Qualified and non-qualified pension benefits are based on years of service and the highest compensation during the latest years of employment, with specific reductions made for early retirements. Non-union employees hired on or after <em style="font: inherit;"> January 1, 2018, </em>are <em style="font: inherit;">no</em> longer eligible for pension benefits, but are eligible for an enhanced <em style="font: inherit;">401</em>(k) plan.</span></p>

   <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"><span style="color:#000000;">Pension expense is determined based upon the annual service cost of benefits (the actuarial cost of benefits earned during a period) and the interest cost on those liabilities, less the expected return on plan assets. The expected long-term rate of return on plan assets is applied to a calculated value of plan assets that recognizes changes in fair value over a <ix:nonNumeric contextRef="d_2022-01-01_2022-12-31" name="unp:DefinedBenefitPlanExpectedReturnOnPlanAssetsChangesInFairValuePeriod" id="c96664646" format="ixt-sec:duryear">5</ix:nonNumeric>-year period. This practice is intended to reduce year-to-year volatility in pension expense, but it can have the effect of delaying the recognition of differences between actual returns on assets and expected returns based on long-term rate of return assumptions. Differences in actual experience in relation to assumptions are <em style="font: inherit;">not</em> recognized in net income immediately, but are deferred in accumulated other comprehensive income/loss and, if necessary, amortized as pension expense.</span></p>

Cost estimates are based on information available for each site, financial viability of other potentially responsible parties, and existing technology, laws, and regulations. The ultimate liability for remediation is difficult to determine because of the number of potentially responsible parties, site-specific cost sharing arrangements with other potentially responsible parties, the degree of contamination by various wastes, the scarcity and quality of volumetric data related to many of the sites, and the speculative nature of remediation costs.

