	us-gaap	Use Of Estimates UseOfEstimates	In preparing financial statements in conformity with U.S. GAAP, estimates and assumptions are made that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and the reported amounts of revenues and expenses. Actual results could differ from those estimates. Significant estimates are used in determining, but are not limited to, the Company’s allowance for doubtful accounts, accrued insurance claims, valuations, deferred taxes and reviews for potential impairment. The estimates are based upon various factors including current and historical trends, as well as other pertinent industry and regulatory authority information, including the potential future effects of COVID-19. Management regularly evaluates this information to determine if it is necessary to update the basis for its estimates and to adjust for known changes.

The Company expects to recognize revenue on approximately 41.3% of the remaining performance obligations over the next 12 months, with the balance to be recognized thereafter. These amounts exclude variable consideration primarily related to performance obligations that consist of a series of distinct service periods with revenues based on future performance that cannot be estimated at contract inception. The Company also has elected to apply the practical expedient that permits exclusion of information about the remaining performance obligations with original expected durations of one year or less.
