| Commitments, Contingencies, and Guarantees              | Note H. Commitments, Contingencies and GuaranteesCommitments and ContingenciesThe Company holds an investment in a real estate joint venture.  In the normal course of business, the Company, on a joint and several basis with other unrelated insurance company shareholders, has committed to continue funding the operating deficits of this joint venture.  Additionally, the Company and the other unrelated shareholders, on a joint and several basis, have guaranteed an operating lease for an office building, which expires in 2016.  The guarantee of the operating lease is a parallel guarantee to the commitment to fund operating deficits; consequently, the separate guarantee to the lessor is not expected to be triggered as long as the joint venture continues to be funded by its shareholders which provide liquidity to make its annual lease payments.In the event that the other parties to the joint venture are unable to meet their commitments in funding the operations of this joint venture, the Company would be required to assume the obligation for the entire office building operating lease.  The Company does not believe it is likely that it will be required to do so.  However, as of September 30, 2015, the maximum potential future lease payments and other related costs that the Company could be required to pay under this guarantee, in excess of amounts already recorded, were approximately $28 million.  If the Company were required to assume the entire lease obligation, the Company would have the right to pursue reimbursement from the other shareholders and the right to all sublease revenues.Guarantees As of September 30, 2015 and December 31, 2014, the Company had recorded liabilities of $5 million related to guarantee and indemnification agreements.  Management believes that it is not likely that any future indemnity claims will be significantly greater than the amounts recorded.In the course of selling business entities and assets to third parties, the Company agreed to guarantee the performance of certain obligations of a previously owned subsidiary and to indemnify purchasers for losses arising out of breaches of representation and warranties with respect to the business entities or assets being sold, including, in certain cases, losses arising from undisclosed liabilities or certain named litigation.  Such guarantee and indemnification agreements in effect for sales of business entities, assets and third-party loans may include provisions that survive indefinitely.  As of September 30, 2015, the aggregate amount related to quantifiable guarantees was $375 million and the aggregate amount related to indemnification agreements was $260 million.  Should the Company be required to make payments under the guarantee, it would have the right to seek reimbursement in certain cases from an affiliate of the previously owned subsidiary.In addition, the Company has agreed to provide indemnification to third-party purchasers for certain losses associated with sold business entities or assets that are not limited by a contractual monetary amount.  As of September 30, 2015, the Company had outstanding unlimited indemnifications in connection with the sales of certain of its business entities or assets that included tax liabilities arising prior to a purchaser's ownership of an entity or asset, defects in title at the time of sale, employee claims arising prior to closing and in some cases losses arising from certain litigation and undisclosed liabilities.  Certain provisions of the indemnification agreements survive indefinitely while others survive until the applicable statutes of limitation expire or until the agreed-upon contract terms expire.In the normal course of business, the Company also provided guarantees, if the primary obligor fails to perform, to holders of structured settlement annuities provided by a previously owned subsidiary, which are estimated to mature through 2120.  The potential amount of future payments the Company could be required to pay under these guarantees was approximately $2.0 billion as of September 30, 2015.  The Company does not believe a payable is likely under these guarantees, as the Company is the beneficiary of a trust that must be maintained at a level that approximates the discounted reserves for these annuities. |
