A computer system or computer-implemented process THAT analyzes pools of loans by considering the combination of interest rates and credit quality which drive asset performance or by incorporating financial reporting. The analysis is called credit-driven because the level of prepayment simulated for each asset in the pool is modulated separately over a projection period based on the projected financial performance of the underlying collateral. Prepayments occur when prepayment is permitted and refinancing results in some specified level of net new proceeds. Similarly, this analysis modulates the level of default simulated for each asset in the pool separately over a projection period. Credit-driven defaults occur when the underlying collateral's net income is insufficient to cover debt service. Following a specified delay, the severity of loss may be computed to reflect the underlying collateral's performance and financeability. Similarly, this analysis modulates the amount of extension simulated for each asset in the pool separately over a projection period. Credit-driven extensions occur when the underlying collateral's income and value are insufficient to support financing of the asset's scheduled balloon payment. Following a specified delay, the balloon repayment is again simulated at which time the asset may experience a balloon shortfall. Such balloon shortfall or calculated severity of loss may be computed to reflect the underlying collateral's performance and financeability. |
