The software offers flexibility in analyzing pricing and risk, allowing users to modify prepayment models, export cash flow components, and conduct ROW analysis based on funding and MSR exit strategies. WinOAS™ generates asset valuation reports in multiple formats (PDF, XLS, HTML) and models future asset behavior based on collateral characteristics and market assumptions. It provides comprehensive SOX controls, detailed documentation, and access to daily Generic Servicing Assets (GSAs™) pricing.
