MARTIN MIDSTREAM PARTNERS L.P.
NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS
(Dollars in thousands, except where otherwise indicated)
June 30, 2015
(Unaudited)




(1)
General

Martin Midstream Partners L.P. (the "Partnership") is a publicly traded limited partnership with a diverse set of operations focused primarily in the United States ("U.S.") Gulf Coast region. Its four primary business lines include:  terminalling and storage services for petroleum products and by-products including the refining of naphthenic crude oil, blending and packaging of finished lubricants; natural gas services, including liquids transportation and distribution services and natural gas storage; sulfur and sulfur-based products processing, manufacturing, marketing and distribution; and marine transportation services for petroleum products and by-products.
 
The Partnership’s unaudited consolidated and condensed financial statements have been prepared in accordance with the requirements of Form 10-Q and United States Generally Accepted Accounting Principles ("U.S. GAAP") for interim financial reporting. Accordingly, these financial statements have been condensed and do not include all of the information and footnotes required by U.S. GAAP for annual audited financial statements of the type contained in the Partnership’s annual reports on Form 10-K. In the opinion of the management of the Partnership’s general partner, all adjustments and elimination of significant intercompany balances necessary for a fair presentation of the Partnership’s financial position, results of operations, and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. Results for such interim periods are not necessarily indicative of the results of operations for the full year. These financial statements should be read in conjunction with the Partnership’s audited consolidated financial statements and notes thereto included in the Partnership’s annual report on Form 10-K for the year ended December 31, 2014, filed with the Securities and Exchange Commission (the "SEC") on March 2, 2015, as amended by Amendment No. 1 on Form 10-K/A for the year ended December 31, 2014 filed on March 5, 2015.

Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these consolidated and condensed financial statements in conformity with U.S. GAAP.  Actual results could differ from those estimates.

New Accounting Pronouncements

In April 2015, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2015-06, Earnings Per Share (Topic 260): Effects on Historical Earnings per Unit of Master Limited Partnership Dropdown Transactions, which requires a master limited partnership ("MLP") to allocate earnings (losses) of a transferred business entirely to the general partner when computing earnings per unit ("EPU") for periods before the dropdown transaction occurred. The EPU for limited partners that was previously reported would not change as a result of the dropdown transaction. The ASU also requires an MLP to disclose the effects of the dropdown transaction on EPU for the periods before and after the dropdown transaction occurred. This ASU is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The ASU requires retrospective application and early adoption is permitted. The Partnership is evaluating the effect that ASU 2015-06 will have on its consolidated and condensed financial statements and related disclosures.

In April 2015, the FASB issued ASU No. 2015-03, Interest-Imputation of Interest, which simplifies presentation of debt issuance costs. The amended guidance requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. Early application is permitted under the retrospective transition method. The Partnership has elected to adopt this guidance effective January 1, 2015. The standard only affects presentation on the Partnership's Consolidated and Condensed Balance Sheets and does not affect any of the Partnership's other financial statements. The amount of debt issuance costs, net of accumulated amortization, from the December 31, 2014 audited balance sheet that were reclassified and shown as a reduction of the related long-term debt balances is $13,118.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. The new standard is effective for the Partnership on January 1, 2018. The standard permits the use of either the retrospective or cumulative effect transition method. The Partnership is evaluating the effect that ASU 2014-09 will have on its consolidated and condensed financial statements and related disclosures. The Partnership has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.

In April 2014, the FASB issued No. ASU 2014-08, Presentation of Financial Statements and Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. The ASU changes the requirements for reporting discontinued operations. A discontinued operation may include a component of an entity or a group of components of an entity, or a business. A disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. Examples include a disposal of a major geographic area, a major line of business or a major equity method investment. Additionally, the update requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income and expenses of discontinued operations. This update has been adopted prospectively for the Partnership's fiscal year beginning January 1, 2015. The adoption did not have a material impact on the Partnership's financial condition, results of operations or cash flows.

Acquisitions
 
Cardinal Gas Storage Partners LLC
On August 29, 2014, the Partnership acquired from Energy Capital Partners ("ECP") all of ECP’s approximate 57.8% Category A membership interest in Cardinal Gas Storage Partners LLC ("Cardinal") for cash consideration of approximately $120,973, subject to certain post-closing adjustments. Prior to the acquisition, the Partnership owned an approximate 42.2% Category A membership interest in Cardinal. Based on the application of purchase accounting, the Partnership reduced the carrying value of its existing investment in Cardinal at the acquisition date by $30,102, which was recognized in the Partnership's Consolidated and Condensed Statements of Operations in the third quarter of 2014. Concurrent with the closing of the transaction, the Partnership retired all of the project level financing of various Cardinal subsidiaries. The Partnership funded the acquisition and repayment of the project financings with borrowings under its revolving credit facility and the use of restricted cash acquired.
The total purchase price is as follows:

Natural Gas Liquids ("NGL") Storage Assets

On May 31, 2014, the Partnership acquired certain NGL storage assets from a subsidiary of Martin Resource Management Corporation ("Martin Resource Management") for $7,388. This acquisition is considered a transfer of net assets between entities under common control. The acquisition of these assets was recorded at the historical carrying value of the assets at the acquisition date. The Partnership recorded the purchase in the following allocation:
Property, plant and equipment
$
2,453

The excess of the purchase price over the carrying value of the assets of $4,948 was recorded as an adjustment to "Partners' capital." This transaction was funded with borrowings under the Partnership's revolving credit facility. As no individual line item of the historical financial statements of the assets was in excess of 3% of the Partnership's relative financial statement captions, the Partnership elected not to retrospectively recast the historical financial information of these assets.

West Texas LPG Pipeline Limited Partnership

On May 14, 2014, the Partnership acquired from a subsidiary of Atlas Pipeline Partners L.P. ("Atlas"), all of the outstanding membership interests in Atlas Pipeline NGL Holdings, LLC and Atlas Pipeline NGL Holdings II, LLC (collectively, "Atlas Holdings") for cash of approximately $134,400. The purchase price was subsequently reduced $501 due to a post-closing working capital adjustment. This transaction was recorded in "Investments in unconsolidated entities" in the Partnership's Consolidated and Condensed Balance Sheet through a purchase price allocation. Atlas Holdings owned a 19.8% limited partnership interest and a 0.2% general partnership interest in West Texas LPG Pipeline L.P. ("WTLPG"). At the time of the purchase, WTLPG was operated by Chevron Pipe Line Company. The 80.0% interest was subsequently sold to ONEOK Partners, L.P. who assumed operational responsibility. WTLPG owns an approximate 2,300 mile common-carrier pipeline system that transports NGLs from New Mexico and Texas to Mont Belvieu, Texas for fractionation. This acquisition will enable the Partnership to participate in the transportation of the growing NGL production of West Texas and other basins along the WTLPG pipeline route. This acquisition of the WTLPG business complements the Partnership's existing East Texas NGL pipeline that delivers Y-grade NGLs from East Texas production areas into Beaumont, Texas on a smaller scale. This transaction was funded with borrowings under the Partnership's revolving credit facility.

Discontinued operations and divestitures

Floating Storage Assets. On February 12, 2015, the Partnership sold all six of its 16,101 barrel liquefied petroleum gas ("LPG") pressure barges, collectively referred to as the "Floating Storage Assets." These assets were acquired on February 28, 2013. On December 19, 2014, the Partnership made the decision to dispose of the Floating Storage Assets. As a result, the Partnership classified the Floating Storage Assets as held for sale at December 31, 2014 and has presented the results of operations and cash flows of the Floating Storage Assets as discontinued operations for the three and six months ended June 30, 2015 and 2014. The Partnership has retrospectively adjusted its prior period consolidated financial statements to comparably classify the amounts related to the operations and cash flows of the Floating Storage Assets as discontinued operations. The Floating Storage Assets were presented as discontinued operations under the guidance prior to the Partnership's adoption of ASU 2014-08 related to discontinued operations. The adoption of the amended guidance was effective for the Partnership January 1, 2015.

The Floating Storage Assets’ operating results, which are included in income from discontinued operations, were as follows:

Investments in Unconsolidated Entities and Joint Ventures

On August 29, 2014, the Partnership acquired ECP’s approximate 57.8% Category A membership interest in Cardinal. Prior to the acquisition, the Partnership owned an approximate 42.2% Category A membership interest in Cardinal which was accounted for by the equity method. See Note 3 for discussion of the acquisition of the remaining membership interests.

