Future Estimated Amortization Expense for CDI

Goodwill and Other Intangible Assets: Goodwill is determined as the excess of the fair value of the consideration transferred, plus the fair value of any noncontrolling interests in the acquiree, over the fair value of the net assets acquired and liabilities assumed as of the acquisition date. Goodwill that arises from a business combination is periodically evaluated for impairment at the reporting unit level, at least annually. Intangible assets with definite useful lives are amortized over their estimated useful lives to their estimated residual values. Core deposit intangible ("CDI") represents the estimated future benefit of deposits related to an acquisition and is booked separately from the related deposits and evaluated periodically for impairment. The CDI asset is amortized on a straight-line method over its estimated useful life of ten years. At December 31, 2020, the future estimated amortization expense for the CDI arising from our past acquisitions is as follows:

(in thousands)	2021		2022		2023		2024		2025		Thereafter		Total
Core Deposit Intangible Amortization	$	611	$	593	$	573	$	549	$	522	$	1,165	$	4,013
