Indefinite lived intangible assets - Carrying value

	2018		2017
Trade Names	$	1,483.6	$	1,484.8

Intangible amortization expense was $17.8 and $14.4 for the second quarter of 2018 and 2017, respectively. Intangible amortization expense amounted to $35.8 and $28.3 for the first six months of 2018 and 2017, respectively. The Company estimates that intangible amortization expense related to amortizable intangible assets held as of June 30, 2018 will be approximately $71.0 in 2018 and declining over the next five years from approximately $70.0 to $60.0 annually.

The Company determined that the carrying value of all trade names as of December 31, 2017, was recoverable based upon the forecasted cash flows and profitability of the brands. There is a personal care trade name that, based on recent performance, has experienced sales and profit declines that have eroded a significant portion of the excess between fair and carrying value which could potentially result in an impairment of the asset. In 2017, this excess was reduced to approximately $34.0 or 12% in large part due to an increased competitive market environment therefore resulting in reduced cash flow projections. The Company continues to monitor performance and should there be any significant change in forecasted assumptions or estimates, including sales, profitability and discount rate, the Company may be required to recognize an impairment charge.

The carrying amount of goodwill is as follows:

	Consumer		Consumer		Specialty
	Domestic		International		Products		Total
Balance at December 31, 2017	$	1,632.1	$	223.3	$	103.5	$	1,958.9
Passport acquired goodwill		0.0		0.0		32.5		32.5
Waterpik adjustment		1.1		0.4		0.0		1.5
Balance at June 30, 2018	$	1,633.2	$	223.7	$	136.0	$	1,992.9

The goodwill and other intangible assets associated with the Waterpik and Passport acquisitions are not deductible for U.S. tax purposes. In connection with its annual goodwill impairment test performed in the beginning of the second quarter of 2018, the Company determined that the estimated fair value substantially exceeded the carrying values of all reporting units.
