Thankfully (especially since we're still mopping up after last week's 10-K filing deadline) we didn't have to wrack our brains too much. There in the 10-K that Chesapeake Energy (CHK) filed just 12 minutes before the deadline on Feb. 29 was this exhibit. First, the positive: unlike some other companies last week, like Metlife (MET), whose 10-K included 21 separate exhibits designed for the typical investor's reading pleasure, Chesapeake's 10-K only had one exhibit.
