STOCK-BASED COMPENSATION

February 21, 2014,

the Compensation Committee of our Board of Directors approved, subject to stockholder approval, a

third

amendment (the "Third Amendment") to the

2006

Omnibus Incentive Plan (the "Incentive Plan"). The Third Amendment (i) provides that the maximum aggregate number of shares of Class A common stock available for grant of awards under the Incentive Plan from and after

May 29, 2014,

shall

not

exceed

750,000,

plus any remaining available shares of the

800,000

shares previously made available under the

second

amendment to the Incentive Plan (the "Second Amendment"), and any expirations, forfeitures, cancellations, or certain other terminations of shares approved for grant under the Third Amendment or the Second Amendment previously reserved, plus any remaining expirations, forfeitures, cancellations, or certain other terminations of such shares, and (ii) re-sets the term of the Incentive Plan to expire with respect to the ability to grant new awards on

March 31, 2023.

The Compensation Committee also re-approved, subject to stockholder re-approval, the material terms of the performance-based goals under the Incentive Plan so that certain incentive awards granted thereunder would continue to qualify as exempt "performance-based compensation" under Internal Revenue Code Section

162

(m). The Company's stockholders approved the adoption of the Third Amendment and re-approved the material terms of the performance-based goals under the Incentive Plan at the Company's

2014

Annual Meeting held on

May 29, 2014.

The

Incentive Plan permits annual awards of shares of our Class A common stock to executives, other key employees, non-employee directors, and eligible participants under various types of options, restricted share awards, or other equity instruments. At

December 31, 2017,

186,430

of the

1,550,000

shares noted above were available for award under the amended Incentive Plan.

participant in the Incentive Plan

may

receive awards of any type of equity instruments in any calendar-year that relates to more than

200,000

shares of our Class A common stock.

awards

may

be made under the Incentive Plan after

March 31, 2023.

To the extent available, we have issued treasury stock to satisfy all share-based incentive plans.

Included in salaries, wages, and related expenses within the consolidated statements of operations

is stock-based compensation expense of

$1.0

million,

$1.2

million, and

$1.3

million in

2017,

2016,

and

2015,

respectively. Included in general supplies and expenses within the consolidated statements of operations is stock-based compensation expenses for non-employee directors of

$0.3

million in

2017,

and

$0.2

million in

2016

and

2015,

respectively. All stock compensation expense recorded in

2017,

2016,

and

2015

relates to restricted shares granted, as

options were granted during these periods. Associated with stock compensation expense was

$0.5

million,

$1.1

million, and

income tax benefit in

2017,

2016,

and

2015,

respectively, related to the exercise of stock options and restricted share vesting.

The Incentive Plan allows participants to pay the federal and state minimum statutory tax withholding requirements related to awards that vest or allows the participant to deliver to us shares of Class A common stock having a fair market value equal to the minimum amount of such required withholding taxes. To satisfy withholding requirements for shares that vested, certain participants elected to deliver to us

31,297,

55,429,

and

84,138

Class A common stock shares, which were withheld at weighted average per share prices of

$25.09,

$20.61,

and

$27.10

based on the closing prices of our Class A common stock on the dates the shares vested in

2017,

2016,

and

2015,

respectively, in lieu of the federal and state minimum statutory tax withholding requirements. We remitted

$0.8,

$1.1

million, and

$2.3

million in

2017,

2016,

and

2015,

respectively, to the proper taxing authorities in satisfaction of the employees' minimum statutory withholding requirements. The payment of minimum tax withholdings on stock compensation are reflected within the issuances of restricted shares from treasury stock in the accompanying consolidated statement of stockholders' equity.

2018

The fair value of restricted

and

2015

was approximately

$2.4

million,

$3.5

million, and

we had approximately

All restricted shares awarded to executives and other key employees pursuant to the Incentive Plan provide the holder with voting and other stockholder-type rights, but will

not

be issued until the relevant restrictions are satisfied.
