Organization and Description of Business | |
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, blending and packaging of finished lubricants; natural gas services, including liquids 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 petroleum products and by-products the Partnership collects, transports, stores and distributes are produced primarily by major and independent oil and gas companies who often turn to third parties, such as the Partnership, for the transportation and disposition of these products. In addition to these major and independent oil and gas companies, the Partnership's primary customers include independent refiners, large chemical companies, fertilizer manufacturers and other wholesale purchasers of these products. The Partnership operates primarily in the U.S. Gulf Coast region, which is a major hub for petroleum refining, natural gas gathering and processing and support services for the oil and gas exploration and production industry. | |
In 2011, the Partnership and Martin Resource Management Corporation (“Martin Resource Management” or “Parent”) formed Redbird Gas Storage LLC (“Redbird”), a natural gas storage joint venture to invest in Cardinal Gas Storage Partners LLC (“Cardinal”). Cardinal is a joint venture between Redbird and Energy Capital Partners (“ECP”) that is focused on the development, construction, operation and management of natural gas storage facilities across northern Louisiana and Mississippi. The Partnership now owns 100% of the Class A and Class B equity interests in Redbird. As of December 31, 2013 and 2012, Redbird owned an unconsolidated 42.21% and 41.28% interest in Cardinal, respectively. This investment is accounted for by the equity method. | |
On August 30, 2013, Martin Resource Management completed the sale of a 49% non-controlling voting interest (50% economic interest) in MMGP Holdings, LLC (“Holdings”), a newly-formed sole member of Martin Midstream GP LLC (“MMGP”), the general partner of the Partnership, to certain affiliated investment funds managed by Alinda Capital Partners (“Alinda”).

