Scott Jagow: Bond insurers are some of the biggest casualties of the subprime crisis. This week we'll find out more about how much damage has been done to companies like MBIA and Ambac. They report their profits, or lack thereof. From New York, Alisa Roth reports.
Alisa Roth: Companies like MBIA and Ambac make their money by guaranteeing bonds. If an issuer defaults, the guarantors pay the investor the principal and the interest.
Used to be, bond insurers made most of their money on municipal bonds. But over the last few years, they started guaranteeing mortgage-backed bonds, too. As mortgages have gone belly up, the insurers have found themselves in trouble.
Gary Ransom is an equity analyst at Fox-Pitt Kelton. He says there's another reason times are tough.
Gary Ransom: The municipal biz still exists, but the amount that is insured has gone down substantially.
Kelton says it's not clear when the muni bond business will pick up. Or what the bond insurance business will look like when the market gets better.
Ransom: The direction we seem to be heading is that we will probably have companies that only insure municipalities and do nothing else.
Municipalities don't default nearly as often as other issuers. So the bond insurance business would be less risky. But also less profitable.
