OPTIONS ISSUED FOR NATIONAL CITY ACQUISITION
On December 31, 2008, in connection with the closing of the National City acquisition, we issued approximately 1.7 million PNC stock options upon conversion of all outstanding and unexercised National City options at that date. Of the total options issued, approximately 1.4 million were issued as nonqualified stock options, and the remaining 0.3 million were issued as incentive stock options. These PNC options carry generally the same terms and conditions as the original National City options. Per the merger agreement, all outstanding options were deemed fully vested at the acquisition date. Accordingly, no ongoing stock option expense will be recognized for these options. The purchase price consideration for the National City acquisition included approximately $2.0 million related to these options.
