The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements presented in our 2019 Form 10-K, which contains a more comprehensive summary of our accounting policies. The interim results reported herein are not necessarily indicative of results for a full year. Certain prior year amounts have been reclassified to conform to the current year presentation.

2. Recent Accounting Developments

Accounting Standards Updates Implemented

Credit Losses

In June 2016, the FASB issued ASU 2016-13, which changes the impairment model for financial assets measured at amortized cost and certain other instruments, and requires entities to use a new current expected credit loss model that results in recognition of expected losses over the contractual life of an asset. We adopted ASU 2016-13 on January 1, 2020 using the modified retrospective approach. The adoption resulted in a $0.2 million decrease in our allowance for credit losses and a corresponding pre-tax cumulative effect adjustment to retained earnings in our condensed consolidated balance sheet at January 1, 2020. Comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

Our financial assets measured at amortized cost consist of cash equivalents and trade receivables from revenue transactions within the scope of ASC 606 Revenue. We believe our temporary cash investments have a zero loss expectation because we maintain minimal balances in our cash investment accounts and have no history of loss. Trade accounts receivable are due from companies of varying size engaged principally in oil and natural gas activities throughout the U.S. We review the financial condition of customers prior to extending credit and generally do not obtain collateral for trade receivables. Payment terms are on a short-term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ financial resources, the nature of the products and services we provide and the terms of our customer agreements.

11

Due to the short-term nature of our trade receivables, we consider the amortized cost to be the same as the carrying amount of the receivable, excluding the allowance for credit losses. We recognize an allowance for credit losses when a receivable is recorded, even when the risk of loss is remote. We utilize an aging schedule to determine our allowance for credit losses, and measure expected credit losses on a collective (pool) basis when similar risk characteristics exist. We rely primarily on ratings assigned by external rating agencies and credit monitoring services to assess credit risk and aggregate customers first by low, medium or high risk asset pools, and then by delinquency status. We also consider the internal risk associated with geographic location and the services we provide to the customer when determining asset pools. If a customer does not share similar risk characteristics with other customers, we evaluate the customer’s outstanding trade receivables for expected credit losses on an individual basis. Trade receivables evaluated individually are not included in our collective assessment. Each reporting period, we reassess our customers’ risk profiles and determine the appropriate asset pool classification, or perform individual assessments of expected credit losses, based on the customers’ risk characteristics at the reporting date.

The contractual life of our trade receivables is primarily 30 days based on the payment terms specified in the contract. Contract operations services are generally billed monthly at the beginning of the month in which service is being provided. Aftermarket services billings typically occur when parts are delivered or service is completed. Loss rates are separately determined for each asset pool based on the length of time a trade receivable has been outstanding. We analyze two years of internal historical loss data, including the effects of prepayments, write-offs and subsequent recoveries, to determine our historical loss experience. Our historical loss information is a relevant data point for estimating credit losses, as the data closely aligns with trade receivables due from our customers. Ratings assigned by external rating agencies and credit monitoring services consider past performance and forecasts of future economic conditions in assessing credit risk. We routinely update our historical loss data to reflect our customers’ current risk profile, to ensure the historical data and loss rates are relevant to the pool of assets for which we are estimating expected credit losses. Judgement is used to determine the expected credit loss for customers that do not share similar risk characteristics with other customers, based on customer specific items such as legal proceedings, past experience with the customer and/or ongoing customer negotiations.

The following table summarizes the changes in our allowance for credit losses balance during the six months ended June 30, 2020 (in thousands):

Balance at December 31, 2019	$	2,210
Impact of adoption of ASU 2016-13 on January 1, 2020		(216)
Provision for credit losses		2,282
Write-offs charged against allowance		(646)
Balance at June 30, 2020	$	3,630

Fair Value Measurements

On January 1, 2020, we adopted ASU 2018-13, which amends the required fair value measurements disclosures related to valuation techniques and inputs used, uncertainty in measurement and changes in measurements applied. These amendments resulted in new, prospective disclosures of the range and weighted average of the significant unobservable inputs used to develop our Level 3 fair value measurements related to our idle and previously-culled compressors. The adoption of ASU 2018-13 had no impact on our condensed consolidated financial statements.

Income Taxes

On January 1, 2020, we adopted ASU 2019-12, which simplifies the accounting for income taxes by, among other things, removing certain exceptions related to the incremental approach for intraperiod tax allocation, the year-to-date loss methodology for calculating income taxes in an interim period and the recognition for deferred tax liabilities on outside basis differences. ASU 2019-12 also clarifies other aspects of the accounting for income taxes in order to improve consistency of application. The adoption of ASU 2019-12 had no impact on our condensed consolidated financial statements.

Accounting Standards Updates Not Yet Implemented

Reference Rate Reform

In March 2020, the FASB issued ASU 2020-04, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued as a result of reference rate reform. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. Entities may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. We are currently assessing the impact that ASU 2020-04 may have on our interest rate swap agreements, Credit Facility and other transactions that may be affected by reference rate reform.

3. Business Transactions

March 2020 Disposition

On March 1, 2020, we completed the sale of certain contract operations customer service agreements and approximately 200 compressors, comprising approximately 35,000 horsepower, used to provide compression services under those agreements as well as other assets used to support the operations. We allocated customer and contract-related intangible assets and goodwill based on a ratio of the horsepower sold relative to the total horsepower of the asset group. We recognized a gain on the sale of $3.2 million in gain (loss) on sale of assets, net in our condensed consolidated statements of operations during the six months ended June 30, 2020.

Elite Acquisition

On August 1, 2019, we completed the Elite Acquisition whereby we acquired from Elite Compression substantially all of its assets, including a fleet of predominantly large compressors comprising approximately 430,000 horsepower, vehicles, real property and inventory, and certain liabilities for aggregate consideration consisting of $214.0 million in cash and 21.7 million shares of common stock with an acquisition date fair value of $225.9 million. The cash portion of the acquisition was funded with borrowings on the Credit Facility.

The Elite Acquisition was accounted for using the acquisition method, which requires, among other things, assets acquired and liabilities assumed to be recorded at their fair value on the acquisition date. The excess of the consideration transferred over those fair values is recorded as goodwill. The following table summarizes the purchase price allocation based on the estimated fair values of the acquired assets and liabilities as of the acquisition date (in thousands):

Accounts receivable	$	9,007
Inventory		7,987
Other current assets		608
Property, plant and equipment		286,158
Operating lease ROU assets		682
Goodwill		100,598
Intangible assets		40,237
Accounts payable, trade		(2,079)
Accrued liabilities		(2,973)
Operating lease liabilities		(326)
Purchase price	$	439,899

Our valuation methodology and significant inputs for fair value measurements are detailed by asset class below. The fair value measurements for property, plant and equipment and intangible assets are based on significant inputs that are not observable in the market and therefore represent Level 3 measurements.

13

Goodwill

The goodwill resulting from the acquisition is attributable to the expansion of our services in various regions in which we currently operate and was allocated to our contract operations segment. All of the goodwill recorded for this acquisition is expected to be deductible for U.S. federal income tax purposes.

Property, Plant and Equipment

The property, plant and equipment is primarily comprised of compression equipment that will be depreciated on a straight-line basis over an estimated average remaining useful life of 15 years. The fair value of the property, plant and equipment was determined using the cost approach, whereby we estimated the replacement cost of the assets by evaluating recent purchases of similar assets or published data, and then adjusted replacement cost for physical deterioration and functional and economic obsolescence, as applicable.

Intangible Assets

The intangible assets consist of customer relationships that have an estimated useful life of 15 years. The amount of intangible assets and their associated useful life were determined based on the period over which the assets are expected to contribute directly or indirectly to our future cash flows. The fair value of the identifiable intangible assets was determined using the multi-period excess earnings method, which is a specific application of the discounted cash flow method, an income approach, whereby we estimated and then discounted the future cash flows of the intangible asset by adjusting overall business revenue for attrition, obsolescence, cost of sales, operating expenses, taxes and the required returns attributable to other contributory assets acquired. Significant estimates made in arriving at expected future cash flows included our expected customer attrition rate and the amount of earnings attributable to the assets. To discount the estimated future cash flows, we utilized a discount rate that was at a premium to our weighted average cost of capital to reflect the less liquid nature of the customer relationships relative to the tangible assets acquired.

Unaudited Pro Forma Financial Information

Unaudited pro forma financial information for the three and six months ended June 30, 2019 was derived by adjusting our historical financial statements in order to give effect to the assets and liabilities acquired in the Elite Acquisition. The Elite Acquisition is presented in this unaudited pro forma financial information as though the acquisition occurred as of January 1, 2019, and reflects the following:

● the acquisition of substantially all of Elite Compression’s assets, including a compression fleet of approximately 430,000 horsepower, vehicles, real property and inventory, and certain liabilities; and

● borrowings of $214.0 million under the Credit Facility for cash consideration exchanged in the acquisition; and

● the exclusion of $2.5 million of financial advisory, legal and other professional fees incurred related to the acquisition and recorded to transaction-related costs in our condensed consolidated statements of operations during each of the three and six months ended June 30, 2019.

The unaudited pro forma financial information below is presented (in thousands) for informational purposes only and is not necessarily indicative of our results of operations that would have occurred had the transaction been consummated at the beginning of the period presented, nor is it necessarily indicative of future results.

	Three Months Ended		Six Months Ended
	June 30, 2019		June 30, 2019
Revenue	$	257,706	$	512,271
Net income		15,250		36,220

The results of operations attributable to the assets and liabilities acquired in the Elite Acquisition have been included in our condensed consolidated financial statements as part of our contract operations segment since the date of acquisition.

4. Discontinued Operations

In 2015 we completed the Spin-off. In order to effect the Spin-off and govern our relationship with Exterran Corporation after the Spin-off, we entered into several agreements with Exterran Corporation which include, but are not limited to, the separation and distribution agreement and the tax matters agreement.

The separation and distribution agreement specifies our right to promptly receive payments from Exterran Corporation based on a notional amount corresponding to payments received by Exterran Corporation from PDVSA in respect of the sale of Exterran Corporation’s previously-nationalized assets after such amounts are collected by Exterran Corporation. During the three months ended June 30, 2020, we received $0.7 million from Exterran Corporation pursuant to this term of the separation and distribution agreement. We also entered into an assignment from Exterran Corporation so that any future payments by PDVSA would be received directly by us.

The tax matters agreement governs the respective rights, responsibilities and obligations of Exterran Corporation and us with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and certain other matters regarding taxes. Subject to the provisions of this agreement, we and Exterran Corporation agreed to indemnify the primary obligor of any return for tax periods beginning before and ending before or after the Spin-off (including any ongoing or future amendments and audits for these returns) for the portion of the tax liability (including interest and penalties) that relates to their respective operations reported in the filing.

As of both June 30, 2020 and December 31, 2019, we had $8.5 million of unrecognized tax benefits (including interest and penalties) related to Exterran Corporation operations prior to the Spin-off recorded to noncurrent liabilities associated with discontinued operations in our condensed consolidated balance sheets. We had an offsetting indemnification asset of $8.5 million related to these unrecognized tax benefits recorded to noncurrent assets associated with discontinued operations as of both June 30, 2020 and December 31, 2019.

