Nature of Operations	'
	Canadian Pacific Railway Limited (“CPRL”), through its subsidiaries (collectively referred to as “CP” or “the Company”), operates a transcontinental railway in Canada and the United States. CP provides rail and intermodal transportation services over a network of approximately 14,400 miles, serving the principal business centres of Canada from Montreal, Quebec, to Vancouver, British Columbia, and the U.S. Northeast and Midwest regions. CP’s railway network feeds directly into the U.S. heartland from the East and West coasts. Agreements with other carriers extend the Company’s market reach east of Montreal in Canada, throughout the U.S. and into Mexico. CP transports bulk commodities, merchandise freight and intermodal traffic. Bulk commodities include grain, coal, fertilizers and sulphur. Merchandise freight consists of finished vehicles and automotive parts, as well as forest and industrial and consumer products. Intermodal traffic consists largely of retail goods in overseas containers that can be transported by train, ship and truck, and in domestic containers and trailers that can be moved by train and truck.

Summary of significant accounting policies	'
	1    Summary of significant accounting policies
	Generally accepted accounting principles in the United States of America (“GAAP”)
	These consolidated financial statements are expressed in Canadian dollars and have been prepared in accordance with GAAP as codified in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification.
	Principles of consolidation
	These consolidated financial statements include the accounts of CP and all its subsidiaries. The Company’s investments in which it has significant influence are accounted for using the equity method. All intercompany accounts and transactions have been eliminated.
	Use of estimates
	The preparation of these consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of revenues and expenses during the year, the reported amounts of assets and liabilities, and the disclosure of contingent assets and liabilities at the date of the financial statements. Management regularly reviews its estimates, including those related to investments, restructuring and environmental liabilities, pensions and other benefits, depreciable lives of properties and intangible assets, goodwill, stock-based compensation, deferred income tax assets and liabilities, as well as legal and personal injury liabilities based upon currently available information. Actual results could differ from these estimates.
	Principal subsidiaries
	The following list sets out CPRL’s principal railway operating subsidiaries, including the jurisdiction of incorporation. All of these subsidiaries are wholly owned, directly or indirectly, by CPRL as at December 31, 2013.
	Principal subsidiary	Incorporated under
		the laws of
	Canadian Pacific Railway Company	Canada
	Soo Line Railroad Company (“Soo Line”)	Minnesota
	Delaware and Hudson Railway Company, Inc. (“D&H”)	Delaware
	Dakota, Minnesota & Eastern Railroad Corporation (“DM&E”)	Delaware
	Mount Stephen Properties Inc. (“MSP”)	Canada
	Revenue recognition
	Railway freight revenues are recognized based on the percentage of completed service method. The allocation of revenue between reporting periods is based on the relative transit time in each reporting period with expenses recognized as incurred. Volume rebates to customers are accrued as a reduction of freight revenues based on estimated volume and contract terms as freight service is provided. Other revenues, including passenger revenue, revenue from leasing certain assets and switching fees, are recognized as service is performed or contractual obligations are met. Revenues are presented net of taxes collected from customers and remitted to government authorities.
	Cash and cash equivalents
	Cash and cash equivalents include highly-liquid short-term investments that are readily convertible to cash with original maturities of three months or less, but exclude cash and cash equivalents pledged as collateral or subject to other restrictions.
	Restricted cash and cash equivalents
	Restricted cash and cash equivalents include a series of committed and uncommitted bilateral letter of credit facility agreements with financial institutions to support the Company’s requirement to post letters of credit in the ordinary course of business. Under these agreements, the Company has the option to post collateral in the form of cash or cash equivalents, equal at least to the face value of the letter of credit issued. Restricted cash and cash equivalents are shown separately on the balance sheets and include highly liquid investments purchased three months or less from maturity and are stated at cost, which approximates market value.
	Foreign currency translation
	Assets and liabilities denominated in foreign currencies, other than those held through foreign subsidiaries, are translated into Canadian dollars at the year-end exchange rate for monetary items and at the historical exchange rates for non-monetary items. Foreign currency revenues and expenses are translated at the exchange rates in effect on the dates of the related transactions. Foreign exchange gains and losses, other than those arising from the translation of the Company’s net investment in foreign subsidiaries, are included in income.
	The accounts of the Company’s foreign subsidiaries are translated into Canadian dollars using the year-end exchange rate for assets and liabilities and the average exchange rates during the year for revenues, expenses, gains and losses. Foreign exchange gains and losses arising from translation of these foreign subsidiaries’ accounts are included in “Other comprehensive income (loss)”. The majority of U.S. dollar-denominated long-term debt has been designated as a hedge of the net investment in foreign subsidiaries. As a result, unrealized foreign exchange (“FX”) gains and losses on this U.S. dollar-denominated long-term debt are offset against foreign exchange gains and losses arising from translation of foreign subsidiaries’ accounts in “Other comprehensive income (loss)”.
	Pensions and other benefits
	Pension costs are actuarially determined using the projected-benefit method prorated over the credited service periods of employees. This method incorporates management’s best estimates of expected plan investment performance, salary escalation and retirement ages of employees. The expected return on fund assets is calculated using market-related asset values developed from a five-year average of market values for the fund’s public equity and absolute return investments (with each prior year’s market value adjusted to the current date for assumed investment income during the intervening period) plus the market value of the fund’s fixed income, real estate and infrastructure securities, subject to the market-related asset value not being greater than 120% of the market value nor being less than 80% of the market value. The discount rate used to determine the projected benefit obligation is based on blended market interest rates on high-quality corporate debt instruments with matching cash flows. Unrecognized actuarial gains and losses in excess of 10% of the greater of the benefit obligation and the market-related value of plan assets are amortized over the expected average remaining service period of active employees expected to receive benefits under the plan (approximately 10 years). Prior service costs arising from collectively bargained amendments to pension plan benefit provisions are amortized over the term of the applicable union agreement. Prior service costs arising from all other sources are amortized over the expected average remaining service period of active employees who are expected to receive benefits under the plan at the date of amendment.
	Costs for post-retirement and post-employment benefits other than pensions, including post-retirement health care and life insurance and some workers’ compensation and long-term disability benefits in Canada, are actuarially determined on a basis similar to pension costs.
	The over or under funded status of defined benefit pension and other post-retirement benefit plans are recognized on the balance sheet. The over or under funded status is measured as the difference between the fair value of the plan assets and the benefit obligation. In addition, any unrecognized actuarial gains and losses and prior service costs and credits that arise during the period are recognized as a component of “Other comprehensive income (loss)”, net of tax.
	Gains and losses on post-employment benefits that do not vest or accumulate, including some workers’ compensation and long-term disability benefits in Canada, are included immediately in income as “Compensation and benefits”.
	Materials and supplies
	Materials and supplies are carried at the lower of average cost or market.
	Properties
	Fixed asset additions and major renewals are recorded at cost, including direct costs, attributable indirect costs and carrying costs, less accumulated depreciation and any impairments. When there is a legal obligation associated with the retirement of property, a liability is initially recognized at its fair value and a corresponding asset retirement cost is added to the gross book value of the related asset and amortized to expense over the estimated term to retirement. The Company reviews the carrying amounts of its properties whenever changes in circumstances indicate that such carrying amounts may not be recoverable based on future undiscounted cash flows. When such properties are determined to be impaired, recorded asset values are revised to fair value.
	The Company recognizes expenditures as additions to properties or operating expenses based on whether the expenditures increase the output or service capacity, lower the associated operating costs or extend the useful life of the properties and whether the expenditures exceed minimum physical and financial thresholds.
	Much of the additions to properties, both new and replacement properties, are self-constructed. These are initially recorded at cost, including direct costs and attributable indirect costs, overheads and carrying costs. Direct costs include, among other things, labour costs, purchased services, equipment costs and material costs. Attributable indirect costs and overheads include incremental long-term variable costs resulting from the execution of capital projects. Indirect costs include largely local crew facilities, highway vehicles, work trains and area management costs. Overheads primarily include a portion of the cost of the Company’s engineering department which plans, designs and administers these capital projects. These costs are allocated to projects by applying a measure consistent with the nature of the cost based on cost studies. For replacement properties, the project costs are allocated to dismantling and installation based on cost studies. Dismantling work is performed concurrently with the installation.
	Ballast programs including undercutting, shoulder ballasting and renewal programs which form part of the annual track program are capitalized as this work, and the related added ballast material, significantly improves drainage which in turn extends the life of ties and other track materials. These costs are tracked separately from the underlying assets and depreciated over the period to the next estimated similar ballast program. Spot replacement of ballast is considered a repair which is expensed as incurred.
	The costs of large refurbishments are capitalized and locomotive overhauls are expensed as incurred.
	The Company capitalizes development costs for major new computer systems.
	The Company follows group depreciation which groups assets which are similar in nature and have similar economic lives. The property groups are depreciated based on their expected economic lives determined by studies of historical retirements of properties in the group and engineering estimates of changes in current operations and of technological advances. Actual use and retirement of assets may vary from current estimates, which would impact the amount of depreciation expense recognized in future periods.
	When depreciable property is retired or otherwise disposed of in the normal course of business, the book value, less net salvage proceeds, is charged to accumulated depreciation and if different than the assumptions under the depreciation study could potentially result in adjusted depreciation expense over a period of years. However, when removal costs exceed the salvage value on assets and the Company has no legal obligation to remove the assets, the removal costs incurred are charged to income in the period in which the assets are removed and are not charged to accumulated depreciation.
	For the sale or retirement of larger groups of depreciable assets that are unusual and were not considered in depreciation studies, CP records a gain or loss for the difference between net proceeds and net book value of the assets sold or retired.
	Depreciation is calculated on the straight-line basis at rates based on the estimated service life, taking into consideration the projected annual usage of depreciable property, except for rail and other track material in the U.S., which is based directly on usage.
	Equipment under capital lease is included in Properties and depreciated over the period of expected use.
	Assets held for sale
	Assets to be disposed that meet the held for sale criteria are reported at the lower of their carrying amount and fair value, less costs to sell, and are no longer depreciated.
	Goodwill and intangible assets
	Goodwill represents the excess of the purchase price over the fair value of identifiable net assets upon acquisition of a business. Goodwill is assigned to the reporting units that are expected to benefit from the business acquisition which, after integration of operations with the railway network, may be different than the acquired business.
	The carrying value of goodwill, which is not amortized, is assessed for impairment annually in the fourth quarter of each year, or more frequently as economic events dictate. The fair value of the reporting unit is compared to its carrying value, including goodwill. If the fair value of the reporting unit is less than its carrying value goodwill is potentially impaired. The impairment charge that would be recognized is the excess of the carrying value of the goodwill over the fair value of the goodwill, determined in the same manner as in a business combination.
	Intangible assets with finite lives are amortized on a straight-line basis over the estimated useful lives of the respective assets. Favourable leases, customer relationships and interline contracts have amortization periods ranging from 15 to 20 years. When there is a change in the estimated useful life of an intangible asset with a finite life, amortization is adjusted prospectively.
	Financial instruments
	Financial instruments are contracts that give rise to a financial asset of one party and a financial liability or equity instrument of another party.
	Financial instruments are recognized initially at fair value, which is the amount of consideration that would be agreed upon in an arm’s length transaction between willing parties.
	Subsequent measurement depends on how the financial instruments have been classified. Accounts receivable and investments, classified as loans and receivables, are measured at amortized cost, using the effective interest method. Certain equity investments, classified as available for sale, are recognized at cost as fair value cannot be reliably established. Cash and cash equivalents are classified as held for trading and are measured at fair value. Accounts payable, accrued liabilities, short-term borrowings, dividends payable, other long-term liabilities and long-term debt, classified as other liabilities, are also measured at amortized cost.
	Derivative financial instruments
	Derivative financial and commodity instruments may be used from time to time by the Company to manage its exposure to risks relating to foreign currency exchange rates, stock-based compensation, interest rates and fuel prices. When CP utilizes derivative instruments in hedging relationships, CP identifies, designates and documents those hedging transactions and regularly tests the transactions to demonstrate effectiveness in order to continue hedge accounting.
	All derivative instruments are classified as held for trading and recorded at fair value. Any change in the fair value of derivatives not designated as hedges is recognized in the period in which the change occurs in the Consolidated Statements of Income in the line item to which the derivative instrument is related. On the Consolidated Balance Sheets they are classified in “Other assets”, “Other long-term liabilities”, “Other current assets” or “Accounts payable and accrued liabilities” as applicable. Gains and losses arising from derivative instruments affect the following income statement lines: “Revenues”, “Compensation and benefits”, “Fuel”, “Other income and charges”, and “Net interest expense”.
	For fair value hedges, the periodic changes in values are recognized in income, on the same line as the changes in values of the hedged items are also recorded. For a cash flow hedge, the change in value of the effective portion is recognized in “Other comprehensive income”. Any ineffectiveness within an effective cash flow hedge is recognized in income as it arises in the same income account as the hedged item. Should a cash flow hedging relationship become ineffective, previously unrealized gains and losses remain within “Accumulated other comprehensive loss” until the hedged item is settled and, prospectively, future changes in value of the derivative are recognized in income. The change in value of the effective portion of a cash flow hedge remains in “Accumulated other comprehensive loss” until the related hedged item settles, at which time amounts recognized in “Accumulated other comprehensive loss” are reclassified to the same income or balance sheet account that records the hedged item.
	In the Consolidated Statements of Cash Flows, cash flows relating to derivative instruments designated as hedges are included in the same line as the related hedged items.
	The Company from time to time enters into foreign exchange forward contracts to hedge anticipated sales in U.S. dollars, the related accounts receivable and future capital acquisitions. Foreign exchange translation gains and losses on foreign currency-denominated derivative financial instruments used to hedge anticipated U.S. dollar-denominated sales are recognized as an adjustment of the revenues when the sale is recorded. Those used to hedge future capital acquisitions are recognized as an adjustment of the property amount when the acquisition is recorded.
	The Company also occasionally enters into foreign exchange forward contracts as part of its short-term cash management strategy. These contracts are not designated as hedges due to their short-term nature and are carried on the Consolidated Balance Sheets at fair value. Changes in fair value are recognized in income in the period in which the changes occur.
	The Company enters into interest rate swaps to manage the risk related to interest rate fluctuations. These swap agreements require the periodic exchange of payments without the exchange of the principal amount on which the payments are based. Interest expense on the debt is adjusted to include the payments owing or receivable under the interest rate swaps.
	The Company from time to time enters into bond forwards to fix interest rates for anticipated issuances of debt. These agreements are usually accounted for as cash flow hedges with gains and losses recorded in “Accumulated other comprehensive loss” and amortized to “Net interest expense” in the period that interest on the related debt is charged.
The Company entered into derivatives called Total Return Swaps (“TRS”) to mitigate fluctuations in tandem share appreciation rights (“TSAR”), deferred share units (“DSU”) and restricted share units (“RSU”). These were not designated as hedges and were recorded at market value with the offsetting gain or loss reflected in “Compensation and benefits”.
Restructuring accrual
Restructuring liabilities are recorded at their present value. The discount related to liabilities is amortized to “Compensation and benefits” over the payment period. Provisions for labour restructuring are recorded in “Other long-term liabilities”, except for the current portion, which is recorded in “Accounts payable and accrued liabilities”.
Environmental remediation
Environmental remediation accruals, recorded on an undiscounted basis, cover site-specific remediation programs. Provisions for environmental remediation costs are recorded in “Other long-term liabilities”, except for the current portion, which is recorded in “Accounts payable and accrued liabilities”.
Income taxes
The Company follows the liability method of accounting for income taxes. Deferred income tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect of a change in income tax rates on deferred income tax assets and liabilities is recognized in income in the period during which the change occurs.
When appropriate, the Company records a valuation allowance against deferred tax assets to reflect that these tax assets may not be realized. In determining whether a valuation allowance is appropriate, CP considers whether it is more likely than not that all or some portion of CP’s deferred tax assets will not be realized, based on management’s judgment using available evidence about future events.
At times, tax benefit claims may be challenged by a tax authority. Tax benefits are recognized only for tax positions that are more likely than not sustainable upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in CP’s tax returns that do not meet these recognition and measurement standards.
Investment and other similar tax credits are deferred on the Consolidated Balance Sheets and amortized to “Income tax expense” as the related asset is recognized in income.
Earnings per share
Basic earnings per share are calculated using the weighted average number of Common Shares outstanding during the year. Diluted earnings per share are calculated using the treasury stock method for determining the dilutive effect of options.
Stock-based compensation
CP follows the fair value based approach to account for stock options. Compensation expense and an increase in additional paid-in capital are recognized for stock options over their vesting period, or over the period from the grant date to the date employees become eligible to retire when this is shorter than the vesting period, based on their estimated fair values on the grant date, as determined using the Black-Scholes option-pricing model.
With the granting of regular stock options, some employees have been simultaneously granted share appreciation rights, which provide the employee the choice to either exercise the stock option for shares, or to exercise the TSAR and thereby receive the intrinsic value of the stock option in cash. Options with TSARs are awards that may call for settlement in cash and, therefore, are recorded as liabilities. CP follows the fair value based approach, as determined by the Black-Scholes option pricing model, to account for the TSAR liability. The liability is fair valued and changes in the liability are recorded in “Compensation and benefits” over the vesting period, or over the period from the grant date to the date employees become eligible to retire when this is shorter than the vesting period, until exercised. If an employee chooses to exercise the option, thereby cancelling the TSAR, both the exercise price and the liability are settled to “Share capital”.
Forfeitures of options and tandem options are estimated at issuance and subsequently at the balance sheet date.
Any consideration paid by employees on exercise of stock options is credited to share capital when the option is exercised and the recorded fair value of the option is removed from additional paid-in capital and credited to share capital.
Compensation expense is also recognized for TSARs, DSUs, performance share units (“PSUs”) and RSUs using the fair value method. Forfeitures of TSARs, DSUs, PSUs and RSUs are estimated at issuance and subsequently at the balance sheet date.
The employee share purchase plan (“ESPP”) gives rise to compensation expense that is recognized using the issue price by amortizing the cost over the vesting period or over the period from the grant date to the date employees become eligible to retire when this is shorter than the vesting period.

	Accumulated other comprehensive income
	In February 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, an amendment to FASB ASC Topic 220. The update requires disclosure of amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present either on the face of the income statement or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For amounts not reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2012. The disclosure requirements of this ASU for the year ended December 31, 2013 are presented in Note 9.

	(a) Dakota, Minnesota & Eastern Railroad – West
	On January 2, 2014, the Company executed an agreement with Genesee & Wyoming Inc. (“G&W”) for the sale of a portion of CP’s DM&E line between Tracy, Minnesota and Rapid City, South Dakota, Colony, Wyoming and Crawford, Nebraska and connecting branch lines (“DM&E West”). The sale, which is subject to regulatory approval by the U.S. Surface Transportation Board, is expected to generate approximately US$215 million in gross proceeds, subject to closing adjustments, and is expected to close in 2014.
	At December 31, 2013, CP has classified DM&E West as an asset held for sale carried at CDN$222 million, being its estimated fair value less estimated direct selling costs. As a result, in the fourth quarter of 2013, the Company recorded an asset impairment charge and accruals for future costs associated with the sale totaling CDN$435 million ($257 million after-tax). The components of the asset impairment charge and charge for the accruals, which are subject to closing adjustments, that were recorded against income as “Asset impairments” are as follows:
	(in millions of Canadian dollars)	2013
	Property, plant and equipment	$	426
	Intangible assets		2
	Goodwill		6
	Total asset impairment charge		434
	Accruals for future costs		1
	Total charge	$	435
	(b) Powder River Basin impairment
	As part of the acquisition of DM&E in 2007, CP acquired the option to build a 260 mile extension of its network into coal mines in the Powder River Basin (“PRB”).
	Due to continued deterioration in the market for domestic thermal coal, including a sharp deterioration in 2012, in the fourth quarter of 2012 CP deferred plans to extend its rail network into the PRB coal mines indefinitely. As a result of this decision and in light of the declined market conditions, CP has evaluated the recoverability of the carrying amount of PRB assets and determined that this exceeded the estimated fair value by $180 million. The estimated fair value represents the expected proceeds from the sale of the acquired land, as determined by a comparable market assessment. Other costs associated with the acquisition of DM&E and accumulated by CP since acquisition have been written down to $nil. The amount of the impairment associated with this indefinite deferral was $180 million ($107 million after-tax). The components of the PRB impairment that were charged against income as “Asset impairments” in 2012 are as follows:
	(in millions of Canadian dollars)	2012
	Option impairment (Note 15)	$	26
	Construction plans, including capitalized interest		134
	Land, land option appraisals, including capitalized interest		20
	Total impairment	$	180
	(c) Impairment loss on locomotives
	In the fourth quarter of 2012, CP reached a decision to dispose of a certain series of locomotives to improve operating efficiencies, and accordingly performed an impairment test on these assets. The impairment test determined that the net book value of these locomotives exceeded their estimated fair value by $80 million. The estimated fair value represents the expected future cashflows from the disposal of these locomotives. The impairment charge of $80 million ($59 million after tax) was recorded in “Asset impairments” and charged against income.

	In 2013, CP recorded a recovery of $7 million ($5 million after tax) (2012 – a charge of $53 million, $39 million after tax) for a labour restructuring initiative which was included in “Labour restructuring” in the Consolidated Statements of Income, and “Accounts payable and accrued liabilities” and “Other long-term liabilities” in the Consolidated Balance Sheets. The resulting position reductions are expected to be completed by the end of 2014, with the majority achieved in 2013.
	At December 31, 2013, the provision for restructuring was $50 million (2012 – $89 million). The restructuring accrual was primarily for labour liabilities arising for restructuring plans, including those from prior year initiatives. Payments are expected to continue in diminishing amounts until 2025.
	Set out below is a reconciliation of CP’s liabilities associated with its restructuring accrual:

	(1) Current income tax recovery in 2011 includes a reduction to the Company’s uncertain tax positions.
	The provision for deferred income taxes arises from temporary differences in the carrying values of assets and liabilities for financial statement and income tax purposes and the effect of loss carry forwards. The items comprising the deferred income tax assets and liabilities are as follows:
	(in millions of Canadian dollars)	2013			2012
	Deferred income tax assets

	Long-term deferred income tax liabilities	$	2,903		$	2,092
	The Company’s consolidated effective income tax rate differs from the expected statutory tax rates. Expected income tax expense at statutory rates is reconciled to income tax expense as follows:

	Income tax expense	$	250		$	152		$	127
	(1) Substantially all amounts relate to uncertain tax positions.
	The Company has no unrecognized tax benefits from capital losses at December 31, 2013 and 2012.
	The Company has not provided a deferred liability for the income taxes, if any, which might become payable on any temporary difference associated with its foreign investments because the Company intends to indefinitely reinvest in its foreign investments and has no intention to realize this difference by a sale of its interest in foreign investments.
	During the third quarter of 2013, legislation was enacted to increase the province of British Columbia’s corporate income tax rate. As a result, the Company recalculated its deferred income taxes as at January 1, 2013 based on this change and recorded an income tax expense of $7 million in the third quarter of 2013.
	During the second quarter of 2012, legislation was enacted to cancel the previously planned province of Ontario’s corporate income tax rate reductions. As a result of these changes, the Company recorded an income tax expense of $11 million in the second quarter of 2012, based on its deferred income tax balances as at December 31, 2011.
At December 31, 2013, the Company had income tax operating losses carried forward of $339 million, which have been recognized as a deferred tax asset. Certain of these losses carried forward will begin to expire in 2015, with the majority expiring between 2029 and 2031. The Company also has minimum tax credits of approximately $47 million that will begin to expire in 2016 as well as investment tax credits of $40 million, certain of which will begin to expire in 2018, and track maintenance credits of $16 million which will begin to expire in 2032.
It is more likely than not that the Company will realize the majority of its deferred income tax assets from the generation of future taxable income, as the payments for provisions, reserves and accruals are made and losses and tax credits carried forward are utilized.
The following table provides a reconciliation of uncertain tax positions in relation to unrecognized tax benefits for Canada and the United States for the year ended December 31, 2013:
(in millions of Canadian dollars)	2013			2012			2011
Unrecognized tax benefits at January 1	$	19		$	19		$	60
Increase in unrecognized:
Tax benefits related to the current year		4			2			3
Gross uncertain tax benefits related to prior years		–			–			1
Dispositions:
Gross uncertain tax benefits related to prior years		(7	)		(2	)		(45	)
Unrecognized tax benefits at December 31	$	16		$	19		$	19
If these uncertain tax positions were recognized, all of the amount of unrecognized tax positions as at December 31, 2013 would impact the Company’s effective tax rate.
The Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense in the Company’s Consolidated Statement of Income. The total amount of accrued interest and penalties in 2013 was a credit of $1 million (2012 – $nil; 2011 – credit of $15 million). The total amount of accrued interest and penalties associated with the unrecognized tax benefit at December 31, 2013 was $4 million (2012 – $5 million; 2011 – $5 million).
The Company and its subsidiaries are subject to either Canadian federal and provincial income tax, U.S. federal, state and local income tax, or the relevant income tax in other international jurisdictions. The Company has substantially concluded all Canadian federal and provincial income tax matters for the years through 2009. The federal and provincial income tax returns filed for 2010 and subsequent years remain subject to examination by the taxation authorities.
All U.S. federal income tax returns and generally all U.S. state and local income tax returns are closed to 2006. The income tax returns for 2007 and subsequent years continue to remain subject to examination by the taxation authorities.
The Company does not anticipate any material changes to the unrecognized tax benefits previously disclosed within the next twelve months as at December 31, 2013.

Earnings per share	'
	8    Earnings per share
	Basic earnings per share have been calculated using net income for the year divided by the weighted average number of shares outstanding during the year.
	Diluted earnings per share have been calculated using the treasury stock method, which assumes that any proceeds received from the exercise of in-the-money options would be used to purchase Common Shares at the average market price for the period. For purposes of this calculation, at December 31, 2013, there were 3.2 million dilutive options outstanding (2012 – 4.2 million; 2011 – 4.7 million). These option totals at December 31, 2013 exclude no options (2012 – 0.2 million; 2011 – 0.3 million) for which there are TSARs outstanding (Note 24), as these are not included in the dilution calculation.
	The number of shares used in the earnings per share calculations is reconciled as follows:
	(in millions)	2013		2012		2011
	Weighted average shares outstanding		174.9		171.8		169.5
	Dilutive effect of weighted average number of stock options		1.6		1.4		1.1
	Weighted average diluted shares outstanding		176.5		173.2		170.6
	In 2013, the number of options excluded from the computation of diluted earnings per share, because their effect was not dilutive, was nil (2012 – 0.2 million; 2011 – 1.4 million).

