During the third quarter of 2016, the company made certain segment realignments as a result of the Rexam acquisition and sale of the Divestment Business. As a result, goodwill by segment has been retrospectively adjusted to conform to the current year presentation. No impairment charges were considered necessary or recorded for the company’s existing reporting units.

The company’s annual goodwill impairment test completed in the fourth quarter of 2016 indicated the fair value of the metal beverage packaging, Asia (Beverage Asia) reporting unit exceeded its carrying amount by approximately 23 percent. The current supply of metal 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 Asia reporting unit, the total balance of which was $78 million at December 31, 2016.
