Independent Auditor’s Report





To the Members of Cardinal Gas Storage Partners LLC





We have audited the accompanying consolidated financial statements of Cardinal Gas Storage Partners LLC and its subsidiaries, which comprise the consolidated  statements of financial position  as of December 31, 2013 and 2012, and the related consolidated statements of operations, of members’ capital and of cash flows for each of the three years in the period ended December 31, 2013.





Management's Responsibility for the Consolidated  Financial Statements


Management is responsible for the preparation and fair presentation of the consolidated  financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated  financial statements that are free from material misstatement, whether due to fraud or error.





Auditor's Responsibility


Our responsibility is to express an opinion on the consolidated financial statements based on our audits.  We conducted our audits in accordance with auditing standards generally accepted in the United States of America.  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free from material misstatement.





An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements.  The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the consolidated  financial statements, whether due to fraud or error.  In making those risk assessments, we consider internal control relevant to the Company's preparation and fair presentation of the consolidated financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control.  Accordingly, we express no such opinion.  An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements.  We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.





Opinion


In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Cardinal Gas Storage Partners LLC and its subsidiaries at December 31, 2013 and 2012, and the results of their operations, their comprehensive income, and their cash flows for each of the three years in the period ended December 31, 2013 in accordance with accounting principles generally accepted in the United States of America.

1. Business Description, Formation of Company and Acquisitions





Cardinal Gas Storage Partners LLC (the “Company”) was formed on May 1, 2008, as a Delaware limited liability company with Energy Capital Partners (ECP) and Martin Resource Management Corporation (“MRMC”) as the two members.  In April 2011, Redbird Gas Storage LLC (“Redbird”) was formed as a joint venture between MRMC and Martin Midstream Partners (“MMLP”).  In October 2012, MMLP acquired the MRMC interest in Redbird.  As a result of this transaction, Redbird is now a wholly owned subsidiary of MMLP.  As of December 31, 2013, ECP had a 58.2% ownership and Redbird had a 41.8% ownership in the Company.





The Company focuses on the development, construction, operation, and management of natural gas storage facilities.


The Company has four natural gas storage facilities in operation.  Arcadia Gas Storage LLC (“Arcadia”), located in Bienville Parish, Louisiana is in service with approximately 14.5 bcf of working gas storage capacity.  Monroe Gas Storage LLC (“Monroe”), located in Monroe County, Mississippi, is in operation with a current working gas capacity of approximately 7.0 bcf.  Cadeville Gas Storage LLC (“Cadeville”), located in Ouachita Parish, Louisiana was placed into operation during 2013 with working gas capacity of 20.0 bcf. Perryville Gas Storage LLC (“Perryville”), located in Franklin Parish, Louisiana was placed into operation during 2013 with working gas capacity of 8.7 bcf.  These facilities provide producers, end users, local distribution companies, pipelines and energy marketers with high deliverability storage services and hub services.


The Company maintains two classes of member units, Category A units and Category B units.  Category B Unit holders do not receive loss allocations; however, they do participate in income resulting from certain triggering events, including the sale of assets or the sale of the Company.  The Board approved 7% to be allocated as Category B units; however, due to departed employees during 2012 and 2013, only 6.46% is currently outstanding as of December 31, 2013.  Income is allocated first to Category A members until certain conditions are met; thereafter, 93.54% and 6.46% to Category A and Category B members, respectively.


Under the LLC agreement, each Category A member appoints two managers to the Board.  If either member fails to hold a 30%-interest in the Company, one manager position would be transferred to the other member.


The wholly owned subsidiaries of the Company are Arcadia Gas Storage Holding LLC, Cadeville Gas Storage Holding LLC, Perryville Gas Storage Holding LLC, MGS Holding LLC, and Cardinal Gas Consulting LLC.


2.       Summary of Significant Accounting Policies


Basis of Presentation


The consolidated financial statements and the accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (GAAP).  The consolidated financial statements include the accounts of the Company and the subsidiaries on a consolidated basis.  All intercompany transactions have been eliminated.


Management’s Estimates and Assumptions


The preparation of consolidated financial statements in conformity with the accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements.  Actual results could differ from these estimates.


Subsequent Events


The Company has performed an evaluation of subsequent events through March 28, 2014, which is the date the financial statements were made available for issuance.


Cash and Cash Equivalents


The Company considers cash and highly liquid investments with a maturity of three months or less, at the time of purchase, to be cash equivalents.

Restricted Cash


At December 31, 2013 and 2012, the Company held $14.9 and $12.8 million in restricted cash, respectively.  As of December 31, 2013 and 2012, respectively, $11.5 million and $3.6 million of this balance was restricted under the terms of a loan agreement for the primary purpose of making future principal reduction payments, $2.7 million and $6.4 million was restricted for the purpose of funding development costs, and $0.7 million and $2.8 million was restricted for distributions to members under the terms of the partnership agreement.  The 2013 and 2012 distributions were made to Redbird on January 31, 2014 and January 25, 2013, respectively.  The ECP distribution was held to offset future contributions and is reflected within accrued liabilities as of December 31, 2013 and 2012.


Accounts Receivable and Bad Debt


Trade accounts receivable are recorded at the invoiced amount and do not bear interest.  The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing accounts receivable.  As of December 31, 2012, management considered $0.02 million to be uncollectible and, accordingly, established an allowance for doubtful accounts.  As of December 31, 2013, all receivables were considered collectible and no allowance for doubtful accounts was recorded.


Inventory


Inventory consists of natural gas received as a result of fuel revenue and certain balancing agreements and is stated at the lower of weighted average cost or market.  The inventory balance as of December 31, 2013 and 2012 is reflected within other current assets on the statement of financial position.


Revenue Recognition


The Company provides various types of natural gas storage services to customers.  Revenues from these services are classified as firm capacity revenue, hub services revenue, and fuel charges.  In addition, the Company provided consulting services for natural gas storage projects.  Revenues from these consulting services are classified as professional service fees.


Firm capacity revenues consist of (i) firm storage reservation revenues - contractually obligated monthly capacity reservation fee.  These fees are paid to the Company and recognized in revenue over the term of the contract regardless of the actual storage capacity utilized. (ii) Firm storage cycling revenues for the use of injection and withdrawal services based on the volume of natural gas nominated for injection and/or withdrawal.  These fees are recognized in revenue in the period the volumes are nominated.


Hub service revenue consist of fees from (i) “interruptible” storage services pursuant to which customers receive only limited assurance regarding the availability of capacity in the Company’s storage facilities and pay fees based on actual utilization of assets, (ii) “park and loan” services and (iii) “wheeling and balancing” services pursuant to which customers pay fees for the right to move a volume of gas through our facilities from an interconnection point to another and true up their deliveries of gas to, or takeaways of gas from, our facilities.  A portion of our revenues related to these activities may include fuel collections.


Fuel charges consist of the small portion of a customer’s natural gas nominated for injection retained by the Company as compensation for fuel use.  These fees are reflected as revenue when received.  Any excess fuel collected is carried as inventory until sold.


Professional service fees consist of consulting services and are recognized as the services are performed.


Property and Equipment


Property and equipment are recorded at cost.  The costs of major renewals and betterments are capitalized; repair and maintenance costs are expensed as incurred.  The Company capitalizes interest related to the debt facility used for funding development as well as certain general and administrative costs associated with employees that are deemed to be dedicated to capitalized projects in process.  When assets are sold or retired, the cost and related accumulated depreciation are removed from the appropriate accounts, and the resulting gain or loss is included in current operations.  Leasehold improvements are capitalized and amortized over the lesser of their estimated useful lives or the applicable lease term.

Depreciation of property and equipment is provided over the estimated useful lives of the property as follows: Straight LineStorage, surface and pipeline facilities20 to 50-yearOffice equipment5 to 7-yearAutomobiles5-year


Impairment of Long-lived Assets


The Company ensures its 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.  If an evaluation were required, the estimated future undiscounted cash flows associated with the asset would be compared to the asset’s carrying amount to determine whether a write-down is required.  If this review indicates that the assets will not be recoverable, the carrying value of the Company’s assets would be reduced to their estimated market value.


During the winter of 2013 and early 2014, the Company determined that the Monroe facility was not able to perform at the previously calculated 9 bcf of working gas capacity.  The facility was determined to have working gas capacity of 7 bcf at two turns.  Based on the asset’s capability, an impairment of the Monroe fixed assets was calculated using a discounted cash flow model and recorded in the amount of $129.4 million in 2013 on the consolidated statements of operations.


In September 2012, the Company determined that a natural gas storage project in Colorado was no longer a favorable investment.  The Company had previously purchased gas storage rights and mineral rights with the intention of constructing a storage facility but was unable to obtain agreements for all of the rights needed to pursue the project.  The project assets were written off resulting in a loss from abandoned projects of $1.3 million in 2012 on the consolidated statements of operations.


In 2012, macro-economic factors including low gas prices and low gas price volatility reduced the amount of active gas storage development projects and the trend had a significant impact on the valuation metrics used in determining the long-term estimated value of the Company’s wholly owned subsidiary Cardinal Gas Consulting LLC (“IGC”).  These specific negative factors, combined with (i) lower enterprise values resulting from lower multiples of revenues and EBITDA comparables, and (ii) the lack of relevant third party transactions due to depressed macro-economic conditions, resulted in goodwill impairment of approximately $0.6 million in 2012.


Debt Issuance Costs


Costs incurred for debt borrowings are capitalized and amortized over the life of the associated debt utilizing the effective interest rate method.  When debt is retired before its scheduled maturity date, any remaining transaction-related costs associated with that debt are expensed.  Total amortization for the years ended December 31, 2013, 2012 and 2011 was approximately $1.9 million, $1.6 million and $1.1 million, of which approximately $0.6 million, $1.1 million and $0.6 million was capitalized during the period of construction, respectively.


Income Taxes


The Company’s taxable income (loss) is reported on the respective income tax returns of its members.  With respect to a franchise or income tax imposed by a state or local municipality, these taxes are accounted for under the asset and liability method.


The amount of Texas margin tax for the years ended December 31, 2013, 2012 and 2011 was approximately $4.8, $3.5 and $1.0, respectively.  No Louisiana franchise tax was due for any of these years.


Derivative Instruments and Hedging Activities


The Company records its derivative instruments 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.

Cardinal Gas Storage Partners, LLC and Subsidiaries

 (Dollars in thousands, except where otherwise indicated)


Derivative instruments not designated as hedges are marked-to-market with all market value adjustments recorded in the consolidated statement of operations.  As of December 31, 2013, the Company has not elected hedge accounting for any of its derivative instruments.  Fair value changes for these derivative instruments have been recorded in the consolidated statement of operations.


Fair Value of Financial Instruments


The Company’s financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables, long-term debt and derivative instruments.  Management considers the carrying values of cash and cash equivalents, trade receivables and trade payables to be representative of their respective fair values because of their short-term maturities or expected settlement dates.  The carrying value of outstanding amounts under the revolving credit facility and term debt approximate fair value due to the floating interest rate.  Derivative instruments are recorded at fair value in the accompanying statements of financial position.


The authoritative guidance related to fair value defines a hierarchy of inputs to valuation techniques based upon whether those inputs reflect assumptions other market participants would use based upon market data obtained from independent sources (observable inputs).  The following summarizes the fair value hierarchy:


Level 1    Inputs utilize quoted prices in active markets for identical assets or liabilities.


|        |                                                                                                                                                     
|------- | ----------------------------------------------------------------------------------------------------------------------------------------------------
|Level 2 | Inputs utilize data points other than quoted prices included in Level 1, that are observable such as quoted prices, interest rates and yield curves.

|        |                                                                                                                                                                   
|------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------
|Level 3 | Inputs are unobservable data points for the asset or liability, and includes situations where there is little, if any, market activity for the asset or liability.

The Company performed an analysis on its derivative instruments and recorded a net asset related to its derivative instruments of approximately $1.6 million for both the years ended December 31, 2013 and 2012, within Level 2 of the fair value hierarchy.  Refer to Note 9 for more information on these instruments.


The Company does not have any other assets or liabilities classified within Level 3 of the fair value hierarchy.  The carrying amounts reflected in the statements of financial position for other current assets and accrued expenses approximate fair value due to their short-term maturities.


Asset Retirement Obligations and Environmental Liabilities


FASB guidance establishes accounting requirements for retirement obligations associated with tangible long-lived assets including (i) the timing of the liability recognition, (ii) initial measurement of the liability, (iii) allocation of asset retirement cost to expense, (iv) subsequent measurement of the liability and (v) financial statement disclosures.  FASB guidance also requires that the cost for asset retirement should be capitalized as part of the cost of the related long-lived asset and subsequently allocated to expense using a systematic and rational method.  The Company assets have contractual or regulatory obligations to perform remediation when the assets are abandoned.  These assets, with regular maintenance, will continue to be in service for many years to come.  It is not possible to predict when demands for our services will cease and we do not believe that such demand will cease for the foreseeable future.  Accordingly, the Company believes the date when these assets will be abandoned is indeterminate.  With no reasonably determinable abandonment date, the Company cannot reasonably estimate the fair value of the associated asset retirement obligation.  The Company will record an asset retirement obligation in the period in which sufficient information becomes available for us to reasonably determine the settlement date.


The Company’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.


The Company has not identified any environmental remediation obligations as of December 31, 2013.

Pad Gas Lease


The Company has a lease agreement with Credit Suisse executed on June 12, 2009 for the lease of 3.6 bcf of natural gas to use as pad gas for the storage facility at Monroe.  The lease agreement expires on January 1, 2015.  The Company is required to begin returning the natural gas to Credit Suisse upon expiration of the lease and to have all 3.6 bcf of the leased gas returned by the end of February 2015.