	As part of the acquisition of DM&E in 2007, CP recognized goodwill of US$147 million on the allocation of the purchase price, determined as the excess of the purchase price over the fair value of the net assets acquired. Since the acquisition, the operations of DM&E have been integrated with CP’s U.S. operations and the related goodwill is allocated to CP’s U.S. reporting unit. Goodwill is tested for impairment at least once per year as at October 1st. The goodwill impairment test determines if the fair value of the reporting unit continues to exceed its net book value, or whether an impairment charge is required. The fair value of the reporting unit is affected by projections of its profitability including estimates of revenue growth, which are inherently uncertain.
	Intangible assets of $12 million (2012 – $15 million), acquired in the acquisition of DM&E, includes favourable leases, customer relationships and interline contracts.
	At December 31, 2013, CP has classified DM&E West as an asset held for sale, which resulted in a goodwill impairment charge of $6 million and an intangible assets impairment charge of $2 million (Note 3).
	Due to continued deterioration in the market for domestic thermal coal, including a sharp deterioration in 2012, in the fourth quarter of 2012 CP deferred plans to extend its rail network into the PRB coal mines indefinitely. The amount of the impairment associated with the option to expand the track network, previously included in intangible assets, was $26 million (Note 3).
	The estimated amortization expense for intangible assets for 2014 to 2018 is insignificant each year.

	At December 31, 2013, the gross amount of long-term debt denominated in U.S. dollars was US$3,527 million (2012 – US$3,538 million).
	Annual maturities and principal repayments requirements, excluding those pertaining to capital leases, for each of the five years following 2013 are (in millions): 2014 – $50; 2015 – $127; 2016 – $31; 2017 – $28; 2018 – $697.
	A.  These debentures and notes pay interest semi-annually and are unsecured, but carry a negative pledge.
	On September 30, 2011, the Company redeemed US$101 million 5.75% Notes due in May 2013 with a carrying amount of $107 million pursuant to a call offer for a total cost of $113 million. Upon redemption of the Notes a net loss of $9 million was recognized to “Other income and charges”. The loss consisted largely of a redemption premium paid to note holders to redeem the Notes.
	On September 13, 2011, the Company announced a cash tender offer and consent solicitation for any or all its outstanding US$246 million 6.25% Notes due October 15, 2011. Notes tendered with a principal value of US$204 million were redeemed on October 12, 2011, and the remaining US$42 million Notes not tendered were redeemed on October 17, 2011. Upon redemption of the Notes a net loss of $1 million was recognized to “Other income and charges”.
	During December 2011, the Company issued $125 million 5.10% 10-year Medium Term Notes, US$250 million 4.50% 10-year Notes and US$250 million 5.75% 30-year Notes. Net proceeds from these offerings were $618 million and were largely used to make a $600 million voluntary prepayment to the Company’s main Canadian defined benefit pension plan.
	B.  The Secured Equipment Loan is collateralized by specific locomotive units with a carrying value of $65 million at December 31, 2013. The floating interest rate is calculated based on a six-month average Canadian Dollar Offered Rate (calculated based on an average of Bankers’ Acceptance rates) plus 53 basis points (2013 – 1.93%; 2012 – 1.97%; 2011 – 1.94%). The Company makes blended payments of principal and interest semi-annually. Final repayment of the remaining principal balance of $53 million is due in August 2015.
	C.  The 5.41% Senior Secured Notes are collateralized by specific locomotive units with a carrying value of $141 million at December 31, 2013. The Company pays equal blended semi-annual payments of principal and interest. Final repayment of the remaining principal of US$44 million is due in March 2024.
	D.  The 6.91% Secured Equipment Notes are full recourse obligations of the Company collateralized by a first charge on specific locomotive units with a carrying value of $139 million at December 31, 2013. The Company pays equal blended semi-annual payments of principal and interest up to and including October 2024.
	E.  The 5.57% Senior Secured Notes are secured by specific locomotive units and other rolling stock with a combined carrying value of $59 million at December 31, 2013. The Company pays equal blended semi-annual payments of principal and interest up to and including December 2024. Final repayment of the remaining principal of US$33 million is due in December 2024.
	F.  The 7.49% Equipment Trust Certificates are secured by specific locomotive units with a carrying value of $104 million at December 31, 2013. The Company makes semi-annual payments that vary in amount and are interest-only payments or blended principal and interest payments. Final repayment of the remaining principal of US$11 million is due in January 2021.
	G.  During 2011, the Company issued US$139 million 3.88% Series A and B Senior Secured Notes due in 2026 for net proceeds of $139 million. These Notes are secured by locomotives previously acquired by the Company with a carrying value of $131 million at December 31, 2013. The Company pays equal blended semi-annual payments of principal and interest up to and including December 2026. Final repayment of the remaining principal of US$69 million is due in the fourth quarter of 2026.
	H.  During 2012, the Company issued US$71 million 4.28% Senior Secured Notes due in 2027 for net proceeds of $71 million. These Notes are secured by locomotives previously acquired by the Company with a carrying value of $68 million at December 31, 2013. The Company pays equal blended semi-annual payments of principal and interest up to and including March 2027. Final repayment of the remaining principal of US$35 million is due in March 2027.
	I. At December 31, 2013, capital lease obligations included in long-term debt were as follows:
	(in millions of Canadian dollars)	Year				Capital leases
	Minimum lease payments in:
			2014			$	160

	Long-term portion of capital lease obligations					$	141
	During the year the Company had no additions to property, plant and equipment under capital lease obligations (2012 – $nil; 2011 – $nil).
	The carrying value of the assets collateralizing the capital lease obligations was $316 million at December 31, 2013.
J.  The Consolidated Debenture Stock, authorized by an Act of Parliament of 1889, constitutes a first charge upon and over the whole of the undertaking, railways, works, rolling stock, plant, property and effects of the Company, with certain exceptions.
K.  During November 2013, CP extended its revolving credit agreement, dated October 31, 2011, by three years to November 29, 2018. The amended agreement is with 13 highly rated financial institutions for a committed amount of $1.165 billion and also contains an uncommitted accordion feature to a maximum size of $1.5 billion. The agreement can accommodate draws of cash and/or letters of credit at pre-agreed pricing. At December 31, 2013, the facility was undrawn. The weighted average annualized interest rate of the facility for drawn funds was not applicable in 2013 compared to 2.94% in 2012 and 1.98% in 2011. The agreement requires the Company not to exceed a maximum debt to total capitalization ratio. At December 31, 2013, the Company satisfied this threshold stipulated in the financial covenant. In addition, should CP’s senior unsecured debt not be rated at least investment grade by Moody’s and S&P, the Company’s credit agreement will also require it to maintain a minimum fixed charge coverage ratio.
L.  During 2013, the Company entered into a series of committed and uncommitted bilateral letter of credit facility agreements with financial institutions to support its requirement to post letters of credit in the ordinary course of business. The agreements have varying expiration dates with the earliest expiry in August 2014. Under these agreements, the Company has the option to post collateral in the form of cash or cash equivalents, equal at least to the face value of the letter of credit issued. Collateral provided includes highly liquid investments purchased three months or less from maturity and is stated at cost, which approximates market value and is shown separately on the balance sheet as “Restricted cash and cash equivalents”.
At December 31, 2013, under its bilateral facilities the Company had letters of credit drawn of $394 million from a total available amount of $585 million. Prior to these bilateral agreements, letters of credit were drawn under the Company’s revolving credit facility. At December 31, 2013, cash and cash equivalents of $411 million were pledged as collateral and recorded as “Restricted cash and cash equivalents”, $nil in 2012. The Company can withdraw this collateral during any month.

