The fair value of each stock option grant under the 2013 Plan is estimated on the date of grant using the Black-Scholes-Merton option valuation model. The expected term of options granted is derived from historical data on employee exercise and post-vesting employment termination behavior. The risk-free rate is based upon the estimated life of the option and the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on the historical volatility on the Company’s stock. There were no stock options granted during the three and six months ended December 31, 2022 and 2021. There were no stock options exercised during the three and six months ended December 31, 2022. Stock Awards Stock awards may be granted under the 2013 Plan on terms approved by the Compensation Committee of the Board. Stock awards generally provide for the issuance of restricted stock units (“RSUs”) including performance-condition or market-condition RSUs which vest over a fixed period of time or based upon the satisfaction of certain performance criteria or market conditions. The Company recognizes compensation expense on the awards over the vesting period based on the awards’ fair value as of the date of grant. The Company does not estimate forfeitures, but accounts for them as incurred. The following table summarizes stock award activity for the six months ended December 31, 2022 (in thousands, except grant date fair value):
|  | Number of Shares |  |  | Weighted- Average Grant Date Fair Value |  |  | Aggregate Fair Value |
Non-vested stock awards outstanding at June 30, 2022 |  |  | 6,429 |  |  | $ | 9.57 |  |  |  |  |
Granted |  |  | 6,186 |  |  |  | 14.50 |  |  |  |  |
Released |  |  | (2,731 | ) |  |  | 8.30 |  |  |  |  |

Non-vested stock awards outstanding at December 31, 2022 |  |  | 9,643 |  |  | $ | 13.05 |  |  | $ | 176,564 |
Stock awards expected to vest at December 31, 2022 |  |  | 9,643 |  |  | $ | 13.05 |  |  | $ | 176,564 |
The RSUs granted under the 2013 Plan vest over a period of time, generally one to three years, and are subject to participant's continued service to the Company. The stock awards granted during the six months ended December 31, 2022 included 1.4 million RSUs including the market condition awards discussed below to named executive officers and directors. Market Condition Awards During the six months ended December 31, 2022 and 2021, the Compensation Committee of the Board granted 1.0 million and 0.7 million RSUs, respectively, with vesting based on market conditions (“MSU”) to certain of the Company’s executive officers. These MSUs vest based on the Company’s total shareholder return (“TSR”) relative to the TSR of the Russell 2000 Index (“Index”). The MSU award represents the right to receive a target number of shares of common stock of up to 150% of the original grant, as indicated in the table below. The MSUs vest based on the Company’s TSR relative to the TSR of the Index over performance periods of three years from the grant date, subject to the grantees’ continued service through the certification of performance.
Level | Relative TSR | Shares Vested |
Below Threshold | TSR is less than the Index by more than 37.5 percentage points | 0% |
Threshold | TSR is less than the Index by 37.5 percentage points | 25% |
Target | TSR equals the Index | 100% |
Maximum | TSR is greater than the Index by 25 percentage points or more | 150% |
Total shareholder return is calculated based on the average closing price for the 30-trading days prior to the beginning and end of the performance periods. Performance is measured based on three periods, with the ability for up to one-third of target shares to vest after years one and two and the ability for up to the maximum of the full award to vest based on the full three-year TSR less any shares vested based on one- and two-year periods. Linear interpolation is used to determine the number of shares vested for achievement between target levels. The grant date fair value of each MSU was determined using the Monte Carlo simulation model. The weighted-average grant-date fair value of the MSUs granted during the six months ended December 31, 2022 was $16.57 per share. The assumptions used in the Monte Carlo simulation included the expected volatility of 67%, risk-free rate of 3.12%, no expected dividend yield, expected term of three years and possible future stock prices over the performance period based on the historical stock and market prices. The Company recognizes the expense related to these MSUs on a graded-vesting method over the estimated term. The weighted-average grant-date fair value of the MSUs granted during the six months ended December 31, 2021 was $12.69 per share. The assumptions used in the Monte Carlo simulation included the expected volatility of 66%, risk-free rate of 0.44%, no expected dividend yield, expected term of three years and possible future stock prices over the performance period based on the historical stock and market prices. Employee Stock Purchase Plan The fair value of each share purchase option under the ESPP is estimated on the date of grant using the Black-Scholes-Merton option valuation model with the weighted average assumptions noted in the following table. The expected term of the ESPP represents the term of the offering period of each option. The risk-free rate is based upon the estimated life and on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on the historical volatility on the Company’s common stock. There were 0.7 million and 1.0 million shares issued under the ESPP during the six months ended December 31, 2022 and 2021, respectively. The following assumptions were used to determine the grant-date fair values of the ESPP shares during the following periods:
|  | Employee Stock Purchase Plan |
|  | Three Months Ended |
|  | December 31, 2022 |  |  | December 31, 2021 |
Expected life |  | 0.5 years |  |  | 0.5 years |
Risk-free interest rate |  |  | 3.12 | % |  |  | 0.05 | %
Volatility |  |  | 60 | % |  |  | 52 | %
Dividend yield |  |  | — | % |  |  | — | %
The weighted-average grant-date fair value of shares under the ESPP during the six months ended December 31, 2022 and 2021 was $4.38 and $3.18 per share, respectively.
