Bank of America Corp. Chief Executive Kenneth D. Lewis announced his resignation, effective by the end of the current year, on Wednesday (September 30). The 62 year-old, who has been on the position since 2001, is reportedly fed up with the criticism related to the takeover of Merrill Lynch & Co.

“Bank of America is well positioned to meet the continuing challenges of the economy and markets,” Mr. Lewis said in a statement released by the company. “The Merrill Lynch and Countrywide integrations are on track and returning value already. We are in position to begin to repay the federal government’s TARP investments.”

BOA still doesn’t have a successor but assured they would select a successor by the time Lewis steps down December 31, 2009, which indicates the company’s board did not expect Lewis’ decision at this time.
