Chesapeake Energy confirms U.S. SEC probe
Reuters first reported last week that regulators in the agency's Fort Worth office were looking into a controversial program that grants McClendon a share in each of the wells Chesapeake drills.
The company and McClendon have been asked to retain certain documents, Chesapeake said in a statement, but it did not provide additional details.
Chesapeake and McClendon are cooperating with the SEC, the company said.
