(h) Income taxes
Current income taxes are recognized with respect to amounts expected to be paid or recovered under the tax rates and laws that have been enacted or substantively enacted at the balance sheet date.
Deferred income taxes are accounted for using the liability method. Under this method, deferred income tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities in the consolidated financial statements and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted or substantively enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred income tax assets and liabilities is recognized in income in the period that includes the substantive enactment date. A deferred tax asset is recognized initially when it is probable that future taxable income will be sufficient to use the related tax benefits and may be subsequently reduced, if necessary, to an amount that is more likely than not to be realized. A deferred tax expense or benefit is recognized in other comprehensive income or otherwise directly in equity to the extent that it relates to items that are recognized in other comprehensive income or directly in equity in the same or a different period.
In the course of the Corporation’s operations, there are a number of uncertain tax positions due to the complexity of certain transactions and due to the fact that related tax interpretations and legislation are continually changing. When a tax position is uncertain, the Corporation recognizes an income tax benefit or reduces an income tax liability only when it is probable that the tax benefit will be realized in the future or that the income tax liability is no longer probable.
