Accounting Policies [Abstract]  
Basis of Presentation BASIS OF PRESENTATION
The accompanying condensed consolidated financial statements of Ameresco, Inc. (including its subsidiaries, the “Company,” “Ameresco,” “we,” “our,” or “us”) are unaudited, according to certain rules and regulations of the Securities and Exchange Commission, and include, in our opinion, normal recurring adjustments necessary for a fair presentation in conformity with accounting principles generally accepted in the United States (“GAAP”) of the results for the periods indicated.
Reclassification and Rounding
Reclassification and Rounding
Certain prior period amounts were reclassified to conform to the presentation in the current period. We round amounts in the condensed consolidated financial statements to thousands and calculate all percentages and per-share data from the underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot, or recalculate based on reported numbers due to rounding.
Accounts Receivable Factoring
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 months ended March 31, 2024 and 2023 were $169 and $0, respectively, and are included in other expense, net in the condensed consolidated statements of income.
Prepaid Expenses and Other Current Assets
Prepaid Expenses and Other Current Assets
Prepaid expenses and other current assets consist primarily of other receivables, deferred project costs, and other short-term prepaid expenditures that will be expensed within one year.

Recent Accounting Pronouncements

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 consolidated financial statements.
Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative
In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative, which updates the disclosure or presentation requirements for a variety of topics in the codification. ASU 2023-06 is effective from the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K, with early adoption prohibited. We will monitor the removal of the requirements from the current regulations and adopt the related amendments, but we do not anticipate this new guidance will have a material impact on our condensed consolidated financial statements as we are currently subject to SEC requirements.
Segment Reporting (Topic 820) - Improvements to Reportable Segment Disclosures
In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 820) - Improvements to Reportable Segment Disclosures, which improves reportable segment disclosures by requiring enhanced disclosures for significant segment expenses and other segment items. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
Income Taxes (Topic 740) - Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance the income tax disclosures, including disaggregation of information in the rate reconciliation table and disaggregated information related to income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
Compensation—Stock Compensation (Topic 718) - Scope Application of Profits Interest and Similar Awards
In March 2024, the FASB issued ASU 2024-01, Compensation—Stock Compensation (Topic 718) - Scope Application of Profits Interest and Similar Awards, to clarify how to determine if a profits interest or similar award is within the scope of ASC 718 or is not a share-based payment arrangement and is within the scope of other guidance. ASU 2024-01 is effective for fiscal years
beginning after December 15, 2024. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
Codification Improvements—Amendments to Remove References to the Concepts Statements
In March 2024, the FASB issued ASU 2024-02, Codification Improvements—Amendments to Remove References to the Concepts Statements, to remove references to various FASB Concepts Statements based on suggestions received from stakeholders on the Accounting Standards Codification and other incremental improvements to GAAP. ASU 2024-02 is effective for fiscal years beginning after December 15, 2024. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
