Management's Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial

reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial

statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal

control over financial reporting may not prevent or detect misstatements.

Management has assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2019 using the

criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013).

Based on this assessment, management has determined that the Company's internal control over financial reporting was effective as of

December 31, 2019.

KPMG LLP, an independent registered public accounting firm, has issued an unqualified audit report on the effectiveness of the Company's

internal control over financial reporting as of December 31, 2019 and has also expressed an unqualified audit opinion on the Company's 2019

consolidated financial statements as stated in their Reports of Independent Registered Public Accounting Firm dated January 31, 2020.

Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors
Canadian National Railway Company:
Opinion on the consolidated financial statements
We have audited the accompanying consolidated balance sheets of Canadian National Railway Company (the "Company") as of December 31,
2019 and 2018, the related consolidated statements of income, comprehensive income, changes in shareholders' equity and cash flows for
each of the years in the three‐year period ended December 31, 2019, and the related notes (collectively, the "consolidated financial
statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company
as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years in the three‐year period ended
December 31, 2019, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the
Company's internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control – Integrated
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated January 31, 2020
expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.
Change in accounting principle
As discussed in Note 2 to the consolidated financial statements, the Company has changed its method of accounting for leases as of
January 1, 2019 due to the adoption of Accounting Standards Codification Topic 842 Leases, using a modified retrospective adoption
approach.
Basis for opinion
These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on
these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or
fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements,
whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis,
evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting
principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial
statements. We believe that our audits provide a reasonable basis for our opinion.
Critical audit matters
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that
were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to
the consolidated financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of
critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by
communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to
which they relate.
Evaluation of income taxes
As discussed in Note 6 to the consolidated financial statements, the net deferred income tax liability was $7,844 million as of December 31,
2019 and income tax expense was $1,213 million for the year ended December 31, 2019. The Company operates in different tax jurisdictions
which requires the Company to make significant judgments and estimates in relation to its tax positions.
We identified the evaluation of the net deferred income tax liability and income tax expense as a critical audit matter due to the magnitude
of these tax balances and complexities in the evaluation of the application of the relevant tax regulations applicable to the Company. A higher
degree of auditor judgment is required in assessing certain of the Company’s tax positions and balances.
	CN \| 2019 Annual Report	55


Report of Independent Registered Public Accounting Firm
The primary procedures we performed to address this critical audit matter included the following. We tested certain internal controls over
the Company’s income tax accounting process, including controls related to the Company’s reconciliation and analysis of its deferred income
tax balances. We involved income tax and transfer pricing professionals with specialized skills and knowledge to assist in: (1) assessing the
Company’s interpretation of the relevant tax regulations, including the impact of the U.S. Tax Cuts and Jobs Act; (2) evaluating the Company’s
tax positions and transfer pricing arrangements; (3) analyzing the Company’s deferred income tax balances by comparing prior year tax
estimates to actual tax returns filed, and evaluating the Company’s reconciliation of the deferred income tax balances to the underlying
temporary differences.
Evaluation of capitalization of costs relating to track and railway infrastructure and depreciation related to properties
As discussed in Notes 1 and 9 to the consolidated financial statements, capital additions were $3,865 million for the year ended December 31,
2019, of which $1,489 million related to track and railway infrastructure maintenance, including the replacement of rail, ties, bridge
improvements, and other general track maintenance. For self-constructed properties, expenditures include direct material, labor, and contracted
services, as well as other allocated costs. The Company follows the group method of depreciation whereby a single composite depreciation
rate is applied to the gross investment in a class of similar assets. These Notes also discussed that depreciation expense relating to properties
was $1,559 million for the year ended December 31, 2019. The Company performs comprehensive Canadian and U.S. depreciation studies on
specific asset groups on a periodic basis, which require significant judgment. These studies incorporate numerous assumptions related to the
remaining service lives and the U.S. studies involve a third party expert. The depreciation studies consider, among other factors, the analysis of
historical retirement data using recognized life analysis techniques, and the forecasting of asset life characteristics.
We identified the evaluation of capitalization of costs relating to track and railway infrastructure and depreciation expense related to
properties as a critical audit matter. The magnitude and complexities in self-constructed properties, as well as the judgments involved in the
determination of the expenditure meeting the Company’s pre-determined capitalization criteria requires subjective auditor judgment. Further,
there is a higher degree of auditor judgment required in evaluating the estimated service lives of the respective asset classes. Changes in
estimated service lives can significantly impact the amount of depreciation expense.
The primary procedures we performed to address this critical audit matter included the following. We tested certain internal controls over
the Company’s capital additions process, including controls related to the monitoring of budget versus actual costs on capital projects and the
Company’s analysis of projects assessing that the expenditures charged to projects meet the Company’s pre-determined capitalization criteria.
We also tested certain internal controls over the Company’s depreciation expense process, including controls related to the Company’s
assessment of the Canadian and U.S. depreciation studies. We traced a sample of capital expenditure additions to underlying documentation
and assessed whether the expenditure met the Company’s pre-determined capitalization criteria. The testing was performed at a disaggregated
level by type of cost (including direct material, labor, and contracted services), and included comparisons to prior period per unit measures by
region. We evaluated the key assumptions in determining the estimated service lives in the Company’s Canadian and U.S. depreciation studies
by testing the historical data used in the depreciation studies through comparison to underlying documentation. In addition, we compared the
Company’s historical retirement patterns to the service lives used in the depreciation studies, and interviewed the Company’s personnel with
specialized knowledge of the subject matter and a third party expert.

Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors
Canadian National Railway Company:
Opinion on internal control over financial reporting
We have audited the Canadian National Railway Company's (the "Company") internal control over financial reporting as of December 31, 2019,
based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the
Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of
December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the
consolidated balance sheets of the Company as of December 31, 2019 and 2018, the related consolidated statements of income,
comprehensive income, changes in shareholders' equity and cash flows for each of the years in the three-year period ended December 31, 2019,
and the related notes (collectively, the "consolidated financial statements"), and our report dated January 31, 2020 expressed an unqualified
opinion on those consolidated financial statements.
Basis for opinion
The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial
Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a
public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S.
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit
of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed
risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit
provides a reasonable basis for our opinion.
Definition and limitations of internal control over financial reporting
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A
company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance
that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and
directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company's assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions,
or that the degree of compliance with the policies or procedures may deteriorate.

Notes to the Consolidated Financial Statements
Canadian National Railway Company, together with its wholly-owned subsidiaries, collectively "CN" or the "Company," is engaged in the rail and
related transportation business. CN spans Canada and mid-America, from the Atlantic and Pacific oceans to the Gulf of Mexico, serving the
cities and ports of Vancouver, Prince Rupert (British Columbia), Montreal, Halifax, New Orleans and Mobile (Alabama), and the metropolitan
areas of Toronto, Edmonton, Winnipeg, Calgary, Chicago, Memphis, Detroit, Duluth (Minnesota)/Superior (Wisconsin) and Jackson (Mississippi),
with connections to all points in North America. CN's freight revenues are derived from the movement of a diversified and balanced portfolio of
goods, including petroleum and chemicals, grain and fertilizers, coal, metals and minerals, forest products, intermodal and automotive.
1 – Summary of significant accounting policies
Basis of presentation
These consolidated financial statements are expressed in Canadian dollars, except where otherwise indicated, and have been prepared in accordance with United States generally accepted accounting principles (GAAP) as codified in the Financial Accounting Standards Board
(FASB) Accounting Standards Codification (ASC).
Principles of consolidation
These consolidated financial statements include the accounts of all subsidiaries and variable interest entities for which the Company is the
primary beneficiary. The Company is the primary beneficiary of the Employee Benefit Plan Trusts ("Share Trusts") as the Company funds the
Share Trusts. The Company's investments in which it has significant influence are accounted for using the equity method and all other
investments for which fair value is not readily determinable are accounted for at cost minus impairment, plus or minus observable price
changes.
Use of estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the
reported amounts of revenues, expenses, assets and liabilities, and the disclosure of contingent assets and liabilities at the date of the financial
statements. On an ongoing basis, management reviews its estimates, including those related to goodwill, intangible assets, identified assets
and liabilities acquired in business combinations, income taxes, depreciation, pensions and other postretirement benefits, personal injury and
other claims, and environmental matters, based upon available information. Actual results could differ from these estimates.
Revenues
Nature of services
The Company's revenues consist of freight revenues and other revenues. Freight revenues include revenue from the movement of freight over
rail and are derived from the following seven commodity groups:
•	Petroleum and chemicals, which includes chemicals and plastics, refined petroleum products, crude and condensate, and sulfur;
•	Metals and minerals, which includes energy materials, metals, minerals, and iron ore;
•	Forest products, which includes lumber, pulp, paper, and panels;
•	Coal, which includes coal and petroleum coke;
•	Grain and fertilizers, which includes Canadian regulated grain, Canadian commercial grain, U.S. grain, potash and other fertilizers;
•	Intermodal, which includes rail and trucking services for domestic and international traffic; and
•	Automotive, which includes finished vehicles and auto parts.
Freight revenues also comprise revenues for optional services beyond the basic movement of freight including asset use, switching, storage,
and other services.
Other revenues are derived from non-rail logistics services that support the Company's rail business including vessels and docks,
transloading and distribution, automotive logistics, and freight forwarding and transportation management.
Revenue recognition
Revenues are recognized when control of promised services is transferred to customers in an amount that reflects the consideration the
Company expects to be entitled to receive in exchange for those services.
The Company accounts for contracts with customers when it has approval and commitment from both parties, each party's rights have
been identified, payment terms are defined, the contract has commercial substance and collection is probable. For contracts that involve
multiple performance obligations, the Company allocates the transaction price to each performance obligation in the contract based on relative
standalone selling prices and recognizes revenue when, or as, performance obligations in the contract are satisfied.
Revenues are presented net of taxes collected from customers and remitted to governmental authorities.

