Stock-Based Compensation and Shareholders' Equity

3.   Stock-Based Compensation and Shareholders’ Equity

Equity Compensation Plans

The Company grants, or has granted, stock options and other stock and stock-based awards under The 2006 Stock Incentive Plan (2006 Plan). The 2006 Plan was approved by the Company’s Board of Directors on January 23, 2006 and was approved by shareholders on March 14, 2006 and subsequently amended in March 2006, June 2009, September 2009, December 2009, December 2010 and June 2011. The 2006 Plan provides for the grant of up to 15 million shares of the Company’s common stock, plus such number of additional shares that were subject to outstanding options under the Company’s previous plans that are not issued because the applicable option award subsequently terminates or expires without being exercised. The 2006 Plan provides for the grant of incentive stock options intended to qualify under Section 422 of the Internal Revenue Code of 1986, as amended, non-statutory stock options, stock appreciation rights, restricted stock, restricted stock units and other stock-based awards. Employees, officers, directors, consultants and advisors of the Company and its subsidiaries are eligible to be granted awards under the 2006 Plan. No award may be made under the 2006 Plan after March 13, 2016, but awards previously granted may extend beyond that date. The Company will not grant further options under any previous plans.

While the Company may grant to employees options that become exercisable at different times or within different periods, the Company has generally granted to employees options that vest over five years and become exercisable in annual installments of 20% on each of the first, second, third, fourth and fifth anniversaries of the date of grant; 331/3% on each of the third, fourth, and fifth anniversaries of the date of grant; or in annual installments of 25% on each of the second, third, fourth and fifth anniversaries of the date of grant. The maximum contractual term of all options is ten years. In addition, the Company has granted to employees restricted stock units that generally vest in one installment on the third anniversary of the grant date.

As of October 29, 2011, a total of 10,803,862 common shares were available for future grant and 47,007,728 common shares were reserved for issuance under the 2006 Plan.

Grant-Date Fair Value

The Company uses the Black-Scholes option pricing model to calculate the grant-date fair value of stock option awards. The grant date fair value of restricted stock units represents 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.

Information pertaining to the Company’s stock option awards and the related estimated weighted-average assumptions to calculate the fair value of stock options granted is as follows:

							2009 Excluding
							Option
							Exchange
	2011			2010			Program			2009*
Options granted (in thousands)		1,990			1,866			5,675			20,873
Weighted-average exercise price-stock options	$	37.59		$	31.49		$	19.63		$	25.74
Weighted-average grant date fair value-stock options	$	8.62		$	7.77		$	7.42		$	5.97
Assumptions:
Weighted-average expected volatility		29.3	%		31.4	%		58.8	%		41.3	%
Weighted-average expected term (in years)		5.3			5.3			5.3			4.7
Risk-free interest rate		2.1	%		2.5	%		1.7	%		1.4	%
Expected dividend yield		2.4	%		2.6	%		4.1	%		3.2	%

* Includes options granted under the stock option exchange program which is described below.

Expected volatility — The Company is responsible for estimating volatility and has considered a number of factors, including third-party estimates, when estimating volatility. The Company currently believes that the exclusive use of implied volatility results in the best estimate of the grant-date fair value of employee stock options because it reflects the market’s current expectations of future volatility. In evaluating the appropriateness of exclusively relying on implied volatility, the Company concluded that: (1) options in the Company’s common stock are actively traded with sufficient volume on several exchanges; (2) the market prices of both the traded options and the underlying shares are measured at a similar point in time to each other and on a date close to the grant date of the employee share options; (3) the traded options have exercise prices that are both near-the-money and close to the exercise price of the employee share options; and (4) the remaining maturities of the traded options used to estimate volatility are at least one year.

Expected term — The Company uses historical employee exercise and option expiration data to estimate the expected term assumption for the Black-Scholes grant-date valuation. The Company believes that this historical data is currently the best estimate of the expected term of a new option, and that generally its employees exhibit similar exercise behavior.

Risk-free interest rate — The yield on zero-coupon U.S. Treasury securities for a period that is commensurate with the expected term assumption is used as the risk-free interest rate.

Expected dividend yield — Expected dividend yield is calculated by annualizing the cash dividend declared by the Company’s Board of Directors for the current quarter and dividing that result by the closing stock price on the date of grant. Until such time as the Company’s Board of Directors declares a cash dividend for an amount that is different from the current quarter’s cash dividend, the current dividend will be used in deriving this assumption. Cash dividends are not paid on options, restricted stock or restricted stock units.

Stock-Based Compensation Expense

The amount of stock-based compensation expense recognized during a period is based on the value of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The term “forfeitures” is distinct from “cancellations” or “expirations” and represents only the unvested portion of the surrendered stock-based award. Based on an analysis of its historical forfeitures, the Company has applied an annual forfeiture rate of 4.3% to all unvested stock-based awards as of October 29, 2011. The rate of 4.3% represents the portion that is expected to be forfeited each year over the vesting period. This analysis will be re-evaluated quarterly and the forfeiture rate will be adjusted as necessary. Ultimately, the actual expense recognized over the vesting period will only be for those options that vest.

Additional paid-in-capital (APIC) Pool

The APIC pool represents the excess tax benefits related to share-based compensation that are available to absorb future tax deficiencies. If the amount of future tax deficiencies is greater than the available APIC pool, the Company records the excess as income tax expense in its consolidated statements of income. For fiscal years 2009 and 2010, the Company had a sufficient APIC pool to cover any tax deficiencies recorded and as a result, these deficiencies did not affect its results of operations. During fiscal 2011, the Company recognized an immaterial amount of income tax expense resulting from tax shortfalls related to share-based compensation in its consolidated statement of income.

