Covid-19	(6) COVID-19 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 is considered an essential and critical business by the U.S. Department of Homeland Security’s Cyber and Infrastructure Security Agency (CISA) and will continue to operate under state of emergency and shelter in place orders issued in various jurisdictions across the country. Management has made a variety of efforts seeking to ensure the ongoing availability of Saia’s transportation services, while instituting actions and policies to help safeguard employees and customers from COVID-19, including limiting physical employee and customer contact, implementing enhanced cleaning and hygiene protocols at Saia’s facilities, and instituting telecommuting where possible. Through the date of this filing, the Company has not experienced significant disruptions in the Company’s LTL network operations. The Company’s consolidated financial statements reflect estimates and assumptions made by management that affect the reported amounts of assets and liabilities. The Company has considered the impact of COVID-19 on the assumptions and estimates used and determined that there were no material adverse impacts on the Company’s first quarter 2021 financial position. It is possible that these assumptions and estimates may materially change in the future. 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. On March 11, 2021, the American Rescue Plan Act of 2021 was signed into law and provides further economic relief and stimulus to deal with the economic impact of the COVID-19 pandemic. The company continues to monitor any effects that may result from these Acts and other similar legislation or actions in geographies in which our business operates, however the Company does not believe it will be able to take advantage of the provisions of the CARES Act.
