CARRIZO OIL & GAS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation

Nature of Operations

Carrizo Oil & Gas, Inc. is a Houston-based energy company which, together with its subsidiaries (collectively, the “Company”), is actively engaged in the exploration, development, and production of oil and gas primarily from resource plays located in the United States. The Company’s current operations are principally focused in proven, producing oil and gas plays primarily in the Eagle Ford Shale in South Texas, the Delaware Basin in West Texas, the Niobrara Formation in Colorado, the Utica Shale in Ohio, and the Marcellus Shale in Pennsylvania.

Consolidated Financial Statements

The accompanying unaudited interim consolidated financial statements include the accounts of the Company after elimination of intercompany transactions and balances and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and therefore do not include all disclosures required for financial statements prepared in conformity with accounting principles generally accepted in the U.S. (“GAAP”). In the opinion of management, these financial statements include all adjustments (consisting of normal recurring accruals and adjustments) necessary to present fairly, in all material respects, the Company’s interim financial position, results of operations and cash flows. However, the results of operations for the periods presented are not necessarily indicative of the results of operations that may be expected for the full year. These financial statements and related notes included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s audited Consolidated Financial Statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Annual Report”). Certain reclassifications have been made to prior period amounts to conform to the current period presentation. Such reclassifications had no material impact on prior period amounts.

2. Summary of Significant Accounting Policies

The Company has provided a discussion of significant accounting policies, estimates, and judgments in “Note 2. Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in its 2015 Annual Report. There have been no changes to the Company’s significant accounting policies since December 31, 2015, other than the recently adopted accounting pronouncements described below.

Recently Adopted Accounting Pronouncements

In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17, Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). ASU 2015-17 requires that all deferred tax liabilities and assets, as well as any related valuation allowance, be classified in the balance sheet as noncurrent. Effective January 1, 2016, the Company early adopted ASU 2015-17 which was applied prospectively and therefore the adoption had no impact on the consolidated balance sheet as of December 31, 2015.

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 is to simplify the presentation of debt issuance costs in financial statements by presenting such costs in the balance sheet as a direct deduction from the related debt rather than as an asset. In August 2015, the FASB issued ASU 2015-15, Interest-Imputation of Interest (Subtopic 835-30) (“ASU 2015-15”), which allows debt issuance costs associated with line-of-credit agreements to be deferred and presented as an asset in the balance sheet, subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings. Effective January 1, 2016, the Company adopted ASU 2015-03 and ASU 2015-15 and reclassified $19.7 million of unamortized debt issuance costs related to the Company’s senior notes from long-term assets to long-term debt in the consolidated balance sheet as of December 31, 2015. Debt issuance costs associated with the Company’s revolving credit facility remain classified as a long-term asset in the consolidated balance sheets.

Recently Issued Accounting Pronouncements

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which amends certain aspects of accounting for share-based payment arrangements. ASU 2016-09 revises or provides alternative accounting for the tax impacts of share-based payment arrangements, forfeitures, minimum statutory tax withholdings, and prescribes certain disclosures to be made in the period of adoption. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. The Company is evaluating ASU 2016-09 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.

-5-

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which significantly changes accounting for leases by requiring that lessees recognize a right-of-use asset and a related lease liability representing the obligation to make lease payments, for virtually all lease transactions. Additional disclosures about an entity’s lease transactions will also be required. ASU 2016-02 defines a lease as “a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment (an identified asset) for a period of time in exchange for consideration.” ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach. The Company is evaluating ASU 2016-02 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.

In May 2014, the FASB issued ASU No. 2014-09, Revenue From Contracts With Customers (Topic 606) (“ASU 2014-09”), which will require entities to 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. ASU 2014-09 will supersede most current guidance related to revenue recognition when it becomes effective. The new standard also will require expanded disclosures regarding the nature, timing, amount and certainty of revenue and cash flows from contracts with customers. The FASB originally intended ASU 2014-09 to be effective for interim and annual reporting periods beginning after December 15, 2016, and permits adoption through the use of either the full retrospective approach or a modified retrospective approach. In July 2015, the FASB issued an update which delays by one year the effective date of ASU 2014-09 and allows for early adoption as of the original effective date. The Company does not intend to early-adopt ASU 2014-09 and has not determined which transition method it will use. The Company is evaluating ASU 2014-09 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.

3. Property and Equipment, Net

As of June 30, 2016 and December 31, 2015, total property and equipment, net consisted of the following:

	June 30, 2016			December 31, 2015
	(In thousands)
Proved properties		$4,330,119			$3,976,511
Accumulated depreciation, depletion and amortization and impairment	(3,187,736		)	(2,607,360		)
Proved properties, net	1,142,383			1,369,151
Unproved properties, not being amortized
Unevaluated leasehold and seismic costs	165,048			280,263
Exploratory wells in progress	1,345			9,432
Capitalized interest	29,216			45,757
Total unproved properties, not being amortized	195,609			335,452
Other property and equipment	23,231			22,677
Accumulated depreciation	(11,756		)	(10,419		)
Other property and equipment, net	11,475			12,258
Total property and equipment, net		$1,349,467			$1,716,861

Capitalized oil and gas property costs within a cost center are amortized on an equivalent unit-of-production method, converting natural gas to barrels of oil equivalent at the ratio of six thousand cubic feet of natural gas to one barrel of crude oil, which represents their approximate relative energy content. Average depreciation, depletion and amortization (“DD&A”) per Boe of proved properties was $13.41 and $23.81 for the three months ended June 30,2016 and 2015, respectively, and $14.32 and $23.63 for the six months ended June 30,2016 and 2015, respectively.

The Company capitalized internal costs of employee compensation and benefits, including stock-based compensation, directly associated with acquisition, exploration and development activities totaling $1.4 million and $5.1 million for the three months ended June 30,2016 and 2015, respectively, and $5.8 million and $10.9 million for the six months ended June 30,2016 and 2015, respectively.

Unproved properties, not being amortized, include unevaluated leasehold and seismic costs associated with specific unevaluated properties, the cost of exploratory wells in progress and related capitalized interest. The Company capitalized interest costs associated with its unevaluated leasehold and seismic costs and exploratory well costs totaling $4.9 million and $9.0 million for the three months ended June 30,2016 and 2015, respectively, and $10.5 million and $18.7 million for the six months ended June 30,2016 and 2015, respectively.

-6-

Impairment of Proved Oil and Gas Properties

Capitalized costs, less accumulated amortization and related deferred income taxes, are limited to the “cost center ceiling” equal to (i) the sum of (A) the present value of estimated future net revenues from proved oil and gas reserves, less estimated future expenditures to be incurred in developing and producing the proved reserves computed using a discount factor of 10%, (B) the costs of unproved properties not being amortized, and (C) the lower of cost or estimated fair value of unproved properties included in the costs being amortized; less (ii) related income tax effects. If the net capitalized costs exceed the cost center ceiling, the excess, on a pre-tax basis, is recognized as an impairment of proved oil and gas properties. An impairment recognized in one period may not be reversed in a subsequent period even if higher crude oil and natural gas prices in the future increase the cost center ceiling applicable to the subsequent period.

The estimated future net revenues used in the cost center ceiling are calculated using the average realized prices for sales of crude oil and natural gas on the first calendar day of each month during the 12-month period prior to the end of the current reporting period (“12-Month Average Realized Price”). Prices are held constant indefinitely and are not changed except where different prices are fixed and determinable from applicable contracts for the remaining term of those contracts. Prices do not include the impact of derivative instruments as the Company elected not to meet the criteria to qualify our derivative instruments for hedge accounting treatment.

In the second quarter of 2016, the Company recorded an after-tax impairment in the carrying value of proved oil and gas properties of $128.1 million ($197.1 million pre-tax). The impairment was due primarily to an 8% decrease in the 12-Month Average Realized Price of crude oil from $43.14 per barrel as of March 31, 2016 to $39.84 per barrel as of June 30, 2016. For the six months ended June 30,2016, the Company recorded after-tax impairments in the carrying value of proved oil and gas properties of $306.5 million ($471.5 million pre-tax) due primarily to a 16% decrease in the 12-Month Average Realized Price of crude oil from $47.24 per barrel as of December 31, 2015 to $39.84 per barrel as of June 30, 2016. There were no impairments of proved oil and gas properties for the three and six months ended June 30,2015.

The Company expects to record an impairment in the carrying value of proved oil and gas properties in the third quarter of 2016. This estimated impairment is primarily due to a forecasted 4% decrease in the 12-Month Average Realized Price of crude oil from $39.84 per barrel as of June 30, 2016 to $38.28 per barrel as of September 30, 2016, which is based on the average realized price for sales of crude oil on the first calendar day of each month for the first 11 months and an estimate for the twelfth month based on a quoted forward price. Further declines in the 12-Month Average Realized Price of crude oil in subsequent quarters may result in additional impairments in the carrying value of proved oil and gas properties.

4. Income Taxes

The Company’s estimated annual effective income tax rates are used to allocate expected annual income tax expense or benefit to interim periods. The rates are the ratio of estimated annual income tax expense or benefit to estimated annual income or loss before income taxes by taxing jurisdiction, except for discrete items, which are significant, unusual or infrequent items for which income taxes are computed and recorded in the interim period in which the discrete item occurs. The estimated annual effective income tax rates are applied to the year-to-date income or loss before income taxes by taxing jurisdiction to determine the income tax expense or benefit allocated to the interim period. The Company updates its estimated annual effective income tax rates on a quarterly basis considering the geographic mix of income or loss attributable to the tax jurisdictions in which the Company operates.

The Company’s income tax (expense) benefit from continuing operations differs from the income tax (expense) benefit computed by applying the U.S. federal statutory corporate income tax rate of 35% to loss from continuing operations before income taxes as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2016			2015			2016			2015
	(In thousands)
Loss from continuing operations before income taxes		($261,934	)		($73,073	)		($573,208	)		($105,987	)
Income tax benefit at the statutory rate	91,677			25,575			200,623			37,095
State income tax (expense) benefit, net of U.S. federal income taxes	1,665			(145		)	3,284			(221		)
Deferred tax assets valuation allowance	(93,522		)	—			(204,201		)	—
Texas Franchise Tax rate reduction, net of U.S. federal income taxes	—			1,671			—			1,671
Other	(12		)	(998		)	(19		)	(1,004		)
Income tax (expense) benefit from continuing operations		($192	)		$26,103			($313	)		$37,541

Deferred Tax Assets Valuation Allowance

Deferred tax assets are recorded for net operating losses and temporary differences between the book and tax basis of assets and

liabilities expected to produce tax deductions in future periods. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those deferred tax assets would be deductible. The Company assesses the realizability of its deferred tax assets each period by considering whether it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Company considers all available evidence (both positive and negative) when determining whether a valuation allowance is required. In making this assessment, the Company evaluated possible sources of taxable income that may be available to realize the deferred tax assets, including projected future taxable income, the reversal of existing temporary differences, taxable income in carryback years and available tax planning strategies.

A significant item of objective negative evidence considered was the cumulative historical three year pre-tax loss and a net deferred tax asset position at June 30, 2016, driven primarily by the impairments of proved oil and gas properties recognized during the second half of 2015 and the first half of 2016, which limits the ability to consider other subjective evidence such as the Company’s potential for future growth. The Company has concluded that it is more likely than not the net deferred tax assets will not be realized and recorded an additional valuation allowance totaling $93.5 million against the net deferred tax assets as of June 30, 2016, reducing the net deferred tax assets to zero.

The Company will continue to evaluate whether the valuation allowance is needed in future reporting periods. The valuation allowance will remain until the Company can conclude that the net deferred tax assets are more likely than not to be realized. Future events or new evidence which may lead the Company to conclude that it is more likely than not its net deferred tax assets will be realized include, but are not limited to, cumulative historical pre-tax earnings, improvements in crude oil prices, and taxable events that could result from one or more transactions. The valuation allowance does not preclude the Company from utilizing the tax attributes if the Company recognizes taxable income. As long as the Company concludes that the valuation allowance against net deferred tax assets is necessary, the Company likely will have no deferred income tax expense or benefit.

Senior Secured Revolving Credit Facility

The Company has a senior secured revolving credit facility with a syndicate of banks that, as of June 30, 2016, had a borrowing base of $600.0 million, with $61.0 million of borrowings outstanding with a weighted average interest rate of 2.44%. As of June 30, 2016, the Company also had $0.4 million in letters of credit outstanding, which reduce the amounts available under the revolving credit facility. The credit agreement governing the revolving credit facility provides for interest-only payments until July 2, 2018, when the credit agreement matures and any outstanding borrowings are due. The borrowing base under the credit agreement is subject to regular redeterminations in the Spring and Fall of each year, as well as special redeterminations described in the credit agreement, in each case which may reduce the amount of the borrowing base. The amount the Company is able to borrow with respect to the borrowing base is subject to compliance with the financial covenants and other provisions of the credit agreement. Each of the capitalized terms which are not defined in this note shall have the meaning given to such terms in the credit agreement.

On May 3, 2016, the Company entered into an amendment to the credit agreement (the “Eighth Amendment”) to, among other things (i) replace the Total Debt to EBITDA ratio covenant with a Total Secured Debt to EBITDA ratio covenant that requires such ratio not to exceed 2.00 to 1.00, (ii) add a covenant requiring a minimum EBITDA to Interest Expense ratio of at least 2.50 to 1.00, (iii) reduce the Borrowing Base under the credit facility from $685.0 million to $600.0 million until the next redetermination thereof, (iv) increase the required mortgage coverage on the total value of the oil and gas properties included in the Company’s most recent reserve report from 80% to 90%, (v) require that the Company’s deposit accounts and securities accounts (subject to certain exclusions) become subject to control agreements, (vi) limit the amount of additional senior notes that can be issued by the Company to $400.0 million, (vii) restrict the Company from making borrowings under the credit facility if the Company has

or, after giving effect to the borrowing, will have a Consolidated Cash Balance in excess of $50.0 million, (viii) require mandatory prepayment of borrowings to the extent the Consolidated Cash Balance exceeds $50.0 million if either (a) the Company’s ratio of Total Debt to EBITDA exceeds 3.50 to 1.00 or (b) the availability under the credit facility is equal to or less than 20% of the then effective Borrowing Base, (ix) increase the margin on all loans by 0.50%, and (x) increase the commitment fee from 0.375% to 0.50% when utilization of lender commitments is less than 50%.

The obligations of the Company under the credit agreement are guaranteed by the Company’s material domestic subsidiaries and are secured by liens on substantially all of the Company’s assets, including a mortgage lien on oil and gas properties having at least 90% of the proved reserve value of the oil and gas properties included in the determination of the borrowing base.

Borrowings outstanding under the credit agreement bear interest at the Company’s option at either (i) a base rate for a base rate loan plus the margin set forth in the table below, where the base rate is defined as the greatest of the prime rate, the federal funds rate plus 0.50% and the adjusted LIBO rate plus 1.00%, or (ii) an adjusted LIBO rate for a Eurodollar loan plus the margin set forth in the table below. The Company also incurs commitment fees as set forth in the table below based on the unused portion of lender commitments, which are included in interest expense, net.

Ratio of Outstanding Borrowings and Letters of Credit to Lender Commitments	Applicable Margin for Base Rate Loans	Applicable Margin for Eurodollar Loans	Commitment Fee
Less than 25%	1.00%	2.00%	0.500%
Greater than or equal to 25% but less than 50%	1.25%	2.25%	0.500%
Greater than or equal to 50% but less than 75%	1.50%	2.50%	0.500%
Greater than or equal to 75% but less than 90%	1.75%	2.75%	0.500%
Greater than or equal to 90%	2.00%	3.00%	0.500%

As discussed above, the Company is subject to certain covenants under the terms of the credit agreement, which include the maintenance of the following financial covenants determined as of the last day of each quarter: (1) a ratio of Total Secured Debt to EBITDA of not more than 2.00 to 1.00; (2) a Current Ratio of not less than 1.00 to 1.00; and (3) a ratio of EBITDA to Interest Expense of not less than 2.50 to 1.00. As defined in the credit agreement, Total Secured Debt excludes debt issuance costs, EBITDA includes the last four quarters after giving pro forma effect to EBITDA for material acquisitions and dispositions of oil and gas properties, Interest Expense is comprised of the aggregate interest expense paid in cash for the last four quarters, and the Current Ratio includes an add back of the unused portion of lender commitments. As of June 30, 2016, the ratio of Total Secured Debt to EBITDA was 0.15 to 1.00, the Current Ratio was 3.23 to 1.00 and the ratio of EBITDA to Interest Expense was 4.60 to 1.00. Because the financial covenants are determined as of the last day of each quarter, the ratios can fluctuate significantly period to period as the level of borrowings outstanding under the credit agreement are impacted by the timing of cash flows from operations, capital expenditures, acquisitions and dispositions of oil and gas properties and securities offerings.

The credit agreement also places restrictions on the Company and certain of its subsidiaries with respect to additional indebtedness, liens, dividends and other payments to shareholders, repurchases or redemptions of the Company’s common stock, redemptions of senior notes, investments, acquisitions, mergers, asset dispositions, transactions with affiliates, hedging transactions and other matters. Further, the credit agreement restricts the Company from making borrowings under the credit facility if the Company has or, after giving effect to the borrowing, will have a cash balance that exceeds $50.0 million and requires mandatory prepayment of borrowings to the extent the cash balance is in excess of $50.0 million under certain circumstances as described above.

The credit agreement is subject to customary events of default, including in connection with a change in control. If an event of default occurs and is continuing, the lenders may elect to accelerate amounts due under the credit agreement (except in the case of a bankruptcy event of default, in which case such amounts will automatically become due and payable).

6. Commitments and Contingencies

From time to time, the Company is party to certain legal actions and claims arising in the ordinary course of business. While the outcome of these events cannot be predicted with certainty, management does not currently expect these matters to have a materially adverse effect on the financial position or results of operations of the Company.

The results of operations and financial position of the Company continue to be affected from time to time in varying degrees by domestic and foreign political developments as well as legislation and regulations pertaining to restrictions on crude oil and natural gas production, imports and exports, natural gas regulation, tax increases, environmental regulations and cancellation of contract rights. Both the likelihood and overall effect of such occurrences on the Company vary greatly and are not predictable.

Income tax benefit		$3,812			$1,731			$7,845			$5,179

8. Earnings Per Share

Basic loss from continuing operations per common share is based on the weighted average number of shares of common stock outstanding during the period. Diluted loss from continuing operations per common share is based on the weighted average number of common shares and all potentially dilutive common shares outstanding during the period which include restricted stock awards and units, performance share awards, stock options and warrants. The Company includes the number of restricted stock awards and units, stock options and warrants in the calculation of diluted weighted average shares outstanding when the grant date or exercise prices are less than the average market prices of the Company’s common stock for the period. The Company includes the number of performance share awards in the calculation of diluted weighted average common shares outstanding based on the number of shares, if any, that would be issuable as if the end of the period was the end of the performance period. When a loss from continuing operations exists, all potentially dilutive common shares outstanding are anti-dilutive and therefore excluded from the calculation of diluted weighted average shares outstanding.

Supplemental loss from continuing operations per common share information is provided below:

	Three Months Ended June 30,						Six Months Ended June 30,
	2016			2015			2016			2015
	(In thousands, except per share amounts)
Loss from Continuing Operations		($262,126	)		($46,970	)		($573,521	)		($68,446	)
Basic weighted average common shares outstanding	58,806			51,225			58,583			48,827
Effect of dilutive instruments	—			—			—			—
Diluted weighted average common shares outstanding	58,806			51,225			58,583			48,827

Diluted		($4.46	)		($0.92	)		($9.79	)		($1.40	)

For the three and six months ended June 30,2016 and 2015, the Company reported a loss from continuing operations. As a result, the calculation of diluted weighted average common shares outstanding excluded the anti-dilutive effect of 0.7 million potentially dilutive common shares outstanding for the three months ended June 30,2016 and 2015 and 0.6 million and 0.7 million potentially dilutive common shares outstanding for the six months ended June 30,2016 and 2015, respectively.

9. Derivative Instruments

The Company uses commodity derivative instruments to reduce its exposure to commodity price volatility for a substantial, but varying, portion of its forecasted crude oil and natural gas production and thereby achieve a more predictable level of cash flows to support the Company’s drilling and completion capital expenditure program. The Company does not enter into derivative instruments for speculative or trading purposes. As of June 30, 2016, the Company’s commodity derivative instruments consisted of fixed price swaps, costless collars, and purchased and sold call options, which are described below.

Fixed Price Swaps: The Company receives a fixed price and pays a variable market price to the counterparties over specified periods for contracted volumes.

-10-

Costless Collars: A collar is a combination of options including a purchased put option (fixed floor price) and a sold call option (fixed ceiling price) and allows the Company to benefit from increases in commodity prices up to the fixed ceiling price and protect the Company from decreases in commodity prices below the fixed floor price. At settlement, if the market price is below the fixed floor price or is above the fixed ceiling price, the Company receives the fixed price and pays the market price. If the market price is between the fixed floor price and fixed ceiling price, no payments are due from either party. These contracts were executed contemporaneously with the same counterparties and were premium neutral such that no premiums were paid to or received from the counterparties.

Sold Call Options: These contracts give the counterparties the right, but not the obligation, to buy contracted volumes from the Company over specified periods and prices in the future. At settlement, if the market price exceeds the fixed price of the call option, the Company pays the counterparty the excess. If the market price settles below the fixed price of the call option, no payment is due from either party.

Purchased Call Options: These contracts give the Company the right, but not the obligation, to buy contracted volumes from the counterparties over specified periods and prices in the future. At settlement, if the market price exceeds the fixed price of the call option, the counterparties pay the Company the excess. If the market price settles below the fixed price of the call option, no payment is due from either party. The Company nets its purchased call options with its sold call options for the years 2018 through 2020 in the open crude oil derivative positions table below.

The following sets forth a summary of the Company’s open crude oil derivative positions at average NYMEX prices as of June 30, 2016:

Period	Type of Contract	Crude Oil Volumes (in Bbls/d)	Weighted Average Floor Price ($/Bbl)		Weighted Average Ceiling Price ($/Bbl)
July - December 2016	Fixed Price Swaps	9,750		$60.03
July - December 2016	Costless Collars	4,000		$50.00	$76.50
January - June 2017	Fixed Price Swaps	12,000		$50.13
FY 2018	Sold Call Options	2,488				$60.00
FY 2018	Sold Call Options	900				$75.00
FY 2019	Sold Call Options	2,975				$62.50
FY 2019	Sold Call Options	900				$77.50
FY 2020	Sold Call Options	3,675				$65.00
FY 2020	Sold Call Options	900			$80.00

The following sets forth a summary of the Company’s open natural gas derivative positions at average NYMEX prices as of June 30, 2016:

Period	Type of Contract	Natural Gas Volumes (in MMBtu/d)	Weighted Average Ceiling Price ($/MMBtu)
FY 2017	Sold Call Options	33,000		$3.00
FY 2018	Sold Call Options	33,000		$3.25
FY 2019	Sold Call Options	33,000		$3.25
FY 2020	Sold Call Options	33,000		$3.50

In February 2015, the Company entered into derivative transactions offsetting its then existing crude oil derivative positions covering the periods from March 2015 through December 2016. As a result of the offsetting derivative transactions, the Company locked in $166.4 million of cash flows, of which $9.3 million and $40.0 million were received due to contract settlements during the three months ended June 30,2016 and 2015, respectively, and $27.6 million and $40.0 million were received due to contract settlements during the six months ended June 30,2016 and 2015, respectively. These cash flows are included in the “(Gain) loss on derivatives, net” in the consolidated statements of operations. As of June 30, 2016, the fair value of the remaining locked in cash flows is $19.9 million, all of which is a current asset and is classified as “Derivative assets” in the consolidated balance sheets. The derivative assets associated with the offsetting derivative transactions are not subject to price risk and the locked in cash flows will be received as the applicable contracts settle. The offsetting derivative transactions are not included in the table above.

