61.5. When all Category A and B reserve emission units have been awarded and the total of the remaining offers to purchase Category C units is in excess of the quantity of Category C reserve emission units available, the Minister allocates the emission units(1) by establishing the share of each purchaser by dividing the quantity of emission units requested in their offer to purchase that has not been met by Category A and B reserve emission units by the total of the offers to purchase that have not been met by units in those categories;
(2) by determining the number of Category C emission units to be assigned to each purchaser by multiplying each purchaser’s share by the quantity of emission units available in that category, rounding down to the nearest whole number; and
(3) when Category C emission units remain to be awarded, by assigning a random number to each purchaser and by awarding 1 emission unit per purchaser, in ascending order of the numbers assigned, until all the emission units have been awarded.
