Unless the context otherwise requires or where otherwise indicated, the terms “our,” “we,” “us,” “the Partnership” and similar language when used in the present or future tense and for periods on and subsequent to April 2, 2018 (the “Transactions Date”) refer to USA Compression Partners, LP, collectively with its consolidated operating subsidiaries, including the USA Compression Predecessor. Unless the context otherwise requires or where otherwise indicated, the term “USA Compression Predecessor,” as well as the terms “our,” “we,” “us” and “its” when used in a historical context or in reference to periods prior to the Transactions Date, refer to CDM Resource Management LLC and CDM Environmental & Technical Services LLC collectively, which has been deemed to be the predecessor of the Partnership for financial reporting purposes.

We are a Delaware limited partnership. Through our operating subsidiaries, we provide compression services under fixed-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 primarily 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.

USA Compression GP, LLC, a Delaware limited liability company, serves as our general partner and is referred to herein as the “General Partner.” The General Partner has been wholly owned by Energy Transfer Operating, L.P. (“ETO”) since October 2018, when Energy Transfer Equity, L.P. (“ETE”) and Energy Transfer Partners, L.P. (“ETP”) completed the merger of ETP with a wholly owned subsidiary of ETE in a unit-for-unit exchange (the “ETE Merger”). Following the closing of the ETE Merger, ETE changed its name to “Energy Transfer LP” (“ET LP”) and ETP changed its name to “Energy Transfer Operating, L.P.” Upon the closing of the ETE Merger, ETE contributed to ETO 100% of the limited liability company interests in the General Partner. References herein to “ETO” refer to ETP for periods prior to the ETE Merger and ETO following the ETE Merger, and references to “ET LP” refer to ETE for periods prior to the ETE Merger and ET LP following the ETE Merger.

The USA Compression Predecessor owned and operated a fleet of compressors used to provide natural gas compression services for customer specific systems. The USA Compression Predecessor also owned and operated a fleet of equipment used to provide natural gas treating services, such as carbon dioxide and hydrogen sulfide removal, cooling, and dehydration. The USA Compression Predecessor had operations located in Texas, Oklahoma, Louisiana, Arkansas, Pennsylvania, New Mexico, Colorado, Ohio, and West Virginia.

CDM Acquisition

On the Transactions Date, we consummated the transactions contemplated by the Contribution Agreement dated January 15, 2018, pursuant to which, among other things, we acquired all of the issued and outstanding membership interests of the USA Compression Predecessor from ETO (the “CDM Acquisition”) in exchange for aggregate consideration of approximately $1.7 billion, consisting of (i) 19,191,351 common units representing limited partner interests in us, (ii) 6,397,965 Class B units representing limited partner interests in us (“Class B Units”) and (iii) $1.2 billion in cash (including customary closing adjustments).

General Partner Purchase Agreement

On the Transactions Date, and in connection with the closing of the CDM Acquisition, we consummated the transactions contemplated by the Purchase Agreement dated January 15, 2018, by and among ET LP, Energy Transfer Partners, L.L.C., USA Compression Holdings, LLC (“USA Compression Holdings”) and, solely for certain purposes therein, R/C IV USACP Holdings, L.P. and ETO, pursuant to which, among other things, ET LP acquired from USA Compression Holdings (i) all of the outstanding limited liability company interests in the General Partner and (ii) 12,466,912 common units for cash consideration paid by ET LP to USA Compression Holdings equal to $250.0 million (the “GP Purchase”). Upon the closing of the ETE Merger, ET LP contributed all of the interests in the General Partner and the 12,466,912 common units to ETO.

Equity Restructuring Agreement

On the Transactions Date, and in connection with the closing of the CDM Acquisition, we consummated the transactions contemplated by the Equity Restructuring Agreement dated January 15, 2018, pursuant to which, among other things, the Partnership, the General Partner and ET LP agreed to cancel the Partnership’s Incentive Distribution Rights and convert the General Partner Interest (as defined in the Equity Restructuring Agreement) into a non-economic general partner interest, in exchange for the Partnership’s issuance of 8,000,000 common units to the General Partner (the “Equity Restructuring”).

The CDM Acquisition, GP Purchase and Equity Restructuring are collectively referred to as the “Transactions.”

Basis of Presentation

The Partnership

The unaudited condensed consolidated financial statements give effect to the business combination and the Transactions discussed above under the acquisition method of accounting, and the business combination has been accounted for in accordance with the applicable reverse merger accounting guidance. ET LP acquired a controlling financial interest in us through the acquisition of the General Partner. As a result, the USA Compression Predecessor is deemed to be the accounting acquirer of the Partnership because its ultimate parent company obtained control of the Partnership through its control of the General Partner. Consequently, the USA Compression Predecessor is deemed to be the predecessor of the Partnership for financial reporting purposes, and the historical financial statements of the Partnership reflect the USA Compression Predecessor for all periods prior to the closing of the Transactions, which occurred on the Transactions Date.

The USA Compression Predecessor’s assets and liabilities retained their historical carrying values. Additionally, the Partnership’s assets acquired and liabilities assumed by the USA Compression Predecessor in the business combination were recorded at their fair values measured as of the Transactions Date. The excess of the assumed purchase price of the Partnership over the estimated fair values of the Partnership’s net assets acquired was recorded as goodwill. The assumed purchase price and fair value of the Partnership was determined using acceptable fair value methods. Additionally, the USA Compression Predecessor was reflected at ET LP’s historical cost, and the difference between the consideration paid by the Partnership and ET LP’s historical carrying values (net book value) at the Transactions Date was recorded to partners’ capital.

Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). As noted above, the historical condensed consolidated financial statements of the Partnership reflect the historical condensed consolidated financial statements of the USA Compression Predecessor in accordance with the applicable accounting and financial reporting guidance. Therefore, the historical condensed consolidated financial statements are comprised of the USA Compression Predecessor for periods prior to the Transactions Date. The historical condensed consolidated financial statements are also comprised of the condensed consolidated balance sheet and statement of operations of the Partnership, which includes the USA Compression Predecessor, as of and for all periods subsequent to the Transactions Date.

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 GAAP. Operating results for the three and nine months ended September 30, 2019 are not necessarily indicative of the results that may be expected for the year ending December 31, 2019. 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 SEC. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements contained in our annual report on Form 10-K for the year ended December 31, 2018 filed on February 19, 2019 (our “2018 Annual Report”).

USA Compression Predecessor

ETO allocated various corporate overhead expenses to the USA Compression Predecessor based on a percentage of assets, net income (loss), or adjusted earnings before interest, taxes, depreciation and amortization (“EBITDA”). These

allocations are not necessarily indicative of the cost that the USA Compression Predecessor would have incurred had it operated as an independent standalone entity. The USA Compression Predecessor also historically relied upon ETO for funding operating and capital expenditures as necessary. As a result, the historical financial statements of the USA Compression Predecessor may not fully reflect or be indicative of what the USA Compression Predecessor’s balance sheet, results of operations and cash flows would have been or will be in the future.

Certain expenses incurred by ETO are only indirectly attributable to the USA Compression Predecessor. As a result, certain assumptions and estimates are made in order to allocate a reasonable share of such expenses to the USA Compression Predecessor, so that the accompanying financial statements reflect substantially all costs of doing business. The allocations and related estimates and assumptions are described more fully in Note 12.

Certain amounts of the USA Compression Predecessor’s revenues are derived from related party transactions, as described more fully in Note 12.

Significant Accounting Policies

Cash and Cash Equivalents

Cash and cash equivalents consist of all cash balances. We consider investments in highly liquid financial instruments purchased with an original maturity of 90 days or less to be cash equivalents.

Trade Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Our determination of the allowance for doubtful accounts requires us to make estimates and judgments regarding our customers’ ability to pay amounts due. We continuously evaluate 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.

The USA Compression Predecessor determined its allowance for doubtful accounts based upon historical write-off experience and specific identification of unrecoverable amounts.

Inventories

Inventories consist of serialized and non-serialized parts used primarily in the repair of compression units. All inventories are stated at the lower of cost or net realizable value. Serialized parts inventories are determined using the specific identification method, while non-serialized parts inventories are determined using the weighted average cost method. Purchases of inventories are considered operating activities on the unaudited condensed consolidated statements of cash flows.

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 three to five years. Ordinary maintenance and repairs are charged to cost of operations, exclusive of depreciation and amortization.

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.

Capitalized interest is calculated by multiplying the Partnership’s monthly effective interest rate on outstanding debt by the amount of qualifying costs, which include upfront payments to acquire certain compression units. Capitalized interest was $0.1 million and $0.5 million for the three and nine months ended September 30, 2019, respectively, and $0.2 million and $0.3 million for the three and nine months ended September 30, 2018, respectively.

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 evaluated for impairment is when idle units do not meet the desired performance characteristics of our active revenue generating horsepower.

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, based on an estimate of discounted cash flows, the expected net sale proceeds compared to the other similarly configured fleet units we recently sold or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment we plan to use.

Refer to Note 5 for more detailed information about impairment charges during the three and nine months ended September 30, 2019 and 2018.

Identifiable Intangible Assets

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 of our intangible assets range from 15 to 25 years.

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 during the three and nine months ended September 30, 2019 and 2018.

Goodwill

Goodwill represents consideration paid in excess of the fair value of the identifiable net assets acquired in a business combination. Goodwill is not amortized, but is reviewed for impairment annually based on the carrying values as of October 1, or more frequently if impairment indicators arise that suggest the carrying value of goodwill may not be recovered.

We did not record any impairment of goodwill during the three and nine months ended September 30, 2019 and 2018.

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. Incidental items, if any, that are immaterial in the context of the contract are recognized as expenses.

Pass Through Taxes

Sales taxes incurred on behalf of, and passed through to, customers are accounted for on a net basis.

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 non-recurring 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 September 30, 2019, 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 fair value of our Senior Notes 2026 and Senior Notes 2027, both defined in Note 8, were estimated using quoted prices in inactive markets and are considered Level 2 measurements.

The following table summarizes the aggregate principal amount and fair value of our Senior Notes 2026 and Senior Notes 2027 (in thousands):


	September 30, 2019		December 31, 2018
	Level 2		Level 2

Use of Estimates

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.

Operating Segment

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

Adoption of Lease Accounting Standard

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), which has amended the FASB Accounting Standards Codification (“ASC”) and introduced ASC Topic 842, Leases (“ASC Topic 842”). On January 1, 2019, we adopted ASC Topic 842, which is effective for interim and annual reporting periods beginning on or after December 15, 2018. ASC Topic 842 requires entities to recognize lease assets and liabilities on the balance sheet for all leases with a term of more than one year, including operating leases, which historically were not recorded on the balance sheet in accordance with the prior standard.

To adopt ASC Topic 842, we recognized a cumulative catch-up adjustment to the opening balance sheet presented January 1, 2019 related to certain leases that existed as of that date. As permitted, we have not retrospectively modified our consolidated financial statements for comparative purposes. The adoption of the standard had an impact on our consolidated balance sheet, but did not have an impact on our consolidated statements of operations or cash flows. As a result of adoption, we have recorded additional net right-of-use (“ROU”) lease assets and lease liabilities of approximately $3.5 million and $3.7 million, respectively, as of January 1, 2019. In addition, we have updated our business processes, systems and internal controls to support the on-going reporting requirements under the new standard.

To adopt ASC Topic 842, we elected the package of practical expedients permitted under the transition guidance within the standard. The expedient package allowed us not to reassess whether existing contracts contained a lease, the lease classification of existing leases and initial direct cost for existing leases. In addition to the package of practical expedients, we have elected not to capitalize amounts pertaining to leases with terms less than twelve months, to use the portfolio approach to determine discount rates, not to separate non-lease components from lease components and not to apply the use of hindsight to the active lease population.

Cumulative-effect adjustments made to the opening balance sheet at January 1, 2019 were as follows (in thousands):



		Balance at		Adjustments Due to
	Balance Sheet	December 31, 2018, as		ASC Topic 842		Balance at
Assets (liabilities)	Line Item	Previously Reported		(Leases)		January 1, 2019
Operating lease right-of-use assets	Other assets	$	—	$	3,502	$	3,502

The allowance for doubtful accounts, which was $1.8 million and $1.7 million at September 30, 2019 and December 31, 2018, respectively, is our best estimate of the amount of probable credit losses included in our existing accounts receivable.

During the nine months ended September 30, 2019, we recognized bad debt expense of $0.3 million and wrote-off $0.2 million of receivables on accounts previously reserved, resulting in a $0.1 million increase in our allowance for doubtful accounts.

During the three and nine months ended September 30, 2018, we increased our allowance for doubtful accounts by $0.5 million and $0.9 million, respectively, due primarily to estimated uncollectible amounts from customers of the USA Compression Predecessor.

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		5 - 25 years
Furniture and fixtures		3 - 10 years
Vehicles and computer equipment		1 - 10 years
Buildings		5 years
Leasehold improvements		5 years

Depreciation expense on property and equipment was $50.2 million and $151.2 million for the three and nine months ended September 30, 2019, respectively, and $51.5 million and $136.0 million for the three and nine months ended September 30, 2018, respectively.

As of September 30, 2019 and December 31, 2018, there was $11.7 million and $7.9 million, respectively, of property and equipment purchases in accounts payable and accrued liabilities.

During the three and nine months ended September 30, 2019, we recognized $2.0 million and $0.4 million of net gains on disposition of assets, respectively.

During the three and nine months ended September 30, 2018, we recognized $1.3 million and $12.3 million of net losses on disposition of assets, respectively. The net loss for the nine months ended September 30, 2018 was primarily attributable to disposals of various property and equipment by the USA Compression Predecessor.

On a quarterly basis, we evaluate the future deployment of our idle fleet under then-current market conditions. For the nine months ended September 30, 2019 and for the three and nine months ended September 30, 2018, we determined to retire or re-utilize key components of 14 compressor units and 18 compressor units, respectively, or approximately 4,700 horsepower and 5,800 horsepower, respectively, that were previously used to provide services in our business. As a result, we recorded $3.2 million in impairment of compression equipment for the nine months ended September 30, 2019 and $2.3 million for the three and nine months ended September 30, 2018.

The primary causes for these impairments were: (i) units were not considered marketable in the foreseeable future, (ii) units were subject to excessive maintenance costs or (iii) units were unlikely to be accepted by customers due to certain performance characteristics of the unit, such as the inability to meet then-current quoting criteria without excessive retrofitting costs. These compression units were written down to their respective estimated salvage values, if any.