Stock-option Exchange

During fiscal 2009, shareholders approved and the Company completed an employee stock option exchange program (Option Exchange). The Option Exchange provided eligible employees of the Company, except named executive officers and directors, the opportunity to exchange eligible stock option grants for a smaller number of new stock options with a lower exercise price, or in some instances cash, that had approximately the same fair value as the options surrendered.

On September 28, 2009 the Company granted stock options for approximately 15.2 million shares in the aggregate to approximately 3,100 employees who elected to participate in the Option Exchange. The new stock options issued were subject to a new vesting period and a new contractual term based on the grant date of the original options. In addition, the Company made cash payments of approximately $2.6 million to approximately 5,100 employees whose exchanged options would each have resulted in a new stock option for fewer than 100 shares. As a result of the exchange, employees elected to surrender options for approximately 33.6 million options, which were cancelled upon the grant of the new options on September 28, 2009.

The exchange of options in this Option Exchange is treated as a modification of the existing stock options for accounting purposes. Accordingly, any unrecognized compensation expense from the surrendered stock options will be recognized over the original service period of the surrendered option. Because the exchange ratios were calculated to result in the fair value of surrendered eligible stock options that was approximately equal to the fair value of the new stock options replacing them, the amount of incremental expense was immaterial.

Stock-Based Compensation Activity

A summary of the activity under the Company’s stock option plans as of October 29, 2011 and changes during the fiscal year then ended is presented below:

						Weighted-
				Weighted-		Average
				Average		Remaining
	Options			Exercise Price		Contractual		Aggregate
	Outstanding			Per Share		Term in Years		Intrinsic Value
Options outstanding at October 30, 2010		43,079		$	29.87
Options granted		1,990		$	37.59
Options exercised		(8,260	)	$	26.32
Options forfeited		(450	)	$	27.71
Options expired		(2,243	)	$	44.08
Options outstanding October 29, 2011		34,116		$	30.27		4.5	$	274,486
Options exercisable at October 29, 2011		21,510		$	31.44		3.5	$	155,665
Options vested or expected to vest October 29, 2011(1)		33,507		$	30.29		4.4	$	269,320

(1) In addition to the vested options, the Company expects a portion of the unvested options to vest at some point in the future. Options expected to vest is calculated by applying an estimated forfeiture rate to the unvested options.

The total intrinsic value of options exercised (i.e. the difference between the market price at exercise and the price paid by the employee to exercise the options) during fiscal 2011, 2010 and 2009 was $96.5 million, $29.6 million and $4.7 million, respectively. The total amount of proceeds received by the Company from exercise of these options during fiscal 2011, 2010 and 2009 was $217.4 million, $240.4 million and $15.1 million, respectively.

Proceeds from stock option exercises pursuant to employee stock plans in the Company’s statement of cash flows of $217.2 million, $216.1 million and $12.4 million for fiscal 2011, 2010 and 2009, respectively, are net of the value of shares surrendered by employees in certain limited circumstances to satisfy the exercise price of options, and to satisfy employee tax obligations upon vesting of restricted stock or restricted stock units and in connection with the exercise of stock options granted to the Company’s employees under the Company’s equity compensation plans. The withholding amount is based on the Company’s minimum statutory withholding requirement.

A summary of the Company’s restricted stock unit award activity as of October 29, 2011 and changes during the year then ended is presented below:

	Restricted			Weighted-
	Stock			Average Grant-
	Units			Date Fair Value
	Outstanding			Per Share
Restricted stock units outstanding at October 30, 2010		1,265		$	28.21
Units granted		898		$	34.93
Restrictions lapsed		(33	)	$	24.28
Units forfeited		(42	)	$	31.39
Restricted stock units outstanding at October 29, 2011		2,088		$	31.10

As of October 29, 2011, there was $88.6 million of total unrecognized compensation cost related to unvested share-based awards comprised of stock options and restricted stock units. That cost is expected to be recognized over a weighted-average period of 1.3 years. The total grant-date fair value of shares that vested during fiscal 2011, 2010 and 2009 was approximately $49.6 million, $67.7 million and $74.4 million, respectively.

Common Stock Repurchase Program

The Company’s common stock repurchase program has been in place since August 2004. In the aggregate, the Board of Directors has authorized the Company to repurchase $5 billion of the Company’s common stock under the program. Under the program, the Company may repurchase outstanding shares of its common stock from time to time in the open market and through privately negotiated transactions. Unless terminated earlier by resolution of the Company’s Board of Directors, the repurchase program will expire when the Company has repurchased all shares authorized under the program. As of October 29, 2011, the Company had repurchased a total of approximately 125.0 million shares of its common stock for approximately $4,278.5 million under this program. An additional $721.5 million remains available for repurchase of shares under the current authorized program. The repurchased shares are held as authorized but unissued shares of common stock. Any future common stock repurchases will be dependent upon several factors, including the amount of cash available to the Company in the United States and the Company’s financial performance, outlook and liquidity. The Company also from time to time repurchases shares in settlement of employee tax withholding obligations due upon the vesting of restricted stock units, or in certain limited circumstances to satisfy the exercise price of options granted to the Company’s employees under the Company’s equity compensation plans.

Preferred Stock

The Company has 471,934 authorized shares of $1.00 par value preferred stock, none of which is issued or outstanding. The Board of Directors is authorized to fix designations, relative rights, preferences and limitations on the preferred stock at the time of issuance.