Financial Instruments	12 Months Ended
	Dec. 31, 2013
Financial Instruments	'
	19    Financial Instruments
	A.  Fair values of financial instruments
	The Company categorizes its financial assets and liabilities measured at fair value in line with the fair value hierarchy established by GAAP that prioritizes, with respect to reliability, the inputs to valuation techniques used to measure fair value. This hierarchy consists of three broad levels. Level 1 inputs consist of quoted prices (unadjusted) in active markets for identical assets and liabilities and give the highest priority to these inputs. Level 2 and 3 inputs are based on significant other observable inputs and significant unobservable inputs, respectively, and give lower priority to these inputs.
	When possible, the estimated fair value is based on quoted market prices and, if not available, estimates from third party brokers. For non-exchange traded derivatives classified in Level 2, the Company uses standard valuation techniques to calculate fair value. Primary inputs to these techniques include observable market prices (interest, foreign exchange and commodity) and volatility, depending on the type of derivative and nature of the underlying risk. The Company uses inputs and data used by willing market participants when valuing derivatives and considers its own credit default swap spread as well as those of its counterparties in its determination of fair value.
	The carrying values of financial instruments equal or approximate their fair values with the exception of long-term debt which has a fair value of approximately $5,572 million at December 31, 2013 (December 31, 2012 – $5,688 million) with a carrying value of $4,876 million (December 31, 2012 – $4,690 million). The estimated fair value of current and long-term borrowings has been determined based on market information where available, or by discounting future payments of interest and principal at estimated interest rates expected to be available to the Company at period end. All derivatives and long-term debt are classified as Level 2.
	B.  Fair values of non-financial assets
	At December 31, 2013, CP classified DM&E West as an asset held for sale carried at its estimated fair value less estimated direct selling costs (Note 3). During 2012, CP reviewed certain properties, goodwill, and certain related intangible assets for impairment (Note 3) and estimated the fair values of those properties. These estimated fair values were based on measurements classified as Level 3 which resulted in the recording of total impairment charges in 2013 of $434 million and in 2012 of $265 million (Note 3). CP used third party information that was corroborated with other internal information to estimate the fair value of these properties.
	The techniques used to value long-term floating rate notes, which were classified as Level 3, is discussed below:
	Long-term floating rate notes
	At December 31, 2013 and December 31, 2012, the Company had no remaining investment in long-term floating rate notes.
	During 2012, the Company sold its remaining investment in long-term floating rate notes (Master Asset Vehicle (“MAV”) 2 Class A-1 and A-2 Notes) which had a carrying value of $81 million (original cost – $105 million) for proceeds of $81 million.
	Accretion, redemption of notes and other minor changes in market assumptions resulted in a net gain of $2 million in 2012 (2011 – $15 million), which was reported in “Other income and charges”.
	The valuation technique and assumptions used by the Company to estimate the fair value of its investment in long-term floating rate notes during 2012 and 2011 incorporated probability weighted discounted cash flows considered the best available public information regarding market conditions and other factors that a market participant would have considered for such investments.
	C.  Financial risk management
	Derivative financial instruments
	Derivative financial instruments may be used to selectively reduce volatility associated with fluctuations in interest rates, foreign exchange (“FX”) rates, the price of fuel and stock-based compensation expense. Where derivatives are designated as hedging instruments, the relationship between the hedging instruments and their associated hedged items is documented, as well as the risk management objective and strategy for the use of the hedging instruments. This documentation includes linking the derivatives that are designated as fair value or cash flow hedges to specific assets or liabilities on the Consolidated Balance Sheets, commitments or forecasted transactions. At the time a derivative contract is entered into, and at least quarterly thereafter, an assessment is made whether the derivative item is effective in offsetting the changes in fair value or cash flows of the hedged items. The derivative qualifies for hedge accounting treatment if it is effective in substantially mitigating the risk it was designed to address.
	It is not the Company’s intent to use financial derivatives or commodity instruments for trading or speculative purposes.
	Credit risk management
	Credit risk refers to the possibility that a customer or counterparty will fail to fulfil its obligations under a contract and as a result create a financial loss for the Company.
	The railway industry predominantly serves financially established customers and the Company has experienced limited financial losses with respect to credit risk. The credit worthiness of customers is assessed using credit scores supplied by a third party, and through direct monitoring of their financial well-being on a continual basis. The Company establishes guidelines for customer credit limits and should thresholds in these areas be reached, appropriate precautions are taken to improve collectability.
	Counterparties to financial instruments expose the Company to credit losses in the event of non-performance. Counterparties for derivative and cash transactions are limited to high credit quality financial institutions, which are monitored on an on-going basis. Counterparty credit assessments are based on the financial health of the institutions and their credit ratings from external agencies. The Company does not anticipate non-performance that would materially impact the Company’s financial statements. In addition, the Company believes there are no significant concentrations of credit risk.
	Foreign exchange management
	The Company conducts business transactions and owns assets in both Canada and the United States. As a result, the Company is exposed to fluctuations in value of financial commitments, assets, liabilities, income or cash flows due to changes in FX rates. The Company may enter into foreign exchange risk management transactions primarily to manage fluctuations in the exchange rate between Canadian and U.S. currencies. FX exposure is primarily mitigated through natural offsets created by revenues, expenditures and balance sheet positions incurred in the same currency. Where appropriate, the Company may negotiate with customers and suppliers to reduce the net exposure.
	Occasionally the Company will enter into short-term FX forward contracts as part of its cash management strategy.
	Net investment hedge
	The FX gains and losses on long-term debt are mainly unrealized and can only be realized when U.S. dollar denominated long-term debt matures or is settled. The Company also has long-term FX exposure on its investment in U.S. affiliates. The majority of the Company’s U.S. dollar denominated long-term debt has been designated as a hedge of the net investment in foreign subsidiaries. This designation has the effect of mitigating volatility on net income by offsetting long-term FX gains and losses on U.S. dollar denominated long-term debt and gains and losses on its net investment. The effective portion recognized in “Other comprehensive income (loss)” in 2013 was an unrealized foreign exchange loss of $217 million (2012 – unrealized gain of $69 million; 2011 – unrealized loss of $59 million) (Note 9). There was no ineffectiveness during 2013 (2012 – $nil; 2011 – $nil).
	Foreign exchange forward contracts
	The Company may enter into FX forward contracts to lock-in the amount of Canadian dollars it has to pay on U.S. denominated debt maturities.
	At December 31, 2013, the Company had FX forward contracts to fix the exchange rate on US$100 million of principal outstanding on a capital lease due in January 2014, US$175 million of its 6.50% Notes due in May 2018, and US$100 million of its 7.25% Notes due in May 2019, unchanged from December 31, 2012. These derivatives, which are accounted for as cash flow hedges, guarantee the amount of Canadian dollars that the Company will repay when these obligations mature.
	During 2013, an unrealized foreign exchange gain of $18 million (2012 – unrealized loss of $4 million; 2011 – realized and unrealized gain of $8 million) was recorded in “Other income and charges” in relation to these derivatives. Gains recorded in “Other income and charges” were largely offset by unrealized losses on the underlying debt which the derivatives were designated to hedge. Similarly, losses were largely offset by unrealized gains on the underlying debt.
	At December 31, 2013, the unrealized gain derived from these FX forwards was $25 million (2012 – $8 million) of which $6 million (2012 – $nil) was included in “Other current assets” and $19 million (2012 – $8 million) in “Other assets” with the offset reflected as an unrealized gain of $5 million (2012 – $6 million) in “Accumulated other comprehensive loss” and as an unrealized gain of $20 million (2012 – $2 million) in “Retained earnings”.
	During 2011, in anticipation of a cash tender to offer to redeem the Company’s US$101 million 5.75% May 2013 Notes, the Company unwound a similar amount of FX forward contracts to fix the exchange rate on these Notes for total proceeds of $2 million (Note 18).
	At December 31, 2013, the Company expected that, during the next twelve months, unrealized pre-tax losses of $1 million would be reclassified to “Other income and charges”.
	Interest rate management
	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. In order to manage funding needs or capital structure goals, the Company enters into debt or capital lease agreements that are subject to either fixed market interest rates set at the time of issue or floating rates determined by on-going market conditions. Debt subject to variable interest rates exposes the Company to variability in interest expense, while debt subject to fixed interest rates exposes the Company to variability in the fair value of debt.
	To manage interest rate exposure, the Company accesses diverse sources of financing and manages borrowings in line with a targeted range of capital structure, debt ratings, liquidity needs, maturity schedule, and currency and interest rate profiles. In anticipation of future debt issuances, the Company may enter into forward rate agreements such as treasury rate locks, bond forwards or forward starting swaps, designated as cash flow hedges, to substantially lock in all or a portion of the effective future interest expense. The Company may also enter into swap agreements, designated as fair value hedges, to manage the mix of fixed and floating rate debt.
	Interest rate swaps
	At December 31, 2013 and December 31, 2012, the Company had no outstanding interest rate swaps, nor did it enter into or unwind any such transactions during 2013.
	During 2011, the Company amortized $5 million of deferred gains to “Net interest expense” relating to interest rate swaps previously unwound in 2010 and 2009. In addition, during 2011, the Company amortized $2 million of deferred gains to “Other income and charges” as a result of the redemption of 5.75% May 2013 Notes (Note 18). These gains were deferred as a fair value adjustment to the underlying debts that were hedged and were amortized to “Net interest expense” until the debts were redeemed in 2011.
	Treasury rate locks
	At December 31, 2013, the Company had net unamortized losses related to interest rate locks, which are accounted for as cash flow hedges, settled in previous years totalling $22 million (December 31, 2012 – $22 million). This amount is composed of various unamortized gains and losses related to specific debts which are reflected in “Accumulated other comprehensive loss” and are amortized to “Net interest expense” in the period that interest on the related debt is charged. The amortization of these gains and losses resulted in a negligible increase to “Net interest expense” and “Other comprehensive income (loss)” in 2013 (2012 – negligible; 2011 – negligible).
	At December 31, 2013, the Company expected that, during the next twelve months, a negligible amount of loss related to these previously settled derivatives would be reclassified to “Net interest expense”.
	Fuel price management
	The Company is exposed to commodity risk related to purchases of diesel fuel and the potential reduction in net income due to increases in the price of diesel. Fuel expense constitutes a large portion of the Company’s operating costs and volatility in diesel fuel prices can have a significant impact on the Company’s income. Items affecting volatility in diesel prices include, but are not limited to, fluctuations in world markets for crude oil and distillate fuels, which can be affected by supply disruptions and geopolitical events.
	The impact of variable fuel expense is mitigated substantially through fuel cost recovery programs which apportion incremental changes in fuel prices to shippers through price indices, tariffs, and by contract, within agreed upon guidelines. While these programs provide effective and meaningful coverage, residual exposure remains as the fuel expense risk may not be completely recovered from shippers due to timing and volatility in the market. In the past, to address the residual portion of CP’s fuel costs not mitigated by its fuel cost recovery programs, CP had a systematic hedge program. As a result of improving coverage from its fuel cost recovery programs, CP exited its hedging program during the first quarter of 2013.
	Energy futures
	During the first quarter ended March 31, 2013, the Company settled its remaining diesel futures contracts, accounted for as cash flow hedges, to purchase 20 million U.S. gallons during 2013 for proceeds of $2 million.
	During the twelve months ended December 31, 2013, the impact of settled swaps decreased “Fuel” expense by $2 million, as a result of realized gains on diesel swaps (2012 – realized gains $1 million; 2011 – realized gains $8 million).
	At December 31, 2013, the Company had no outstanding diesel futures contracts. At December 31, 2012, the unrealized loss on these contracts was negligible.
	Stock-based compensation expense management
	Total return swaps (“TRS”)
	The Company is exposed to stock-based compensation risk, which is the probability of increased compensation expense when the Company’s share price rises.
	The TRS was a derivative that provided a gain to offset increased compensation expense as the share price increased and a loss to offset reduced compensation expense when the share price declined. If stock-based compensation share units fall out of the money after entering the program, the loss associated with the swap would no longer be fully offset by the compensation expense reductions, which would reduce the effectiveness of the swap. This derivative was not designated as a hedge and changes in fair value were recognized in net income in the period in which the change occurred.
	At December 31, 2013 and December 31, 2012, the Company had no share units remaining in the TRS.
	During 2012, the Company exited the TRS program and unwound 0.6 million of its remaining share units for proceeds of $3 million. During the same period of 2011, the program was reduced by 0.5 million share units at minimal cost.
	“Compensation and benefits” expense on the Company’s Consolidated Statements of Income included a net gain on these swaps of $6 million in 2012 (2011 – $3 million). There was no impact to “Compensation and benefits” expense in 2013.

	The deferred revenue on rights-of-way license agreements, and deferred gains on sale leaseback transactions are being amortized to income on a straight-line basis over the related lease terms. Deferred income credits are being amortized over the life of the related asset.
	Environmental remediation accruals
	Environmental remediation accruals cover site-specific remediation programs. Environmental remediation accruals are measured on an undiscounted basis and are recorded when the costs to remediate are probable and reasonably estimable. The estimate of the probable costs to be incurred in the remediation of properties contaminated by past railway use reflects the nature of contamination at individual sites according to typical activities and scale of operations conducted. CP has developed remediation strategies for each property based on the nature and extent of the contamination, as well as the location of the property and surrounding areas that may be adversely affected by the presence of contaminants, considering available technologies, treatment and disposal facilities and the acceptability of site-specific plans based on the local regulatory environment. Site-specific plans range from containment and risk management of the contaminants through to the removal and treatment of the contaminants and affected soils and ground water. The details of the estimates reflect the environmental liability at each property. Provisions for environmental remediation costs are recorded in “Other long-term liabilities”, except for the current portion which is recorded in “Accounts payable and accrued liabilities”. Payments are expected to be made over ten years to 2023.
	The accruals for environmental remediation represent CP’s best estimate of its probable future obligation and include both asserted and unasserted claims, without reduction for anticipated recoveries from third parties. Although the recorded accruals include CP’s best estimate of all probable costs, CP’s total environmental remediation costs cannot be predicted with certainty. Accruals for environmental remediation may change from time to time as new information about previously untested sites becomes known, environmental laws and regulations evolve and advances are made in environmental remediation technology. The accruals may also vary as the courts decide legal proceedings against outside parties responsible for contamination. These potential charges, which cannot be quantified at this time, may materially affect income in the particular period in which a charge is recognized. Costs related to existing, but as yet unknown, or future contamination will be accrued in the period in which they become probable and reasonably estimable. Changes to costs are reflected as changes to “Other long-term liabilities” or “Accounts payable and accrued liabilities” on the Consolidated Balance Sheets and to “Purchased services and other” within operating expenses on the Consolidated Statements of Income. The amount charged to income in 2013 was $6 million (2012 – $4 million; 2011 – $3 million).

Pensions_and_other_benefits

Pensions and other benefits	'
	23    Pensions and other benefits
	The Company has both defined benefit (“DB”) and defined contribution (“DC”) pension plans. At December 31, 2013, the Canadian pension plans represent approximately 99% of total combined pension plan assets and approximately 98% of total combined pension plan obligations.
	The DB plans provide for pensions based principally on years of service and compensation rates near retirement. Pensions for Canadian pensioners are partially indexed to inflation. Annual employer contributions to the DB plans, which are actuarially determined, are made on the basis of being not less than the minimum amounts required by federal pension supervisory authorities.
	CP reached agreements with all of the unions which it had been bargaining with in Canada in 2012. The new agreements introduced amendments to pension plans. Among other changes, the amendments established a cap on pension for each year of pensionable service, including a cap on some non-union employees’ pensions. Under the amendments, plan participants will continue to earn additional pensionable years of service as before, but with a dollar limit on the pension amount for each year earned. Plan amendments resulting from collective bargaining are accounted for in the periods the new agreements are ratified. The plan amendments resulting from the December 2012 arbitration award were contingent on CP making plan amendments for non-union employees, and consequently were accounted for in the period CP made such amendments. As a result of the plan amendments, the projected benefit obligation decreased by $135 million from December 31, 2012, with a corresponding increase to “Other comprehensive income” and a reduction of “Accumulated other comprehensive loss” as prior service credits. The prior service credits are recognized in net periodic pension expense over the remaining terms of the applicable union agreements (averaging approximately two years), and over the expected average remaining service life of non-union employees.
	The Company has other benefit plans including post-retirement health and life insurance for pensioners, and post-employment long-term disability and workers’ compensation benefits, which are based on Company-specific claims. At December 31, 2013, the Canadian other benefits plans represent approximately 96% of total combined other plan obligations.
	The Finance Committee of the Board of Directors has approved an investment policy that establishes long-term asset mix targets which take into account the Company’s expected risk tolerances. Pension plan assets are managed by a suite of independent investment managers, with the allocation by manager reflecting these asset mix targets. Most of the assets are actively managed with the objective of outperforming applicable benchmarks. In accordance with the investment policy, derivative instruments may be used to hedge or adjust existing or anticipated exposures. At December 31, 2013, derivatives were primarily being used to partially hedge foreign currency exposures.
	To develop the expected long-term rate of return assumption used in the calculation of net periodic benefit cost applicable to the market-related value of assets, the Company considers the expected composition of the plans’ assets, past experience and future estimates of long-term investment returns. Future estimates of investment returns reflect the expected annual yield on applicable fixed income capital market indices, and the long-term return expectation for public equity, real estate, infrastructure and absolute return investments and the expected added value (relative to applicable benchmark indices) from active management of pension fund assets.
	The Company has elected to use a market-related value of assets for the purpose of calculating net periodic benefit cost, developed from a five-year average of market values for the plans’ public equity and absolute return investments (with each prior year’s market value adjusted to the current date for assumed investment income during the intervening period) plus the market value of the plans’ fixed income, real estate and infrastructure securities.
	The benefit obligation is discounted using a discount rate that is a blended interest rate for a portfolio of high-quality corporate debt instruments with matching cash flows. The discount rate is determined by management with the aid of third-party actuaries.
	The elements of net periodic benefit cost for DB pension plans and other benefits recognized in the year included the following components:

	The defined benefit pension plans’ accumulated benefit obligation as at December 31, 2013 was $9,578 million (2012 – $10,122 million). The accumulated benefit obligation is calculated on a basis similar to the projected benefit obligation, except no future salary increases are assumed in the projection of future benefits.
	The measurement date used to determine the plan assets and the accrued benefit obligation is December 31. The most recent actuarial valuation for pension funding purposes for the Company’s main Canadian pension plan was performed as at January 1, 2013. During 2014, the Company expects to file a new valuation with the pension regulator.

