Accounting Policies [Abstract] | |||||||||||||||||||||
Summary Of Significant Accounting Policies | Summary of Significant Accounting Policies Description of Business Norfolk Southern Corporation is a Virginia-based holding company engaged principally in the rail transportation business, operating approximately 19,500 route miles primarily in the East and Midwest. These consolidated financial statements include Norfolk Southern and its majority-owned and controlled subsidiaries (collectively, NS, we, us, and our). Norfolk Southern’s major subsidiary is NSR. All significant intercompany balances and transactions have been eliminated in consolidation. NSR and its railroad subsidiaries transport raw materials, intermediate products, and finished goods classified in the following commodity groups (percent of total railway operating revenues in 2018): intermodal (25%); coal (16%); chemicals (16%); agriculture, consumer products, and government (14%); metals and construction (13%); automotive (9%); and, paper, clay, and forest products (7%). Although most of our customers are domestic, ultimate points of origination or destination for some of the products transported (particularly coal bound for export and some intermodal containers) may be outside the U.S. Approximately 80% of our railroad employees are covered by collective bargaining agreements with various labor unions. Use of Estimates The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We periodically review our estimates, including those related to the recoverability and useful lives of assets, as well as liabilities for litigation, environmental remediation, casualty claims, income taxes and pension and other postretirement benefits. Changes in facts and circumstances may result in revised estimates. Revenue Recognition Transportation revenue is recognized proportionally as a shipment moves from origin to destination, and related expenses are recognized as incurred. Certain of our contract refunds (which are primarily volume-based incentives) are recorded as a reduction to revenues on the basis of management’s best estimate of projected liability, which is based on historical activity, current shipment counts and expectation of future activity. Switching, demurrage and other incidental service revenues are recognized at a point in time when the services are performed or as contractual obligations are met. Cash Equivalents “Cash equivalents” are highly liquid investments purchased three months or less from maturity. Allowance for Doubtful Accounts Our allowance for doubtful accounts was $7 million at both December 31, 2018 and 2017. To determine our allowance for doubtful accounts, we evaluate historical loss experience (which has not been significant), the characteristics of current accounts, and general economic conditions and trends. Materials and Supplies “Materials and supplies,” consisting mainly of items for maintenance of property and equipment, are stated at the lower of average cost or net realizable value. The cost of materials and supplies expected to be used in property additions or improvements is included in “Properties.” Investments Investments in entities over which we have the ability to exercise significant influence but do not control the entity are accounted for using the equity method, whereby the investment is carried at the cost of the acquisition plus our equity in undistributed earnings or losses since acquisition. Properties “Properties” are stated principally at cost and are depreciated using the group method whereby assets with similar characteristics, use, and expected lives are grouped together in asset classes and depreciated using a composite depreciation rate. This methodology treats each asset class as a pool of resources, not as singular items. We use approximately 75 depreciable asset classes. “Depreciation” in the Consolidated Statements of Cash Flows includes both depreciation and depletion on operating and nonoperating properties. Depreciation expense is based on our assumptions concerning expected service lives of our properties as well as the expected net salvage that will be received upon their retirement. In developing these assumptions, we utilize periodic depreciation studies that are performed by an independent outside firm of consulting engineers and approved by the STB. Our depreciation studies are conducted about every three years for equipment and every six years for track assets and other roadway property. The frequency of these studies is consistent with guidelines established by the STB. We adjust our rates based on the results of these studies and implement the changes prospectively. The studies may also indicate that the recorded amount of accumulated depreciation is deficient (or in excess) of the amount indicated by the study. Any such deficiency (or excess) is amortized as a component of depreciation expense over the remaining service lives of the affected class of property, as determined by the study. Key factors that are considered in developing average service life and salvage estimates include:
The composite depreciation rate for rail in high density corridors is derived based on consideration of annual gross tons as compared to the total or ultimate capacity of rail in these corridors. Our experience has shown that traffic density is a leading factor in the determination of the expected service life of rail in high density corridors. In developing the respective depreciation rate, consideration is also given to several rail characteristics including age, weight, condition (new or second-hand) and type (curved or straight). We capitalize interest on major projects during the period of their construction. Expenditures, including those on leased assets, that extend an asset’s useful life or increase its utility are capitalized. Expenditures capitalized include those that are directly related to a capital project and may include materials, labor and equipment, in addition to an allocable portion of indirect costs that relate to a capital project. A significant portion of annual capital spending relates to the replacement of self-constructed assets. Removal activities occur in conjunction with replacement and are estimated based on the average percentage of time employees replacing assets spend on removal functions. Costs related to repairs and maintenance activities that do not extend an asset’s useful life or increase its utility are expensed when such repairs are performed. When depreciable operating road and equipment assets are sold or retired in the ordinary course of business, the cost of the assets, net of sale proceeds or salvage, is charged to accumulated depreciation, and no gain or loss is recognized in earnings. Actual historical cost values are retired when available, such as with most equipment assets. The use of estimates in recording the retirement of certain roadway assets is necessary based on the impracticality of tracking individual asset costs. When retiring rail, ties and ballast, we use statistical curves that indicate the relative distribution of the age of the assets retired. The historical cost of other roadway assets is estimated using a combination of inflation indices specific to the rail industry and those published by the U.S. Bureau of Labor Statistics. The indices are applied to the replacement value based on the age of the retired assets. These indices are used because they closely correlate with the costs of roadway assets. Gains and losses on disposal of operating land are included in “Materials and other” expenses. Gains and losses on disposal of nonoperating land and nonrail assets are included in “Other income – net” since such income is not a product of our railroad operations. A retirement is considered abnormal if it does not occur in the ordinary course of business, if it relates to disposition of a large segment of an asset class and if the retirement varies significantly from the retirement profile identified through our depreciation studies, which inherently consider the impact of normal retirements on expected service lives and depreciation rates. Gains or losses from abnormal retirements would be recognized in income from railway operations. We review the carrying amount of properties whenever events or changes in circumstances indicate that such carrying amount may not be recoverable based on future undiscounted cash flows. Assets that are deemed impaired as a result of such review are