Unaudited Pro Forma Combined Results
The unaudited pro forma combined results of operations include the effect of the net amortization/accretion of purchase accounting fair value adjustments based on asset and liability valuations as of the acquisition date. They also reflect the receipt of $7.6 billion from the sale of preferred securities and issuance of a warrant to purchase 16.9 million shares of PNC common stock under the TARP Capital Purchase Program (See Note 19 Shareholders Equity for additional information). During 2008, National City recorded $2.4 billion of nonrecurring charges for goodwill impairments which are included in these pro forma results. These adjustments have been consistently applied to each period presented in the table above.
