BMO Target Retirement 2050 Fund

BMO Target Retirement 2050 Fund

Investment Objective:

To achieve growth, income, and conservation of capital to varying degrees depending on its proximity to its target date. As the Fund approaches and passes its target date, the Fund will reduce its emphasis on growth and increase its emphasis on income and preservation of capital.

Example

This example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example assumes that you invest $10,000 in the Fund for the time periods indicated, whether you redeem all of your shares at the end of those periods or not. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses are as shown in the table and remain the same. The costs in the one-year example and for the first year of the three-, five-, and ten-year examples reflect the Adviser’s agreement to waive fees and reimburse expenses through December 31, 2019. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

Expense Example - BMO Target Retirement 2050 Fund - USD ($)	Class Y	Class R3	Class R6
1 Year	$ 100	$ 125	$ 59
3 Years	395	473	270
5 Years	713	845	498
10 Years	$ 1,612	$ 1,889	$ 1,154

Expense Example, No Redemption - BMO Target Retirement 2050 Fund - USD ($)	Class Y	Class R3	Class R6
1 Year	$ 100	$ 125	$ 59
3 Years	395	473	270
5 Years	713	845	498
10 Years	$ 1,612	$ 1,889	$ 1,154

Portfolio Turnover

The Fund incurs 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 27% of the average value of its portfolio.

Principal Investment Strategies

The Fund will attempt to achieve its investment objectives by investing primarily in other BMO mutual funds representing a variety of asset classes (the underlying funds) according to an asset allocation strategy developed by the Adviser. The Adviser may add unaffiliated funds to the underlying funds in its discretion and periodically may rebalance or modify the asset mix and change the underlying funds.

The Fund is designed for an investor who expects to retire in or around the year 2050 (the target date) at age 67 and who plans to withdraw the value of the investor’s account in the Fund gradually after retirement. The target date is the year that an investor likely would stop making new investments in the Fund.

The Fund may invest up to 100% of its total assets in funds that invest principally in equity securities. Equity securities in which the underlying funds may invest may be of any market capitalization and include common stock, preferred stock, depositary receipts, rights and warrants, and exchange-traded funds. The Fund also may invest in underlying funds that invest principally in fixed income securities. Fixed income securities in which the underlying funds may invest may be of any quality or maturity and include corporate bonds, government securities, mortgage-backed and asset-backed securities, and convertible securities (fixed income securities convertible into shares of common or preferred stock). The Fund also may invest in underlying funds that invest principally in alternative investments to manage volatility of the portfolio. Alternative investments in which the underlying funds may invest include REITs, commodity-linked derivatives, and funds that use alternative investment strategies, which may include investments in derivative instruments. In addition, the Fund may invest in underlying funds that invest in cash, cash equivalents, and other short-term fixed income instruments, including money market funds. While the Fund will invest primarily in underlying funds that invest in U.S. securities, some underlying funds may invest in foreign securities, including emerging markets.

The allocation to asset classes and funds is expected to change over time, becoming more conservative as time elapses. This change is referred to as the “glide path” to the retirement date. The decline in the equity allocation is necessary to reduce market risk and portfolio volatility approaching and into retirement. The Fund does not guarantee a level of income during retirement. It is intended to serve as a post-retirement investment portfolio to provide an income stream made up of regular withdrawals throughout retirement, as well as some growth to offset the effects of inflation. The following chart reflects the Adviser’s general approach to making the portfolio more conservative over time and is for illustrative purposes only.


The Fund’s exposure to funds that invest principally in equity securities will continue to decline for as long as 15 years after its target date, when its allocation to funds that invest principally in equity securities will remain fixed at approximately 26% of its total assets with the remaining allocation devoted to funds that invest principally in fixed income securities, alternative investments, and money market instruments. The Fund’s exposure to funds that invest principally in alternative investments is expected to be approximately 5% of its total assets, increasing over time and remaining fixed at approximately 10% of total assets on and after the target date.

The allocations shown in the glide path represent target allocations, but they do not reflect any tactical decisions made by the Adviser to overweight or underweight a particular asset class or sector based on its market expectations. The target allocations assigned to the broad asset classes (equities and fixed income) are based upon the current market outlook.

The Adviser will continuously monitor the Fund and may make modifications to either the investment approach or the underlying fund allocations that the Adviser believes could benefit shareholders. Any change to existing target allocations or from tactical adjustments around the target allocations are not expected to vary from the existing target allocations set forth in the glide path generally by more than plus or minus five percentage points.

Although the Fund intends to invest primarily in a combination of underlying funds, the Fund may invest directly in equity, fixed income securities, certain alternative investments, and money market securities.

For temporary defensive purposes during unusual economic or market conditions or for liquidity purposes, the Fund may invest up to 100% of its assets directly in cash, money market funds, and other money market instruments, repurchase agreements, and other short-term obligations. When the Fund engages in such activities, it may not achieve its investment objective.

Principal Risks

The Fund cannot assure that it will achieve its investment objective. An investment in the Fund is not a deposit of BMO Harris Bank N.A., or any of its affiliates, and is not insured or guaranteed by the FDIC or any other government agency. There are risks associated with investments in target date funds, and there is no guarantee that the Fund will provide adequate income at and through a shareholder’s retirement.

This section describes the principal risks associated with the Fund’s principal investment strategies. The net asset value of the Fund will vary, and you could lose money by investing in the Fund. The likelihood of loss may be greater if you invest for a shorter period of time. Investors in the Fund should have a long-term perspective and be able to tolerate potentially sharp declines in value.

Affiliated Fund Risk. The Adviser’s authority to select and substitute underlying funds from a variety of affiliated and unaffiliated mutual funds may create a conflict of interest because the Adviser and its affiliated companies typically receive fees from the affiliated funds.

Asset Allocation Risk. Investments in the Fund are subject to risks related to the Adviser’s allocation choices. The selection of the underlying funds and the allocation of the Fund’s assets among the various asset classes and market segments could cause the Fund to lose value or cause the Fund to underperform relevant benchmarks or other funds with similar investment objectives.

Cybersecurity Risk. With the increased use of technologies such as the Internet to conduct business, the Fund is susceptible to operational, information security, and related risks. Cyber incidents affecting the Fund or its service providers have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, interference with the Fund’s ability to calculate its net asset value, impediments to trading, the inability of shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, or additional compliance costs.

Market Risk. Stock and bond markets rise and fall daily. As with any investment whose performance is tied to these markets, the value of your investment in the Fund will fluctuate, which means that you could lose money.

Underlying Fund Investment Risk. The Fund invests in underlying funds and incurs expenses related to the underlying funds. In addition, investors in the Fund will incur fees to pay for certain expenses related to the operations of the Fund. An investor holding the underlying funds directly and in the same proportions as the Fund would incur lower overall expenses, but would not receive the benefit of the portfolio management and other services provided by the Fund. The Fund’s risks are directly related to the risks of the underlying funds. It is important to understand the risks associated with investing in the underlying funds.

• Asset-Backed/Mortgage-Backed Securities Risk. Asset-backed and mortgage-backed securities are subject to risks of prepayment. An underlying fund’s yield will be reduced if cash from prepaid securities is reinvested in securities with lower interest rates. The risk of prepayment also may decrease the value of mortgage-backed securities. Asset-backed securities may have a higher level of default and recovery risk than mortgage-backed securities. Both of these types of securities may decline in value because of mortgage foreclosures or defaults on the underlying obligations. Credit risk is greater for mortgage-backed and asset-backed securities that are subordinate to another security.

• Derivatives Risk. The performance of derivative instruments depends largely on the performance of the underlying reference instrument and the portfolio manager’s ability to predict correctly the direction of securities prices, interest rates, currency exchange rates, and/or other economic factors. Derivatives involve additional costs and can create economic leverage in an underlying fund’s portfolio which may result in significant volatility and cause the underlying fund to participate in losses (as well as gains) in an amount that exceeds the underlying fund’s initial investment. Other risks include liquidity due to possible lack of a secondary market, mispricing or improper valuation of the derivative instrument, and imperfect correlation between the value of the derivative and the underlying instrument so that the underlying fund may not realize the intended benefits. When used for hedging, the change in value of the derivative also may not correlate specifically with the currency, security or other risk being hedged. With over-the-counter derivatives, there is the risk that the other party to the transaction will fail to perform. Specific types of derivative securities also are subject to a number of additional risks, such as:

  Forward Foreign Currency Exchange Contracts Risk. Forward foreign currency exchange contracts are subject to currency risks. A forward foreign currency exchange contract also may result in losses in the event of a default or bankruptcy of the counterparty. Forward foreign currency exchange contracts may limit potential gain from a positive change in the relationship between the U.S. dollar and foreign currencies.
  
  Forward Contracts Risk. Forward contracts are not currently exchange-traded and therefore no clearinghouse or exchange stands ready to meet the obligations of the contracts. Thus, an underlying fund faces the risk that its counterparties may not perform their obligations. Non-deliverable forwards are considered swaps and may in the future be required to be centrally cleared and traded on public facilities.
  
  Options and Futures Risk. Options and futures contracts may be more volatile than investments directly in the underlying securities, involve additional costs, and may involve a small initial investment relative to the risk assumed.
  
  Swap Agreements Risk. A swap agreement may not be assigned without the consent of the counterparty and may result in losses in the event of a default or bankruptcy of the counterparty.

• Emerging Markets Risk. Investments in emerging markets can involve risks in addition to and greater than those generally associated with investing in more developed foreign markets, which may make emerging market securities more volatile and potentially less liquid than securities issued in more developed markets.

• Equity Risk. The prices of equity securities rise and fall daily. These price movements may result from factors affecting individual companies, industries, or the securities market as a whole. In addition, equity markets tend to move in cycles, which may cause stock prices to fall over short or extended periods of time.

• Fixed Income Risk. Interest rates rise and fall over time, which will affect an underlying fund’s yield and share price. The credit quality of a portfolio investment could also cause an underlying fund’s share price to fall. An underlying fund could lose money if the issuer or counterparty defaults by failing to pay interest or principal when due. Fixed income securities may be paid off earlier or later than expected. Either situation could cause an underlying fund to hold securities paying lower-than-market rates of interest, which could hurt the fund’s yield or share price.

• Foreign Securities Risk. Investing in foreign securities may involve additional risks, including currency-rate fluctuations, political and economic instability, differences in financial reporting standards, less-strict regulation of the securities markets, and possible imposition of foreign withholding taxes. Furthermore, a fund may incur higher costs and expenses when making foreign investments, which will affect the fund’s total return.

• Government Obligations Risk. No assurance can be given that the U.S. government will provide financial support to U.S. government-sponsored agencies or instrumentalities where it is not obligated to do so by law (such as Fannie Mae or Freddie Mac). As a result, a risk exists that these entities will default on a financial obligation.

• High Yield Securities Risk. High yield securities, also referred to as “junk bonds” or non-investment grade securities, tend to be more sensitive to economic conditions than are higher-rated securities, generally involve more credit risk than securities in the higher-rated categories, and are predominantly considered to be speculative. The issuers of high yield securities are typically more leveraged, and the risk of loss due to default by an issuer of high yield securities is significantly greater than issuers of higher-rated securities because such securities are generally unsecured and are often subordinated to other creditors.

• Large-, Mid-, and Small-Cap Risk. Stocks of different market capitalizations tend to go in and out of favor based on market and economic conditions. Historically, small- and mid-cap stocks tend to be more volatile than large-cap stocks, and small-cap stocks have been riskier than large- and mid-cap stocks. During a period when stocks of a particular market capitalization fall behind other types of investments, an underlying fund’s large-, mid-, or small-cap holdings could reduce performance.

