Notes to Financial Statements
Workers Compensation Insurance and Reserves Disclosure [Text Block]	Note 6 - Workers’ Compensation Insurance and Reserves We obtain our workers’ compensation insurance through Chubb Limited and ACE American Insurance Company (collectively, “ACE”) in all states in which we operate other than monopolistic jurisdictions. The ACE policies are large deductible policies where we have primary responsibility for all claims made. ACE provides insurance for covered losses and expenses in excess of $500 thousand per incident. Under these large deductible programs we are effectively self-insured. Per our contractual agreements with ACE we must provide a collateral deposit of $ 9.2 million, which we accomplish by providing a letter of credit under our agreement with Bank of America. For workers’ compensation claims originating in the monopolistic jurisdictions of North Dakota, Ohio, Washington, and Wyoming, we pay workers’ compensation insurance premiums and obtain full coverage under mandatory state administered programs. Our liability associated with claims in these jurisdictions is limited to premium payments based upon the amount of payroll paid, or hours worked, within each jurisdiction. Accordingly, our consolidated financial statements reflect only the mandated workers’ compensation insurance premium liability for workers’ compensation claims in these jurisdictions.
