Goodwill and Other Intangible Assets

        Intangible assets include both indeterminable-lived residual goodwill and determinable-lived identifiable intangible assets. Intangible assets with a determinable life primarily include intellectual property, consisting of patents, trademarks, and unpatented technology, as well as customer relationships. Recoverability estimates range from 1 to 50 years and costs are generally amortized on a straight-line basis. An evaluation of the remaining useful life of determinable-lived intangible assets is performed on a periodic basis and when events and circumstances warrant an evaluation.

        At fiscal year end 2015, we had seven reporting units, six of which contained goodwill. There are two reporting units in each of the Transportation Solutions and Industrial Solutions segments, and three reporting units in the Communications Solutions segment. When changes occur in the composition of one or more reporting units, goodwill is reassigned to the reporting units affected based on their relative fair values.

        Goodwill impairment is evaluated by comparing the carrying value of each reporting unit to its fair value on the first day of the fourth fiscal quarter of each year or whenever we believe a triggering event requiring a more frequent assessment has occurred. In assessing the existence of a triggering event, management relies on a number of reporting-unit-specific factors including operating results, business plans, economic projections, anticipated future cash flows, transactions, and market place data. There are inherent uncertainties related to these factors and management's judgment in applying these factors to the impairment analysis.

        When testing for goodwill impairment, we perform a step I goodwill impairment test to identify potential impairment by comparing the fair value of a reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, goodwill may be impaired and a step II goodwill impairment test is performed to measure the amount of impairment, if any. In the step II goodwill impairment test, we compare the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of reporting unit goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess. The implied fair value of goodwill is determined in a manner consistent with how goodwill is recognized in a business combination. We allocate the fair value of a reporting unit to all of the assets and liabilities of that unit, including intangible assets, as if the reporting unit had been acquired in a business combination. Any excess of the fair value of a reporting unit over the amounts assigned to its assets and liabilities is the implied fair value of goodwill.

        Fair value estimates used in the step I goodwill impairment tests are calculated using an income approach based on the present value of future cash flows of each reporting unit. The income approach generally has been supported by guideline analyses (a market approach). These approaches incorporate a number of assumptions including future growth rates, discount rates, income tax rates, and market activity in assessing fair value and are reporting unit specific. Changes in economic and operating conditions impacting these assumptions could result in goodwill impairments in future periods.

About Goodwill & Intangibles Disclosures

Goodwill and intangible asset disclosures reveal the premium paid in acquisitions and how management assesses whether that premium retains its value. Since goodwill is no longer amortized under US GAAP, the annual impairment test is the only mechanism that adjusts carrying values downward — making the assumptions behind that test critically important for investors.

Key signals: a history of goodwill impairments suggests management consistently overpays for acquisitions. Watch the gap between reporting unit fair value and carrying amount — when fair value exceeds carrying amount by less than 10-20%, a small decline in business performance could trigger a write-down. For finite-lived intangibles, examine useful life assumptions across customer relationships, technology, and trade names; aggressive estimates inflate near-term earnings. Compare total intangibles-to-total-assets ratios against peers to assess acquisition dependency. Rising goodwill as a percentage of equity can signal balance sheet fragility.
