UMIR section 1.1 – “hearing”, “Hearing Panel” and “Market Regulator”
Regulatory History:
In connection with the recognition of IIROC and its adoption of UMIR, the applicable securities commissions approved an amendment to repeal and replace Rule 10.6 that came into force June 1, 2006. See Footnote 1 of Status of Amendments. Prior to that date, Rule 10.6 read as follows:
Effective September 1, 2016, the applicable securities commissions approved an amendment to repeal Rule 10.6 of UMIR as it will be replaced by consolidated rules 8203 and 8205. See IIROC Notice 16-0122 – “Implementation of the consolidated IIROC Enforcement, Examination and Approval Rules” (June 9, 2016).
Rule 8.1 governs client-principal trades. It provides that, for trades of 50 standard trading units or less, a Participant trading with one of its clients as principal must give the client a better price than the client could obtain on a marketplace. A Participant must take reasonable steps to ensure that the price is the best available price for the client taking into account the condition of the market. If the security is traded on more than one marketplace, the client must receive, when the Participant is buying, a higher price than the best bid price, and, if the Participant is selling, the client must pay a lower price than the best ask price.
For client-principal trades greater than 50 standard trading units, the Participant may do the trade provided the client could not obtain a better price on a marketplace in accordance with its best execution obligation under Part C of Corporation Rule 3100 – Best Execution of Client Orders. The Participant must take reasonable steps to ensure that the best price is obtained and the price to the client is justified by the condition of the market.
A Participant owes a fiduciary duty to its clients. This duty and investors’ trust in our Participants are fundamental to investor confidence in the integrity of the market. In the Market Regulator’s view, this relationship of trust arises where there is reliance by the client on the Participant’s expertise in securities matters. From the point of view of both the client and the Participant, the fiduciary responsibility exists regardless of the legal form of the transaction. In other words, an investor who relies on the expertise of a Participant expects the Participant to act in the investor's best interests regardless of whether the Participant is acting as agent or as principal. The legal framework underpinning client-principal trades was stated in the 1965 report of the Royal Commission on the Windfall Co. scandal:
An agent must conduct himself so that the interest of the person in whose behalf he is acting is not brought into conflict with his personal interest. An agent may not make for himself any deal which could have been made for his client within the scope of the client’s instructions; if he does, he is assumed to have been acting on his client’s behalf and the client is entitled to the benefit of the transaction. An agent must disclose to the client any fact known to the agent which would be likely to operate on the client’s judgment. An agent may not, in connection with his client’s business, make a secret profit for himself.
These restrictions flow from the recognition of the serious conflicts inseparable from the agency relationship, and from a corresponding recognition that every such conflict must be resolved in favour of the client. A principal trade may be subject to attack if it appears that the Participant did not act to the best advantage of its client even if the Participant complies with the technical requirements of the Rule. For example, if the principal account profited from the trade by unwinding the position again soon after the principal trade was made, or if the Registered Representative receives a higher commission than for agency transactions of a similar size involving similar securities, the Participant will find it more difficult to justify its actions. Participants should obtain their own legal advice as to the propriety of their client-principal trading practices. The following are considerations in any client-principal trade:
Consent — At common law, the prior informed consent of the client must be obtained before the agent may act as principal. This is impractical in the context of trading securities on a marketplace, where at the time of receipt of the client's order the Participant will likely not know who will be on the other side. If the Participant, through the Registered Representative or other employee knows that the firm or a non-client of the firm will or probably will take the other side, the client's consent should be obtained. In particular, if the Registered Representative wishes to take the other side of the trade with their client, the client must be informed and consent to the trade in advance. Such consent must be specific to that trade and cannot be in a general consent to any future trades with the Registered Representative. As promptly as possible following the execution of a principal trade, the client should be advised that all or part of the securities taken or supplied were from an account in which the Participant or a non-client of the Participant has an interest. This advice would form part of the usual discussion that occurs when a Registered Representative confirms to the client that the client’s order has been filled. In addition, the written confirmation must disclose that the order has been filled in a principal transaction.
Nature of the Client — Some clients are in greater need of protection from the potential conflict of interest in client-principal trades. The onus on the Participant usually will be reduced if the client is a fully informed institutional client with regard to the state of the market. Sophisticated institutional clients are able to judge whether a specific net price is appropriate in the context of the market. If there was no prior discussion with the client concerning executing the client's order in a client-principal trade, or if there are no standing instructions on handling of orders, the Participant must judge whether any steps need be taken, taking into account the size of the order and other circumstances, to ensure that a better price is not available. To a large degree this will depend on the depth of the market and normal liquidity of the security.
Suitability — Compliance with the client-principal trading rules does not relieve a Participant of its suitability and "know your client" obligations. As with any other trade, Participants must ensure that the trade is suitable for the client, even if the best possible price has been obtained.
Facilitation Accounts — The rules do not apply to a client-principal trade where the inventory account was used solely to facilitate the execution or confirmation of a client order (for example, an inventory accumulation account used to give an institutional client a single average-price confirmation). In these cases, the client is the beneficial owner of the position in the inventory account at all times.
Refusal by Client — Participants should ensure that procedures are in place to identify orders that should not be effected on a principal basis. This is necessary to deal with situations where clients notify a Participant that they do not consent to principal trading generally or to particular principal trades.
The price of the principal transaction must also be justified by prevailing market conditions. Participants should consider such factors as:
For example, if the market is $10 bid and $10.50 asked and a client wants to sell 1,000 shares, it would be inappropriate for a Participant to do a principal trade at $10.05 if the security has been trading heavily at $10.50 and there is strong bidding for the security at $10 compared to the number of securities being offered at $10.50. The condition of the market suggests that the client should be able to sell at a better price than $10.05. Accordingly, the Participant as agent for the client should post an offer at $10.45 or even $10.50, depending on the circumstances. The desire of the client to obtain a fill quickly is always a consideration.
Of course, if a client expressly consents to a principal trade on a fully-informed basis, following the client’s instructions will be reasonable.
In determining the “best available price”, Participants should consider the price and size of orders displayed on marketplaces other than protected marketplaces if such information is available or known to the Participant. Specifically, we expect an employee of a Participant to use all order price information that is available or known to that employee when determining the “best available price”. For example, an employee that has access to price information from both protected and unprotected marketplaces would be in compliance with the requirement to determine the “best available price” only if all price information from both protected and unprotected marketplaces was considered when executing a principal order or non-client order with a client order. However, a Participant will be considered not to have complied with Rule 8.1 if an employee executes a principal order or non-client order with a client order at a better price which is inferior to the price that would have been available to the client on a displayed marketplace that is not a protected marketplace and the employee executes, in whole or in part, with the order displayed on the marketplace that is not a protected marketplace.
