Goodwill and Intangible Assets:

Goodwill associated with the Company’s purchase of Monitor in August 2017, Bowers in June 2016 and other past acquisitions totaled $38.2 million at September 30, 2018 and December 31, 2017. The Monitor acquisition is more fully described in the Business Acquisitions footnote. Impairment exists when a reporting unit’s carrying value of goodwill exceeds its fair value, which is determined through a two-step impairment test. Management performs goodwill impairment testing on an annual basis as of September 30. The fair value of the reporting unit is determined based on a discounted cash flow model.
