Capital One Financial Corp. President Lynn Carter is stepping down at the end of the year, according to a filing with the Securities and Exchange Commission Tuesday.

Carter, known as Lynn Pike until she was recently married, runs retail operations for the McLean, Va., bank and was responsible for its integration of Chevy Chase Bank, which Capital One acquired in 2009. She joined Capital One in April 2007 as chief operating officer and was named president in August of that year.

Capital One said in the filing that, with Carter's departure, it is restructuring its senior management team. Michael Slocum, the vice president of commercial banking and president of the New York state market for Capital One Bank, will take over as head of commercial banking, and Jonathan Witter, an executive vice president of retail operations, will be become president of retail banking. Both will be reporting to CEO Richard Fairbank. The company said Carter will stay on in an advisory role through March 31, 2012.
