	Number of Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term	Aggregate Intrinsic Value (1)
	(in thousands)		(per share)		(in years)
Outstanding at January 1, 2013	2,668		$	37.56
Expired or forfeited	(191	)	36.31
Exercised	(269	)	25.96

(1)

The aggregate intrinsic value (the difference between the closing price of the Company’s common shares on the last trading day of the first quarter of 2013 and the exercise price, multiplied by the number of “in-the-money” options) that would have been received by the option holders had all option holders exercised their options on March 31, 2013. The amount of aggregate intrinsic value will change based on the fair market value of the Company’s common shares.


(2)	The options expected to vest are the result of applying the pre-vesting forfeiture rate assumption to total outstanding non-vested options.

- Definition

Tabular disclosure of components of a stock option or other award plan under which equity-based compensation is awarded to employees, typically comprised of the amount of unearned compensation (deferred compensation cost), compensation expense, and changes in the quantity and fair value of the shares (or other type of equity) granted, exercised, forfeited, and issued and outstanding pertaining to that plan. Disclosure may also include nature and general terms of such arrangements that existed during the period and potential effects of those arrangements on shareholders, effect of compensation cost arising from equity-based payment arrangements on the income statement, method of estimating the fair value of the goods or services received, or the fair value of the equity instruments granted, during the period, cash flow effects resulting from equity-based payment arrangements and, for registrants that accelerate vesting of out of the money share options, reasons for the decision to accelerate.
