The Company has consistently applied the accounting policies to all periods presented in these condensed consolidated financial statements.

In August 2020, the FASB issued Accounting Standards Update (“ASU”)ASU No. 2020-06,2020-06: Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06)2020-06”). ASU 2020-06 simplifies the accounting for convertible debt and convertible preferred stock by removing the requirements to separately present certain conversion features in equity. In addition, the amendments in the ASU also simplify the guidance in ASC 815-40, Derivatives and Hedging: Contracts in Entity’s Own Equity, by removing certain criteria that must be satisfied in order to classify a contract as equity, which is expected to decrease the number of freestanding instruments and embedded derivatives accounted for as assets or liabilities. Finally, the amendments revise the guidance on calculating earnings per share, requiring use of the if-converted method for all convertible instruments and rescinding an entity’s ability to rebut the presumption of share settlement for instruments that may be settled in cash or other assets. The new standard isbecame effective for the Company for annual periods beginning December 15, 2021. The Company adopted this ASU as of January 1, 2022 using a modified retrospective method of transition, which did not have an impact on its condensed consolidated financial statements and related disclosures.

The Company considers the applicability and impact of all ASUs. ASUs not referenced below were assessed and determined to be either not applicable or are not expected to have a material impact on the Company’s consolidated financial statements.

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which amends ASC 805 to add contract assets and contract liabilities to the list of exceptions to the recognition and measurement principles that apply to business combinations and to require that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years and should be applied prospectively to business combinations occurring on or after the effective date of the amendments. Early adoption of the amendments is permitted, including adoption in an interim period. The Company is currently evaluating the impact of the adoption of this ASU on the Company’s consolidated financial statements.

To reduce credit risk, the Company considers customer creditworthiness, past transaction history with the customer, current economic industry trends, and changes in customer payment terms when determining the collectability of specific customer accounts. Past due balances over 90 days and other higher risk amounts are reviewed individually for collectability. Based on management’s assessment, the Company provides for estimated uncollectible amounts through a charge to earnings and a credit to valuation allowance. Balances that remain outstanding after the Company has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable.

On March 31,As of September 30, 2022 the Company’s Level 3 liabilities consisted of the Private Placement warrant liability. The determination of the fair value of warrant liability is discussed in Note 6.

The following table provides information by level for the Company’s assets and liabilities that were measured at fair value on a recurring basis (in thousands):

Money market funds are included within Level 1 of the fair value hierarchy because they are valued using quoted market prices.

The fair value of the redeemable convertible preferred stock warrant, redeemable convertible preferred stock tranche and Private Placement warrant liabilities is based on significant unobservable inputs, which represent Level 3 measurements within the fair value hierarchy. In determining the fair value of the warrant liabilities, the Company used the Black-Scholes option pricing model to estimate the fair value using unobservable inputs, including the expected term, expected volatility, risk-free interest rate and dividend yield (see Note 6).
