As of September 30, 2021 and December 31, 2020, accumulated impairment charges in the International and Other segment totaled $123.1 million.

The reduction of $1.0 million in the carrying amount of goodwill for Domestic Operations 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 addition of $11.9 million in the carrying amount of goodwill in International and Other relates to the acquisition of the remaining 50% interest in an equity method investment in which the Company previously owned a 50% interest. The allocation of goodwill is preliminary and is based on current estimates and currently available information, and is subject to revision based final allocations of the purchase price to the identifiable assets and liabilities acquired.
