Equity Compensation

The Werner Enterprises, Inc. Amended and Restated Equity Plan (the "Equity Plan"), approved by the Company's shareholders, provides for grants to employees and non-employee directors of the Company in the form of nonqualified stock options, restricted stock and units ("restricted awards"), performance stock and units ("performance awards"), and stock appreciation rights. The Board of Directors or the Compensation Committee of our Board of Directors determines the terms of each award, including the type, recipients, number of shares subject to and vesting conditions of each award. No awards of stock appreciation rights have been issued under the Equity Plan to date. The maximum number of shares of common stock that may be awarded under the Equity Plan is 20,000,000 shares. The maximum aggregate number of shares that may be awarded to any one person in any one calendar year under the Equity Plan is 500,000. As of March 31, 2015, there were 7,160,434 shares available for granting additional awards.

Equity compensation expense is included in salaries, wages and benefits within the Consolidated Statements of Income. As of March 31, 2015, the total unrecognized compensation cost related to non-vested equity compensation awards was approximately $14.5 million and is expected to be recognized over a weighted average period of 2.6 years.

The following table summarizes the equity compensation expense and related income tax benefit recognized in the Consolidated Statements of Income (in thousands):

We do not have a formal policy for issuing shares upon an exercise of stock options or vesting of restricted and performance awards. Such shares are generally issued from treasury stock. From time to time, we repurchase shares of our common stock, the timing and amount of which depends on market and other factors. Historically, the shares acquired from such repurchases have provided us with sufficient quantities of stock to issue for equity compensation. Based on current treasury stock levels, we do not expect to repurchase additional shares specifically for equity compensation during 2015.

Stock Options

Stock options are granted at prices equal to the market value of the common stock on the date the option award is granted. Option awards currently outstanding become exercisable in installments from 24 to 72 months after the date of grant. The options are exercisable over a period not to exceed ten years, one day from the date of grant.

The following table summarizes stock option activity for the three months ended March 31, 2015:



	Number of Options (in thousands)		Weighted Average Exercise Price ($)		Weighted Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value (in thousands)
Outstanding at beginning of period	248		$	18.18
Granted	—		—
Exercised	(40	)	17.47
Forfeited	—		—
Expired	—		—
Outstanding at end of period	208		18.32		3.74	$	2,726
Exercisable at end of period	161		17.77		3.25	$	2,194

We did not grant any stock options during the three-month periods ended March 31, 2015 and March 31, 2014. The fair value of stock option grants is estimated using a Black-Scholes valuation model. The total intrinsic value of stock options exercised was $0.6 million and $1.4 million for the three-month periods ended March 31, 2015 and March 31, 2014, respectively.

Restricted Awards

Restricted stock entitles the holder to shares of common stock when the award vests. Restricted stock units entitle the holder to a combination of cash or stock equal to the value of common stock when the unit vests. The value of these shares may fluctuate according to market conditions and other factors. Restricted awards currently outstanding vest over periods ranging from 12 to 84 months from the grant date of the award. The restricted awards do not confer any voting or dividend rights to recipients until such shares vest and do not have any post-vesting sales restrictions.

The following table summarizes restricted award activity for the three months ended March 31, 2015:



	Number of Restricted Awards (in thousands)	Weighted Average Grant Date Fair Value ($)
Nonvested at beginning of period	643	$	22.92
Granted	—	—
Vested	—	—
Forfeited	—	—
Nonvested at end of period	643	22.92

We did not grant any restricted awards during the three-month periods ended March 31, 2015 and March 31, 2014. We estimate the fair value of restricted awards based upon the market price of the underlying common stock on the date of grant, reduced by the present value of estimated future dividends because the awards are not entitled to receive dividends prior to vesting. Our estimate of future dividends is based on the most recent quarterly dividend rate at the time of grant, adjusted for any known future changes in the dividend rate. Cash settled restricted stock units are recorded as a liability within the Consolidated Balance Sheets and are adjusted to fair value each reporting period.

No restricted awards vested during the three-month periods ended March 31, 2015 and March 31, 2014. When restricted awards vest, we withhold shares based on the closing stock price on the vesting date to settle the employees' minimum statutory obligation for the applicable income and other employment taxes. Total cash remitted for the employees' tax obligations to the relevant taxing authorities is reflected as a financing activity within the Consolidated Statements of Cash Flows, and the shares withheld to satisfy the minimum tax withholding obligations are recorded as treasury stock.

Performance Awards

Performance awards entitle the recipient to shares of common stock upon attainment of performance objectives as pre-established by the Compensation Committee. If the performance objectives are achieved, performance awards currently outstanding vest, subject to continued employment, over periods ranging from 12 to 60 months from the grant date of the award. The performance awards do not confer any voting or dividend rights to recipients until such shares vest and do not have any post-vesting sales restrictions.

The following table summarizes performance award activity for the three months ended March 31, 2015:



	Number of Performance Awards (in thousands)		Weighted Average Grant Date Fair Value ($)
Nonvested at beginning of period	183		$	25.06
Granted	202		28.79
Vested	(37	)	25.06
Forfeited	—		—
Nonvested at end of period	348		27.22

We granted performance awards (in thousands) totaling 202 shares and 183 shares during the three-month periods ended March 31, 2015 and March 31, 2014, respectively. The performance awards are earned based upon the level of attainment by the Company of specified performance objectives related to earnings per share for the fiscal year, as established by the Compensation Committee. The number of shares which are ultimately earned for the 2015 awards will range from 0 percent to 132 percent of the target number based on the level of attainment of the performance objectives and ranged from 0 percent to 133 percent for the 2014 awards. We estimate the fair value of performance awards based upon the market price of the underlying common stock on the date of grant, reduced by the present value of estimated future dividends because the awards are not entitled to receive dividends prior to vesting. Our estimate of future dividends is based on the most recent quarterly dividend rate at the time of grant, adjusted for any known future changes in the dividend rate.

The present value of estimated future dividends was calculated using the following assumptions:



	Three Months Ended March 31,
	2015			2014
Dividends per share (quarterly amounts)	$	0.05		$	0.05
Risk-free interest rate	1.6		%	1.5		%

During the three-month period ended March 31, 2015, the Compensation Committee determined that the 2014 fiscal year performance objectives were achieved at the target level and 182,813 shares of common stock were earned, subject to time-based vesting. The vesting date fair value of the performance awards vested during the three-month period ended March 31, 2015 was $1.1 million. We withheld shares based on the closing stock price on the vesting date to settle the employees' minimum statutory obligation for the applicable income and other employment taxes. Total cash remitted for employees' tax obligations to the relevant taxing authorities is reflected as a financing activity within the Consolidated Statements of Cash Flows, and the shares withheld to satisfy the minimum tax withholding obligations are recorded as treasury stock.
