After nearly four years heading the Securities and Exchange Commission, Chairman Mary Schapiro announced on Monday that she will depart the post, effective Dec. 14, 2012.
The White House announced on Monday that President Obama was naming Elisse B. Walter, a commissioner at the SEC, as the new chairman. Walter will not step into an interim post, but will take over the top spot for the foreseeable future. Since she has already been confirmed as a commissioner by the Senate, she will not need to be reconfirmed as chairman, easing the transition.
