In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326), which requires entities to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost. ASU No. 2016-13 is effective for smaller reporting companies for annual reporting periods beginning after December 15, 2022, including interim periods within those annual reporting periods, with early adoption permitted. The Company is currently evaluating the impact of the new standard on its consolidated financial statements and related disclosures.

Debt with Conversion and Other Options and Derivatives and Hedging

In August 2020, the FASB issued ASU No. 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. The amendments in ASU No. 2020-06 simplify the complexity associated with applying U.S. GAAP for certain financial instruments with characteristics of liabilities and equity. More specifically, the amendments focus on the guidance for convertible instruments and derivative scope exceptions for contracts in an entity’s own equity.

Business Combinations

In October 2021, the FASB issued ASU No. 2021-08, Business Combinations (Topic 606): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires that an entity recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 as if it had originated the contracts. Generally, this should result in an acquirer recognizing and measuring the acquired contract assets and contract liabilities consistent with how they were recognized and measured in the acquiree’s financial statements, if the acquiree prepared financial statements in accordance with U.S. GAAP. The amendment in this update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The guidance should be applied prospectively to business combinations occurring on or after the effective date of the amendment in this update.
