"do", the number of Business Days in the calculation period;
"i" is a series of whole numbers from one to do, each representing the relevant Business Day in chronological order from, and including, the first Business Day in the relevant Calculation Period;
ORRi = Overnight Repo Rate (CORRA) on the ith day of the calculation period (if the ith day is not a business day, the previous available CORRA is used);
"ni" is the number of calendar days in the relevant Calculation Period on which the rate is ORRi;
"d" is the number of calendar days in the relevant Calculation Period.

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.
The final settlement price is rounded to the nearest 1/10th of one basis point (0.001). In the case a decimal fraction ends with 0.0005 or higher, the final settlement price shall be rounded up.
The final settlement price is determined on the first business day following the last day of trading.