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"><span style="color: rgb(0, 0, 0); font-size: 10pt;">The</span>&#xa0;preparation of these financial statements requires estimation and judgment that affect the reported amounts of revenues, expenses, assets, and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. If these estimates differ materially from actual results, the impact on the Condensed Consolidated Financial Statements may be material. Our critical accounting estimates are available in Item 7 of <span style="color: rgb(0, 0, 0); font-size: 10pt;"> our </span>2022<span style="color: rgb(0, 0, 0); font-size: 10pt;"> Annual Report on Form 10-K. During the first three&#xa0;months of </span>2023<span style="color: rgb(0, 0, 0); font-size: 10pt;">, there have not been any significant changes with respect to the policies used to develop our critical accounting estimates.</span></p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"><span style="color:#000000;"><b>Quarterly Summary</b></span></p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;">&#xa0;</p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;">The Company reported earnings of $2.67 per diluted share on net income of $1.6&#xa0;billion and an operating ratio of 62.1%&#xa0;in the first quarter of 2023&#xa0;compared to earnings of $2.57 per diluted share on net income of $1.6&#xa0;billion and an operating ratio of 59.4% for the first quarter of 2022. Freight revenues increased 4% in the quarter compared to the same period in 2022&#xa0;driven by a 6% increase in average revenue per car (ARC), partially offset by a 1% decline in volume. The ARC increase was driven by higher fuel surcharge revenues and core pricing gains, partially offset by negative mix of traffic (for example, a relative decrease in forest products shipments, which have a higher ARC).&#xa0;Volume decreases were driven by a weaker market for domestic intermodal and forest products as well as service and weather interruptions, which reduced our ability to haul available coal demand.&#xa0;These declines were partially offset by increased production and inventory replenishment in the automotive industry, continued strength in rock shipments, and&#xa0;a domestic intermodal contract win.&#xa0;</p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;">&#xa0;</p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;">Although&#xa0;key metrics&#xa0;such as freight car velocity and terminal dwell improved sequentially, most of our service metrics declined or remained flat with last year&#x2019;s performance as this quarter was impacted by weather interruptions spread across the network. The addition of train, engine, and yard employees, up 5% compared to the first quarter of 2022, helped us mitigate the impacts of these events. We continue to hire and have a strong pipeline of individuals currently in training. Despite the additional resources, weather adversely impacted our service product and our ability to handle all the demand in certain markets.</p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;">&#xa0;</p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;">Operational challenges, including additional costs for weather, inflation, and higher fuel price drove an 8% increase in operating expenses.&#xa0;The increased costs more than offset the higher revenues, producing operating income of $2.3 billion, a 3% decrease from first quarter of 2022.&#xa0;The weather impact to our operating income, including lost revenue and increased expenses, was approximately $50 million and immaterial to our capital program.&#xa0;Our operating ratio was 62.1%, deteriorating 2.7 points from first quarter of 2022.</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">We generate freight revenues by transporting products from our three commodity groups. Freight revenues vary with volume (carloads) and ARC. Changes in price, traffic mix, and fuel surcharges drive ARC. Customer incentives, which are primarily provided for shipping to/from specific locations or based on cumulative volumes, are recorded as a reduction to operating revenues. Customer incentives that include variable consideration based on cumulative volumes are estimated using the expected value method, which is based on available historical, current, and forecasted volumes, and recognized as the related performance obligation is satisfied. We recognize freight revenues over time as shipments move from origin to destination. The allocation of revenues between reporting periods is based on the relative transit time in each reporting period with expenses recognized as incurred.</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">Other subsidiary revenues&#xa0;(primarily logistics and commuter rail operations) are generally recognized over time as shipments move from origin to destination. The allocation of revenues between reporting periods is based on the relative transit time in each reporting period with expenses recognized as incurred. Accessorial revenues are recognized at a point in time as performance obligations are&#xa0;satisfied.</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">Freight&#xa0;revenues increased 4% during the first quarter of 2023&#xa0;compared to 2022, resulting from higher fuel surcharge revenues&#xa0;and core pricing gains, partially offset by negative mix of traffic and lower volume.&#xa0;Volume declines were driven by a weak freight market for domestic intermodal due to high inventories and inflationary pressures impacting consumer demand, lower forest product shipments due to a softening housing market, lower coal shipments due to repeated weather-related outages, and a softening export grain market. These declines were partially offset by increased production and inventory replenishment in the automotive industry,&#xa0;continued strength in rock shipments, and&#xa0;a domestic intermodal contract win.&#xa0;</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">Each of our commodity groups includes revenues from fuel surcharges. Freight revenues from fuel surcharge programs increased to $883&#xa0;million in the first quarter of 2023 compared to $635&#xa0;million in the same period of 2022&#xa0;due to the lag impact on fuel surcharge (it can generally take up to two months for changing fuel prices to affect fuel surcharges&#xa0;recoveries) and higher fuel prices, partially offset by 1% lower volume.&#xa0;</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">Other subsidiary revenues increased in the first quarter&#xa0;of 2023&#xa0;compared to 2022&#xa0;primarily driven by increased equipment&#xa0;and fuel surcharge revenues on our automotive parts shipments at our subsidiary that brokers intermodal and transload logistics services. Accessorial revenues decreased in the first quarter&#xa0;of 2023&#xa0;compared to 2022&#xa0;driven by decreased intermodal accessorial and container revenues due to lower volume and improvements in the global supply chain as reflected by better equipment cycle times.</p>

  <p style="font-family: Arial; font-size: 10pt; margin: 0pt; text-align: justify;"><i>Bulk</i>&#xa0;&#x2013; Bulk includes shipments of grain and grain products, fertilizer, food and refrigerated, and coal and renewables. Freight revenues from bulk shipments increased in the first quarter of 2023 compared to 2022 due to higher fuel surcharge revenues and core pricing gains, partially offset by volume declines and negative mix. Volume declined 3% in the first quarter of 2023 compared to 2022 driven by decreases in coal and renewable shipments and food and refrigerated as both markets were impacted by outages and service challenges due to repeated snow events in Wyoming and flooding in California.</p>

  <p style="font-family: Arial; font-size: 10pt; margin: 0pt; text-align: justify;"><i>Industrial </i>&#x2013;&#xa0;Industrial includes shipments of industrial chemicals and plastics, metals and minerals, forest products, and energy and specialized markets. Freight revenues from industrial shipments increased in the first quarter of 2023 compared to 2022 due to higher fuel surcharge revenues and core pricing gains, partially offset by negative mix of traffic from decreased lumber shipments and&#xa0;increased short haul rock shipments.&#xa0;Volume declined slightly in the first quarter of 2023 compared to 2022.&#xa0;We saw growth in energy and specialized markets due to liquid petroleum gases (LPG) demand and new business wins, along with metals and minerals growth due to strong demand for rock&#xa0;and sand. That growth was more than offset by decreases in forest products due to the softening housing market and fewer shipments of brown paper as demand for non-durable goods declined.</p>

