Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Other Intangible Assets

A summary of the change in the carrying amount of goodwill for our segments (see Note 19, “Segment Information”) for 2017 and 2016 is as follows:



	Commercial and Specialty Business			Government Business		Other		Total
Balance as of January 1, 2016	$	11,818.9		$	5,743.3	$	—	$	17,562.2
Other adjustments	(1.0		)	—		—		(1.0		)
Balance as of December 31, 2016	11,817.9			5,743.3		—		17,561.2
Acquisitions	—			1,658.5		11.5		1,670.0
Balance as of December 31, 2017	$	11,817.9		$	7,401.8	$	11.5	$	19,231.2
Accumulated impairment as of December 31, 2017	$	(41.0	)	$	—	$	—	$	(41.0	)

The increase in goodwill in 2017 was primarily due to the acquisition of HealthSun in December 2017. For additional information regarding this acquisition, see Note 3, "Business Acquisitions".

As required by FASB guidance, we completed annual impairment tests of existing goodwill and other intangible assets with indefinite lives during 2017, 2016 and 2015. We perform these annual impairment tests during the fourth quarter. FASB guidance also requires interim impairment testing to be performed when potential impairment indicators exist. These tests involve the use of estimates related to the fair value of goodwill and intangible assets with indefinite lives and require a significant degree of management judgment and the use of subjective assumptions. The fair values were estimated using the projected income and market valuation approaches, incorporating Level III internal estimates for inputs, including, but not limited to, revenue projections, income projections, cash flows and discount rates. We did not incur any impairment losses in 2017, 2016 or 2015, as the estimated fair values of our reporting units were substantially in excess of their carrying values.

The components of other intangible assets as of December 31, 2017 and 2016 are as follows:
