<div> <div> 10.  Commitments and Contingencies Lawsuits Norfolk Southern and/or certain subsidiaries are defendants in numerous lawsuits and other claims relating principally to railroad operations.  When management concludes that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, it is accrued through a charge to earnings.  While the ultimate amount of liability incurred in any of these lawsuits and claims is dependent on future developments, in management's opinion, the recorded liability is adequate to cover the future payment of such liability and claims.  However, the final outcome of any of these lawsuits and claims cannot be predicted with certainty, and unfavorable or unexpected outcomes could result in additional accruals that could be significant to results of operations in a particular year or quarter.  Any adjustments to the recorded liability will be reflected in earnings in the periods in which such adjustments are known. One of NS' customers, DuPont, has a rate reasonableness complaint pending before the Surface Transportation Board (STB) alleging that the NS tariff rates for transportation of regulated movements are unreasonable.  NS disputes these allegations.  Since June 1, 2009, NS has been billing and collecting from DuPont amounts based on the challenged tariff rates.  Management presently expects resolution of the case to occur in 2013 and believes the estimate of reasonably possible loss will not have a material effect on NS' financial position, results of operations, or liquidity.  With regard to rate cases, management records adjustments to revenues in the periods, if and when, such adjustments are probable and estimable. On November 6, 2007, various antitrust class actions filed against NS and other Class 1 railroads in various Federal district courts regarding fuel surcharges were consolidated in the District of Columbia by the Judicial Panel on Multidistrict Litigation.  NS believes the allegations in the complaints are without merit and intends to vigorously defend the cases.  NS does not believe that the outcome of these proceedings will have a material effect on its financial position, results of operations, or liquidity.  A lawsuit containing similar allegations against NS and four other major railroads that was filed on March 25, 2008, in the U.S. District Court for the District of Minnesota was voluntarily dismissed by the plaintiff subject to a tolling agreement entered into in August 2008. Casualty Claims Casualty claims include employee personal injury and occupational claims as well as third-party claims, all exclusive of legal costs.  To aid in valuing its personal injury liability and determining the amount to accrue with respect to such claims during the year, NS' management utilizes studies prepared by an independent consulting actuarial firm.  Job-related accidental injury and occupational claims are subject to the Federal Employers' Liability Act (FELA), which is applicable only to railroads.  FELA's fault-based system produces results that are unpredictable and inconsistent as compared with a no-fault workers' compensation system.  The variability inherent in this system could result in actual costs being different from the liability recorded.  While the ultimate amount of claims incurred is dependent on future developments, in management's opinion, the recorded liability is adequate to cover the future payments of claims and is supported by the most recent actuarial study.  In all cases, NS records a liability when the expected loss for the claim is both probable and estimable. The Consolidated Balance Sheets reflect long-term receivables for estimated recoveries from NS' insurance carriers for claims associated with the January 6, 2005, derailment in Graniteville, S.C.  In the first quarter of 2011, NS received an unfavorable ruling for an arbitration claim with an insurance carrier, and was denied recovery of the contested portion ($43 million) of the claim.  As a result, NS recorded a $43 million charge during the first quarter of 2011 for the receivables associated with the contested portion of the claim and a $15 million charge for other receivables affected by the ruling for which recovery was no longer probable. Employee personal injury claims – The largest component of casualties and other claims expense is employee personal injury costs.  The independent actuarial firm engaged by NS provides quarterly studies to aid in valuing its employee personal injury liability and estimating its employee personal injury expense.  The actuarial firm studies NS' historical patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences.  The actuary uses the results of these analyses to estimate the ultimate amount of liability, which includes amounts for incurred but unasserted claims. NS adjusts its liability quarterly based upon management's assessment and the results of the study.  The estimate of loss liabilities is subject to inherent limitation given the difficulty of predicting future events such as jury decisions, court interpretations, or legislative changes and as such the actual loss may vary from the estimated liability recorded. Occupational claims – Occupational claims (including asbestosis and other respiratory diseases, as well as conditions allegedly related to repetitive motion) are often not caused by a specific accident or event but rather allegedly result from a claimed exposure over time.  Many such claims are being asserted by former or retired employees, some of whom have not been employed in the rail industry for decades.  The independent actuarial firm provides an estimate of the occupational claims liability based upon NS' history of claim filings, severity, payments, and other pertinent facts.  The liability is dependent upon management's judgments made as to the specific case reserves as well as judgments of the consulting independent actuarial firm in the periodic studies.  The actuarial firm's estimate of ultimate loss includes a provision for those claims that have been incurred but not reported.  This provision is derived by analyzing industry data and projecting NS' experience into the future as far as can be reasonably determined.  NS adjusts its liability quarterly based upon management's assessment and the results of the study.  However, it is possible that the recorded liability may not be adequate to cover the future payment of claims.  Adjustments to the recorded liability are reflected in operating expenses in the periods in which such adjustments become known. Third-party claims – NS records a liability for third-party claims including those for highway crossing accidents, trespasser and other injuries, automobile liability, property damage, and lading damage.  The independent actuarial firm assists with the calculation of potential liability for third-party claims, except lading damage, based upon NS' experience including number and timing of incidents, amount of payments, settlement rates, number of open claims, and legal defenses. The actuarial estimate includes a provision for claims that have been incurred but have not yet been reported. Each quarter NS adjusts its liability based upon management's assessment and the results of the study.  Given the inherent uncertainty in regard to the ultimate outcome of third-party claims, it is possible that the actual loss may differ from the estimated liability recorded. Environmental Matters NS is subject to various jurisdictions' environmental laws and regulations.  It is NS' policy to record a liability where such liability or loss is probable and its amount can be estimated reasonably.  Claims, if any, against third parties for recovery of cleanup costs incurred by NS are reflected as receivables (when collection is probable) in the Consolidated Balance Sheets and are not netted against the associated NS liability.  Environmental engineers regularly participate in ongoing evaluations of all known sites and in determining any necessary adjustments to liability estimates.  NS also has an Environmental Policy Council, composed of senior managers, to oversee and interpret its environmental policy. NS' Consolidated Balance Sheets include liabilities for environmental exposures of $38 million at March 31, 2012, and $35 million at December 31, 2011 (of which $12 million is classified as a current liability at the end of each period).  At March 31, 2012, the liability represents NS' estimate of the probable cleanup and remediation costs based on available information at 143 known locations and projects.  As of that date, seven sites accounted for approximately $18 million of the liability, and no individual site was considered to be material.  NS anticipates that much of this liability will be paid out over five years; however, some costs will be paid out over a longer period. At 26 locations, one or more Norfolk Southern subsidiaries in conjunction with a number of other parties, have been identified as potentially responsible parties under the Comprehensive Environmental Response, Compensation and Liability Act of 1980, or comparable state statutes that impose joint and several liability for cleanup costs.  NS calculates its estimated liability for these sites based on facts and legal defenses applicable to each site and not solely on the basis of the potential joint liability. With respect to known environmental sites (whether identified by NS, the EPA or comparable state authorities), estimates of NS' ultimate potential financial exposure for a given site or in the aggregate for all such sites are necessarily imprecise because of the widely varying costs of currently available cleanup techniques, the likely development of new cleanup technologies, unpredictable contaminant recovery and reduction rates associated with available clean-up technologies, the difficulty of determining in advance the nature and full extent of contamination and each potential participant's share of any estimated loss (and that participant's ability to bear it), and evolving statutory and regulatory standards governing liability. The risk of incurring environmental liability – for acts and omissions, past, present, and future – is inherent in the railroad business.  Some of the commodities in NS' traffic mix, particularly those classified as hazardous materials, pose special risks that NS and its subsidiaries work diligently to minimize.  In addition, several NS subsidiaries own, or have owned, land used as operating property, or which is leased and operated by others, or held for sale.  Because environmental problems may exist on these properties that are latent or undisclosed, there can be no assurance that NS will not incur environmental liabilities or costs with respect to one or more of them, the amount and materiality of which cannot be estimated reliably at this time.  Moreover, lawsuits and claims involving these and potentially other unidentified environmental sites and matters are likely to arise from time to time.  The resulting liabilities could have a significant effect on financial position, results of operations, or liquidity in a particular year or quarter. Based on its assessment of the facts and circumstances now known, management believes that it has recorded the probable and reasonably estimable costs for dealing with those environmental matters of which NS is aware.  Further, management believes that it is unlikely that any known matters, either individually or in the aggregate, will have a material adverse effect on NS' financial position, results of operations, or liquidity. Insurance Norfolk Southern obtains on behalf of itself and its subsidiaries insurance for potential losses for third-party liability and first-party property damages.  NS is currently self-insured up to $50 million and above $1 billion per occurrence for bodily injury and property damage to third parties and up to $25 million and above $175 million per occurrence for property owned by NS or in NS' care, custody, or control. Purchase Commitments At March 31, 2012, NS had outstanding purchase commitments totaling approximately $481 million for long-term service contracts through 2019 as well as locomotives, track material, and freight cars, in connection with its capital programs through 2014.</div> </div>

During the first quarter of 2012, NS issued $600 million of 3.0% senior notes due 2022.

