As of December 31, 2021, the Company had two shareholder approved stock plans under which shares were available for equity-based awards; the Callaway Golf Company Amended and Restated 2004 Incentive Plan (the "2004 Incentive Plan") and the 2013 Non-Employee Directors Stock Incentive Plan (the "2013 Directors Plan"). The Company also had one non-shareholder approved stock plan, the 2021 Employment Inducement Plan (the "2021 Inducement Plan"), which was adopted in connection with the Company's merger with Topgolf on March 8, 2021. The 2021 Inducement Plan has substantially the same terms as the Company's 2004 Incentive Plan, with the exception that awards can only be made to new employees in connection with their commencement of employment and incentive stock options cannot be granted under the 2021 Inducement Plan. In general, the Company grants stock options, restricted stock units, performance based awards, phantom stock units and other awards under these plans.

The 2004 Incentive Plan permits the granting of stock options, stock appreciation rights, restricted stock awards, restricted stock units, performance share units and other equity-based awards to the Company’s officers, employees, consultants and certain other non-employees who provide services to the Company. All grants under the 2004 Incentive Plan are discretionary, although no participant may receive awards in any one year in excess of 2,000,000 shares. The maximum number of shares issuable over the term of the 2004 Incentive Plan is 33,000,000.

The 2013 Directors Plan permits the granting of stock options, restricted stock awards and restricted stock units to eligible directors serving on the Company's Board of Directors. Directors may receive a one-time grant upon their initial appointment to the Board and thereafter an annual grant upon being re-elected at each annual meeting of shareholders, not to exceed 50,000 shares within any calendar year. The maximum number of shares issuable over the term of the 2013 Directors Plan is 1,000,000.

The 2021 Inducement Plan was adopted in connection with the Company's merger with Topgolf on March 8, 2021. The plan permits the granting of stock options, stock appreciation rights, restricted stock awards, restricted stock units, performance share units and other equity-based awards to the Company’s officers, employees, consultants and certain other non-employees who provide services to the Company. The maximum number of shares issuable over the term of the 2021 Inducement Plan is 1,300,000.

In connection with the merger with Topgolf which was completed on March 8, 2021, the Company converted certain stock options previously held by former equity holders of Topgolf into options to purchase a number of shares of Callaway common stock, and certain outstanding restricted stock awards of Topgolf into shares of Callaway common stock (together, the "replacement awards"). The Company also assumed two equity compensation plans and a stock option agreement between Topgolf and a third party in connection with the merger (collectively, the "Topgolf Equity

Compensation Plans and Option Agreement"). No additional awards may be granted by the Company under the assumed Topgolf Equity Plans and Option Agreement. Additionally, the Company included $33,051,000 in the consideration transferred for the replacement awards issued connection with the merger, which represents the fair value of the vested portion of the replacement awards. As of the year ended December 31, 2021, the unvested portion of the replacement awards, which is associated with the future services that will be rendered in the post-combination period, is comprised of 3,168,000 shares underlying stock options with an acquisition date fair value of $5,343,000, and 188,000 shares of restricted stock awards with an acquisition date fair value of $4,794,000. All activity related to share-based awards for the year December 31, 2021, includes the Replacement Awards issued in connection with the merger with Topgolf (see Note 6).

The fair value of the stock options granted in connection with the merger was based on the Black-Scholes option-pricing model. The model uses various assumptions including an expected term, stock price volatility, risk-free interest rate, and dividend yield. Assumptions related to the expected term and stock price volatility were based on historical exercise patterns and historical fluctuations in volatility relative to the Company's stock price, respectively. Assumptions related to the risk-free interest rate and dividend yield were based on the yield-curve of a zero-coupon U.S. treasury bond on the date the grants were made with a maturity equal to the expected term of the grant, and an assumed dividend yield based on the Company's expectation to not pay dividends for the foreseeable future, respectively. The table below summarizes the range and the weighted averages of the fair value assumptions used in the Black-Scholes valuation as of March 8, 2021.

For the years ended December 31, 2021, 2020 and 2019, the weighted average grant-date fair value of restricted stock units granted was $29.60, $17.84 and $15.63, respectively.
