Bloomberg News reports: "Chesapeake Energy Corp. Chief Executive Officer Aubrey McClendon will resign from the company he built into the second-largest U.S. natural gas producer after scrutiny of his personal finances and a corporate cash crunch erased as much as 43 percent of its market value last year.

"McClendon will retire from the company April 1 and will serve as CEO until his successor is appointed, Oklahoma City- based Chesapeake said today in a statement. "The board said to date it has found no evidence of improper conduct in the CEO’s relationship with the company. It will release its review on Feb. 21, when announcing earnings results."