In February 2016, the Company sold out-of-the-money natural gas call options for the years 2017 through 2020 and used the associated premium value to obtain a higher weighted average fixed price of $50.27 per Bbl on 6,000 Bbls/d of newly executed crude oil fixed price swaps for the first half of 2017. These out-of-the-money natural gas call options and in-the-money crude oil fixed price swaps were executed contemporaneously with the same counterparty, therefore, no cash premiums were paid to or received from the counterparty as the premium value associated with the natural gas call options was immediately applied to the crude oil fixed price swaps.

In March 2016, the Company sold 6,000 Bbls/d of in-the-money crude oil fixed price swaps for the first half of the year 2017 at a weighted average fixed price of $50.00 per Bbl. In order to obtain this higher weighted average fixed price, the Company incurred net premiums of approximately $5.6 million, of which approximately $2.8 million was paid during the second quarter of 2016 with the remaining $2.8 million to be paid during the third quarter of 2016.

For the three months ended June 30,2016 and 2015, the Company recorded in the consolidated statements of operations a loss on derivatives, net of $52.2 million and $12.6 million, respectively. For the six months ended June 30,2016 and 2015, the Company recorded in the consolidated statements of operations a loss on derivatives, net of $41.7 million and a gain on derivatives, net of $13.8 million, respectively.

The Company typically has numerous hedge positions that span several time periods and often result in both fair value asset and liability positions held with that counterparty, which positions are all offset to a single fair value asset or liability at the end of each reporting period, including the deferred premiums associated with its hedge positions. The Company nets its derivative instrument fair values executed with the same counterparty pursuant to ISDA master agreements, which provide for net settlement over the term of the contract and in the event of default or termination of the contract. The fair value of derivative instruments where the Company is in a net asset position with its counterparties as of June 30, 2016 and December 31, 2015 totaled $15.1 million and $119.6 million, respectively, and is summarized by counterparty in the table below:

Counterparty	June 30, 2016		December 31, 2015
Wells Fargo	47	%	35	%
Regions	31	%	9	%
Union Bank	20	%	5	%
Capital One	2	%	1	%
Societe Generale	—	%	37	%
Citibank	—	%	13	%
Total	100	%	100	%

The counterparties to the Company’s derivative instruments are also lenders under the Company’s credit agreement which allows the Company to satisfy any need for margin obligations associated with derivative instruments where the Company is in a net liability position with its counterparties with the collateral securing the credit agreement, thus eliminating the need for independent collateral posting.

Because each of the counterparties have investment grade credit ratings, the Company believes it does not have significant credit risk and accordingly does not currently require its counterparties to post collateral to support the net asset positions of its derivative instruments. As such, the Company is exposed to credit risk to the extent of nonperformance by the counterparties to its derivative instruments. Although the Company does not currently anticipate such nonperformance, it continues to monitor the credit ratings of its counterparties.

10. Fair Value Measurements

Accounting guidelines for measuring fair value establish a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows:

Level 1 – Observable inputs such as quoted prices in active markets at the measurement date for identical, unrestricted assets or liabilities.

Level 2 – Other inputs that are observable directly or indirectly such as quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3 – Unobservable inputs for which there is little or no market data and which the Company makes its own assumptions about how market participants would price the assets and liabilities.

-12-

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following tables summarize the location and amounts of the Company’s assets and liabilities measured at fair value on a recurring basis as presented in the consolidated balance sheets as of June 30, 2016 and December 31, 2015. All items included in the tables below are Level 2 inputs within the fair value hierarchy:

Derivative liabilities-non current	(22,313		)	9,665			(12,648		)
Total		$119,550			$—			$119,550

The fair values of the Company’s derivative assets and liabilities are based on a third-party industry-standard pricing model that uses market data obtained from third-party sources, including quoted forward prices for crude oil and natural gas, discount rates and volatility factors. The fair values are also compared to the values provided by the counterparties for reasonableness and are adjusted for the counterparties’ credit quality for derivative assets and the Company’s credit quality for derivative liabilities.

The derivative asset and liability fair values reported in the consolidated balance sheets that pertain to the Company’s derivative instruments are as of a particular point in time and subsequently change as these estimates are revised to reflect actual results, changes in market conditions and other factors. However, the fair value of the net derivative asset attributable to the offsetting crude oil derivative transactions are not subject to price risk as changes in the fair value of the original positions are offset by changes in the fair value of the offsetting positions. The Company typically has numerous hedge positions that span several time periods and often result in both derivative assets and liabilities with the same counterparty, which positions are all offset to a single derivative asset or liability in the consolidated balance sheets, including the deferred premiums associated with its hedge positions. The Company nets the fair values of its derivative assets and liabilities associated with derivative instruments executed with the same counterparty pursuant to ISDA master agreements, which provide for net settlement over the term of the contract and in the event of default or termination of the contract. The Company had no transfers into Level 1 and no transfers into or out of Level 2 for the six months ended June 30,2016 and 2015.

-13-

Fair Value of Other Financial Instruments

The Company’s other financial instruments consist of cash and cash equivalents, receivables, payables and long-term debt, which are classified as Level 1 under the fair value hierarchy. The carrying amounts of cash and cash equivalents, receivables, and payables approximate fair value due to the highly liquid or short-term nature of these instruments. The carrying amount of long-term debt under the Company’s revolving credit facility approximates fair value as borrowings bear interest at variable rates. The following table presents the carrying amounts of the Company’s senior notes and other long-term debt, net of debt premiums and debt issuance costs, with the fair values of each based on quoted market prices.

	June 30, 2016				December 31, 2015
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(In thousands)
7.50% Senior Notes due 2020		$592,818		$607,500		$592,203		$528,000

Other long-term debt due 2028	4,425		4,259		4,425		4,182

11. Condensed Consolidating Financial Information

The rules of the SEC require that condensed consolidating financial information be provided for a subsidiary that has guaranteed the debt of a registrant issued in a public offering, where the guarantee is full, unconditional and joint and several and where the voting interest of the subsidiary is 100% owned by the registrant. The Company is, therefore, presenting condensed consolidating financial information on a parent company, combined guarantor subsidiaries, combined non-guarantor subsidiaries and consolidated basis and should be read in conjunction with the consolidated financial statements. The financial information may not necessarily be indicative of results of operations, cash flows, or financial position had such guarantor subsidiaries operated as independent entities.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is management’s discussion and analysis of the significant factors that affected the financial position and results of operations of Carrizo Oil & Gas, Inc. and its subsidiaries (collectively, the “Company”) during the periods included in the accompanying unaudited consolidated financial statements. You should read this in conjunction with the unaudited interim consolidated financial statements included in this Quarterly Report on Form 10-Q and the discussion under “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Annual Report”).

General Overview

Production, Commodity Prices and Revenue. Total production for the three months ended June 30,2016 increased 15% from the three months ended June 30,2015 to 41,533 Boe/d, due primarily to increased production from new wells in the Eagle Ford. Production from the Eagle Ford comprised 73% of our total production for the second quarter of 2016. Crude oil production for the three months ended June 30,2016 was 23,942 Bbls/d, an increase of 7% from the three months ended June 30,2015, primarily driven by strong performance from our wells in the Eagle Ford, which averaged 21,186 Bbls/d. Revenues for the second quarter of 2016 decreased from the second quarter of 2015 to $107.3 million driven primarily by a 23% decrease in average realized crude oil prices, partially offset by increased crude oil production. For further discussion of production, commodity prices and revenue, see “—Results of Operations” below.

Operational Highlights. See the table below for details of our operated drilling and completion activity by region:

Financing Activities. On May 3, 2016, we entered into an amendment to the credit agreement governing the revolving credit facility (the “Eighth Amendment”) which, among other things, (i) replaced the Total Debt to EBITDA ratio covenant with a Total Secured Debt to EBITDA ratio covenant that requires such ratio not to exceed 2.00 to 1.00, (ii) added a covenant requiring a minimum EBITDA to Interest Expense ratio of at least 2.50 to 1.00, and (iii) reduced the Borrowing Base under the credit facility from $685.0 million to $600.0 million until the next redetermination thereof. See “Note 5. Long-Term Debt” for additional details.

2016 Capital Expenditure Plan. We are increasing our 2016 drilling and completion capital expenditure plan to a range of $370.0 million to $380.0 million from a range of $270.0 million to $290.0 million as a result of the improvement in the commodity price outlook since the beginning of 2016. Our 2016 leasehold and seismic capital expenditure plan remains unchanged at $20.0 million. Approximately 80% of our second quarter 2016 drilling and completion capital expenditures were in the Eagle Ford. Approximately 85% of the 2016 drilling and completion capital expenditure plan is allocated to the continued development of the Eagle Ford. See “—Liquidity and Capital Resources—2016 Capital Expenditure Plan and Funding Strategy” for additional details.

Three Months Ended June 30,2016, Compared to the Three Months Ended June 30,2015

The following table summarizes total production volumes, daily production volumes, average realized prices and revenues for the three months ended June 30,2016 and 2015:

	Three Months Ended June 30,				2016 Period Compared to 2015 Period
	2016		2015		Increase (Decrease)			% Increase (Decrease)
Total production volumes -
Crude oil (MBbls)	2,179		2,028		151			7	%

Average realized prices -
Crude oil ($ per Bbl)		$42.04		$54.86		($12.82	)	(23	%)
NGLs ($ per Bbl)	12.76		11.95		0.81			7	%
Natural gas ($ per Mcf)	1.43		1.49		(0.06		)	(4	%)
Total average realized price ($ per Boe)		$28.39		$37.57		($9.18	)	(24	%)
Revenues (In thousands) -
Crude oil		$91,608		$111,257		($19,649	)	(18	%)
NGLs	6,063		3,799		2,264			60	%

Total revenues		$107,324		$123,494		($16,170	)	(13	%)

Revenues for the three months ended June 30,2016 decreased 13% to $107.3 million from $123.5 million for the same period in 2015 due primarily to the decrease in average realized crude oil prices, partially offset by the increase in crude oil production. Production volumes for the three months ended June 30,2016 and 2015 were 41,533 Boe/d and 36,118 Boe/d, respectively an increase of 15%. The increase in production from the second quarter of 2015 to the second quarter of 2016 was due primarily to increased production from new wells in the Eagle Ford, partially offset by normal production declines.

Lease operating expenses for the three months ended June 30,2016 decreased to $23.1 million ($6.11 per Boe) from $23.4 million ($7.11 per Boe) for the same period in 2015. The decrease in lease operating expenses is due primarily to a decrease in produced water disposal costs as a result of an increase in the proportion of produced water volumes being transported to disposal sites via pipeline instead of truck, partially offset by increased production from new wells in the Eagle Ford. The decrease in lease operating expense per Boe is due primarily to the lower produced water disposal costs described above.

Production taxes decreased to $4.6 million (or 4.3% of revenues) for the three months ended June 30,2016 from $5.0 million (or 4.1% of revenues) for the same period in 2015 as a result of the decrease in crude oil and natural gas revenues, partially offset by increased crude oil production from new wells in the Eagle Ford. The increase in production taxes as a percentage of revenues

-21-

for the three months ended June 30,2016 as compared to the same period in 2015 is due primarily to an increased proportion of total revenues attributable to natural gas production in Eagle Ford, which is taxed at a higher rate than crude oil.

