NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. Accounting Policies and Interim Results

The Consolidated Financial Statements should be read in conjunction with BNSF Railway Company’s Annual Report on Form 10-K for the year ended December 31, 2014, including the financial statements and notes thereto. The Consolidated Financial Statements include the accounts of BNSF Railway Company and its majority-owned subsidiaries, all of which are separate legal entities (collectively BNSF Railway or the Company). BNSF Railway is a wholly-owned subsidiary of Burlington Northern Santa Fe, LLC (BNSF), and is the principal operating subsidiary of BNSF. All intercompany accounts and transactions have been eliminated.

Subsequent to December 31, 2014, BNSF Railway added a significant accounting policy for investments. Investments in fixed maturity securities and equity securities are classified at the acquisition date and the classification is re-evaluated at each balance sheet date. Trading securities are investments acquired with the intent to sell in the near term and are carried at fair value. All investments currently held are classified as trading securities and net unrealized gains or losses are recorded in income.

On February 12, 2010, Berkshire Hathaway Inc., a Delaware corporation (Berkshire), acquired 100% of the outstanding shares of Burlington Northern Santa Fe Corporation common stock that it did not already own. The acquisition was completed through the merger (Merger) of a Berkshire wholly-owned merger subsidiary and Burlington Northern Santa Fe Corporation with the surviving entity renamed Burlington Northern Santa Fe, LLC. Earnings per share data has not been presented because BNSF has not issued stock or membership interests to the public.

The results of operations for any interim period are not necessarily indicative of the results of operations to be expected for the entire year. In the opinion of management, the unaudited financial statements reflect all adjustments (consisting of only normal recurring adjustments, except as disclosed) necessary for a fair statement of BNSF Railway’s consolidated financial position as of March 31, 2015, and the results of operations for the three months ended March 31, 2015 and 2014.

2. Accounts Receivable, Net

Accounts receivable, net consists of freight and other receivables, reduced by an allowance for bill adjustments and uncollectible accounts, based upon expected collectibility. At March 31, 2015, and December 31, 2014, $55 million of such allowances had been recorded.

At March 31, 2015 and December 31, 2014, $48 million and $33 million, respectively, of accounts receivable were greater than 90 days old.

3. Investments

BNSF Railway holds investments which are classified as trading securities and included in Other Assets on the balance sheet. The following table summarizes the fair value of investments held as of March 31, 2015 and December 31, 2014 (in millions):

	March 31, 2015		December 31, 2014
Debt securities	$	32	$	—
Equity securities	13		—
Total	$	45	$	—

Prior to the quarter-ended March 31, 2015, all investments were primarily held in cash and cash equivalents.

The fair value measurements of BNSF Railway’s debt securities are based on Level 2 inputs and equity securities are based on Level 1 inputs, using a market approach. Unrealized gains and losses recognized in earnings for the period ended March 31, 2015 were less than $1 million.

4. Other Intangible Assets and Liabilities

Intangible assets and liabilities were as follows (in millions):

	As of March 31, 2015				As of December 31, 2014
	Gross Carrying Amount		Accumulated Amortization		Gross Carrying Amount		Accumulated Amortization
Intangible assets	$	635	$	160	$	2,017	$	1,511
Intangible liabilities	$	1,403	$	655	$	2,056	$	1,274

As of March 31, 2015, intangible assets primarily consisted of franchise and customer assets. At December 31, 2014, intangible assets also included internally developed software that became fully amortized in the first quarter of 2015. Intangible liabilities primarily consisted of customer and shortline contracts which were in an unfavorable position at the date of Merger.

Amortizable intangible assets and liabilities are amortized based on the estimated pattern in which the economic benefits are expected to be consumed or on a straight-line basis over their estimated economic lives.

Amortization of intangible assets and liabilities was as follows (in millions):

	Three Months Ended March 31,
	2015		2014
Amortization of intangible assets	$	31	$	77
Amortization of intangible liabilities	$	34	$	44

Amortization of intangible assets and liabilities for the next five years is expected to approximate the following (in millions):

	Amortization of intangible assets		Amortization of intangible liabilities
Remainder of 2015	$	23	$	81
2016	$	31	$	101
2017	$	31	$	96

5. Other Assets

In July 2010, the Company entered into a low-income housing partnership (the Partnership) as the limited partner, holding a 99.9% interest in the Partnership. The Partnership is a variable interest entity (VIE), with the purpose of developing and operating low-income housing rental properties. Recovery of the Company’s investment is accomplished through the utilization of low-income housing tax credits and the tax benefits of Partnership losses. The general partner, who holds a 0.1% interest in the Partnership, is an unrelated third party and is responsible for controlling and managing the business and financial operation of the Partnership. As the Company does not have the power to direct the activities that most significantly impact the Partnership’s economic performance, the Company is not the primary beneficiary and therefore, does not consolidate the Partnership. As of March 31, 2015 and December 31, 2014, the assets of the unconsolidated Partnership totaled approximately $320 million and $330 million, respectively. The Company does not provide financial support to the Partnership that it was not previously contractually obligated to provide.

The Company has accounted for its investment in the Partnership using the effective yield method. The risk of loss of the Company's investment in the Partnership is considered low as an affiliate of the general partner has provided certain guarantees of tax credits and minimum annual returns. For the three months ended March 31, 2015 and 2014, the Company recognized a reduction to income tax expense of $9 million and $10 million, respectively. The Company’s maximum exposure to loss related to the Partnership is the unamortized investment balance. The following table provides information related to this Partnership (in millions):

	March 31, 2015		December 31, 2014
Unamortized investment balance classified as Other Assets	$	298	$	314
Remaining commitment classified as Other Liabilities	$	18	$	18
Maximum exposure to loss	$	298	$	314

The remaining commitment of $18 million is expected to be paid in 2015.

6. Debt

Fair Value of Debt Instruments

At March 31, 2015, and December 31, 2014, the fair value of BNSF Railway's debt, excluding capital leases, was $735 million and $738 million, respectively, while the book value, which also excludes capital leases and the associated unamortized fair value adjustment under acquisition method accounting related to capital leases, was $635 million and $651 million, respectively. The fair value of BNSF Railway's debt is primarily based on market value price models using observable market-based data for the same or similar issues, or on the estimated rates that would be offered to BNSF Railway for debt of the same remaining maturities (Level 2 inputs).

Guarantees

As of March 31, 2015, BNSF Railway has not been called upon to perform under the guarantees specifically disclosed in this footnote and does not anticipate a significant performance risk in the foreseeable future.

Debt and other obligations of non-consolidated entities guaranteed by the Company as of March 31, 2015, were as follows (dollars in millions):

	Guarantees
	BNSF Railway Ownership Percentage		Principal Amount Guaranteed		Maximum Future Payments		Maximum Recourse Amounta		Remaining Term (in years)	Capitalized Obligations
Kinder Morgan Energy Partners, L.P.	0.5	%	$	190	$	190	$	—	Termination of Ownership	$	2	b
Chevron Phillips Chemical Company LP	—	%	N/Ad		N/Ad		N/Ad		2	$	4	c

^a  Reflects the maximum amount the Company could recover from a third party other than the counterparty.

^b  Reflects capitalized obligations that are recorded on the Company’s Consolidated Balance Sheet.

^c  Reflects the asset and corresponding liability for the fair value of these guarantees required by authoritative accounting guidance related to guarantees.

^d  There is no cap to the liability that can be sought from BNSF Railway for BNSF Railway’s negligence or the negligence of the indemnified party. However, BNSF Railway could receive reimbursement from certain insurance policies if the liability exceeds a certain amount.

Kinder Morgan Energy Partners, L.P.

