(8)   The Company uses the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the differences between financial reporting and tax bases of assets and liabilities, and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. In July 2011, the Company received satisfactory resolution of a pending tax matter which will result in a reduction in tax expense of approximately $2,400 in the third quarter of 2011. The full year 2011 effective tax rate is now expected to be approximately 36 percent.