Ad valorem taxes decreased to $0.5 million for the three months ended June 30,2016 from $1.7 million for the same period in 2015. The decrease in ad valorem taxes is due to updating our annual estimate of ad valorem taxes based on the property tax valuations we received during the second quarter which were lower than our previous estimates, partially offset by an increase attributable to new wells drilled in Eagle Ford in 2015.

Depreciation, depletion and amortization (“DD&A”) expense for the second quarter of 2016 decreased $27.3 million to $52.0 million ($13.75 per Boe) from the DD&A expense for the second quarter of 2015 of $79.3 million ($24.13 per Boe). The decrease in DD&A expense is attributable to the decrease in the DD&A rate per Boe, which is due primarily to impairments of our proved oil and gas properties recorded in the second half of 2015 and the first quarter of 2016 as well as reductions in estimated future development costs as a result of drilling efficiencies and reduced service costs that occurred throughout 2015 and the first half of 2016. The components of our DD&A expense were as follows:

	Three Months Ended June 30,
	2016		2015
	(In thousands)
DD&A of proved oil and gas properties		$50,690		$78,262
Depreciation of other property and equipment	665		364
Amortization of other assets	268		435
Accretion of asset retirement obligations	343		270
Total DD&A		$51,966		$79,331

We recorded an after-tax impairment in the carrying value of proved oil and gas properties of $128.1 million ($197.1 million pre-tax) for the three months ended June 30,2016 due primarily to an 8% decrease in the 12-Month Average Realized Price, as defined in “Note 3. Property and Equipment, Net,” of crude oil from $43.14 per barrel as of March 31, 2016 to $39.84 per barrel as of June 30, 2016. There were no impairments of proved oil and gas properties for the three months ended June 30,2015.

General and administrative expense, net increased to $19.6 million for the three months ended June 30,2016 from $19.1 million for the corresponding period in 2015. The increase was primarily due to an increase in stock-based compensation expense, net as a result of an increase in the fair value of stock appreciation rights for the three months ended June 30,2016 compared to a decrease in fair value for the three months ended June 30,2015 partially offset by lower accruals for estimated bonuses in the second quarter of 2016 as compared to the same period of 2015.

The loss on derivatives, net for the three months ended June 30,2016 amounted to $52.2 million due primarily to the upward shift in the futures curve of forecasted commodity prices for crude oil and natural gas from April 1, 2016 to June 30, 2016 and new crude oil and natural gas hedge positions executed subsequent to June 30, 2015. The loss on derivatives, net for the three months ended June 30,2015 amounted to $12.6 million due primarily to new crude oil hedge positions executed during 2015 and the upward shift in the futures curve of forecasted commodity prices for crude oil from April 1, 2015 to June 30, 2015.

Interest expense, net for the three months ended June 30,2016 was $19.0 million as compared to $17.0 million for the same period in 2015. The increase was due primarily to the decrease in capitalized interest as a result of lower balances of unproved properties not being amortized in the second quarter of 2016 as compared to the second quarter of 2015, partially offset by lower interest associated with the $650.0 million of 6.25% Senior Notes that were issued in April 2015 as compared to the interest associated with the $600.0 million of 8.625% Senior Notes that were redeemed in April 2015. The components of our interest expense, net were as follows:

	Three Months Ended June 30,
	2016			2015
	(In thousands)
Interest expense on Senior Notes		$21,455			$23,737
Interest expense on revolving credit facility	989			960
Amortization of debt issuance costs, premiums, and discounts	1,134			1,225
Other interest expense	260			1
Capitalized interest	(4,828		)	(8,924		)
Interest expense, net		$19,010			$16,999

-22-

The effective income tax rate for the second quarter of 2016 and 2015 was (0.1%) and 35.7%, respectively. The (0.1%) effective tax rate for the three months ended June 30,2016 was due primarily to a valuation allowance of $93.5 million that was recorded against our net deferred tax assets during the second quarter of 2016. No valuation allowance was recorded during the second quarter of 2015.

Total revenues		$188,586		$223,544		($34,958	)	(16	%)

Revenues for the six months ended June 30,2016 decreased 16% to $188.6 million from $223.5 million for the same period in 2015 primarily due to the decrease in average realized crude oil prices, partially offset by the increase in crude oil production. Production volumes for the six months ended June 30,2016 and 2015 were 41,779 Boe/d and 35,361 Boe/d, respectively. The increase in production from the six months ended June 30,2015 to the six months ended June 30,2016 was primarily due to increased production from new wells in the Eagle Ford.

Lease operating expenses for the six months ended June 30,2016 increased to $46.8 million ($6.15 per Boe) from $45.1 million ($7.05 per Boe) for the same period in 2015. The increase in lease operating expenses is primarily due to increased production from new wells in the Eagle Ford, partially offset by reduced costs due primarily to a decrease in produced water disposal costs as a result of an increase in the proportion of produced water volumes being transported to disposal sites via pipeline

-23-

instead of truck. The decrease in lease operating expense per Boe is primarily due to the lower produced water disposal costs described above.

Production taxes decreased to $8.1 million (or 4.3% of revenues) for the six months ended June 30,2016 from $9.0 million (or 4.0% of revenues) for the same period in 2015 as a result of the decrease in crude oil and natural gas revenues, partially offset by increased crude oil production. The increase in production taxes as a percentage of revenues for the six months ended June 30,2016 is primarily due to a decreased proportion of total revenues attributable to Marcellus production, which is not subject to production taxes.

Ad valorem taxes decreased to $2.5 million for the six months ended June 30,2016 from $4.8 million for the same period in 2015. The decrease in ad valorem taxes is due to updating our annual estimate of ad valorem taxes based on the property tax valuations we received during the second quarter which were lower than our previous estimates, partially offset by an increase to new wells drilled in Eagle Ford in 2015.

DD&A expense for the six months ended June 30,2016 decreased $41.7 million to $111.5 million ($14.67 per Boe) from $153.2 million ($23.94 per Boe) for the same period in 2015. The decrease in DD&A expense is attributable to the decrease in the DD&A rate per Boe, which is due primarily to impairments of our proved oil and gas properties recorded in the second half of 2015 and the first quarter of 2016 as well as reductions in estimated future development costs as a result of drilling efficiencies and reduced service costs that occurred throughout 2015 and the first half of 2016. The components of our DD&A expense were as follows:

	Six Months Ended June 30,
	2016		2015
	(In thousands)
DD&A of proved oil and gas properties		$108,893		$151,234
Depreciation of other property and equipment	1,338		750
Amortization of other assets	641		691

We recorded after-tax impairments in the carrying value of proved oil and gas properties of $306.5 million ($471.5 million pre-tax) for the six months ended June 30,2016 due primarily to declines in the 12-Month Average Realized Price, as defined in “Note 3. Property and Equipment, Net,” of crude oil from $47.24 per barrel as of December 31, 2015 to $39.84 per barrel as of June 30, 2016. There were no impairments of proved oil and gas properties for the six months ended June 30,2015.

General and administrative expense decreased to $40.9 million for the six months ended June 30,2016 from $50.7 million for the same period in 2015. The decrease was primarily due to lower annual bonuses awarded in the first quarter of 2016 compared to the first quarter of 2015 and lower accruals for estimated bonuses in the first half of 2016 as compared to the same period in 2015.

The loss on derivatives, net for the six months ended June 30,2016 amounted to $41.7 million primarily due to crude oil and natural gas hedge positions executed subsequent to June 30, 2015 as well as the upward shift in the futures curve of forecasted commodity prices for crude oil from January 1, 2016 (or the subsequent date on which new contracts were entered into) to June 30, 2016. The gain on derivatives, net for the six months ended June 30,2015 amounted to $13.8 million primarily due to the downward shift in the futures curve of forecasted commodity prices for crude oil during the first quarter of 2015, prior to our lock-in of our then existing crude oil derivative positions, and the downward shift in the futures curve of forecasted commodity prices for natural gas from January 1, 2015 to June 30, 2015.

Interest expense, net for the six months ended June 30,2016 was $37.7 million as compared to $35.2 million for the same period in 2015. The increase was due primarily to the decrease in capitalized interest as a result of lower balances of unevaluated leasehold and seismic costs and exploratory well costs in the first half of 2016 as compared to the first half of 2015, partially offset by lower interest associated with the $650.0 million of 6.25% Senior Notes that were issued in April 2015 as compared to the interest associated with the $600.0 million of 8.625% Senior Notes that were redeemed in April 2015. The components of our interest expense, net were as follows:

	Six Months Ended June 30,
	2016			2015
	(In thousands)
Interest expense on Senior Notes		$42,910			$47,973
Interest expense on revolving credit facility	1,666			2,165
Amortization of debt issuance costs, premiums, and discounts	3,110			2,622
Other interest expense	514			1,107
Capitalized interest	(10,477		)	(18,672		)
Interest expense, net		$37,723			$35,195

The effective income tax rate for the six months ended June 30,2016 and 2015 was (0.1%) and 35.4%, respectively. The variance from the U.S. Federal statutory rate of 35% for the six months ended June 30,2016 was primarily due to a valuation allowance of $204.2 million that was recorded against our net deferred tax assets during the six months ended June 30,2016. The variance from the U.S. Federal statutory rate of 35% for the six months ended June 30,2015 was due to the impact of state income taxes including a rate reduction in the Texas Franchise Tax and other items.

Liquidity and Capital Resources

2016 Capital Expenditure Plan and Funding Strategy. Our 2016 drilling and completion capital expenditure plan has been increased to $370.0 million to $380.0 million from the previous range of $270.0 million to $290.0 million. This increase is primarily due to the improvement in the commodity price outlook since the beginning of 2016. Our 2016 leasehold and seismic capital expenditure plan remains unchanged at $20.0 million. We currently intend to finance our 2016 capital expenditure plan primarily from the sources described below under “—Sources and Uses of Cash.” Our capital program could vary depending upon various factors, including the availability and cost of drilling rigs, land and industry partner issues, our available cash flow and financing, success of drilling programs, weather delays, commodity prices, market conditions, the acquisition of leases with drilling commitments and other factors. Below is a summary of capital expenditures through June 30, 2016:

	Three Months Ended				Six Months Ended
	March 31, 2016		June 30, 2016		June 30, 2016

(1) Our capital expenditure plan and the capital expenditures included above exclude capitalized general and administrative expense, capitalized interest and capitalized asset retirement obligations.

Sources and Uses of Cash. Our primary use of cash is related to our drilling and completion capital expenditure plan and, to a lesser extent, our leasehold and seismic capital expenditure plan. For the six months ended June 30,2016, we funded our capital expenditures with cash provided by operations and borrowings under our revolving credit facility. Potential sources of future liquidity include the following:

• Cash provided by operations. Cash flows from operations are highly dependent on crude oil prices. As such, we hedge a portion of our forecasted production to reduce our exposure to commodity price volatility in order to achieve a more predictable level of cash flows.

• Borrowings under our revolving credit facility. As of July 29, 2016, our revolving credit facility had a borrowing base of $600.0 million, with $60.0 million of borrowings outstanding and $0.4 million in letters of credit issued, which reduce the amounts available under our revolving credit facility. The amount we are able to borrow is subject to

-25-

compliance with the financial covenants and other provisions of the credit agreement governing our revolving credit facility.

• Asset sales. In order to fund our capital expenditure plan, we may consider the sale of certain properties or assets that are not part of our core business or are no longer deemed essential to our future growth, provided we are able to sell such assets on terms that are acceptable to us. We continue to explore sales of non-core properties.

• Securities offerings. As situations or conditions arise, we may choose to issue debt, equity or other securities to supplement our cash flows. However, we may not be able to obtain such financing on terms that are acceptable to us, or at all.

• Joint ventures. Joint ventures with third parties through which such third parties fund a portion of our exploration activities to earn an interest in our exploration acreage or purchase a portion of interests, or both.