recorded at the lower of carrying amount or fair value. New Accounting Pronouncements The FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” and related amendments, which are jointly referred to as Accounting Standards Codification (ASC) Topic 606. This standard replaced most existing revenue recognition guidance in GAAP and requires entities to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. A performance obligation is defined as a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. We adopted the provisions of this standard on January 1, 2018, using the modified retrospective method. There was no cumulative effect of initially applying the standard, nor is there any material difference in revenue for the year ended December 31, 2018, as compared with GAAP that was in effect prior to January 1, 2018. In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This update requires segregation of net benefit costs between operating and nonoperating expenses and requires retrospective application. We adopted the standard on January 1, 2018. Under the new standard, only the service cost component of defined benefit pension cost and postretirement benefit cost are reported within “Compensation and benefits” and all other components of net benefit cost are presented in “Other income – net” on the Consolidated Statements of Income, whereas under the previous standard all components were included in “Compensation and benefits.” The retrospective application resulted in an increase to “Compensation and benefits” expense and an offsetting increase to “Other income – net” on the Consolidated Statements of Income of $64 million and $65 million for the years ended December 31, 2017 and December 31, 2016, respectively, with no impact on “Net income.” In February 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This update is intended to reclassify the stranded tax effects resulting from tax reform from accumulated other comprehensive income (AOCI) to retained earnings. The amount of the reclassification is the difference between the amount initially charged or credited directly to other comprehensive income at the previously enacted U.S. federal corporate income tax rate that remains in AOCI and the amount that would have been charged or credited directly to other comprehensive income using the newly enacted U.S. federal corporate income tax rate. In the first quarter of 2018, we adopted the provisions of ASU 2018-02 resulting in an increase to “Accumulated other comprehensive loss” of $88 million and a corresponding increase to “Retained income,” with no impact on “Total stockholders’ equity.” In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” and subsequent amendments, which replaced existing lease guidance in GAAP and requires lessees to recognize right-of-use (ROU) assets and lease liabilities on the balance sheet for leases greater than twelve months and disclose key information about leasing arrangements. We adopted the standard on January 1, 2019 using the modified retrospective method and used the effective date as our date of initial application. Financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. The new standard provides a number of optional practical expedients for transition. We elected the package of practical expedients under the transition guidance which permits us not to reassess under the new standards our prior conclusions for lease identification and lease classification on expired or existing contracts and whether initial direct costs previously capitalized would qualify for capitalization under ASC 842. We also elected the practical expedient related to land easements, allowing us to not reasses our current accounting treatment for existing agreements on land easements, which are not accounted for as leases. We did not elect the hindsight practical expedient to determine the reasonably certain lease term for existing leases. The new standard also provides practical expedients and recognition exemptions for an entity’s ongoing accounting policy elections. We elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities. We also elected the practical expedient not to separate lease and non-lease components for all of our leases. We expect that adoption of the standard will result in recognition of lease liabilities of approximately $600 million as of January 1, 2019, with corresponding ROU assets of the same amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. There will be no adjustment to “Retained income” on adoption. In June 2016, the FASB issued ASU 2016-13, “Credit Losses - Measurement of Credit Losses on Financial Instruments,” which replaces the current incurred loss impairment method with a method that reflects expected credit losses. The new standard is effective as of January 1, 2020, and early adoption is permitted as of January 1, 2019. Because credit losses associated from our trade receivables have historically been insignificant, we do not expect this standard to have a material effect on our financial statements. We will not adopt the standard early. |

Revenue from Contract with Customer [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Railway Operating Revenues | Railway Operating Revenues The following table disaggregates our revenues by commodity group:
A performance obligation is created when a customer under a transportation contract or public tariff submits a bill of lading to NS for the transport of goods. These performance obligations are satisfied as the shipments move from origin to destination. As such, transportation revenue is recognized proportionally as a shipment moves, and related expenses are recognized as incurred. These performance obligations are generally short-term in nature with transit days averaging approximately one week or less for each commodity group. The customer has an unconditional obligation to pay for the service once the service has been completed. Estimated revenue associated with in-process shipments at period-end is recorded based on the estimated percentage of service completed to total transit days. We had no material remaining performance obligations as of December 31, 2018. Under the typical payment terms of our freight contracts, payment for services is due within fifteen days of billing the customer, thus there are no significant financing components. “Accounts receivable – net” on the Consolidated Balance Sheets includes both customer and non-customer receivables as follows:
Non-customer receivables include non-revenue-related amounts due from other railroads, governmental entities, and others. “Other assets” on the Consolidated Balance Sheets includes non-current customer receivables of $55 million and $39 million at December 31, 2018 and December 31, 2017, respectively. We do not have any material contract assets or liabilities. Certain of our contracts contain refunds (which are primarily volume-based incentives) that are recorded as a reduction to revenue. Refunds are recorded on the basis of management’s best estimate of projected liability, which is based on historical activity, current shipment counts and expectation of future activity. Certain accessorial services may be provided to customers under their transportation contracts such as switching, demurrage and other incidental service revenues. These are distinct performance obligations that are recognized at a point in time when the services are performed or as contractual obligations are met. This revenue is included within each of the commodity groups and represents approximately 4% of total “Railway operating revenues” on the Consolidated Statements of Income. |

Income Taxes | Income Taxes Tax reform, enacted in 2017, lowered the Federal corporate tax rate from 35% to 21% and made numerous other tax law changes. GAAP requires companies to recognize the effect of tax law changes in the period of enactment. As a result, in 2017, “Purchased services and rents” included a $151 million benefit for earnings generated from reductions to net deferred tax liabilities at certain equity investees and “Income taxes” included a $3,331 million benefit primarily due to the remeasurement of our net deferred tax liabilities to reflect the lower rate. In 2017, reasonable estimates were made based on our analysis of tax reform that could have required provisional amounts to be adjusted when additional information was obtained. No material adjustments to our provisional amounts were made in 2018.
