Long-Lived Assets	Long-Lived Assets Depreciation and Amortization Expense We recognized depreciation expense of $10.3 million and $20.6 million in the three and six months ended June 28, 2020, respectively. We recognized depreciation expense of $9.9 million and $20.0 million in the three and six ended June 30, 2019, respectively. We recognized amortization expense related to our intangible assets of $16.4 million and $32.9 million in the three and six months ended June 28, 2020, respectively. We recognized amortization expense related to our intangible assets of $19.1 million and $37.4 million in the three and six ended June 30, 2019, respectively. Interim Impairment Test Due to equity market conditions during the three and six months ended June 28, 2020, we conducted an interim impairment test. We determined that the carrying values of our definite-lived assets were recoverable; therefore, we did not record any impairment charges related to these assets. Goodwill is tested for impairment at the reporting unit level, and we conducted an interim impairment test for all of our reporting units. A reporting unit is an operating segment, or a business unit one level below an operating segment if discrete financial information for that business is prepared and regularly reviewed by segment management. However, components within an operating segment are aggregated as a single reporting unit if they have similar economic characteristics. We determined that each of our reportable segments (Enterprise Solutions and Industrial Solutions) represents an operating segment. Within those operating segments, we have identified reporting units based on whether there is discrete financial information prepared that is regularly reviewed by segment management. When we evaluate goodwill for impairment using a quantitative assessment, we compare the fair value of each reporting unit to its carrying value. We determine the fair value using an income approach. Under the income approach, we calculate the fair value of a reporting unit based on the present value of estimated future cash flows using growth rates and discount rates that are consistent with current market conditions in our industry. If the fair value of the reporting unit exceeds the carrying value of the net assets including goodwill assigned to that unit, goodwill is not impaired. If the carrying value of the reporting unit’s net assets including goodwill exceeds the fair value of the reporting unit, then we record an impairment charge based on that difference. In addition to the income approach, we calculate the fair value of our reporting units under a market approach. The market approach measures the fair value of a reporting unit through analysis of financial multiples of comparable businesses. Consideration is given to the financial conditions and operating performance of the reporting unit being valued relative to those publicly-traded companies operating in the same or similar lines of business. Significant judgment is required when applying the market approach as there is a range of financial multiples of comparable businesses. Based on our interim goodwill impairment test, we determined that the fair values of the reporting units were in excess of the carrying values; therefore, we did not record any goodwill impairment. The excess of the fair values over the carrying values of our reporting units ranged from 2% - 206%. The significant assumptions used to estimate fair values included sales growth, profitability, and related cash flows, along with cash flows associated with taxes and capital spending. The discount rate used to estimate fair value was risk adjusted in consideration of the economic conditions in effect at the time of the impairment test. We also considered assumptions that market participants may use. In our quantitative assessments, the discount rates ranged from 10.0% to 17.0%, the 2020 to 2029 compounded annual revenue growth rates ranged from 2.0% to 8.3%, and the revenue growth rates beyond 2029 ranged from 2.0% to 3.0%. By their nature, these assumptions involve risks and uncertainties. Furthermore, uncertainties associated with current market conditions increase the inherent risk associated with using an income approach to estimate fair values. While we have adjusted our key assumptions to reflect the current economic conditions, we have also assumed that economic conditions will improve beyond 2020. If current conditions persist and actual results are different from our estimates or assumptions, we may have to recognize an impairment charge that could be material. We also tested our indefinite-lived intangible assets, which consist primarily of trademarks, for impairment during the quarter ended June 28, 2020. We performed a quantitative assessment for each of our indefinite-lived trademarks using a relief from royalty methodology and compared the fair value to the carrying value. We determined that none of our trademarks were impaired as of June 28, 2020. Significant assumptions to determine fair value included sales growth, royalty rates, and discount rates.
