Stock Incentive Plans	Note 11. Stock Incentive Plans 2011 Equity Incentive plan. In November 2011, our shareholders approved the 2011 Equity Incentive Plan (the “2011 Plan”) for the purpose of affording an incentive to eligible persons. The 2011 Equity Incentive Plan provides for the grant of equity based awards, including stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalents, unrestricted stock, other equity based or equity related awards, and/or performance compensation awards based on or relating to the Company's common shares to eligible non-employee directors, officers, employees or consultants. The 2011 Plan is administered by a compensation committee or such other committee of the Company's board of directors. An aggregate of 5.9 million of the Company's common shares have been authorized for issuance under the 2011 Plan. The shares reserved for issuance under the 2011 Plan are not subject to adjustment in the event of a stock split commenced prior to the Company's 2012 Annual General Meeting. However, the 2011 Plan was approved by shareholders subject to the Company's confirmation in the proxy materials relating to the approval of the 2011 Plan that no options granted under the plan would, in the aggregate, exceed 10% of the Company's issued and outstanding shares on a fully diluted basis on the date the options first become exercisable and that the vesting of any options awarded under the 2011 Plan would be conditional on the Company refinancing or restructuring its credit facility. 2009 Equity Incentive plan. In May 2009, our shareholders approved the 2009 Equity Incentive Plan (2009 Plan) for the purpose of affording an incentive to eligible persons. The 2009 Equity Incentive Plan provides for the grant of equity based awards, including stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalents, unrestricted stock, other equity based or equity related awards, and/or performance compensation awards based on or relating to the Company's common shares to eligible non-employee directors, officers, employees or consultants. The 2009 Plan is administered by a compensation committee or such other committee of the Company's board of directors. An aggregate of 4.2 million of the Company's common shares have been authorized for issuance under the 2009 Plan. The Company permits the employees to use vested shares to satisfy the grantee's U.S. federal income tax liability resulting from issuance of the shares through the Company's retention of that number of common shares having a market value as of the vesting date equal to such tax obligation up to the minimum statutory withholding requirements. The amounts related to shares used for such tax withholding obligations were $1,680,649, $736,443 and $1,109,587 for the years ended December 31, 2011, 2010 and 2009, respectively. On March 17, 2006, the Company granted options to purchase 56,666 shares of the Company's common stock to its independent non-employee directors. These options vested and became exercisable on the grant date at an exercise price of $13.23 per share. During 2007, options to purchase 13,333 shares were exercised. The options expire ten years from the date of grant. On January 12, 2007, the Company granted options to purchase 13,334 of the Company's common shares to its independent non-employee directors and 524,000 of the Company's common shares to members of its management.

All options expire ten years from the date of grant. During 2008, options to purchase 13,333 shares were exercised and 26,667 options were forfeited. On May 23, 2007, the Company granted options to purchase 50,001 of the Company's common shares to its independent non-employee directors.

For purposes of determining the non-cash compensation cost for the Company's stock option plans using the fair value method of ASC 718 “Compensation-Stock Compensation”, the fair value of the options granted of $852,328 was estimated on the date of grant using the Black-Scholes option pricing model.