Plan assets
Plan assets are recorded at fair value. The major asset categories are public equity securities, debt securities, and real estate, infrastructure and absolute return investments. The fair values of the public equity and debt securities are primarily based on quoted market prices. Real estate values are based on annual valuations performed by external parties, taking into account current market conditions and recent sales transactions where practical and appropriate. Infrastructure values are based on the fair value of each fund’s assets as calculated by the fund manager, generally using a discounted cash flow analysis that takes into account current market conditions and recent sales transactions where practical and appropriate. Absolute return investments are a portfolio of units of externally managed hedge funds, which are valued by the fund administrators.
The Company’s pension plan asset allocation, the current weighted average asset allocation targets and the current weighted average policy range for each major asset class, were as follows:

(1) Government & Corporate Bonds:
Fair values for bonds are based on market prices supplied by independent pricing sources as of the last trading day.
Mortgages: The fair value measurement of $52 million (2012 – $34 million) of mortgages categorized as Level 2 is based on current market yields of financial instruments of similar maturity, coupon and risk factors.
(2) Real Estate:
The fair value of real estate investments of $847 million (2012 – $779 million) is based on property appraisals which use a number of approaches that typically include a discounted cash flow analysis, a direct capitalization income method and/or a direct comparison approach. Appraisals of real estate investments are generally performed semi-annually by qualified external accredited appraisers. There are no unfunded commitments for real estate as at December 31, 2013.
Infrastructure:
Infrastructure fund values of $314 million (2012 – $333 million) are based on the fair value of the fund assets as calculated by the fund manager, generally using a discounted cash flow analysis that takes into account current market conditions and recent sales transactions where practical and appropriate. As at December 31, 2013, unfunded commitments for the infrastructure funds were $23 million (2012 – $24 million).
(3) Absolute Return:
The fair value of absolute return investments is based on the net asset value reported by the fund administrators. The funds have different redemption policies and periods. All hedge fund investments have contractual redemption frequencies, ranging from monthly to tri-annually, and redemption notice periods varying from 30 to 95 days. Hedge fund investments that have redemption dates less frequent than every four months or have restrictions on contractual redemption features at the reporting date are classified as Level 3. There are no unfunded commitments for absolute return fund investments as at December 31, 2013.
¨	Funds of hedge funds invest in a portfolio of hedge funds that allocate capital across a broad array of funds and/or investment managers.
¨	Multi-strategy funds include funds that invest in broadly diversified portfolios of equity, fixed income and derivative instruments.
¨	Credit funds invest in an array of fixed income securities.
¨	Equity funds invest primarily in U.S. and global equity securities.
(4) At December 31, 2013, derivatives were primarily being used to partially hedge foreign currency exposures. The Company’s pension funds may utilize the following derivative instruments: equity futures to replicate equity index returns (Level 2); currency forwards to partially hedge foreign currency exposures (Level 2); bond forwards to reduce asset/liability interest rate risk exposures (Level 2); interest rate swaps to manage duration and interest rate risk (Level 2); credit default swaps to manage credit risk (Level 2); and options to manage interest rate risk and volatility (Level 2).
During 2012 and 2013, the portion of the assets of the Company’s DB pension plans measured at fair value using unobservable inputs (Level 3) changed as follows:
(in millions of Canadian dollars)	Mortgages			Real Estate			Infrastructure				Absolute Return				Total

Level 3 fair value measurements for absolute return, real estate and infrastructure investments are based on the net asset value reported by the fund administrator, property appraisals and discounted cash flow analysis, of which there are no reasonable alternative assumptions. Therefore it is not practicable to provide a sensitivity analysis.
The Company’s expected long-term target return is 7.75%, net of all fees and expenses. In identifying the asset allocation ranges, consideration was given to the long-term nature of the underlying plan liabilities, the solvency and going-concern financial position of the plan, long-term return expectations and the risks associated with key asset classes as well as the relationships of returns on key asset classes with each other, inflation and interest rates. When advantageous and with due consideration, derivative instruments may be utilized, provided the total value of the underlying assets represented by financial derivatives, excluding currency forwards, is limited to 30% of the market value of the fund.
When investing in foreign securities, the plans are exposed to foreign currency risk; the effect of which is included in the valuation of the foreign securities. Net of the above hedging, the plans were 24% exposed to the U.S. dollar, 5% exposed to European currencies, and 5% exposed to various other currencies, as at December 31, 2013.
At December 31, 2013, fund assets consisted primarily of listed stocks and bonds, including 129,444 of the Company’s Common Shares (2012 – $nil) at a market value of $21 million (2012 – $nil) and 6.25% Unsecured Notes issued by the Company at a par value of $2 million (2012 – $2 million) and a market value of $2 million (2012 – $2 million). At December 31, 2012, the fund assets also held 6.91% Secured Equipment Notes issued by the Company at a par value of $2 million and a market value of $3 million.
Cash flows
In 2013, the Company contributed $105 million to its pension plans (2012 – $107 million; 2011 – $698 million), including $7 million to the DC plans (2012 – $5 million; 2011 – $5 million), $86 million to the Canadian registered and U.S. qualified DB pension plans (2012 – $89 million; 2011 – $696 million), and $12 million to the Canadian non-registered supplemental pension plan (2012 – $13 million contribution; 2011 – $3 million net refund). Contributions to the main Canadian registered DB plan included voluntary prepayments of $600 million in 2011. In addition, the Company made payments directly to employees, their beneficiaries or estates or to third-party benefit administrators of $32 million in 2013 (2012 – $35 million; 2011 – $35 million) with respect to other benefits.
Estimated future benefit payments
The estimated future defined benefit pension and other benefit payments to be paid by the plans for each of the next five years and the subsequent five-year period are as follows:
(in millions of Canadian dollars)	Pensions			Other benefits
2014	$	535		$	37
2015		554			37
2016		572			37
2017		590			37
2018		607			36
2019 – 2023		3,216			175
The benefit payments from the Canadian registered and U.S. qualified DB pension plans are payable from their respective pension funds. Benefit payments from the supplemental pension plan and from the other benefits plans are payable directly from the Company.
Defined contribution plan
Canadian non-unionized employees hired prior to July 1, 2010 had the option to participate in the Canadian DC plan. All Canadian non-unionized employees hired after such date must participate in this plan. Employee contributions are based on a percentage of salary. The Company matches employee contributions to a maximum percentage each year.
Effective July 1, 2010, a new U.S. DC plan was established. All U.S. non-unionized employees hired after such date must participate in this plan. Employees do not contribute to the plan. The Company annually contributes a percentage of salary.
The DC plans provide a pension based on total employee and employer contributions plus investment income earned on those contributions.
In 2013, the net cost of the DC plans, which generally equals the employer’s required contribution, was $7 million (2012 – $5 million; 2011 – $5 million).
Contributions to multi-employer plans
Some of the Company’s unionized employees in the U.S. are members of a U.S. national multi-employer benefit plan. Contributions made by the Company to this plan in 2013 in respect of post-retirement medical benefits were $5 million (2012 – $6 million; 2011 – $6 million).

Stockbased_compensation

Stock-based compensation	12 Months Ended
	Dec. 31, 2013
Stock-based compensation	'
	24    Stock-based compensation
	At December 31, 2013, the Company had several stock-based compensation plans, including stock option plans, various cash settled liability plans and an employee stock savings plan. These plans resulted in an expense in 2013 of $92 million (2012 – $64 million; 2011 – $43 million).
	Accelerated vesting due to changes in the composition of the Board of Directors
	Most of the stock-based compensation plans include a provision whereby vesting is accelerated should certain changes in the composition of the Board of Directors occur. These provisions were triggered on June 26, 2012 and the recognition of the revised vesting terms as outlined in the stock-based compensation plans resulted in a credit to “Compensation and benefits” of $8 million in the second quarter of 2012. From February 28, 2012, accelerated vesting will only occur when the definition of change of control under the stock-based compensation plans is triggered and the holder of the award is terminated without cause.
	A. Stock Option Plans
	Regular options and TSARs
	With the granting of regular options, employees may be simultaneously granted TSARs equivalent to the number of regular options granted (stock options granted prior to January 2009 were simultaneously granted TSARs equivalent to one-half the regular options granted). The last issue of TSARs was in April 2010. A TSAR entitles the holder to receive payment of an amount equal to the excess of the market value of a Common Share at the exercise date of the TSAR over the related option exercise price. The liability for TSARs is recognized and measured at its fair value. Pursuant to the employee plans, regular options and TSARs vest between 12 and 48 months after the grant date, and will expire after 10 years. Certain of these options granted are only exercisable after employment is terminated.
	Where an option granted is a tandem award, the holder can choose to exercise an option or a TSAR of equal intrinsic value.
	As a result of changes to Canadian tax legislation, which eliminated the favourable tax treatment on cash settled compensation awards, the Company offered employees the option of cancelling the outstanding SAR and keeping in place the outstanding option. During 2011, the Company cancelled 3.5 million SARs and reclassified the fair value of the previously recognized liability ($75 million) and the recognized deferred tax asset ($18 million) to “Additional paid-in capital”. The terms of the awards were not changes and as a result no incremental cost was recognized. The weighted-average fair value of the units cancelled was $23.75.

	(1) As at December 31, 2013, the total number of in-the-money stock options outstanding was 3,360,483 with a weighted-average exercise price of $77.15. The weighted-average years to expiration of exercisable stock options is 4.7 years.
	Under the fair value method, the fair value of options at the grant date was approximately $20 million for options issued in 2013 (2012 – $28 million; 2011 – $12 million). The weighted-average fair value assumptions were approximately:
		2013			2012			2011

	(1) Represents the period of time that awards are expected to be outstanding. Historical data on exercise behaviour or, when available, specific expectations regarding future exercise behaviour were used to estimate the expected life of the option.
	(2) Based on the implied yield available on zero-coupon government issues with an equivalent remaining term at the time of the grant.
	(3) Based on the historical stock price volatility of the Company’s stock over a period commensurate with the expected term of the option.
	(4) Determined by the current annual dividend at the time of grant. The Company does not employ different dividend yields throughout the contractual term of the option.
	(5) The Company estimated forfeitures based on past experience. The rate is monitored on a periodic basis.
	Certain of the Company’s stock option plans are subject to post-vesting restrictions prior to expiry. The discount for these restrictions resulted in a reduction of the fair value at grant date of options issued in 2012 of $2 million. This discount was estimated using the fair value of put options that, together with the granted call options, mimicked the characteristics of the post-vesting restriction. The post-vesting restrictions do not relate to grants in 2013.
	In 2013, the expense for stock options (regular and performance) was $17 million (2012 –$24 million; 2011 –$15 million). At December 31, 2013, there was $17 million of total unrecognized compensation related to stock options which is expected to be recognized over a weighted-average period of approximately 2.2 years.
	At December 31, 2013, there were 2,426,425 (2012 – 2,728,685; 2011 – 3,459,831) Common Shares available for the granting of future options under the stock option plans, out of the 18,966,842 (2012 – 18,728,642; 2011 – 15,578,642) Common Shares currently authorized for issuance.

