016, 2015 and 2014 was $493, $26,550 and $31,360, respectively. The total fair value of restricted stock units vested during the years ended December 31, 2016, 2015 and 2014 was $19,095, $20,793 and $15,686, respectively. The following table represents the nonvested restricted stock units and their corresponding fair value (based upon the closing share price) at the date of grant:

	Number of		Weighted Average

Forfeited	(88,703	)	$30.42
Nonvested at December 31, 2016	663,003		$31.97

Performance Share Units:

Under the Equity Incentive Plan, CONSOL Energy grants certain employees performance share unit awards, which entitle the holder to shares of common stock subject to the achievement of certain market and performance goals. Compensation expense is recognized over the performance measurement period of the units in accordance with the provisions of the Stock Compensation Topic of the FASB Accounting Standards Codification for awards with market and performance vesting conditions. For the PSUs issued in 2014 and 2015, achievement of the market goals is not probable, but achievement of the performance goals is probable. Achievement of the market goals is probable for the first tranche of the PSUs issued in 2016. The total fair value of performance share units granted during the years ended December 31, 2016, 2015 and 2014 was $24,283, $18,771 and $11,853, respectively. No performance share units vested during the year ended December 31, 2016. The total fair value of performance share units vested during the years ended December 31, 2015 and 2014 was $20,083 and $18,759, respectively. The following table represents the nonvested performance share units and their corresponding fair value (based upon the closing share price) on the date of grant:

Performance Options:

Under the Equity Incentive Plan in 2010, CONSOL Energy granted certain employees performance options, which entitled the holder to shares of common stock subject to the achievement of certain performance goals. Compensation expense was recognized over the vesting period of the options, described above. The Black-Scholes option valuation model was used to value each tranche separately. No performance options were granted in 2016, 2015, or 2014. No performance options vested in 2016 or 2015. The total fair value of performance options vested during the year ended December 31, 2014 was $4,949. A summary of the status of performance options granted is presented below:

CONSOL Stock Units:

Under the Equity Incentive Plan in 2013, CONSOL Energy granted certain employees CONSOL Stock Unit Awards, which entitled the holder to shares of common stock subject to the achievement of certain market and performance goals. Compensation expense was recognized over the performance measurement period of the units in accordance with the provisions of the Stock Compensation Topic of the FASB Accounting Standards Codification for awards with market and performance vesting conditions. CONSOL Energy used the Monte Carlo methodology to estimate the fair value of the CONSOL Stock Units. The achievement of the market and performance goals was not attained and therefore, all shares were forfeited in 2016. No CONSOL Stock Units were granted in 2016. The total fair value of CONSOL Stock Units granted during the years ended December 31, 2015 and 2014 was $110 and $189 respectively. The following table represents the nonvested CONSOL Stock Unit awards and their corresponding fair value at the grant date:

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

FAIR VALUE OF FINANCIAL INSTRUMENTS:

CONSOL Energy determines the fair value of assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. The fair values are based on assumptions that market participants would use when pricing an asset or liability, including assumptions about risk and the risks inherent in valuation techniques and the inputs to valuations. The fair value hierarchy is based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources (including NYMEX forward curves, LIBOR-based discount rates and basis forward curves), while unobservable inputs reflect the Company's own assumptions of what market participants would use.

The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below:

Level One - Quoted prices for identical instruments in active markets.

Level Two - The fair value of the assets and liabilities included in Level 2 are based on standard industry income approach models that use significant observable inputs, including NYMEX forward curves, LIBOR-based discount rates and basis forward curves.

Level Three - Unobservable inputs significant to the fair value measurement supported by little or no market activity. The significant unobservable inputs used in the fair value measurement of the Company's third party guarantees are the credit risk of the third party and the third party surety bond markets. A significant increase or decrease in these values, in isolation, would have a directionally similar effect resulting in higher or lower fair value measurement of the Company's Level 3 guarantees.

In those cases when the inputs used to measure fair value meet the definition of more than one level of the fair value hierarchy, the lowest level input that is significant to the fair value measurement in its totality determines the applicable level in the fair value hierarchy.

The financial instruments measured at fair value on a recurring basis are summarized below:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

DERIVATIVE INSTRUMENTS:

CONSOL Energy enters into financial derivative instruments to manage its exposure to commodity price volatility. CONSOL Energy de-designated all of its cash flow hedges on December 31, 2014 and accounts for all existing and future gas and NGL commodity hedges on a mark-to-market basis with changes in fair value recorded in current period earnings. In connection with this de-designation, CONSOL Energy froze the balances recorded in Accumulated Other Comprehensive Income at December 31, 2014 and reclassified balances to earnings as the underlying physical transactions occurred. As of December 31, 2016, all gains deferred in OCI have been recognized in earnings.

CONSOL Energy is exposed to credit risk in the event of non-performance by counterparties. The creditworthiness of counterparties is subject to continuing review. The Company has not experienced any issues of non-performance by derivative counterparties.

None of the Company's counterparty master agreements currently require CONSOL Energy to post collateral for any of its positions. However, as stated in the counterparty master agreements, if CONSOL Energy's obligations with one of its counterparties cease to be secured on the same basis as similar obligations with the other lenders under the credit facility, CONSOL Energy would have to post collateral for instruments in a liability position in excess of defined thresholds. All of the Company's derivative instruments are subject to master netting arrangements with our counterparties. CONSOL Energy recognizes all financial derivative instruments as either assets or liabilities at fair value on the Consolidated Balance Sheets on a gross basis.

Each of CONSOL Energy's counterparty master agreements allows, in the event of default, the ability to elect early termination of outstanding contracts. If early termination is elected, CONSOL Energy and the applicable counterparty would net settle all open hedge positions.

The total notional amounts of production of CONSOL Energy's derivative instruments at December 31, 2016 and December 31, 2015 were as follows:

Commitments and Contingencies

NOTE 22—COMMITMENTS AND CONTINGENT LIABILITIES:

CONSOL Energy and its subsidiaries are subject to various lawsuits and claims with respect to such matters as personal injury, wrongful death, damage to property, exposure to hazardous substances, governmental regulations including environmental remediation, employment and contract disputes and other claims and actions arising out of the normal course of business. CONSOL Energy accrues the estimated loss for these lawsuits and claims when the loss is probable and can be estimated. The Company's current estimated accruals related to these pending claims, individually and in the aggregate, are immaterial to the financial position, results of operations or cash flows of CONSOL Energy. It is possible that the aggregate loss in the future with respect to these lawsuits and claims could ultimately be material to the financial position, results of operations or cash flows of CONSOL Energy; however, such amounts cannot be reasonably estimated. The amount claimed against CONSOL Energy is disclosed below when an amount is expressly stated in the lawsuit or claim, which is not often the case. The maximum aggregate amount claimed in those lawsuits and claims, regardless of probability, where a claim is expressly stated or can be estimated, exceeds the aggregate amounts accrued for all lawsuits and claims by approximately $937,421.

The following lawsuits and claims include those for which a loss is probable and an accrual has been recognized.

Hale Litigation: This class action lawsuit was filed on September 23, 2010 in the U.S. District Court in Abingdon, Virginia. The putative class consists of force-pooled unleased gas owners whose ownership of the coalbed methane (CBM) gas was declared to be in conflict with rights of others. The lawsuit seeks a judicial declaration of ownership of the CBM and damages based on allegations CNX Gas Company failed to either pay royalties due to conflicting claimants or deemed lessors or paid them less than required because of the alleged practice of improper below market sales and/or taking alleged improper post-production deductions. On September 30, 2013, the District Judge entered an Order certifying the class, and CNX Gas Company appealed the Order to the U.S. Fourth Circuit Court of Appeals. On August 19, 2014, the Fourth Circuit agreed with CNX Gas Company, reversed the Order certifying the class and remanded the case to the trial court for further proceedings consistent with the decision. On April 23, 2015, Plaintiffs filed a Renewed Motion for Class Certification, and on June 23, 2015, CNX Gas Company filed its Opposition to same. The Court held a hearing on the Motion on September 18, 2015 and has not yet ruled. CONSOL Energy continues to believe this action cannot properly proceed as a class action in any form, believes the case has meritorious defenses, and intends to defend it vigorously. The Company has established an accrual to cover its estimated liability for this case. This accrual is immaterial to the overall financial position of CONSOL Energy and is included in Other Accrued Liabilities on the Consolidated Balance Sheets.

Addison Litigation: This class action lawsuit was filed on April 28, 2010 in the U.S. District Court in Abingdon, Virginia. The putative class consists of gas lessors whose gas ownership is in conflict. The lawsuit seeks a judicial declaration of ownership of the CBM and damages based on the allegations that CNX Gas Company failed to either pay royalties due to these conflicting claimant lessors or paid them less than required because of the alleged practice of improper below market sales and/or taking alleged improper post-production deductions. On September 30, 2013, the District Judge entered an Order certifying the class, and CNX Gas Company appealed the Order to the U.S. Fourth Circuit Court of Appeals. On August 19, 2014, the Fourth Circuit agreed with CNX Gas Company, reversed the Order certifying the class and remanded the case to the trial court for further proceedings consistent with the decision. On April 23, 2015, Plaintiffs filed a Renewed Motion for Class Certification, and on June 23, 2015, CNX Gas Company filed its Opposition to same. The Court held a hearing on the Motion on September 18, 2015 and has not yet ruled. CONSOL Energy continues to believe this action cannot properly proceed as a class action in any form, believes the case has meritorious defenses, and intends to defend it vigorously. The Company has established an accrual to cover its estimated liability for this case. This accrual is immaterial to the overall financial position of CONSOL Energy and is included in Other Accrued Liabilities on the Consolidated Balance Sheets.

The following royalty, land rights and other lawsuits and claims include those for which a loss is reasonably possible, but not probable, and accordingly, an accrual may not have been recognized. These claims are influenced by many factors which prevent the estimation of a range of potential loss. These factors include, but are not limited to, generalized allegations of unspecified damages (such as improper deductions), discovery having not commenced or not having been completed, unavailability of expert reports on damages and non-monetary issues being tried. For example, in instances where a gas lease termination is sought, damages would depend on speculation as to if and when the gas production would otherwise have occurred, how many wells would have been drilled on the lease premises, what their production would be, what the cost of production would be, and what the price of gas would be during the production period. An estimate is calculated, if applicable, when sufficient information becomes available.

Fitzwater Litigation: Two nonunion retired coal miners have sued CONSOL Energy Inc., Fola Coal Company and Consolidation Coal Company in West Virginia Federal Court alleging ERISA violations in the termination of retiree health care benefits. The Plaintiffs contend they relied to their detriment on oral statements and promises of "lifetime health benefits" allegedly made by various members of management during Plaintiffs' employment and that they were allegedly denied access to Summary Plan Documents that clearly reserved to the Company the right to modify or terminate the CONSOL Energy Inc. Retiree Health and Welfare Plan. Plaintiffs request that retiree health benefits be reinstated and seek to represent a class of all nonunion retirees of CONSOL Energy and its subsidiaries. The Company believes it has meritorious defense and intends to vigorously defend this suit.

Virginia Mine Void Litigation: The Company is currently defending three lawsuits naming Consolidation Coal Company (CCC), Island Creek Coal Company (ICCC), CNX Gas Company, and/or CONSOL Energy. The lawsuits were filed in the U.S. District Court for the Western District of Virginia. On October 26, 2015, the trial court granted summary judgment in favor of the defendants in two of the actions upon its finding that plaintiffs' claims are barred by the applicable statutes of limitation. Plaintiffs have appealed both cases to the U.S. Court of Appeals for the Fourth Circuit. Oral argument was held on December 8, 2016. The third case remains pending in the trial court. On January 26, 2016, six mine void lawsuits that have twice before been filed and voluntarily dismissed, were refiled for a third time in state court but have not been served. The Complaints seek damages and injunctive relief in connection with the transfer of water from mining activities at Buchanan Mine into void spaces in inactive ICCC mines adjacent to the Buchanan operations, voids ostensibly underlying plaintiffs’ properties. While some of the plaintiffs have an ownership interest in the coal, others have some interest in one or more of the fee, surface, oil/gas or other mineral estates. The suits allege the water storage precludes access to and has damaged coal, impeded coalbed methane gas production and was made without compensation to the property owners. Plaintiffs seek recovery in tort, contract and trespass assumpsit (quasi-contract). The suits each seek damages between $50,000 and in excess of $100,000 plus punitive damages. The Company intends to vigorously defend these suits.

At December 31, 2016, CONSOL Energy has provided the following financial guarantees, unconditional purchase obligations and letters of credit to certain third parties, as described by major category in the following table. These amounts represent the maximum potential of total future payments that the Company could be required to make under these instruments. These amounts have not been reduced for potential recoveries under recourse or collateralization provisions. Generally, recoveries under reclamation bonds would be limited to the extent of the work performed at the time of the default. No amounts related to these financial guarantees and letters of credit are recorded as liabilities in the financial statements. CONSOL Energy management believes that these guarantees will expire without being funded, and therefore the commitments will not have a material adverse effect on financial condition.

Included in the above table are commitments and guarantees entered into in conjunction with the sale of Consolidation Coal Company and certain of its subsidiaries, which contain all five of its longwall coal mines in West Virginia, and its river operations to a subsidiary of Murray Energy Corporation (Murray Energy). As part of the sales agreement, CONSOL Energy has guaranteed certain equipment lease obligations and coal sales agreements that were assumed by Murray Energy. In the event that Murray Energy would default on the obligations defined in the agreements, CONSOL Energy would be required to perform under the guarantees. If CONSOL Energy would be required to perform, the stock purchase agreement provides various recourse actions. At December 31, 2016 and December 31, 2015, the fair value of these guarantees was $1,362 and $1,228, respectively, and are included in Other Accrued Liabilities on the Consolidated Balance Sheets. The fair value of certain of the guarantees was determined using CONSOL Energy’s risk-adjusted interest rate. Significant increases or decreases in the risk-adjusted interest rates may result in a significantly higher or lower fair value measurement. Coal sales agreement guarantees were valued based on an evaluation of coal market pricing compared to contracted sales price and includes an adjustment for nonperformance risk. No other amounts related to financial guarantees and letters of credit are recorded as liabilities in the financial statements. Significant judgment is required in determining the fair value of these guarantees. The guarantees of the leases and sales agreements are classified within Level 3 of the fair value hierarchy.

As part of the sale of Buchanan Mine (See Note 2 - Discontinued Operations), CONSOL Energy has guaranteed certain equipment lease obligations that were assumed by Coronado. In the event that Coronado would default on the obligations defined in the agreements, CONSOL Energy would be required to perform under the guarantees. 

CONSOL Energy regularly evaluates the likelihood of default for all guarantees based on an expected loss analysis and records the fair value, if any, of its guarantees as an obligation in the consolidated financial statements. 

CONSOL Energy and CNX Gas Company enter into long-term unconditional purchase obligations to procure major equipment purchases, natural gas firm transportation, gas drilling services and other operating goods and services. These purchase obligations are not recorded on the Consolidated Balance Sheets. As of December 31, 2016, the purchase obligations for each of the next five years and beyond were as follows:

Obligations Due	Amount
Less than 1 year	$	209,797
1 - 3 years	285,224
3 - 5 years	243,534
More than 5 years	622,509
Total Purchase Obligations	$	1,361,064

Segment Reporting [Abstract]

Segment Reporting Disclosure [Text Block]

SEGMENT INFORMATION:

CONSOL Energy consists of two principal business divisions: Exploration and Production (E&P) and Pennsylvania (PA) Mining Operations. The principal activity of the E&P division, which includes four reportable segments, is to produce pipeline quality natural gas for sale primarily to gas wholesalers. The E&P division's reportable segments are Marcellus Shale, Utica Shale, Coalbed Methane, and Other Gas. The Other Gas segment is primarily related to shallow oil and gas production and the Chattanooga Shale in Tennessee, neither of which are significant to the Company. It also includes the Company's purchased gas activities, unrealized gain or loss on commodity derivative instruments, exploration and production related other costs, other corporate expenses, selling, general and administrative activities, as well as various other activities assigned to the E&P division but not allocated to each individual segment. The principal activities of the PA Mining Operations division are mining, preparation and marketing of thermal coal, sold primarily to power generators. It also includes selling, general and administrative activities, as well as various other activities assigned to the PA Mining Operations division.

CONSOL Energy’s Other division includes expenses from various corporate and diversified business activities that are not allocated to the E&P or PA Mining Operations divisions. The diversified business activities include coal terminal operations, closed and idle mine activities, water operations, selling, general and administrative activities, as well as various other non-operated activities, none of which are individually significant to the Company. In previous periods, this division included activity from the sales of industrial supplies (this subsidiary was sold in December 2014).

Prior to the sale of the Buchanan Mine on March 31, 2016 and the Fola and Miller Creek Complexes on August 1, 2016 (see Note 2 - Discontinued Operations), CONSOL Energy had a Coal division. The Coal division had three reportable segments; PA Operations, Virginia (VA) Operations and Other Coal. The VA Operations segment included the Buchanan Mine and the Other Coal segment was primarily comprised of the assets and operations of the Fola and Miller Creek Complexes, as well as coal terminal operations, closed and idle mine activities, selling, general and administrative activities and various other non-operated activities. PA Operations now constitutes its own division and reportable segment and the remaining activity in the Other Coal segment became part of CONSOL Energy's diversified business activities in the Other division. Prior periods have been reclassified to align with current period presentation.

In the preparation of the following information, intersegment sales have been recorded at amounts approximating market. Operating profit for each segment is based on sales less identifiable operating and non-operating expenses. Assets are reflected at the division level for E&P and are not allocated between each individual E&P segment. These assets are not allocated to each individual segment due to the diverse asset base controlled by CONSOL Energy, whereby each individual asset may service more than one segment within the division. An allocation of such asset base would not be meaningful or representative on a segment by segment basis.

Guarantor Subsidiaries Financial Information [Abstract]

Additional Financial Information Disclosure [Text Block]

NOTE 24—GUARANTOR SUBSIDIARIES FINANCIAL INFORMATION:

The payment obligations under the $74,470, 8.250% per annum senior notes due April 1, 2020, the $20,611, 6.375% per annum senior notes due March 1, 2021, the $1,854,731, 5.875% per annum senior notes due April 15, 2022, and the $494,344, 8.000% per annum senior notes due April 1, 2023 issued by CONSOL Energy are jointly and severally, and also fully and unconditionally, guaranteed by certain subsidiaries of CONSOL Energy. In accordance with positions established by the Securities and Exchange Commission (SEC), the following financial information sets forth separate financial information with respect to the parent, CNX Gas, a guarantor subsidiary, CNX Coal Resources LP (CNXC), a non-guarantor subsidiary, and the remaining guarantor and non-guarantor subsidiaries. The principal elimination entries include investments in subsidiaries and certain intercompany balances and transactions. CONSOL Energy, the parent, and a guarantor subsidiary manage several assets and liabilities of all other wholly owned subsidiaries. These include, for example, deferred tax assets, cash and other post-employment liabilities. These assets and liabilities are reflected as parent company or guarantor company amounts for purposes of this presentation.

On September 30, 2016, CNXC acquired an additional 5% undivided interest in the Pennsylvania Mining Complex from CONSOL Energy, increasing their total undivided interest to 25%. To account for the acquisition, CNXC recast its consolidated financial statements to retrospectively reflect the additional 5% interest as if the business was owned for all periods presented. This resulted in corresponding retrospective adjustments between the Other Subsidiary Guarantors and the CNXC Non-Guarantor columns below. See Note 25 - Related Party Transactions of the Notes to the Audited Consolidated Financial Statements in Item 8 of this Form 10-K for additional information.

NOTE 25—RELATED PARTY TRANSACTIONS

CONE Gathering LLC and CONE Midstream Partners LP

In September 2011, CNX Gas Company, a wholly owned subsidiary of CONSOL Energy, and Noble Energy, Inc. (Noble Energy), an unrelated third party, formed CONE Gathering LLC (CONE) to develop and operate each company's gas gathering system needs in the Marcellus Shale play. CONSOL Energy accounts for CNX Gas Company's 50% ownership interest in CONE under the equity method of accounting.

In May 2014, CONSOL Energy and Noble Energy (collectively, “the Sponsors”) formed CONE Midstream Partners LP (the Partnership), a master limited partnership, to own, operate, develop and acquire natural gas gathering and other midstream energy assets to service each company’s production in the Marcellus Shale in Pennsylvania and West Virginia. The Partnership's general partner is CONE Midstream GP LLC, a wholly owned subsidiary of CONE.

In September 2014, the Partnership closed its initial public offering of 20,125,000 common units representing limited partnership interests, which included a 2,625,000 common unit over-allotment option that was exercised in full by the underwriters. Following the IPO, CONE had a 2% general partner interest in the Partnership, while each sponsor had a 32.1% limited partner interest. CNX Gas Company accounts for its portion of the earnings in the Partnership under the equity method of accounting.

In November 2016, the Partnership acquired from CONE an additional 25% ownership interest in CONE Midstream DevCo I LP, commonly referred to as the “Anchor Systems.” The transaction included a total purchase consideration of $248,000, comprised of $140,000 in cash and issuance of approximately 5,200,000 common limited partnership units to the Sponsors.  Following the acquisition, CONE continues to have a 2% general partner interest in the Partnership, while each Sponsor’s limited partner interest increased to 33.5%. At December 31, 2016, CNX Gas Company and Noble Energy each continue to own a 50% interest in the assets of CONE that were not contributed to the Partnership.

The following is a summary of the Company's Investment in Affiliates balances included within the Consolidated Balance Sheets associated with CONE and the Partnership, respectively:

	CONE			The Partnership			Total

Additionally, during the year ended December 31, 2015, CONSOL Energy purchased $2,239 of supply inventory from the Partnership. CONSOL Energy did not have any supply inventory purchases from the Partnership during the year ended December 31, 2016.

CNX Coal Resources LP

In July 2015, CNX Coal Resources LP (CNXC) closed its initial public offering of 5,000,000 common units representing limited partnership interests at a price to the public of $15.00 per unit. Additionally, Greenlight Capital entered into a common unit purchase agreement with CNXC pursuant to which Greenlight Capital agreed to purchase, and CNXC agreed to sell, 5,000,000 common units at a price per unit equal to $15.00, which equates to $75,000 in net proceeds. CNXC's general partner is CNX Coal Resources GP, a wholly owned subsidiary of CONSOL Energy. The underwriters of the IPO filing exercised an over-allotment option of 561,067 common units to the public at $15.00 per unit.

In connection with the Initial Public Offering (IPO), CNXC entered into a $400,000 senior secured revolving credit facility with certain lenders and PNC Bank, National Association (PNC), as administrative agent. Obligations under the revolving credit facility are guaranteed by CNXC's subsidiaries (the guarantor subsidiaries) and are secured by substantially all of CNXC's and CNXC's subsidiaries' assets pursuant to a security agreement and various mortgages. Under the new revolving credit facility, CNXC made an initial draw of $200,000, and after origination fees of $3,000, the net proceeds were $197,000.

The total net proceeds related to these transactions that were distributed to CONSOL Energy were $342,711.

In September 2016, CNXC and its wholly owned subsidiary, CNX Thermal Holdings LLC (CNX Thermal), entered into a Contribution Agreement with CONSOL Energy, CONSOL Pennsylvania Coal Company LLC and Conrhein Coal Company (the Contributing Parties) under which CNX Thermal acquired an additional 5% undivided interest in and to the Pennsylvania Mine Complex, in exchange for (i) cash consideration in the amount of $21,500 and (ii) CNXC's issuance of 3,956,496 Class A Preferred Units representing limited partner interests in CNXC at an issue price of $17.01 per Class A preferred Unit (the "Class A Preferred Unit Issue Price"), or an aggregate $67,300 in equity consideration. The Class A Preferred Unit Issue Price was calculated as the volume-weighted average trading price of CNXC's common units (the "Common Units") over the trailing 15-day trading period ending on September 29, 2016 (or $14.79 per unit), plus a 15% premium.

In connection with the PA Mining acquisition, in September 2016, the General Partner and CNXC entered into the First Amended and Restated Omnibus Agreement (the "Amended Omnibus Agreement") with CONSOL Energy and certain of its subsidiaries. Under the Amended Omnibus Agreement, CONSOL Energy indemnified CNXC for certain liabilities. The Amended Omnibus Agreement also amended CNXC's obligations to CONSOL Energy with respect to the payment of an annual administrative support fee and reimbursement for the provisions of certain management and operating services provided, in each case to reflect structural changes in how those services are provided to CNXC by CONSOL Energy.

Charges for services from CONSOL Energy include the following:

______________

* Proven and probable coal reserves are the equivalent of “demonstrated reserves” under the coal resource classification system of the U.S. Geological Survey. Generally, these reserves would be commercially mineable at year-end prices and cost levels, using current technology and mining practices.

(1) 143.3 Million tons for the Mason Dixon Project are controlled by CCC, a former subsidiary of CONSOL Energy that was sold in December 2013. As of filing, these tons are still controlled by CCC but are shown in CONSOL Energy's reserves due to a binding agreement that these tons will be released to CONSOL Energy upon consent of the lessor.

CONSOL Energy's coal reserves are located in nearly every major coal-producing region in North America. Our estimate of proven and probable coal reserves has been determined by CONSOL Energy. At December 31, 2016, 141 million tons were assigned to mines either in production or temporarily idled. The proven and probable coal reserves at December 31, 2016 include 2,274 million tons of thermal coal reserves, of which approximately 2 percent has a sulfur content equivalent to less than 1.2 pounds sulfur dioxide per million British thermal unit (Btu), 8 percent has a sulfur content equivalent to between 1.2 and 2.5 pounds sulfur dioxide per million Btu, and 90 percent has a sulfur content equivalent to greater than 2.5 pounds sulfur dioxide per million Btu. The reserves also include 87 million tons of metallurgical coal in consolidated reserves, of which approximately 24 percent has a sulfur content equivalent to less than 1.2 pounds sulfur dioxide per million Btu and 76 percent has a sulfur content equivalent to between 1.2 and 2.5 pounds sulfur dioxide per million Btu.

During the years ended December 31, 2016, 2015 and 2014, we drilled 36.0, 132.8, and 180.3 net development wells, respectively. There were no net dry development wells in 2016, 2015, or 2014.

During the year ended December 31, 2016, there were no net exploratory wells. During the years ended December 31, 2015 and 2014, we drilled 2.5 and 8.5 net exploratory wells, respectively. There wereno net dry exploratory wells in 2016, 2015, or 2014.

At December 31, 2016, there were 15.0 net development wells and no exploratory wells that have been partially drilled but not turned in-line. Additionally there are 65.5 net developmental wells that are drilled but uncompleted and 3.0 net developmental wells and no net exploratory well that have been completed and are awaiting final tie-in to production.

We are committed to provide 431.4 Bcf of gas under existing sales contracts or agreements over the course of the next four years. We expect to produce sufficient quantities from existing proved developed reserves to satisfy these commitments.

Most of our development wells and proved acreage are located in Virginia, West Virginia and Pennsylvania. Some leases are beyond their primary term, but these leases are extended in accordance with their terms as long as certain drilling commitments or other term commitments are satisfied. The following table sets forth, at December 31, 2016, the number of producing wells, developed acreage and undeveloped acreage:

	Gross	Net(1)
Producing Gas Wells (including gob wells)	17,314	12,846
Producing Oil Wells	189	30
Acreage Position:

Unproved Acreage	4,804,804	3,745,533
Total Acreage	5,389,087	4,316,853

____________

(1) Net acres include acreage attributable to our working interests of the properties. Additional adjustments (either increases or decreases) may be required as we further develop title to and further confirm our rights with respect to our various properties in anticipation of development. We believe that our assumptions and methodology in this regard are reasonable.

Proved Oil and Gas Reserves Quantities:

Annually, the preparation of natural gas reserves estimates are completed in accordance with CONSOL Energy's prescribed internal control procedures, which include verification of input data into a gas reserves forecasting and economic evaluation software, as well as multi-functional management review. The input data verification includes reviews of the price and cost assumptions used in the economic model to determine the reserves. Also, the production volumes are reconciled between the system used to calculate the reserves and other accounting/measurement systems. The technical employee responsible for overseeing the preparation of the reserve estimates is a petroleum engineer with over 10 years of experience in the oil and gas industry. Our 2016 gas reserves results, which are reported in the Supplemental Gas Data year ended December 31, 2016 Form 10-K, were audited by Netherland, Sewell & Associates, Inc. The technical person primarily responsible for overseeing the audit of our reserves is a registered professional engineer in the state of Texas with over 15 years of experience in the oil and gas industry. The gas reserves estimates are as follows:

__________

(a) Proved developed and proved undeveloped gas reserves are defined by SEC Rule 4.10(a) of Regulation S-X. Generally, these reserves would be commercially recovered under current economic conditions, operating methods and government regulations. CONSOL Energy cautions that there are many inherent uncertainties in estimating proved reserve quantities, projecting future production rates and timing of development expenditures. Proved oil and gas reserves are estimated quantities of natural gas which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions and government regulations. Proved developed reserves are reserves expected to be recovered through existing wells, with existing equipment and operating methods.

(b) Revisions for 2014 are primarily due to efficiencies in operations andwell optimization and had the total effect of positive revisions. Additionally, the 2014 revisions include a reclassification of ethane volumes from natural gas to NGLs.

(c) Extensions and Discoveries in 2014 are primarily due to the addition of wells on our Marcellus and Utica Shale acreage. We also included Marcellus Shale wells which are more than one offset location away due to continued use of reliable technology.

(d) The upward revisions in 2015 are attributable to efficiencies in operations and well performance.

(e) Extensions and Discoveries in 2015 are due mainly to the high grading of locations which resulted in the addition of wells on our Marcellus and Utica Shale acreage more than one offset location away with continued use of reliable technology.

(f) The net downward revisions for 2016 are primarily due to changes in plans related to future locations.

(g) Extensions and Discoveries in 2016 are due to the addition of wells on our Marcellus and Utica Shale acreage more than one offset location away with continued use of reliable technology.

(h) Purchases and Sales of Reserves In-Place in 2016 is the result of our fourth quarter realignment of the Marcellus Shale properties as part of dissolving our joint venture with Noble Energy.

(i) Included in our proved developed reserves at December 31, 2016 are producing wells with negative undiscounted cash flows that represent 199.3 Bcfe of natural gas and equivalents which represents 3.2% of our total reserves quantities. These consist primarily of conventional wells and the company includes these wells in our reserves as we continue to produce the properties.

(a) During 2016, various exploration and development drilling and evaluations were completed. Approximately, $58,694 ofcapital was spent in the year ended December 31, 2016 related to undeveloped reserves that were transferred to developed.

(b) Plan and other revisions are due to high grading of locations. These changes along with upward revisions attributable to efficiencies in operations and well performance had the total affect of a positive revision.

(c) Extensions and discoveries are due mainly to the high grading of locations which resulted in the addition of wells on our Marcellus and Utica Shale acreage more than one offset location away with continued use of reliable technology.

(d) Included in proved undeveloped reserves at December 31, 2016 are approximately 215,861 MMcfe of reserves that have been reported for more than five years. These reserves specifically relate to GOB (a rubble zone formed in the cavity created by the extraction of coal) production due to a complex fracture being generated in the overburden strata above the mined seam. Mining operations take a significant amount of time and our GOB forecasts are consistent with the future plans of the Buchanan Mine that was sold in March 2016 to Coronado IV LLC (See Note 2 - Discontinued Operations for more information) with the rights to this gas being retained by the Company. Evidence also exists that supports the continual operation of the mine beyond the current plan, unless there was an extreme circumstance resulting from an external factor. These reasons constitute the specific circumstances that exist to continue recognizing these reserves for CONSOL Energy.

(e) Included in proved undeveloped reserves at December 31, 2016 are 175 gross proved undeveloped locations that generate positive future net revenue but have negative present worth discounted at 10 percent as of December 31, 2016, representing 58.9% of our total proved undeveloped reserves. Additionally, the 1,511.8 Bcfe of natural gas and equivalents attributable to these locations represent approximately 24.2% of our total proved reserves. The Company includes these well sites in its current drilling plans and currently intends to drill these sites as our economic modeling of these well locations generate positive future cash flows.

At December 31, 2016 there were no wells pending the determination of proved reserves.

The following table represents the capitalized exploratory well cost activity as indicated:

	December 31,
	2016		2015		2014
Costs reclassified to wells, equipment and facilities based on the determination of proved reserves	$	40,917	$	17,179	$	27,453
Costs expensed due to determination of dry hole or abandonment of project	$	—	$	—	$	2,041

CONSOL Energy's proved natural gas reserves are located in the United States.

Significant Accounting Policy (Policies)

12 Months Ended

Dec. 31, 2016

Accounting Policies [Abstract]

Consolidation, Policy [Policy Text Block]

Basis of Consolidation:

The Consolidated Financial Statements include the accounts of CONSOL Energy Inc, and its wholly owned and majority-owned and/or controlled subsidiaries, including certain variable interest entities that the Company is required to consolidate pursuant to the Consolidated topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification. The portion of these entities that is not owned by the Company is presented as non-controlling interest. Investments in business entities in which CONSOL Energy does not have control, but has the ability to exercise significant influence over the operating and financial policies, are accounted for under the equity method. All significant intercompany transactions and accounts have been eliminated in consolidation. Investments in oil and natural gas producing entities are accounted for under the proportionate consolidation method.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as various disclosures. Actual results could differ from those estimates. The most significant estimates included in the preparation of the consolidated financial statements are related to other postretirement benefits, coal workers' pneumoconiosis, workers' compensation, salary retirement benefits, stock-based compensation, asset retirement obligations, deferred income tax assets and liabilities, contingencies and the values of coal and natural gas, NGLs, condensate and oil (collectively "natural gas") reserves.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents:

Cash and cash equivalents include cash on hand and on deposit at banking institutions as well as all highly liquid short-term securities with original maturities of three months or less.

Trade and Other Accounts Receivable, Policy [Policy Text Block]

Trade Accounts Receivable:

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. CONSOL Energy reserves for specific accounts receivable when it is probable that all or a part of an outstanding balance will not be collected, such as customer bankruptcies. Collectability is determined based on terms of sale, credit status of customers and various other circumstances. CONSOL Energy regularly reviews collectability and establishes or adjusts the allowance as necessary using the specific identification method. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. Reserves for uncollectable amounts were not material in the periods presented. In addition, there were no material financing receivables with a contractual maturity greater than one year at December 31, 2016 or 2015.

Inventory, Policy [Policy Text Block]

Inventories:

Inventories are stated at the lower of cost or net realizable value. The cost of coal inventories is determined by the first-in, first-out (FIFO) method. Coal inventory costs include labor, supplies, equipment costs, operating overhead, depreciation, depletion, amortization, and other related costs. The cost of supplies inventory is determined by the average cost method and includes operating and maintenance supplies to be used in the Company's E&P and coal operations.

Property, Plant and Equipment, Policy [Policy Text Block]

Property, Plant and Equipment:

CONSOL Energy uses the successful efforts method of accounting for natural gas producing activities. Costs of property acquisitions, successful exploratory, development wells and related support equipment and facilities are capitalized. Periodic valuation provisions for impairment of capitalized costs of unproved mineral interests are expensed. Costs of unsuccessful exploratory wells are expensed when such wells are determined to be non-productive, or if the determination cannot be made after finding sufficient quantities of reserves to continue evaluating the viability of the project. The costs of producing properties and mineral interests are amortized using the units-of-production method. Wells and related equipment and intangible drilling costs are also amortized on a units-of-production method. Units-of-production amortization rates are revised at least once per year, or more frequently if events and circumstances indicate an adjustment is necessary. Such revisions are accounted for prospectively as changes in accounting estimates.

Property, plant and equipment is recorded at cost upon acquisition. Expenditures which extend the useful lives of existing plant and equipment are capitalized. Interest costs applicable to major asset additions are capitalized during the construction period. Costs of additional mine facilities required to maintain production after a mine reaches the production stage, generally referred to as “receding face costs,” are expensed as incurred; however, the costs of additional airshafts and new portals are capitalized. Planned major maintenance costs which do not extend the useful lives of existing plant and equipment are expensed as incurred.

Coal exploration costs are expensed as incurred. Coal exploration costs include those incurred to ascertain existence, location, extent or quality of ore or minerals before beginning the development stage of the mine.

Costs of developing new underground mines and certain underground expansion projects are capitalized. Underground development costs, which are costs incurred to make the mineral physically accessible, include costs to prepare property for shafts, driving main entries for ventilation, haulage, personnel, construction of airshafts, roof protection and other facilities.

Airshafts and capitalized mine development associated with a coal reserve are amortized on a units-of-production basis as the coal is produced so that each ton of coal is assigned a portion of the unamortized costs. The Company employs this method to match costs with the related revenues realized in a particular period. Rates are updated when revisions to coal reserve estimates are made. Coal reserve estimates are reviewed when information becomes available that indicates a reserve change is needed, or at a minimum once per year. Any material effect from changes in estimates is disclosed in the period the change occurs. Amortization of development cost begins when the development phase is complete and the production phase begins. At an underground mine, the end of the development phase and the beginning of the production phase takes place when construction of the mine for economic extraction is substantially complete. Coal extracted during the development phase is incidental to the mine's production capacity and is not considered to shift the mine into the production phase.

Coal reserves are controlled either through fee ownership or by lease. The duration of the leases vary; however, the lease terms are generally extended automatically through the exhaustion of economically recoverable reserves, as long as active mining continues. Coal interests held by lease provide the same rights as fee ownership for mineral extraction and are legally considered real property interests. Depletion of leased coal interests is computed using the units-of-productions method over proven and probable coal reserves. The Company also makes advance payments (advanced mining royalties) to lessors under certain lease agreements that are recoupable against future production, and it makes payments that are generally based upon a specified rate per ton or a percentage of gross realization from the sale of the coal. The Company evaluates its properties periodically for impairment issues or whenever events or circumstances indicate that the carrying amount may not be recoverable.

Gas advance royalties are similar in nature to advance mining royalties and are evaluated periodically, or at a minimum once per year, for impairment issues or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Any revisions are accounted for prospectively as changes in accounting estimates.

Depreciation of plant and equipment is calculated on the straight-line method over their estimated useful lives or lease terms, generally as follows:

	Years
Buildings and improvements	10 to 45
Machinery and equipment	3 to 25
Leasehold improvements	Life of Lease

Costs to obtain coal lands are capitalized based on the cost at acquisition and are amortized using the units-of-production method over all estimated proven and probable coal reserve tons assigned and accessible to the mine. Proven and probable coal reserves are calculated on a clean coal ton equivalent, which excludes non-recoverable coal reserves and anticipated preparation plant processing refuse. Rates are updated when revisions to coal reserve estimates are made. Coal reserve estimates are reviewed when events and circumstances indicate a reserve change is needed, or at a minimum once a year. Amortization of coal interests begins when the coal reserve is produced. At an underground coal mine, a ton is considered produced once it reaches the surface area of the mine. Any material effect from changes in estimates is disclosed in the period the change occurs.

Costs for purchased and internally developed software are expensed until it has been determined that the software will result in probable future economic benefits and management has committed to funding the project. Thereafter, all direct costs of materials and services incurred in developing or obtaining software, including certain payroll and benefit costs of employees associated with the project, are capitalized and amortized using the straight-line method over the estimated useful life which does not exceed seven years.

The following assets are amortized using the units-of-production method. Amounts reflect properties where mining or drilling operations have not yet commenced and therefore, are not being amortized for the years ended December 31, 2016 and 2015, respectively.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment of Long-lived Assets:

Impairment of long-lived assets is recorded when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying value. The carrying value of the assets is then reduced to its estimated fair value which is usually measured based on an estimate of future discounted cash flows. Impairment of equity investments is recorded when indicators of impairment are present and the estimated fair value of the investment is less than the assets' carrying value.

Income Tax, Policy [Policy Text Block]

Income Taxes:

Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in CONSOL Energy's financial statements or tax returns. The provision for income taxes represents income taxes paid or payable for the current year and the change in deferred taxes, excluding the effects of acquisitions during the year. Deferred taxes result from differences between the financial and tax bases of CONSOL Energy's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a deferred tax benefit will not be realized.

CONSOL Energy evaluates all tax positions taken on the state and federal tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that do not meet the more likely than not to be sustained criteria, the Company determines, on a cumulative probability basis, the largest amount of benefit that is more likely than not to be realized upon ultimate settlement. A previously recognized tax position is reversed when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the probable amount that is more likely than not is based on judgment, historical experience and on various other assumptions that the Company believes are reasonable under the circumstances. The results of these estimates, that are not readily apparent from other sources, form the basis for recognizing an uncertain tax position liability. Actual results could differ from those estimates upon subsequent resolution of identified matters.

Pension and Other Postretirement Plans, Nonpension Benefits, Policy [Policy Text Block]

Postretirement Benefits Other Than Pensions:

Postretirement benefit obligations established by the Coal Industry Retiree Health Benefit Act of 1992 (the Coal Act) are treated as a multi-employer plan which requires expense to be recorded for the associated obligations as payments are made. Postretirement benefits other than pensions, except for those established pursuant to the Coal Act, are accounted for in accordance with the Retirement Benefits Compensation and Non-retirement Postemployment Benefits Compensation Topics of the FASB Accounting Standards Codification, which requires employers to accrue the cost of such retirement benefits for the employees' active service periods. Such liabilities are determined on an actuarial basis and CONSOL Energy is primarily self-insured for these benefits.

Postemployment Benefit Plans, Policy [Policy Text Block]

Pneumoconiosis Benefits and Workers' Compensation:

CONSOL Energy is required by federal and state statutes to provide benefits to certain current and former totally disabled employees or their dependents for awards related to coal workers' pneumoconiosis. CONSOL Energy is also required by various state statutes to provide workers' compensation benefits for employees who sustain employment-related physical injuries or some types of occupational disease. Workers' compensation benefits include compensation for their disability, medical costs, and on some occasions, the cost of rehabilitation. CONSOL Energy is primarily self-insured for these benefits. Provisions for estimated benefits are determined on an actuarial basis.

Asset Retirement Obligations, Policy [Policy Text Block]

:

CONSOL Energy accrues for dismantling and removing costs of gas-related facilities, mine closing costs, perpetual water care costs, and surface reclamation using the accounting treatment prescribed by the Asset Retirement and Environmental Obligations Topic of the FASB Accounting Standards Codification. This topic requires the fair value of an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. Accrued costs of dismantling and removing natural gas-related facilities, mine closing costs (including surface reclamation costs) and perpetual care costs are regularly reviewed by management and are revised for changes in future estimated costs and regulatory requirements. The present value of the estimated asset retirement costs is capitalized as part of the carrying amount of the long-lived asset. Amortization of the capitalized asset retirement cost is generally determined on a units-of-production basis. Accretion of the asset retirement obligation is recognized over time and generally will escalate over the life of the producing asset, typically as production declines. Accretion is included in Deprecation, Depletion and Amortization on the Consolidated Statements of Income. Asset retirement obligations primarily relate to the closure of natural gas wells and coal mines, which includes treatment of water and the reclamation of land upon exhaustion of coal and natural gas reserves.

CONSOL Energy accrues for dismantling and removing costs of natural gas related facilities, mine closing costs, perpetual water care costs, and surface reclamation using the accounting treatment prescribed by the Asset Retirement and Environmental Obligations Topic of the FASB Accounting Standards Codification. CONSOL Energy recognizes capitalized asset retirement costs by increasing the carrying amount of related long-lived assets. The obligation for asset retirements is included in Gas Well Closing, Mine Closing and Other Accrued Liabilities on the Consolidated Balance Sheets.

Pension and Other Postretirement Plans, Pensions, Policy [Policy Text Block]

Retirement Plans:

Revenue Recognition, Policy [Policy Text Block]

Revenue Recognition:

Revenues are recognized when title passes to the customers. For natural gas, NGL and oil sales, this occurs at the contractual point of delivery. For domestic coal sales, this generally occurs when coal is loaded at the mine, the preparation facility, or offsite storage locations. For export coal sales, this generally occurs when coal is loaded onto marine vessels at terminal locations. For terminal, land, and research and development, revenue is recognized generally as the service is provided to the customer.

CONSOL Energy has operational natural gas-balancing agreements. These imbalance agreements are managed internally using the sales method of accounting. The sales method recognizes revenue when the gas is taken by the purchaser.

CONSOL Energy sells natural gas to accommodate the delivery points of its customers. In general, this gas is purchased at market price and re-sold on the same day at market price less a small transaction fee. These matching buy/sell transactions include a legal right of offset of obligations and have been simultaneously entered into with the counterparty. These transactions qualify for netting under the Nonmonetary Transactions Topic of the FASB Accounting Standards Codification and are, therefore, recorded net within the Consolidated Statements of Income in the Purchased Gas Sales line.

CONSOL Energy purchases natural gas produced by third-parties at market prices less a fee. The gas purchased from third-parties is then resold to end users or gas marketers at current market prices. These revenues and expenses are recorded gross as Purchased Gas Sales in the Consolidated Statements of Income. Purchased gas sales are recognized when title passes to the customer. Purchased gas costs are recognized when title passes to CONSOL Energy from the third-party.

Revenue Recognition, Cargo and Freight, Policy [Policy Text Block]

Freight Revenue and Expense:

Shipping and handling costs invoiced to coal customers and paid to third-party carriers are recorded as Freight-Outside Coal revenue and Freight Expense, respectively.

Revenue Recognition, Services, Royalty Fees [Policy Text Block]

Commitments and Contingencies, Policy [Policy Text Block]

Contingencies:

From time to time, CONSOL Energy, or its subsidiaries, is subject to various lawsuits and claims with respect to such matters as personal injury, wrongful death, damage to property, exposure to hazardous substances, governmental regulations (including environmental remediation), employment and contract disputes, and other claims and actions, arising out of the normal course of business. Liabilities are recorded when it is probable that obligations have been incurred and the amounts can be reasonably estimated. Estimates are developed through consultation with legal counsel involved in the defense of these matters and are based upon the nature of the lawsuit, progress of the case in court, view of legal counsel, prior experience in similar matters and management's intended response. Environmental liabilities are not discounted or reduced by possible recoveries from third-parties. Legal fees associated with defending these various lawsuits and claims are expensed when incurred.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]

Stock-Based Compensation:

Stock-based compensation expense for all stock-based compensation awards is based on the grant date fair value estimated in accordance with the provisions of the Stock Compensation Topic of the FASB Accounting Standards Codification. CONSOL Energy recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is generally the award's vesting term. See Note 17–Stock-Based Compensation for

Earnings Per Share, Policy [Policy Text Block]

Earnings per Share:

Basic earnings per share are computed by dividing net income attributable to CONSOL Energy Shareholders by the weighted average shares outstanding during the reporting period. Dilutive earnings per share are computed similarly to basic earnings per share, except that the weighted average shares outstanding are increased to include additional shares from stock options, performance stock options, restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding stock options and performance share options were exercised, that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities were used to acquire shares of common stock at the average market price during the reporting period. CONSOL Energy includes the impact of pro forma deferred tax assets in determining potential windfalls and shortfalls for purposes of calculating assumed proceeds under the treasury stock method.

The table below sets forth the share-based awards that have been excluded from the computation of the diluted earnings per share because their effect would be anti-dilutive:

Significant Accounting Policies [Text Block]

SIGNIFICANT ACCOUNTING POLICIES:

A summary of the significant accounting policies of CONSOL Energy Inc. and subsidiaries ("CONSOL Energy" or "the Company") is presented below. These, together with the other notes that follow, are an integral part of the Consolidated Financial Statements.

Basis of Consolidation:

The Consolidated Financial Statements include the accounts of CONSOL Energy Inc, and its wholly owned and majority-owned and/or controlled subsidiaries, including certain variable interest entities that the Company is required to consolidate pursuant to the Consolidated topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification. The portion of these entities that is not owned by the Company is presented as non-controlling interest. Investments in business entities in which CONSOL Energy does not have control, but has the ability to exercise significant influence over the operating and financial policies, are accounted for under the equity method. All significant intercompany transactions and accounts have been eliminated in consolidation. Investments in oil and natural gas producing entities are accounted for under the proportionate consolidation method.

Discontinued Operations:

Businesses divested are classified in the Consolidated Financial Statements as either discontinued operations or held for sale when the provision of Accounting Standards Codification (ASC) Topic 205 or ASC Topic 360 are met. For businesses classified as discontinued operations, the balance sheet amounts and results of operations are reclassified from their historical presentation to assets and liabilities of discontinued operations on the Consolidated Balance Sheets and to discontinued operations on the Consolidated Statements of Income and Cash Flows for all periods presented. The gains or losses associated with these divested businesses are recorded in discontinued operations on the Consolidated Statements of Income. The disclosures outside of Note 2- Discontinued Operations, for all periods presented, in the accompanying notes generally do not include the assets, liabilities, or operating results of businesses classified as discontinued operations.

Use of Estimates:

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as well as various disclosures. Actual results could differ from those estimates. The most significant estimates included in the preparation of the consolidated financial statements are related to other postretirement benefits, coal workers' pneumoconiosis, workers' compensation, salary retirement benefits, stock-based compensation, asset retirement obligations, deferred income tax assets and liabilities, contingencies and the values of coal and natural gas, NGLs, condensate and oil (collectively "natural gas") reserves.

Cash and Cash Equivalents:

Cash and cash equivalents include cash on hand and on deposit at banking institutions as well as all highly liquid short-term securities with original maturities of three months or less.

Trade Accounts Receivable:

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. CONSOL Energy reserves for specific accounts receivable when it is probable that all or a part of an outstanding balance will not be collected, such as customer bankruptcies. Collectability is determined based on terms of sale, credit status of customers and various other circumstances.

