CRISIL reaffirms highest rating on PTCs issued under ICICI Bank’s mortgage-backed securitisation transaction
Trust Name PTC Series Issue Size (Rs. Billion) Rating
Indian RMBS Trust Series IV A 2.00 AAA(so) (Reaffirmed)

CRISIL has reaffirmed its ratings on the Series A pass through certificates (PTCs) issued by Indian RMBS Trust Series IV and backed by residential mortgage loans originated by ICICI Bank Ltd (ICICI Bank). The ratings have been reaffirmed based on the performance of the pool, the strength of the credit quality of the pool’s future cash flows, ICICI Bank’s origination and servicing capabilities, the credit collateral, and the structural features of the transaction. The reaffirmation factors in the assignment of fresh loans to the pool, explained below.

Out of the original pool principal of Rs.4 billion, an unrated Rs.2 billion strip (Series P) was carved out to receive all the principal repayments/prepayments during the first five years. Once Series P is fully repaid, the principal repayments in the pool will be passed on to the Series A PTCs. According to the terms of the transaction, if the sum of principal balances of Series A PTCs and Series P PTCs falls below Rs.2.4 billion within 4.5 years of Declaration of Trust, the trustee has a one-time option to call upon ICICI Bank to assign a fresh set of loans (satisfying pre-identified selection criteria) to top up the pool so that the sum of principal balances of Series A and Series P becomes Rs.4 billion. The sum of principal balances of Series A PTCs and Series P PTCs has fallen below Rs.2.4 billion, and Series P is nearing full redemption; the trustee has, therefore, exercised the top-up option, leading to the fresh assignment of mortgage loans.

The freshly-assigned loans have a high average seasoning of 50 months, and moderate original loan-to-value ratios (LTVs). CRISIL believes that the effective LTVs of these loans would have improved significantly, given the sharp increase in home prices over the levels prevailing when these loans were originated.

CRISIL has outstanding ratings on 16 housing loan pools originated by ICICI Bank. The performance of these pools has been good, with strong collections and low delinquencies.

About the performance of the pool
The pool was securitised in October 2004; over 48 months, it has been amortised by 50 per cent. The credit collateral of Rs.74.0 million stipulated in the rating is intact. The 90+ days past due (dpd) and 180+ dpd delinquencies are low at 0.81 per cent and 0.64 per cent, respectively, of the original pool principal. The cumulative collection efficiency is also high at 98.7 per cent.
