The web-based service will track the performance of more than 3,700 European residential mortgage-backed securities (RMBS) rated by S&P. It tests the performance of each transaction periodically as the investor and servicer reports come in for each deal, and warns if a specific asset is close to being reviewed for downgrade.
The service monitors several factors. Improvements in pool factor and credit enhancement ratio can trigger a positive review, while negative reviews can be triggered by deterioration in delinquency ratio, delinquency growth, cumulative loss growth, cumulative loss ratio or by reserve fund reduction.
S&P says the service will also include consumer asset-backed securities and commercial mortgage-backed securities in the future.