On May 14, 2014, the Partnership acquired from a subsidiary of Atlas, all of the outstanding membership interests in Atlas Holdings for cash of approximately $134,400 at closing. The purchase price was subsequently reduced $501 due to a post-closing working capital adjustment. Atlas Holdings owned a 19.8% limited partnership interest and a 0.2% general partnership interest in WTLPG. At the time of the purchase, WTLPG was operated by Chevron Pipe Line Company. The 80% interest was subsequently sold to ONEOK Partners, L.P. who assumed operational responsibility. WTLPG owns an approximate 2,300 mile common-carrier pipeline system that transports NGLs from New Mexico and Texas to Mont Belvieu, Texas for fractionation. The Partnership recognizes its 20% interest in WTLPG as "Investment in unconsolidated entities" on its Consolidated and Condensed Balance Sheets. The Partnership accounts for its ownership interest in WTLPG under the equity method of accounting, with recognition of its ownership interest in the income of WTLPG as "Equity in earnings of unconsolidated entities" on its Consolidated and Condensed Statements of Operations.

During March 2013, the Partnership acquired 100% of the preferred interests in Martin Energy Trading LLC ("MET"), a subsidiary of Martin Resource Management, for $15,000. On August 31, 2014, MET converted its preferred equity to

subordinated debt. The resulting $15,000 note receivable from MET bears an annual interest rate of 15% and matures August 31, 2026. MET may prepay any or all of the note balance on or after September 1, 2016. See Note 12.

Derivative Instruments and Hedging Activities

The Partnership’s revenues and cost of products sold are materially impacted by changes in crude oil, natural gas and NGL prices. Additionally, the Partnership's results of operations are materially impacted by changes in interest rates. In an effort to manage its exposure to these risks, the Partnership periodically enters into various derivative instruments, including commodity and interest rate hedges. The Partnership is required to recognize all derivative instruments as either assets or liabilities at fair value on the Partnership’s Consolidated and Condensed Balance Sheets and to recognize certain changes in the fair value of derivative instruments on the Partnership’s Consolidated and Condensed Statements of Operations.

(a)    Commodity Derivative Instruments

The Partnership from time to time has used derivatives to manage the risk of commodity price fluctuation. Commodity risk is the adverse effect on the value of a liability or future purchase that results from a change in commodity price.  The Partnership has established a hedging policy and monitors and manages the commodity market risk associated with

13
MARTIN MIDSTREAM PARTNERS L.P.
NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS
(Dollars in thousands, except where otherwise indicated)
June 30, 2015
(Unaudited)



potential commodity risk exposure.  In addition, the Partnership has focused on utilizing counterparties for these transactions whose financial condition is appropriate for the credit risk involved in each specific transaction. The Partnership did not have any commodity derivative instruments outstanding during the six months ended June 30, 2015 or 2014.

(b)    Interest Rate Derivative Instruments

The Partnership is exposed to market risks associated with interest rates. Market risk is the adverse effect on the value of a financial instrument that results from a change in interest rates. We minimize this market risk by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken. The Partnership enters into interest rate swaps to manage interest rate risk associated with the Partnership’s variable rate credit facility and its fixed rate senior unsecured notes. All derivatives and hedging instruments are included on the balance sheet as an asset or a liability measured at fair value and changes in fair value are recognized currently in earnings.

During the six months ended June 30, 2015, the Partnership entered into contracts which provided the counterparty the option to enter into swap contracts to hedge the Partnership's exposure to changes in the fair value of its senior unsecured notes
("interest rate swaptions") through June 30, 2015. In connection with the interest rate swaption contracts, the Partnership received premiums of $1,120 and $1,745, which represented their fair value on the date the transactions were initiated and were initially recorded as derivative liabilities on the Partnership's Consolidated and Condensed Balance Sheet, during the three and six months ended June 30, 2015, respectively. Each of the interest rate swaptions was fully amortized as of June 30, 2015. Interest rate swaption contract premiums received are amortized over the period from initiation of the contract through their termination date. For the three and six months ended June 30, 2015, the Partnership recognized $1,120 and $1,745, respectively, of premium in "Interest expense, net" on the Partnership's Consolidated and Condensed Statement of Operations related to the interest rate swaption contracts.

For information regarding gains and losses on interest rate derivative instruments, see "Tabular Presentation of Gains and Losses on Derivative Instruments" below.

Fair Value Measurements

The Partnership follows the provisions of ASC 820 related to fair value measurements and disclosures, which established a framework for measuring fair value and expanded disclosures about fair value measurements. The adoption of this guidance had no impact on the Partnership’s financial position or results of operations.

ASC 820 applies to all assets and liabilities that are being measured and reported on a fair value basis. This statement enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value of each asset and liability carried at fair value into one of the following categories:

Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that are not corroborated by market data.

The fair value of the following items are required to be disclosed on a recurring basis subject to the requirements of ASC 820 at June 30, 2015 and December 31, 2014:

FASB ASC 825-10-65, Disclosures about Fair Value of Financial Instruments, requires that the Partnership disclose estimated fair values for its financial instruments. Fair value estimates are set forth below for the Partnership’s financial instruments. The following methods and assumptions were used to estimate the fair value of each class of financial instrument:

15
MARTIN MIDSTREAM PARTNERS L.P.
NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS
(Dollars in thousands, except where otherwise indicated)
June 30, 2015
(Unaudited)




•
Accounts and other receivables, trade and other accounts payable, accrued interest payable, other accrued liabilities, income taxes payable and due from/to affiliates: The carrying amounts approximate fair value due to the short-term maturity and highly liquid nature of these instruments, and as such these have been excluded from the table above. There is negligible credit risk associated with these instruments.

•
Note receivable and long-term debt including current portion: The carrying amount of the revolving credit facility approximates fair value due to the debt having a variable interest rate and is in Level 2.  The Partnership has not had any indicators which represent a change in the market spread associated with its variable interest rate debt. The estimated fair value of the senior unsecured notes is based on market prices of similar debt. The estimated fair value of the note receivable from Martin Energy Trading was determined by calculating the net present value of the interest payments over the life of the note. The note is considered Level 3 due to the lack of observable inputs for similar transactions between related parties.

     1 Interest rate fluctuates based on the LIBOR rate plus an applicable margin set on the date of each advance. The margin above LIBOR is set every three months. Indebtedness under the credit facility bears interest at LIBOR plus an applicable margin or the base prime rate plus an applicable margin. The applicable margin for revolving loans that are LIBOR loans ranges from 1.75% to 2.75% and the applicable margin for revolving loans that are base prime rate loans ranges from 0.75% to 1.75%.  The applicable margin for existing LIBOR borrowings at June 30, 2015 is 2.75%. The credit facility contains various covenants which limit the Partnership’s ability to make certain investments and acquisitions; enter into certain agreements; incur indebtedness; sell assets; and make certain amendments to the Partnership's omnibus agreement with Martin Resource Management (the "Omnibus Agreement"). The Partnership is permitted to make quarterly distributions so long as no event of default exists.

The Partnership paid cash interest, net of proceeds received from interest rate swaptions, in the amount of $3,015 and $6,735 for the three months ended June 30, 2015 and 2014, respectively.  The Partnership paid cash interest, net of proceeds received from interest rate swaptions, in the amount of $21,104 and $18,424 for the six months ended June 30, and 2014, respectively.  Capitalized interest was $570 and $335 for the three months ended June 30, 2015 and 2014, respectively. Capitalized interest was $1,095 and $723 for the six months ended June 30, 2015 and 2014, respectively.

Partners' Capital

As of June 30, 2015, Partners’ capital consisted of 35,456,862 common limited partner units, representing a 98% partnership interest and a 2% general partner interest. Martin Resource Management, through subsidiaries, owned 6,264,532 of the Partnership's common limited partnership units representing approximately 17.7% of the Partnership's outstanding common limited partnership units. Martin Midstream GP LLC ("MMGP"), the Partnership's general partner, owns the 2% general partnership interest. Martin Resource Management controls the Partnership's general partner, by virtue of its 51% voting interest in MMGP Holdings, LLC ("Holdings"), the sole member of the Partnership's general partner.

The partnership agreement of the Partnership (the "Partnership Agreement") contains specific provisions for the allocation of net income and losses to each of the partners for purposes of maintaining their respective partner capital accounts.

Issuance of Common Units

In March 2014, the Partnership entered into an equity distribution agreement with multiple underwriters (the "Sales Agents") for the ongoing distribution of the Partnership's common units. Pursuant to this program, the Partnership offered and sold common unit equity through the Sales Agents for proceeds of $0 and $17,798 during the six months ended June 30, 2015 and 2014, respectively. The Partnership paid $228 and $382 in equity issuance related costs for the six months ended June 30, 2015 and 2014, respectively. Under the the program, the Partnership issued 0 and 417,156 common units during the six months ended June 30, 2015 and 2014, respectively. Common units issued were at market prices prevailing at the time of the sale. Under the program, the Partnership also received capital contributions from the general partner of $0 and $356 during the six months ended June 30, 2015 and 2014, respectively, to maintain its 2% general partner interest in the Partnership. The net proceeds from the common unit issuances were used to pay down outstanding amounts under the Partnership's revolving credit facility.

Incentive Distribution Rights

MMGP holds a 2% general partner interest and certain incentive distribution rights ("IDRs") in the Partnership. IDRs are a separate class of non-voting limited partner interest that may be transferred or sold by the general partner under the terms of the Partnership Agreement, and represent the right to receive an increasing percentage of cash distributions after the minimum quarterly distribution and any cumulative arrearages on common units once certain target distribution levels have been achieved. The Partnership is required to distribute all of its available cash from operating surplus, as defined in the Partnership Agreement. On October 2, 2012, the Partnership Agreement was amended to provide that the general partner would forego the next $18,000 in incentive distributions that it would otherwise be entitled to receive. Additionally, on May 5, 2014, the owner of our general partner agreed to forego an additional $3,000 in incentive distributions. As of March 31, 2015, all incentive distributions the general partner agreed to forego were satisfied. The general partner received $3,893 and $7,631 in incentive distributions during the three and six months ended June 30, 2015. No incentive distributions were paid to the general partner during the three and six months ended June 30, 2014.
 
The target distribution levels entitle the general partner to receive 2% of quarterly cash distributions up to $0.55 per unit, 15% of quarterly cash distributions in excess of $0.55 per unit until all unitholders have received $0.625 per unit, 25% of quarterly cash distributions in excess of $0.625 per unit until all unitholders have received $0.75 per unit and 50% of quarterly cash distributions in excess of $0.75 per unit.
 
Distributions of Available Cash

The Partnership distributes all of its available cash (as defined in the Partnership Agreement) within 45 days after the end of each quarter to unitholders of record and to the general partner. Available cash is generally defined as all cash and cash equivalents of the Partnership on hand at the end of each quarter less the amount of cash reserves its general partner determines in its reasonable discretion is necessary or appropriate to: (i) provide for the proper conduct of the Partnership’s business; (ii) comply with applicable law, any debt instruments or other agreements; or (iii) provide funds for distributions to unitholders and the general partner for any one or more of the next four quarters, plus all cash on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

Net Income per Unit

The Partnership follows the provisions of the FASB ASC 260-10 related to earnings per share, which addresses the application of the two-class method in determining income per unit for master limited partnerships having multiple classes of securities that may participate in partnership distributions accounted for as equity distributions. Undistributed earnings are allocated to the general partner and limited partners utilizing the contractual terms of the Partnership Agreement. Distributions to the general partner pursuant to the IDRs are limited to available cash that will be distributed as defined in the Partnership Agreement. Accordingly, the Partnership does not allocate undistributed earnings to the general partner for the IDRs because the general partner's share of available cash is the maximum amount that the general partner would be contractually entitled to receive if all earnings for the period were distributed. When current period distributions are in excess of earnings, the excess distributions for the period are to be allocated to the general partner and limited partners based on their respective sharing of income and losses specified in the Partnership Agreement. Additionally, as required under FASB ASC 260-10-45-61A, unvested share-based payments that entitle employees to receive non-forfeitable distributions are considered participating securities, as defined in FASB ASC 260-10-20, for earnings per unit calculations.

For purposes of computing diluted net income per unit, the Partnership uses the more dilutive of the two-class and if-converted methods. Under the if-converted method, the weighted-average number of subordinated units outstanding for the period is added to the weighted-average number of common units outstanding for purposes of computing basic net income per unit and the resulting amount is compared to the diluted net income per unit computed using the two-class method. The following is a reconciliation of net income allocated to the general partner and limited partners for purposes of calculating net income attributable to limited partners per unit:

The weighted average units outstanding for basic net income per unit were 35,307,638 and 35,315,989 for the three and six months ended June 30, 2015, respectively. The weighted average units outstanding for basic net income per unit were 28,923,513 and 27,757,304 for the three and six months ended June 30, 2014, respectively. All outstanding units were included in the computation of diluted earnings per unit and weighted based on the number of days such units were outstanding during the period presented. For diluted net income per unit, the weighted average units outstanding were increased by 68,499 and 56,115 for the three and six months ended June 30, 2015, respectively, due to the dilutive effect of restricted units granted under the Partnership’s long-term incentive plan. For diluted net income per unit, the weighted average units outstanding were increased by 34,233 and 33,350 for the three and six months ended June 30, 2014, respectively, due to the dilutive effect of restricted units granted under the Partnership’s long-term incentive plan.

Related Party Transactions

As of June 30, 2015, Martin Resource Management owned 6,264,532 of the Partnership’s common units representing approximately 17.7% of the Partnership’s outstanding limited partnership units.  Martin Resource Management controls the Partnership's general partner by virtue of its 51% voting interest in Holdings, the sole member of the Partnership's general partner. The Partnership’s general partner, MMGP, owns a 2% general partner interest in the Partnership and the Partnership’s IDRs.  The Partnership’s general partner’s ability, as general partner, to manage and operate the Partnership, and Martin Resource Management’s ownership as of June 30, 2015, of approximately 17.7% of the Partnership’s outstanding limited partnership units, effectively gives Martin Resource Management the ability to veto some of the Partnership’s actions and to control the Partnership’s management.
 
The following is a description of the Partnership’s material related party agreements and transactions:

Related  Party Transactions. The Omnibus Agreement prohibits the Partnership from entering into any material agreement with Martin Resource Management without the prior approval of the Conflicts Committee. For purposes of the Omnibus Agreement, the term "material agreements" means any agreement between the Partnership and Martin Resource Management that requires aggregate annual payments in excess of the then-applicable agreed upon reimbursable amount of indirect general and administrative expenses.

Term and Pricing. The agreement has an initial term that expired in December 2007 but automatically renews for consecutive one year periods unless either party terminates the agreement by giving written notice to the other party at least 30 days prior to the expiration of the then-applicable term.  The Partnership has the right to terminate this agreement at any time by providing 90 days prior notice. These rates are subject to any adjustments which are mutually agreed upon or in accordance with a price index.

Marine Agreements

Marine Transportation Agreement. The Partnership is a party to a marine transportation agreement effective January 1, 2006, as amended, under which the Partnership provides marine transportation services to Martin Resource Management on a spot-contract basis at applicable market rates.  Effective each January 1, this agreement automatically renews for consecutive one year periods unless either party terminates the agreement by giving written notice to the other party at least 60 days prior to the expiration of the then applicable term. The fees the Partnership charges Martin Resource Management are based on applicable market rates.

Marine Fuel.  The Partnership is a party to an agreement with Martin Resource Management dated November 1, 2002, under which Martin Resource Management provides the Partnership with marine fuel from its locations in the Gulf of Mexico at a fixed rate in excess of the Platt’s U.S. Gulf Coast Index for #2 Fuel Oil.  Under this agreement, the Partnership agreed to purchase all of its marine fuel requirements that occur in the areas serviced by Martin Resource Management.

Terminal Services Agreements

Diesel Fuel Terminal Services Agreement.  Effective January 1, 2015, the Partnership entered into a new terminalling services agreement under which the Partnership provides terminal services to Martin Resource Management for marine fuel distribution. This agreement replaced the prior agreement that was in place concerning the same services which was dated October 27, 2004 and consolidated it with the (i) terminalling services agreement entered into in connection with the acquisition of Talen's Marine & Fuel, LLC ("Talen's") and (ii) terminalling services agreement entered into in connection with the acquisition of L&L Holdings LLC ("L&L") into a single agreement. The minimum throughput requirements of the three superseded agreements were aggregated in the new agreement. The per gallon throughput fee the Partnership charges under this agreement may be adjusted annually based on a price index.

Miscellaneous Terminal Services Agreements.  The Partnership is a party to several terminal services agreements and from time to time the Partnership may enter into other terminal service agreements for the purpose of providing terminal services to related parties. Individually, each of these agreements is immaterial but when considered in the aggregate they could be deemed material. These agreements are throughput based with a minimum volume commitment. Generally, the fees due under these agreements are adjusted annually based on a price index.

Other Agreements

 Cross Tolling Agreement. The Partnership is a party to an amended and restated tolling agreement with Cross Oil Refining and Marketing, Inc. ("Cross") dated October 28, 2014, under which the Partnership processes crude oil into finished products, including naphthenic lubricants, distillates, asphalt and other intermediate cuts for Cross.  The tolling agreement expires November 25, 2031.  Under this tolling agreement, Cross agreed to process a minimum of 6,500 barrels per day of crude oil at the facility at a fixed price per barrel.  Any additional barrels are processed at a modified price per barrel.  In addition, Cross agreed to pay a monthly reservation fee and a periodic fuel surcharge fee based on certain parameters specified in the tolling agreement.  All of these fees (other than the fuel surcharge) are subject to escalation annually based upon the greater of 3% or the increase in the Consumer Price Index for a specified annual period.  In addition, on the third, sixth and

ninth anniversaries of the agreement, the parties can negotiate an upward or downward adjustment in the fees subject to their mutual agreement.

