Goodwill and Intangible Assets Disclosure [Abstract]

The Company recorded $232.2 million of provisional goodwill in connection with the Cascade merger. In accordance with the Intangibles - Goodwill and Other topic of the Financial Accounting Standards Board (“FASB”) ASC 350, goodwill is not amortized but is reviewed for potential impairment at the reporting unit level. Management analyzes its goodwill for impairment on an annual basis and between annual tests in certain circumstances, such as upon material adverse changes in legal, business, regulatory and economic factors. An impairment loss is recorded to the extent that the carrying amount of goodwill exceeds its implied fair value. The Company performed an impairment assessment as of July 1, 2017 and 2016 and concluded that there was no impairment to goodwill.

Core deposit intangibles (“CDI”) are evaluated for impairment if events and circumstances indicate a possible impairment. The CDI are amortized using an accelerated method based on the estimated weighted average useful lives of the related deposits, which is ten years. The following table sets forth activity for CDI for the three and nine months ended September 30, 2017 and 2016:

Total CDI, net, at September 30	$	50,971		$	10,546		$	50,971		$	10,546

Subsequent to the acquisition of Cascade, the Company sold the custodial rights to the all of its Health Savings Account (HSA) portfolio, including HSA acquired from Cascade. The Company recognized no gain or loss on the sale of the acquired HSA as the excess of consideration received over HSA book value was recorded as reduction to CDI at the acquisition of Cascade.

The following table provides the estimated future CDI amortization expense:
