Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company recognized stock-based compensation expense of $1,295,000 and $1,323,000 in the first quarters of 2017 and 2016, respectively, within selling, general, and administrative (SG&A) expenses in the accompanying condensed consolidated statement of income. The Company recognizes compensation expense for all stock-based awards granted to employees and directors based on the grant date estimate of fair value for those awards. The fair value of RSUs is based on the grant date trading price of the Company's common stock, reduced by the present value of estimated dividends foregone during the requisite service period. For time-based RSUs, compensation expense is recognized ratably over the requisite service period for the entire award net of forfeitures. For performance-based RSUs, compensation expense is recognized ratably over the requisite service period for each separately-vesting portion of the award net of forfeitures and remeasured at each reporting period until the total number of RSUs to be issued is known. Unrecognized compensation expense related to stock-based compensation totaled approximately $7,823,000 at April 1, 2017, and will be recognized over a weighted average period of 2.0 years. On March 8, 2017, the Company granted to its executive officers performance-based RSUs, which represented, in aggregate, the right to receive 39,229 shares (the target RSU amount), subject to adjustment, with an aggregate grant date fair value of $2,234,000. The RSUs are subject to adjustment based on the achievement of the performance measure selected for the 2017 fiscal year, which is a specified target for adjusted EBITDA generated from continuing operations for the 2017 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 2017 fiscal year, these performance-based RSUs will be forfeited. In the first quarter of 2017, 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 2018, 2019, and 2020, provided that the executive officer is employed by the Company on the applicable vesting dates. On March 8, 2017, the Company also granted time-based RSUs representing 38,331 shares to its executive officers and employees with an aggregate grant date fair value of $2,183,000. These time-based RSUs generally vest in three equal annual installments on March 10 of 2018, 2019, and 2020, provided the employee remains employed by the Company on the applicable vesting dates. On March 8, 2017, the Company granted 12,000 RSUs in the aggregate to its non-employee directors with a grant date fair value of $696,000. The RSUs will vest ratably on the last day of each fiscal quarter of 2017.
