IMPAIRMENT LOSSES AND IMPAIRMENT LOSS REVERSALS
In 2009, MTU Maintenance Canada Ltd., Richmond, Canada, operating under contract to Chromalloy Gas Turbine LLC, made a successful bid for a major U.S. Air Force contract for maintenance of its KC-10 tanker fleet. This contract ensures a profitable future for MTU Maintenance Canada. The carrying amounts of the intangible assets and property, plant and equipment for which impairment losses were recognized in the financial years 2005 - 2007 were reassessed in the light of the company’s improved situation, and compared with the respective recoverable amounts. For certain items of property, plant and equipment, the recoverable amount exceeded the carrying amount, necessitating an impairment loss reversal in the financial year 2009 amounting to € 1.1 million to increase the carrying amount accordingly. In the financial year 2010, no impairment losses were recognized on intangible assets, financial assets, or property, plant and equipment.
Information on the components of these assets is provided in Part V. (Segment Information).
