The Corporation is subject to variable interest rate cash flow risk with respect to its investments. The Corporation has addressed this risk by entering into fixed interest rates on invested funds and debts.

(vi) Currency risk:

Currency risk is the risk that the fair value or future cash flow of a financial instrument will fluctuate due to changes in foreign exchange rates. The Corporation is exposed to currency risk through its foreign currency denominated bank and investment accounts. A weakening or strengthening of the Canadian dollar can affect the cash flows. This risk is monitored by investment managers and the exposure is limited to these accounts. For sensitivity purposes, a 1% change in the Canadian dollar would result in a change of $11 (2018 - $9) on the consolidated balance sheet and consolidated statement of income.
