Share-based Benefit Plans

2005 Incentive Plan. On May 27, 2005, the Company’s stockholders approved the 2005 Stock Incentive Plan, which was amended in May 2006 and renamed the 2005 Incentive Plan (“2005 Plan”). Shares of the Company’s common stock may be issued under the 2005 Plan pursuant to three separate equity incentive programs: (i) the discretionary grant program under which stock options and stock appreciation rights may be granted to officers and other employees, non-employee board members and independent consultants, (ii) the stock issuance program under which shares may be awarded to such individuals through restricted stock or restricted stock unit awards or as a stock bonus for services rendered to the Company, and (iii) an automatic grant program for the non-employee board members pursuant to which such individuals will receive option grants or other stock awards at designated intervals over their period of board service. The 2005 Plan also includes a performance-based cash bonus awards program for executive officers classified under Section 16 of the Securities Exchange Act of 1934, as amended. Grants and awards under the discretionary grant program generally vest as follows: 25% of the shares will vest on the first anniversary of the vesting commencement date and the remaining 75% will vest proportionately each quarter over the next 12 quarters of continued service. Awards under the stock issuance program generally vest in equal annual installments over a 4-year period. Grants under the automatic grant program vest in accordance with the specific vesting provisions set forth in that program. A total of 37,045,436 shares of the Company’s common stock has been reserved for issuance under this plan. The share reserve may increase by up to 10,000,000 shares of common stock to the extent that outstanding options under the 1995 Stock Option Plan and the 1995 Non-Employee Directors Stock Option Plan expire or terminate unexercised, of which 2,345,449 shares of common stock as of December 30, 2012 had been added to the 2005 Plan reserve. All options granted under the 2005 Plan were granted with an exercise price equal to the fair market value of the common stock on the date of grant and will expire seven years from the date of grant.

1995 Stock Option Plan and 1995 Non-Employee Directors Stock Option Plan. Both of these plans terminated on May 27, 2005, and no further option grants were made under the plans after that date. However, options that were outstanding under these plans on May 27, 2005 continue to be governed by their existing terms and may be exercised for shares of the Company’s common stock at any time prior to the expiration of the ten-year option term or any earlier termination of those options in connection with the optionee’s cessation of service with the Company.

2005 Employee Stock Purchase Plan. The 2005 Employee Stock Purchase Plan (“ESPP”) was approved by the stockholders on May 27, 2005. The ESPP consists of two components: a component for employees residing in the U.S. and an international component for employees who are non-U.S. residents. The ESPP allows eligible employees to purchase shares of the Company’s common stock at the end of each six-month offering period at a purchase price equal to 85% of the lower of the fair market value per share on the start date of the offering period or the fair market value per share on the purchase date. The ESPP has 10,000,000 shares reserved for issuance, of which 4,969,553 shares were available to be issued as of December 30, 2012. In fiscal years 2012, 2011 and 2010, a total of 684,646 shares, 613,452 shares and 966,288 shares of common stock, respectively, had been issued under this plan.

Acquired Plans. In connection with the Company’s acquisitions of FlashSoft, Pliant Technology, Inc. (“Pliant”), msystems Ltd. (“msystems”) and Matrix Semiconductor, Inc. (“Matrix”), the Company adopted various equity incentive plans, which were effective upon completion of the applicable acquisition. Each of these plans was terminated as of the date of acquisition and no further grants were made under any of these plans after their termination. However, any unvested option grants that were outstanding under these plans at the date of acquisition continue to be governed by their existing terms and may be exercised for shares of the Company’s common stock.

Accounting for Share-based Compensation Expense

For share-based awards expected to vest, compensation cost is based on the grant-date fair value. The Company recognizes compensation expense for the fair values of these awards, which have graded vesting, on a straight-line basis over the requisite service period of each of these awards, net of estimated forfeitures.

The Company estimates the fair value of stock options granted using the Black-Scholes-Merton option-pricing formula and a single-option award approach. The Company’s expected term represents the period that the Company’s share-based awards are expected to be outstanding and was determined based on historical experience regarding similar awards, giving consideration to the contractual terms of the share-based awards. The Company’s expected volatility is based on the implied volatility of its traded options. The Company has historically not paid dividends and has no foreseeable plans to issue dividends. The risk-free interest rate is based on the yield from U.S. Treasury zero-coupon bonds with an equivalent term.

At December 30, 2012, the total compensation cost related to stock options granted to employees under the Company’s share-based compensation plans but not yet recognized was approximately $87.1 million, net of estimated forfeitures. This cost will be amortized on a straight-line basis over a weighted average period of approximately 2.4 years. As of December 30, 2012, the Company had fully expensed all of its SARs awards.

Restricted Stock Units. Restricted stock units (“RSUs”) are settled in shares of the Company’s common stock upon vesting on a one-for-one basis. Typically, vesting of RSUs is subject to the employee’s continuing service to the Company. The cost of these awards is determined using the fair value of the Company’s common stock on the date of grant, and compensation is recognized on a straight-line basis over the requisite vesting period.

A summary of the changes in RSUs outstanding under the Company’s share-based compensation plan during the three fiscal years ended December 30, 2012 is presented below (in thousands, except for weighted average grant date fair value):
