* The consolidated credit provision is equal to the actual reported provision for credit losses.
** The Federal Reserve establishes capital adequacy requirements for the Corporation, including Tier 1 capital. Tier 1 capital is comprised of common capital and certain redeemable, non-cumulative preferred stock. Average allocated capital represents average common equity Tier 1 which is defined as average Tier 1 capital excluding qualifying perpetual preferred stock and qualifying trust preferred securities. This is a non-GAAP financial measure. For segment reporting purposes, the ROCET1 reflects return on average allocated common equity Tier 1 (“CET1”). The ROCET1 for the Risk Management and Shared Services segment and the Consolidated Total is inclusive of the annualized effect of the preferred stock dividends.
