MBIA Loses AAA Insurer Rating From Fitch Over

Bloomberg reports:

Fitch Ratings cut MBIA Inc.'s insurance unit to AA from AAA, saying the bond insurer no longer has enough capital to warrant the top ranking.

MBIA, the world's largest financial guarantor, would need as much as $3.8 billion more in capital to deserve an AAA, New York-based Fitch said today in a report. The outlook is negative, Fitch said.