Overview of Cash Flow Activities.Net cash provided by operating activities from continuing operations was $126.0 million and $165.7 million for the six months ended June 30,2016 and 2015, respectively. The change was due primarily to a decrease in crude oil revenues, resulting primarily from lower average realized crude oil prices in 2016 as compared to 2015, a decrease in the net cash received from derivative settlements, and an increase in working capital requirements, partially offset by a decrease in cash general and administrative expenses.

Net cash used in investing activities from continuing operations was $226.1 million and $382.6 million for the six months ended June 30,2016 and 2015, respectively. The decrease was due primarily to a reduction in our capital expenditures in 2016 as compared to 2015 and a decrease in the components of working capital associated with investing activities as a result of reduced drilling and completion activity.

Net cash provided by financing activities from continuing operations was $59.3 million and $210.2 million for the six months ended June 30,2016 and 2015, respectively. The decrease from 2015 to 2016 was due to the proceeds from the issuance of common stock in March 2015 and the issuance of the 6.25% Senior Notes in April 2015, as well as reduced borrowings on our revolving credit facility in the six months ended June 30,2016 as compared to the same period in 2015, partially offset by the tender and redemption of the 8.625% Senior Notes during the second quarter of 2015 and the payment of the deferred purchase payment in February 2015.

Liquidity/Cash Flow Outlook. Economic downturns may adversely affect our ability to access capital markets in the future. Cash flows from operations are primarily driven by crude oil production, commodity prices and settlements of our commodity derivatives. As a result of the significant decline in crude oil prices, our revenues and thus our cash flows from operations have also declined. However, this decline in our cash flows from operations was partially offset due to the net cash we received from derivative settlements. We currently believe that cash flows from operations and borrowings under our revolving credit facility provide adequate financial flexibility and will be sufficient to fund our immediate cash flow requirements.

• Revolving credit facility. As of July 29, 2016, our revolving credit facility had a borrowing base of $600.0 million, with $60.0 million of borrowings outstanding and $0.4 million in letters of credit issued, which reduce the amounts available under our revolving credit facility. The borrowing base under our revolving credit facility is affected by assumptions with respect to, among other things, future crude oil and natural gas prices, which are determined by the administrative agent of our revolving credit facility. Our borrowing base may decrease if our administrative agent reduces its expectations with respect to future crude oil and natural gas prices from those used to determine our existing borrowing base.

On May 3, 2016, we entered into an amendment to the credit agreement governing our revolving credit facility. See “Note 5. Long-Term Debt” for further details of this amendment. As a result of our Spring 2016 borrowing base redetermination, our borrowing base was reduced from $685.0 million to $600.0 million. The amount we are able to borrow is subject to compliance with the financial covenants and other provisions of the credit agreement governing the revolving credit facility.

• Hedging. To manage our exposure to commodity price risk and to provide a level of certainty in the cash flows to support our drilling and completion capital expenditure plan, we hedge a portion of our forecasted production.

In February 2015, we entered into derivative transactions offsetting our then existing crude oil derivative positions, which locked in $166.4 million of cash flows. As of June 30, 2016, the remaining locked in cash flows from the offsetting derivative transactions was approximately $19.9 million, of which approximately $17.2 million will be received during the remainder of 2016 and approximately $2.7 million will be received in the first quarter of 2017 as the applicable derivative contracts settle.

As of July 29, 2016, we have derivative positions in place for approximately 55% of our estimated crude oil production for the balance of 2016, which is based on the midpoint of our current oil production guidance. The derivative positions for the balance of 2016 consist of 9,750 Bbls/d of crude oil fixed price swaps at a weighted average fixed price of $60.03

-26-

per Bbl and 4,000 Bbls/d of crude oil costless collars at a weighted average floor price of $50.00 per Bbl and a weighted average ceiling price of $76.50 per Bbl. Additionally, for the first half of 2017, we have 12,000 Bbls/d of crude oil fixed price swaps at a weighted average fixed price of $50.13 per Bbl. We have not entered into any new derivative positions subsequent to June 30, 2016. See “Note 9. Derivative Instruments” for additional details of our derivative positions as of June 30, 2016.

If cash flows from operations and borrowings under our revolving credit facility and the other sources of cash described under “—Sources and Uses of Cash” are insufficient to fund the remainder of our 2016 capital expenditure plan, we may need to reduce our capital expenditure plan or seek other financing alternatives. We may not be able to obtain financing needed in the future on terms that would be acceptable to us, or at all. If we cannot obtain adequate financing, we may be required to limit or defer a portion of our remaining 2016 capital expenditure plan, thereby potentially adversely affecting the recoverability and ultimate value of our oil and gas properties. Subject in each case to then existing market conditions and to our then expected liquidity needs, among other factors, we may use a portion of our cash flows from operations, proceeds from asset sales, securities offerings or borrowings to reduce debt prior to scheduled maturities through debt repurchases, either in the open market or in privately negotiated transactions, through debt redemptions or tender offers, or through repayments of bank borrowings.

Contractual Obligations

The following table sets forth estimates of our contractual obligations as of June 30, 2016 (in thousands):

	July - December 2016		2017		2018		2019		2020		2021 and Thereafter		Total

(1) Long-term debt consists of the principal amounts of the 7.50% Senior Notes due 2020, the 6.25% Senior Notes due 2023, other long-term debt due 2028, and borrowings outstanding under our revolving credit facility which matures in 2018.

(2) Cash interest on senior notes and other long-term debt includes cash payments for interest on the 7.50% Senior Notes due 2020, the 6.25% Senior Notes due 2023 and other long-term debt due 2028.

(3) Cash payments for interest on our revolving credit facility were calculated using the weighted average interest rate of the outstanding borrowings under the revolving credit facility as of June 30, 2016 of 2.44%. Commitment fees on our revolving credit facility were calculated based on the unused portion of lender commitments as of June 30, 2016, at the commitment fee rate of 0.500%.

(4) Drilling rig contracts represent gross contractual obligations and accordingly, other joint owners in the properties operated by us will generally be billed for their working interest share of such costs.

(5) Asset retirement obligations and other are based on estimates and assumptions that affect the reported amounts as of June 30, 2016. Certain of such estimates and assumptions are inherently unpredictable and will differ from actual results.

Financing Arrangements

Senior Secured Revolving Credit Facility

We have a senior secured revolving credit facility with a syndicate of banks that, as of June 30, 2016, had a borrowing base of $600.0 million, with $61.0 million of borrowings outstanding with a weighted average interest rate of 2.44% and $0.4 million in letters of credit outstanding. The credit agreement governing our senior secured revolving credit facility provides for interest-only payments until July 2, 2018, when the credit agreement matures and any outstanding borrowings are due. The borrowing base under our credit agreement is subject to regular redeterminations in the Spring and Fall of each year, as well as special redeterminations described in the credit agreement, in each case which may reduce the amount of the borrowing base.

On May 3, 2016, we entered into an amendment to the credit agreement governing the revolving credit facility (the “Eighth Amendment”) which, among other things, (i) replaced the Total Debt to EBITDA ratio covenant with a Total Secured Debt to EBITDA ratio covenant that requires such ratio not to exceed 2.00 to 1.00, (ii) added a covenant requiring a minimum EBITDA to Interest Expense ratio of at least 2.50 to 1.00, and (iii) reduced the Borrowing Base under the credit facility from $685.0 million

-27-

to $600.0 million until the next redetermination thereof. See “Note 5. Long-Term Debt” for additional details of the Eighth Amendment.

See “Note 5. Long-Term Debt” for additional details of the senior secured revolving credit facility including rates of interest on outstanding borrowings, commitment fees on the unused portion of lender commitments, and covenants we are subject to under the terms of the credit agreement.

Critical Accounting Policies

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the periods reported. Certain of such estimates and assumptions are inherently unpredictable and will differ from actual results. We have identified the following critical accounting policies and estimates used in the preparation of our financial statements: use of estimates, oil and gas properties, oil and gas reserve estimates, derivative instruments, income taxes and commitments and contingencies. These policies and estimates are described in “Note 2. Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in our 2015 Annual Report. We evaluate subsequent events through the date the financial statements are issued.

Impairment of Proved Oil and Gas Properties

Capitalized costs, less accumulated amortization and related deferred income taxes, are limited to the “cost center ceiling” equal to (i) the sum of (A) the present value of estimated future net revenues from proved oil and gas reserves, less estimated future expenditures to be incurred in developing and producing the proved reserves computed using a discount factor of 10%, (B) the costs of unproved properties not being amortized, and (C) the lower of cost or estimated fair value of unproved properties included in the costs being amortized; less (ii) related income tax effects. If the net capitalized costs exceed the cost center ceiling, the excess on a pre-tax basis is recognized as an impairment of proved oil and gas properties. An impairment recognized in one period may not be reversed in a subsequent period even if higher crude oil and natural gas prices in the future increase the cost center ceiling applicable to the subsequent period.

The estimated future net revenues used in the cost center ceiling are calculated using the average realized prices for sales of crude oil and natural gas on the first calendar day of each month during the 12-month period prior to the end of the current reporting period (“12-Month Average Realized Price”). Prices are held constant indefinitely and are not changed except where different prices are fixed and determinable from applicable contracts for the remaining term of those contracts. Prices do not include the impact of derivative instruments because we elected not to meet the criteria to qualify our derivative instruments for hedge accounting treatment.

During the second quarter of 2016, we recorded an after-tax impairment in the carrying value of proved oil and gas properties of $128.1 million ($197.1 million pre-tax). The impairment was due primarily to an 8% decrease in the 12-Month Average Realized Price of crude oil from $43.14 per barrel as of March 31, 2016 to $39.84 per barrel as of June 30, 2016. The price decrease was primarily responsible for a negative revision to our proved reserves for the second quarter of 2016 totaling 1.6 MMBoe (1% of December 31, 2015 proved reserves), all which was attributable to proved developed reserves of producing wells with shorter economic lives. There were no proved undeveloped reserve locations that became uneconomic as a result of the decrease in the 12-Month Average Realized price as of June 30, 2016. We do not expect any significant changes to our development plans in the near term as a result of these revisions to proved reserves. For the six months ended June 30, 2016, we have recorded after-tax impairments in the carrying value of proved oil and gas properties of $306.5 million ($471.5 million pre-tax) due primarily to a 16% decrease in the 12-Month Average Realized Price of crude oil from $47.24 per barrel as of December 31, 2015 to $39.84 per barrel as of June 30, 2016.

-28-

The table below presents various pricing scenarios to demonstrate the sensitivity of our June 30, 2016 cost center ceiling to changes in the 12-month average benchmark crude oil and natural gas prices underlying the 12-Month Average Realized Price. The sensitivity analysis is as of June 30, 2016 and, accordingly, does not consider the results of drilling and completion activity, production, changes in oil and gas prices, and changes in development and operating costs occurring subsequent to June 30, 2016 which may require revisions to estimates of proved reserves.

For the third quarter of 2016, we currently estimate an after-tax impairment in the carrying value of proved oil and gas properties of approximately $75.0 million to $175.0 million ($115.4 million to $269.2 million pre-tax). This estimated impairment is primarily due to a forecasted 4% decrease in the 12-Month Average Realized Price of crude oil from $39.84 per barrel as of June 30, 2016 to an estimated $38.28 per barrel as of September 30, 2016 which is based on the average realized price for sales of crude oil on the first calendar day of each month for the first 11 months and an estimate for the twelfth month based on a quoted forward price. We estimate that this price decrease will result in a negative revision to our proved reserves for the third quarter of 2016 totaling 1.2 MMBoe (1% of December 31, 2015 proved reserves), all of which we estimate to be attributable to proved developed reserves of producing wells with shorter economic lives. Further, we estimate that none of our proved undeveloped reserve locations will be uneconomic and would need to be removed from proved reserves based on these estimated prices. Accordingly, we do not expect any changes to our development plans in the near term as a result of these estimated revisions to proved reserves. Further declines in the 12-Month Average Realized Price of crude oil in subsequent quarters may result in additional negative revisions to proved reserves and additional impairments in the carrying value of proved oil and gas properties.

The key factors and assumptions we used to estimate proved reserves and impairments for the third quarter of 2016 include planned drilling and completion activity, forecasted production, oil and gas price differentials and development and production costs. Given the uncertainty associated with these key factors and assumptions, these estimates should not necessarily be construed as indicative of our future results.

Income Taxes

Income taxes are recognized based on earnings reported for tax return purposes in addition to a provision for deferred income taxes. Deferred income taxes are recognized at the end of each reporting period for the future tax consequences of cumulative temporary differences between the tax bases of assets and liabilities and their reported amounts in our financial statements based on existing tax laws and enacted statutory tax rates applicable to the periods in which the temporary differences are expected to affect taxable income. We assess the realizability of our deferred tax assets each period by considering whether it is more likely than not that all or a portion of the deferred tax assets will not be realized. We consider all available evidence (both positive and negative) when determining whether a valuation allowance is required. In making this assessment, we evaluated possible sources of taxable income that may be available to realize the benefit of deferred tax assets, including projected future taxable income, the reversal of existing temporary differences, taxable income in carryback years and available tax planning strategies.

-29-

A significant item of objective negative evidence considered was the cumulative historical three year pre-tax loss and a net deferred tax asset position at June 30, 2016, driven primarily by the impairments of proved oil and gas properties recognized during the second half of 2015 and the first half of 2016, which limits the ability to consider other subjective evidence such as our potential for future growth. In addition, we also expect to recognize an additional impairment of our proved oil and gas properties during the third quarter of 2016. We also have estimated U.S. federal net operating loss carryforwards of $516.4 million as of June 30, 2016. As a result of the historical and projected future losses, we concluded that it is more likely than not that the deferred tax assets will not be realized and recorded an additional valuation allowance totaling $93.5 million against the net deferred tax assets as of June 30, 2016, reducing the net deferred tax assets to zero.

We will continue to evaluate whether the valuation allowance is needed in future reporting periods. The valuation allowance will remain until we can conclude that the net deferred tax assets are more likely than not to be realized. Future events or new evidence which may lead us to conclude that it is more likely than not our net deferred tax assets will be realized include, but are not limited to, cumulative historical pre-tax earnings, improvements in crude oil prices, and taxable events that could result from one or more transactions. The valuation allowance does not preclude us from utilizing the tax attributes if we recognize taxable income. As long as we conclude that the valuation allowance against net deferred tax assets is necessary, we likely will have no deferred income tax expense or benefit. As a result of the anticipated impairment of proved oil and gas properties in the third quarter of 2016, we expect to record an additional valuation allowance against any deferred tax assets generated by such impairment.

We classify interest and penalties associated with income taxes as interest expense. We follow the tax law ordering approach to determine the sequence in which deferred tax assets and other tax attributes are utilized.

Recently Adopted and Recently Issued Accounting Pronouncements

See “Note 2. Summary of Significant Accounting Policies” for discussion of the accounting pronouncements we recently adopted and the accounting pronouncements recently issued by the FASB.

Volatility of Crude Oil and Natural Gas Prices

Our revenues, future rate of growth, results of operations, financial position and ability to borrow funds or obtain additional capital are substantially dependent upon prevailing prices of crude oil and natural gas, which are affected by changes in market supply and demand, overall economic activity, global political environment, weather, inventory storage levels, basis differentials and other factors, as well as the level and prices at which we have hedged our future production.

We review the carrying value of our oil and gas properties on a quarterly basis using the full cost method of accounting. See “—Critical Accounting Policies—Impairment of Proved Oil and Gas Properties” and “Note 3. Property and Equipment, Net” for additional details.

We use commodity derivative instruments to reduce our exposure to commodity price volatility for a substantial, but varying, portion of our forecasted crude oil and natural gas production and thereby achieve a more predictable level of cash flows to support our drilling and completion capital expenditure plan. We do not enter into derivative instruments for speculative or trading purposes. As of June 30, 2016, our commodity derivative instruments consisted of fixed price swaps, costless collars, and purchased and sold call options. See “Note 9. Derivative Instruments” for further details of our crude oil and natural gas derivative positions as of June 30, 2016.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

For information regarding our exposure to certain market risks, see “Item 7A. Quantitative and Qualitative Disclosures about Market Risk” of our 2015 Annual Report. Except as disclosed in this report, there have been no material changes from the disclosure made in our 2015 Annual Report regarding our exposure to certain market risks.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures. Our Chief Executive Officer and Chief Financial Officer performed an evaluation of our disclosure controls and procedures, which have been designed to provide reasonable assurance that the information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. They concluded that the controls and procedures were effective as of June 30, 2016 to provide reasonable assurance that the information required to be disclosed by the Company in reports it files under the Exchange Act is recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. While our disclosure controls and procedures provide reasonable assurance that the appropriate information will be available on a timely basis, this assurance is subject to limitations inherent in any control system, no matter how well it may be designed or administered.

Changes in Internal Controls. There was no change in our internal control over financial reporting during the quarter ended June 30, 2016 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Nature Of Operations

1. Basis of Presentation

Nature of Operations

Carrizo Oil & Gas, Inc. is a Houston-based energy company which, together with its subsidiaries (collectively, the “Company”), is actively engaged in the exploration, development, and production of oil and gas primarily from resource plays located in the United States. The Company’s current operations are principally focused in proven, producing oil and gas plays primarily in the Eagle Ford Shale in South Texas, the Delaware Basin in West Texas, the Niobrara Formation in Colorado, the Utica Shale in Ohio, and the Marcellus Shale in Pennsylvania.

Consolidated Financial Statements

The accompanying unaudited interim consolidated financial statements include the accounts of the Company after elimination of intercompany transactions and balances and have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) and therefore do not include all disclosures required for financial statements prepared in conformity with accounting principles generally accepted in the U.S. (“GAAP”). In the opinion of management, these financial statements include all adjustments (consisting of normal recurring accruals and adjustments) necessary to present fairly, in all material respects, the Company’s interim financial position, results of operations and cash flows. However, the results of operations for the periods presented are not necessarily indicative of the results of operations that may be expected for the full year. These financial statements and related notes included in this Quarterly Report on Form 10-Q should be read in conjunction with the Company’s audited Consolidated Financial Statements and related notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 (“2015 Annual Report”). Certain reclassifications have been made to prior period amounts to conform to the current period presentation. Such reclassifications had no material impact on prior period amounts.

Accounting Policies [Abstract]

Summary Of Significant Accounting Policies

2. Summary of Significant Accounting Policies

The Company has provided a discussion of significant accounting policies, estimates, and judgments in “Note 2. Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in its 2015 Annual Report. There have been no changes to the Company’s significant accounting policies since December 31, 2015, other than the recently adopted accounting pronouncements described below.

Recently Adopted Accounting Pronouncements

In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17, Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). ASU 2015-17 requires that all deferred tax liabilities and assets, as well as any related valuation allowance, be classified in the balance sheet as noncurrent. Effective January 1, 2016, the Company early adopted ASU 2015-17 which was applied prospectively and therefore the adoption had no impact on the consolidated balance sheet as of December 31, 2015.

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 is to simplify the presentation of debt issuance costs in financial statements by presenting such costs in the balance sheet as a direct deduction from the related debt rather than as an asset. In August 2015, the FASB issued ASU 2015-15, Interest-Imputation of Interest (Subtopic 835-30) (“ASU 2015-15”), which allows debt issuance costs associated with line-of-credit agreements to be deferred and presented as an asset in the balance sheet, subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings. Effective January 1, 2016, the Company adopted ASU 2015-03 and ASU 2015-15 and reclassified $19.7 million of unamortized debt issuance costs related to the Company’s senior notes from long-term assets to long-term debt in the consolidated balance sheet as of December 31, 2015. Debt issuance costs associated with the Company’s revolving credit facility remain classified as a long-term asset in the consolidated balance sheets.

Recently Issued Accounting Pronouncements

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which amends certain aspects of accounting for share-based payment arrangements. ASU 2016-09 revises or provides alternative accounting for the tax impacts of share-based payment arrangements, forfeitures, minimum statutory tax withholdings, and prescribes certain disclosures to be made in the period of adoption. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. The Company is evaluating ASU 2016-09 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which significantly changes accounting for leases by requiring that lessees recognize a right-of-use asset and a related lease liability representing the obligation to make lease payments, for virtually all lease transactions. Additional disclosures about an entity’s lease transactions will also be required. ASU 2016-02 defines a lease as “a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment (an identified asset) for a period of time in exchange for consideration.” ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach. The Company is evaluating ASU 2016-02 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.

In May 2014, the FASB issued ASU No. 2014-09, Revenue From Contracts With Customers (Topic 606) (“ASU 2014-09”), which will require entities to 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. ASU 2014-09 will supersede most current guidance related to revenue recognition when it becomes effective. The new standard also will require expanded disclosures regarding the nature, timing, amount and certainty of revenue and cash flows from contracts with customers. The FASB originally intended ASU 2014-09 to be effective for interim and annual reporting periods beginning after December 15, 2016, and permits adoption through the use of either the full retrospective approach or a modified retrospective approach. In July 2015, the FASB issued an update which delays by one year the effective date of ASU 2014-09 and allows for early adoption as of the original effective date. The Company does not intend to early-adopt ASU 2014-09 and has not determined which transition method it will use. The Company is evaluating ASU 2014-09 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.

As of June 30, 2016 and December 31, 2015, total property and equipment, net consisted of the following:

	June 30, 2016			December 31, 2015
	(In thousands)
Proved properties		$4,330,119			$3,976,511
Accumulated depreciation, depletion and amortization and impairment	(3,187,736		)	(2,607,360		)

Other property and equipment, net	11,475			12,258
Total property and equipment, net		$1,349,467			$1,716,861

Capitalized oil and gas property costs within a cost center are amortized on an equivalent unit-of-production method, converting natural gas to barrels of oil equivalent at the ratio of six thousand cubic feet of natural gas to one barrel of crude oil, which represents their approximate relative energy content. Average depreciation, depletion and amortization (“DD&A”) per Boe of proved properties was $13.41 and $23.81 for the three months ended June 30,2016 and 2015, respectively, and $14.32 and $23.63 for the six months ended June 30,2016 and 2015, respectively.

The Company capitalized internal costs of employee compensation and benefits, including stock-based compensation, directly associated with acquisition, exploration and development activities totaling $1.4 million and $5.1 million for the three months ended June 30,2016 and 2015, respectively, and $5.8 million and $10.9 million for the six months ended June 30,2016 and 2015, respectively.

Unproved properties, not being amortized, include unevaluated leasehold and seismic costs associated with specific unevaluated properties, the cost of exploratory wells in progress and related capitalized interest. The Company capitalized interest costs associated with its unevaluated leasehold and seismic costs and exploratory well costs totaling $4.9 million and $9.0 million for the three months ended June 30,2016 and 2015, respectively, and $10.5 million and $18.7 million for the six months ended June 30,2016 and 2015, respectively.

Impairment of Proved Oil and Gas Properties

Capitalized costs, less accumulated amortization and related deferred income taxes, are limited to the “cost center ceiling” equal to (i) the sum of (A) the present value of estimated future net revenues from proved oil and gas reserves, less estimated future expenditures to be incurred in developing and producing the proved reserves computed using a discount factor of 10%, (B) the costs of unproved properties not being amortized, and (C) the lower of cost or estimated fair value of unproved properties included in the costs being amortized; less (ii) related income tax effects. If the net capitalized costs exceed the cost center ceiling, the excess, on a pre-tax basis, is recognized as an impairment of proved oil and gas properties. An impairment recognized in one period may not be reversed in a subsequent period even if higher crude oil and natural gas prices in the future increase the cost center ceiling applicable to the subsequent period.

