Stock Appreciation Rights (SARs)
During the year ended December 31, 2010, the Company
granted 3,795,125 (2009: 753,384) SA Rs. SA Rs can be granted
with an exercise price less than, equal to or greater than the
stock's fair market value at the date of grant and require
the Company to issue stock to the employee upon exercise of
the SA R. The SA Rs have ten year terms and vest and become
fully exercisable over varying periods between one to four
years from the date of grant.
The fair value of each SA R was estimated on the grant date
using the Black-S choles option-pricing model that used the
assumptions in the following table. The fair value is amortized
to compensation expense on a straight-line basis over the
expected term. The Company estimated the expected term of
the SA Rs using an approach that approximated the "simplified
approach." Using this approach, the Company assigned an
expected term for grants with four-year vesting. The expected
stock price volatility was determined by examining the historical
volatilities for peers and using the Company's common
stock. Industry peers consist of several public companies in
the biotechnology industry similar in size, stage of life cycle
and financial leverage. The risk-free interest rate assumption is
based on the US Treasury instruments at grant date whose
term was consistent with the expected term of the Company's
SA Rs. The expected dividend assumption is based on the
Company's history and expectation of dividend payouts.
