(2)

Northern Trust Investments, Inc. ('NTI' or the 'Investment Adviser') has contractually agreed to reimburse a portion of the operating expenses of the Fund (other than certain excepted expenses, i.e., Acquired Fund Fees and Expenses, the compensation paid to each Independent Trustee of the Trust, expenses of third party consultants engaged by the Board of Trustees, membership dues paid to the Investment Company Institute and Mutual Fund Directors Forum, expenses in connection with the negotiation and renewal of the revolving credit facility, extraordinary expenses and interest) to the extent the 'Total Annual Fund Operating Expenses' exceed 0.85%. This contractual limitation may not be terminated before July 31, 2022 without the approval of the Fund's Board of Trustees.

EXAMPLE

The following Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (taking into account the expense reimbursement arrangement for one year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

PORTFOLIO TURNOVER. The Fund pays transaction costs, such as commissions, when it buys and sells securities (or 'turns over' its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual portfolio operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 91.41% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

In seeking to achieve its investment objective, the Fund will invest, under normal circumstances, at least 80% of its net assets in bonds and other fixed-income securities that are rated below investment grade (commonly referred to as 'junk bonds'). These may include:

Obligations of U.S. and foreign corporations and banks;

Senior and subordinated bonds and debentures;

Zero coupon, pay-in-kind and capital appreciation bonds;

Convertible securities, preferred stock, structured securities; and

Loans and loan participations.

The sub-advisers may shift the Fund's assets among various types of securities based upon changing market conditions, yield differences and the credit-worthiness of issuers among other things.

NF SUM MHYO (7/21) SUMMARY PROSPECTUS 1 MULTI-MANAGER HIGH YIELD OPPORTUNITY FUND

Lower quality securities or below-investment grade securities are rated BB, Ba or lower by a Nationally Recognized Statistical Rating Organization ('NRSRO'), or unrated securities determined to be of comparable quality by one or more of the Fund's sub-advisers. Credit ratings are determined at the time of purchase. There is no minimum rating for a security purchased or held by the Fund, and the Fund may purchase securities that are in default. The Fund does not have any portfolio maturity limitation, and may invest its assets from time to time primarily in instruments with short, medium or long maturities.

Although the Fund primarily invests in the debt obligations of domestic issuers, it may invest in debt obligations of foreign issuers. The Fund's investments in foreign issuers together with notional underlying foreign currency exposure are not expected to exceed 30%.

The Fund may invest up to 15% of its net assets in 'illiquid securities,' i.e. those that the Fund reasonably expects cannot be sold or disposed of in current market conditions within seven calendar days or less without the sale or disposition significantly changing the market value of the investment. The Fund may also invest in securities that are subject to resale restrictions such as those contained in Rule 144A promulgated under the Securities Act of 1933.

The Fund utilizes a 'multi-manager' approach whereby the Fund's assets are allocated to one or more sub-advisers, in percentages determined at the discretion of the Fund's investment adviser. Each sub-adviser acts independently from the others and utilizes its own distinct investment style in selecting securities. However, each sub-adviser must operate within the constraints of the Fund's investment objective, strategies and restrictions.

When determining the allocations and reallocations to sub-advisers, the Fund's investment adviser will consider a variety of factors, including but not limited to the sub-adviser's investment approach, historical performance, and the characteristics of each sub-adviser's allocated assets (including duration, credit quality, average maturity, industry and geographic region). The Fund's investment adviser seeks, through its selection of sub-advisers and its allocation determinations, to reduce portfolio volatility and provide an attractive combination of risk and return for the Fund.

The sub-advisers may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

PRINCIPAL RISKS

As with any investment, you could lose all or part of your investment in the Fund, and the Fund's performance could trail that of other investments. The Fund is subject to certain risks, including the principal risks noted below, any of which may adversely affect the Fund's net asset value ('NAV'), total return and ability to meet its investment objective. Each risk noted below is considered a principal risk of investing in the Fund, regardless of the order in which it appears. The significance of each risk factor below may change over time and you should review each risk factor carefully.

MARKET RISK is the risk that the value of the Fund's investments may increase or decrease in response to expected, real or perceived economic, political or financial events in the U.S. or global markets. The frequency and magnitude of such changes in value cannot be predicted. Certain securities and other investments held by the Fund may experience increased volatility, illiquidity, or other potentially adverse effects in response to changing market conditions, inflation, changes in interest rates, lack of liquidity in the bond or equity markets, volatility in the equity markets, market disruptions caused by local or regional events such as war, acts of terrorism, the spread of infectious illness (including epidemics and pandemics) or other public health issues, recessions or other events or adverse investor sentiment or other political, regulatory, economic and social developments, and developments that impact specific economic sectors, industries or segments of the market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide due to increasingly interconnected global economies and financial markets. Market risk includes the risk that a particular style of investing, such as growth or value, may underperform the market generally.

HIGH-YIELD RISK is the risk that the Fund's below-investment grade fixed-income securities, sometimes known as 'junk bonds,' will be subject to greater credit risk, price volatility and risk of loss than investment grade securities, which can adversely impact the Fund's return and NAV. High yield securities are considered highly speculative and are subject to the increased risk of an issuer's inability to make principal and interest payments.

CREDIT (OR DEFAULT) RISK is the risk that the inability or unwillingness of an issuer or guarantor of a fixed-income security, or a counterparty to a repurchase or other transaction, to meet its principal and interest payments or other financial obligations will adversely affect the value of the Fund's investments and its returns. The credit quality of a debt security or of the issuer of a debt security held by the Fund could deteriorate rapidly, which may impair the Fund's liquidity or cause a deterioration in the Fund's NAV. The Fund could also be delayed or hindered in its enforcement of rights against an issuer, guarantor or counterparty.

RESTRICTED SECURITIES RISK Limitations on the resale of restricted securities may have an adverse effect on their marketability and may prevent the Fund from disposing of them promptly at reasonable prices. There can be no assurance that a trading market will exist at any time for any particular restricted security. Transaction costs may be higher for restricted securities and such securities may be difficult to value and may have significant volatility.

LIQUIDITY RISK is the risk that the Fund will not be able to pay redemption proceeds in a timely manner because of unusual market conditions, an unusually high volume of redemption requests, legal restrictions impairing its ability to sell particular securities or close out derivative positions at an advantageous market price or other reasons. Certain securities may be less liquid than others or may be deemed illiquid in certain instances where a sub-adviser to the Fund may receive material non-public information of a company because one of the sub-adviser's employees, such as a portfolio manager to the Fund, sits on the company's board of directors, which may make them difficult or impossible to sell at the time and the price that the Fund would like and the Fund may have to lower the price, sell other securities instead or forgo an investment opportunity. In addition, less liquid securities may be more

MULTI-MANAGER HIGH YIELD OPPORTUNITY FUND 2 SUMMARY PROSPECTUS

difficult to value and markets may become less liquid when there are fewer interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. For these same reasons, less liquid securities that the Fund may want to invest in may be difficult or impossible to purchase. Banking regulations may also cause certain dealers to reduce their inventories of certain securities, which may further decrease the Fund's ability to buy or sell such securities. All of these risks may increase during periods of market turmoil and could have a negative effect on the Fund's performance.

LOAN RISK Loans may be unrated, less liquid and more difficult to value than traditional debt securities. Loans may be made to finance highly leveraged corporate operations or acquisitions. The highly leveraged capital structure of the borrowers in such transactions may make such loans especially vulnerable to adverse changes in financial, economic or market conditions. Loans generally are subject to restrictions on transfer, and only limited opportunities may exist to sell such loans in secondary markets. As a result, the Fund may be unable to sell loans at a desired time or price. Extended trade settlement periods for certain loans may result in cash not being immediately available to the Fund upon sale of the loan. As a result, the Fund may have to sell other investments with shorter settlement periods or engage in borrowing transactions to raise cash to meet its obligations. Loans are also subject to the risk of price declines and to increases in prevailing interest rates, although the floating rate loans in which the Fund generally invests are substantially less exposed to this risk than fixed-rate debt instruments. If the Fund acquires only an assignment or a participation in a loan made by a third party, the Fund may not be able to control amendments, waivers or the exercise of any remedies that a lender would have under a direct loan and may assume liability as a lender. In addition, loans held by the Fund may not be considered 'securities' under the federal securities laws and therefore the Fund may not receive the same investor protections with respect to such investments that are available to purchasers of investments that are considered 'securities' under the federal securities laws. The Fund may experience relatively greater difficulty or delays in enforcing its rights on its holdings of covenant lite loans than its holdings of loans or securities with financial maintenance covenants, which may result in losses to the Fund, especially during a downturn in the credit cycle.

LOAN PARTICIPATIONS RISK A loan participation agreement involves the purchase of a share of a loan made by a bank to a company in return for a corresponding share of a borrower's principal and interest payments. The principal risk associated with acquiring loan participation interests is the credit risk associated with the underlying corporate borrower. There is also a risk that there may not be a readily available market for loan participation interests and, in some cases, this could result in the Fund disposing of such securities at a substantial discount from face value or holding such securities until maturity.

MULTI-MANAGER RISK is the risk that the sub-advisers' investment styles will not always be complementary or that the investment adviser's allocation of assets amongst sub-advisers will not achieve the intended result, which could negatively impact the performance of the Fund.

MANAGEMENT RISK is the risk that a strategy used by the Fund's investment adviser or sub-advisers may fail to produce the intended results or that imperfections, errors or limitations in the tools and data used by the investment adviser may cause unintended results.

INTEREST RATE RISK is the risk that during periods of rising interest rates, the Fund's yield (and the market value of its securities) will tend to be lower than prevailing market rates; in periods of falling interest rates, the Fund's yield (and the market value of its securities) will tend to be higher. In general, securities with longer maturities or durations are more sensitive to interest rate changes. Risks associated with rising interest rates are heightened given that interest rates in the U.S. are currently at historically low levels. Changing interest rates, including rates that fall below zero, may have unpredictable effects on the markets and the Fund's investments, may result in heightened market volatility, may impact the liquidity of fixed-income securities and of the Fund, and may detract from Fund performance. A low or negative interest rate environment could cause the Fund's earnings to fall below the Fund's expense ratio, resulting in a low or negative yield and a decline in the Fund's share price. A general rise in interest rates may cause investors to move out of fixed income securities on a large scale, which could adversely affect the price and liquidity of fixed income securities and could also result in increased redemptions for the Fund.

VALUATION RISK is the risk that the sale price the Fund could receive for a portfolio security may differ from the Fund's valuation of the security, particularly for securities that trade in low volume or volatile markets or that are valued using a fair value methodology. Fair valuation of the Fund's investments involves subjective judgment. In addition, the value of the securities in the Fund's portfolio may change on days when shareholders will not be able to purchase or sell the Fund's shares.

SOVEREIGN DEBT RISK is the risk that the Fund may invest in securities issued or guaranteed by foreign governmental entities (known as sovereign debt securities). These investments are subject to the risk of payment delays or defaults, due, for example, to cash flow problems, insufficient foreign currency reserves, political considerations, large debt positions relative to the country's economy or failure to implement economic reforms. There is no legal or bankruptcy process for collecting sovereign debt.

ZERO COUPON OR PAY-IN-KIND SECURITIES RISK The value, interest rates, and liquidity of non-cash paying instruments, such as zero coupon and pay-in-kind securities, are subject to greater fluctuation than other types of securities. The higher yields and interest rates on pay-in-kind securities reflect the payment deferral and increased credit risk associated with such instruments and that such investments may represent a higher credit risk than loans that periodically pay interest.

CONVERTIBLE SECURITIES RISK The market values of convertible securities are affected by market interest rates, the risk of actual issuer default on interest or principal payments and the value of the underlying common stock into which the convertible security may be converted. Additionally, a convertible security is subject to the same types of market and issuer risks as apply to the underlying common stock. Certain convertible securities are subject to involuntary conversions and may undergo principal write-downs upon the occurrence of triggering events, and, as a result, are subject to an increased risk of loss. Convertible securities may be rated below investment grade.

SUMMARY PROSPECTUS 3 MULTI-MANAGER HIGH YIELD OPPORTUNITY FUND

PREFERRED SECURITIES RISK Preferred securities are subject to issuer-specific and market risks applicable generally to equity securities. Preferred securities also may be subordinated to bonds or other debt instruments, subjecting them to a greater risk of non-payment, may be less liquid than many other securities, such as common stocks, and generally offer no voting rights with respect to the issuer.

REPURCHASE AGREEMENTS RISK Repurchase agreements involve the risk that the counterparty may default on its obligation to repurchase the underlying instruments collateralizing the repurchase agreement, which may cause the Fund to lose money. This risk is magnified to the extent that a repurchase agreement is secured by securities other than cash or U.S. Government securities.

DEBT EXTENSION RISK is the risk that when interest rates rise an issuer will exercise its right to pay principal on certain debt securities held by the Fund later than expected. This will cause the value of the security, and the Fund's NAV, to decrease, and the Fund may lose opportunities to invest in higher yielding securities.

FOREIGN SECURITIES RISK is the risk that investing in foreign (non-U.S.) securities may result in the Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to less liquid markets, and adverse economic, political, diplomatic, financial, and regulatory factors. Foreign governments may impose limitations on foreigners' ownership of interests in local issuers, restrictions on the ability to repatriate assets, and may also impose taxes. Any of these events could cause the value of the Fund's investments to decline. Foreign banks, agents and securities depositories that hold the Fund's foreign assets may be subject to little or no regulatory oversight over, or independent evaluation, of their operations. Additional costs associated with investments in foreign securities may include higher custodial fees than those applicable to domestic custodial arrangements and transaction costs of foreign currency conversions. Unless the Fund has hedged its foreign currency exposure, foreign securities risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. Currency hedging strategies, if used, are not always successful. For instance, forward foreign currency exchange contracts, if used by the Fund, could reduce performance if there are unanticipated changes in currency exchange rates.

PREPAYMENT (OR CALL) RISK is the risk that an issuer could exercise its right to pay principal on callable debt securities held by the Fund earlier than expected. Issuers may be more likely to prepay when interest rates fall, when credit spreads change, or when an issuer's credit quality improves. If this happens, the Fund will not benefit from the rise in the market price of the securities that normally accompanies a decline in interest rates, and will be forced to reinvest prepayment proceeds in lower yielding securities, which may reduce the Fund's returns. The Fund may also lose any premium it paid to purchase the securities.

STRUCTURED SECURITIES RISK is the risk that structured securities may be more volatile, less liquid and more difficult to price accurately than less complex securities due to their derivative nature. As a result, investments in structured securities may adversely affect the Fund's NAV. In some cases, it is possible that the Fund may suffer a total loss on its investment in a structured security. In addition, the performance and payment of principal and interest of a structured security is tied to that of a reference obligation. Accordingly, risks of structured securities also include those risks associated with the underlying reference obligation including, but not limited to, market risk, interest rate risk, credit risk, default risk and foreign currency risk.

As with any mutual fund, it is possible to lose money on an investment in the Fund. An investment in the Fund is not a deposit of any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation, any other government agency, or The Northern Trust Company, its affiliates, subsidiaries or any other bank.

After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns shown are not relevant to investors who hold their shares through tax-advantaged arrangements, such as 401(k) plans or individual retirement accounts.

In calculating the federal income taxes due on redemptions, capital gains taxes resulting from redemptions are subtracted from the redemption proceeds and the tax benefits from capital losses resulting from the redemptions are added to the redemption proceeds. Under certain circumstances, the addition of the tax benefits from capital losses resulting from redemptions may cause the Returns after taxes on distributions and sale of Fund shares to be greater than the Returns after taxes on distributions or even the Returns before taxes.
