FINANCIAL INFORMATION

Cautionary Note Regarding Forward-Looking Statements:

This Quarterly Report on Form 10-Q contains historical information and forward-looking statements based on information currently available to our management. The forward-looking statements in this report, including those made in Item 2 (Management’s Discussion and Analysis of Financial Condition and Results of Operations) of Part I, are made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, as amended. These safe harbor provisions encourage reporting companies to provide prospective information to investors. Forward-looking statements can be identified by the use of certain words, such as “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “project” and other similar terms and language. We believe the forward-looking statements are reasonable based on currently available information. However, forward-looking statements involve risks, uncertainties and assumptions, whether known or unknown, that could cause our actual results, business, financial condition and cash flows to differ materially from those anticipated in the forward-looking statements. A discussion of important factors relating to forward-looking statements is included in Item 1A (Risk Factors) of Part I of our Annual Report on Form 10-K for the year ended December 31, 2014 (“2014 Form 10-K”). Readers should not unduly rely on the forward-looking statements included in this Form 10-Q because such statements speak only to the date they were made. Unless otherwise required by applicable securities laws, we undertake no obligation or duty to update or revise any forward-looking statements contained herein to reflect subsequent events or circumstances or the occurrence of unanticipated events.

Item 1. Financial Statements.

The interim consolidated financial statements contained herein reflect all adjustments which, in the opinion of management, are necessary for a fair statement of the financial condition, results of operations and cash flows for the periods presented. The interim consolidated financial statements have been prepared in accordance with the U.S. Securities and Exchange Commission (“SEC”) instructions to Form 10-Q and were also prepared without audit. The interim consolidated financial statements do not include all information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements; although in management’s opinion, the disclosures are adequate so that the information presented is not misleading.

Operating results for the three-month and six-month periods ended June 30, 2015, are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. In the opinion of management, the information set forth in the accompanying consolidated condensed balance sheets is fairly stated in all material respects in relation to the consolidated balance sheets from which it has been derived.

These interim consolidated financial statements and notes thereto should be read in conjunction with the consolidated financial statements and accompanying notes contained in our 2014 Form 10-K.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

(1) Credit Facilities

As of June 30, 2015, we had unsecured committed credit facilities with two banks as well as a term commitment with one of these banks. We had with Wells Fargo Bank, N.A., a $175.0 million credit facility which was set to expire on May 31, 2016, and a $75.0 million term commitment with principal due and payable on September 15, 2019. We also had a $75.0 million credit facility with BMO Harris Bank N.A., which will expire on March 5, 2020. Borrowings under these credit facilities and term note bear variable interest (0.7855% at June 30, 2015) based on the London Interbank Offered Rate (“LIBOR”), with interest on the term note effectively fixed at 2.5% with an interest rate swap agreement.

On July 13, 2015, we amended our existing credit agreement, dated June 1, 2012, as previously amended, with Wells Fargo Bank, N.A. This amendment lowered the maximum principal amount of the unsecured line of credit to $100.0 million from $175.0 million and extended the term of the credit agreement to July 12, 2020 from May 31, 2016. Also on July 13, 2015, we entered into a new credit agreement with U.S. Bank N.A. The new credit agreement is an unsecured line of credit of $75.0 million and expires on July 13, 2020.

As of June 30, 2015, and December 31, 2014, our outstanding debt totaled $75.0 million. The $325.0 million of credit available under these facilities at June 30, 2015, is further reduced by $32.7 million in stand-by letters of credit under which we are obligated. Each of the debt agreements in effect at June 30, 2015 includes, among other things, two financial covenants requiring us (i) not to exceed a maximum ratio of total debt to total capitalization and (ii) not to exceed a maximum ratio of total funded debt to earnings before interest, income taxes, depreciation and amortization (as such terms are defined in each credit facility). At June 30, 2015, we were in compliance with these covenants.

At June 30, 2015, the aggregate future maturities of long-term debt by year are as follows (in thousands):

2015	$	—
2016	—
2017	—
2018	—
2019	75,000
Total	$	75,000

The carrying amounts of our long-term debt approximate fair value due to the duration of the notes and the variable interest rates.

(2) Income Taxes

For the three-month and six-month periods ended June 30, 2015, there were no material changes to the total amount of unrecognized tax benefits. We accrued interest expense of $65 thousand and $64 thousand during the three-month periods ended June 30, 2015 and June 30, 2014, respectively, and $124 thousand and $122 thousand during the six-month periods ended June 30, 2015, and June 30, 2014, respectively, excluding the reversal of accrued interest related to adjustments for the remeasurement of uncertain tax positions. Our total gross liability for unrecognized tax benefits at June 30, 2015, is $9.1 million. If recognized, $5.8 million of unrecognized tax benefits would impact our effective tax rate. Interest of $1.8 million has been reflected as a component of the total liability. We expect no other significant increases or decreases for uncertain tax positions during the next twelve months.

We file U.S. federal income tax returns, as well as income tax returns in various states and several foreign jurisdictions. The years 2011 through 2014 are open for examination by the Internal Revenue Service (“IRS”), and various years are open for examination by state and foreign tax authorities. State and foreign jurisdictional statutes of limitations generally range from three to four years.

(3) Commitments and Contingencies

As of June 30, 2015, we have committed to property and equipment purchases of approximately $172.5 million.

We are involved in certain claims and pending litigation arising in the ordinary course of business. At this time, management believes the ultimate resolution of these matters will not materially affect our consolidated financial statements.

8

(4) Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options and restricted stock awards. There are no differences in the numerators of our computations of basic and diluted earnings per share for any period presented.

The computation of basic and diluted earnings per share is shown below (in thousands, except per share amounts).

	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Net income	$	31,848	$	25,632	$	54,990	$	39,971
Weighted average common shares outstanding	71,945		72,091		72,005		72,382
Dilutive effect of stock-based awards	479		506		477		500
Shares used in computing diluted earnings per share	72,424		72,597		72,482		72,882
Basic earnings per share	$	0.44	$	0.36	$	0.76	$	0.55
Diluted earnings per share	$	0.44	$	0.35	$	0.76	$	0.55

There were no options to purchase shares of common stock that were outstanding during the periods indicated above that were excluded from the computation of diluted earnings per share because the option purchase price was greater than the average market price of the common shares during the period. Performance awards are excluded from the calculation of dilutive potential common shares until the threshold performance conditions have been satisfied.

(5) 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 June 30, 2015, there were 7,183,373 shares available for granting additional awards.

Equity compensation expense is included in salaries, wages and benefits within the Consolidated Statements of Income. As of June 30, 2015, the total unrecognized compensation cost related to non-vested equity compensation awards was approximately $12.5 million and is expected to be recognized over a weighted average period of 2.5 years.

9

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

	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Stock options:
Pre-tax compensation expense	$	17	$	30	$	34	$	60
Tax benefit	6		12		13		24
Stock option expense, net of tax	$	11	$	18	$	21	$	36
Restricted awards:
Pre-tax compensation expense	$	1,024	$	1,080	$	2,041	$	2,075
Tax benefit	404		434		806		835
Restricted award expense, net of tax	$	620	$	646	$	1,235	$	1,240
Performance awards:
Pre-tax compensation expense	$	953	$	431	$	1,708	$	717
Tax benefit	377		174		675		289
Performance award expense, net of tax	$	576	$	257	$	1,033	$	428

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 six months ended June 30, 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	(44	)	17.44
Forfeited	(5	)	20.33
Expired	—		—
Outstanding at end of period	199		18.28		3.45	$	1,587
Exercisable at end of period	157		17.78		3.00	$	1,332

We did not grant any stock options during the three-month and six-month periods ended June 30, 2015 and June 30, 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 $1.9 million for the six-month periods ended June 30, 2015 and June 30, 2014.

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.

