(1) Certain prior-period information has been reclassified to conform to the current year’s presentation.

(2) Income before income taxes does not include losses from unconsolidated investees, dividends on preferred securities subject to mandatory redemption, (loss)/gain on discontinued operations and cumulative effect of accounting change, net.

“Earnings” consist of income before losses from unconsolidated investees, income taxes, (loss)/gain on discontinued operations, cumulative effect of accounting change and fixed charges, less dividends on preferred securities subject to mandatory redemption.

“Fixed charges” consist of interest cost, including interest on deposits, dividends on preferred securities subject to mandatory redemption, and that portion of rent expense estimated to be representative of the interest factor.

The preferred stock dividend amounts represent pre-tax earnings required to cover dividends on preferred stock.
