MDA to provide US property insurance carrier with validated property information

Richmond, B.C. - MacDonald, Dettwiler and Associates Ltd. (TSX: MDA), a provider of essential information solutions, announced today that one of the top ten U.S. homeowners insurance carriers has entered into an agreement with MDA subsidiary Marshall Swift / Boeckh (MSB), to integrate MSB's InterChange™ database into its policy quoting and issuance system for improved point-of-sale processing. The agreement provides a per-transaction fee to MDA for each record matched to the client's specific application program.

InterChange draws on MDA's combined suite of property information sources in the U.S. The first release of InterChange involved batch processing of records matched to insurance books of property business. This latest release now puts the data, through web access, in the hands of users at the time insurance is first written. Through proprietary screening, scoring, and amalgamation techniques, aggregated single-family home characteristics data is validated for use by property insurers. Data validation allows homeowners insurers to more accurately determine insurable values and premiums, which improves and streamlines the acquisition of new home insurance policies. 'InterChange solves an important data collection problem for property insurers and expands the company's overall strategy to be the center of all property insurance transactions,' stated Peter Wells, President of MDA subsidiary MSB, 'and we are very pleased to be providing this top homeowners insurance carrier with the data needed to complete better replacement cost estimates'.
