We perform an impairment assessment of our goodwill balances as of October 1 of each year. Goodwill impairment testing is performed at the level below the business segments (referred to as a reporting unit). After consideration of the LifeWorks Disposition, management has concluded that we have one reporting unit. Please refer to Note 3, “Discontinued Operations,” for further discussion of the LifeWorks Disposition.

As of January 1, 2017, we elected early adoption of ASU No. 2017-04, “Intangibles-Goodwill and Other,” which simplifies the subsequent measurement of goodwill by eliminating Step 2 of the goodwill impairment test. We performed the annual impairment quantitative test as of October 1, 2017, and concluded that the fair value exceeded the carrying amount by greater than 50%.
