Stock-Based Compensation
The Company’s employee equity programs are intended to attract, retain and motivate highly qualified employees. On April 29, 2004, the Company’s stockholders approved the 2004 Equity Incentive Plan, as amended and restated (the 2004 Plan). In the fourth quarter of 2017, the Company introduced the 2017 Employee Stock Purchase Plan, as amended and restated (the 2017 Plan).
Under the 2004 Plan, stock options generally vest and become exercisable over a three-year period from the date of grant and expire within seven years after the grant date. Unvested shares that are reacquired by the Company from forfeited outstanding equity awards become available for grant and may be reissued as new awards.
Under the 2004 Plan, the Company can grant (i) stock options, and (ii) RSUs, including time-based RSUs and PRSUs.
Stock Options. Under the 2004 Plan, nonstatutory and incentive stock options may be granted. The exercise price of the shares subject to each nonstatutory stock option and incentive stock option cannot be less than 100% of the fair market value of the Company’s common stock on the date of the grant. The exercise price of each option granted under the 2004 Plan must be paid in full at the time of the exercise.
Time-based RSUs. Time-based RSUs are awards that can be granted to any employee, director or consultant and that obligate the Company to issue a specific number of shares of the Company’s common stock in the future if the vesting terms and conditions are satisfied. The purchase price for the shares is $0.00 per share.
PRSUs. PRSUs can be granted to certain of the Company’s senior executives. The performance metrics can be financial performance, non-financial performance and/or market conditions. Each PRSU award reflects a target number of shares (Target Shares) that may be issued to an award recipient before adjusting based on the Company’s financial performance, non-financial performance and/or market conditions. The actual number of shares that a grant recipient receives at the end of the period may range from 0% to 250% of the Target Shares granted, depending upon the degree of achievement of the performance target designated by each individual award.
ESPP. Under the 2017 Plan, eligible employees who participate in an offering period may have up to 10% of their eligible earnings withheld, up to certain limitations, to purchase shares of common stock at 85% of the lower of the fair market value on the first or the last business day of the six-month offering period. The offering periods commence in May and November each year.
As of December 26, 2020, the Company had 57 million shares of common stock that were available for future grants and 22 million shares reserved for issuance upon the exercise of outstanding stock options or the vesting of unvested RSUs, including PRSUs, under the 2004 Plan. In addition, the Company had 40 million shares of common stock that were available for issuance under the 2017 plan.

Stock Options. The weighted-average estimated fair value of employee stock options granted for the years ended December 26, 2020, December 28, 2019 and December 29, 2018 was $38.49, $13.31 and $7.62 per share, respectively, using the following assumptions:
2020 2019 2018
Expected volatility 57.87  %
52.60% - 56.51%
51.51% - 60.46%
Risk-free interest rate 0.18  %

Expected dividends —  % —  % —  %
Expected life (in years) 4.3
3.94 - 3.95
3.92 - 3.94
The Company uses a combination of the historical volatility of its common stock and the implied volatility for publicly traded options on the Company’s common stock as the expected volatility assumption. The risk-free interest rate is
based on the rate for a U.S. Treasury zero-coupon yield curve with a term that approximates the expected life of the option grant at the date closest to the option grant date. The expected dividend yield is zero as the Company does not expect to pay dividends in the near future. The expected term of employee stock options represents the weighted-average period the stock options are expected to remain outstanding.
