Due to a decrease in the Company's stock price, persistently low short-term interest rates, as well as the continued declining trend in transaction-based retail commissions and financial advisers headcount in the PCD, the Company performed an interim goodwill impairment analysis as of August 31, 2016, which did not result in any impairment charges. The PCD reporting unit had an estimated fair value that was in excess of its carrying value. The Company performed its annual test for goodwill impairment as of December 31, 2016 and 2015, which did not result in any impairment charges.
