The Company’s stock-based incentive 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 (the 2004 Plan). The Company introduced the Employee Stock Purchase Plan (ESPP) in the fourth quarter of 2017.
Under the 2004 Plan, stock options generally vest and become exercisable over a three-year period from the date of grant and expire within ten 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 Performance-based Restricted Stock Units (PRSUs).
Stock Options. A stock option is the right to purchase shares of the Company’s common stock at a fixed exercise price for a fixed period of time. 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.
Performance-based Restricted Stock Units. Performance-based Restricted Stock Units (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.
Employee Stock Purchase Plan. Under the ESPP, eligible employees who participate in an offering period may have up to 10% of their 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 28, 2019, the Company had 61 million shares of common stock that were available for future grants and 30 million shares reserved for issuance upon the exercise of outstanding stock options or the vesting of unvested restricted stock units. In addition, the Company had 42 million shares of common stock that were available for issuance under the ESPP.

During 2019, 2018 and 2017, the Company did not realize any excess tax benefits related to stock-based compensation and therefore the Company did not record any related financing cash flows.
Stock Options. The weighted-average estimated fair value of employee stock options granted for the years ended December 28, 2019, December 29, 2018 and December 30, 2017 was $13.31, $7.62 and $5.46 per share, respectively, using the following assumptions:

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 required by the lattice-binomial model. 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 and is a derived output of the lattice-binomial model.
