The stock, which fell as low as $20.53 on Friday, recently was trading down 6.7% to $20.83. Second-quarter earnings were affected by a $47 million writedown associated with the company's repayment of the government's $3.1 billion preferred equity investment made through the Troubled Asset Relief Program. The company's bottom line also was hit by $14 million in accrued dividends paid on June 17, when the company exited TARP.

The return on average common shareholders' equity was 3.43%, down from 8.29% the previous quarter and 13.27% in the second quarter of 2008.

The annualized ratio of net charge-offs to average loans was 1.81%, up from 1.58% in March and 0.72% a year earlier.
