Goodwill and other intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized but tested for impairment at least annually or more frequently if events and circumstances exist that indicate that a goodwill impairment test should be performed. Intangible assets with definite useful lives are amortized over their estimated useful lives, which range from 5 to 12 years. Goodwill is the only intangible asset with an indefinite life on the consolidated balance sheets.

As a result of the Bay Banks Merger, a core deposit intangible asset of $6.9 million was recorded as of the acquisition date and is being amortized on an accelerated basis over 10 years using the sum-of-years digits method.

Included in other amortizable intangibles were loan servicing assets of $274 thousand and $209 thousand at June 30, 2021 and December 31, 2020, respectively, related to the sale of the government guaranteed portion of certain loans that the Company continues to service. Loan servicing assets of $115 thousand and $189 thousand were added during the six months ended June 30, 2021 and the year ended December 31, 2020, respectively. The amortization of these intangibles is included in interest and fees on loans in the consolidated statement of income.

The Company retains servicing rights on mortgages originated and sold to the secondary market. The Company records mortgage servicing rights (“MSR”) assets initially at fair value and subsequently accounts for them under the amortization method, pursuant to which an impairment assessment is performed each reporting period. The amortization method requires that the MSR assets be recorded at the lower of cost or fair value. As of June 30, 2021 and December 31, 2020, the carrying value of MSR assets were $13.1 million and $7.1 million, respectively.