  <p style="font-family: Arial; font-size: 10pt; margin: 0pt; text-align: justify;"><i>Premium</i> &#x2013;&#xa0;Premium includes shipments of finished automobiles, automotive parts, and merchandise in intermodal containers, both domestic and international. Premium freight revenues increased in the first quarter of 2023 compared to 2022 due to higher fuel surcharge revenues and core pricing gains, partially offset by negative mix and volume declines. Intermodal shipments decreased 3% driven by the softening market due to high inventories and inflationary pressures impacting consumer demand, partially offset by domestic contract wins&#xa0;and improved global supply chain. Automotive shipments increased 5%&#xa0;in the first quarter of 2023 compared to the same periods in 2022 driven by increased production as dealers replenish inventories.&#xa0;</p>

  <p style="font-family: Arial; font-size: 10pt; margin: 0pt; text-align: justify;"><i>Mexico Business </i>&#x2013;&#xa0;Each of our commodity groups includes revenues from shipments to and from Mexico. Revenues from Mexico business increased 9% to $712&#xa0;million in the first quarter of 2023 compared to 2022 driven by higher fuel surcharge revenues, positive business mix from higher grain shipments, and core pricing gains. The volume was essentially flat as higher LPG, intermodal, and grain shipments were offset by fewer coal, steel, and grain products shipments.</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><i>Compensation and Benefits</i> &#x2013; Compensation and benefits include wages, payroll taxes, health and welfare costs, pension costs, and incentive costs. For the first quarter of 2023, expenses increased 7% compared to 2022 due to an increase in employee levels and wage inflation.&#xa0;The employee level increase of 4% includes a 5% increase in train, engine, and yard employees to support our training pipeline and address operational challenges.&#xa0;</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><i>Fuel</i> &#x2013; Fuel includes locomotive fuel and gasoline for highway and non-highway vehicles and heavy equipment. Fuel expense increased in the first quarter of 2023 compared to the same period in 2022 driven by a&#xa0;9% increase in locomotive diesel fuel prices, which averaged $3.22 and $2.95 per gallon (including taxes and transportation costs) in the first quarter of 2023 and 2022, respectively.&#xa0;A&#xa0;1% increase in the fuel consumption rate, computed as gallons of fuel consumed divided by gross ton-miles in thousands also contributed to the higher expense.&#xa0;Partially offsetting these increases was a 1% decrease in gross ton-miles.</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><i>Purchased Services and Materials</i> &#x2013; Expense for purchased services and materials includes the costs of services purchased from outside contractors and other service providers&#xa0;(including equipment maintenance and contract expenses incurred by our subsidiaries for external transportation services); materials used to maintain the Railroad&#x2019;s lines, structures, and equipment; costs of operating facilities jointly used by UPRR and other railroads; transportation and lodging for train crew employees; trucking and contracting costs for intermodal containers; leased automobile maintenance expenses; and tools and supplies. Purchased services and materials increased 16% in the first quarter of 2023 compared to 2022 primarily due to inflation&#xa0;and higher locomotive maintenance expenses&#xa0;due to a larger active fleet to assist in recovering the network.</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><i>Depreciation</i> &#x2013; The majority of depreciation relates to road property, including rail, ties, ballast, and other track material. Depreciation expense was up 3% for the first quarter of 2023 compared to 2022.</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"><i>Equipment and Other Rents</i> &#x2013;&#xa0;Equipment and other rents expense primarily includes rental expense that the Railroad pays for freight cars owned by other railroads or private companies; freight car, intermodal, and locomotive leases; and office and other rent expense, offset by equity income from certain equity method investments.&#xa0;Equipment and other rents expense increased 9% in the first quarter of 2023 compared to 2022 driven by elongated cycle time related to operational challenges and inflation.</p>

Other costs increased 6% in the first quarter of 2023 compared to 2022 driven by higher environmental remediation costs.</p>

  <p style="margin: 0pt; font-family: Arial; font-size: 10pt; text-align: justify;"><i>Gross and Revenue Ton-Miles</i> &#x2013; Gross ton-miles are calculated by multiplying the weight of loaded and empty freight cars by the number of miles hauled. Revenue ton-miles are calculated by multiplying the weight of freight by the number of tariff miles. Gross ton-miles and revenue ton-miles decreased 1% and 3%, respectively, during the first quarter of 2023 compared to 2022, driven by a 1% decline in carloadings. Changes in commodity mix drove the variances in year-over-year decreases between gross ton-miles, revenue ton-miles, and carloads (higher decreases in bulk shipments, which are generally heavier).</p>

