Fixed-Income Toolbox

Product Description

Mortgage Pool and Balloon Mortgage Pricing

Fixed-Income Toolbox lets you model generic fixed-rate mortgage pools and balloon mortgages. The toolbox provides tools to calculate price and yield of mortgage-backed securities using prepayment options derived from uniform practices of the Public Securities Association (PSA). You can calculate the mortgage-pool price or effective duration using the option adjusted spread method for your mortgage pool. You can also measure the risk for a mortgage-pool portfolio using convexity, duration, and average life calculations.
