Gross goodwill, accumulated impairments, and accumulated divestiture related write-offs were determined beginning January 1, 2012, when a change in accounting requirements resulted in goodwill being assessed for impairment rather than being amortized. Gross goodwill of $200.0 million with accumulated impairments and accumulated divestiture-related write-offs of $114.1 million and $85.9 million, respectively, were previously allocated to the non-strategic segment, resulting in $0 net goodwill allocated to the non-strategic segment as of June 30, 2017 and December 31, 2016. The regional banking and fixed income segments do not have any accumulated impairments or divestiture related write-offs. The following is a summary of goodwill by reportable segment included in the Consolidated Condensed Statements of Condition as of June 30, 2017 and December 31, 2016.
