NEW YORK--(BUSINESS WIRE)--
Fitch Ratings has affirmed eight classes in four Structured Asset Securities Corporation (SASCO) Reverse Mortgage Transactions. A spreadsheet detailing Fitch's rating actions can be found at 'www.fitchratings.com' by performing a title search for 'SASCO Reverse Mortgage RMBS Rating Actions for June 4, 2014'.
KEY RATING DRIVERS
The reverse mortgage transactions reviewed are collateralized by mortgage pools consisting of one-to-four family, first lien, non-recourse reverse mortgage loans. A portion of the mortgage loans provide for periodic credit line draws by the borrower. Each transaction has a funding account comprised of cash and/or securities to fund these draws. No interest or principal is due on the loans until the occurrence of a maturity event triggered by the borrower moving, passing away, selling the home, or voluntarily prepaying the loan in full.
As maturity events occur and the reverse mortgage loans are repaid, funds are allocated to pay interest and principal on the notes. Since maturity events may not occur in a consistent pattern over time, the funding accounts are also required to maintain several months of interest reserves to cover potential interest shortfalls on the notes. Currently, all of the transactions' funding accounts are at, or near, their target amounts.
The loss amount on each loan was calculated by first estimating the current market value of the property and then applying Fitch's market value decline assumptions which range from 10% in 'Bsf' stress to 35% in the 'AAAsf' stress. Fitch then calculated the carry cost on the loan (accrued interest, taxes, insurance, legal fees) that would occur during the liquidation timeline.
Fitch assumed liquidation timelines for each rating stress which ranged from 15 months in the 'Bsf' stress to 30 months in the 'AAAsf' stress, six months shorter than the timelines Fitch assumes for non-Agency distressed loan liquidations. The loss on each loan was derived by subtracting the current loan balance of the reverse mortgage plus the carry cost from the adjusted home value. Loss analysis was conducted only on loans that have matured or are expected to mature within the next 10 years based on the borrower's profile.
Finally, the loan level loss in each rating category was tallied to determine the overall loss at each rating stress. On average the losses ranged from 29% in the 'Bsf' stress to 52% in the 'AAAsf' stress.
