⁽²⁾ Northern Trust Investments, Inc. 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 0.91%. This contractual limitation may not be terminated before July 31, 2021 without the approval of the Fund’s Board of Trustees.

⁽³⁾  The Total Annual Fund Operating Expenses After Expense Reimbursement may be higher than the contractual expense reimbursement rate stated above due to excepted expenses that are not reimbursed.

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 our 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. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

1 Year	3 Years	5 Years	10 Years
$96	$332	$586	$1,315

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 62.47% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

In seeking long-term capital appreciation and current income, the Fund will invest, under normal circumstances, at least 80% of its net assets in equity securities of real estate companies and real estate related companies (collectively “real estate companies”). This means that the Fund will concentrate its investments in companies that derive a significant portion of their revenues from the ownership, construction, financing, management or sale of commercial, industrial or residential real estate or companies that have a significant portion of their assets in these types of real estate-related areas. The Fund will invest in equity-related securities of real estate companies on a global basis, which means that the companies may be U.S. companies or foreign companies. There is no limit on the amount of Fund assets that may be invested in the securities of foreign companies. The Fund anticipates that it will invest greater than 25% of its assets in equity-related securities of real estate companies in the U.S. The Fund does not invest directly in real estate.

NF SUM MGRE (7/20) SUMMARY PROSPECTUS 1 MULTI-MANAGER GLOBAL REAL ESTATE FUND

The Fund anticipates that its investments in equity-related securities of real estate companies will be primarily in securities of companies known as real estate investment trusts (REITs) or U.S. or non-U.S. REIT-like companies that own and/or manage property. The Fund may invest without limit in the securities of REITs. The Fund may also invest in equity securities of other types of real estate companies including REITs that invest in real estate-related loans and real estate operating companies.

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 style, historical performance, and the characteristics of each sub-adviser’s allocated assets (including capitalization, growth and profitability measures, valuation metrics, economic sector exposures, and earnings and volatility statistics). 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 RISKis 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.

REAL ESTATE SECURITIES CONCENTRATION RISK is the risk that investments in securities of real estate companies will make the Fund more susceptible to risks associated with the ownership of real estate and with the real estate industry in general. Real estate companies may have lower trading volumes and may be subject to more abrupt or erratic price movements than the overall securities markets. The value of real estate securities may underperform other sectors of the economy or broader equity markets. To the extent that the Fund concentrates its investments in the real estate sector, it may be subject to greater risk of loss than if it were diversified across different industry sectors.

∎ REIT RISK is the risk that the Fund’s investments will be affected by factors affecting real estate investment trusts (“REITs”) and the real estate sector generally. Investing in REITs involves certain unique risks in addition to those risks associated with investing in the real estate industry in general. These risks include possible declines in the value of real estate, possible lack of mortgage funds and unexpected vacancies of properties. REITs that invest in real estate mortgages are also subject to prepayment risks. REITs whose underlying properties are concentrated in a particular industry or geographic region are also subject to risks affecting such industries and regions. REITs are also subject to heavy cash flow dependency, defaults by borrowers, self-liquidation, interest rate risks (especially mortgage REITs) and liquidity risk. REITs may have limited financial resources, may trade less frequently and in lower volume, engage in dilutive offerings or become more volatile than other securities. By investing in REITs through the Fund, a shareholder will bear expenses of the REITs in addition to expenses of the Fund. In addition, REITs could possibly fail to (i) qualify for favorable tax treatment under applicable tax law, or (ii) maintain their exemptions from registration under the Investment Company Act of 1940.

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 also may impose limits on investment and repatriation and impose taxes. Any of these events could cause the value of the Fund’s investments to decline. To the extent that the Fund’s assets are concentrated in a single country or geographic region, the Fund will be subject to the risks associated with that particular country or region.

∎ CURRENCY RISK is the risk that foreign currencies, securities that trade in or receive revenues in foreign currencies, or derivatives that provide exposure to foreign currencies will fluctuate in value relative to the U.S. dollar, adversely affecting the value of the Fund’s investments and its returns. Because the Fund’s NAV is determined on the basis of U.S. dollars, you may lose money if the local currency of a foreign market depreciates against the U.S. dollar, even if the market value of the Fund’s holdings appreciates. In addition, fluctuations in the exchange values of currencies could affect the economy or particular business operations of companies in a geographic region in which the Fund invests, causing an adverse impact on the Fund’s investments in the affected region.