  <p style="margin: 0pt; font-family: Arial; font-size: 10pt; text-align: justify;"><i>Freight Car Velocity</i> &#x2013;&#xa0;Freight car velocity measures the average daily miles per car on our network. The two key drivers of this metric are the speed of the train between terminals (average train speed) and the time a rail car spends at the terminals (average terminal dwell time).&#xa0;Despite the operational challenges caused by the weather, we were able to maintain our average train speed and average terminal dwell compared to the same period in 2022.</p>

Locomotive productivity decreased in the first quarter of 2023 compared to the same periods in 2022 driven by an increase in our average active fleet size as resources were deployed to alleviate operational challenges caused by weather.</p>

Our network car trip plan compliance is broken into the intermodal and manifest/automotive products. Intermodal car trip plan compliance improved 1 point&#xa0;and manifest/automotive&#xa0;car trip plan compliance&#xa0;deteriorated 1 point&#xa0;in the first quarter of 2023 compared to 2022.</p>

Workforce productivity decreased 6% in the first quarter of 2023, as average daily car miles decreased 2%&#xa0;and employees increased 4% compared to 2022. The 4% increase in employee levels was driven by an increase in craft professionals.&#xa0;We continue to aggressively hire train, engine, and yard employees to support our training pipeline and address operational challenges.&#xa0;In addition, mechanical craft professionals increased year-over-year to maintain our higher active fleet.</p>

Our first quarter of 2023 operating ratio of 62.1% deteriorated 2.7 points compared to 2022 due to excess network costs, inflation, negative mix of traffic, and other cost increases, partially offset by higher fuel prices and core pricing gains.&#xa0;</p>

We believe this measure is important to management and investors in evaluating the Company&#x2019;s ability to sustain given debt levels (including leases) with the cash generated from operations. In addition, a comparable measure is used by rating agencies when reviewing the Company&#x2019;s credit rating. Adjusted debt to adjusted EBITDA should be considered in addition to, rather than as a substitute for, net income. The table above provides a reconciliation&#xa0;from net income to adjusted EBITDA and debt to adjusted debt. At </span>March 31, 2023<span style="color:#000000;">, and </span>December 31, 2022<span style="color:#000000;">, the incremental borrowing rate on operating leases was&#xa0;3.4% and 3.3%, respectively.</span></p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">We are continually evaluating our financial condition and liquidity. We analyze a wide range of economic scenarios and the impact on our ability to generate cash. These analyses inform our liquidity plans and activities outlined below and indicate we have sufficient borrowing capacity to sustain an extended period of lower volumes.</p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">&#xa0;</p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">During the first&#xa0;quarter of 2023, we generated $<span style="color: #000000; ">1.8</span>&#xa0;billion of cash provided by operating activities, paid our quarterly dividend,&#xa0;and repurchased $591&#xa0;million&#xa0;worth of shares under our share repurchase programs.&#xa0;On March&#xa0;31, 2023, we had $<span style="color:#000000;">1.1</span>&#xa0;billion of cash and cash equivalents, $2.0 billion of credit available under our revolving credit facility, and&#xa0;$800 million undrawn on the Receivables Facility. In the first&#xa0;quarter of 2023, we issued $1.0&#xa0;billion in fixed-rate long-term debt. Additionally, we paid down $100 million on the Receivables Facility.&#xa0;We have been, and we expect to continue to be, in compliance with our debt covenants.</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">As described in the notes to the Condensed Consolidated Financial Statements and as referenced in the table below, we have contractual obligations that may affect our financial condition. Based on our assessment of the underlying provisions and circumstances of our contractual obligations, other than the risks that we and other similarly situated companies face with respect to the condition of the capital markets, as of the date of this filing, there is no known trend, demand, commitment, event, or uncertainty that is reasonably likely to occur that would have a material adverse effect on our consolidated results of operations, financial condition, or liquidity. In addition, our commercial obligations, financings, and commitments are customary transactions that are like those of other comparable corporations, particularly within the transportation industry.</p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"><span style="color:#000000;">As of the end of the period covered by this report, the Corporation carried out an evaluation, under the supervision and with the participation of the Corporation&#x2019;s management, including the Corporation&#x2019;s Chief Executive Officer (CEO) and Executive Vice President and Chief Financial Officer (CFO), of the effectiveness of the design and operation of the Corporation&#x2019;s disclosure controls and procedures pursuant to Exchange Act Rules 13a-15 and 15d-15. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. Based upon that evaluation, the CEO and the CFO concluded that, as of the end of the period covered by this report, the Corporation&#x2019;s disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified by the SEC, and that such information is accumulated and communicated to management, including the CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.</span></p>