10

The following table summarizes restricted award activity for the six months ended June 30, 2015:

	Number of Restricted Awards (in thousands)		Weighted Average Grant Date Fair Value ($)
Nonvested at beginning of period	643		$	22.92
Granted	—		—
Vested	(2	)	24.21
Forfeited	(17	)	24.07
Nonvested at end of period	624		22.88

We did not grant any restricted awards during the three-month and six-month periods ended June 30, 2015 and granted 10,000 shares of restricted stock during the three-month and six-month periods ended June 30, 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. The present value of estimated future dividends for the 2014 grants was calculated using the following weighted-average assumptions:

Dividends per share (quarterly amounts)	$	0.05
Risk-free interest rate	1.5		%

The total fair value of previously granted restricted awards vested during the three-month and six-month periods ended June 30, 2015 was $70 thousand and for the three-month and six-month periods ended June 30, 2014 was $90 thousand. 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 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 six months ended June 30, 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 did not grant any performance awards during the three-month periods ended June 30, 2015 and June 30, 2014, respectively, and granted performance awards (in thousands) totaling 202 shares and 183 shares during the six-month periods ended June 30, 2015 and June 30, 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

11

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:

	Six Months Ended June 30,
	2015			2014
Dividends per share (quarterly amounts)	$	0.05		$	0.05
Risk-free interest rate	1.6		%	1.5		%

During the six-month period ended June 30, 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 six-month period ended June 30, 2015 was $1.1 million. 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 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.

(6) Segment Information

We have two reportable segments – Truckload Transportation Services (“Truckload”) and Value Added Services (“VAS”).

The Truckload segment consists of two operating units, One-Way Truckload and Specialized Services, that are aggregated because they have similar economic characteristics and meet the other aggregation criteria described in the accounting guidance for segment reporting. One-Way Truckload is comprised of the following operating fleets: (i) the regional short-haul (“Regional”) fleet transports a variety of consumer nondurable products and other commodities in truckload quantities within geographic regions across the United States using dry van trailers; (ii) the medium-to-long-haul van (“Van”) fleet provides comparable truckload van service over irregular routes; and (iii) the expedited (“Expedited”) fleet provides time-sensitive truckload services utilizing driver teams. Specialized Services provides truckload services dedicated to a specific customer, generally for a retail distribution center or manufacturing facility, including services for products requiring specialized trailers such as flatbed or temperature-controlled trailers. Revenues for the Truckload segment include a small amount of non-trucking revenues which consist primarily of the portion of shipments delivered to or from Mexico where we utilize a third-party capacity provider.

The VAS segment generates the majority of our non-trucking revenues through four operating units that provide non-trucking services to our customers. These four VAS operating units are as follows: (i) truck brokerage (“Brokerage”) uses contracted carriers to complete customer shipments; (ii) freight management (“Freight Management”) offers a full range of single-source logistics management services and solutions; (iii) the intermodal (“Intermodal”) unit offers rail transportation through alliances with rail and drayage providers as an alternative to truck transportation; and (iv) Werner Global Logistics international (“WGL”) provides complete management of global shipments from origin to destination using a combination of air, ocean, truck and rail transportation modes.

We generate other revenues from transportation-related activities such as third-party equipment maintenance and equipment leasing and other business activities. None of these operations meets the quantitative reporting thresholds. As a result, these operations are grouped in “Other” in the table below. “Corporate” includes revenues and expenses that are incidental to our activities and are not attributable to any of our operating segments. We do not prepare separate balance sheets by segment and, as a result, assets are not separately identifiable by segment. Inter-segment eliminations in the table below represent transactions between reporting segments that are eliminated in consolidation.

(7) Derivative Financial Instrument

In the normal course of business we are subject to risk from adverse fluctuations in foreign exchange and interest rates and commodity prices. We manage our risks for interest rate changes through use of an interest rate swap. At June 30, 2015, we had one interest rate swap outstanding, which matures in September 2019, with a notional value of $75.0 million and a fair value loss of $1.5 million. The counterparty to this contract is a major financial institution. We are exposed to credit loss in the event of non-performance by the counterparty. We do not use derivative instruments for trading or speculative purposes and have no derivative financial instruments to reduce our exposure to fuel price fluctuations.

Our objective in managing exposure to interest rate risk is to limit the impact on earnings and cash flow. The extent to which we use such instruments is dependent on our access to these contracts in the financial markets and our success using other methods.

Our outstanding derivative financial instrument is recognized as an other long-term liability in the Consolidated Balance Sheets at fair value. The interest rate swap is accounted for as a cash flow hedging instrument. At inception, we formally designated and documented the financial instrument as a hedge of a specific underlying exposure, the risk management objective, and the manner in which effectiveness of the hedge will be assessed. We formally assess, both at inception and at each reporting period thereafter, whether the derivative financial instrument is effective in offsetting changes in cash flows of the related underlying exposure. All changes in fair value of outstanding derivatives in cash flow hedges, except any ineffective portion, are recorded in other comprehensive income until earnings are impacted by the hedged transaction. Classification of the gain or loss in the Consolidated Statements of Income upon release from comprehensive income is the same as that of the underlying exposure. Any ineffective portion of the change in fair value of the instruments is recognized immediately in earnings.

We will discontinue the use of hedge accounting prospectively when (i) the derivative instrument is no longer effective in offsetting changes in fair value or cash flows of the underlying hedged item; (ii) the derivative instrument expires, is sold, terminated or exercised; or (iii) designating the derivative instrument as a hedge is no longer appropriate.

Should we discontinue hedge accounting because it is no longer probable that an anticipated transaction will occur in the originally expected period, or within an additional two-month period thereafter, changes to fair value accumulated in other comprehensive income would be recognized immediately in earnings.

FASB ASC 815-10 requires companies to recognize the derivative instrument as an asset or a liability at fair value in the statement of financial position. Fair value of the derivative instrument is required to be measured under the FASB’s Fair Value Measurements and Disclosures guidance, which establishes a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs

13

classified within Level 3 of the hierarchy). Level 1 inputs use quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. The fair value of our interest rate swap is based on Level 2 inputs.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Management’s Discussion and Analysis of Financial Condition and Results of Operations (the “MD&A”) summarizes the financial statements from management’s perspective with respect to our financial condition, results of operations, liquidity and other factors that may affect actual results. The MD&A is organized in the following sections:

• Overview

• Results of Operations

• Liquidity and Capital Resources

• Contractual Obligations and Commercial Commitments

• Off-Balance Sheet Arrangements

• Regulations

• Critical Accounting Policies and Estimates

• Accounting Standards

The MD&A should be read in conjunction with our 2014 Form 10-K.

Overview:

We have two reportable segments, Truckload Transportation Services ("Truckload") and Value Added Services ("VAS"), and we operate in the truckload and logistics sectors of the transportation industry. In the truckload sector, we focus on transporting consumer nondurable products that generally ship more consistently throughout the year. In the logistics sector, besides managing transportation requirements for individual customers, we provide additional sources of truck capacity, alternative modes of transportation, a global delivery network and systems analysis to optimize transportation needs. Our success depends on our ability to efficiently and effectively manage our resources in the delivery of truckload transportation and logistics services to our customers. Resource requirements vary with customer demand, which may be subject to seasonal or general economic conditions. Our ability to adapt to changes in customer transportation requirements is essential to efficiently deploy resources and make capital investments in tractors and trailers (with respect to our Truckload segment) or obtain qualified third-party capacity at a reasonable price (with respect to our VAS segment). Although our business volume is not highly concentrated in certain customers or goods, we may also be affected by our customers’ financial failures or loss of customer business.

