5. GOODWILL AND INTANGIBLE ASSETS

The Company’s intangible assets consist of core deposits, goodwill, and other intangibles arising from previous acquisitions. The Company has determined that its core deposit intangibles have finite lives and they are amortized over their estimated useful lives, which ranges from four years to ten years, using an accelerated method. Other amortizable intangible assets are being amortized over the period of expected benefit, which ranges from four years to ten years, using various methods. The Company concluded that there was no impairment to goodwill or intangible assets as of the balance sheet date. In the normal course of business, the Company routinely monitors the impact of the changes in the financial markets and includes these assessments in the Company’s impairment process.

As a result of the American National acquisition, the Company recorded goodwill totaling $288.8 million at March 31, 2025. See Note 2 “Acquisitions” in Part I, Item I of this Quarterly Report for more information on the American National acquisition.
