MDA Announces Launch Of Automated Property Valuation In Germany

Richmond, B.C. - MacDonald, Dettwiler and Associates Ltd. (TSX: MDA), a provider of essential information solutions, announced today that Wertweiser GmbH, its joint business initiative with HVBExpertise GmbH in Germany, has signed its first contract and is launching its automated valuation service.

This first booking by Wertweiser is a multi-year contract with HypoVereinsbank (HVB), member of the UniCredit-Group, to provide valuations to support its point-of-sale mortgage origination and underwriting of residential properties across Germany. This contract is expected to ramp up over the next few months at which time it will be fully integrated with HVB's workflow. Over the term of the contract, the range of valuation services provided is anticipated to expand to meet the need of HVB to comply with the new Basel II international banking standards.

Wertweiser's information solution is designed to reduce the overall time and cost involved in professional real estate valuation, by automating labor-intensive parts of this process using analytical algorithms and models which draw on extensive property data sources accumulated over time. This service will be marketed to financial institutions, such as banks, building and loan associations, and insurance companies that are active in the German real estate market.

"The Wertweiser valuation service will be the first of its kind in the German market, and it is expected that other German mortgage banks will be very interested in taking advantage of the operational efficiencies and customer service improvements that are made possible with the use of Wertweiser services" said Raymond Trotz, Chief Appraisar of HypoVereinsbank. "This multi-year commitment by the parent of our founding business partner HVBExpertise will put Wertweiser on a sound financial footing and enable the company to explore expansion opportunities in the German and other European markets", said John Geddes, Vice President of Business Development at MDA and a member of the Wertweiser Management Board.
