Basis of Presentation BASIS OF PRESENTATION
The accompanying condensed consolidated financial statements of Ameresco, Inc. (including its subsidiaries, the “Company”) are unaudited, pursuant to certain rules and regulations of the Securities and Exchange Commission, and include, in the opinion of the Company, 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.
The results of operations for the three months ended March 31, 2020 are not necessarily indicative of results which may be expected for the full year. The December 31, 2019 consolidated balance sheet data was derived from audited financial statements, but certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted. The interim condensed consolidated financial statements, and notes thereto, should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2019, and notes thereto, included in the Company’s annual report on Form 10-K for the year ended December 31, 2019 filed with the Securities and Exchange Commission on March 4, 2020.
In March 2020, the World Health Organization categorized Coronavirus Disease 2019 (“COVID-19”) as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency.
The Company’s condensed consolidated financial statements reflect estimates and assumptions made by management that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. The Company considered the impact of COVID-19 on the assumptions and estimates used and determined that there were no material adverse impact on the Company’s first quarter 2020 results of operations.
The severity of the impact of the COVID-19 pandemic on the Company's business will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic and the extent and severity of the impact on the Company's customers, all of which are uncertain and cannot be predicted. The Company's future results of operations and liquidity could be adversely impacted by delays in payments of outstanding receivable amounts beyond normal payment terms, delays in obtaining signed customer contracts for awarded projects, supply chain disruptions and uncertain demand. As of the date of issuance of these condensed consolidated financial statements, the extent to which the COVID-19 pandemic may materially impact the Company's financial condition, liquidity, or results of operations is uncertain.
On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) which includes modifications to the limitation on business interest expense and net operating loss provisions, and provides a payment delay of employer payroll taxes during 2020 after the date of enactment. The Company estimates the payment of approximately $5,000 of employer payroll taxes otherwise due in 2020 will be delayed with 50% due by December 31, 2021 and the remaining 50% by December 31, 2022. The CARES Act permits net operating losses from the 2018, 2019, and 2020 tax years to be carried back to the previous five tax years (beginning with the earliest year first). The Company estimates the discrete benefit associated with the net operating loss provisions of the CARES Act to be approximately $2,000 and an estimated refund of taxes paid in prior years of approximately $1,300.
