Performance Based Restricted Stock Units [Abstract]
Performance-based Restricted Stock Units, Terms of Award	On March 5, 2014, the Company granted to executive officers of the Company performance-based restricted stock units (RSUs), which represented, in aggregate, the right to receive 56,445 shares (the target RSU amount), subject to adjustment, with a grant date fair value of $38.81 per share. The RSUs are subject to adjustment based on the achievement of the performance measure selected for the 2014 fiscal year, which is a specified target for adjusted EBITDA generated from continuing operations for the 2014 fiscal year. The RSUs are adjusted by comparing the actual adjusted EBITDA for the performance period to the target adjusted EBITDA. Actual adjusted EBITDA between 50% and 100% of the target adjusted EBITDA results in an adjustment of 50% to 100% of the RSU amount. Actual adjusted EBITDA between 100% and 115% of the target adjusted EBITDA results in an adjustment using a straight-line linear scale between 100% and 150% of the RSU amount. If actual adjusted EBITDA is below 50% of the target adjusted EBITDA for the 2014 fiscal year, all performance-based RSUs will be forfeited. In the first quarter of 2014, the Company recognized compensation expense based on the probable number of performance-based RSUs expected to vest, which was 100% of the target RSU amount. Following the adjustment, the performance-based RSUs will be subject to additional time-based vesting, and will vest in three equal annual installments on March 10 of 2015, 2016, and 2017, provided that the executive officer is employed by the Company on the applicable vesting dates.