Notes to the Consolidated Financial Statements

Freight revenues

Freight services are arranged through publicly-available tariffs or customer-specific agreements that establish the pricing, terms and conditions

for freight services offered by the Company. For revenue recognition purposes, a contract for the movement of freight over rail exists when

shipping instructions are sent by a customer and have been accepted by the Company in connection with the relevant tariff or customer-

specific agreement.

Revenues for the movement of freight over rail are recognized over time due to the continuous transfer of control to the customer as

freight moves from origin to destination. Progress towards completion of the performance obligation is measured based on the transit time of

freight from origin to destination. The allocation of revenues between periods is based on the relative transit time in each period with expenses

recorded as incurred. Revenues related to freight contracts that require the involvement of another rail carrier to move freight from origin to

destination are reported on a net basis. Freight movements are completed over a short period of time and are generally completed before

payment is due. Freight receivables are included in Accounts receivable on the Consolidated Balance Sheets.

The Company has no material contract assets associated with freight revenues.

Contract liabilities represent consideration received from customers for which the related performance obligation has not been satisfied.

Contract liabilities are recognized into revenues when or as the related performance obligation is satisfied. The Company includes contract

liabilities within Accounts payable and other and Other liabilities and deferred credits on the Consolidated Balance Sheets.

Revenues for optional services are recognized at a point in time or over time as performance obligations are satisfied, depending on the

nature of the service.

Freight contracts may be subject to variable consideration in the form of volume-based incentives, rebates, or other items, which affect the

transaction price. Variable consideration is recognized as revenue to the extent that it is probable that a significant reversal in the amount of

cumulative revenue recognized will not occur. Variable consideration is accrued on the basis of management's best estimate of the expected

amount, which is based on available historical, current and forecasted information.

Other revenues

Other revenues are recognized at a point in time or over time as performance obligations are satisfied, depending on the nature of the service.

Income taxes

The Company follows the asset and liability method of accounting for income taxes. Under the asset and liability method, the change in the net

deferred income tax asset or liability is included in the computation of Net income or Other comprehensive income (loss). Deferred income tax

assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which temporary differences are

expected to be recovered or settled.

Earnings per share

Basic earnings per share is calculated using the weighted-average number of basic shares outstanding during the period. The weighted-average

number of basic shares outstanding excludes shares held in the Share Trusts and includes vested equity settled stock-based compensation

awards other than stock options. Diluted earnings per share is calculated using the weighted-average number of diluted shares outstanding

during the period, applying the treasury stock method. The weighted-average number of diluted shares outstanding includes the dilutive effects

of common shares issuable upon exercise of outstanding stock options and nonvested equity settled awards.

Foreign currency

All of the Company's foreign subsidiaries use the US dollar as their functional currency. Accordingly, the foreign subsidiaries' assets and

liabilities are translated into Canadian dollars at the exchange rate in effect at the balance sheet date and the revenues and expenses are

translated at the average exchange rates during the year. All adjustments resulting from the translation of the foreign operations are recorded in

Other comprehensive income (loss).

The Company designates the US dollar-denominated debt of the parent company as a foreign currency hedge of its net investment in

foreign operations. Accordingly, foreign exchange gains and losses, from the dates of designation, on the translation of the US dollar-

denominated debt are included in Other comprehensive income (loss).

Cash and cash equivalents

Cash and cash equivalents include highly liquid investments purchased three months or less from maturity and are stated at cost plus accrued

interest, which approximates fair value.

64 CN | 2019 Annual Report


Notes to the Consolidated Financial Statements
Restricted cash and cash equivalents
The Company has the option, under its bilateral letter of credit facility agreements with various banks, to pledge collateral in the form of cash
and cash equivalents for a minimum term of one month, equal to at least the face value of the letters of credit issued. Restricted cash and cash
equivalents include highly liquid investments purchased three months or less from maturity and are stated at cost plus accrued interest, which
approximates fair value.
Accounts receivable
Accounts receivable are recorded at cost net of billing adjustments and an allowance for doubtful accounts. The allowance for doubtful
accounts is based on expected collectability and considers historical experience as well as known trends or uncertainties related to account
collectability. When a receivable is deemed uncollectible, it is written off against the allowance for doubtful accounts. Subsequent recoveries of
amounts previously written off are credited to bad debt expense in Casualty and other in the Consolidated Statements of Income.
Material and supplies
Material and supplies, which consist mainly of rail, ties, and other items for construction and maintenance of property and equipment, as well
as diesel fuel, are measured at weighted-average cost.
Properties
Capitalization of costs
The Company's railroad operations are highly capital intensive. The Company's properties mainly consist of homogeneous or network-type
assets such as rail, ties, ballast and other structures, which form the Company's Track and roadway properties, and Rolling stock. The
Company's capital expenditures are for the replacement of existing assets and for the purchase or construction of new assets to enhance
operations or provide new service offerings to customers. A large portion of the Company's capital expenditures are for self-constructed
properties, including the replacement of existing track and roadway assets and track line expansion, as well as major overhauls and large
refurbishments of rolling stock.
Expenditures are capitalized if they extend the life of the asset or provide future benefits such as increased revenue-generating capacity,
functionality or service capacity. The Company has a process in place to determine whether or not costs qualify for capitalization, which
requires judgment. For Track and roadway properties, the Company establishes basic capital programs to replace or upgrade the track
infrastructure assets which are capitalized if they meet the capitalization criteria.
In addition, for Track and roadway properties, expenditures that meet the minimum level of activity as defined by the Company are also
capitalized as follows:
•	grading: installation of road bed, retaining walls, and drainage structures;
•	rail and related track material: installation of 39 or more continuous feet of rail;
•	ties: installation of 5 or more ties per 39 feet; and
•	ballast: installation of 171 cubic yards of ballast per mile.
For purchased assets, the Company capitalizes all costs necessary to make the assets ready for their intended use. For self-constructed
properties, expenditures include direct material, labor, and contracted services, as well as other allocated costs. These allocated costs include,
but are not limited to, project supervision, fringe benefits, maintenance on equipment used on projects as well as the cost of small tools and
supplies. The Company reviews and adjusts its allocations, as required, to reflect the actual costs incurred each year.
For the rail asset, the Company capitalizes the costs of rail grinding which consists of restoring and improving the rail profile and removing
irregularities from worn rail to extend the service life. The service life of the rail asset is increased incrementally as rail grinding is performed
thereon, and as such, the costs incurred are capitalized given that the activity extends the service life of the rail asset beyond its original or
current condition as additional gross tons can be carried over the rail for its remaining service life.
For the ballast asset, the Company engages in shoulder ballast undercutting that consists of removing some or all of the ballast, which has
deteriorated over its service life, and replacing it with new ballast. When ballast is installed as part of a shoulder ballast undercutting project, it
represents the addition of a new asset and not the repair or maintenance of an existing asset. As such, the Company capitalizes expenditures
related to shoulder ballast undercutting given that an existing asset is retired and replaced with a new asset. Under the group method of
accounting for properties, the deteriorated ballast is retired at its historical cost.
Costs of deconstruction and removal of replaced assets, referred to herein as dismantling costs, are distinguished from installation costs
for self-constructed properties based on the nature of the related activity. For Track and roadway properties, employees concurrently perform
dismantling and installation of new track and roadway assets and, as such, the Company estimates the amount of labor and other costs that
are related to dismantling. The Company determines dismantling costs based on an analysis of the track and roadway installation process.
	CN \| 2019 Annual Report	65

Notes to the Consolidated Financial Statements

Expenditures relating to the Company's properties that do not meet the Company's capitalization criteria are expensed as incurred. For

Track and roadway properties, such expenditures include but are not limited to spot tie replacement, spot or broken rail replacement, physical

track inspection for detection of rail defects and minor track corrections, and other general maintenance of track infrastructure.

Depreciation

Properties are carried at cost less accumulated depreciation including asset impairment write-downs. The cost of properties, including those

under finance leases, net of asset impairment write-downs, is depreciated on a straight-line basis over their estimated service lives, measured

in years, except for rail and ballast whose service lives are measured in millions of gross tons. The Company follows the group method of

depreciation whereby a single composite depreciation rate is applied to the gross investment in a class of similar assets, despite small

differences in the service life or salvage value of individual property units within the same asset class. The Company uses approximately 40

different depreciable asset classes.

For all depreciable asset classes, the depreciation rate is based on the estimated service lives of the assets. Assessing the

reasonableness of the estimated service lives of properties requires judgment and is based on currently available information, including

periodic depreciation studies conducted by the Company. The Company's United States (U.S.) properties are subject to comprehensive

depreciation studies as required by the Surface Transportation Board (STB) and are conducted by external experts. Depreciation studies for

Canadian properties are not required by regulation and are conducted internally. Studies are performed on specific asset groups on a periodic

basis. Changes in the estimated service lives of the assets and their related composite depreciation rates are implemented prospectively.

The service life of the rail asset is based on expected future usage of the rail in its existing condition, determined using railroad industry

research and testing (based on rail characteristics such as weight, curvature and metallurgy), factoring in the rail asset's usage to date. The

annual composite depreciation rate for the rail asset is determined by dividing the estimated annual number of gross tons carried over the rail

by the estimated service life of the rail measured in millions of gross tons. The Company amortizes the cost of rail grinding over the remaining

life of the rail asset, which includes the incremental life extension generated by rail grinding.