Significant Accounting Policies | |
(a) Principles of Presentation and Consolidation | |
The consolidated financial statements include the financial statements of the Partnership and its wholly-owned subsidiaries and equity method investees. 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 results of operations, financial position and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. In addition, the Partnership evaluates its relationships with other entities to identify whether they are variable interest entities under certain provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), 810-10 and to assess whether it is the primary beneficiary of such entities. If the determination is made that the Partnership is the primary beneficiary, then that entity is included in the consolidated financial statements in accordance with ASC 810-10. No such variable interest entities exist as of December 31, 2013 or 2012. | |
As discussed in Note 5, on July 31, 2012, the Partnership completed the sale of its East Texas and Northwest Louisiana natural gas gathering and processing assets. These assets, along with additional gathering and processing assets discussed in Note 5 are collectively referred to as the “Prism Assets.” The Partnership has presented the results of operations and cash flows of the Prism Assets as discontinued operations for the years ended December 31, 2012 and 2011. | |
On October 2, 2012, the Partnership, which owned 10.74% of the Class A interests and 100% of the Class B interests, acquired all of the remaining Class A interests in Redbird from Martin Underground Storage, Inc. (“MUS”), a subsidiary of Martin Resource Management. Redbird was formed by the Partnership and Martin Resource Management in 2011 to invest in Cardinal. | |
On October 2, 2012, the Partnership acquired from Cross Oil Refining and Marketing, Inc. (“Cross”), a wholly-owned subsidiary of Martin Resource Management, certain specialty lubricant product blending and packaging assets (“Blending and Packaging Assets”). | |
The acquisitions of the Redbird Class A interests and the Blending and Packaging Assets were considered a transfer of net assets between entities under common control. The acquisitions of the Redbird Class A interests and the Blending and Packaging Assets are recorded at amounts based on the historical carrying value of these assets at October 2, 2012, and the Partnership is required to update its historical financial statements to include the activities of the Redbird Class A interests and the Blending and Packaging Assets as of the date of common control. The Partnership’s accompanying historical financial statements have been retrospectively updated to reflect the effects on financial position, cash flows and results of operations attributable to the activities of the Redbird Class A interests and the Blending and Packaging Assets as if the Partnership owned these assets for the periods presented. Net income attributable to the Redbird Class A interests and the activities of the Blending and Packaging Assets for periods prior to the Partnership’s acquisition of the assets is not allocated to the general and limited partners for purposes of calculating net income per limited partner unit. See Note 16. | |
Certain expense reclassifications were made to the Partnership's Consolidated Statements of Operations for the years ended December 31, 2012 and 2011 in order to conform to the current presentation. | |
(b) Product Exchanges | |
The Partnership enters into product exchange agreements with third parties, whereby the Partnership agrees to exchange natural gas liquids (“NGLs”) and sulfur with third parties. The Partnership records the balance of exchange products due to other companies under these agreements at quoted market product prices and the balance of exchange products due from other companies at the lower of cost or market. Cost is determined using the first-in, first-out (“FIFO”) method. Product exchanges with the same counterparty are entered into in contemplation of one another and are combined. The net amount related to location differentials is reported in “Product sales” or “Cost of products sold” in the Consolidated Statements of Operations. | |
(c) Inventories | |
Inventories are stated at the lower of cost or market. Cost is determined by using the FIFO method for all inventories except lubricants and lubricants packaging inventories. Lubricants and lubricants packaging inventories cost is determined using standard cost, which approximates actual cost, computed on a FIFO basis. | |
(d) Revenue Recognition | |
Terminalling and Storage – Revenue is recognized for storage contracts based on the contracted monthly tank fixed fee. For throughput contracts, revenue is recognized based on the volume moved through the Partnership’s terminals at the contracted rate. For the Partnership’s tolling agreement, revenue is recognized based on the contracted monthly reservation fee and throughput volumes moved through the facility. When lubricants and drilling fluids are sold by truck or rail, revenue is recognized upon delivering product to the customers as title to the product transfers when the customer physically receives the product. | |
Natural Gas Services – NGL distribution revenue is recognized when product is delivered by truck to the Partnership's NGL customers, which occurs when the customer physically receives the product. When product is sold in storage, or by pipeline, the Partnership recognizes NGL distribution revenue when the customer receives the product from either the storage facility or pipeline. | |
Sulfur Services – Revenue from sulfur product sales is recognized when the customer takes title to the product. Revenue from sulfur services is recognized as deliveries are made during each monthly period. | |
Marine Transportation – Revenue is recognized for time charters based on a per day rate. For contracted trips, revenue is recognized upon completion of the particular trip. | |
(e) Equity Method Investments | |
The Partnership uses the equity method of accounting for investments in unconsolidated entities where the ability to exercise significant influence over such entities exists. Investments in unconsolidated entities consist of capital contributions and advances plus the Partnership’s share of accumulated earnings as of the entities’ latest fiscal year-ends, less capital withdrawals and distributions. Investments in excess of the underlying net assets of equity method investees, specifically identifiable to property, plant and equipment, are amortized over the useful life of the related assets. Excess investment representing equity method goodwill is not amortized but is evaluated for impairment, annually. Under certain provisions of ASC 350-20, related to goodwill, this goodwill is not subject to amortization and is accounted for as a component of the investment. Equity method investments are subject to impairment under the provisions of ASC 323-10, which relates to the equity method of accounting for investments in common stock. No portion of the net income from these entities is included in the Partnership’s operating income. | |
In December 2013, Cardinal recorded a $129,384 impairment charge related to long-lived assets of its Monroe Gas Storage Company, LLC ("Monroe"). This amount represents the carrying value of the assets in excess of their fair value. The impairment resulted from the weaker than anticipated results of operations of Monroe. The Partnership's share of this charge was $54,053 and is included in “Equity in loss of unconsolidated entities” in the Consolidated Statement of Operations for the year ended December 31, 2013. The Partnership evaluated its remaining investment in Cardinal and determined that no additional impairment was necessary. | |
The Partnership owns 100% of the Class A and Class B equity interests in Redbird. Redbird, as of December 31, 2013 and 2012, owned a 42.21% and 41.28% interest in Cardinal, respectively. | |
The Partnership owns 100% of the preferred interests in Martin Energy Trading LLC (“MET”), a subsidiary of Martin Resource Management. | |
The Partnership sold its unconsolidated 50% interest in Caliber Gathering, LLC (“Caliber”) during 2013. See Note 10. | |
The Partnership's subsidiary, legal name of Prism Gas Systems I, L.P. (“Prism Gas”), owned unconsolidated 50% interests in three investees, which were sold in 2012. See Note 5. | |
Each of these interests is accounted for under the equity method of accounting. | |
(f) Property, Plant, and Equipment | |
Owned property, plant, and equipment is stated at cost, less accumulated depreciation. Owned buildings and equipment are depreciated using straight-line method over the estimated lives of the respective assets. | |
Equipment under capital leases is stated at the present value of minimum lease payments less accumulated amortization. Equipment under capital leases is amortized on a straight line basis over the estimated useful life of the asset. | |
Routine maintenance and repairs are charged to operating expense while costs of betterments and renewals are capitalized. When an asset is retired or sold, its cost and related accumulated depreciation are removed from the accounts, and the difference between net book value of the asset and proceeds from disposition is recognized as gain or loss. | |
(g) Goodwill and Other Intangible Assets | |
Goodwill is subject to a fair-value based impairment test on an annual basis, or more often if events or circumstances indicate there may be impairment. The Partnership is required to identify its reporting units and determine the carrying value of each reporting unit by assigning the assets and liabilities, including the existing goodwill and intangible assets. The Partnership is required to determine the fair value of each reporting unit and compare it to the carrying amount of the reporting unit. To the extent the carrying amount of a reporting unit exceeds the fair value of the reporting unit, the Partnership would be required to perform the second step of the impairment test, as this is an indication that the reporting unit goodwill may be impaired. | |
All four of the Partnership's “reporting units”, terminalling and storage, natural gas services, sulfur services and marine transportation, contain goodwill. | |
The Partnership has performed the annual impairment tests as of August 31, 2013, 2012, and 2011, and determined fair value in each reporting unit based on the weighted average of two valuation techniques: (i) the discounted cash flow method and (ii) the guideline public company method. At August 31, 2013, 2012, and 2011, the estimated fair value of each of the four reporting units was in excess of its carrying value, resulting in no impairment. | |
No triggering events occurred that would cause the Partnership to perform an impairment test at either December 31, 2013 or 2012. | |
Significant changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit which could give rise to future impairment. Changes to these estimates and assumptions can include, but may not be limited to, varying commodity prices, volume changes and operating costs due to market conditions and/or alternative providers of services. | |
(h) Debt Issuance Costs | |
Debt issuance costs relating to the Partnership’s revolving credit facility and senior unsecured notes are deferred and amortized over the terms of the debt arrangements. | |
In connection with the issuance, amendment, expansion and restatement of debt arrangements, the Partnership incurred debt issuance costs of $9,114, $204 and $3,588 in the years ended December 31, 2013, 2012 and 2011, respectively. | |
Due to a reduction in the number of lenders under the Partnership’s multi-bank credit agreement, $502, $0 and $494 of the existing debt issuance costs were determined not to have continuing benefit and were expensed during 2013, 2012 and 2011, respectively. Remaining unamortized deferred issuance costs are amortized over the term of the revised debt arrangement. | |
Amortization of debt issuance costs, which is included in interest expense, totaled $3,700, $3,290 and $3,755 for the years ended December 31, 2013, 2012 and 2011, respectively. Accumulated amortization amounted to $5,270 and $6,014 at December 31, 2013 and 2012, respectively. | |
(i) Impairment of Long-Lived Assets | |
In accordance with ASC 360-10, long-lived assets, such as property, plant and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet. The Partnership has not identified any triggering events in 2013, 2012 or 2011 that would require an assessment for impairment of long-lived assets. | |
(j) Asset Retirement Obligations | |
Under ASC 410-20, which relates to accounting requirements for costs associated with legal obligations to retire tangible, long-lived assets, the Partnership records an Asset Retirement Obligation (“ARO”) at fair value in the period in which it is incurred by increasing the carrying amount of the related long-lived asset. In each subsequent period, the liability is accreted over time towards the ultimate obligation amount and the capitalized costs are depreciated over the useful life of the related asset. The Partnership’s fixed assets include land, buildings, transportation equipment, storage equipment, marine vessels and operating equipment. | |
(k) Derivative Instruments and Hedging Activities | |
In accordance with certain provisions of ASC 815-10 related to accounting for derivative instruments and hedging activities, all derivatives and hedging instruments are included on the balance sheet as an asset or liability measured at fair value and changes in fair value are recognized currently in earnings unless specific hedge accounting criteria are met. If a derivative qualifies for hedge accounting, changes in the fair value can be offset against the change in the fair value of the hedged item through earnings or recognized in other comprehensive income until such time as the hedged item is recognized in earnings. | |
Derivative instruments not designated as hedges are marked to market with all market value adjustments being recorded in the Consolidated Statements of Operations. As of December 31, 2013, the Partnership did not have any hedging instruments outstanding. Fair value changes associated with the Partnership's hedges have been recorded in accumulated other comprehensive income (“AOCI”) as a component of equity during 2012 and 2011. | |
(l) Comprehensive Income | |
Comprehensive income includes net income and other comprehensive income. Other comprehensive income for the Partnership includes unrealized gains and losses on derivative financial instruments. In accordance with ASC 815-10, the Partnership records deferred hedge gains and losses on its derivative financial instruments that qualify as cash flow hedges as other comprehensive income. | |
(m) Use of Estimates | |
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 financial statements in conformity with accounting principles generally accepted in the U.S. Actual results could differ from those estimates. | |
(n) Indirect Selling, General and Administrative Expenses | |
Indirect selling, general and administrative expenses are incurred by Martin Resource Management and allocated to the Partnership to cover costs of centralized corporate functions such as accounting, treasury, engineering, information technology, risk management and other corporate services. Such expenses are based on the percentage of time spent by Martin Resource Management’s personnel that provide such centralized services. Under an omnibus agreement with Martin Resource Management, the Partnership is required to reimburse Martin Resource Management for indirect general and administrative and corporate overhead expenses. For the years ended December 31, 2013, 2012 and 2011, the conflicts committee of the Partnership's general partner (“Conflicts Committee”) approved reimbursement amounts of $10,621, $7,593 and $4,771, respectively, reflecting the Partnership's allocable share of such expenses. The Conflicts Committee will review and approve future adjustments in the reimbursement amount for indirect expenses, if any, annually. | |
(o) Environmental Liabilities and Litigation | |
The Partnership’s policy is to accrue for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study. Such accruals are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable. | |
(p) Accounts Receivable and Allowance for Doubtful Accounts. | |
Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Partnership’s best estimate of the amount of probable credit losses in the Partnership’s existing accounts receivable. | |
(q) Deferred Catalyst Costs | |
The cost of the periodic replacement of catalysts is deferred and amortized over the catalyst’s estimated useful life, which ranges from 24 to 36 months. | |
(r) Deferred Turnaround Costs | |
The Partnership capitalizes the cost of major turnarounds and amortizes these costs over the estimated period to the next turnaround, which ranges from 24 to 36 months. | |
(s) Income Taxes | |
With respect to the Partnership’s taxable subsidiary (Woodlawn Pipeline Co., Inc.) and the Blending and Packaging Assets prior to the date of acquisition from Cross, income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. | |
As discussed further in Note 19, the assets of the Partnership's taxable subsidiary Woodlawn Pipeline Co., Inc were disposed of on July 31, 2012. The entity was dissolved on December 31, 2012. |

