The carrying amount of goodwill, by operating segment is as follows:



(In thousands)	National Networks			International and Other		Total
December 31, 2017	$	239,759		$	455,399	$	695,158

The reduction of $0.3 million in the carrying amount of goodwill for the National Networks is due to the realization of a tax benefit for the amortization of "second component" goodwill at SundanceTV. Second component goodwill is the amount of tax deductible goodwill in excess of goodwill for financial reporting purposes. In accordance with the authoritative guidance at the time of the SundanceTV acquisition, the tax benefits associated with this excess are applied to first reduce the amount of goodwill, and then other intangible assets for financial reporting purposes, if and when such tax benefits are realized in the Company's tax returns.

The following tables summarize information relating to the Company's identifiable intangible assets:
