The increase in goodwill in the Beverage Packaging segments and in Other is related to the acquisition of Rexam discussed in Note 4. The decrease of goodwill in business dispositions represents goodwill associated the sale of the Ball portion of the Divestment Business. As a result of the divestiture to Ardagh of certain Ball assets in Brazil and Europe, the company performed goodwill impairment tests of these reporting units before and after the divestment. No impairment was identified. At June 30, 2016, the goodwill associated with the acquired Rexam business was recorded in other. During the third quarter the company moved goodwill out of other and into each respective segment as shown above.

The company’s annual goodwill impairment test completed in the fourth quarter of 2015 indicated the fair value of the beverage packaging, Asia (Beverage Asia) reporting unit exceeded its carrying amount by approximately 25 percent. The current industry supply of beverage packaging exceeds demand in China, resulting in pricing pressure and negative impacts on the profitability of our Beverage Asia reporting unit. If it becomes an expectation that this oversupply situation will continue for an extended period of time, the company may be required to record a noncash impairment charge for some or all of the goodwill associated with the Beverage Packaging Asia Pacific reporting unit, the total balance of which was $78 million at September 30, 2016.