Revenues for our Truckload segment operating units (One-Way Truckload and Specialized Services) are typically generated on a per-mile basis and also include revenues such as stop charges, loading and unloading charges, equipment detention charges and equipment repositioning charges. To mitigate our risk to fuel price increases, we recover from our customers additional fuel surcharges that generally recoup a majority of the increased fuel costs; however, we cannot assure that current recovery levels will continue in future periods. Because fuel surcharge revenues fluctuate in response to changes in fuel costs, we identify them separately and exclude them from the statistical calculations to provide a more meaningful comparison between periods. The key statistics used to evaluate trucking revenues, net of fuel surcharge, are (i) average revenues per tractor per week, (ii) average percentage of empty miles (miles without trailer cargo), (iii) average trip length (in loaded miles) and (iv) average number of tractors in service. General economic conditions, seasonal trucking industry freight patterns and industry capacity are important factors that impact these statistics. Our Truckload segment also generates a small amount of revenues categorized as non-trucking revenues, related to shipments delivered to or from Mexico where the Truckload segment utilizes a third-party capacity provider. We exclude such revenues from the statistical calculations.

Our most significant resource requirements are company drivers, independent contractors, tractors and trailers. Independent contractors supply their own tractors and drivers and are responsible for their operating expenses. Our financial results are affected by company driver and independent contractor availability and the markets for new and used revenue equipment. We are self-insured for a significant portion of bodily injury, property damage and cargo claims; workers’ compensation claims; and associate health claims (supplemented by premium-based insurance coverage above certain dollar levels). For that reason, our financial results may also be affected by driver safety, medical costs, weather, legal and regulatory environments and insurance coverage costs to protect against catastrophic losses.

The operating ratio is a common industry measure used to evaluate our profitability and that of our Truckload segment operating fleets. The operating ratio consists of operating expenses expressed as a percentage of operating revenues. The most significant variable expenses that impact the Truckload segment are driver salaries and benefits, fuel, fuel taxes (included in taxes and licenses expense), payments to independent contractors (included in rent and purchased transportation expense), supplies and maintenance and insurance and claims. As discussed further in the comparison of operating results for second quarter 2015 to second quarter 2014, several industry-wide issues have caused, and could continue to cause, costs to increase in future periods. These issues include shortages of drivers or independent contractors, changing fuel prices, higher new truck and trailer purchase prices and compliance with new or proposed regulations. Our main fixed costs include depreciation expense for tractors and trailers and equipment licensing fees (included in taxes and licenses expense). The Truckload segment requires substantial cash

15

expenditures for tractor and trailer purchases. We fund these purchases with net cash from operations and financing available under our existing credit facilities, as management deems necessary.

We provide non-trucking services primarily through the four operating units within our VAS segment (Brokerage, Freight Management, Intermodal and Werner Global Logistics international). Unlike our Truckload segment, the VAS segment is less asset-intensive and is instead dependent upon qualified associates, information systems and qualified third-party capacity providers. The largest expense item related to the VAS segment is the cost of purchased transportation we pay to third-party capacity providers. This expense item is recorded as rent and purchased transportation expense. Other operating expenses consist primarily of salaries, wages and benefits. We evaluate the VAS segment's financial performance by reviewing the gross margin percentage (revenues less rent and purchased transportation expenses expressed as a percentage of revenues) and the operating income percentage. The gross margin percentage can be impacted by the rates charged to customers and the costs of securing third-party capacity. We have a mix of contracted long-term rates and variable rates for the cost of third-party capacity, and we cannot assure that our operating results will not be adversely impacted in the future if our ability to obtain qualified third-party capacity providers changes or the rates of such providers increase.

Three Months Ended June 30, 2015 Compared to Three Months Ended June 30, 2014

Operating Revenues

Operating revenues decreased 1.4% for the three months ended June 30, 2015, compared to the same period of the prior year. When comparing second quarter 2015 to second quarter 2014, Truckload segment revenues decreased $12.4 million or 2.9% because of lower fuel surcharge revenues, and VAS revenues increased $2.9 million or 2.9%.

Freight demand in second quarter 2015 and July 2015 continued to be the strongest of the last five years, with the exception of the same period in 2014 which was rebounding from severe winter weather in first quarter 2014 that temporarily backed up the freight network.

We believe constrained truck capacity combined with a gradually improving economy in the retail, consumer products and grocery products markets primarily served by us are contributing to strong freight demand. Truckload industry capacity is being challenged by an extremely competitive driver recruiting market and heightened regulatory cost increases for safety and truck ownership; we expect this trend will continue. There are numerous pending and proposed federal safety initiatives that could further limit truckload and driver capacity in the next few years, including mandatory electronic logging devices (ELD’s), a national drug and alcohol driver data base, increased minimum liability insurance requirements for carriers, more sophisticated drug screening procedures for drivers and mandatory truck speed limiter devices.

Trucking revenues, net of fuel surcharge, increased 6.3% in second quarter 2015 compared to second quarter 2014 due to a 3.5% increase in average revenues per tractor per week, net of fuel surcharge, and a 2.7% increase in the average number of tractors in service. Continued focus on securing driver friendly, highly productive freight and improved freight selection using our proprietary freight optimization system enabled us to maintain our average miles per truck in a strong, but not as strong a freight market as second quarter 2014. Our average miles per truck declined slightly by 0.2% in second quarter 2015 compared to second quarter 2014. Average revenues per total mile, net of fuel surcharge, increased 3.8% in second quarter 2015 compared to second quarter 2014.

We believe that we are making continued progress implementing sustainable rate increases with our customers. These efforts are ongoing as we move forward in 2015 and work to recoup the cost increases associated with more expensive equipment, a shrinking supply of qualified drivers and an increasingly challenging regulatory environment.

The average number of tractors in service in the Truckload segment increased 2.7% to 7,247 in second quarter 2015 from 7,055 in second quarter 2014. On the strength of an intense company-wide focus to improve our driver recruiting and retention, we ended second quarter 2015 with 7,275 trucks in the Truckload segment, a sequential improvement of 165 trucks compared to first quarter 2015 and a year-over-year improvement of 240 trucks compared to second quarter 2014. In mid-August 2014, we increased pay by varying percentage amounts for many drivers in certain fleets within our One-Way Truckload unit. After these driver pay changes, our driver and truck count increased from July 2014 levels. Additionally, over the last several quarters, we increased driver pay in multiple Dedicated fleets, most of which were funded by customer rate increases to ensure truck capacity. We cannot predict whether future driver shortages, if any, will adversely affect our ability to maintain our fleet size. If such a driver market shortage were to occur, it could result in a fleet size reduction, and our results of operations could be adversely affected.

Trucking fuel surcharge revenues represent collections from customers for the increase in fuel and fuel-related expenses, including the fuel component of our independent contractor cost (recorded as rent and purchased transportation expense) and fuel taxes (recorded in taxes and licenses expense), when diesel fuel prices rise. Conversely, when fuel prices decrease, fuel surcharge revenues decrease. These revenues decreased 37.1% to $58.3 million in second quarter 2015 from $92.7 million in second quarter 2014 due to lower average fuel prices in the 2015 quarter. To lessen the effect of fluctuating fuel prices on our margins, we collect fuel surcharge revenues from our customers for the cost of diesel fuel and taxes in excess of specified base fuel price levels according to terms in our customer contracts. Fuel surcharge rates generally adjust weekly based on an independent U.S. Department of Energy fuel price survey which is released every Monday. Our fuel surcharge programs are designed to (i) recoup higher fuel costs from customers when fuel prices rise and (ii) provide customers with the benefit of lower fuel costs when fuel prices decline. These programs generally enable us to recover a majority, but not all, of the fuel price increases. The remaining portion is generally not recoverable because it results from empty and out-of-route miles (which are not billable to customers) and truck idle time. Fuel prices that change rapidly in short time periods also impact our recovery because the surcharge rate in most programs only changes once per week.