We routinely assess our liabilities and contingencies in connection with these matters based upon the latest available information and, when necessary, we seek input from our third-party advisors when making these assessments. Consistent with SEC rules and requirements, we describe below material pending legal proceedings (other than ordinary routine litigation incidental to our business), material proceedings known to be contemplated by governmental authorities, other proceedings arising under federal, state, or local environmental laws and regulations (including governmental proceedings involving potential fines, penalties, or other monetary sanctions in excess of $1,000,000), and such other pending matters that we may determine to be appropriate.</span></p>

  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"><span style="color:#000000;">As provided in our Form 10-Q for the quarter ended September 30, 2022, and filed on October 20, 2022, in December 2019, truck driver David Fleury (Fleury) filed a putative class action complaint against Union Pacific Railroad Company in the United States District Court for the Northern District of Illinois (the District Court) raising claims under the Illinois Biometric Information Privacy Act, 740 ILCS 14/1, <i>et seq.</i> (the Act). Members of the putative class are third-party truck drivers who gained access to Union Pacific intermodal terminals in Illinois by verifying their identity using finger-scan technology. The complaint alleges Union Pacific&#x2019;s use of the finger scan system violated the Act by capturing Fleury&#x2019;s biometric information.&#xa0;The parties are currently engaged in the discovery process and no class has been certified.</span></p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;">&#xa0;</p>
  <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"><span style="color:#000000;">While we believe that we have strong defenses to the complaint and will vigorously defend the case, there is no assurance regarding the ultimate outcome. Therefore, the outcome of this litigation is inherently uncertain, and we cannot reasonably estimate any loss or range of loss that may arise from this matter.</span></p>

We cannot predict the ultimate impact of these proceedings and suits because of the number of potentially responsible parties involved, the degree of contamination by various wastes, the scarcity and quality of volumetric data related to many of the sites,&#xa0;</span><span style="color:#000000;">and the speculative nature of remediation costs.</span></p>

   <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"><span style="color:#000000;">We provide defined benefit retirement income to eligible non-union employees through qualified and non-qualified (supplemental) pension plans. Qualified and non-qualified pension benefits are based on years of service and the highest compensation during the latest years of employment, with specific reductions made for early retirements. Non-union employees hired on or after <em style="font: inherit;"> January 1, 2018, </em>are <em style="font: inherit;">no</em> longer eligible for pension benefits, but are eligible for an enhanced <em style="font: inherit;">401</em>(k) plan.</span></p>

   <p style="font-family: Arial; font-size: 10pt; font-variant: normal; margin: 0pt;">&#160;</p>
   <p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"><span style="color:#000000;">Pension expense is determined based upon the annual service cost of benefits (the actuarial cost of benefits earned during a period) and the interest cost on those liabilities, less the expected return on plan assets. The expected long-term rate of return on plan assets is applied to a calculated value of plan assets that recognizes changes in fair value over a 5-year period. This practice is intended to reduce year-to-year volatility in pension expense, but it can have the effect of delaying the recognition of differences between actual returns on assets and expected returns based on long-term rate of return assumptions. Differences in actual experience in relation to assumptions are <em style="font: inherit;">not</em> recognized in net income immediately, but are deferred in accumulated other comprehensive income/loss and, if necessary, amortized as pension expense.</span></p>

   <p style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;">In <em style="font: inherit;"> December 2019, </em>we received a putative class action complaint under the Illinois Biometric Information Privacy Act, alleging violation due to the use of a finger scan system developed and managed by <em style="font: inherit;">third</em> parties. Union Pacific and the plaintiff are currently in the discovery phase. While we believe that we have strong defenses to the complaint and will vigorously defend the case, there is <em style="font: inherit;">no</em> assurance regarding the ultimate outcome. Therefore, the outcome of this litigation is inherently uncertain, and we cannot reasonably estimate any loss or range of loss that <em style="font: inherit;"> may </em>arise from this matter.</p>

Cost estimates are based on information available for each site, financial viability of other potentially responsible parties, and existing technology, laws, and regulations. The ultimate liability for remediation is difficult to determine because of the number of potentially responsible parties, site-specific cost sharing arrangements with other potentially responsible parties, the degree of contamination by various wastes, the scarcity and quality of volumetric data related to many of the sites, and the speculative nature of remediation costs. Estimates of liability <em style="font: inherit;"> may </em>vary over time due to changes in federal, state, and local laws governing environmental remediation.

Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.</p></div>

The basic terms of these&#160;performance stock units are identical to those granted in &lt;em style="font: inherit;"&gt; February &lt;/em&gt;&lt;em style="font: inherit;"&gt;2022&lt;/em&gt;, including the annual return on invested capital (ROIC) and operating income growth (OIG) performance targets. The OIG performance targets compare to&#160;companies in the S&amp;amp;P &lt;em style="font: inherit;"&gt;100&lt;/em&gt; Industrials&#160;Index plus the Class I railroads. We define ROIC as net operating profit adjusted for interest expense (including interest on average operating lease liabilities) and taxes on interest divided by average invested capital adjusted for average operating lease liabilities.&lt;/span&gt;&lt;/p&gt;

We expense &lt;em style="font: inherit;"&gt;two&lt;/em&gt;-thirds of the fair value of the units that are probable of being earned based on our forecasted ROIC over the &lt;em style="font: inherit;"&gt;three&lt;/em&gt;-year performance period, and with respect to the &lt;em style="font: inherit;"&gt;third&lt;/em&gt; year of the plan, the remaining &lt;em style="font: inherit;"&gt;one&lt;/em&gt;-&lt;em style="font: inherit;"&gt;third&lt;/em&gt; of the fair value is subject to the relative &lt;em style="font: inherit;"&gt;three&lt;/em&gt;-year OIG. We measure the fair value of performance stock units based upon the closing price of the underlying common stock as of the date of grant. Dividend equivalents are accumulated during the service period and paid to participants only after the units are earned.&#160;&lt;/span&gt;

   &lt;p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"&gt;&lt;span style="color:#000000;"&gt;We provide defined benefit retirement income to eligible non-union employees through qualified and non-qualified (supplemental) pension plans. Qualified and non-qualified pension benefits are based on years of service and the highest compensation during the latest years of employment, with specific reductions made for early retirements. Non-union employees hired on or after &lt;em style="font: inherit;"&gt; January 1, 2018, &lt;/em&gt;are &lt;em style="font: inherit;"&gt;no&lt;/em&gt; longer eligible for pension benefits, but are eligible for an enhanced &lt;em style="font: inherit;"&gt;401&lt;/em&gt;(k) plan.&lt;/span&gt;&lt;/p&gt;

   &lt;p style="font-family: Arial; font-size: 10pt; font-variant: normal; text-align: justify; margin: 0pt;"&gt;&lt;span style="color:#000000;"&gt;Pension expense is determined based upon the annual service cost of benefits (the actuarial cost of benefits earned during a period) and the interest cost on those liabilities, less the expected return on plan assets. The expected long-term rate of return on plan assets is applied to a calculated value of plan assets that recognizes changes in fair value over a 5-year period. This practice is intended to reduce year-to-year volatility in pension expense, but it can have the effect of delaying the recognition of differences between actual returns on assets and expected returns based on long-term rate of return assumptions. Differences in actual experience in relation to assumptions are &lt;em style="font: inherit;"&gt;not&lt;/em&gt; recognized in net income immediately, but are deferred in accumulated other comprehensive income/loss and, if necessary, amortized as pension expense.&lt;/span&gt;&lt;/p&gt;

The fair value of the Corporation&#x2019;s debt is a measure of its current value under present market conditions. The fair value of our cash equivalents approximates their carrying value due to the short-term maturities of these instruments.&lt;/span&gt;&lt;/p&gt;

The Facility does &lt;em style="font: inherit;"&gt;not&lt;/em&gt; include any other financial restrictions, credit rating triggers (other than rating-dependent pricing), or any other provision that could require us to post collateral.

