Stock-Based Compensation

On February 8, 2012, the Company awarded 310,500 annual service-based stock options under the Company's 2009 Long-Term Incentive Plan (the “2009 LTIP”) that vest 20% annually over five years, with 155,250 of the options being subject to shareholder approval of the proposed amendment to the 2009 LTIP (which amendment increases the number of common shares available for issuance under the 2009 LTIP by 900,000). The stock options were granted at an exercise price of $12.23, which represents the closing price of the Company's common shares on the date of grant. The grant date fair value of the stock options ($5.85) was determined at the date of grant using the Black-Scholes option pricing model.

Total recorded compensation expense relating to equity awards granted under the 2009 LTIP was approximately $0.4 million for the three months ended March 31, 2012, which includes compensation cost recognized on the basis of the proportion of service rendered over the period of February 8, 2012 through March 31, 2012 of the conditional stock options discussed above.
