Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended September 30, 2013, the income tax effective rate was 36.5%. For the three months ended September 30, 2012, the income tax effective rate was 37.6%. The decrease in the effective rate was due primarily to income attributable to the noncontrolling interest that did not increase taxes and the Company’s share of Thompsons Limited foreign joint venture earnings considered indefinitely reinvested outside the U.S. This was offset by the tax impact of costs associated with the Thompsons Limited acquisition for which there is no tax benefit. For the nine months ended September 30, 2013, the income tax effective rate was 37.7%. For the nine months ended September 30, 2012, the income tax effective rate was 37.4%. The increase in the effective rate was due primarily to a correction made with respect to the accounting for the other comprehensive income portion of the Company’s retiree health care plan liability and the Medicare Part D subsidy and the tax effects of costs associated with the Thompsons Limited acquisition for which there is no tax benefit. Offsetting these increases is income attributable to the noncontrolling interest that did not increase taxes and the Company’s share of Thompsons Limited foreign joint venture earnings considered indefinitely reinvested outside the U.S. The Company's 2013 income tax provision includes deferred tax expense of $1.4 million due to a correction of other comprehensive income related to the portion of the Company's retiree health care plan liability and the Medicare Part D subsidy. The correction related to the years 2009 through 2012 and was recorded during the first quarter of 2013. The impact of this error on amounts previously reported was determined to be immaterial to the Consolidated Financial Statements. As a result of the correction of the error, deferred income tax expense for the nine months ended September 30, 2013 increased and accumulated other comprehensive loss decreased by $1.4 million.
