Income Taxes	6 Months Ended
Jun. 30, 2016
Income Taxes [Abstract]
Income Taxes	Note 14 ― Income Taxes A. Income Tax Expense The consolidated effective tax rates of 37.7% for the six months ended June 30, 2016 and 2015 reflect the health insurance industry tax that is not deductible for federal income tax purposes. The effective tax rate for 2016 also reflects tax benefits associated with adopting ASU 2016-09 effective January 1, 2016 as described in Note 2, partially offset by the impact of certain costs related to the pending Anthem transaction that are not tax deductible. As part of its global capital management strategy, the Company's foreign operations retain a significant portion of their earnings overseas. These undistributed earnings are deployed outside of the U.S. in support of the liquidity and capital needs 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. The Company has accumulated undistributed foreign earnings of $2.5 billion as of June 30, 2016. If the Company intended to repatriate these foreign earnings to the U.S., the Company's consolidated balance sheet would have included an additional $350 million of deferred tax liabilities as of June 30, 2016. B. Unrecognized Tax Benefits Changes in unrecognized tax benefits were immaterial for the six months ended June 30, 2016. C. Other Tax Matters The Internal Revenue Service (“IRS”) is expected to complete their examination of the Company's 2011 and 2012 consolidated federal income tax returns during the second half of 2016.

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.
