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




• COVID-19


• Results of Operations


• Liquidity and Capital Resources

• Contractual Obligations and Commercial Commitments

• Regulations

• Critical Accounting Estimates

The MD&A should be read in conjunction with our 2019 Form 10-K.

Overview:

We have two reportable segments, Truckload Transportation Services ("TTS") and Werner Logistics, 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 TTS segment) or obtain qualified third-party capacity at a reasonable price (with respect to our Werner Logistics segment). Although our business volume is not highly concentrated, we may also be affected by our customers' financial failures or loss of customer business.

Revenues for our TTS segment operating units (Dedicated and One-Way Truckload) 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 surcharge revenues 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 TTS segment also generates a small amount of revenues categorized as non-trucking revenues, which consist primarily of the intra-Mexico portion of cross-border shipments delivered to or from Mexico where the TTS 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 TTS 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 TTS 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 first quarter 2020 to first quarter 2019, 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, compliance with new or proposed regulations and a weakening used equipment market. Our main fixed costs include depreciation expense for tractors and trailers and equipment licensing fees (included in taxes and licenses expense). The TTS segment requires substantial cash 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 Werner Logistics segment (Truckload Logistics, Intermodal, WGL and Final Mile). Unlike our TTS segment, the Werner Logistics 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 Werner Logistics 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 Werner Logistics 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.

COVID-19:

The COVID-19 pandemic, declared March 11, 2020, has profoundly impacted the U.S. economy. During the pandemic, the transportation industry has been designated by the U.S. government as an essential industry for keeping the U.S. supply chain moving. We are working hard to stay healthy while safely delivering our customers' freight on time. Our leadership team meets daily to address issues related to customers, freight, drivers, safety, staffing, human resources, and costs, and provides regular updates to all our associates. Throughout our offices and terminal network, we are closely following the safety guidelines set forth by the Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO), including hygiene and distancing. We have already made significant investments in personal protective products to keep our associates safe, and over half of our office associates are working from home. We introduced Werner-specific associate relief plans to provide rapid and needed assistance to those Werner associates affected by the virus.

Over the past several years, we have repositioned Werner to increase our ability to execute through different macroeconomic environments. We believe our freight base, which is heavily weighted toward customers delivering essential products that are continually being restocked in today's economy, will enable us to more effectively manage through the difficult economic environment created by the pandemic. Our results for first quarter 2020 reflect freight demand that was slightly below the same period a year ago, with above normal demand the last two to three weeks of March as consumers purchased essential products for their homes. 62% of first quarter 2020 revenues from our top 100 customers (85% of revenues in first quarter 2020) came from the discount retail, home improvement retail, food and beverage, and consumer packaged goods verticals.

Our second quarter and 2020 results will likely be further impacted by the disruptive effect of COVID-19, although the degree of disruption is difficult to predict. Freight demand in our One-Way Truckload unit in April 2020 was lower than April 2019, with some expected gradual freight softening, and Dedicated volumes have been mostly steady. We are, however, preparing for various scenarios that could result in an extremely challenging second quarter. We do not plan to grow our truck fleet until market conditions improve, and our fleet count may decline more in second quarter 2020 depending on the freight market and the pace and timing of recovery. We are addressing discretionary controllable costs wherever possible, including voluntary pay reductions for all members of the executive team and implementing hiring freezes for nearly all non-driver open positions. We performed a customer industry and financial risk assessment on our 100 largest customers shortly after the pandemic declaration. While our financial risk has clearly increased since the pandemic began, we believe we have a relatively lower level of financial risk with the predominance of financially stronger companies in our customer base as well as a lower overall industry risk due to our focus on industries delivering essential products.

At the end of first quarter 2020, we believe we are well positioned with a strong balance sheet and sufficient liquidity. Our debt is low at $250 million, or net debt ratio of 0.4 times EBITDA, and we paid off $50 million of debt in first quarter. We had available liquidity of $352 million, considering cash on hand and available credit facilities of $280.4 million, and also have sufficient cushion with our two debt covenants. For our $75 million credit facility that will expire on July 13, 2020, we currently intend to pay the outstanding balance in full, on or before the maturity date, using long-term financing under our other existing credit facilities. We currently do not intend to repurchase shares of stock until there is more clarity on the duration and effects of COVID-19. We do, however, currently plan to continue paying our quarterly dividend, which we have paid for 34 consecutive years. This capital outlay currently results in slightly more than $6 million per quarter. 2020 net capital expenditures currently are expected to be in the range of $260 million to $300 million. This includes an estimated $46 million decrease in new truck purchases offset by an estimated lower number of used truck sales at lower expected prices amounting to $42 million. We continue to expect free cash flow (net cash provided by operating activities less net cash used for capital expenditures) to exceed $100 million in 2020.

We don't currently expect the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act"), enacted in March 2020, to have a material impact on our consolidated financial statements. Under the CARES Act, we currently intend to defer payment of certain employer payroll taxes for the remainder of 2020, with 50% due December 31, 2021 and 50% due December 31, 2022. We also expect to utilize a provision allowing accelerated income tax depreciation for certain assets, which will not impact our effective tax rate. There have been a number of regulatory actions and waivers related to the COVID-19 pandemic, in an effort to keep the supply chain moving. We do not expect these collective changes to have a material impact on our consolidated financial statements.

Three Months Ended March 31, 2020 Compared to Three Months Ended March 31, 2019 Operating Revenues Operating revenues decreased 0.6% for the three months ended March 31, 2020, compared to the same period of the prior year. When comparing first quarter 2020 to first quarter 2019, TTS segment revenues increased $2.0 million, or 0.4%, and Werner Logistics revenues decreased $5.2 million, or 4.4%.

During first quarter 2020, freight demand in our One-Way Truckload fleet in January and February was seasonally normal and slightly below the same period a year ago. Following the pandemic declaration on March 11, we experienced strengthening demand for the last two to three weeks of March. This led to demand for the full month of March 2020 being comparable to March 2019. In our Dedicated fleet, freight demand remained steady in first quarter 2020 with above normal demand in March for store replenishment, primarily due to customer inventory restocking following consumers buying essential products for their households after the pandemic declaration.

April 2020 freight demand was lower than April 2019, with some expected gradual weakening as a result of many parts of the U.S. economy being shut down or significantly curtailed. Our freight base is designed to more effectively manage through what we anticipate will be an extremely difficult economic environment in second quarter 2020, as a significant portion of our revenues come from delivering essential goods and products. 62% of revenues from our top 100 customers (85% of revenues in first quarter 2020) came from the discount retail, home improvement retail, food and beverage or consumer packaged goods industry groups.

Trucking revenues, net of fuel surcharge, increased 2.9% in first quarter 2020 compared to first quarter 2019 due to a 3.2% increase in average revenues per tractor per week, net of fuel surcharge, which was due primarily to an increase in average miles per tractor and to a lesser extent an increase in average revenues per total mile, partially offset by a 0.3% decrease in the average number of tractors in service. The increase in average revenues per total mile was due primarily to relative strength in Dedicated pricing, mostly offset by a 3.7% decrease in One-Way Truckload pricing. We currently expect average revenues per total mile for the One-Way Truckload fleet for the first half of 2020 to decrease in a range of 5% to 7% when compared to the first half of 2019, resulting from what we believe will be a very difficult freight market in May and June 2020.

The average number of tractors in service in the TTS segment decreased 0.3% to 7,862 in first quarter 2020 from 7,887 in first quarter 2019. We ended first quarter 2020 with 7,835 trucks in the TTS segment, a year-over-year decrease of 110 trucks compared to the end of first quarter 2019, and a sequential decrease of 165 trucks compared to the end of fourth quarter 2019. We currently expect our truck count at the end of 2020 to be in a range of 5% lower to flat when compared to the fleet size at year-end 2019. Our fleet count may decline more in second quarter depending on the freight market and the pace and timing of recovery. We cannot predict whether future driver shortages, if any, will adversely affect our ability to maintain our fleet size. If such a driver 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 decreased 12.3% to $51.0 million in first quarter 2020 from $58.2 million in first quarter 2019 due to lower average fuel prices in the 2020 quarter. These 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. 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.

Werner Logistics revenues are generated by its four operating units and exclude revenues for full truckload shipments transferred to the TTS segment, which are recorded as trucking revenues by the TTS segment. Werner Logistics also recorded revenue and brokered freight expense of $11 thousand in first quarter 2020 and $205 thousand in first quarter 2019 for Intermodal drayage movements performed by the TTS segment (also recorded as trucking revenue by the TTS segment), and these transactions between reporting segments are eliminated in consolidation. In first quarter 2020, Werner Logistics revenues decreased $5.2 million, or 4.4%, primarily due to lower Truckload Logistics revenues as a result of fewer transactional freight opportunities from a slowing freight economy and the competitive logistics market. However, due to an 8% increase in contractual shipments, our Truckload Logistics total load count increased 1% while revenue per load declined 10%. Intermodal revenues decreased 6%. The Werner Logistics gross margin percentage in first quarter 2020 of 14.5% decreased from 17.3% in first quarter 2019 due primarily to a softer freight market, and contractual brokerage had a higher cost of capacity in March 2020 due to higher store replenishment activity. The Werner Logistics operating income percentage in first quarter 2020 of 1.0% decreased from 4.0% in first quarter 2019 as the percentage decline in gross profit exceeded the percentage decline in other operating expenses. Other operating expenses in first quarter 2020 included $0.5 million of bad debt expense primarily due to customer bankruptcies.

Operating Expenses Our operating ratio (operating expenses expressed as a percentage of operating revenues) was 94.8% for the three months ended March 31, 2020, compared to 91.9% for the three months ended March 31, 2019. Expense items that impacted the overall operating ratio are described on the following pages. The tables on pages 20 through 22 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, TTS and Werner Logistics.

Salaries, wages and benefits increased $3.2 million or 1.6% in first quarter 2020 compared to first quarter 2019 and increased 0.8% as a percentage of operating revenues to 34.8%. The higher dollar amount of salaries, wages and benefits expense in the 2020 first quarter was due primarily to higher driver pay rates and approximately 6.4 million more company truck miles, both of which also resulted in higher payroll taxes and other payroll-related fringe benefits. Non-driver salaries, wages and benefits in the non-trucking Werner Logistics segment decreased 9.3%.

We renewed our workers' compensation insurance coverage on April 1, 2020 and took on additional risk exposure by increasing our self-insurance retention from $1.0 million to $2.0 million per claim as of April 1, 2020. As a result of the higher self-insured retention, our workers' compensation insurance premiums for the policy year beginning April 2020 are $0.8 million lower than the premiums for the previous policy year.

The driver recruiting market is extremely competitive. Several ongoing market factors persisted including a declining number of, and increased competition for, driver training school graduates, aging truck driver demographics and increased truck safety regulations including the regulation changes for electronic logging devices. We continue to take significant actions to strengthen our driver recruiting and retention to make Werner a preferred choice for the best drivers, including raising driver pay, maintaining a new truck and trailer fleet, purchasing best-in-class safety features for all new trucks, investing in our driver training school network and collaborating with customers to improve or eliminate unproductive freight. These efforts continue to have positive results on our driver retention. We are unable to predict whether we will experience future driver shortages or continue to maintain our current driver retention rates. If such a driver 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 $7.4 million or 13.1% in first quarter 2020 compared to first quarter 2019 and decreased 1.2% as a percentage of operating revenues due to lower average diesel fuel prices, despite approximately 6.4 million more company truck miles in first quarter 2020. Average diesel fuel prices were 34 cents per gallon lower in first quarter 2020 than in first quarter 2019 and were 41 cents per gallon lower than in fourth quarter 2019.

We continue to employ measures to improve our fuel 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, 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 partially offset by higher depreciation expense and the additional cost of diesel exhaust fluid. 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 April 2020, the average diesel fuel price per gallon was approximately $1.22 lower than the average diesel fuel price per gallon in April 2019 and approximately $1.14 lower than in second quarter 2019.

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 March 31, 2020, we had no derivative financial instruments to reduce our exposure to fuel price fluctuations.

Supplies and maintenance remained flat in first quarter 2020 compared to first quarter 2019. The increased expense resulting from higher company truck miles in 2020 was offset by lower driver recruiting and other driver-related costs, as well as lower non-driver travel expenses.

Insurance and claims increased $13.4 million or 58.8% in first quarter 2020 compared to first quarter 2019 and increased 2.3% as a percentage of operating revenues due primarily to higher expense for new large dollar claims. In January 2020, one of our trucks was involved in a serious accident. We self-insure for the first $10.0 million of liability coverage for this policy period and have appropriate excess liability insurance coverage with insurance carriers above this amount. As a result, we accrued $10.0 million of insurance and claims expense in first quarter 2020 for this accident. We also incurred insurance claims expense of $1.2 million in both first quarter 2020 and first quarter 2019 for accrued interest related to a previously-disclosed adverse jury verdict rendered May 17, 2018, which we are appealing (see Note 5 in the Notes to Consolidated Financial Statements (Unaudited) set forth in Part 1 of this report). Interest is accrued at $0.4 million per month, until such time as the outcome of our appeal is finalized. 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, 2019 with the same deductibles and aggregates as the August 1, 2018 renewal. We continue to be responsible for the first $3.0 million per claim with an annual $6.0 million aggregate for claims between $3.0 million and $5.0 million. We also have an additional $5.0 million deductible per claim for each claim between $5.0 million and $10.0 million. As a result, we are responsible for the first $10.0 million per claim, until we meet the $6.0 million aggregate for claims between $3.0 million and $5.0 million. We maintain liability insurance coverage with insurance carriers substantially in excess of the $10.0 million per claim. Our liability insurance premiums for the policy year that began August 1, 2019 are 11% higher, or $0.7 million higher, than premiums for the previous policy year.

Depreciation expense increased $8.1 million or 13.3% in first quarter 2020 compared to first quarter 2019 and increased 1.4% as a percentage of operating revenues. During first quarter 2020, we changed the estimated life of certain trucks currently expected to be sold in 2020 to more rapidly depreciate these truck to their estimated residual values due to the weak used truck market. The effect of this change in accounting estimate increased first quarter depreciation expense by $5.0 million. These trucks will continue to depreciate at the same higher rate per truck until the trucks are sold. Information technology and communications infrastructure upgrades also added to the higher depreciation expense in first quarter 2020.

The average age of our truck fleet remains low by industry standards and was 2.0 years as of March 31, 2020, and the average age of our trailers was 4.1 years. We are continuing to invest in new trucks and trailers and our terminals in 2020 to improve our driver experience, increase operational efficiency and more effectively manage our maintenance, safety and fuel costs. During the remainder of 2020, we expect the average age of our truck and trailer fleet to increase slightly from current levels depending on freight recovery from the COVID-19 pandemic and the timing of when equipment manufacturers re-open their truck and trailer manufacturing plants.

Rent and purchased transportation expense decreased $6.4 million or 4.8% in first quarter 2020 compared to first quarter 2019 and decreased 1.0% as a percentage of operating revenues. Rent and purchased transportation expense consists mostly of payments to third-party capacity providers in the Werner Logistics segment and other non-trucking operations and payments to independent contractors in the TTS segment. The payments to third-party capacity providers generally vary depending on changes in the volume of services generated by the Werner Logistics segment. Werner Logistics rent and purchased transportation expense decreased $1.1 million as a result of lower logistics revenues, but as a percentage of Werner Logistics revenues increased to 85.5% in first quarter 2020 from 82.7% in first quarter 2019, due primarily to a softer and more competitive Truckload Logistics freight market.

Rent and purchased transportation expense for the TTS segment decreased $5.6 million in first quarter 2020 compared to first quarter 2019. Independent contractor miles decreased approximately 1.9 million miles in first quarter 2020 and as a percentage of total miles were 8.9% in first quarter 2020 compared to 10.0% in first quarter 2019. The per-mile settlement rate for independent contractors also decreased in first quarter 2020 compared to first quarter 2019, due in part to lower diesel fuel prices. Because independent contractors supply their own tractors and drivers and are responsible for their operating expenses, the decrease in independent contractor miles as a percentage of total miles shifted costs from the rent and purchased transportation category to other expense categories, including (i) salaries, wages and benefits, (ii) fuel, (iii) depreciation, (iv) supplies and maintenance and (v) taxes and licenses.

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. Historically we have 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. These rate increases could negatively affect our results of operations to the extent that we would not be able to obtain corresponding freight rate increases.

Other operating expenses increased $2.9 million in first quarter 2020 compared to first quarter 2019 and increased 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 were $2.5 million in first quarter 2020 compared to $5.9 million in first quarter 2019. We realized significantly lower average gains per truck and trailer in first quarter 2020 compared to first quarter 2019 and sold 44% fewer trucks and 3% fewer trailers. Pricing in the market for our used trucks and trailers continued to weaken in first quarter 2020 due to declining demand.

Other Expense (Income) Other expense (income) increased $1.2 million in first quarter 2020 compared to first quarter 2019. Interest expense increased $0.7 million in first quarter 2020 compared to first quarter 2019 due to higher average outstanding debt in the 2020 quarter.

Income Taxes Our effective income tax rate (income taxes expressed as a percentage of income before income taxes) was 23.3% in first quarter 2020 compared to 25.1% in first quarter 2019. The lower income tax rate in first quarter 2020 was attributed primarily a favorable discrete income tax item in first quarter 2020.

Liquidity and Capital Resources: During the three months ended March 31, 2020, we generated cash flow from operations of $133.4 million, a 3.9% or $5.4 million decrease in cash flows compared to the same three-month period a year ago. The decrease in net cash provided by operating activities resulted primarily from lower net income and decreased cash flows from working capital, partially offset by higher non-cash depreciation. We were able to make net capital expenditures, repay debt, pay dividends and repurchase company stock with the net cash provided by operating activities and existing cash balances.

Net cash used in investing activities decreased to $16.5 million for the three-month period ended March 31, 2020 from $79.9 million for the three-month period ended March 31, 2019. Net property additions (primarily revenue equipment) were $18.8 million for the three-month period ended March 31, 2020, compared to $83.4 million during the same period of 2019, due primarily to delays in receiving new trucks and trailers from our manufacturers. As of March 31, 2020, we were committed to property and equipment purchases of approximately $187.9 million. We currently estimate net capital expenditures (primarily revenue equipment) in 2020 to be in the range of $260 million to $300 million, compared to net capital expenditures in 2019 of $283.9 million. We intend to fund these net capital expenditures through cash flow from operations and financing available under our existing credit facilities, if necessary.

Net financing activities used $69.0 million during the three months ended March 31, 2020, and used $28.1 million during the same period in 2019. We repaid $50.0 million of long-term debt during the three months ended March 31, 2020, bringing our outstanding debt at March 31, 2020 to $250.0 million. We paid dividends of $6.2 million in the three-month period ended March 31, 2020 and $6.3 million in the three-month period ended March 31, 2019. Beginning with the dividend paid in July 2018, we increased our quarterly dividend rate by $0.02 per share, or 29%, to the current rate of $0.09 per share. Financing activities for the three months ended March 31, 2020, also included common stock repurchases of 282,992 shares at a cost of $8.8 million. The Company is temporarily suspending the repurchase of shares of stock under its stock repurchase plan until there is more clarity on the duration and effects of COVID-19. 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 economic and stock market conditions and other factors. As of March 31, 2020, the Company had purchased 982,992 shares pursuant to our current Board of Directors repurchase authorization and had 4,017,008 shares remaining available for repurchase.

Management believes our financial position at March 31, 2020 is strong. As of March 31, 2020, we had $72.2 million of cash and cash equivalents and over $1.1 billion of stockholders' equity. Cash is invested primarily in government portfolio money market funds. As of March 31, 2020, we had a total of $575.0 million of borrowing capacity under three credit facilities (see Note 4 in the Notes to Consolidated Financial Statements (Unaudited) under Item 1 of Part I of this Form 10-Q), of which we had borrowed $250.0 million. For our $75.0 million credit facility that will expire on July 13, 2020, we currently intend to pay the outstanding balance in full, on or before the maturity date, using long-term financing under our other existing credit facilities. The remaining $325.0 million of credit available under these facilities at March 31, 2020 is reduced by the $44.6 million in stand-by letters of credit under which we are obligated, leaving $280.4 million available for future borrowing. These stand-by letters of credit are primarily required as security for insurance policies. We believe our liquid assets, cash generated from operating activities, and borrowing capacity under our three credit facilities will provide sufficient funds for our operating and capital needs for the foreseeable future.

Contractual Obligations and Commercial Commitments: Item 7 of Part II of our 2019 Form 10-K includes our disclosure of contractual obligations and commercial commitments as of December 31, 2019. There were no material changes in the nature of these items during the three months ended March 31, 2020.

Regulations:

Item 1 of Part I of our 2019 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 2019 Form 10-K.

Critical Accounting Estimates: The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires us 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 Estimates can be found in our 2019 Form 10-K. Estimates of accrued liabilities for insurance and claims for bodily injury, property damage and workers' compensation is a critical accounting estimate that requires us to make significant judgments and estimates and affects our financial statements.

There have been no material changes to this critical accounting estimate from that discussed in our 2019 Form 10-K.
