MDA Introduces Tax Information Product For Commercial Properties In U.S.

Richmond, B.C. - MacDonald, Dettwiler and Associates Ltd. (TSX: MDA), a provider of essential information solutions, announced today that its U.S. subsidiary Marshall & Swift/Boeckh (MSB) has launched a new information product aimed at tax advisors and accounting firms serving commercial property owners. The product, called CostSeg-Pro, provides for automated segregation of those capital cost components that can be depreciated faster, which in turn is used to lower the taxable cost base of commercial properties.

CostSeg-Pro offers cost segregation practitioners a web-based access information solution for preparing standardized cost segregation studies that meet the guidelines of the U.S. Internal Revenue Service (IRS). The product uses MSB building data and cost calculation methods, which are quoted in the IRS Audit Techniques Guide as an acceptable standard for cost segregation purposes.

In excess of 200,000 commercial properties purchased after 1986 and valued at between $1,000,000 and $5,000,000 are eligible candidates for cost segregation studies, and total federal and income tax savings from applying cost segregation can add up to 10-20% of the property value over the life of a property.

Jim Thornton, general manager of MSB, stated: "Over the years MDA's industry-standard and IRS accepted building cost data has been used extensively by cost segregation practitioners in conducting their studies. With the launch of CostSeg-Pro we now offer those cost segregation practitioners a convenient web-based solution to conduct those studies more efficiently and produce the results in a pre-approved format, saving them time and money".