VAS revenues are generated by its four operating units and exclude revenues for full truckload shipments transferred to the Truckload segment, which are recorded as trucking revenues by the Truckload segment. VAS also recorded revenue and brokered freight expense of $0.5 million in second quarter 2015 and $0.9 million in second quarter 2014 for Intermodal drayage movements performed by the Truckload segment (also recorded as trucking revenue by the Truckload segment), and these transactions between reporting segments are eliminated in consolidation. In second quarter 2015, VAS revenues increased $2.9 million or 2.9%, and

18

operating income dollars increased $2.7 million or 121.9%, compared to second quarter 2014. VAS revenue growth was reduced due in part to significantly lower fuel prices in second quarter 2015 compared to second quarter 2014 which decreased VAS revenues. Our on-going efforts to address customer pricing, contractual and operational issues within VAS resulted in the best quarterly gross margin and operating income percentages since second quarter 2013. The VAS gross margin percentage in second quarter 2015 of 15.5% improved year over year compared to the gross margin percentage of 13.2% in second quarter 2014 and also improved sequentially from the 14.3% gross margin in first quarter 2015. The VAS operating income percentage in second quarter 2015 of 4.8% improved from second quarter 2014 of 2.2% and first quarter 2015 of 2.7%.

Operating Expenses

Our operating ratio (operating expenses expressed as a percentage of operating revenues) was 90.2% for the three months ended June 30, 2015, compared to 92.2% for the three months ended June 30, 2014. Expense items that impacted the overall operating ratio are described on the following pages. The tables on pages 16 and 17 show the Consolidated Statements of Income in dollars and as a percentage of total operating revenues and the percentage increase or decrease in the dollar amounts of those items compared to the same quarter of the prior year, as well as the operating ratios, operating margins, and certain statistical information for our two reportable segments, Truckload and VAS.

Salaries, wages and benefits increased $15.9 million or 11.0% in second quarter 2015 compared to second quarter 2014 and increased 3.3% as a percentage of operating revenues to 30.0%. The higher dollar amount of salaries, wages and benefits expense was due primarily to higher driver and non-driver salaries and payroll related fringe benefits. When evaluated on a per-mile basis, driver and non-driver salaries, wages and benefits increased as well, which we primarily attribute to higher driver pay which increased 10%. In mid-August 2014, we increased pay by varying percentage amounts for many drivers within our One-Way Truckload unit. Additionally, over the last several quarters, we increased driver pay in multiple Dedicated fleets, most of which were funded by customer rate increases to ensure capacity. Non-driver salaries, wages and benefits in the non-trucking VAS segment increased 1.4%.

We renewed our workers' compensation insurance coverage for the policy year beginning April 1, 2015. Our coverage levels are the same as the prior policy year. We continue to maintain a self-insurance retention of $1.0 million per claim. Our workers’ compensation insurance premiums for the policy year beginning April 2015 were similar to those for the previous policy year.

The driver recruiting market remained very challenging during second quarter 2015. Several difficult market factors persist including a declining number of, and increased competition for, driver training school graduates, a gradually declining national unemployment rate, aging truck driver demographics and increased truck safety regulations. Beginning with the second half of 2014, many large truckload carriers, including Werner, increased driver pay rates per mile and achieved mileage productivity improvements. This led to lower driver turnover and a more competitive driver recruiting market. We are unable to predict whether we will experience future driver shortages. If such a shortage were to occur and additional driver pay rate increases became necessary to attract and retain drivers, our results of operations would be negatively impacted to the extent that we could not obtain corresponding freight rate increases.

Fuel decreased $34.8 million or 37.7% in second quarter 2015 compared to second quarter 2014 and decreased 6.3% as a percentage of operating revenues due primarily to lower average diesel fuel prices. Average diesel fuel prices were $1.15 per gallon lower in second quarter 2015 than in second quarter 2014.

We continue to employ measures to improve our fuel miles per gallon (“mpg”) such as (i) limiting truck engine idle time, (ii) optimizing the speed, weight and specifications of our equipment and (iii) implementing mpg-enhancing equipment changes to our fleet including new trucks with U.S. Environmental Protection Agency (the “EPA”) 2010 compliant engines, more aerodynamic truck features, idle reduction systems, trailer tire inflation systems, trailer skirts and automated manual transmissions to reduce our fuel gallons purchased. However, fuel savings from mpg improvement is offset by higher depreciation expense and the additional cost of diesel exhaust fluid (required in tractors with engines that meet the 2010 EPA emission standards). Although our fuel management programs require significant capital investment and research and development, we intend to continue these and other environmentally conscious initiatives, including our active participation as an EPA SmartWay Transport Partner. The SmartWay Transport Partnership is a national voluntary program developed by the EPA and freight industry representatives to reduce greenhouse gases and air pollution and promote cleaner, more efficient ground freight transportation.

For July 2015, the average diesel fuel price per gallon was approximately $1.20 lower than the average diesel fuel price per gallon in the same period of 2014 and approximately $1.16 lower than in third quarter 2014.

Shortages of fuel, increases in fuel prices and petroleum product rationing can have a materially adverse effect on our operations and profitability. We are unable to predict whether fuel price levels will increase or decrease in the future or the extent to which fuel surcharges will be collected from customers. As of June 30, 2015, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.

19

Supplies and maintenance increased $0.5 million or 1.1% in second quarter 2015 compared to second quarter 2014 and increased 0.2% as a percentage of operating revenues. Higher company driver miles in second quarter 2015 compared to second quarter 2014 were primarily responsible for the increase in supplies and maintenance. The average age of our company truck fleet was 2.0 years at the end of second quarter 2015, 2.4 years at the end of second quarter of 2014 and 2.1 years at the end of first quarter 2015.

Taxes and licenses increased $1.5 million or 6.8% in second quarter 2015 compared to second quarter 2014 and increased 0.4% as a percentage of operating revenues. The increase resulted from a higher truck count, driving more miles in second quarter 2015 than in second quarter 2014 and an increase in property taxes.

Insurance and claims increased $1.4 million or 7.5% in second quarter 2015 compared to second quarter 2014 and increased 0.3% as a percentage of operating revenues. The increase in second quarter 2015 compared to second quarter 2014 was primarily the result of new smaller dollar liability claims that occurred during the 2015 quarter. The majority of our insurance and claims expense results from our claim experience and claim development under our self-insurance program; the remainder results from insurance premiums for claims in excess of our self-insured limits. We renewed our liability insurance policies on August 1, 2015 and continued to be responsible for the first $2.0 million per claim with an annual $8.0 million aggregate for claims between $2.0 million and $5.0 million and an annual aggregate of $5.0 million for claims in excess of $5.0 million and less than $10.0 million. We maintain liability insurance coverage with insurance carriers substantially in excess of the $10.0 million per claim. Our liability and cargo insurance premiums for the policy year that began August 1, 2015 are slightly lower than premiums for the previous policy year on a per-mile basis.

Depreciation expense increased $3.7 million or 8.3% in second quarter 2015 compared to second quarter 2014 and increased 0.8% as a percentage of operating revenues. This increase was due primarily to the higher cost of new trucks purchased compared to the cost of used trucks that were sold over the past 12 months, as well as the growth in company trucks. In addition, the purchase of new trailers over the past 12 months to replace older used trailers which were fully depreciated also contributed to the increase in depreciation expense.

Depreciation expense has been historically affected by a series of changes to engine emissions standards imposed by the EPA that became effective in October 2002, January 2007 and January 2010, resulting in increased truck purchase costs. Trucks with 2010-standard engines have a higher purchase price than trucks manufactured to meet the 2007 standards, but the 2010-standard engines are more fuel efficient. As of June 30, 2015, nearly all company trucks had engines that comply with the 2010 emissions standards.

Rent and purchased transportation expense decreased $3.3 million or 2.6% in second quarter 2015 compared to second quarter 2014 and decreased 0.3% as a percentage of operating revenues. Rent and purchased transportation expense consists mostly of payments to third-party capacity providers in the VAS segment and other non-trucking operations and payments to independent contractors in the Truckload segment. The payments to third-party capacity providers generally vary depending on changes in the volume of services generated by the VAS segment. VAS rent and purchased transportation expense increased $0.2 million but as a percentage of VAS revenues decreased to 84.5% in second quarter 2015 from 86.8% in second quarter 2014. This improved gross margin percentage was due primarily to our on-going efforts to address customer pricing, contractual and operational issues with VAS.