Reconciliation of Statutory Rate to Effective Rate “Income taxes” on the Consolidated Statements of Income differs from the amounts computed by applying the statutory federal corporate tax rate as follows:
Deferred Tax Assets and Liabilities Certain items are reported in different periods for financial reporting and income tax purposes. Deferred tax assets and liabilities are recorded in recognition of these differences. The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows:
Except for amounts for which a valuation allowance has been provided, we believe that it is more likely than not that the results of future operations will generate sufficient taxable income to realize the deferred tax assets. The valuation allowance at the end of each year primarily relates to subsidiary state income tax net operating losses and state investment tax credits that may not be utilized prior to their expiration. The total valuation allowance increased by $6 million in 2018, $5 million in 2017, and $4 million in 2016. Uncertain Tax Positions A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
Included in the balance of unrecognized tax benefits at December 31, 2018 are potential benefits of $17 million that would affect the effective tax rate if recognized. Unrecognized tax benefits are adjusted in the period in which new information about a tax position becomes available or the final outcome differs from the amount recorded. The statute of limitations on IRS examinations has expired for all years prior to 2015. We have amended our 2012 income tax return to request a refund of $46 million, which is not included in the above balance of unrecognized tax benefits. State income tax returns generally are subject to examination for a period of three to four years after filing of the return. In addition, we are generally obligated to report changes in taxable income arising from federal income tax examinations to the states within a period of up to two years from the date the federal examination is final. We have various state income tax returns either under examination, administrative appeal, or litigation. |

Fair Value Disclosures [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Fair Value Measurements | Fair Value Measurements FASB ASC 820-10, “Fair Value Measurements,” established a framework for measuring fair value and a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels, as follows:
The asset’s or liability’s fair value measurement level within the hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Fair Values of Financial Instruments The fair values of “Cash and cash equivalents,” “Accounts receivable – net,” “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. There are no other assets or liabilities measured at fair value on a recurring basis at December 31, 2018 or 2017. The carrying amounts and estimated fair values, based on Level 1 inputs, of long-term debt consisted of the following at December 31:

Investment in Conrail Through a limited liability company, we and CSX jointly own Conrail, whose primary subsidiary is CRC. We have a 58% economic and 50% voting interest in the jointly owned entity, and CSX has the remainder of the economic and voting interests. We are amortizing the excess of the purchase price over Conrail’s net equity using the principles of purchase accounting, based primarily on the estimated useful lives of Conrail’s depreciable property and equipment, including the related deferred tax effect of the differences in book and tax accounting bases for such assets, as all of the purchase price at acquisition was allocable to Conrail’s tangible assets and liabilities. At December 31, 2018, based on the funded status of Conrail’s pension plans, we decreased our proportional investment in Conrail by $11 million. This resulted in a loss of $10 million recorded to “Other comprehensive loss” and a combined federal and state deferred tax asset of $1 million. At December 31, 2017, based on the funded status of Conrail’s pension plans, we increased our proportional investment in Conrail by $19 million. This resulted in income of $17 million recorded to “Other comprehensive income” and a combined federal and state deferred tax liability of $2 million. At December 31, 2018, the difference between our investment in Conrail and our share of Conrail’s underlying net equity was $511 million. Our equity in the earnings of Conrail, net of amortization, included in “Purchased services and rents” was $55 million for 2018, $75 million for 2017 (including $33 million related to the enactment of tax reform – see Note 4), and $47 million for 2016. Equity in earnings are included in the “Other – net” line item within operating activities in the Consolidated Statements of Cash Flows. CRC owns and operates certain properties (the Shared Assets Areas) for the joint and exclusive benefit of NSR and CSX Transportation, Inc. (CSXT). The costs of operating the Shared Assets Areas are borne by NSR and CSXT based on usage. In addition, NSR and CSXT pay CRC a fee for access to the Shared Assets Areas. “Purchased services and rents” and “Fuel” include expenses payable to CRC for operation of the Shared Assets Areas totaling $150 million in 2018, $141 million in 2017, and $151 million in 2016. Future payments for access fees due to CRC under the Shared Assets Areas agreements are as follows: $38 million in each of 2019 through 2023 and $16 million thereafter. We provide certain general and administrative support functions to Conrail, the fees for which are billed in accordance with several service-provider arrangements and approximate $7 million annually. “Accounts payable” includes $202 million at December 31, 2018, and $146 million at December 31, 2017, due to Conrail for the operation of the Shared Assets Areas. “Other liabilities” includes $280 million at both December 31, 2018 and 2017 for long-term advances from Conrail, maturing in 2044, that bear interest at an average rate of 2.9%. Investment in TTX NS and eight other North American railroads jointly own TTX Company (TTX). NS has a 19.65% ownership interest in TTX, a railcar pooling company that provides its owner-railroads with standardized fleets of intermodal, automotive, and general use railcars at stated rates. Amounts paid to TTX for use of equipment are included in “Purchased services and rents.” This amounted to $262 million, $237 million, and $229 million of expense, respectively, for the years ended December 31, 2018, 2017 and 2016. Our equity in the earnings of TTX, also included in “Purchased services and rents,” totaled $61 million for 2018, $158 million (including $115 million related to the enactment of tax reform – see Note 4) for 2017, and $26 million for 2016. |

Debt | Debt Debt with weighted average interest rates and maturities is presented below:
In February of 2018, we issued $500 million of 4.15% senior notes due 2048. In August of 2018, we issued $300 million of 3.65% senior notes due 2025, $400 million of 3.80% senior notes due 2028, $200 million of 4.15% senior notes due 2048, and $600 million of 5.10% senior notes due 2118. In June of 2018, we renewed our accounts receivable securitization program for a 364-day term expiring in May 2019. We also increased the program’s capacity from $350 million to $400 million. Under this facility NSR sells substantially all of its eligible third-party receivables to a subsidiary, which in turn may transfer beneficial interests in the receivables to various commercial paper vehicles. Amounts received under the facility are accounted for as borrowings. Under this facility, we received $50 million in 2018, and paid $150 million and $100 million during 2018 and 2017, respectively. We had no amounts outstanding under this program at December 31, 2018 and $100 million (at an average variable interest rate of 3.21%) at December 31, 2017, which is included within “Short-term debt.” At December 31, 2018 and 2017, the receivables included in “Accounts receivable – net” serving as collateral for these borrowings totaled $793 million and $751 million, respectively. Borrowings under this program are supported by our $750 million credit agreement. The “Cash, cash equivalents, and restricted cash” line item in the Consolidated Statements of Cash Flows includes restricted cash of $88 million at December 31, 2018 which reflects deposits held by a third-party bond agent as collateral for certain debt obligations maturing in 2019. The restricted cash balance is included as part of “Other current assets” on the Consolidated Balance Sheets. Credit Agreement and Debt Covenants We have in place and available a $750 million, five-year credit agreement which expires in May 2021 and provides for borrowings at prevailing rates and includes covenants. We had no amounts outstanding under this facility at December 31, 2018 and 2017, and we are in compliance with all of its covenants. |

Pensions And Other Postretirement Benefits | Pensions and Other Postretirement Benefits We have both funded and unfunded defined benefit pension plans covering principally salaried employees. We also provide specified health care and life insurance benefits to eligible retired employees; these plans can be amended or terminated at our option. Under our self-insured retiree health care plan, for those participants who are not Medicare-eligible, a defined percentage of health care expenses is covered for retired employees and their dependents, reduced by any deductibles, coinsurance, and, in some cases, coverage provided under other group insurance policies. Those participants who are Medicare-eligible are not covered under the self-insured retiree health care plan, but instead are provided with an employer-funded health reimbursement account which can be used for reimbursement of health insurance premiums or eligible out-of-pocket medical expenses. Pension and Other Postretirement Benefit Obligations and Plan Assets
Our accumulated benefit obligation for our defined benefit pension plans is $2.2 billion and $2.3 billion at December 31, 2018 and December 31, 2017, respectively. Our unfunded pension plans, included above, which in all cases have no assets, had projected benefit obligations of $296 million and $313 million at December 31, 2018 and December 31, 2017, respectively, and had accumulated benefit obligations of $263 million and $267 million at December 31, 2018 and December 31, 2017, respectively. Pension and Other Postretirement Benefit Cost Components
Other Changes in Plan Assets and Benefit Obligations Recognized in Other Comprehensive Income
Net actuarial losses arising during the year for pension and other postretirement benefits were due primarily to lower actual returns on plan assets, partially offset by an increase in discount rates. The estimated net losses for the pension plans that will be amortized from accumulated other comprehensive loss into net periodic cost over the next year are $44 million. The estimated prior service benefit for the other postretirement benefit plans that will be amortized from accumulated other comprehensive loss into net periodic benefit over the next year is $24 million. Pension and Other Postretirement Benefits Assumptions Costs for pension and other postretirement benefits are determined based on actuarial valuations that reflect appropriate assumptions as of the measurement date, ordinarily the beginning of each year. The funded status of the plans is determined using appropriate assumptions as of each year end. A summary of the major assumptions follows:
To determine the discount rates used to measure our benefit obligations, we utilize analyses in which the projected annual cash flows from the pension and other postretirement benefit plans were matched with yield curves based on an appropriate universe of high-quality corporate bonds. We use the results of the yield curve analyses to select the discount rates that match the payment streams of the benefits in these plans. We use a spot rate approach to estimate the service cost and interest cost components of net periodic benefit cost for our pension and other postretirement benefit plans. Health Care Cost Trend Assumptions For measurement purposes at December 31, 2018, increases in the per capita cost of pre-Medicare covered health care benefits were assumed to be 6.5% for 2019. It is assumed the rate will decrease gradually to an ultimate rate of 5.0% for 2025 and remain at that level thereafter. Assumed health care cost trend rates affect the amounts reported in the consolidated financial statements. To illustrate, a one-percentage point change in the assumed health care cost trend would have the following effects:
Asset Management Eleven investment firms manage our defined benefit pension plans’ assets under investment guidelines approved by our Benefits Investment Committee that is comprised of members of our management. Investments are restricted to domestic and international equity securities, domestic and international fixed income securities, and unleveraged exchange-traded options and financial futures. Limitations restrict investment concentration and use of certain derivative investments. The target asset allocation for equity is 75% of the pension plans’ assets. Fixed income investments must consist predominantly of securities rated investment grade or higher. Equity investments must be in liquid securities listed on national exchanges. No investment is permitted in our securities (except through commingled pension trust funds). Our pension plans’ weighted average asset allocations, by asset category, were as follows:
The other postretirement benefit plan assets consist primarily of trust-owned variable life insurance policies with an asset allocation at December 31, 2018 of 64% in equity securities and 36% in debt securities compared with 67% in equity securities and 33% in debt securities at December 31, 2017. The target asset allocation for equity is between 50% and 75% of the plan’s assets. The plans’ assumed future returns are based principally on the asset allocations and historical returns for the plans’ asset classes determined from both actual plan returns and, over longer time periods, expected market returns for those asset classes. For 2019, we assume an 8.25% return on pension plan assets. Fair Value of Plan Assets Following is a description of the valuation methodologies used for pension plan assets measured at fair value. Common stock: Shares held by the plan at year end are valued at the official closing price as defined by the exchange or at the most recent trade price of a security at the close of the active market. Common collective trusts: The readily determinable fair value is based on the published fair value per unit of the trusts. The common collective trusts hold equity securities, fixed income securities and cash and cash equivalents. Fixed income securities: Valued based on quotes received from independent pricing services or at an estimated price at which a dealer would pay for a security at year end using observable market-based inputs. Commingled funds: The readily determinable fair value is based on the published fair value per unit of the funds. The commingled funds hold equity securities. Cash and cash equivalents: Short-term bills or notes are valued at an estimated price at which a dealer would pay for the security at year end using observable market-based inputs; money market funds are valued at the closing price reported on the active market on which the funds are traded. The following table sets forth the pension plans’ assets by valuation technique level, within the fair value hierarchy (there were no level 3 valued assets).
