Goodwill is reviewed for possible impairment at least annually, or more frequently upon the occurrence of an event, or when circumstances indicate that a reporting unit's carrying amount is greater than its fair value. The Company performed a qualitative assessment during the fourth quarter of both 2017 and 2016 and determined that there were no indicators of impairment. Accordingly, the Company did not perform the two-step goodwill impairment test for any reporting unit in both 2017 and 2016.

In 2015, the Company performed a review and test of goodwill and determined that the fair value exceeded the carrying amount for all of our reporting units with goodwill.

The Company performed a qualitative review of its indefinite lived intangible assets in the fourth quarter of 2017 and 2016 and determined that there were no indicators of impairment.

In 2015, the Company performed a review and test for impairment of indefinite lived intangible assets. The fair value of the indefinite lived intangible assets were calculated using a discounted cash flow analysis, and resulted in the fair value exceeding the carrying value.

See Note 2. "Fair Value of Financial Instruments" for a discussion of the fair value measures used in determining these impairment charges.
