The company’s annual goodwill impairment test completed in the fourth quarter of 2018 indicated the fair value of the metal beverage packaging, Asia Pacific (beverage Asia Pacific), and beverage packaging, AMEA (beverage AMEA), reporting units exceeded their carrying amounts by approximately 11 percent and 15 percent, respectively. 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 Pacific reporting unit. The worsening business climate in Saudi Arabia has resulted in negative impacts to the profitability of our beverage AMEA reporting unit. If it becomes an expectation that these situations will continue for an extended period of time, the company may be required to record noncash impairment charges for some or all of the goodwill associated with the beverage Asia Pacific and beverage AMEA reporting units, the total balances of which were $78 million and $101 million, respectively, at March 31, 2019. Of the goodwill associated with the beverage Asia Pacific reporting unit, $51 million relates to the China beverage packaging business and is reported in assets held for sale at March 31, 2019. The goodwill balance of $27 million within the beverage Asia Pacific reporting unit not reported in assets held for sale relates to the remaining business of beverage Asia Pacific. See Note 4 for further details regarding Ball’s planned sale of its metal beverage packaging business in China.
