If provision for these taxes had been made, future income tax liabilities would increase by approximately $61 million at December 31, 2005 (2004 - $57 million). Income Tax Payments Income tax payments of $530 million were made during the year ended December 31, 2005 (2004 - $419 million; 2003 - $220 million). 96 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS NOTE 19 NOTES PAYABLE 2005 2004 Weighted Weighted Average Average Interest Rate Interest Rate Outstanding Per Annum at Outstanding Per Annum at December 31(1) December 31 December 31(1) December 31 Canadian dollars 765 3.4% 546 2.6% U.S. dollars (2005 - US$169) 197 4.5% - - 962 546 (1) Amounts outstanding are stated in millions of Canadian dollars; amounts denominated in currencies other than Canadian dollars are stated in millions. Notes payable consists of commercial paper and line of credit drawings. At December 31, 2005, total credit facilities of $2.0 billion were available to support the Company's commercial paper programs and for general corporate purposes. Of this total, $1.5 billion was a committed five-year term syndicated credit facility. This facility is extendible on an annual basis and is revolving. In December 2005, the facility was extended to December 2010. The remaining amounts are either demand or non-extendible facilities. At December 31, 2005, the Company had used approximately $271 million of its total lines of credit for letters of credit and to support its ongoing commercial arrangements. If drawn, interest on the lines of credit is charged at prime rates of Canadian chartered and U.S. banks and at other negotiated financial bases. The cost to maintain the unused portion of the lines of credit was $2 million for the year ended December 31, 2005 (2004 - $2 million). NOTE 20 ASSET RETIREMENT OBLIGATIONS At December 31, 2005, the estimated undiscounted cash flows required to settle the asset retirement obligations with respect to Gas Transmission were $46 million (2004 - $48 million), calculated using an inflation rate ranging from two to three per cent per annum. The estimated fair value of this liability was $12 million (2004 - $12 million) after discounting the estimated cash flows at rates ranging from 5.5 per cent to 6.6 per cent. At December 31, 2005, the expected timing of payment for settlement of the obligations ranges from 12 to 24 years. No amount has been recorded for asset retirement obligations relating to the regulated natural gas transmission operation assets as it is not possible to make a reasonable estimate of the fair value of the liability due to the inability to determine the scope and timing of the asset retirements. Management believes it is reasonable to assume that all retirement costs associated with the regulated pipelines will be recovered through tolls in future periods. At December 31, 2005, the estimated undiscounted cash flows required to settle the asset retirement obligations with respect to the Power business were $95 million (2004 - $128 million), calculated using an inflation rate ranging from two to three per cent per annum. The estimated fair value of this liability was $21 million (2004 - $24 million) after discounting the estimated cash flows at rates ranging from 5.5 per cent to 6.6 per cent. At December 31, 2005, the expected timing of payment for settlement of the obligations ranges from 13 to 28 years. For the hydroelectric power plant assets, as it is not possible to make a reasonable estimate of the fair value of the liability due to the inability to determine the scope and timing of the asset retirements, no amount has been recorded for asset retirement obligations. For the Bruce Power nuclear assets, as the lessor is responsible for decommissioning liabilities under the lease agreement, no amount has been recorded for asset retirement obligations.

Benefits provided under the DB Plans are based on years of service and highest average earnings over three consecutive years of employment, and increase annually by a portion of the increase in the Consumer Products Index (CPI). Past service costs are amortized over the expected average remaining service life of employees, which is approximately 11 years. The Company also provides its employees with post-employment benefits other than pensions, including termination benefits and defined life insurance and medical benefits beyond those provided by government-sponsored plans. Past service costs are amortized over the expected average remaining life expectancy of former employees, which at December 31, 2005 was approximately 12 years. In 2005, the Company expensed $2 million (2004 - $1 million; 2003 - $1 million) related to retirement savings plans for its U.S. employees. Total cash payments for employee future benefits for 2005, consisting of cash contributed by the Company to the DB Plans and other benefit plans was $74 million (2004 - $89 million). 98 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS The Company measures its accrued benefit obligations and the fair value of plan assets for accounting purposes as at December 31 of each year. The most recent actuarial valuation of the pension plans for funding purposes was as of January 1, 2006, and the next required valuation is as of January 1, 2007.

Assumed projected rates of return are selected after analyzing historical experience and future expectations of the level and volatility of returns. Asset class benchmark returns, asset mix and anticipated benefit payments from plan assets are also considered in the determination of the overall expected rate of return. The discount rate is based on market interest rates of high quality bonds that match the timing and benefits expected to be paid under each plan. For measurement purposes, a 9.0 per cent annual rate of increase in the per capita cost of covered health care benefits was assumed for 2006. The rate was assumed to decrease gradually to 5.0 per cent for 2015 and remain at that level thereafter. A one percentage point increase or decrease in assumed health care cost trend rates would have the following effects.

The assets of the pension plans are managed on a going concern basis subject to legislative restrictions. The plans' investment policies are to maximize returns within an acceptable risk tolerance. Pension assets are invested in a diversified manner with consideration given to the demographics of the plans' participants. Employee Future Benefits of Joint Ventures Certain of the Company's joint ventures sponsor DB Plans, as well as post-employment benefits other than pensions, including defined life insurance and medical benefits beyond those provided by government-sponsored plans. The obligations of these plans are non-recourse to TCPL. The amounts that follow represent TCPL's proportionate share with respect to these plans. Total cash payments for employee future benefits for 2005, consisting of cash contributed by the Company's joint ventures to DB Plans and other benefit plans was $4 million (2004 - $1 million).

The operating lease agreement for the natural gas storage facility expires in 2030 with lessee termination rights every fifth anniversary commencing in 2010 and with the lessor having the right to terminate the agreement every five years commencing in 2015. Net rental expense on operating leases for the year ended December 31, 2005 was $17 million (2004 - $7 million; 2003 - $2 million). Bruce Power TCPL's share of Bruce A's signed commitments to third party suppliers for the next five years for the restart and refurbishment of the currently idle Units 1 and 2, extending the operating life of Unit 3 by replacing its steam generators and fuel channels when required and replacing the steam generators on Unit 4, is as follows. Year ended December 31 (millions of dollars) 2006 322 2007 311 2008 142 2009 69 2010 - 844 Aboriginal Pipeline Group On June 18, 2003, the Mackenzie Delta gas producers, the APG and TCPL reached an agreement which governs TCPL's role in the Mackenzie Gas Pipeline Project. The project would result in a natural gas pipeline being constructed from Inuvik, Northwest Territories, to the northern border of Alberta, where it would connect with the Alberta System. Under the agreement, TCPL agreed to finance the APG for its one-third share of project development costs. These costs were originally estimated to be approximately $90 million, but given extended project delays, the protracted regulatory process and the projected timing to reach a decision to construct the pipeline, this share is currently forecasted to increase to approximately $145 million. As at December 31, 2005, TCPL had funded $87 million (2004 - $60 million) of this loan which is included in other assets. The ability to recover this investment is dependent upon the outcome of the project. Contingencies The Canadian Alliance of Pipeline Landowners' Associations and two individual landowners commenced an action in 2003 under Ontario's Class Proceedings Act, 1992, against TCPL and Enbridge Inc. for damages of $500 million alleged to arise from the creation of a control zone within 30 metres of the pipeline pursuant to Section 112 of the NEB Act. The Company believes the claim is without merit and will vigorously defend the action. The Company has made no provision for any potential liability. A liability, if any, would be dealt with through the regulatory process. The Company and its subsidiaries are subject to various other legal proceedings and actions arising in the normal course of business. While the final outcome of such legal proceedings and actions cannot be predicted with certainty, it is the opinion of Management that the resolution of such proceedings and actions will not have a material impact on the Company's consolidated financial position or results of operations. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 105 Guarantees The Company, together with Cameco Corporation and BPC Generation Infrastructure Trust (BPC), has severally guaranteed one-third of certain contingent financial obligations of Bruce B related to power sales agreements, operator licenses, the lease agreement and contractor services. The terms of the guarantees range from 2007 to 2018. As part of the reorganization of Bruce Power, including the formation of Bruce A and the commitment to restart and refurbish the Bruce A units, the Company, together with BPC, severally guaranteed one-half of certain contingent financial obligations of Bruce A related to the refurbishment agreement with the Ontario Power Authority and cost sharing and sublease agreements with Bruce B. The terms of the guarantees currently range from 2018 to 2019. TCPL's share of the exposure under these Bruce Power guarantees at December 31, 2005 was estimated to be approximately $652 million of a calculated maximum of $758 million. The current carrying amount of the liability related to these guarantees is nil and the fair value is approximately $17 million. TCPL has guaranteed the equity undertaking of a subsidiary which supports the payment, under certain conditions, of principal and interest on US$133 million of public debt obligations of TransGas. The Company has a 46.5 per cent interest in TransGas. Under the terms of the agreement, the Company severally with another major multinational company may be required to fund more than their proportionate share of debt obligations of TransGas in the event that the minority shareholders fail to contribute. Any payments made by TCPL under this agreement convert into share capital of TransGas. The potential exposure is contingent on the impact of any change of law on TransGas' ability to service the debt. From the issuance of the debt in 1995 to date, there has been no change in applicable law and thus no exposure to TCPL. The debt matures in 2010. The Company has made no provision related to this guarantee. In connection with the acquisition of GTN, US$241 million of the purchase price was deposited into an escrow account. As at December 31, 2005, there was US$54 million remaining in the escrow account. The outstanding funds in the escrow account represent the full face amount of the potential liability under certain GTN guarantees and are to be used to satisfy the liability of GTN under these designated guarantees. NOTE 24 DISCONTINUED OPERATIONS The Board of Directors approved plans in previous years to dispose of the Company's International, Canadian Midstream, Gas Marketing and certain other businesses. Net income from discontinued operations for the year ended December 31, 2005 was nil (2004 - $52 million, net of $27 million of income taxes; 2003 - $50 million, net of $29 million of income taxes). Included in accounts payable at December 31, 2005 was the remaining $51 million provision for loss on discontinued operations (2004 - $55 million). 106 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS SUPPLEMENTARY INFORMATION SIX YEAR FINANCIAL HIGHLIGHTS (millions of dollars except where 2005 2004 2003 2002 2001 2000 indicated) Income Statement Revenues 6,124 5,497 5,636 5,225 5,285 4,384 Net income from continuing 1,230 1,000 823 769 708 663 operations Net income 1,230 1,052 873 769 641 724 Results by segment Gas Transmission 684 586 622 653 585 623 Power 561 396 220 146 168 85 Corporate (37 ) (4 ) (41 ) (52 ) (67 ) (80 ) Continuing operations 1,208 978 801 747 686 628 Discontinued operations - 52 50 - (67 ) 61 Net income applicable to common 1,208 1,030 851 747 619 689 shares Cash Flow Statement Funds generated from operations 1,950 1,701 1,822 1,843 1,625 1,484 (Increase)/decrease in operating (48 ) 28 93 92 (487 ) 437 working capital Net cash provided by operations 1,902 1,729 1,915 1,935 1,138 1,921 Capital expenditures and 2,071 2,046 965 851 1,082 1,144 acquisitions Dividends on common and preferred 608 574 532 488 440 458 shares Balance Sheet Assets Plant, property and equipment Gas Transmission 16,774 17,385 16,122 16,158 16,562 16,937 Power 3,237 1,342 1,310 1,340 1,116 776 Corporate 27 37 50 64 66 111 Total assets 24,113 22,421 20,884 20,555 20,531 25,245 Capitalization Long-term debt 9,640 9,749 9,516 8,899 9,444 10,008 Long-term debt of joint ventures 937 808 741 1,193 1,262 1,280 Preferred securities 536 554 598 944 950 1,208 Preferred shares 389 389 389 389 389 389 Common shareholders' equity 7,164 6,484 6,044 5,747 5,426 5,211 SUPPLEMENTARY INFORMATION 107 2005 2004 2003 2002 2001 2000 Per Common Share Data (dollars) Net income - Basic Continuing operations $2.50 $2.03 $1.66 $1.56 $1.44 $1.32 Discontinued operations - 0.11 0.11 - (0.14 ) 0.13 $2.50 $2.14 $1.77 $1.56 $1.30 $1.45 Net income - Diluted Continuing operations $2.50 $2.03 $1.66 $1.55 $1.44 $1.32 Discontinued operations - 0.11 0.11 - (0.14 ) 0.13 $2.50 $2.14 $1.77 $1.55 $1.30 $1.45 Dividends declared $1.23 $1.17 $1.08 $1.00 $0.90 $0.80 Per Preferred Share Data (dollars) Series U Cumulative First $2.80 $2.80 $2.80 $2.80 $2.80 $2.80 Preferred Shares Series Y Cumulative First $2.80 $2.80 $2.80 $2.80 $2.80 $2.80 Preferred Shares Financial Ratios Earnings to fixed charges(1) 2.9 2.5 2.3 2.3 2.1 1.9 (1) The ratio of earnings to fixed charges is determined by dividing the income from continuing operations before financial charges and income taxes, excluding undistributed income from equity investees, by the financial charges incurred by the company (including capitalized interest). 108 SUPPLEMENTARY INFORMATION TRANSCANADA PIPELINES LIMITED RECONCILIATION TO UNITED STATES GAAP AUDITORS' REPORT ON RECONCILIATION TO UNITED STATES GAAP To the Shareholders of TransCanada PipeLines Limited On February 27, 2006, we reported on the consolidated balance sheets of TransCanada PipeLines Limited as at December 31, 2005 and 2004 and the consolidated statements of income, retained earnings and cash flows for each of the years in the three-year period ended December 31, 2005, which are included in the annual report on Form 40-F. In connection with our audits conducted in accordance with Canadian generally accepted auditing standards of the aforementioned consolidated financial statements, we also have audited the related supplemental note entitled "Reconciliation to United States GAAP" included in the Form 40-F. This supplemental note is the responsibility of the Company's management. Our responsibility is to express an opinion on this supplemental note based on our audits. In our opinion, such supplemental note, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein. /s/ KPMG LLP Chartered Accountants Calgary, Canada February 27, 2006 1 TRANSCANADA PIPELINES LIMITED RECONCILIATION TO UNITED STATES GAAP The 2005 audited consolidated financial statements of TransCanada PipeLines Limited (TCPL or the Company) have been prepared in accordance with Canadian generally accepted accounting principles (GAAP), which in some respects, differ from U.S. GAAP. The effects of these differences on the Company's consolidated financial statements for the year ended December 31, 2005 are provided in the following U.S. GAAP condensed consolidated financial statements which should be read in conjunction with TCPL's 2005 audited consolidated financial statements prepared in accordance with Canadian GAAP.

(2) Other expenses included an allowance for funds used during construction of $3 million for the year ended December 31, 2005 (2004 - $3 million; 2003 - $2 million). (3) The Company recorded its investment in TransCanada Power, L.P. (Power LP) using the proportionate consolidation method for Canadian GAAP purposes and as an equity investment for U.S. GAAP purposes. During the period from 1997 to April 2004, the Company was obligated to fund the redemption of Power LP units in 2017. As a result, under Canadian GAAP, TCPL accounted for the issuance of units by Power LP to third parties as a sale of a future net revenue stream and the resulting gains were deferred and amortized to income over the period to 2017. The redemption obligation was removed in April 2004 and the unamortized gains were 4 recognized as income. Under U.S. GAAP, any such gains in the period from 1997 to April 2004 are characterized as dilution gains and, because the Company was committed to fund the redemption of the units, the gains are recorded, on an after-tax basis, as equity transactions in shareholders' equity. The Company's accounting policy for dilution gains is to record them as income for both Canadian and U.S. GAAP purposes, however, U.S. GAAP requires such gains to be recorded directly in equity if there is a contemplation of reacquisition of units. With the removal of the redemption obligation in April 2004, subsequent issuances of units by Power LP are accounted for as dilution gains in income for both Canadian and U.S. GAAP purposes. (4) Correction of Error: In the period 1997 to 2001, the Company recorded certain transactions involving Power LP as sales of a revenue stream for both Canadian and U.S. GAAP purposes. For U.S. GAAP purposes, these transactions should have been accounted for as dilution gains (see footnote 3 above). This was corrected on a retroactive basis. The impact on previously reported amounts for U.S. GAAP purposes is as follows: (millions of dollars) 2005 2004 2003 Decrease in: Income from continuing operations - 135 10 Net income - 135 10 For U.S. GAAP purposes, the correction had no impact on the accumulated shareholders' equity at December 31, 2004 and the impact at December 31, 2003 was an increase of $135 million. (5) Under U.S. GAAP, a net loss recognized pursuant to Statement of Financial Accounting Standards (SFAS) No. 87 "Employers' Accounting for Pensions" as an additional pension liability not yet recognized as net period pension cost, must be recorded as a component of comprehensive income. As a result of recording an additional pension liability, the amounts recognized in the Company's balance sheet at December 31 are as follows. December 31 (millions of dollars) 2005 2004 Prepaid benefit cost 6 183 Regulatory asset 107 - Other assets 37 1 Accounts payable (70 ) (42 ) Deferred amounts (17 ) (18 ) Accumulated other comprehensive income 118 40 Net amount recognized 181 164 The accumulated benefit obligation for the Company's defined benefit pension plans was $1,123 million at December 31, 2005 (2004 - $943 million). (6) All foreign exchange and interest rate derivatives are recorded in the Company's consolidated financial statements at fair value under Canadian GAAP. Under the provisions of SFAS No. 133 "Accounting for Derivatives and Hedging Activities", all derivatives are recognized as assets and liabilities on the balance sheet and measured at fair value. For derivatives designated as fair value hedges, changes in the fair value are recognized in earnings together with an equal or lesser amount of changes in the fair value of the hedged item attributable to the hedged risk. For derivatives designated as cash flow hedges, changes in the fair value of the derivative that are effective in offsetting the hedged risk are recognized in other comprehensive income until the hedged item is recognized in earnings. Any ineffective portion of the change in fair value is also recognized in earnings each period. Substantially all of the amounts recorded in 2005, 2004 and 2003 as differences between U.S. and Canadian GAAP, for income from continuing operations, relate to the differences in accounting treatment with respect to the hedged item and, for comprehensive income, relate to cash flow hedges. Substantially all of the amounts recorded in the twelve months ended December 31, 2005, 2004 and 2003 as differences between U.S. and Canadian GAAP in respect of energy contracts relate to gains and losses on derivative energy contracts for periods before they were documented as hedges for purposes of U.S. GAAP and to differences in accounting with respect to physical energy contracts. During 2005, under the provisions of SFAS 133, net gains of $8 million (2004 - $10 million; 2003 - $47 million) from the hedges of changes in the fair value of long-term debt, and net losses of $8 million (2004 - $18 million; 2003 - $53 million) in the fair value of the hedged item were included in earnings for U.S. GAAP purposes as an adjustment to interest expense and foreign exchange losses. No amounts of the derivatives' gains or losses were excluded from the assessment of hedge effectiveness in fair value hedging relationships. No amounts were included in income in 2005, 2004, and 2003 with respect to ineffectiveness of cash flow hedges. For amounts included in other comprehensive income at December 31, 2005, $4 million (2004 - $(4) million; 2003 - $9 million) relates to the hedging of interest rate risk; $(1) million (2004 - $3 million; 2003 - $5 million) relates to the hedging of foreign exchange rate risk; and $(57) million (2004 - $2 million; 2003 - $ (6) million) relates to the hedging of energy price risk. Of these amounts, $(44) million is expected to be recorded in earnings during 2006. 5 At December 31, 2005, assets of $175 million (2004 - $29 million) and liabilities of $110 million (2004 - $27 million) were reduced for U.S. GAAP purposes to reflect the fair value of derivatives and the corresponding change in the fair value of hedged items. (7) Under Canadian GAAP, pre-operating costs incurred during the commissioning phase of a new project are deferred until commercial production levels are achieved. After such time, those costs are amortized over the estimated life of the project. Under U.S. GAAP, such costs are expensed as incurred. Certain start-up costs incurred by Bruce Power L.P. (Bruce B), an equity investment, are required to be expensed under U.S. GAAP. Under both Canadian GAAP and U.S. GAAP, interest is capitalized on expenditures relating to construction of development projects actively being prepared for their intended use. In Bruce B, under U.S. GAAP, the carrying value of development projects against which interest is capitalized is lower due to the expensing of pre-operating costs. (8) Financial Interpretation (FIN) 45 requires the recognition of a liability for the fair value of certain guarantees that require payments contingent on specified types of future events. The measurement standards of FIN 45 are applicable to guarantees entered into after January 1, 2003. For U.S. GAAP purposes, the fair value of guarantees recorded as a liability at December 31, 2005 was $17 million (2004 - $9 million) and relates to the Company's equity interest in Bruce B and Bruce Power A L.P. The net income impact with respect to the guarantees for the year ended December 31, 2005 was $1 million (2004 and 2003 - nil). (9) In accordance with U.S. GAAP, all current taxes are included in cash generated from operations. (10) Current assets at December 31, 2005 include derivative contracts of $49 million (2004 - $23 million) and hedging deferrals of $93 million (2004 - $10 million). (11) Under U.S. GAAP, the Company is required to record a deferred income tax liability for its cost-of-service regulated businesses. As these deferred income taxes are recoverable through future revenues, a corresponding regulatory asset is recorded for U.S. GAAP purposes. (12) Current liabilities at December 31, 2005 include dividends payable of $154 million (2004 - $146 million) and current taxes payable of $251 million (2004 - $260 million). Income Taxes The income tax effects of differences between the accounting value and the tax value of assets and liabilities are as follows. December 31 (millions of dollars) 2005 2004 Deferred Tax Liabilities Difference in accounting and tax bases of plant, equipment and power purchase arrangements 1,724 1,741 Taxes on future revenue requirement 874 914 Investments in subsidiaries and partnerships 555 438 Other 147 140 3,300 3,233 Deferred Tax Assets Net operating and capital loss carryforwards 1 7 Deferred amounts 148 89 Other 63 106 212 202 Less: Valuation allowance 14 17 198 185 Net deferred tax liabilities 3,102 3,048 Other In December 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123 (revised 2004) "Share-Based Payment" which requires all share-based payments to employees, including grants of employee stock options, to be recognized in the financial statements based on their fair values. The pro forma disclosures previously permitted under SFAS No. 123 no longer will be an alternative to financial statement recognition. In 2002, TCPL adopted accounting for its stock-based compensation plans using the fair value recognition 6 provisions under Canadian GAAP. Therefore, adopting the provisions under SFAS No 123 (revised 2004) has no impact on the U.S. GAAP financial statements of the Company. In March 2005, (FASB) issued a Staff Position (FSP) on a previously issued Financial Interpretation (FIN). The provisions of FSP FIN 46 (R)-5 "Implicit Variable Interests under revised FIN 46(R), Consolidation of Variable Interest Entities" require that a reporting enterprise consider consolidating implicit variable interests when applying the provisions of FIN 46(R). Adopting these provisions has had no impact on the U.S. GAAP financial statements of the Company. In March 2005, FASB issued FIN 47 "Accounting for Conditional Asset Retirement Obligations - an interpretation of FASB No.143". FIN 47 clarifies that the term "conditional asset retirement obligation" as used in SFAS No. 143, refers to a legal obligation to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity. It also clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. Adopting the clarification under this interpretation has had no impact on the U.S. GAAP financial statements of the Company. In May 2005, FASB issued SFAS No 154 "Accounting Changes and Error Corrections - a replacement of APB Opinion No. 20 and SFAS No. 3" which is effective for fiscal years beginning after December 15, 2005. SFAS No. 154 changes the requirements for the accounting for and reporting of a change in accounting principle and error correction. It establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transition requirements specific to the newly adopted accounting principle. Adopting the provisions under SFAS No. 154, as of January 1, 2006, is not expected to have an impact on the U.S. GAAP financial statements of the Company. Summarized Financial Information of Long-Term Investments The following summarized financial information of long-term investments includes those investments that are accounted for by the equity method under U.S. GAAP (including those that are accounted for by the proportionate consolidation method under Canadian GAAP).
