Analytics Enhancements
A primary objective of the new RiskModel is seamless integration with client in-house systems—expanding front-line automated processing to include state-of-the-art predictive analytics. Since this required reengineering RiskModel from top-to-bottom, we took the opportunity to extend and streamline its core functionalities:

Some examples of RiskModel’s analytics enhancements:

• New subprime statistical model features a fully redeveloped LGD model utilizing significantly more data (two years additional historical data, 370,000 additional observed losses). Enhanced equations improve capture of the effects of changes in housing prices and interactions between loan characteristics. A new LGD validation study provides results of back-testing Alt-A and nonprime loans liquidated between January 2007 and March 2008.
• New adjustment dials for prime, subprime, Alt-A. and HELOC collateral, including the ability to dial-on simulation month and change in home price index (HPI).
• Added Core-Based Statistical Area (CBSA) codes increase HPI granularity by enabling user-defined HPI path files to specify any of 432 standard CBSA codes.
• New data management utility offers seamless data file import/export via translation of proprietary housing price, interest rate, and exposure assumption files into comma-separated (CSV) files. Exported data can then be viewed, modified, and imported back into RiskModel for additional processing.
• New loss severity equations feature recalculated severities for various liquidations, ARM loans, investor properties, multi-family dwellings, loan type segments.
• New HPI simulation model offers historically accurate boom and bust cycles, accurate long-term HPI volatility for better default/loss distributions, longer economic capital horizons, historically linked returns in location, linked returns in other locations, Core Business Statistical Area (CBSA) definitions.

In addition to reengineered functionality, RiskModel simulations now reflect recent turmoil in the mortgage market accurately. For example, estimated subprime prepayment speeds factor in observed prepayment increases during 2003-2005, subprime loan characteristics include more precise and telling detail, transition equations mirror recent factual data, payment history variables offer greater insight and control.

New Subprime, HELOC, LGD, HPI Models
RiskModel’s rich library of prime, alt-A, and nonprime statistical models has grown to include new subprime, HELOC, Loss Given Default (LGD), and Housing Price Index (HPI) models that are specifically designed to cope with the current mortgage industry crisis. Sample changes:

• Enhanced Home Equity Line of Credit (HELOC) model features new calibration dials, loan-level reporting metrics for loss forecasting, and portfolio-level cash flow reporting.
• New subprime model includes ARM rate reset-specific parameters, redefined prepayment and default estimates, more recent data affecting default.
• New LGD model includes second lien statistical loss severity, redefined severity equations for first lien liquidations, additional 150,000 recent loss records.
• Enhanced Prime option ARM transition model affects prime option ARMs with 18-month or less resets, improving credit risk projections for this class of loans.
• New HPI simulation model includes general time dependence in returns, return as function of previous returns, contemporary dependence in returns across locations.

Extensive back-testing documenting the substantial performance improvements achieved using the new subprime, LGD, and HPI simulation models is available for review. Please contact the LoanPerformance representative for your geographic area.

Automated Data Conversion Wizard
The new RiskModel data conversion wizard allows you to run any OLEDB (Object Linking and Embedding Database) or ODBC (Open Database Connectivity)-compatible database file through RiskModel simulations, then reverse the process and output data in any desired reporting format. Other new features include:

• Data viewer added that allows review of source data prior to conversion.
• Data analyzer matches specified source data with an existing template.
• Column mapping enables advanced formatting to the source data.
• Data translation allows non-resident source data to be converted.
• QA checks/messages define errant data and actions to correct.

Conversion processing also allows conditional mapping as part of the user-defined QA checks (for example, “delay mapping until the QA checks are executed and use conditional parameters to map source data to RiskModel input field”).

Reengineered GUI (RiskModel Desktop)
The RiskModel Desktop graphical user interface (GUI) has been completely reengineered to extend and simplify user control over its full range of sophisticated predictive analytics. Some of the more significant changes:

• Setup supports multiple open projects, simplified setup process, easy error correction, new copy-and-paste capability, new data explorer function.
• Simulation controls simplified and clarified, multiple jobs possible in one project, online report access, maximum error specification capability.
• Reports can be grouped by portfolio or loan level, over-time reports permit sub-reporting, customizeable output processing for all reporting types.
• Data inputs and handling functions expanded and clarified, conversion from/to any OLEDB-compliant format, supports single and multiple input conversions.
• HPI expanded, simplified controls of housing price inputs, geographical areas defined by CBSA codes, regional volatility parameters, vector selection added.
• Segmentation now separate utility giving more control and allowing multiple conditions for segment, ability to generate specified-segment outputs.

This sampling of updated GUI-controlled RiskModel Desktop capabilities does not capture the full effect of its much-enhanced usability. The new GUI is not a surface upgrade—it represents extensive user testing and a commitment to reengineer everything necessary.

API Engine (RiskModel Enterprise)
RiskModel Enterprise is an API engine that can be embedded in mortgage processing and trading systems to analyze huge volumes of securities and bonds, evaluate them in light of the latest housing price, interest rate, default and loss severity rate fluctuations, then produce realistic, accurate results in time to capitalize on immediate trading opportunities.

RiskModel Enterprise users enjoy significant benefits:

• Faster decisions RiskModel Enterprise API enables the inclusion of sophisticated risk analytics in evaluating thousands of securities at automation-level speeds, giving traders invaluable, real-time perspective on the likely accuracy of current bond pricing.
• Better-quality decisions RiskModel Enterprise API improves the quality of the risk analytics process, transforming a multiple-step, manpower-intensive, easily-skewed procedure into a tightly integrated, consistently reliable, easily managed predictive process.
• Consistent application of proprietary view RiskModel Enterprise API can be set to apply unique client perspective on housing prices, interest rates, consumer confidence, other parameters for projecting roll-rates, prepayments, defaults and loss severity.

The RiskModel Enterprise API engine inputs predictive data to enterprise system components like mortgage securities waterfall and option-adjusted spread-pricing applications. RiskModel's performance projections—incorporating client perspective on key industry trends—become unequivocal valuation parameters, significantly improving the trustworthiness of subsequent bond analytics and pricing decisions.
