_____________________ (1) Includes FG VIEs. (2) A risk represents the aggregate of the financial guaranty policies that share the same revenue source for purposes of making debt service payments. The following table shows the scheduled amortization of the obligations of the Puerto Rico authorities and public corporations that the Company insures. The Company guarantees payment of interest and principal when those amounts are scheduled to be paid and cannot be required to pay on an accelerated basis, although in certain circumstances it may elect to do so. In the event that obligors default on their obligations, the Company would only be required to pay the shortfall between the debt service due in any given period and the amount paid by the obligors.

See Note 8, Financial Guaranty Variable Interest Entities and Consolidated Investment Vehicles. (2) All debt service on these insured exposures have been paid to date without any insurance claim being made on the Company.
