Organization and Summary of Significant Accounting Policies

Organization and Summary of Significant Accounting Policies

(1) Organization and Summary of Significant Accounting Policies

(a) Organization

Unless otherwise indicated, the terms “our”, “we”, “us”, “the Partnership” and similar language refer to USA Compression Partners, LP, collectively with its operating subsidiaries. We are a Delaware limited partnership. USA Compression GP, LLC, a Delaware limited liability company, serves as our general partner and is referred to herein as the “General Partner”. Our General Partner was owned by USA Compression Holdings, LLC (“USA Compression Holdings”) until April 2, 2018. See Note 12 for a description of the April 2, 2018 transactions. Through our operating subsidiaries, we provide compression services under term contracts with customers in the natural gas and crude oil industries, using natural gas compression packages that we design, engineer, own, operate and maintain. We provide compression services in a number of shale plays throughout the United States, including the Utica, Marcellus, Permian Basin, Delaware Basin, Eagle Ford, Mississippi Lime, Granite Wash, Woodford, Barnett, Haynesville, Niobrara and Fayetteville shales.

The accompanying unaudited condensed consolidated financial statements include the accounts of the Partnership and its operating subsidiaries, all of which are wholly owned by us.

Net income (loss) is allocated to our general and limited partners using the two-class income allocation method. All intercompany balances and transactions have been eliminated in consolidation. Our common units representing limited partner interests in the Partnership trade on the New York Stock Exchange under the ticker symbol “USAC”.

Our ownership structure was as follows:


	March 31, 2018
	USA
	Compression
	Holdings		Public		Total
General partner interest	1.2	%	—		1.2	%
Limited partner interest	39.7	%	59.1	%	98.8	%
Total (1)	40.9	%	59.1	%	100.0	%

(1)

See Note 12 for changes to the ownership structure on April 2, 2018.

(b) Basis of Presentation

Our accompanying unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements included in our annual report on Form 10-K for the year ended December 31, 2017 filed on February 13, 2018 (our “2017 Annual Report”). In the opinion of our management, such financial information reflects all normal recurring adjustments necessary for a fair presentation of these interim unaudited condensed consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”). Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018. 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 U.S. Securities and Exchange Commission (the “SEC”). Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2017 contained in our 2017 Annual Report.

Our unaudited condensed consolidated financial statements 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 existed at the date of the unaudited condensed consolidated financial statements. Although these estimates were based on management’s available knowledge of current and expected future events, actual results could differ from these estimates.

(d) Inventory

Inventory consists of serialized and non-serialized parts used primarily in the repair of compression units. All inventory is stated at the lower of cost or net realizable value. The cost of serialized parts inventory is determined using the specific identification cost method, while the cost of non-serialized parts inventory is determined using the weighted average cost method. Purchases of these assets are considered operating activities on the Unaudited Condensed Consolidated Statements of Cash Flows.

Components of inventory are as follows (in thousands):


	March 31, 2018		December 31, 2017
Serialized parts	$	16,270	$	16,413
Non-serialized parts		18,130		17,181
Total Inventory, gross		34,400		33,594
Less: obsolete and slow moving reserve		(150)		(150)
Total Inventory, net	$	34,250	$	33,444

(e) Identifiable Intangible Assets

Identifiable intangible assets, net consisted of the following (in thousands):


	Customer
	Relationships		Trade Names		Total
Net Balance at December 31, 2017	$	60,448	$	11,232	$	71,680
Amortization Expense		(683)		(156)		(839)
Net Balance at March 31, 2018	$	59,765	$	11,076	$	70,841

Identifiable intangible assets are recorded at cost and 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 our future cash flows. The estimated useful lives range from 20 to 30 years. Accumulated amortization of intangible assets was $24.4 million and $23.5 million as of March 31, 2018 and December 31, 2017, respectively.

We assess identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. We did not record any impairment of identifiable intangible assets for the three months ended March 31, 2018 or 2017.

(f) Property and Equipment

Property and equipment are carried at cost except for (i) certain acquired assets which are recorded at fair value on their respective acquisition dates and (ii) impaired assets which are recorded at fair value on the last impairment evaluation date for which an adjustment was required. Overhauls and major improvements that increase the value or extend the life of compression 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, acquired new		25 years
Compression equipment, acquired used		9 - 25 years
Furniture and fixtures		7 years
Vehicles and computer equipment		3 - 7 years
Leasehold improvements		5 years

When property and equipment is retired or sold, its carrying value and the related accumulated depreciation are removed from our accounts and any associated gains or losses are recorded on our statements of operations in the period of sale or disposition.