The following table presents the balance sheet for our discontinued operations (in thousands):

7. Goodwill

Our goodwill was recognized in connection with the Elite Acquisition and represents the excess of consideration transferred over the fair value of the assets and liabilities acquired. All of the goodwill was allocated to our contract operations reporting unit. We review the carrying amount of our goodwill in the fourth quarter of every year, or whenever indicators of potential impairment exist, to determine if the carrying amount of our contract operations reporting unit exceeds its fair value, including the goodwill. Beginning in the first quarter of 2020, the COVID-19 pandemic caused a significant deterioration in global macroeconomic conditions, including a collapse in the demand for oil coupled with an oversupply of oil, which commenced substantial spending cuts by our customers and a decline in production. This global response to the pandemic significantly impacted our market capitalization and estimates of future revenues and cash flows, which triggered the need to perform a quantitative test of the fair value of our contract operations reporting unit as of March 31, 2020. The quantitative test determined that the carrying amount of our contract operations reporting unit exceeded its fair value and we recorded a full impairment loss on goodwill in the first quarter as a result.

Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions, which have a significant impact on the fair value determined. We determine the fair value of our reporting unit using an equal weighting of both the expected present value of future cash flows and a market approach. The present value of future cash flows is estimated using our most recent forecast and the weighted average cost of capital. The market approach uses a market multiple on the earnings before interest expense, provision for income taxes and depreciation and amortization expense of comparable peer companies. Significant estimates for our reporting unit included in our impairment analysis are our cash flow forecasts, our estimate of the market’s weighted average cost of capital and market multiples.

Balance at December 31, 2019	$	100,598
Dispositions		(768)
Impairment loss		(99,830)
Balance at June 30, 2020	$	—

8. Hosting Arrangements

In the fourth quarter of 2018 we began a process and technology transformation project that will, among other things, upgrade or replace our existing ERP, supply chain and inventory management systems and expand the remote monitoring capabilities of our compression fleet. Included in this project are hosting arrangements that are service contracts related to the cloud migration of our ERP system and cloud services for our new mobile workforce, telematics and inventory management tools.

Certain costs incurred for the implementation of our hosting arrangements that are service contracts are capitalized and amortized on a straight-line basis over the term of the respective contract. Amortization begins in the period in which an individual component becomes ready for its intended use. As of June 30, 2020 and December 31, 2019, we capitalized $7.7 million and $5.5 million, respectively, of implementation costs related to our hosting arrangements that are service contracts to other assets in our condensed consolidated balance sheets. Accumulated amortization was $0.1 million at June 30, 2020. We recorded $0.1 million of amortization expense to SG&A in our condensed consolidated statements of operations during each of the three and six months ended June 30, 2020.

9. Long-Term Debt

Long-term debt consisted of the following (in thousands):

	June 30, 2020		December 31, 2019

Credit Facility

As of June 30, 2020, there were $12.4 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.5%. The weighted average annual interest rate on the outstanding balance under the Credit Facility, excluding the effect of interest rate swaps, was 2.7% and 4.3% at June 30, 2020 and December 31, 2019, respectively. We incurred $0.4 million and $0.6 million in commitment fees on the daily unused amount of the Credit Facility during the three months ended June 30, 2020 and 2019, respectively, and $1.1 million during each of the six months ended June 30, 2020 and 2019.

We must maintain certain consolidated financial ratios as defined in our Credit Facility agreement. As of June 30, 2020, the ratio requirements did not constrain our undrawn capacity and as such, $414.6 million was available for additional borrowings. As of June 30, 2020, we were in compliance with all covenants under the Credit Facility agreement.

2022 Notes Redemption

On April 1, 2020, the 2022 Notes were redeemed at 100% of their $350.0 million aggregate principal amount plus accrued and unpaid interest of $10.5 million with borrowings from the Credit Facility. A debt extinguishment loss of $4.0 million related to the redemption was recognized during the three and six months ended June 30, 2020.

10. Accumulated Other Comprehensive Income (Loss)

Components of comprehensive income (loss) are net income (loss) and all changes in equity during a period except those resulting from transactions with owners. Our accumulated other comprehensive income (loss) consists of changes in the fair value of our interest rate swap derivative instruments, net of tax, which are designated as cash flow hedges.

The following table presents the changes in accumulated other comprehensive income (loss) of our derivative cash flow hedges, net of tax, during the three and six months ended June 30, 2020 and 2019 (in thousands):

	Three Months Ended				Six Months Ended

(2) Primarily relates to fees associated with owned non-compression equipment.

(3) Includes $1.5 million and $2.2 million for the three months ended June 30, 2020 and 2019, respectively, and $3.1 million and $4.4 million for the six months ended June 30, 2020 and 2019, respectively, related to billable maintenance on owned compressors that was recognized at a point in time. All other contract operations revenue is recognized over time.

(4) All service revenue within aftermarket services is recognized over time. All OTC parts and components sales revenue is recognized at a point in time.

Performance Obligations

As of June 30, 2020, we had $416.8 million of remaining performance obligations related to our contract operations segment. We do not consider the effects of the time value of money, as the expected time between the transfer of services and payment for such services is less than one year. Our remaining performance obligations will be recognized through 2025 as follows (in thousands):

	2020		2021		2022		2023		2024		2025		Total
Remaining performance obligations	$	172,639	$	170,084	$	65,438	$	7,532	$	1,030	$	79	$	416,802

We do not disclose the aggregate transaction price for the remaining performance obligations for aftermarket services as there are no contracts with customers with an original contract term that is greater than one year.

Contract Assets and Liabilities

As of June 30, 2020 and December 31, 2019, our receivables from contracts with customers, net of allowance for credit losses, were $118.8 million and $139.4 million, respectively.

Freight billings to customers for the transport of compression assets, customer-specified modifications of compression assets and milestone billings on aftermarket services often result in a contract liability. As of June 30, 2020 and December 31, 2019, our contract liabilities were $6.9 million and $11.4 million, respectively, which were included in deferred revenue and other liabilities in our condensed consolidated balance sheets. The decrease in the contract liability balance during the six months ended June 30, 2020 was primarily due to $12.8 million recognized as revenue during the period, partially offset by revenue deferral of $8.3 million, each primarily related to freight billings and milestone billings on aftermarket services.

13. Long-Lived Asset Impairment

We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, for impairment whenever events or changes in circumstances, including the removal of compressors from our active fleet, indicate that the carrying amount of an asset may not be recoverable.

We periodically review the future deployment of our idle compression assets for units that are not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. Based on these reviews, we determine that certain idle compressors should be retired from the active fleet. The retirement of these units from the active fleet triggers a review of these assets for impairment and as a result of our review, we may record an asset impairment to reduce the book value of each unit to its estimated fair value. The fair value of each unit is estimated based on the expected net sale proceeds compared to other fleet units we recently sold, a review of other units recently offered for sale by third parties or the estimated component value of the equipment we plan to use.

In connection with our review of our idle compression assets, we evaluate for impairment idle units that were culled from our fleet in prior years and are available for sale. Based on that review, we may reduce the expected proceeds from disposition and record additional impairment to reduce the book value of each unit to its estimated fair value.

In the first quarter of 2020, we determined that the impairment of our contract operations reporting unit’s goodwill was an indicator of potential impairment of the carrying amount of our long-lived assets, including our compressor fleet and associated customer and contract-based intangible assets. Accordingly, we performed a quantitative impairment test of our long-lived assets, by which we determined that they were not also impaired. No similar impairment has been indicated subsequent to the first quarter.

14. Restructuring Charges

During the first quarter of 2020, we completed a series of restructuring activities to further streamline our organization and more fully align our teams to improve our customer service and profitability. We began additional restructuring activities in the second quarter in response to the decreased activity level of our customers that resulted from the COVID-19 pandemic. We incurred severance costs of $2.4 million and $4.1 million during the three and six months ended June 30, 2020, respectively, which are reflected as restructuring charges in our condensed consolidated statements of operations.

The following table presents the changes to our accrued liability balance related to restructuring charges during the six months ended June 30, 2020 (in thousands):

Balance at December 31, 2019	$	—
Severance costs		3,974
Non-cash expense		162
Payments		(2,885)
Balance at June 30, 2020	$	1,251

The following table presents, by segment, the restructuring charges incurred during the three and six months ended June 30, 2020 (in thousands):

	Contract		Aftermarket
	Operations		Services		Other (1)		Total
Three months ended June 30, 2020	$	1,386	$	286	$	736	$	2,408
Six months ended June 30, 2020		1,864		911		1,361		4,136

(1) Represents expense incurred within our corporate function and not directly attributable to our segments.

We are not currently able to estimate the amount of total costs to be incurred related to the restructuring activities commenced as a result of the COVID-19 pandemic, as the magnitude and duration of the pandemic and its impact on our operations remain difficult to predict.

15. Income Taxes

CARES Act

On March 27, 2020, President Trump signed into law the CARES Act, which includes, among other things, refundable payroll tax credits, deferment of employer side social security payments, NOL carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act provisions did not have a material impact on our condensed consolidated financial statements. Future regulatory guidance under the CARES Act or additional legislation enacted by Congress in connection with the COVID-19 pandemic could impact our tax provision in future periods.

21

Valuation Allowance

The amount of our deferred tax assets considered realizable could be adjusted if projections of future taxable income are reduced or objective negative evidence in the form of a three-year cumulative loss is present or both. Should we no longer have a level of sustained profitability, excluding nonrecurring charges, we will have to rely more on our future projections of taxable income to determine if we have an adequate source of taxable income for the realization of our deferred tax assets, namely NOL carryforwards and tax credit carryforwards. This may result in the need to record a valuation allowance against all or a portion of our deferred tax assets.

Effective Tax Rate

We have historically calculated the provision for (benefit from) income taxes during interim reporting periods by applying a full year estimated AETR to income (loss) before income taxes, excluding infrequent or unusual discrete items, for the reporting period. For the six months ended June 30, 2020, we determined that using an AETR would not provide a reliable estimate of income taxes due to small changes in our projected income (loss) before income taxes resulting in significant changes in the estimated AETR. Thus, we concluded to use a discrete effective tax rate, which treats the year-to-date period as an annual period, to calculate income taxes for the six months ended June 30, 2020. The resulting year-to date effective tax rate for the six months ended June 30, 2020 did not significantly differ from our statutory rate. We will continue to evaluate interim income tax estimates using an estimated AETR in subsequent quarters and will only use a discrete effective tax rate if warranted.

Unrecognized Tax Benefits

As of June 30, 2020, we believe it is reasonably possible that $2.7 million of our unrecognized tax benefits, including penalties, interest and discontinued operations, will be reduced prior to June 30, 2021 due to the settlement of audits or the expiration of statutes of limitations or both. However, due to the uncertain and complex application of the tax regulations, it is possible that the ultimate resolution of these matters may result in liabilities that could materially differ from this estimate.

16. Earnings per Share

Basic net income (loss) per common share is computed using the two-class method, which is an earnings allocation formula that determines net income (loss) per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Under the two-class method, basic net income (loss) per common share is determined by dividing net income (loss), after deducting amounts allocated to participating securities, by the weighted average number of common shares outstanding for the period. Participating securities include unvested restricted stock and stock-settled restricted stock units that have nonforfeitable rights to receive dividends or dividend equivalents, whether paid or unpaid. During periods of net loss, no effect is given to participating securities because they do not have a contractual obligation to participate in our losses.

Diluted net income (loss) per common share is computed using the weighted average number of shares outstanding adjusted for the incremental common stock equivalents attributed to outstanding options, performance-based restricted stock units and stock to be issued pursuant to our employee stock purchase plan unless their effect would be anti-dilutive.

