In fiscal 2009, the stockholders of the Company approved the 2009 Stock Incentive Plan (the "2009 Plan") and the 2009 Employee Stock Purchase Plan (the "2009 Purchase Plan"). The 2009 Plan is currently effective, and no further grants will be issued under the Company's 2000 Stock Incentive Plan (the "2000 Plan") as of the effective date of the 2009 Plan. The 2009 Plan has a term of 10 years from the shareholders' approval date. The 2009 Purchase Plan became effective upon the termination of the previous Employee Stock Purchase Plan (the "Purchase Plan"), on April 30, 2010. There is no provision for an automatic share reserve increase in either the 2009 Plan or the 2009 Purchase Plan.

Under the 2009 Plan, the following may be granted: stock options, stock appreciation rights, performance shares, performance stock units, restricted stock units (RSUs), restricted stock awards (RSAs), performance-based awards and other awards (collectively, all such grants are referred to as "awards"). Awards of stock options and stock appreciation rights each deduct one share from the 2009 Plan shares available for issuance for each share granted, and full value awards (awards other than for which the participant is required to pay at least the fair market value of the underlying shares on the date of grant) deduct 1.55 shares from the 2009 Plan shares available for issuance for each share granted. Awards granted under the 2009 Plan generally contain vesting provisions ranging from three to four years. The exercise price of stock options offered under the 2009 Plan may not be less than 100% of the fair market value of a share of our common stock on the date of grant. To the extent awards granted under the 2009 Plan terminate, expire or lapse for any reason, or are settled in cash, shares subject to such awards will again be available for grant.

In fiscal 2000, the Company's Board of Directors and stockholders approved the 2000 Plan. The 2000 Plan contains programs for (i) the discretionary granting of stock options to employees, non-employee board members and consultants for the purchase of shares of the Company's common stock, (ii) the discretionary issuance of common stock directly (as granted under direct issuance shares in RSAs and RSUs), (iii) the granting of special below-market stock options to executive officers and other highly compensated employees of the Company for which the exercise price can be paid using payroll deductions and (iv) the automatic issuance of stock options to non-employee board members. The discretionary issuance of common stock, RSUs and stock options generally contain vesting provisions ranging from three to eight years. If permitted by the Company, stock options can be exercised immediately and, similar to the direct issuance shares, are subject to repurchase rights which generally lapse in accordance with the vesting schedule. The repurchase rights provide that upon certain defined events, the Company can repurchase unvested shares at the price paid per share. The term of each stock option is no more than ten years from the date of grant.

The Company granted to its employees 0.8 million, 0.8 million and 0.2 million shares of full value awards and no stock options from the 2009 Plan during fiscal 2011, 2010 and 2009, respectively. The Company granted to its employees 0.8 million of full value awards from the 2000 Plan during fiscal 2009. There were no significant modifications made to any stock grants during these periods.

Included in the full value awards granted under the 2009 Plan in fiscal 2011 were a total of 55 thousand market-based stock awards. The awards, also known as Market Stock Units (MSUs), provide the rights to acquire a number of shares of common stock for no cash consideration based upon achievement of specified levels of market conditions. The requisite service period for these MSUs is also the vesting period, which is generally three years. The performance criteria of the MSUs measure the difference between the total stockholders' return of the Company against that of the Philadelphia Semiconductor Sector Total Return Index.

The rights to purchase common stock granted under the 2009 Purchase Plan are intended to be treated as either (i) purchase rights granted under an "employee stock purchase plan," as that term is defined in Section 423(b) of the Internal Revenue Code (the "423(b) Plan"), or (ii) purchase rights granted under an employee stock purchase plan that is not subject to the terms and conditions of Section 423(b) of the Internal Revenue Code (the "Non-423(b) Plan"). The Company will retain the discretion to grant purchase rights under either the 423(b) Plan or the Non-423(b) Plan. Eligible employees may purchase a limited number of shares of the Company's common stock at no less than 85% of the fair market value of a share of common stock at prescribed purchase intervals during an offering period. Each offering period will be comprised of a series of one or more successive and/or overlapping purchase intervals and has a maximum term of 24 months. During fiscal 2011 and 2010, the Company issued 169 thousand and 75 thousand shares, respectively, under the 2009 Purchase Plan to its employees. The weighted-average fair value for purchase rights granted under the 2009 Purchase Plan for fiscal 2011 was $10.98 per share.

The Purchase Plan was adopted by the Company's Board of Directors in fiscal 2000. Eligible employees could purchase a limited number of shares of the Company's common stock at 85% of the market value during a series of offering periods. Each offering period is divided into semi-annual purchase intervals and has a maximum term of 24 months. During fiscal 2011, 2010 and 2009, the Company issued zero, 79 thousand and 148 thousand shares, respectively, under the Purchase Plan to its employees. There were no purchase rights granted under the Purchase Plan for fiscal 2011.

Stock-based compensation costs are based on the fair values on the date of grant for stock options and on the date of enrollment for the employee stock purchase plans, estimated by using the Black-Scholes option-pricing model. The fair values of stock awards and RSUs equal their intrinsic value on the date of grant. The fair values of market-based performance awards generally are estimated using a Monte Carlo simulation based on the date of grant.

The Black-Scholes valuation calculation requires the Company to estimate key assumptions such as future stock price volatility, expected terms, risk-free rates and dividend yield. Expected stock price volatility is based upon a combination of both historical volatility and implied volatility derived from traded options on the Company's stock in the marketplace. Expected term is derived from an analysis of historical exercises and remaining contractual life of options. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company has never paid cash dividends and does not currently intend to pay cash dividends, thus it has assumed a 0% dividend yield.

The Monte Carlo simulation used to calculate the fair value of the MSUs simulates the present value of the potential outcomes of future stock prices of the Company and the Philadelphia Semiconductor Sector Total Return Index over the requisite service period. The projection of stock prices are based on the risk-free rate of return, the volatilities of the stock price of the Company and the Index, and the correlation of the stock price of the Company with the Index.

The Company must estimate potential forfeitures of stock grants and adjust compensation cost recorded accordingly. The estimate of forfeitures will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures are recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock-based compensation expense to be recognized in future periods.

The fair values of stock options and RSUs are amortized as compensation expense on a straight-line basis over the vesting period of the grants. The fair values of RSAs are fully expensed in the period of grant, when shares are immediately issued with no vesting restrictions. The fair values of MSUs are amortized as compensation expense on a straight-line basis over the performance period of the grants. Compensation expense recognized is shown in the operating activities section of the Consolidated Statements of Cash Flows.

The fair values estimated from the Black-Scholes option-pricing model were calculated using the following assumptions:
