SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Our accounting policies are set forth in Note 2 to the consolidated financial statements contained in our 2022 Form 10-K. We have included certain updates to those policies below.
Accounts Receivable and Allowance for Credit Losses
Changes in the allowance for credit losses are as follows:
Three Months Ended September 30, Nine Months Ended September 30,
2023 2022 2023 2022
Allowance for credit losses, beginning of period $ 903  $ 2,262  $ 911  $ 2,263

Account write-offs and other (64) (19) (651) (264)
Allowance for credit losses, end of period $ 897  $ 2,362  $ 897  $ 2,362 
Accounts Receivable Factoring
Ameresco’s wholly-owned subsidiary in Italy entered into factoring agreements to sell certain receivables to unrelated third-party financial institutions on a non-recourse basis. These transactions are accounted for in accordance with ASC Topic 860, Transfers and Servicing and result in a reduction in accounts receivable because the agreements transfer effective control over the
receivables, and related risk, to the buyers. Our Italian subsidiary does not retain any interest in the underlying accounts receivable once sold. Trade accounts receivables balances sold are removed from the condensed consolidated balance sheets, and cash received is reflected in operating activities in the condensed consolidated statements of cash flows. Factoring fees during the three and nine months ended September 30, 2023 were $2,075 and $3,326, respectively, and are included in other expense, net in the condensed consolidated statements of income. See Note 18. Other Expenses, Net.
Recent Accounting Pronouncements
Reference Rate Reform
In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04, as amended by ASU 2021-01 in January 2021, directly addressing the effects of reference rate reform on financial reporting as a result of the cessation of the publication of certain London interbank offered rate (“LIBOR”) rates beginning December 31, 2021, with complete elimination of the publication of the LIBOR rates by June 30, 2023. The guidance provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform by virtue of referencing LIBOR or another reference rate expected to be discontinued. This guidance became effective on March 12, 2020, and then amended by ASU 2022-06 in December 2022, extending the adoption date to no later than December 31, 2024, with early adoption permitted. We adopted this guidance beginning January 1, 2023 upon entering amendments to credit agreements which introduced the secured overnight financing rate as administrated by the Federal Reserve Bank of New York to replace LIBOR as the benchmark. The adoption of this guidance did not have a material impact on our condensed consolidated financial statements.
Derivatives and Hedging
In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method, which expands the current single-layer method to allow multiple hedged layers of a single closed portfolio to be hedged under the method. ASU 2022-01 is effective for our fiscal year ending beginning after December 15, 2022. We adopted this accounting standard as of January 1, 2023 and the adoption did not have an impact on our condensed consolidated financial statements.
Fair Value Measurement
In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, which clarifies the measurement criteria for equity securities and refines the disclosure requirements for equity securities subject to contractual sale restrictions. ASU 2022-03 is effective for our fiscal year ending beginning after December 15, 2023. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
Investments - Equity Method and Joint Ventures
In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, which defines consistent accounting for equity investments for the purpose of receiving income tax credits and other income tax benefits. ASU 2023-02 is effective for our fiscal year ending beginning after December 15, 2023. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
Business Combinations— Joint Venture Formations
In August 2023, the FASB issued ASU 2023-05, Business Combinations— Joint Venture Formations (Subtopic 805-60) Recognition and Initial Measurement, which addresses the accounting for contributions made to a joint venture, upon formation, in a joint venture’s separate financial statements. ASU 2023-05 is effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