The estimated future net revenues used in the cost center ceiling are calculated using the average realized prices for sales of crude oil and natural gas on the first calendar day of each month during the 12-month period prior to the end of the current reporting period (“12-Month Average Realized Price”). Prices are held constant indefinitely and are not changed except where different prices are fixed and determinable from applicable contracts for the remaining term of those contracts. Prices do not include the impact of derivative instruments as the Company elected not to meet the criteria to qualify our derivative instruments for hedge accounting treatment.

In the second quarter of 2016, the Company recorded an after-tax impairment in the carrying value of proved oil and gas properties of $128.1 million ($197.1 million pre-tax). The impairment was due primarily to an 8% decrease in the 12-Month Average Realized Price of crude oil from $43.14 per barrel as of March 31, 2016 to $39.84 per barrel as of June 30, 2016. For the six months ended June 30,2016, the Company recorded after-tax impairments in the carrying value of proved oil and gas properties of $306.5 million ($471.5 million pre-tax) due primarily to a 16% decrease in the 12-Month Average Realized Price of crude oil from $47.24 per barrel as of December 31, 2015 to $39.84 per barrel as of June 30, 2016. There were no impairments of proved oil and gas properties for the three and six months ended June 30,2015.

The Company expects to record an impairment in the carrying value of proved oil and gas properties in the third quarter of 2016. This estimated impairment is primarily due to a forecasted 4% decrease in the 12-Month Average Realized Price of crude oil from $39.84 per barrel as of June 30, 2016 to $38.28 per barrel as of September 30, 2016, which is based on the average realized price for sales of crude oil on the first calendar day of each month for the first 11 months and an estimate for the twelfth month based on a quoted forward price. Further declines in the 12-Month Average Realized Price of crude oil in subsequent quarters may result in additional impairments in the carrying value of proved oil and gas properties.

Income Taxes

4. Income Taxes

The Company’s estimated annual effective income tax rates are used to allocate expected annual income tax expense or benefit to interim periods. The rates are the ratio of estimated annual income tax expense or benefit to estimated annual income or loss before income taxes by taxing jurisdiction, except for discrete items, which are significant, unusual or infrequent items for which income taxes are computed and recorded in the interim period in which the discrete item occurs. The estimated annual effective income tax rates are applied to the year-to-date income or loss before income taxes by taxing jurisdiction to determine the income tax expense or benefit allocated to the interim period. The Company updates its estimated annual effective income tax rates on a quarterly basis considering the geographic mix of income or loss attributable to the tax jurisdictions in which the Company operates.

The Company’s income tax (expense) benefit from continuing operations differs from the income tax (expense) benefit computed by applying the U.S. federal statutory corporate income tax rate of 35% to loss from continuing operations before income taxes as follows:

	Three Months Ended June 30,						Six Months Ended June 30,

Deferred Tax Assets Valuation Allowance

Deferred tax assets are recorded for net operating losses and temporary differences between the book and tax basis of assets and

liabilities expected to produce tax deductions in future periods. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those deferred tax assets would be deductible. The Company assesses the realizability of its deferred tax assets each period by considering whether it is more likely than not that all or a portion of the deferred tax assets will not be realized. The Company considers all available evidence (both positive and negative) when determining whether a valuation allowance is required. In making this assessment, the Company evaluated possible sources of taxable income that may be available to realize the deferred tax assets, including projected future taxable income, the reversal of existing temporary differences, taxable income in carryback years and available tax planning strategies.

A significant item of objective negative evidence considered was the cumulative historical three year pre-tax loss and a net deferred tax asset position at June 30, 2016, driven primarily by the impairments of proved oil and gas properties recognized during the second half of 2015 and the first half of 2016, which limits the ability to consider other subjective evidence such as the Company’s potential for future growth. The Company has concluded that it is more likely than not the net deferred tax assets will not be realized and recorded an additional valuation allowance totaling $93.5 million against the net deferred tax assets as of June 30, 2016, reducing the net deferred tax assets to zero.

The Company will continue to evaluate whether the valuation allowance is needed in future reporting periods. The valuation allowance will remain until the Company can conclude that the net deferred tax assets are more likely than not to be realized. Future events or new evidence which may lead the Company to conclude that it is more likely than not its net deferred tax assets will be realized include, but are not limited to, cumulative historical pre-tax earnings, improvements in crude oil prices, and taxable events that could result from one or more transactions. The valuation allowance does not preclude the Company from utilizing the tax attributes if the Company recognizes taxable income. As long as the Company concludes that the valuation allowance against net deferred tax assets is necessary, the Company likely will have no deferred income tax expense or benefit.

Senior Secured Revolving Credit Facility

The Company has a senior secured revolving credit facility with a syndicate of banks that, as of June 30, 2016, had a borrowing base of $600.0 million, with $61.0 million of borrowings outstanding with a weighted average interest rate of 2.44%. As of June 30, 2016, the Company also had $0.4 million in letters of credit outstanding, which reduce the amounts available under the revolving credit facility. The credit agreement governing the revolving credit facility provides for interest-only payments until July 2, 2018, when the credit agreement matures and any outstanding borrowings are due. The borrowing base under the credit agreement is subject to regular redeterminations in the Spring and Fall of each year, as well as special redeterminations described in the credit agreement, in each case which may reduce the amount of the borrowing base. The amount the Company is able to borrow with respect to the borrowing base is subject to compliance with the financial covenants and other provisions of the credit agreement. Each of the capitalized terms which are not defined in this note shall have the meaning given to such terms in the credit agreement.

On May 3, 2016, the Company entered into an amendment to the credit agreement (the “Eighth Amendment”) to, among other things (i) replace the Total Debt to EBITDA ratio covenant with a Total Secured Debt to EBITDA ratio covenant that requires such ratio not to exceed 2.00 to 1.00, (ii) add a covenant requiring a minimum EBITDA to Interest Expense ratio of at least 2.50 to 1.00, (iii) reduce the Borrowing Base under the credit facility from $685.0 million to $600.0 million until the next redetermination thereof, (iv) increase the required mortgage coverage on the total value of the oil and gas properties included in the Company’s most recent reserve report from 80% to 90%, (v) require that the Company’s deposit accounts and securities accounts (subject to certain exclusions) become subject to control agreements, (vi) limit the amount of additional senior notes that can be issued by the Company to $400.0 million, (vii) restrict the Company from making borrowings under the credit facility if the Company has or, after giving effect to the borrowing, will have a Consolidated Cash Balance in excess of $50.0 million, (viii) require mandatory prepayment of borrowings to the extent the Consolidated Cash Balance exceeds $50.0 million if either (a) the Company’s ratio of Total Debt to EBITDA exceeds 3.50 to 1.00 or (b) the availability under the credit facility is equal to or less than 20% of the then effective Borrowing Base, (ix) increase the margin on all loans by 0.50%, and (x) increase the commitment fee from 0.375% to 0.50% when utilization of lender commitments is less than 50%.

The obligations of the Company under the credit agreement are guaranteed by the Company’s material domestic subsidiaries and are secured by liens on substantially all of the Company’s assets, including a mortgage lien on oil and gas properties having at least 90% of the proved reserve value of the oil and gas properties included in the determination of the borrowing base.

Borrowings outstanding under the credit agreement bear interest at the Company’s option at either (i) a base rate for a base rate loan plus the margin set forth in the table below, where the base rate is defined as the greatest of the prime rate, the federal funds rate plus 0.50% and the adjusted LIBO rate plus 1.00%, or (ii) an adjusted LIBO rate for a Eurodollar loan plus the margin set forth in the table below. The Company also incurs commitment fees as set forth in the table below based on the unused portion of lender commitments, which are included in interest expense, net.

Ratio of Outstanding Borrowings and Letters of Credit to Lender Commitments	Applicable Margin for Base Rate Loans	Applicable Margin for Eurodollar Loans	Commitment Fee
Less than 25%	1.00%	2.00%	0.500%
Greater than or equal to 25% but less than 50%	1.25%	2.25%	0.500%
Greater than or equal to 50% but less than 75%	1.50%	2.50%	0.500%
Greater than or equal to 75% but less than 90%	1.75%	2.75%	0.500%
Greater than or equal to 90%	2.00%	3.00%	0.500%

As discussed above, the Company is subject to certain covenants under the terms of the credit agreement, which include the maintenance of the following financial covenants determined as of the last day of each quarter: (1) a ratio of Total Secured Debt to EBITDA of not more than 2.00 to 1.00; (2) a Current Ratio of not less than 1.00 to 1.00; and (3) a ratio of EBITDA to Interest Expense of not less than 2.50 to 1.00. As defined in the credit agreement, Total Secured Debt excludes debt issuance costs, EBITDA includes the last four quarters after giving pro forma effect to EBITDA for material acquisitions and dispositions of oil and gas properties, Interest Expense is comprised of the aggregate interest expense paid in cash for the last four quarters, and the Current Ratio includes an add back of the unused portion of lender commitments. As of June 30, 2016, the ratio of Total Secured Debt to EBITDA was 0.15 to 1.00, the Current Ratio was 3.23 to 1.00 and the ratio of EBITDA to Interest Expense was 4.60 to 1.00. Because the financial covenants are determined as of the last day of each quarter, the ratios can fluctuate significantly period to period as the level of borrowings outstanding under the credit agreement are impacted by the timing of cash flows from operations, capital expenditures, acquisitions and dispositions of oil and gas properties and securities offerings.

The credit agreement also places restrictions on the Company and certain of its subsidiaries with respect to additional indebtedness, liens, dividends and other payments to shareholders, repurchases or redemptions of the Company’s common stock, redemptions of senior notes, investments, acquisitions, mergers, asset dispositions, transactions with affiliates, hedging transactions and other matters. Further, the credit agreement restricts the Company from making borrowings under the credit facility if the Company has or, after giving effect to the borrowing, will have a cash balance that exceeds $50.0 million and requires mandatory prepayment of borrowings to the extent the cash balance is in excess of $50.0 million under certain circumstances as described above.

The credit agreement is subject to customary events of default, including in connection with a change in control. If an event of default occurs and is continuing, the lenders may elect to accelerate amounts due under the credit agreement (except in the case of a bankruptcy event of default, in which case such amounts will automatically become due and payable).

Earnings Per Share

8. Earnings Per Share

Basic loss from continuing operations per common share is based on the weighted average number of shares of common stock outstanding during the period. Diluted loss from continuing operations per common share is based on the weighted average number of common shares and all potentially dilutive common shares outstanding during the period which include restricted stock awards and units, performance share awards, stock options and warrants. The Company includes the number of restricted stock awards and units, stock options and warrants in the calculation of diluted weighted average shares outstanding when the grant date or exercise prices are less than the average market prices of the Company’s common stock for the period. The Company includes the number of performance share awards in the calculation of diluted weighted average common shares outstanding based on the number of shares, if any, that would be issuable as if the end of the period was the end of the performance period. When a loss from continuing operations exists, all potentially dilutive common shares outstanding are anti-dilutive and therefore excluded from the calculation of diluted weighted average shares outstanding.

Supplemental loss from continuing operations per common share information is provided below:

Derivative Instruments

9. Derivative Instruments

The Company uses commodity derivative instruments to reduce its exposure to commodity price volatility for a substantial, but varying, portion of its forecasted crude oil and natural gas production and thereby achieve a more predictable level of cash flows to support the Company’s drilling and completion capital expenditure program. The Company does not enter into derivative instruments for speculative or trading purposes. As of June 30, 2016, the Company’s commodity derivative instruments consisted of fixed price swaps, costless collars, and purchased and sold call options, which are described below.

Fixed Price Swaps: The Company receives a fixed price and pays a variable market price to the counterparties over specified periods for contracted volumes.