Santa Fe Pacific Pipelines, Inc., an indirect, wholly-owned subsidiary of BNSF Railway, has a guarantee in connection with its remaining special limited partnership interest in Santa Fe Pacific Pipeline Partners, L.P. (SFPP), a subsidiary of Kinder Morgan Energy Partners, L.P., to be paid only upon default by the partnership. All obligations with respect to the guarantee will cease upon termination of ownership rights, which would occur upon a put notice issued by BNSF Railway or the exercise of the call rights by the general partners of SFPP.

Chevron Phillips Chemical Company LP

In 2007, BNSF Railway entered into an indemnity agreement with Chevron Phillips Chemical Company LP (Chevron Phillips), granting certain rights of indemnity from BNSF Railway, in order to facilitate access to a new storage facility. Under certain circumstances, payment under this obligation may be required in the event Chevron Phillips were to incur certain liabilities or other incremental costs resulting from trackage access.

11

BNSF RAILWAY COMPANY and SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) – (Continued)

Indemnities

In the ordinary course of business, BNSF Railway enters into agreements with third parties that include indemnification clauses. The Company believes that these clauses are generally customary for the types of agreements in which they are included. At times, these clauses may involve indemnification for the acts of the Company, its employees and agents, indemnification for another party’s acts, indemnification for future events, indemnification based upon a certain standard of performance, indemnification for liabilities arising out of the Company’s use of leased equipment or other property, or other types of indemnification. Despite the uncertainty whether events which would trigger the indemnification obligations would ever occur, the Company does not believe that these indemnity agreements will have a material adverse effect on the Company’s results of operations, financial position or liquidity. Additionally, the Company believes that, due to lack of historical payment experience, the fair value of indemnities cannot be estimated with any amount of certainty. However, the fair value of any such amount would be immaterial to the Consolidated Financial Statements. Agreements that reflect unique circumstances, particularly agreements that contain guarantees that indemnify for another party’s acts, are disclosed separately, if appropriate. Unless separately disclosed above, no fair value liability related to indemnities has been recorded in the Consolidated Financial Statements.

Variable Interest Entities - Leases

BNSF Railway has entered into various equipment lease transactions in which the structure of the lease contains VIEs. These VIEs were created solely for the lease transactions and have no other activities, assets or liabilities outside of the lease transactions. In some of the arrangements, BNSF Railway has the option to purchase some or all of the equipment at a fixed-price, thereby creating variable interests for BNSF Railway in the VIEs. The future minimum lease payments associated with the VIE leases were approximately $3 billion as of March 31, 2015.

In the event the leased equipment is destroyed, BNSF Railway is obligated to either replace the equipment or pay a fixed loss amount. The inclusion of the fixed loss amount is a standard clause within equipment lease arrangements. Historically, BNSF Railway has not incurred significant losses related to this clause. As such, it is not anticipated that the maximum exposure to loss would materially differ from the future minimum lease payments.

BNSF Railway does not provide financial support to the VIEs that it was not previously contractually obligated to provide.

BNSF Railway maintains and operates the equipment based on contractual obligations within the lease arrangements, which set specific guidelines consistent within the industry. As such, BNSF Railway has no control over activities that could materially impact the fair value of the leased equipment. BNSF Railway does not hold the power to direct the activities of the VIEs and therefore does not control the ongoing activities that have a significant impact on the economic performance of the VIEs. Additionally, BNSF Railway does not have the obligation to absorb losses of the VIEs or the right to receive benefits of the VIEs that could potentially be significant to the VIEs. Depending on market conditions, the fixed-price purchase options could potentially provide benefit to the Company; however, any benefits potentially received from a fixed-price purchase option are expected to be minimal. Based on these factors, BNSF Railway is not the primary beneficiary of the VIEs. As BNSF Railway is not the primary beneficiary and the VIE leases are classified as operating leases, there are no assets or liabilities related to the VIEs recorded in the Company's Consolidated Balance Sheet.

7. Commitments and Contingencies

Personal Injury

Personal injury claims, including asbestos claims and employee work-related injuries and third-party injuries (collectively, other personal injury), are a significant expense for the railroad industry. Personal injury claims by BNSF Railway employees are subject to the provisions of the Federal Employers’ Liability Act (FELA) rather than state workers’ compensation laws. FELA’s system of requiring the finding of fault, coupled with unscheduled awards and reliance on the jury system, contributed to increased expenses in past years. Other proceedings include claims by non-employees for punitive as well as compensatory damages. A few proceedings purport to be class actions. The variability present in settling these claims, including non-employee personal injury and matters in which punitive damages are alleged, could result in increased expenses in future years. BNSF Railway has implemented a number of safety programs designed to reduce the number of personal injuries as well as the associated claims and personal injury expense.

BNSF Railway records an undiscounted liability for personal injury claims when the expected loss is both probable and reasonably estimable. The liability and ultimate expense projections are estimated using standard actuarial methodologies. Liabilities recorded for unasserted personal injury claims are based on information currently available. Due to the inherent uncertainty involved in projecting future events such as the number of claims filed each year, developments in judicial and legislative standards and the average costs to settle projected claims, actual costs may differ from amounts recorded. BNSF Railway has obtained insurance coverage for certain claims, as discussed under the heading “BNSF Insurance Company.” Expense accruals and any required adjustments are classified as materials and other in the Consolidated Statements of Income.

Asbestos

The Company is party to a number of personal injury claims by employees and non-employees who may have been exposed to asbestos. The heaviest exposure for certain BNSF Railway employees was due to work conducted in and around the use of steam locomotive engines that were phased out between the years of 1950 and 1967. However, other types of exposures, including exposure from locomotive component parts and building materials, continued after 1967 until they were substantially eliminated at BNSF Railway by 1985.

BNSF Railway assesses its unasserted asbestos liability exposure on an annual basis during the third quarter. BNSF Railway determines its asbestos liability by estimating its exposed population, the number of claims likely to be filed, the number of claims that will likely require payment and the estimated cost per claim. Estimated filing and dismissal rates and average cost per claim are determined utilizing recent claim data and trends.

Throughout the year, BNSF Railway monitors actual experience against the number of forecasted claims and expected claim payments and will record adjustments to the Company’s estimates as necessary.

Based on BNSF Railway’s estimate of the potentially exposed employees and related mortality assumptions, it is anticipated that unasserted asbestos claims will continue to be filed through the year 2050. The Company recorded an amount for the full estimated filing period through 2050 because it had a relatively finite exposed population (former and current employees hired prior to 1985), which it was able to identify and reasonably estimate and about which it had obtained reliable demographic data (including age, hire date and occupation) derived from industry or BNSF Railway specific data that was the basis for the study. BNSF Railway projects that approximately 60, 80 and 95 percent of the future unasserted asbestos claims will be filed within the next 10, 15 and 25 years, respectively.

Other Personal Injury

BNSF Railway estimates its other personal injury liability claims and expense quarterly based on the covered population, activity levels and trends in frequency and the costs of covered injuries. Estimates include unasserted claims except for certain repetitive stress and other occupational trauma claims that allegedly result from prolonged repeated events or exposure. Such claims are estimated on an as-reported basis because the Company cannot estimate the range of reasonably possible loss due to other non-work related contributing causes of such injuries and the fact that continued exposure is required for the potential injury to manifest itself as a claim. BNSF Railway has not experienced any significant adverse trends related to these types of claims in recent years.

13

BNSF RAILWAY COMPANY and SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) – (Continued)

BNSF Railway monitors quarterly actual experience against the number of forecasted claims to be received, the forecasted number of claims closing with payment and expected claim payments. Adjustments to the Company’s estimates are recorded quarterly as necessary or more frequently as new events or revised estimates develop.

The following tables summarize the activity in the Company’s accrued obligations for asbestos and other personal injury matters (in millions):

	Three Months Ended March 31,
	2015			2014
Beginning balance	$	375		$	387
Accruals	18			18
Payments	(20		)	(19		)
Ending balance	$	373		$	386

At March 31, 2015, $80 million was included in current liabilities. Defense and processing costs, which are recorded on an as-reported basis, were not included in the recorded liability. The Company is primarily self-insured for personal injury claims.

Because of the uncertainty surrounding the ultimate outcome of personal injury claims, it is reasonably possible that future costs to settle personal injury claims may range from approximately $330 million to $440 million. However, BNSF Railway believes that the $373 million recorded at March 31, 2015 is the best estimate of the Company’s future obligation for the settlement of personal injury claims.

The amounts recorded by BNSF Railway for personal injury liabilities were based upon currently known facts. Future events, such as the number of new claims to be filed each year, the average cost of disposing of claims, as well as the numerous uncertainties surrounding personal injury litigation in the United States, could cause the actual costs to be higher or lower than projected.

14

BNSF RAILWAY COMPANY and SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) – (Continued)

Although the final outcome of personal injury matters cannot be predicted with certainty, considering among other things the meritorious legal defenses available and liabilities that have been recorded, it is the opinion of BNSF Railway that none of these items, when finally resolved, will have a material adverse effect on the Company’s financial position or liquidity. However, the occurrence of a number of these items in the same period could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

BNSF Insurance Company

Burlington Northern Santa Fe Insurance Company, Ltd. (BNSF IC), a wholly-owned subsidiary of BNSF, provides insurance coverage for certain risks, FELA claims, railroad protective and force account insurance claims and certain excess general liability and property coverage, and certain other claims which are subject to reinsurance. During the three months ended March 31, 2015 and 2014, BNSF IC wrote insurance coverage with premiums totaling $51 million and $45 million, respectively, for BNSF Railway, net of reimbursements from third parties. During this same time, BNSF Railway recognized $20 million and $21 million, respectively, in expense related to those premiums, which is classified as purchased services in the Consolidated Statements of Income. At March 31, 2015, unamortized premiums remaining on the Consolidated Balance Sheet were $38 million. During the three months ended March 31, 2015 and 2014, BNSF IC made claim payments totaling $180 million and $41 million, respectively, for settlement of covered claims. At March 31, 2015 and December 31, 2014, claims receivables from BNSF IC were $5 million and $10 million, respectively.

Environmental

The Company’s operations, as well as those of its competitors, are subject to extensive federal, state and local environmental regulation. BNSF Railway’s operating procedures include practices to protect the environment from the risks inherent in railroad operations, which frequently involve transporting chemicals and other hazardous materials. Additionally, many of BNSF Railway’s land holdings are and have been used for industrial or transportation-related purposes or leased to commercial or industrial companies whose activities may have resulted in discharges onto the property. As a result, BNSF Railway is subject to environmental cleanup and enforcement actions. In particular, the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), also known as the Superfund law, as well as similar state laws, generally impose joint and several liability for cleanup and enforcement costs on current and former owners and operators of a site without regard to fault or the legality of the original conduct. BNSF Railway has been notified that it is a potentially responsible party (PRP) for study and cleanup costs at Superfund sites for which investigation and remediation payments are or will be made or are yet to be determined (the Superfund sites) and, in many instances, is one of several PRPs. In addition, BNSF Railway may be considered a PRP under certain other laws. Accordingly, under CERCLA and other federal and state statutes, BNSF Railway may be held jointly and severally liable for all environmental costs associated with a particular site. If there are other PRPs, BNSF Railway generally participates in the cleanup of these sites through cost-sharing agreements with terms that vary from site to site. Costs are typically allocated based on such factors as relative volumetric contribution of material, the amount of time the site was owned or operated and/or the portion of the total site owned or operated by each PRP.

BNSF Railway is involved in a number of administrative and judicial proceedings and other mandatory cleanup efforts for 225 sites, including 16 Superfund sites, at which it is participating in the study or cleanup, or both, of alleged environmental contamination.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) – (Continued)

Liabilities for environmental cleanup costs are recorded when BNSF Railway’s liability for environmental cleanup is probable and reasonably estimable. Subsequent adjustments to initial estimates are recorded as necessary based upon additional information developed in subsequent periods. Environmental costs include initial site surveys and environmental studies as well as costs for remediation of sites determined to be contaminated.

BNSF Railway estimates the ultimate cost of cleanup efforts at its known environmental sites on an annual basis during the third quarter. Ultimate cost estimates for environmental sites are based on current estimated percentage to closure ratios, possible remediation workplans and estimates of the costs and likelihood of each possible outcome, historical payment patterns, and benchmark patterns developed from data accumulated from industry and public sources, including the Environmental Protection Agency and other governmental agencies. These factors incorporate into the estimates experience gained from cleanup efforts at other similar sites.

Annual studies do not include: (i) contaminated sites of which the Company is not aware; (ii) additional amounts for third-party tort claims, which arise out of contaminants allegedly migrating from BNSF Railway property, due to a limited number of sites; or (iii) natural resource damage claims. BNSF Railway continues to estimate third-party tort claims on a site by site basis when the liability for such claims is probable and reasonably estimable. BNSF Railway’s recorded liability for third-party tort claims as of March 31, 2015 and December 31, 2014 was $13 million and $15 million, respectively.

On a quarterly basis, BNSF Railway monitors actual experience against the forecasted remediation and related payments made on existing sites and conducts ongoing environmental contingency analyses, which consider a combination of factors including independent consulting reports, site visits, legal reviews and analysis of the likelihood of other PRP's participation in, and their ability to pay for, cleanup. Adjustments to the Company’s estimates will continue to be recorded as necessary based on developments in subsequent periods. Additionally, environmental accruals, which are classified as materials and other in the Consolidated Statements of Income, include amounts for newly identified sites or contaminants, third-party claims and legal fees incurred for defense of third-party claims and recovery efforts.

The following tables summarize the activity in the Company’s accrued obligations for environmental matters (in millions):

	Three Months Ended March 31,
	2015			2014
Beginning balance	$	404		$	435
Accruals	1			2
Payments	(10		)	(10		)
Ending balance	$	395		$	427

At March 31, 2015, $60 million was included in current liabilities.

BNSF Railway’s environmental liabilities are not discounted. BNSF Railway anticipates that the majority of the accrued costs at March 31, 2015, will be paid over the next ten years, and no individual site is considered to be material.

BNSF RAILWAY COMPANY and SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) – (Continued)

Liabilities recorded for environmental costs represent BNSF Railway’s best estimate of its probable future obligation for the remediation and settlement of these sites and include both asserted and unasserted claims. Although recorded liabilities include BNSF Railway’s best estimate of all probable costs, without reduction for anticipated recoveries from third parties, BNSF Railway’s total cleanup costs at these sites cannot be predicted with certainty due to various factors such as the extent of corrective actions that may be required, evolving environmental laws and regulations, advances in environmental technology, the extent of other parties’ participation in cleanup efforts, developments in ongoing environmental analyses related to sites determined to be contaminated and developments in environmental surveys and studies of contaminated sites.

Because of the uncertainty surrounding these factors, it is reasonably possible that future costs for environmental liabilities may range from approximately $295 million to $530 million. However, BNSF Railway believes that the $395 million recorded at March 31, 2015, is the best estimate of the Company’s future obligation for environmental costs.

Although the final outcome of these environmental matters cannot be predicted with certainty, it is the opinion of BNSF Railway that none of these items, when finally resolved, will have a material adverse effect on the Company’s financial position or liquidity. However, the occurrence of a number of these items in the same period could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

Other Claims and Litigation

In addition to asbestos, other personal injury and environmental matters discussed above, BNSF Railway and its subsidiaries are also parties to a number of other legal actions and claims, governmental proceedings and private civil suits arising in the ordinary course of business, including those related to disputes and complaints involving certain transportation rates and charges. Some of the legal proceedings include claims for punitive as well as compensatory damages, and a few proceedings purport to be class actions. Although the final outcome of these matters cannot be predicted with certainty, considering among other things the meritorious legal defenses available and liabilities that have been recorded along with applicable insurance, BNSF Railway currently believes that none of these items, when finally resolved, will have a material adverse effect on the Company’s financial position or liquidity. However, an unexpected adverse resolution of one or more of these items could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

9. Related Party Transactions

BNSF Railway is involved with BNSF and certain of its subsidiaries in related party transactions in the ordinary course of business, which include payments made on each other’s behalf and performance of services. Under the terms of a tax allocation agreement with BNSF, BNSF Railway made federal and state income tax payments, net of refunds, of $79 million and $13 million during the three months ended March 31, 2015 and 2014, respectively, which are reflected in changes in working capital in the Consolidated Statement of Cash Flows.

At March 31, 2015 and December 31, 2014, BNSF Railway had $76 million and $44 million, respectively, of intercompany receivables which are reflected in accounts receivable in the respective Consolidated Balance Sheets. At March 31, 2015 and December 31, 2014, BNSF Railway had $54 million and $23 million of intercompany payables, respectively, which are reflected in accounts payable in the respective Consolidated Balance Sheets. Net intercompany balances are settled in the ordinary course of business.

At March 31, 2015 and December 31, 2014, BNSF Railway had $10,897 million and $9,963 million, respectively, of intercompany notes receivable from BNSF. The $934 millionincrease in intercompany notes receivable was due to loans to BNSF during the three months ended March 31, 2015. All intercompany notes have a variable interest rate of 1.0 percent above the monthly average of the daily effective Federal Funds rate. Interest is collected semi-annually on all intercompany notes receivable. Interest income from intercompany notes receivable is presented in interest income, related parties in the Consolidated Statements of Income.

BNSF Railway engages in various arm's-length transactions with affiliates in the ordinary course of business. The following tables summarize revenues earned by BNSF Railway for services provided to affiliates and expenditures to affiliates (in millions):

10. Comprehensive Income

Other comprehensive income refers to revenues, expenses, gains and losses that under generally accepted accounting principles are included in comprehensive income, a component of Stockholder’s Equity within the Consolidated Balance Sheets, rather than net income on the Consolidated Statements of Income. Under existing accounting standards, other comprehensive income may include, among other things, unrecognized gains and losses and prior service credit related to pension and other postretirement benefit plans.

11. Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606). The guidance in ASU 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification Topic 605, Revenue Recognition. ASU 2014-09 applies to most contracts with customers. Insurance and leasing contracts are excluded from the scope. ASU 2014-09 prescribes a five step framework in accounting for revenues from contracts within its scope, including (a) identification of the contract, (b) identification of the performance obligation under the contract, (c) determination of the transaction price, (d) allocation of the transaction price to the identified performance obligation and (e) recognition of revenue as the identified performance obligation is satisfied. ASU 2014-09 also prescribes additional disclosures and financial statement presentations. ASU 2014-09 is effective for public companies in annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. In April of 2015, the FASB tentatively decided to defer the effective date one year to annual reporting periods beginning after December, 15, 2017. Early adoption would be permitted, but not before the original effective date (annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period). ASU 2014-09 may be adopted retrospectively or under a modified retrospective method where the cumulative effect is recognized at the date of initial application. The Company has assessed the effects of this standard and does not expect it to have a material impact to the Consolidated Financial Statements.

In April 2015, the FASB issued Accounting Standards Update No. 2015-03 (ASU 2015-03), Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs. This standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. This standard is to be applied on a retrospective basis, wherein the balance sheet of each individual period presented is adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, an entity is required to comply with the applicable disclosures for a change in an accounting principle. These disclosures include the nature of and reason for the change in accounting principle, the transition method, a description of the prior-period information that has been retrospectively adjusted, and the effect of the change on the financial statement line items. This standard does not presently impact BNSF Railway and the Company does not expect this standard to have a material impact to the Company's financial condition or liquidity.

In April 2015, the FASB issued Accounting Standards Update No. 2015-05 (ASU 2015-05), Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. This standard provides guidance about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the software license element of the arrangement should be accounted for consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. ASU 2015-05 is effective for fiscal years beginning after December 15, 2015, and interim periods within those years. This standard can be adopted either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The Company is currently evaluating the effect this standard will have on its Consolidated Financial Statements.

Item 2. Management’s Narrative Analysis of Results of Operations.

Management’s narrative analysis relates to the results of operations of BNSF Railway Company and its majority-owned subsidiaries (collectively BNSF Railway, Registrant or Company). The following narrative analysis should be read in conjunction with the Consolidated Financial Statements and the accompanying notes.

The following narrative analysis of results of operations includes a comparative analysis of the three months ended March 31, 2015 and 2014.

Results of Operations

Revenues Summary

The following tables present BNSF Railway’s revenue information by business group:

	Revenues (in millions)				Cars / Units (in thousands)
	Three Months Ended March 31,				Three Months Ended March 31,
	2015		2014		2015	2014

Coal	2,115		2,174
Agricultural Products	4,303		4,136
Total Freight Revenues	$	2,179	$	2,155

Fuel Surcharges

Freight revenues include both revenue for transportation services and fuel surcharges. BNSF Railway’s fuel surcharge program is intended to recover its incremental fuel costs when fuel prices exceed a threshold fuel price. Fuel surcharges are calculated differently depending on the type of commodity transported. BNSF Railway has two standard fuel surcharge programs – Percent of Revenue and Mileage-Based. In addition, in certain commodities, fuel surcharge is calculated using a fuel price from a time period that can be up to 60 days earlier. In a period of volatile fuel prices or changing customer business mix, changes in fuel expense and fuel surcharge may significantly differ.

The following table presents fuel surcharge and fuel expense information (in millions):

	Three Months Ended March 31,
	2015		2014
Total fuel expense a	$	713	$	1,159
BNSF Railway fuel surcharges	$	483	$	703

^a  Total fuel expense includes locomotive and non-locomotive fuel.

Three Months EndedMarch 31, 2015 vs. the Three Months EndedMarch 31, 2014

Revenues

Revenues for the three months ended March 31, 2015, were $5,471 million, an increase of $137 million, or 3 percent as compared with the three months ended March 31, 2014. The increase in revenues is due to the following changes in revenues:

▪ Average revenue per car / unit increased by 1 percent as business mix changes as well as increased rate per car / unit were partially offset by lower fuel surcharges.

▪ Consumer Products unit volumes decreased primarily due to congestion on the U.S. West Coast caused by port labor disruptions.

▪ Industrial Products unit volumes increased primarily due to expanded shipments of frac sand and taconite, partially offset by less steel products.

▪ Coal unit volumes increased primarily due to higher demand.

▪ Agricultural Products unit volumes increased due to heightened customer corn and milo export demand and improved service.

Expenses

Operating expenses for the three months ended March 31, 2015, were $3,471 million, a decrease of $503 million, or 13 percent, as compared with the three months ended March 31, 2014. A significant portion of this decrease is due to the following changes in expenses, which includes increased costs in the prior year related to severe weather issues and service-related challenges:

▪ Compensation and benefits expense increased primarily due to higher average headcount and wage inflation.

▪ Fuel expense decreased due to lower average prices and improved efficiency, partially offset by higher volumes.

▪ Purchased services decreased primarily due to a favorable insurance recovery.

▪ There were no significant changes in depreciation and amortization expense, equipment rents expense, materials and other expense and the effective tax rate.

Forward-Looking Information

To the extent that statements made by the Company relate to the Company’s future economic performance or business outlook, projections or expectations of financial or operational results, or refer to matters that are not historical facts, such statements are “forward-looking” statements within the meaning of the federal securities laws.

Forward-looking statements involve a number of risks and uncertainties, and actual performance or results may differ materially. For a discussion of material risks and uncertainties that the Company faces, see the discussion in Item 1A, “Risk Factors,” of the Company’s Annual Report on Form 10-K. Important factors that could cause actual results to differ materially include, but are not limited to, the following:

•  Economic and industry conditions: material adverse changes in economic or industry conditions, both in the United States and globally; volatility in the capital or credit markets including changes affecting the timely availability and cost of capital; changes in customer demand, effects of adverse economic conditions affecting shippers or BNSF Railway’s supplier base, and effects due to more stringent regulatory policies such as the regulation of carbon dioxide emissions that could reduce the demand for coal or governmental tariffs or subsidies that could affect the demand for grain, the impact of low natural gas or oil prices on energy-related commodities demand, changes in environmental laws and other laws and regulations that could affect the demand for drilling products and products produced by drilling, changes in fuel prices and other key materials, the impact of high barriers to entry for prospective new suppliers and disruptions in supply chains for these materials; competition and consolidation within the transportation industry; and changes in crew availability, labor and benefits costs and labor difficulties, including stoppages affecting either BNSF Railway’s operations or customers’ abilities to deliver goods to BNSF Railway for shipment.

•   Legal, legislative and regulatory factors: developments and changes in laws and regulations, including those affecting train operations, the marketing of services or regulatory restrictions on equipment; the ultimate outcome of shipper and rate claims subject to adjudication; claims; investigations or litigation alleging violations of the antitrust laws; increased economic regulation of the rail industry through legislative action and revised rules and standards applied by the U.S. Surface Transportation Board in various areas including rates and services; developments in environmental investigations or proceedings with respect to rail operations or current or past ownership or control of real property or properties owned by others impacted by BNSF Railway operations; losses resulting from claims and litigation relating to personal injuries, asbestos and other occupational diseases; the release of hazardous materials, environmental contamination and damage to property; regulation, restrictions or caps, or other controls on transportation of petroleum-based fuel or other operating restrictions that could affect operations or increase costs; the availability of adequate insurance to cover the risks associated with operations and changes in tax rates and tax laws.

•   Operatingfactors: changes in operating conditions and costs; operational and other difficulties in implementing positive train control technology, including increased compliance or operational costs or penalties; restrictions on development and expansion plans due to environmental concerns; disruptions to BNSF Railway’s technology network including computer systems and software, such as cybersecurity intrusions, misappropriation of assets or sensitive information, corruption of data or operational disruptions; network congestion, including effects of greater than anticipated demand for transportation services and equipment; as well as natural events such as severe weather, fires, floods and earthquakes or man-made or other disruptions of BNSF Railway’s or other railroads’ operating systems, structures, or equipment including the effects of acts of terrorism on the Company’s system or other railroads’ systems or other links in the transportation chain.

The Company cautions against placing undue reliance on forward-looking statements, which reflect its current beliefs and are based on information currently available to it as of the date a forward-looking statement is made. The Company undertakes no obligation to revise forward-looking statements to reflect future events, changes in circumstances, or changes in beliefs. In the event the Company does update any forward-looking statement, no inference should be made that the Company will make additional updates with respect to that statement, related matters, or any other forward-looking statements.

Item 4. Controls and Procedures.

Based on their evaluation as of the end of the period covered by this quarterly report on Form 10-Q, BNSF Railway’s principal executive officer and principal financial officer have concluded that BNSF Railway’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934) are effective to ensure that information required to be disclosed by BNSF Railway in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in Securities and Exchange Commission rules and forms and that such information is accumulated and communicated to BNSF Railway’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Additionally, as of the end of the period covered by this report, BNSF Railway's principal executive officer and principal financial officer have concluded that there have been no changes in BNSF Railway's internal control over financial reporting that occurred during BNSF Railway’s first fiscal quarter that have materially affected, or are reasonably likely to materially affect, BNSF Railway's internal control over financial reporting.

PART II OTHER INFORMATION

Item 1. Legal Proceedings.

On March 19, 2015, the Washington Utilities and Transportation Commission (UTC) published a staff investigative report and a complaint against BNSF Railway alleging under-reporting of 14 hazardous materials releases during the time period between November 1, 2014 and February 24, 2015. The UTC claims that the alleged failures to report and associated releases resulted in 700 violations and $700,000 in fines.  The relevant regulations allow for penalties of $1,000 per violation and each day that a party fails to report a release may constitute a separate violation.  BNSF Railway has not formally responded to the charges as yet and, based on its internal review, it currently believes that over 90 percent of the alleged technical violations are incorrect, which, if accepted by the UTC, would result in an ultimate fine of less than $100,000.

The U.S. Department of Justice sent a notice to BNSF Railway on March 13, 2015 alleging violations of the Clean Water Act based on (i) four incidents that led to releases of fuel (and lube oil in one incident) from locomotives into water bodies within U.S. Environmental Protection Agency Region 8, and (ii) claimed deficiencies in four facility Spill Prevention Control and Countermeasure (SPCC) plans, and two Facility Response Plans (FRP). BNSF Railway disputes many elements of the notice, and its assessment indicates that only two of the four releases impacted water bodies. Although the final amount of any fine is unresolved, the fines could exceed $100,000.

On March 5, 2015, a loaded BNSF Railway crude oil train derailed near Galena, IL.   Some of the derailed railcars released crude oil in and around a wetland and a number of the derailed cars caught fire at the derailment location.  The Illinois Attorney General’s office and the Illinois Environmental Protection Agency informed BNSF Railway that they will be filing a complaint and an enforcement order against BNSF Railway with regard to the derailment and release of crude oil.    Although no complaint or order has been received and no penalty has yet been proposed, the total penalties could exceed $100,000.

Accounting Policies and Interim Results

Accounting Policies and Interim Results

The Consolidated Financial Statements should be read in conjunction with BNSF Railway Company’s Annual Report on Form 10-K for the year ended December 31, 2014, including the financial statements and notes thereto. The Consolidated Financial Statements include the accounts of BNSF Railway Company and its majority-owned subsidiaries, all of which are separate legal entities (collectively BNSF Railway or the Company). BNSF Railway is a wholly-owned subsidiary of Burlington Northern Santa Fe, LLC (BNSF), and is the principal operating subsidiary of BNSF. All intercompany accounts and transactions have been eliminated.

Subsequent to December 31, 2014, BNSF Railway added a significant accounting policy for investments. Investments in fixed maturity securities and equity securities are classified at the acquisition date and the classification is re-evaluated at each balance sheet date. Trading securities are investments acquired with the intent to sell in the near term and are carried at fair value. All investments currently held are classified as trading securities and net unrealized gains or losses are recorded in income.

On February 12, 2010, Berkshire Hathaway Inc., a Delaware corporation (Berkshire), acquired 100% of the outstanding shares of Burlington Northern Santa Fe Corporation common stock that it did not already own. The acquisition was completed through the merger (Merger) of a Berkshire wholly-owned merger subsidiary and Burlington Northern Santa Fe Corporation with the surviving entity renamed Burlington Northern Santa Fe, LLC. Earnings per share data has not been presented because BNSF has not issued stock or membership interests to the public.

The results of operations for any interim period are not necessarily indicative of the results of operations to be expected for the entire year. In the opinion of management, the unaudited financial statements reflect all adjustments (consisting of only normal recurring adjustments, except as disclosed) necessary for a fair statement of BNSF Railway’s consolidated financial position as of March 31, 2015, and the results of operations for the three months ended March 31, 2015 and 2014.

Accumulated Other Comprehensive Income (Loss), Net of Tax [Abstract]

Comprehensive Income

Comprehensive Income

Other comprehensive income refers to revenues, expenses, gains and losses that under generally accepted accounting principles are included in comprehensive income, a component of Stockholder’s Equity within the Consolidated Balance Sheets, rather than net income on the Consolidated Statements of Income. Under existing accounting standards, other comprehensive income may include, among other things, unrecognized gains and losses and prior service credit related to pension and other postretirement benefit plans.    

The following tables provide the components of accumulated other comprehensive income / (loss) (AOCI) by component (in millions):

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

Accounting Pronouncements

Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2014-09 (ASU 2014-09), Revenue from Contracts with Customers (Topic 606). The guidance in ASU 2014-09 supersedes the revenue recognition requirements in Accounting Standards Codification Topic 605, Revenue Recognition. ASU 2014-09 applies to most contracts with customers. Insurance and leasing contracts are excluded from the scope. ASU 2014-09 prescribes a five step framework in accounting for revenues from contracts within its scope, including (a) identification of the contract, (b) identification of the performance obligation under the contract, (c) determination of the transaction price, (d) allocation of the transaction price to the identified performance obligation and (e) recognition of revenue as the identified performance obligation is satisfied. ASU 2014-09 also prescribes additional disclosures and financial statement presentations. ASU 2014-09 is effective for public companies in annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. In April of 2015, the FASB tentatively decided to defer the effective date one year to annual reporting periods beginning after December, 15, 2017. Early adoption would be permitted, but not before the original effective date (annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period). ASU 2014-09 may be adopted retrospectively or under a modified retrospective method where the cumulative effect is recognized at the date of initial application. The Company has assessed the effects of this standard and does not expect it to have a material impact to the Consolidated Financial Statements.

In April 2015, the FASB issued Accounting Standards Update No. 2015-03 (ASU 2015-03), Interest - Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs. This standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted for financial statements that have not been previously issued. This standard is to be applied on a retrospective basis, wherein the balance sheet of each individual period presented is adjusted to reflect the period-specific effects of applying the new guidance. Upon transition, an entity is required to comply with the applicable disclosures for a change in an accounting principle. These disclosures include the nature of and reason for the change in accounting principle, the transition method, a description of the prior-period information that has been retrospectively adjusted, and the effect of the change on the financial statement line items. This standard does not presently impact BNSF Railway and the Company does not expect this standard to have a material impact to the Company's financial condition or liquidity.

In April 2015, the FASB issued Accounting Standards Update No. 2015-05 (ASU 2015-05), Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. This standard provides guidance about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the software license element of the arrangement should be accounted for consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. ASU 2015-05 is effective for fiscal years beginning after December 15, 2015, and interim periods within those years. This standard can be adopted either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The Company is currently evaluating the effect this standard will have on its Consolidated Financial Statements.

Other Assets

Other Assets

In July 2010, the Company entered into a low-income housing partnership (the Partnership) as the limited partner, holding a 99.9% interest in the Partnership. The Partnership is a variable interest entity (VIE), with the purpose of developing and operating low-income housing rental properties. Recovery of the Company’s investment is accomplished through the utilization of low-income housing tax credits and the tax benefits of Partnership losses. The general partner, who holds a 0.1% interest in the Partnership, is an unrelated third party and is responsible for controlling and managing the business and financial operation of the Partnership. As the Company does not have the power to direct the activities that most significantly impact the Partnership’s economic performance, the Company is not the primary beneficiary and therefore, does not consolidate the Partnership. As of March 31, 2015 and December 31, 2014, the assets of the unconsolidated Partnership totaled approximately $320 million and $330 million, respectively. The Company does not provide financial support to the Partnership that it was not previously contractually obligated to provide.

The Company has accounted for its investment in the Partnership using the effective yield method. The risk of loss of the Company's investment in the Partnership is considered low as an affiliate of the general partner has provided certain guarantees of tax credits and minimum annual returns. For the three months ended March 31, 2015 and 2014, the Company recognized a reduction to income tax expense of $9 million and $10 million, respectively. The Company’s maximum exposure to loss related to the Partnership is the unamortized investment balance. The following table provides information related to this Partnership (in millions):

	March 31, 2015		December 31, 2014
Unamortized investment balance classified as Other Assets	$	298	$	314
Remaining commitment classified as Other Liabilities	$	18	$	18
Maximum exposure to loss	$	298	$	314

The remaining commitment of $18 million is expected to be paid in 2015.

Debt

Debt

Fair Value of Debt Instruments

At March 31, 2015, and December 31, 2014, the fair value of BNSF Railway's debt, excluding capital leases, was $735 million and $738 million, respectively, while the book value, which also excludes capital leases and the associated unamortized fair value adjustment under acquisition method accounting related to capital leases, was $635 million and $651 million, respectively. The fair value of BNSF Railway's debt is primarily based on market value price models using observable market-based data for the same or similar issues, or on the estimated rates that would be offered to BNSF Railway for debt of the same remaining maturities (Level 2 inputs).

Guarantees

As of March 31, 2015, BNSF Railway has not been called upon to perform under the guarantees specifically disclosed in this footnote and does not anticipate a significant performance risk in the foreseeable future.

Debt and other obligations of non-consolidated entities guaranteed by the Company as of March 31, 2015, were as follows (dollars in millions):

	Guarantees
	BNSF Railway Ownership Percentage		Principal Amount Guaranteed		Maximum Future Payments		Maximum Recourse Amounta		Remaining Term (in years)	Capitalized Obligations
Kinder Morgan Energy Partners, L.P.	0.5	%	$	190	$	190	$	—	Termination of Ownership	$	2	b
Chevron Phillips Chemical Company LP	—	%	N/Ad		N/Ad		N/Ad		2	$	4	c

^a  Reflects the maximum amount the Company could recover from a third party other than the counterparty.

^b  Reflects capitalized obligations that are recorded on the Company’s Consolidated Balance Sheet.

^c  Reflects the asset and corresponding liability for the fair value of these guarantees required by authoritative accounting guidance related to guarantees.

^d  There is no cap to the liability that can be sought from BNSF Railway for BNSF Railway’s negligence or the negligence of the indemnified party. However, BNSF Railway could receive reimbursement from certain insurance policies if the liability exceeds a certain amount.

Kinder Morgan Energy Partners, L.P.

Santa Fe Pacific Pipelines, Inc., an indirect, wholly-owned subsidiary of BNSF Railway, has a guarantee in connection with its remaining special limited partnership interest in Santa Fe Pacific Pipeline Partners, L.P. (SFPP), a subsidiary of Kinder Morgan Energy Partners, L.P., to be paid only upon default by the partnership. All obligations with respect to the guarantee will cease upon termination of ownership rights, which would occur upon a put notice issued by BNSF Railway or the exercise of the call rights by the general partners of SFPP.

Chevron Phillips Chemical Company LP

In 2007, BNSF Railway entered into an indemnity agreement with Chevron Phillips Chemical Company LP (Chevron Phillips), granting certain rights of indemnity from BNSF Railway, in order to facilitate access to a new storage facility. Under certain circumstances, payment under this obligation may be required in the event Chevron Phillips were to incur certain liabilities or other incremental costs resulting from trackage access.