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

(g) Impairment 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. We test long-lived assets for impairment when events or circumstances indicate that the assets’ carrying value may not be recoverable or will no longer be utilized in the operating fleet. The most common circumstance requiring compression units to be tested for impairment is when idle units do not meet the performance characteristics of our active revenue generating horsepower.

We did not record any impairment of long-lived assets during the three months ended March 31, 2018. During the three months ended March 31, 2017, we evaluated the future deployment of our idle fleet under then-current market conditions and determined to retire, sell or re-utilize key components of two compressor units, or 2,760 horsepower, that were previously used to provide services in our business. The primary cause of impairment was due to estimated significant repair costs from previous damage to the equipment. These compressor units were written down to their respective estimated salvage value, if any. As a result of our decision to retire, sell or re-utilize key components of these compressor units, management performed an impairment review and recorded $1.1 million of impairment of long-lived assets in the three months ended March 31, 2017.

(h) 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 we use 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 we have 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 March 31, 2018 and December 31, 2017, our 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 maturities. The carrying amount of our revolving credit facility approximates fair value due to the floating interest rates associated with the debt. The carrying amount of our senior notes approximates fair value as the notes were issued on March 23, 2018. See Note 6 for additional information on the senior notes.

(i) Operating Segment

We operate in a single business segment, the compression services business.

Bridge Loans

In connection with the CDM Acquisition (as defined in Note 12), on January 15, 2018, we entered into a commitment letter (the “Bridge Commitment”) with JPMorgan Chase Bank, N.A. and Barclays Bank PLC, as modified by the joinder to commitment letter and bridge fee letter entered into by the Partnership, JPMorgan Chase Bank, N.A. and Barclays Bank PLC with each of Regions Bank, Royal Bank of Canada, Wells Fargo Bank, N.A., MUFG Union Bank, N.A., a member of MUFG, a global financial group, The Bank of Nova Scotia and SunTrust Bank and certain affiliates of such parties (the “Commitment Letter”). The Commitment Letter provided for senior unsecured bridge loans in an aggregate amount up to $725 million (the “Bridge Loans”). The Bridge Loans were available to backstop a portion of the CDM Acquisition purchase price that we ultimately funded with the net proceeds from the senior notes.

In connection with entering into the Bridge Commitment, we incurred certain transaction fees in the amount of $18.4 million which are reported within Selling, general and administrative expense on the Unaudited Condensed Consolidated Statements of Operations for the three months ended March 31, 2018.

Revolving Credit Facility

On January 29, 2018, we entered into a fourth amendment to our revolving credit facility to, among other things, (i) permit us to consummate the CDM Acquisition, (ii) permit us to incur up to $800 million in aggregate amount of indebtedness with respect to the Bridge Loans described above or other long-term indebtedness such as the senior notes, (iii) increase from $20 million to $100 million the minimum borrowing base availability under the revolving credit facility as a condition to making distributions of available cash to unitholders, and (iv) amend certain other provisions of the revolving credit facility, all as more fully set forth in the amendment documents.

In connection with entering into the fourth amendment, we paid certain amendment fees to the lenders party thereto in the amount of $0.8 million during the three months ended March 31, 2018. These fees were capitalized to loan costs and will be amortized over the term of the revolving credit facility. No such fees were paid during the three months ended March 31, 2017.

As of March 31, 2018, we were in compliance with all of our covenants under our revolving credit facility.

As of March 31, 2018, we had outstanding borrowings under our revolving credit facility of $819.1 million, $273.9 million of borrowing base availability and, subject to compliance with the applicable financial covenants, available borrowing capacity of $37.0 million. Our interest rate in effect for all borrowings under our revolving credit facility as of March 31, 2018 and December 31, 2017 was 4.75% and 3.46%, respectively, with a weighted average interest rate of 3.67% and 2.98% during the three months ended March 31, 2018 and 2017, respectively. There were no letters of credit issued as of March 31, 2018 or 2017.

In the event that any of the operating subsidiaries guarantees any series of the debt securities as described in our registration statements on Form S-3, such guarantees will be full and unconditional and made on a joint and several basis for the benefit of each holder and the Trustee. However, such guarantees will be subject to release, subject to certain limitations, as follows (i) upon the sale, exchange or transfer, whether by way of a merger or otherwise, to any Person that is not our affiliate, of all of our direct or indirect limited partnership or other equity interest in such Subsidiary Guarantor; or (ii) upon our or USA Compression Finance Corp.’s (together, the “Issuers”) delivery of a written notice to the Trustee of the release or discharge of all guarantees by such Subsidiary Guarantor of any Debt of the Issuers other than obligations arising under the indenture governing such debt and any debt securities issued under such indenture, except a discharge or release by or as a result of payment under such guarantees. Capitalized terms used but not defined in this paragraph are defined in the Form of Indenture filed as exhibit 4.1 to such registration statement.

Certain of our operating subsidiaries are borrowers under our revolving credit facility, and we are a guarantor of the revolving credit facility.

Our operating subsidiaries and USA Compression Finance Corp. (“Finance Corp”) are our only existing subsidiaries. We have no assets or operations independent of our subsidiaries, and there are no significant restrictions upon our ability to obtain funds from our subsidiaries by dividend or loan. None of the assets of our subsidiaries represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended.

On April 2, 2018, our revolving credit facility was amended and restated with a maturity date of April 2, 2023. See Note 12(e) for additional information.

Senior Notes

On March 23, 2018, we co-issued with Finance Corp $725.0 million aggregate principal amount of senior notes that mature on April 1, 2026. The notes accrue interest from March 23, 2018 at the rate of 6.875% per year. Interest on the notes will be payable semi-annually in arrears on each April 1 and October 1, commencing on October 1, 2018.

Prior to April 1, 2021, we may redeem up to 35% of the aggregate principal amount of the notes at a redemption price equal to 106.875% of the principal amount, plus accrued and unpaid interest, if any, to the redemption date, in an amount not greater than the net proceeds from one or more equity offerings, provided that at least 65% of the aggregate principal amount of the notes remain outstanding immediately after the occurrence of such redemption (excluding notes held by us and our subsidiaries) and redemption occurs within 180 days of the date of the closing of such equity offering. Prior to April 1, 2021, we may redeem all or a part of these notes at a redemption price equal to the sum of (i) the principal amount thereof, plus (ii) a make-whole premium at the redemption date, plus accrued and unpaid interest, if any, to the redemption date. On or after April 1, 2021, we may redeem all or a part of these notes at redemption prices (expressed as percentages of principal amount) equal to 105.156% for the twelve-month period beginning on April 1, 2021, 103.438% for the twelve-month period beginning on April 1, 2022, 101.719% for the twelve-month period beginning on April 1, 2023 and 100.00% beginning on April 1, 2024 and at any time thereafter, plus accrued and unpaid interest, if any, to the applicable redemption date. If we experience a change of control followed by a ratings decline, unless we have previously exercised or concurrently exercise the right to redeem the notes (as described above), we may be required to offer to repurchase the notes at a purchase price equal to 101% of the principal amount repurchased, plus accrued and unpaid interest, if any, to the repurchase date.

There are no financial maintenance covenants associated with the senior notes.

In connection with issuing the senior notes, we incurred certain issuance costs in the amount of $17.3 million which will be amortized over the term of the senior notes using the effective interest method and is reported within Long-term debt, net on the Unaudited Condensed Consolidated Balance Sheets as of March 31, 2018.

The senior notes are guaranteed (the “Guarantees”), jointly and severally, on a senior unsecured basis by our existing subsidiaries (other than Finance Corp.) and each of our future restricted subsidiaries that either borrows under, or guarantees, our revolving credit facility or guarantees certain of our other indebtedness (collectively, the “Guarantors”). The senior notes and the Guarantees are the Guarantors’ and our general unsecured obligations and rank equally in right of payment with all of the Guarantors’ and our existing and future senior indebtedness and senior to all of the Guarantors’ and our future subordinated indebtedness, if any. The senior notes and the Guarantees are effectively subordinated in right of payment to all of the Guarantors’ and our existing and future secured debt, including debt under our revolving credit facility and guarantees thereof, to the extent of the value of the assets securing such debt, and are structurally subordinated to all indebtedness of any of our subsidiaries that do not guarantee the notes.

Common Units and General Partner Interest

As of March 31, 2018, we had 62,443,593 common units outstanding. USA Compression Holdings held 25,092,196 common units as of March 31, 2018 and controlled our General Partner, which held an approximate 1.2% 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. See Note 12 for changes to the ownership structure on April 2, 2018.

