(a) Amount relates to a measurement period adjustment recorded during the three months ended September 30, 2017, associated with our Fleet acquisition.

As discussed in Note 2, on January 26, 2017, we completed the acquisition of Fleet. In connection with this acquisition, we recorded goodwill of $273.1 million based on the amount by which the purchase price exceeded the fair value of the net assets acquired.

Under accounting guidelines, goodwill is not amortized, but must be tested for impairment annually, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below the carrying amount.

On an annual basis during the fourth quarter of each fiscal year, or more frequently if conditions indicate that the carrying value of the asset may not be recoverable, management performs a review of the values assigned to goodwill and tests for impairment. At February 28, 2017, during our annual test for goodwill impairment, there were no indicators of impairment under the analysis. Accordingly, no impairment charge was recorded in fiscal 2017. We utilize the discounted cash flow method to estimate the fair value of our reporting units as part of the goodwill impairment test. We also considered our market capitalization at February 28, 2017, which was the date of our annual review, as compared to the aggregate fair values of our reporting units, to assess the reasonableness of our estimates pursuant to the discounted cash flow methodology. The estimates and assumptions made in assessing the fair value of our reporting units and the valuation of the underlying assets and liabilities are inherently subject to significant uncertainties. Consequently, changing rates of interest and inflation, declining sales or margins, increasing competition, changing consumer preferences, technical advances, or reductions in advertising and promotion may require an impairment charge to be recorded in the future. As of December 31, 2017, no events have occurred that would indicate potential impairment of goodwill.
