S&P Rates MMCA Auto Owner Trust Asset-Backed 1998-1 NotesNEW YORK, Aug. 20 -- Standard & Poor's today assigned its ratings to MMCA Auto Owner Trust 1998-1's various classes of asset backed notes (see list below). Credit support will be provided by 6.50% class B subordination, 10.5% certificates class subordination and a nondeclining reserve account that builds from 0.15% to 0.75% of the original note and certificate balance from excess interest collections. Additional credit enhancement is provided by a yield supplement account that provides coverage for any yield deficiency due to the inclusion of incentive rate loans. This account is sized at closing to bring the aggregate weighted average coupon on the underlying collateral up to a yield of approximately 8.78% (the sum of the weighted average bond coupon plus the servicing fee plus 2.00% of excess spread). A supplemental reserve account, which is funded monthly with excess spread and builds from 0% at closing to 2.00% of the original note and certificate balance, will be used to cover the current month's principal and interest shortfalls. MMCA Auto Owner Trust 1998-1 marks Mitsubishi Motors Credit of America Inc.'s (MMCA) fourth entry into the public asset-backed market. This transaction is unique in that there is $305.8 million of balloon payments securing the notes and the transaction structure monetizes 68% of the balloon payments. In the two previous securitizations, MMCA Auto Owner Trust 1995-1 and MMCA Auto Owner Trust 1997-1, only the level pay portion of the balloon receivables was securitized and the balloon payments were utilized as credit enhancement only. This transaction securitizes a portion of MMCA's retail auto, Fuso medium-duty truck and retail auto balloon receivable portfolio. The collateral at closing consists of 53,764 contracts having an aggregate unpaid principal balance consists of about $930.2 million. The initial pool balance consists of 44.21% retail auto loans; 1.29% to medium-duty truck loans and 54.5% balloon loans, which amortize the amount financed over a series of fixed level monthly installments, but which also require a substantially larger final payment of principal together with one month's interest (the balloon payment) after payment of the monthly installments. In 1995 and 1996, MMCA experienced increases in delinquency and credit losses. Adverse performance was attributable to the use of generic scorecards which had lost their predictiveness and the disruption in collection activities caused by centralization of all servicing functions in May 1995. MMCA addressed these issues by implementing new scorecards in November 1996, improving the performance of its collection staff with ongoing training and developing a behavioral collections model in-house. These changes have translated into improved performance on the serviced portfolio. Total delinquencies (over 30 days) decreased to 4.93% as of June 30, 1998 from 5.87% in the prior-year comparable period. Net losses as a percentage of average principal outstanding for the six months ended June 30, 1998 were 2.59% annualized versus 3.72% for the comparable period in 1997 and 3.38% for the year-ended 1997. Based on portfolio performance, prior rated static pool performance and a static pool analysis of originations, Standard & Poor's expects cumulative net credit losses for this pool to be 3.15% of the level payment portion of the original pool balance. To determine the additional enhancement needed to cover balloon payment loss, Standard & Poor's applied existing methodology employed in auto leasing transactions to determine the residual value exposure to the trust. Balloon payment realization depends on the amount booked at the inception of the loan and the number of vehicles that are returned at loan termination. MMCA has had a historical return rate of 26.05% for balloon loans originated since 1993 when the company began originating this product. To stress the return rate, Standard & Poor's assumed a 100% return rate under the triple-'A' scenario and an 80% return rate under the single-'A' scenario. The severity of residual loss for these balloon payments and, therefore, how much would be realized on termination was estimated by comparing the booked residual values with the residual values for the collateral projected by the Automotive Lease Guide (ALG), which are based on historical data. The average residual value for the collateral related to the balloon loans in this pool is 60.2%. The average ALG estimate is 54.0%. Under a worst case scenario, the future residual value may fall below the ALG estimate as a large number of cars have been coming off lease in recent years. Standard & Poor's has determined that a 20 percent haircut to the ALG estimates would yield a severity assumption consistent with an triple-'A' stress scenario. The residual exposure in this transaction was determined by multiplying the frequency of residual loss (return rate) by the severity of residual loss. -- CreditWire RATINGS ASSIGNED $200 million 5.621% money market class A-1 notes A-1+ $250 million 5.72% class A-2 notes AAA $322.05 million 5.86% class A-3 notes AAA $60.46 million 6.07% class B notes A