22

The following table shows the calculation for net income (loss) attributable to common stockholders, which is used in the calculation of basic and diluted net income (loss) per common share (in thousands):

	Three Months Ended				Six Months Ended

17. Derivatives

We are exposed to market risks associated with changes in the variable interest rate of our Credit Facility. We use derivative instruments to manage our exposure to fluctuations in this variable interest rate and thereby minimize the risks and costs associated with financial activities. We do not use derivative instruments for trading or other speculative purposes.

23

As of June 30, 2020, we had $300.0 million notional value of interest rate swaps outstanding, which expire in March 2022 and were entered into to offset changes in expected cash flows due to fluctuations in the associated variable interest rates. The counterparties to our derivative agreements are major financial institutions. We monitor the credit quality of these financial institutions and do not expect nonperformance by any counterparty, although such nonperformance could have a material adverse effect on us. We have no collateral posted for the derivative instruments.

We have designated these interest rate swaps as cash flow hedging instruments. Changes in the fair value of the interest rate swaps are recognized as a component of other comprehensive income (loss) until the hedged transaction affects earnings. At that time, amounts are reclassified into earnings to interest expense, the same statement of operations line item to which the earnings effect of the hedged item is recorded. Cash flows from derivatives designated as hedges are classified in our condensed consolidated statements of cash flows under the same category as the cash flows from the underlying assets, liabilities or anticipated transactions unless the derivative contract contains a significant financing element; in this case, the cash settlements for these derivatives are classified as cash flows from financing activities.

We expect the hedging relationship to be highly effective as the interest rate swap terms substantially coincide with the hedged item and are expected to offset changes in expected cash flows due to fluctuations in the variable rate. We perform quarterly qualitative prospective and retrospective hedge effectiveness assessments unless facts and circumstances related to the hedging relationships change such that we can no longer assert qualitatively that the cash flow hedge relationships were and continue to be highly effective. We estimate that $4.7 million of the deferred pre-tax loss attributable to interest rate swaps included in accumulated other comprehensive loss at June 30, 2020 will be reclassified into earnings as interest expense at then-current values during the next 12 months as the underlying hedged transactions occur.

As of June 30, 2020, the weighted average effective fixed interest rate on our interest rate swaps was 1.8%.

The following table presents the effect of our derivative instruments designated as cash flow hedging instruments on our condensed consolidated balance sheets (in thousands):

18. Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

On a quarterly basis, our interest rate swap derivative instruments are valued based on the income approach (discounted cash flow) using market observable inputs, including LIBOR forward curves. These fair value measurements are classified as Level 2. The following table presents our derivative asset and liability measured at fair value on a recurring basis, with pricing levels as of the date of valuation (in thousands):

	June 30, 2020		December 31, 2019
Derivative asset	$	—	$	12
Derivative liability		8,746		1,768

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Goodwill

In the first quarter of 2020, we determined that the significant deterioration in global macroeconomic conditions caused by the COVID-19 pandemic was an indicator of potential impairment of our goodwill, and we performed a quantitative impairment test as of March 31, 2020 that resulted in a $99.8 million impairment of our goodwill. Significant estimates used in our impairment analysis included cash flow forecasts, our estimate of the market’s weighted average cost of capital and market multiples, which are Level 3 inputs. See Note 7 (“Goodwill”) for further details of the valuation methodology used in connection with the goodwill impairment.

Compressors

During the six months ended June 30, 2020, we recorded nonrecurring fair value measurements related to our idle and previously-culled compressors. Our estimate of the compressors’ fair value was primarily based on the expected net sale proceeds compared to other fleet units we recently sold and/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. We discounted the expected proceeds, net of selling and other carrying costs, using a weighted average disposal period of four years. These fair value measurements are classified as Level 3.

The fair value of our impaired compressors as of June 30, 2020 and December 31, 2019 was as follows:

	June 30, 2020		December 31, 2019
Impaired compressors	$	2,324	$	5,859

The unobservable inputs used to develop the above fair value measurements were weighted by the relative fair value of the compressors being measured. Additional quantitative information related to our significant unobservable inputs as of June 30, 2020 follows:

	Range	Weighted Average
Estimated net sale proceeds (1)	$0 - $372 per horsepower	$21 per horsepower

(1) Weighted average is calculated based on an estimated discount for market liquidity of 77%.

See Note 13 (“Long-Lived Asset Impairment”) for further details.

25

Other Financial Instruments

The carrying amounts of our cash, receivables and payables approximate fair value due to the short-term nature of those instruments.

The carrying amount of borrowings outstanding under our Credit Facility approximates fair value due to its variable interest rate. The fair value of these outstanding borrowings is a Level 3 measurement.

The fair value of our fixed rate debt is estimated using yields observable in active markets, which are Level 2 inputs, and was as follows (in thousands):

	June 30, 2020		December 31, 2019
Carrying amount of fixed rate debt (1)	$	984,937	$	1,329,549
Fair value of fixed rate debt		932,000		1,400,000

(1) Carrying amounts are shown net of unamortized debt discounts and unamortized deferred financing costs. See Note 9 (“Long-Term Debt”).

19. Stock-Based Compensation

Stock-based compensation expense consisted of the following during the three and six months ended June 30, 2020 and 2019 (in thousands):

	Three Months Ended				Six Months Ended
	June 30,				June 30,
	2020		2019		2020		2019
Equity awards	$	2,772	$	1,512	$	5,778	$	3,869
Liability awards		842		640		294		1,606
Total stock-based compensation expense	$	3,614	$	2,152	$	6,072	$	5,475

The following table presents restricted stock, restricted stock unit, performance-based restricted stock unit and cash-settled performance unit activity during the six months ended June 30, 2020 (shares in thousands):

		Weighted
		Average
		Grant Date
		Fair Value
	Shares	Per Share
Non-vested awards, December 31, 2019	2,022	$	10.25
Granted	1,412		9.47
Vested	(358)		9.45
Canceled	(59)		10.18
Non-vested awards, June 30, 2020 (1)	3,017		9.98

(1) Non-vested awards as of June 30, 2020 are comprised of 529,000 cash-settled restricted stock units and cash-settled performance units and 2,488,000 restricted stock and stock-settled performance units.

As of June 30, 2020, we expect $18.9 million of unrecognized compensation cost related to unvested restricted stock, stock-settled restricted stock units, performance units, cash-settled restricted stock units and cash-settled performance units to be recognized over the weighted average period of 2.0 years.

26

2020 Plan

The 2020 Plan was adopted in April 2020 and provides for the granting of stock options, restricted stock, restricted stock units, stock appreciation rights, performance awards, other stock-based awards and dividend equivalent rights to employees, directors and consultants of Archrock. Under the 2020 Plan, the maximum number of shares of common stock available for issuance is 8,500,000. Each stock-settled award granted under the 2020 Plan reduces the number of shares available for issuance by one share. No additional grants may be made under the 2013 Plan following the adoption of the 2020 Plan. Previous grants made under the 2013 Plan continue to be governed by that plan and the applicable award agreements.

20. Commitments and Contingencies

Performance Bonds

In the normal course of business we have issued performance bonds to various state authorities that ensure payment of certain obligations. We have also issued a bond to protect our 401(k) retirement plan against losses caused by acts of fraud or dishonesty. The bonds have expiration dates in 2020 through the fourth quarter of 2022 and maximum potential future payments of $2.2 million. As of June 30, 2020, we were in compliance with all obligations to which the performance bonds pertain.

Tax Matters

We are subject to a number of state and local taxes that are not income-based. As many of these taxes are subject to audit by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount of the liability. As of June 30, 2020 and December 31, 2019, we accrued $2.6 million and $2.5 million, respectively, for the outcomes of non-income-based tax audits. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We believe the likelihood is remote that the impact of potential unasserted claims from non-income-based tax audits could be material to our consolidated financial position, but it is possible that the resolution of future audits could be material to our consolidated results of operations or cash flows.

Subject to the provisions of the tax matters agreement between Exterran Corporation and us, both parties agreed to indemnify the primary obligor of any return for tax periods beginning before and ending before or after the Spin-off (including any ongoing or future amendments and audits for these returns) for the portion of the tax liability (including interest and penalties) that relates to their respective operations reported in the filing. The tax contingencies mentioned above relate to tax matters for which we are responsible in managing the audit. As of June 30, 2020 and December 31, 2019, we had an indemnification liability (including penalties and interest), in addition to the tax contingency above, of $1.6 million and $2.8 million, respectively, for our share of non-income-based tax contingencies related to audits being managed by Exterran Corporation.

Insurance Matters

Our business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of natural gas or well fluids and fires or explosions. As is customary in our industry, we review our safety equipment and procedures and carry insurance against some, but not all, risks of our business. Our insurance coverage includes property damage, general liability and commercial automobile liability and other coverage we believe is appropriate. We believe that our insurance coverage is customary for the industry and adequate for our business; however, losses and liabilities not covered by insurance would increase our costs.

27

Additionally, we are substantially self-insured for workers’ compensation and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to the deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. We are also self-insured for property damage to our offshore assets.

Litigation and Claims

In the ordinary course of business, we are involved in various pending or threatened legal actions. While we are unable to predict the ultimate outcome of these actions, we believe that any ultimate liability arising from any of these actions will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to pay dividends. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to pay dividends.

21. Related Party Transactions

In connection with the closing of the Elite Acquisition, we issued 21.7 million shares of our common stock to JDH Capital, an affiliate of our customer Hilcorp. As long as JDH Capital, together with affiliates of Hilcorp, owns at least 7.5% of our outstanding common stock, it will have the right to designate one director to our Board of Directors. In August 2019, Jeffery D. Hildebrand, founder and executive chairman of Hilcorp, was elected to our Board of Directors. Mr. Hildebrand receives no compensation for his role as a director. As of June 30, 2020, JDH Capital owned 14.2% of our outstanding common stock.

Revenue from Hilcorp and affiliates was $10.2 million and $4.9 million during the three months ended June 30, 2020 and 2019, respectively, and $20.8 million and $10.4 million during the six months ended June 30, 2020 and 2019, respectively. Accounts receivable, net due from Hilcorp and affiliates was $4.0 million and $5.1 million as of June 30, 2020 and December 31, 2019, respectively.

22. Segments

We manage our business segments primarily based on the type of product or service provided. We have two segments which we operate within the U.S.: contract operations and aftermarket services. The contract operations segment primarily provides natural gas compression services to meet specific customer requirements. The aftermarket services segment provides a full range of services to support the compression needs of customers, from parts sales and normal maintenance services to full operation of a customer’s owned assets.

We evaluate the performance of our segments based on gross margin for each segment. Revenue includes only sales to external customers.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited Financial Statements and the notes thereto included in this Quarterly Report on Form 10-Q and in conjunction with our 2019 Form 10-K.

Overview

We are an energy infrastructure company with a pure-play focus on midstream natural gas compression. We are the leading provider of natural gas compression services to customers in the oil and natural gas industry throughout the U.S. and a leading supplier of aftermarket services to customers that own compression equipment in the U.S. We operate in two business segments: contract operations and aftermarket services. Our contract operations services primarily include designing, sourcing, owning, installing, operating, servicing, repairing and maintaining our owned fleet of natural gas compression equipment to provide natural gas compression services to our customers. In our aftermarket services business, we sell parts and components and provide operations, maintenance, overhaul and reconfiguration services to customers who own compression equipment.

Recent Business Developments

2022 Notes Redemption

On April 1, 2020, we repaid the 2022 Notes with borrowings from our Credit Facility. See Note 9 (“Long-Term Debt”) to our Financial Statements for further details of this transaction.