B. Other Share-based Plans
Performance share unit (“PSU”) plan
During 2013, the Company issued 206,405 PSUs. These units attract dividend equivalents in the form of additional units based on the dividends paid on the Company’s Common Shares. PSUs vest and are settled in cash, or in CP common shares approximately three years after the grant date, contingent upon CP’s performance (performance factor). The fair value of PSUs is measured, both on the grant date and each subsequent quarter until settlement, using a Monte Carlo simulation model. The model utilizes multiple input variables that determine the probability of satisfying the performance and market conditions stipulated in the grant.
In the second quarter of 2012, changes to the Board resulted in the immediate vesting of a pro-rata portion of all unvested PSUs. The number of units that vested was based on the number of months of the total performance period that had passed and the fair value of the units to be settled was based on the average closing price of the 30 trading days prior to June 26, 2012. The payout of $31 million occurred in the third quarter of 2012.
The performance period for the PSUs issued in the fourth quarter of 2012 and in 2013 is January 1, 2013 to December 31, 2015. The performance factors for these PSUs are Operating ratio, Free cash flow, Total Shareholder Return (“TSR”) compared to the S&P/TSX60 index, and TSR compared to Class I railways.
The performance period for the first grant of PSUs issued in 2009 ended December 31, 2011. These PSUs were earned based on TSR compared to the S&P/TSX60 index, and Return on Capital Employed (“ROCE”). The TSR for the three-year period exceeded target, while ROCE targets were not met. The TSR component of the plan resulted in a total PSU payout equal to 200% for half of the award, in effect resulting in a target payout. The payout of $24 million occurred in March 2012 and was calculated using the Company’s average share price during the last 30 trading days ending on December 31, 2011.
The following table summarizes information related to the Company’s PSUs as at December 31:
	2013			2012
Outstanding, January 1		200,702			930,311
Granted		206,405			479,372
Units, in lieu of dividends		3,498			2,143
Vested		–			(610,568	)
Forfeited		(60,680	)		(600,556	)
Outstanding at December 31		349,925			200,702
Under the fair value method, the fair value of PSUs at the grant date was $26 million for PSUs issued in 2013 (2012 – $38 million; 2011 – $16 million).
In 2013, the expense for PSUs was $25 million (2012 – expense recovery of $1 million; 2011 – expense of $15 million). At December 31, 2013, there was $58 million of total unrecognized compensation related to PSUs which is expected to be recognized over a weighted-average period of approximately 2.0 years.
Deferred share unit plan
The Company established the DSU plan as a means to compensate and assist in attaining share ownership targets set for certain key employees and Directors. A DSU entitles the holder to receive, upon redemption, a cash payment equivalent to the market value of a Common Share at the redemption date. DSUs vest over various periods of up to 48 months and are only redeemable for a specified period after employment is terminated.
Senior Managers may elect to receive DSUs in lieu of cash payments for certain incentive programs. In addition, when acquiring common shares to meet ownership targets, Senior Managers were granted with a 25% company match of the amount elected. Beginning in 2013, the 25% company match now only applies to DSUs granted. The election to receive eligible payments in DSUs is no longer available to a participant when the value of the participant’s DSUs is sufficient to meet the Company’s stock ownership guidelines. Senior Managers have five years to meet their ownership targets.
An expense to income for DSUs is recognized over the vesting period for both the initial subscription price and the change in value between reporting periods.
The following table summarizes information related to the DSUs as of December 31:
	2013			2012
Outstanding, January 1		357,740			396,306
Granted		76,035			167,435

Redeemed		(103,327	)		(212,822	)
Outstanding, December 31		332,221			357,740
During 2013, the Company granted 76,035 DSUs with a grant date fair value of $10 million. In 2013, the expense for DSUs was $32 million (2012 – expense of $23 million; 2011 – expense of $5 million). At December 31, 2013, there was $6 million of total unrecognized compensation related to DSUs which is expected to be recognized over a weighted-average period of approximately 1.2 years.
Restricted share unit plan
The Company did not issue RSUs in 2013 (2012 – 113,408; 2011 – 64,470). The RSUs are notional full value shares that attract dividend equivalents in the form of additional units based on the dividends paid on the Company’s Common Shares. RSUs have no performance factors attached to them and are subject to time vesting over various periods of up to 36 months. RSUs are settled in cash up to three years after the grant date. An expense to income for RSUs is recognized over the vesting period for both the initial subscription price and the change in value between reporting periods. In 2013, the expense for RSUs was $10 million (2012 – $7 million; 2011 – $nil). At December 31, 2013, there was $5 million of total unrecognized compensation related to RSUs which is expected to be recognized over a weighted-average period of approximately 1.0 years.
The following table summarizes information related to the Company’s RSUs as at December 31:

C. Employee share purchase plan
The Company has an employee share purchase plan whereby both employee and Company contributions are used to purchase shares on the open market for employees. The Company’s contributions are expensed over the one-year vesting period. Under the plan, the Company matches $1 for every $3 contributed by employees up to a maximum employee contribution of 6% of annual salary.
The total number of shares purchased in 2013 on behalf of participants, including the Company contribution, was 271,934 (2012 – 445,951; 2011 – 630,480). In 2013, the Company’s contributions totalled $5 million (2012 – $4 million; 2011 – $4 million) and the related expense was $5 million (2012 – $4 million; 2011 – $4 million).

Variable interest entities	'
	25    Variable interest entities
	The Company leases equipment from certain trusts, which have been determined to be variable interest entities financed by a combination of debt and equity provided by unrelated third parties. The lease agreements, which are classified as operating leases, have a fixed price purchase option which create the Company’s variable interest and result in the trusts being considered variable interest entities.
	Responsibility for maintaining and operating the leased assets according to specific contractual obligations outlined in the terms of the lease agreements and industry standards is the Company’s. The rigor of the contractual terms of the lease agreements and industry standards are such that the Company has limited discretion over the maintenance activities associated with these assets. As such, the Company concluded these terms do not provide the Company with the power to direct the activities of the variable interest entities in a way that has a significant impact on the entities’ economic performance.
	The financial exposure to the Company as a result of its involvement with the variable interest entities is equal to the fixed lease payments due to the trusts. In 2013, lease payments after tax were $9 million. Future minimum lease payments, before tax, of $207 million will be payable over the next 17 years.
	The Company does not guarantee the residual value of the assets to the lessor, however, it must deliver to the lessor the assets in good operating condition, subject to normal wear and tear, at the end of the lease term.
	As the Company’s actions and decisions do not significantly affect the variable interest entities’ performance, and the Company’s fixed price purchase option is not considered to be potentially significant to the variable interest entities, the Company is not considered to be the primary beneficiary, and does not consolidate these variable interest entities.

	In the normal course of its operations, the Company becomes involved in various legal actions, including claims relating to injuries and damage to property. The Company maintains provisions it considers to be adequate for such actions. While the final outcome with respect to actions outstanding or pending at December 31, 2013, cannot be predicted with certainty, it is the opinion of management that their resolution will not have a material adverse effect on the Company’s financial position or results of operations.
	On July 6, 2013, a train carrying crude oil operated by Montreal Maine and Atlantic Railway (“MM&A”) derailed and exploded in Lac-Megantic, Quebec on a section of railway line owned by MM&A. The day before CP had interchanged the train to MM&A, but after the interchange MM&A exercised exclusive control over the train.
	Following this incident, the Minister of Sustainable Development, Environment, Wildlife and Parks of Quebec issued an order directing named parties to recover the contaminants and to clean up and decontaminate the derailment site. CP was later added as a named party in the administrative action on August 14, 2013.
	A class action lawsuit has also been filed in the Superior Court of Quebec on behalf of a class of persons and entities residing in, owning or leasing property in, operating a business in or physically present in Lac-Megantic. The lawsuit seeks damages caused by the derailment including for wrongful deaths, personal injuries, and property damages. CP was added as a defendant on August 16, 2013. In the wake of the derailment and ensuing litigation, MM&A filed for bankruptcy in Canada and the United States. At this early stage in the legal proceedings, any potential liability and the quantum of potential loss cannot be determined. Nevertheless, CP denies liability for MM&A’s derailment and will vigorously defend itself in both proceedings or any proceeding that may be commenced in the future.
	At December 31, 2013, the Company had committed to total future capital expenditures amounting to $569 million and operating expenditures relating to supplier purchase obligations, such as locomotive maintenance and overhaul agreements, as well as agreements to purchase other goods and services amounting to approximately $1.5 billion for the years 2014-2046, of which CP estimates approximately $0.8 billion will be incurred within the next 5 years.
	As at December 31, 2013, the Company’s commitments under operating leases were estimated at $684 million in aggregate, with minimum annual payments in each of the next five years and thereafter as follows:

	Expenses for operating leases for the year ended December 31, 2013 were $154 million (2012 – $182 million; 2011 – $161 million).
	During the three months ended March 31, 2013, CP provided an interest free loan pursuant to a court order in the amount of $20 million to a corporation owned by a court appointed trustee to facilitate the acquisition of a building. The building will be held in trust until the resolution of legal proceedings with regard to CP’s entitlement to an exercised purchase option of the building. If CP is successful in these proceedings, title to the building will transfer to CP with an additional payment of $20 million; otherwise the loan will be repaid.

	In the normal course of operating the railway, the Company enters into contractual arrangements that involve providing certain guarantees, which extend over the term of the contracts. These guarantees include, but are not limited to:
	¨	residual value guarantees on operating lease commitments of $159 million at December 31, 2013;
	¨	guarantees to pay other parties in the event of the occurrence of specified events, including damage to equipment, in relation to assets used in the operation of the railway through operating leases, rental agreements, easements, trackage and interline agreements; and
	¨	indemnifications of certain tax-related payments incurred by lessors and lenders.
	The maximum amount that could be payable under these guarantees, excluding residual value guarantees, cannot be reasonably estimated due to the nature of certain of these guarantees. All or a portion of amounts paid under guarantees to other parties in the event of the occurrence of specified events could be recoverable from other parties or through insurance. The Company has accrued for all guarantees that it expects to pay. At December 31, 2013, these accruals amounted to $6 million (2012 – $6 million), recorded in “Accounts payable and accrued liabilities”.
	Indemnifications
	Pursuant to a trust and custodial services agreement with the trustee of the Canadian Pacific Railway Company Pension Plan, the Company has undertaken to indemnify and save harmless the trustee, to the extent not paid by the fund, from any and all taxes, claims, liabilities, damages, costs and expenses arising out of the performance of the trustee’s obligations under the agreement, except as a result of misconduct by the trustee. The indemnity includes liabilities, costs or expenses relating to any legal reporting or notification obligations of the trustee with respect to the defined contribution option of the pension plans or otherwise with respect to the assets of the pension plans that are not part of the fund. The indemnity survives the termination or expiry of the agreement with respect to claims and liabilities arising prior to the termination or expiry. At December 31, 2013, the Company had not recorded a liability associated with this indemnification, as it does not expect to make any payments pertaining to it.

Management transition	'
	28    Management transition
	On May 17, 2012, following a proxy contest, Mr. Fred Green left his position as President and Chief Executive Officer of the Company. That same day, Mr. Stephen Tobias, a new Board member elected at the Company’s annual shareholders meeting held on May 17, 2012, was appointed by the Board as Interim Chief Executive Officer and served in that role until June 28, 2012.
	On June 28, 2012, Mr. E. Hunter Harrison was appointed by the Board as President and Chief Executive Officer. As a result of the appointment of Mr. Harrison, the Company recorded a charge of $38 million with respect to compensation and other transition costs, including $2 million of associated costs, in the second quarter of 2012. This charge was recorded in the Company’s financial statements in “Compensation and benefits” and “Purchased services and other”, in the amounts of $16 million and $22 million, respectively.
	Included in this charge were amounts totalling $16 million in respect of deferred retirement compensation for Mr. Harrison and $20 million to Pershing Square Capital Management, L.P. (“Pershing Square”) and related entities. In 2012, Pershing Square and related entities owned or controlled approximately 14% of the Company’s outstanding shares, and two Board members, Mr. William Ackman and Mr. Paul Hilal, are partners of Pershing Square. The amount payable to Pershing Square and related entities was to reimburse them, on behalf of Mr. Harrison, for certain amounts they had previously paid to or incurred on behalf of Mr. Harrison pursuant to an indemnity in favour of Mr. Harrison in connection with losses suffered in legal proceedings commenced against Mr. Harrison by his former employer. The terms of Pershing Square’s indemnity required Mr. Harrison to return any funds advanced under the indemnity in the event he accepted employment at CP. As a result, Mr. Harrison made it a precondition of accepting the Company’s offer of employment that CP assumes the indemnity obligations and return the funds advanced by Pershing Square. As a result of the payment, the Company would have been entitled to enforce Mr. Harrison’s rights in the aforementioned legal proceedings, allowing it to recover to the extent of Mr. Harrison’s success in those proceedings; however on February 3, 2013 the Company and Mr. Harrison settled the legal proceedings with Mr. Harrison’s former employer, providing the Company with partial recovery (US$9 million) of the amounts in the dispute. The Company may receive repayment in other circumstances in the event of certain breaches by Mr. Harrison of his obligations under an employment agreement with the Company. Mr. Harrison was also granted stock options and DSUs upon commencing employment that had a grant date fair value of $12 million (Note 24).
	In addition, the Company agreed to indemnify Mr. Harrison for certain other amounts, to a maximum of $3 million plus legal fees, but as a result of the settlement of the aforementioned legal proceedings, such indemnity is no longer applicable. Accordingly, no amount was accrued at December 31, 2012.
	The Company also recorded a charge of $4 million in the second quarter of 2012 with respect to a retirement allowance for Mr. Green.
	On February 5, 2013, as part of its long-term succession plan, the Company appointed Mr. Keith Creel as President and Chief Operating Officer. In connection with this appointment, Mr. Harrison’s title changed to Chief Executive Officer.