Given the nature of the railroad and the composition of its network which is made up of homogeneous long-lived assets, it is impractical to

maintain records of specific properties at their lowest unit of property.

Retirements of assets occur through the replacement of an asset in the normal course of business, the sale of an asset or the

abandonment of a section of track. For retirements in the normal course of business, generally the life of the retired asset is within a reasonable

range of the expected useful life, as determined in the depreciation studies, and, as such, no gain or loss is recognized under the group method.

The asset's cost is removed from the asset account and the difference between its estimated historical cost and estimated related

accumulated depreciation (net of salvage proceeds and dismantling costs), if any, is recorded as an adjustment to accumulated depreciation

and no gain or loss is recognized. The estimated historical cost of the retired asset is estimated by using deflation factors or indices that

closely correlate to the properties comprising the asset classes in combination with the estimated age of the retired asset using a first-in, first-

out approach, and applying it to the replacement value of the asset.

In each depreciation study, an estimate is made of any excess or deficiency in accumulated depreciation for all corresponding asset

classes to ensure that the depreciation rates remain appropriate. The excess or deficiency in accumulated depreciation is amortized over the

remaining life of the asset class.

For retirements of depreciable properties that do not occur in the normal course of business, the historical cost, net of salvage proceeds, is

recorded as a gain or loss in income. A retirement is considered not to be in the normal course of business if it meets the following criteria: (i) it

is unusual, (ii) it is significant in amount, and (iii) it varies significantly from the retirement pattern identified through depreciation studies. A

gain or loss is recognized in Other income for the sale of land or disposal of assets that are not part of railroad operations.

Leases

The Company engages in short and long-term leases for rolling stock including locomotives and freight cars, equipment, real estate and service

contracts that contain embedded leases. The Company determines whether or not a contract contains a lease at inception. Leases with a term

of twelve months or less are not recorded by the Company on the Consolidated Balance Sheets.

Finance and operating lease right-of-use assets and liabilities are recognized based on the present value of the future lease payments over

the lease term at the commencement date. Where the implicit interest rate is not determinable from the lease, the Company uses internal

incremental borrowing rates by tenor and currency to initially measure leases in excess of twelve months on the Consolidated Balance Sheets.

Operating lease expense is recognized on a straight-line basis over the lease term.

The Company's lease contracts may contain termination, renewal, and/or purchase options, residual value guarantees, or a combination

thereof, all of which are evaluated by the Company on a quarterly basis. The majority of renewal options available extend the lease term from

one to five years. The Company accounts for such contract options when the Company is reasonably certain that it will exercise one of these

options.

66 CN | 2019 Annual Report


Notes to the Consolidated Financial Statements
Lease contracts may contain lease and non-lease components that the Company generally accounts for separately, with the exception of
the freight car asset category for which the Company has elected to not separate the lease and non-lease components.
Intangible assets
Intangible assets consist mainly of customer contracts and relationships acquired through business acquisitions. Intangible assets are
generally amortized on a straight-line basis over their expected useful lives, ranging from 20 to 50 years. If a change in the estimated useful life
of an intangible asset is determined, amortization is adjusted prospectively.
For the purpose of impairment testing, the Company tests the recoverability of its intangible assets held and used whenever events or
changes in circumstances indicate that the carrying amount may not be recoverable, based on future undiscounted cash flows. If the carrying
amount of an intangible asset is not recoverable and exceeds the fair value, an impairment loss is recognized for the amount by which the
carrying amount of the asset exceeds the fair value.
Goodwill
The Company recognizes goodwill as the excess of the purchase price over the fair value of identifiable net assets acquired in business
combinations. Goodwill is assigned to the reporting units that are expected to benefit from the business acquisition. The carrying amount of
goodwill is not amortized; instead, it is tested for impairment annually as of the first day of the fiscal fourth quarter or more frequently if events
or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than the carrying amount.
For the purpose of impairment testing, the Company may first assess certain qualitative factors to determine if it is more likely than not
that the fair value of a reporting unit is less than its carrying amount, including goodwill, or proceed directly to a quantitative goodwill
impairment test. Qualitative factors include but are not limited to, economic, market and industry conditions, cost factors and overall financial
performance of the reporting unit, and events such as changes in management or customers. If the qualitative assessment indicates that it is
more likely than not that the fair value of a reporting unit is less than its carrying amount, the quantitative impairment test must be performed.
The quantitative impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, including goodwill, and
an impairment loss is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value, up to the value of
goodwill. The Company defines the fair value of a reporting unit as the price that would be received to sell the reporting unit as a whole in an
orderly transaction between market participants as of the impairment date. To determine the fair value of a reporting unit, the Company uses
the discounted cash flow method using the pre-tax discount rate that reflects current market assessments of the time value of money and the
risks specific to the asset or group of assets.
Accounts receivable securitization
Based on the structure of its accounts receivable securitization program, the Company accounts for the proceeds received as secured
borrowings.
Pensions
Pension costs are determined using actuarial methods. Net periodic benefit cost (income) includes the current service cost of pension benefits
provided in exchange for employee service rendered during the year, which is recorded in Labor and fringe benefits expense. Net periodic
benefit cost (income) also includes the following, which are recorded in Other components of net periodic benefit income (cost):
•	the interest cost of pension obligations;
•	the expected long-term return on pension fund assets;
•	the amortization of prior service costs and amendments over the expected average remaining service life of the employee group covered
by the plans; and
•	the amortization of cumulative net actuarial gains and losses in excess of 10% of the greater of the beginning of year balances of the
projected benefit obligation or market-related value of plan assets, over the expected average remaining service life of the employee group
covered by the plans.
The pension plans are funded through contributions determined in accordance with the projected unit credit actuarial cost method.
Postretirement benefits other than pensions
The Company accrues the cost of postretirement benefits other than pensions using actuarial methods. These benefits, which are funded as
they become due, include life insurance programs, medical benefits and, for a closed group of employees, free rail travel benefits.
The Company amortizes the cumulative net actuarial gains and losses in excess of 10% of the projected benefit obligation at the beginning
of the year, over the expected average remaining service life of the employee group covered by the plan.
	CN \| 2019 Annual Report	67


Notes to the Consolidated Financial Statements Additional paid-in capital
Additional paid-in capital includes the stock-based compensation expense on equity settled awards and other items relating to equity settled
awards. Upon the exercise of stock options, the stock-based compensation expense related to those awards is reclassified from Additional
paid-in capital to Common shares. Upon settlement of all other equity settled awards, the Company reclassifies from Additional paid-in capital
to Retained Earnings the excess, if any, of the settlement cost of the awards over the related stock-based compensation expense, with no
adjustment to common shares.
Stock-based compensation
For equity settled awards, stock-based compensation costs are accrued over the requisite service period based on the fair value of the awards
at the grant date. The grant date fair value of performance share unit (PSU) awards is dependent on the type of PSU award. The grant date fair
value of PSU-ROIC awards is determined using a lattice-based model incorporating a minimum share price condition and the grant date fair
value of PSU-TSR awards is determined using a Monte Carlo simulation model. The grant date fair value of equity settled deferred share unit
(DSU) awards is determined using the stock price at the grant date. The grant date fair value of stock option awards is determined using the
Black-Scholes option-pricing model. For cash settled awards, stock-based compensation costs are accrued over the requisite service period
based on the fair value determined at each period-end. The fair value of cash settled DSU awards is determined using their intrinsic value.
Personal injury and other claims
In Canada, the Company accounts for costs related to employee work-related injuries based on actuarially developed estimates on a discounted
basis of the ultimate cost associated with such injuries, including compensation, health care and third-party administration costs. In the U.S.,
the Company accrues the expected cost for personal injury, property damage and occupational disease claims, based on actuarial estimates of
their ultimate cost on an undiscounted basis. For all other legal actions in Canada and the U.S., the Company maintains, and regularly updates
on a case-by-case basis, provisions for such items when the expected loss is both probable and can be reasonably estimated based on
currently available information.
Environmental expenditures
Environmental expenditures that relate to current operations, or to an existing condition caused by past operations, are expensed as incurred.
Environmental expenditures that provide a future benefit are capitalized. Environmental liabilities are recorded when environmental
assessments occur, remedial efforts are probable, and when the costs, based on a specific plan of action in terms of the technology to be used
and the extent of the corrective action required, can be reasonably estimated. The Company accrues its allocable share of liability taking into
account the Company's alleged responsibility, the number of potentially responsible parties and their ability to pay their respective shares of the
liability. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.
Derivative financial instruments
The Company uses derivative financial instruments from time to time in the management of its interest rate and foreign currency exposures.
Derivative instruments are recorded on the balance sheet at fair value. The changes in fair value of derivative instruments not designated or not
qualified as a hedge are recorded in Net income in the current period.
2 – Recent accounting pronouncements
The following recent Accounting Standards Updates (ASUs) issued by FASB were adopted by the Company during the current year:
ASU 2016-02 Leases and related amendments (Topic 842)
The ASU requires a lessee to recognize a right-of-use asset and a lease liability on the balance sheet for all leases greater than twelve months
and requires additional qualitative and quantitative disclosures. The lessor accounting model under the new standard is substantially
unchanged. The guidance must be applied using a modified retrospective approach. Entities may elect to apply the guidance to each prior
period presented with a cumulative-effect adjustment to retained earnings recognized at the beginning of the earliest period presented or to
apply the guidance with a cumulative-effect adjustment to retained earnings recognized at the beginning of the period of adoption.
The new standard provides a number of practical expedients and accounting policy elections upon transition. On January 1, 2019, the
Company did not elect the package of three practical expedients that permits the Company not to reassess prior conclusions about lease
qualification, classification and initial direct costs. Upon adoption, the Company elected the following practical expedients:
•	the use-of-hindsight practical expedient to reassess the lease term and the likelihood that a purchase option will be exercised;
•	the land easement practical expedient to not evaluate land easements that were not previously accounted for as leases under Topic 840;
68 CN \| 2019 Annual Report


Notes to the Consolidated Financial Statements
•	the short-term lease exemption for all asset classes that permits entities not to recognize right-of-use assets and lease liabilities onto the
balance sheet for leases with terms of twelve months or less; and
•	the practical expedient to not separate lease and non-lease components for the freight car asset category.
The Company adopted this standard in the first quarter of 2019 with an effective date of January 1, 2019 using a modified retrospective
approach with a cumulative-effect adjustment to Retained earnings recognized on January 1, 2019, with no restatement of comparative period
financial information. As at January 1, 2019, the cumulative-effect adjustment to adopt the new standard increased the balance of Retained
earnings by $29 million, relating to a deferred gain on a sale-leaseback transaction of a real estate property. The initial adoption transition
adjustment to record right-of-use assets and lease liabilities for leases over twelve months on the Company's Consolidated Balance Sheet was
$756 million to each balance. The initial adoption transition adjustment is comprised of finance and operating leases of $215 million and $541
million, respectively. New finance lease right-of-use assets and finance lease liabilities are a result of the reassessment of leases with purchase
options that are reasonably certain to be exercised by the Company under the transition to Topic 842, previously accounted for as operating
leases.
ASU 2017-04 Intangibles - Goodwill and other (Topic 350): Simplifying the test for goodwill impairment
The ASU simplifies the goodwill impairment test by removing the requirement to compare the implied fair value of goodwill with its carrying
amount. Under the new standard, goodwill impairment tests are performed by comparing the fair value of a reporting unit with its carrying
amount, recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, up to the value
of goodwill.
The guidance must be applied prospectively. The ASU is effective for annual and any interim impairment tests for periods beginning after
December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1,
2017.
The Company adopted this standard in the first quarter of 2019 with an effective date of January 1, 2019. The adoption of this standard did
not have an impact on the Company’s Consolidated Financial Statements.
The following recent ASUs issued by FASB have an effective date after December 31, 2019 and have not been adopted by the Company:
ASU 2019-12 Income taxes (Topic 740): Simplifying the accounting for income taxes
The ASU adds new guidance to simplify accounting for income taxes, changes the accounting for certain income tax transactions and makes
minor improvements to the codification. The ASU introduces new guidance that provides a policy election to not allocate consolidated income
taxes when a member of a consolidated tax return is not subject to income tax, and provides guidance to evaluate whether a step-up in tax
basis of goodwill relates to a business combination in which book goodwill was recognized or a separate transaction. In addition, the ASU
changes the current guidance by making an intraperiod allocation if there is a loss in continuing operations and gains outside of continuing
operations; by determining when a deferred tax liability is recognized after an investor in a foreign entity transitions to or from the equity
method of accounting; by accounting for tax law changes and year-to-date losses in interim periods; and by determining how to apply the
income tax guidance to franchise taxes and other taxes that are partially based on income.
The ASU is effective for annual and any interim period beginning after December 15, 2020. Early adoption is permitted.
The Company is evaluating the effects that the adoption of the ASU will have on its Consolidated Financial Statements; no significant
impact is expected.
ASU 2016-13 Financial instruments - Credit losses (Topic 326): Measurement of credit losses on financial instruments
The ASU requires financial assets measured at amortized cost to be presented at the net amount expected to be collected. The new standard
replaces the current incurred loss impairment methodology with one that reflects expected credit losses. The adoption of the ASU is not
expected to have a significant impact on the Company’s Consolidated Financial Statements. CN will adopt the requirements of the ASU
effective January 1, 2020.
Other recently issued ASUs required to be applied for periods beginning on or after January 1, 2020 have been evaluated by the Company and
will not have a significant impact on the Company's Consolidated Financial Statements.

Acquisition of the TransX Group of Companies
On March 20, 2019, the Company acquired the Manitoba-based TransX Group of Companies ("TransX"). TransX provides various transportation
and logistics services, including intermodal, truckload, less than truckload and specialized services. The acquisition positions CN to strengthen
its intermodal business, and allows the Company to expand capacity and foster additional supply chain solutions. The acquisition was subject
to a number of conditions, including regulatory review by the Competition Bureau Canada and Canada’s Ministry of Transportation. On March
18, 2019, the Competition Bureau Canada issued a No Action Letter, satisfying the only outstanding condition and allowing the Company to
close the transaction.
The Company's Consolidated Balance Sheet includes the assets and liabilities of TransX as of March 20, 2019, the acquisition date. Since
the acquisition date, TransX's results of operations have been included in the Company's results of operations. The Company has not provided
pro forma information relating to the pre-acquisition period as it was not material.
The total purchase price of $192 million included an initial cash payment of $170 million, additional consideration of $25 million, less an
adjustment of $3 million in the fourth quarter of 2019 to reflect the settlement of working capital. The acquisition date fair value of the
additional consideration, recorded as a contingent liability, was estimated based on the expected outcome of operational and financial targets,
and remained unchanged since the acquisition date. The fair value measure was based on Level 3 inputs not observable in the market. On
August 27, 2019, the additional consideration was paid.

Disposal of property
2018
Guelph
On November 15, 2018, the Company recorded a gain of $79 million ($70 million after-tax) in Other income upon transfer of control of a
segment of the Guelph subdivision located between Georgetown and Kitchener, Ontario, together with the rail fixtures and certain passenger
agreements (the “Guelph”). The gain recognized in 2018 was previously deferred from a 2014 transaction at which time the Company did not
transfer control.
Doney and St-Francois Spurs
On September 5, 2018, the Company completed the sale of property located in Montreal, Quebec (the “Doney and St-Francois Spurs”) for cash
proceeds of $40 million. The transaction resulted in a gain of $36 million ($32 million after-tax) that was recorded in Other income on that date.
Central Station Railway Lease
On April 9, 2018, the Company completed the transfer of its finance lease in the passenger rail facilities in Montreal, Quebec, together with its
interests in related railway operating agreements (the “Central Station Railway Lease”), for cash proceeds of $115 million. The transaction
resulted in a gain of $184 million ($156 million after-tax) that was recorded in Other income on that date. The gain includes the difference
between the net book value of the asset and the cash proceeds, the extinguishment of the finance lease obligation, and the recognition of a
gain previously deferred from a sale-leaseback transaction.
Calgary Industrial Lead
On April 6, 2018, the Company completed the sale of land located in Calgary, Alberta, excluding the rail fixtures (the “Calgary Industrial Lead”),
for cash proceeds of $39 million. The transaction resulted in a gain of $39 million ($34 million after-tax) that was recorded in Other income on
that date.

6 – Income taxes
The Company's consolidated effective income tax rate differs from the Canadian, or domestic, statutory federal tax rate. The effective tax rate is
affected by recurring items in provincial, U.S. federal, state and other foreign jurisdictions, such as tax rates and the proportion of income
earned in those jurisdictions. The effective tax rate is also affected by discrete items such as income tax rate enactments, and lower corporate
income tax rates on capital dispositions that may occur in any given year.
On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act ("U.S. Tax Reform"). The U.S. Tax
Reform reduces the U.S. federal corporate income tax rate from 35% to 21%, effective as of January 1, 2018. The U.S. Tax Reform also allows
for immediate capital expensing of new investments in certain qualified depreciable assets made after September 27, 2017, which will be
phased down starting in year 2023. As a result of the U.S. Tax Reform, the Company's net deferred income tax liability decreased by $1,764
million for the year ended December 31, 2017.
The U.S. Tax Reform introduced other important changes to U.S. corporate income tax laws including the creation of a new Base Erosion
Anti-abuse Tax (BEAT) that subjects certain payments from U.S. corporations to foreign related parties to additional taxes and limitations to the
deduction for net interest expense incurred by U.S. corporations. Since the enactment of the U.S. Tax Reform, U.S. authorities have issued
various proposed and finalized regulations and guidance interpreting its provisions. These interpretations have been taken into account in
calculating the Company's current year income tax provision and tax payments. The U.S. Tax Reform and these regulations are expected to
impact the Company's income tax provisions and tax payments in future years.

(1)	At December 31, 2019, the Company has $937 million net operating loss carryforwards for U.S. federal income tax purposes that arose in 2019, over an indefinite period.The utilization of those U.S. federal net operating loss carryforwards is limited to 80% of taxable income in any given year, as prescribed under the provisions of the U.S. TaxReform. In addition, the Company has net operating loss carryforwards of $177 million for U.S. state tax purposes, which are available to offset future U.S. state taxableincome between the years 2020 and 2039.
On an annual basis, the Company assesses the need to establish a valuation allowance for its deferred income tax assets, and if it is
deemed more likely than not that its deferred income tax assets will not be realized, a valuation allowance is recorded. The ultimate realization
of deferred income tax assets is dependent upon the generation of future taxable income, of the necessary character, during the periods in
which those temporary differences become deductible. Management considers the scheduled reversals of deferred income tax liabilities, the
available carryback and carryforward periods, and projected future taxable income in making this assessment. As at December 31, 2019, in
order to fully realize all of the deferred income tax assets, the Company will need to generate future taxable income of approximately $3.0
billion, and, based upon the level of historical taxable income, projections of future taxable income of the necessary character over the periods in which the deferred income tax assets are deductible, and the reversal of taxable temporary differences, management believes, following an
assessment of the current economic environment, it is more likely than not that the Company will realize the benefits of these deductible
differences. As at December 31, 2019, the Company has not recognized a deferred income tax asset of $244 million (2018 - $217 million) on
the unrealized foreign exchange loss recorded in Accumulated other comprehensive loss relating to its net investment in U.S. subsidiaries, as
the Company does not expect this temporary difference to reverse in the foreseeable future.

Net unrecognized tax benefits at end of year					$	60	$	69	$	69
As at December 31, 2019, the total amount of gross unrecognized tax benefits was $62 million, before considering tax treaties and other
arrangements between taxation authorities. The amount of net unrecognized tax benefits as at December 31, 2019 was $60 million. If
recognized, $7 million of the net unrecognized tax benefits as at December 31, 2019 would affect the effective tax rate. The Company believes
that it is reasonably possible that $23 million of the net unrecognized tax benefits as at December 31, 2019 related to Canadian federal and
provincial income tax matters, may be recognized over the next twelve months as a result of settlements and a lapse of the applicable statute
of limitations, and will not affect the effective tax rate as they relate to temporary differences.
The Company recognizes accrued interest and penalties related to gross unrecognized tax benefits in Income tax expense in the
Company's Consolidated Statements of Income. For the year ended December 31, 2019, the Company recognized accrued interest and
penalties of $1 million (2018 - $3 million; 2017 - $3 million). As at December 31, 2019, the Company had accrued interest and penalties of $11
million (2018 - $10 million).
In Canada, the Company's federal and provincial income tax returns filed for the years 2014 to 2018 remain subject to examination by the
taxation authorities. An examination of the Company's federal income tax returns for the years 2014 and 2015 is currently in progress and is
expected to be completed during 2020. In the U.S., the federal income tax returns filed for the years 2016 to 2018 and the state income tax
returns filed for the years 2015 to 2018 remain subject to examination by the taxation authorities. During the year, the Company settled certain
state tax audits which resulted in the recognition of tax benefits. Examination of the Company's U.S. federal income tax return for the year 2017
as well as examinations of certain state income tax returns are currently in progress. The Company does not anticipate any significant impacts
to its results of operations or financial position as a result of the final resolutions of such matters.

Revolving credit facility
The Company has an unsecured revolving credit facility with a consortium of lenders, which is available for general corporate purposes,
including backstopping the Company's commercial paper programs. On March 15, 2019, the Company's revolving credit facility agreement was
amended, which extended the term of the credit facility by one year and increased the credit facility from $1.8 billion to $2.0 billion, effective
May 5, 2019. The amended credit facility of $2.0 billion consists of a $1.0 billion tranche maturing on May 5, 2022 and a $1.0 billion tranche
maturing on May 5, 2024. Under the amended credit facility, the Company has the option to request an extension once a year to maintain the
tenors of three years and five years of the respective tranches subject to the consent of the individual lenders. The accordion feature, which
provides for an additional $500 million of credit under the facility, remains unchanged. The credit facility agreement contains customary terms
and conditions, which were substantially unchanged by the amendment. The credit facility provides for borrowings at various benchmark
interest rates, plus applicable margins, based on CN's debt credit ratings. The credit facility agreement has one financial covenant, which limits
debt as a percentage of total capitalization, and with which the Company is in compliance.

15 – Pensions and other postretirement benefits

The Company has various retirement benefit plans under which substantially all of its employees are entitled to benefits at retirement age,

generally based on compensation and length of service and/or contributions. Senior and executive management employees, subject to certain

minimum service and age requirements, are also eligible for an additional retirement benefit under their Special Retirement Stipend

Agreements, the Supplemental Executive Retirement Plan or the Defined Contribution Supplemental Executive Retirement Plan.

The Company also offers postretirement benefits to certain employees providing life insurance, medical benefits and, for a closed group of

employees, free rail travel benefits during retirement. These postretirement benefits are funded as they become due. The information in the

tables that follow pertains to all of the Company's defined benefit plans. However, the following descriptions relate solely to the Company's

main pension plan, the CN Pension Plan, unless otherwise specified.

Description of the CN Pension Plan

The CN Pension Plan is a contributory defined benefit pension plan that covers the majority of CN employees. It provides for pensions based

mainly on years of service and final average pensionable earnings and is generally applicable from the first day of employment. Indexation of

pensions is provided after retirement through a gain/loss sharing mechanism, subject to guaranteed minimum increases. An independent trust

company is the Trustee of the Company's pension trust funds (which includes the CN Pension Trust Fund). As Trustee, the trust company

performs certain duties, which include holding legal title to the assets of the CN Pension Trust Fund and ensuring that the Company, as

Administrator, complies with the provisions of the CN Pension Plan and the related legislation. The Company utilizes a measurement date of

December 31 for the CN Pension Plan.

Funding policy

Employee contributions to the CN Pension Plan are determined by the plan rules. Company contributions are in accordance with the

requirements of the Government of Canada legislation, the Pension Benefits Standards Act, 1985, including amendments and regulations

thereto, and such contributions follow minimum and maximum thresholds as determined by actuarial valuations. Actuarial valuations are

generally required on an annual basis for all Canadian defined benefit pension plans, or when deemed appropriate by the Office of the

Superintendent of Financial Institutions. These actuarial valuations are prepared in accordance with legislative requirements and with the

recommendations of the Canadian Institute of Actuaries for the valuation of pension plans. Actuarial valuations are also required annually for

the Company's U.S. qualified defined benefit pension plans.

The Company's most recently filed actuarial valuations for funding purposes for its Canadian registered defined benefit pension plans

conducted as at December 31, 2018 indicated a funding excess on a going concern basis of approximately $3.3 billion and a funding excess on

a solvency basis of approximately $0.5 billion, calculated using the three-year average of the plans' hypothetical wind-up ratio in accordance

with the Pension Benefit Standards Regulations, 1985. The federal pension legislation requires funding deficits, if any, to be paid over a number

of years, as calculated under current pension regulations. Alternatively, a letter of credit can be subscribed to fulfill required solvency deficit

payments.

The Company's next actuarial valuations for funding purposes for its Canadian registered defined benefit pension plans required as at

December 31, 2019 will be performed in 2020. These actuarial valuations are expected to identify a funding excess on a going concern basis of

approximately $3.5 billion, while on a solvency basis a funding excess of approximately $0.5 billion is expected. Based on the anticipated

results of these valuations, the Company expects to make total cash contributions of approximately $135 million for all of the Company's

pension plans in 2020. As at January 31, 2020 the Company had contributed $59 million to its defined benefit pension plans for 2020.

84 CN | 2019 Annual Report


Notes to the Consolidated Financial Statements Plan assets
The assets of the Company's various Canadian defined benefit pension plans are primarily held in separate trust funds ("Trusts") which are
diversified by asset type, country, sector and investment strategy. Each year, the CN Board of Directors reviews and confirms or amends the
Statement of Investment Policies and Procedures ("SIPP") which includes the plans' long-term target asset allocation ("Policy") and related
benchmark indices. This Policy is based on the long-term expectations of the economy and financial market returns and considers the
dynamics of the plans' pension benefit obligations. In 2019, the Policy was amended to affect a target asset allocation change to bonds and
mortgages, emerging market debt, private debt, absolute return and investment-related liabilities.
The CN Investment Division ("Investment Manager"), a division of the Company created to invest and administer the assets of the plan, can
also implement an investment strategy ("Strategy") which can lead the Plan's actual asset allocation to deviate from the Policy due to changing
market risks and opportunities. The Pension and Investment Committee of the Board of Directors ("Committee") regularly compares the actual
plan asset allocation to the Policy and Strategy and compares the actual performance of the Company's pension plan assets to the
performance of the benchmark indices.
The Company's 2019 Policy and actual asset allocation for the Company's pension plans based on fair value are as follows:
	Actual plan asset allocation
		Policy	2019	2018
Cash and short-term investments		3 %	3 %	3%
Bonds and mortgages					(1)	35 %	36 %	35%
Emerging market debt					(1)	1.5 %	3 %	3%
Private debt						(1)	1.5 %	3 %	2%
Equities		40 %	37 %	33%
Real estate		4 %	2 %	2%
Oil and gas		7 %	5 %	6%
Infrastructure						(1)	4 %	3 %	4%
Absolute return		10 %	10 %	10%
Risk-factor allocation		— %	1 %	2%
Investment-related liabilities		(6)%	(3)%	—%
Total		100 %	100 %			100%
(1)	Certain assets in the 2018 comparative figures have been reclassified from bonds and mortgages and infrastructure to emerging market debt and private debt, respectively,to conform to the current year's presentation.
The Committee's approval is required for all major investments in illiquid securities. The SIPP allows for the use of derivative financial
instruments to implement strategies, hedge and adjust existing or anticipated exposures. The SIPP prohibits investments in securities of the
Company or its subsidiaries. Investments held in the Company's pension plans consist mainly of the following:
•	Cash and short-term investments consist of highly liquid securities which ensure adequate cash flows are available to cover near-term
benefit payments. Short-term investments are mainly obligations issued by Canadian chartered banks.
•	Bonds include bond instruments, issued or guaranteed by governments and non-government entities. As at December 31, 2019, 80% (2018
- 80%) of bonds were issued or guaranteed by Canadian, U.S. or other governments. Mortgages consist of mortgage products which are
primarily conventional or participating loans secured by commercial properties. On an exposure basis, the Plan's policy reflects an
allocation of 45%, comprising a 35% allocation to bonds and mortgages investments and a 10% allocation to derivative financial
instruments.
•	Emerging market debt consists of units invested in mainly open-ended funds whose mandate is to invest in debt instruments of emerging
market countries.
•	Private debt includes participations in private debt funds focused on generating steady yields.
•	Equity investments include publicly traded securities diversified by industry sector, country and issuer and investments in mainly energy
related private equity funds. As at December 31, 2019, the most significant allocation to an individual issuer of a publicly traded security
was 1% (2018 - 2%) and the most significant allocation to an industry sector was 12% (2018 - 22%).
•	Real estate is a diversified portfolio of Canadian land and commercial properties and investments in real estate private equity funds.
•	Oil and gas investments include petroleum and natural gas properties and listed and non-listed securities of oil and gas companies.
•	Infrastructure investments include participations in private infrastructure funds, term loans and notes of infrastructure companies.
•	Absolute return investments are primarily a portfolio of units of externally managed hedge funds, which are invested in various long/short
strategies within multi-strategy, fixed income, equity and global macro funds. Managers are monitored on a continuous basis through
investment and operational due diligence.
	CN \| 2019 Annual Report			85


Notes to the Consolidated Financial Statements
•	Risk-factor allocation investments are a portfolio of units of externally managed funds and internally managed strategies in order to
capture alternative risk premia.
•	Investment-related liabilities include a certain level of financing associated with securities sold under repurchase agreements and other
assets.
The plans' Investment Manager monitors market events and risk exposures to foreign currencies, interest rates, market risks, credit risks
and liquidity risks daily. When investing in foreign securities, the plans are exposed to foreign currency risk that may be adjusted or hedged; the
effect of which is included in the valuation of the foreign securities. Net of the adjusted or hedged amount, the plans were 60% exposed to the
Canadian dollar, 21% to the US dollar, 9% to European currencies, 3% to the Japanese Yen and 7% to various other currencies as at December
31, 2019. Interest rate risk represents the risk that the fair value of the investments will fluctuate due to changes in market interest rates.
Sensitivity to interest rates is a function of the timing and amount of cash flows of the interest-bearing assets and liabilities of the plans.
Derivatives are used from time to time to adjust the plan asset allocation or exposures to interest rates, foreign currencies, market risks or
commodity prices of the portfolio or anticipated transactions. Derivatives are contractual agreements whose value is derived from interest
rates, foreign exchange rates, and equity or commodity prices. They may include forwards, futures, options and swaps and are included in
investment categories based on their underlying exposure. When derivatives are used for hedging purposes, the gains or losses on the
derivatives are offset by a corresponding change in the value of the hedged assets. To manage credit risk, established policies require dealing
with counterparties considered to be of high credit quality. Adequate liquidity is maintained to cover cash flows by monitoring factors such as
fair value, collateral pledged and received, repurchase agreements and securities lending agreements.
Overall return in the capital markets and the level of interest rates affect the funded status of the Company's pension plans, particularly the
Company's main Canadian pension plan. Adverse changes with respect to pension plan returns and the level of interest rates from the date of
the last actuarial valuations may have a material adverse effect on the funded status of the plans and on the Company's results of operations.

(2)	Bonds are valued using mid-market prices obtained from independent pricing data suppliers. When prices are not available from independent sources, the fair value isbased on the present value of future cash flows using current market yields for comparable instruments.
(3)	Emerging market debt funds are valued based on the net asset value which is readily available and published by each fund's independent administrator.
(4)	Mortgages are valued based on the present value of future net cash flows using current market yields for comparable instruments.
(5)	Private debt investments are valued based on the net asset value as reported by each fund's manager, generally based on the present value of future net cash flows usingcurrent market yields for comparable instruments.
(6)	The fair value of public equity investments is based on quoted prices in active markets for identical assets.
(7)	Private equity investments are valued based on the net asset value as reported by each fund's manager, generally using discounted cash flow analysis or earningsmultiples.
(8)	The fair value of real estate investments categorized as Level 3 includes immoveable properties. Land is valued based on the fair value of comparable assets, and incomeproducing properties are valued based on the present value of estimated future net cash flows or the fair value of comparable assets. Independent valuations of allimmoveable properties are performed triennially on a rotational basis. The fair value of real estate investments categorized as NAV consists mainly of investments in realestate private equity funds and is based on the net asset value as reported by each fund's manager, generally using a discounted cash flow analysis or earnings multiples.
(9)	Oil and gas investments categorized as Level 1 are valued based on quoted prices in active markets. Oil and gas participations traded on a secondary market are valuedbased on the most recent transaction price and are categorized as Level 2. Investments in oil and gas categorized as Level 3 consist of operating oil and gas properties andthe fair value is based on estimated future net cash flows that are discounted using prevailing market rates for transactions in similar assets. Estimated future net cashflows are based on forecasted oil and gas prices and projected annual production and costs.
(10) The fair value of infrastructure investments categorized as Level 2 is based on the present value of future cash flows using current market yields for comparable
instruments. The fair value of infrastructure funds categorized as NAV is based on the net asset value as reported by each fund's manager, generally using a discountedcash flow analysis or earnings multiples.
(11) Absolute return investments are valued using the net asset value as reported by each fund's independent administrator. All absolute return investments have contractual

valuation techniques using market data, when quoted market prices are not available and are categorized as Level 2. Derivatives are included in the investment assetcategories based on their underlying exposure.
(14) Investment-related liabilities include securities sold under repurchase agreements. The securities sold under repurchase agreement do not meet the conditions to remove
from the assets and are therefore maintained on the books with an offsetting liability recorded to represent the financing nature of this transaction. These agreements arerecorded at cost, which together with accrued interest approximates fair value due to their short-term nature.
(15) Other consists of operating assets of $108 million (2018 - $120 million) and liabilities of $107 million (2018 - $13 million) required to administer the Trusts' investment
assets and the plans' benefit and funding activities. Such assets are valued at cost and have not been assigned to a fair value category.

(1)	The Company's discount rate assumption, which is set annually at the end of each year, is determined by management with the aid of third-party actuaries. The discountrate is used to measure the single amount that, if invested at the measurement date in a portfolio of high-quality debt instruments with a rating of AA or better, wouldprovide the necessary cash flows to pay for pension benefits as they become due. For the Canadian pension and other postretirement benefit plans, future expected benefitpayments are discounted using spot rates based on a derived AA corporate bond yield curve for each maturity year.
(2)	The rate of compensation increase is determined by the Company based upon its long-term plans for such increases.
(3)	The Company uses the spot rate approach to measure current service cost and interest cost for all defined benefit pension and other postretirement benefit plans. Underthe spot rate approach, individual spot discount rates along the same yield curve used in the determination of the projected benefit obligation are applied to the relevantprojected cash flows at the relevant maturity.
(4)	The expected long-term rate of return is determined based on expected future performance for each asset class and is weighted based on the investment policy. For 2019,the Company used a long-term rate of return assumption of 7.00% on the market-related value of plan assets to compute net periodic benefit cost (income). The Companyhas elected to use a market-related value of assets, whereby realized and unrealized gains/losses and appreciation/depreciation in the value of the investments arerecognized over a period of five years, while investment income is recognized immediately. In 2020, the Company will maintain the expected long-term rate of return on planassets at 7.00% to reflect management's current view of long-term investment returns.

Share Units Plan
The objective of the Share Units Plan is to enhance the Company's ability to attract and retain talented employees and to provide alignment of
interests between such employees and the shareholders of the Company. Under the Share Units Plan, the Company grants performance share
unit (PSU) awards.
PSU-ROIC awards vest dependent upon the attainment of a target level of return on invested capital (ROIC), as defined by the award
agreement, over the plan period of three years. Such performance vesting criteria results in a performance vesting factor that ranges from 0% to
200% depending on the level of ROIC attained. Payout is conditional upon the attainment of a minimum share price, calculated using the
average of the last three months of the plan period.
PSU-TSR awards vest dependent upon the attainment of a total shareholder return (TSR) market condition over the plan period of three
years. Such performance vesting criteria result in a performance vesting factor that ranges from 0% to 200% depending on the Company's TSR
relative to a Class I Railways peer group and components of the S&P/TSX 60 Index.
PSUs are settled in common shares of the Company, subject to the attainment of their respective vesting conditions, by way of
disbursement from the Share Trusts (see Note 16 – Share capital). The number of shares remitted to the participant upon settlement is equal to
the number of PSUs awarded multiplied by the performance vesting factor less shares withheld to satisfy the participant's withholding tax
requirement.
For the 2017 grant, the level of ROIC attained resulted in a performance vesting factor of 169%, and the level of TSR attained resulted in a
performance vesting factor of 100% for the plan period ended December 31, 2019. The total fair value of the equity settled PSU awards that
vested in 2019 was $45 million (2018 - $42 million; 2017 - $43 million). As the respective vesting conditions under each plan and the minimum
share price condition for the PSU-ROIC awards were met at December 31, 2019, settlement of approximately 0.4 million shares, net of
withholding taxes, is expected to occur in the first quarter of 2020.

Notes to the Consolidated Financial Statements Voluntary Incentive Deferral Plan
The Company's Voluntary Incentive Deferral Plan (VIDP) provides eligible senior management employees the opportunity to elect to receive
their annual incentive bonus payment in deferred share units (DSU) up to specific deferral limits. A DSU is equivalent to a common share of the
Company and also earns dividends when normal cash dividends are paid on common shares. The number of DSUs received by each participant
is established at the time of deferral. For each participant, the Company will grant a further 25% of the amount elected in DSUs, which will vest
over a period of four years. The election to receive eligible incentive payments in DSUs is no longer available to a participant when the value of
the participant's vested DSUs is sufficient to meet the Company's stock ownership guidelines.
Equity settled awards
DSUs are settled in common shares of the Company at the time of cessation of employment by way of an open market purchase by the
Company. The number of shares remitted to the participant is equal to the number of DSUs awarded less shares withheld to satisfy the
participant's withholding tax requirement.
Cash settled awards
The value of each participant's DSUs is payable in cash at the time of cessation of employment.

Notes to the Consolidated Financial Statements Stock option awards
The Company's stock option plan allows for eligible employees to acquire common shares of the Company upon vesting at a price equal to the
market value of the common shares at the grant date. The options issued by the Company are conventional options that vest over a period of
time. The right to exercise options generally accrues over a period of four years of continuous employment. Options are not generally
exercisable during the first 12 months after the date of grant and expire after 10 years. As at December 31, 2019, 14.9 million common shares
remained authorized for future issuances under these plans.
During the year ended December 31, 2019, the Company granted 0.9 million (2018 - 1.1 million; 2017 - 1.0 million) stock options.

Stock price volatility
The Company's liability for the cash settled VIDP is marked-to-market at each period-end and varies with the Company's share price.
Fluctuations in the Company's share price cause volatility to stock-based compensation expense as recorded in Net income. The Company
does not currently hold any derivative financial instruments to manage this exposure.
Employee Share Investment Plan
The Company has an Employee Share Investment Plan (ESIP) giving eligible employees the opportunity to subscribe for up to 10% of their gross
salaries to purchase shares of the Company's common stock on the open market and to have the Company invest, on the employees' behalf, a
further 35% of the amount invested by the employees, up to 6% of their gross salaries.
Beginning January 1, 2019, Company contributions to the ESIP, which consist of shares purchased on the open market, are subject to a
one-year vesting period and are forfeited should certain participant contributions be sold or disposed of prior to vesting. Company contributions
to the ESIP are held in Share Trusts until vesting, at which time shares are delivered to the employee.

19 – Major commitments and contingencies

Purchase commitments

As at December 31, 2019, the Company had fixed and variable commitments to purchase rail, information technology services and licenses,

locomotives, wheels, engineering services, railroad ties, rail cars, as well as other equipment and services with a total estimated cost of $1,621

million. Costs of variable commitments were estimated using forecasted prices and volumes.

Contingencies

In the normal course of business, the Company becomes involved in various legal actions seeking compensatory and occasionally punitive

damages, including actions brought on behalf of various purported classes of claimants and claims relating to employee and third-party

personal injuries, occupational disease and property damage, arising out of harm to individuals or property allegedly caused by, but not limited

to, derailments or other accidents.

Canada

Employee injuries are governed by the workers' compensation legislation in each province whereby employees may be awarded either a lump

sum or a future stream of payments depending on the nature and severity of the injury. As such, the provision for employee injury claims is

discounted. In the provinces where the Company is self-insured, costs related to employee work-related injuries are accounted for based on

actuarially developed estimates of the ultimate cost associated with such injuries, including compensation, health care and third-party

administration costs. An actuarial study is generally performed at least on a triennial basis. For all other legal actions, the Company maintains,

and regularly updates on a case-by-case basis, provisions for such items when the expected loss is both probable and can be reasonably

estimated based on currently available information.

In 2019, 2018 and 2017 the Company recorded a decrease of $7 million, and an increase of $4 million and $2 million, respectively, to its

provision for personal injuries in Canada as a result of actuarial valuations for employee injury claims.

As at December 31, 2019, 2018 and 2017, the Company's provision for personal injury and other claims in Canada was as follows:

Current portion - End of year

United States

Personal injury claims by the Company's employees, including claims alleging occupational disease and work-related injuries, are subject to the

provisions of the Federal Employers' Liability Act (FELA). Employees are compensated under FELA for damages assessed based on a finding of

fault through the U.S. jury system or through individual settlements. As such, the provision is undiscounted. With limited exceptions where

claims are evaluated on a case-by-case basis, the Company follows an actuarial-based approach and accrues the expected cost for personal

injury, including asserted and unasserted occupational disease claims, and property damage claims, based on actuarial estimates of their

ultimate cost. An actuarial study is performed annually.

For employee work-related injuries, including asserted occupational disease claims, and third-party claims, including grade crossing,

trespasser and property damage claims, the actuarial valuation considers, among other factors, the Company's historical patterns of claims

filings and payments. For unasserted occupational disease claims, the actuarial valuation includes the projection of the Company's experience

into the future considering the potentially exposed population. The Company adjusts its liability based upon management's assessment and the

results of the study. On an ongoing basis, management reviews and compares the assumptions inherent in the latest actuarial valuation with

the current claim experience and, if required, adjustments to the liability are recorded.

Due to the inherent uncertainty involved in projecting future events, including events related to occupational diseases, which include but are not limited to, the timing and number of actual claims, the average cost per claim and the legislative and judicial environment, the

Company's future payments may differ from current amounts recorded.

In 2019, the Company recorded an increase of $2 million to its provision for U.S. personal injury and other claims attributable to third-party

claims, occupational disease claims and non-occupational disease claims pursuant to the 2019 actuarial valuation. In 2018 and 2017, actuarial

valuations resulted in an increase of $13 million and $15 million, respectively. The prior years' adjustments from the actuarial valuations were

mainly attributable to non-occupational disease claims, third-party claims and occupational disease claims reflecting changes in the Company's

estimates of unasserted claims and costs related to asserted claims. The Company has an ongoing risk mitigation strategy focused on

CN | 2019 Annual Report

Notes to the Consolidated Financial Statements

reducing the frequency and severity of claims through injury prevention and containment; mitigation of claims; and lower settlements of

existing claims.

As at December 31, 2019, 2018 and 2017, the Company's provision for personal injury and other claims in the U.S. was as follows:

Current portion - End of year

Although the Company considers such provisions to be adequate for all its outstanding and pending claims, the final outcome with respect

to actions outstanding or pending at December 31, 2019, or with respect to future claims, cannot be reasonably determined. When establishing

provisions for contingent liabilities the Company considers, where a probable loss estimate cannot be made with reasonable certainty, a range

of potential probable losses for each such matter, and records the amount it considers the most reasonable estimate within the range.

However, when no amount within the range is a better estimate than any other amount, the minimum amount in the range is accrued. For

matters where a loss is reasonably possible but not probable, a range of potential losses cannot be estimated due to various factors which may

include the limited availability of facts, the lack of demand for specific damages and the fact that proceedings were at an early stage. Based on

information currently available, the Company believes that the eventual outcome of the actions against the Company will not, individually or in

the aggregate, have a material adverse effect on the Company's financial position. However, due to the inherent inability to predict with certainty

unforeseeable future developments, there can be no assurance that the ultimate resolution of these actions will not have a material adverse

effect on the Company's results of operations, financial position or liquidity.

Environmental matters

The Company's operations are subject to numerous federal, provincial, state, municipal and local environmental laws and regulations in Canada

and the U.S. concerning, among other things, emissions into the air; discharges into waters; the generation, handling, storage, transportation,

treatment and disposal of waste, hazardous substances, and other materials; decommissioning of underground and aboveground storage

tanks; and soil and groundwater contamination. A risk of environmental liability is inherent in railroad and related transportation operations; real

estate ownership, operation or control; and other commercial activities of the Company with respect to both current and past operations.

Known existing environmental concerns

The Company is or may be liable for remediation costs at individual sites, in some cases along with other potentially responsible parties,

associated with actual or alleged contamination. The ultimate cost of addressing these known contaminated sites cannot be definitively

established given that the estimated environmental liability for any given site may vary depending on the nature and extent of the

contamination; the nature of anticipated response actions, taking into account the available clean-up techniques; evolving regulatory standards

governing environmental liability; and the number of potentially responsible parties and their financial viability. As a result, liabilities are

recorded based on the results of a four-phase assessment conducted on a site-by-site basis. A liability is initially recorded when environmental

assessments occur, remedial efforts are probable, and when the costs, based on a specific plan of action in terms of the technology to be used

and the extent of the corrective action required, can be reasonably estimated. The Company estimates the costs related to a particular site

using cost scenarios established by external consultants based on the extent of contamination and expected costs for remedial efforts. In the

case of multiple parties, the Company accrues its allocable share of liability taking into account the Company's alleged responsibility, the

number of potentially responsible parties and their ability to pay their respective share of the liability. Adjustments to initial estimates are

recorded as additional information becomes available.

The Company's provision for specific environmental sites is undiscounted and includes costs for remediation and restoration of sites, as

well as monitoring costs. Environmental expenses, which are classified as Casualty and other in the Consolidated Statements of Income,

include amounts for newly identified sites or contaminants as well as adjustments to initial estimates. Recoveries of environmental remediation

costs from other parties are recorded as assets when their receipt is deemed probable.

100 CN | 2019 Annual Report

Notes to the Consolidated Financial Statements

As at December 31, 2019, 2018 and 2017, the Company's provision for specific environmental sites was as follows:

End of year

Current portion - End of year

The Company anticipates that the majority of the liability at December 31, 2019 will be paid out over the next five years. Based on the

information currently available, the Company considers its provisions to be adequate.

Unknown existing environmental concerns

While the Company believes that it has identified the costs likely to be incurred for environmental matters based on known information, the

discovery of new facts, future changes in laws, the possibility of releases of hazardous materials into the environment and the Company's

ongoing efforts to identify potential environmental liabilities that may be associated with its properties may result in the identification of

additional environmental liabilities and related costs. The magnitude of such additional liabilities and the costs of complying with future

environmental laws and containing or remediating contamination cannot be reasonably estimated due to many factors, including:

•

the lack of specific technical information available with respect to many sites;

•

the absence of any government authority, third-party orders, or claims with respect to particular sites;

•

the potential for new or changed laws and regulations and for development of new remediation technologies and uncertainty regarding the

timing of the work with respect to particular sites; and

•

the determination of the Company's liability in proportion to other potentially responsible parties and the ability to recover costs from any

third parties with respect to particular sites.

Therefore, the likelihood of any such costs being incurred or whether such costs would be material to the Company cannot be determined at

this time. There can thus be no assurance that liabilities or costs related to environmental matters will not be incurred in the future, or will not

have a material adverse effect on the Company's financial position or results of operations in a particular quarter or fiscal year, or that the

Company's liquidity will not be adversely impacted by such liabilities or costs, although management believes, based on current information,

that the costs to address environmental matters will not have a material adverse effect on the Company's financial position or liquidity. Costs

related to any unknown existing or future contamination will be accrued in the period in which they become probable and reasonably estimable.

Future occurrences

In railroad and related transportation operations, it is possible that derailments or other accidents, including spills and releases of hazardous

materials, may occur that could cause harm to human health or to the environment. As a result, the Company may incur costs in the future,

which may be material, to address any such harm, compliance with laws and other risks, including costs relating to the performance of clean-

ups, payment of environmental penalties and remediation obligations, and damages relating to harm to individuals or property.

Regulatory compliance

The Company may incur significant capital and operating costs associated with environmental regulatory compliance and clean-up

requirements, in its railroad operations and relating to its past and present ownership, operation or control of real property. Operating expenses

related to regulatory compliance activities for environmental matters for the year ended December 31, 2019 amounted to $25 million (2018 -

$22 million; 2017 - $20 million). In addition, based on the results of its operations and maintenance programs, as well as ongoing environmental

audits and other factors, the Company plans for specific capital improvements on an annual basis. Certain of these improvements help ensure

facilities, such as fueling stations, waste water and storm water treatment systems, comply with environmental standards and include new

construction and the updating of existing systems and/or processes. Other capital expenditures relate to assessing and remediating certain

impaired properties. The Company's environmental capital expenditures for the year ended December 31, 2019 amounted to $25 million (2018 -

$19 million; 2017 - $21 million).

Guarantees and indemnifications

In the normal course of business, the Company enters into agreements that may involve providing guarantees or indemnifications to third

parties and others, which may extend beyond the term of the agreements. These include, but are not limited to, standby letters of credit, surety

and other bonds, and indemnifications that are customary for the type of transaction or for the railway business.

CN | 2019 Annual Report

101

Notes to the Consolidated Financial Statements

As at December 31, 2019, the Company had outstanding letters of credit of $424 million (2018 - $410 million) under the committed

bilateral letter of credit facilities and $149 million (2018 - $137 million) under the uncommitted bilateral letter of credit facilities, and surety and

other bonds of $169 million (2018 - $160 million), all issued by financial institutions with investment grade credit ratings to third parties to

indemnify them in the event the Company does not perform its contractual obligations.

As at December 31, 2019, the maximum potential liability under these guarantee instruments was $742 million (2018 - $707 million), of

which $681 million (2018 - $659 million) related to other employee benefit liabilities and workers' compensation and $61 million (2018 - $48

million) related to other liabilities. The guarantee instruments expire at various dates between 2020 and 2022.

As at December 31, 2019, the Company had not recorded a liability with respect to guarantees as the Company did not expect to make any

payments under its guarantees.

General indemnifications

In the normal course of business, the Company provides indemnifications, customary for the type of transaction or for the railway business, in

various agreements with third parties, including indemnification provisions where the Company would be required to indemnify third parties and

others. During the year, the Company entered into various contracts with third parties for which an indemnification was provided. Due to the

nature of the indemnification clauses, the maximum exposure for future payments cannot be reasonably determined. To the extent of any

actual claims under these agreements, the Company maintains provisions for such items, which it considers to be adequate. As at December

31, 2019, the Company had not recorded a liability with respect to any indemnifications.

20 – Financial instruments

Risk management

In the normal course of business, the Company is exposed to various risks from its use of financial instruments. To manage these risks, the

Company follows a financial risk management framework, which is monitored and approved by the Company's Finance Committee, with a goal

of maintaining a strong balance sheet, optimizing earnings per share and free cash flow, financing its operations at an optimal cost of capital

and preserving its liquidity. The Company has limited involvement with derivative financial instruments in the management of its risks and does

not hold or issue them for trading or speculative purposes.

Foreign currency risk

The Company conducts its business in both Canada and the U.S. and as a result, is affected by currency fluctuations. Changes in the exchange

rate between the Canadian dollar and the US dollar affect the Company's revenues and expenses. To manage foreign currency risk, the

Company designates US dollar-denominated debt of the parent company as a foreign currency hedge of its net investment in foreign

operations. As a result, from the dates of designation, foreign exchange gains and losses on translation of the Company's US dollar-

denominated debt are recorded in Accumulated other comprehensive loss, which minimizes volatility of earnings resulting from the conversion

of US dollar-denominated debt into the Canadian dollar.

The Company also enters into foreign exchange forward contracts to manage its exposure to foreign currency risk. As at December 31,

2019, the Company had outstanding foreign exchange forward contracts with a notional value of US$1,088 million (2018 - US$1,465 million).

Changes in the fair value of foreign exchange forward contracts, resulting from changes in foreign exchange rates, are recognized in Other

income in the Consolidated Statement of Income as they occur. For the year ended December 31, 2019, the Company recorded a loss of $75

million (2018 - gain of $157 million; 2017 - loss of $72 million) related to foreign exchange forward contracts. These gains or losses were

largely offset by the re-measurement of US dollar-denominated monetary assets and liabilities recognized in Other income. As at December 31,

2019, the fair value of outstanding foreign exchange forward contracts included in Other current assets and Accounts payable and other was

$nil and $24 million, respectively (2018 - $67 million and $nil, respectively).

Interest rate risk

The Company is exposed to interest rate risk, which is the risk that the fair value or future cash flows of a financial instrument will vary as a

result of changes in market interest rates. Such risk exists in relation to the Company's debt. The Company mainly issues fixed-rate debt, which

exposes the Company to variability in the fair value of the debt. The Company also issues debt with variable interest rates, which exposes the

Company to variability in interest expense.

To manage interest rate risk, the Company manages its borrowings in line with liquidity needs, maturity schedule, and currency and interest

rate profile. In anticipation of future debt issuances, the Company may use derivative instruments such as forward rate agreements. The

Company does not currently hold any significant derivative instruments to manage its interest rate risk.

102 CN | 2019 Annual Report


Notes to the Consolidated Financial Statements Fair value of financial instruments
The financial instruments that the Company measures at fair value on a recurring basis in periods subsequent to initial recognition are
categorized into the following levels of the fair value hierarchy based on the degree to which inputs are observable:
•	Level 1: Inputs are quoted prices for identical instruments in active markets
•	Level 2: Significant inputs (other than quoted prices included in Level 1) are observable
•	Level 3: Significant inputs are unobservable
The carrying amounts of Cash and cash equivalents and Restricted cash and cash equivalents approximate fair value. These financial
instruments include highly liquid investments purchased three months or less from maturity, for which the fair value is determined by reference
to quoted prices in active markets.
The carrying amounts of Accounts receivable, Other current assets, and Accounts payable and other approximate fair value. The fair value
of these financial instruments is not determined using quoted prices, but rather from market observable information. The fair value of derivative
financial instruments, classified as Level 2, used to manage the Company's exposure to foreign currency risk and included in Other current
assets and Accounts payable and other is measured by discounting future cash flows using a discount rate derived from market data for
financial instruments subject to similar risks and maturities.
The carrying amount of the Company's debt does not approximate fair value. The fair value is estimated based on quoted market prices for
the same or similar debt instruments, as well as discounted cash flows using current interest rates for debt with similar terms, company rating,
and remaining maturity. The Company classifies debt as Level 2. As at December 31, 2019, the Company's debt, excluding finance leases, had a
carrying amount of $13,662 million (2018 - $12,540 million) and a fair value of $15,667 million (2018 - $13,287 million).
21 – Segmented information
The Company manages its operations as one business segment over a single network that spans vast geographic distances and territories,
with operations in Canada and the U.S. Financial information reported at this level, such as revenues, operating income, and cash flow from
operations, is used by the Company's management, including its chief operating decision-maker, in evaluating financial and operational
performance and allocating resources across CN's network.
The Company's strategic initiatives, which drive its operational direction, are developed and managed centrally by management and are
communicated to its regional activity centers (the Western Region and Eastern Region). The Company's management is responsible for, among
others, CN's marketing strategy, the management of large customer accounts, overall planning and control of infrastructure and rolling stock,
the allocation of resources, and other functions such as financial planning, accounting and treasury.
The role of each region is to manage the day-to-day service requirements within their respective territories and control direct costs incurred
locally. Such cost control is required to ensure that pre-established efficiency standards set at the corporate level are met. The regions execute
the overall corporate strategy and operating plan established by the Company's management, as the regions' management of throughput and
control of direct costs does not serve as the platform for the Company's decision-making process. Approximately 95% of the Company's freight
revenues are from national accounts for which freight traffic spans North America and touches various commodity groups. As a result, the
Company does not manage revenues on a regional basis since a large number of the movements originate in one region and pass through and/
or terminate in another region.
The regions also demonstrate common characteristics in each of the following areas:
•	each region's sole business activity is the transportation of freight over the Company's extensive rail network;
•	the regions service national accounts that extend over the Company's various commodity groups and across its rail network;
•	the services offered by the Company stem predominantly from the transportation of freight by rail with the goal of optimizing the rail
network as a whole; and
•	the Company and its subsidiaries, not its regions, are subject to regulatory regimes in both Canada and the U.S.
For the years ended December 31, 2019, 2018, and 2017, no major customer accounted for more than 10% of total revenues and the
largest freight customer represented approximately 3% of total annual freight revenues.