∎ FOREIGN CUSTODY RISK. The Fund may hold foreign securities and cash with foreign banks, agents, and securities depositories appointed by the Fund’s custodian (each a “Foreign Custodian”). Some Foreign Custodians may be recently organized or new to the foreign custody business. In some countries, Foreign Custodians may be subject to little or no regulatory oversight over or independent evaluation of their operations. Further, the laws of certain countries may place limitations on the Fund’s ability to recover its assets if a Foreign Custodian enters bankruptcy. Investments in emerging markets may be subject to even greater custody risks than investments in more developed markets. Custody services in emerging market countries are very often undeveloped and may be considerably less well-regulated than in more developed countries, and thus may not afford the same level of investor protection as would apply in developed countries.

MULTI-MANAGER RISK is the risk that the sub-advisers’ investment styles will not always be complementary, which could affect 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.

MULTI-MANAGER GLOBAL REAL ESTATE FUND 2 SUMMARY PROSPECTUS

SECTOR RISK is the risk that companies in similar businesses may be similarly affected by particular economic or market events, which may, in certain circumstances, cause the value of securities of all companies in a particular sector of the market to decrease. While the Fund may not concentrate in any one industry, the Fund may invest without limitation in a particular market sector.

GEOGRAPHIC RISK is the risk that if the Fund invests a significant portion of its total assets in certain issuers within the same geographic region, an adverse economic, business or political development affecting that region may affect the value of the Fund’s investments more, and the Fund’s investments may be more volatile, than if its investments were not so concentrated in such geographic.

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. Securities with longer maturities tend to be more sensitive to changes in interest rates, causing them to be more volatile than securities with shorter maturities. Securities with shorter maturities tend to provide lower returns and be less volatile than securities with longer maturities. If interest rates rise, the Fund’s yield may not increase proportionately, and the maturities of income securities that have the ability to be prepaid or called by the issuer may be extended. Changing interest rates may have unpredictable effects on the markets and the Fund’s investments. Recent and any future declines in interest rate levels could cause the Fund’s earnings to fall below the Fund’s expense ratio, resulting in 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. A low or declining interest rate environment poses additional risks to the Fund’s performance, including the risk that proceeds from prepaid or maturing instruments may have to be reinvested at a lower interest rate. Fluctuations in interest rates may also affect the liquidity of fixed income securities and instruments held by the Fund.

CYBERSECURITY RISK is the risk of an unauthorized breach and access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, or the risk of an incident occurring that causes the Fund, the investment adviser, sub-advisers, custodian, transfer agent, distributor and other service providers and financial intermediaries to suffer data breaches, data corruption or lose operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The Fund and its investment adviser have limited ability to prevent or mitigate cybersecurity incidents affecting third-party service providers, and such third-party service providers may have limited indemnification obligations to the Fund or its investment adviser. Successful cyber-attacks or other cyber-failures or events affecting the Fund or its service providers may adversely impact and cause financial losses to the Fund or its shareholders. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cyber-attacks or other cyber-failures.

INITIAL PUBLIC OFFERING (“IPO”) RISK is the risk that the market value of shares in an IPO will fluctuate considerably or decline shortly after the IPO, due to factors such as the absence of a prior public market, unseasoned trading, the small number of shares available for trading and limited information about the issuer.

LARGE SHAREHOLDER RISK is the risk that the Fund may experience adverse effects when certain large shareholders, including funds or accounts over which the Fund’s investment adviser or an affiliate of the investment adviser has investment discretion, purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions, which may occur rapidly and unexpectedly, may cause the Fund to sell its securities at times it would not otherwise do so, which may negatively impact its liquidity and/or NAV. Such sales may also accelerate the realization of taxable income to shareholders if these sales result in gains, and may also increase transaction costs. In addition, large redemptions could lead to an increase in the Fund’s expense ratio due to expenses being allocated over a smaller asset base. Large purchases of the Fund’s shares may also adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash or otherwise maintains a larger cash position than it ordinarily would.

MID CAP STOCK RISK is the risk that stocks of mid-sized companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Mid-sized companies may have limited product lines or financial resources, and may be dependent upon a particular niche of the market.

SMALL CAP STOCK RISK is the risk that stocks of smaller companies may be subject to more abrupt or erratic market movements than stocks of larger, more established companies. Small companies may have limited product lines or financial resources, or may be dependent upon a small or inexperienced management group, and their securities may trade less frequently and in lower volume than the securities of larger companies, which could lead to higher transaction costs. Generally, the smaller the company size, the greater the risk.

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. The Fund’s ability to value its investments may be impacted by technological issues and/or errors by pricing services or other third-party service providers. 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.

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-deferred 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.
