Goodwill and Other Intangible Assets

6. Goodwill and Other Intangible Assets

Goodwill was $5,984 million as of December 31, 2015 compared with $5,740 million as of December 31, 2014. The $244 million increase in goodwill during 2015 is primarily related to acquisitions, offset in part by the effect of foreign currency translation adjustments related to the goodwill associated with our Canadian operations. See Notes 19 and 21 for additional information.

As discussed more fully in Note 3, we perform our annual impairment test of our goodwill balances using a measurement date of October 1. We will also perform interim tests if an impairment indicator exists such that the fair value of a reporting unit could potentially be less than its carrying amount. We did not encounter any events or changes in circumstances that indicated that an impairment was more likely than not during interim periods in 2015, 2014 or 2013.

 

Our other intangible assets as of December 31, 2015 and 2014 were comprised of the following (in millions):

Amortization expense for other intangible assets was $76 million for 2015, $78 million for 2014 and $80 million for 2013. At December 31, 2015, we had $18 million of licenses, permits and other intangible assets that are not subject to amortization, because they do not have stated expirations or have routine, administrative renewal processes. Additional information related to other intangible assets acquired through business combinations is included in Note 19. As of December 31, 2015, expected annual amortization expense related to other intangible assets is $76 million in 2016; $67 million in 2017; $61 million in 2018; $54 million in 2019 and $47 million in 2020.
