Secondary Public Offering
On February 8, 2021, the Company closed a secondary public offering of 15,109,489 shares of its common stock for gross proceeds of $103.5 million. The Company received net proceeds of $96.8 million after deducting underwriters' discounts and other offering related expenses.
Amended and Restated 2012 Long-Term Incentive Plan
The Company has a stockholder-approved 2012 Long-Term Incentive Plan (the “Plan”) that was amended and restated in fiscal year 2022 which added an additional 5.9 million shares. The Plan has 9.0 million shares authorized for issuance of new shares, with 4.8 million performance shares and restricted shares outstanding, and 4.2 million shares available for future issuance under the Plan as of March 31, 2022.
Stock options under the Plan are granted at prices determined by the Board of Directors, but at not less than the fair market value of the Company's common stock on the date of grant. The majority of performance share units, restricted stock units and stock options granted to employees vest over three years. Stock options, performance shares and restricted stock grants to non-employee directors typically vest over one year. The term of each stock option under the Plan will not exceed seven years. Stock options, performance share units and restricted stock units granted under the Plan are subject to forfeiture if employment terminates.

2021 Inducement Plan

The Company's 2021 Inducement Plan became effective on February 1, 2021 and provides for issuance of inducement equity awards to individuals who were not previously an employee or non-employee director of the Company as an inducement material to such individual's entering into employment with the Company. The term of each stock option and restricted stock unit under the plan will not exceed seven years, and each award generally vests between two and four years. There were no shares available for future issuance as of March 31, 2022.
The Company accounts for all forfeitures of stock-based awards when they occur.
Employee Stock Purchase Plan
The Company's has an Employee Stock Purchase Plan (the "ESPP") which enables eligible employees to purchase shares of its common stock at a discount. Purchases will be accomplished through participation in discrete offering periods. On each purchase date, eligible employees will purchase the Company's common stock at a price per share equal to 85% of the lesser of (i) the fair market value of the Company's common stock on the first trading day of the offering period, and (ii) the fair market value of the Company's common stock on the purchase date.
The Company has reserved shares of common stock for future issuance under its ESPP as follows (in thousands):

The Company uses the Black-Scholes-Merton option-pricing model (“Black-Scholes”) to determine the fair value for stock options, shares forecasted to be issued pursuant to its ESPP, and warrants. This requires the use of assumptions about expected life, stock price, volatility, risk-free interest rates and expected dividends.

Expected Life—The expected term was based on historical experience with similar awards, giving consideration to the contractual terms, exercise patterns and post-vesting forfeitures.

Volatility—The expected stock price volatility for the Company's common stock was based on the historical volatility of its common stock over the most recent period corresponding with the estimated expected life of the award.

Risk-Free Rate—The risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected term of the options for each option group.

Dividend Yield—The Company has never declared or paid any cash dividends and do not currently plan to pay cash dividends in the foreseeable future. Consequently, an expected dividend yield of zero was used.

The weighted-average grant date fair value and the assumptions used in calculating fair values of shares forecasted to be issued pursuant to the Company's ESPP are as follows:

Performance Stock Units
The Company granted 0.6 million, 0.9 million, and 1.5 million of performance share units with market conditions (“Market PSUs”) in fiscal 2022, 2021, and 2020, respectively. Market PSUs vest one to three years from the issuance date and become eligible for vesting based on the Company achieving certain stock price targets and are contingent upon continued service of the holder of the award during the vesting period. The estimated fair value of these Market PSUs is determined at the issuance date using a Monte Carlo simulation model.

Assumptions used in the Monte Carlo model to calculate fair values of market PSU’s during each fiscal period are as follows:
Weighted-Average 2022 2021 2020
Discount period (years) 2.98 2.54 3.00
Risk-free interest rate 0.93% 0.31% 1.45%
Stock price volatility 75.00% 82.00% 72.00%
Grant date fair value $5.40 $3.77 $5.92

The Company granted 0.0 million, 0.5 million and 0.3 million of performance share units with financial performance conditions (“Performance PSUs”) in the fiscal years ended March 31, 2022, 2021 and 2020, respectively. Performance PSUs become eligible for vesting based on the Company achieving certain financial performance targets through the end of the fiscal year when the performance PSUs were granted, and are contingent upon continued service of the holder of the award during the vesting period. Performance PSUs are valued at the market closing share price on the date of grant and compensation expense for Performance PSUs is recognized when it is probable that the performance conditions will be achieved. Compensation expense recognized related to Performance PSUs is reversed if the Company determines that it is no longer probable that the performance conditions will be achieved.
The following table summarizes activity for Market PSUs and Performance PSUs for the year ended March 31, 2022 (shares in thousands):
