S&R Compression, LLC

Report on the Financial Statements

We have audited the accompanying financial statements of S&R Compression, LLC which comprise the balance sheets as of December 31, 2012 and 2011, and the related statements of income, members’ equity and cash flows for the years then ended and the related notes to the financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these 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 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 these 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 financial statements are free of material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements.  The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error.  In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the 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 entity’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 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 financial statements referred to above present fairly, in all material respects, the financial position of S&R Compression, LLC as of December 31, 2012 and 2011, and the results of its operations and its cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

NOTES TO FINANCIAL STATEMENTS

December 31, 2012 and 2011

Note 1 — Business and Basis of Presentation

Business

S&R Compression, LLC (the Company), primarily owned by Argonaut Private Equity, L.L.C. (APE), was formed on June 4, 2007, to manage S&R Equipment, Inc. (SRE), a company owned by APE, and to hold and rent newly constructed compressors used primarily in crude oil production related gas lift operations in Oklahoma and Texas.  Since that date, only a small portion of compressor fabrication was for direct sale to third parties.  The Company has a rental fleet of 928 units as of December 31, 2012, of which 857 are in service.  Several companies, which are affiliated with APE through common ownership, provide services to the Company and these relationships, when applicable, are described within the following notes.

Basis of presentation

The accompanying financial statements include only the accounts, results of operations and cash flows of the Company.  No affiliates were combined in this financial statement presentation.

Note 2 — Significant Accounting Policies

Cash and treasury management

Kaiser-Francis Management Company L.L.C. (KFMC) manages the cash and treasury functions on behalf of the Company.  Daily sweeps are made from the Company’s bank account to a KFMC bank account with such amounts offsetting the affiliate receivable or payable.

Accounts receivable

Accounts receivable are stated at the amount management expects to collect.  Management provides for probable uncollectible amounts through a charge to earnings based on its assessment of the current status of individual accounts.  Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the allowance for doubtful accounts.  Management determined that no allowance for bad debts was necessary at December 31, 2012 or 2011.

Affiliate accounts receivable and advances payable

Affiliate accounts receivable are amounts due from SRE for management fees and operating expenditures incurred by the Company on behalf of SRE.  Affiliate advances payable represent the amounts due to KFMC for the most recent month’s operational activity and any accrued payables to KFMC.  Before debt financing in 2012, costs incurred by KFMC on behalf of the Company was generally reimbursed the following month, after capital contributions were made into the Company.

Property, plant and equipment

Property, plant and equipment are carried at cost and depreciated over the respective useful lives of the assets, with an estimated 10% salvage value, using the straight line method.  Land is not depreciated.

6

Building and plant assets are depreciated over the assets’ remaining lives, 10 to 25 years.  Autos and trucks are depreciated over five years.

Rental equipment

Rental equipment is depreciated using the straight line method based on a 20-year useful life for new or recently constructed compressors and a 15-year life for acquired compressors more than five years old.  Depreciation on rental equipment begins when the asset is first placed into service.  Overhauls and major improvements that increase the value or extend the life of the compressor unit are capitalized and depreciated over the remaining life of the compressor.  At December 31, 2012 and 2011, rental equipment with remaining cost of $97,846,438 and $68,982,929, respectively, was being depreciated and rental equipment with a cost of $7,833,794 and $6,351,531, respectively, had not been placed into service and therefore was not being depreciated.

Impairment of property, plant and rental equipment

The Company regularly evaluates long-lived assets including property, plant and equipment and rental equipment for potential impairment whenever events or circumstances indicate the carrying value of the assets may not be recoverable from the estimated future cash flows expected to result from their use and eventual disposition.  If the undiscounted expected future cash flows are less than the carrying value, an impairment loss is recognized equal to an amount by which the carrying value exceeds the fair value of the assets. Fair value is generally determined from estimated discounted future net cash flows.

Revenue recognition

Fabrication revenue is recorded when billed, based on individual contract terms.  The Company provides custom electric and engine driven compressor packages primarily for customers in the oil and gas industry for lease under certain terms agreed to by the customer.  Fleet rental revenue and fees are recognized over the rental term.  Cash received prior to the period in which it should be recognized is deferred and recognized according to the rental term. Revenue is accrued for uncollected amounts due and an allowance is calculated based on historical collection experience. Initial lease terms are typically six months or longer and extensions of such leases are typically on a month-to-month basis.  All of the Company’s customer agreements are considered operating leases under the provisions of ASC 840, Leases.  Initial direct costs related to the Company’s customer agreements are expensed as incurred and have been classified as operating expenses in the Company’s accompanying statements of income.

Shipping and handling costs

Costs incurred to ship compressors sold and fleet rentals to customer locations of $496,637 and $441,847 for the years ended December 31, 2012 and 2011, respectively, are included in operating expenses in the accompanying statements of income.

Concentrations of credit risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of accounts receivable.  Generally, the Company does not require collateral for accounts receivable arising from the normal course of business.  At December 31, 2012, four customers accounted for 50% of total accounts receivable. At December 31, 2011, five customers accounted for 57% of total accounts receivable.  For the year ended December 31, 2012, two customers accounted for 34% of rental income and for the year ended December 31, 2011, four customers accounted for 48% of rental income.

Income taxes

The Company has elected to be taxed as a pass-through entity.  Therefore, income taxes on the Company’s net earnings are allocated to the members in accordance with their respective percentage ownership and no income tax provision or liability is reflected in the Company’s financial statements.

The accounting for income taxes may, at times, involve some degree of uncertainty and, as such, lead to uncertain tax positions having been taken.  Management evaluated the Company’s tax positions and concluded that it has taken no uncertain tax positions that require adjustments to the financial statements.  Generally, the Company is no longer subject to income tax examinations by the U.S., federal, state, or local tax authorities for years before 2009.

Use of estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

New accounting pronouncements

The Financial Accounting Standards Board (FASB) periodically issues new accounting standards in a continuing effort to improve standards of financial accounting and reporting. Management has reviewed recently issued pronouncements and concluded that there are no recently issued accounting pronouncements that the Company has yet to adopt that are expected to have a material effect on the Company’s financial position, results of operations or cash flows.

Subsequent events

Management has evaluated subsequent events through August 27, 2013, the date the financial statements were available to be issued.

Note 9 — Fair Value of Financial Instruments

Based on their relative short terms, variable interest rates and other relevant factors, the Company has determined that the carrying value of the affiliate notes receivable and debt approximate their fair values.  However, considerable judgment is required in interpreting these factors.  Accordingly, the use of different assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.
