The Company evaluates the carrying value of goodwill on an annual basis or more frequently when events and circumstances warrant such an evaluation. In conducting this analysis, the Company uses the income approach to compare the reporting unit's carrying value to its indicated fair value. Fair value is determined primarily by using a discounted cash flow methodology that requires considerable management judgment and long-term assumptions and is considered a Level 3 (unobservable) fair value determination in the fair value hierarchy (see Note 13) below.
