Note 8 – Stock Based Compensation

There have been no significant changes to our equity incentive plans, Employee Stock Purchase Plan, or accounting methodology for stock based compensation, as disclosed in our 2022 Form 10-K.

The fair value of stock options and Restricted Stock Units (“RSUs”) issued to employees and directors is recognized as compensation expense over the period of service that generally coincides with the vesting period of the award. The Company allocated compensation ratably across Operating Expenses within the following financial statement lines. When calculating the amount of annual compensation expense, the Company has elected not to estimate forfeitures and instead accounts for forfeitures as they occur.

For the three months ended March 31, 2023, the Company recognized compensation costs totaling:
