FIS employees participate in an Employee Stock Purchase Plan ("ESPP"). Eligible employees may voluntarily purchase, at current market prices, shares of FIS' common stock through payroll deductions. Pursuant to the ESPP, employees may contribute an amount between 3% and 15% of their base salary and certain commissions. Shares purchased are allocated to employees based upon their contributions. The Company contributes a matching amount as specified in the ESPP of 25% of the employee's contribution. The Company recorded expense of $20 million, $15 million, and $14 million, respectively, for the years ended December 31, 2020, 2019 and 2018, relating to the participation of FIS employees in the ESPP.

The Company's U.S. employees are covered by a qualified 401(k) plan. Eligible employees may contribute up to 40% of their eligible compensation, up to the annual amount allowed pursuant to the Internal Revenue Code. The Company generally matches 50% of each dollar of employee contribution up to 6% of the employee's total eligible compensation. The Company recorded expense of $107 million, $91 million and $82 million, respectively, for the years ended December 31, 2020, 2019 and 2018, relating to the participation of FIS employees in the 401(k) plan.

In 2008, the Company adopted the FIS 2008 Omnibus Incentive Plan ("FIS Plan"). In May 2013, the FIS Plan was combined with a plan assumed in conjunction with the 2009 Metavante acquisition ("FIS Restated Plan"). The restatement authorized an additional 6 million shares for issuances, which was approved by stockholders in 2013. In May 2015, another 12 million shares were authorized for issuance under the FIS Restated Plan and approved by stockholders.

On November 30, 2015, in conjunction with the SunGard acquisition, the Company registered an additional 10 million shares, representing the remaining shares available for issuance under the SunGard 2005 Management Incentive Plan ("the SG Plan"), as amended immediately prior to the consummation of the SunGard acquisition. These shares are available for grant under the FIS Restated Plan for legacy SunGard employees and FIS employees hired after the SunGard acquisition.

On July 31, 2019, in conjunction with the Worldpay acquisition, the Company registered an additional 24 million shares, representing the remaining shares available for issuance under the Worldpay Inc. 2012 Equity Incentive Plan ("Worldpay Plan"), as amended immediately prior to the consummation of the Worldpay acquisition. These shares are available for grant under the FIS Restated Plan for legacy Worldpay employees and FIS employees hired after the Worldpay acquisition.

Also on July 31, 2019, in conjunction with the Worldpay acquisition, the Company registered up to 7 million shares of FIS common stock on a Post-Effective Amendment on Form S-8, reserved for issuance with respect to converted outstanding awards issued under the Worldpay Plan to individuals employed by Worldpay at the effective time of the merger.

During 2019, in conjunction with the Worldpay acquisition, the Company converted outstanding Worldpay equity awards into corresponding FIS equity awards, pursuant to the terms of the merger agreement. The converted equity awards are subject to time-based vesting criteria and include change in control provisions allowing for acceleration of unvested awards in the event of termination of employment without cause or for good reason.

Stock options granted under the FIS Restated Plan for the years ended December 31, 2020, 2019 and 2018 are subject to time-based vesting criteria. Restricted stock units granted under the FIS Restated Plan for the years ended December 31, 2020 and 2019, are subject to time-based vesting criteria as well as performance and/or market conditions for certain grants. The grants with performance and market conditions are subject to the achievement of certain financial performance measures. Participants have the right to earn 0% to 300% of the target number of shares of the Company's common stock, determined by the level of the financial performance measures achieved during the performance period. The restricted stock units granted under the FIS Restated Plan for the year ended December 31, 2018, are subject to time-based vesting criteria as well as market conditions for certain grants.

The Company grants stock options to certain key employees, which typically vest annually over three years. All stock options are non-qualified stock options, the stock options granted by the Company expire on the seventh anniversary of the grant date, and the stock options converted through the Worldpay acquisition expire on the tenth anniversary of the grant date.

The intrinsic value of options exercised during the years ended December 31, 2020, 2019 and 2018 was $348 million, $189 million and $257 million, respectively. The intrinsic value of the outstanding options and options exercisable is based on a closing stock price as of December 31, 2020 of $141.46. The Company issues authorized but unissued shares or shares from treasury stock to settle stock options exercised.

The number of options granted for the years ended December 31, 2020, 2019 and 2018 was 2 million, 1 million and 1 million, respectively. The weighted average exercise price was $120.47, $113.48 and $96.49 for the years ended December 31, 2020, 2019 and 2018, respectively.

The weighted average fair value of options granted during the years ended December 31, 2020, 2019 and 2018, was $21.17, $19.25 and $16.07, respectively, using the Black-Scholes option pricing model with the assumptions below:

The options converted through the Worldpay acquisition on July 31, 2019, had a weighted average fair value of $71.05, a weighted average risk free interest rate of 1.9%, a weighted volatility of 18.6%, a weighted average dividend yield of 1.0% and a weighted average expected life of 3.9 years.

The Company estimates future forfeitures at the time of grant and revises those estimates in subsequent periods if actual forfeitures differ significantly from those estimates. The Company bases the risk-free interest rate that is used in the Black-Scholes model on U.S. Treasury securities issued with maturities similar to the expected term of the options. The expected stock volatility factor is determined using historical daily price of the common stock and the impact of any expected trends. The dividend yield assumption is based on the current dividend yield at the grant date or management's forecasted expectations. The expected life assumption is determined by calculating the average term from the Company's historical stock option activity and considering the impact of future trends.

The Company issues restricted stock units, which typically vest annually over three years. The grant date fair value of the restricted stock units is based on the fair market value of our common stock on the grant date. The number of restricted stock units granted during the years ended December 31, 2020, 2019 and 2018 was 1 million, 2 million and 1 million, respectively. The weighted average grant date fair value of these awards granted during the years ended December 31, 2020, 2019 and 2018, was $127.14, $124.72 and $96.50, respectively. Certain restricted stock units granted in 2020 and 2019 are also subject to performance-based vesting criteria. Certain of the restricted stock units granted in 2020, 2019 and 2018 are also subject to market conditions. The total fair value of restricted stock units that vested was $293 million, $169 million and $97 million in 2020, 2019 and 2018, respectively.

The Company recorded total stock compensation expense of $283 million, $402 million and $84 million for the years ended December 31, 2020, 2019 and 2018, respectively, included in Selling, general, and administrative expenses in the consolidated statements of earnings. Stock compensation expense recorded related to the grants with performance conditions is based on management's expected level of achievement of the financial performance measures during the performance period and is adjusted as appropriate throughout the performance period based on the shares expected to be earned at that time.
