Final settlement price

The final settlement price shall be determined by the Bourse and shall be equal to 100 minus the compounded daily overnight repo rate (CORRA) expressed in terms of an overnight repo rate index and calculated over the period of the contract month that begins the day following the last Bank of Canada fixed announcement date to the day of the next Bank of Canada fixed announcement date. Weekend and holiday rates are considered to be the rate applicable on the previous business day for which a rate was reported. For example, Friday's rate is used for Saturday and Sunday rates.

The daily overnight repo rate (CORRA) is calculated and reported by the Bank of Canada.
