Buffett said he he made the offer to Ambac (NYSE: ABK), MBIA (NYSE: MBI) and FGIC.
The move will certainly put some wind in the sails of bulls who have taken a beat on Ambac and MBIA, but before you get too excited, consider that the Associated Press is reporting that the offer would only back municipal bonds and not other risky and complicated financial instruments.
Municipal bonds make up about two-thirds of the insurance industry's portfolio, with asset-backed securities making up the other third. But the asset-backed securities are probably the bigger concern.
It will be interesting to see if William Ackman, who has been vocally bearish on the industry for a long time, will have any comments on Buffett's offer.
