Employee Equity Incentive Plans (Tables) [Abstract]

Restricted Stock Units Estimated Values And Weighted Average Assumptions [Table Text Block]

We estimate the fair value of restricted stock unit awards with time-based vesting using the value of our common stock on the date of grant, reduced by the present value of dividends expected to be paid on our common stock prior to vesting. We estimate the fair value of market-based restricted stock units using a Monte Carlo simulation model on the date of grant. We based the weighted average estimated values of restricted stock unit grants, as well as the weighted average assumptions that we used in calculating the fair value, on estimates at the date of grant, as follows:

	Three Months Ended						Nine Months Ended
	Oct. 1,			Sept. 25,			Oct. 1,			Sept. 25,
	2011			2010			2011			2010
Estimated values	$	21.37		$	20.58		$	19.80		$	22.64
Risk-free interest rate		0.5	%		0.6	%		0.7	%		1.1	%
Dividend yield		3.6	%		2.9	%		3.4	%		2.6	%
Volatility		26	%		33	%		27	%		31	%

Stock Options And Stock Purchase Plan Estimated Values And Weighted Average Assumptions [Table Text Block]

We use the Black-Scholes option pricing model to estimate the fair value of options granted under our equity incentive plans and rights to acquire stock granted under our stock purchase plan. We based the weighted average estimated values of employee stock option grants and rights granted under the stock purchase plan, as well as the weighted average assumptions used in calculating these values, on estimates at the date of grant, as follows:

	Stock Options												Stock Purchase Plan
	Three Months Ended						Nine Months Ended						Three Months Ended						Nine Months Ended
	Oct. 1,			Sept. 25,			Oct. 1,			Sept. 25,			Oct. 1,			Sept. 25,			Oct. 1,			Sept. 25,

Estimated values	$	3.82		$	5.13		$	3.88		$	4.84		$	4.90		$	4.82		$	4.69		$	4.71
Expected life (in years)		5.4			4.8			5.3			4.9			0.5			0.5			0.5			0.5
