I want to know the answer to the following question:
Who was Southern California-based IndyMac a spin-off of?
All the background I'm provided with is that "The failure of IndyMac Bank on July 11, 2008, was the fourth largest bank failure in United States history up until the crisis precipitated even larger failures, and the second largest failure of a regulated thrift.". Is that enough to answer the question?
Answer: no
