The Company evaluates each quarter if facts and circumstances indicate that it is more-likely-than-not that the fair value of its reporting units is less than their carrying value, which would require the Company to perform an interim goodwill impairment test. Indicators the Company evaluates to determine whether an interim goodwill impairment test is necessary include, but are not limited to, (i) a sustained decrease in share price or market capitalization as of any fiscal quarter end, (ii) changes in macroeconomic or industry environments, (iii) the results of, and the amount of time passed since, the last goodwill impairment test, and (iv) the long-term expected financial performance of its reporting units.