Indemnities

In the ordinary course of business, BNSF Railway enters into agreements with third parties that include indemnification clauses. The Company believes that these clauses are generally customary for the types of agreements in which they are included. At times, these clauses may involve indemnification for the acts of the Company, its employees and agents, indemnification for another party’s acts, indemnification for future events, indemnification based upon a certain standard of performance, indemnification for liabilities arising out of the Company’s use of leased equipment or other property, or other types of indemnification. Despite the uncertainty whether events which would trigger the indemnification obligations would ever occur, the Company does not believe that these indemnity agreements will have a material adverse effect on the Company’s results of operations, financial position or liquidity. Additionally, the Company believes that, due to lack of historical payment experience, the fair value of indemnities cannot be estimated with any amount of certainty. However, the fair value of any such amount would be immaterial to the Consolidated Financial Statements. Agreements that reflect unique circumstances, particularly agreements that contain guarantees that indemnify for another party’s acts, are disclosed separately, if appropriate. Unless separately disclosed above, no fair value liability related to indemnities has been recorded in the Consolidated Financial Statements.

Variable Interest Entities - Leases

BNSF Railway has entered into various equipment lease transactions in which the structure of the lease contains VIEs. These VIEs were created solely for the lease transactions and have no other activities, assets or liabilities outside of the lease transactions. In some of the arrangements, BNSF Railway has the option to purchase some or all of the equipment at a fixed-price, thereby creating variable interests for BNSF Railway in the VIEs. The future minimum lease payments associated with the VIE leases were approximately $3 billion as of March 31, 2015.

In the event the leased equipment is destroyed, BNSF Railway is obligated to either replace the equipment or pay a fixed loss amount. The inclusion of the fixed loss amount is a standard clause within equipment lease arrangements. Historically, BNSF Railway has not incurred significant losses related to this clause. As such, it is not anticipated that the maximum exposure to loss would materially differ from the future minimum lease payments.

BNSF Railway does not provide financial support to the VIEs that it was not previously contractually obligated to provide.

BNSF Railway maintains and operates the equipment based on contractual obligations within the lease arrangements, which set specific guidelines consistent within the industry. As such, BNSF Railway has no control over activities that could materially impact the fair value of the leased equipment. BNSF Railway does not hold the power to direct the activities of the VIEs and therefore does not control the ongoing activities that have a significant impact on the economic performance of the VIEs. Additionally, BNSF Railway does not have the obligation to absorb losses of the VIEs or the right to receive benefits of the VIEs that could potentially be significant to the VIEs. Depending on market conditions, the fixed-price purchase options could potentially provide benefit to the Company; however, any benefits potentially received from a fixed-price purchase option are expected to be minimal. Based on these factors, BNSF Railway is not the primary beneficiary of the VIEs. As BNSF Railway is not the primary beneficiary and the VIE leases are classified as operating leases, there are no assets or liabilities related to the VIEs recorded in the Company's Consolidated Balance Sheet.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Commitments and Contingencies

Personal Injury

Personal injury claims, including asbestos claims and employee work-related injuries and third-party injuries (collectively, other personal injury), are a significant expense for the railroad industry. Personal injury claims by BNSF Railway employees are subject to the provisions of the Federal Employers’ Liability Act (FELA) rather than state workers’ compensation laws. FELA’s system of requiring the finding of fault, coupled with unscheduled awards and reliance on the jury system, contributed to increased expenses in past years. Other proceedings include claims by non-employees for punitive as well as compensatory damages. A few proceedings purport to be class actions. The variability present in settling these claims, including non-employee personal injury and matters in which punitive damages are alleged, could result in increased expenses in future years. BNSF Railway has implemented a number of safety programs designed to reduce the number of personal injuries as well as the associated claims and personal injury expense.

BNSF Railway records an undiscounted liability for personal injury claims when the expected loss is both probable and reasonably estimable. The liability and ultimate expense projections are estimated using standard actuarial methodologies. Liabilities recorded for unasserted personal injury claims are based on information currently available. Due to the inherent uncertainty involved in projecting future events such as the number of claims filed each year, developments in judicial and legislative standards and the average costs to settle projected claims, actual costs may differ from amounts recorded. BNSF Railway has obtained insurance coverage for certain claims, as discussed under the heading “BNSF Insurance Company.” Expense accruals and any required adjustments are classified as materials and other in the Consolidated Statements of Income.

Asbestos

The Company is party to a number of personal injury claims by employees and non-employees who may have been exposed to asbestos. The heaviest exposure for certain BNSF Railway employees was due to work conducted in and around the use of steam locomotive engines that were phased out between the years of 1950 and 1967. However, other types of exposures, including exposure from locomotive component parts and building materials, continued after 1967 until they were substantially eliminated at BNSF Railway by 1985.

BNSF Railway assesses its unasserted asbestos liability exposure on an annual basis during the third quarter. BNSF Railway determines its asbestos liability by estimating its exposed population, the number of claims likely to be filed, the number of claims that will likely require payment and the estimated cost per claim. Estimated filing and dismissal rates and average cost per claim are determined utilizing recent claim data and trends.

Throughout the year, BNSF Railway monitors actual experience against the number of forecasted claims and expected claim payments and will record adjustments to the Company’s estimates as necessary.

Based on BNSF Railway’s estimate of the potentially exposed employees and related mortality assumptions, it is anticipated that unasserted asbestos claims will continue to be filed through the year 2050. The Company recorded an amount for the full estimated filing period through 2050 because it had a relatively finite exposed population (former and current employees hired prior to 1985), which it was able to identify and reasonably estimate and about which it had obtained reliable demographic data (including age, hire date and occupation) derived from industry or BNSF Railway specific data that was the basis for the study. BNSF Railway projects that approximately 60, 80 and 95 percent of the future unasserted asbestos claims will be filed within the next 10, 15 and 25 years, respectively.

Other Personal Injury

BNSF Railway estimates its other personal injury liability claims and expense quarterly based on the covered population, activity levels and trends in frequency and the costs of covered injuries. Estimates include unasserted claims except for certain repetitive stress and other occupational trauma claims that allegedly result from prolonged repeated events or exposure. Such claims are estimated on an as-reported basis because the Company cannot estimate the range of reasonably possible loss due to other non-work related contributing causes of such injuries and the fact that continued exposure is required for the potential injury to manifest itself as a claim. BNSF Railway has not experienced any significant adverse trends related to these types of claims in recent years.

BNSF Railway monitors quarterly actual experience against the number of forecasted claims to be received, the forecasted number of claims closing with payment and expected claim payments. Adjustments to the Company’s estimates are recorded quarterly as necessary or more frequently as new events or revised estimates develop.

The following tables summarize the activity in the Company’s accrued obligations for asbestos and other personal injury matters (in millions):

	Three Months Ended March 31,
	2015			2014
Beginning balance	$	375		$	387
Accruals	18			18
Payments	(20		)	(19		)
Ending balance	$	373		$	386

At March 31, 2015, $80 million was included in current liabilities. Defense and processing costs, which are recorded on an as-reported basis, were not included in the recorded liability. The Company is primarily self-insured for personal injury claims.

Because of the uncertainty surrounding the ultimate outcome of personal injury claims, it is reasonably possible that future costs to settle personal injury claims may range from approximately $330 million to $440 million. However, BNSF Railway believes that the $373 million recorded at March 31, 2015 is the best estimate of the Company’s future obligation for the settlement of personal injury claims.

The amounts recorded by BNSF Railway for personal injury liabilities were based upon currently known facts. Future events, such as the number of new claims to be filed each year, the average cost of disposing of claims, as well as the numerous uncertainties surrounding personal injury litigation in the United States, could cause the actual costs to be higher or lower than projected.

Although the final outcome of personal injury matters cannot be predicted with certainty, considering among other things the meritorious legal defenses available and liabilities that have been recorded, it is the opinion of BNSF Railway that none of these items, when finally resolved, will have a material adverse effect on the Company’s financial position or liquidity. However, the occurrence of a number of these items in the same period could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

BNSF Insurance Company

Burlington Northern Santa Fe Insurance Company, Ltd. (BNSF IC), a wholly-owned subsidiary of BNSF, provides insurance coverage for certain risks, FELA claims, railroad protective and force account insurance claims and certain excess general liability and property coverage, and certain other claims which are subject to reinsurance. During the three months ended March 31, 2015 and 2014, BNSF IC wrote insurance coverage with premiums totaling $51 million and $45 million, respectively, for BNSF Railway, net of reimbursements from third parties. During this same time, BNSF Railway recognized $20 million and $21 million, respectively, in expense related to those premiums, which is classified as purchased services in the Consolidated Statements of Income. At March 31, 2015, unamortized premiums remaining on the Consolidated Balance Sheet were $38 million. During the three months ended March 31, 2015 and 2014, BNSF IC made claim payments totaling $180 million and $41 million, respectively, for settlement of covered claims. At March 31, 2015 and December 31, 2014, claims receivables from BNSF IC were $5 million and $10 million, respectively.

Environmental

The Company’s operations, as well as those of its competitors, are subject to extensive federal, state and local environmental regulation. BNSF Railway’s operating procedures include practices to protect the environment from the risks inherent in railroad operations, which frequently involve transporting chemicals and other hazardous materials. Additionally, many of BNSF Railway’s land holdings are and have been used for industrial or transportation-related purposes or leased to commercial or industrial companies whose activities may have resulted in discharges onto the property. As a result, BNSF Railway is subject to environmental cleanup and enforcement actions. In particular, the federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA), also known as the Superfund law, as well as similar state laws, generally impose joint and several liability for cleanup and enforcement costs on current and former owners and operators of a site without regard to fault or the legality of the original conduct. BNSF Railway has been notified that it is a potentially responsible party (PRP) for study and cleanup costs at Superfund sites for which investigation and remediation payments are or will be made or are yet to be determined (the Superfund sites) and, in many instances, is one of several PRPs. In addition, BNSF Railway may be considered a PRP under certain other laws. Accordingly, under CERCLA and other federal and state statutes, BNSF Railway may be held jointly and severally liable for all environmental costs associated with a particular site. If there are other PRPs, BNSF Railway generally participates in the cleanup of these sites through cost-sharing agreements with terms that vary from site to site. Costs are typically allocated based on such factors as relative volumetric contribution of material, the amount of time the site was owned or operated and/or the portion of the total site owned or operated by each PRP.

BNSF Railway is involved in a number of administrative and judicial proceedings and other mandatory cleanup efforts for 225 sites, including 16 Superfund sites, at which it is participating in the study or cleanup, or both, of alleged environmental contamination.

Liabilities for environmental cleanup costs are recorded when BNSF Railway’s liability for environmental cleanup is probable and reasonably estimable. Subsequent adjustments to initial estimates are recorded as necessary based upon additional information developed in subsequent periods. Environmental costs include initial site surveys and environmental studies as well as costs for remediation of sites determined to be contaminated.

BNSF Railway estimates the ultimate cost of cleanup efforts at its known environmental sites on an annual basis during the third quarter. Ultimate cost estimates for environmental sites are based on current estimated percentage to closure ratios, possible remediation workplans and estimates of the costs and likelihood of each possible outcome, historical payment patterns, and benchmark patterns developed from data accumulated from industry and public sources, including the Environmental Protection Agency and other governmental agencies. These factors incorporate into the estimates experience gained from cleanup efforts at other similar sites.

Annual studies do not include: (i) contaminated sites of which the Company is not aware; (ii) additional amounts for third-party tort claims, which arise out of contaminants allegedly migrating from BNSF Railway property, due to a limited number of sites; or (iii) natural resource damage claims. BNSF Railway continues to estimate third-party tort claims on a site by site basis when the liability for such claims is probable and reasonably estimable. BNSF Railway’s recorded liability for third-party tort claims as of March 31, 2015 and December 31, 2014 was $13 million and $15 million, respectively.

On a quarterly basis, BNSF Railway monitors actual experience against the forecasted remediation and related payments made on existing sites and conducts ongoing environmental contingency analyses, which consider a combination of factors including independent consulting reports, site visits, legal reviews and analysis of the likelihood of other PRP's participation in, and their ability to pay for, cleanup. Adjustments to the Company’s estimates will continue to be recorded as necessary based on developments in subsequent periods. Additionally, environmental accruals, which are classified as materials and other in the Consolidated Statements of Income, include amounts for newly identified sites or contaminants, third-party claims and legal fees incurred for defense of third-party claims and recovery efforts.

The following tables summarize the activity in the Company’s accrued obligations for environmental matters (in millions):

	Three Months Ended March 31,
	2015			2014
Beginning balance	$	404		$	435
Accruals	1			2
Payments	(10		)	(10		)
Ending balance	$	395		$	427

At March 31, 2015, $60 million was included in current liabilities.

BNSF Railway’s environmental liabilities are not discounted. BNSF Railway anticipates that the majority of the accrued costs at March 31, 2015, will be paid over the next ten years, and no individual site is considered to be material.

Liabilities recorded for environmental costs represent BNSF Railway’s best estimate of its probable future obligation for the remediation and settlement of these sites and include both asserted and unasserted claims. Although recorded liabilities include BNSF Railway’s best estimate of all probable costs, without reduction for anticipated recoveries from third parties, BNSF Railway’s total cleanup costs at these sites cannot be predicted with certainty due to various factors such as the extent of corrective actions that may be required, evolving environmental laws and regulations, advances in environmental technology, the extent of other parties’ participation in cleanup efforts, developments in ongoing environmental analyses related to sites determined to be contaminated and developments in environmental surveys and studies of contaminated sites.

Because of the uncertainty surrounding these factors, it is reasonably possible that future costs for environmental liabilities may range from approximately $295 million to $530 million. However, BNSF Railway believes that the $395 million recorded at March 31, 2015, is the best estimate of the Company’s future obligation for environmental costs.

Although the final outcome of these environmental matters cannot be predicted with certainty, it is the opinion of BNSF Railway that none of these items, when finally resolved, will have a material adverse effect on the Company’s financial position or liquidity. However, the occurrence of a number of these items in the same period could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

Other Claims and Litigation

In addition to asbestos, other personal injury and environmental matters discussed above, BNSF Railway and its subsidiaries are also parties to a number of other legal actions and claims, governmental proceedings and private civil suits arising in the ordinary course of business, including those related to disputes and complaints involving certain transportation rates and charges. Some of the legal proceedings include claims for punitive as well as compensatory damages, and a few proceedings purport to be class actions. Although the final outcome of these matters cannot be predicted with certainty, considering among other things the meritorious legal defenses available and liabilities that have been recorded along with applicable insurance, BNSF Railway currently believes that none of these items, when finally resolved, will have a material adverse effect on the Company’s financial position or liquidity. However, an unexpected adverse resolution of one or more of these items could have a material adverse effect on the results of operations in a particular quarter or fiscal year.

Related Party Transactions

BNSF Railway is involved with BNSF and certain of its subsidiaries in related party transactions in the ordinary course of business, which include payments made on each other’s behalf and performance of services. Under the terms of a tax allocation agreement with BNSF, BNSF Railway made federal and state income tax payments, net of refunds, of $79 million and $13 million during the three months ended March 31, 2015 and 2014, respectively, which are reflected in changes in working capital in the Consolidated Statement of Cash Flows.

At March 31, 2015 and December 31, 2014, BNSF Railway had $76 million and $44 million, respectively, of intercompany receivables which are reflected in accounts receivable in the respective Consolidated Balance Sheets. At March 31, 2015 and December 31, 2014, BNSF Railway had $54 million and $23 million of intercompany payables, respectively, which are reflected in accounts payable in the respective Consolidated Balance Sheets. Net intercompany balances are settled in the ordinary course of business.