Accounting Changes and Error Corrections [Abstract] | ' |
Recent Accounting Pronouncements | ' |
Recent Accounting Pronouncements | |
In February 2013, the FASB amended the provisions of ASC 220 related to AOCI, which does not change the current requirements for reporting net income or other comprehensive income in financial statements. The standard requires entities to provide information about the amounts reclassified out of AOCI by component. The entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income but only if the amount reclassified is required under United States Generally Accepted Accounting Principles (“U.S. GAAP”) to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. This amended guidance was adopted by the Partnership effective January 1, 2013. As this new guidance only requires enhanced disclosure, adoption did not impact the Partnership's financial position or results of operations. |

As discussed in detail in Note 5, the Partnership sold its 50% interests in Waskom, Matagorda, and PIPE in 2012. The equity in earnings associated with these investments during the periods owned is recorded in income from discontinued operations for the years ended December 31, 2012 and 2011. | ||||||||||||||||||||
On May 1, 2008, certain assets and liabilities were contributed to acquire a 50% ownership interest in Cardinal. In conjunction with this transaction, ECP contributed cash for a 50% ownership interest in Cardinal. | ||||||||||||||||||||
The initial carrying amount of the investment in Cardinal was less than the contributed underlying net assets. Of the basis difference, $1,250 relates to differences in the carrying value of fixed assets contributed as compared to amounts recorded by Cardinal, and is being amortized over 40 years, the approximate useful life of the underlying assets. Such amortization amounted to $31 for each of the three years ending December 31, 2013, 2012 and 2011. The remaining basis difference is a permanent difference that will be realized upon sale of the investment in Cardinal. | ||||||||||||||||||||
On May 24, 2011, Redbird was formed to hold membership interests in Cardinal. On May 27, 2011, initial contributions consisted of all of Martin Resource Management’s membership interests in Cardinal for 100% of the Class A interests in Redbird. Simultaneously, the Partnership acquired 100% of the Class B interests in Redbird for approximately $59,319. Concurrent with the closing of this transaction, Redbird contributed the cash to Cardinal which used the cash, along with a contribution from ECP, to acquire all of the outstanding equity interests in Monroe as well as an option on development rights to an adjacent depleted reservoir facility. As discussed in Notes 2 and 4, on October 2, 2012, the Partnership, acquired the remaining Class A interests in Redbird. As this acquisition is considered a transfer of net assets between entities under common control, the acquisition is recorded at the historical carrying value of these assets at that date. The Partnership is required to retrospectively update its historical financial statements to include the activities of the Class A interests in Redbird as of the date of common control. The Partnership's accompanying historical financial statements for the years ended December 31, 2012 and 2011 have been retrospectively updated to reflect the effects on financial position, cash flows and results of operations attributable to the Redbird Class A interests (including predecessor activities related to the amounts contributed to form Cardinal and Cardinal activities prior to the formation of Redbird) as if the Partnership owned these assets for these periods. | ||||||||||||||||||||
In December 2013, Cardinal recorded a $129,384 impairment charge related to long-lived assets of Monroe. This amount represents the carrying value of the assets in excess of their fair value. The impairment resulted from the weaker than anticipated results of operations of Monroe. The Partnership's share of this charge is $54,053 and is included in “Equity in loss of unconsolidated entities” in the Consolidated Statement of Operations for the year ended December 31, 2013. The Partnership evaluated its remaining investment in Cardinal and determined that no additional impairment was necessary. | ||||||||||||||||||||
As of December 31, 2013, Redbird owned an unconsolidated 42.21% interest in Cardinal. | ||||||||||||||||||||
During March 2013, the Partnership acquired 100% of the preferred interests in MET for $15,000. | ||||||||||||||||||||
During the second quarter of 2012, the Partnership acquired an unconsolidated 50% interest in Caliber and Pecos Valley Producer Services, LLC (“Pecos Valley”). The Partnership sold its interest in Caliber during the fourth quarter of 2013 for $750, resulting in a gain of $750 recorded in other, net in the Partnership's Consolidated Statements of Operations for the year ended December 31, 2013. The Partnership sold its interest in Pecos Valley during the third quarter of 2012 for $531, resulting in a gain of $486 recorded in other, net in the Partnership's Consolidated Statement of Operations for the year ended December 31, 2012. | ||||||||||||||||||||

