Chesapeake Energy said it has received a request from the US Securities and Exchange Commission over its accounting methodology for the acquisition and classification of oil and natural gas properties.
The company said it had also been handed a subpoena from the Department of Justice related to the same issue.
A class action lawsuit was filed in a US District Court last month against Chesapeake which alleged violations of securities laws for “purported misstatements” in its public filings, the firm said in a regulatory filing on Thursday.
Chesapeake said earlier this year it received subpoenas and demands for documents from the Department of Justice and some state government agencies in connection with investigations into possible violations of antitrust laws.
The firm had come under scrutiny when former Chief Executive Aubrey McClendon, who helped transform the U.S. energy industry with shale gas, was charged in March with conspiring to rig bids to buy oil and natural gas leases in Oklahoma.
