Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company records income tax expense during interim periods based on its best estimate of the full year’s tax rate. Certain items are given discrete period treatment and, as a result, the tax effects of such items are reported in full in the relevant interim period. The Company’s tax rate was 37.4% for the three months ended March 31, 2014 compared to 35.2% for the three months ended March 31, 2013. The Company's tax rate for the three months ended March 31, 2014 was higher than the statutory federal income tax rate of 35% primarily attributable to state income taxes and changes in unrecognized tax benefits, partially offset by dividends received deductions and foreign tax credits. The Company's tax rate for the three months ended March 31, 2013 was higher than the statutory federal income tax rate of 35% primarily attributable to state income taxes and changes in unrecognized tax benefits, partially offset by dividends received deductions, foreign tax credits and research and experimentation credits. The full year 2014 tax rate can be affected as a result of variances among the estimates and amounts of full year sources of taxable income (e.g., domestic consolidated, joint venture and/or international), the realization of tax credits (e.g., historic rehabilitation, research and experimentation, foreign tax and state incentive), adjustments which may arise from the resolution of tax matters under review and the Company’s assessment of its liability for uncertain tax positions.