Sulfuric Acid Sales Agency Agreement. The Partnership is party to a second amended and restated sulfuric acid sales agency agreement dated August 5, 2013, under which Martin Resource Management purchases and markets the sulfuric acid produced by the Partnership’s sulfuric acid production plant at Plainview, Texas, that is not consumed by the Partnership’s internal operations.  This agreement, as amended, will remain in place until the Partnership terminates it by providing 180 days written notice.  Under this agreement, the Partnership sells all of its excess sulfuric acid to Martin Resource Management. Martin Resource Management then markets such acid to third parties and the Partnership shares in the profit of Martin Resource Management’s sales of the excess acid to such third parties.

Other Miscellaneous Agreements. From time to time, the Partnership enters into other miscellaneous agreements with Martin Resource Management for the provision of other services or the purchase of other goods.

Other Related Party Transactions

As discussed in Note 6, during March 2013, the Partnership acquired 100% of the preferred interests in MET, a subsidiary of Martin Resource Management, for $15,000. On August 31, 2014, MET converted its preferred equity to subordinated debt. The resulting $15,000 note receivable from MET bears an annual interest rate of 15% and matures August 31, 2026. MET may prepay any or all of the note balance on or after September 1, 2016. The note is recorded in "Note receivable - Martin Energy Trading LLC" on the Partnership's Consolidated and Condensed Balance Sheet. Interest income for the three and six months ended June 30, 2015 was $561 and $1,116, respectively, and is included in "Interest expense, net" in the Consolidated and Condensed Statements of Operations.

(13)
Income Taxes

The operations of the Partnership are generally not subject to income taxes because its income is taxed directly to its partners.
    
The Partnership is subject to the Texas margin tax which is included in income tax expense on the Consolidated and Condensed Statements of Operations. The Texas margin tax restructured the state business tax by replacing the taxable capital and earned surplus components of the existing franchise tax with a new "taxable margin" component. Since the tax base on the Texas margin tax is derived from an income-based measure, the margin tax is construed as an income tax and, therefore, the recognition of deferred taxes applies to the margin tax. The impact on deferred taxes as a result of this provision is immaterial.  State income taxes attributable to the Texas margin tax of $314 and $354 were recorded in income tax expense for the three months ended June 30, 2015 and 2014, respectively. State income taxes attributable to the Texas margin tax of $614 and $654 were recorded in income tax expense for the six months ended June 30, 2015 and 2014, respectively.

(14)
Business Segments

The Partnership has four reportable segments: terminalling and storage, natural gas services, sulfur services and marine transportation. The Partnership’s reportable segments are strategic business units that offer different products and

24

(Unaudited)



services. The operating income of these segments is reviewed by the chief operating decision maker to assess performance and make business decisions.

The accounting policies of the operating segments are the same as those described in Note 2 in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 2, 2015, as amended, by Amendment No. 1 on Form 10-K/A filed on March 5, 2015. The Partnership evaluates the performance of its reportable segments based on operating income. There is no allocation of administrative expenses or interest expense.

Unit Based Awards

The Partnership recognizes compensation cost related to unit-based awards to employees in its consolidated financial statements in accordance with certain provisions of ASC 718. The Partnership recognizes compensation costs related to unit-based awards to directors under certain provisions of ASC 505-50-55 related to equity-based payments to non-employees. Amounts recognized in selling, general, and administrative expense in the consolidated and condensed financial statements with respect to these plans are as follows:

Long-Term Incentive Plans
    
      The Partnership's general partner has a long-term incentive plan for employees and directors of the general partner and its affiliates who perform services for the Partnership.
  
The plan consists of two components: restricted units and unit options. The plan currently permits the grant of awards covering an aggregate of 725,000 common units, 241,667 of which may be awarded in the form of restricted units and 483,333 of which may be awarded in the form of unit options. The plan is administered by the compensation committee of the general partner’s board of directors (the "Compensation Committee").
  
Restricted Units.  A restricted unit is a unit that is granted to grantees with certain vesting restrictions. Once these restrictions lapse, the grantee is entitled to full ownership of the unit without restrictions. In addition, the restricted units will

26
MARTIN MIDSTREAM PARTNERS L.P.
NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS
(Dollars in thousands, except where otherwise indicated)
June 30, 2015
(Unaudited)



vest upon a change of control of the Partnership, the general partner or Martin Resource Management or if the general partner ceases to be an affiliate of Martin Resource Management. The Partnership intends the issuance of the common units upon vesting of the restricted units under the plan to serve as a means of incentive compensation for performance and not primarily as an opportunity to participate in the equity appreciation of the common units. Therefore, plan participants will not pay any consideration for the common units they receive, and the Partnership will receive no remuneration for the units. The restricted units issued to directors generally vest in equal annual installments over a four-year period. Restricted units issued to employees generally cliff vest after three years of service.
  
 The restricted units are valued at their fair value at the date of grant which is equal to the market value of common units on such date. A summary of the restricted unit activity for the six months ended June 30, 2015 is provided below:

As of June 30, 2015, there was $2,682 of unrecognized compensation cost related to non-vested restricted units. That cost is expected to be recognized over a weighted-average period of 1.87 years.

In conjunction with restricted unit issuances during the six months ended June 30, 2015, the Partnership received $55 in capital contributions from its general partner to maintain its 2% general partnership interest in the Partnership.

Unit Options.  The plan currently permits the grant of options covering common units. As of June 30, 2015, the Partnership has not granted any common unit options to directors or employees of the Partnership's general partner, or its affiliates. In the future, the Compensation Committee may determine to make grants under the plan to employees and directors containing such terms as the Compensation Committee shall determine. Unit options will have an exercise price that, in the discretion of the Compensation Committee, may not be less than the fair market value of the units on the date of grant. In addition, the unit options will become exercisable upon a change in control of the Partnership's general partner, Martin Resource Management, or if the general partner ceases to be an affiliate of Martin Resource Management or upon the achievement of specified financial objectives.

Condensed Consolidating Financial Information

The Partnership's operations are conducted by its operating subsidiaries as it has no independent assets or operations. Martin Operating Partnership L.P. (the "Operating Partnership"), the Partnership’s wholly-owned subsidiary, and the Partnership's other operating subsidiaries have issued in the past, and may issue in the future, unconditional guarantees of senior

27
MARTIN MIDSTREAM PARTNERS L.P.
NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS
(Dollars in thousands, except where otherwise indicated)
June 30, 2015
(Unaudited)



or subordinated debt securities of the Partnership. The guarantees that have been issued are full, irrevocable and unconditional and joint and several. In addition, the Operating Partnership may also issue senior or subordinated debt securities which, if issued, will be fully, irrevocably and unconditionally guaranteed by the Partnership. Substantially all of the Partnership's operating subsidiaries are subsidiary guarantors of its outstanding senior unsecured notes and any subsidiaries other than the subsidiary guarantors are minor.
    
(17)
Commitments and Contingencies

From time to time, the Partnership is subject to various claims and legal actions arising in the ordinary course of business.  In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Partnership.
    
Pursuant to a Purchase Price Reimbursement Agreement between the Partnership and Martin Resource Management related to the Partnership’s acquisition of the Redbird Gas Storage LLC ("Redbird") Class A interests on October 2, 2012, beginning in the second quarter of 2015, Martin Resource Management will reimburse the Partnership $750 each quarter for four consecutive quarters as a reduction in the purchase price of the Redbird Class A interests.  These payments are a result of Cardinal not achieving certain financial targets set forth in the Purchase Price Reimbursement Agreement.  These payments are considered a reduction of the excess of the purchase price over the carrying value of the assets transferred to the Partnership from Martin Resource Management and will be recorded as an adjustment to "Partners' capital" in each quarter the payments are made. The agreement further provides for purchase price reimbursements of up to $4,500 in 2016 in the event certain financial conditions are not met. Currently, the Partnership has made no determination if the conditions are expected to be met in 2016. For the three and six months ended June 30, 2015, the Partnership received $750 related to the Purchase Price Reimbursement Agreement.

The Partnership has been named as a defendant in a case in Cameron Parish, Louisiana that was served on July 17, 2015. The plaintiff alleges that the Partnership has breached a lease agreement with it by failing to perform work to the property as required under the lease agreement. Prior to this litigation, the Partnership planned to spend $1,600 for such work in 2015. The Partnership intends to vigorously defend this matter and at this time is unable to ascertain the damages, if any, that could ultimately be awarded against it.

(18)
Subsequent Events

Quarterly Distribution. On July 23, 2015, the Partnership declared a quarterly cash distribution of $0.8125 per common unit for the second quarter of 2015, or $3.25 per common unit on an annualized basis, which will be paid on August 14, 2015 to unitholders of record as of August 7, 2015. Additionally, the Partnership expects to pay a distribution to its general partner in the amount of $4,560. Of this amount, $667 is related to the base general partner distribution and $3,893 represents incentive distribution rights paid to the general partner.

Interest Rate Swaps. The Partnership entered into an interest rate swap agreement effective July 2, 2015 with an aggregate notional amount of $200,000 to hedge its exposure to changes in the fair value of its senior unsecured notes.  The termination date of this interest rate swap is July 2, 2020. Under these swap agreements, the Partnership will pay a floating rate of interest and receive a fixed rate based on a three-month U.S. Dollar LIBOR rate to match the fixed rate of the senior unsecured notes. The Partnership will not apply hedge accounting treatment to this instrument. Changes in the fair value of this instrument will be recorded on the Partnership’s Consolidated and Condensed Statements of Operations.

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

References in this quarterly report on Form 10-Q to "Martin Resource Management" refers to Martin Resource Management Corporation and its subsidiaries, unless the context otherwise requires. You should read the following discussion of our financial condition and results of operations in conjunction with the consolidated and condensed financial statements and the notes thereto included elsewhere in this quarterly report.

Forward-Looking Statements

This quarterly report on Form 10-Q includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Statements included in this quarterly report that are not historical facts (including any statements concerning plans and objectives of management for future operations or economic performance, or assumptions or forecasts related thereto), including, without limitation, the information set forth in Management’s Discussion and Analysis of Financial Condition and Results of Operations, are forward-looking statements. These statements can be identified by the use of forward-looking terminology including "forecast," "may," "believe," "will," "expect," "anticipate," "estimate," "continue," or other similar words. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other "forward-looking" information. We and our representatives may from time to time make other oral or written statements that are also forward-looking statements.

These forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.

Because these forward-looking statements involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons, including those discussed under "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2014, filed with the Securities and Exchange Commission (the "SEC") on March 2, 2015, as amended, by Amendment No. 1 on Form 10-K/A for the year ended December 31, 2014 filed on March 5, 2015, and in this report.

Overview
 
We are a publicly traded limited partnership with a diverse set of operations focused primarily in the United States ("U.S.") Gulf Coast region. Our four primary business lines include:

•
Terminalling and storage services for petroleum products and by-products including the refining of naphthenic crude oil, blending and packaging of finished lubricants;

•
Natural gas liquids transportation and distribution services and natural gas storage;

•
Sulfur and sulfur-based products gathering, processing, marketing, manufacturing and distribution; and

•
Marine transportation services for petroleum products and by-products.

The petroleum products and by-products we collect, transport, store and market are produced primarily by major and independent oil and gas companies who often turn to third parties, such as us, for the transportation and disposition of these products. In addition to these major and independent oil and gas companies, our primary customers include independent refiners, large chemical companies, fertilizer manufacturers and other wholesale purchasers of these products. We operate primarily in the U.S. Gulf Coast region. This region is a major hub for petroleum refining, natural gas gathering and processing, and support services for the exploration and production industry.

We were formed in 2002 by Martin Resource Management, a privately-held company whose initial predecessor was incorporated in 1951 as a supplier of products and services to drilling rig contractors. Since then, Martin Resource Management has expanded its operations through acquisitions and internal expansion initiatives as its management identified and capitalized on the needs of producers and purchasers of petroleum products and by-products and other bulk liquids. Martin Resource Management is an important supplier and customer of ours. As of June 30, 2015, Martin Resource Management owned 17.7% of our total outstanding common limited partner units. Furthermore, Martin Resource Management

29

controls Martin Midstream GP LLC ("MMGP"), our general partner, by virtue of its 51% voting interest in MMGP Holdings, LLC ("Holdings"), the sole member of MMGP. MMGP owns a 2.0% general partner interest in us and all of our incentive distribution rights. Martin Resource Management directs our business operations through its ownership interests in and control of our general partner.

We entered into an omnibus agreement dated November 1, 2002, with Martin Resource Management (the "Omnibus Agreement") that governs, among other things, potential competition and indemnification obligations among the parties to the agreement, related party transactions, the provision of general administration and support services by Martin Resource Management and our use of certain of Martin Resource Management’s trade names and trademarks. Under the terms of the Omnibus Agreement, the employees of Martin Resource Management are responsible for conducting our business and operating our assets.

Martin Resource Management has operated our business since 2002.  Martin Resource Management began operating our natural gas services business in the 1950s and our sulfur business in the 1960s. It began our marine transportation business in the late 1980s. It entered into our fertilizer and terminalling and storage businesses in the early 1990s. In recent years, Martin Resource Management has increased the size of our asset base through expansions and strategic acquisitions.

Recent Developments

We believe one of the rationales driving investment in master limited partnerships, including us, is the opportunity for distribution growth offered by the partnerships. Such distribution growth is a function of having access to liquidity in the financial markets used for incremental capital investment (development projects and acquisitions) to grow distributable cash flow.
 
We continually adjust our business strategy to focus on maximizing liquidity, maintaining a stable asset base which generates fee based revenues not sensitive to commodity prices, and improving profitability by increasing asset utilization and controlling costs. Over the past year, we have had access to the capital markets and have appropriate levels of liquidity and operating cash flows to adequately fund our growth.

Disposition of Floating Storage Assets. On February 12, 2015, we sold six liquefied petroleum gas pressure barges (collectively referred to as the "Floating Storage Assets") for $41.3 million. These assets were primarily operated under the floating storage component of our NGL distribution business. The proceeds from the disposition were used to reduce outstanding indebtedness under our revolving credit facility.    

Public Offering. On September 29, 2014, we completed a public offering of 3,450,000 common units at a price of $36.91 per common unit, before the payment of underwriters' discounts, commissions and offering expenses (per unit value is in dollars, not thousands).  Total proceeds from the sale of the 3,450,000 common units, net of underwriters' discounts, commissions and offering expenses, were $122.2 million.  Our general partner contributed $2.6 million in cash to us in conjunction with the issuance in order to maintain its 2.0% general partner interest in us.  All of the net proceeds were used to reduce outstanding indebtedness under our revolving credit facility.

Cardinal Gas Storage. On August 29, 2014, Redbird Gas Storage LLC ("Redbird"), a wholly owned subsidiary of the Partnership, completed the previously announced purchase of all of the outstanding membership interests of Cardinal Gas Storage Partners LLC ("Cardinal") from Energy Capital Partners I, LP, Energy Capital Partners I-A, LP, Energy Capital Partners I-B IP, LP and Energy Capital Partners I (Cardinal IP), LP (together, "ECP") for cash of approximately $121.0 million. Prior to the acquisition, we owned an approximate 42.2% interest in the Category A membership interests in Cardinal. As a result of the acquisition, Redbird owns 100% of the outstanding membership interests in Cardinal. Concurrent with the closing of the transaction, we retired all of the project level financing of various Cardinal subsidiaries. This transaction and repayment of the project financings was funded with borrowings under our revolving credit facility. On October 27, 2014, Cardinal merged with and into Redbird, and Redbird subsequently changed its name to Cardinal.
    
Private Placement of Common Units. On August 29, 2014, we closed a private equity sale with Martin Resource Management, under which Martin Resource Management invested $45.0 million in cash in exchange for 1,171,265 common units (per unit value is in dollars, not thousands). The pricing of $38.42 per common unit was based on the 10-day weighted average price of our common units for the 10 trading days ending August 8, 2014. In connection with the issuance of these common units, our general partner contributed $0.9 million in order to maintain its 2.0% general partner interest in us. All of the net proceeds were used to reduce outstanding indebtedness under our revolving credit facility.

Subsequent Events

Quarterly Distribution.  On July 23, 2015, we declared a quarterly cash distribution of $0.8125 per common unit for the second quarter of 2015, or $3.25 per common unit on an annualized basis, which will be paid on August 14, 2015 to unitholders of record as of August 7, 2015. Additionally, we expect to pay a distribution to our general partner in the amount of $4.6 million. Of this amount, $0.7 million is related to the base general partner distribution and $3.9 million represents incentive distribution rights paid to our general partner.

Interest Rate Swaps. We entered into an interest rate swap agreement effective July 2, 2015 with an aggregate notional amount of $200.0 million to hedge our exposure to changes in the fair value of our senior unsecured notes.  The termination date of this interest rate swap is July 2, 2020. Under these swap agreements, we will pay a floating rate of interest and receive a fixed rate based on a three-month U.S. Dollar LIBOR rate to match the fixed rate of the senior unsecured notes.

Critical Accounting Policies and Estimates    

Our discussion and analysis of our financial condition and results of operations are based on the historical consolidated and condensed financial statements included elsewhere herein. We prepared these financial statements in conformity with United States generally accepted accounting principles ("U.S. GAAP" or "GAAP"). The preparation of these financial statements require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. We routinely evaluate these estimates, utilizing historical experience, consultation with experts and other methods we consider reasonable in the particular circumstances. Our results may differ from these estimates, and any effects on our business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Changes in these estimates could materially affect our financial position, results of operations or cash flows. You should also read Note 2, "Significant Accounting Policies" in Notes to Consolidated Financial Statements included within our Annual Report on Form 10-K for the year ended December 31, 2014. The following table evaluates the potential impact of estimates utilized during the periods ended June 30, 2015 and 2014:

Description
 
Judgments and Uncertainties
 
Effect if Actual Results Differ from Estimates and Assumptions
Allowance for Doubtful Accounts
We evaluate our allowance for doubtful accounts on an ongoing basis and record adjustments when, in management's judgment, circumstances warrant. Reserves are recorded to reduce receivables to the amount ultimately expected to be collected.
 
