Goodwill is not amortized as it is estimated to have an indefinite life. At least annually, the Company is required to test goodwill at the reporting unit level for potential impairment, and, if impaired, write down to fair value based on the present value of discounted cash flows. The Company’s reporting units evaluated for potential impairment were the U.S., Europe and Asia Pacific, which reflect the level of internal reporting the Company uses to manage its business and operations. The three reporting units are consistent with the operating segments reported as there is no discrete financial information available for the subsidiaries within each operating segment. The Company performed its annual goodwill impairment test during the fourth quarter of fiscal 2015, consistent with the timing of previous years, at which time it was determined that there were no indications of impairment, with the fair value of each of the Company’s reporting units significantly exceeding carrying value. Goodwill acquired during the first nine months of fiscal 2016 of $188.4 million represents the excess of the preliminary purchase price over the fair value of the net tangible and intangible assets from the Portware acquisition completed in October 2015.
