Notes to Financial Statements [Abstract]
Employee Stock Ownership Plan	Employee Stock Ownership Plan In 1989, the Company expanded its Employee Stock Ownership Plan (ESOP) through the introduction of a leveraged ESOP that funds certain benefits for employees who have met eligibility requirements. The ESOP issued $410 of long-term notes due through July 2009 bearing an average interest rate of 8.7%. The notes, which were guaranteed by the Company, were repaid in July 2009. The ESOP used the proceeds from the notes issuance to purchase 6,315,149 shares of Preference stock from the Company. The Preference stock, each share of which was convertible into eight shares of common stock, had a redemption price of $65 per share and paid semiannual dividends equal to the higher of $2.44 or the current dividend paid on eight common shares for the comparable six-month period. As a result of rules issued by the IRS related to employer stock held in defined contribution plans, the Company issued a notice of redemption with respect to the 2,405,192 shares of Preference stock outstanding on December 29, 2010. At the direction of the Company’s ESOP trustee, the shares of Preference stock were converted into 19,241,536 shares of common stock. The common stock for the conversion was issued from treasury shares, see Note 7. During 2000, the ESOP entered into a loan agreement with the Company under which the benefits of the ESOP may be extended through 2035. Advances from the Company of $60 remain outstanding at December 31, 2011. Dividends on stock held by the ESOP, are paid to the ESOP trust and, together with cash contributions and advances from the Company, are used by the ESOP to repay principal and interest. Stock is allocated to participants based upon the ratio of the current year’s debt service to the sum of total principal and interest payments over the life of the debt. As of December 31, 2011, 10,304,813 common shares were released and allocated to participant accounts and 6,797,192 common shares were available for future allocation to participant accounts. Dividends on the stock are deductible for income tax purposes and, accordingly, are reflected net of their tax benefit in the Consolidated Statements of Changes in Shareholders’ Equity. Annual expense related to the leveraged ESOP, determined as interest incurred on the original notes, plus the higher of either principal payments or the historical cost of Preference stock allocated, less dividends received on the shares held by the ESOP and advances from the Company, was $0 in 2011, $6 in 2010 and $22 in 2009. Unearned compensation, which is shown as a reduction in Shareholders’ equity, is the amount of ESOP debt due to the Company. Interest incurred on the ESOP notes was $0 in 2011 and 2010, and $2 in 2009. The Company paid dividends on the shares held by the ESOP of $42 in 2011, $41 in 2010 and $37 in 2009. Company contributions to the ESOP were $0 in 2011, $6 in 2010 and $22 in 2009.

Tabular disclosure of the description of the plan, the basis for determining contributions, including the employee groups covered, and the nature and effect of significant matters affecting comparability of information for all periods presented. For leveraged ESOPs and pension reversion ESOPs, the disclosure may include the basis for releasing shares and how dividends on allocated and unallocated shares are used. Disclosure may also include a description of the accounting policies followed for ESOP transactions, including the method of measuring compensation, the classification of dividends on ESOP shares, and the treatment of ESOP shares for EPS computations. If the employer has both old ESOP shares for which it does not adopt the latest guidance and new ESOP shares for which the new guidance is required, the accounting policies for both blocks of shares may be described. Disclosure may also include he amount of compensation cost recognized during the period, the number of allocated shares, committed-to-be-released shares, and suspense shares held by the ESOP at the balance-sheet date, the fair value of unearned ESOP shares at the balance-sheet date for shares accounted for under the latest guidance, the existence and nature of any repurchase obligation, including disclosure of the fair value of the shares allocated as of the balance sheet date, which are subject to a repurchase obligation.
