(a) The parent corporation ratios include the accounts of Mellon Financial Corporation; Mellon Funding Corporation, a wholly owned subsidiary of Mellon that functions as a financing entity for Mellon and its subsidiaries by issuing commercial paper and other debt guaranteed by Mellon; and MIPA, LLC, a single member limited liability company wholly owned by Mellon, created to hold and administer corporate owned life insurance. Because these ratios exclude from earnings the equity in undistributed net income (loss) of subsidiaries, these ratios vary with the payment of dividends by such subsidiaries.
