Shareholders' Equity [Abstract]
Shareholders' Equity	15. Shareholders’ Equity Comprehensive Capital Plan In November 2010, the Federal Reserve issued Revised Temporary Addendum to Supervisory Letter SR 09-4. This letter outlines specific criteria the Federal Reserve will consider when evaluating proposed capital actions by the 19 largest U.S. banking institutions that participated in the SCAP, including KeyCorp. These include actions such as increasing dividends, implementing common stock repurchase programs, or redeeming or repurchasing capital instruments more broadly. The Federal Reserve is required to assess the capital adequacy of the nineteen largest BHCs based upon a review of each BHC’s comprehensive capital plan. On January 7, 2011, we submitted our comprehensive capital plan to the Federal Reserve. On March 18, 2011, the Federal Reserve informed us that it had no objections to the capital actions set forth in our Comprehensive Capital Plan following its Comprehensive Capital Analysis and Review (“CCAR”). On June 10, 2011, we submitted to the Federal Reserve and provided to the OCC an updated Comprehensive Capital Plan, which set forth additional capital actions related to redemptions of certain outstanding capital securities. On August 1, 2011, the Federal Reserve informed us that it had no objections to the capital actions set forth in our updated capital plan. Repurchase of TARP CPP Preferred Stock, Warrant and Completion of Equity and Debt Offerings As previously reported, Key completed the repurchase of the $2.5 billion of Series B Preferred Stock and corresponding warrant issued to the U.S. Treasury Department. As a result of the repurchase, we recorded a $49 million one-time deemed dividend in the first quarter of 2011 related to the remaining difference between the repurchase price and the carrying value of the preferred shares at the time of repurchase. Beginning with the second quarter of 2011, the repurchase resulted in the elimination of quarterly dividends of $31 million and discount amortization of $4 million, or $140 million on an annual basis, related to these preferred shares. In total, Key paid $2.867 billion to the U.S. Treasury during the investment period in the form of dividends, principal and repurchase of the warrant, resulting in a return to the U.S. Treasury of $367 million above the initial investment of $2.5 billion on November 14, 2008. Cumulative Effect Adjustment (after-tax) Effective January 1, 2010, we adopted new consolidation accounting guidance. As a result of adopting this new guidance, we consolidated our education loan securitization trusts (classified as discontinued assets and liabilities). That consolidation added $2.8 billion in assets, and liabilities and equity to our balance sheet and resulted in a cumulative effect adjustment (after-tax) of $45 million to beginning retained earnings on January 1, 2010. Additional information regarding the consolidation of these education loan securitization trusts is provided in Note 9 (“Variable Interest Entities”) and Note 11 (“Divestiture and Discontinued Operations”).
