(m) Finance costs:

Under the Electricity Act 1998, the Corporation makes payments in lieu of corporate taxes to Ontario Electricity Financial Corporation. These payments are calculated in accordance with the rules for computing taxable income and taxable capital and other relevant amounts contained in the Income Tax Act (Canada) and the Corporation Tax Act (Ontario) as modified by the Electricity Act, 1998 and related regulations. Payments in lieu of taxes (“PILS”) are referred to as income taxes.

Current tax is the expected PILs payable on the taxable income for the year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment to tax payable in respect of previous years.

Deferred tax is recognized using the balance sheet method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax assets and liabilities are measured using enacted or substantively enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the consolidated statement of income in the year that includes the date of enactment or substantive enactment.

(o) Set-off and reporting on a net basis:

Assets and liabilities and income and expenses are not offset and reported on a net basis unless required or permitted by IFRS. For financial assets and financial liabilities, offsetting is permitted when, and only when, the Corporation has a legally enforceable right to set-off and intends either to settle on a net basis, or to realize the asset and settle the liability simultaneously.
