The Company has six (6) reporting units for which an annual goodwill impairment assessment was performed as of January 1, 2018. The Company concluded that all of the reporting units’ fair value exceeded their carrying amounts by at least 30% as of January 1, 2018. The fair values of the reporting units in accordance with the goodwill impairment test were determined using the Income and Market approaches. The Income approach employs the discounted cash flow method reflecting projected cash flows expected to be generated by market participants and then adjusted for time value of money factors. The Market approach utilizes an analysis of comparable publicly traded companies.

The techniques used in the Company's impairment tests have incorporated a number of assumptions that the Company believes to be reasonable and to reflect known market conditions at the measurement dates. Assumptions in estimating future cash flows are subject to a degree of judgment. The Company makes all efforts to forecast future cash flows as accurately as possible with the information available at the measurement date. The Company evaluates the appropriateness of its assumptions and overall forecasts by comparing projected results of upcoming years with actual results of preceding years. Key Level 3 based assumptions relate to pricing trends, inventory costs, customer demand, and revenue growth. A number of benchmarks from independent industry and other economic publications were also used. Changes in future results, assumptions, and estimates after the measurement date may lead to an outcome where additional impairment charges would be required in future periods. Specifically, actual results may vary from the Company’s forecasts and such variations may be material and unfavorable, thereby triggering the need for future impairment tests where the conclusions may differ in reflection of prevailing market conditions.

At December 31, 2018 and June 30, 2018, accumulated goodwill impairment losses subsequent to fiscal year 2002 totaled $64,794 related to the Service Center Based Distribution segment and $36,605 related to the Fluid Power & Flow Control segment.
