| (1) | Northern Trust Investments, Inc. (“NTI”) has contractually agreed to reimburse a portion of the operating expenses of the Fund so that after such reimbursement the Total Annual Fund Operating Expenses of the Fund (excluding (i) acquired fund fees and expenses; (ii) the compensation paid to each Independent Trustee of the Trust; (iii) expenses of third party consultants engaged by the Board of Trustees; (iv) membership dues paid to the Investment Company Institute and Mutual Fund Directors Forum; (v) expenses in connection with the negotiation and renewal of the revolving credit facility; and (vi) extraordinary expenses and interest) do not exceed 0.45%.

These contractual limitations may not be terminated before July 31, 2027 without the approval of the 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 fund operating expenses or in the Example, affect the Fund’s performance. During the most recent fiscal year, the Fund’s portfolio turnover rate was 43.13% of the average value of its portfolio.
PRINCIPAL INVESTMENT STRATEGIES
In seeking its investment objective, the Fund will invest, under normal circumstances, at least 80% of its net assets in a broadly diversified portfolio of equity securities of large capitalization U.S. companies, including foreign issuers that are traded in the U.S. Large capitalization companies generally are considered to be those whose market capitalization is within the range of the market capitalization of the companies in the Russell 1000® Index.
The Fund seeks to achieve its investment objective by employing a strategy that uses statistics and advanced econometric methods to evaluate fundamental and quantifiable stock or firm characteristics (such as relative valuation, price momentum and earnings quality). The characteristics are combined to create a proprietary multifactor quantitative stock selection model, which generates stock specific forecasts that are used along with controls intended to manage risk to determine security weightings. Under the Fund’s core investment style, the Fund invests in a mix of both growth and value securities and the Fund’s overall portfolio is not anticipated to show a significant bias to either style.
The Fund may use derivatives such as stock index futures contracts to equitize cash and enhance portfolio liquidity. Derivatives instruments that provide investment exposure to investments in the Fund’s 80% investment policy and derivatives instruments that provide investment exposure to one or more of the market risk factors associated with such
| NF SUM NOLCX (7/26) | SUMMARY PROSPECTUS | 1 | LARGE CAP CORE FUND |
securities may be counted towards the Fund’s 80% investment policy. NTI will normally sell a security that it believes is no longer attractive based upon the evaluation criteria described above.
From time to time the Fund may have a focused investment (i.e., investment exposure comprising more than 15% of its total assets) in one or more particular sectors. As of March 31, 2026, the Fund had a focused investment in the information technology sector.
Frank Russell Company does not endorse any of the securities in the Russell 1000® Index. It is not a sponsor of the Large Cap Core Fund and is not affiliated with the Fund in any way.
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, elevated levels of government debt, changes in interest rates, lack of liquidity in the bond or equity markets or volatility in the equity markets. Market disruptions caused by local or regional events such as financial institution failures, changes in trade regulation or economic sanctions, internal unrest and discord, war, acts of terrorism, the spread of infectious illness (including epidemics and pandemics) or other public health issues, recessions, the threat or occurrence of a government shutdown, or other events or adverse investor sentiment could have a significant impact on the Fund and its investments. During periods of market disruption or other abnormal market conditions, the Fund’s exposure to risks described elsewhere in this summary will likely increase.
INVESTMENT STYLE RISK is the risk that different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor, depending on market and economic conditions as well as investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ a different investment style. The Fund may also employ a combination of styles that impacts its risk characteristics.
| ∎ | QUANTITATIVE INVESTING RISK is the risk that the value of securities or other investments selected using quantitative analysis can perform differently from the market as a whole or from their expected performance and the Fund may realize a loss. This may be as a result of the factors used in building a multifactor quantitative model, the weights placed on each factor, the accuracy of historical data utilized, and changing sources of market returns. Whenever a model is used, there is also a risk that the model will not work as planned. |
MANAGEMENT RISK is the risk that a strategy used by the Fund’s investment adviser 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.
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.
| ∎ | INFORMATION TECHNOLOGY SECTOR RISK is the risk that securities of technology companies may be subject to greater price volatility than securities of companies in other sectors. These securities may fall in and out of favor with investors rapidly, which may cause sudden selling and dramatically lower market prices. Technology companies also may be affected adversely by changes in technology, consumer and business purchasing patterns, government scrutiny or regulation, legal action and/or obsolete products or services. |
DEPOSITARY RECEIPTS RISK Foreign securities may trade in the form of depositary receipts. In addition to investment risks associated with the underlying issuer, depositary receipts may expose the Fund to additional risks associated with non-uniform terms that apply to depositary receipt programs, including credit exposure to the depository bank and to the sponsors and other parties with whom the depository bank establishes the programs, currency, political, economic, market risks and the risks of an illiquid market for depositary receipts. Depositary receipts are generally subject to the same risks as the foreign securities that they evidence or into which they may be converted. Depositary receipts may not track the price of the underlying foreign securities on which they are based, may have limited voting rights, and may have a distribution subject to a fee charged by the depository. As a result, equity shares of the underlying issuer may trade at a discount or premium to the market price of the depositary receipts.
DERIVATIVES RISK is the risk that derivatives may pose risks in addition to and greater than those associated with investing directly in securities, currencies and other instruments, may be illiquid or less liquid, more volatile, more difficult to value and leveraged so that small changes in the value of the underlying instrument may produce disproportionate losses to the Fund. Derivatives are also subject to counterparty risk, which is the risk that the other party to the transaction will not perform its contractual obligations. The use of derivatives is a highly specialized activity that involves investment techniques and risks different from those associated with investments in more traditional securities and instruments.
| ∎ | FUTURES CONTRACTS RISK is the risk that there will be imperfect correlation between the change in market value of the Fund’s securities and the price of futures contracts, which may result in the strategy not working as intended; the possible inability of the Fund to sell or close out a futures contract at the desired time or price; losses due to unanticipated market movements, which potentially are unlimited; and the possible inability of the Fund’s investment adviser to correctly predict the direction of |
| LARGE CAP CORE FUND | 2 | SUMMARY PROSPECTUS |
| securities’ prices, interest rates, currency exchange rates and other economic factors, which may make the Fund’s returns more volatile or increase the risk of loss. |
SECURITIES LENDING RISK is the risk that the Fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. The Fund could also lose money in the event of a decline in the value of collateral provided for loaned securities or a decline in the value of any investments made with cash collateral.
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.
