Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Accounting and Presentation The accompanying consolidated financial statements were prepared on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. Corporate Conversion and Stock Split On October 14, 2020, prior to the issuance of any of our shares of common stock in the IPO, we converted from a Delaware limited liability company to a Delaware corporation. In connection with the corporate conversion we converted all 1,000 of our outstanding member units into 100,000,000 shares of common stock and then completed a stock split of 1.19994-for-1. The corporate conversion and stock split representing 119,994,467 shares of common stock have been adjusted retroactively for the purposes of calculating basic and diluted earnings per share. Principles of Consolidation The consolidated financial statements include the accounts of Array Technologies, Inc. and its Subsidiaries, which include HDF, ATI Investment and Array. All intercompany accounts and transactions have been eliminated upon consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates. Significant estimates include impairment of goodwill, impairment of long-lived assets, fair value of contingent consideration, allowance for doubtful accounts, reserve for excess or obsolete inventories, valuation of deferred tax assets and warranty reserve. Management believes that these estimates and assumptions provide a reasonable basis for the fair presentation of the consolidated financial statements. Impact of COVID-19 Pandemic In December 2019, a novel strain of coronavirus, SARS-CoV-2, which causes coronavirus disease 2019, or COVID-19, surfaced in Wuhan, China. Since then, COVID-19 has spread to multiple countries, including the United States. On March 11, 2020, the World Health Organization declared COVID-19 a pandemic. To date, the Company has maintained uninterrupted business operations with normal turnaround times for its delivery of solar tracking systems. The Company has implemented adjustments to its operations designed to keep employees safe and comply with federal, state and local guidelines, including those regarding social distancing. The extent to which COVID19 may further impact the Company’s business, results of operations, financial condition and cash flows will depend on future developments, which are highly uncertain and cannot be predicted with confidence. In response to COVID-19, the United States government has passed legislation and taken other actions to provide financial relief to companies and other organizations affected by the pandemic. Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. At December 31, 2019, the Company had $51.0 million in restricted cash. The restricted cash secured its standby letter of credit facility which expired August 31, 2020 (see Note 8). As such, the restricted cash is considered a current asset in the accompanying balance sheets. The following table provides a reconciliation of cash, cash equivalents and restricted cash as reported within the consolidated balance sheets to the same such amounts shown in the consolidated statements of cash flows (in thousands): December 31, 2020 2019 Cash and cash equivalents $ 108,441 $ 310,262 Restricted cash — 50,995 Cash and cash equivalents and restricted cash $ 108,441 $ 361,257 Accounts Receivable The Company’s accounts receivable are due primarily from solar contractors across the United States and internationally. Credit is extended in the normal course of business based on evaluation of a customer’s financial condition and, generally, collateral is not required. Trade receivables consist of uncollateralized customer obligations due under normal trade terms requiring payment within 30-60 days of the invoice date. Management regularly reviews outstanding accounts receivable and provides for estimated losses through an allowance for doubtful accounts or direct write-off. In evaluating the level of established reserves, management makes judgments regarding the customers’ ability to make required payments, economic events, and other factors. As the financial conditions of these customers change, circumstances develop, or additional information becomes available, adjustments to the allowance for doubtful accounts may be required. When deemed uncollectible, the receivable is charged against the allowance or directly written off. At December 31, 2020 and 2019, the allowance for doubtful accounts was $0.7 million and $0.2 million, respectively. Amounts retained by project owners under contracts and included in accounts receivable at December 31, 2020 and 2019 were $4.1 million and $6.1 million, respectively. Such retention amounts represent funds withheld by our customers until the products are installed by a third party, arranged by the customer, and the project is declared operational. Retention amounts and length of retention periods may vary. All retention amounts outstanding as of December 31, 2020 are collectible within the next 12 months. Inventories Inventories consist of raw materials and finished goods. Inventories are stated at the lower of cost or estimated net realizable value using the weighted average method. Provisions are made to reduce excess or obsolete inventories to their estimated net realizable values. See Note 3 for a detail of the components that comprise the inventory balance presented on the accompanying consolidated balance sheets. Property, Plant and Equipment Property, plant and equipment acquired in the acquisition of Array are recorded at fair value at the date of acquisition net of accumulated depreciation and amortization; all other property, plant and equipment are recorded at cost, net of accumulated depreciation and amortization. Improvements, betterments and replacements which significantly extend the life of an asset are capitalized. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the respective assets. Repair and maintenance costs are expensed as incurred. A gain or loss on the sale of property, plant and equipment is calculated as the difference between the cost of the asset disposed of, net of depreciation, and the sales proceeds received. A gain or loss on an asset disposal is recognized in the period that the sale occurs. Impairment of Long-Lived Assets When events, circumstances or operating results indicate that the carrying values of long-lived assets might not be recoverable through future operations, the Company prepares projections of the undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the projections indicate that the recorded amounts are not expected to be recoverable, such amounts are reduced to estimated fair value. Fair value is estimated based upon internal evaluation of each asset that includes quantitative analyses of net revenue and cash flows, review of recent sales of similar assets and market responses based upon discussions in connection with offers received from potential buyers. Management determined there was no impairment for the years ended December 31, 2020, 2019 and 2018. Goodwill Goodwill reflects the excess of the consideration transferred, including the fair value of any contingent consideration over the assigned fair values of the identifiable net assets acquired. Goodwill is not amortized, and is assigned to the reporting unit and tested for impairment at least on an annual basis. Goodwill is assessed using either a qualitative assessment or quantitative approach to determine whether it is more likely than not that the fair value of the reporting unit is less than the carrying amount. The qualitative assessment evaluates factors including macroeconomic conditions, industry-specific and company-specific considerations, legal and regulatory environments, and historical performance. If the Company determines that is more likely than not that the fair value of a reporting unit is less than its carrying value, a quantitative assessment is performed. Otherwise, no further assessment is required. The quantitative approach compares the estimated fair value of the reporting unit to its carrying amount, including goodwill. Impairment is indicated if the estimated fair value or the reporting unit is less than the carrying amount of the reporting unit, and an impairment charge is recognized for the differential. The Company completes its annual goodwill impairment test as of year-end. At December 31, 2020, the Company performed a qualitative assessment of its goodwill. At December 31, 2019 and 2018, the Company performed a quantitative assessment of its goodwill. For the years ended December 31, 2020, 2019 and 2018 no goodwill impairment was recorded by the Company. Amortizable and Other Intangible Assets The Company amortizes identifiable intangible assets consisting of developed technology, customer relationships, contractual backlog and