U.S. Bankruptcy Judge David Jones of Houston has approved the billion-dollar bankruptcy reorganization of mattress giant Serta Simmons, which also meant a monumental victory for a handful of investors in distressed debt and a huge legal defeat for some Wall Street leaders. The debt restructuring plan approved by Judge Jones cuts Georgia-based Serta Simmons’ secured debt from $1.9 billion to $315 million. In doing so, the judge coined a new term – position enhancement transaction or PET – that you need to learn.

The five-day trial was led for the Serta Simmons lenders by new Gibson Dunn partner Gregg Costa. This was Costa’s first trial since retiring from the U.S. Court of Appeals for the Fifth Circuit and his first-ever trial in bankruptcy court.