<div> 1.  Stock-Based Compensation During the first quarter of 2012, a committee of non-employee directors of Norfolk Southern's Board of Directors granted stock options, restricted stock units (RSUs) and performance share units (PSUs) pursuant to the Long-Term Incentive Plan (LTIP) and granted stock options pursuant to the Thoroughbred Stock Option Plan (TSOP) as discussed below.  Stock-based compensation expense was $34 million during the first quarter of 2012 and $42 million during the same period of 2011.  The total tax effects recognized in income in relation to stock-based compensation were net benefits of $11 million and $14 million for the quarters ended March 31, 2012 and 2011, respectively. Stock Options In the first quarter of 2012, 567,300 options were granted under the LTIP and 210,300 options were granted under the TSOP.  In each case, the grant price was $75.14, which was the greater of the average fair market value of Norfolk Southern common stock (Common Stock) or the closing price of the Common Stock on the effective date of the grant, and the options have a term of ten years.  The options granted under the LTIP and TSOP in 2012 may not be exercised prior to the fourth and third anniversaries of the date of grant, respectively.  Holders of the 2012 options granted under the LTIP who remain actively employed receive cash dividend equivalent payments for four years in an amount equal to the regular quarterly dividends paid on Common Stock.  Dividend equivalent payments are not made on TSOP options. The fair value of each option award in 2012 was measured on the date of grant using a lattice-based option valuation model.  Expected volatilities are based on implied volatilities from traded options on Common Stock and historical volatility of Common Stock.  NS uses historical data to estimate option exercises and employee terminations within the valuation model.  The average expected option life is derived from the output of the valuation model and represents the period of time that options granted are expected to be outstanding.  The average risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant.  For options granted that include dividend equivalent payments, a dividend yield of zero was used.  A dividend yield of 2.3% was used for LTIP options for periods where no dividend equivalent payments are made as well as for TSOP options, which do not receive dividend equivalents.  The assumptions for the 2012 LTIP and TSOP grants are shown in the following table: <table style="font-family: 'Calibri','sans-serif'; font-size: 11pt;" class="MsoNormalTable" border="0" cellpadding="0"> <tr><td style="padding-bottom: 0.75pt; padding-left: 0.75pt; width: 397.5pt; padding-right: 0.75pt; padding-top: 0.75pt;" width="530"> Expected volatility range</td> <td style="padding-bottom: 0.75pt; padding-left: 0.75pt; width: 78.75pt; padding-right: 0.75pt; padding-top: 0.75pt;" width="105"> 27% - 29%</td></tr> <tr><td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> Average expected volatility</td> <td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> 27%</td></tr> <tr><td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> LTIP average expected option life</td> <td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> 8.9 years</td></tr> <tr><td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> TSOP average expected option life</td> <td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> 8.8 years</td></tr> <tr><td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> Average risk-free interest rate</td> <td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> 1.96%</td></tr> <tr><td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> LTIP per-share grant-date fair value</td> <td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> $23.84</td></tr> <tr><td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> TSOP per-share grant-date fair value</td> <td style="padding-bottom: 0.75pt; padding-left: 0.75pt; padding-right: 0.75pt; padding-top: 0.75pt;"> $19.55</td></tr></table> For the first three months of 2012, options relating to 376,357 shares were exercised, yielding $11 million of cash proceeds and $6 million of tax benefit recognized as additional paid-in capital.  For the first three months of 2011, options relating to 759,193 shares were exercised yielding $20 million of cash proceeds and $10 million of tax benefit recognized as additional paid-in capital. Restricted Stock Units There were 140,000 RSUs granted in 2012, with an average grant-date fair value of $75.14 and a five-year restriction period.  The restricted stock units granted in 2012 will be settled through the issuance of shares of Common Stock. During the first quarter of 2012, 281,900 RSUs were earned and paid out.  The total related tax benefit recognized as additional paid-in capital was $3 million in the first quarter of 2012. During the first quarter of 2011, no RSUs were earned and paid out.  The total related tax benefit recognized as additional paid-in capital was less than $1 million in the first quarter of 2011. Performance Share Units PSUs provide for awards based on achievement of certain predetermined corporate performance goals (total shareholder return, return on average invested capital and operating ratio) at the end of a three-year cycle and are paid in the form of shares of Common Stock.  During the first quarter of 2012, there were 468,850 PSUs granted with a grant-date fair value of $75.14. During the first quarter of 2012, 782,889 PSUs were earned and paid out in shares of Common Stock.  The total related tax benefit recognized as additional paid-in capital was $11 million for the first quarter of 2012. During the first quarter of 2011, 850,595 PSUs were earned and paid out, one-half in shares of Common Stock and one-half in cash.  These PSUs had a grant-date fair value of $50.47 per unit and a fair value at payout of $62.75 per unit.  The total related tax benefit recognized as additional paid-in capital was $2 million for the first quarter of 2011. </div>

Fair Values of Financial Instruments NS has evaluated the fair values of financial instruments and methods used to determine those fair values.  The fair values of "Cash and cash equivalents," "Short-term investments," "Accounts receivable," "Accounts payable," and "Short-term debt" approximate carrying values because of the short maturity of these financial instruments.  The carrying value of corporate-owned life insurance is recorded at cash surrender value and, accordingly, approximates fair value.  The carrying amounts and estimated fair values for the remaining financial instruments excluding investments accounted for under the equity method consisted of the following: <table style="width: 661.5pt;