We evaluate the collectability of our accounts receivable based on factors such as the customer's ability to pay, the age of the receivable and our historical collection experience. A deterioration in any of these factors could result in an increase in the allowance for doubtful accounts balance.
 
If actual collection results are not consistent with our judgments, we may experience an increase in uncollectible receivables. A 10% increase in our allowance for doubtful accounts would not significantly impact net income.
Depreciation
Depreciation expense is computed using the straight-line method over the useful life of the assets.
 
Determination of depreciation expense requires judgment regarding estimated useful lives and salvage values of property, plant and equipment. As circumstances warrant, estimates are reviewed to determine if any changes in the underlying assumptions are needed.
 
The lives of our fixed assets range from 3 - 50 years. If the depreciable lives of our assets were decreased by 10%, we estimate that annual depreciation expense would increase approximately $7.3 million, resulting in a corresponding reduction in net income.
Impairment of Long-Lived Assets

31

We periodically evaluate whether the carrying value of long-lived assets has been impaired when circumstances indicate the carrying value of the assets may not be recoverable. These evaluations are based on undiscounted cash flow projections over the remaining useful life of the asset. The carrying value is not recoverable if it exceeds the sum of the undiscounted cash flows. Any impairment loss is measured as the excess of the asset's carrying value over its fair value.
 
Our impairment analyses require management to use judgment in estimating future cash flows and useful lives, as well as assessing the probability of different outcomes.
 
Applying this impairment review methodology, we recorded no impairment charges during the three and six month periods ended June 30, 2015 and 2014. If actual events are not consistent with our estimates and assumptions change due to new information, we may incur an impairment charge.
Impairment of Goodwill
Goodwill is subject to a fair-value based impairment test on an annual basis, or more frequently if events or changes in circumstances indicate that the fair value of any of our reporting units is less than its carrying amount.
 
We determine fair value using accepted valuation techniques, including discounted cash flow, the guideline public company method and the guideline transaction method. These analyses require management to make assumptions and estimates regarding industry and economic factors, future operating results and discount rates. We conduct impairment testing using present economic conditions, as well as future expectations.
 
We completed the most recent annual review of goodwill as of August 31, 2014 and determined that there was no impairment. Additionally, management is aware of no change in circumstances which indicate a need for an interim impairment evaluation.
Purchase Price Allocations
We allocate the purchase price of an acquired business to its identifiable assets (including identifiable intangible assets) and liabilities based on their fair values at the date of acquisition. Any excess of purchase price in excess of amounts allocated to identifiable assets and liabilities is recorded as goodwill. As additional information becomes available, we may adjust the preliminary allocation for a period of up to one year.
 
The determination of fair values of acquired assets and liabilities requires a significant level of management judgment. Fair values are estimated using various methods as deemed appropriate. For significant transactions, third party assessments may be engaged to assist in the valuation process.
 
If subsequent factors indicate that estimates and assumptions used to allocate costs to acquired assets and liabilities differ from actual results, the allocation between goodwill, other intangible assets and fixed assets could significantly differ. Any such differences could impact future earnings through depreciation and amortization expense. Additionally, if estimated results supporting the valuation of goodwill or other intangible assets are not achieved, impairments could result.
Asset Retirement Obligations
Asset retirement obligations ("AROs") associated with a contractual or regulatory remediation requirement are recorded at fair value in the period in which the obligation can be reasonably estimated and depreciated over the life of the related asset or contractual term. The liability is determined using a credit-adjusted risk-free interest rate and is accreted over time until the obligation is settled.
 
Determining the fair value of AROs requires management judgment to evaluate required remediation activities, estimate the cost of those activities and determine the appropriate interest rate.
 
If actual results differ from judgments and assumptions used in valuing an ARO, we may experience significant changes in ARO balances. The establishment of an ARO has no initial impact on earnings.
Environmental Liabilities
We estimate environmental liabilities using both internal and external resources. Activities include feasibility studies and other evaluations management considers appropriate. Environmental liabilities are recorded in the period in which the obligation can be reasonably estimated.
 
Estimating environmental liabilities requires significant management judgment as well as possible use of third party specialists knowledgeable in such matters.
 
Environmental liabilities have not adversely affected our results of operations or financial condition in the past, and we do not anticipate that they will in the future.

Approval and Review of Related Party Transactions

If we contemplate entering into a transaction, other than a routine or in the ordinary course of business transaction, in which a related person will have a direct or indirect material interest, the proposed transaction is submitted for consideration to the board of directors of our general partner or to our management, as appropriate. If the board of directors of our general partner is involved in the approval process, it determines whether to refer the matter to the Conflicts Committee of our general partner's board of directors, as constituted under our limited partnership agreement. If a matter is referred to the Conflicts Committee, it obtains information regarding the proposed transaction from management and determines whether to engage independent legal counsel or an independent financial advisor to advise the members of the committee regarding the

34

transaction.  If the Conflicts Committee retains such counsel or financial advisor, it considers such advice and, in the case of a financial advisor, such advisor’s opinion as to whether the transaction is fair and reasonable to us and to our unitholders.

How We Evaluate Our Operations

Our management uses a variety of financial and operational measurements other than our financial statements prepared in accordance with U.S. GAAP to analyze our performance. These include: (1) net income before interest expense, income tax expense, and depreciation and amortization ("EBITDA"), (2) adjusted EBITDA and (3) distributable cash flow. Our management views these measures as important performance measures of core profitability for our operations and the ability to generate and distribute cash flow, and as key components of our internal financial reporting. We believe investors benefit from having access to the same financial measures that our management uses.

EBITDA and Adjusted EBITDA. Certain items excluded from EBITDA and adjusted EBITDA are significant components in understanding and assessing an entity's financial performance, such as cost of capital and historical costs of depreciable assets. We have included information concerning EBITDA and adjusted EBITDA because they provide investors and management with additional information to better understand the following: financial performance of our assets without regard to financing methods, capital structure or historical cost basis; our operating performance and return on capital as compared to those of other similarly situated entities; and the viability of acquisitions and capital expenditure projects. Our method of computing adjusted EBITDA may not be the same method used to compute similar measures reported by other entities. The economic substance behind our use of adjusted EBITDA is to measure the ability of our assets to generate cash sufficient to pay interest costs, support our indebtedness and make distributions to our unit holders.

Distributable Cash Flow. Distributable cash flow is a significant performance measure used by our management and by external users of our financial statements, such as investors, commercial banks and research analysts, to compare basic cash flows generated by us to the cash distributions we expect to pay our unitholders. Distributable cash flow is also an important financial measure for our unitholders since it serves as an indicator of our success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not we are generating cash flow at a level that can sustain or support an increase in our quarterly distribution rates. Distributable cash flow is also a quantitative standard used throughout the investment community with respect to publicly-traded partnerships because the value of a unit of such an entity is generally determined by the unit's yield, which in turn is based on the amount of cash distributions the entity pays to a unitholder.

EBITDA, adjusted EBITDA and distributable cash flow should not be considered alternatives to, or more meaningful than, net income, cash flows from operating activities, or any other measure presented in accordance with U.S. GAAP. Our method of computing these measures may not be the same method used to compute similar measures reported by other entities.

Non-GAAP Financial Measures

The following table reconciles the non-GAAP financial measurements used by management to our most directly comparable GAAP measures for the three and six months ended June 30, 2015 and 2014.

Results of Operations

The results of operations for the three and six months ended June 30, 2015 and 2014 have been derived from our consolidated and condensed financial statements.

We evaluate segment performance on the basis of operating income, which is derived by subtracting cost of products sold, operating expenses, selling, general and administrative expenses, and depreciation and amortization expense from revenues.  The following table sets forth our operating revenues and operating income by segment for the three and six months ended June 30, 2015 and 2014.  The results of operations for these interim periods are not necessarily indicative of the results of operations which might be expected for the entire year.

Our consolidated and condensed results of operations are presented on a comparative basis below.  There are certain items of income and expense which we do not allocate on a segment basis.  These items, including equity in earnings (loss) of unconsolidated entities, interest expense, and indirect selling, general and administrative expenses, are discussed following the comparative discussion of our results within each segment.

The three month period ended June 30, 2014 includes equity in earnings of WTLPG from the acquisition in May 2014. The investment was owned for the entire 2015 period.    

On August 29, 2014, the Partnership acquired the approximate 57.8% Category A membership interest in Cardinal it did not previously own. Cardinal results of operations are included in the Natural Gas Services segment subsequent to that date.
    
