13. COMMITMENTS AND CONTINGENCIES  The Company continuously evaluates contingencies based upon the best available evidence.  The Company believes that allowances for loss have been provided to the extent necessary and that its assessment of contingencies is reasonable. To the extent that resolution of contingencies results in amounts that vary from the Companys estimates, future earnings will be charged or credited.  The principal contingencies are described below:  Insurance  The Companys workers compensation risks are self-insured in most states. In addition, other workers compensation risks and certain levels of insured general liability risks are based on retrospective premium plans, deductible plans, and self-insured retention plans. The liability for workers compensation risks is accounted for on a present value basis. Actual claim settlements and expenses incident thereto may differ from the provisions for loss. Property risks have been underwritten by a subsidiary and are all reinsured with unrelated insurance companies. Operating divisions and subsidiaries have paid premiums, and the insurance subsidiary has provided loss allowances, based upon actuarially determined estimates.  Litigation  Various claims and lawsuits arising in the normal course of business, including suits charging violations of certain antitrust, wage and hour, or civil rights laws, as well as product liability cases, are pending against the Company. Some of these suits purport or have been determined to be class actions and/or seek substantial damages. Any damages that may be awarded in antitrust cases will be automatically trebled. Although it is not possible at this time to evaluate the merits of all of these claims and lawsuits, nor their likelihood of success, the Company is of the belief that any resulting liability will not have a material effect on the Companys financial position, results of operations, or cash flows.  The Company continually evaluates its exposure to loss contingencies arising from pending or threatened litigation and believes it has made provisions where it is reasonably possible to estimate and when an adverse outcome is probable. Nonetheless, assessing and predicting the outcomes of these matters involves substantial uncertainties. Management currently believes that the aggregate range of loss for the Companys exposure is not material to the Company. It remains possible that despite managements current belief, material differences in actual outcomes or changes in managements evaluation or predictions could arise that could have a material adverse effect on the Companys financial condition, results of operations, or cash flows.  Assignments  The Company is contingently liable for leases that have been assigned to various third parties in connection with facility closings and dispositions. The Company could be required to satisfy the obligations under the leases if any of the assignees is unable to fulfill its lease obligations. Due to the wide distribution of the Companys assignments among third parties, and various other remedies available, the Company believes the likelihood that it will be required to assume a material amount of these obligations is remote.
