Notes To Financial Statements [Abstract]

Principles of consolidation

A. Principles of consolidation

These consolidated financial statements include the accounts of all subsidiaries. The Company's investments in which it has significant influence are accounted for using the equity method and all other investments are accounted for using the cost method.

Revenues

B. Revenues

Freight revenues are recognized using the percentage of completed service method based on the transit time of freight as it moves from origin to destination. The allocation of revenues between reporting periods is based on the relative transit time in each period with expenses being recorded as incurred. Revenues related to non-rail transportation services are recognized as service is performed or as contractual obligations are met. Revenues are presented net of taxes collected from customers and remitted to governmental authorities.

Foreign currency

C. Foreign currency

All of the Company's operations in the United States (U.S.) areself-contained foreign entities with the US dollar as their functional currency. Accordingly, the U.S. operations' assets and liabilities are translated into Canadian dollars at the rate in effect at the balance sheet date and the revenues and expenses are translated at average exchange rates during the year. All adjustments resulting from the translation of the foreign operations are recorded in Other comprehensive income (loss) (see Note 18 – Accumulated other comprehensive loss).

       The Company designates the US dollar-denominated long-term debt of the parent company as a foreign currency hedge of its net investment in U.S. subsidiaries. Accordingly, foreign exchange gains and losses, from the dates of designation, on the translation of the US dollar-denominated long-term debt are also included in Other comprehensive income (loss).

Cash and cash equivalents

D. Cash and cash equivalents

Cash and cash equivalents include highly liquid investments purchased three months or less from maturity and are stated at cost, which approximates market value.

Restricted cash and cash equivalents

E. 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 are shown separately on the balance sheet and include highly liquid investments purchased three months or less from maturity and are stated at cost, which approximates market value.

Accounts receivable policy

F. 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 the bad debt expense in Casualty and other in the Consolidated Statement of Income.

Material and supplies

G. 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 valued at weighted-average cost.

Properties

H. Properties

Railroad properties are carried at cost less accumulated depreciation including asset impairment write-downs. Labor, materials and other costs associated with the installation of rail, ties, ballast and other structures are capitalized to the extent they meet the Company's capitalization criteria. Major overhauls and large refurbishments of equipment are also capitalized when they result in an extension to the service life or increase the functionality of the asset. Repair and maintenance costs are expensed as incurred.

The cost of properties, including those under capital 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 which is measured in millions of gross tons per mile. 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.

In accordance with the group method of depreciation, upon sale or retirement of properties in the normal course of business, cost less net salvage value is charged to accumulated depreciation. As a result, no gain or loss is recognized in income under the group method as it is assumed that the assets within the group on average have the same life and characteristics and therefore that gains or losses offset over time. For retirements of depreciable properties that do not occur in the normal course of business, a gain or loss may be recognized if the retirement 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.

Assets held for sale are measured at the lower of their carrying amount or fair value, less cost to sell. Losses resulting from significant rail line sales are recognized in income when the asset meets the criteria for classification as held for sale, whereas losses resulting from significant rail line abandonments are recognized in the Consolidated Statement of Income when the asset ceases to be used. Gains are recognized in income when they are realized.

The Company reviews the carrying amounts of properties held and used whenever events or changes in circumstances indicate that such carrying amounts may not be recoverable based on future undiscounted cash flows. Assets that are deemed impaired as a result of such review are recorded at the lower of carrying amount or fair value.

Intangible assets

I. Intangible assets

Intangible assets consist mainly of customer contracts and relationships assumed through past acquisitions and are being amortized on astraight-line basis over 40 to 50 years.

The Company reviews the carrying amounts of intangible assets held and used whenever events or changes in circumstances indicate that such carrying amounts may not be recoverable based on future undiscounted cash flows. Assets that are deemed impaired as a result of such review are recorded at the lower of carrying amount or fair value.

Pensions

J. Pensions

Pension costs are determined using actuarial methods. Net periodic benefit cost is charged to income and includes:

(i)       the cost of pension benefits provided in exchange for employees' services rendered during the year;

(ii)       the interest cost of pension obligations;

(iii)the expected long-term return on pension fund assets;

(iv)       the amortization of prior service costs and amendments over the expected average remaining service life of the employee group covered by the plans; and

(v)       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

K. 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.

Personal injury and other claims

L. Personal injury and other claims

In Canada, the Company accounts for costs related to employee work-related injuries based on actuarially developed estimates 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.

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

M. Environmental expenditures

Environmental expenditures that relate to current operations, or to an existing condition caused by past operations, are expensed unless they can contribute to current or future operations. 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 and collectability is reasonably assured.

Income taxes policy

N. 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.

Derivative financial instruments

O. 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 and the changes in fair value are recorded in Net income or Other comprehensive income (loss) depending on the nature and effectiveness of the hedge transaction. Income and expense related to hedged derivative financial instruments are recorded in the same category as that generated by the underlying asset or liability.

Stock-based compensation

P. Stock-based compensation

The Company follows the fair value based approach for stock option awards based on the grant-date fair value using the Black-Scholes option-pricing model. The Company expenses the fair value of its stock option awards on a straight-line basis, over the period during which an employee is required to provide service (requisite service period) or until retirement eligibility is attained, whichever is shorter. The Company also follows the fair value based approach for cash settled awards using a lattice-based valuation model. Compensation cost for cash settled awards is based on the fair value of the awards at period-end and is recognized over the period during which an employee is required to provide service (requisite service period) or until retirement eligibility is attained, whichever is shorter. See Note 10 - Stockplans, for the assumptions used to determine fair value and for other required disclosures.
