Employee Stock Purchase Plan General. The Company's 2019 Employee Stock Purchase Plan ("ESPP") was adopted by the board of directors in September 2018 and the Company's stockholders approved it in November 2018. The ESPP is intended to qualify under Section 423 of the Internal Revenue Code. Share Reserve. The Company has reserved 0.4 million shares of its common stock for issuance under the ESPP. As of September 30, 2022, 0.2 million shares were available for issuance. The number of shares reserved under the ESPP will automatically be adjusted in the event of a stock split, stock dividend or a reverse stock split (including an adjustment to the per-purchase period share limit). Purchase Price. Employees may purchase each share of common stock under the ESPP at a price equal to 85% of the lower of the fair market values of the stock as of the beginning or the end of the six-month offering periods. An employee's contributions to the ESPP are limited to 15% of their regular hourly or salary compensation, and up to a maximum of 3,000 shares may be purchased during any offering period. A participant shall not be granted an option under the ESPP if such option would permit the participant's rights to purchase stock to accrue at a rate exceeding $25,000 grant date fair market value of stock for each calendar year in which such option is outstanding at any time. Offering Periods. Unless otherwise determined by the compensation committee, the ESPP will be operated through a series of successive six-month offering periods, which will begin each year on March 1 and September 1. During the three months ended September 30, 2022 and 2021, approximately 36,000 and 27,000 shares of common stock were issued under the ESPP, respectively. Stock-Based Compensation In accordance with accounting guidance for stock-based compensation, payments in equity instruments for goods or services are accounted for by the fair value method. For the three months ended September 30, 2022 and 2021, compensation of $0.6 million and $0.6 million, respectively. was reflected as an increase to additional paid-in capital, all of which was employee related.