COVID-19 Pandemic

During the six months ended June 30, 2020, the COVID-19 pandemic caused a deterioration in global macroeconomic conditions, including a collapse in the demand for oil coupled with an oversupply of oil in the first quarter, which commenced substantial spending cuts by our customers and a decline in production in the second quarter. This global response to the pandemic has significantly impacted our market capitalization, revenue and cash flows. Though demand has shown modest improvement in the second quarter as economies have started to reopen, much uncertainty still exists surrounding the timing of a full and sustained recovery.

The key driver of our business is the production of U.S. crude oil and natural gas. Approximately 70% of our operating fleet is deployed for midstream natural gas gathering applications with the remaining fleet being used in wellhead and gas lift applications to enhance oil production. Changes in oil and natural gas production spending therefore typically result in changes in demand for our services. According to the EIA’s July 2020 Short-Term Energy Outlook, both crude oil and dry natural gas production are now expected to decline in 2020 and 2021 as the result of the decrease in demand and commodity prices. U.S. crude oil production is estimated to decrease 5% in 2020 and decline an additional 5% in 2021. U.S. dry natural gas production is estimated to decrease 3% in 2020 and decline an additional 6% in 2021.

Substantial spending cuts for 2020 have been announced by our customers as a result of the significant declines in oil and natural gas prices and demand; however, the timing of the full impact of the spending cuts on production remains difficult to predict, as do the magnitude and duration of the pandemic and resulting economic downturn. In anticipation of lower customer activity levels, we implemented a plan in the second quarter of 2020 to reduce our annual operating, corporate and capital costs by between $75 million and $85 million. Horsepower, utilization and revenue experienced declines in the second quarter and are expected to remain at lower levels through 2020 as compared to 2019 in both our contract operations and aftermarket services businesses.

The impact of the COVID-19 pandemic on our 2020 results is primarily visible in the $99.8 million non-cash impairment of our goodwill and the impairment’s resulting impact on income taxes. Revenue, cost of sales, long-lived asset impairment and restructuring charges were also significantly impacted. See “Financial Results of Operations” below and Note 7 (“Goodwill”), Note 13 (“Long-Lived Asset Impairment”), Note 14 (“Restructuring Charges”) and Note 15 (“Income Taxes”) to our Financial Statements for further discussion.

Non-GAAP Financial Measures

Management uses a variety of financial and operating metrics to analyze our performance. These metrics are significant factors in assessing our operating results and profitability and include the non-GAAP financial measure of gross margin.

We define gross margin as total revenue less cost of sales (excluding depreciation and amortization). Gross margin is included as a supplemental disclosure because it is a primary measure used by our management to evaluate the results of revenue and cost of sales (excluding depreciation and amortization), which are key components of our operations. We believe gross margin is important because it focuses on the current operating performance of our operations and excludes the impact of the prior historical costs of the assets acquired or constructed that are utilized in those operations, the indirect costs associated with our SG&A activities, our financing methods and income taxes. In addition, depreciation and amortization may not accurately reflect the costs required to maintain and replenish the operational usage of our assets and therefore may not portray the costs of current operating activity. As an indicator of our operating performance, gross margin should not be considered an alternative to, or more meaningful than, net income (loss) as determined in accordance with GAAP. Our gross margin may not be comparable to a similarly-titled measure of other entities because other entities may not calculate gross margin in the same manner.

Gross margin has certain material limitations associated with its use as compared to net income (loss). These limitations are primarily due to the exclusion of SG&A, depreciation and amortization, impairments, restatement and other charges, restructuring charges, interest expense, debt extinguishment loss, transaction-related costs, gain (loss) on sale of assets, net, other income (loss), net, provision for (benefit from) income taxes and loss from discontinued operations, net of tax. Because we intend to finance a portion of our operations through borrowings, interest expense is a necessary element of our costs and our ability to generate revenue. Additionally, because we use capital assets, depreciation expense is a necessary element of our costs and our ability to generate revenue and SG&A is necessary to support our operations and required corporate activities. To compensate for these limitations, management uses this non-GAAP measure as a supplemental measure to other GAAP results to provide a more complete understanding of our performance.

Financial Results of Operations

Summary of Results

Revenue. Revenue was $220.3 million and $238.4 million during the three months ended June 30, 2020 and 2019, and $470.0 million and $474.5 million during the six months ended June 30, 2020 and 2019, respectively. The decrease in revenue during the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was due to a decrease in revenue from our aftermarket services business.

The decrease in revenue during the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was due to a decrease in revenue from our aftermarket services business, which was largely offset by an increase in revenue from our contract operations business.

See “Contract Operations” and “Aftermarket Services” below for further details.

Net income (loss). We had a net loss of $30.4 million and net income of $11.4 million during the three months ended June 30, 2020 and 2019, respectively, and a net loss of $91.6 million and net income of $30.9 million during the six months ended June 30, 2020 and 2019, respectively.

The change from net income to net loss during the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was primarily driven by increases in long-lived asset impairment, depreciation and amortization and restructuring charges, a decrease in gross margin from our aftermarket services business and the change in (gain) loss on sale of assets, net, partially offset by the change in provision for (benefit from) income taxes, an increase in gross margin from our contract operations business and a decrease in transaction-related costs.

The change from net income to net loss during the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily driven by goodwill impairment of $99.8 million, increases in long-lived asset impairment, depreciation and amortization, interest expense and restructuring charges and a decrease in gross margin from our aftermarket services business, partially offset by increases in benefit from income taxes and gross margin from our contract operations business and a decrease in transaction-related costs.

Gross margin percentage (1)		66	%		62	%	4	%

(1) Defined as gross margin divided by revenue.

During the three months ended June 30, 2020, revenue included the benefit from significant horsepower additions in the second half of 2019, including the Elite Acquisition completed in August 2019, which was partially offset by the disposition of other horsepower in 2019 and in the first half of this year. In addition, revenue decreased as a result of returns of horsepower due to the market downturn and a decrease in contract operations rates. The decrease in rates was driven by customer shifts to standby status and rate concessions given to customers impacted by the COVID-19 pandemic.

Gross margin and gross margin percentage increased during the three months ended June 30, 2020 compared to the three months ended June 30, 2019 primarily due to decreases in costs to mobilize compression packages, maintenance and lube oil expense, which were driven by the decreases in operating horsepower mentioned above. These decreases were partially offset by increases in maintenance and lube oil expense associated with the operating horsepower acquired in the Elite Acquisition.

Selling, general and administrative. SG&A was flat during the three months ended June 30, 2020 compared to the three months ended June 30, 2019 as the result of several offsetting factors. SG&A increased $1.6 million in bad debt expense and $1.1 million in sales and use and miscellaneous taxes. These increases were offset by decreases of $1.2 million in professional expenses, $0.7 million in compensation and benefits and $0.7 million in employee travel and meeting expense.

Depreciation and amortization. The increase in depreciation and amortization expense during the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was primarily due to an increase in depreciation expense associated with fixed assets acquired in the Elite Acquisition as well as other fixed asset additions during 2019, partially offset by a decrease in depreciation expense resulting from assets reaching the end of their depreciable lives as well as the impact of asset impairments and compression asset sales during 2019.

Long-lived asset impairment. During the three months ended June 30, 2020 and 2019, we reviewed the future deployment of our idle compressors for units that were not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. In addition, we evaluated for impairment idle units that had been culled from our fleet in prior years and were available for sale. See Note 13 (“Long-Lived Asset Impairment”) to our Financial Statements for further details.

The following table presents the results of our impairment review, as recorded to our contract operations segment (dollars in thousands):

	Three Months Ended
	June 30,
	2020		2019
Idle compressors retired from the active fleet		450		160
Horsepower of idle compressors retired from the active fleet		184,000		41,000
Impairment recorded on idle compressors retired from the active fleet	$	55,210	$	8,632

Restructuring charges. We recorded $2.4 million of severance costs related to restructuring activities during the three months ended June 30, 2020. See Note 14 (“Restructuring Charges”) to our Financial Statements for further details.

Interest expense. The slight decrease in interest expense during the three months ended June 30, 2020 compared to the three months ended June 30, 2019 was due to a decrease in the weighted average effective interest rate, which was offset by an increase in the average outstanding balance of long-term debt.

34

Debt extinguishment loss. We recorded a debt extinguishment loss of $4.0 million during the three months ended June 30, 2020 as a result of the redemption of the 2022 Notes. We recorded a debt extinguishment loss of $3.7 million during the three months ended June 30, 2019 as a result of the redemption of the 2021 Notes. See Note 9 (“Long-Term Debt”) to our Financial Statements for further details.

Transaction-related costs. We incurred $2.7 million of financial advisory, legal and other professional fees during the three months ended June 30, 2019 related primarily to the Elite Acquisition. 

(Gain) loss on sale of assets, net. The change in gain (loss) on sale of assets, net was primarily due to a $2.9 million loss on compression assets sold during the three months ended June 30, 2020 compared to a $1.3 million gain on compression assets sold during the three months ended June 30, 2019.

Effective tax rate		21	%		9	%	12	%

The change in provision for (benefit from) income taxes was primarily due to the tax effect of the decrease in book income during the three months ended June 30, 2020 compared to the three months ended June 30, 2019, partially offset by a reduction in a valuation allowance recorded during the three months ended June 30, 2019. See Note 15 (“Income Taxes”) to our Financial Statements for further details of the tax impact on the decrease in book income.

Gross margin percentage		64	%		61	%	3	%

During the six months ended June 30, 2020, revenue included the benefit from significant horsepower additions in the second half of 2019, including the Elite Acquisition completed in August 2019, which was partially offset by the disposition of other horsepower in 2019 and the first half of this year. In addition, revenue increased due to an increase in contract operations rates year over year, which was the net result of increased customer demand in 2019, partially offset by an increase in units on standby status and rate concessions given to customers impacted by the COVID-19 pandemic in the second quarter of 2020. These increases were partially offset by a decrease in revenue related to returns of horsepower due to the market downturn.

Gross margin and gross margin percentage increased during the six months ended June 30, 2020 compared to the six months ended June 30, 2019 due to the overall increase in revenue mentioned above and decreases in costs to mobilize compression packages, maintenance and lube oil expense, which were driven by the decreases in operating horsepower mentioned above. These decreases were partially offset by increases in maintenance and lube oil expense associated with the operating horsepower acquired in the Elite Acquisition.

Selling, general and administrative. The increase in SG&A during the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily due to increases of $1.9 million in bad debt expense, $1.4 million in sales and use and miscellaneous taxes and $0.7 million in costs associated with software and cloud subscriptions not yet commenced in 2019, including those related to our technology transformation project and contracts acquired in the Elite Acquisition. These increases were partially offset by decreases of $1.4 million in professional expenses, $0.9 million in compensation and benefits and $0.6 million in employee travel and meeting expenses.

Depreciation and amortization. The increase in depreciation and amortization expense during the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily due to an increase in depreciation expense associated with fixed assets acquired in the Elite Acquisition as well as other fixed asset additions during 2019, partially offset by a decrease in depreciation expense resulting from assets reaching the end of their depreciable lives as well as the impact of asset impairments and compression asset sales during 2019.

Impairment recorded on idle compressor units retired from the active fleet	$	61,405	$	11,724

Goodwill impairment. During the six months ended June 30, 2020, we recorded $99.8 million of goodwill impairment due to the decline in the fair value of our contract operations reporting unit. See Note 7 (“Goodwill”) to our Financial Statements for further details.

Restructuring charges. We recorded $4.1 million of severance costs related to restructuring activities during the six months ended June 30, 2020. See Note 14 (“Restructuring Charges”) to our Financial Statements for further details.

