STOCK-BASED COMPENSATION

At June 29, 2019, the Company had one stock incentive plan, the Company's 1996 Stock Incentive Plan (the “1996 Plan”) and one employee stock purchase plan, the 2008 Employee Stock Purchase Plan (the “2008 ESPP”). The 1996 Plan was adopted by the Board of Directors to provide the grant of incentive stock options, non-statutory stock options, restricted stock units (“RSUs”), and market stock units (“MSUs”) to employees, directors, and consultants.

Pursuant to the 1996 Plan, the exercise price for incentive stock options and non-statutory stock options is determined to be the fair market value of the underlying shares on the date of grant. Options typically vest ratably over a four-year period measured from the date of grant. Options generally expire no later than seven years after the date of grant, subject to earlier termination upon an optionee's cessation of employment or service.

RSUs granted to employees typically vest ratably over a four-year period and are converted into shares of the Company's common stock upon vesting, subject to the employee's continued service to the Company over that period. RSUs granted after August 2017 will continue to vest post-employment at the Company for certain individuals satisfying specific eligibility requirements.

MSUs granted to employees typically vest over a four-year period and are converted into shares of the Company's common stock upon vesting, subject to the employee's continued service to the Company over that period. The number of shares that are released at the end of the performance period can range from zero to a maximum cap depending on the Company's performance. For MSUs granted prior to September 2017, the performance metrics of this program are based on relative performance of the Company’s stock price as compared to the Semiconductor Exchange Traded Fund index SPDR S&P (the “XSD”). For MSUs granted after August 2017, the performance metrics for this program are based on the total shareholder return ("TSR") of the Company relative to the TSR of the other companies included in the XSD. These MSUs vest based upon annual performance subject to continued service through the end of the four-year cliff period. MSUs granted after August 2017 will continue to vest post-employment at the Company for certain individuals satisfying specific eligibility requirements.

The fair value of options granted to employees under the 1996 Plan is estimated on the date of grant using the Black-Scholes option valuation model.

The Company did not grant any stock options in fiscal years 2019, 2018 or 2017.

The following table summarizes outstanding, exercisable and vested and expected to vest stock options as of June 29, 2019 and their activity during fiscal years 2019, 2018 and 2017:

(1)	Aggregate intrinsic value represents the difference between the exercise price and the closing price per share of the Company's common stock on June 28, 2019, the last business day preceding the fiscal year end, multiplied by the number of options outstanding, exercisable or vested and expected to vest as of June 29, 2019.

The total intrinsic value of options exercised during fiscal years 2019, 2018 and 2017 were $27.5 million, $30.7 million and $55.1 million, respectively.

Restricted Stock Units and Other Awards

The fair value of RSUs and other awards under the Company’s 1996 Plan is estimated using the value of the Company’s common stock on the date of grant, reduced by the present value of dividends expected to be paid on the Company’s common stock prior to vesting. The Company also estimates forfeitures at the time of grant and makes revisions to forfeitures on a quarterly basis.

The weighted average fair value of RSUs and other awards granted was $53.97, $44.95 and $37.33 per share for fiscal years 2019, 2018 and 2017, respectively.

The following table summarizes outstanding and expected to vest RSUs and other awards as of June 29, 2019 and their activity during fiscal years 2019, 2018 and 2017:
