Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

The Company has certain stock-based compensation plans under which it grants stock-based awards, including common stock, stock options, time-based restricted share units (“RSUs”), and performance-based restricted share units (“Performance RSUs”) to attract, retain, and reward talented employees, officers, and directors, and to align stockholder and employee interests.

Compensation expense for stock-based awards is based on fair value at the measurement date. This expense fluctuates over time as a function of the duration of vesting periods of the stock-based awards and the Company’s performance, as measured by criteria set forth in performance-based awards. Stock-based compensation expense is included in general and administrative expenses in the condensed consolidated statements of operations and the amount of expense ultimately recognized depends on the quantity of awards that actually vest. Accordingly, stock-based compensation expense may vary from period to period.

The performance criteria for the Company’s performance-based equity awards utilize the Company’s operating earnings (adjusted for certain amounts) as a percentage of contract revenues for the applicable four-quarter period (a “Performance Year”) and its Performance Year operating cash flow level (adjusted for certain amounts). Additionally, certain awards include three-year performance measures that, if met, result in supplemental shares awarded. For Performance RSUs, the Company evaluates compensation expense quarterly and recognizes expense for performance-based awards only if it determines it is probable that performance criteria for the awards will be met.

Stock-based compensation expense and the related tax benefit recognized during the three and nine months ended October 26, 2019 and October 27, 2018 were as follows (dollars in thousands):



	For the Three Months Ended				For the Nine Months Ended
	October 26, 2019		October 27, 2018		October 26, 2019		October 27, 2018
Stock-based compensation	$	2,694	$	7,366	$	8,450	$	18,277
Income tax effect of stock-based compensation	$	669	$	2,083	$	2,098	$	4,572

In addition, during the three months ended October 26, 2019 and October 27, 2018, the Company realized approximately $0.2 million of net tax deficiencies and approximately $0.1 million of net excess tax benefits, respectively, related to the vesting

and exercise of share-based awards. During the nine months ended October 26, 2019 and October 27, 2018, the Company realized approximately $0.8 million of net tax deficiencies and $0.7 million of net excess tax benefits, respectively.

As of October 26, 2019, the Company had unrecognized compensation expense related to stock options, RSUs, and target Performance RSUs (based on the Company’s expected achievement of performance measures) of $2.3 million, $10.1 million, and $10.6 million, respectively. This expense will be recognized over a weighted-average number of years of 2.3, 2.5, and 1.8, respectively, based on the average remaining service periods for the awards. As of October 26, 2019, the Company may recognize an additional $27.9 million in compensation expense in future periods if the maximum number of Performance RSUs is earned based on certain performance measures being met.
