Stock-Based Compensation	Stock-Based Compensation Long-Term Incentive Plans The Company adopted and the shareholders 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 $1.47 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 shareholders 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 1.1 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 will be added to the 2017 Plan pool as described below. The Company adopted a performance incentive plan effective July 1, 2015 (the "Fiscal 2016 Performance Plan"). The Fiscal 2016 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 2016 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 2016 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 separate performance incentive plans effective July 1, 2016 (the "Fiscal 2017 Performance Plan") and July 1, 2017 (the "Fiscal 2018 Performance Plan"). The Fiscal 2017 Performance Plan and Fiscal 2018 Performance Plan include performance-based and service-based vesting requirements and payment terms that are substantially the same as described above the Fiscal 2016 Performance Plan. The Company adopted and the shareholders approved the 2017 Long-Term Incentive Plan (the “2017 Plan”), effective February 16, 2017, to provide incentives to eligible employees, directors and consultants. The maximum number of shares that can be issued under the 2017 Plan is not to exceed 1,125,000 shares, calculated as the sum of (i) 650,000 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, 2017, a maximum of 1.0 million shares of the Company's common stock can be issued under the 2017 Plan in connection with the grant of awards. Awards expire in accordance with the terms of each award and the shares subject to the award are added back to the 2017 Plan upon expiration of the award. 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, 2017, stock-based compensation of $0.4 million was reflected as an increase to additional paid-in capital and an increase of $0.2 million was included in other accrued expenses, all of which was employee related. For the three months ended September 30, 2016, stock-based compensation of $0.7 million was reflected as an increase to additional paid-in capital and an increase of $0.2 million was included in other accrued expenses, all of which was employee related. On January 4, 2016, the Company awarded performance restricted stock units under the 2010 Long-Term Incentive Plan to its executive officers (the "Recipients") and, in March 2016, the Company and each Recipient entered into an amended and restated stock unit agreement (the "Restated Stock Unit Agreement") amending the terms of the January 2016 awards. Under the Restated Stock Unit Agreements, vesting for the performance restricted stock units occurs at the end of a three-year performance period beginning January 1, 2016 (the "Performance Period") and is subject to achievement of both service-based and market-based performance vesting requirements. Subject generally to the Recipient's continued service with the Company (the service-based requirement) and limitations otherwise set forth in the 2010 Long-Term Incentive Plan, each performance restricted stock unit represents a contingent right for the Recipient to receive, within thirty days after the end of the performance period, a distribution of shares of common stock of the Company equal to 0% to 200% of the target number of performance restricted stock units subject to the award. The actual number of shares distributed will be based on the Company's total stockholder return ("TSR") performance during the Performance Period, subject to acceleration upon a change in control of the Company. The vesting for 50% of the performance restricted stock units is based upon the Company's absolute TSR for the performance period compared to a matrix of fixed numeric values and the vesting for the other 50% of the performance restricted stock units is based upon the relative comparison of the Company's TSR to the Vanguard Russell 2000 exchange traded fund TSR. The fair value of the performance restricted stock units will be recognized on a straight-line basis over the requisite service period of the awards, regardless of when, if ever, the market-based performance conditions are satisfied. On March 28, 2017, the Company awarded new performance restricted stock units under the 2017 Long-Term Incentive Plan to its executive officers. These awards have a three-year performance period beginning on January 1, 2017 and otherwise include the same performance-based and service-based vesting requirements as the previous awards.
