Bank of America Corp. chief executive Brian Moynihan insisted Wednesday that his company won't have to raise additional capital as it absorbs mortgage-related losses.

Banks need to keep sufficient capital on hand as a cushion against unexpected losses. In the wake of the financial crisis, new global standards will require them to hold even more over time.

Moynihan, who has been CEO for 18 months, has repeatedly said the Charlotte bank is improving its capital ratios by accumulating earnings and shedding riskier assets, but he faced another round of questions about the issue Wednesday at an investor conference in New York.

"We don't see any reason to raise capital at all," Moynihan responded.

Bank of America faces billions of dollar in requests from investors to buy back soured mortgage loans originated by Bank of America and Countrywide Financial, which it bought in 2008. It has reached settlements with some investors and continues to have talks with others.

Moynihan said the bank wants to put the issue behind it, while also paying settlement amounts that are "reasonable" to its shareholders.

On another issue of keen interest to investors, the CEO wasn't specific about when Bank of America will ask the Federal Reserve for permission to increase its penny-per-share quarterly dividend. The Fed in March rejected the bank's request to modestly hike the payout in the second half of this year, even as other big banks received permission for increases.

"Stay tuned," Moynihan said. "We've learned our lessons about the process."

Echoing comments he made at the bank's annual shareholder meeting last month, Moynihan said Bank of America needs to finish integrating Merrill Lynch risk management systems and continue reducing "unknown risk" at the company, likely referring to the mortgage repurchase requests.

Asked about settlement talks with state attorneys general over foreclosure-related errors at major loan servicers, Moynihan said the dialogue is ongoing, but it will take longer than people think to reach an agreement because of the amount of work involved.

Bank of America shares are down more than 15 percent this year, closing at $11.24 on Wednesday after falling more than 4 percent on a down day for Wall Street.
