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 V A 0.50 AAA(so) (Reaffirmed)

CRISIL has reaffirmed its rating on the Series A pass through certificates (PTCs) issued by Indian RMBS Trust Series V. This reaffirmation follows the fresh assignment of mortgage loans to the pool as per the terms of the transaction. The PTCs are backed by a pool of residential mortgage loans originated by ICICI Bank Ltd (ICICI Bank). The rating reaffirmation is 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 securitisation transaction. The reaffirmation factors in the assignment of fresh loans to the pool.

From the original pool, with a principal of Rs.1 billion, two strips were carved out ? Series A and Series P. Under the transaction structure, Series P was to receive all the principal repayments/prepayments during the first five years of the transaction. Once Series P was fully repaid, the principal repayments in the pool were to be passed on to Series A PTCs. If the sum of principal balances of Series A and Series P PTCs fell below Rs.0.6 billion within 54 months of securitisation, the trustee, IDBI Trusteeship Services Limited (ITSL), had an option to call upon ICICI Bank to assign a fresh set of loans to top up the pool, so that the sum of principal balances of Series A and Series P PTCs was restored to Rs.1 billion. The sum of principal balances of Series A and Series P PTCs has now fallen below Rs.0.6 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 with principal balance of Rs. 0.45 billion on the pool cut-off date.

The freshly-assigned loans have a high average seasoning of 64 months, and moderate original loan-to-value (LTV) ratios (weighted average – 70.6 per cent). CRISIL believes that the effective LTV ratios of these loans have improved significantly, given the amortization of the loans and 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 pool performance
The pool was securitised in February 2005; over the past 46 months, 43 per cent of the pool has been amortised. The credit collateral of Rs.18.5 million is intact. The 90+ days past due (dpd) and 180+ dpd are moderate at 2.49 per cent and 1.79 per cent, respectively, of the original pool principal. The cumulative collection efficiency is also high at 98.7 per cent.

About the Originator
Promoted by the erstwhile ICICI Ltd, ICICI Bank was incorporated in 1994. In March 2002, ICICI Ltd was merged with ICICI Bank. ICICI Bank is India’s second-largest bank, with an asset base of Rs.3.99 trillion as on March 31, 2008. The bank reported a profit after tax (PAT) of Rs.41.6 billion in 2007-08 (refers to financial year, April 1 to March 31), as against a PAT of Rs.31.1 billion in 2006-07.