Equity in earnings of MET, recorded initially in April 2013, represented dividends on our 100% investment in its preferred interests. During March 2013, the Partnership acquired 100% of the preferred interests in MET, a subsidiary of Martin Resource Management, for $15,000. In August, 2014, MET converted its preferred equity to subordinated debt, resulting in a note receivable from MET.

The six month period ended June 30, 2014 includes equity in earnings of WTLPG from the acquisition in May 2014. The investment was owned for the entire 2015 period.    

On August 29, 2014, the Partnership acquired the approximate 57.8% Category A membership interest in Cardinal it did not previously own. Cardinal results of operations are included in the Natural Gas Services segment subsequent to that date.
    
Equity in earnings of MET, recorded initially in April 2013, represented dividends on our 100% investment in its preferred interests. During March 2013, the Partnership acquired 100% of the preferred interests in MET, a subsidiary of Martin Resource Management, for $15,000. In August, 2014, MET converted its preferred equity to subordinated debt, resulting in a note receivable from MET.

Indirect selling, general and administrative expenses decreased for the three months ended June 30, 2015 due to a $0.4 million reduction in acquisition due diligence costs and a $0.2 million decrease in tax fees. These decreases were offset by $0.3 million in higher overhead expenses allocated from Martin Resource Management.

For the six months ended June 30, 2015, the decrease in indirect selling, general and administrative expenses is attributable to lower due diligence costs of $0.8 million and reduced travel and entertainment, professional fees and worker compensation claims of $0.2 million, $0.2 million and $0.1 million, respectively. These decreases are offset by $0.6 million in increased overhead allocated from Martin Resource Management and $0.3 million in higher unit grant compensation expense.

Martin Resource Management allocates to us a portion of its indirect selling, general and administrative expenses for services such as accounting, legal, treasury, clerical, billing, information technology, administration of insurance, engineering,

46

general office expense and employee benefit plans and other general corporate overhead functions we share with Martin Resource Management retained businesses. This allocation is based on the percentage of time spent by Martin Resource Management personnel that provide such centralized services. GAAP also permits other methods for allocation of these expenses, such as basing the allocation on the percentage of revenues contributed by a segment. The allocation of these expenses between Martin Resource Management and us is subject to a number of judgments and estimates, regardless of the method used. We can provide no assurances that our method of allocation, in the past or in the future, is or will be the most accurate or appropriate method of allocation for these expenses. Other methods could result in a higher allocation of selling, general and administrative expense to us, which would reduce our net income.

Under the Omnibus Agreement, we are required to reimburse Martin Resource Management for indirect general and administrative and corporate overhead expenses. The Conflicts Committee of our general partner approved the following reimbursement amounts during the three and six months ended June 30, 2015 and June 30, 2014:

Liquidity and Capital Resources
 
General

Our primary sources of liquidity to meet operating expenses, pay distributions to our unitholders and fund capital expenditures are cash flows generated by our operations and access to debt and equity markets, both public and private.  We have recently completed several transactions that have improved our liquidity position, helping fund our acquisitions and organic growth projects.  

As a result of these financing activities, discussed in further detail below, management believes that expenditures for our current capital projects will be funded with cash flows from operations, current cash balances and our current borrowing capacity under the expanded revolving credit facility. However, it may be necessary to raise additional funds to finance our future capital requirements.

Our ability to satisfy our working capital requirements, to fund planned capital expenditures and to satisfy our debt service obligations will also depend upon our future operating performance, which is subject to certain risks. Please read "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2014, filed with the SEC on March 2, 2015, as amended by Amendment No. 1 on Form 10-K/A filed on March 5, 2015, for a discussion of such risks.

Recent Debt Financing Activity
 
On June 23, 2015, we amended the definition of Consolidated EBITDA (as defined in the credit facility agreement) to include cash interest payments received by the Partnership in respect of subordinated debt owed to the Partnership by MET. Additionally, the amendment permits us to purchase, redeem or otherwise acquire up to $25.0 million of our common units and/or senior unsecured notes, subject to compliance with certain minimum liquidity, maximum leverage and other conditions set forth in the amendment.

Recent Equity Markets Activity

On September 29, 2014, we completed a public offering of 3,450,000 common units at a price of $36.91 per common unit, before the payment of underwriters' discounts, commissions and offering expenses.  Total proceeds from the sale of the 3,450,000 common units, net of underwriters' discounts, commissions and offering expenses, were $122.2 million.  Our general partner contributed $2.6 million in cash to us in conjunction with the issuance in order to maintain its 2.0% general partner interest in us.  The net proceeds from the common unit issuance were used to pay down outstanding amounts under our revolving credit facility.

47


On August 29, 2014, we closed a private equity sale with Martin Resource Management, under which Martin Resource Management invested $45.0 million in cash in exchange for 1,171,265 common units. The pricing of $38.42 per common unit was based on the 10-day weighted average price of our common units for the 10 trading days ending August 8, 2014. In connection with the issuance of these common units, our general partner contributed $0.9 million in order to maintain its 2.0% general partner interest in us. The proceeds from the common unit issuance were used to pay down outstanding amounts under our revolving credit facility.

Due to the foregoing, we believe that cash generated from operations and our borrowing capacity under our credit facility will be sufficient to meet our working capital requirements, anticipated maintenance capital expenditures and scheduled debt payments in 2015.

Finally, our ability to satisfy our working capital requirements, to fund planned capital expenditures and to satisfy our debt service obligations will depend upon our future operating performance, which is subject to certain risks.  Please read "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2014, filed with the SEC on March 2, 2015, as amended by Amendment No. 1 on Form 10-K/A filed on March 5, 2015, for a discussion of such risks.

The change in net cash provided by operating activities for the six months ended June 30, 2015 includes an increase in operating results plus other non-cash items of $27.0 million, a $49.8 million favorable variance in working capital, and an increase in distributions from equity method investees of $3.3 million. Net cash used in discontinued operating activities decreased $3.0 million in 2015.
    
Net cash provided by investing activities for the six months ended June 30, 2015 increased due to a $15.4 million decrease in capital expenditures and plant turnaround costs and $41.3 million in cash proceeds received from the disposition of the Floating Storage Assets. In addition, the $134.4 million investment in WTLPG occurred in the second quarter of 2014.

Net cash used in financing activities for the six months ended June 30, 2015 increased due to $82.2 million of increased net repayments of long-term borrowings and increased cash distributions of $23.4 million. Additionally, proceeds from equity offerings decreased $160.8 million in 2015.

Capital Expenditures and Plant Turnaround Costs

Our operations require continual investment to upgrade or enhance operations and to ensure compliance with safety, operational, and environmental regulations. Our capital expenditures consist primarily of:

•expansion capital expenditures to acquire assets to grow our business, to expand existing facilities, such as projects that increase operating capacity, or to reduce operating costs;
    
•maintenance capital expenditures made to maintain existing assets and operations; and

•plant turnaround costs made at our refinery to perform maintenance, overhaul and repair operations and to inspect, test and replace process materials and equipment.

Expansion capital expenditures were made primarily in our Terminalling and Storage and Natural Gas Services segments during the three and six months ended June 30, 2015. Within our Terminalling and Storage segment, expenditures were made primarily at our Smackover refinery and on certain organic growth projects ongoing in our specialty terminalling operations. Within our Natural Gas Services segment, expenditures were made on ongoing organic growth projects. Maintenance capital expenditures were made primarily in our Terminalling and Storage segment to maintain our existing assets and operations during the three and six months ended June 30, 2015. For the three and six months ended June 30, 2015, plant turnaround costs relate to our Smackover refinery.

Expansion capital expenditures were made primarily in our Terminalling and Storage and Marine Transportation segments during the three and six months ended June 30, 2014. Within our Terminalling and Storage segment, expenditures were made primarily at our Corpus Christi crude terminal, Smackover refinery, and certain smaller organic growth projects ongoing in our specialty terminalling operations. Within our Marine Transportation segment, expenditures were made related to the construction of new barges. Maintenance capital expenditures were made primarily in our Marine Transportation, Terminalling and Storage, and Sulfur Services segments to maintain our existing assets and operations during the three and six months ended June 30, 2014. For the three and six months ended June 30, 2014, plant turnaround costs relate to our Smackover refinery.

Capital Resources

Historically, we have generally satisfied our working capital requirements and funded our capital expenditures with cash generated from operations and borrowings. We expect our primary sources of funds for short-term liquidity will be cash flows from operations and borrowings under our credit facility.

Description of Our Long-Term Debt

2021 Senior Notes

For a description of our 7.250% senior unsecured notes due 2021, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Description of Our Long-Term Debt" in our Annual Report on Form 10-K for the year ended December 31, 2014, as amended.