Revenue recognition	'
	Revenue recognition
	Railway freight revenues are recognized based on the percentage of completed service method. The allocation of revenue between reporting periods is based on the relative transit time in each reporting period with expenses recognized as incurred. Volume rebates to customers are accrued as a reduction of freight revenues based on estimated volume and contract terms as freight service is provided. Other revenues, including passenger revenue, revenue from leasing certain assets and switching fees, are recognized as service is performed or contractual obligations are met. Revenues are presented net of taxes collected from customers and remitted to government authorities.
Cash and cash equivalents	'
	Cash and cash equivalents
	Cash and cash equivalents include highly-liquid short-term investments that are readily convertible to cash with original maturities of three months or less, but exclude cash and cash equivalents pledged as collateral or subject to other restrictions.
Restricted cash and cash equivalents	'
	Restricted cash and cash equivalents
	Restricted cash and cash equivalents include a series of committed and uncommitted bilateral letter of credit facility agreements with financial institutions to support the Company’s requirement to post letters of credit in the ordinary course of business. Under these agreements, the Company has the option to post collateral in the form of cash or cash equivalents, equal at least to the face value of the letter of credit issued. Restricted cash and cash equivalents are shown separately on the balance sheets and include highly liquid investments purchased three months or less from maturity and are stated at cost, which approximates market value.
Foreign currency translation	'
	Foreign currency translation
	Assets and liabilities denominated in foreign currencies, other than those held through foreign subsidiaries, are translated into Canadian dollars at the year-end exchange rate for monetary items and at the historical exchange rates for non-monetary items. Foreign currency revenues and expenses are translated at the exchange rates in effect on the dates of the related transactions. Foreign exchange gains and losses, other than those arising from the translation of the Company’s net investment in foreign subsidiaries, are included in income.
	The accounts of the Company’s foreign subsidiaries are translated into Canadian dollars using the year-end exchange rate for assets and liabilities and the average exchange rates during the year for revenues, expenses, gains and losses. Foreign exchange gains and losses arising from translation of these foreign subsidiaries’ accounts are included in “Other comprehensive income (loss)”. The majority of U.S. dollar-denominated long-term debt has been designated as a hedge of the net investment in foreign subsidiaries. As a result, unrealized foreign exchange (“FX”) gains and losses on this U.S. dollar-denominated long-term debt are offset against foreign exchange gains and losses arising from translation of foreign subsidiaries’ accounts in “Other comprehensive income (loss)”.
Pensions and other benefits	'
	Pensions and other benefits
	Pension costs are actuarially determined using the projected-benefit method prorated over the credited service periods of employees. This method incorporates management’s best estimates of expected plan investment performance, salary escalation and retirement ages of employees. The expected return on fund assets is calculated using market-related asset values developed from a five-year average of market values for the fund’s public equity and absolute return investments (with each prior year’s market value adjusted to the current date for assumed investment income during the intervening period) plus the market value of the fund’s fixed income, real estate and infrastructure securities, subject to the market-related asset value not being greater than 120% of the market value nor being less than 80% of the market value. The discount rate used to determine the projected benefit obligation is based on blended market interest rates on high-quality corporate debt instruments with matching cash flows. Unrecognized actuarial gains and losses in excess of 10% of the greater of the benefit obligation and the market-related value of plan assets are amortized over the expected average remaining service period of active employees expected to receive benefits under the plan (approximately 10 years). Prior service costs arising from collectively bargained amendments to pension plan benefit provisions are amortized over the term of the applicable union agreement. Prior service costs arising from all other sources are amortized over the expected average remaining service period of active employees who are expected to receive benefits under the plan at the date of amendment.
	Costs for post-retirement and post-employment benefits other than pensions, including post-retirement health care and life insurance and some workers’ compensation and long-term disability benefits in Canada, are actuarially determined on a basis similar to pension costs.
	The over or under funded status of defined benefit pension and other post-retirement benefit plans are recognized on the balance sheet. The over or under funded status is measured as the difference between the fair value of the plan assets and the benefit obligation. In addition, any unrecognized actuarial gains and losses and prior service costs and credits that arise during the period are recognized as a component of “Other comprehensive income (loss)”, net of tax.
	Gains and losses on post-employment benefits that do not vest or accumulate, including some workers’ compensation and long-term disability benefits in Canada, are included immediately in income as “Compensation and benefits”.
Materials and supplies	'
	Materials and supplies
	Materials and supplies are carried at the lower of average cost or market.
Properties	'
	Properties
	Fixed asset additions and major renewals are recorded at cost, including direct costs, attributable indirect costs and carrying costs, less accumulated depreciation and any impairments. When there is a legal obligation associated with the retirement of property, a liability is initially recognized at its fair value and a corresponding asset retirement cost is added to the gross book value of the related asset and amortized to expense over the estimated term to retirement. The Company reviews the carrying amounts of its properties whenever changes in circumstances indicate that such carrying amounts may not be recoverable based on future undiscounted cash flows. When such properties are determined to be impaired, recorded asset values are revised to fair value.
	The Company recognizes expenditures as additions to properties or operating expenses based on whether the expenditures increase the output or service capacity, lower the associated operating costs or extend the useful life of the properties and whether the expenditures exceed minimum physical and financial thresholds.
	Much of the additions to properties, both new and replacement properties, are self-constructed. These are initially recorded at cost, including direct costs and attributable indirect costs, overheads and carrying costs. Direct costs include, among other things, labour costs, purchased services, equipment costs and material costs. Attributable indirect costs and overheads include incremental long-term variable costs resulting from the execution of capital projects. Indirect costs include largely local crew facilities, highway vehicles, work trains and area management costs. Overheads primarily include a portion of the cost of the Company’s engineering department which plans, designs and administers these capital projects. These costs are allocated to projects by applying a measure consistent with the nature of the cost based on cost studies. For replacement properties, the project costs are allocated to dismantling and installation based on cost studies. Dismantling work is performed concurrently with the installation.
	Ballast programs including undercutting, shoulder ballasting and renewal programs which form part of the annual track program are capitalized as this work, and the related added ballast material, significantly improves drainage which in turn extends the life of ties and other track materials. These costs are tracked separately from the underlying assets and depreciated over the period to the next estimated similar ballast program. Spot replacement of ballast is considered a repair which is expensed as incurred.
	The costs of large refurbishments are capitalized and locomotive overhauls are expensed as incurred.
	The Company capitalizes development costs for major new computer systems.
	The Company follows group depreciation which groups assets which are similar in nature and have similar economic lives. The property groups are depreciated based on their expected economic lives determined by studies of historical retirements of properties in the group and engineering estimates of changes in current operations and of technological advances. Actual use and retirement of assets may vary from current estimates, which would impact the amount of depreciation expense recognized in future periods.
	When depreciable property is retired or otherwise disposed of in the normal course of business, the book value, less net salvage proceeds, is charged to accumulated depreciation and if different than the assumptions under the depreciation study could potentially result in adjusted depreciation expense over a period of years. However, when removal costs exceed the salvage value on assets and the Company has no legal obligation to remove the assets, the removal costs incurred are charged to income in the period in which the assets are removed and are not charged to accumulated depreciation.
	For the sale or retirement of larger groups of depreciable assets that are unusual and were not considered in depreciation studies, CP records a gain or loss for the difference between net proceeds and net book value of the assets sold or retired.
	Depreciation is calculated on the straight-line basis at rates based on the estimated service life, taking into consideration the projected annual usage of depreciable property, except for rail and other track material in the U.S., which is based directly on usage.
	Equipment under capital lease is included in Properties and depreciated over the period of expected use.
Assets held for sale	'
	Assets held for sale
	Assets to be disposed that meet the held for sale criteria are reported at the lower of their carrying amount and fair value, less costs to sell, and are no longer depreciated.
Goodwill and intangible assets	'
	Goodwill and intangible assets
	Goodwill represents the excess of the purchase price over the fair value of identifiable net assets upon acquisition of a business. Goodwill is assigned to the reporting units that are expected to benefit from the business acquisition which, after integration of operations with the railway network, may be different than the acquired business.
	The carrying value of goodwill, which is not amortized, is assessed for impairment annually in the fourth quarter of each year, or more frequently as economic events dictate. The fair value of the reporting unit is compared to its carrying value, including goodwill. If the fair value of the reporting unit is less than its carrying value goodwill is potentially impaired. The impairment charge that would be recognized is the excess of the carrying value of the goodwill over the fair value of the goodwill, determined in the same manner as in a business combination.
	Intangible assets with finite lives are amortized on a straight-line basis over the estimated useful lives of the respective assets. Favourable leases, customer relationships and interline contracts have amortization periods ranging from 15 to 20 years. When there is a change in the estimated useful life of an intangible asset with a finite life, amortization is adjusted prospectively.
Financial instruments	'
	Financial instruments
	Financial instruments are contracts that give rise to a financial asset of one party and a financial liability or equity instrument of another party.
	Financial instruments are recognized initially at fair value, which is the amount of consideration that would be agreed upon in an arm’s length transaction between willing parties.
	Subsequent measurement depends on how the financial instruments have been classified. Accounts receivable and investments, classified as loans and receivables, are measured at amortized cost, using the effective interest method. Certain equity investments, classified as available for sale, are recognized at cost as fair value cannot be reliably established. Cash and cash equivalents are classified as held for trading and are measured at fair value. Accounts payable, accrued liabilities, short-term borrowings, dividends payable, other long-term liabilities and long-term debt, classified as other liabilities, are also measured at amortized cost.
Derivative financial instruments	'
	Derivative financial instruments
	Derivative financial and commodity instruments may be used from time to time by the Company to manage its exposure to risks relating to foreign currency exchange rates, stock-based compensation, interest rates and fuel prices. When CP utilizes derivative instruments in hedging relationships, CP identifies, designates and documents those hedging transactions and regularly tests the transactions to demonstrate effectiveness in order to continue hedge accounting.
	All derivative instruments are classified as held for trading and recorded at fair value. Any change in the fair value of derivatives not designated as hedges is recognized in the period in which the change occurs in the Consolidated Statements of Income in the line item to which the derivative instrument is related. On the Consolidated Balance Sheets they are classified in “Other assets”, “Other long-term liabilities”, “Other current assets” or “Accounts payable and accrued liabilities” as applicable. Gains and losses arising from derivative instruments affect the following income statement lines: “Revenues”, “Compensation and benefits”, “Fuel”, “Other income and charges”, and “Net interest expense”.
	For fair value hedges, the periodic changes in values are recognized in income, on the same line as the changes in values of the hedged items are also recorded. For a cash flow hedge, the change in value of the effective portion is recognized in “Other comprehensive income”. Any ineffectiveness within an effective cash flow hedge is recognized in income as it arises in the same income account as the hedged item. Should a cash flow hedging relationship become ineffective, previously unrealized gains and losses remain within “Accumulated other comprehensive loss” until the hedged item is settled and, prospectively, future changes in value of the derivative are recognized in income. The change in value of the effective portion of a cash flow hedge remains in “Accumulated other comprehensive loss” until the related hedged item settles, at which time amounts recognized in “Accumulated other comprehensive loss” are reclassified to the same income or balance sheet account that records the hedged item.
	In the Consolidated Statements of Cash Flows, cash flows relating to derivative instruments designated as hedges are included in the same line as the related hedged items.
	The Company from time to time enters into foreign exchange forward contracts to hedge anticipated sales in U.S. dollars, the related accounts receivable and future capital acquisitions. Foreign exchange translation gains and losses on foreign currency-denominated derivative financial instruments used to hedge anticipated U.S. dollar-denominated sales are recognized as an adjustment of the revenues when the sale is recorded. Those used to hedge future capital acquisitions are recognized as an adjustment of the property amount when the acquisition is recorded.
	The Company also occasionally enters into foreign exchange forward contracts as part of its short-term cash management strategy. These contracts are not designated as hedges due to their short-term nature and are carried on the Consolidated Balance Sheets at fair value. Changes in fair value are recognized in income in the period in which the changes occur.
	The Company enters into interest rate swaps to manage the risk related to interest rate fluctuations. These swap agreements require the periodic exchange of payments without the exchange of the principal amount on which the payments are based. Interest expense on the debt is adjusted to include the payments owing or receivable under the interest rate swaps.
	The Company from time to time enters into bond forwards to fix interest rates for anticipated issuances of debt. These agreements are usually accounted for as cash flow hedges with gains and losses recorded in “Accumulated other comprehensive loss” and amortized to “Net interest expense” in the period that interest on the related debt is charged.
	The Company entered into derivatives called Total Return Swaps (“TRS”) to mitigate fluctuations in tandem share appreciation rights (“TSAR”), deferred share units (“DSU”) and restricted share units (“RSU”). These were not designated as hedges and were recorded at market value with the offsetting gain or loss reflected in “Compensation and benefits”.
Restructuring accrual	'
	Restructuring accrual
	Restructuring liabilities are recorded at their present value. The discount related to liabilities is amortized to “Compensation and benefits” over the payment period. Provisions for labour restructuring are recorded in “Other long-term liabilities”, except for the current portion, which is recorded in “Accounts payable and accrued liabilities”.
Environmental remediation	'
	Environmental remediation
	Environmental remediation accruals, recorded on an undiscounted basis, cover site-specific remediation programs. Provisions for environmental remediation costs are recorded in “Other long-term liabilities”, except for the current portion, which is recorded in “Accounts payable and accrued liabilities”.
Income taxes	'
	Income taxes
	The Company follows the liability method of accounting for income taxes. Deferred income tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect of a change in income tax rates on deferred income tax assets and liabilities is recognized in income in the period during which the change occurs.
	When appropriate, the Company records a valuation allowance against deferred tax assets to reflect that these tax assets may not be realized. In determining whether a valuation allowance is appropriate, CP considers whether it is more likely than not that all or some portion of CP’s deferred tax assets will not be realized, based on management’s judgment using available evidence about future events.
	At times, tax benefit claims may be challenged by a tax authority. Tax benefits are recognized only for tax positions that are more likely than not sustainable upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in CP’s tax returns that do not meet these recognition and measurement standards.
	Investment and other similar tax credits are deferred on the Consolidated Balance Sheets and amortized to “Income tax expense” as the related asset is recognized in income.
Earnings per share	'
	Earnings per share
	Basic earnings per share are calculated using the weighted average number of Common Shares outstanding during the year. Diluted earnings per share are calculated using the treasury stock method for determining the dilutive effect of options.
Stock-based compensation	'
	Stock-based compensation
	CP follows the fair value based approach to account for stock options. Compensation expense and an increase in additional paid-in capital are recognized for stock options over their vesting period, or over the period from the grant date to the date employees become eligible to retire when this is shorter than the vesting period, based on their estimated fair values on the grant date, as determined using the Black-Scholes option-pricing model.
	With the granting of regular stock options, some employees have been simultaneously granted share appreciation rights, which provide the employee the choice to either exercise the stock option for shares, or to exercise the TSAR and thereby receive the intrinsic value of the stock option in cash. Options with TSARs are awards that may call for settlement in cash and, therefore, are recorded as liabilities. CP follows the fair value based approach, as determined by the Black-Scholes option pricing model, to account for the TSAR liability. The liability is fair valued and changes in the liability are recorded in “Compensation and benefits” over the vesting period, or over the period from the grant date to the date employees become eligible to retire when this is shorter than the vesting period, until exercised. If an employee chooses to exercise the option, thereby cancelling the TSAR, both the exercise price and the liability are settled to “Share capital”.
	Forfeitures of options and tandem options are estimated at issuance and subsequently at the balance sheet date.
	Any consideration paid by employees on exercise of stock options is credited to share capital when the option is exercised and the recorded fair value of the option is removed from additional paid-in capital and credited to share capital.
	Compensation expense is also recognized for TSARs, DSUs, performance share units (“PSUs”) and RSUs using the fair value method. Forfeitures of TSARs, DSUs, PSUs and RSUs are estimated at issuance and subsequently at the balance sheet date.
	The employee share purchase plan (“ESPP”) gives rise to compensation expense that is recognized using the issue price by amortizing the cost over the vesting period or over the period from the grant date to the date employees become eligible to retire when this is shorter than the vesting period.

