At December 31, 2017, the Company assessed qualitative factors to determine if it was necessary to perform either the two-step quantitative impairment test related to the carrying amount of its goodwill or quantitative impairment tests related to the carrying amounts of its identified intangible assets not subject to amortization. Based on these assessments, the Company determined that it was not necessary to perform either the two-step quantitative impairment test related to the carrying amount of its goodwill nor the quantitative impairment tests related to the carrying amounts its identified intangible assets not subject to amortization at that date.

At December 31, 2017, the Company assessed if events or changes in circumstances indicated that the aggregate carrying amount of its identified intangible assets subject to amortization might not be recoverable. There were no indicators present that required the Company to test the recoverability of the aggregate carrying amount of its identified intangible assets subject to amortization at that date.