Revolving Credit Facility

We maintain a $900.0 million credit facility, which was most recently amended on June 23, 2015 to change the definition of Consolidated EBITDA (as defined in the credit facility agreement) to include cash interest payments received by the Partnership in respect of subordinated debt owed to the Partnership by MET. Additionally, the amendment permits us to purchase, redeem or otherwise acquire up to $25.0 million of our common units and/or senior unsecured notes, subject to compliance with certain minimum liquidity, maximum leverage and other conditions set forth in the amendment.

As of June 30, 2015, the capacity of our revolving credit facility is $900.0 million. We had $450.0 million outstanding under the revolving credit facility and $1.6 million of letters of credit issued, leaving a maximum available to be borrowed under our credit facility for future revolving credit borrowings and letters of credit of $448.4 million. Subject to the financial covenants contained in our credit facility and based on our existing EBITDA (as defined in our credit facility) calculations, as of June 30, 2015, we have the ability to borrow approximately $110.6 million of that amount.

The revolving credit facility is used for ongoing working capital needs and general partnership purposes, and to finance permitted investments, acquisitions and capital expenditures.  During the six months ended June 30, 2015, the level of outstanding draws on our credit facility has ranged from a low of $450.0 million to a high of $510.0 million.

The credit facility is guaranteed by substantially all of our subsidiaries. Obligations under the credit facility are secured by first priority liens on substantially all of our assets and those of the guarantors, including, without limitation, inventory, accounts receivable, bank accounts, marine vessels, equipment, fixed assets and the interests in our subsidiaries and certain of our equity method investees.

We may prepay all amounts outstanding under the credit facility at any time without premium or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements. The credit facility requires mandatory prepayments of amounts outstanding thereunder with the net proceeds of certain asset sales, equity issuances and debt incurrences.

Indebtedness under the credit facility bears interest at our option at the Eurodollar Rate (the British Bankers Association LIBOR Rate) plus an applicable margin or the Base Rate (the highest of the Federal Funds Rate plus 0.50%, the 30-day Eurodollar Rate plus 1.0%, or the administrative agent’s prime rate) plus an applicable margin. We pay a per annum fee on all letters of credit issued under the credit facility, and we pay a commitment fee per annum on the unused revolving credit availability under the credit facility. The letter of credit fee, the commitment fee and the applicable margins for our interest rate vary quarterly based on our leverage ratio (as defined in the credit facility, being generally computed as the ratio of total funded debt to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) and are as follows:

The applicable margin for revolving loans that are LIBOR loans ranges from 1.75% to 2.75% and the applicable margin for revolving loans that are base prime rate loans ranges from 0.75% to 1.75%. The applicable margin for LIBOR borrowings at June 30, 2015 is 2.75%.  


50

The credit facility includes financial covenants that are tested on a quarterly basis, based on the rolling four-quarter period that ends on the last day of each fiscal quarter. The maximum permitted leverage ratio is 5.25 to 1.00 with a temporary springing provision to 5.50 to 1.00 under certain scenarios. The maximum permitted senior leverage ratio (as defined in the credit facility but generally computed as the ratio of total secured funded debt to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) is 3.50 to 1.00. The minimum interest coverage ratio (as defined in the credit facility but generally computed as the ratio of consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges to consolidated interest charges) is 2.50 to 1.00.

In addition, the credit facility contains various covenants, which, among other things, limit our and our subsidiaries’ ability to: (i) grant or assume liens; (ii) make investments (including investments in our joint ventures) and acquisitions; (iii) enter into certain types of hedging agreements; (iv) incur or assume indebtedness; (v) sell, transfer, assign or convey assets; (vi) repurchase our equity, make distributions and certain other restricted payments, but the credit facility permits us to make quarterly distributions to unitholders so long as no default or event of default exists under the credit facility; (vii) change the nature of our business; (viii) engage in transactions with affiliates; (ix) enter into certain burdensome agreements; (x) make certain amendments to the Omnibus Agreement and our material agreements; (xi) make capital expenditures; and (xii) permit our joint ventures to incur indebtedness or grant certain liens.

The credit facility contains customary events of default, including, without limitation, (i) failure to pay any principal, interest, fees, expenses or other amounts when due; (ii) failure to meet the quarterly financial covenants; (iii) failure to observe any other agreement, obligation, or covenant in the credit facility or any related loan document, subject to cure periods for certain failures; (iv) the failure of any representation or warranty to be materially true and correct when made; (v) our, or any of our subsidiaries’ default under other indebtedness that exceeds a threshold amount; (vi) bankruptcy or other insolvency events involving us or any of our subsidiaries; (vii) judgments against us or any of our subsidiaries, in excess of a threshold amount; (viii) certain ERISA events involving us or any of our subsidiaries, in excess of a threshold amount; (ix) a change in control (as defined in the credit facility); and (x) the invalidity of any of the loan documents or the failure of any of the collateral documents to create a lien on the collateral.

The credit facility also contains certain default provisions relating to Martin Resource Management. If Martin Resource Management no longer controls our general partner, the lenders under the credit facility may declare all amounts outstanding thereunder immediately due and payable. In addition, an event of default by Martin Resource Management under its credit facility could independently result in an event of default under our credit facility if it is deemed to have a material adverse effect on us.

If an event of default relating to bankruptcy or other insolvency events occurs with respect to us or any of our subsidiaries, all indebtedness under our credit facility will immediately become due and payable. If any other event of default exists under our credit facility, the lenders may terminate their commitments to lend us money, accelerate the maturity of the indebtedness outstanding under the credit facility and exercise other rights and remedies. In addition, if any event of default exists under our credit facility, the lenders may commence foreclosure or other actions against the collateral.
 
As of July 29, 2015, our outstanding indebtedness includes $460.0 million under our credit facility.
 
We are subject to interest rate risk on our credit facility due to the variable interest rate and may enter into interest rate swaps to reduce this variable rate risk.

Seasonality

A substantial portion of our revenues are dependent on sales prices of products, particularly NGLs and fertilizers, which fluctuate in part based on winter and spring weather conditions. The demand for NGLs is strongest during the winter heating season and the refinery blending season. The demand for fertilizers is strongest during the early spring planting season. However, our WTLPG and natural gas storage divisions of the Natural Gas Services segment each provide stable cash flows and are not generally subject to seasonal demand factors. Additionally, our Terminalling and Storage and Marine Transportation segments and the molten sulfur business are typically not impacted by seasonal fluctuations and a significant portion of our net income is derived from our terminalling and storage, sulfur and marine transportation businesses. Therefore, we do not expect that our overall net income will be impacted by seasonality factors.  However, extraordinary weather events, such as hurricanes, have in the past, and could in the future, impact our Terminalling and Storage and Marine Transportation segments.

Impact of Inflation


51

Inflation did not have a material impact on our results of operations for the six months ended June 30, 2015 or 2014.  Although the impact of inflation has been insignificant in recent years, it is still a factor in the U.S. economy and may increase the cost to acquire or replace property, plant and equipment. It may also increase the costs of labor and supplies.  In the future, increasing energy prices could adversely affect our results of operations. Diesel fuel, natural gas, chemicals and other supplies are recorded in operating expenses.  An increase in price of these products would increase our operating expenses which could adversely affect net income. We cannot provide assurance that we will be able to pass along increased operating expenses to our customers.

Environmental Matters

Our operations are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which these operations are conducted. We incurred no material environmental costs, liabilities or expenditures to mitigate or eliminate environmental contamination during the six months ended June 30, 2015 or 2014.

Item 3.
Quantitative and Qualitative Disclosures about Market Risk

Commodity Risk. The Partnership from time to time uses derivatives to manage the risk of commodity price fluctuation. Commodity risk is the adverse effect on the value of a liability or future purchase that results from a change in commodity price.  We have established a hedging policy and monitor and manage the commodity market risk associated with potential commodity risk exposure.  In addition, we focus on utilizing counterparties for these transactions whose financial condition is appropriate for the credit risk involved in each specific transaction.     

Interest Rate Risk. We are exposed to changes in interest rates as a result of our credit facility, which had a weighted-average interest rate of 2.94% as of June 30, 2015.  Based on the amount of unhedged floating rate debt owed by us on June 30, 2015, the impact of a 1% increase in interest rates on this amount of debt would result in an increase in interest expense and a corresponding decrease in net income of approximately $4.5 million annually.

We are not exposed to changes in interest rates with respect to our senior unsecured notes as these obligations are fixed rate.  The estimated fair value of the senior unsecured notes was approximately $395.0 million as of June 30, 2015, based on market prices of similar debt at June 30, 2015.   Market risk is estimated as the potential decrease in fair value of our long-term debt resulting from a hypothetical increase of 1% in interest rates. Such an increase in interest rates would result in approximately a $17.3 million decrease in fair value of our long-term debt at June 30, 2015.

Item 4.
Controls and Procedures

Evaluation of disclosure controls and procedures. In accordance with Rules 13a-15 and 15d-15 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer of our general partner, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer of our general partner concluded that our disclosure controls and procedures were effective, as of the end of the period covered by this report, to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

There were no changes in our internal controls over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
