Fixed charges consist of interest, expensed or capitalized, on borrowings (including or excluding deposits, as applicable), and the portion of rental expense which is deemed representative of interest. The preferred stock dividend requirements represent the pretax earnings which would have been required to cover such dividend requirements on the Corporation's preferred stock outstanding.
