v) Financial income (expenses)
These include interest, and monetary and exchange variations arising from short-term investments, derivative transactions, loans, financing, debentures, present value adjustments of transactions that generate monetary assets and liabilities and other financial transactions. These are recognized on an accrual basis when earned or incurred by the Company.
For all financial instruments measured at amortized cost and interest-yielding financial assets classified as available for sale, interest income or expense is recognized using the effective interest method, which exactly discounts estimated future cash payments or receipts over the expected life of the financial instrument or, where appropriate, a shorter period, to the net carrying amount of the financial asset or liability.
