Insurance Loss Reserves [Abstract]
Unpaid Claims and Claims Expenses	This liability reflects estimates of the ultimate cost of claims that have been incurred but not reported, expected development on reported claims, claims that have been reported but not yet paid (reported claims in process), and other medical care expenses and services payable that are primarily comprised of accruals for incentives and other amounts payable to health care professionals and facilities.
Future Policy Benefits	Obligations for annuities represent discounted periodic benefits to be paid to an individual or groups of individuals over their remaining lives. Other Operations' traditional insurance contracts, which are in run-off, have no premium remaining to be collected; therefore, future policy benefit reserves represent the present value of expected future policy benefits, discounted using the current discount rate, and the remaining amortizable deferred profit liability.

This liability reflects estimates of the ultimate cost of claims that have been incurred but not reported, expected development on reported claims, claims that have been reported but not yet paid (reported claims in process), and other medical care expenses and services payable that are primarily comprised of accruals for incentives and other amounts payable to health care professionals and facilities.

Future Policy Benefits

Obligations for annuities represent discounted periodic benefits to be paid to an individual or groups of individuals over their remaining lives. Other Operations' traditional insurance contracts, which are in run-off, have no premium remaining to be collected; therefore, future policy benefit reserves represent the present value of expected future policy benefits, discounted using the current discount rate, and the remaining amortizable deferred profit liability.
