Claims Liabilities [Text Block]	NOTE 8 – CLAIMS LIABILITIES We are self-insured up to certain limits for bodily injury, property damage, workers’ compensation, cargo loss and damage claims and medical benefits. Provisions are made for both the estimated liabilities for known claims as incurred and estimates for those incurred but not reported. Our self-insurance retention levels are $0.5 million for workers’ compensation claims per occurrence, $0.05 million for cargo loss and damage claims per occurrence and $1.0 million for bodily injury and property damage claims per occurrence. For medical benefits, the Company self-insures up to $0.25 million per plan participant per year with an aggregate claim exposure limit determined by our year-to-date claims experience and the number of covered lives. We are completely self-insured for physical damage to our own tractors and trailers, except that we carry catastrophic physical damage coverage to protect against natural disasters. We maintain insurance above the amounts for which we self-insure, to certain limits, with licensed insurance carriers. We have excess general, auto and employer’s liability coverage in amounts substantially exceeding minimum legal requirements. We record claims accruals at the estimated ultimate payment amounts based on information such as individual case estimates or historical claims experience. The current portion reflects the amounts of claims expected to be paid in the next twelve months. In making the estimates of ultimate payment amounts and the determinations of the current portion of each claim we rely on past experience with similar claims, negative or positive developments in the case and similar factors. We re-evaluate these estimates and determinations each reporting period based on developments that occur and new information that becomes available during the reporting period.
