Share-Based Payment Arrangement [Abstract] |
STOCK-BASED COMPENSATION | 10. STOCK‑BASED COMPENSATION Equity Incentive Plans In May 2012, we adopted the 2012 Equity Incentive Plan (the “2012 Plan”). The 2012 Plan provides for the grant of incentive stock options, nonstatutory stock options, RSAs, RSUs and Stock Appreciation Rights to employees, non-employee directors and consultants. As of December 31, 2024, total shares remaining available for issuance under the 2012 Plan were 1,758,450. Employee Stock Purchase Plan Under the 2004 Employee Stock Purchase Plan (the “2004 ESPP”), our employees may purchase common stock through payroll deductions at a price equal to 85% of the lower of the fair market value of the stock at the beginning of the offering period or at the end of each applicable purchase period. The 2004 ESPP provided for consecutive and overlapping offering periods of 24 months in duration, with each offering period composed of four consecutive six-month purchase periods. The purchase periods ended on either May 15 or November 15. The 2004 ESPP contributions were limited to a maximum of 15% of an employee’s eligible compensation. The maximum number of shares that an employee may purchase in any purchase period was 2,500. An employee may not purchase shares with a value greater than $25,000 in any calendar year. On April 13, 2023, the Board of Directors adopted the 2023 ESPP (the “2023 ESPP”). The 2023 ESPP, which supersedes the 2004 ESPP, was approved by the Company’s stockholders on May 22, 2023. Under the 2023 ESPP, eligible employees may purchase common stock through payroll deductions at a price equal to 85% of the lower of the fair market value of the stock at the beginning or end of each applicable purchase period. The 2023 ESPP provides for offering periods of six months, which ends on either May 15 or November 15. The 2023 ESPP contributions are limited to a maximum of 15% of an employee’s eligible compensation. The maximum number of shares that an employee may purchase in any purchase period is 2,500. An employee may not purchase shares with a value greater than $25,000 in any calendar year. A total of 2.5 million shares of our common stock was reserved and available for issuance under the 2023 ESPP. As of December 31, 2024, total shares remaining available for issuance under the 2024 ESPP were 2,467,596. Director Compensation Program Our non-employee directors receive compensation for services provided as a director. Each member of our board of directors who is not an employee receives both cash and equity compensation for services as a director, member of a committee of the board of directors, lead independent director and chairman, as applicable. In October 2017, both the cash and equity components of the compensation program were amended, effective immediately (the “October 2017 Amendments”). Each of our independent directors receives periodic automatic grants of equity awards under a program implemented under the 2012 Plan. These grants are non‑discretionary. Only our independent directors or affiliates of such directors are eligible to receive automatic grants under the 2012 Plan. Under the program, each individual who first became a non-employee director will, on the date such individual joins the board of directors, automatically be granted a one‑time grant of RSUs covering a number of shares of our common stock calculated as $125,000 ($250,000 prior to the October 2017 Amendments) divided by our common stock closing share price on the date of grant as reported on The Nasdaq Global Select Market, rounded down to the nearest whole share (the “Initial RSUs”), plus a one‑time grant of RSUs covering a number of shares of our common stock calculated as $225,000 ($250,000 prior to the October 2017 Amendments) divided by our common stock closing share price on the date of grant as reported on The Nasdaq Global Select Market, which would be pro-rated for the number of whole months remaining until the anniversary of the prior year’s stockholders’ meeting, rounded down to the nearest whole share (the “Pro Rata RSUs”). The Initial RSUs vest in two equal annual installments, while Pro Rata RSUs vest in a single installment at the sooner of the next annual stockholder meeting or the one-year grant anniversary, in each case subject to the non-employee director’s continuous service through the applicable vesting date. Annually, upon his or her re‑election to the board of directors at the Annual Meeting of Stockholders, each non-employee director is automatically granted an RSU covering a number of shares of our common stock calculated as $225,000 ($250,000 prior to the October 2017 Amendments) divided by our common stock closing share price on the date of grant as reported on The Nasdaq Global Select Market, rounded down to the nearest whole share. These RSUs will vest at the sooner of the next annual stockholder meeting or the one-year anniversary of grant, subject to the non-employee director’s continuous service through the applicable vesting date. Following the amendment to our non-employee director compensation program, both the annual RSUs and Initial RSUs described above remained unchanged with the exception that the number of shares of our common stock subject to each award has been reduced. These RSUs will vest in full upon the director’s death, the occurrence of a change in control or, with respect to awards made after the October 2017 Amendments, the director’s disability before the director’s service terminates. Director RSUs carry dividend equivalent rights to be credited with an amount equal to all cash dividends paid on the underlying shares of common stock while unvested. Dividend equivalents are subject to the same terms and conditions, including vesting, as the RSUs to which they attach and are paid in cash upon vesting.
