21. differences between Canadian and United States generally accepted accounting principles
The consolidated financial statements have been prepared in accordance with Canadian GAAP. The principles adopted in these financial statements conform in all material respects to those generally accepted in the United States except as summarized below. Significant differences between Canadian GAAP and U.S. GAAP would have the following effect on reported net income of the Company:

The following is an analysis of retained earnings (deficit) reflecting the application of U.S. GAAP:

The following is an analysis of major balance sheet categories reflecting the application of U.S. GAAP:

The following is a reconciliation of shareholders' equity incorporating the differences between Canadian and U.S. GAAP:

(a) Merger of BC TELECOM and TELUS
The business combination between BC TELECOM and TELUS Corporation (renamed TELUS Holdings Inc. which was wound up June 1, 2001) was accounted for using the pooling of interests method under Canadian GAAP. Under Canadian GAAP, the application of the pooling of interests method of accounting for the merger of BC TELECOM and TELUS Holdings Inc. resulted in a restatement of prior periods as if the two companies had always been combined. Under U.S. GAAP, the merger is accounted for using the purchase method. Use of the purchase method results in TELUS (TELUS Holdings Inc.) being acquired by BC TELECOM for $4,662.4 million (including merger related costs of $51.9 million) effective January 31, 1999.
(b) Operating expenses – Operations

Future employee benefits: Under U.S. GAAP, TELUS' future employee benefit assets and obligations have been recorded at their fair values on acquisition. Accounting for future employee benefits under Canadian GAAP changed to become more consistent with U.S. GAAP effective January 1, 2000. Canadian GAAP provides that the transitional balances can be accounted for prospectively. Therefore, to conform to U.S. GAAP, the amortization of the transitional amount needs to be removed from the future employee benefit expense.
Share-based compensation: Effective January 1, 2004, Canadian
GAAP required the adoption of the fair value method of accounting for
share-based compensation for awards made after 2001 (see Note 2(a)
and Note 9(a)).
U.S. GAAP requires disclosure of the impact on net
income and net income per Common Share and Non-Voting Share as if
the fair value based method of accounting had been applied for awards
made after 1994; the Company continues to use the intrinsic value
method for purposes of U.S. GAAP. The fair values of the Company's
options granted in 2004 and 2003, and the weighted average assumptions
used in estimating the fair values, are set out in Note 9(a). Such
impact, using the fair values set out in Note 9(a), would approximate the
pro forma amounts in the following table.

(c) Operating expenses – Depreciation

Merger of BC TELECOM and TELUS: Under the purchase method, TELUS' capital assets on acquisition have been recorded at fair value rather than at their underlying cost (book values) to TELUS. Therefore, depreciation of such assets based on fair values at the date of acquisition under U.S. GAAP will be different than TELUS' depreciation based on underlying cost (book values). As of March 31, 2004, the amortization of this difference had been completed.
Asset impairment: In the first quarter of 1998, BC TELECOM took an asset impairment charge. In assessing if a capital asset is impaired, estimated future net cash flows are not discounted in computing the net recoverable amount. Under Canadian GAAP, at the time the assessment took place, the impairment amount recorded was the excess of the carrying amount over the recoverable amount; under U.S. GAAP the impairment amount recorded was the excess of the carrying amount over the discounted estimated future net cash flows that were used to determine the net recoverable amount. Under U.S. GAAP, the net of tax charge taken in 1998 would be $232.2 million higher and would not be considered an extraordinary item. The annual depreciation expense would be approximately $72 million lower subsequent to when the increased impairment charge was taken under U.S. GAAP. As of December 31, 2003, the amortization of this difference had been completed.
(d) Operating expenses – Amortization of intangible assets
As TELUS' intangible assets on acquisition have been recorded at their fair value (see (a)), amortization of such assets, other than for those with indefinite lives, needs to be included under U.S. GAAP; consistent with prior years, amortization is calculated using the straight-line method.
The incremental amounts recorded as intangible assets arising from the TELUS acquisition above are as follows:

Estimated aggregate amortization expense for intangible assets subject to amortization, calculated upon such assets held as at December 31, 2004, for each of the next five fiscal years is as follows:

(e) Goodwill
Merger of BC TELECOM and TELUS: Under the purchase method of accounting, TELUS' assets and liabilities at acquisition (see (a)) have been recorded at their fair values with the excess purchase price being allocated to goodwill in the amount of $403.1 million. Commencing January 1, 2002, rather than being systematically amortized, the carrying value of goodwill is periodically tested for impairment.
Additional goodwill on Clearnet purchase: Under U.S. GAAP, shares issued by the acquirer to effect an acquisition are measured at the date the acquisition was announced; however, under Canadian GAAP, at the time the transaction took place, shares issued to effect an acquisition were measured at the transaction date. This results in the purchase price under U.S. GAAP being $131.4 million higher than under Canadian GAAP. The resulting difference is assigned to goodwill. Commencing January 1, 2002, rather than being systematically amortized, the carrying value of goodwill is periodically tested for impairment.
(f) Financing costs
Merger of BC TELECOM and TELUS: Under the purchase method, TELUS' long-term debt on acquisition has been recorded at its fair value rather than at its underlying cost (book value) to TELUS. Therefore, interest expense calculated on the debt based on fair values at the date of acquisition under U.S. GAAP will be different than TELUS' interest expense based on underlying cost (book value).
Convertible debentures: Under Canadian GAAP, the conversion option embedded in the convertible debentures is presented separately as a component of shareholders' equity. Under U.S. GAAP, the embedded conversion option is not subject to bifurcation and is thus presented as a liability along with the balance of the convertible debentures. The principal accretion occurring under Canadian GAAP is not required under U.S. GAAP and the adjustment is included in the interest expense adjustment in the reconciliation.
(g) Accounting for derivatives
On January 1, 2001, the Company adopted, for U.S. GAAP purposes, the provisions of Statement of Financial Accounting Standards No. 133, Accounting For Derivative Instruments and Hedging Activities. This standard requires that all derivatives be recognized as either assets or liabilities and measured at fair value. This is different from the Canadian GAAP treatment for financial instruments. Under U.S. GAAP, derivatives which are fair value hedges, together with the financial instrument being hedged, will be marked to market with adjustments reflected in income and derivatives which are cash flow hedges will be marked to market with adjustments reflected in comprehensive income (see (i)).
(h) Income taxes

The Company's income tax expense (recovery), for U.S. GAAP purposes, differs from that calculated by applying statutory rates for the following reasons:

As referred to in Note 1(b), the Company must make significant estimates in respect of the composition of its future income tax assets and future income tax liabilities. The operations of the Company are complex, and related tax interpretations, regulations and legislation are continually changing. As a result, there are usually some tax matters in question.
Temporary differences comprising the deferred tax assets (liabilities) are estimated as follows:

(i) Additional disclosures required under U.S. GAAP – Comprehensive income
Statement of Financial Accounting Standards No. 130, Reporting Comprehensive Income, requires that a statement of comprehensive income be displayed with the same prominence as other financial statements. Comprehensive income, which incorporates net income, includes all changes in equity during a period except those resulting from investments by and distributions to owners. There is currently no requirement to disclose comprehensive income under Canadian GAAP.

(j) Recently issued accounting standards not yet implemented
Equity-based compensation: Under U.S. GAAP, effective for the third quarter of its 2005 fiscal year, the Company will be required to apply the fair value method of accounting for share-based compensation awards granted to employees, as prescribed by SFAS 123(R). As compared with the information that has been previously and currently disclosed for U.S. GAAP purposes, the adoption of this standard will result in a reclassification between share capital, contributed surplus and retained earnings. The Company expects that it will use the modified prospective transition method. The Company is in the process of estimating the impact on the U.S. GAAP reconciliation disclosures, but has not yet finalized the amounts; such amount would be in excess of the $176.9 million in share option expense reported in the U.S. GAAP reconciliation disclosures for the fiscal years ended December 31, 2004–1999, inclusive, due to the initial effective date of SFAS 123.
Other: As would affect the Company, there are no other U.S. accounting standards currently issued and not yet implemented that would differ from Canadian accounting standards currently issued and not yet implemented.