We cannot fully determine the effect of all asserted and unasserted claims on our consolidated results of operations, financial condition, or liquidity. To the extent possible, we have recorded a liability where asserted and unasserted claims are considered probable and where such claims can be reasonably estimated. We currently do &lt;em style="font: inherit;"&gt;not&lt;/em&gt; expect that any known lawsuits, claims, environmental costs, commitments, contingent liabilities, or guarantees will have a material adverse effect on our consolidated results of operations, financial condition, or liquidity after taking into account liabilities and insurance recoveries previously recorded for these matters.&lt;/span&gt;&lt;/p&gt;

   &lt;p style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt; font-variant: normal; margin: 0pt; text-align: justify;"&gt;In &lt;em style="font: inherit;"&gt; December 2019, &lt;/em&gt;we received a putative class action complaint under the Illinois Biometric Information Privacy Act, alleging violation due to the use of a finger scan system developed and managed by &lt;em style="font: inherit;"&gt;third&lt;/em&gt; parties. Union Pacific and the plaintiff are currently in the discovery phase. While we believe that we have strong defenses to the complaint and will vigorously defend the case, there is &lt;em style="font: inherit;"&gt;no&lt;/em&gt; assurance regarding the ultimate outcome. Therefore, the outcome of this litigation is inherently uncertain, and we cannot reasonably estimate any loss or range of loss that &lt;em style="font: inherit;"&gt; may &lt;/em&gt;arise from this matter.&lt;/p&gt;
   &lt;p style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt; font-variant: normal; margin: 0pt;"&gt;&#160;&lt;/p&gt;

Under FELA, damages are assessed based on a finding of fault through litigation or out-of-court settlements. We offer a comprehensive variety of services and rehabilitation programs for employees who are injured at work.&lt;/span&gt;&lt;/p&gt;

Because of the uncertainty surrounding the ultimate outcome of personal injury claims, it is reasonably possible that future costs to settle these claims &lt;em style="font: inherit;"&gt; may &lt;/em&gt;range from approximately $379&#160;million to $488&#160;million. We record an accrual at the low end of the range as &lt;em style="font: inherit;"&gt;no&lt;/em&gt; amount of loss within the range is more probable than any other. Estimates can vary over time due to evolving trends in litigation.&lt;/span&gt;&lt;/p&gt;

Cost estimates are based on information available for each site, financial viability of other potentially responsible parties, and existing technology, laws, and regulations. The ultimate liability for remediation is difficult to determine because of the number of potentially responsible parties, site-specific cost sharing arrangements with other potentially responsible parties, the degree of contamination by various wastes, the scarcity and quality of volumetric data related to many of the sites, and the speculative nature of remediation costs. Estimates of liability &lt;em style="font: inherit;"&gt; may &lt;/em&gt;vary over time due to changes in federal, state, and local laws governing environmental remediation. Current obligations are &lt;em style="font: inherit;"&gt;not&lt;/em&gt; expected to have a material adverse effect on our consolidated results of operations, financial condition, or liquidity.&lt;/span&gt;&lt;/p&gt;

Due to uncertainty as to whether claims will be made or how they will be resolved, we cannot reasonably determine the probability of an adverse claim or reasonably estimate any adverse liability or the total maximum exposure under these indemnification arrangements.

We expect to fund any share repurchases under this program through cash generated from operations, the sale or lease of various operating and non-operating properties, debt issuances, and cash on hand. Open market repurchases are recorded in treasury stock at cost, which includes any applicable commissions, fees, and excise taxes.&lt;/span&gt;&lt;/p&gt;

These ASRs have been structured so that at the time of commencement, we pay a specified amount to the financial institutions and receive an initial delivery of shares. Additional shares &lt;em style="font: inherit;"&gt; may &lt;/em&gt;be received at the time of settlement. The final number of shares to be received is based on the volume weighted average price of the Company&#x2019;s common stock during the ASR term, less a discount and subject to potential adjustments pursuant to the terms of such ASR.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;

Upon settlement of these ASRs in the &lt;em style="font: inherit;"&gt;second&lt;/em&gt; quarter of &lt;em style="font: inherit;"&gt;2022,&lt;/em&gt; we received&#160;&lt;/span&gt;1,847,185&#160;additional shares.&lt;/p&gt;

The Company reflects shares received as a repurchase of common stock in the weighted average common shares outstanding calculation for basic and diluted earnings per share.&lt;/span&gt;&lt;/span&gt;&lt;/p&gt;
