MDA Signs More Contracts For Its Electronic Valuation Business In U.K.

Richmond, B.C. - MacDonald, Dettwiler and Associates Ltd. (TSX: MDA), a provider of essential information solutions, announced today that its U.K. subsidiary Xit2 has signed agreements for its valuation solution with three U.K. mortgage firms, Orchid Financial, Shoparound Mortgages and Coast to Coast Properties.

MDA's valuation solution is a proprietary internet-based business-to-business solution, which connects the country's lenders with surveyor panel managers and their panel of chartered surveyors (the equivalent of appraisers in North America). Through this solution, MDA manages the interface between lenders and surveyors, which include surveyor selection, secure electronic document exchange, valuation report generation, payment disbursements, and Quality Assurance services to ensure full compliance with the lender's requirements.

Gary Hall, Managing Director at Shoparound Mortgages, said, "When you look around the valuation market, there is little doubt that MDA's valuation solution uses the most advanced technology and is the most reliable. Further, it keeps everyone up-to-date and informed, which delivers a tangible benefit to our intermediaries, clients and surveyors."

David Rae of Coast to Coast said, "Our primary concern is to complete the sale of properties as quickly as possible for our clients, and MDA's valuation solution will be an enormous help in achieving that goal."
