## What is Semi Annual Bond Yield?

Semi Annual Bond Yield is the fraction of the remaining mortgage loan principal that is prepaid in a single month. Prepayments can occur when homeowners pay off their mortgage ahead of schedule, often due to refinancing, selling the home, or making extra payments. Conditional Prepayment Rate is an annualized measure of the prepayment rate for a loan pool. For investors in mortgage-backed securities, a higher SMM indicates a higher rate of prepayment, which can affect the expected cash flows and yields from these securities. Lenders and servicers monitor SMM to understand prepayment behaviors and manage the servicing of loans. Single Month Mortality is a crucial measure in the mortgage finance industry, indicating the percentage of the remaining principal that is prepaid in a single month. Derived from the Conditional Prepayment Rate, it helps investors and lenders assess prepayment risk and manage their portfolios effectively. Understanding SMM is essential for accurately forecasting cash flows.