Interest expense. The increase in interest expense during the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was due to an increase in the average outstanding balance of long-term debt, partially offset by a decrease in the weighted average effective interest rate.

Debt extinguishment loss. We recorded a debt extinguishment loss of $4.0 million during the six months ended June 30, 2020 as a result of the redemption of the 2022 Notes. We recorded a debt extinguishment loss of $3.7 million during the six months ended June 30, 2019 as a result of the redemption of the 2021 Notes. See Note 9 (“Long-Term Debt”) to our Financial Statements for further details.

Transaction-related costs. We incurred $2.9 million of financial advisory, legal and other professional fees during the six months ended June 30, 2019 related primarily to the Elite Acquisition. 

Gain on sale of assets, net. The increase in gain on sale of assets, net was primarily due to a $3.2 million gain on the March 2020 Disposition, which included a $4.8 million gain on the compression assets sold, partially offset by a $2.8 million loss on other compression assets sold during the six months ended June 30, 2020.

Other income, net. The increase in other income, net during the six months ended June 30, 2020 compared to the six months ended June 30, 2020 was primarily due to a $0.4 million decrease in indemnification expense incurred pursuant to our tax matters agreement with Exterran Corporation.

Liquidity and Capital Resources

Overview

Our ability to fund operations, finance capital expenditures and pay dividends depends on the levels of our operating cash flows and access to the capital and credit markets. Our primary sources of liquidity are cash flows generated from our operations and our borrowing availability under the Credit Facility. Our cash flow is affected by numerous factors including prices and demand for our services, oil and natural gas exploration and production spending, conditions in the financial markets and other factors. Beginning in the first quarter of 2020, the COVID-19 pandemic has caused a deterioration in global macroeconomic conditions, which has significantly impacted our estimates of future revenues and cash flows. However, we have no near-term maturities and believe that our operating cash flows and borrowings under the Credit Facility will be sufficient to meet our future liquidity needs.

We may from time to time seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors.

Capital Requirements

Our contract operations business is capital intensive, requiring significant investment to maintain and upgrade existing operations. Our capital spending is primarily dependent on the demand for our contract operations services and the availability of the type of compression equipment required for us to provide those contract operations services to our customers. Our capital requirements have consisted primarily of, and we anticipate will continue to consist of, the following:

● growth capital expenditures, which are made to expand or to replace partially or fully depreciated assets or to expand the operating capacity or revenue-generating capabilities of existing or new assets; and

● maintenance capital expenditures, which are made to maintain the existing operating capacity of our assets and related cash flows, further extending the useful lives of the assets.

The majority of our growth capital expenditures are related to the acquisition cost of new compressors that we add to our fleet. In addition to the cost of newly-acquired compressors, growth capital expenditures can also include the upgrading of major components on an existing compression package where the current configuration of the compression package is no longer in demand and the compressor is not likely to return to an operating status without the capital expenditures. These latter expenditures substantially modify the operating parameters of the compression package such that it can be used in applications for which it previously was not suited. Maintenance capital expenditures are related to major overhauls of significant components of a compression package, such as the engine, compressor and cooler, which return the components to a like-new condition, but do not modify the applications for which the compression package was designed.

We generally invest funds necessary to purchase fleet additions when our idle equipment cannot be reconfigured to economically fulfill a project’s requirements and the new equipment expenditure is expected to generate economic returns over its expected useful life that exceed our cost of capital. In response to the impact that we anticipate the COVID-19 pandemic will have on our customer demand, we decreased our planned capital expenditures for 2020, and currently plan to spend a total of approximately $130 million to $155 million, primarily consisting of approximately $70 million to $85 million for growth capital expenditures and approximately $37 million to $43 million for maintenance capital expenditures.

Financial Resources

Credit Facility

During the six months ended June 30, 2020 and 2019, the Credit Facility had an average daily balance of $675.5 million and $784.0 million, respectively. The weighted average annual interest rate on the outstanding balance under the Credit Facility, excluding the effect of interest rate swaps, was 2.7% and 4.3% at June 30, 2020 and December 31, 2019, respectively. As of June 30, 2020, there were $12.4 million letters of credit outstanding under the Credit Facility.

We must maintain certain consolidated financial ratios as defined in our Credit Facility agreement. As of June 30, 2020, the ratio requirements did not constrain our undrawn capacity and as such, $414.6 million was available for additional borrowings. As of June 30, 2020, we were in compliance with all covenants under the Credit Facility.

2022 Notes Redemption

On April 1, 2020, the 2022 Notes were redeemed at 100% of their $350.0 million aggregate principal amount plus accrued and unpaid interest of $10.5 million with borrowings from the Credit Facility. A debt extinguishment loss of $4.0 million related to the redemption was recognized in the second quarter of 2020. See Note 9 (“Long-Term Debt”) to our Financial Statements for further details.

Cash Flows

Our cash flows from operating, investing and financing activities, as reflected in our condensed consolidated statements of cash flows, are summarized below (in thousands):

	Six Months Ended
	June 30,

Net cash provided by (used in):
Operating activities	$	167,074	$	148,663

Financing activities		(85,866)		60,084
Net decrease in cash and cash equivalents	$	(1,480)	$	(3,595)

Operating Activities

The increase in net cash provided by operating activities during the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily due to decreases in accounts receivable, costs of sales, contract costs and transaction-related costs. These cash inflows were partially offset by the receipt of cash proceeds in the first quarter of 2019 pursuant to a settlement of certain sales and use tax audits, a decrease in revenue and increases in accounts payable and other liabilities, deferred revenue, restructuring charges and interest paid on our debt instruments.

Investing Activities

The decrease in net cash used in investing activities during the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily due to a $121.7 million decrease in capital expenditures and the receipt of proceeds of $24.2 million from the March 2020 Disposition, partially offset by a $16.9 million decrease in proceeds from other sales of property, plant and equipment.

39

Financing Activities

The change in net cash provided by (used in) financing activities during the six months ended June 30, 2020 compared to the six months ended June 30, 2019 was primarily due to $40.0 million of net repayments of long-term debt in 2020 compared to $103.0 million of net borrowings in 2019 and a $9.9 million increase in dividends paid to stockholders, partially offset by a $7.9 million decrease in payments for debt issuance costs.

Dividends

On July 29, 2020, our Board of Directors declared a quarterly dividend of $0.145 per share of common stock to be paid on August 14, 2020 to stockholders of record at the close of business on August 10, 2020. Any future determinations to pay cash dividends to our stockholders will be at the discretion of our Board of Directors and will be dependent upon our financial condition, results of operations and credit and loan agreements in effect at that time and other factors deemed relevant by our Board of Directors.

Off-Balance Sheet Arrangements

For information on our obligations with respect to letters of credit and performance bonds see Note 9 (“Long-Term Debt”) and Note 20 (“Commitments and Contingencies”), respectively, to our Financial Statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk associated with changes in the variable interest rate of our Credit Facility. We use derivative instruments to manage our exposure to fluctuations in this variable interest rate and thereby minimize the risks and costs associated with financing activities. We do not use derivative instruments for trading or other speculative purposes.

As of June 30, 2020 and December 31, 2019, after taking into consideration interest rate swaps, we had $523.0 million and $113.0 million, respectively, of outstanding indebtedness that was effectively subject to variable interest rates. A 1% increase in the effective interest rate on our outstanding debt subject to variable interest rates at June 30, 2020 and December 31, 2019 would have resulted in an annual increase in our interest expense of $5.2 million and $1.1 million, respectively.

See Note 17 (“Derivatives”) to our Financial Statements for further information regarding our use of interest rate swaps in managing our exposure to interest rate fluctuations.

Item 4. Controls and Procedures

This Item 4 includes information concerning the controls and controls evaluation referred to in the certifications of our Chief Executive Officer and Chief Financial Officer required by Rule 13a-14 of the Exchange Act included in this Quarterly Report as Exhibits 31.1 and 31.2.

Management’s Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are designed to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that such information is accumulated and communicated to management to allow timely decisions regarding required disclosures.

40

As of the end of the period covered by this Quarterly Report on Form 10-Q, our principal executive officer and principal financial officer evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act), which are designed to provide reasonable assurance that we are able to record, process, summarize and report the information required to be disclosed in our reports under the Exchange Act within the time periods specified in the rules and forms of the SEC. Based on the evaluation, as of June 30, 2020 our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed in reports that we file or submit under the Exchange Act is accumulated and communicated to management, and made known to our principal executive officer and principal financial officer, on a timely basis to ensure that it is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

41

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

In the ordinary course of business, we are involved in various pending or threatened legal actions. While we are unable to predict the ultimate outcome of these actions, we believe that any ultimate liability arising from any of these actions will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to pay dividends. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to pay dividends.

Item 1A. Risk Factors

The following risk factors became significant to us in the first half of 2020 and should be read in conjunction with the risk factors previously disclosed in our 2019 Form 10-K.

The COVID-19 pandemic is expected to significantly reduce demand for our services, and may have a material adverse impact on our financial condition, results of operations and cash flows.

The effects of the COVID-19 pandemic, including actions taken by businesses and governments, have resulted in a significant and swift reduction in U.S. economic activity. These effects have materially adversely affected the demand for oil and, to a lesser extent, natural gas, and are expected to have a negative impact on demand for our services and products. The collapse in the demand for oil caused by this unprecedented global health and economic crisis, coupled with oil oversupply, is expected to adversely impact the demand for our services, which in turn could adversely impact our financial condition, results of operations and cash flows.

While the magnitude and duration of potential social, economic and labor instability as a direct result of the COVID-19 pandemic cannot be estimated at this time, we are closely monitoring the effects of the pandemic on commodity demands and on our customers, as well as on our operations and employees. These effects may include adverse revenue and net income effects; disruptions to our operations and supply chain; customer shutdowns of oil and gas exploration and production; employee impacts from illness, school closures and other community response measures; and temporary inaccessibility or closures of our facilities or the facilities of our customers and suppliers.

The extent to which our operating and financial results are affected by the COVID-19 pandemic will depend on various factors and consequences beyond our control, such as the duration and scope of the pandemic; additional actions by businesses and governments in response to the pandemic; and the speed and effectiveness of responses to combat the virus. The COVID-19 pandemic, and the volatile regional and global economic conditions stemming from the pandemic, could also aggravate the other risk factors that we identify in our Annual Report on Form 10-K for the fiscal year ended December 31, 2019. The COVID-19 pandemic also may materially adversely affect our operating and financial results in a manner that is not currently known to us or that we do not currently consider to present significant risks to our operations.

42

Our ability to use NOLs to offset future income may be limited.

Our ability to use any NOLs generated by us could be substantially limited if we were to experience an “ownership change” as defined under Section 382 of the Code. In general, an “ownership change” would occur if our “5-percent stockholders,” as defined under Section 382 of the Code, including certain groups of persons treated as “5-percent stockholders,” collectively increased their ownership in us by more than 50 percentage points over a rolling three-year period. An ownership change can occur as a result of a public offering of our common stock, as well as through secondary market purchases of our common stock and certain types of reorganization transactions. We have experienced ownership changes, which may result in an annual limitation on the use of its pre-ownership change NOLs (and certain other losses and/or credits) equal to the equity value of our stock immediately before the ownership change, multiplied by the long-term tax-exempt rate for the month in which the ownership change occurs. Market volatility due to reduced demand from the COVID-19 pandemic and oil oversupply may cause increased interest in our common stock, which may result in an additional ownership change. Due to the COVID-19 pandemic, the U.S. Federal Reserve has lowered the long-term tax-exempt rate. Additionally, our equity value has decreased due to the above-mentioned impacts of the COVID-19 pandemic and oil oversupply. Both of these changes could further limit our use of pre-ownership change NOLs if we experienced an additional ownership change. Furthermore, the IRS has recently proposed regulations that would prevent us from using unrealized built-in gains to increase this limitation. If these regulations were finalized and we experienced an ownership change our ability to use our NOLs may be limited. Such a limitation could, for any given year, have the effect of increasing the amount of our U.S. federal income tax liability, which would negatively impact the amount of after-tax cash available for distribution to our stockholders and our financial condition.

2. Recent Accounting Developments

Accounting Standards Updates Implemented

Credit Losses

In June 2016, the FASB issued ASU 2016-13, which changes the impairment model for financial assets measured at amortized cost and certain other instruments, and requires entities to use a new current expected credit loss model that results in recognition of expected losses over the contractual life of an asset. We adopted ASU 2016-13 on January 1, 2020 using the modified retrospective approach. The adoption resulted in a $0.2 million decrease in our allowance for credit losses and a corresponding pre-tax cumulative effect adjustment to retained earnings in our condensed consolidated balance sheet at January 1, 2020. Comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

Our financial assets measured at amortized cost consist of cash equivalents and trade receivables from revenue transactions within the scope of ASC 606 Revenue. We believe our temporary cash investments have a zero loss expectation because we maintain minimal balances in our cash investment accounts and have no history of loss. Trade accounts receivable are due from companies of varying size engaged principally in oil and natural gas activities throughout the U.S. We review the financial condition of customers prior to extending credit and generally do not obtain collateral for trade receivables. Payment terms are on a short-term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ financial resources, the nature of the products and services we provide and the terms of our customer agreements.

Due to the short-term nature of our trade receivables, we consider the amortized cost to be the same as the carrying amount of the receivable, excluding the allowance for credit losses. We recognize an allowance for credit losses when a receivable is recorded, even when the risk of loss is remote. We utilize an aging schedule to determine our allowance for credit losses, and measure expected credit losses on a collective (pool) basis when similar risk characteristics exist. We rely primarily on ratings assigned by external rating agencies and credit monitoring services to assess credit risk and aggregate customers first by low, medium or high risk asset pools, and then by delinquency status. We also consider the internal risk associated with geographic location and the services we provide to the customer when determining asset pools. If a customer does not share similar risk characteristics with other customers, we evaluate the customer’s outstanding trade receivables for expected credit losses on an individual basis. Trade receivables evaluated individually are not included in our collective assessment. Each reporting period, we reassess our customers’ risk profiles and determine the appropriate asset pool classification, or perform individual assessments of expected credit losses, based on the customers’ risk characteristics at the reporting date.

The contractual life of our trade receivables is primarily 30 days based on the payment terms specified in the contract. Contract operations services are generally billed monthly at the beginning of the month in which service is being provided. Aftermarket services billings typically occur when parts are delivered or service is completed. Loss rates are separately determined for each asset pool based on the length of time a trade receivable has been outstanding. We analyze two years of internal historical loss data, including the effects of prepayments, write-offs and subsequent recoveries, to determine our historical loss experience. Our historical loss information is a relevant data point for estimating credit losses, as the data closely aligns with trade receivables due from our customers. Ratings assigned by external rating agencies and credit monitoring services consider past performance and forecasts of future economic conditions in assessing credit risk. We routinely update our historical loss data to reflect our customers’ current risk profile, to ensure the historical data and loss rates are relevant to the pool of assets for which we are estimating expected credit losses. Judgement is used to determine the expected credit loss for customers that do not share similar risk characteristics with other customers, based on customer specific items such as legal proceedings, past experience with the customer and/or ongoing customer negotiations.

The following table summarizes the changes in our allowance for credit losses balance during the six months ended June 30, 2020 (in thousands):

Balance at December 31, 2019	$	2,210
Impact of adoption of ASU 2016-13 on January 1, 2020		(216)
Provision for credit losses		2,282
Write-offs charged against allowance		(646)
Balance at June 30, 2020	$	3,630

Fair Value Measurements

On January 1, 2020, we adopted ASU 2018-13, which amends the required fair value measurements disclosures related to valuation techniques and inputs used, uncertainty in measurement and changes in measurements applied. These amendments resulted in new, prospective disclosures of the range and weighted average of the significant unobservable inputs used to develop our Level 3 fair value measurements related to our idle and previously-culled compressors. The adoption of ASU 2018-13 had no impact on our condensed consolidated financial statements.

Income Taxes

On January 1, 2020, we adopted ASU 2019-12, which simplifies the accounting for income taxes by, among other things, removing certain exceptions related to the incremental approach for intraperiod tax allocation, the year-to-date loss methodology for calculating income taxes in an interim period and the recognition for deferred tax liabilities on outside basis differences. ASU 2019-12 also clarifies other aspects of the accounting for income taxes in order to improve consistency of application. The adoption of ASU 2019-12 had no impact on our condensed consolidated financial statements.

Accounting Standards Updates Not Yet Implemented

Reference Rate Reform

In March 2020, the FASB issued ASU 2020-04, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued as a result of reference rate reform. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. Entities may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. We are currently assessing the impact that ASU 2020-04 may have on our interest rate swap agreements, Credit Facility and other transactions that may be affected by reference rate reform.

March 2020 Disposition

On March 1, 2020, we completed the sale of certain contract operations customer service agreements and approximately 200 compressors, comprising approximately 35,000 horsepower, used to provide compression services under those agreements as well as other assets used to support the operations. We allocated customer and contract-related intangible assets and goodwill based on a ratio of the horsepower sold relative to the total horsepower of the asset group. We recognized a gain on the sale of $3.2 million in gain (loss) on sale of assets, net in our condensed consolidated statements of operations during the six months ended June 30, 2020.

Elite Acquisition

On August 1, 2019, we completed the Elite Acquisition whereby we acquired from Elite Compression substantially all of its assets, including a fleet of predominantly large compressors comprising approximately 430,000 horsepower, vehicles, real property and inventory, and certain liabilities for aggregate consideration consisting of $214.0 million in cash and 21.7 million shares of common stock with an acquisition date fair value of $225.9 million. The cash portion of the acquisition was funded with borrowings on the Credit Facility.

The Elite Acquisition was accounted for using the acquisition method, which requires, among other things, assets acquired and liabilities assumed to be recorded at their fair value on the acquisition date. The excess of the consideration transferred over those fair values is recorded as goodwill. The following table summarizes the purchase price allocation based on the estimated fair values of the acquired assets and liabilities as of the acquisition date (in thousands):

Accounts receivable	$	9,007
Inventory		7,987
Other current assets		608
Property, plant and equipment		286,158
Operating lease ROU assets		682
Goodwill		100,598
Intangible assets		40,237
Accounts payable, trade		(2,079)
Accrued liabilities		(2,973)
Operating lease liabilities		(326)
Purchase price	$	439,899

Our valuation methodology and significant inputs for fair value measurements are detailed by asset class below. The fair value measurements for property, plant and equipment and intangible assets are based on significant inputs that are not observable in the market and therefore represent Level 3 measurements.

Goodwill

The goodwill resulting from the acquisition is attributable to the expansion of our services in various regions in which we currently operate and was allocated to our contract operations segment. All of the goodwill recorded for this acquisition is expected to be deductible for U.S. federal income tax purposes.

Property, Plant and Equipment

The property, plant and equipment is primarily comprised of compression equipment that will be depreciated on a straight-line basis over an estimated average remaining useful life of 15 years. The fair value of the property, plant and equipment was determined using the cost approach, whereby we estimated the replacement cost of the assets by evaluating recent purchases of similar assets or published data, and then adjusted replacement cost for physical deterioration and functional and economic obsolescence, as applicable.

Intangible Assets

The intangible assets consist of customer relationships that have an estimated useful life of 15 years. The amount of intangible assets and their associated useful life were determined based on the period over which the assets are expected to contribute directly or indirectly to our future cash flows. The fair value of the identifiable intangible assets was determined using the multi-period excess earnings method, which is a specific application of the discounted cash flow method, an income approach, whereby we estimated and then discounted the future cash flows of the intangible asset by adjusting overall business revenue for attrition, obsolescence, cost of sales, operating expenses, taxes and the required returns attributable to other contributory assets acquired. Significant estimates made in arriving at expected future cash flows included our expected customer attrition rate and the amount of earnings attributable to the assets. To discount the estimated future cash flows, we utilized a discount rate that was at a premium to our weighted average cost of capital to reflect the less liquid nature of the customer relationships relative to the tangible assets acquired.

Unaudited Pro Forma Financial Information

Unaudited pro forma financial information for the three and six months ended June 30, 2019 was derived by adjusting our historical financial statements in order to give effect to the assets and liabilities acquired in the Elite Acquisition. The Elite Acquisition is presented in this unaudited pro forma financial information as though the acquisition occurred as of January 1, 2019, and reflects the following:

● the acquisition of substantially all of Elite Compression’s assets, including a compression fleet of approximately 430,000 horsepower, vehicles, real property and inventory, and certain liabilities; and

● borrowings of $214.0 million under the Credit Facility for cash consideration exchanged in the acquisition; and

● the exclusion of $2.5 million of financial advisory, legal and other professional fees incurred related to the acquisition and recorded to transaction-related costs in our condensed consolidated statements of operations during each of the three and six months ended June 30, 2019.

The unaudited pro forma financial information below is presented (in thousands) for informational purposes only and is not necessarily indicative of our results of operations that would have occurred had the transaction been consummated at the beginning of the period presented, nor is it necessarily indicative of future results.

Discontinued Operations

4. Discontinued Operations

In 2015 we completed the Spin-off. In order to effect the Spin-off and govern our relationship with Exterran Corporation after the Spin-off, we entered into several agreements with Exterran Corporation which include, but are not limited to, the separation and distribution agreement and the tax matters agreement.

The separation and distribution agreement specifies our right to promptly receive payments from Exterran Corporation based on a notional amount corresponding to payments received by Exterran Corporation from PDVSA in respect of the sale of Exterran Corporation’s previously-nationalized assets after such amounts are collected by Exterran Corporation. During the three months ended June 30, 2020, we received $0.7 million from Exterran Corporation pursuant to this term of the separation and distribution agreement. We also entered into an assignment from Exterran Corporation so that any future payments by PDVSA would be received directly by us.

The tax matters agreement governs the respective rights, responsibilities and obligations of Exterran Corporation and us with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and certain other matters regarding taxes. Subject to the provisions of this agreement, we and Exterran Corporation agreed to indemnify the primary obligor of any return for tax periods beginning before and ending before or after the Spin-off (including any ongoing or future amendments and audits for these returns) for the portion of the tax liability (including interest and penalties) that relates to their respective operations reported in the filing.

As of both June 30, 2020 and December 31, 2019, we had $8.5 million of unrecognized tax benefits (including interest and penalties) related to Exterran Corporation operations prior to the Spin-off recorded to noncurrent liabilities associated with discontinued operations in our condensed consolidated balance sheets. We had an offsetting indemnification asset of $8.5 million related to these unrecognized tax benefits recorded to noncurrent assets associated with discontinued operations as of both June 30, 2020 and December 31, 2019.