• Liquidity Risk. Liquidity risk refers to the possibility that a fund may not be able to sell or buy a security or close out an investment contract at a favorable price or time. Consequently, an underlying fund may have to accept a lower price to sell a security, sell other securities to raise cash, or give up an investment opportunity, any of which could have a negative effect on the fund’s performance.

• REIT Risk. The value of a REIT is affected by changes in the value of the properties owned by the REIT or securing mortgage loans held by the REIT. REITs are also subject to the risks generally associated with investments in real estate, including possible declines in the value of real estate, general and local economic conditions, environmental problems and changes in interest rates. An underlying fund will indirectly bear its proportionate share of any expenses, including management fees, paid by a REIT in which it invests.

• Sector Risk. Companies with similar characteristics, such as those within similar industries, may be grouped together in broad categories called sectors. To the extent an underlying fund invests its assets in a particular sector, the fund’s performance may be more susceptible to any economic, business, or other developments that generally affect that sector.

• Style Risk. Different investment styles, such as growth or equity, tend to shift in and out of favor depending on market and investor sentiment. The Fund may underperform other funds that invest in underlying funds with similar asset classes but employ different investment styles.

Fund Performance

The Fund is the successor to the portfolio of a collective trust fund (Collective Fund) managed by the Adviser with objectives, policies, and restrictions that were, in all material respects, equivalent to those of the Fund. On September 1, 2013, the Fund’s commencement of operations, the assets of the Collective Fund were transferred to the Fund in exchange for Fund shares. The performance information shown for the Class R6 shares includes the performance of the Collective Fund for periods before the Fund commenced operations, not adjusted to reflect the Class R6 expenses. If the Class R6 expenses had been deducted, the returns would be lower than those shown below. The Collective Fund was not registered under the Investment Company Act of 1940, as amended (1940 Act), and was not subject to certain investment restrictions and diversification requirements that are imposed by the 1940 Act and the Internal Revenue Code of 1986, as amended (Code), which, if applicable, might have adversely affected the performance of the Collective Fund.

The bar chart and table show the historical performance of the Collective Fund and the Fund and provide some indication of the risks of investing in the Fund. The bar chart shows how the Collective Fund’s and the Fund’s total returns before taxes have varied from year to year, while the table compares the Collective Fund’s and the Fund’s average annual total returns to the returns of a broad measure of market performance and an index of funds with similar investment objectives. Performance for the Fund’s Class Y and R3 shares will vary from the Class R6 shares based on the expenses of each class. Please keep in mind that past performance does not represent how the Fund will perform in the future both before and after taxes. Investors may obtain updated performance information for the Fund at bmofunds.com.

After-tax returns are calculated using the highest historical individual marginal federal income tax rates and do not reflect the effect of any applicable 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 holding shares through tax-deferred programs, such as IRAs or 401(k) plans. After-tax returns are shown only for Class R6 and after-tax returns for Class Y and Class R3 will vary.

The Return After Taxes on Distributions and Sale of Fund Shares may be higher than other return figures when a capital loss is realized on the sale of Fund shares which provides an assumed tax benefit to the shareholder that increases the after-tax return.

The S&P Target Date 2050 Index (S&P Target Date 2050) is designed to measure the performance of an asset allocation strategy that meets the objectives of investors with an approximate 2050 retirement horizon.

The Lipper Mixed-Asset Target 2050+ Funds Index (LMATFI 2050+) tracks the total return performance of the 30 largest mutual funds included in this Lipper category.

The Russell 3000^® Index (Russell 3000^®) measures the performance of the stocks of the 3,000 largest publicly traded U.S. companies based on market capitalization, and it measures the performance of approximately 98% of the total market capitalization of the publicly traded U.S. equity market.
