Goodwill and Identifiable Intangible Assets, net

Goodwill

We review goodwill for impairment on a reporting unit basis annually during the fourth quarter of each year, using a measurement date of October 1st, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. The Company performed a qualitative assessment by reporting unit as of October 1, 2018, during the fourth quarter of 2018. This assessment included consideration of key factors including macroeconomic conditions, industry and market considerations, cost factors, and other relevant entity-and reporting unit-specific events. We concluded it was more likely than not that the fair value of each reporting unit exceeded its carrying amount. As such, it was not necessary to perform a quantitative goodwill impairment test. There have been no significant events or circumstances affecting the valuation of goodwill subsequent to the qualitative assessment performed as of October 1, 2018.

Allocation of Goodwill to Reporting Segment

The following table shows our goodwill balances by reportable segment:



(In millions)	Food Care			Product Care			Total
Gross Carrying Value at December 31, 2016	$	560.3		$	1,513.0		$	2,073.3
Accumulated impairment	(49.5		)	(140.9		)	(190.4		)
Carrying Value at December 31, 2016	$	510.8		$	1,372.1		$	1,882.9
Acquisition and divestiture	10.1			39.3			49.4
Currency translation	6.0			1.5			7.5
Gross Carrying Value at December 31, 2017	$	576.5		$	1,554.1		$	2,130.6
Accumulated impairment	(49.6		)	(141.2		)	(190.8		)
Carrying Value at December 31, 2017	$	526.9		$	1,412.9		$	1,939.8
Acquisition, purchase price and other adjustments	(0.6		)	18.2			17.6
Currency translation	(6.6		)	(3.2		)	(9.8		)
Gross Carrying Value at December 31, 2018	$	568.9		$	1,568.9		$	2,137.8
Accumulated impairment	(49.2		)	(141.0		)	(190.2		)
Carrying Value at December 31, 2018	$	519.7		$	1,427.9		$	1,947.6

As noted above, it was determined under a qualitative assessment that it was not more likely than not that the fair value of any reporting unit was less than its carrying amount. Therefore, there was no impairment of goodwill. However, if events or circumstances change in future periods, the Company may be required to perform a quantitative test. If we were required to perform a quantitative test, the amount of the impairment charge to be recognized would be the amount by which the carrying value exceeded the estimated fair value at a reporting unit level.

The future occurrence of a potential indicator of impairment, such as a decrease in expected net earnings, adverse equity market conditions, a decline in current market multiples, a decline in our common stock price, a significant adverse change in legal factors or business climates, an adverse action or assessment by a regulator, unanticipated competition, strategic decisions made in response to economic or competitive conditions, or a more likely than not expectation that a reporting unit or a significant portion of a reporting unit will be sold or disposed of, could require an interim assessment for some or all of the reporting units before the next required annual assessment. In the event of significant adverse changes of the nature described above, we might have to recognize a non-cash impairment of goodwill, which could have a material adverse effect on our consolidated financial condition and results of operations.