No impairment was recorded for the three months ended September 30, 2019.

Lessee Accounting

We maintain both finance leases and operating leases, primarily related to office space, warehouse facilities and certain corporate equipment. Our leases have remaining lease terms of up to ten years, some of which include options that permit renewals for additional periods.

We determine if an arrangement is a lease at inception. Operating leases are included in other assets, accrued liabilities and other liabilities in our unaudited condensed consolidated balance sheets. Finance leases are included in property and equipment, accrued liabilities and other liabilities in our unaudited condensed consolidated balance sheets.

ROU lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU lease assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available on the commencement date in determining the present value of lease payments. ROU lease assets also include any lease payments made and exclude lease incentives. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable costs such as our proportionate share of actual costs for utilities, common area maintenance, property taxes and insurance are not included in the lease liability and are recognized in the period in which they are incurred.

For short-term leases (leases that have terms of twelve months or less upon commencement), lease payments are recognized on a straight line basis and no ROU assets are recorded. For certain equipment leases, such as office equipment, we account for the lease and non-lease components as a single lease component.

As of September 30, 2019, we have entered into additional operating leases that have not yet commenced with an estimated present value of $13.7 million. These operating leases will be commencing over the fourth quarter of 2019 through the first quarter of 2020 and each with terms of ten years.

Lessor Accounting

We granted a bargain purchase option to a customer with respect to certain compressor packages leased to the customer. The bargain purchase option provides the customer with an option to acquire the equipment at a value significantly less than the fair market value at the end of the lease term in 2021.

We accounted for this option as a sales type lease resulting in a current installment receivable included in other accounts receivable of $3.9 million and $3.7 million, and a long-term installment receivable of $4.0 million and $6.9 million as of September 30, 2019 and December 31, 2018, respectively.

Revenue and interest income related to the lease is recognized over the lease term. We recognize maintenance revenue within contract operations revenue and interest income within interest expense, net. Maintenance revenue was $0.4 million and $1.0 million for the three and nine months ended September 30, 2019, respectively, and $0.3 million and $0.6 million for the three and nine months ended September 30, 2018, respectively. Interest income was $0.1 million and $0.5 million for the three and nine months ended September 30, 2019, respectively, and $0.2 million and $0.5 million for the three and nine months ended September 30, 2018, respectively.

ASC Topic 842 provides lessors with a practical expedient to not separate non-lease components from the associated lease components and, instead, to account for those components as a single component if the non-lease components otherwise would be accounted for under ASC Topic 606 Revenue from Contracts with Customers (“ASC Topic 606”) and certain conditions are met. Our contract operations services agreements meet these conditions and we consider the predominant component to be the non-lease components, resulting in the ongoing recognition of revenue following ASC Topic 606 guidance.

Revolving Credit Facility

As of September 30, 2019, we were in compliance with all of our covenants under the Sixth Amended and Restated Credit Agreement (the “Credit Agreement”). The Credit Agreement has an aggregate commitment of $1.6 billion (subject to availability under our borrowing base), with a further potential increase of $400 million, and has a maturity date of April 2, 2023.

As of September 30, 2019, we had outstanding borrowings under the Credit Agreement of $394.5 million, $1.2 billion of borrowing base availability and, subject to compliance with the applicable financial covenants, available borrowing capacity of $410.4 million. Our interest rate in effect for all borrowings under the Credit Agreement as of September 30,

2019 was 4.73%, with a weighted average interest rate of 4.98% for the nine months ended September 30, 2019. There were no letters of credit issued as of September 30, 2019.

The Credit Agreement permits us to make distributions of available cash to unitholders so long as (a) no default under the facility has occurred, is continuing or would result from the distribution, (b) immediately prior to and after giving effect to such distribution, we are in compliance with the facility’s financial covenants and (c) immediately after giving effect to such distribution, we have availability under the Credit Agreement of at least $100 million.

The Credit Agreement also contains various financial covenants, including covenants requiring us to maintain:

●

a minimum EBITDA to interest coverage ratio of 2.5 to 1.0, determined as of the last day of each fiscal quarter; and

●

a maximum funded debt to EBITDA ratio, determined as of the last day of each fiscal quarter, for the annualized trailing three months of (a) 5.5 to 1.0 through the end of the fiscal quarter ending December 31, 2019 and (b) 5.00 to 1.0 thereafter, in each case subject to a provision for increases to such thresholds by 0.5 in connection with certain future acquisitions for the six consecutive month period following the period in which any such acquisition occurs.

The Credit Agreement matures in April 2023 and we expect to maintain it for the term. The Credit Agreement is a “revolving credit facility” that includes a lock box arrangement, whereby remittances from customers are forwarded to a bank account controlled by the administrative agent and are applied to reduce borrowings under the facility.

Senior Notes 2026

On March 23, 2018, the Partnership and its wholly owned finance subsidiary, USA Compression Finance Corp. (“Finance Corp”), co-issued $725.0 million aggregate principal amount of senior notes due on April 1, 2026 (the “Senior Notes 2026”). The Senior Notes 2026 accrue interest at the rate of 6.875% per year. Interest on the Senior Notes 2026 is payable semi-annually in arrears on each of April 1 and October 1.

The indenture governing the Senior Notes 2026 (the “2026 Indenture”) contains a Fixed Charge Coverage Ratio (as defined in the 2026 Indenture) that we must comply with in order to make certain Restricted Payments (as defined in the 2026 Indenture).

The Senior Notes 2026 are fully and unconditionally guaranteed (the “2026 Guarantees”), jointly and severally, on a senior unsecured basis by all of our existing subsidiaries (other than Finance Corp), and will be fully and unconditionally guaranteed, jointly and severally, by 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 2026 and the 2026 Guarantees are 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 the Guarantors’ and our future subordinated indebtedness, if any. The Senior Notes 2026 and the 2026 Guarantees are effectively subordinated in right of payment to all of the Guarantors’ and our existing and future secured debt, including debt under the Credit Agreement 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 Senior Notes 2026.

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. Each of the Guarantors is 100% owned by us. 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 (the “Securities Act”).

On January 14, 2019, the Partnership closed an exchange offer whereby holders of the Senior Notes 2026 exchanged all of the Senior Notes 2026 for an equivalent amount of senior notes (“2026 Exchange Notes”) registered under the Securities Act. The 2026 Exchange Notes are substantially identical to the Senior Notes 2026, except that the 2026 Exchange Notes have been registered with the SEC and do not contain the transfer restrictions, restrictive legends, registration rights or additional interest provisions of the Senior Notes 2026.

Senior Notes 2027

On March 7, 2019, the Partnership and Finance Corp co-issued $750.0 million aggregate principal amount of senior notes due on September 1, 2027 (the “Senior Notes 2027”). The Senior Notes 2027 accrue interest from March 7, 2019 at the rate of 6.875% per year. Interest on the Senior Notes 2027 is payable semi-annually in arrears on each of March 1 and September 1, with the first such payment having occurred on September 1, 2019.

At any time prior to September 1, 2022, we may redeem up to 35% of the aggregate principal amount of the Senior Notes 2027 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 Senior Notes 2027 remains outstanding immediately after the occurrence of such redemption (excluding Senior Notes 2027 held by us and our subsidiaries) and redemption occurs within 180 days of the date of the closing of such equity offering.

Prior to September 1, 2022, we may redeem all or a part of the Senior Notes 2027 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 September 1, 2022, we may redeem all or a part of the Senior Notes 2027 at redemption prices (expressed as percentages of the principal amount) set forth below, plus accrued and unpaid interest, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on September 1 of the years indicated below:


Year	Percentages
2022	105.156	%
2023	103.438	%
2024	101.719	%
2025 and thereafter	100.000	%

If we experience a change of control followed by a ratings decline, unless we have previously exercised or concurrently exercise our right to redeem the Senior Notes 2027 (as described above), we may be required to offer to repurchase the Senior Notes 2027 at a purchase price equal to 101% of the principal amount repurchased, plus accrued and unpaid interest, if any, to the repurchase date.

The indenture governing the Senior Notes 2027 (the “2027 Indenture”) contains a Fixed Charge Coverage Ratio (as defined in the 2027 Indenture) that we must comply with in order to make certain Restricted Payments (as defined in the 2027 Indenture).

In connection with issuing the Senior Notes 2027, we incurred certain issuance costs in the amount of $13.1 million, which is amortized over the term of the Senior Notes 2027.

The Senior Notes 2027 are fully and unconditionally guaranteed (the “2027 Guarantees”), jointly and severally, on a senior unsecured basis by the Guarantors. The Senior Notes 2027 and the 2027 Guarantees are general unsecured obligations and rank equally in right of payment with all of the Guarantors’ and our existing and future senior indebtedness, including the Exchange Notes, and senior to the Guarantors’ and our future subordinated indebtedness, if any. The Senior Notes 2027 and the 2027 Guarantees are effectively subordinated in right of payment to all of the Guarantors’ and our existing and future secured debt, including debt under the Credit Agreement 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 Senior Notes 2027.

Preferred Units and Warrants

(9) Preferred Units and Warrants

On the Transactions Date, we completed a private placement of $500 million in the aggregate of (i) newly authorized and established Series A Preferred Units (the “Preferred Units”) and (ii) warrants to purchase common units (the “Warrants”) pursuant to a Series A Preferred Unit and Warrant Purchase Agreement dated January 15, 2018, with certain investment funds managed or advised by EIG Global Energy Partners (collectively, the “Preferred Unitholders”). We issued 500,000 Preferred Units with a face value of $1,000 per Preferred Unit and issued two tranches of Warrants to the Preferred Unitholders, which included Warrants to purchase 5,000,000 common units with a strike price of $17.03 per unit and 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 April 2, 2019 and before April 2, 2028.

The Preferred Units rank senior to the common units with respect to distributions and rights upon liquidation. The Preferred Unitholders are entitled to receive cumulative quarterly cash distributions equal to $24.375 per Preferred Unit. The distribution attributable to the quarter ended September 30, 2019 will be paid on November 8, 2019 to Preferred Unitholders of record as of the close of business on October 28, 2019.

The Preferred Units are presented as temporary equity in the mezzanine section of the unaudited condensed consolidated balance sheets because the redemption provisions exercisable on or after April 2, 2028 are outside the Partnership’s control. The Preferred Units have been recorded at their issuance date fair value, net of issuance cost. Net income allocations increase the carrying value and declared distributions decrease the carrying value of the Preferred Units. As the Preferred Units are not currently redeemable and it is not probable that they will become redeemable by us, adjustment to the initial carrying amount is not necessary and would only be required if it becomes probable that the Preferred Units would become redeemable by us.

Changes in the Preferred Units balance from December 31, 2018 through September 30, 2019 are summarized below (in thousands):


	Preferred Units
Balance at December 31, 2018	$	477,309
Net income allocated to Preferred Units		36,563
Cash distributions on Preferred Units		(36,563)
Balance at September 30, 2019	$	477,309

The Warrants are presented within the equity section of the unaudited condensed consolidated balance sheets in accordance with GAAP as they are indexed to the Partnership’s common units and require physical settlement or net common unit settlement.

Refer to Note 12 for information about the rights EIG Veteran Equity Aggregator, L.P. (along with its affiliated funds, “EIG”) has to designate one of the members of the Board of Directors of USA Compression GP, LLC (the “Board”).

Common Units

As of September 30, 2019, we had 96,615,998 common units outstanding. As of September 30, 2019, ETO held 46,056,228 common units, including 8,000,000 common units held by the General Partner and controlled by ETO.

Class B Unit Conversion

On July 30, 2019, 6,397,965 Class B Units automatically converted into common units on a one-for-one basis, resulting in the issuance of 6,397,965 common units to ETO. Following the conversion, there are no longer Class B Units outstanding.

Cash Distributions

As the USA Compression Predecessor is deemed to be the predecessor of the Partnership for financial reporting purposes, cash distributions paid by the Partnership related to periods prior to the Transactions Date are not included

within the results of operations presented within the unaudited condensed consolidated financial statements for the nine months ended September 30, 2018.

We have declared quarterly distributions per unit to our limited partner unitholders of record, including holders of our common units and phantom units, as follows (dollars in millions, except distribution per unit):


	Distribution per		Amount Paid to		Amount Paid to
	Limited Partner		Common		Phantom		Total
Payment Date	Unit		Unitholders		Unitholders		Distribution
August 10, 2018	$	0.525	$	47.2	$	0.4	$	47.6

August 9, 2019	$	0.525	$	47.4	$	0.6	$	48.0

Announced Quarterly Distribution

On October 17, 2019, we announced a cash distribution of $0.525 per unit on our common units. The distribution will be paid on November 8, 2019 to common unitholders of record as of the close of business on October 28, 2019.

Distribution Reinvestment Plan

During the nine months ended September 30, 2019, distributions of $0.7 million were reinvested under the Distribution Reinvestment Plan (“DRIP”) resulting in the issuance of 44,605 common units.

Earnings Per Unit

The computation of earnings per unit is based on the weighted average number of participating securities outstanding during the applicable period. Basic earnings per unit is determined by dividing net income (loss) allocated to participating securities after deducting the amount distributed on Preferred Units, by the weighted average number of participating securities outstanding during the period. Net income (loss) is allocated to participating securities 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 securities 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 and Warrants. The classes of participating securities include common units, Class B Units prior to July 30, 2019, and certain equity-based compensation awards. Unvested phantom units and unexercised Warrants 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 to the extent that they are dilutive, and in the case of Warrants to the extent they are considered “in the money.” For the three and nine months ended September 30, 2019, approximately 221,000 and 169,000 incremental unvested phantom units, respectively, represent the differences between our basic and diluted weighted average common units outstanding. For the three and nine months ended September 30, 2019, our outstanding Warrants are not included in the computation as they are not considered “in the money” for each period. For the three and nine months ended September 30, 2018, approximately 156,000 and 52,000 incremental unvested phantom units, respectively, and zero and 31,000 incremental warrants, respectively, were excluded from the calculation of diluted earnings per common unit because the impact was anti-dilutive.

On January 1, 2018, we adopted ASC Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018.

We identified no material impact on our historical revenues upon initial application of ASC Topic 606, and as such did not recognize 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 had no material impact on any financial statement line items.

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 September 30, 2019 and December 31, 2018. There were no significant changes to our trade accounts receivable balances due to contract modifications or 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 nine months ended September 30, 2019 is primarily driven by cash payments received or due in advance of satisfying our performance obligations under a contract. 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.

