Amortization expense related to other intangible assets was $6 million, $2 million and $1 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Goodwill

Goodwill represents the total consideration paid in excess of the fair value of the net tangible and identifiable intangible assets acquired and the liabilities assumed in acquisitions. Goodwill has an indefinite life and is not amortized but is reviewed for impairment under the provisions of accounting standards for goodwill. All goodwill is related to the North America reporting segment, which is comprised of two reporting units. We performed the required annual impairment review of our recorded goodwill for our reporting units as of October 1, 2016 and determined that the fair value of our reporting units was not less than their relative carrying values. As of December 31, 2016, goodwill of approximately $56 million was deductible for federal income tax purposes.

The following table details the changes in carrying value of goodwill (in millions):



	Total
Balance as of December 31, 2014	$	274
Goodwill related to acquisitions	27
Balance as of December 31, 2015	301
Goodwill related to acquisitions	1
Balance as of December 31, 2016	$	302
