[1] Related to RSUs and DSUs awarded to certain employees and non-employee directors.

[2] No amount was recorded for the 2012 Management Incentive Compensation Program (the “2012 MIC”), as the performance targets were not met at December 31, 2012. In 2013 and 2014, the Management Incentive Program was converted to pay out entirely in cash. Therefore, no stock-based compensation was recorded.

[3] This amount relates to options awarded on August 15, 2012 to the CEO.
