AD&CO. provides version-specific online demos designed for the user to enter the characteristics of a given pool/loan. The model forecasts prepayments throughout the remaining life of that pool/loan and then outputs those results. Many clients use these demos to ensure that particular models are properly integrated within third-party systems.

To help evaluate the robustness of our models, we provide Mortgage Analysis & Reporting to compare our model predictions against actual market experience. These reports allow the user to specify different analysis periods, origination periods, and net coupon levels.
AD&Co's Mortgage Analysis & Reporting tap into our extensive database of historical prepayment speeds to track the actual vs. forecasted performance of MBS Agency Fixed, ARM and hybrid loan types in our model. These are not canned reports, but actual real-time dynamically generated outputs from our model driven by user-defined requests to a secure AD&Co. server.

Market Valuation Reports provide OAS, duration, convexity and key rate durations for the actively traded 30year agency TBAs. These numbers are generated on a weekly basis and use AD&Co's prepayment, term structure (Hull White) and valuation models (using market prices) to give an objective market standard view of the relative value of these key securities. All assumptions are clearly displayed at the top of each report so that users can assess the reasonableness of the outputs from any vendor or internal system that uses the AD&Co. Prepayment Model.
This evaluation is an important step in the validation of the proper integration of the AD&Co prepayment or valuation system into a third party system.
Another feature of the Market Analysis Report is the Risk Neutral based outputs. These results are generated using risk-neutral tunings that are calibrated to minimize the OAS variability on the respective agency backed debentures. The actual tuning adjustments made to the refi, turnover, burnout and slide parameters are shown at the top of the report in the Risk Neutral Tunings box. Link to Market Valuation Reports |