Fair Value Measurements | ||||||||||||||||
The Partnership uses a valuation framework based upon inputs that market participants use in pricing certain assets and liabilities. These inputs are classified into two categories: observable inputs and unobservable inputs. Observable inputs represent market data obtained from independent sources. Unobservable inputs represent the Partnership's own market assumptions. Unobservable inputs are used only if observable inputs are unavailable or not reasonably available without undue cost and effort. The two types of inputs are further prioritized into the following hierarchy: | ||||||||||||||||
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 reflect the entity's own assumptions and are not corroborated by market data. | ||||||||||||||||
The following items are measured at fair value on a recurring and non-recurring basis at December 31, 2013 and 2012: | ||||||||||||||||

The Partnership is required to disclose estimated fair values for its financial instruments. Fair value estimates are set forth below for these financial instruments. The following methods and assumptions were used to estimate the fair value of each class of financial instrument: | ||||||||||||||||
• | 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 maturity and highly liquid nature of these instruments, and as such these have been excluded from the table above. | |||||||||||||||
• | 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 estimated fair value of the senior unsecured notes is based on market prices of similar debt. The carrying amount of the note payable to bank as of December 31, 2012 is not deemed to be significantly different than the fair value. This note was retired during 2013. |

Derivative Instruments and Hedging Activities | ||||||||||||||||||||||||||||
The Partnership’s results of operations are materially impacted by changes in crude oil, natural gas and NGL prices and 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. | ||||||||||||||||||||||||||||
(a) Commodity Derivative Instruments | ||||||||||||||||||||||||||||
The Partnership has from time to time used derivatives to manage the risk of commodity price fluctuation. The Partnership has established a hedging policy and monitors and manages the commodity market risk associated with potential commodity risk exposure. These hedging arrangements have been in the form of swaps for crude oil, natural gas and natural gasoline. 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. | ||||||||||||||||||||||||||||
Due to the sale of the Prism Assets during 2012, the Partnership terminated and settled all of its commodity derivative instruments during the second quarter of 2012. For the years ended December 31, 2012 and 2011, changes in the fair value of the Partnership’s derivative contracts were recorded in both earnings (income from discontinued operations) and in AOCI as a component of partners’ capital. As of December 31, 2013, the Partnership did not have any commodity derivative instruments outstanding. | ||||||||||||||||||||||||||||
(b) Impact of Commodity Cash Flow Hedges | ||||||||||||||||||||||||||||
Crude Oil. For the years ended December 31, 2012 and 2011, net gains and losses on swap hedge contracts increased crude revenue (included in income from discontinued operations) by $496 and $775, respectively. | ||||||||||||||||||||||||||||
Natural Gas. For the years ended December 31, 2012 and 2011, net gains and losses on swap hedge contracts increased gas revenue (included in income from discontinued operations) by $813 and $332, respectively. | ||||||||||||||||||||||||||||
Natural Gas Liquids. For the years ended December 31, 2012 and 2011, net gains and losses on swap hedge contracts increased liquids revenue (included in income from discontinued operations) by $1,066 and $254, respectively. | ||||||||||||||||||||||||||||
For information regarding fair value amounts and gains and losses on commodity derivative instruments and related hedged items, see “Tabular Presentation of Fair Value Amounts, and Gains and Losses on Derivative Instruments and Related Hedged Items” within this Note. | ||||||||||||||||||||||||||||
(c) Impact of Interest Rate Derivative Instruments | ||||||||||||||||||||||||||||
The Partnership is exposed to market risks associated with interest rates. From time to time, the Partnership enters into interest rate swaps to manage interest rate risk associated with the Partnership’s variable rate debt and term loan credit facilities. As of December 31, 2013, the Partnership did not have any interest rate derivative instruments outstanding. | ||||||||||||||||||||||||||||
In August 2011, the Partnership terminated all of its existing interest swap agreements with an aggregate notional amount of $100,000, which it had entered to hedge its exposure to changes in the fair value of the 2018 senior unsecured notes. These interest rate swap contracts were not designated as fair value hedges and therefore, did not receive hedge accounting but were marked to market through earnings. A termination benefit of $2,800 was received on the early extinguishment of the interest rate swap agreements in August 2011. | ||||||||||||||||||||||||||||
The Partnership recognized increases in interest expense of $0 and $5,779 for the years ended December 31, 2012 and 2011, respectively, related to the difference between the fixed rate and the floating rate of interest on the interest rate swap and net cash settlement of interest rate swaps and hedges. | ||||||||||||||||||||||||||||

Related Party Transactions | ||||||||||||
As of December 31, 2013, Martin Resource Management owned 5,093,267 of the Partnership’s common units representing approximately 19.1% 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 incentive distribution rights (“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 December 31, 2013, of approximately 19.1% 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: | ||||||||||||
Omnibus Agreement | ||||||||||||
Omnibus Agreement. The Partnership and its general partner are parties to 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 the Partnership’s use of certain of Martin Resource Management’s trade names and trademarks. The Omnibus Agreement was amended on November 25, 2009, to include processing crude oil into finished products including naphthenic lubricants, distillates, asphalt and other intermediate cuts.

Services. Under the Omnibus Agreement, Martin Resource Management provides the Partnership with corporate staff, support services, and administrative services necessary to operate the Partnership’s business. The Omnibus Agreement requires the Partnership to reimburse Martin Resource Management for all direct expenses it incurs or payments it makes on the Partnership’s behalf or in connection with the operation of the Partnership’s business. There is no monetary limitation on the amount the Partnership is required to reimburse Martin Resource Management for direct expenses.

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 2.00% to 3.00% and the applicable margin for revolving loans that are base prime rate loans ranges from 1.00% to 2.00%. The applicable margin for LIBOR borrowings at December 31, 2013 is 3.00%. 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 Omnibus Agreement. The Partnership is permitted to make quarterly distributions so long as no event of default exists. | ||||||||
2 Pursuant to the indenture under which the senior notes were issued, the Partnership has the option to redeem up to 35% of the aggregate principal amount at a redemption price of 108.875% of the principal amount, plus accrued and unpaid interest with the proceeds of certain equity offerings. On April 24, 2012, the Partnership notified the trustee of its intention to exercise a partial redemption of the Partnership’s senior notes pursuant to the indenture. On May 24, 2012, the Partnership redeemed $25,000 of the senior notes from various holders using proceeds of the Partnership’s January 2012 follow-on equity offering, which in the interim were used to pay down amounts outstanding under the Partnership’s revolving credit facility. In conjunction with the redemption, the Partnership incurred a debt prepayment premium in the amount of $2,219, which is included in the Consolidated Statement of Operations for the year ended December 31, 2012. | ||||||||
3 Effective March 28, 2013, the Partnership increased the maximum amount of borrowings and letters of credit available under the Credit Facility from $400,000 to $600,000 and extended the maturity date of the facility from April 2016 to March 2018. | ||||||||
4 On February 11, 2013, the Partnership completed a private placement of $250,000 in aggregate principal amount of 7.250% senior unsecured notes due 2021 to qualified institutional buyers under Rule 144A. The Partnership filed with the SEC a registration statement to exchange the 2021 Notes for substantially identical notes that are registered under the Securities Act, and completed the exchange offer on July 31, 2013. | ||||||||
5 The 2018 and 2021 indentures restrict the Partnership’s ability to sell assets; pay distributions or repurchase units or redeem or repurchase subordinated debt; make investments; incur or guarantee additional indebtedness or issue preferred units; and consolidate, merge or transfer all or substantially all of its assets. Many of these covenants will terminate if the notes achieve an investment grade rating from each of Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services and no default (as defined in the indentures) has occurred. | ||||||||
6 In November of 2013, the Partnership retired the capital lease obligations with borrowings under the Partnership's revolving credit facility. In conjunction with the retirement, the Partnership incurred a debt prepayment premium in the amount of $272, which is included in the Consolidated Statement of Operations for the year ended December 31, 2013. | ||||||||
7 In October of 2013, the Partnership retired the note payable to bank with borrowings under the Partnership's revolving credit facility. | ||||||||

As of December 31, 2013, partners’ capital consisted of 26,625,026 common limited partner units, representing a 98% partnership interest and a 2% general partner interest. Martin Resource Management, through subsidiaries, owned 5,093,267 of the Partnership's common limited partnership units representing approximately 19.1% of the Partnership's outstanding common limited partnership units. MMGP, the Partnership's general partner, owns the 2% general partnership interest. | ||||||||||||
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 | ||||||||||||
On November 26, 2012, the Partnership completed a public offering of 3,450,000 common units at a price of $31.16 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 $102,809. The Partnership's general partner contributed $2,194 in cash to the Partnership in conjunction with the issuance in order to maintain its 2% general partner interest in the Partnership. All of the net proceeds were used to reduce outstanding indebtedness of the Partnership. | ||||||||||||
On January 25, 2012, the Partnership completed a public offering of 2,645,000 common units at a price of $36.15 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 2,645,000 common units, net of underwriters’ discounts, commissions and offering expenses were $91,361. The Partnership’s general partner contributed $1,951 in cash to the Partnership in conjunction with the issuance in order to maintain its 2% general partner interest in the Partnership. All of the net proceeds were used to reduce outstanding indebtedness of the Partnership. | ||||||||||||
On February 9, 2011, the Partnership completed a public offering of 1,874,500 common units at a price of $39.35 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 1,874,500 common units, net of underwriters’ discounts, commissions and offering expenses were $70,330. The Partnership’s general partner contributed $1,505 in cash to the Partnership in conjunction with the issuance in order to maintain its 2% general partner interest in the Partnership. All of the net proceeds were used to reduce outstanding indebtedness of the Partnership. | ||||||||||||
Incentive Distribution Rights | ||||||||||||
The Partnership’s general partner, 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 shall forego the next $18,000 in incentive distributions that it would otherwise be entitled to receive. No incentive distributions were allocated to the general partner from July 1, 2012 (which would have been payable to the general partner on November 14, 2012 for the third quarter of 2012 distribution) through December 31, 2013. As of December 31, 2013, the amount of incentive distributions the general partner has foregone is $9,647, resulting in an amount remaining of $8,353. | ||||||||||||
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. | ||||||||||||
For the years ended December 31, 2013, 2012 and 2011, the general partner received $0, $2,857, and $4,901 in incentive distributions. | ||||||||||||
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 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 from continuing operations and net income from discontinued operations allocated to the general partner and limited partners for purposes of calculating net income attributable to limited partners per unit: | ||||||||||||

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. All common unit equivalents were antidilutive for the year ended December 31, 2013 because the limited partners were allocated a net loss in this period. For diluted net income per unit, the weighted average units outstanding were increased by 3,018 and 1,278 for the years ended December 31, 2012 and 2011, respectively, due to the dilutive effect of restricted units granted under the Partnership’s long-term incentive plan. |

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 (“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 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 year ended December 31, 2013 is provided below: | ||||||||||||

Unit Options. The plan currently permits the grant of options covering common units. As of March 3, 2014, 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. |