Following is a description of the valuation methodologies used for other postretirement benefit plan assets measured at fair value. Trust-owned life insurance: Valued at our share of the net assets of trust-owned life insurance issued by a major insurance company. The underlying investments of that trust consist of a U.S. stock account and a U.S. bond account but may retain cash at times as well. The U.S. stock account and U.S. bond account are valued based on readily determinable fair values. The other postretirement benefit plan assets consisted of trust-owned life insurance with fair values of $158 million and $201 million at December 31, 2018 and December 31, 2017, respectively, and are valued under level 2 of the fair value hierarchy. There were no level 1 or level 3 valued assets. Contributions and Estimated Future Benefit Payments In 2019, we expect to contribute approximately $18 million to our unfunded pension plans for payments to pensioners and approximately $41 million to our other postretirement benefit plans for retiree health and death benefits. We do not expect to contribute to our funded pension plan in 2019. Benefit payments, which reflect expected future service, as appropriate, are expected to be paid as follows:
Other Postretirement Coverage Under collective bargaining agreements, Norfolk Southern and certain subsidiaries participate in a multi-employer benefit plan, which provides certain postretirement health care and life insurance benefits to eligible union employees. Premiums under this plan are expensed as incurred and totaled $35 million in 2018, $44 million in 2017, and $37 million in 2016. Section 401(k) Plans Norfolk Southern and certain subsidiaries provide Section 401(k) savings plans for employees. Under the plans, we match a portion of employee contributions, subject to applicable limitations. Our matching contributions, recorded as an expense, under these plans were $23 million in both 2018 and 2017 and $21 million in 2016. |

Stock-Based Compensation | Stock-Based Compensation Under the stockholder-approved Long-Term Incentive Plan (LTIP), the Compensation Committee (Committee), which is made up of nonemployee members of the Board of Directors, or the Chief Executive Officer (when delegated authority by such Committee), may grant stock options, stock appreciation rights (SARs), restricted stock units (RSUs), restricted shares, performance share units (PSUs), and performance shares, up to a maximum of 104,125,000 shares of our Common Stock, of which 8,644,108 remain available for future grants as of December 31, 2018. The number of shares remaining for issuance under the LTIP is reduced (i) by 1 for each award granted as a stock option or stock-settled SAR, or (ii) by 1.61 for an award made in the form other than a stock option or stock-settled SAR. Under the Board-approved Thoroughbred Stock Option Plan (TSOP), the Committee may grant stock options up to a maximum of 6,000,000 shares of Common Stock. We use newly issued shares to satisfy any exercises and awards under the LTIP and the TSOP. The LTIP also permits the payment, on a current or a deferred basis and in cash or in stock, of dividend equivalents on shares of Common Stock covered by stock options, RSUs, or PSUs in an amount commensurate with regular quarterly dividends paid on Common Stock. With respect to stock options, if employment of the participant is terminated for any reason, including retirement, disability, or death, we have no further obligation to make any dividend equivalent payments. Regarding RSUs, we have no further obligation to make any dividend equivalent payments unless employment of the participant is terminated as a result of qualifying retirement or disability. Should an employee terminate employment, they are not required to forfeit dividend equivalent payments already received. Outstanding PSUs do not receive dividend equivalent payments. The Committee granted stock options, RSUs and PSUs pursuant to the LTIP and granted stock options pursuant to the TSOP for the last three years as follows:
Beginning in 2018, recipients of certain RSUs and PSUs pursuant to the LTIP who retire prior to October 1st will forfeit awards received in the current year. Receipt of certain LTIP awards is contingent on the recipient having executed a non-compete agreement with the company. We account for our grants of stock options, RSUs, PSUs, and dividend equivalent payments in accordance with FASB ASC 718, “Compensation - Stock Compensation.” Accordingly, all awards result in charges to net income while dividend equivalent payments, which are all related to equity classified awards, are charged to retained income. Compensation cost for the awards is recognized on a straight-line basis over the requisite service period for the entire award. Related compensation costs and tax benefits during the year were:
Stock Options Option exercise prices will be at least the higher of (i) the average of the high and low prices at which Common Stock is traded on the grant date, or (ii) the closing price of Common Stock on the grant date. All options are subject to a vesting period of at least one year, and the term of the option will not exceed ten years. Holders of the 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 the TSOP options. For all years, options granted under the LTIP and the TSOP may not be exercised prior to the fourth and third anniversaries of the date of grant, respectively, or if the optionee retires or dies before that anniversary date, may not be exercised before the later of one year after the grant date or the date of the optionee’s retirement or death. The fair value of each option awarded in 2018 was measured on the date of grant using the Black-Scholes valuation model. The fair value of each option awarded in 2017 and 2016 was measured on the date of grant using a binomial lattice-based option valuation model. Expected volatility is based on implied volatility from traded options on, and historical volatility of, Common Stock. Historical data is used to estimate option exercises and employee terminations within the valuation model. For the 2018 grant year, historical exercise data is used to estimate the average expected option term. For the 2017 and 2016 grant years, the average expected option term is derived from the output of the valuation model and represents the period of time that all options granted are expected to be outstanding, including the branches of the model that result in options expiring unexercised. The average risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. A dividend yield of zero was used for the LTIP options during the vesting period. For 2018, 2017, and 2016, a dividend yield of 1.94%, 2.04%, and 3.37%, respectively, was used for all vested LTIP options and all TSOP options. The assumptions for the LTIP and TSOP grants for the last three years are shown in the following table:
A summary of changes in stock options is presented below:
The aggregate intrinsic value of options outstanding at December 31, 2018 was $215 million with a weighted average remaining contractual term of 5.7 years. Of these options outstanding, 1,908,864 were exercisable and had an aggregate intrinsic value of $175 million with a weighted average exercise price of $57.81 and a weighted average remaining contractual term of 3.0 years. The following table provides information related to options exercised for the last three years:
At December 31, 2018, total unrecognized compensation related to options granted under the LTIP and the TSOP was $5 million, and is expected to be recognized over a weighted-average period of approximately 1.6 years. Restricted Stock Units RSUs granted in 2018 primarily have a four-year ratable restriction period and will be settled through the issuance of shares of Common Stock. RSUs granted in 2017 and 2016 have a five-year restriction period and will also be settled through the issuance of shares of Common Stock. Certain RSU grants include cash dividend equivalent payments during the restriction period in an amount equal to regular quarterly dividends paid on Common Stock.
A summary of changes in RSUs is presented below:
At December 31, 2018, total unrecognized compensation related to RSUs was $17 million, and is expected to be recognized over a weighted-average period of approximately 2.9 years. Performance Share Units PSUs provide for awards based on the achievement of certain predetermined corporate performance goals at the end of a three-year cycle and are settled through the issuance of shares of Common Stock. All PSUs will earn out based on the achievement of performance conditions and some will also earn out based on a market condition. The market condition fair value was measured on the date of grant using a Monte Carlo simulation model.

Earnings Per Share | Earnings Per Share The following table sets forth the calculation of basic and diluted earnings per share:
In each year, dividend equivalent payments were made to holders of stock options and RSUs. For purposes of computing basic earnings per share, dividend equivalent payments made to holders of stock options and RSUs were deducted from net income to determine income available to common stockholders. For purposes of computing diluted earnings per share, we evaluate on a grant-by-grant basis those stock options and RSUs receiving dividend equivalent payments under the two-class and treasury stock methods to determine which method is more dilutive for each grant. For those grants for which the two-class method was more dilutive, net income was reduced by dividend equivalent payments to determine income available to common stockholders. The dilution calculations exclude options having exercise prices exceeding the average market price of Common Stock of zero, 0.2 million, and 1.3 million for the years ended December 31, 2018, 2017 and 2016, respectively. |

Commitments and Contingencies Disclosure [Abstract] | |
Commitments And Contingencies | Commitments and Contingencies Lawsuits We and/or certain subsidiaries are defendants in numerous lawsuits and other claims relating principally to railroad operations. When we conclude 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 our 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 become known. In 2007, various antitrust class actions filed against us and other Class I railroads in various Federal district courts regarding fuel surcharges were consolidated in the District of Columbia by the Judicial Panel on Multidistrict Litigation. In 2012, the court certified the case as a class action. The defendant railroads appealed this certification, and the Court of Appeals for the District of Columbia vacated the District Court’s decision and remanded the case for further consideration. On October 10, 2017, the District Court denied class certification; the findings are subject to appeal. We believe the allegations in the complaints are without merit and intend to vigorously defend the cases. We do not believe the outcome of these proceedings will have a material effect on our financial position, results of operations, or liquidity. 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 our personal injury liability and determining the amount to accrue with respect to such claims during the year, we utilize studies prepared by an independent consulting actuarial firm. Job-related personal injury and occupational claims are subject to FELA, which is applicable only to railroads. FELA’s fault-based tort 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 our 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, we record a liability when the expected loss for the claim is both probable and reasonably estimable. Employee personal injury claims – The largest component of casualties and other claims expense is employee personal injury costs. The independent actuarial firm engaged by us provides quarterly studies to aid in valuing our employee personal injury liability and estimating personal injury expense. The actuarial firm studies our historical patterns of reserving for claims and subsequent settlements, taking into account relevant outside influences. The actuarial firm uses the results of these analyses to estimate the ultimate amount of liability. We adjust the liability quarterly based upon our assessment and the results of the study. Our estimate of the liability is subject to inherent limitation given the difficulty of predicting future events such as jury decisions, court interpretations, or legislative changes. As a result, actual claim settlements may vary from the estimated liability recorded. Occupational claims – Occupational claims include injuries and illnesses alleged to be caused by exposures which occur over time as opposed to injuries or illnesses caused by a specific accident or event. Types of occupational claims commonly seen allege exposure to asbestos and other claimed toxic substances resulting in respiratory diseases or cancer, exposure to repetitive motion resulting in various musculoskeletal disorders, and exposure to excessive noise resulting in hearing loss. 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 our history of claim filings, severity, payments, and other pertinent facts. The liability is dependent upon judgments we make as to the specific case reserves as well as judgments of the actuarial firm in the quarterly 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 our experience. We adjust the liability quarterly based upon our 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 – We record a liability for third-party claims including those for highway crossing accidents, trespasser and other injuries, automobile liability, property damage, and lading damage. The actuarial firm assists us with the calculation of potential liability for third-party claims, except lading damage, based upon our experience including the number and timing of incidents, amount of payments, settlement rates, number of open claims, and legal defenses. We adjust the liability quarterly based upon our 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 We are subject to various jurisdictions’ environmental laws and regulations. We record a liability where such liability or loss is probable and reasonably estimable. Environmental specialists regularly participate in ongoing evaluations of all known sites and in determining any necessary adjustments to liability estimates. Our Consolidated Balance Sheets include liabilities for environmental exposures of $55 million at December 31, 2018, and $58 million at December 31, 2017, of which $15 million is classified as a current liability at the end of both 2018 and 2017. At December 31, 2018, the liability represents our estimates of the probable cleanup, investigation, and remediation costs based on available information at 114 known locations and projects compared with 127 locations and projects at December 31, 2017. At December 31, 2018, fifteen sites accounted for $37 million of the liability, and no individual site was considered to be material. We anticipate that much of this liability will be paid out over five years; however, some costs will be paid out over a longer period. At eleven locations, one or more of our 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. We calculate our estimated liability for these sites based on facts and legal defenses applicable to each site and not solely on the basis of the potential for joint liability. With respect to known environmental sites (whether identified by us or by the Environmental Protection Agency or comparable state authorities), estimates of our ultimate potential financial exposure for a given site or in the aggregate for all such sites can change over time because of the widely varying costs of currently available cleanup techniques, unpredictable contaminant recovery and reduction rates associated with available cleanup technologies, the likely development of new cleanup 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 we transport, particularly those classified as hazardous materials, pose special risks that we work diligently to reduce. In addition, several of our 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 that are latent or undisclosed may exist on these properties, there can be no assurance that we 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 