⁽¹⁾ During the year ended December 31, 2017 and 2016, the Company transferred a component of one reporting unit to another reporting unit. An interim impairment analysis was performed both before and after the transfer, noting no impairment indicators were present.

As a result of the annual impairment test performed as of October 1, 2017, the Company recognized a partial impairment of goodwill of $3,238 relating to two of the Company’s reporting units. See Note 2 of the Notes to the Consolidated Financial Statements herein for further information. Additionally, during 2017, the Company wrote off goodwill of $17,593 related to the sale of certain subsidiaries. This write off is included in other income (expense).

During the third quarter of 2016, there was a change to the Company’s reporting units. This change, coupled with a decline in operating performance required the Company to perform interim goodwill testing on one of its experiential reporting units. Additionally, a triggering event occurred during the third quarter of 2016 that required the Company to perform interim goodwill testing on one non-material reporting unit. This interim impairment analysis resulted in a partial impairment of goodwill of $27,893 and $1,738 relating to the experiential reporting unit and non-material reporting unit, respectively.

For the 2016 annual impairment test, a partial impairment of goodwill of $18,893 in one of the Company’s strategic communications reporting units. The fair value for all other reporting units were in excess of their respective carrying amounts and as a result there was no additional impairment of goodwill. Additionally, in the third quarter of 2016, the Company sold its ownership interests in a subsidiary to the noncontrolling shareholders, resulting in a write off of goodwill of $764.

The total accumulated goodwill impairment charges are $98,645 through December 31, 2017.
