The Company adopted, and the stockholders approved, the 2017 Long-Term Incentive Plan (the “2017 Plan”), effective February 16, 2017, to provide incentives to eligible employees, directors and consultants.    The initial share pool approved was 650,000 shares.

As of March 31, 2023, a maximum of 4.0 million shares of the Company's common stock can be issued under the 2017 Plan in connection with the grant of awards which is calculated as the sum of (i) 3,492,000 shares and (ii) up to 475,000 shares previously reserved for issuance under the 2010 Plan, including shares returned upon cancellation, termination or forfeiture of awards that were previously granted under that plan. Outstanding stock options awarded under the 2017 Plan have exercise prices of $4.44 per share, and vest over a three year vesting period. Awards expire in accordance with the terms of each award and, upon expiration of the award, the shares subject to the award are added back to the 2017 Plan. The contractual term of stock options granted is generally ten years. As of March 31, 2023, under the 2017 Plan, there were stock option awards outstanding, net of awards expired, for an aggregate of 0.1 million shares of the Company's common stock.
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 March 31, 2023, 0.1 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 March 31, 2023 and 2022, approximately 40,000 and 41,000 shares of common stock were issued under the ESPP, respectively. During the nine months ended March 31, 2023 and 2022, approximately 76,000 and 68,000 shares of common stock were issued under the ESPP, respectively.
Stock-Based CompensationFor the three months ended March 31, 2023, compensation of $0.8 million was reflected as an increase to additional paid-in capital, all of which was employee related. For the three months ended March 31, 2022, a decrease to additional paid-in capital of $38,000, all of which was employee related, was recognized due to changes in estimates in performance stock unit performance measures and reductions in headcount. For the nine months ended March 31, 2023 and 2022, compensation of $2.2 million and $1.4 million, respectively, was reflected as an increase to additional paid-in capital, all of which was employee related.