Costless Collars: A collar is a combination of options including a purchased put option (fixed floor price) and a sold call option (fixed ceiling price) and allows the Company to benefit from increases in commodity prices up to the fixed ceiling price and protect the Company from decreases in commodity prices below the fixed floor price. At settlement, if the market price is below the fixed floor price or is above the fixed ceiling price, the Company receives the fixed price and pays the market price. If the market price is between the fixed floor price and fixed ceiling price, no payments are due from either party. These contracts were executed contemporaneously with the same counterparties and were premium neutral such that no premiums were paid to or received from the counterparties.

Sold Call Options: These contracts give the counterparties the right, but not the obligation, to buy contracted volumes from the Company over specified periods and prices in the future. At settlement, if the market price exceeds the fixed price of the call option, the Company pays the counterparty the excess. If the market price settles below the fixed price of the call option, no payment is due from either party.

Purchased Call Options: These contracts give the Company the right, but not the obligation, to buy contracted volumes from the counterparties over specified periods and prices in the future. At settlement, if the market price exceeds the fixed price of the call option, the counterparties pay the Company the excess. If the market price settles below the fixed price of the call option, no payment is due from either party. The Company nets its purchased call options with its sold call options for the years 2018 through 2020 in the open crude oil derivative positions table below.

The following sets forth a summary of the Company’s open crude oil derivative positions at average NYMEX prices as of June 30, 2016:

Period	Type of Contract	Crude Oil Volumes (in Bbls/d)	Weighted Average Floor Price ($/Bbl)		Weighted Average Ceiling Price ($/Bbl)

FY 2018	Sold Call Options	33,000		$3.25
FY 2019	Sold Call Options	33,000		$3.25
FY 2020	Sold Call Options	33,000		$3.50

In February 2015, the Company entered into derivative transactions offsetting its then existing crude oil derivative positions covering the periods from March 2015 through December 2016. As a result of the offsetting derivative transactions, the Company locked in $166.4 million of cash flows, of which $9.3 million and $40.0 million were received due to contract settlements during the three months ended June 30,2016 and 2015, respectively, and $27.6 million and $40.0 million were received due to contract settlements during the six months ended June 30,2016 and 2015, respectively. These cash flows are included in the “(Gain) loss on derivatives, net” in the consolidated statements of operations. As of June 30, 2016, the fair value of the remaining locked in cash flows is $19.9 million, all of which is a current asset and is classified as “Derivative assets” in the consolidated balance sheets. The derivative assets associated with the offsetting derivative transactions are not subject to price risk and the locked in cash flows will be received as the applicable contracts settle. The offsetting derivative transactions are not included in the table above.

In February 2016, the Company sold out-of-the-money natural gas call options for the years 2017 through 2020 and used the associated premium value to obtain a higher weighted average fixed price of $50.27 per Bbl on 6,000 Bbls/d of newly executed crude oil fixed price swaps for the first half of 2017. These out-of-the-money natural gas call options and in-the-money crude oil fixed price swaps were executed contemporaneously with the same counterparty, therefore, no cash premiums were paid to or received from the counterparty as the premium value associated with the natural gas call options was immediately applied to the crude oil fixed price swaps.

In March 2016, the Company sold 6,000 Bbls/d of in-the-money crude oil fixed price swaps for the first half of the year 2017 at a weighted average fixed price of $50.00 per Bbl. In order to obtain this higher weighted average fixed price, the Company incurred net premiums of approximately $5.6 million, of which approximately $2.8 million was paid during the second quarter of 2016 with the remaining $2.8 million to be paid during the third quarter of 2016.

For the three months ended June 30,2016 and 2015, the Company recorded in the consolidated statements of operations a loss on derivatives, net of $52.2 million and $12.6 million, respectively. For the six months ended June 30,2016 and 2015, the Company recorded in the consolidated statements of operations a loss on derivatives, net of $41.7 million and a gain on derivatives, net of $13.8 million, respectively.

The Company typically has numerous hedge positions that span several time periods and often result in both fair value asset and liability positions held with that counterparty, which positions are all offset to a single fair value asset or liability at the end of each reporting period, including the deferred premiums associated with its hedge positions. The Company nets its derivative instrument fair values executed with the same counterparty pursuant to ISDA master agreements, which provide for net settlement over the term of the contract and in the event of default or termination of the contract. The fair value of derivative instruments where the Company is in a net asset position with its counterparties as of June 30, 2016 and December 31, 2015 totaled $15.1 million and $119.6 million, respectively, and is summarized by counterparty in the table below:

Counterparty	June 30, 2016		December 31, 2015
Wells Fargo	47	%	35	%
Regions	31	%	9	%
Union Bank	20	%	5	%
Capital One	2	%	1	%
Societe Generale	—	%	37	%
Citibank	—	%	13	%
Total	100	%	100	%

The counterparties to the Company’s derivative instruments are also lenders under the Company’s credit agreement which allows the Company to satisfy any need for margin obligations associated with derivative instruments where the Company is in a net liability position with its counterparties with the collateral securing the credit agreement, thus eliminating the need for independent collateral posting.

Because each of the counterparties have investment grade credit ratings, the Company believes it does not have significant credit risk and accordingly does not currently require its counterparties to post collateral to support the net asset positions of its derivative instruments. As such, the Company is exposed to credit risk to the extent of nonperformance by the counterparties to its derivative instruments. Although the Company does not currently anticipate such nonperformance, it continues to monitor the credit ratings of its counterparties.

Fair Value Disclosures [Abstract]

Fair Value Measurements

10. Fair Value Measurements

Accounting guidelines for measuring fair value establish a three-level valuation hierarchy for disclosure of fair value measurements. The valuation hierarchy categorizes assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. The three levels are defined as follows:

Level 1 – Observable inputs such as quoted prices in active markets at the measurement date for identical, unrestricted assets or liabilities.

Level 2 – Other inputs that are observable directly or indirectly such as quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability.

Level 3 – Unobservable inputs for which there is little or no market data and which the Company makes its own assumptions about how market participants would price the assets and liabilities.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The following tables summarize the location and amounts of the Company’s assets and liabilities measured at fair value on a recurring basis as presented in the consolidated balance sheets as of June 30, 2016 and December 31, 2015. All items included in the tables below are Level 2 inputs within the fair value hierarchy:

Derivative liabilities
Other current liabilities	(28,364		)	28,347			(17		)
Derivative liabilities-non current	(22,313		)	9,665			(12,648		)
Total		$119,550			$—			$119,550

The fair values of the Company’s derivative assets and liabilities are based on a third-party industry-standard pricing model that uses market data obtained from third-party sources, including quoted forward prices for crude oil and natural gas, discount rates and volatility factors. The fair values are also compared to the values provided by the counterparties for reasonableness and are adjusted for the counterparties’ credit quality for derivative assets and the Company’s credit quality for derivative liabilities.

The derivative asset and liability fair values reported in the consolidated balance sheets that pertain to the Company’s derivative instruments are as of a particular point in time and subsequently change as these estimates are revised to reflect actual results, changes in market conditions and other factors. However, the fair value of the net derivative asset attributable to the offsetting crude oil derivative transactions are not subject to price risk as changes in the fair value of the original positions are offset by changes in the fair value of the offsetting positions. The Company typically has numerous hedge positions that span several time periods and often result in both derivative assets and liabilities with the same counterparty, which positions are all offset to a single derivative asset or liability in the consolidated balance sheets, including the deferred premiums associated with its hedge positions. The Company nets the fair values of its derivative assets and liabilities associated with derivative instruments executed with the same counterparty pursuant to ISDA master agreements, which provide for net settlement over the term of the contract and in the event of default or termination of the contract. The Company had no transfers into Level 1 and no transfers into or out of Level 2 for the six months ended June 30,2016 and 2015.

Fair Value of Other Financial Instruments

The Company’s other financial instruments consist of cash and cash equivalents, receivables, payables and long-term debt, which are classified as Level 1 under the fair value hierarchy. The carrying amounts of cash and cash equivalents, receivables, and payables approximate fair value due to the highly liquid or short-term nature of these instruments. The carrying amount of long-term debt under the Company’s revolving credit facility approximates fair value as borrowings bear interest at variable rates. The following table presents the carrying amounts of the Company’s senior notes and other long-term debt, net of debt premiums and debt issuance costs, with the fair values of each based on quoted market prices.

	June 30, 2016				December 31, 2015
	Carrying Amount		Fair Value		Carrying Amount		Fair Value
	(In thousands)
7.50% Senior Notes due 2020		$592,818		$607,500		$592,203		$528,000

Condensed Consolidating Financial Information

11. Condensed Consolidating Financial Information

The rules of the SEC require that condensed consolidating financial information be provided for a subsidiary that has guaranteed the debt of a registrant issued in a public offering, where the guarantee is full, unconditional and joint and several and where the voting interest of the subsidiary is 100% owned by the registrant. The Company is, therefore, presenting condensed consolidating financial information on a parent company, combined guarantor subsidiaries, combined non-guarantor subsidiaries and consolidated basis and should be read in conjunction with the consolidated financial statements. The financial information may not necessarily be indicative of results of operations, cash flows, or financial position had such guarantor subsidiaries operated as independent entities.

Accounting Policies [Abstract]

New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2015-17, Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). ASU 2015-17 requires that all deferred tax liabilities and assets, as well as any related valuation allowance, be classified in the balance sheet as noncurrent. Effective January 1, 2016, the Company early adopted ASU 2015-17 which was applied prospectively and therefore the adoption had no impact on the consolidated balance sheet as of December 31, 2015.

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 is to simplify the presentation of debt issuance costs in financial statements by presenting such costs in the balance sheet as a direct deduction from the related debt rather than as an asset. In August 2015, the FASB issued ASU 2015-15, Interest-Imputation of Interest (Subtopic 835-30) (“ASU 2015-15”), which allows debt issuance costs associated with line-of-credit agreements to be deferred and presented as an asset in the balance sheet, subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings. Effective January 1, 2016, the Company adopted ASU 2015-03 and ASU 2015-15 and reclassified $19.7 million of unamortized debt issuance costs related to the Company’s senior notes from long-term assets to long-term debt in the consolidated balance sheet as of December 31, 2015. Debt issuance costs associated with the Company’s revolving credit facility remain classified as a long-term asset in the consolidated balance sheets.

Recently Issued Accounting Pronouncements

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which amends certain aspects of accounting for share-based payment arrangements. ASU 2016-09 revises or provides alternative accounting for the tax impacts of share-based payment arrangements, forfeitures, minimum statutory tax withholdings, and prescribes certain disclosures to be made in the period of adoption. ASU 2016-09 is effective for interim and annual periods beginning after December 15, 2016, with early adoption permitted. The Company is evaluating ASU 2016-09 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”), which significantly changes accounting for leases by requiring that lessees recognize a right-of-use asset and a related lease liability representing the obligation to make lease payments, for virtually all lease transactions. Additional disclosures about an entity’s lease transactions will also be required. ASU 2016-02 defines a lease as “a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment (an identified asset) for a period of time in exchange for consideration.” ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018 with early adoption permitted. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented in the financial statements using a modified retrospective approach. The Company is evaluating ASU 2016-02 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.

In May 2014, the FASB issued ASU No. 2014-09, Revenue From Contracts With Customers (Topic 606) (“ASU 2014-09”), which will require entities to 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. ASU 2014-09 will supersede most current guidance related to revenue recognition when it becomes effective. The new standard also will require expanded disclosures regarding the nature, timing, amount and certainty of revenue and cash flows from contracts with customers. The FASB originally intended ASU 2014-09 to be effective for interim and annual reporting periods beginning after December 15, 2016, and permits adoption through the use of either the full retrospective approach or a modified retrospective approach. In July 2015, the FASB issued an update which delays by one year the effective date of ASU 2014-09 and allows for early adoption as of the original effective date. The Company does not intend to early-adopt ASU 2014-09 and has not determined which transition method it will use. The Company is evaluating ASU 2014-09 to determine what impact the new standard will have on its consolidated financial statements and related disclosures.
