We annually review the estimated lives and methods used to amortize our other intangible assets. The actual amounts of amortization expense may differ materially from our estimates, depending on the results of our annual reviews.
Substantially, all of our goodwill was derived from CenturyLink's acquisition of us where the purchase price exceeded the fair value of the net assets acquired.
We assess our goodwill for impairment annually, or, under certain circumstances, more frequently, such as when events or changes in circumstances indicate there may be impairment. We are required to write down the value of goodwill only when our assessment determines the recorded amount of goodwill exceeds the implied fair value. Our annual impairment assessment date for goodwill is October 31, at which date we assessed goodwill at our reporting units. In reviewing the criteria for reporting units, we have determined that we are one reporting unit.
We compare our estimated fair value of equity to our carrying value of equity. If the estimated fair value of our equity is greater than the carrying value of our equity, we conclude that no impairment exists. If the estimated fair value of our equity is less than our carrying value of our equity, a second calculation is required in which the implied fair value of goodwill is compared to our carrying value of goodwill. If the implied fair value of goodwill is less than our carrying value of goodwill, goodwill must be written down to the implied fair value.
At October 31, 2017, we utilized a Level 3 valuation technique to estimate the fair value of our equity by considering both a market approach and a discounted cash flow method. The market approach method includes the use of comparable multiples of publicly traded companies whose services are comparable to ours. The discounted cash flow method is based on the present value of projected cash flows and a terminal value, which represents the expected normalized cash flows of the reporting unit beyond the cash flows from the discrete projection period. Based on our assessment performed with respect to our reporting unit as described above, we concluded that our goodwill was not impaired as of that date. As of October 31, 2016 and 2015, based on our assessments performed, we concluded that our goodwill was not impaired as of those dates.
