The CARES Act provides a substantial stimulus and assistance package intended to address the impact of the COVID-19 pandemic, including tax relief and government loans, grants and investments. On December 27, 2020, an additional stimulus was approved as part of the Consolidated Appropriations Act, 2021 (CAA). Many of the more recent coronavirus relief provisions are extensions and modifications of CARES Act provisions. The CARES Act and CAA had no impact on our consolidated financial statements for the year ended December 31, 2020. We continue to monitor any effects that may result from the CARES Act, CAA, and other similar legislation or governmental actions in geographies in which our business operates.

The amendments in this update are applicable to contract modifications that replace a reference LIBOR rate beginning on March 12, 2020 through December 31, 2022. The optional expedients apply to our Credit Agreement and allow the Company to account for modifications due to reference rate reform by prospectively adjusting the effective interest rate on the Credit Agreement. As of December 31, 2020, we have not modified the Credit Agreement related to reference rate reform. We plan to apply the optional practical expedients and exceptions to modifications of the Credit Agreement affected by reference rate reform and are evaluating the effect on our consolidated financial statements, related disclosures, and results of operations.</span></div>
