(1) Organization and Summary of Significant Accounting Policies

(a) Organization

USA Compression Partners, LP (the “Partnership”) is a publicly traded Delaware limited partnership formed to own and operate the business conducted by its subsidiaries. The common units representing limited partner interests in the Partnership (“common units”) are listed on the New York Stock Exchange (“NYSE”) under the symbol “USAC.” USA Compression GP, LLC, the general partner of the Partnership (the “General Partner”), is owned by USA Compression Holdings, LLC (“USA Compression Holdings”). Unless the context requires otherwise, references to “we,” “us,” “our,” or “the Partnership” are intended to mean the business and operations of the Partnership and its wholly owned, consolidated subsidiaries (the “Operating Subsidiaries”). References to “Argonaut” and related parties refer to Argonaut Private Equity, L.L.C. and certain related parties.

The Partnership, through its Operating Subsidiaries, primarily provides natural gas compression services under term contracts with customers in the crude oil and natural gas industry, using natural gas compression packages that it designs, engineers, owns, operates and maintains. The unaudited condensed consolidated financial statements include the accounts of the Partnership and the Operating Subsidiaries, and all intercompany balances and transactions have been eliminated in consolidation.

The Partnership’s ownership is as follows:


	June 30, 2015
	USA
	Compression		Argonaut and
	Holdings		Related Parties		Public		Total
General partner interest	1.6	%	—		—		1.6	%
Limited partner interest:
Common unitholders	12.6	%	16.6	%	39.6	%	68.8	%
Subordinated unitholders	29.6	%	—		—		29.6	%
Total	43.8	%	16.6	%	39.6	%	100.0	%

Partnership net income (loss) is allocated to the partners, both general and limited, in proportion to their respective interest in the Partnership.

(b) Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Partnership have been prepared on the same basis as the audited consolidated financial statements included in the Partnership’s annual report on Form 10-K for the year ended December 31, 2014 (the “2014 Annual Report”). In the opinion of the Partnership’s management, such financial information reflects all adjustments necessary for a fair presentation of the financial position as of June 30, 2015 and December 31, 2014, and the results of operations for the three months and six months ended June 30, 2015 and 2014, changes in partners’ capital for the six months ended June 30, 2015 and the statements of cash flows for the six months ended June 30, 2015 and 2014 in accordance with U.S. generally accepted accounting principles (“GAAP”). Operating results for the three months and six months ended June 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Therefore, these consolidated financial statements should be read in conjunction with the Partnership’s audited consolidated financial statements for the year ended December 31, 2014 contained in our 2014 Annual Report filed on February 19, 2015.

The unaudited condensed consolidated financial statements of the Partnership have been prepared in conformity with GAAP, which includes the use of estimates and assumptions by management that affect the reported amounts of assets, liabilities, revenues, expenses and disclosure of contingent assets and liabilities that exist at the date of the unaudited condensed consolidated financial statements. Although these estimates are based on management’s available knowledge of current and expected future events, actual results could differ from these estimates.

(d) Identifiable Intangible Assets

As of June 30, 2015, identifiable intangible assets, net consisted of the following (in thousands):


	Customer				Non-compete
	Relationships		Trade Names		Agreement		Total
Net Balance at December 31, 2014	$	68,653	$	13,104	$	600	$	82,357
Amortization Expense		(1,368)		(312)		(112)		(1,792)
Net Balance at June 30, 2015	$	67,285	$	12,792	$	488	$	80,565

Identifiable intangible assets are amortized using the straight-line method over their estimated useful lives, which is the period over which the assets are expected to contribute directly or indirectly to the Partnership’s future cash flows. The estimated useful lives range from 4 to 30 years. Accumulated amortization of intangible assets was $14.6 million and $12.8 million as of June 30, 2015 and December 31, 2014, respectively.

The Partnership assesses identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Partnership did not record any impairment of identifiable intangible assets for the three and six months ended June 30, 2015 or the three and six months ended June 30, 2014.

