|(a) | The parent corporation ratios include the accounts of Mellon Financial Corporation (the Corporation); Mellon Funding Corporation, a wholly owned subsidiary of the
Corporation that functions as a financing entity for the Corporation and its subsidiaries by issuing commercial paper and other debt guaranteed by the Corporation; and MIPA, LLC, a single member limited liability company wholly owned by the
Corporation, 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.
