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

Expense Example (USD $)	1 Year	3 Years	5 Years	10 Years
CORE BOND FUND	42	223	419	986

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 its most recent fiscal year, the Predecessor Core Bond Fund’s turnover rate was 851.07% of the average value of its portfolio.

PRINCIPAL INVESTMENT STRATEGIES

The Fund will seek capital appreciation and current income in its attempt to maximize total return. In doing so, the Fund will invest, under normal circumstances, at least 80% of its net assets in bonds and other fixed-income securities. These may include:

• Obligations of the U.S. government or its agencies, instrumentalities or sponsored enterprises, including obligations issued by private issuers that are guaranteed as to principal and interest by the U.S. government, its agencies or instrumentalities;

• Obligations of state, local and foreign governments;

• Obligations of domestic and foreign banks and corporations;

• Zero coupon bonds, debentures, preferred stock and convertible securities;

• Mortgage and other asset-backed securities;

• Stripped securities evidencing ownership of future interest or principal payments on debt obligations; and

• Repurchase agreements relating to the above instruments.

The Fund invests primarily in the investment grade debt obligations of domestic issuers. Investment grade debt obligations are obligations rated within the top four rating categories by a Nationally Recognized Statistical Rating Organization (“NRSRO”) or determined by the Investment Adviser to be of comparable quality. The Fund also may invest to a limited extent in U.S. dollar denominated investment grade obligations of foreign issuers.

In buying and selling securities for the Fund, the investment management team uses a relative value approach. This approach involves an analysis of general economic and market conditions. It also involves the use of models that analyze and compare expected returns and assumed risks. Under the relative value approach, the investment management team will emphasize particular securities and types of securities (such as treasury, agency, asset-backed, mortgage-related and corporate securities) that the team believes will provide a favorable total return in light of these risks.

The Fund’s dollar-weighted average maturity, under normal circumstances, will range between three and fifteen years.

The investment management team may engage in active trading, and will not consider portfolio turnover a limiting factor in making decisions for the Fund.

PRINCIPAL RISKS

MARKET RISK is the risk that the market values of fixed-income securities owned by the Fund may decline, at times sharply and unpredictably.

MANAGEMENT RISK is the risk that a strategy used by the investment management team may fail to produce the intended results.

LIQUIDITY RISK is the risk that certain portfolio securities may be less liquid than others, which may make them difficult or impossible to sell at the time and the price that the Fund would like, adversely affecting the value of the Fund’s investments and its returns.

INTEREST RATE/MATURITY RISK is the risk that the value of the Fund’s assets will decline because of rising interest rates. This risk is generally lower for funds that have shorter-weighted maturities, such as money market funds and short-term bond funds. The magnitude of this decline will often be greater for longer-term fixed-income securities than shorter-term fixed income securities.

PREPAYMENT (OR CALL) RISK is the risk that prepayment of the underlying mortgage or other collateral of some fixed-income securities may result in a decreased rate of return and a decline in value of those securities.

DEBT EXTENSION RISK is the risk that an issuer will exercise its right to pay principal on an obligation held by the Fund (such as a mortgage-backed security) later than expected. This may happen during a period of rising interest rates. Under these circumstances, the value of the obligation will decrease and the Fund will suffer from the inability to invest in higher yielding securities.

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 payment or other financial obligations will adversely affect the value of the Fund’s investments and its returns. Changes in the credit rating of a debt security held by the Fund could have a similar effect.

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.

PORTFOLIO TURNOVER RISK is the risk that high portfolio turnover is likely to lead to increased Fund expenses that may result in lower investment returns. High portfolio turnover also is likely to result in higher short-term capital gains taxable to shareholders. For the last fiscal year, the annual portfolio turnover rate of the Predecessor Core Bond Fund exceeded 100%.

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.

FUND PERFORMANCE

The bar chart and table that follow provide an indication of the risks of investing in the Fund. It is currently contemplated that before the Fund commences operations, substantially all of the assets of the Predecessor Core Bond Fund, another portfolio advised by the Investment Adviser, will be transferred to the Fund in a tax-free reorganization (the “Reorganization”), which is expected to occur on or about November 16, 2012. The Predecessor Core Bond Fund was managed with the same investment objective, strategies and policies as will be followed by the Fund. As a result of the Reorganization, the performance and accounting history of the Predecessor Core Bond Fund prior to the date of the Reorganization will be assumed by the Fund.

The performance information set forth in the bar chart and table below is that of the Class A Shares of the Predecessor Core Bond Fund, which commenced operations on March 29, 2001.

The Predecessor Core Bond Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future.

Updated performance information for the Fund is available and may be obtained on the Fund’s Web site at www.northernfunds.com or by calling 800-595-9111.