(e) Property and Equipment

Property and equipment are carried at cost. Overhauls and major improvements that increase the value or extend the life of compressor equipment are capitalized and depreciated over 3 to 5 years. Ordinary maintenance and repairs are charged to cost of operations, exclusive of depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets as follows:


Compression equipment		20 - 25 years
Furniture and fixtures		7 years
Vehicles and computer equipment		3 - 7 years
Leasehold improvements		5 years

See more information on property and equipment in Note 3 to our unaudited condensed consolidated financial statements.

(f) Impairments of Long-Lived Assets

Long-lived assets with recorded values that are not expected to be recovered through future cash flows are written-down to estimated fair value. An asset shall be tested for impairment when events or circumstances indicate that its carrying value may not be recoverable or will no longer be utilized in the operating fleet. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value exceeds the sum of the undiscounted cash flows associated with the operating fleet, an impairment loss equal to the amount of the carrying value exceeding the fair value of the asset is recognized. The fair value of the asset is measured using quoted market prices or, in the absence of quoted market prices, is based on an estimate of discounted cash flows, the expected net sale proceeds compared to the other similarly configured fleet units the Partnership recently sold or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment the Partnership plans to use.

Refer to Note 3 for more detailed information about impairment charges during the three and six months ended June 30, 2015.

(g) Fair Value Measurements

Accounting standards on fair value measurements establish a framework for measuring fair value and stipulate disclosures about fair value measurements. The standards apply to recurring and nonrecurring financial and non-financial assets and liabilities that require or permit fair value measurements. Among the required disclosures is the fair value hierarchy of inputs the Partnership uses to value an asset or a liability. The three levels of the fair value hierarchy are described as follows:

Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Partnership has the ability to access at the measurement date.

Level 2 inputs are those other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

Level 3 inputs are unobservable inputs for the asset or liability.

As of June 30, 2015 and December 31, 2014, the Partnership’s financial instruments consisted primarily of cash and cash equivalents, trade accounts receivable, trade accounts payable and long-term debt. The book values of cash and cash equivalents, trade accounts receivable and trade accounts payable are representative of fair value due to their short-term maturity. The carrying amount of long-term debt approximates fair value due to the floating interest rates associated with the debt.

Phantom unit awards granted to employees under the USA Compression Partners, LP 2013 Long-Term Incentive Plan (the “LTIP”) are accounted for as a liability, and such liability is re-measured on a quarterly basis. The liability is based on the publicly quoted price of the Partnership’s common units, which is considered a Level 1 input. As of June 30, 2015 and December 31, 2014, unit-based compensation liability was $1.2 million and $1.3 million, respectively.

(h) Operating Segment

The Partnership operates in a single business segment, the compression services business.

We recognized $20.6 million and $16.1 million of depreciation expense on property and equipment for the three months ended June 30, 2015 and 2014, respectively. We recognized $40.4 million and $31.5 million of depreciation expense on property and equipment for the six months ended June 30, 2015 and 2014, respectively.

As of June 30, 2015 and December 31, 2014, there was $18.6 million and $32.4 million, respectively, of property and equipment purchases in accounts payable and accrued liabilities.

During the six months ended June 30, 2015, non-cash transfers of inventory to and from property and equipment totaled approximately $0.7 million. These transfers have been treated as non-cash inventory activities in the Unaudited Condensed Consolidated Statements of Cash Flows.

During the six months ended June 30, 2015, insurance recoveries of $0.2 million were received on previously impaired compression equipment and are reported within the Loss (gain) on sale of assets line in the Unaudited Condensed Consolidated Statement of Operations.

During the quarter ended June 30, 2015, the Partnership evaluated the future deployment of its idle fleet under current market conditions and determined to retire and either sell or re-utilize the key components of 166 compressor units, or approximately 58,000 horsepower, that were previously used to provide services in the Partnership’s business. This compression equipment was written down to its respective estimated salvage value, measured using quoted market prices, or the estimated component value of the equipment the Partnership plans to use. As a result of the Partnership’s decision to retire, sell or re-utilize these compressor units, management performed an impairment review and based on that review, recorded a $26.8 million impairment of long-lived assets in the three and six months ended June 30, 2015. The Partnership did not record impairment of long-lived assets in the three and six months ended June 30, 2014.

