(1)	Determined based on expected annual dividend yield at the time of grant.
(2)	Determined based on historical volatility of the Company’s Common Shares over the expected life of the option.
(3)	Determined based on the yield on U.S. Treasury zero-coupon issues with maturity dates equal to the expected life of the option.
(4)	Determined using simplified method, as the Company changed the vesting period of its stock option grants from five years to three years in 2016, and, as a result, historical exercise data may not provide a reasonable basis upon which to estimate expected life.

Includes, but is not limited to, unvested options for which requisite service period has not been rendered but that are expected to vest based on achievement of performance condition, if forfeitures are recognized when they occur.