	(a) Dakota, Minnesota & Eastern Railroad – West
	On January 2, 2014, the Company executed an agreement with Genesee & Wyoming Inc. (“G&W”) for the sale of a portion of CP’s DM&E line between Tracy, Minnesota and Rapid City, South Dakota, Colony, Wyoming and Crawford, Nebraska and connecting branch lines (“DM&E West”). The sale, which is subject to regulatory approval by the U.S. Surface Transportation Board, is expected to generate approximately US$215 million in gross proceeds, subject to closing adjustments, and is expected to close in 2014.
	At December 31, 2013, CP has classified DM&E West as an asset held for sale carried at CDN$222 million, being its estimated fair value less estimated direct selling costs. As a result, in the fourth quarter of 2013, the Company recorded an asset impairment charge and accruals for future costs associated with the sale totaling CDN$435 million ($257 million after-tax). The components of the asset impairment charge and charge for the accruals, which are subject to closing adjustments, that were recorded against income as “Asset impairments” are as follows:
	(in millions of Canadian dollars)	2013
	Property, plant and equipment	$	426
	Intangible assets		2
	Goodwill		6
	Total asset impairment charge		434
	Accruals for future costs		1
	Total charge	$	435
	(b) Powder River Basin impairment
	As part of the acquisition of DM&E in 2007, CP acquired the option to build a 260 mile extension of its network into coal mines in the Powder River Basin (“PRB”).
	Due to continued deterioration in the market for domestic thermal coal, including a sharp deterioration in 2012, in the fourth quarter of 2012 CP deferred plans to extend its rail network into the PRB coal mines indefinitely. As a result of this decision and in light of the declined market conditions, CP has evaluated the recoverability of the carrying amount of PRB assets and determined that this exceeded the estimated fair value by $180 million. The estimated fair value represents the expected proceeds from the sale of the acquired land, as determined by a comparable market assessment. Other costs associated with the acquisition of DM&E and accumulated by CP since acquisition have been written down to $nil. The amount of the impairment associated with this indefinite deferral was $180 million ($107 million after-tax). The components of the PRB impairment that were charged against income as “Asset impairments” in 2012 are as follows:
	(in millions of Canadian dollars)	2012
	Option impairment (Note 15)	$	26
	Construction plans, including capitalized interest		134
	Land, land option appraisals, including capitalized interest		20
	Total impairment	$	180
	(c) Impairment loss on locomotives
	In the fourth quarter of 2012, CP reached a decision to dispose of a certain series of locomotives to improve operating efficiencies, and accordingly performed an impairment test on these assets. The impairment test determined that the net book value of these locomotives exceeded their estimated fair value by $80 million. The estimated fair value represents the expected future cashflows from the disposal of these locomotives. The impairment charge of $80 million ($59 million after tax) was recorded in “Asset impairments” and charged against income.

K.  During November 2013, CP extended its revolving credit agreement, dated October 31, 2011, by three years to November 29, 2018. The amended agreement is with 13 highly rated financial institutions for a committed amount of $1.165 billion and also contains an uncommitted accordion feature to a maximum size of $1.5 billion. The agreement can accommodate draws of cash and/or letters of credit at pre-agreed pricing. At December 31, 2013, the facility was undrawn. The weighted average annualized interest rate of the facility for drawn funds was not applicable in 2013 compared to 2.94% in 2012 and 1.98% in 2011. The agreement requires the Company not to exceed a maximum debt to total capitalization ratio. At December 31, 2013, the Company satisfied this threshold stipulated in the financial covenant.

Under these agreements, the Company has the option to post collateral in the form of cash or cash equivalents, equal at least to the face value of the letter of credit issued. Collateral provided includes highly liquid investments purchased three months or less from maturity and is stated at cost, which approximates market value and is shown separately on the balance sheet as “Restricted cash and cash equivalents”.
At December 31, 2013, under its bilateral facilities the Company had letters of credit drawn of $394 million from a total available amount of $585 million. Prior to these bilateral agreements, letters of credit were drawn under the Company’s revolving credit facility. At December 31, 2013, cash and cash equivalents of $411 million were pledged as collateral and recorded as “Restricted cash and cash equivalents”, $nil in 2012.

	(1) Government & Corporate Bonds:
	Fair values for bonds are based on market prices supplied by independent pricing sources as of the last trading day.
	Mortgages: The fair value measurement of $52 million (2012 – $34 million) of mortgages categorized as Level 2 is based on current market yields of financial instruments of similar maturity, coupon and risk factors.
	(2) Real Estate:
	The fair value of real estate investments of $847 million (2012 – $779 million) is based on property appraisals which use a number of approaches that typically include a discounted cash flow analysis, a direct capitalization income method and/or a direct comparison approach. Appraisals of real estate investments are generally performed semi-annually by qualified external accredited appraisers. There are no unfunded commitments for real estate as at December 31, 2013.
	Infrastructure:
	Infrastructure fund values of $314 million (2012 – $333 million) are based on the fair value of the fund assets as calculated by the fund manager, generally using a discounted cash flow analysis that takes into account current market conditions and recent sales transactions where practical and appropriate. As at December 31, 2013, unfunded commitments for the infrastructure funds were $23 million (2012 – $24 million).
	(3) Absolute Return:
	The fair value of absolute return investments is based on the net asset value reported by the fund administrators. The funds have different redemption policies and periods. All hedge fund investments have contractual redemption frequencies, ranging from monthly to tri-annually, and redemption notice periods varying from 30 to 95 days. Hedge fund investments that have redemption dates less frequent than every four months or have restrictions on contractual redemption features at the reporting date are classified as Level 3. There are no unfunded commitments for absolute return fund investments as at December 31, 2013.
	¨	Funds of hedge funds invest in a portfolio of hedge funds that allocate capital across a broad array of funds and/or investment managers.
	¨	Multi-strategy funds include funds that invest in broadly diversified portfolios of equity, fixed income and derivative instruments.
	¨	Credit funds invest in an array of fixed income securities.
	¨	Equity funds invest primarily in U.S. and global equity securities.
	(4) At December 31, 2013, derivatives were primarily being used to partially hedge foreign currency exposures. The Company’s pension funds may utilize the following derivative instruments: equity futures to replicate equity index returns (Level 2); currency forwards to partially hedge foreign currency exposures (Level 2); bond forwards to reduce asset/liability interest rate risk exposures (Level 2); interest rate swaps to manage duration and interest rate risk (Level 2); credit default swaps to manage credit risk (Level 2); and options to manage interest rate risk and volatility (Level 2).

[1]	Dakota, Minnesota & Eastern Railroad - West On January 2, 2014, the Company executed an agreement with Genesee & Wyoming Inc. ("G&W") for the sale of a portion of CP's DM&E line between Tracy, Minnesota and Rapid City, South Dakota, Colony, Wyoming and Crawford, Nebraska and connecting branch lines ("DM&E West"). The sale, which is subject to regulatory approval by the U.S. Surface Transportation Board, is expected to generate approximately US$215 million in gross proceeds, subject to closing adjustments, and is expected to close in 2014. At December 31, 2013, CP has classified DM&E West as an asset held for sale carried at CDN$222 million, being its estimated fair value less estimated direct selling costs. As a result, in the fourth quarter of 2013, the Company recorded an asset impairment charge and accruals for future costs associated with the sale totaling CDN$435 million ($257 million after-tax). The components of the asset impairment charge and charge for the accruals, which are subject to closing adjustments, that were recorded against income as "Asset impairments" are as follows: (in millions of Canadian dollars) 2013 Property, plant and equipment $ 426 Intangible assets 2 Goodwill 6 Total asset impairment charge 434 Accruals for future costs 1 Total charge $ 435
[2]	Includes impairment of other investment of $5 million
[3]	Powder River Basin impairment As part of the acquisition of DM&E in 2007, CP acquired the option to build a 260 mile extension of its network into coal mines in the Powder River Basin ("PRB"). Due to continued deterioration in the market for domestic thermal coal, including a sharp deterioration in 2012, in the fourth quarter of 2012 CP deferred plans to extend its rail network into the PRB coal mines indefinitely. As a result of this decision and in light of the declined market conditions, CP has evaluated the recoverability of the carrying amount of PRB assets and determined that this exceeded the estimated fair value by $180 million. The estimated fair value represents the expected proceeds from the sale of the acquired land, as determined by a comparable market assessment. Other costs associated with the acquisition of DM&E and accumulated by CP since acquisition have been written down to $nil. The amount of the impairment associated with this indefinite deferral was $180 million ($107 million after-tax). The components of the PRB impairment that were charged against income as "Asset impairments" in 2012 are as follows: (in millions of Canadian dollars) 2012 Option impairment (Note 15) $ 26 Construction plans, including capitalized interest 134 Land, land option appraisals, including capitalized interest 20 Total impairment $ 180
[4]	Impairment loss on locomotives In the fourth quarter of 2012, CP reached a decision to dispose of a certain series of locomotives to improve operating efficiencies, and accordingly performed an impairment test on these assets. The impairment test determined that the net book value of these locomotives exceeded their estimated fair value by $80 million. The estimated fair value represents the expected future cashflows from the disposal of these locomotives. The impairment charge of $80 million ($59 million after tax) was recorded in "Asset impairments" and charged against income.

[1]	Government & Corporate Bonds: Fair values for bonds are based on market prices supplied by independent pricing sources as of the last trading day. Mortgages: The fair value measurement of $52 million (2012 - $34 million) of mortgages categorized as Level 2 is based on current market yields of financial instruments of similar maturity, coupon and risk factors.
[2]	Real Estate: The fair value of real estate investments of $847 million (2012 - $779 million) is based on property appraisals which use a number of approaches that typically include a discounted cash flow analysis, a direct capitalization income method and/or a direct comparison approach. Appraisals of real estate investments are generally performed semi-annually by qualified external accredited appraisers. There are no unfunded commitments for real estate as at December 31, 2013. Infrastructure: Infrastructure fund values of $314 million (2012 - $333 million) are based on the fair value of the fund assets as calculated by the fund manager, generally using a discounted cash flow analysis that takes into account current market conditions and recent sales transactions where practical and appropriate. As at December 31, 2013, unfunded commitments for the infrastructure funds were $23 million (2012 - $24 million).
[3]	Absolute Return: The fair value of absolute return investments is based on the net asset value reported by the fund administrators. The funds have different redemption policies and periods. All hedge fund investments have contractual redemption frequencies, ranging from monthly to tri-annually, and redemption notice periods varying from 30 to 95 days. Hedge fund investments that have redemption dates less frequent than every four months or have restrictions on contractual redemption features at the reporting date are classified as Level 3. There are no unfunded commitments for absolute return fund investments as at December 31, 2013. B( Funds of hedge funds invest in a portfolio of hedge funds that allocate capital across a broad array of funds and/or investment managers. B( Multi-strategy funds include funds that invest in broadly diversified portfolios of equity, fixed income and derivative instruments. B( Credit funds invest in an array of fixed income securities. B( Equity funds invest primarily in US and global equity securities.
[4]	At December 31, 2013, derivatives were primarily being used to partially hedge foreign currency exposures. The Company's pension funds may utilize the following derivative instruments: equity futures to replicate equity index returns (Level 2); currency forwards to partially hedge foreign currency exposures (Level 2); bond forwards to reduce asset/liability interest rate risk exposures (Level 2); interest rate swaps to manage duration and interest rate risk (Level 2); credit default swaps to manage credit risk (Level 2); and options to manage interest rate risk and volatility (Level 2).
