Here's the funny thing about the energy space. Nobody seemed to pay much attention when Aubrey McClendon and Tom Ward were taking on billions of dollars in financing to build Chesapeake Energy (NYSE:CHK) and Sandridge Energy (NYSE:SD) until balance sheets were so bloated they needed to sell assets.

Find out what those key points are by tuning in.
