Indefinite-lived intangible assets

Sale and License of an Intangible Asset

In the third quarter of 2017, the Corporation recorded a $6.0 million nonrecurring gain from the sale and license of an intangible asset, which had a zero carrying value. This nonrecurring gain is reflected in "Gain on sale and license of assets" in the Condensed Consolidated Statements of Comprehensive Income.

Impairment Analysis

The Corporation evaluates its goodwill and indefinite-lived intangible assets for impairment on an annual basis during the fourth quarter or whenever indicators of impairment exist. During the third quarter of 2018, the Corporation determined a triggering event occurred for one of the Corporation's reporting units within the office furniture segment due to lower projected operating results for the year. Accordingly, interim quantitative impairment tests were performed for goodwill and an indefinite-lived intangible asset. The tests indicated no impairment. In conjunction with the interim impairment tests, the Corporation also tested the recoverability of the remaining long-lived assets for the reporting unit and found no impairments.

The projections used in the impairment model reflected management's assumptions regarding revenue growth rates, economic and market trends, cost structure, investments required for operational transformation, and other expectations about the anticipated short-term and long-term operating results of the reporting unit. The Corporation assumed a discount rate of 13.5 percent, near term growth rates ranging from 3 percent to 12 percent, and a terminal growth rate of 3 percent. Holding other assumptions constant, a 100 basis point increase in the discount rate would result in a $3.8 million decrease in the estimated fair value of the reporting unit. Holding other assumptions constant, a 100 basis point decrease in the long-term growth rate would result in a $1.8 million decrease in the estimated fair value of the reporting unit. Neither of these scenarios individually would result in an impairment of the reporting unit's goodwill. There is $19.6 million of goodwill associated with this reporting unit as of September 29, 2018.
