Bermuda-based Assured Guaranty Ltd. yesterday put its public finance exposure to areas affected by Hurricane Katrina at $155 million.

The company's exposure in FEMA-designated counties was greatest in New Orleans at $77.6 million, with another $61 million of exposure in other parts of Louisiana. The company expects about $8 million in Alabama and Mississippi.

The company's exposure to investor-owned utilities in the affected states totals $65.9 million.

The majority of the company's exposure is in its financial guaranty reinsurance segment, the statement said, however Hurricane Katrina's impact on the credit quality of these exposures cannot be determined at this point in time.

The company said that a review of its structured finance portfolio shows no significant concentrations in the areas affected by Hurricane Katrina as these transactions are generally backed by geographically diverse pools of assets.
