The Company completed an annual impairment review at each fiscal year-end and concluded there was no impairment of goodwill.  In performing the impairment reviews, the Company estimated the fair values of the reporting units using a present value method that discounted future cash flows.  Such valuations are sensitive to assumptions associated with cash flow growth, discount rates, terminal value and the aggregation of reporting unit components.  The Company further assessed the reasonableness of these estimates by considering relevant market multiples.

The following table summarizes acquired intangible assets by segment.  Other acquired intangible assets include parts manufacturer regulatory approvals, proprietary technology, patents and noncompete agreements.

The Company performed annual impairment tests on its indefinite-lived intangible assets at each fiscal year-end using the relief-from-royalty method to determine the fair value of its trademarks and trade names.  There was no impairment as the fair value was greater than the carrying value for these indefinite-lived intangible assets as of these dates.  In addition, the Company reassessed the useful lives and classification of identifiable finite-lived intangible assets at each year-end and determined that they continue to be appropriate.

The following tables summarize actual amortization expense for the past three fiscal years and estimated amortization expense for the next five fiscal years.
