Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP") and the applicable rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial information but does not include all the information and notes required by GAAP for complete financial statements. These interim unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2022. The condensed consolidated balance sheet at December 31, 2022 has been derived from the audited consolidated financial statements at that date, but does not include all disclosures, including notes, required by GAAP for complete financial statements. The significant accounting policies used in preparation of the unaudited condensed consolidated financial statements for the three and nine months ended September 30, 2023 and 2022, are consistent with those discussed in Note 2 to the audited consolidated financial statements in the Company’s 2022 Annual Report on Form 10-K and are updated below as necessary. There have been no significant changes in our significant accounting policies or critical accounting estimates since December 31, 2022. The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all adjustments of a normal recurring nature considered necessary to present fairly our financial position as of September 30, 2023, results of our operations for the three and nine months ended September 30, 2023 and 2022, changes in stockholders' equity for the three and nine months ended September 30, 2023 and 2022, and cash flows for the nine months ended September 30, 2023 and 2022. The interim results are not necessarily indicative of the results for any future interim period or for the entire year. The unaudited condensed consolidated financial statements include the accounts of Codexis, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of our unaudited condensed consolidated financial statements in conformity with GAAP requires us to make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities, equity, revenues and expenses and related disclosure of contingent assets and liabilities. We regularly assess these estimates which primarily affect revenue recognition, deferred revenue, inventories, valuation of equity investments, valuation of assets held for sale, goodwill arising out of business acquisitions, accrued liabilities, stock awards, and the valuation allowances associated with deferred tax assets. Actual results could differ from those estimates and such differences may be material to the consolidated financial statements. Impairment of Long-Lived Assets We evaluate the carrying values of long-lived assets, which include property and equipment and right-of-use assets, whenever events, changes in business circumstances or our planned use of long-lived assets indicate that their carrying amounts may not be fully recoverable or that their useful lives are no longer appropriate. If these facts and circumstances exist, we assess for recovery by comparing the carrying values of long-lived assets with the future net undiscounted cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measure by the amount by which the carrying amount of the asset exceeds the fair value of the asset. For additional information on the impairment charge recorded in the three and nine months ended September 30, 2023, see Note 7, “Balance Sheets Details” and Note 10, “Commitments and Contingencies.” Assets Held For Sale The Company classifies assets as held for sale when the following conditions are met: (i) management has committed to a plan to sell, (ii) the assets are available for immediate sale in their present condition, (iii) the Company has initiated an active program to identify a buyer, (iv) it is probable that a sale will occur within one year, (v) the assets are actively marketed for sale at a reasonable price in relation to their current fair value, and (vi) there is a low likelihood of significant changes to the plan or that the plan will be withdrawn. If all of the criteria are met as of the balance sheet date, the assets are presented separately in the consolidated balance sheet as held for sale at the lower of the carrying amount or fair value less costs to sell. The assets are then no longer depreciated or amortized while classified as held for sale. For additional information, see Note 15, “Assets Held For Sale.” Accounting Pronouncements Recently adopted accounting pronouncements or recently issued accounting pronouncements not yet adopted There were no recent accounting pronouncements or changes in accounting pronouncements during the three and nine months ended September 30, 2023, that are of significance or potential significance to us.
