4. Share-based incentive plans — Stock Option Awards. We have established the Tuesday Morning Corporation 2008 Long-Term Equity Incentive Plan (the “2008 Plan”) and the Tuesday Morning Corporation 2014 Long-Term Incentive Plan, as amended (the “2014 Plan”), which allow for the granting of stock options to directors, officers and key employees of the Company, and certain other key individuals who perform services for us and our subsidiaries. Equity awards may no longer be granted under the 2008 Plan, but equity awards granted under the 2008 Plan are still outstanding.

Stock options were awarded under the 2008 Plan and the 2014 Plan with a strike price at the fair market value equal to the closing price of our common stock on the date of the grant.

Options granted under the 2008 Plan and the 2014 Plan typically vest over periods of one to four years and expire ten years from the date of grant. Options granted under the 2008 Plan and the 2014 Plan may have certain performance requirements in addition to service terms. If the performance conditions are not satisfied, the options are forfeited. The exercise prices of stock options outstanding on September 30, 2020 range between $1.64 per share and $20.91 per share. The 2008 Plan terminated as to new awards as of September 16, 2014. There were 3.5 million shares available for grant under the 2014 Plan at September 30, 2020.

Restricted Stock Awards—The 2008 Plan and the 2014 Plan authorize the grant of restricted stock awards to directors, officers, key employees and certain other key individuals who perform services for us and our subsidiaries. Equity awards may no longer be granted under the 2008 Plan, but restricted stock awards granted under the 2008 Plan are still outstanding. Restricted stock awards are not transferable, but bear certain rights of common stock ownership including voting and dividend rights. The 2014 Plan also authorizes the issuance of restricted stock units which, upon vesting, provide for the issuance of an equivalent number of shares of common stock or a cash payment based on the value of our common stock at vesting. Restricted units are not transferable and do not provide voting or dividend rights. Shares and units are valued at the fair market value of our common stock on the date of the grant. Shares and units may be subject to certain performance requirements. If the performance requirements are not met, the restricted shares or units are forfeited. Under the 2008 Plan and the 2014 Plan, as of September 30, 2020, there were 1,177,396 shares of restricted stock and 1,094,785 restricted stock units outstanding with award vesting periods, both performance-based and service-based, of one to four years and a weighted average grant date fair value of $2.28 and $1.90 per share, respectively.

Performance-Based Restricted Stock Awards and Performance-Based Stock Option Awards. As of September 30, 2020, there were 287,348 unvested performance-based restricted stock awards and performance-based restricted stock units payable in cash outstanding under the 2014 Plan.
