Stock Incentive Plans [Abstract]

Stock Incentive Plans

14. Stock Incentive Plans

Our Amended and Restated 2005 Long-Term Incentive Plan authorizes up to 6,200,000 shares of common stock to be issued at the discretion of the Compensation Committee of the Board of Directors. The 2005 Plan replaced the 1995 Stock Incentive Plan and the Stock Plan for Non-Employee Directors. The options granted to officers and key employees under the 1995 Plan continued to vest through 2010 and expire ten years from the date of grant. Our non-employee directors, officers and key employees are eligible to participate in the 2005 Plan. The 2005 Plan allows for the issuance of, among other things, stock options, restricted stock, deferred stock units and dividend equivalent rights. Vesting periods for options, deferred stock units and restricted shares generally range from three years for non-employee directors to five years for officers and key employees. Options expire ten years from the date of grant.

Option Award Activity

The following table summarizes information about stock option activity for the nine months ended September 30, 2011:

Stock Options	Number of Shares (000’s)			Weighted Average Exercise Price		Weighted Average Remaining Contract Life (years)		Aggregate Intrinsic Value ($000’s)
Options at beginning of year		1,207		$	39.45		8.0
Options granted		289			49.17
Options exercised		(153	)		37.43
Options terminated		(7	)		43.02
Options at end of period		1,336		$	41.77		7.8	$	14,255
Options exercisable at end of period		506		$	38.90		6.2	$	6,842
Weighted average fair value of options granted during the period				$	9.60

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying options and the quoted price of our common stock for the options that were in-the-money at September 30, 2011. During the nine months ended September 30, 2011 and 2010, the aggregate intrinsic value of options exercised under our stock incentive plans was $2,190,000 and $668,000, respectively (determined as of the date of option exercise). Cash received from option exercises under our stock incentive plans was $5,740,000 for the nine months ended September 30, 2011.

As of September 30, 2011, there was approximately $4,551,000 of total unrecognized compensation cost related to unvested stock options granted under our stock incentive plans. That cost is expected to be recognized over a weighted average period of four years. As of September 30, 2011, there was approximately $14,676,000 of total unrecognized compensation cost related to unvested restricted stock granted under our stock incentive plans. That cost is expected to be recognized over a weighted average period of three years.