Income Taxes | ' | |||||||||||
Income Taxes | ||||||||||||
The operations of a partnership are generally not subject to income taxes because its income is taxed directly to its partners, except as discussed below. | ||||||||||||
The activities of the Blending and Packaging Assets prior to the acquisition by the Partnership were subject to federal and state income taxes. Accordingly, income taxes have been included in the Blending and Packaging Assets' operating results from January 1, 2010 through October 2, 2012. Related payables/receivables are included in “Due to affiliates” and “Other current assets”, respectively, in the Consolidated Balance Sheet. | ||||||||||||
Woodlawn, a subsidiary of the Partnership, was subject to income taxes due to its corporate structure. The assets of Woodlawn were sold July 31, 2012 and the corporation was liquidated December 31, 2012. Income tax expense related to Woodlawn is recorded in discontinued operations. A current federal income tax expense of $0, $8,681 and $11, related to the operation of the subsidiary, was recorded for the years ended December 31, 2013, 2012 and 2011, respectively. | ||||||||||||
The Partnership established deferred income taxes of $8,964 associated with book and tax basis differences of the acquired Woodlawn assets and liabilities at the date of acquisition. The basis differences related primarily to property, plant and equipment. A deferred tax benefit of $0, $7,657 and $139 related to the Woodlawn basis differences was recorded for the years ended December 31, 2013, 2012 and 2011, respectively. A deferred tax expense of $0, $402, and $622 related to the Cross basis differences was recorded for the years ended December 31, 2013, 2012 and 2011. No deferred tax liability related to these basis differences existed at December 31, 2013 and 2012, respectively. The deferred tax liability related to the Prism Assets was reversed upon the sale of those assets as discussed further in Note 5. | ||||||||||||
Effective January 1, 2007, the Partnership became subject to the Texas margin tax, which is considered a state income tax, and is included in income tax expense on the Consolidated 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 $753, $1,575 and $713 were recorded in income tax expense for the years ended December 31, 2013, 2012 and 2011, respectively. | ||||||||||||
A current income tax liability of $1,204, and $10,239 existed at December 31, 2013 and 2012, respectively. | ||||||||||||

Stanolind Tank Damage | |
During the third quarter of 2011, a single tank fire occurred at the Partnership’s Stanolind Terminal in Beaumont, Texas. This specific tank stores No. 6 oil for Martin Resource Management under a throughput agreement. The tank contained approximately 3,200 barrels of No. 6 oil at the time the incident occurred, all of which was the property of Martin Resource Management. | |
Physical damage to the Partnership’s asset caused by the fire as well as the related removal and recovery costs, are fully covered by the Partnership’s non-windstorm insurance policy subject to a deductible of $443, which has been expensed and included in “operating expenses” in the Consolidated Statements of Operations for the year ended December 31, 2011. | |
Insurance proceeds received as a result of the this claim were used to replace the tank. The proceeds received exceeded the net book value of the tank that was destroyed and the Partnership recognized a gain in the amount of $909 in “other operating income” the Consolidated Statements of Operations for the year ended December 31, 2013. |

Principles of Presentation and Consolidation | |
The consolidated financial statements include the financial statements of the Partnership and its wholly-owned subsidiaries and equity method investees. 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 results of operations, financial position and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. In addition, the Partnership evaluates its relationships with other entities to identify whether they are variable interest entities under certain provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), 810-10 and to assess whether it is the primary beneficiary of such entities. If the determination is made that the Partnership is the primary beneficiary, then that entity is included in the consolidated financial statements in accordance with ASC 810-10. No such variable interest entities exist as of December 31, 2013 or 2012. | |
As discussed in Note 5, on July 31, 2012, the Partnership completed the sale of its East Texas and Northwest Louisiana natural gas gathering and processing assets. These assets, along with additional gathering and processing assets discussed in Note 5 are collectively referred to as the “Prism Assets.” The Partnership has presented the results of operations and cash flows of the Prism Assets as discontinued operations for the years ended December 31, 2012 and 2011. | |
On October 2, 2012, the Partnership, which owned 10.74% of the Class A interests and 100% of the Class B interests, acquired all of the remaining Class A interests in Redbird from Martin Underground Storage, Inc. (“MUS”), a subsidiary of Martin Resource Management. Redbird was formed by the Partnership and Martin Resource Management in 2011 to invest in Cardinal. | |
On October 2, 2012, the Partnership acquired from Cross Oil Refining and Marketing, Inc. (“Cross”), a wholly-owned subsidiary of Martin Resource Management, certain specialty lubricant product blending and packaging assets (“Blending and Packaging Assets”). | |
The acquisitions of the Redbird Class A interests and the Blending and Packaging Assets were considered a transfer of net assets between entities under common control. The acquisitions of the Redbird Class A interests and the Blending and Packaging Assets are recorded at amounts based on the historical carrying value of these assets at October 2, 2012, and the Partnership is required to update its historical financial statements to include the activities of the Redbird Class A interests and the Blending and Packaging Assets as of the date of common control. The Partnership’s accompanying historical financial statements have been retrospectively updated to reflect the effects on financial position, cash flows and results of operations attributable to the activities of the Redbird Class A interests and the Blending and Packaging Assets as if the Partnership owned these assets for the periods presented. Net income attributable to the Redbird Class A interests and the activities of the Blending and Packaging Assets for periods prior to the Partnership’s acquisition of the assets is not allocated to the general and limited partners for purposes of calculating net income per limited partner unit. See Note 16. | |
Certain expense reclassifications were made to the Partnership's Consolidated Statements of Operations for the years ended December 31, 2012 and 2011 in order to conform to the current presentation. | |
Product Exchanges | ' |
Product Exchanges | |
The Partnership enters into product exchange agreements with third parties, whereby the Partnership agrees to exchange natural gas liquids (“NGLs”) and sulfur with third parties. The Partnership records the balance of exchange products due to other companies under these agreements at quoted market product prices and the balance of exchange products due from other companies at the lower of cost or market. Cost is determined using the first-in, first-out (“FIFO”) method. Product exchanges with the same counterparty are entered into in contemplation of one another and are combined. The net amount related to location differentials is reported in “Product sales” or “Cost of products sold” in the Consolidated Statements of Operations. | |
Inventories | ' |
Inventories | |
Inventories are stated at the lower of cost or market. Cost is determined by using the FIFO method for all inventories except lubricants and lubricants packaging inventories. Lubricants and lubricants packaging inventories cost is determined using standard cost, which approximates actual cost, computed on a FIFO basis. | |
Revenue Recognition | ' |
Revenue Recognition | |
Terminalling and Storage – Revenue is recognized for storage contracts based on the contracted monthly tank fixed fee. For throughput contracts, revenue is recognized based on the volume moved through the Partnership’s terminals at the contracted rate. For the Partnership’s tolling agreement, revenue is recognized based on the contracted monthly reservation fee and throughput volumes moved through the facility. When lubricants and drilling fluids are sold by truck or rail, revenue is recognized upon delivering product to the customers as title to the product transfers when the customer physically receives the product. | |
Natural Gas Services – NGL distribution revenue is recognized when product is delivered by truck to the Partnership's NGL customers, which occurs when the customer physically receives the product. When product is sold in storage, or by pipeline, the Partnership recognizes NGL distribution revenue when the customer receives the product from either the storage facility or pipeline. | |
Sulfur Services – Revenue from sulfur product sales is recognized when the customer takes title to the product. Revenue from sulfur services is recognized as deliveries are made during each monthly period. | |
Marine Transportation – Revenue is recognized for time charters based on a per day rate. For contracted trips, revenue is recognized upon completion of the particular trip. | |
Equity Method Investments | ' |
Equity Method Investments | |
The Partnership uses the equity method of accounting for investments in unconsolidated entities where the ability to exercise significant influence over such entities exists. Investments in unconsolidated entities consist of capital contributions and advances plus the Partnership’s share of accumulated earnings as of the entities’ latest fiscal year-ends, less capital withdrawals and distributions. Investments in excess of the underlying net assets of equity method investees, specifically identifiable to property, plant and equipment, are amortized over the useful life of the related assets. Excess investment representing equity method goodwill is not amortized but is evaluated for impairment, annually. Under certain provisions of ASC 350-20, related to goodwill, this goodwill is not subject to amortization and is accounted for as a component of the investment. Equity method investments are subject to impairment under the provisions of ASC 323-10, which relates to the equity method of accounting for investments in common stock. No portion of the net income from these entities is included in the Partnership’s operating income. | |
Property, Plant and Equipment | ' |
Property, Plant, and Equipment | |
Owned property, plant, and equipment is stated at cost, less accumulated depreciation. Owned buildings and equipment are depreciated using straight-line method over the estimated lives of the respective assets. | |
Equipment under capital leases is stated at the present value of minimum lease payments less accumulated amortization. Equipment under capital leases is amortized on a straight line basis over the estimated useful life of the asset. | |
Routine maintenance and repairs are charged to operating expense while costs of betterments and renewals are capitalized. When an asset is retired or sold, its cost and related accumulated depreciation are removed from the accounts, and the difference between net book value of the asset and proceeds from disposition is recognized as gain or loss. | |
Goodwill and Other Intangible Assets | ' |
Goodwill and Other Intangible Assets | |
Goodwill is subject to a fair-value based impairment test on an annual basis, or more often if events or circumstances indicate there may be impairment. The Partnership is required to identify its reporting units and determine the carrying value of each reporting unit by assigning the assets and liabilities, including the existing goodwill and intangible assets. The Partnership is required to determine the fair value of each reporting unit and compare it to the carrying amount of the reporting unit. To the extent the carrying amount of a reporting unit exceeds the fair value of the reporting unit, the Partnership would be required to perform the second step of the impairment test, as this is an indication that the reporting unit goodwill may be impaired. | |
All four of the Partnership's “reporting units”, terminalling and storage, natural gas services, sulfur services and marine transportation, contain goodwill. | |
The Partnership has performed the annual impairment tests as of August 31, 2013, 2012, and 2011, and determined fair value in each reporting unit based on the weighted average of two valuation techniques: (i) the discounted cash flow method and (ii) the guideline public company method. At August 31, 2013, 2012, and 2011, the estimated fair value of each of the four reporting units was in excess of its carrying value, resulting in no impairment. | |
No triggering events occurred that would cause the Partnership to perform an impairment test at either December 31, 2013 or 2012. | |
Significant changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit which could give rise to future impairment. Changes to these estimates and assumptions can include, but may not be limited to, varying commodity prices, volume changes and operating costs due to market conditions and/or alternative providers of services. | |
Debt Issuance Costs | ' |
Debt Issuance Costs | |
Debt issuance costs relating to the Partnership’s revolving credit facility and senior unsecured notes are deferred and amortized over the terms of the debt arrangements. | |
Impairment of Long-Lived Assets | ' |
Impairment of Long-Lived Assets | |
In accordance with ASC 360-10, long-lived assets, such as property, plant and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the balance sheet. The Partnership has not identified any triggering events in 2013, 2012 or 2011 that would require an assessment for impairment of long-lived assets. | |
Asset Retirement Obligation | ' |
Asset Retirement Obligations | |
Under ASC 410-20, which relates to accounting requirements for costs associated with legal obligations to retire tangible, long-lived assets, the Partnership records an Asset Retirement Obligation (“ARO”) at fair value in the period in which it is incurred by increasing the carrying amount of the related long-lived asset. In each subsequent period, the liability is accreted over time towards the ultimate obligation amount and the capitalized costs are depreciated over the useful life of the related asset. The Partnership’s fixed assets include land, buildings, transportation equipment, storage equipment, marine vessels and operating equipment. | |
Derivative Instruments and Hedging Activities | ' |
Derivative Instruments and Hedging Activities | |
In accordance with certain provisions of ASC 815-10 related to accounting for derivative instruments and hedging activities, all derivatives and hedging instruments are included on the balance sheet as an asset or liability measured at fair value and changes in fair value are recognized currently in earnings unless specific hedge accounting criteria are met. If a derivative qualifies for hedge accounting, changes in the fair value can be offset against the change in the fair value of the hedged item through earnings or recognized in other comprehensive income until such time as the hedged item is recognized in earnings. | |
Derivative instruments not designated as hedges are marked to market with all market value adjustments being recorded in the Consolidated Statements of Operations. | |
Comprehensive Income | ' |
Comprehensive Income | |
Comprehensive income includes net income and other comprehensive income. Other comprehensive income for the Partnership includes unrealized gains and losses on derivative financial instruments. In accordance with ASC 815-10, the Partnership records deferred hedge gains and losses on its derivative financial instruments that qualify as cash flow hedges as other comprehensive income. | |
Use of Estimates | ' |
Use of Estimates | |
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 financial statements in conformity with accounting principles generally accepted in the U.S. Actual results could differ from those estimates. | |
Indirect Selling, General and Administrative Expense | ' |
Indirect Selling, General and Administrative Expenses | |
Indirect selling, general and administrative expenses are incurred by Martin Resource Management and allocated to the Partnership to cover costs of centralized corporate functions such as accounting, treasury, engineering, information technology, risk management and other corporate services. Such expenses are based on the percentage of time spent by Martin Resource Management’s personnel that provide such centralized services. Under an omnibus agreement with Martin Resource Management, the Partnership is required to reimburse Martin Resource Management for indirect general and administrative and corporate overhead expenses. | |
Environmental Liabilities and Litigation | ' |
Environmental Liabilities and Litigation | |
The Partnership’s policy is to accrue for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study. Such accruals are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable. | |
Accounts Receivable and Allowance for Doubtful Accounts | ' |
Accounts Receivable and Allowance for Doubtful Accounts. | |
Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Partnership’s best estimate of the amount of probable credit losses in the Partnership’s existing accounts receivable. | |
Deferred Catalyst Costs | ' |
Deferred Catalyst Costs | |
The cost of the periodic replacement of catalysts is deferred and amortized over the catalyst’s estimated useful life, which ranges from 24 to 36 months. | |
Deferred Turnaround Costs | ' |
Deferred Turnaround Costs | |
The Partnership capitalizes the cost of major turnarounds and amortizes these costs over the estimated period to the next turnaround, which ranges from 24 to 36 months. | |
Income Taxes | ' |
Income Taxes | |
With respect to the Partnership’s taxable subsidiary (Woodlawn Pipeline Co., Inc.) and the Blending and Packaging Assets prior to the date of acquisition from Cross, income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. |

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 2.00% to 3.00% and the applicable margin for revolving loans that are base prime rate loans ranges from 1.00% to 2.00%. The applicable margin for LIBOR borrowings at December 31, 2013 is 3.00%. 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 Omnibus Agreement. The Partnership is permitted to make quarterly distributions so long as no event of default exists. | ||||||||
2 Pursuant to the indenture under which the senior notes were issued, the Partnership has the option to redeem up to 35% of the aggregate principal amount at a redemption price of 108.875% of the principal amount, plus accrued and unpaid interest with the proceeds of certain equity offerings. On April 24, 2012, the Partnership notified the trustee of its intention to exercise a partial redemption of the Partnership’s senior notes pursuant to the indenture. On May 24, 2012, the Partnership redeemed $25,000 of the senior notes from various holders using proceeds of the Partnership’s January 2012 follow-on equity offering, which in the interim were used to pay down amounts outstanding under the Partnership’s revolving credit facility. In conjunction with the redemption, the Partnership incurred a debt prepayment premium in the amount of $2,219, which is included in the Consolidated Statement of Operations for the year ended December 31, 2012. | ||||||||
3 Effective March 28, 2013, the Partnership increased the maximum amount of borrowings and letters of credit available under the Credit Facility from $400,000 to $600,000 and extended the maturity date of the facility from April 2016 to March 2018. | ||||||||
4 On February 11, 2013, the Partnership completed a private placement of $250,000 in aggregate principal amount of 7.250% senior unsecured notes due 2021 to qualified institutional buyers under Rule 144A. The Partnership filed with the SEC a registration statement to exchange the 2021 Notes for substantially identical notes that are registered under the Securities Act, and completed the exchange offer on July 31, 2013. | ||||||||
5 The 2018 and 2021 indentures restrict the Partnership’s ability to sell assets; pay distributions or repurchase units or redeem or repurchase subordinated debt; make investments; incur or guarantee additional indebtedness or issue preferred units; and consolidate, merge or transfer all or substantially all of its assets. Many of these covenants will terminate if the notes achieve an investment grade rating from each of Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services and no default (as defined in the indentures) has occurred. | ||||||||
6 In November of 2013, the Partnership retired the capital lease obligations with borrowings under the Partnership's revolving credit facility. In conjunction with the retirement, the Partnership incurred a debt prepayment premium in the amount of $272, which is included in the Consolidated Statement of Operations for the year ended December 31, 2013. | ||||||||

[1] | On February 11, 2013, the Partnership completed a private placement of $250,000 in aggregate principal amount of 7.250% senior unsecured notes due 2021 to qualified institutional buyers under Rule 144A. The Partnership filed with the SEC a registration statement to exchange the 2021 Notes for substantially identical notes that are registered under the Securities Act, and completed the exchange offer on July 31, 2013. | |||||||||||||||||||||||||||||||
[2] | The 2018 and 2021 indentures restrict the Partnership’s ability to sell assets; pay distributions or repurchase units or redeem or repurchase subordinated debt; make investments; incur or guarantee additional indebtedness or issue preferred units; and consolidate, merge or transfer all or substantially all of its assets. Many of these covenants will terminate if the notes achieve an investment grade rating from each of Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services and no default (as defined in the indentures) has occurred. | |||||||||||||||||||||||||||||||
[3] | In October of 2013, the Partnership retired the note payable to bank with borrowings under the Partnership's revolving credit facility. | |||||||||||||||||||||||||||||||
[4] | In November of 2013, the Partnership retired the capital lease obligations with borrowings under the Partnership's revolving credit facility. In conjunction with the retirement, the Partnership incurred a debt prepayment premium in the amount of $272, which is included in the Consolidated Statement of Operations for the year ended December 31, 2013. | |||||||||||||||||||||||||||||||
[5] | Effective March 28, 2013, the Partnership increased the maximum amount of borrowings and letters of credit available under the Credit Facility from $400,000 to $600,000 and extended the maturity date of the facility from April 2016 to March 2018. | |||||||||||||||||||||||||||||||
[6] | Pursuant to the indenture under which the senior notes were issued, the Partnership has the option to redeem up to 35% of the aggregate principal amount at a redemption price of 108.875% of the principal amount, plus accrued and unpaid interest with the proceeds of certain equity offerings. On April 24, 2012, the Partnership notified the trustee of its intention to exercise a partial redemption of the Partnership’s senior notes pursuant to the indenture. On May 24, 2012, the Partnership redeemed $25,000 of the senior notes from various holders using proceeds of the Partnership’s January 2012 follow-on equity offering, which in the interim were used to pay down amounts outstanding under the Partnership’s revolving credit facility. In conjunction with the redemption, the Partnership incurred a debt prepayment premium in the amount of $2,219, which is included in the Consolidated Statement of Operations for the year ended December 31, 2012. | |||||||||||||||||||||||||||||||
[7] | 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 2.00% to 3.00% and the applicable margin for revolving loans that are base prime rate loans ranges from 1.00% to 2.00%. The applicable margin for LIBOR borrowings at December 31, 2013 is 3.00%. 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 Omnibus Agreement. The Partnership is permitted to make quarterly distributions so long as no event of default exists. |
