OLDWICK, N.J. — A.M. Best Co. has affirmed the debt ratings on a multi-tranche collateralized debt obligation (CDO) co-issued by two bankruptcy remote special purpose vehicles: I-Preferred Term Securities I, Ltd. (Cayman Islands) and I-Preferred Term Securities I, Inc. (Delaware) (collectively known as I-Preferred Term Securities I and issuers). The outlook for all ratings is stable. (See below for a detailed listing of the ratings.)

The principal balance of the rated notes are collateralized by a pool of trust preferred securities, surplus notes and secondary market securities (collectively, the capital securities), primarily issued by small to medium-sized insurance companies. The capital securities are pledged as security to the notes. Interest paid by the issuers of the capital securities are the primary source of funds to pay operating expenses of the issuers and interest on the notes. Repayment of the note principal is primarily funded from the redemption of the capital securities.

These rating actions primarily reflect: (1) the current issuer credit ratings (ICR) of the remaining issuers of the capital securities; (2) a stress of up to 250% on the assumed marginal default rates of insurers (derived from Best’s Idealized Default Rates of Insurers); (3) the amount of capital securities considered to be in distress; (4) recoveries of 0% after defaults of the capital securities; and (5) qualitative factors such as the effect of interest rate spikes; subordination level associated with each rated tranche; the adjacency of very high investment grade ratings to very low non-investment grade ratings in the transaction’s capital structure; and the possibility that additional redemptions of highly-rated entities will leave lower-rated companies in the collateral pool.

The ratings could be upgraded or downgraded and/or the outlook revised if there are material changes in the ICR of the remaining insurance carriers, an increase in the number of defaulted capital securities or significant termination of the number of existing capital securities.

The following debt ratings have been affirmed:
