In August 2016, we sold the rights to use of the Comet brand in certain geographic areas (see Note 8 below for further information) and reduced goodwill by $0.6 million as a result.

On July 7, 2016, we completed the sale of Pediacare, New Skin and Fiber Choice (see Note 3 above for further details) for $40.0 million plus the cost of inventory and received $40.1 million including preliminary inventory, less certain immaterial holdbacks, and reduced goodwill by $2.9 million as a result. In addition, as discussed in Note 3, in connection with this sale, the buyer exercised its option to purchase the Dermoplast brand. The sale of Dermoplast was completed on December 30, 2016 and, as a result, we reduced goodwill by $5.5 million.

On December 28, 2016, we completed the sale of the e.p.t brand and, as a result, we reduced goodwill by $1.4 million.

In addition, in December 2016, we received $1.4 million as a result of an arbitration associated with the DenTek acquisition. As a result, we reduced goodwill by $2.8 million, including other post-closing adjustments of $1.4 million.

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 29, 2016, during our annual test for goodwill impairment, there were no indicators of impairment under the analysis. Accordingly, no impairment charge was recorded in fiscal 2016. 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 29, 2016, 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, increases in 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, 2016, no events have occurred that would indicate potential impairment of goodwill.
