PG&E's imminent bankruptcy would put it in rarefied air alongside Enron and Lehman Brothers

• PG&E's impending bankruptcy would put it in notorious company, at least in terms of size.
• The company would join the ranks of "failing angels," or companies whose debt goes straight from investment grade to default.

If PG&E follows through on plans to file for bankruptcy before the end of the month, it will be the biggest utility bankruptcy since 2001...which was the first time PG&E filed for bankruptcy.

By the numbers: PG&E's planned filing would be the ninth largest bankruptcy since at least the mid-1980s — falling just below the likes of Lehman Brothers, WorldCom and General Motors.
