Moody’s – Credit Rating

The real problem is that the agencies mathematical formulas look backward while life is lived forward. That is unlikely to change.

There are significant limits to what regulation can accomplish. As a dramatic illustration, take two of the biggest accounting disasters in the past ten years: Freddie Mac and Fannie Mae. We’re talking billions and billions of dollars of misstatements at both places.
Now, these are two incredibly important institutions. I mean, they accounted for over 40% of the mortgage flow a few years back. Right now I think they’re up to 70%. They’re quasi-governmental in nature. So the government set up an organization called OFHEO. I’m not sure what all the letters stand for. But if you go to OFHEO’s website, you’ll find that its purpose was to just watch over these two companies. OFHEO had 200 employees. Their job was simply to look at two companies and say, “Are these guys behaving like they’re supposed to?” And of course what happened were two of the greatest accounting misstatements in history while these 200 people had their jobs. It’s incredible. I mean, two for two!

It’s very, very, very hard to regulate people. – Warren Buffett
