IDC Interactive Data Corp.

Interactive Data Corporation (NYSE: IDC), a leading provider of financial market data, analytics and related services, today announced an exclusive agreement between its Pricing and Reference Data business and Prism Valuation. Under the agreement, Interactive Data Pricing and Reference Data will now have the capability to provide valuations of highly complex OTC derivatives and structured products as part of its wide-ranging pricing and evaluation services. Prism Valuation, which was founded in 2006 and maintains offices in London, Melbourne and Toronto, provides valuations of complex OTC derivatives and structured products based on a wide range of underlyings including: interest rates, FX, inflation, equities, credit, commodities and hybrids. Interactive Data�s clients will be able to request valuations on a per instrument basis, which will be calculated by Prism Valuation�s quantitative analysis team and then delivered via FTSSM, Interactive Data�s securities administration tool. Interactive Data already has clients who are subscribing to these valuations. The Prism Valuation team emulates the valuation processes of a typical structured products dealer by synthesizing the most important components required for valuation and analysis: up-to-date market data, appropriate valuation models and targeted calibration strategies. The service that Interactive Data will offer includes valuation transparency reports that provide a breakdown of the method to achieve a given valuation for each deal, including a detailed discussion of the models and calibration strategies selected. This level of transparency can help clients comply with current regulatory and auditing demands. Prism Valuation has a core team with many years of direct front office and quantitative experience at structured products dealers. In addition, Prism Valuation�s strategic partnerships include ICAP, the world�s premier interdealer broker, which provides underlying market data, and NumeriX, one of the foremost global providers of cross asset pricing and risk analytics for exotic derivatives and structured products. Prism Valuation�s market experience and important strategic relationships enable valuations of derivatives and structured products across multiple asset classes. As part of this strategic alliance, Interactive Data has purchased a minority ownership stake in Prism. Financial terms of the investment were not disclosed. Greg Cripps, president and CEO, Prism Valuation, said, �We are delighted to enter this relationship with Interactive Data, which has many years of experience in evaluated pricing, and extensive global distribution channels.

About Prism Valuation Prism Valuation was founded in June 2006 to offer independent valuation services of complex structured products in all asset classes. Prism Valuation has a core group of people with direct front office experience from structured product dealers, most of whom also hold PhDs in Science or Engineering.

Prism Valuation is not affiliated with any structured dealer and is therefore able to offer an independent valuation analysis. Prism Valuation is also able to evaluate and perform analysis on deals not yet in the broader market domain for clients involved in newer structured products. Prism Valuation has strategic relationships with ICAP, the world�s premier interdealer broker, for reliable, up-to-date underlying data, and NumeriX, one of the foremost global providers of cross asset pricing and risk analytics for exotic derivatives and structured products.