internal-use software modifications because these assets have finite lives. The Company’s intangible assets with finite lives are amortized on a straight-line basis over the estimated useful lives. The basis of amortization approximates the pattern in which the assets are utilized, over their estimated useful lives. The Array Technologies trade name has been determined to have an indefinite life and, therefore, is not amortized but is subject to an annual impairment test or at any other time when impairment indicators exist. The Company completed its annual impairment test for its non-amortizable asset (Trade Name) by comparing the estimated fair value to the carrying value of such asset. Based on the results of the tests, the Company did not recognize any impairment charges for the years ended December 31, 2020, 2019 and 2018. Deferred Offering Costs Deferred offering costs consist primarily of registration fees, filing fees, listing fees, specific legal and accounting costs, and transfer agent fees, which are direct and incremental fees related to the IPO. Deferred offering costs were offset against the IPO proceeds. Debt Discount and Financing Costs Debt discount and financing costs incurred to issue debt are deferred and amortized using the effective interest method as a component of interest expense over the life of the related debt agreement. Amortization expense of debt discount and deferred financing costs was $3.4 million, $4.0 million and $3.0 million, respectively, for the years ended December 31, 2020, 2019 and 2018. Revenue Recognition 2020 and 2019 The Company recognized revenues from the sale of solar tracking systems and parts and determines its revenue recognition through the following steps (i) identification of the contract or contracts with a customer, (ii) identification of the performance obligations within the contract, (iii) determination of the transaction price, (iv) allocation of the transaction price to the performance obligations within the contract, and (v) recognition of revenue when, or as the performance obligation has been satisfied. Performance Obligations The Company’s contracts with customers are predominately accounted for as one performance obligation, as the majority of tasks and services is part of a single project or capability. As these contracts are typically a customized assembly for a customer-specific solution, the Company uses the expected cost-plus margin approach to estimate the standalone selling price of each performance obligation. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract. In assessing the recognition of revenue, the Company also evaluates whether two or more contracts should be combined and accounted for as one contract and if the combined or single contract should be accounted for as multiple performance obligations which could change the amount of revenue and profit (loss) recorded in a period. Change orders may include changes in specifications or design, manner of performance, equipment, materials, scope of work, and/or the period of completion of the project. The Company analyzes its change orders to determine if they should be accounted for as a modification to an existing contract or a new stand-alone contract. The Company’s change orders are generally modifications to existing contracts and are included in the total estimated contract revenue when it is probable that the change order will result in additional value that can be reliably estimated and realized. The majority of the Company’s contracts do not contain variable consideration provisions as a continuation of the original contract. The Company’s performance obligations are satisfied predominately over-time as work progresses for its custom assembled solar systems, utilizing an output measure of completed products and based on the timing of the product’s shipments considering the shipping terms described in the contract. In certain situations, when product is still in our custody, and title and risk of loss has passed to the customer (known as bill-and-hold arrangement), revenue will be recognized when all the specific requirements for transfer of control under a bill-and-hold arrangement have been met. Revenue recognized for the Company’s part sales are recorded at a point in time and recognized when obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is in line with shipping terms. Contract Estimates Accounting for contracts utilizing the over-time method and their expected cost-plus margins is based on various assumptions to project the outcome of future events that can exceed a year. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; and the availability and timing of funding from the customer. The Company reviews and updates its contract-related estimates each reporting period. The Company recognizes adjustments in estimated expected cost-plus on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the total loss in the period it is identified. Contract Balances The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and deferred revenue (contract liabilities) on the consolidated balance sheets. The majority of the Company’s contract amounts are billed as work progresses in accordance with agreed-upon contractual terms, which generally coincide with the shipment of one or more phases of the project. Billing sometimes occurs subsequent to revenue recognition, resulting in contract assets. The changes in contract assets (i.e. unbilled receivables) and the corresponding amounts recorded in revenue relate to fluctuations in the timing and volume of billings for the Company’s revenue recognized over-time. As of December 31, 2020 and December 31, 2019, contract assets consisting of unbilled receivables totaling $18.1 million and $16.1 million, respectively, are included within accounts receivable on the consolidated balance sheets on a contract-by-contract basis at the end of the reporting period. The Company also receives advances or deposits from its customers, before revenue is recognized, resulting in contract liabilities. The changes in contract liabilities (i.e. deferred revenue) relate to advanced orders and payments received by the Company and are the result of customers looking to take advantage of certain U.S. federal tax incentives set to decrease at the end of 2019. Based on the terms of the tax incentives the customer must pay for the goods prior to December 31, 2019 which accounts for the increase in the advanced orders and payments and the resulting deferred revenue at December 31, 2019 and subsequent reduction for deliveries which occurred during the year ended December 31, 2020. As of December 31, 2020 and December 31, 2019, contract liabilities consisting of deferred revenue were $149.8 million and $328.8 million, respectively and were recorded on a contract-by-contract basis at the end of each reporting period. During the years ended December 31, 2020 and 2019, the Company converted $328.8 million and $21.8 million deferred revenue to revenue, respectively, which represented 100% of the prior years deferred revenue balance. Remaining Performance Obligations As of December 31, 2020, the Company had $455.3 million of remaining performance obligations. The Company expects to recognize revenue on 100% of these performance obligations in the next twelve months. Revenue Recognition - 2018 Products are sold by the Company for cash-in-advance and on credit. Revenue is recognized when persuasive evidence of an agreement exists and upon delivery and acceptance, or earlier if required by shipping terms, provided title is transferred, prices are fixed or determinable, and collection is deemed probable. Revenues are presented net of sales, use, value-added and other excise taxes collected by the Company that are remitted to various governmental authorities. Warranty Obligations The Company offers an assurance type warranty for its products against defects in design, materials and workmanship for a period ranging from two Income Taxes The Company provides for income taxes based on the provisions of FASB ASC Topic 740, Income Taxes, which, among other things, requires that recognition of deferred income taxes be measured by the provisions of enacted tax rates in effect at the date of the consolidated financial statements. A valuation allowance is provided to reduce deferred income tax assets if it is more likely than not that all, or some portion, of such deferred tax assets will not be recognized. Provision for estimated income taxes is based upon elements of income and expense reported in the consolidated statements of operations. The Company also files certain corporate state income tax returns. Generally, the Company is subject to examination by U.S. federal (or state or local) income tax authorities for three years from the filing of a tax return. The current provision for income taxes represents actual or estimated amounts payable on tax return filings each year. Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, and for operating loss and tax credit carryforwards. The change in deferred tax assets and liabilities for the period measures the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws on deferred tax assets and liabilities are reflected as adjustments to the tax provision or benefit in the period of enactment. Adjustments for penalties and interest, if any, are also reflected in the current year tax provision or benefit. The Company determines whether uncertain tax positions are more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The Company recognizes interest and penalties related to unrecognized tax benefits within the interest expense line and other expense line, respectively, in the consolidated statements of operations. Accrued interest and penalties are included within the related liability lines in the consolidated balance sheets. Equity-Based Compensation The Company recognizes equity-based compensation expense based on the equity award’s grant date fair value. The determination of the fair value of equity awards issued to employees of the Company is based upon the underlying share price and a number of assumptions, including volatility, performance period, risk-free interest rate and expected dividends. The Company accounts for forfeitures as they occur. The grant date fair value of each unit is amortized on a straight-line basis over the requisite service period. Earnings per Share (“EPS”) Basic earnings per share, or EPS, is computed by dividing net income available to shareholders by the weighted average shares outstanding during the period. Diluted EPS takes into account the potential dilution that could occur if securities or other contracts to issue shares, such as stock options and unvested restricted stock, were exercised and converted into shares. Diluted EPS is computed by dividing net income available to shareholders by the weighted average shares outstanding during the period, increased by the number of additional shares that would have been outstanding if the potential shares had been issued and were dilutive. CARES Act Payroll Tax Deferral The CARES Act permits employers to defer the payment of the employer share of social security taxes due for the period beginning March 27, 2020 and ending December 31, 2020. Of the amounts deferred, 50% are required to be paid by December 31, 2021 and the remaining 50% are required to be paid by December 31, 2022. The Company began deferring payment of the employer share of social security taxes in April 2020. As of December 31, 2020, the Company had deferred payment of $1.0 million of such taxes. Credit Concentration Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, restricted cash and accounts receivable. The Company has no significant off balance sheet concentrations of credit risk. The Company maintains its cash and restricted cash with financial institutions that are believed to be of high credit quality and has not experienced any material losses relating to any cash and restricted cash. As of December 31, 2020 and December 31, 2019, $108.2 million and $360.9 million, respectively, of the Company’s bank balances were uninsured and uncollateralized and exposed to custodial credit risk. The Company’s customer base consists primarily of solar contractors and utilities. The Company does not require collateral on its trade receivables. For the year ended December 31, 2020, the Company’s largest customer and five largest customers constituted 11.2% and 40.9% of total revenues, respectively. Two customers made up 21.5% of revenue and are the only customers greater than 10% of total revenue for the year ended December 31, 2020. For the year ended December 31, 2019, the Company’s largest customer and five largest customers constituted 17.2% and 50.1% of total revenues, respectively. Two customers made up 28.7% of revenue and are the only customers constituting greater than 10% of total revenue for the year ended December 31, 2019. For the year ended December 31, 2018, the Company’s largest customer and five largest customers constituted 17.5% and 50.9% of total revenues, respectively. Two customers make up 28.3% of revenue and are the only customers constituting greater than 10% of total revenue. The loss of any one of the Company’s top five customers could have a materially adverse effect on the revenues and profits of the Company. Further, the Company’s trade accounts receivable are from companies within the solar industry and, as such, the Company is exposed to normal industry credit risks. As of December 31, 2020, the Company’s largest customer and five largest customers constituted 0.1% and 20.9% of trade accounts receivable, respectively. As of December 31, 2019, the Company’s largest customer and five largest customers constituted 29.5% and 69.0% of trade accounts receivable, respectively. The Company continually evaluates its reserves for potential credit losses and establishes reserves for such losses. Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company follows a fair value hierarchy which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Three levels of inputs may be used to measure fair value, as follows: • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity that are significant to the fair value of the assets or liabilities. Assets valued using Level 1 inputs are determined by quoted market prices derived from an active market and Level 2 inputs are based primarily on quoted prices for similar assets in active or inactive markets. Level 3 inputs are valued by management’s assumptions about the assumptions the market participants would utilize in pricing the asset. The fair values of the Company’s cash, restricted cash, accounts receivable, and accounts payable approximate their carrying values due to their short maturities. The carrying value of the Company’s notes payable and related party loans approximates their fair values, as they are based on current market rates at which the Company could borrow funds with similar terms. The Company follows the provisions of FASB ASC Topic 820-10 for nonfinancial assets and liabilities measured at fair value on a non-recurring basis. As it relates to the Company, this applies to certain nonfinancial assets and liabilities acquired in business combinations and measurement of goodwill impairment and non-amortizable intangibles and is thereby measured at fair value. The Company has determined such fair value primarily by third-party valuations. New Accounting Standards To be adopted In February 2016, the FASB issued ASU No. 2016-02 (Topic 842) “Leases” which supersedes the lease recognition requirements in ASC Topic 840, “Leases” . Under ASU No. 2016-02, lessees are required to recognize assets and liabilities on the consolidated balance sheets for most leases and provide enhanced disclosures. Leases will continue to be classified as either finance or operating. For companies that are not emerging growth companies (“EGCs”), the ASU is effective for fiscal years beginning after December 15, 2018. For EGCs, the ASU is effective for fiscal years beginning after December 15, 2021. The Company plans to adopt the new standard using the modified retrospective method, under which the Company will apply Topic 842 to existing and new leases as of the effective date of January 1, 2021, but prior periods will not be restated and will continue to be reported under Topic 840 guidance in effect during those periods. The Company anticipates that the adoption will not have a material impact on its consolidated statements of operations or its consolidated statements of cash flows but expects to recognize right-of-use assets and liabilities for lease obligations associated with its operating leases. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses , which was subsequently amended by ASU No. 2018-19 and ASU No. 2019-10, requires the measurement of expected credit losses for financial instruments carried at amortized cost held at the reporting date based on historical experience, current conditions and reasonable forecasts. The updated guidance also amends the current other-than-temporary impairment model for available-for-sale debt securities by requiring the recognition of impairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. In addition, the length of time a security has been in an unrealized loss position will no longer impact the determination of whether a credit loss exists. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The standard is effective for the fiscal year beginning after December 15, 2022, or December 15, 2021 if we were to lose EGC’s status in 2021. The Company will continue to assess the possible impact of this standard, but currently does not expect the adoption of this standard will have a significant impact on its consolidated financial statements and its limited history of bad debt expense relating to trade accounts receivable. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU No. 2019-12”), which is intended to simplify various aspects of the accounting for income taxes. ASU No. 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This standard is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures. Adopted In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement

The Company is no longer subject to U.S. federal and state income tax examinations by tax authorities for years before 2014. As of December 31, 2020, the Company had no federal income tax net operating loss (“NOL”) carryforwards. The Company has state income tax NOL carryforwards of approximately $7.6 million that will expire in future years beginning in 2036. Realization of deferred tax assets associated with net operating loss carryforwards is dependent upon generating sufficient taxable income in the appropriate jurisdictions prior to their expirations, if any expiration. The existence of reversing temporary differences supports the recognition by the Company of certain deferred tax assets. It is not more likely than not that those deferred tax assets from certain state net operating loss carryforwards would be realized due to the Company’s lack of earnings history and as such the Company established a valuation allowance of $208 thousand for the years ended years ended December 31, 2020 and 2019. ASC 740, Income Taxes, addresses the determination of how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. In accordance with ASC 740, the Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. The Company’s assessments of its tax positions in accordance with ASC 740 did not result in changes that had a material impact on results of operations, financial condition or liquidity. The Company had no unrecognized income tax benefits at either December 31, 2020 or 2019. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was enacted in response to the COVID-19 pandemic. Among other things, the CARES Act provided the ability for taxpayers to carryback a net operating loss (“NOL”) arising in a taxable year beginning after December 31, 2017 and before January 1, 2021 to each of the five years preceding the year of the loss. The Company generated a significant NOL during its tax year ended March 31, 2019 and filed a carryback claim in June 2020 for this NOL. As a result of the carryback claim, the Company recorded an income tax benefit of $6.6 million on its consolidated statement of operations for the year ended December 31, 2020, resulting from the difference in the current U.S. federal tax rate of 21% and the tax rate of 35% applicable in the carryback year. The Company’s 2017 federal income tax return was selected for examination by the IRS in 2018. As a result of the examination, an adjustment related to the value allocated to the developed technology for tax purposes was potentially required. During 2019, the Company settled the 2017 examination and agreed to a reduction in the developed technology value from $210 million to $188 million for federal income tax purposes. As a result of this change in the value of the acquired developed technology, the Company reduced its NOL carryforwards by approximately $2.8 million for previously taken amortization and increased the deferred tax liability related to the revised developed technology tax basis by approximately $4.6 million. In addition, the Company will no longer receive tax basis upon payment of the Tax Receivable Agreement (“TRA”) liability, as such the related deferred tax asset of $4.7 million for the TRA was also written off during 2019. The adjustments resulting from the change in developed technology value have been recorded as an income tax expense for the year ended December 31, 2019. Refer to Note 13 - Commitments and Contingencies, for detail on the TRA, which was contingent consideration at the time of the Array acquisition.

Guarantees and Security The obligations under the Senior Secured Credit Facility are guaranteed by ATI Investment Sub, Inc. and its wholly owned domestic subsidiaries other than certain immaterial subsidiaries and other excluded subsidiaries. The obligations under the Senior Secured Credit Facility are secured by a first priority security interest in substantially all of Array Tech, Inc.’s and the guarantors’ existing and future property and assets, including accounts receivable, inventory, equipment, general intangibles, intellectual property, investment property, other personal property, material owned real property, cash and proceeds of the foregoing. Prepayments and Amortization Loans under the Revolving Credit Facility may be voluntarily prepaid in whole, or in part, in each case without premium or penalty. Loans under the Term Loan Facility may be voluntarily prepaid in whole, or in part, in each case without premium or penalty (other than a 1% premium with respect to prepayments on account of certain “repricing events,” subject to exceptions, occurring within 12 months of the closing date of the Senior Secured Credit Facility). The Senior Secured Credit Facility requires mandatory prepayments, but not permanent reductions of commitments thereunder, for excess cash flow, asset sales, subject to a right of reinvestment, and refinancing facilities. The Term Loan Facility amortizes in equal quarterly installments in aggregate annual amounts equal to 1.00% per annum of the original principal amount of the loans funded thereunder. There is no scheduled amortization under the Revolving Credit Facility. Restrictive Covenants and Other Matters The Senior Secured Credit Facility contains affirmative and negative covenants including covenants that restrict our incurrence of indebtedness, incurrence of liens, dispositions, investments, acquisitions, restricted payments, transactions with affiliates, as well as other negative covenants customary for financings of this type. The Revolving Credit Facility also includes a springing financial maintenance covenant that is tested on the last day of each fiscal quarter if the outstanding loans and certain other credit extensions under the Revolving Credit Facility exceed 35% of the aggregate amount of commitments thereunder, subject to customary exclusions and conditions. If the financial maintenance covenant is triggered, the first lien net leverage ratio will be tested for compliance not to exceed 7.10 to 1.00. The Senior Secured Credit Facility also includes customary events of default, including the occurrence of a change of control. As of December 31, 2020, the Company was in compliance with all the required covenants. Term Loan Credit and Guarantee Agreement The Company had a Term Loan Credit and Guarantee Agreement (the “Term Loan”) as amended. The Term Loan was secured by assets of ATI Investment. The Term Loan was payable in quarterly installments of $5 million. As of December 31, 2019, the Term Loan had a balance of $57.7 million. The Term Loan accrued interest equal to applicable margin of 6.25% plus base rate (8.96% at December 31, 2019). The balance of the Term loan is presented in the accompanying consolidated balance sheets net of debt discount and financing costs of $1.8 million at December 31, 2019. The Term Loan had an annual excess cash flow calculation which could require the Company to make advance principal payments. At December 31, 2019, the excess cash flow calculation resulted in the Term Loan be classified as current on the accompanying consolidated balance sheet. The Company paid the outstanding amount due on the Term Loan on February 2, 2020 and settled all obligations with respect to the Term Loan. Revolving Loan The Company had a credit facility (the “Revolving Loan”) as amended, which had a commitment of $100.0 million as of December 31, 2019. As of December 31, 2019, the Revolving Loan had an outstanding balance of $70 thousand. The Company paid the outstanding amount due on the Revolving Loan on October 14, 2020 and settled all obligations with respect to the Revolving Loan. Letter of Credit Facility On December 16, 2019, the Company entered into a letter of credit facility (“LC Facility”) to provide customers with additional credit support in the form of a standby letter of credit to secure the Company’s performance obligations under contracts for which certain customers elected to prepay for the design and manufacture of solar projects. The LC Facility had a commitment of $100.0 million in standby letters of credit and expired August 31, 2020. At December 31, 2019, the Company had $51.0 million in outstanding standby letters of credit outstanding, secured by cash collateral.

Commitments and Contingencies	Commitments and Contingencies Operating Leases Future minimum lease payments under non-cancellable operating leases as of December 31, 2020 are as follows (in thousands): For the Year Ending December 31, 2021 $ 6,663 2022 6,073 2023 893 2024 791 2025 15 Thereafter — $ 14,435 For the year ended December 31, 2020, the Company recorded lease expenses associated with its operating leases in cost of revenues and general and administrative within its consolidated statements of operations totaling $7.0 million and $0.4 million, respectively. For the year ended December 31, 2019, the Company recorded lease expenses associated with its operating leases in cost of revenues and general and administrative within its consolidated statements of operations totaling $1.5 million and $0.3 million, respectively. Litigation The Company, in the normal course of business, is subject to claims and litigation. Management believes that there are no outstanding claims or assessments against the Company that would result in a material unfavorable outcome. Contingent Consideration TRA Concurrent with Former Parent’s acquisition of Array Technologies Patent Holdings Co., LLC (the “Patent LLC”), Array Tech, Inc. (f/k/a Array Technologies, Inc.) entered into a TRA with the former majority shareholder of Array. The TRA is valued based on the future expected payments under the agreement. The TRA provides for the payment by Array Tech, Inc. (f/k/a Array Technologies, Inc.) to the former owners for certain federal, state, local and non-U.S. tax benefits deemed realized in post-closing taxable periods by Array, from the use of certain deductions generated by the increase in the tax value of the developed technology. The TRA is accounted for as contingent consideration and subsequent changes in fair value of the contingent liability are included in general and administrative in the accompanying consolidated statements of operations. At December 31, 2020 and December 31, 2019, the fair value of the TRA was $19.7 million and $17.8 million, respectively. Estimating the amount of payments that may be made under the TRA is by nature imprecise. The significant fair value inputs used to estimate the future expected TRA payments to the former owners include the timing of tax payments, a discount rate, book income projections, timing of expected adjustments to calculate taxable income and the projected rate of use for attributes defined in the TRA. Payments made under the TRA consider tax positions taken by the Company and are due within 125 days following the filing of the Company’s U.S. federal and state income tax returns under procedures described in the agreement. The current portion of the TRA liability is based on tax returns. The TRA will continue until all tax benefit payments have been made or the Company elects early termination under the terms described in the TRA. As of December 31, 2020, the undiscounted future expected payments through December 31, under the TRA are as follows (in thousands): Amount 2021 $ 9,113 2022 1,748 2023 1,748 2024 1,748 2025 1,749 Thereafter 9,186 $ 25,292 Earn-Out Liability The Company is required to pay the selling stockholders of Array future contingent consideration consisting of earn-out payments in the form of cash upon the occurrence of certain events, including the sale, transfer, assignment, pledge, encumbrance, distribution or disposition of shares held by the acquirer to a third party; initial public offering of the equity securities of Former Parent, acquirer or the Company; the sale of equity securities or assets of Former Parent, acquirer or the Company to a third-party; or a merger, consolidation, recapitalization or reorganization of Former Parent, acquirer or the Company. The maximum aggregate earn-out consideration was $25.0 million. The fair value of the earn-out liability was initially determined as of the acquisition date using unobservable inputs. These inputs include the estimated amount and timing of future cash flows, the probability of a qualifying event occurring, and a risk-free rate used to adjust the probability-weighted cash flows to their present value. Subsequent to the acquisition date, at each reporting period, the earn-out liability is re-measured to fair value with changes in fair value included in general and administrative in the accompanying consolidated statements of operations. On October 14, 2020 and December 7, 2020, as a result of certain qualifying events, the Special Distribution (see Note 15 - Related Party Transactions) shares sold in the IPO and follow on offering by the Former Parent, a payment of $9.1 million and $15.9 million was made to holders of the earn-out. As a result of the payments there are no further obligations related to the Earn-out. The following table summarizes the liability related to the estimated contingent consideration (in thousands): TRA Earn-Out Liability Contingent Consideration Balance, December 31, 2017 $ 17,993 $ 442 $ 18,435 Fair value adjustment (825) — (825) Balance, December 31, 2018 17,168 442 17,610 IRS Settlement (2,727) — (2,727) Fair value adjustment 3,367 — 3,367 Balance, December 31, 2019 17,808 442 18,250 Fair value adjustment 1,883 24,558 26,441 Payments — (25,000) (25,000) Balance, December 31, 2020 $ 19,691 $ — $ 19,691 The TRA and earn-out liabilities require significant judgment and are classified as Level 3 in the fair value hierarchy. Surety Bond The Company provides surety bonds to various parties as required for certain transactions initiated during the ordinary course of business to guarantee the Company’s performance in accordance with contractual or legal obligations. As of December 31, 2020, the maximum potential payment obligation with regard to surety bonds was $121.2 million.

Equity Based Compensation	Dec. 31, 2020
Share-based Payment Arrangement [Abstract]
Equity Based Compensation	Equity-Based Compensation Class B Units and Class C Units of Former Parent The Company accounts for equity grants to employees (Class B units and Class C units, “the Units”, of Former Parent) as equity-based compensation under ASC 718, Compensation-Stock Compensation . The Units contain vesting provisions as defined in the agreement. Vested units do not forfeit upon termination and represent a residual interest in Former Parent. Equity-based compensation cost is measured at the grant date fair value and is recognized on a straight-line basis over the requisite service period, including those units with graded vesting with a corresponding credit to additional paid-in capital as a capital contribution from Former Parent. However, the amount of equity-based compensation at any date is equal to the portion of the grant date value of the award that is vested. The Units issued to employees are measured at fair value on the grant date using an option pricing model. The Company utilizes the estimated weighted average of the Company’s expected fund life dependent on various exit scenarios to estimate the expected term of the awards. Expected volatility is based on the average of historical and implied volatility of a set of comparable companies, adjusted for size and leverage. The risk-free rates are based on the yields of U.S. Treasury instruments with comparable terms. Actual results may vary depending on the assumptions applied within the model. On November 19, 2019 and May 19, 2020, Former Parent issued 22,326,653 and 4,344,941, respectively, Class B units to certain employees of the Company. On March 28, 2020, Former Parent issued 1,000 Class C units to a member of the board of directors of Array Technologies, Inc. 2020 Plan On October 14, 2020, the Company’s 2020 Equity Incentive Plan (the “2020 Plan”) became effective. The 2020 Plan authorized 6,683,919 new shares, subject to adjustments pursuant to the 2020 Plan. Effective October 14, 2020, the Company granted an aggregate of 29,398 restricted stock units (RSU’s) to its non-employee directors in connection with their service on the board of directors and 470,608 RSU’s to certain executives and members of management. The RSU’s were granted under the 2020 Plan at the IPO price of $22.00 per share. Each share has a vesting commencement date of and is subject to a two Activity under the 2020 Plan was as follows: Number of Shares Weighted Average Grant Date Fair Value Unvested, December 31, 2019 — $ — Granted 500,006 22.00 Vested — — Forfeited — — Unvested, December 31, 2020 500,006 $ 22.00 For the year ended December 31, 2020 and 2019, the Company recognized $4.8 million and $0.8 million, respectively, in equity-based compensation. At December 31, 2020, the Company had $17.0 million of unrecognized compensation costs related to Class B units and RSU’s which is expected to be recognized over approximately 3 years. There were no forfeitures during 2020 or 2019.

Reclassifications	Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation.
Corporate Conversion and Stock Split	Corporate Conversion and Stock Split On October 14, 2020, prior to the issuance of any of our shares of common stock in the IPO, we converted from a Delaware limited liability company to a Delaware corporation. In connection with the corporate conversion we converted all 1,000 of our outstanding member units into 100,000,000 shares of common stock and then completed a stock split of 1.19994-for-1. The corporate conversion and stock split representing 119,994,467 shares of common stock have been adjusted retroactively for the purposes of calculating basic and diluted earnings per share.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of Array Technologies, Inc. and its Subsidiaries, which include HDF, ATI Investment and Array. All intercompany accounts and transactions have been eliminated upon consolidation.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ materially from those estimates. Significant estimates include impairment of goodwill, impairment of long-lived assets, fair value of contingent consideration, allowance for doubtful accounts, reserve for excess or obsolete inventories, valuation of deferred tax assets and warranty reserve. Management believes that these estimates and assumptions provide a reasonable basis for the fair presentation of the consolidated financial statements.
Impact of COVID-19 Pandemic and CARES Act Payroll Tax Deferral	Impact of COVID-19 Pandemic In December 2019, a novel strain of coronavirus, SARS-CoV-2, which causes coronavirus disease 2019, or COVID-19, surfaced in Wuhan, China. Since then, COVID-19 has spread to multiple countries, including the United States. On March 11, 2020, the World Health Organization declared COVID-19 a pandemic. To date, the Company has maintained uninterrupted business operations with normal turnaround times for its delivery of solar tracking systems. The Company has implemented adjustments to its operations designed to keep employees safe and comply with federal, state and local guidelines, including those regarding social distancing. The extent to which COVID19 may further impact the Company’s business, results of operations, financial condition and cash flows will depend on future developments, which are highly uncertain and cannot be predicted with confidence. In response to COVID-19, the United States government has passed legislation and taken other actions to provide financial relief to companies and other organizations affected by the pandemic.CARES Act Payroll Tax Deferral The CARES Act permits employers to defer the payment of the employer share of social security taxes due for the period beginning March 27, 2020 and ending December 31, 2020. Of the amounts deferred, 50% are required to be paid by December 31, 2021 and the remaining 50% are required to be paid by December 31, 2022.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.
Accounts Receivable	Accounts Receivable The Company’s accounts receivable are due primarily from solar contractors across the United States and internationally. Credit is extended in the normal course of business based on evaluation of a customer’s financial condition and, generally, collateral is not required. Trade receivables consist of uncollateralized customer obligations due under normal trade terms requiring payment within 30-60 days of the invoice date. Management regularly reviews outstanding accounts receivable and provides for estimated losses through an allowance for doubtful accounts or direct write-off. In evaluating the level of established reserves, management
Inventories	InventoriesInventories consist of raw materials and finished goods. Inventories are stated at the lower of cost or estimated net realizable value using the weighted average method. Provisions are made to reduce excess or obsolete inventories to their estimated net realizable values.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment acquired in the acquisition of Array are recorded at fair value at the date of acquisition net of accumulated depreciation and amortization; all other property, plant and equipment are recorded at cost, net of accumulated depreciation and amortization. Improvements, betterments and replacements which significantly extend the life of an asset are capitalized. Depreciation and amortization is computed using the straight-line method over the estimated useful lives of the respective assets. Repair and maintenance costs are expensed as incurred.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets When events, circumstances or operating results indicate that the carrying values of long-lived assets might not be recoverable through future operations, the Company prepares projections of the undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the projections indicate that the recorded amounts are not expected to be recoverable, such amounts are reduced to estimated fair value. Fair value is estimated based upon internal evaluation of each asset that includes quantitative analyses of net revenue and cash flows, review of recent sales of similar assets and market responses based upon discussions in connection with offers received from potential buyers.
Indefinite-Lived Intangible Assets	The Array Technologies trade name has been determined to have an indefinite life and, therefore, is not amortized but is subject to an annual impairment test or at any other time when impairment indicators exist. The Company completed its annual impairment test for its non-amortizable asset (Trade Name) by comparing the estimated fair value to the carrying value of such asset.
Goodwill	Goodwill Goodwill reflects the excess of the consideration transferred, including the fair value of any contingent consideration over the assigned fair values of the identifiable net assets acquired. Goodwill is not amortized, and is assigned to the reporting unit and tested for impairment at least on an annual basis. Goodwill is assessed using either a qualitative assessment or quantitative approach to determine whether it is more likely than not that the fair value of the reporting unit is less than the carrying amount. The qualitative assessment evaluates factors including macroeconomic conditions, industry-specific and company-specific considerations,
Amortizable and Other Intangible Assets	Amortizable and Other Intangible Assets The Company amortizes identifiable intangible assets consisting of developed technology, customer relationships, contractual backlog and internal-use software modifications because these assets have finite lives. The Company’s intangible assets with finite lives are amortized on a straight-line basis over the estimated useful lives. The basis of amortization approximates the pattern in which the assets are utilized, over their estimated useful lives.
Deferred Offering Costs	Deferred Offering Costs Deferred offering costs consist primarily of registration fees, filing fees, listing fees, specific legal and accounting costs, and transfer agent fees, which are direct and incremental fees related to the IPO. Deferred offering costs were offset against the IPO proceeds.
Debt Discount and Financing Costs	Debt Discount and Financing CostsDebt discount and financing costs incurred to issue debt are deferred and amortized using the effective interest method as a component of interest expense over the life of the related debt agreement.
Revenue Recognition 2020, 2019, and 2018	Revenue Recognition 2020 and 2019 The Company recognized revenues from the sale of solar tracking systems and parts and determines its revenue recognition through the following steps (i) identification of the contract or contracts with a customer, (ii) identification of the performance obligations within the contract, (iii) determination of the transaction price, (iv) allocation of the transaction price to the performance obligations within the contract, and (v) recognition of revenue when, or as the performance obligation has been satisfied. Performance Obligations The Company’s contracts with customers are predominately accounted for as one performance obligation, as the majority of tasks and services is part of a single project or capability. As these contracts are typically a customized assembly for a customer-specific solution, the Company uses the expected cost-plus margin approach to estimate the standalone selling price of each performance obligation. For contracts with multiple performance obligations, the Company allocates the contract’s transaction price to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract. In assessing the recognition of revenue, the Company also evaluates whether two or more contracts should be combined and accounted for as one contract and if the combined or single contract should be accounted for as multiple performance obligations which could change the amount of revenue and profit (loss) recorded in a period. Change orders may include changes in specifications or design, manner of performance, equipment, materials, scope of work, and/or the period of completion of the project. The Company analyzes its change orders to determine if they should be accounted for as a modification to an existing contract or a new stand-alone contract. The Company’s change orders are generally modifications to existing contracts and are included in the total estimated contract revenue when it is probable that the change order will result in additional value that can be reliably estimated and realized. The majority of the Company’s contracts do not contain variable consideration provisions as a continuation of the original contract. The Company’s performance obligations are satisfied predominately over-time as work progresses for its custom assembled solar systems, utilizing an output measure of completed products and based on the timing of the product’s shipments considering the shipping terms described in the contract. In certain situations, when product is still in our custody, and title and risk of loss has passed to the customer (known as bill-and-hold arrangement), revenue will be recognized when all the specific requirements for transfer of control under a bill-and-hold arrangement have been met. Revenue recognized for the Company’s part sales are recorded at a point in time and recognized when obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is in line with shipping terms. Contract Estimates Accounting for contracts utilizing the over-time method and their expected cost-plus margins is based on various assumptions to project the outcome of future events that can exceed a year. These assumptions include labor productivity and availability; the complexity of the work to be performed; the cost and availability of materials; and the availability and timing of funding from the customer. The Company reviews and updates its contract-related estimates each reporting period. The Company recognizes adjustments in estimated expected cost-plus on contracts under the cumulative catch-up method. Under this method, the impact of the adjustment on profit recorded to date is recognized in the period the adjustment is identified. Revenue and profit in future periods of contract performance is recognized using the adjusted estimate. If at any time the estimate of contract profitability indicates an anticipated loss on the contract, the Company recognizes the total loss in the period it is identified. Contract Balances The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables (contract assets), and deferred revenue (contract liabilities) on the consolidated balance sheets. The majority of the Company’s contract amounts are billed as work progresses in accordance with agreed-upon contractual terms, which generally coincide with the shipment of one or more phases of the project. Billing sometimes occurs subsequent to revenue recognition, resulting in contract assets. The changes in contract assets (i.e. unbilled receivables) and the corresponding amounts recorded in revenue relate to fluctuations in the timing and volume of billings for the Company’s revenue recognized over-time. As of December 31, 2020 and December 31, 2019, contract assets consisting of unbilled receivables totaling $18.1 million and $16.1 million, respectively, are included within accounts receivable on the consolidated balance sheets on a contract-by-contract basis at the end of the reporting period. The Company also receives advances or deposits from its customers, before revenue is recognized, resulting in contract liabilities. The changes in contract liabilities (i.e. deferred revenue) relate to advanced orders and payments received by the Company and are the result of customers looking to take advantage of certain U.S. federal tax incentives set to decrease at the end of 2019. Based on the terms of the tax incentives the customer must pay for the goods prior to December 31, 2019 which accounts for the increase in the advanced orders and payments and the resulting deferred revenue at December 31, 2019 and subsequent reduction for deliveries which occurred during the year ended December 31, 2020. As of December 31, 2020 and December 31, 2019, contract liabilities consisting of deferred revenue were $149.8 million and $328.8 million, respectively and were recorded on a contract-by-contract basis at the end of each reporting period. During the years ended December 31, 2020 and 2019, the Company converted $328.8 million and $21.8 million deferred revenue to revenue, respectively, which represented 100% of the prior years deferred revenue balance. Remaining Performance Obligations As of December 31, 2020, the Company had $455.3 million of remaining performance obligations. The Company expects to recognize revenue on 100% of these performance obligations in the next twelve months. Revenue Recognition - 2018 Products are sold by the Company for cash-in-advance and on credit. Revenue is recognized when persuasive evidence of an agreement exists and upon delivery and acceptance, or earlier if required by shipping terms, provided title is transferred, prices are fixed or determinable, and collection is deemed probable. Revenues are presented net of sales, use, value-added and other excise taxes collected by the Company that are remitted to various governmental authorities.

