Regulation FD Disclosure The information below amends Exhibit 99.2 included in the Registrant's Current Report on Form 8-K filed with the SEC on October 17, 2001. Revision to End of Period Net Interest Margin Table In Exhibit 99.2, the third table under the Net Interest Margin bullet point indicated end of period balances for June 30, 2001 and September 30, 2001; however, average balances for the months of June and September were reported. The following table is a correction of that table with end of period balances for June and September: ------------------------------------------------------------------------------------------------------ June 30, 2001 September 30, 2001 Actual Actual ------------------- -------------------------------------------- No Mix Change Current Mix ------------------- --------------------- End of End of End of Period Period Period ($ in 000's) Balance Yield Balance Yield Balance Yield ------------------------------------------------------------------------------------------------------ Loans & leases $3,813,572 8.88% $3,894,680 8.46% $3,894,680 8.46% Investments 1,982,439 6.81% 2,011,931 6.51% 2,468,245 6.52% Cash and cash equivalents 56,385 4.12% 70,256 4.02% 70,256 4.02% ------------------------------------------------------------------------------------------------------ Interest-earning assets $5,852,396 8.13% $5,976,867 7.75% $6,433,181 7.67% ------------------------------------------------------------------------------------------------------ Deposits $3,470,247 3.55% $3,462,643 3.18% $3,462,643 3.18% Borrowings 1,344,926 4.65% 1,314,204 4.29% 1,770,519 4.29% Non-interest bearing deposits and other free funds 1,037,223 1,200,020 1,200,019 ------------------------------------------------------------------------------------------------------ Cost of funds $5,852,396 3.17% $5,976,867 2.79% $6,433,181 2.89% ------------------------------------------------------------------------------------------------------ Net interest margin 4.96% 4.97% 4.77% ------------------------------------------------------------------------------------------------------ Pro forma Net Interest Income - Annualized $ 290,279 $ 297,050 $ 306,863 ------------------------------------------------------------------------------------------------------ The table above indicates the same trend as previously disclosed; the end of period no mix change net interest margin for September 30, 2001 actually increases slightly from the end of the second quarter. This is due to funds cost declining slightly more than yields on interest earning assets. The end of period current mix net interest margin declines by 19 basis points to 4.77%, due to a combination of lower asset yields and higher funds costs. However, once again pro forma net interest income is enhanced by the current balance sheet as pro forma annualized net interest income based on the third quarter net interest margin compared to the second quarter increased by $17 million. Impact on 2002 Performance Guidance The inclusion of this revised table has no impact on the 2002 performance guidance provided in the Current Report on Form 8-K filed on October 17, 2001. 2 SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, as amended, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
