(k) Interest revenue and expense:
Interest revenue and expenses are recognized in the income statement using the effective interest rate method. The effective interest rate is the rate which exactly discounts estimated future cash payments or receipts through the expected life of the financial instrument or a shorter period, where appropriate, to the net carrying amount of the financial asset or financial liability. To calculate the effective interest rate, the Bank determines cash flows by taking into account all contractual conditions of the financial instrument, excluding future credit losses.
The effective interest rate calculation includes all fees and other amounts paid or received that form part of the effective interest rate. Transaction costs include incremental costs that are directly attributable to the purchase or issuance of a financial asset or liability.
