Long-Lived Assets
Note 6. Long-Lived Assets

Goodwill and other intangible assets: We account for goodwill and intangible assets in accordance with ASC 350, Goodwill and Other Intangible Assets.  Under these provisions, goodwill is not amortized but is tested for impairment on at least an annual basis.  Impairment testing is required more often than annually if an event or circumstance indicates an impairment or a decline in value may have occurred.  Such circumstances could include, but are not limited to, a worsening trend of orders and sales without a corresponding way to preserve future cash flows or a significant decline in our stock price. In conducting our impairment testing, we compare the fair value of each of our business units (reporting unit) to the related carrying value.  If the fair value of a reporting unit exceeds its carrying value, goodwill is not impaired.  If the carrying value of a reporting unit exceeds its fair value, an impairment loss is measured and recognized.  

We utilize an income approach to estimate the fair value of each reporting unit.  We selected this method because we believe it most appropriately measures our income producing assets.  We considered using the market approach and cost approach, but concluded they were not appropriate in valuing our reporting units given the lack of relevant and available market comparisons.  The income approach is based on the projected cash flows, which are discounted to their present value using discount rates which consider the timing and risk of the forecasted cash flows.  We believe that this approach is appropriate because it provides a fair value estimate based upon the reporting units’ expected long-term operating cash performance.  This approach also mitigates the impact of the cyclical trends occurring in the industry.  Fair value is estimated using internally-developed forecasts and assumptions.  The discount rate used is the average estimated value of a market participant’s cost of capital and debt, derived using customary market metrics. Other significant assumptions include terminal value margin rates, future capital expenditures, and changes in future working capital requirements.  We also compare and reconcile our overall fair value to our market capitalization.  Although there are inherent uncertainties related to the assumptions used and to our application of these assumptions to this analysis, we believe the income approach provides a reasonable estimate of the fair value of our reporting units.  The foregoing assumptions to a large degree were consistent with our long-term performance, with limited exceptions.  We believe our future investments for capital expenditures as a percent of revenue will remain similar to the historical rates as a percentage of sales in future years. Our investments are expected to relate to equipment replacements and new product line manufacturing equipment needs, and to keep our information technology infrastructure robust. These assumptions could deviate materially from actual results.

We perform an analysis of goodwill on an annual basis, and is tested for impairment more frequently if events or changes in circumstances indicate that an asset might be impaired. We complete this annual analysis during our third quarter of each fiscal year, based on the goodwill amount as of the first business day of our third quarter in fiscal 2016, 2015, and 2014.  The result of our analysis indicated no goodwill impairment existed for fiscal years 2016, 2015, and 2014.

During the fourth quarter of fiscal 2016, we performed an interim goodwill impairment analysis due to economic conditions causing slowing orders. The results of our analysis indicated no goodwill impairment was necessary.

The changes in the carrying amount of goodwill related to each reportable segment for the fiscal year ended April 30, 2016 were as follows:

As required by ASC 350, intangibles with finite lives are amortized.  We evaluate indefinite lived assets for impairment annually and whenever events or changes in circumstances indicate their carrying value may not be recoverable.  The net value of intangible assets is shown on our consolidated balance sheets.  Estimated amortization expense based on intangibles as of April 30, 2016 is $1,591 for fiscal 2017, $1,492 for fiscal 2018, $1,393 for fiscal 2019, $473 for fiscal 2020, $440 for fiscal 2021, and $2,332 thereafter.

Impairment of long-lived assets:  In the fiscal years ended April 30, 2016, May 2, 2015, and April 26, 2014, the pretax impairment charges for other long-lived assets, including property and equipment, were immaterial. The impairment charges related to technology or equipment obsoleted due to technology improvements or to custom demo equipment with no resale value.  Impairment charges during fiscal 2016, 2015, and 2014 were included primarily in product development and selling expense.
