. INTANGIBLE ASSETS

FactSet’s identifiable intangible assets consist of acquired content databases, client relationships, software technology, non-compete agreements and trade names resulting from previous acquisitions, which have been fully integrated into the Company’s operations. The weighted average useful life of FactSet’s acquired identifiable intangible assets at

February 28, 2018

was

11.5

years. The Company amortizes intangible assets over their estimated useful lives, which are evaluated quarterly to determine whether events and circumstances warrant a revision to the remaining period of amortization. There have been

changes to the estimate of the remaining useful lives during the

first

six

months of fiscal

2018.

Amortizable intangible assets are tested for impairment, if indicators of impairment are present, based on undiscounted cash flows, and, if impaired, written down to fair value based on discounted cash flows.

impairment of intangible assets has been identified during any of the periods presented. The intangible assets have

assigned residual values.

The gross carrying amounts and accumulated amortization totals related to the Company’s identifiable intangible assets are as follows:
