8 For each metric, a Relative Score is assigned: 10 points are awarded to the most competitive bid, 0 points are awarded to the least competitive bid, and all bids in between earn a pro-rated number of points based on the difference between the best and worst bid. The Total Relative Score is calculated as the weighted average of all Relative Scores in accordance with the following weightings: Spread Goal % Time at NBBO Top of Book Size Tier A Securities 10% 50% 40% Tier B Securities 50% 25% 25% Example: Scoring for a Tier A Security Biddable Metrics Relative Score & Weights Broker Spread Goal Top of Book Size % Time at NBBO Spread Goal 10% Top of Book Size 40% % Time at NBBO 50% Total Relative Score A 0.05 13,000 90% 10.00 10.00 8.33 9.17 B 0.05 5,000 90% 10.00 0.00 8.33 5.17 C 0.06 8,000 92% 5.00 3.75 10.00 7.00 D 0.07 7,000 80% 0.00 2.50 0.00 1.00 b. If there is a tie between 2 bids, then the assignments are awarded to the 2 firms involved in the tie. c. If there is a tie among more than 2 bids, the 2 firms with the lowest percentage of underperforming securities in the previous 12 months (the “lead bidders”) that are better than all other firms involved in the tie by 10% or more are awarded the assignment. For greater certainty, if the lead bidders are not better than any other firm by 10% or more, all firms within such 10% threshold are considered to be in a tie with the lead bidders, and in such instance Subsection 2.7.1(3)d below applies. Net new Market Makers having less than one year of history in the Program by default fall in the 50th percentile of underperformance. TSX may adjust the 10% threshold with advance notice. d. If there is still a tie among multiple bids, TSX applies its discretion to award the security assignment. Other factors taken in consideration may include, but are not limited to: • a Market Maker’s market making experience; • the issuer’s recommendation; • the strategic focus of the Market Maker; • the desirability of maintaining a long-run balance, depth and breadth of Market Makers; and • other factors which are likely to contribute to a Market Maker’s ability to compete with other liquidity providers, such as the Market Maker’s technological capability, market presence, global reach, and lines of business. 4.
