Cash-Settled Plans 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 for the Fiscal 2016 Performance Plan. Employee Stock Purchase Plan The Employee Stock Purchase Plan ("ESPP") was adopted on September 20, 2018, and subsequently approved by the shareholders on November 15, 2019. The purpose of the ESPP is to provide the Company's employees with the ability to acquire shares of the Company's common stock at a discount to the purchase date fair market value through payroll deductions. During the three and six months ended December 31, 2018, no payroll deductions were made and no shares of common stock were purchased under the ESPP. The first six-month offering period will begin in March 2019. 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 and six months ended December 31, 2018, stock-based compensation of $1.0 million and $1.6 million, respectively, was reflected as an increase to additional paid-in capital and an increase of $0.7 million and $1.4 million, respectively, was included in other accrued expenses, all of which was employee related.