During 2011, approximately 2.5 bcf of pad gas was determined to be unrecoverable from the Monroe reservoir.  The Company executed an agreement with Credit Suisse on April 20, 2012 requiring that on or before May 1, 2012, this approximate amount will be placed into an escrow fund for the repurchase of leased base gas.  All base gas was repurchased as of January 2013 and the funds were released from escrow.  This agreement waived default, and the pad gas lease is in good standing.  A liability in the amount of $5.7 million was accrued as a short term liability on the consolidated statements of financial position as of December 31, 2011, of which 0.05 bcf, valued at $0.2 million, remained as of December 31, 2012.  No liability remained as of December 31, 2013.


Share-Based Payments


The Company recognizes compensation expense for all stock-based compensation based on the fair value of the awards granted, net of estimated forfeitures, at the date of grant.  The Company maintained one class of membership interests that were granted to employees of the Company.  Category B membership interests, totaling 7.0% of the total membership interests, were granted to employees in various dates in 2008, 2009, and 2010.  However, due to departed employees during 2012 and 2013, only 6.46% is held by Category B Unit holders as of December 31, 2013. Category B membership interests vest over an average service period of four years.  Prior to Category B membership interests receiving profit allocations or equity distributions, certain future triggering events must occur.  No compensation expense has been recorded as the category B membership interests have an initial threshold value of $0.


Capitalization of Interest


Interest on borrowed funds is capitalized on projects during construction based on the approximate average interest rate of the Company’s debt.  The Company capitalized $2.7 million, $3.5 million and $3.1 million during the years ended December 31, 2013, 2012 and 2011, respectively.


3.       Acquisition





On May 31, 2011, the Company acquired 100% of the equity interests of Monroe for an aggregate purchase price of $147.8 million in cash.


The fair value of assets acquired and liabilities assumed is as follows: Current assets$5,075Fixed assets135,135Intangible assets12,968Goodwill316Total assets acquired153,494Total liabilities assumed(5,677)Net assets acquired$147,817


In April 2012, the Company received $5.5 million, less a $0.5 million working capital adjustment, from the Acquisition Indemnification Holdback Escrow account as a result of an indemnity claim for approximately 2.5 bcf of lease pad gas that was not recoverable from the reservoir.  This net receipt of $5.0 million is reflected as a receivable on the consolidated statements of financial position as of December 31, 2011.

On April 1, 2013, Arcadia sold 1.22 bcf of base gas for $4.9 million, reducing the total base gas from 2.22 bcf to 1.0 bcf.  This sale was made in order to reduce the amount of capital invested in base gas through entering into a low-turn storage agreement with Cadeville.  This low-turn contract allows Arcadia to maintain the required cavern pressure by injecting water into the cavern as needed rather than holding base gas.  The historical cost of the non-depreciable base gas asset was $5.8 million, resulting in a loss on the sale of assets of $0.9 million.

7.       Concentrations





Concentration of Credit Risk


As of December 31, 2013, the Company had cash deposits with financial institutions in excess of the amount insured by the Federal Deposit Insurance Corporation.  Management believes that any credit risk associated with excess deposits in these financial institutions is minimal.


The Company’s principal customers for natural gas storage are natural gas pipeline and natural gas marketing companies.  These concentrations of customers may affect the Company’s overall credit risk in that certain customers may be similarly affected by changes in economic, regulatory, or other factors.  Where exposed to credit risk, the Company analyzes the counterparties’ financial condition prior to entering into an agreement, obtains additional financial assurance where possible through guarantees and letters of credit, establishes credit limits, and monitors the appropriateness of those limits on an ongoing basis.


Gas Storage Inventory


At December 31, 2013 and 2012, the value of gas storage inventory held for others was approximately $192.9 million and $45.1 million, respectively.  There were no gas loan transactions.  This balance represents the volume of stored natural gas valued at December 31, 2013 and 2012, respectively, utilizing the closing prices of various published delivery points.  Because the Company does not take title to the gas, the Company’s gas storage inventory and loan transactions are not recorded in the consolidated statement of financial position.


Significant Customers


Significant customers are those that individually account for more than 10% of the Company’s consolidated revenues or accounts receivables.  For the year ended December 31, 2013, four customers accounted for approximately 26%, 16%, 14% and 12% of the Company’s total revenues.  At December 31, 2013, four customers accounted for approximately 41%, 14%, 11% and 11% of the Company’s accounts receivable.  For the year ended December 31, 2012, four customers
