MDA enters partnership with advanced property valuation company in US

Richmond, B.C. - MacDonald, Dettwiler and Associates Ltd. (TSX: MDA), a provider of essential information solutions, announced today that it has entered a strategic partnership with U.S. based ValueScape LLC, an emerging leader of alternative property valuation solutions. Over the next two years, MDA will make an equity investment of several million dollars to finance the growth of the company. MDA will also have an option to acquire 100% of the equity in the future.

ValueScape offers a range of property valuation services, including its proprietary Interactive Valuation Model (IVM). These valuation services will complement MDA's existing property information and automated valuation products. IVM is unique in that it now provides appraisers with direct access to MDA's rich property data archive, and with powerful statistically validated analytical tools, will more rapidly and accurately complete appraisals required for mortgages and equity loans.

John Geddes, MDA vice president of strategic business development states, "We believe that with the current emphasis on the integrity of collateral valuation in the U.S., lenders will quickly see the benefits of this new valuation product, which combine the advantages of validated tools and techniques used in automated valuation models with the expertise of a professional appraiser to better judge each individual situation."

David Dill, CEO of ValueScape, added "We are thrilled with the upside that this partnership represents, and are looking forward to benefiting from MDA's data assets, knowledge, and support in realizing our vision to advance our appraisal capabilities to a new level of efficiency and accuracy."