The following table presents the balance sheet for our discontinued operations (in thousands):

7. Goodwill

Our goodwill was recognized in connection with the Elite Acquisition and represents the excess of consideration transferred over the fair value of the assets and liabilities acquired. All of the goodwill was allocated to our contract operations reporting unit. We review the carrying amount of our goodwill in the fourth quarter of every year, or whenever indicators of potential impairment exist, to determine if the carrying amount of our contract operations reporting unit exceeds its fair value, including the goodwill. Beginning in the first quarter of 2020, the COVID-19 pandemic caused a significant deterioration in global macroeconomic conditions, including a collapse in the demand for oil coupled with an oversupply of oil, which commenced substantial spending cuts by our customers and a decline in production. This global response to the pandemic significantly impacted our market capitalization and estimates of future revenues and cash flows, which triggered the need to perform a quantitative test of the fair value of our contract operations reporting unit as of March 31, 2020. The quantitative test determined that the carrying amount of our contract operations reporting unit exceeded its fair value and we recorded a full impairment loss on goodwill in the first quarter as a result.

Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions, which have a significant impact on the fair value determined. We determine the fair value of our reporting unit using an equal weighting of both the expected present value of future cash flows and a market approach. The present value of future cash flows is estimated using our most recent forecast and the weighted average cost of capital. The market approach uses a market multiple on the earnings before interest expense, provision for income taxes and depreciation and amortization expense of comparable peer companies. Significant estimates for our reporting unit included in our impairment analysis are our cash flow forecasts, our estimate of the market’s weighted average cost of capital and market multiples.

Hosting Arrangements

8. Hosting Arrangements

In the fourth quarter of 2018 we began a process and technology transformation project that will, among other things, upgrade or replace our existing ERP, supply chain and inventory management systems and expand the remote monitoring capabilities of our compression fleet. Included in this project are hosting arrangements that are service contracts related to the cloud migration of our ERP system and cloud services for our new mobile workforce, telematics and inventory management tools.

Certain costs incurred for the implementation of our hosting arrangements that are service contracts are capitalized and amortized on a straight-line basis over the term of the respective contract. Amortization begins in the period in which an individual component becomes ready for its intended use. As of June 30, 2020 and December 31, 2019, we capitalized $7.7 million and $5.5 million, respectively, of implementation costs related to our hosting arrangements that are service contracts to other assets in our condensed consolidated balance sheets. Accumulated amortization was $0.1 million at June 30, 2020. We recorded $0.1 million of amortization expense to SG&A in our condensed consolidated statements of operations during each of the three and six months ended June 30, 2020.

Credit Facility

As of June 30, 2020, there were $12.4 million letters of credit outstanding under the Credit Facility and the applicable margin on borrowings outstanding was 2.5%. The weighted average annual interest rate on the outstanding balance under the Credit Facility, excluding the effect of interest rate swaps, was 2.7% and 4.3% at June 30, 2020 and December 31, 2019, respectively. We incurred $0.4 million and $0.6 million in commitment fees on the daily unused amount of the Credit Facility during the three months ended June 30, 2020 and 2019, respectively, and $1.1 million during each of the six months ended June 30, 2020 and 2019.

We must maintain certain consolidated financial ratios as defined in our Credit Facility agreement. As of June 30, 2020, the ratio requirements did not constrain our undrawn capacity and as such, $414.6 million was available for additional borrowings. As of June 30, 2020, we were in compliance with all covenants under the Credit Facility agreement.

2022 Notes Redemption

On April 1, 2020, the 2022 Notes were redeemed at 100% of their $350.0 million aggregate principal amount plus accrued and unpaid interest of $10.5 million with borrowings from the Credit Facility. A debt extinguishment loss of $4.0 million related to the redemption was recognized during the three and six months ended June 30, 2020.

Performance Obligations

As of June 30, 2020, we had $416.8 million of remaining performance obligations related to our contract operations segment. We do not consider the effects of the time value of money, as the expected time between the transfer of services and payment for such services is less than one year. Our remaining performance obligations will be recognized through 2025 as follows (in thousands):

We do not disclose the aggregate transaction price for the remaining performance obligations for aftermarket services as there are no contracts with customers with an original contract term that is greater than one year.

Contract Assets and Liabilities

As of June 30, 2020 and December 31, 2019, our receivables from contracts with customers, net of allowance for credit losses, were $118.8 million and $139.4 million, respectively.

Freight billings to customers for the transport of compression assets, customer-specified modifications of compression assets and milestone billings on aftermarket services often result in a contract liability. As of June 30, 2020 and December 31, 2019, our contract liabilities were $6.9 million and $11.4 million, respectively, which were included in deferred revenue and other liabilities in our condensed consolidated balance sheets. The decrease in the contract liability balance during the six months ended June 30, 2020 was primarily due to $12.8 million recognized as revenue during the period, partially offset by revenue deferral of $8.3 million, each primarily related to freight billings and milestone billings on aftermarket services.

Asset Impairment Charges [Abstract]

Long-Lived Asset Impairment

13. Long-Lived Asset Impairment

We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, for impairment whenever events or changes in circumstances, including the removal of compressors from our active fleet, indicate that the carrying amount of an asset may not be recoverable.

We periodically review the future deployment of our idle compression assets for units that are not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. Based on these reviews, we determine that certain idle compressors should be retired from the active fleet. The retirement of these units from the active fleet triggers a review of these assets for impairment and as a result of our review, we may record an asset impairment to reduce the book value of each unit to its estimated fair value. The fair value of each unit is estimated based on the expected net sale proceeds compared to other fleet units we recently sold, a review of other units recently offered for sale by third parties or the estimated component value of the equipment we plan to use.

In connection with our review of our idle compression assets, we evaluate for impairment idle units that were culled from our fleet in prior years and are available for sale. Based on that review, we may reduce the expected proceeds from disposition and record additional impairment to reduce the book value of each unit to its estimated fair value.

In the first quarter of 2020, we determined that the impairment of our contract operations reporting unit’s goodwill was an indicator of potential impairment of the carrying amount of our long-lived assets, including our compressor fleet and associated customer and contract-based intangible assets. Accordingly, we performed a quantitative impairment test of our long-lived assets, by which we determined that they were not also impaired. No similar impairment has been indicated subsequent to the first quarter.

The following table presents the results of our impairment review as recorded to our contract operations segment (dollars in thousands):

During the first quarter of 2020, we completed a series of restructuring activities to further streamline our organization and more fully align our teams to improve our customer service and profitability. We began additional restructuring activities in the second quarter in response to the decreased activity level of our customers that resulted from the COVID-19 pandemic. We incurred severance costs of $2.4 million and $4.1 million during the three and six months ended June 30, 2020, respectively, which are reflected as restructuring charges in our condensed consolidated statements of operations.

CARES Act

On March 27, 2020, President Trump signed into law the CARES Act, which includes, among other things, refundable payroll tax credits, deferment of employer side social security payments, NOL carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. The CARES Act provisions did not have a material impact on our condensed consolidated financial statements. Future regulatory guidance under the CARES Act or additional legislation enacted by Congress in connection with the COVID-19 pandemic could impact our tax provision in future periods.

Valuation Allowance

The amount of our deferred tax assets considered realizable could be adjusted if projections of future taxable income are reduced or objective negative evidence in the form of a three-year cumulative loss is present or both. Should we no longer have a level of sustained profitability, excluding nonrecurring charges, we will have to rely more on our future projections of taxable income to determine if we have an adequate source of taxable income for the realization of our deferred tax assets, namely NOL carryforwards and tax credit carryforwards. This may result in the need to record a valuation allowance against all or a portion of our deferred tax assets.

Effective Tax Rate

We have historically calculated the provision for (benefit from) income taxes during interim reporting periods by applying a full year estimated AETR to income (loss) before income taxes, excluding infrequent or unusual discrete items, for the reporting period. For the six months ended June 30, 2020, we determined that using an AETR would not provide a reliable estimate of income taxes due to small changes in our projected income (loss) before income taxes resulting in significant changes in the estimated AETR. Thus, we concluded to use a discrete effective tax rate, which treats the year-to-date period as an annual period, to calculate income taxes for the six months ended June 30, 2020. The resulting year-to date effective tax rate for the six months ended June 30, 2020 did not significantly differ from our statutory rate. We will continue to evaluate interim income tax estimates using an estimated AETR in subsequent quarters and will only use a discrete effective tax rate if warranted.

Unrecognized Tax Benefits

As of June 30, 2020, we believe it is reasonably possible that $2.7 million of our unrecognized tax benefits, including penalties, interest and discontinued operations, will be reduced prior to June 30, 2021 due to the settlement of audits or the expiration of statutes of limitations or both. However, due to the uncertain and complex application of the tax regulations, it is possible that the ultimate resolution of these matters may result in liabilities that could materially differ from this estimate.

Earnings Per Share [Abstract]

Earnings Per Share

16. Earnings per Share

Basic net income (loss) per common share is computed using the two-class method, which is an earnings allocation formula that determines net income (loss) per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Under the two-class method, basic net income (loss) per common share is determined by dividing net income (loss), after deducting amounts allocated to participating securities, by the weighted average number of common shares outstanding for the period. Participating securities include unvested restricted stock and stock-settled restricted stock units that have nonforfeitable rights to receive dividends or dividend equivalents, whether paid or unpaid. During periods of net loss, no effect is given to participating securities because they do not have a contractual obligation to participate in our losses.

Diluted net income (loss) per common share is computed using the weighted average number of shares outstanding adjusted for the incremental common stock equivalents attributed to outstanding options, performance-based restricted stock units and stock to be issued pursuant to our employee stock purchase plan unless their effect would be anti-dilutive.

The following table shows the calculation for net income (loss) attributable to common stockholders, which is used in the calculation of basic and diluted net income (loss) per common share (in thousands):

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

17. Derivatives

We are exposed to market risks associated with changes in the variable interest rate of our Credit Facility. We use derivative instruments to manage our exposure to fluctuations in this variable interest rate and thereby minimize the risks and costs associated with financial activities. We do not use derivative instruments for trading or other speculative purposes.

As of June 30, 2020, we had $300.0 million notional value of interest rate swaps outstanding, which expire in March 2022 and were entered into to offset changes in expected cash flows due to fluctuations in the associated variable interest rates. The counterparties to our derivative agreements are major financial institutions. We monitor the credit quality of these financial institutions and do not expect nonperformance by any counterparty, although such nonperformance could have a material adverse effect on us. We have no collateral posted for the derivative instruments.

We have designated these interest rate swaps as cash flow hedging instruments. Changes in the fair value of the interest rate swaps are recognized as a component of other comprehensive income (loss) until the hedged transaction affects earnings. At that time, amounts are reclassified into earnings to interest expense, the same statement of operations line item to which the earnings effect of the hedged item is recorded. Cash flows from derivatives designated as hedges are classified in our condensed consolidated statements of cash flows under the same category as the cash flows from the underlying assets, liabilities or anticipated transactions unless the derivative contract contains a significant financing element; in this case, the cash settlements for these derivatives are classified as cash flows from financing activities.

We expect the hedging relationship to be highly effective as the interest rate swap terms substantially coincide with the hedged item and are expected to offset changes in expected cash flows due to fluctuations in the variable rate. We perform quarterly qualitative prospective and retrospective hedge effectiveness assessments unless facts and circumstances related to the hedging relationships change such that we can no longer assert qualitatively that the cash flow hedge relationships were and continue to be highly effective. We estimate that $4.7 million of the deferred pre-tax loss attributable to interest rate swaps included in accumulated other comprehensive loss at June 30, 2020 will be reclassified into earnings as interest expense at then-current values during the next 12 months as the underlying hedged transactions occur.

