As discussed in Note 2, we completed two acquisitions during the year ended March 31, 2015. On September 3, 2014, we completed the acquisition of Insight and recorded goodwill of $96.3 million, reflecting the amount by which the purchase price exceeded the preliminary estimate of fair value of net assets acquired, after giving effect to the following adjustments. During the quarter ended June 30, 2015, we increased goodwill by $0.3 million for certain immaterial items. During the quarter ended December 31, 2015, we decreased goodwill by $7.2 million, as we received that amount from escrow pursuant to an arbitrator's ruling in December 2015 related to a disputed working capital calculation, as determined under GAAP, associated with the Insight acquisition, which is clearly and directly related to the purchase price. Additionally, on April 30, 2014, we completed the acquisition of the Hydralyte brand and recorded goodwill of $1.2 million, reflecting the amount by which the purchase price exceeded the preliminary estimate of fair value of the net assets acquired.

As further discussed in Note 7, in December 2014, we completed a transaction to sell rights to use of the Comet brand in certain Eastern European countries to a third-party licensee. As a result, we recorded a gain on sale of $1.3 million and reduced the carrying value of our intangible assets and goodwill.

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.

We utilize the discounted cash flow method to estimate the fair value of our reporting units as part of the goodwill impairment test and the excess earnings method to estimate the fair value of our individual indefinite-lived intangible assets. We also considered our market capitalization at February 28, 2015, 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.

At February 28, 2015, during our annual test for goodwill impairment, there were no indicators of impairment under the analysis. Accordingly, no impairment charge was recorded in fiscal 2015. As of December 31, 2015, there have been no triggering events that would indicate potential impairment of goodwill.
