Goodwill and Intangible Assets Disclosure [Abstract]

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill is tested annually, or more often than annually if circumstances warrant, for impairment. If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated, and goodwill is written down to its implied fair value. Subsequent increases in goodwill value are not recognized in the financial statements. Goodwill totaled $1.1 billion at December 31, 2019 and $845.7 million at December 31, 2018.

During 2019, the Company recorded $131.3 million and $78.5 million of goodwill as a result of its acquisitions of Landrum and Reliance, respectively. Goodwill impairment was neither indicated nor recorded in 2019, 2018 or 2017.

Core deposit premiums represent the value of the relationships that acquired banks had with their deposit customers and are amortized over periods ranging from 10 to 15 years and are periodically evaluated, at least annually, as to the recoverability of their carrying value. Other intangible assets represent the value of other acquired relationships, including relationships with trust and wealth management customers, and are being amortized over various periods ranging from 10 to 15 years.

Changes in the carrying amount and accumulated amortization of the Company’s core deposit premiums and other intangible assets at December 31, 2019 and 2018 were as follows:
