Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Compensatory Equity Incentive Plan and Other Equity Incentives | Share-based payment arrangements — The Omnibus Plan provides several available forms of stock compensation, including incentive stock options, non-qualified stock options and restricted stock unit (“RSU”) awards. Stock-based compensation is measured at grant date, based on the fair value of the award, and is recognized as an expense over the employee’s requisite service period. The Company estimates the fair value of each stock option as of the date of grant using the Black-Scholes-Merton pricing model. Most options granted under the Omnibus Plan vest ratably over two to four years and generally have ten-year contract lives. The volatility rate is based on four-year historical trends in common stock closing prices and the expected term was determined based primarily on historical experience of previously outstanding options. The interest rate used is the U.S. Treasury interest rate for constant maturities. The likelihood of meeting targets for option grants that are performance based are evaluated each quarter. If it is determined that meeting the targets is probable, then the compensation expense will be amortized over the remaining vesting period. The LightPath Technologies, Inc. Employee Stock Purchase Plan (“2014 ESPP”) was adopted by the Company’s board of directors on October 30, 2014 and approved by the Company’s stockholders on January 29, 2015. The 2014 ESPP permits employees to purchase Class A common stock through payroll deductions, which may not exceed 15% of an employee’s compensation, at a price not less than 85% of the market value of the Class A common stock on specified dates (June 30 and December 31). In no event can any participant purchase more than $25,000 worth of shares of Class A common stock in any calendar year and an employee cannot purchase more than 8,000 shares on any purchase date within an offering period of 12 months and 4,000 shares on any purchase date within an offering period of six months. This discount of approximately $4,900 and $1,900 for fiscal 2018 and 2017, respectively, is included in the selling, general and administrative expense in the accompanying Consolidated Statements Comprehensive Income, which represents the value of the 10% discount given to the employees purchasing stock under the 2014 ESPP. These plans are summarized below:

Grant Date Fair Values and Underlying Assumptions; Contractual Terms—The Company estimates the fair value of each stock option as of the date of grant. The Company uses the Black-Scholes-Merton pricing model. The 2014 ESPP fair value is the amount of the discount the employee obtains at the date of the purchase transaction. For stock options and RSUs granted in the years ended June 30, 2018 and 2017, the Company estimated the fair value of each stock award as of the date of grant using the following assumptions:
|  | Year Ended June 30,
|  | 2018 |  | 2017
Weighted-average expected volatility |  | 63% - 75% |  | 77% - 83%
Dividend yields |  | 0% |  | 0%
Weighted-average risk-free interest rate |  | 1.28% - 2.82% |  | 1.24% - 1.90%
Weighted-average expected term, in years |  | 7.27 |  | 7.49
The assumed forfeiture rates used in calculating the fair value of options and restricted stock unit grants with both performance and service conditions were 20% for each of the years ended June 30, 2018 and 2017. The volatility rate and expected term are based on seven-year historical trends in Class A common stock closing prices and actual forfeitures. The interest rate used is the U.S. Treasury interest rate for constant maturities.

The table above does not include shares under the Company’s 2014 ESPP, which has purchase settlement dates in the second and fourth fiscal quarters. The Company’s 2014 ESPP is not administered with a look-back option provision and, as a result, there is not a population of outstanding option grants during the employee contribution period. RSU awards vest immediately or from two to four years from the grant date. The Company issues new shares of Class A common stock upon the exercise of stock options.