Cash Distributions

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


	Distribution per		Amount Paid to		Amount Paid to		Amount Paid to
	Limited Partner		Common		General		Phantom		Total
Payment Date	Unit		Unitholders		Partner		Unitholders		Distribution
February 14, 2017	$	0.525	$	31.9	$	0.7	$	0.8	$	33.4
May 12, 2017	$	0.525	$	32.1	$	0.7	$	0.6	$	33.4

February 14, 2018	$	0.525	$	32.7	$	0.8	$	0.8	$	34.3

Announced Quarterly Distribution

On April 19, 2018, we announced a cash distribution of $0.525 per unit on our common units. The distribution will be paid on May 11, 2018 to unitholders of record as of the close of business on May 1, 2018.

Distribution Reinvestment Plan

During the three months ended March 31, 2018 and 2017, distributions of $0.2 million and $4.1 million, respectively, were reinvested under the DRIP resulting in the issuance of 9,571 and 221,693 common units, respectively. Such distributions are treated as non-cash transactions in the accompanying Unaudited Condensed Consolidated Statements of Cash Flows.

Earnings Per Unit

The computation of earnings per unit is based on the weighted average number of units outstanding during the applicable period. Basic earnings per unit is determined by dividing net income (loss) allocated to the units after deducting the amount allocated to our General Partner (including distributions to our General Partner on our General Partner’s Interest and its IDRs, if any), by the weighted average number of outstanding units during the period. Net income (loss) is allocated to the units and our General Partner’s Interest (including its IDRs) 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 our long-term incentive plan. 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. Incremental unvested phantom units outstanding represent the only difference between our basic and diluted weighted average common units outstanding during the three months ended March 31, 2017. For the three months ended March 31, 2018, approximately 324,000 incremental unvested phantom units were excluded from the calculation of diluted earnings per unit because the impact was anti-dilutive.

Incentive Distribution Rights

Prior to April 2, 2018, our General Partner held all of our IDRs. The IDRs represented the right to receive an increasing percentage of our quarterly distributions of available cash from operating surplus after the minimum quarterly distribution and the target distribution levels had been achieved. See Note 12(c) for additional information on the Equity Restructuring Agreement that converted the General Partner’s Interest into a non-economic general partner interest and cancelled the IDRs on April 2, 2018.

The following table illustrates the percentage allocations of Available Cash from Operating Surplus between our unitholders and our General Partner based on the specified target distribution levels that were applicable prior to April 2, 2018. The amounts set forth under “Marginal Percentage Interest in Distributions” are the percentage interests of our General Partner and our unitholders in any Available Cash from Operating Surplus we distribute up to and including the corresponding amount in the column “Total Quarterly Distribution Per Unit.” The percentage interests shown for our unitholders and our 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 our General Partner include its General Partner’s Interest, and assume our General Partner has contributed any additional capital necessary to maintain its General Partner’s Interest and our General Partner has not transferred our IDRs.


		Marginal Percentage Interest
	Total Quarterly	in Distributions

Revenue Recognition

Revenue Recognition

(8) Revenue Recognition

Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of our services or goods. Revenue is measured at the amount of consideration we expect to receive in exchange for providing services or transferring goods. Sales taxes incurred on behalf of, and passed through to, customers are excluded from revenue. Incidental items, if any, that are immaterial in the context of the contract are recognized as expense.

Adoption of ASC Topic 606, "Revenue from Contracts with Customers"

On January 1, 2018, we adopted Accounting Standards Codification Topic 606 (“ASC Topic 606”) using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under ASC Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under ASC Topic 605.

We identified no material impact on our historical revenues upon initial application of ASC Topic 606, and as such have not recognized any cumulative catch-up effect to the opening balance of our partners’ capital as of January 1, 2018. Additionally, the application of ASC Topic 606 has no material impact on any current financial statement line items.

The following table disaggregates our revenue by type of service (in thousands):

Contract operations revenue

Revenue from contracted compression, station and maintenance services is recognized ratably under our fixed-fee contracts over the term of the contract as services are provided to our customers. Initial contract terms typically range from six months to five years, however we typically continue to provide compression services at a specific location beyond the initial contract term, either through contract renewal or on a month-to-month or longer basis. We primarily enter into take-or-pay contracts whereby our customers are required to pay our monthly fee even during periods of limited or disrupted throughput. Services generally are billed monthly, one month in advance of the commencement of the service month, except for certain customers who are billed at the beginning of the service month, and payment is generally due 30 days after receipt of our invoice. Amounts invoiced in advance are recorded as deferred revenue on our Unaudited Condensed Consolidated Balance Sheet until earned, at which time they are recognized as revenue. The amount of consideration we receive and revenue we recognize is based upon the fixed fee rate stated in each service contract.

