Stock-based compensation
Note 10 - Stock-based compensation

The fair value of share-based awards granted is estimated on the date of grant using the Black-Scholes option pricing model. The key assumptions for this model are expected term, expected volatility, risk-free interest rate, dividend yield and strike price. Many of these assumptions are judgmental and the value of share-based awards is highly sensitive to changes in these assumptions.

During the nine months ended September 30, 2011, the Company granted no stock options and 75,000 restricted stock units. There were 30,000 stock options exercised, 210,000 stock options and 91,000 restricted stock units forfeited.
