Pathways Issue No. 9

The June 2020 issue of Pathways is now available! In this month’s case study, David Oh demonstrates how you can configure your PolyPaths environment to run multiple versions of a prepayment and loss model. As third-party models have offered COVID-related tuning adjustments, this feature has been leveraged to compare results across baseline vs. tuned versions of behavior models, in order to see the overall impact on the forecasted cash flows, valuations, and risk.

Making Predictions using Time Series Analysis via PolyPaths

PolyPaths v7.10 revamps the ability to perform time series analysis interactively in AppPort using data stored in the Enterprise database. Using this tool clients can easily visualize recent trends in both market data and their internal valuations. For example, market data such as the 30-year mortgage rate and the 10-year CMT rate can be plotted together to track their relationship through time. Clients can watch our webinar here to learn more.

MSR Valuation and Hedging Webinar Recording Now Available

Whether running loan-level and/or cohort-level analysis, we support static and option-adjusted valuations of mortgage servicing rights and their associated hedges. Our flexible cash flow model includes the standard set of income and fees, along with various customization options. In this webinar we also overview recent enhancements we have made to support forbearance-related adjustments. View the recording here.

Rate Floors

With the low rate environment and permittance of negative rates in some interest rate models, we’ve received inquiries on both allowing and constraining negative rates in security valuation. For CMO floaters with embedded caps and floors, users can toggle our Ignore Index Cap/Floor field to allow index rates to go beyond any preset cap or floor. For Mortgage Servicing Rights, clients can optionally impose a floor on all floating servicing cash flow strips including T&I and P&I Float. In Scenario Analysis, our Floor Negative Rates option supports both non-negative and negative floors. Please reach out to us at for any help in restricting or relaxing negative rates as part of your analysis.
