Stockholders' Equity, Reverse Stock Split	Effective as of the opening of trading on May 22, 2012, the Company completed a 1 for 4 reverse stock split as previously approved by the Company's shareholders. Proportional adjustments were made to the Company's issued and outstanding common stock and to its common stock underlying stock options and other common stock-based equity grants outstanding immediately prior to the effectiveness of the reverse stock split to reflect the reverse stock split. No fractional shares were issued in connection with the reverse stock split, as shareholders who would otherwise hold a fractional share of common stock received a cash payment in lieu of that fractional share. All references herein to common stock and per share data have been retrospectively adjusted to reflect the reverse stock split.

Share-based Compensation Arrangement by Share-based Payment Award, Description		In May 2009, our shareholders approved the 2009 Equity Incentive Plan (the "2009 Plan") for the purpose of affording an incentive to eligible persons. The 2009 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. A maximum of 1.05 million of the Company's common shares have been authorized for issuance under the 2009 Plan, which have been adjusted in accordance with the one-for-four reverse stock split effective on May 22, 2012.	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.
