When your financial advisor is providing advice they must adhere to the SEC’s Regulation Best Interest (Reg BI) rule and standard of care. Reg BI replaced the former “suitability” rule and created a ‘best interest’ standard for brokerage firms and registered representatives. This standard applies when a registered representative is providing investment advice through making recommendations customers and covers securities transaction, investment strategies, and recommendations concerning advice on opening of an account or accounts. This standard applies when a registered representative is providing investment advice through making recommendations customers and covers securities transaction, investment strategies, and recommendations concerning advice on opening of an account or accounts.
Another aspect of the care obligation is focusing on the client’s specific needs which brokers must reasonably understand through obtaining information for the client’s investment profile. In completing a customer’s investment profile the advisor should include information such as the investor’s investment time horizon; liquidity needs; risk tolerance; experience with various investment vehicles; investment objectives and financial goals; assets and debts including outside investment accounts; marital status; tax information; age; and other relevant information that may be individual to the investor that the advisor would need to know to properly render advice or provide services. The SEC has stated that Reg BI is drawn from fiduciary principles that are common to both brokers and investment advisors including an obligation to act in the investor’s best interest and prohibiting an advisor from placing their own interests ahead of the investor’s. There are several different aspects of the rule that brokers must comply with. One of which is the care obligations which require brokers to form a reasonable belief that their investment advice and recommendations are in the retail investor’s best interest. The care obligations include three components. First, the advisor must have an understanding of the potential risks, rewards, and costs associated with a product, investment strategy, account type, or series of transactions.
Next, the advisor must have a reasonable understanding of the specific retail investor’s investment profile. The customer’s profile information generally includes an investor’s financial situation and needs; investments; assets and debts; marital status; tax status; age; investment time horizon; liquidity needs; risk tolerance; investment experience; investment objectives and financial goals; and any other information the retail investor may disclose in connection with the recommendation or advice. Finally, the advisor must use their knowledge of the first two elements to consider reasonably available investment option alternatives and come to the conclusion that there is a reasonable basis to believe that the recommendation or advice being provided is in the retail investor’s best interest. Finally, an advisor must also analyze the specific account features offered and determine whether their client can benefit from them in order to meet their care obligations. While securities and investments come with costs that must be considered, the type of securities account also has changes the cost equation for the investor and can change the retail customers’ future investment returns. The associated person must consider the different types of securities accounts for their client and determine whether or not the cost or features are reasonably needed for the client or if the customer’s current account costs and features are superior to solutions available to the advisor. In any event, the type of account and services recommended must be in the investor’s best interest.
