Note 10—Income Taxes

The Company uses an estimated annual effective tax rate method in computing its interim tax provision. This effective tax rate is based on forecasted annual pre-tax income, permanent tax differences and statutory tax rates.

The effective tax rate for the three months ended March 31, 2022 and 2021 was 22.0% and 25.3%, respectively. The decrease in the effective tax rate during the first quarter of 2022 was a result of income tax benefits related to share-based compensation. The Company recorded discrete income tax benefit of $1.1 million and $28,000 related to the exercise of stock options and vesting of restricted shares for the three months ended March 31, 2022 and 2021, respectively.

Net deferred tax assets increased to $67.3 million at March 31, 2022 compared to $50.3 million at December 31, 2021 primarily as a result of unrealized losses on available-for-sale securities.
