Income Taxes	3 Months Ended
Mar. 31, 2017
Income Taxes [Abstract]
Income Taxes	Note 15 ― Income Taxes A. Income Tax Expense The consolidated effective tax rate decreased to 33.4% for the three months ended March 31, 2017 compared with 37.2% for the three months ended 2016 due to the moratorium in 2017 on the health insurance industry tax that is not deductible for federal income tax purposes. The Company maintains a capital management strategy to retain overseas a significant portion of the earnings from its foreign operations. As of March 31, 2017, undistributed earnings were approximately $2.7 billion. These undistributed earnings are deployed outside of the U.S. predominantly in support of the liquidity and regulatory capital requirements of our foreign operations. The Company does not intend to repatriate these earnings to the U.S. and as a result, income taxes are provided using the respective foreign jurisdictions' tax rate. If the Company had intended to repatriate these foreign earnings to the U.S., the Company's Consolidated Balance Sheets would have included an additional $362 million of deferred tax liabilities as of March 31, 2017. B. Unrecognized Tax Benefits Changes in unrecognized tax benefits were immaterial for the three months ended March 31, 2017.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.
