Summary Prospectus by Investment Company (Form 497K)

●

Equity Securities. The value of equity securities will rise and fall in response to the activities of the company that issued them, general market conditions and/or economic conditions. Investments in medium capitalization companies may involve greater risks because these companies generally have narrower markets, more limited managerial and financial resources and a less diversified product offering than larger, more established companies. Some medium capitalization stocks may also be thinly traded, and thus, difficult to buy and sell in the market.

●

Global Financial Markets Risk. Global financial markets are increasingly interconnected and conditions (including volatility and instability) and events (including natural disasters, pandemics and epidemics) in one country, region

●

Liquidity Risk. The market for certain investments may become illiquid or less liquid (i.e., there may be a significant reduction in trading activity, including in the number of market participants or transactions, in such investments) under adverse or volatile market or economic conditions, making those investments difficult to sell. The market price of certain investments may fall dramatically if there is no liquid trading market. For derivatives, this also includes the risk involving liquidity demands that derivatives can create to make payments of margin or settlement payments to counterparties. Such events and conditions may adversely affect the value of the Fund's investments, result in greater market or liquidity risk or cause difficulty valuing the Fund's portfolio instruments or achieving the Fund's objective.

●

Active Management. Despite strategies designed to achieve the Fund's investment objective, the value of investments will change with market conditions, and so will the value of any investment in the Fund and you could lose money. The securities selected for the portfolio may not perform as RIM or the Fund's money managers expect. Additionally, securities selected may cause the Fund to underperform relative to other funds with similar investment objectives and strategies. There is no guarantee that RIM will effectively assess the Fund's portfolio characteristics and it is possible that its judgments regarding the Fund's exposures may prove incorrect. In addition, actions taken to manage Fund exposures, including risk, may be ineffective and/or cause the Fund to underperform.

●

Short Sales Risk. A short sale will result in a loss if the price of the security sold short increases between the date of the short sale and the date on which the borrowed security must be returned. Short sales may give rise to a form of leverage. Leverage tends to exaggerate the effect of any increase or decrease in the value of portfolio securities. Short sales have the potential for unlimited loss.

●

Multi-Manager Approach. While the investment styles employed by the money managers are intended to be complementary, they may not in fact be complementary. A multi-manager approach could result in more exposure to certain types of securities and higher portfolio turnover.

●

Fundamental Investing Risk. A fundamental investment approach uses research and analysis of a variety of factors to create a forecast of company results, which is used to select securities. The process may result in an evaluation of a security's value that may be incorrect or, if correct, may not be reflected by the market. Security or instrument selection using a fundamental investment approach may also cause the Fund to underperform other funds with similar investment objectives and investment strategies even in a rising market.

●

Quantitative Investing and Models. Quantitative inputs and models use historical company, economic and/or industry data to evaluate prospective investments or to generate forecasts which could result in incorrect assessments of the specific portfolio characteristics or ineffective adjustments to the Fund's exposures. Securities selected using quantitative analysis may perform differently than analysis of their historical trends would suggest. Inputs or models may be flawed or not work as anticipated and may cause the Fund to underperform other funds with similar investment objectives and strategies.

●

Derivatives. Investments in a derivative instrument could lose more than the initial amount invested. Compared to conventional securities, derivatives can be more sensitive to changes in interest rates or to sudden fluctuations in market prices and thus the Fund's losses may be greater if it invests in derivatives than if it invests only in conventional securities. The use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in equity or fixed income securities, currencies or other instruments. Derivatives are generally subject to a number of risks such as leveraging risk, liquidity risk, market risk, credit risk, default risk, counterparty risk (the risk that the other party in an agreement will fail to perform its obligations), management risk, operational risk and legal risk. Certain of these risks do not apply to derivative instruments entered into for hedging or cash equitization, certain cleared derivative instruments, and written options contracts. Derivatives also involve the risk of mispricing or improper valuation and the risk that changes in the value of the derivative instrument may not correlate exactly with the change in the value of the underlying asset, rate or index.

●

Index-Based Investing. Index-based strategies (including index replication which seeks to purchase the securities in an index or a blend of indexes and optimized index sampling which seeks to purchase a sampling of securities using optimization and risk models), which may be used to gain desired Fund exposures, may cause the Fund's returns to be lower than if the Fund employed a fundamental investment approach to security selection with respect to that portion of its portfolio. Additionally, index-based strategies are subject to "tracking error" risk, which is the risk that the performance of the portion of the Fund's portfolio utilizing an index-based strategy will differ from the performance of the index it seeks to track.

●

Depositary Receipts. Depositary receipts (including American Depositary Receipts and Global Depositary Receipts) are securities traded on a local stock exchange that represent securities issued by a foreign publicly-listed company. Depositary receipts are generally subject to the same risks of investing in the foreign securities they evidence or into which they may be converted.

●

Information Technology Sector Risk. To the extent that the Fund invests significantly in the information technology sector, the Fund will be sensitive to changes in, and the Fund's performance may depend to a greater extent on, the overall condition of the information technology sector. Companies in the information technology sector can be significantly affected by short product cycles, obsolescence of existing technology, impairment or loss of intellectual property rights, falling prices and profits, competition from new market entrants, government regulation and other factors.

●

Real Estate Investment Trusts ("REITs"). REITs may be affected by changes in the value of the underlying properties owned by the REITs and by the quality of tenants' credit.

●

Counterparty Risk. Counterparty risk is the risk that the other party or parties to an agreement or a participant to a transaction, such as a broker, might default on a contract or fail to perform by failing to pay amounts due or failing to fulfill the obligations of the contract or transaction.

●

Non-Discretionary Implementation Risk. With respect to the portion of the Fund that is managed pursuant to model portfolios provided by non-discretionary money managers, it is expected that trades will be effected on a periodic basis and therefore less frequently than would typically be the case if discretionary money managers were employed. Given that values of investments change with market conditions, this could cause the Fund's return to be lower than if the Fund employed discretionary money managers with respect to that portion of its portfolio.

●

Impact of Large Redemptions (Including Possible Fund Liquidation). The Fund may be used as an investment by certain funds of funds and in asset allocation programs and may have a large percentage of its Shares owned by such funds or held in such programs. Large redemption activity could result in the Fund incurring additional costs and being forced to sell portfolio securities at a loss to meet redemptions. Large redemptions may also result in increased expense ratios, higher levels of realized capital gains or losses with respect to the Fund's portfolio securities, higher Fund cash levels, higher brokerage commissions and other transaction costs, among other negative consequences such as reduced liquidity in the Fund's portfolio. As a result, large redemption activity could adversely affect the Fund's ability to conduct its investment program which, in turn, could adversely impact the Fund's performance or may result in the Fund no longer remaining at an economically viable size, in which case the Fund may cease operations.

●

Cyber Security and Other Operational Risks. An investment in the Fund, like any fund, can involve operational risks. In addition, other disruptive events may adversely affect the Fund's ability to conduct business. While the Fund seeks to minimize such risks and events through controls and oversight, including business continuity plans and risk management systems, there may still be events or failures that could cause losses to the Fund. In addition, the Fund may be susceptible to operational risks through breaches in cyber security. A cyber security breach may cause sensitive information (including relating to personally identifiable information of investors) to be lost, improperly accessed, used or disclosed. The Fund and its shareholders could be negatively impacted by such disruptive events or cyber security incidents.
