Chesapeake Energy Corp. (CHK) reported a third-quarter net loss available to stockholders of $4.695 billion, or $7.08 per share, compared to net income available to stockholders of $169 million, or $0.26 per share, prior year. The company said the primary source of this reduction was a noncash impairment of the carrying value of Chesapeake’s oil and natural gas properties largely resulting from significant decreases in the trailing 12-month average first-day-of-the-month oil and natural gas prices as of September 30, 2015, compared to June 30, 2015.