Proven and probable coal reserves are calculated on a clean coal ton equivalent, which excludes non-recoverable coal reserves and anticipated preparation plant processing refuse. Rates are updated when revisions to coal reserve estimates are made. Coal reserve estimates are reviewed when events and circumstances indicate a reserve change is needed, or at a minimum once a year. Amortization of coal interests begins when the coal reserve is produced. At an underground coal mine, a ton is considered produced once it reaches the surface area of the mine. Any material effect from changes in estimates is disclosed in the period the change occurs.

Costs for purchased and internally developed software are expensed until it has been determined that the software will result in probable future economic benefits and management has committed to funding the project. Thereafter, all direct costs of materials and services incurred in developing or obtaining software, including certain payroll and benefit costs of employees associated with the project, are capitalized and amortized using the straight-line method over the estimated useful life which does not exceed seven years.

Capitalization of Interest:

Interest costs associated with the development of significant properties and projects are capitalized until the project is substantially complete and ready for its intended use. A weighted average cost of borrowing rate is used. For the years ended December 31, 2016, 2015, and 2014, capitalized interest totaled $1,467, $2,509 and $13,573, respectively.

Impairment of Long-lived Assets:

Impairment of long-lived assets is recorded when indicators of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets' carrying value. The carrying value of the assets is then reduced to its estimated fair value which is usually measured based on an estimate of future discounted cash flows. Impairment of equity investments is recorded when indicators of impairment are present and the estimated fair value of the investment is less than the assets' carrying value.

Impairment of Proved Properties

CONSOL Energy performs a quantitative annual impairment test, during the fourth quarter of each year, over proved properties using the published NYMEX forward prices, timing, methods and other assumptions consistent with historical periods. During interim periods, management updates these annual tests whenever events or changes in circumstances indicate that a property’s carrying amount may not be recoverable. Impairment tests require that the Company first compare future undiscounted cash flows by asset group to their respective carrying values. If the carrying amount exceeds the estimated undiscounted future cash flows, a reduction of the carrying amount of the natural gas properties to their estimated fair values is required, which is determined based on discounted cash flow techniques using a market-specific weighted average cost of capital. 

During the year ended December 31, 2015, certain of the Company’s proved properties, primarily shallow oil and gas assets, failed the undiscounted cash flow portion of the test. After performing the discounted cash flow portion of the test, CONSOL Energy recorded an impairment of $824,742, included in Impairment of Exploration and Production Properties in the Consolidated Statements of Income. Valuation of the impaired assets is a Level 3 measurement as it incorporates significant unobservable inputs, such as future production levels and operating costs, within the discounted cash flow analysis. The impairment related to approximately 95% of the Company’s shallow oil and gas assets in West Virginia and Pennsylvania.

There were no other additional impairments related to proved properties in the year ended December 31, 2015. There were no such impairments for the years ended December 31, 2016 or 2014.

Impairment of Unproved Properties

CONSOL Energy evaluates capitalized costs of unproved gas properties for recoverability on a prospective basis. Indicators of potential impairment include potential shifts in business strategy, overall economic factors and historical experience. If it is determined that the properties will not yield proved reserves, the related costs are expensed in the period the determination is made. For the year ended December 31, 2015, unproved property impairments relating to the determination that the properties will not yield proved reserves were $4,163 and are included in Impairment of Exploration and Production Properties in the Consolidated Statements of Income. Valuation of the impaired assets is a Level 3 measurement as it incorporates significant unobservable inputs, such as future production levels and operating costs, within the discounted cash flow analysis. This impairment primarily related to the court ruling in June 2015 in the state of New York that officially bans hydraulic fracturing.

There were no other additional impairments related to unproved properties in the year ended December 31, 2015. There were no such impairments for the years ended December 31, 2016 and 2014.

Exploration expense, which is associated primarily with lease expirations, was $14,519, $10,120 and $23,355 for the years ended December 31, 2016, 2015 and 2014, respectively, and is included in Exploration and Production Related Other Costs in the Consolidated Statements of Income.

Income Taxes:

Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been recognized in CONSOL Energy's financial statements or tax returns. The provision for income taxes represents income taxes paid or payable for the current year and the change in deferred taxes, excluding the effects of acquisitions during the year. Deferred taxes result from differences between the financial and tax bases of CONSOL Energy's assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when it is more likely than not that a deferred tax benefit will not be realized.

CONSOL Energy evaluates all tax positions taken on the state and federal tax filings to determine if the position is more likely than not to be sustained upon examination. For positions that do not meet the more likely than not to be sustained criteria, the Company determines, on a cumulative probability basis, the largest amount of benefit that is more likely than not to be realized upon ultimate settlement. A previously recognized tax position is reversed when it is subsequently determined that a tax position no longer meets the more likely than not threshold to be sustained. The evaluation of the sustainability of a tax position and the probable amount that is more likely than not is based on judgment, historical experience and on various other assumptions that the Company believes are reasonable under the circumstances. The results of these estimates, that are not readily apparent from other sources, form the basis for recognizing an uncertain tax position liability. Actual results could differ from those estimates upon subsequent resolution of identified matters.

Postretirement Benefits Other Than Pensions:

Postretirement benefit obligations established by the Coal Industry Retiree Health Benefit Act of 1992 (the Coal Act) are treated as a multi-employer plan which requires expense to be recorded for the associated obligations as payments are made. Postretirement benefits other than pensions, except for those established pursuant to the Coal Act, are accounted for in accordance with the Retirement Benefits Compensation and Non-retirement Postemployment Benefits Compensation Topics of the FASB Accounting Standards Codification, which requires employers to accrue the cost of such retirement benefits for the employees' active service periods. Such liabilities are determined on an actuarial basis and CONSOL Energy is primarily self-insured for these benefits. Differences between actual and expected results or changes in the value of obligations are recognized through Other Comprehensive Income.

Pneumoconiosis Benefits and Workers' Compensation:

CONSOL Energy is required by federal and state statutes to provide benefits to certain current and former totally disabled employees or their dependents for awards related to coal workers' pneumoconiosis. CONSOL Energy is also required by various state statutes to provide workers' compensation benefits for employees who sustain employment-related physical injuries or some types of occupational disease. Workers' compensation benefits include compensation for their disability, medical costs, and on some occasions, the cost of rehabilitation. CONSOL Energy is primarily self-insured for these benefits. Provisions for estimated benefits are determined on an actuarial basis.

Gas Well Closing and Mine Closing Costs:

CONSOL Energy accrues for dismantling and removing costs of gas-related facilities, mine closing costs, perpetual water care costs, and surface reclamation using the accounting treatment prescribed by the Asset Retirement and Environmental Obligations Topic of the FASB Accounting Standards Codification. This topic requires the fair value of an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. Accrued costs of dismantling and removing natural gas-related facilities, mine closing costs (including surface reclamation costs) and perpetual care costs are regularly reviewed by management and are revised for changes in future estimated costs and regulatory requirements. The present value of the estimated asset retirement costs is capitalized as part of the carrying amount of the long-lived asset. Amortization of the capitalized asset retirement cost is generally determined on a units-of-production basis. Accretion of the asset retirement obligation is recognized over time and generally will escalate over the life of the producing asset, typically as production declines. Accretion is included in Deprecation, Depletion and Amortization on the Consolidated Statements of Income. Asset retirement obligations primarily relate to the closure of natural gas wells and coal mines, which includes treatment of water and the reclamation of land upon exhaustion of coal and natural gas reserves.

Subsidence:

Subsidence occurs when there is sinking or shifting of the ground surface due to the removal of underlying coal. Areas affected may include, although are not limited to, streams, property, roads, pipelines and other land and surface structures. Total estimated subsidence claims are recognized in the period when the related coal has been extracted and are included in Operating and Other Costs on the Consolidated Statements of Income and Other Accrued Liabilities on the Consolidated Balance Sheets. On occasion, CONSOL Energy prepays the estimated damages prior to undermining the property, in return for a release of liability. Prepayments are included as assets and either recognized as Prepaid Expenses or in Other Assets on the Consolidated Balance Sheets if the payment is made less than or greater than one year, respectively, prior to undermining the property.

Retirement Plans:

CONSOL Energy has non-contributory defined benefit retirement plans. Effective December 31, 2015, CONSOL's qualified defined benefit retirement plans have been frozen. The benefits for these plans are based primarily on years of service and employees' pay. These plans are accounted for using the guidance outlined in the Compensation - Retirement Benefits Topic of the FASB Accounting Standards Codification. The cost of these retiree benefits are recognized over the employees' service periods. CONSOL Energy uses actuarial methods and assumptions in the valuation of defined benefit obligations and the determination of expense. Differences between actual and expected results or changes in the value of obligations and plan assets are recognized through Other Comprehensive Income.

Revenue Recognition:

Revenues are recognized when title passes to the customers. For natural gas, NGL and oil sales, this occurs at the contractual point of delivery. For domestic coal sales, this generally occurs when coal is loaded at the mine, the preparation facility, or offsite storage locations. For export coal sales, this generally occurs when coal is loaded onto marine vessels at terminal locations. For terminal, land, and research and development, revenue is recognized generally as the service is provided to the customer.

CONSOL Energy has operational natural gas-balancing agreements. These imbalance agreements are managed internally using the sales method of accounting. The sales method recognizes revenue when the gas is taken by the purchaser.

CONSOL Energy sells natural gas to accommodate the delivery points of its customers. In general, this gas is purchased at market price and re-sold on the same day at market price less a small transaction fee. These matching buy/sell transactions include a legal right of offset of obligations and have been simultaneously entered into with the counterparty. These transactions qualify for netting under the Nonmonetary Transactions Topic of the FASB Accounting Standards Codification and are, therefore, recorded net within the Consolidated Statements of Income in the Purchased Gas Sales line.

CONSOL Energy purchases natural gas produced by third-parties at market prices less a fee. The gas purchased from third-parties is then resold to end users or gas marketers at current market prices. These revenues and expenses are recorded gross as Purchased Gas Sales in the Consolidated Statements of Income. Purchased gas sales are recognized when title passes to the customer. Purchased gas costs are recognized when title passes to CONSOL Energy from the third-party.

Freight Revenue and Expense:

Shipping and handling costs invoiced to coal customers and paid to third-party carriers are recorded as Freight-Outside Coal revenue and Freight Expense, respectively.

Contingencies:

From time to time, CONSOL Energy, or its subsidiaries, is subject to various lawsuits and claims with respect to such matters as personal injury, wrongful death, damage to property, exposure to hazardous substances, governmental regulations (including environmental remediation), employment and contract disputes, and other claims and actions, arising out of the normal course of business. Liabilities are recorded when it is probable that obligations have been incurred and the amounts can be reasonably estimated. Estimates are developed through consultation with legal counsel involved in the defense of these matters and are based upon the nature of the lawsuit, progress of the case in court, view of legal counsel, prior experience in similar matters and management's intended response. Environmental liabilities are not discounted or reduced by possible recoveries from third-parties. Legal fees associated with defending these various lawsuits and claims are expensed when incurred.

Stock-Based Compensation:

Stock-based compensation expense for all stock-based compensation awards is based on the grant date fair value estimated in accordance with the provisions of the Stock Compensation Topic of the FASB Accounting Standards Codification. CONSOL Energy recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is generally the award's vesting term. See Note 17–Stock-Based Compensation for more information.

Earnings per Share:

Basic earnings per share are computed by dividing net income attributable to CONSOL Energy Shareholders by the weighted average shares outstanding during the reporting period. Dilutive earnings per share are computed similarly to basic earnings per share, except that the weighted average shares outstanding are increased to include additional shares from stock options, performance stock options, restricted stock units and performance share units, if dilutive. The number of additional shares is calculated by assuming that outstanding stock options and performance share options were exercised, that outstanding restricted stock units and performance share units were released, and that the proceeds from such activities were used to acquire shares of common stock at the average market price during the reporting period. CONSOL Energy includes the impact of pro forma deferred tax assets in determining potential windfalls and shortfalls for purposes of calculating assumed proceeds under the treasury stock method.

The table below sets forth the share-based awards that have been excluded from the computation of the diluted earnings per share because their effect would be anti-dilutive:

Accounting for Derivative Instruments:

CONSOL Energy enters into financial derivative instruments to manage its exposure to commodity price volatility. The derivatives are accounted for as an asset or a liability in the accompanying Consolidated Balance Sheets at their fair value using “Level Two” inputs, which is further defined in Note 20 - Fair Value of Financial Instruments. Changes in the fair values of derivatives are recorded in earnings unless special hedge accounting criteria are met. For derivatives designated as cash flow hedges, the effective portions of changes in the fair values of the derivatives are reported in Other Comprehensive Income or Loss (OCI) on the Consolidated Balance Sheets, net of tax, and reclassified into Gain (Loss) on Commodity Derivative Instruments on the Consolidated Statements of Income in the same period or periods in which the forecasted transactions affect earnings. Any ineffective portion of a hedge is recognized in earnings in the current period.     

CONSOL Energy de-designated all of its cash flow hedges on December 31, 2014 and accounts for all existing and future natural gas and NGL commodity hedges on a mark-to-market basis, and records changes in fair value in current period earnings. In connection with this de-designation, CONSOL Energy froze the balances recorded in Accumulated Other Comprehensive Income at December 31, 2014 and reclassified balances to earnings as the underlying physical transactions occurred. As of December 31, 2016, all gains deferred in OCI have been recognized in earnings.

All of CONSOL Energy’s derivative instruments are subject to master netting arrangements with its counterparties, none of which currently require CONSOL Energy to post collateral for any of its hedges. However, as stated in the counterparty master agreements, if CONSOL Energy's obligations with one of its counterparties cease to be secured on the same basis as similar obligations with the other lenders under the credit facility, CONSOL Energy would be required to post collateral for hedges that are in a liability position in excess of defined thresholds. Each of CONSOL Energy's counterparty master agreements allows, in the event of default, the ability to elect early termination of outstanding contracts. If early termination is elected, CONSOL Energy and the applicable counterparty would net settle all open hedge positions.

CONSOL Energy is exposed to credit risk in the event of non-performance by counterparties, whose creditworthiness is subject to continuing review. Historically, CONSOL Energy has not experienced any issues of non-performance by derivative counterparties.

Recent Accounting Pronouncements:

In January 2017, the FASB issued Update 2017-01 - Business Combinations (Topic 805). This update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of this new guidance is not expected to have a material impact on CONSOL Energy's financial statements.

In December 2016, the FASB issued Update 2016-19 - Technical Corrections and Improvements, which covers a wide range of Topics in the Accounting Standards Codification (ASC). The amendments in this Update represent changes to clarify, correct errors, or make minor improvements to the ASC, making it easier to understand and apply by eliminating inconsistencies and providing clarifications. The amendments generally fall into one of the following categories: amendments related to differences between original guidance and the ASC, guidance clarification and reference corrections, simplification, or minor improvements. Most of the amendments in this Update do not require transition guidance and are effective upon issuance of this Update.

In October 2016, the FASB issued Update 2016-17 - Consolidation (Topic 810): Interests Held through Related Parties that are Under Common Control, which amends the consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity (VIE) should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The Update requires the reporting entity, in determining whether it satisfies the second characteristic of a primary beneficiary, to include its indirect economic interests in a VIE held through related parties that are under common control on a proportionate basis as opposed to in their entirety. The amendments in this Update will be applied retrospectively and are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The adoption of this new guidance is not expected to have a material impact on CONSOL Energy's financial statements.

In August 2016, the FASB issued Update 2016-15 - Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments relate to debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, distributions received from equity method investees, and beneficial interests in securitization transactions. The Update also states that, in the absence of specific guidance for cash receipts and payments that have aspects of more than one class of cash flows, an entity should classify each separately identifiable source or use within the cash receipts and payments on the basis of their nature in financing, investing, or operating activities. In situations in which cash receipts or payments cannot be separated by source or use, the appropriate classification should depend on the activity that is likely to be the predominant source or use of cash flows for the item. The amendments in the Update will be applied using a retrospective transition method to each period presented and, for public entities, are effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact this guidance may have on CONSOL Energy's financial statements.

In June 2016, the FASB issued Update 2016-13 - Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which provides financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this, the amendments in this Update replace the incurred loss impairment methodology in current Generally Accepted Accounting Principals (GAAP) with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The measurement of expected credit losses will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectibility of the reported amount. The amendments in this Update will be applied using a modified-retrospective approach and, for public entities, are effective for fiscal years beginning after December 15, 2019 and interim periods within those annual periods. Early adoption is permitted for fiscal years beginning after December 15, 2018 and interim periods within those annual periods. The Company believes this guidance will not have a material impact on CONSOL Energy's financial statements.

In May 2014, the FASB issued Update 2014-09 - Revenue from Contracts with Customers (Topic 606), which supersedes the revenue recognition requirements in Topic 605 - Revenue Recognition and most industry-specific guidance throughout the Industry Topics of the Codification. The objective of the amendments in this Update is to improve financial reporting by creating common revenue recognition guidance for U.S. GAAP and International Financial Reporting Standards (IFRS). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services and should disclose sufficient information, both qualitative and quantitative, to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The following updates to Topic 606 were made during 2016:

• In March 2016, the FASB issued Update 2016-08 - Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies how an entity determines whether it is a principal or an agent for goods or services promised to a customer as well as the nature of the goods or services promised to their customers.

• In April 2016, the FASB issued Update 2016-10 - Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing, which seeks to address implementation issues in the areas of identifying performance obligations and licensing.

• In May 2016, the FASB issued Update 2016-12 - Revenue from Contracts with Customers: Narrow Scope Improvements and Practical Expedients, which seeks to address implementation issues in the areas of collectibility, presentation of sales taxes, noncash consideration, and completed contracts and contract modifications at transition.

• In December 2016, the FASB issued Update 2016-20 - Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers, which includes amendments related to loan guarantee fees, contract costs, provisions for losses on construction and production-type contracts, scope, disclosures, contract modification, contract asset versus receivable, refund liability and advertising costs.

The new standards are effective for annual reporting periods beginning after December 15, 2017, with the option to adopt as early as annual reporting periods beginning after December 15, 2016. Management continues to evaluate the impacts that these standards will have on CONSOL Energy's financial statements, specifically as it relates to contracts that contain positive electric power price related adjustments. CONSOL Energy anticipates using the modified retrospective approach at adoption as it relates to ASU 2014-09.

In March 2016, the FASB issued Update 2016-09 - Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Specifically, this Update states that: all excess tax benefits and tax deficiencies should be recognized as income tax expense or benefit in the income statement; excess tax benefits should be classified along with other income tax cash flows as an operating activity; an entity can make an accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur; the threshold to qualify for equity classification permits withholding up to the maximum statutory tax rates in the applicable jurisdictions; and cash paid by an employer when directly withholding shares for tax-withholding purposes should be classified as a financing activity. For public entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2016 and interim periods within those annual periods. Early adoption is permitted. The adoption of this new guidance is not expected to have a material impact on CONSOL Energy's financial statements.

In February 2016, the FASB issued Update 2016-02 - Leases (Topic 842), which increases transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Update 2016-02 does retain a distinction between finance leases and operating leases, which is substantially similar to the classification criteria for distinguishing between capital leases and operating leases in the previous lease guidance. Retaining this distinction allows the recognition, measurement and presentation of expenses and cash flows arising from a lease to not significantly change from previous GAAP. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities, but to recognize lease expense on a straight-line basis over the lease term. For both financing and operating leases, the right-to-use asset and lease liability will be initially measured at the present value of the lease payments in the statement of financial position.The accounting applied by a lessor is largely unchanged from that applied under previous GAAP. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application is permitted. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company is currently evaluating the impact this guidance may have on CONSOL Energy's financial statements.

Reclassifications:

During the year ended December 31, 2016, CONSOL Energy made reclassifications within its financial statements to better align the Company's financial reporting with its peer group. These reclassifications impacted the Lease Operating Expense, Transportation, Gathering and Compression, Direct Administrative and Selling, Production Royalty Interests and Purchased Gas Sales, Production Royalty Interests and Purchased Gas Costs, Operating and Other Costs and Selling, General and Administrative Costs line items on the Company's Consolidated Statements of Income. These changes are reflected in CONSOL Energy's current and historic Consolidated Statements of Income, with no effect on previously reported net income (loss).

Subsequent Events:

The Company has evaluated all subsequent events through the date the financial statements were issued. No material recognized or non-recognizable subsequent events were identified.

Asset Retirement Obligation Disclosure [Text Block]

NOTE 7—GAS WELL CLOSING and MINE CLOSING:

CONSOL Energy accrues for dismantling and removing costs of natural gas related facilities, mine closing costs, perpetual water care costs, and surface reclamation using the accounting treatment prescribed by the Asset Retirement and Environmental Obligations Topic of the FASB Accounting Standards Codification. CONSOL Energy recognizes capitalized asset retirement costs by increasing the carrying amount of related long-lived assets. The obligation for asset retirements is included in Gas Well Closing, Mine Closing and Other Accrued Liabilities on the Consolidated Balance Sheets.

The reconciliation of changes in the asset retirement obligations at December 31, 2016 and 2015 is as follows:

	As of December 31,
	2016			2015
Balance at beginning of period	$	429,967		$	454,832
Accretion expense	23,924			32,438

Asset Retirement Obligations, Policy [Policy Text Block]

:

CONSOL Energy accrues for dismantling and removing costs of gas-related facilities, mine closing costs, perpetual water care costs, and surface reclamation using the accounting treatment prescribed by the Asset Retirement and Environmental Obligations Topic of the FASB Accounting Standards Codification. This topic requires the fair value of an asset retirement obligation be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. Accrued costs of dismantling and removing natural gas-related facilities, mine closing costs (including surface reclamation costs) and perpetual care costs are regularly reviewed by management and are revised for changes in future estimated costs and regulatory requirements. The present value of the estimated asset retirement costs is capitalized as part of the carrying amount of the long-lived asset. Amortization of the capitalized asset retirement cost is generally determined on a units-of-production basis. Accretion of the asset retirement obligation is recognized over time and generally will escalate over the life of the producing asset, typically as production declines. Accretion is included in Deprecation, Depletion and Amortization on the Consolidated Statements of Income. Asset retirement obligations primarily relate to the closure of natural gas wells and coal mines, which includes treatment of water and the reclamation of land upon exhaustion of coal and natural gas reserves.

Property, Plant and Equipment PP&E Accounting Policy (Policies)

12 Months Ended

Dec. 31, 2016

Property, Plant and Equipment [Abstract]

Property, Plant and Equipment, Policy [Policy Text Block]

Property, Plant and Equipment:

CONSOL Energy uses the successful efforts method of accounting for natural gas producing activities. Costs of property acquisitions, successful exploratory, development wells and related support equipment and facilities are capitalized. Periodic valuation provisions for impairment of capitalized costs of unproved mineral interests are expensed. Costs of unsuccessful exploratory wells are expensed when such wells are determined to be non-productive, or if the determination cannot be made after finding sufficient quantities of reserves to continue evaluating the viability of the project. The costs of producing properties and mineral interests are amortized using the units-of-production method. Wells and related equipment and intangible drilling costs are also amortized on a units-of-production method. Units-of-production amortization rates are revised at least once per year, or more frequently if events and circumstances indicate an adjustment is necessary. Such revisions are accounted for prospectively as changes in accounting estimates.

Property, plant and equipment is recorded at cost upon acquisition. Expenditures which extend the useful lives of existing plant and equipment are capitalized. Interest costs applicable to major asset additions are capitalized during the construction period. Costs of additional mine facilities required to maintain production after a mine reaches the production stage, generally referred to as “receding face costs,” are expensed as incurred; however, the costs of additional airshafts and new portals are capitalized. Planned major maintenance costs which do not extend the useful lives of existing plant and equipment are expensed as incurred.

Coal exploration costs are expensed as incurred. Coal exploration costs include those incurred to ascertain existence, location, extent or quality of ore or minerals before beginning the development stage of the mine.

Costs of developing new underground mines and certain underground expansion projects are capitalized. Underground development costs, which are costs incurred to make the mineral physically accessible, include costs to prepare property for shafts, driving main entries for ventilation, haulage, personnel, construction of airshafts, roof protection and other facilities.

Airshafts and capitalized mine development associated with a coal reserve are amortized on a units-of-production basis as the coal is produced so that each ton of coal is assigned a portion of the unamortized costs. The Company employs this method to match costs with the related revenues realized in a particular period. Rates are updated when revisions to coal reserve estimates are made. Coal reserve estimates are reviewed when information becomes available that indicates a reserve change is needed, or at a minimum once per year. Any material effect from changes in estimates is disclosed in the period the change occurs. Amortization of development cost begins when the development phase is complete and the production phase begins. At an underground mine, the end of the development phase and the beginning of the production phase takes place when construction of the mine for economic extraction is substantially complete. Coal extracted during the development phase is incidental to the mine's production capacity and is not considered to shift the mine into the production phase.

Coal reserves are controlled either through fee ownership or by lease. The duration of the leases vary; however, the lease terms are generally extended automatically through the exhaustion of economically recoverable reserves, as long as active mining continues. Coal interests held by lease provide the same rights as fee ownership for mineral extraction and are legally considered real property interests. Depletion of leased coal interests is computed using the units-of-productions method over proven and probable coal reserves. The Company also makes advance payments (advanced mining royalties) to lessors under certain lease agreements that are recoupable against future production, and it makes payments that are generally based upon a specified rate per ton or a percentage of gross realization from the sale of the coal. The Company evaluates its properties periodically for impairment issues or whenever events or circumstances indicate that the carrying amount may not be recoverable.

Gas advance royalties are similar in nature to advance mining royalties and are evaluated periodically, or at a minimum once per year, for impairment issues or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Any revisions are accounted for prospectively as changes in accounting estimates.

Depreciation of plant and equipment is calculated on the straight-line method over their estimated useful lives or lease terms, generally as follows:

	Years
Buildings and improvements	10 to 45
Machinery and equipment	3 to 25
Leasehold improvements	Life of Lease

Costs to obtain coal lands are capitalized based on the cost at acquisition and are amortized using the units-of-production method over all estimated proven and probable coal reserve tons assigned and accessible to the mine. Proven and probable coal reserves are calculated on a clean coal ton equivalent, which excludes non-recoverable coal reserves and anticipated preparation plant processing refuse. Rates are updated when revisions to coal reserve estimates are made. Coal reserve estimates are reviewed when events and circumstances indicate a reserve change is needed, or at a minimum once a year. Amortization of coal interests begins when the coal reserve is produced. At an underground coal mine, a ton is considered produced once it reaches the surface area of the mine. Any material effect from changes in estimates is disclosed in the period the change occurs.

Costs for purchased and internally developed software are expensed until it has been determined that the software will result in probable future economic benefits and management has committed to funding the project. Thereafter, all direct costs of materials and services incurred in developing or obtaining software, including certain payroll and benefit costs of employees associated with the project, are capitalized and amortized using the straight-line method over the estimated useful life which does not exceed seven years.

The following assets are amortized using the units-of-production method. Amounts reflect properties where mining or drilling operations have not yet commenced and therefore, are not being amortized for the years ended December 31, 2016 and 2015, respectively.

	For the Year Ended				For the Year Ended
	December 31,				December 31,
	2016		2015		2016		2015
Discount rate	4.31	%	4.50	%	4.22	%	4.50	%
Rate of compensation increase	3.90	%	3.80	%	—		—

The discount rates are determined using a Company-specific yield curve model (above-mean) developed with the assistance of an external actuary. The Company-specific yield curve models (above-mean) use a subset of the expanded bond universe to determine the Company-specific discount rate. Bonds used in the yield curve are rated AA by Moody's or Standard & Poor's as of the measurement date. The yield curve models parallel the plans' projected cash flows, and the underlying cash flows of the bonds included in the models exceed the cash flows needed to satisfy the Company plans.

The weighted-average assumptions used to determine net periodic benefit costs are as follows:

	Pension Benefits at						Other Postretirement Benefits at

SUPPLEMENTAL GAS DATA: [Abstract]

Standardized Measure of Discounted Future Cash Flows Relating to Proved Reserves Disclosure [Table Text Block]

The standardized measure is intended to provide a better means for comparing the value of CONSOL Energy's proved reserves at a given time with those of other gas producing companies than is provided by a comparison of raw proved reserve quantities.

	December 31,
	2016			2015			2014

Total standardized measure of discounted net cash flows	$	955,117		$	1,019,304		$	2,984,158

(a) For 2016, the reserves were computed using unweighted arithmetic averages of the closing prices on the first day of each month during 2016, adjusted for energy content and a regional price differential. For 2016, this adjusted natural gas price was $1.73 per mcf, the adjusted oil price was $25.04 per barrel and the adjusted NGL price was $15.77 per barrel.

For 2015, the reserves were computed using unweighted arithmetic averages of the closing prices on the first day of each month during 2015, adjusted for energy content and a regional price differential. For 2015, this adjusted natural gas price was $2.02 per mcf, the adjusted oil price was $25.29 per barrel and the adjusted NGL price was $15.59 per barrel.

For 2014, the reserves were computed using unweighted arithmetic averages of the closing prices on the first day of each month during 2014, adjusted for energy content and a regional price differential. For 2014, this adjusted natural gas price was $3.85 per mcf, the adjusted oil price was $77.30 per barrel and the adjusted NGL price was $46.54 per barrel.

Schedule of Gas and Oil Acreage [Table Text Block]

Most of our development wells and proved acreage are located in Virginia, West Virginia and Pennsylvania. Some leases are beyond their primary term, but these leases are extended in accordance with their terms as long as certain drilling commitments or other term commitments are satisfied. The following table sets forth, at December 31, 2016, the number of producing wells, developed acreage and undeveloped acreage:

	Gross	Net(1)
Producing Gas Wells (including gob wells)	17,314	12,846
Producing Oil Wells	189	30
Acreage Position:
Proved Developed Acreage	549,816	541,282

Unproved Acreage	4,804,804	3,745,533
Total Acreage	5,389,087	4,316,853

____________

(1) Net acres include acreage attributable to our working interests of the properties. Additional adjustments (either increases or decreases) may be required as we further develop title to and further confirm our rights with respect to our various properties in anticipation of development. We believe that our assumptions and methodology in this regard are reasonable.
