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, 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. Management regularly evaluates this information to determine if it is necessary to update the basis for its estimates and to adjust for known changes.</span></div>