Our contracts with customers may include multiple performance obligations. For such arrangements, we allocate revenues to each performance obligation based on its relative standalone service fee. We generally determine standalone service fees based on the service fees charged to customers or using expected cost plus margin.

The majority of our service performance obligations are satisfied over time as services are rendered at selected customer locations on a monthly basis and based upon specific performance criteria identified in the applicable contract. The monthly service for each location is substantially the same service month to month and is promised consecutively over the service contract term. We measure progress and performance of the service consistently using a straight-line, time-based method as each month passes, because our performance obligations are satisfied evenly over the contract term as the customer simultaneously receives and consumes the benefits provided by our service.

There are typically no material obligations for returns or refunds. Our standard contracts typically do not have material variable consideration or non-cash consideration.

Retail parts and services revenue

Retail parts and service revenue is earned primarily on freight and crane charges that are directly reimbursable by our customers and maintenance work on units at our customers’ locations that are outside the scope of our core maintenance activities. Revenue from retail parts and services is recognized at the point in time the part is transferred or service is provided and control is transferred to the customer. At such time, the customer has the ability to direct the use of the benefits of such part or service after we have performed. We bill upon completion of the service or transfer of the parts, and payment is generally due 30 days after receipt of our invoice. The amount of consideration we receive and revenue we recognize is based upon the invoice amount. There are typically no material obligations for returns, refunds, or warranties. Our standard contracts typically do not have material variable consideration or non-cash consideration.

Station installations revenue

Revenue from station installations is earned on stations we build on behalf of, and sell to, our customers and such revenue is recognized over time as services are provided. A station typically consists of compressor equipment combined with other equipment ancillary to compression, such as slug catchers, pipe racks, tanks, dehydration, valves, and control rooms, which together assist in the treating, processing, pressurization and transportation of natural gas. Our performance enhances an asset that the customer controls and our performance does not create an asset with alternative use to us. Revenue is recognized over time based on the progress-toward-completion method and progress is measured using the efforts-expended input method. In applying the efforts-expended input method, we use the percentage of total completed workflows to date relative to estimated total workflows to determine the amount of revenue and profit to recognize for each contract. The amount of consideration we receive and revenue we recognize varies in accordance with each contractual agreement negotiated with our customers.

The progress-toward-completion method of revenue recognition requires us to make estimates of contract revenues and costs to complete our projects. In making such estimates, management judgments are required to evaluate significant assumptions including the cost of materials and labor, expected labor productivity, the impact of potential variances in schedule completion, the amount of net contract revenues and the impact of any penalties, claims, change orders, or performance incentives.

Our payment terms vary in accordance with each contractual agreement negotiated with our customers. The term between invoicing and when payment is due is not significant. We retain the right to payment for performance completed to date at any point during the contract term. There are no material obligations for returns, refunds, or warranties.

Contract assets and trade accounts receivable

We record contract assets when we have completed performance under a contract but our right to consideration is not yet unconditional. We had no contract assets as of March 31, 2018 or December 31, 2017. Trade accounts receivable are recorded when our right to consideration becomes unconditional. There were no significant changes to our trade accounts receivable balances due to business combinations, modifications or contract adjustments, or changes in time frame for a right to consideration to become unconditional during the period.

Deferred revenue

We record deferred revenue when cash payments are received or due in advance of our performance. The increase in the deferred revenue balance for the three months ended March 31, 2018 is primarily driven by cash payments received or due in advance of satisfying our performance obligations under a contract, offset by $21.6 million of revenues recognized that were included in the deferred revenue balance as of December 31, 2017. There was no significant change to our deferred revenue balance as a result of changes in time frame for a performance obligation to be satisfied during the period.

Practical expedients and exemptions

We have elected to apply the practical expedient in ASC 606-10-50-14 and as such do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

Costs to fulfill a contract

We sometimes incur non-reimbursable costs for loading, transporting and unloading equipment to and from our storage locations and customer locations. We defer and amortize these costs using the straight-line method over the life of the contract. We recognized $0.2 million and $0.1 million of costs to fulfill a contract within Prepaid expenses on the Unaudited Condensed Consolidated Balance Sheets as of March 31, 2018 and December 31, 2017, respectively, and $0.1 million in amortization expense of costs to fulfill a contract within Cost of operations, exclusive of depreciation and amortization on the Unaudited Condensed Consolidated Statements of Operations for the three months ended March 31, 2018. Amortization expense was zero for the three months ended March 31, 2017.

Subsequent Events	3 Months Ended

Subsequent Events
Subsequent Events	(12) Subsequent Events (a) CDM Acquisition Closes On April 2, 2018, we completed the previously announced acquisition (the “CDM Acquisition”) of all of the issued and outstanding membership interests of CDM Resource Management LLC, a Delaware limited liability company (“CDM”), and CDM Environmental & Technical Services LLC, a Delaware limited liability company (“CDM E&T”), from Energy Transfer Partners, L.P., a Delaware limited partnership (“ETP”), in exchange for aggregate consideration of approximately $1.7 billion, consisting of (i) 19,191,351 common units, (ii) 6,397,965 Class B units representing limited partner interests in us (“Class B Units”) and (iii) $1.232 billion in cash (including estimated customary closing adjustments). The purchase price was determined based on arm’s length negotiations. Prior to the CDM Acquisition and related transactions, there were no material relationships between ETP and its affiliates, on the one hand, and the Partnership or any of its affiliates, directors, officers or any associate of such directors or officers, on the other hand. Due to the multiple facets of this acquisition, which was executed through a series of transactions described below, we are still evaluating which accounting method to use and which entity will serve as predecessor for financial reporting purposes. Further, the valuation of our assets is currently in process and we do not have preliminary estimates available. As such, the disclosure requirements in ASC 805-10-50-2 and ASC 805-30-50-1 cannot be made as of the time of filing this report. (b) GP Purchase Agreement On April 2, 2018 and in connection with the closing of the CDM Acquisition, pursuant to that certain Purchase Agreement (the “GP Purchase Agreement”), dated as of January 15, 2018, by and among Energy Transfer Equity, L.P. (“ETE”), Energy Transfer Partners, L.L.C. (together with ETE, the “GP Purchasers”), USAC Holdings and, solely for certain purposes therein, R/C IV USACP Holdings, L.P. and ETP, the GP Purchasers acquired from USAC Holdings (i) all of the outstanding limited liability company interests in the General Partner and (ii) 12,466,912 Common Units (the “GP Purchase”) for cash consideration equal to $250 million. (c) Equity Restructuring Agreement On April 2, 2018 and in connection with the closing of the CDM Acquisition, we consummated the transactions contemplated by the Equity Restructuring Agreement (the “Equity Restructuring Agreement”) dated January 15, 2018, by and among us, our General Partner and ETE, including, among other things, the cancellation of the IDRs (the “Cancellation”) and conversion of our General Partner’s Interest into a non-economic general partner interest (the “Conversion” and, together with the Cancellation, the “Restructuring”), in exchange for our issuance of 8,000,000 common units to the General Partner. In addition, at any time after one year following the closing, ETE will have the right to contribute (or cause any of its subsidiaries to contribute) to us all of the outstanding equity interests in any of its subsidiaries that owns the general partner interest in us in exchange for $10 million (the “GP Contribution”); provided that the GP Contribution will occur automatically if at any time following the closing (i) ETE or one of its subsidiaries (including ETP) owns, directly or indirectly, the general partner interest in us and (ii) ETE and its subsidiaries (including ETP) collectively own less than 12,500,000 common units. (d) Series A Preferred Unit and Warrant Private Placement On April 2, 2018, we consummated the transactions contemplated by the Series A Preferred Unit and Warrant Purchase Agreement (the “Purchase Agreement”), dated January 15, 2018, with certain investment funds managed or sub-advised by EIG Global Energy Partners (“EIG”) and other investment vehicles unaffiliated with EIG (collectively, the “Purchasers”) to issue and sell in a private placement (the “Private Placement”) $500 million in the aggregate of (i) newly authorized and established Series A Preferred Units representing limited partner interests in us (the “Preferred Units”) and (ii) warrants to purchase common units (the “Warrants”). Pursuant to the terms of the Purchase Agreement, on April 2, 2018, we issued 500,000 Preferred Units to the Purchasers at a price of $1,000 per Preferred Unit, less a 1.0% structuring and origination fee, for total net proceeds, before expenses, of $495 million. In addition, we paid a 1.0% commitment fee to the Purchasers at the closing and reimbursed the Purchasers $0.4 million for certain expenses incurred in connection with the Private Placement. We also issued two tranches of Warrants to the Purchasers, which included Warrants to purchase 5,000,000 common units with a strike price of $17.03 per unit and Warrants to purchase 10,000,000 common units with a strike price of $19.59 per unit. The Warrants may be exercised by the holders thereof at any time beginning on the one year anniversary of the closing date and before the tenth anniversary of the closing date. Upon exercise of the Warrants, we may, at our option, elect to settle the Warrants in common units on a net basis. (e) Credit Facility Amendment and Restatement On April 2, 2018, we entered into the Sixth Amended and Restated Credit Agreement (the “Sixth A&R Credit Agreement”) by and among the Partnership, as borrower, USAC OpCo 2, LLC, USAC Leasing 2, LLC, USA Compression Partners, LLC, USAC Leasing, LLC, CDM, CDM E&T and USA Compression Finance Corp., the lenders party thereto from time to time, JPMorgan Chase Bank, N.A., as agent and an LC issuer, JPMorgan Chase Bank, N.A., Barclays Bank PLC, Regions Capital Markets, a division of Regions Bank, RBC Capital Markets and Wells Fargo Bank, N.A., as joint lead arrangers and joint book runners, Barclays Bank PLC, Regions Bank, RBC Capital Markets and Wells Fargo Bank, N.A., as syndication agents, and MUFG Union Bank, N.A., SunTrust Bank and The Bank of Nova Scotia, as senior managing agents. The Sixth A&R Credit Agreement amended and restated that certain Fifth Amended and Restated Credit Agreement, dated as of December 13, 2013, as amended (the “Fifth A&R Credit Agreement”). The Sixth A&R Credit Agreement amended the Fifth A&R Credit Agreement to, among other things, (i) increase the borrowing capacity under the revolving credit facility from $1.1 billion to $1.6 billion (subject to availability under a borrowing base), (ii) extend the termination date (and the maturity date of the obligations thereunder) from January 6, 2020 to April 2, 2023, (iii) subject to the terms of the Sixth A&R Credit Agreement, permit up to $400.0 million of future increases in borrowing capacity, (iv) modify the leverage ratio covenant to be 5.75 to 1.0 through the end of the fiscal quarter ending March 31, 2019, 5.5 to 1.0 through the end of the fiscal quarter ending December 31, 2019, and 5.0 to 1.0 thereafter and (v) increase the applicable margin for eurodollar borrowings to range from 2.00% to 2.75%, depending on our leverage ratio, all as more fully set forth in the Sixth A&R Credit Agreement. As of the close of business on April 2, 2018, we had $899.5 million of outstanding borrowings and no outstanding letters of credit under the Sixth A&R Credit Agreement. In connection with entering into the Sixth A&R Credit Agreement, we paid certain upfront fees and arrangement fees to the arrangers, syndication agents and senior managing agents of the Sixth A&R Credit Agreement. Amounts borrowed and repaid under the Sixth A&R Credit Agreement may be re-borrowed. (f) Phantom Units Accelerated Vesting On April 2, 2018 and in connection with the closing of the CDM Acquisition, and pursuant to the change in control provisions of our outstanding phantom unit awards, all of the performance-based phantom units granted during 2018, 2017 and 2016, and outstanding as of April 2, 2018, vested immediately upon the change in control event at 100% of the target level. In addition, all outstanding time-based phantom units held by our CEO vested immediately upon the change in control event. As such, 563,544 outstanding phantom unit awards vested resulting in $6.9 million of compensation expense that will be recognized during the three months ended June 30, 2018.

Trade Accounts Receivable	Mar. 31, 2018
Trade Accounts Receivable
Trade Accounts Receivable	(2) Trade Accounts Receivable Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts, which was $0.3 million and $0.4 million at March 31, 2018 and December 31, 2017, respectively, is our best estimate of the amount of probable credit losses included in our existing accounts receivable. We determine the allowance based upon historical write-off experience and specific customer circumstances. The determination of the allowance for doubtful accounts requires us to make estimates and judgments regarding our customers’ ability to pay amounts due. On an ongoing basis, we conduct an evaluation of the financial strength of our customers based on payment history, the overall business climate in which our customers operate and specific identification of customer bad debt and make adjustments to the allowance as necessary. Our evaluation of our customers’ financial strength is based on the aging of their respective receivables balance, customer correspondence, financial information and third-party credit ratings. Our evaluation of the business climate in which our customers operate is based on a review of various publicly-available materials regarding our customers’ industries, including the solvency of various companies in the industry. During the three months ended March 31, 2018, we reduced our allowance for doubtful accounts by $0.1 million due to write-offs of bad debt. During the three months ended March 31, 2017, we reduced our allowance for doubtful accounts by $0.1 million due to collections on accounts that had previously been reserved.

We recognized $21.0 million and $1.4 million of accrued transaction expenses as of March 31, 2018 and December 31, 2017, respectively. We recognized $20.0 million and $0.2 million of accrued compression equipment purchases as of March 31, 2018 and December 31, 2017, respectively. We recognized $3.3 million and $8.9 million of unit-based compensation liability as of March 31, 2018 and December 31, 2017, respectively. We recognized $3.1 million and $6.4 million of accrued payroll and benefits as of March 31, 2018 and December 31, 2017, respectively.

Transactions with Related Parties	(9) Transactions with Related Parties Jerry Peters, who served as a director of our General Partner from October 2017 through April 2, 2018, has served as a director of one of our customers since September 2012. During the three months ended March 31, 2018, we recognized $0.3 million in revenue from compression services from this customer. We provide compression services to entities affiliated with Riverstone/Carlyle Global Energy and Power Fund IV, L.P. (“Riverstone”), which owns a majority of the membership interests in USA Compression Holdings. USA Compression Holdings owned and controlled our General Partner and owned 39.7% of our limited partner interests until April 2, 2018. During the three months ended March 31, 2018 and 2017, we recognized $0.1 million and $0.2 million, respectively, in revenue from compression services from such affiliated entities. See Note 12 for changes to the ownership structure on April 2, 2018.

Commitments and Contingencies
Commitments and Contingencies	(10) Commitments and Contingencies (a) Major Customers We did not have revenue from any single customer representing 10% or more of total revenue for the three months ended March 31, 2018 or 2017. (b) Litigation From time to time, we and our subsidiaries may be involved in various claims and litigation arising in the ordinary course of business. In management’s opinion, the resolution of such matters is not expected to have a material adverse effect on our consolidated financial position, results of operations or cash flows. (c) Equipment Purchase Commitments Our future capital commitments are comprised of binding commitments under purchase orders for new compression units and serialized parts ordered but not received. The commitments as of March 31, 2018 were $128.7 million, which are expected to be settled throughout 2018 and early 2019. (d) Sales Tax Contingency Our compliance with state and local sales tax regulations is subject to audit by various taxing authorities. Certain taxing authorities have claimed that specific operational processes, which we and others in our industry regularly conduct, result in transactions that are subject to state sales taxes. We, and other entities in our industry, have disputed these claims based on existing tax statutes which provide for manufacturing exemptions on the transactions in question. We continue to work with the state taxing authority in providing them the documentation available to us to support the position we have taken with regard to the disputed transactions. We have recognized a liability of $0.1 million related to this issue; however, we believe it is reasonably possible that we could incur additional losses for this matter depending on whether the taxing authority accepts our documentation as sufficient to support our position that the disputed transactions are not taxable and the impact of any potential resulting litigation. Management estimates that the range of losses we could incur related to this matter is from $0.1 million to approximately $3.7 million. The upper end of this range assumes that we will be unable to apply the manufacturing exemption to any of the transactions in question, which management believes is remote.

Recent Accounting Pronouncements
Recent Accounting Pronouncements	(11) Recent Accounting Pronouncements In February 2016, the Financial Accounting Standards Board issued ASU 2016-02 ASC Topic 842 Leases (“ASC Topic 842”). ASC Topic 842 is a new leasing standard that increases transparency and comparability among organizations by, among other things, requiring lessees to recognize most lease assets and lease liabilities on the balance sheet and requiring both lessees and lessors to disclose expanded qualitative and quantitative information about leasing arrangements. This new leasing standard requires modified retrospective adoption for all leases existing at, or entered into after, the date of the initial application, with an option to use certain elective transition reliefs. ASC Topic 842 becomes effective for public business entities for annual and interim periods in fiscal years beginning after December 15, 2018. Early adoption of this standard is permitted. We expect to adopt this new standard on January 1, 2019. We are in the preliminary stages of the assessment phase and are in the process of identifying potential contracts and transactions subject to the provisions of the standard so that we may assess the financial impact of adopting this standard on our consolidated financial statements and related disclosures. Further, we are in the preliminary stages of assessing the changes in controls, processes and accounting policies that are necessary to implement this standard.
