The bank's shares have been pummeled in recent days following the disclosure of the bank's first quarterly loss in 17 years and mounting concerns about its recent Merrill Lynch acquisition. There's also unrelenting concerns that the government's future plans to help prop up banks could hurt shareholders.
Last week, Lewis went before his directors in Charlotte for "the longest board meeting in anyone's memory," he told employees in the memo issued Monday.
Some analysts said Lewis' job might be on the line, but lead director O. Temple Sloan Jr. later issued a statement of support for the bank's management team.
In the memo, Lewis called the company's performance in January "encouraging." The "extreme dislocations in the capital markets we suffered last quarter seem to have moderated" but "credit costs continue to be a big issue."
He also acknowledged employees are disappointed about cuts to their bonuses. He noted that higher-ranking executives are taking deeper reductions and that neither he nor his top lieutenants are receiving payouts for 2008, according to the memo.
