Share-based Payment Arrangement [Abstract] |
Stock-Based Compensation | Stock-Based Compensation Long-Term Incentive Plans Equity-Settled Plans The Company adopted, and the stockholders approved, the 2007 Long-Term Incentive Plan (the “2007 Plan”), effective November 21, 2006, to provide incentives to eligible employees, directors and consultants. A maximum of 1.4 million shares of the Company's common stock can be issued under the 2007 Plan in connection with the grant of awards. Awards to purchase common stock have been granted pursuant to the 2007 Plan and are outstanding to various employees, officers, directors, Scientific Advisory Board members and independent distributors at prices between $1.75 and $10.50 per share, with initial vesting periods of one to three years. Awards expire in accordance with the terms of each award and the shares subject to the award are added back to the 2007 Plan upon expiration of the award. The contractual term of stock options granted is generally ten years. Effective November 21, 2016, no new awards can be granted under the 2007 Plan. The Company adopted, and the stockholders approved, the 2010 Long-Term Incentive Plan (the “2010 Plan”), effective September 27, 2010, as amended on August 21, 2014, to provide incentives to certain employees, directors and consultants. A maximum of 1.0 million shares of the Company's common stock can be issued under the 2010 Plan in connection with the grant of awards. Awards to purchase common stock have been granted pursuant to the 2010 Plan and are outstanding to various employees, officers and directors. Outstanding stock options awarded under the 2010 Plan have exercise prices between $5.60 and $20.09 per share, and vest over one to four year vesting periods. Awards expire in accordance with the terms of each award and, upon expiration of the award, the shares subject to the award will be added to the 2017 Plan pool as described below. The contractual term of stock options granted is generally ten years. No new awards will be granted under the 2010 Plan and forfeited or terminated shares may be added to the 2017 Plan pool as described below. 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. On February 2, 2018 and November 15, 2018, the stockholders approved amendments to the 2017 Plan to increase by 425,000 shares and 715,000 shares, respectively, the number of shares of the Company's common stock that are available for issuance under the 2017 Plan. The maximum number of shares that can be issued under the 2017 Plan is not to exceed 2,265,000 shares, calculated as the sum of (i) 1,790,000 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. As of September 30, 2019, a maximum of 2.3 million shares of the Company's common stock can be issued under the 2017 Plan in connection with the grant of awards. 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 are substantially the same as described above for the 2007 Plan and 2010 Plan. As of September 30, 2019, there were stock option awards outstanding, net of awards expired, for an aggregate of 0.4 million shares of the Company's common stock. Cash-Settled Plans The Company adopted a performance incentive plan effective July 1, 2016 (the "Fiscal 2017 Performance Plan"). The Fiscal 2017 Performance Plan is intended to provide selected employees an opportunity to earn performance-based cash bonuses whose value is based upon the Company’s stock value and to encourage such employees to provide services to the Company and to attract new individuals with outstanding qualifications. The Fiscal 2017 Performance Plan seeks to achieve this purpose by providing for awards in the form of performance share units (the “Units”). No shares will be issued under the Fiscal 2017 Performance Plan. Awards may be settled only with cash and will be paid subsequent to award vesting. The fair value of share-based compensation awards, that include performance shares, are accounted for as liabilities. Vesting for the Units is subject to achievement of both service-based and performance-based vesting requirements. Performance-based vesting occurs in three installments if the Company meets certain performance criteria generally set for each year of a three-year performance period. The service-based vesting criteria occurs in a single installment at the end of the third fiscal year after the awards are granted if the participant has continuously remained in service from the date of award through the end of the third fiscal year. The fair value of these awards is based on the trading price of the Company's common stock and is remeasured at each reporting period date until settlement. The Company adopted a separate performance incentive plan effective July 1, 2017 (the "Fiscal 2018 Performance Plan"). The Fiscal 2018 Performance Plan includes performance-based and service-based vesting requirements and payment terms that are substantially the same as described above for the Fiscal 2017 Performance Plan. 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 its 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 400,000 shares of its common stock for issuance under the ESPP. As of September 30, 2019, 367,114 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, 2019, 32,886 shares of common stock were issued under the ESPP. During the three months ended September 30, 2018, no shares of common stock were issued. 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, 2019, stock-based compensation of $1.3 million was reflected as an increase to additional paid-in capital and an increase of $41,000 was included in other accrued expenses, all of which was employee related. For the three months ended September 30, 2018, stock-based compensation of $0.6 million was reflected as an increase to additional paid-in capital and an increase of $0.7 million was included in other accrued expenses, all of which was employee related.
