Options vested and expected to vest at September 30, 2014 (2)	1,601		37.31		6	2,914

(1) The aggregate intrinsic value (the difference between the closing price of the Company’s common shares on the last trading day of the third quarter of 2014 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 September 30, 2014. 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.