Rent and purchased transportation for the Truckload segment decreased $3.9 million in second quarter 2015 compared to second quarter 2014. This decrease is due primarily to lower fuel prices that resulted in lower reimbursements to independent contractors for fuel and lower independent contractor miles in second quarter 2015 compared to second quarter 2014, offset partially by a higher average settlement rate per mile. In mid-August 2014, we increased the per-mile settlement rate for certain owner-operators. Independent contractor miles as a percentage of total miles were 11.6% in second quarter 2015 compared to 12.4% in second quarter 2014.

Challenging operating conditions continue to make independent contractor recruitment and retention difficult. Such conditions include inflationary cost increases that are the responsibility of independent contractors and a shortage of financing available to independent contractors for equipment purchases. We have historically been able to add company tractors and recruit additional company drivers to offset any decrease in the number of independent contractors. If a shortage of independent contractors and company drivers occurs, further increases in per-mile settlement rates (for independent contractors) and driver pay rates (for company drivers) may become necessary to attract and retain these drivers. This could negatively affect our results of operations to the extent that we would not be able to obtain corresponding freight rate increases.

Communication and utilities increased $0.4 million or 12.6% in second quarter 2015 compared to second quarter 2014 and increased 0.1% as a percentage of operating revenues. This increase is primarily due to higher communications costs in second quarter 2015 compared to second quarter 2014.

20

Other operating expenses decreased $2.7 million in second quarter 2015 compared to second quarter 2014 and decreased 0.5% as a percentage of operating revenues. Gains on sales of assets (primarily used trucks and trailers) are reflected as a reduction of other operating expenses and are reported net of sales-related expenses (which include costs to prepare the equipment for sale). Gains on sales of assets increased to $6.7 million in second quarter 2015 from $5.2 million in second quarter 2014, which included a $1.6 million gain from the sale of real estate. In second quarter 2015, we realized higher average gains per truck and trailer and sold more trucks and trailers than in second quarter 2014.

Other Expense (Income)

Other expense (income) increased $0.6 million in second quarter 2015 compared to second quarter 2014 and increased 0.1% as a percentage of operating revenues. Interest expense was higher in second quarter 2015 compared to second quarter 2014 because we had a higher amount of average debt outstanding. We entered into an interest rate swap agreement in September 2014 that effectively fixed our interest rate at 2.5% for five years on debt of $75 million.

Income Taxes

Our effective income tax rate (income taxes expressed as a percentage of income before income taxes) decreased to 39.0% for second quarter 2015 from 40.25% for second quarter 2014. The lower income tax rate for second quarter 2015 is attributed to lower projected non-deductible expenses and lower state income taxes, as well as certain state income tax refunds for prior periods.

Six Months Ended June 30, 2015 Compared to Six Months Ended June 30, 2014

Operating Revenues

Operating revenues decreased 0.4% for the six months ended June 30, 2015, compared to the same period of the prior year. In the Truckload segment, trucking revenues, net of fuel surcharge, increased 6.0% in the 2015 year-to-date period compared to the 2014 year-to-date period due primarily to a 4.5% increase in average revenues per tractor per week and a 1.4% increase in the average number of tractors in service. Average revenues per total mile, net of fuel surcharge, increased 3.6% in the first half of 2015 compared to the same period in 2014, and average monthly miles per tractor increased by 0.9%. Truckload segment fuel surcharge revenues for the six months ended June 30, 2015 decreased $65.0 million or 36.2% when compared to the six months ended June 30, 2014 due to lower average fuel prices in the 2015 period. VAS revenues increased 4.7%, from $185.7 million in the first six months of 2014 to $194.3 million in the same 2015 period. VAS revenue growth was reduced due in part to significantly lower fuel prices in this first six months of 2015 compared to the first six months of 2014 which decreased VAS revenues.

Operating Expenses

Our operating ratio (operating expenses expressed as a percentage of operating revenues) was 91.2% for the six months ended June 30 , 2015, compared to 93.6% for the six months ended June 30, 2014. Expense items that impacted the overall operating ratio are described on the following pages. The tables on pages 16 and 17 show the Consolidated Statements of Income in dollars and as a percentage of total operating revenues and the percentage increase or decrease in the dollar amounts of those items compared to the same period of the prior year, as well as the operating ratios, operating margins, and certain statistical information for our two reportable segments, Truckload and VAS.

Salaries, wages and benefits increased $32.6 million or 11.7% in the first six months of 2015 compared to the first six months of 2014 and increased 3.3% as a percentage of operating revenues to 30.3%. The higher dollar amount of salaries, wages and benefits expense was due primarily to higher driver and non-driver salaries and payroll related fringe benefits. When evaluated on a per-mile basis, driver and non-driver salaries, wages and benefits increased as well, which we primarily attribute to higher driver pay. Non-driver salaries, wages and benefits in the non-trucking VAS segment decreased 1.5%.

Fuel decreased $73.1 million or 39.9% in the first six months of 2015 compared to the same period in 2014 and decreased 7.0% as a percentage of operating revenues due primarily to lower average diesel fuel prices. Average diesel fuel prices were $1.23 per gallon lower in the first six months of 2015 than in the same 2014 period.

Supplies and maintenance increased $2.3 million or 2.5% in the first six months of 2015 compared to the same period in 2014 and increased 0.2% as a percentage of operating revenues. Increased driver advertising and other driver related expenses and higher company driver miles in the first six months of 2015 compared to same period in 2014 were primarily responsible for the increase in supplies and maintenance.

Taxes and licenses increased $1.7 million or 4.0% in the first six months of 2015 compared to the same 2014 period and increased 0.3% as a percentage of operating revenues. The increase resulted from a higher company truck count, driving more miles in the year-to-date 2015 period and an increase in property taxes.

21

Insurance and claims increased $3.3 million or 8.3% in the first six months of 2015 compared to the same period in 2014 and increased 0.3% as a percentage of operating revenues due primarily to the higher costs related to large dollar liability claims.

Depreciation expense increased $6.3 million or 7.2% in the first six months of 2015 compared to the same 2014 period and increased 0.6% as a percentage of operating revenues due primarily to the higher cost of new trucks purchased compared to the cost of used trucks that were sold over the past 12 months, as well as the growth in company trucks. In addition, the purchase of new trailers over the past 12 months to replace older used trailers which were fully depreciated also contributed to the increase in depreciation expense.

Rent and purchased transportation expense decreased $1.2 million or 0.5% in the first six months of 2015 compared to the same 2014 period and did not change as a percentage of operating revenues. Rent and purchased transportation for the Truckload segment decreased $8.1 million in first six months of 2015 compared to the same 2014 period. This decrease is due primarily to lower fuel prices that resulted in lower reimbursements to independent contractors for fuel and lower independent contractor miles in the first six months of 2015 compared to the same period in 2014, offset partially by a higher average settlement rate per mile. VAS rent and purchased transportation expense increased $5.6 million and as a percentage of VAS revenues decreased to 85.1% in the 2015 period from the 86.1% in the 2014 period. The VAS gross margin percentage improved because of our on-going efforts to address customer pricing, contractual and operational issues with VAS.

Communication and utilities increased $0.6 million or 8.8% in the first six months of 2015 compared to the same 2014 period and did not change as a percentage of operating revenues. This increase is primarily due to higher communication costs in the 2015 year-to-date period compared to the 2014 year-to-date period.

Other operating expenses decreased $1.0 million in the first six months of 2015 compared to the same period in 2014 and decreased 0.1% as a percentage of operating revenues. Gains on sales of assets (primarily used trucks and trailers) increased to $12.2 million in the six months ended June 30, 2015 from $9.8 million in the six months ended June 30, 2014. In the 2015 year-to-date period, we sold more trucks and trailers and realized higher average gains per truck and trailer sold. The 2014 year-to-date period also included a $1.6 million gain from the sale of real estate.

Other Expense (Income)

Other expense (income) increased $1.1 million in the first six months of 2015 compared to the same 2014 period and increased 0.1% as a percentage of operating revenues. Interest expense was higher in the first six months of 2015 compared to first six months of 2014 because we had a higher amount of average debt outstanding. We entered into an interest rate swap agreement in September 2014 that effectively fixed our interest rate at 2.5% for five years on debt of $75 million.

Income Taxes

Our effective income tax rate (income taxes expressed as a percentage of income before income taxes) decreased to 39.2% for the first six months of 2015 from 40.25% for the first six months of 2014. The lower income tax rate for the first six months of 2015 is attributed to lower projected non-deductible expenses and lower state income taxes, as well as certain state income tax refunds for prior periods.

Liquidity and Capital Resources:

During the six months ended June 30, 2015, we generated cash flow from operations of $193.6 million, a 114% increase ($103.0 million) in cash flows compared to the same six-month period a year ago. The increase in net cash provided by operating activities resulted primarily from a $66.2 million increase from general working capital activities (including $37.6 million related to accounts receivable due to the timing of customer payments and a $24.7 million decrease in income tax payments due primarily to an overpayment of income taxes as of December 31, 2014) and a $15.0 million increase in net income. We were able to make net capital expenditures and pay dividends with the net cash provided by operating activities and existing cash balances.

Net cash used in investing activities increased to $152.2 million for the six-month period ended June 30, 2015 from $58.1 million for the six-month period ended June 30, 2014. Net property additions (primarily revenue equipment) were $159.4 million for the six-month period ended June 30, 2015, compared to $62.8 million during the same period of 2014. This increase occurred as we continued to lower the average age of our company truck fleet during 2015. As of June 30, 2015, we were committed to property and equipment purchases of approximately $172.5 million. We currently estimate net capital expenditures (primarily revenue equipment) in 2015 to be in the range of $300 million to $325 million, compared to net capital expenditures in 2014 of $212.3 million. We expect the higher capital expenditures in 2015 will enable us to further reduce the average age of our company truck fleet to under two years. We intend to fund these net capital expenditures through cash flow from operations and financing available under our existing credit facilities, as management deems necessary.

22

Net financing activities used $16.2 million during the six months ended June 30, 2015, and $28.5 million during the same period in 2014. During the six-month periods ended June 30, 2015 and 2014, we did not borrow or repay debt, and we made a $3.1 million note payment during the 2015 period. Our outstanding debt at June 30, 2015, was $75.0 million. We paid dividends of $7.2 million in the six-month period ended June 30, 2015 and $7.3 million in the six-month period ended June 30, 2014. Financing activities for the six months ended June 30, 2015, also included common stock repurchases of 225,000 shares at a cost of $6.4 million compared to 1,000,000 shares at a cost of $25.6 million in the 2014 period. From time to time, the Company has repurchased, and may continue to repurchase, shares of the Company’s common stock. The timing and amount of such purchases depend upon stock market conditions and other factors. As of June 30, 2015, the Company had purchased 3,287,291 shares pursuant to our current Board of Directors repurchase authorization and had 4,712,709 shares remaining available for repurchase.

Management believes our financial position at June 30, 2015 is strong. As of June 30, 2015, we had $47.5 million of cash and cash equivalents and $878.2 million of stockholders’ equity. Cash is invested primarily in government portfolio money market funds. As of June 30, 2015, we had a total of $325.0 million of credit pursuant to two credit facilities (see Note 1 in the Notes to Consolidated Financial Statements under Item 1 of Part I of this Form 10-Q for information regarding our credit agreements as of June 30, 2015, as well as changes made subsequent to the end of the period), of which we had borrowed $75.0 million. The remaining $250.0 million of credit available under these facilities is reduced by the $32.7 million in stand-by letters of credit under which we are obligated. These stand-by letters of credit are primarily required as security for insurance policies. Based on our strong financial position, management does not foresee any significant barriers to obtaining sufficient financing, if necessary.

Contractual Obligations and Commercial Commitments:

The following tables set forth our contractual obligations and commercial commitments as of June 30, 2015.

Payments Due by Period

(Amounts in millions)	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years		Period Unknown

As of June 30, 2015, we had unsecured committed credit facilities with two banks as well as a term commitment with one of those banks. In July 2015, we added a credit facility with a third bank, U.S. Bank N.A., and amended our prior agreement with Wells Fargo Bank, N.A. We now have with Wells Fargo Bank, N.A. a $100 million credit facility which will expire on July 12, 2020 (prior to the recent amendment, it was a $175 million facility expiring May 31, 2016) and a $75 million term commitment with principal due and payable on September 15, 2019. We added in July a $75 million credit facility with U.S. Bank N.A. which will expire on July 13, 2020. We also have a $75 million credit facility with BMO Harris Bank, N.A. which will expire on March 5, 2020. Borrowings under the credit facilities and term note bear variable interest (0.7855% at June 30, 2015) based on the London Interbank Offered Rate (“LIBOR”), with interest on the term note effectively fixed at 2.5% with an interest rate swap agreement. Interest payments on debt are based on the debt balance and interest rate at June 30, 2015. The credit available under these facilities is further reduced by the amount of stand-by letters of credit under which we are obligated. The stand-by letters of credit are primarily required for insurance policies. The unused lines of credit are available to us in the event we need financing for the replacement of our fleet or for other significant capital expenditures. Management believes our financial position is strong, and we therefore expect that we could obtain additional financing, if necessary. Property and equipment purchase commitments relate to committed equipment expenditures, primarily for revenue equipment. As of June 30, 2015, we had recorded an $9.1 million liability for unrecognized tax benefits. We expect none of it to be settled within the next twelve months and are unable to reasonably determine when the $9.1 million categorized as “period unknown” will be settled.

Off-Balance Sheet Arrangements:

We began leasing certain tractors under non-cancelable operating leases in May 2011, and those leases ended in second quarter 2015.

Regulations:

Item 1 of Part I of our 2014 Form 10-K includes a discussion of pending proposed regulations that may have an effect on our operations if they become adopted and effective as proposed. There have been no material changes in the status of these proposed regulations previously disclosed in the 2014 Form 10-K.

Critical Accounting Policies and Estimates:

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the (i) reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and (ii) reported amounts of revenues and expenses during the reporting period. We evaluate these estimates on an ongoing basis as events and circumstances change, utilizing historical experience, consultation with experts and other methods considered reasonable in the particular circumstances. Actual results could differ from those estimates and may significantly impact our results of operations from period to period. It is also possible that materially different amounts would be reported if we used different estimates or assumptions.

Information regarding our Critical Accounting Policies and Estimates can be found in our 2014 Form 10-K. The most critical accounting policies and estimates that require us to make significant judgments and estimates and affect our financial statements include the following:

• Depreciation and impairment of tractors and trailers.

• Estimates of accrued liabilities for insurance and claims for liability and physical damage losses and workers’ compensation.

• Accounting for income taxes.

There have been no material changes to these critical accounting policies and estimates from those discussed in our 2014 Form 10-K.

Accounting Standards:

In the descriptions under “New Accounting Pronouncements Adopted” and “Accounting Standards Updates Not Yet Effective” that follow, references in quotations identify guidance and Accounting Standards Updates (“ASU”) relating to the topics and subtopics (and their descriptive titles, as appropriate) of the Accounting Standards Codification^™ of the Financial Accounting Standards Board (“FASB”).

New Accounting Pronouncements Adopted

We did not adopt any new accounting standards during second quarter 2015.

Accounting Standards Updates Not Yet Effective

On May 28, 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In July 2015, the FASB voted to approve a one-year deferral of the effective date of the new revenue recognition standard and to permit early adoption but no earlier than the original effective date (annual periods beginning after December 15, 2016). As a result of the deferral, the new standard will become effective for us beginning January 1, 2018, unless we choose to adopt early on January 1, 2017. The standard permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures and have not yet selected a transition method.

In April 2015, the FASB issued ASU No. 2015-3, "Interest - Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs," which requires debt issuance costs to be recorded as a direct reduction of the debt liability on the balance sheet rather than as an asset. The provisions of this update are effective as of January 1, 2016, and are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

In July 2015, the FASB issued ASU No. 2015-11, "Inventory: Simplifying the Measurement of Inventory," which requires inventory to be recorded at the lower of cost and net realizable value. The provisions of this update are effective as of January 1, 2017, and are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

Other ASUs not effective until after June 30, 2015 are not expected to have a material effect on our consolidated financial position, results of operations or cash flows.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are exposed to market risk from changes in commodity prices, foreign currency exchange rates and interest rates.

Commodity Price Risk

The price and availability of diesel fuel are subject to fluctuations attributed to changes in the level of global oil production, refining capacity, seasonality, weather and other market factors. Historically, we have recovered a majority, but not all, of fuel price increases from customers in the form of fuel surcharges. We implemented customer fuel surcharge programs with most of our customers to offset much of the higher fuel cost per gallon. However, we do not recover all of the fuel cost increase through these surcharge programs. We cannot predict the extent to which fuel prices will increase or decrease in the future or the extent to which fuel surcharges could be collected. As of June 30, 2015, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.

Foreign Currency Exchange Rate Risk

We conduct business in several foreign countries, including Mexico, Canada, China and Australia. To date, most foreign revenues are denominated in U.S. Dollars, and we receive payment for foreign freight services primarily in U.S. Dollars to reduce direct foreign currency risk. Assets and liabilities maintained by a foreign subsidiary company in the local currency are subject to foreign exchange gains or losses. Foreign currency translation gains and losses primarily relate to changes in the value of revenue equipment owned by a subsidiary in Mexico, whose functional currency is the Peso. Foreign currency translation losses were $698 thousand for second quarter 2015 and foreign currency translation gains were $90 thousand for second quarter 2014 and were recorded in accumulated other comprehensive loss within stockholders’ equity in the Consolidated Balance Sheets.

Interest Rate Risk

We manage interest rate exposure through a mix of variable rate debt and interest rate swap agreements.We had $75.0 million of debt outstanding at June 30, 2015, for which the interest rate is effectively fixed at 2.5% through September 2019 with an interest rate swap agreement. Interest rates on our unused credit facilities are based on the LIBOR. Increases in interest rates could impact our annual interest expense on future borrowings. As of June 30, 2015, we had one effective interest rate swap agreement with a notional amount of $75.0 million to reduce our exposure to interest rate increases.

Item 4. Controls and Procedures.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rule 15d-15(e) of the Securities Exchange Act of 1934 (the “Exchange Act”). Our disclosure controls and procedures are designed to provide reasonable assurance of achieving the desired control objectives. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective at a reasonable assurance level in enabling us to record, process, summarize and report information required to be included in our periodic filings with the SEC within the required time period and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, concluded that no changes in our internal control over financial reporting occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We have confidence in our internal controls and procedures. Nevertheless, our management, including the Chief Executive Officer and Chief Financial Officer, does not expect that the internal controls or disclosure procedures and controls will prevent all errors or intentional fraud. An internal control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of such internal controls are met. Further, the design of an internal control system must reflect that resource constraints exist, and the benefits of controls must be evaluated relative to their costs. Because of the inherent limitations in all internal control systems, no evaluation of controls can provide absolute assurance that all control issues, misstatements and instances of fraud, if any, have been prevented or detected.

OTHER INFORMATION

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On October 15, 2007, we announced that on October 11, 2007 our Board of Directors approved an increase in the number of shares of our common stock that the Company is authorized to repurchase. Under this authorization, the Company is permitted to repurchase an additional 8,000,000 shares. As of June 30, 2015, the Company had purchased 3,287,291 shares pursuant to this authorization and had 4,712,709 shares remaining available for repurchase. The Company may purchase shares from time to time depending on market, economic and other factors. The authorization will continue unless withdrawn by the Board of Directors.

The following table summarizes our common stock repurchases during the second quarter of 2015 made pursuant to this authorization. The Company did not purchase any shares during the second quarter of 2015 other than pursuant to this authorization. All stock repurchases were made by the Company or on its behalf and not by any “affiliated purchaser,” as defined by Rule 10b-18 of the Exchange Act.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

For the three-month and six-month periods ended June 30, 2015, there were no material changes to the total amount of unrecognized tax benefits. We accrued interest expense of $65 thousand and $64 thousand during the three-month periods ended June 30, 2015 and June 30, 2014, respectively, and $124 thousand and $122 thousand during the six-month periods ended June 30, 2015, and June 30, 2014, respectively, excluding the reversal of accrued interest related to adjustments for the remeasurement of uncertain tax positions. Our total gross liability for unrecognized tax benefits at June 30, 2015, is $9.1 million. If recognized, $5.8 million of unrecognized tax benefits would impact our effective tax rate. Interest of $1.8 million has been reflected as a component of the total liability. We expect no other significant increases or decreases for uncertain tax positions during the next twelve months.

We file U.S. federal income tax returns, as well as income tax returns in various states and several foreign jurisdictions. The years 2011 through 2014 are open for examination by the Internal Revenue Service (“IRS”), and various years are open for examination by state and foreign tax authorities. State and foreign jurisdictional statutes of limitations generally range from three to four years.

Credit Facilities

As of June 30, 2015, we had unsecured committed credit facilities with two banks as well as a term commitment with one of these banks. We had with Wells Fargo Bank, N.A., a $175.0 million credit facility which was set to expire on May 31, 2016, and a $75.0 million term commitment with principal due and payable on September 15, 2019. We also had a $75.0 million credit facility with BMO Harris Bank N.A., which will expire on March 5, 2020. Borrowings under these credit facilities and term note bear variable interest (0.7855% at June 30, 2015) based on the London Interbank Offered Rate (“LIBOR”), with interest on the term note effectively fixed at 2.5% with an interest rate swap agreement.

On July 13, 2015, we amended our existing credit agreement, dated June 1, 2012, as previously amended, with Wells Fargo Bank, N.A. This amendment lowered the maximum principal amount of the unsecured line of credit to $100.0 million from $175.0 million and extended the term of the credit agreement to July 12, 2020 from May 31, 2016. Also on July 13, 2015, we entered into a new credit agreement with U.S. Bank N.A. The new credit agreement is an unsecured line of credit of $75.0 million and expires on July 13, 2020.

As of June 30, 2015, and December 31, 2014, our outstanding debt totaled $75.0 million. The $325.0 million of credit available under these facilities at June 30, 2015, is further reduced by $32.7 million in stand-by letters of credit under which we are obligated. Each of the debt agreements in effect at June 30, 2015 includes, among other things, two financial covenants requiring us (i) not to exceed a maximum ratio of total debt to total capitalization and (ii) not to exceed a maximum ratio of total funded debt to earnings before interest, income taxes, depreciation and amortization (as such terms are defined in each credit facility). At June 30, 2015, we were in compliance with these covenants.

At June 30, 2015, the aggregate future maturities of long-term debt by year are as follows (in thousands):

2015	$	—
2016	—
2017	—
2018	—
2019	75,000
Total	$	75,000

The carrying amounts of our long-term debt approximate fair value due to the duration of the notes and the variable interest rates.

Segment Reporting [Abstract]

Segment Information

Segment Information

We have two reportable segments – Truckload Transportation Services (“Truckload”) and Value Added Services (“VAS”).

The Truckload segment consists of two operating units, One-Way Truckload and Specialized Services, that are aggregated because they have similar economic characteristics and meet the other aggregation criteria described in the accounting guidance for segment reporting. One-Way Truckload is comprised of the following operating fleets: (i) the regional short-haul (“Regional”) fleet transports a variety of consumer nondurable products and other commodities in truckload quantities within geographic regions across the United States using dry van trailers; (ii) the medium-to-long-haul van (“Van”) fleet provides comparable truckload van service over irregular routes; and (iii) the expedited (“Expedited”) fleet provides time-sensitive truckload services utilizing driver teams. Specialized Services provides truckload services dedicated to a specific customer, generally for a retail distribution center or manufacturing facility, including services for products requiring specialized trailers such as flatbed or temperature-controlled trailers. Revenues for the Truckload segment include a small amount of non-trucking revenues which consist primarily of the portion of shipments delivered to or from Mexico where we utilize a third-party capacity provider.

The VAS segment generates the majority of our non-trucking revenues through four operating units that provide non-trucking services to our customers. These four VAS operating units are as follows: (i) truck brokerage (“Brokerage”) uses contracted carriers to complete customer shipments; (ii) freight management (“Freight Management”) offers a full range of single-source logistics management services and solutions; (iii) the intermodal (“Intermodal”) unit offers rail transportation through alliances with rail and drayage providers as an alternative to truck transportation; and (iv) Werner Global Logistics international (“WGL”) provides complete management of global shipments from origin to destination using a combination of air, ocean, truck and rail transportation modes.

We generate other revenues from transportation-related activities such as third-party equipment maintenance and equipment leasing and other business activities. None of these operations meets the quantitative reporting thresholds. As a result, these operations are grouped in “Other” in the table below. “Corporate” includes revenues and expenses that are incidental to our activities and are not attributable to any of our operating segments. We do not prepare separate balance sheets by segment and, as a result, assets are not separately identifiable by segment. Inter-segment eliminations in the table below represent transactions between reporting segments that are eliminated in consolidation.

Equity Compensation [Abstract]

Equity Compensation

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 June 30, 2015, there were 7,183,373 shares available for granting additional awards.

Equity compensation expense is included in salaries, wages and benefits within the Consolidated Statements of Income. As of June 30, 2015, the total unrecognized compensation cost related to non-vested equity compensation awards was approximately $12.5 million and is expected to be recognized over a weighted average period of 2.5 years.

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

	Three Months Ended June 30,				Six Months Ended June 30,

Tax benefit	377		174		675		289
Performance award expense, net of tax	$	576	$	257	$	1,033	$	428

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 six months ended June 30, 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	(44	)	17.44
Forfeited	(5	)	20.33
Expired	—		—
Outstanding at end of period	199		18.28		3.45	$	1,587
Exercisable at end of period	157		17.78		3.00	$	1,332

We did not grant any stock options during the three-month and six-month periods ended June 30, 2015 and June 30, 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 $1.9 million for the six-month periods ended June 30, 2015 and June 30, 2014.

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 six months ended June 30, 2015:

	Number of Restricted Awards (in thousands)		Weighted Average Grant Date Fair Value ($)
Nonvested at beginning of period	643		$	22.92
Granted	—		—
Vested	(2	)	24.21
Forfeited	(17	)	24.07
Nonvested at end of period	624		22.88

We did not grant any restricted awards during the three-month and six-month periods ended June 30, 2015 and granted 10,000 shares of restricted stock during the three-month and six-month periods ended June 30, 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. The present value of estimated future dividends for the 2014 grants was calculated using the following weighted-average assumptions:

Dividends per share (quarterly amounts)	$	0.05
Risk-free interest rate	1.5		%

The total fair value of previously granted restricted awards vested during the three-month and six-month periods ended June 30, 2015 was $70 thousand and for the three-month and six-month periods ended June 30, 2014 was $90 thousand. 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 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 six months ended June 30, 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 did not grant any performance awards during the three-month periods ended June 30, 2015 and June 30, 2014, respectively, and granted performance awards (in thousands) totaling 202 shares and 183 shares during the six-month periods ended June 30, 2015 and June 30, 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:

	Six Months Ended June 30,
	2015			2014
Dividends per share (quarterly amounts)	$	0.05		$	0.05
Risk-free interest rate	1.6		%	1.5		%

During the six-month period ended June 30, 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 six-month period ended June 30, 2015 was $1.1 million. 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 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instrument

Derivative Financial Instrument

In the normal course of business we are subject to risk from adverse fluctuations in foreign exchange and interest rates and commodity prices. We manage our risks for interest rate changes through use of an interest rate swap. At June 30, 2015, we had one interest rate swap outstanding, which matures in September 2019, with a notional value of $75.0 million and a fair value loss of $1.5 million. The counterparty to this contract is a major financial institution. We are exposed to credit loss in the event of non-performance by the counterparty. We do not use derivative instruments for trading or speculative purposes and have no derivative financial instruments to reduce our exposure to fuel price fluctuations.

Our objective in managing exposure to interest rate risk is to limit the impact on earnings and cash flow. The extent to which we use such instruments is dependent on our access to these contracts in the financial markets and our success using other methods.

Our outstanding derivative financial instrument is recognized as an other long-term liability in the Consolidated Balance Sheets at fair value. The interest rate swap is accounted for as a cash flow hedging instrument. At inception, we formally designated and documented the financial instrument as a hedge of a specific underlying exposure, the risk management objective, and the manner in which effectiveness of the hedge will be assessed. We formally assess, both at inception and at each reporting period thereafter, whether the derivative financial instrument is effective in offsetting changes in cash flows of the related underlying exposure. All changes in fair value of outstanding derivatives in cash flow hedges, except any ineffective portion, are recorded in other comprehensive income until earnings are impacted by the hedged transaction. Classification of the gain or loss in the Consolidated Statements of Income upon release from comprehensive income is the same as that of the underlying exposure. Any ineffective portion of the change in fair value of the instruments is recognized immediately in earnings.

We will discontinue the use of hedge accounting prospectively when (i) the derivative instrument is no longer effective in offsetting changes in fair value or cash flows of the underlying hedged item; (ii) the derivative instrument expires, is sold, terminated or exercised; or (iii) designating the derivative instrument as a hedge is no longer appropriate.

Should we discontinue hedge accounting because it is no longer probable that an anticipated transaction will occur in the originally expected period, or within an additional two-month period thereafter, changes to fair value accumulated in other comprehensive income would be recognized immediately in earnings.

FASB ASC 815-10 requires companies to recognize the derivative instrument as an asset or a liability at fair value in the statement of financial position. Fair value of the derivative instrument is required to be measured under the FASB’s Fair Value Measurements and Disclosures guidance, which establishes a hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). Level 1 inputs use quoted prices (unadjusted) in active markets for identical assets or liabilities that we have the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. The fair value of our interest rate swap is based on Level 2 inputs.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of common shares outstanding plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options and restricted stock awards. There are no differences in the numerators of our computations of basic and diluted earnings per share for any period presented.

The computation of basic and diluted earnings per share is shown below (in thousands, except per share amounts).

	Three Months Ended June 30,				Six Months Ended June 30,
	2015		2014		2015		2014
Net income	$	31,848	$	25,632	$	54,990	$	39,971
Weighted average common shares outstanding	71,945		72,091		72,005		72,382
Dilutive effect of stock-based awards	479		506		477		500
Shares used in computing diluted earnings per share	72,424		72,597		72,482		72,882
Basic earnings per share	$	0.44	$	0.36	$	0.76	$	0.55
Diluted earnings per share	$	0.44	$	0.35	$	0.76	$	0.55

There were no options to purchase shares of common stock that were outstanding during the periods indicated above that were excluded from the computation of diluted earnings per share because the option purchase price was greater than the average market price of the common shares during the period. Performance awards are excluded from the calculation of dilutive potential common shares until the threshold performance conditions have been satisfied.