(12) Transactions with Related Parties

We provide compression services to entities affiliated with ETO, which as of September 30, 2019 owned approximately 48% of our limited partner interests and 100% of the General Partner. During the three and nine months ended September 30, 2019, we recognized revenue of $5.1 million and $15.5 million, respectively, from such affiliated entities and we recognized revenue of $4.3 million and $12.8 million during the three and nine months ended September 30, 2018, respectively.

We had $3.7 million and $2.7 million in receivables and $2 thousand and $0.4 million in payables as of September 30, 2019 and December 31, 2018, respectively, from such affiliated entities. Additionally, the Partnership had a $44.9 million related party receivable from ETO as of September 30, 2019 and December 31, 2018, related to indemnification for sales tax contingencies incurred by the USA Compression Predecessor. See Note 13 for more information related to such sales tax contingencies.

ETO provided certain benefits to the USA Compression Predecessor employees which did not continue following the Transactions Date. ETO provided medical, dental and other healthcare benefits to the USA Compression Predecessor employees. The total amount incurred by ETO for the benefit of the USA Compression Predecessor employees for the nine months ended September 30, 2018 was $1.9 million, which was allocated to the USA Compression Predecessor and recorded in operation and maintenance and general and administrative expenses, as appropriate. ETO also provided a

matching contribution to the USA Compression Predecessor employees’ 401(k) accounts. The total amount of matching contributions incurred for the benefit of the USA Compression Predecessor employees for the nine months ended September 30, 2018 was $0.9 million, which was allocated to the USA Compression Predecessor and recorded in operation and maintenance and general and administrative expenses, as appropriate. ETO also provided a 3% profit sharing contribution to the 401(k) accounts for all USA Compression Predecessor employees with base compensation below a specified threshold. The contribution was in addition to the 401(k) matching contribution and employees became vested in the profit sharing contribution based on years of service.

ETO allocated certain overhead costs associated with general and administrative services, including salaries and benefits, facilities, insurance, information services, human resources and other support departments to the USA Compression Predecessor which did not continue following the Transactions Date. Where costs incurred on the USA Compression Predecessor’s behalf could not be determined by specific identification, the costs were primarily allocated to the USA Compression Predecessor based on an average percentage of fixed assets, net income (loss) and adjusted EBITDA. The USA Compression Predecessor believes these allocations were a reasonable reflection of the utilization of services provided. However, the allocations may not fully reflect the expenses that would have been incurred had the USA Compression Predecessor been a standalone company during the periods presented. During the nine months ended September 30, 2018, ETO allocated general and administrative expenses of $1.8 million to the USA Compression Predecessor.

Pursuant to that certain Board Representation Agreement entered into by us, the General Partner, ET LP and EIG in connection with our private placement of Preferred Units and Warrants to EIG, EIG Management Company, LLC has the right to designate one of the members of the Board for so long as the holders of the Preferred Units hold more than 5% of the Partnership’s outstanding common units in the aggregate (taking into account the common units that would be issuable upon conversion of the Preferred Units and exercise of the Warrants).

(a) Major Customers

We did not have revenue from any single customer representing 10% or more of total revenue for the three and nine months ended September 30, 2019 or 2018.

(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.

Our future capital commitments are comprised of binding commitments under purchase orders for new compression units and serialized parts ordered but not received. Those commitments as of September 30, 2019 were $47.7 million, $7.8 million of which we expect to settle in the remainder of 2019.

(d) Sales Tax Contingency

Our compliance with state and local sales tax regulations is subject to audit by various taxing authorities. The Office of the Texas Comptroller of Public Accounts (“Comptroller”) has 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 companies in our industry have disputed these claims based on existing tax statutes which provide for manufacturing exemptions on the transactions in question. The manufacturing exemptions are based on the fact that our natural gas compression equipment is used in the process of preparing natural gas for ultimate use and sale.

The USA Compression Predecessor has several open audits with the Comptroller for certain periods prior to the Transactions Date wherein the Comptroller has challenged the applicability of the manufacturing exemption. Any liability for the periods prior to the Transactions Date is covered by an indemnity between us and ETO. As of September 30, 2019, we have recorded a $44.9 million accrued liability and $44.9 million related party receivable from ETO.

For more information, see Note 17 to the consolidated financial statements included in our 2018 Annual Report.

(e) Self-Insurance

Effective January 1, 2019, we became self-insured for medical claims up to certain stop loss limits. Liabilities are accrued for self-insured claims when sufficient information is available to reasonably estimate the amount of the loss. As of September 30, 2019, we have recorded a $0.8 million accrued liability.

The amendments to ASC Topic 326 require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. The amendments in this update are effective for interim and annual periods beginning after January 1, 2020, with early adoption permitted by one year. We plan to adopt this new standard on January 1, 2020 and expect that our adoption of this standard will not have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (“ASC Topic 820”): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. The amendments to ASC Topic 820 eliminate, add and modify certain disclosure requirements for fair value measurements as part of the FASB’s disclosure framework project. The amendments in this update are effective for interim and annual periods beginning on January 1, 2020, with early adoption permitted. We plan to adopt this new standard on January 1, 2020. We expect the impact to our disclosures will not be material and there to be no impact to our consolidated financial statements.

Basis of Presentation and Summary of Significant Accounting Policies
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of all cash balances. We consider investments in highly liquid financial instruments purchased with an original maturity of 90 days or less to be cash equivalents.
Trade Accounts Receivable and Allowance for Doubtful Accounts	Trade Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Our determination of the allowance for doubtful accounts requires us to make estimates and judgments regarding our customers’ ability to pay amounts due. We continuously evaluate 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. The USA Compression Predecessor determined its allowance for doubtful accounts based upon historical write-off experience and specific identification of unrecoverable amounts.
Inventories	Inventories Inventories consist of serialized and non-serialized parts used primarily in the repair of compression units. All inventories are stated at the lower of cost or net realizable value. Serialized parts inventories are determined using the specific identification method, while non-serialized parts inventories are determined using the weighted average cost method. Purchases of inventories are considered operating activities on the unaudited condensed consolidated statements of cash flows.
Property and Equipment	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 three to five years. Ordinary maintenance and repairs are charged to cost of operations, exclusive of depreciation and amortization. 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. Capitalized interest is calculated by multiplying the Partnership’s monthly effective interest rate on outstanding debt by the amount of qualifying costs, which include upfront payments to acquire certain compression units. Capitalized interest was $0.1 million and $0.5 million for the three and nine months ended September 30, 2019, respectively, and $0.2 million and $0.3 million for the three and nine months ended September 30, 2018, respectively.
Impairments of Long-Lived Assets	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 evaluated for impairment is when idle units do not meet the desired performance characteristics of our active revenue generating horsepower. 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, based on an estimate of discounted cash flows, the expected net sale proceeds compared to the other similarly configured fleet units we recently sold or a review of other units recently offered for sale by third parties, or the estimated component value of the equipment we plan to use. Refer to Note 5 for more detailed information about impairment charges during the three and nine months ended September 30, 2019 and 2018.
Identifiable Intangible Assets	Identifiable Intangible Assets 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 of our intangible assets range from 15 to 25 years. 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 during the three and nine months ended September 30, 2019 and 2018.
Goodwill	Goodwill Goodwill represents consideration paid in excess of the fair value of the identifiable net assets acquired in a business combination. Goodwill is not amortized, but is reviewed for impairment annually based on the carrying values as of October 1, or more frequently if impairment indicators arise that suggest the carrying value of goodwill may not be recovered. We did not record any impairment of goodwill during the three and nine months ended September 30, 2019 and 2018.
Revenue Recognition	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. Incidental items, if any, that are immaterial in the context of the contract are recognized as expenses.
Pass Through Taxes	Pass Through Taxes Sales taxes incurred on behalf of, and passed through to, customers are accounted for on a net basis.
Fair Value Measurements	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 non-recurring 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 September 30, 2019, 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 fair value of our Senior Notes 2026 and Senior Notes 2027, both defined in Note 8, were estimated using quoted prices in inactive markets and are considered Level 2 measurements.
Use of Estimates	Use of Estimates 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.
Operating Segment	Operating Segment We operate in a single business segment, the compression services business.
Adoption of Lease Accounting Standard	Adoption of Lease Accounting Standard In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842), which has amended the FASB Accounting Standards Codification (“ASC”) and introduced ASC Topic 842, Leases (“ASC Topic 842”). On January 1, 2019, we adopted ASC Topic 842, which is effective for interim and annual reporting periods beginning on or after December 15, 2018. ASC Topic 842 requires entities to recognize lease assets and liabilities on the balance sheet for all leases with a term of more than one year, including operating leases, which historically were not recorded on the balance sheet in accordance with the prior standard. To adopt ASC Topic 842, we recognized a cumulative catch-up adjustment to the opening balance sheet presented January 1, 2019 related to certain leases that existed as of that date. As permitted, we have not retrospectively modified our consolidated financial statements for comparative purposes. The adoption of the standard had an impact on our consolidated balance sheet, but did not have an impact on our consolidated statements of operations or cash flows. As a result of adoption, we have recorded additional net right-of-use (“ROU”) lease assets and lease liabilities of approximately $3.5 million and $3.7 million, respectively, as of January 1, 2019. In addition, we have updated our business processes, systems and internal controls to support the on-going reporting requirements under the new standard. To adopt ASC Topic 842, we elected the package of practical expedients permitted under the transition guidance within the standard. The expedient package allowed us not to reassess whether existing contracts contained a lease, the lease classification of existing leases and initial direct cost for existing leases. In addition to the package of practical expedients, we have elected not to capitalize amounts pertaining to leases with terms less than twelve months, to use the portfolio approach to determine discount rates, not to separate non-lease components from lease components and not to apply the use of hindsight to the active lease population.
