Accounting Policies [Abstract]  
Consolidation, Policy
The Consolidated Financial Statements include the accounts of the Corporation and its majority-owned subsidiaries, and those variable interest entities (VIEs) where the Corporation is the primary beneficiary. Intercompany accounts and transactions have been eliminated. Results of operations of acquired companies are included from the dates of acquisition and for VIEs, from the dates that the Corporation became the primary beneficiary. Assets held in an agency or fiduciary capacity are not included in the Consolidated Financial Statements. The Corporation accounts for investments in companies for which it owns a voting interest and for which it has the ability to exercise significant influence over operating and financing decisions using the equity method of accounting or at fair value under the fair value option. These investments are included in other assets. Equity method investments are subject to impairment testing and the Corporation's proportionate share of income or loss is included in equity investment income.
Basis of Accounting, Policy
The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect reported amounts and disclosures. Realized results could differ from those estimates and assumptions.

These unaudited Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements of the Corporation's 2012 Annual Report on Form 10-K. The nature of the Corporation's business is such that the results of any interim period are not necessarily indicative of results for a full year. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim period results have been made. The Corporation evaluates subsequent events through the date of filing with the Securities and Exchange Commission (SEC). Certain prior-period amounts have been reclassified to conform to current period presentation.
New Accounting Pronouncements, Policy
In December 2012, the Financial Accounting Standards Board (FASB) issued a proposed standard on accounting for expected credit losses. It would replace multiple existing impairment models, including an "incurred loss" model for loans, with an "expected credit loss" model. The FASB announced it would establish the effective date when it issues the final standard. The Corporation cannot predict at this time whether or when a final standard will be issued, when it will be effective or what its final provisions will be. It is possible that the final standard could have a material adverse impact on the Corporation's results of operations if and when it is issued and becomes effective.