our assessment of the facts and circumstances now known, we believe we have recorded the probable and reasonably estimable costs for dealing with those environmental matters of which we are aware. Further, we believe that it is unlikely that any known matters, either individually or in the aggregate, will have a material adverse effect on our financial position, results of operations, or liquidity. Insurance We obtain on behalf of ourself and our subsidiaries insurance for potential losses for third-party liability and first-party property damages. We are currently self-insured up to $50 million and above $1.1 billion ($1.5 billion for specific perils) per occurrence and/or policy year for bodily injury and property damage to third parties and up to $25 million and above $200 million per occurrence and/or policy year for property owned by us or in our care, custody, or control. Purchase Commitments At December 31, 2018, we had outstanding purchase commitments totaling approximately $1.2 billion for locomotives, track material, long-term service contracts, track and yard expansion projects in connection with our capital programs as well as freight cars and containers through 2023. Change-In-Control Arrangements We have compensation agreements with certain officers and key employees that become operative only upon a change in control of Norfolk Southern, as defined in those agreements. The agreements provide generally for payments based on compensation at the time of a covered individual’s involuntary or other specified termination and for certain other benefits. Indemnifications In a number of instances, we have agreed to indemnify lenders for additional costs they may bear as a result of certain changes in laws or regulations applicable to their loans. Such changes may include impositions or modifications with respect to taxes, duties, reserves, liquidity, capital adequacy, special deposits, and similar requirements relating to extensions of credit by, deposits with, or the assets or liabilities of such lenders. The nature and timing of changes in laws or regulations applicable to our financings are inherently unpredictable, and therefore our exposure in connection with the foregoing indemnifications cannot be quantified. No liability has been recorded related to these indemnifications. |

Summary Of Significant Accounting Policies (Policy) |
12 Months Ended | ||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Dec. 31, 2018 | |||||||||||||||||||||
Accounting Policies [Abstract] | |||||||||||||||||||||
Description of Business | Description of Business Norfolk Southern Corporation is a Virginia-based holding company engaged principally in the rail transportation business, operating approximately 19,500 route miles primarily in the East and Midwest. These consolidated financial statements include Norfolk Southern and its majority-owned and controlled subsidiaries (collectively, NS, we, us, and our). Norfolk Southern’s major subsidiary is NSR. All significant intercompany balances and transactions have been eliminated in consolidation. NSR and its railroad subsidiaries transport raw materials, intermediate products, and finished goods classified in the following commodity groups (percent of total railway operating revenues in 2018): intermodal (25%); coal (16%); chemicals (16%); agriculture, consumer products, and government (14%); metals and construction (13%); automotive (9%); and, paper, clay, and forest products (7%). Although most of our customers are domestic, ultimate points of origination or destination for some of the products transported (particularly coal bound for export and some intermodal containers) may be outside the U.S. Approximately 80% of our railroad employees are covered by collective bargaining agreements with various labor unions. |
||||||||||||||||||||
Use of Estimates | Use of Estimates The preparation of financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We periodically review our estimates, including those related to the recoverability and useful lives of assets, as well as liabilities for litigation, environmental remediation, casualty claims, income taxes and pension and other postretirement benefits. Changes in facts and circumstances may result in revised estimates. |
||||||||||||||||||||
Revenue Recognition | Revenue Recognition Transportation revenue is recognized proportionally as a shipment moves from origin to destination, and related expenses are recognized as incurred. Certain of our contract refunds (which are primarily volume-based incentives) are recorded as a reduction to revenues on the basis of management’s best estimate of projected liability, which is based on historical activity, current shipment counts and expectation of future activity. Switching, demurrage and other incidental service revenues are recognized at a point in time when the services are performed or as contractual obligations are met. |
||||||||||||||||||||
Cash Equivalents | Cash Equivalents “Cash equivalents” are highly liquid investments purchased three months or less from maturity. |
||||||||||||||||||||
Allowance For Doubtful Accounts | Allowance for Doubtful Accounts Our allowance for doubtful accounts was $7 million at both December 31, 2018 and 2017. To determine our allowance for doubtful accounts, we evaluate historical loss experience (which has not been significant), the characteristics of current accounts, and general economic conditions and trends. |
||||||||||||||||||||
Materials And Supplies | Materials and Supplies “Materials and supplies,” consisting mainly of items for maintenance of property and equipment, are stated at the lower of average cost or net realizable value. The cost of materials and supplies expected to be used in property additions or improvements is included in “Properties.” |
||||||||||||||||||||
Investments | Investments Investments in entities over which we have the ability to exercise significant influence but do not control the entity are accounted for using the equity method, whereby the investment is carried at the cost of the acquisition plus our equity in undistributed earnings or losses since acquisition. |
||||||||||||||||||||
Properties | Properties “Properties” are stated principally at cost and are depreciated using the group method whereby assets with similar characteristics, use, and expected lives are grouped together in asset classes and depreciated using a composite depreciation rate. This methodology treats each asset class as a pool of resources, not as singular items. We use approximately 75 depreciable asset classes. “Depreciation” in the Consolidated Statements of Cash Flows includes both depreciation and depletion on operating and nonoperating properties. Depreciation expense is based on our assumptions concerning expected service lives of our properties as well as the expected net salvage that will be received upon their retirement. In developing these assumptions, we utilize periodic depreciation studies that are performed by an independent outside firm of consulting engineers and approved by the STB. Our depreciation studies are conducted about every three years for equipment and every six years for track assets and other roadway property. The frequency of these studies is consistent with guidelines established by the STB. We adjust our rates based on the results of these studies and implement the changes prospectively. The studies may also indicate that the recorded amount of accumulated depreciation is deficient (or in excess) of the amount indicated by the study. Any such deficiency (or excess) is amortized as a component of depreciation expense over the remaining service lives of the affected class of property, as determined by the study. Key factors that are considered in developing average service life and salvage estimates include:
The composite depreciation rate for rail in high density corridors is derived based on consideration of annual gross tons as compared to the total or ultimate capacity of rail in these corridors. Our experience has shown that traffic density is a leading factor in the determination of the expected service life of rail in high density corridors. In developing the respective depreciation rate, consideration is also given to several rail characteristics including age, weight, condition (new or second-hand) and type (curved or straight). We capitalize interest on major projects during the period of their construction. Expenditures, including those on leased assets, that extend an asset’s useful life or increase its utility are capitalized. Expenditures capitalized include those that are directly related to a capital project and may include materials, labor and equipment, in addition to an allocable portion of indirect costs that relate to a capital project. A significant portion of annual capital spending relates to the replacement of self-constructed assets. Removal activities occur in conjunction with replacement and are estimated based on the average percentage of time employees replacing assets spend on removal functions. Costs related to repairs and maintenance activities that do not extend an asset’s useful life or increase its utility are expensed when such repairs are performed. When depreciable operating road and equipment assets are sold or retired in the ordinary course of business, the cost of the assets, net of sale proceeds or salvage, is charged to accumulated depreciation, and no gain or loss is recognized in earnings. Actual historical cost values are retired when available, such as with most equipment assets. The use of estimates in recording the retirement of certain roadway assets is necessary based on the impracticality of tracking individual asset costs. When retiring rail, ties and ballast, we use statistical curves that indicate the relative distribution of the age of the assets retired. The historical cost of other roadway assets is estimated using a combination of inflation indices specific to the rail industry and those published by the U.S. Bureau of Labor Statistics. The indices are applied to the replacement value based on the age of the retired assets. These indices are used because they closely correlate with the costs of roadway assets. Gains and losses on disposal of operating land are included in “Materials and other” expenses. Gains and losses on disposal of nonoperating land and nonrail assets are included in “Other income – net” since such income is not a product of our railroad operations. A retirement is considered abnormal if it does not occur in the ordinary course of business, if it relates to disposition of a large segment of an asset class and if the retirement varies significantly from the retirement profile identified through our depreciation studies, which inherently consider the impact of normal retirements on expected service lives and depreciation rates. Gains or losses from abnormal retirements would be recognized in income from railway operations. We review the carrying amount of properties whenever events or changes in circumstances indicate that such carrying amount may not be recoverable based on future undiscounted cash flows. Assets that are deemed impaired as a result of such review are recorded at the lower of carrying amount or fair value. |

This standard replaced most existing revenue recognition guidance in GAAP and requires entities to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. A performance obligation is defined as a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. We adopted the provisions of this standard on January 1, 2018, using the modified retrospective method. There was no cumulative effect of initially applying the standard, nor is there any material difference in revenue for the year ended December 31, 2018, as compared with GAAP that was in effect prior to January 1, 2018. In March 2017, the FASB issued ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” This update requires segregation of net benefit costs between operating and nonoperating expenses and requires retrospective application. We adopted the standard on January 1, 2018. Under the new standard, only the service cost component of defined benefit pension cost and postretirement benefit cost are reported within “Compensation and benefits” and all other components of net benefit cost are presented in “Other income – net” on the Consolidated Statements of Income, whereas under the previous standard all components were included in “Compensation and benefits.” The retrospective application resulted in an increase to “Compensation and benefits” expense and an offsetting increase to “Other income – net” on the Consolidated Statements of Income of $64 million and $65 million for the years ended December 31, 2017 and December 31, 2016, respectively, with no impact on “Net income.” In February 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income.” This update is intended to reclassify the stranded tax effects resulting from tax reform from accumulated other comprehensive income (AOCI) to retained earnings. The amount of the reclassification is the difference between the amount initially charged or credited directly to other comprehensive income at the previously enacted U.S. federal corporate income tax rate that remains in AOCI and the amount that would have been charged or credited directly to other comprehensive income using the newly enacted U.S. federal corporate income tax rate. In the first quarter of 2018, we adopted the provisions of ASU 2018-02 resulting in an increase to “Accumulated other comprehensive loss” of $88 million and a corresponding increase to “Retained income,” with no impact on “Total stockholders’ equity.” In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” and subsequent amendments, which replaced existing lease guidance in GAAP and requires lessees to recognize right-of-use (ROU) assets and lease liabilities on the balance sheet for leases greater than twelve months and disclose key information about leasing arrangements. We adopted the standard on January 1, 2019 using the modified retrospective method and used the effective date as our date of initial application. Financial information will not be updated and the disclosures required under the new standard will not be provided for dates and periods before January 1, 2019. The new standard provides a number of optional practical expedients for transition. We elected the package of practical expedients under the transition guidance which permits us not to reassess under the new standards our prior conclusions for lease identification and lease classification on expired or existing contracts and whether initial direct costs previously capitalized would qualify for capitalization under ASC 842. We also elected the practical expedient related to land easements, allowing us to not reasses our current accounting treatment for existing agreements on land easements, which are not accounted for as leases. We did not elect the hindsight practical expedient to determine the reasonably certain lease term for existing leases. The new standard also provides practical expedients and recognition exemptions for an entity’s ongoing accounting policy elections. We elected the short-term lease recognition exemption for all leases that qualify. This means, for those leases that qualify, we will not recognize ROU assets or lease liabilities. We also elected the practical expedient not to separate lease and non-lease components for all of our leases. We expect that adoption of the standard will result in recognition of lease liabilities of approximately $600 million as of January 1, 2019, with corresponding ROU assets of the same amount based on the present value of the remaining minimum rental payments under current leasing standards for existing operating leases. There will be no adjustment to “Retained income” on adoption. In June 2016, the FASB issued ASU 2016-13, “Credit Losses - Measurement of Credit Losses on Financial Instruments,” which replaces the current incurred loss impairment method with a method that reflects expected credit losses. The new standard is effective as of January 1, 2020, and early adoption is permitted as of January 1, 2019. Because credit losses associated from our trade receivables have historically been insignificant, we do not expect this standard to have a material effect on our financial statements. We will not adopt the standard early. |