Income Taxes	Income Taxes The Company provides for income taxes based on the provisions of FASB ASC Topic 740, Income Taxes, which, among other things, requires that recognition of deferred income taxes be measured by the provisions of enacted tax rates in effect at the date of the consolidated financial statements. A valuation allowance is provided to reduce deferred income tax assets if it is more likely than not that all, or some portion, of such deferred tax assets will not be recognized. Provision for estimated income taxes is based upon elements of income and expense reported in the consolidated statements of operations. The Company also files certain corporate state income tax returns. Generally, the Company is subject to examination by U.S. federal (or state or local) income tax authorities for three years from the filing of a tax return. The current provision for income taxes represents actual or estimated amounts payable on tax return filings each year. Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying consolidated balance sheets, and for operating loss and tax credit carryforwards. The change in deferred tax assets and liabilities for the period measures the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws on deferred tax assets and liabilities are reflected as adjustments to the tax provision or benefit in the period of enactment. Adjustments for penalties and interest, if any, are also reflected in the current year tax provision or benefit. The Company determines whether uncertain tax positions are more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position.
Equity-Based Compensation	Equity-Based Compensation The Company recognizes equity-based compensation expense based on the equity award’s grant date fair value. The determination of the fair value of equity awards issued to employees of the Company is based upon the underlying share price and a number of assumptions, including volatility, performance period, risk-free interest rate and expected dividends. The Company accounts for forfeitures as they occur. The grant date fair value of each unit is amortized on a straight-line basis over the requisite service period.
Earnings per Share ("EPS")	Earnings per Share (“EPS”) Basic earnings per share, or EPS, is computed by dividing net income available to shareholders by the weighted average shares outstanding during the period. Diluted EPS takes into account the potential dilution that could occur if securities or other contracts to issue shares, such as stock options and unvested restricted stock, were exercised and converted into shares. Diluted EPS is computed by dividing net income available to shareholders by the weighted average shares outstanding during the period, increased by the number of additional shares that would have been outstanding if the potential shares had been issued and were dilutive.
Credit Concentration	Credit Concentration Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, restricted cash and accounts receivable. The Company has no significant off balance sheet concentrations of credit risk. The Company maintains its cash and restricted cash with financial institutions that are believed to be of high credit quality and has not experienced any material losses relating to any cash and restricted cash.
Fair Value	Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company follows a fair value hierarchy which requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Three levels of inputs may be used to measure fair value, as follows: • Level 1 - Quoted prices in active markets for identical assets or liabilities. • Level 2 - Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 - Unobservable inputs that are supported by little or no market activity that are significant to the fair value of the assets or liabilities. Assets valued using Level 1 inputs are determined by quoted market prices derived from an active market and Level 2 inputs are based primarily on quoted prices for similar assets in active or inactive markets. Level 3 inputs are valued by management’s assumptions about the assumptions the market participants would utilize in pricing the asset. The fair values of the Company’s cash, restricted cash, accounts receivable, and accounts payable approximate their carrying values due to their short maturities. The carrying value of the Company’s notes payable and related party loans approximates their fair values, as they are based on current market rates at which the Company could borrow funds with similar terms.
New Accounting Standards	New Accounting Standards To be adopted In February 2016, the FASB issued ASU No. 2016-02 (Topic 842) “Leases” which supersedes the lease recognition requirements in ASC Topic 840, “Leases” . Under ASU No. 2016-02, lessees are required to recognize assets and liabilities on the consolidated balance sheets for most leases and provide enhanced disclosures. Leases will continue to be classified as either finance or operating. For companies that are not emerging growth companies (“EGCs”), the ASU is effective for fiscal years beginning after December 15, 2018. For EGCs, the ASU is effective for fiscal years beginning after December 15, 2021. The Company plans to adopt the new standard using the modified retrospective method, under which the Company will apply Topic 842 to existing and new leases as of the effective date of January 1, 2021, but prior periods will not be restated and will continue to be reported under Topic 840 guidance in effect during those periods. The Company anticipates that the adoption will not have a material impact on its consolidated statements of operations or its consolidated statements of cash flows but expects to recognize right-of-use assets and liabilities for lease obligations associated with its operating leases. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses , which was subsequently amended by ASU No. 2018-19 and ASU No. 2019-10, requires the measurement of expected credit losses for financial instruments carried at amortized cost held at the reporting date based on historical experience, current conditions and reasonable forecasts. The updated guidance also amends the current other-than-temporary impairment model for available-for-sale debt securities by requiring the recognition of impairments relating to credit losses through an allowance account and limits the amount of credit loss to the difference between a security’s amortized cost basis and its fair value. In addition, the length of time a security has been in an unrealized loss position will no longer impact the determination of whether a credit loss exists. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The standard is effective for the fiscal year beginning after December 15, 2022, or December 15, 2021 if we were to lose EGC’s status in 2021. The Company will continue to assess the possible impact of this standard, but currently does not expect the adoption of this standard will have a significant impact on its consolidated financial statements and its limited history of bad debt expense relating to trade accounts receivable. In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU No. 2019-12”), which is intended to simplify various aspects of the accounting for income taxes. ASU No. 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. This standard is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its consolidated financial statements and related disclosures. Adopted In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement - Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement
