Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES This summary of significant accounting policies of Sunworks, Inc. is presented to assist in understanding the Company’s financial statements. These accounting policies conform to Generally Accepted Accounting Principles used in the United States (“GAAP”) and have been consistently applied in the preparation of the financial statements. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Sunworks, Inc., and its wholly owned operating subsidiaries, Sunworks United, MD Energy, and Plan B. All material intercompany transactions have been eliminated upon consolidation of these entities. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include estimates used to review the Company’s goodwill, impairments and estimations of long-lived assets, revenue recognition on construction contracts recognized over time, allowances for uncollectible accounts, operating lease right-of-use assets and liabilities, warranty reserves, inventory valuation, valuations of non-cash capital stock issuances and the valuation allowance on deferred tax assets. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable in the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Revenue Recognition Revenues and related costs on construction contracts are recognized as the performance obligations for work are satisfied over time in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers The cost of materials or equipment will generally be excluded from our recognition of profit, unless specifically produced or manufactured for a project, because such costs are not considered to be a measure of progress. All un-allocable indirect costs and corporate general and administrative costs are charged to the periods as incurred. However, in the event a loss on a contract is foreseen, the Company will recognize the loss in the period it is determined. Revisions in cost and profit estimates during the course of the contract are reflected in the accounting period in which the facts which require the revision become known. We use an input method based on costs incurred as we believe that this method most accurately reflects our progress toward satisfaction of the performance obligation. Under this method, revenue arising from fixed-price construction contracts is recognized as work is performed based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions, and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Contract assets represent revenues recognized in excess of amounts invoiced to customers on contracts in progress. Contract liabilities represent amounts invoiced to customers in excess of revenues recognized on contracts in progress. Accounts Receivable Accounts receivables are recorded on contracts for amounts currently due based upon progress billings, as well as retention, which are collectible upon completion of the contracts. Retention receivable is the amount withheld by a customer until a contract is completed. Retention receivables of $392 and $1,027 were included in the balance of trade accounts receivable as of December 31, 2020, and 2019, respectively. The Company performs ongoing credit evaluation of its customers. Management monitors outstanding receivables based on factors surrounding the credit risk of specific customers, historical trends, age of receivables and other information, and records bad debts using the allowance method. Accounts receivable are presented net of an allowance for doubtful accounts of $253 at December 31, 2020, and $350 at December 31, 2019. During 2020, $710 was recorded as bad debt expense compared to $111 in 2019. Customer Deposits Customer deposits are recorded for funds remitted by the Company’s customers in advance worked performed and a progress billing milestone being completed. Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. Restricted Cash The Company considers restricted cash to be cash balances that have legal and/or contractual restrictions imposed by a third party and are restricted as to withdrawal or use except for the specified purpose. Concentration Risk Cash includes amounts deposited in financial institutions in excess of insurable Federal Deposit Insurance Corporation (“FDIC”) limits. At times throughout the year, the Company may maintain cash balances in certain bank accounts in excess of FDIC limits. As of December 31, 2020 and 2019, the cash balance in excess of the FDIC limits was $38,981 and $3,405, respectively. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk in these accounts. Inventory Inventory is valued at lower of cost or net realizable value determined by the first-in, first-out method. Inventory primarily consists of panels, inverters, batteries and mounting racks and other materials. The Company reviews the cost of inventories against their estimated net realizable value and records write-downs if any inventories have costs in excess of their net realizable values. Inventory is presented net of an allowance of $309 at December 31, 2020 and $50 at December 31, 2019. Property and Equipment Property and equipment are stated at cost. Depreciation for property and equipment commences when it is put into service and are depreciated using the straight-line method over property and equipment’s estimated useful lives: Machinery & equipment 3-7 Years Office equipment & furniture 5-7 Years Computers & software 3-5 Years Vehicles & trailers 3-7 Years Leasehold improvements 3-5 Years Depreciation and amortization expense for the years ended December 31, 2020 and 2019 was $337 and $353, respectively. Leases The Company determines if an arrangement is a lease at inception. Operating lease right-of-use assets (“ROU assets”) and short-term and long-term lease liabilities are included on the face of the consolidated balance sheet. If the Company had finance lease ROU assets, such assets would be presented within other assets, and finance lease liabilities would be presented appropriately within liabilities. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component. For lease agreements with terms less than 12 months, the Company has elected the short-term lease measurement and recognition exemption, and the Company recognizes such lease payments on a straight-line basis over the lease term. Warranty Liability The Company establishes warranty liability reserves to provide for estimated future expenses as a result of installation, product and performance defects, product recalls and litigation incidental to the Company’s business. Liability estimates are determined based on management’s judgment, considering such factors as historical experience, the likely current cost of corrective action, manufacturers’ and subcontractors’ participation in sharing the cost of corrective action, and consultations with third party experts such as engineers. Solar panel manufacturers currently provide substantial warranties of between ten to twenty-five years with full reimbursement to replace and install replacement panels. Inverter manufacturers currently provide warranties covering ten to fifteen years including replacement and installation. The warranty liability for estimated future warranty costs at December 31, 2020 and 2019 is $1,131 and $441, respectively. Advertising and Marketing The Company expenses advertising and marketing costs as incurred. Advertising and marketing costs may include printed material, billboards, sponsorships, direct mail, radio, telemarketing, tradeshow costs, magazine, and catalog advertisement. Advertising and marketing costs for the years ended December 31, 2020 and 2019 were $107 and $123, respectively. Stock-Based Compensation The Company periodically issues stock options and warrants to employees and non-employees. The Company accounts for stock option and warrant grants issued and vesting to employees based on the authoritative guidance provided by the Financial Accounting Standards Board (“FASB”) whereas the value of the award is measured on the date of grant and recognized over the vesting period. The Company accounts for stock option and warrant grants issued and vesting to non-employees in accordance with the authoritative guidance of the FASB whereas the value of the stock compensation is based upon the measurement date as determined at either a) the date at which a performance commitment is reached, or b) at the date at which the necessary performance to earn the equity instruments is complete. Non-employee stock-based compensation charges generally are amortized over the vesting period on a straight-line basis. In certain circumstances where there are no future performance requirements by the non-employee, option grants are immediately vested and the total stock-based compensation charge is recorded in the period of the measurement date. Basic and Diluted Net (Loss) per Share Calculations (Loss) per Share dictates the calculation of basic earnings (loss) per share and diluted earnings per share. Basic earnings (loss) per share are computed by dividing income (loss) available to common shareholders by the weighted-average number of common shares available. Diluted earnings per share is computed similar to basic earnings per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. The shares for employee options, restricted stock, warrants and convertible notes were not used in the calculation of the net loss per share. A net loss causes all outstanding common stock options to be anti-dilutive. As a result, the basic and diluted losses per common share are the same for the year ended December 31, 2020 and 2019. As of December 31, 2020, the potentially dilutive securities were excluded from the computations of weighted average shares outstanding including 88,441 stock options. As of December 31, 2019, the potentially dilutive securities were excluded from the computations of weighted average shares outstanding including 143,623 stock options, 5,952 restricted stock grants, 428,143 warrants. Dilutive per share amounts are computed using the weighted-average number of common shares outstanding and potentially dilutive securities, using the treasury stock method, if their effect would be dilutive. Long-Lived Assets The Company reviews its property and equipment and any identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The test for impairment is required to be performed by management at least annually. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted operating cash flow expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell. Goodwill The Company accounts for business combinations under the acquisition method of accounting in accordance with ASC 805, “Business Combinations,” where the total purchase price is allocated to the tangible and identified intangible assets acquired and liabilities assumed based on their estimated fair values. The purchase price is allocated using the information currently available, and may be adjusted, up to one year from acquisition date, after obtaining more information regarding, among other things, asset valuations, liabilities assumed and revisions to preliminary estimates. The purchase price in excess of the fair value of the tangible and identified intangible assets acquired less liabilities assumed is recognized as goodwill. The Company retains a valuation consulting firm to test for goodwill impairment in the fourth quarter of each year and whenever events or circumstances indicate that the carrying amount of an asset exceeds its fair value and may not be recoverable. In accordance with the Company’s policies, the Company performed a quantitative assessment of goodwill at December 31, 2019 and no impairment was found. As a result of the events and circumstances resulting from the COVID-19 pandemic, the Company’s outlook for revenue, profitability and cash flow had deteriorated. Therefore, the Company performed another quantitative assessment of goodwill at March 31, 2020, where it was determined that the carrying value of goodwill exceeded its fair value at March 31, 2020. As a result, the Company recorded an impairment of $4,000. The Company performed another quantitative assessment of goodwill at December 31, 2020 and no additional impairment was found. Fair Value of Financial Instruments Disclosures about fair value of financial instruments, requires disclosure of the fair value information, whether or not recognized in the balance sheet, where it is practicable to estimate that value. As of December 31, 2020, the amounts reported for cash, accrued interest and other expenses, and notes payable approximate the fair value because of their short maturities. The Company accounts for financial instruments measured as fair value on a recurring basis under ASC Topic 820. ASC Topic 820 defines fair value, established a framework for measuring fair value in accordance with accounting principles generally accepted in the United States and expands disclosures about fair value measurements. 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. ASC Topic 820 established a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). These tiers include: ● Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; ● Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. Income Taxes The Company uses the liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to financial statements carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. The measurement of deferred tax assets and liabilities is based on provisions of applicable tax law. The measurement of deferred tax assets is reduced, if necessary, by a valuation allowance based on the amount of tax benefits that, based on available evidence, is not expected to be realized. Reclassifications Certain reclassifications have been made to prior year’s financial statement to conform to classifications used in the current year. Segment Reporting Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker, or decision-making group, in deciding the method to allocate resources and assess performance. The Company currently has one reportable segment for financial reporting purposes, which represents the Company’s core business. New Accounting Pronouncements Adopted Accounting Pronouncements In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, U.S. GAAP requires the performance of procedures to determine the fair value at the impairment testing date of assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, the amendments under this ASU require the goodwill impairment test to be performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The ASU became effective for the Company on January 1, 2020 and was followed in the preparation of a quantitative assessment of goodwill at March 31, 2020, where it was determined that the carrying value of goodwill exceeded its fair value at March 31, 2020. As a result, we recorded an impairment of $4,000. The quantitative assessment performed at December 31, 2020 determined that there was no additional impairment. Management reviewed currently issued pronouncements during the year ended December 31, 2020, and believes that any other recently issued, but not yet effective, accounting standards, if currently adopted, would not have a material effect on the accompanying consolidated financial statements. Revision of 2019 Amounts Previously Reported In the preparation of this Annual Report on Form 10-K for the year ended December 31, 2020, the Company determined that it had omitted to record a deemed dividend on the repricing of warrants it issued in 2015. The 2019 sales of common stock pursuant to an “at the market offering” triggered down round provisions associated with 428,143 warrants that resulted in an understatement of the net loss attributable to common shareholders and loss per share attributable to common shareholders for the year ended December 31, 2019. The warrants expired unexercised in March 2020 (see Note 12). The Company assessed the materiality of this misstatement in accordance with Staff Accounting Bulletin No. 108 – “Qualifying Misstatements” and concluded this error was not qualitatively material as there was no impact on the consolidated balance sheet, statement of shareholders’ equity, statement of cash flows and statement of operations other than the net loss available to common shareholders. As such, the correction of the error is only revised in the December 31, 2019 consolidated statement of operations presented herein. The effect of this revision on the line items within the statement of operations for the year ended December 31, 2019 was as follows: For the Year Ended December 31, 2019 As previously Adjustment As revised Consolidated Statement of Operations Net Loss $ (9,186 ) $ - $ (9,186 ) Deemed dividend on repricing of warrants $ - $ (1,430 ) $ (1,430 ) Net Loss available to common shareholders $ (9,186 ) $ (1,430 ) $ (10,616 ) Net Loss per common share, basic and diluted $ (2.07 ) $ (0.32 ) $ (2.39 )

Acquisition Promissory Note	8. ACQUISITION PROMISSORY NOTE On February 28, 2015, the Company issued a 4% convertible promissory note in the aggregate principal amount of $2,650 as part of the consideration paid to acquire 100% of the total outstanding stock of MD Energy. The note was convertible into shares of common stock on or after each of the following dates: November 30, 2015, November 30, 2016 and November 30, 2017. The conversion price was $18.20 per share. A beneficial conversion feature of $3,262 was calculated but capped at the $2,650 value of the note. The beneficial conversion feature was calculated by multiplying the difference between the fair value of stock at the date of the note, $40.60, less the conversion price of $18.20, multiplied by the maximum number of shares subject to conversion, 145,604. In November 2015, the Company issued 48,535 shares of common stock upon conversion of the principal amount of $883. Commencing on March 31, 2015, and each quarter thereafter during the first two (2) years of the note, the Company made quarterly interest only payments to the shareholder for accrued interest on the Note during the quarter. Commencing with the quarter ending on June 30, 2017, the Company began to make quarterly payments of interest accrued on the convertible note during the prior quarter plus $151 with the final payment of all outstanding principal and accrued but unpaid interest on the convertible note due and payable on February 28, 2020, the maturity date.

Promissory Notes Payable	9. PROMISSORY NOTES PAYABLE On April 27, 2018, the Company entered into a Loan Agreement (the “Loan Agreement”) with CrowdOut Capital, Inc. (“CrowdOut”) pursuant to which the Company issued an aggregate of $3,750 in promissory notes (the “Notes”), of which $3,000 was a Senior Note and $750 were Subordinated Notes. The Subordinated Notes were funded by the Company’s Chief Executive Officer, Charles Cargile, and the Company’s President of Commercial Operations, Kirk Short. The Notes bore interest at the rate of the one-month LIBOR plus 950 basis points and were originally scheduled to mature on June 30, 2020. The maturity date of the Notes was subsequently extended to January 31, 2021 as described below. On June 3, 2019, the Company entered into an amendment to its Loan Agreement (the “First Amendment”), pursuant to which the maturity date of the $3,000 Senior Note and $750 Subordinated Notes was extended from June 30, 2020 to January 31, 2021. In connection with entering into the First Amendment, the Company agreed to issue to CrowdOut, as the holder of the Senior Note, 57,143 shares of common stock as an amendment fee (the “Amendment Fee”) pursuant to the Company’s shelf registration statement on Form S-3. Based upon the closing price of the Company’s common stock on June 17, 2019, the day of issuance, the 57,143 shares were valued at $344. The $344 Amendment Fee plus $7 for CrowdOut Amendment related legal fees were added to the debt issuance costs and were amortized over the remaining life of the loan (see discussion below). The Notes could be prepaid in whole without the consent of the lender or in part with the consent of the lender. At the time the Notes were paid in full, the Company paid CrowdOut, as the holder of the Senior Note, an exit fee of $435. The Company accrued the exit fee of $435 over the extended remaining life of the Loan Agreement and recognized the exit fee as interest expense. For the years ended December 31, 2020 and 2019, the exit fee recorded as interest expense was $141 and $160, respectively. On January 28, 2020, the Company entered into a second amendment to its Loan Agreement (the “Second Amendment” and, together with the First Amendment, the “Amendments”) pursuant to which the Loan Agreement was amended to permit the partial prepayment of One Million Five Hundred Thousand Dollars $(1,500) of the Senior Note loan amount without any prepayment fees. In addition, the Second Amendment provided that, unless an event of default occurred under the Loan Agreement, CrowdOut no longer had the right to designate a member to the Company’s Board of Directors. Accordingly, in January 2020, $1,500 of the $3,000 Senior Note was paid. In connection with the issuance of the Senior Note, the Company entered into a security agreement (the “Security Agreement”) pursuant to which the Company granted to CrowdOut a security interest in certain of the Company’s assets to secure the prompt payment, performance and discharge in full of all of the Company’s obligations under the Senior Note. The Company also entered into a subordination agreement with the holders of the Subordinated Notes and the Senior Note pursuant to which the Subordinated Notes were subordinated to the Senior Note. The Loan Agreement contained certain customary events of default including, but not limited to, default in payment of any sum payable thereunder, breaches of representations or warranties thereunder, the occurrence of an event of default under the transaction documents, change in control of the Company, filing of bankruptcy and the entering or filing of certain monetary judgments against the Company. Upon the occurrence of an event of default the outstanding principal amount of the Notes, plus accrued but unpaid interest and other amounts owing in respect thereof, would become, at the giving of notice by CrowdOut, immediately due and payable. Interest on overdue payments upon the occurrence of an event of default would accrue interest at a rate equal to the lesser of 18% per annum or the maximum rate permitted under applicable law. Additionally, the Loan Agreement included a subjective event of default clause if CrowdOut reasonably determined that an event has occurred that would reasonably be expected to have had a “material adverse effect.” In conjunction with the Loan Agreement and Amendments, the Company recorded $468 of capitalized debt issuance costs. The debt issuance costs were amortized over the life of the Loan Agreement and recognized as interest expense. The balance payable under the Notes was reported net of the unamortized portion of the debt issuance costs. The Company recorded amortization of the debt issuance cost of $266 and $159 as interest expense during the years ended December 31, 2020 and 2019, respectively. The $266 recorded as amortization of the debt issuance costs during the year ended December 31, 2020 includes $98 of expense required as a result of the $1,500 prepayment of the $3,000 Senior Note and required write-off of a proportionate share of the associated debt issuance cost. On April 28, 2020, the Company entered into a Third Amendment to Loan Agreement (“Third Amendment”) with CrowdOut. Pursuant to the Third Amendment, CrowdOut provided its consent permitting the Company to obtain its Paycheck Protection Program (“PPP”) loan. On December 4, 2020, the Company paid the remaining outstanding balance of the $1,500 Senior Note and $750 of Subordinated Notes together with the $435 exit fee. No balance or obligations remain outstanding as of December 31, 2020. Promissory notes payable at December 31, 2020 and 2019 are as follows: 2020 2019 Promissory notes payable $ - $ 3,750 Less: debt issuance costs - (266 ) Promissory notes payable, net $ - $ 3,484

As modified by the subsequent PPP Flexibility Act of 2020, proceeds from the loan were used to cover documented expenses related to payroll, rent and utilities, during the 24-week period after the cash was received by the Company. The 24-week period ended on October 12, 2020. The loan is being accounted for as a financial liability in accordance with FASB ASC 470 . The eligible forgiveness amount allows for not more than 40% of the forgiveness to be for non-payroll items and is subject to reduction if employees are terminated or wages are reduced. The remaining unforgiven amount of the loan bears interest at 1% per annum. Eighteen equal principal and interest payments of $159 are deferred for up to ten months after the initial 24-week covered period, with payments scheduled to begin on August 12, 2021; however, interest is being accrued from the inception date of the loan. There are no collateral requirements or prepayment penalties associated with the loan. The underlying expenses, included in the forgiveness application filed with the Small Business Administration (“SBA”), are sufficient to have the entire $2,847 PPP loan completely forgiven. Until final approval is received from the SBA and the Company has been “legally released” from the liability, there is no guarantee when forgiveness will be received or whether the loan will be completely or partially forgiven.

On August 29, 2019, the board of directors of the Company approved the reverse stock split at a ratio of 1-for-7 which went into effect at the open of trading on August 30, 2019. At the effective time of the reverse stock split, every seven shares of issued and outstanding common stock was converted into one share of issued and outstanding common stock. The authorized shares of 200,000,000 and the par value of $0.001 remained the same. All shares and related financial information in this Form 10-K is retroactively stated to reflect this 1-for-7 reverse stock split. Due to the 1-for-7 reverse stock split that went into effect on August 30, 2019, a rounding of common stock shares was required due to partial share amounts that are rounded up to the next whole share. This resulted in an increase in shares of common stock of 5,585. As approved by stockholders during the 2020 annual meeting on September 18, 2020, a Certificate of Amendment of the Certificate of Incorporation was filed with the Secretary of State of the State of Delaware to reduce the total number of shares of all classes of capital stock of the Company to fifty-five million (55,000,000) shares, consisting of fifty million (50,000,000) shares of common stock, par value $0.001 per share and five million (5,000,000) shares of preferred stock, par value $0.001 per share.

The base prospectus was contained within the Prior Registration Statement. The Prior Registration Statement allowed the Company to offer and sell, from time to time in one or more offerings, any combination of common stock, preferred stock, warrants, or units having an aggregate initial offering price not to exceed $50 million. As of December 31, 2020, all of the shares of common stock registered under the Prior Registration Statement have been sold. Sales of shares under the First ATM Agreement were deemed to be “at the market offerings” as defined in Rule 415 promulgated under the Securities Act. The Agent acted as sales agent and used commercially reasonable efforts to sell on the Company’s behalf all of the First Placement Shares requested to be sold by the Company, consistent with its normal trading and sales practices, on mutually agreed terms between the Agent and the Company. 9,817,343 shares of common stock (the “First Placement Shares”) were sold under the First ATM Agreement between January 1, 2020 and March 26, 2020, pursuant to a prospectus supplement that was filed with the SEC on June 6, 2019.

The Prior Registration Statement was filed in reliance on Instruction I.B.6. of Form S-3, which imposes a limitation on the maximum amount of securities that the Company could sell pursuant to the Prior Registration Statement during any twelve-month period. At the time the Company sold the First Placement Shares pursuant to the Prior Registration Statement, the amount of securities to be sold plus the amount of any securities the Company had sold during the prior twelve months in reliance on Instruction I.B.6. could not exceed one-third of the aggregate market value of the Company’s outstanding common stock held by non-affiliates as of a day during the 60 days immediately preceding such sale as computed in accordance with Instruction I.B.6. Therefore, the Company was not eligible to sell additional shares under the Prior Registration Statement at that time. $20 Million Prospectus Supplement – November 25, 2020 3,877,746 shares of common stock (the “Second Placement Shares”) were sold under the First ATM Agreement between November 25, 2020 and December 2, 2020, pursuant to a prospectus supplement that was filed with the SEC on November 25, 2020.

The stock options vest at various times and are exercisable for a period of five years from the date of grant at exercise prices ranging from $2.10 to $21.70 per share, the market value of the Company’s common stock on the date of each grant. The Company determined the fair market value of these options by using the Black Scholes option valuation model. During 2020, using cashless option exercises, 26,116 options were exercised resulting in 13,924 net shares being issued. A summary of the Company’s stock option activity and related information follows: 2020 2019 Weighted Weighted Number Average Number Average of Exercise of Exercise Options Price Options Price Outstanding, beginning January 1 143,623 $ 8.99 224,127 $ 12.11 Granted - - 55,707 2.73 Exercised (26,116 ) 2.66 - - Forfeited (29,066 ) 8.53 (136,211 ) 11.49 Expired - - - - Outstanding, end of December 31 88,441 $ 11.02 143,623 $ 8.99 Exercisable at the end of December 31 71,502 $ 12.81 85,181 $ 12.18 Weighted average fair value of options granted during period $ - $ 1.31 The following summarizes the options to purchase shares of the Company’s common stock which were outstanding at December 31, 2020: Weighted Average Remaining Exercisable Stock Options Stock Options Contractual Prices Outstanding Exercisable Life (years) $ 18.76 12,142 12,142 0.28 $ 20.16 7,142 7,142 0.67 $ 21.70 7,142 7,142 0.84 $ 10.50 17,140 17,140 1.38 $ 10.71 1,428 1,428 1.67 $ 6.93 7,142 6,547 2.25 $ 8.68 7,142 6,348 2.37 $ 7.63 12,855 11,367 2.41 $ 2.31 1,024 86 2.94 $ 2.10 4,436 341 3.01 $ 3.07 6,483 1,621 3.62 $ 2.52 4,365 198 3.75 88,441 71,502 Aggregate intrinsic value of options outstanding and exercisable at December 31, 2020 and 2019 was $5 and $0, respectively. Aggregate intrinsic value represents the difference between the Company’s closing stock price on the last trading day of the fiscal period, which was $5.12 and $1.25 as of December 31, 2020 and 2019, respectively, and the exercise price multiplied by the number of options outstanding. The Company recorded stock-based compensation for issued options of $84 and $184 for the years ended December 31, 2020 and 2019, respectively. Restricted Stock Grant to Chairman and Former CEO With an effective date of March 29, 2017, subject to the Sunworks, Inc. 2016 Equity Incentive Plan, (the “2016 Plan”) the Company entered into a restricted stock grant agreement (the “March 2017 RSGA”) effective March 29, 2017 with its then Chief Executive Officer, Charles Cargile. All shares issuable under the March 2017 RSGA are valued as of the grant date at $10.50 per share. The March 2017 RSGA provided for the issuance of up to 71,429 shares of the Company’s common stock. The restricted shares vested as follows: 23,810 of the restricted shares shall vested on the one (1) year anniversary of the effective date, and the balance, or 47,619 restricted shares, vested in twenty-four (24) equal monthly installments commencing on the one (1) year anniversary of the effective date. Vesting of the shares and recognition of stock-based compensation expense for the March 2017 RSGA ended as of March 29, 2020. In the years ended December 31, 2020 and 2019, stock-based compensation expense of $63 and $250, respectively was recognized for the March 2017 RSGA. The total combined option and restricted stock compensation expense recognized in the statements of operations during the years ended December 31, 2020 and 2019 was $147 and $434, respectively. Warrants As part of a March 2015 capital raise, the Company issued common stock with warrants to purchase 428,572 shares of common stock at an exercise price of $29.05 per share. During 2015, 429 warrants were exercised. No additional warrants were ever exercised after 2015. The warrants expired on March 9, 2020. The sale and issuances of common stock pursuant to various ATM agreements in 2019 and 2020 described in Note 11 triggered the down round provision in the warrants resulting in the Company recording a deemed dividend of approximately $60 and $1,430 in the years ended December 31, 2020 and 2019, respectively (see Note 2). Pursuant to the down round provisions of the warrants, the exercise price decreased from $29.05 to $1.20 at December 31, 2019. In 2020, continued common stock issuances caused the exercise price to decrease from $1.20 to $0.65 until on March 9, 2020, when the warrants expired unexercised. The deemed dividend has no cash impact. For financial statement presentation purposes, the deemed dividend is shown as an increase in the net loss attributable to common shareholders, increasing the loss per share for common stock by approximately $0.01 and $0.32 per common share for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020, the Company had no remaining stock purchase warrants outstanding. See Note 2 for a discussion of the impact of the accounting for the warrant deemed dividend on the 2019 consolidated financial statements.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE13 – INCOME TAXES The Company had no income tax expense due to operating losses incurred for the years ended December 31, 2020 and 2019. The Company accounts for income taxes in accordance with ASC 740, which requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carryforward period No tax benefit has been reported in the 2020 financial statements, since the potential tax benefit is offset by a valuation allowance of the same amount. The Company’s income tax expense for the years ended December 31, 2020 and 2019 are summarized below: December 31, December 31, Current: Federal $ - $ - State - - Foreign - - Total current $ - $ - Deferred: Federal $ (2,863 ) $ (2,519 ) State (599 ) - Change in valuation allowance 3,462 2,519 Total deferred - - Income tax provision (benefit) $ - $ - The Company’s deferred tax assets are as follows: December 31, December 31, Deferred tax assets: Net operating loss carryforwards $ 8,270 $ 5,910 Research and development tax credit 248 173 Disallowed interest 579 - Warranty, inventory and accounts receivable allowances 462 109 Depreciation 94 42 Other 170 127 Total deferred tax assets 9,823 6,361 Valuation allowances (9,823 ) (6,361 ) Net deferred tax assets $ - $ - The income tax provision differs from the amount of income tax determined by applying the U.S. federal income tax rate to pretax income from continuing operations for the year ended December 31, 2020 and 2019 due to the following: 2020 2019 Net taxable (loss) at effective tax rates $ (3,347 ) $ (2,480 ) Stock compensation expense 31 91 State tax - - Impairment of goodwill 840 - Other - 4 Valuation allowance 2,476 2,385 Income tax expense $ - $ - At December 31, 2020, the Company had federal, and California net operating loss carryforwards of approximately $31 million and $28 million, respectively. In addition, the Company has federal and California research and development tax credit carryforwards of approximately $172 and $75, respectively. The federal net operating losses incurred in years beginning after January 1, 2018 in the amount of $19 million can be carried forward indefinitely. The remaining $12 million of federal net operating loss, research tax credit carryforwards and California net operating loss carryforwards will begin to expire in 2029 unless previously utilized. The California research and development credit carryforwards will carry forward indefinitely until utilized. Utilization of U.S. net operating losses and tax credit carryforwards may be limited by “ownership change” rules, as defined in Sections 382 and 383 of the Code. Similar rules may apply under state tax laws. The Company has not conducted a study to-date to assess whether a limitation would apply under Sections 382 and 383 of the Code as and when it starts utilizing its net operating losses and tax credits. The Company will continue to monitor activities in the future. In the event the Company should experience an ownership change in the future, the amount of net operating losses and research and development credit carryovers available in any taxable year could be limited and may expire unutilized. The CARES Act was signed into law on March 27, 2020 as a response to the economic challenges facing U.S. businesses caused by the COVID-19 global pandemic. The CARES Act allowed net operating loss incurred in 2018-2020 to be carried back five years or carried forward indefinitely, and to be fully utilized without being subjected to the 80% taxable income limitation. Net operating losses incurred after December 31, 2020 will be subjected to the 80% taxable income limitation. In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion, or all, of the deferred tax asset will be realized. The ultimate realization of deferred tax assets is dependent upon the Company attaining future taxable income during periods in which those temporary differences become deductible. Due to the uncertainty surrounding the realization of the benefits of its deferred assets, including NOL carryforwards, the Company has provided a 100% valuation allowance on its deferred tax assets at December 31, 2020. The Company accounts for uncertain tax positions in accordance with the provisions of ASC 740, Income Taxes

There are no pending significant legal proceedings to which the Company is a party for which management believes the ultimate outcome would have a negative impact on the Company’s financial position except as noted below: On October 12, 2020, a putative class complaint was filed by a purported stockholder of Sunworks regarding the contemplated but terminated merger among The Peck Company Holdings, Inc. (“Peck”), Peck Mercury, Inc. (“Merger Sub’) and Sunworks (the “Merger”). The complaint names, as defendants, each of the Sunworks’ Board of Directors (the “Directors”) and asserts that the Directors breached their fiduciary duties. The plaintiff alleges that the consideration to be received by stockholders of Sunworks was inadequate and that the Registration Statement on Form S-4 contained materially incomplete and misleading information regarding the proposed Merger. On November 24, 2020, the parties filed a joint stipulation to dismiss the action without prejudice with a reservation for plaintiff to seek attorneys’ fees and costs; the Court granted that stipulation and ordered the dismissal on November 25, 2020. There are seven other actions related to the same proposed transaction, of which six have been voluntarily dismissed by the respective plaintiffs. All eight complaints seek: (i) injunctive relief to prevent the consummation of the Merger; (ii) damages suffered by the plaintiff; and (iii) an award of Plaintiff’s expense, including reasonable attorneys’ and experts’ fees. On November 2, 2020, Sunworks filed a Form 8-K that included supplemental disclosures intended to moot the allegations in all of the complaints. Sunworks and the Directors believe the claims asserted in the complaints are without merit and intend to vigorously defend themselves. Sunworks has had on-going settlement discussion, but Sunworks has not entered into any agreement to settle any of the lawsuits. Sunworks is insured against such claims and losses.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of Sunworks, Inc., and its wholly owned operating subsidiaries, Sunworks United, MD Energy, and Plan B. All material intercompany transactions have been eliminated upon consolidation of these entities.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include estimates used to review the Company’s goodwill, impairments and estimations of long-lived assets, revenue recognition on construction contracts recognized over time, allowances for uncollectible accounts, operating lease right-of-use assets and liabilities, warranty reserves, inventory valuation, valuations of non-cash capital stock issuances and the valuation allowance on deferred tax assets. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable in the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Revenue Recognition	Revenue Recognition Revenues and related costs on construction contracts are recognized as the performance obligations for work are satisfied over time in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers The cost of materials or equipment will generally be excluded from our recognition of profit, unless specifically produced or manufactured for a project, because such costs are not considered to be a measure of progress. All un-allocable indirect costs and corporate general and administrative costs are charged to the periods as incurred. However, in the event a loss on a contract is foreseen, the Company will recognize the loss in the period it is determined. Revisions in cost and profit estimates during the course of the contract are reflected in the accounting period in which the facts which require the revision become known. We use an input method based on costs incurred as we believe that this method most accurately reflects our progress toward satisfaction of the performance obligation. Under this method, revenue arising from fixed-price construction contracts is recognized as work is performed based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligations. Changes in job performance, job conditions, and estimated profitability, including those arising from contract penalty provisions, and final contract settlements may result in revisions to costs and income and are recognized in the period in which the revisions are determined. Contract assets represent revenues recognized in excess of amounts invoiced to customers on contracts in progress. Contract liabilities represent amounts invoiced to customers in excess of revenues recognized on contracts in progress.
Accounts Receivable	Accounts Receivable Accounts receivables are recorded on contracts for amounts currently due based upon progress billings, as well as retention, which are collectible upon completion of the contracts. Retention receivable is the amount withheld by a customer until a contract is completed. Retention receivables of $392 and $1,027 were included in the balance of trade accounts receivable as of December 31, 2020, and 2019, respectively. The Company performs ongoing credit evaluation of its customers. Management monitors outstanding receivables based on factors surrounding the credit risk of specific customers, historical trends, age of receivables and other information, and records bad debts using the allowance method. Accounts receivable are presented net of an allowance for doubtful accounts of $253 at December 31, 2020, and $350 at December 31, 2019. During 2020, $710 was recorded as bad debt expense compared to $111 in 2019.
Customer Deposits	Customer Deposits Customer deposits are recorded for funds remitted by the Company’s customers in advance worked performed and a progress billing milestone being completed.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents.
Restricted Cash	Restricted Cash The Company considers restricted cash to be cash balances that have legal and/or contractual restrictions imposed by a third party and are restricted as to withdrawal or use except for the specified purpose.
Concentration Risk	Concentration Risk Cash includes amounts deposited in financial institutions in excess of insurable Federal Deposit Insurance Corporation (“FDIC”) limits. At times throughout the year, the Company may maintain cash balances in certain bank accounts in excess of FDIC limits. As of December 31, 2020 and 2019, the cash balance in excess of the FDIC limits was $38,981 and $3,405, respectively. The Company has not experienced any losses in such accounts and believes it is not exposed to any significant credit risk in these accounts.
Inventory	Inventory Inventory is valued at lower of cost or net realizable value determined by the first-in, first-out method. Inventory primarily consists of panels, inverters, batteries and mounting racks and other materials. The Company reviews the cost of inventories against their estimated net realizable value and records write-downs if any inventories have costs in excess of their net realizable values. Inventory is presented net of an allowance of $309 at December 31, 2020 and $50 at December 31, 2019.
Property and Equipment	Property and Equipment Property and equipment are stated at cost. Depreciation for property and equipment commences when it is put into service and are depreciated using the straight-line method over property and equipment’s estimated useful lives: Machinery & equipment 3-7 Years Office equipment & furniture 5-7 Years Computers & software 3-5 Years Vehicles & trailers 3-7 Years Leasehold improvements 3-5 Years Depreciation and amortization expense for the years ended December 31, 2020 and 2019 was $337 and $353, respectively.
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating lease right-of-use assets (“ROU assets”) and short-term and long-term lease liabilities are included on the face of the consolidated balance sheet. If the Company had finance lease ROU assets, such assets would be presented within other assets, and finance lease liabilities would be presented appropriately within liabilities. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, the Company uses an incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating lease ROU asset also excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are accounted for as a single lease component. For lease agreements with terms less than 12 months, the Company has elected the short-term lease measurement and recognition exemption, and the Company recognizes such lease payments on a straight-line basis over the lease term.
Warranty Liability	Warranty Liability The Company establishes warranty liability reserves to provide for estimated future expenses as a result of installation, product and performance defects, product recalls and litigation incidental to the Company’s business. Liability estimates are determined based on management’s judgment, considering such factors as historical experience, the likely current cost of corrective action, manufacturers’ and subcontractors’ participation in sharing the cost of corrective action, and consultations with third party experts such as engineers. Solar panel manufacturers currently provide substantial warranties of between ten to twenty-five years with full reimbursement to replace and install replacement panels. Inverter manufacturers currently provide warranties covering ten to fifteen years including replacement and installation. The warranty liability for estimated future warranty costs at December 31, 2020 and 2019 is $1,131 and $441, respectively.
Advertising and Marketing	Advertising and Marketing The Company expenses advertising and marketing costs as incurred. Advertising and marketing costs may include printed material, billboards, sponsorships, direct mail, radio, telemarketing, tradeshow costs, magazine, and catalog advertisement. Advertising and marketing costs for the years ended December 31, 2020 and 2019 were $107 and $123, respectively.
Stock-Based Compensation	Stock-Based Compensation The Company periodically issues stock options and warrants to employees and non-employees. The Company accounts for stock option and warrant grants issued and vesting to employees based on the authoritative guidance provided by the Financial Accounting Standards Board (“FASB”) whereas the value of the award is measured on the date of grant and recognized over the vesting period. The Company accounts for stock option and warrant grants issued and vesting to non-employees in accordance with the authoritative guidance of the FASB whereas the value of the stock compensation is based upon the measurement date as determined at either a) the date at which a performance commitment is reached, or b) at the date at which the necessary performance to earn the equity instruments is complete. Non-employee stock-based compensation charges generally are amortized over the vesting period on a straight-line basis. In certain circumstances where there are no future performance requirements by the non-employee, option grants are immediately vested and the total stock-based compensation charge is recorded in the period of the measurement date.
Basic and Diluted Net (Loss) Per Share Calculations	Basic and Diluted Net (Loss) per Share Calculations (Loss) per Share dictates the calculation of basic earnings (loss) per share and diluted earnings per share. Basic earnings (loss) per share are computed by dividing income (loss) available to common shareholders by the weighted-average number of common shares available. Diluted earnings per share is computed similar to basic earnings per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. The shares for employee options, restricted stock, warrants and convertible notes were not used in the calculation of the net loss per share. A net loss causes all outstanding common stock options to be anti-dilutive. As a result, the basic and diluted losses per common share are the same for the year ended December 31, 2020 and 2019. As of December 31, 2020, the potentially dilutive securities were excluded from the computations of weighted average shares outstanding including 88,441 stock options. As of December 31, 2019, the potentially dilutive securities were excluded from the computations of weighted average shares outstanding including 143,623 stock options, 5,952 restricted stock grants, 428,143 warrants. Dilutive per share amounts are computed using the weighted-average number of common shares outstanding and potentially dilutive securities, using the treasury stock method, if their effect would be dilutive.
Long-Lived Assets	Long-Lived Assets The Company reviews its property and equipment and any identifiable intangibles for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The test for impairment is required to be performed by management at least annually. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted operating cash flow expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.
Goodwill	Goodwill The Company accounts for business combinations under the acquisition method of accounting in accordance with ASC 805, “Business Combinations,” where the total purchase price is allocated to the tangible and identified intangible assets acquired and liabilities assumed based on their estimated fair values. The purchase price is allocated using the information currently available, and may be adjusted, up to one year from acquisition date, after obtaining more information regarding, among other things, asset valuations, liabilities assumed and revisions to preliminary estimates. The purchase price in excess of the fair value of the tangible and identified intangible assets acquired less liabilities assumed is recognized as goodwill. The Company retains a valuation consulting firm to test for goodwill impairment in the fourth quarter of each year and whenever events or circumstances indicate that the carrying amount of an asset exceeds its fair value and may not be recoverable. In accordance with the Company’s policies, the Company performed a quantitative assessment of goodwill at December 31, 2019 and no impairment was found. As a result of the events and circumstances resulting from the COVID-19 pandemic, the Company’s outlook for revenue, profitability and cash flow had deteriorated. Therefore, the Company performed another quantitative assessment of goodwill at March 31, 2020, where it was determined that the carrying value of goodwill exceeded its fair value at March 31, 2020. As a result, the Company recorded an impairment of $4,000. The Company performed another quantitative assessment of goodwill at December 31, 2020 and no additional impairment was found.
Fair Value of Financial Instruments	Fair Value of Financial Instruments Disclosures about fair value of financial instruments, requires disclosure of the fair value information, whether or not recognized in the balance sheet, where it is practicable to estimate that value. As of December 31, 2020, the amounts reported for cash, accrued interest and other expenses, and notes payable approximate the fair value because of their short maturities. The Company accounts for financial instruments measured as fair value on a recurring basis under ASC Topic 820. ASC Topic 820 defines fair value, established a framework for measuring fair value in accordance with accounting principles generally accepted in the United States and expands disclosures about fair value measurements. 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. ASC Topic 820 established a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). These tiers include: ● Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; ● Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and ● Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
Income Taxes	Income Taxes The Company uses the liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to financial statements carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. The measurement of deferred tax assets and liabilities is based on provisions of applicable tax law. The measurement of deferred tax assets is reduced, if necessary, by a valuation allowance based on the amount of tax benefits that, based on available evidence, is not expected to be realized.
Reclassifications	Reclassifications Certain reclassifications have been made to prior year’s financial statement to conform to classifications used in the current year.
Segment Reporting	Segment Reporting Operating segments are defined as components of an enterprise for which separate financial information is available and evaluated regularly by the chief operating decision maker, or decision-making group, in deciding the method to allocate resources and assess performance. The Company currently has one reportable segment for financial reporting purposes, which represents the Company’s core business.
New Accounting Pronouncements	New Accounting Pronouncements Adopted Accounting Pronouncements In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment, which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, U.S. GAAP requires the performance of procedures to determine the fair value at the impairment testing date of assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, the amendments under this ASU require the goodwill impairment test to be performed by comparing the fair value of a reporting unit with its carrying amount. An impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The ASU became effective for the Company on January 1, 2020 and was followed in the preparation of a quantitative assessment of goodwill at March 31, 2020, where it was determined that the carrying value of goodwill exceeded its fair value at March 31, 2020. As a result, we recorded an impairment of $4,000. The quantitative assessment performed at December 31, 2020 determined that there was no additional impairment. Management reviewed currently issued pronouncements during the year ended December 31, 2020, and believes that any other recently issued, but not yet effective, accounting standards, if currently adopted, would not have a material effect on the accompanying consolidated financial statements.
Revision of 2019 Amounts Previously Reported	Revision of 2019 Amounts Previously Reported In the preparation of this Annual Report on Form 10-K for the year ended December 31, 2020, the Company determined that it had omitted to record a deemed dividend on the repricing of warrants it issued in 2015. The 2019 sales of common stock pursuant to an “at the market offering” triggered down round provisions associated with 428,143 warrants that resulted in an understatement of the net loss attributable to common shareholders and loss per share attributable to common shareholders for the year ended December 31, 2019. The warrants expired unexercised in March 2020 (see Note 12). The Company assessed the materiality of this misstatement in accordance with Staff Accounting Bulletin No. 108 – “Qualifying Misstatements” and concluded this error was not qualitatively material as there was no impact on the consolidated balance sheet, statement of shareholders’ equity, statement of cash flows and statement of operations other than the net loss available to common shareholders. As such, the correction of the error is only revised in the December 31, 2019 consolidated statement of operations presented herein. The effect of this revision on the line items within the statement of operations for the year ended December 31, 2019 was as follows: For the Year Ended December 31, 2019 As previously Adjustment As revised Consolidated Statement of Operations Net Loss $ (9,186 ) $ - $ (9,186 ) Deemed dividend on repricing of warrants $ - $ (1,430 ) $ (1,430 ) Net Loss available to common shareholders $ (9,186 ) $ (1,430 ) $ (10,616 ) Net Loss per common share, basic and diluted $ (2.07 ) $ (0.32 ) $ (2.39 )
