Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies Disclosure [Text Block] | 3 – Commitments and Contingencies From time to time, the Company is involved in litigation arising out of its operations in the ordinary course of business. The Company maintains liability insurance, including product liability coverage, in amounts deemed adequate by management. To date, aggregate costs to us for claims, including product liability actions, have not been material. However, an uninsured or partially insured claim, or claim for which indemnification is not available, could have a material adverse effect on the Company’s financial condition or results of operations. The Company believes that there are no claims or litigation pending, the outcome of which could have a material adverse effect on its financial position or results of operations. However, due to the inherent uncertainty of litigation, there can be no assurance that the resolution of any particular claim or proceeding would not have a material adverse effect on the Company’s financial condition or results of operations for the fiscal period in which such resolution occurred. In May 2013, the Company entered into a Retirement and Transition Agreement with the Company's former Chairman, W. Marvin Rush, which resulted in the recognition of $10.8 million in retirement pay and benefits recorded in selling, general and administrative expense on the Consolidated Statements of Income and Comprehensive Income for the three months and six months ended June 30, 2013. The current portion of the accrual for the unpaid retirement pay and benefits of $0.9 million is a component of accrued liabilities and the long-term portion of the accrual for the unpaid retirement pay and benefits of $2.7 million is a component of other long-term liabilities in the Consolidated Balance Sheet as of June 30, 2013.
