6. Goodwill

We review goodwill for impairment annually during the first quarter of each fiscal year, or more frequently if impairment indicators arise. The review of impairment consists of either using a qualitative approach to determine whether it is more likely than not that the fair value of the assets is less than their respective carrying values or a one-step quantitative impairment test.

The results of the first quarter analysis did not result in an impairment since the fair value of each reporting unit exceeded its carrying value.