As of June 30, 2020, the weighted average effective fixed interest rate on our interest rate swaps was 1.8%.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

On a quarterly basis, our interest rate swap derivative instruments are valued based on the income approach (discounted cash flow) using market observable inputs, including LIBOR forward curves. These fair value measurements are classified as Level 2. The following table presents our derivative asset and liability measured at fair value on a recurring basis, with pricing levels as of the date of valuation (in thousands):

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Goodwill

In the first quarter of 2020, we determined that the significant deterioration in global macroeconomic conditions caused by the COVID-19 pandemic was an indicator of potential impairment of our goodwill, and we performed a quantitative impairment test as of March 31, 2020 that resulted in a $99.8 million impairment of our goodwill. Significant estimates used in our impairment analysis included cash flow forecasts, our estimate of the market’s weighted average cost of capital and market multiples, which are Level 3 inputs. See Note 7 (“Goodwill”) for further details of the valuation methodology used in connection with the goodwill impairment.

Compressors

During the six months ended June 30, 2020, we recorded nonrecurring fair value measurements related to our idle and previously-culled compressors. Our estimate of the compressors’ fair value was primarily based on the expected net sale proceeds compared to other fleet units we recently sold and/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. We discounted the expected proceeds, net of selling and other carrying costs, using a weighted average disposal period of four years. These fair value measurements are classified as Level 3.

The fair value of our impaired compressors as of June 30, 2020 and December 31, 2019 was as follows:

	June 30, 2020		December 31, 2019
Impaired compressors	$	2,324	$	5,859

The unobservable inputs used to develop the above fair value measurements were weighted by the relative fair value of the compressors being measured. Additional quantitative information related to our significant unobservable inputs as of June 30, 2020 follows:

	Range	Weighted Average
Estimated net sale proceeds (1)	$0 - $372 per horsepower	$21 per horsepower

(1) Weighted average is calculated based on an estimated discount for market liquidity of 77%.

See Note 13 (“Long-Lived Asset Impairment”) for further details.

Other Financial Instruments

The carrying amounts of our cash, receivables and payables approximate fair value due to the short-term nature of those instruments.

The carrying amount of borrowings outstanding under our Credit Facility approximates fair value due to its variable interest rate. The fair value of these outstanding borrowings is a Level 3 measurement.

The fair value of our fixed rate debt is estimated using yields observable in active markets, which are Level 2 inputs, and was as follows (in thousands):

	June 30, 2020		December 31, 2019

2020 Plan

The 2020 Plan was adopted in April 2020 and provides for the granting of stock options, restricted stock, restricted stock units, stock appreciation rights, performance awards, other stock-based awards and dividend equivalent rights to employees, directors and consultants of Archrock. Under the 2020 Plan, the maximum number of shares of common stock available for issuance is 8,500,000. Each stock-settled award granted under the 2020 Plan reduces the number of shares available for issuance by one share. No additional grants may be made under the 2013 Plan following the adoption of the 2020 Plan. Previous grants made under the 2013 Plan continue to be governed by that plan and the applicable award agreements.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

20. Commitments and Contingencies

Performance Bonds

In the normal course of business we have issued performance bonds to various state authorities that ensure payment of certain obligations. We have also issued a bond to protect our 401(k) retirement plan against losses caused by acts of fraud or dishonesty. The bonds have expiration dates in 2020 through the fourth quarter of 2022 and maximum potential future payments of $2.2 million. As of June 30, 2020, we were in compliance with all obligations to which the performance bonds pertain.

Tax Matters

We are subject to a number of state and local taxes that are not income-based. As many of these taxes are subject to audit by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount of the liability. As of June 30, 2020 and December 31, 2019, we accrued $2.6 million and $2.5 million, respectively, for the outcomes of non-income-based tax audits. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We believe the likelihood is remote that the impact of potential unasserted claims from non-income-based tax audits could be material to our consolidated financial position, but it is possible that the resolution of future audits could be material to our consolidated results of operations or cash flows.

Subject to the provisions of the tax matters agreement between Exterran Corporation and us, both parties agreed to indemnify the primary obligor of any return for tax periods beginning before and ending before or after the Spin-off (including any ongoing or future amendments and audits for these returns) for the portion of the tax liability (including interest and penalties) that relates to their respective operations reported in the filing. The tax contingencies mentioned above relate to tax matters for which we are responsible in managing the audit. As of June 30, 2020 and December 31, 2019, we had an indemnification liability (including penalties and interest), in addition to the tax contingency above, of $1.6 million and $2.8 million, respectively, for our share of non-income-based tax contingencies related to audits being managed by Exterran Corporation.

Insurance Matters

Our business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of natural gas or well fluids and fires or explosions. As is customary in our industry, we review our safety equipment and procedures and carry insurance against some, but not all, risks of our business. Our insurance coverage includes property damage, general liability and commercial automobile liability and other coverage we believe is appropriate. We believe that our insurance coverage is customary for the industry and adequate for our business; however, losses and liabilities not covered by insurance would increase our costs.

Additionally, we are substantially self-insured for workers’ compensation and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to the deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. We are also self-insured for property damage to our offshore assets.

Litigation and Claims

In the ordinary course of business, we are involved in various pending or threatened legal actions. While we are unable to predict the ultimate outcome of these actions, we believe that any ultimate liability arising from any of these actions will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to pay dividends. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our consolidated financial position, results of operations or cash flows, including our ability to pay dividends.

In connection with the closing of the Elite Acquisition, we issued 21.7 million shares of our common stock to JDH Capital, an affiliate of our customer Hilcorp. As long as JDH Capital, together with affiliates of Hilcorp, owns at least 7.5% of our outstanding common stock, it will have the right to designate one director to our Board of Directors. In August 2019, Jeffery D. Hildebrand, founder and executive chairman of Hilcorp, was elected to our Board of Directors. Mr. Hildebrand receives no compensation for his role as a director. As of June 30, 2020, JDH Capital owned 14.2% of our outstanding common stock.

Revenue from Hilcorp and affiliates was $10.2 million and $4.9 million during the three months ended June 30, 2020 and 2019, respectively, and $20.8 million and $10.4 million during the six months ended June 30, 2020 and 2019, respectively. Accounts receivable, net due from Hilcorp and affiliates was $4.0 million and $5.1 million as of June 30, 2020 and December 31, 2019, respectively.

Segments

22. Segments

We manage our business segments primarily based on the type of product or service provided. We have two segments which we operate within the U.S.: contract operations and aftermarket services. The contract operations segment primarily provides natural gas compression services to meet specific customer requirements. The aftermarket services segment provides a full range of services to support the compression needs of customers, from parts sales and normal maintenance services to full operation of a customer’s owned assets.

We evaluate the performance of our segments based on gross margin for each segment. Revenue includes only sales to external customers.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Credit Losses

Credit Losses

In June 2016, the FASB issued ASU 2016-13, which changes the impairment model for financial assets measured at amortized cost and certain other instruments, and requires entities to use a new current expected credit loss model that results in recognition of expected losses over the contractual life of an asset. We adopted ASU 2016-13 on January 1, 2020 using the modified retrospective approach. The adoption resulted in a $0.2 million decrease in our allowance for credit losses and a corresponding pre-tax cumulative effect adjustment to retained earnings in our condensed consolidated balance sheet at January 1, 2020. Comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods.

Our financial assets measured at amortized cost consist of cash equivalents and trade receivables from revenue transactions within the scope of ASC 606 Revenue. We believe our temporary cash investments have a zero loss expectation because we maintain minimal balances in our cash investment accounts and have no history of loss. Trade accounts receivable are due from companies of varying size engaged principally in oil and natural gas activities throughout the U.S. We review the financial condition of customers prior to extending credit and generally do not obtain collateral for trade receivables. Payment terms are on a short-term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ financial resources, the nature of the products and services we provide and the terms of our customer agreements.

Due to the short-term nature of our trade receivables, we consider the amortized cost to be the same as the carrying amount of the receivable, excluding the allowance for credit losses. We recognize an allowance for credit losses when a receivable is recorded, even when the risk of loss is remote. We utilize an aging schedule to determine our allowance for credit losses, and measure expected credit losses on a collective (pool) basis when similar risk characteristics exist. We rely primarily on ratings assigned by external rating agencies and credit monitoring services to assess credit risk and aggregate customers first by low, medium or high risk asset pools, and then by delinquency status. We also consider the internal risk associated with geographic location and the services we provide to the customer when determining asset pools. If a customer does not share similar risk characteristics with other customers, we evaluate the customer’s outstanding trade receivables for expected credit losses on an individual basis. Trade receivables evaluated individually are not included in our collective assessment. Each reporting period, we reassess our customers’ risk profiles and determine the appropriate asset pool classification, or perform individual assessments of expected credit losses, based on the customers’ risk characteristics at the reporting date.

The contractual life of our trade receivables is primarily 30 days based on the payment terms specified in the contract. Contract operations services are generally billed monthly at the beginning of the month in which service is being provided. Aftermarket services billings typically occur when parts are delivered or service is completed. Loss rates are separately determined for each asset pool based on the length of time a trade receivable has been outstanding. We analyze two years of internal historical loss data, including the effects of prepayments, write-offs and subsequent recoveries, to determine our historical loss experience. Our historical loss information is a relevant data point for estimating credit losses, as the data closely aligns with trade receivables due from our customers. Ratings assigned by external rating agencies and credit monitoring services consider past performance and forecasts of future economic conditions in assessing credit risk. We routinely update our historical loss data to reflect our customers’ current risk profile, to ensure the historical data and loss rates are relevant to the pool of assets for which we are estimating expected credit losses. Judgement is used to determine the expected credit loss for customers that do not share similar risk characteristics with other customers, based on customer specific items such as legal proceedings, past experience with the customer and/or ongoing customer negotiations.

The following table summarizes the changes in our allowance for credit losses balance during the six months ended June 30, 2020 (in thousands):

Balance at December 31, 2019	$	2,210
Impact of adoption of ASU 2016-13 on January 1, 2020		(216)
Provision for credit losses		2,282
Write-offs charged against allowance		(646)

Fair Value Measurements

Fair Value Measurements

On January 1, 2020, we adopted ASU 2018-13, which amends the required fair value measurements disclosures related to valuation techniques and inputs used, uncertainty in measurement and changes in measurements applied. These amendments resulted in new, prospective disclosures of the range and weighted average of the significant unobservable inputs used to develop our Level 3 fair value measurements related to our idle and previously-culled compressors. The adoption of ASU 2018-13 had no impact on our condensed consolidated financial statements.

Income Taxes

Income Taxes

On January 1, 2020, we adopted ASU 2019-12, which simplifies the accounting for income taxes by, among other things, removing certain exceptions related to the incremental approach for intraperiod tax allocation, the year-to-date loss methodology for calculating income taxes in an interim period and the recognition for deferred tax liabilities on outside basis differences. ASU 2019-12 also clarifies other aspects of the accounting for income taxes in order to improve consistency of application. The adoption of ASU 2019-12 had no impact on our condensed consolidated financial statements.

Accounting Standards Updates Not Yet Implemented

Accounting Standards Updates Not Yet Implemented

Reference Rate Reform

In March 2020, the FASB issued ASU 2020-04, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued as a result of reference rate reform. ASU 2020-04 is effective for all entities as of March 12, 2020 through December 31, 2022. Entities may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020. We are currently assessing the impact that ASU 2020-04 may have on our interest rate swap agreements, Credit Facility and other transactions that may be affected by reference rate reform.