Partners' Capital

(6) Partners’ Capital

As of August 3, 2015, USA Compression Holdings held 5,997,651 common units and 14,048,588 subordinated units and controlled the General Partner which held an approximate 1.6% general partner interest (the “General Partner’s Interest”) and the incentive distribution rights (“IDRs”). See the Unaudited Condensed Consolidated Statement of Changes in Partners’ Capital.

Subordinated Units

All of the subordinated units are held by USA Compression Holdings. Our limited partnership agreement (the “Partnership Agreement”) provides that, during the subordination period, the common units have the right to receive distributions of Available Cash from Operating Surplus (each as defined in the Partnership Agreement) each quarter in an amount equal to $0.425 per common unit (the “Minimum Quarterly Distribution”), plus any arrearages in the payment of the Minimum Quarterly Distribution from Operating Surplus on the common units from prior quarters, before any distributions of Available Cash from Operating Surplus may be made on the subordinated units. These units are deemed “subordinated” because for a period of time, referred to as the subordination period, the subordinated units will not be entitled to receive any distributions from Operating Surplus until the common units have received the Minimum Quarterly Distribution plus any arrearages from prior quarters. The practical effect of the subordinated units is to increase the likelihood that during the subordination period there will be Available Cash from Operating Surplus to be distributed on the common units. The subordination period will end on the first business day after the Partnership has earned and paid at least (i) $1.70 (the Minimum Quarterly Distribution on an annualized basis) on each outstanding unit and the corresponding distribution on the General Partner’s Interest, for each of three consecutive, non-overlapping four-quarter periods ending on or after December 31, 2015 or (ii) $2.55 (150.0% of the annualized Minimum Quarterly Distribution) on each outstanding unit and the corresponding distributions on the General Partner’s Interest and the related distribution on the IDRs for the four-quarter period immediately preceding that date. When the subordination period ends, all subordinated units will convert into common units on a one-for-one basis, and all common units thereafter will no longer be entitled to arrearages.

Cash Distributions

The Partnership has declared quarterly distributions per unit to limited partner unitholders of record, including holders of common and subordinated units, and distributions paid to the General Partner, including the General Partner’s Interest and IDRs, as follows (dollars in millions, except distribution per unit):


	Distribution per		Amount Paid to		Amount Paid to		Amount Paid to
	Limited Partner		Common		Subordinated		General		Total
Payment Date	Unit		Unitholders		Unitholder		Partner		Distribution
May 15, 2014	$	0.49	$	11.8	$	6.9	$	0.4	$	19.1
August 14, 2014		0.50		15.1		7.0		0.5		22.6
November 14, 2014		0.505		15.5		7.1		0.5		23.1
February 13, 2015		0.51		16.0		7.2		0.5		23.7
May 15, 2015		0.515		16.6		7.2		0.6		24.4

Dividend Reinvestment Program

During the six months ended June 30, 2015 and June 30, 2014, distributions of $27.0 million and $25.8 million, respectively, were reinvested under the distribution reinvestment plan (the “DRIP”) resulting in the issuance of 1.3 million and 0.9 million common units, respectively. Such distributions are treated as non-cash transactions in the accompanying Unaudited Condensed Consolidated Statements of Cash Flows. After taking into account the number of common units issued under the DRIP through June 30, 2015, we have the capacity to issue an additional 3.8 million common units under the DRIP.

Issuance of Equity in Private Placement

On May 21, 2015, we issued 34,921 common units in a private placement to Argonaut for $0.7 million in a transaction that was exempt from registration under Section 4(a)(2) of the Securities Act. We used the proceeds from the private placement for general partnership purposes. There were no other unregistered sales of securities during the three and six months ended June 30, 2015.

Announced Quarterly Distribution

On July 23, 2015, the Partnership announced a cash distribution of $0.525 per unit on its common and subordinated units. The distribution will be paid on August 14, 2015 to unitholders of record as of the close of business on August 4, 2015. USA Compression Holdings, the owner of approximately 43% of the Partnership’s outstanding limited partner interests, and Argonaut and certain of its related parties, the owners of approximately 17% of the Partnership’s outstanding limited partner interests, each have elected to reinvest all of this distribution with respect to their units pursuant to the DRIP (other than the 34,921 units recently acquired by Argonaut).

Earnings Per Common and Subordinated Unit

The computations of earnings per common unit and subordinated unit are based on the weighted average number of common units and subordinated units, respectively, outstanding during the applicable period. The subordinated units and the General Partner’s Interest (including its IDRs) meet the definition of participating securities as defined by the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 260 Earnings Per Share; therefore, the Partnership is required to use the two-class method in the computation of earnings per unit. Basic earnings per common and subordinated unit are determined by dividing net income (loss) allocated to the common and subordinated units, respectively, after deducting the amount allocated to the General Partner (including distributions to the General Partner on its IDRs), by the weighted average number of outstanding common and subordinated units, respectively, during the period. Net income (loss) is allocated to the common units, subordinated units and the General Partner based on their respective shares of the distributed and undistributed earnings for the period. To the extent cash distributions exceed net income (loss) for the period, the excess distributions are allocated to all participating units outstanding based on their respective ownership percentages. Diluted earnings per unit are computed using the treasury stock method, which considers the potential issuance of limited partner units associated with the LTIP. Unvested phantom units are not included in basic earnings per unit, as they are not considered to be participating securities, but are included in the calculation of diluted earnings per unit. For the three and six months ended June 30, 2015, approximately 74,000 and 106,000 incremental phantom units, respectively, were excluded from the calculation of diluted units because the impact was anti-dilutive.

Incentive Distribution Rights

The General Partner holds all of the IDRs. The following table illustrates the percentage allocations of Available Cash from Operating Surplus between the unitholders and the General Partner based on the specified target distribution levels. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of the General Partner and the unitholders in any Available Cash from Operating Surplus the Partnership distributes up to and including the corresponding amount in the column “Total Quarterly Distribution Per Unit.” The percentage interests shown for our unitholders and the General Partner for the minimum quarterly distribution are also applicable to quarterly distribution amounts that are less than the minimum quarterly distribution. The percentage interests set forth below for the General Partner include its General Partner’s Interest, and assume the General Partner has contributed any additional capital necessary to maintain its General Partner’s Interest, the General Partner has not transferred the IDRs and there are no arrearages on common units.

Recent Accounting Pronouncement

(9) Recent Accounting Pronouncement

In April 2015, the FASB issued an Accounting Standards Update (“ASU”) that clarified when fees paid in a cloud computing arrangement pertain to the acquisition of a software license and/or services. When a cloud computing arrangement includes a license of software, the fee attributable to the software license portion of the arrangement will be capitalized when the criteria for capitalization of internal-use software are met. When a cloud computing arrangement does not include a license of software, the arrangement will be treated as a service contract and the cost will be expensed as the services are received. This ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2015. Early adoption is permitted and entities may elect to adopt this ASU either prospectively, for all arrangements entered into or materially modified after the effective date, or retrospectively. The Partnership is currently evaluating the impact, if any, of this ASU on its consolidated financial statements.

Also in April 2015, the FASB issued an ASU that simplified the presentation of debt issuance costs. The standard states:

Deferred debt issuance costs will, instead of being reported as an asset, be deducted from the gross carrying amount of the debt to which it relates.

Amortization of debt issuance costs will be reported as interest expense.

The ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2015. Early adoption is permitted. At the June 18, 2015 meeting of the FASB’s Emerging Issues Task Force, the SEC staff announced that it would not object to an entity’s deferral and presentation of such costs incurred in connection with revolving-debt arrangements as an asset. As all of the Partnership’s debt issuance costs are associated with the revolving credit facility, this ASU currently has no impact on the Partnership’s consolidated financial statements.

In July 2015, the FASB agreed to defer by one year the mandatory effective date of its revenue recognition standard to annual and interim periods in fiscal years beginning after December 15, 2017, but will also provide entities the option to adopt it as of the original effective date. The option to use either a retrospective or cumulative-effect transition method will not change. The Partnership is currently evaluating the impact, if any, of this ASU on its consolidated financial statements.

Also in July 2015, the FASB issued an ASU that changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. The ASU requires prospective adoptions for inventory measurements for annual and interim periods in fiscal years beginning after December 15, 2016. Early adoptions is permitted. The Partnership is currently evaluating the impact, if any, of this ASU on its consolidated financial statements.

- Definition
