(11) Use of Estimates

             We must make estimates and assumptions to prepare the consolidated condensed financial statements in conformity with U.S. generally accepted accounting principles.  These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities in the consolidated condensed financial statements and the reported amount of revenue and expenses during the reporting period.  These estimates are primarily related to insurance and claims accruals and depreciation.  Ultimate results could differ from these estimates.
