Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and Other Intangible Assets | Goodwill and Other Intangible Assets (a) Goodwill The Company’s goodwill represents the excess of the purchase price over the fair value of net assets acquired in the following mergers: Premier Commercial Bancorp and Puget Sound Bancorp in 2018; Washington Banking Company in 2014; Valley Community Bancshares in 2013; Western Washington Bancorp in 2006 and North Pacific Bank in 1998. The Company’s goodwill is assigned to the Bank and is evaluated for impairment at the Bank level (reporting unit). There were no additions to goodwill during the three months ended March 31, 2021 and 2020. Management analyzes its goodwill on an annual basis on December 31 and between annual tests in certain circumstances such as 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 annual impairment assessment as of December 31, 2020 and concluded that there was no impairment. (b) Other Intangible Assets Other intangible assets represent core deposit intangibles acquired in business combinations. The useful life of the core deposit intangibles was estimated to be ten years for the acquisitions of Premier Commercial Bancorp, Puget Sound Bancorp, Washington Banking Company, and Valley Community Bancshares. The following table presents the change in other intangible assets for the periods indicated:
