SECURITIES, TRANSACTIONS, INVESTMENT TECHNIQUES AND RISKS

The following information supplements the discussion of the Fund’s securities and investment techniques that are described in the Prospectus.

As used in this section, the term Adviser means Adviser or Sub-Adviser, as applicable.

Asset-Backed/Privately-Issued Mortgage-Backed Securities are issued by non-governmental entities and carry no direct or indirect government guarantee. The value and liquidity of asset-backed and mortgage-backed securities in which the Fund invests may be adversely affected by downturns in the sub-prime mortgage lending market. Concerns about defaults on sub-prime loans, which are made to borrowers with low credit ratings and other factors that increase the risk of default, have and may continue to create heightened volatility and turmoil in

the credit markets. Asset-backed and mortgage-backed securities may be supported by credit enhancements. However, there can be no assurance that private insurers or guarantors can meet their obligations under the insurance policies or guarantee arrangements.

Asset-backed securities represent an interest in a pool of assets such as car loans and credit card receivables. Almost any type of fixed income assets (including other fixed income securities) may be used to create an asset-backed security. However, most asset-backed securities involve consumer or commercial debts with maturities of less than ten years. Asset-backed securities may take the form of commercial paper or notes, in addition to pass-through certificates or asset-backed bonds. Asset-backed securities also may resemble some types of collateralized mortgage obligations (CMOs).

Payments on asset-backed securities depend upon assets held by the issuer and collections of the underlying loans. The value of these securities depends on many factors, including changing interest rates, the availability of information about the pool and its structure, the credit quality of the underlying assets, the market’s perception of the servicer of the pool, and any credit enhancement provided. Also, these securities may be subject to prepayment risk.

Mortgage-backed securities represent interests in pools of mortgages. The underlying mortgages normally have similar interest rates, maturities, and other terms. Mortgages may have fixed or adjustable interest rates. Adjustable rate mortgages are known as ARMs.

Mortgage-backed securities come in a variety of forms. Many have extremely complicated terms. The simplest form of mortgage-backed securities is a “pass-through certificate.” Holders of pass-through certificates receive a pro rata share of the payments from the underlying mortgages. Holders also receive a pro rata share of any prepayments, so they assume all the prepayment risk of the underlying mortgages.

CMOs are complicated instruments that allocate payments and prepayments from an underlying pass-through certificate among holders of different classes of mortgage-backed securities. This creates different prepayment and market risks for each CMO class.

In addition, CMOs may allocate interest payments to one class (Interest Only or IOs) and principal payments to another class (Principal Only or POs). POs increase in value when prepayment rates increase. In contrast, IOs decrease in value when prepayments increase, because the underlying mortgages generate fewer interest payments. However, IOs’ prices tend to increase when interest rates rise (and prepayments fall), making IOs a useful hedge against market risk.

Generally, homeowners have the option to prepay their mortgages at any time without penalty. Homeowners frequently refinance high rate mortgages when mortgage rates fall. This results in the prepayment of the mortgages underlying mortgage-backed securities, which deprives holders of the securities of the higher yields. Conversely, when mortgage rates increase, prepayments due to refinancings decline. This extends the life of mortgage-backed securities with lower yields. As a result, increases in prepayments of premium mortgage-backed securities, or decreases in prepayments of discount mortgage-backed securities, may reduce their yield and price.

This relationship between interest rates and mortgage prepayments makes the price of mortgage-backed securities more volatile than most other types of fixed income securities with comparable credit risks. Mortgage-backed securities tend to pay higher yields to compensate for this volatility.

CMOs may include planned amortization classes (PACs) and targeted amortization classes (TACs). PACs and TACs are issued with companion classes. PACs and TACs receive principal payments and prepayments at a specified rate. The companion classes receive principal payments and any prepayments in excess of this rate. In addition, PACs will receive the companion classes’ share of principal payments if necessary to cover a shortfall in the prepayment rate. This helps PACs and TACs to control prepayment risk by increasing the risk to their companion classes.

Another variant allocates interest payments between two classes of CMOs. One class (Floaters) receives a share of interest payments based upon a market index such as London Interbank Offered Rates (LIBOR). The other class (Inverse Floaters) receives any remaining interest payments from the underlying mortgages. Floater classes receive more interest (and Inverse Floater classes receive correspondingly less interest) as interest rates rise. This shifts prepayment and market risks from the Floater to the Inverse Floater class, reducing the price volatility of the Floater class and increasing the price volatility of the Inverse Floater class.

CMOs must allocate all payments received from the underlying mortgages to some class. To capture any unallocated payments, CMOs generally have an accrual (Z) class. Z classes do not receive any payments from the underlying mortgages until all other CMO classes have been paid off. Once this happens, holders of Z class CMOs receive all payments and prepayments. Similarly, real estate mortgage investment conduits (REMICs) (offerings of multiple class mortgage-backed securities that qualify and elect treatment as such under provisions of the Internal Revenue Code of 1986, as amended (Code)) have residual interests that receive any mortgage payments not allocated to another REMIC class.

The degree of increased or decreased prepayment risk depends upon the structure of the CMOs. Z classes, IOs, POs, and Inverse Floaters are among the most volatile investment grade fixed income securities currently traded in the United States. However, the actual returns on any type of mortgage-backed security depend upon the performance of the underlying pool of mortgages, which no one can predict and will vary among pools.

Unlike traditional fixed income securities, which pay a fixed rate of interest until maturity (when the entire principal amount is due), payments on mortgage-backed securities include both interest and a partial payment of principal. Partial payments of principal may be comprised of scheduled principal payments as well as unscheduled payments from the voluntary prepayment, refinancing, or foreclosure of the underlying loans. These unscheduled prepayments of principal create risks that can adversely affect a Fund holding mortgage-backed securities. For example, when interest rates decline, the values of mortgage-backed securities generally rise. However, when interest rates decline, unscheduled prepayments can be expected to accelerate and the Fund would be required to reinvest the proceeds of the prepayments at the lower interest rates then available. Unscheduled prepayments would also limit the potential for capital appreciation on mortgage-backed securities. Conversely, when interest rates rise, the values of mortgage-backed securities generally fall. Since rising interest rates typically result in decreased prepayments, this could lengthen the average lives of mortgage-backed securities and cause their value to decline more than traditional fixed income securities.

Bank Instruments are unsecured interest-bearing deposits with banks. Bank instruments include bank accounts, time deposits, certificates of deposit, and banker’s acceptances. Instruments denominated in U.S. dollars and issued by non-U.S. branches of U.S. or foreign banks are commonly referred to as Eurodollar instruments. Instruments denominated in U.S. dollars and issued by U.S. branches of foreign banks are referred to as Yankee dollar instruments.

The Fund will invest in bank instruments that have been issued by banks and savings and loans that have capital, surplus and undivided profits of over $100 million, or whose principal amount is insured by the Bank Insurance Fund or the Savings Association Insurance Fund, which are administered by the Federal Deposit Insurance Corporation. Securities that are credit-enhanced with a bank’s irrevocable letter of credit or unconditional guaranty also will be treated as bank instruments.

Foreign Bank and Money Market Instruments . Eurodollar Certificates of Deposit (ECDs), Yankee dollar Certificates of Deposit (YCDs), and Eurodollar Time Deposits (ETDs) are all U.S. dollar denominated certificates of deposit. ECDs are issued by, and ETDs are deposits of, foreign banks or foreign branches of U.S. banks. YCDs are issued in the U.S. by branches and agencies of foreign banks. Europaper is dollar-denominated commercial paper and other short-term notes issued in the U.S. by foreign issuers.

ECDs, ETDs, YCDs, and Europaper have many of the same risks as other foreign securities. Examples of these risks include economic and political developments that may adversely affect the payment of principal or

interest, foreign withholding or other taxes, difficulties in obtaining or enforcing a judgment against the issuing bank, and possible interruptions in the flow of international currency transactions. Also, the issuing banks or their branches are not necessarily subject to the same regulatory requirements that apply to domestic banks, such as reserve requirements, loan limitations, examinations, accounting, auditing, recordkeeping, and the public availability of information. These factors will be carefully considered by the Adviser in selecting these investments.

Borrowing . The Fund may borrow money directly or through reverse repurchase agreements and pledge some assets as collateral. If the Fund borrows, it will pay interest on borrowed money and may incur other transaction costs. These expenses could exceed the income received or capital appreciation realized by the Fund from any securities purchased with borrowed money. With respect to borrowings, the Fund is required to maintain continuous asset coverage within the limits of the Investment Company Act of 1940, as amended (1940 Act), and as interpreted or modified by regulatory authority having jurisdiction, from time to time. Borrowing by the Fund will involve special risk considerations, including that the Fund may have to sell portfolio securities to reduce its borrowings and restore the appropriate asset coverage even if it must sell the securities at a loss.

The Corporation has established a line of credit with a bank by which the Fund may borrow money for temporary or emergency purposes.

The Corporation received an exemptive order from the Securities and Exchange Commission (SEC) on July 30, 2014 permitting the Fund to participate in an interfund lending program, subject to its investment policies. This program allows the Fund to lend cash to and borrow cash from other BMO Funds for temporary purposes. The program is subject to a number of conditions, including the requirement that the interfund loan rate to be charged to the Fund under the program is (i) more favorable to the lending Fund than the rate it could otherwise obtain from investing cash in repurchase agreements or purchasing shares of a Money Market Fund and (ii) more favorable to the borrowing Fund than the lowest interest rate at which bank short-term loans would be available to the Fund. The Fund will participate in the program only to the extent that its participation is consistent with the Fund’s investment policies and limitations. The Board is responsible for overseeing and periodically reviewing the interfund lending program.

Collateralized debt obligations. Collateralized debt obligations (CDOs) and similarly structured securities are interests in a trust or other special purpose entity (SPE) and are typically backed by a pool of bonds, loans, or other debt obligations. CDOs are not limited to investments in one type of debt and, accordingly, a CDO may be collateralized by corporate bonds, commercial loans, asset-backed securities, residential mortgage-backed securities, Real Estate Investment Trusts (REITs), commercial mortgage-backed securities, emerging market debt, and municipal bonds. CDOs may use derivatives contracts to create “synthetic” exposure to assets rather than holding such assets directly. There are various types of CDOs, which include collateralized loan obligations and collateralized bond obligations, among others.

CDOs are split into two or more tranches that vary in risk and yield. The equity tranche is the riskiest and the first to suffer a loss from defaults. Senior tranches are less risky and generally have higher ratings and lower yields than the underlying collateral securities held by the trust. All tranches of CDOs, including senior tranches with high credit ratings have recently experienced substantial losses due to actual defaults, increased sensitivity to future defaults due to the disappearance of protecting tranches, market anticipation of defaults, and market aversion to CDO securities as a class. There can be no assurance that additional losses of equal or greater magnitude will not occur in the future.

CDOs carry risks including, but not limited to: (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments; (ii) the quality of the collateral may decline in value or quality or go into default or be downgraded; (iii) the Fund may invest in tranches of a CDO that are subordinate to other classes; and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer, difficulty in valuing the security or unexpected investment results. CDOs also may charge management fees and administrative expenses that the shareholders of the Fund would pay indirectly.

Commercial Paper and Restricted and Illiquid Securities . Commercial paper represents an issuer’s draft or note with a maturity of less than nine months. Companies typically issue commercial paper to fund current expenditures. Most issuers constantly reissue their commercial paper and use the proceeds (or bank loans) to repay maturing paper. Commercial paper may default if the issuer cannot continue to obtain financing in this fashion. The short maturity of commercial paper reduces both the interest rate and credit risk as compared to other debt securities of the same issuer.

The Fund may invest in commercial paper issued under Section 4(a)(2) of the Securities Act of 1933, as amended (1933 Act). By law, the sale of Section 4(a)(2) commercial paper is restricted and is generally sold only to institutional investors, such as the Fund. If the Fund purchases Section 4(a)(2) commercial paper, it must agree to purchase the paper for investment purposes only and not with a view to public distribution. Section 4(a)(2) commercial paper is normally resold to other institutional investors through investment dealers who make a market in Section 4(a)(2) commercial paper and, thus, provide liquidity.

The Adviser determines whether Section 4(a)(2) commercial paper and certain other restricted securities are liquid in accordance with the Fund’s procedures. Section 4(a)(2) commercial paper and other restricted securities that the Adviser has determined to be liquid are not subject to the Fund’s investment limitation applicable to illiquid securities.

Regulation under the Commodity Exchange Act. The Adviser is registered as a “commodity pool operator” (CPO) under the Commodity Exchange Act (CEA) and the rules of the Commodity Futures Trading Commission (CFTC) and is subject to CFTC regulation with respect to the Fund. The CFTC has adopted rules regarding the disclosure, reporting and recordkeeping requirements that will apply with respect to the Fund as a result of the Adviser’s registration as a CPO. Generally, these rules allow for substituted compliance with CFTC disclosure and shareholder reporting requirements, based on the Adviser’s compliance with comparable SEC requirements. This means that for most of the CFTC’s disclosure and shareholder reporting applicable to the Adviser as the Fund’s CPO, the Adviser’s compliance with SEC disclosure and shareholder reporting will be deemed to fulfill the Adviser’s CFTC compliance obligations. However, as a result of CFTC regulation with respect to the Fund, the Fund may incur additional compliance and other expenses. The Adviser is also registered as a “commodity trading advisor” (CTA), but relies on an exemption from CTA regulation available for a CTA that also serves as the Fund’s CPO. The CFTC has neither reviewed nor approved the Fund, its investment strategies, its prospectus or this SAI.

General Tax Risks. The Fund’s investments and investment strategies may be subject to special and complex federal income tax provisions that may, among other things: (i) disallow, suspend or otherwise limit the allowance of certain losses or deductions; (ii) accelerate income to the Fund; (iii) convert long-term capital gain taxable at lower rates into short-term capital gain or ordinary income taxable at higher rates; (iv) convert an ordinary loss or a deduction into a capital loss (the deductibility of which is more limited); (v) treat dividends that would otherwise constitute qualified dividend income as non-qualified dividend income; or (vii) create a risk that the Fund will fail the diversification and source of income requirements under Subchapter M of the Code, which could cause the Fund to fail to qualify for the tax treatment applicable to a regulated investment company (RIC).

Concentration . The Fund has adopted a fundamental investment policy that prohibits the Fund from investing 25% or more of its assets in the securities of companies in any one industry (except as described under “Investment Limitations—Fundamental Limitations—Concentration of Investments”). This policy does not apply to securities in which the Fund may invest that are issued by other investment companies, or to securities issued or guaranteed by the U.S. government, any state or territory of the U.S., its agencies, instrumentalities, or political subdivisions. For purposes of this policy, the Adviser determines industry classifications in accordance with the Global Industry Classification Standards, an industry classification system developed by Standard & Poor’s Corporation in collaboration with Morgan Stanley Capital International, or other sources. In the absence of such classification, or if the Adviser determines in good faith based on its own information that the economic characteristics affecting a particular issuer make it more appropriate to be considered engaged in a different

B-5

Table of Contents

industry, the Adviser may classify an issuer accordingly. Accordingly, the composition of an industry or group of industries may change from time to time. For purposes of the fundamental investment policy regarding industry concentration, “group of industries” means a group of related industries, as determined in good faith by the Adviser, based on published classifications or other sources.

Convertible Securities are fixed income securities that give the holder the option to exchange for equity securities at a specified conversion price within a specified time. The option allows the holder to realize additional returns if the market price of the equity securities exceeds the conversion price. For example, if the holder owns fixed income securities convertible into shares of common stock at a conversion price of $10 per share and the shares have a market value of $12, the holder could realize an additional $2 per share by converting the fixed income securities.

To compensate for the value of the conversion option, convertible securities have lower yields than comparable fixed income securities. In addition, the conversion price exceeds the market value of the underlying equity securities at the time a convertible security is issued. Thus, convertible securities may provide lower returns than non-convertible fixed income securities or equity securities depending upon changes in the price of the underlying equity securities. However, convertible securities permit the holder to realize some of the potential appreciation of the underlying equity securities with less risk of losing its initial investment.

The Fund treats convertible securities as both fixed income and equity securities for purposes of their investment policies and limitations, because of their unique characteristics.

Corporate Debt Securities are fixed income securities issued by businesses. Notes, bonds, debentures, and commercial paper are the most common types of corporate debt securities. The credit risks of corporate debt securities vary widely among issuers.

Credit Enhancement . Certain acceptable investments may be credit-enhanced by a guaranty, letter of credit, or insurance. The Adviser may evaluate a security based, in whole or in part, upon the financial condition of the party providing the credit enhancement (the credit enhancer). The bankruptcy, receivership, or default of the credit enhancer will adversely affect the quality and marketability of the underlying security. In certain cases, credit-enhanced securities may be treated as having been issued both by the issuer and the credit enhancer.

Demand Features . The Fund may purchase securities subject to a demand feature, which may take the form of a put or standby commitment. Demand features permit the holder to demand payment of the value of the security (plus any accrued interest) from either the issuer of the security or a third-party. Demand features help make a security more liquid, although an adverse change in the financial health of the provider of a demand feature (such as bankruptcy) will negatively affect the liquidity of the security. Other events also may terminate a demand feature which also causes liquidity to be affected.

Demand Master Notes are short-term borrowing arrangements between a corporation or government agency and an institutional lender (such as the Fund) payable upon demand by either party. A party may demand full or partial payment, and the notice period for demand typically ranges from one to seven days. Many master notes give the holder the option of increasing or decreasing the principal amount of the master note on a daily or weekly basis within certain limits. Demand master notes usually provide for floating or variable rates of interest.

Depositary Receipts . Depositary receipts are securities representing common stock in non-U.S. issuers. American Depositary Receipts (ADRs) are receipts issued by a U.S. bank that represent an interest in shares of a foreign-based corporation. ADRs provide a way to buy shares of foreign-based companies in the U.S. rather than in overseas markets. European Depositary Receipts (EDRs) and Global Depositary Receipts (GDRs) are receipts issued by foreign banks or trust companies or foreign branches of U.S. banks that represent an interest in shares of either a foreign or U.S. corporation. Depositary receipts may not be denominated in the same currency as the underlying securities into which they may be converted and are subject to currency risks. Depositary receipts involve many of the same risks of investing directly in foreign securities.

Derivative Instruments . Derivative instruments are financial instruments that require payments based upon changes in the values of designated (or underlying) securities, currencies, commodities, financial indices, or other assets. Some derivative instruments (such as futures, forwards, and options) require payments relating to a future trade involving the underlying asset. Other derivative instruments (such as swaps) require payments relating to the income or returns from the underlying asset. The other party to a derivative instrument is referred to as a counterparty.

The Fund, in pursuing its objective and to the extent specified herein or in the Prospectus, may (i) purchase and sell (write) both put options and call options on securities, swap agreements, securities indexes, and foreign currencies, (ii) enter into interest rate, foreign currency, and index futures contracts, and (iii) purchase and sell options on such futures contracts for hedging purposes to seek to replicate the composition and performance of a particular index or as part of their overall investment strategies. The Fund may purchase and sell foreign currency options for purposes of increasing exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one country to another. The Fund may enter into swap agreements with respect to interest rates and indexes of securities, and to the extent the Fund may invest in foreign currency-denominated securities, may enter into swap agreements with respect to foreign currencies. The Fund may invest in structured notes. If other types of financial instruments, including other types of options, futures contracts or futures options, are traded in the future, the Board may authorize their use.

The Fund may use financial futures contracts and options as tools in managing duration, which measures a fixed income security’s average life and reflects the present value of the security’s cash flow. Selling futures contracts or purchasing put options can accomplish the shortening of a portfolio’s duration in anticipation of higher interest rates. Conversely, purchasing futures contracts or call options can accomplish the lengthening of portfolio duration in anticipation of lower interest rates. The use of these instruments in this manner is preferred to either liquidating or purchasing securities held by the Fund to achieve the portfolio’s duration targets because it reduces transaction costs to the Fund. In addition, the use of financial futures contracts and related options permits the Fund’s portfolio managers to react in a more timely manner to changes in interest rates.

The value of some derivative instruments in which the Fund invests may be particularly sensitive to changes in prevailing interest rates and, like the other investments of the Fund, the ability of the Fund to successfully utilize these instruments may depend in part upon the ability of the Fund’s investment adviser to forecast interest rates and other economic factors correctly. If the Fund’s investment adviser or subadviser incorrectly forecasts such factors and has taken positions in derivative instruments contrary to prevailing market trends, the Fund could be exposed to a risk of loss.

The Fund might not employ any of the strategies described herein and no assurance can be given that any strategy used will succeed. If the Adviser incorrectly forecasts interest rates, market values, or other economic factors in utilizing a derivatives strategy for the Fund, the Fund might have been in a better position if it had not entered into the transaction at all. Also, suitable derivative transactions may not be available in all circumstances. The use of these strategies involves certain special risks, including a possible imperfect correlation, or even no correlation, between price movements of derivative instruments and price movements of related investments. Although some strategies involving derivative instruments can reduce the risk of loss for the Fund, they also can reduce the opportunity for gain, or even result in losses, by offsetting favorable price movements in related investments or otherwise due to (i) the possible inability of the Fund to purchase or sell a portfolio security at a time that otherwise would be favorable, (ii) the possible need to sell a portfolio security at a disadvantageous time because the Fund is required to maintain asset coverage or offsetting positions in connection with transactions in derivative instruments, and (iii) the possible inability of the Fund to close out or to liquidate its derivatives positions. In addition, the Fund’s use of such instruments may cause the Fund to realize higher amounts of short-term capital gains (generally taxable to shareholders at ordinary income tax rates for federal income tax purposes) than if it had not used such instruments. If the Fund gains exposure to an asset class using derivative instruments backed by a collateral portfolio of fixed income instruments, changes in the value of the fixed income instruments may result in greater or lesser exposure to that asset class than would have resulted

from a direct investment in securities comprising that asset class. Additionally, a loss may be sustained by the Fund as a result of the failure of a counterparty to a derivative contract to make required payments or otherwise fulfill its obligations under the derivative contract’s terms.

Distressed Securities. The Fund’s investment in distressed securities, which involve loans, loan participations, bonds, notes, non-performing and sub-performing mortgage loans, typically are unrated, lower-rated, in default, or close to default. Many of these instruments are not publicly traded, and may become illiquid. The prices of such instruments may be extremely volatile. Securities of distressed companies are generally more likely to become worthless than the securities of more financially stable companies. Valuing such instruments may be difficult, and the Fund may lose all of its investment, or it may be required to accept cash or securities with a value less than the Fund’s original investment. Issuers of distressed securities are typically in a weak financial condition and may default, in which case the Fund may lose its entire investment.

Exchange-Traded Funds (ETFs). Each share of an ETF represents an undivided ownership interest in the portfolio of stocks held by an ETF. ETFs are investment companies that are bought and sold on a securities exchange. ETFs acquire and hold either (i) shares of all of the companies that are represented by a particular index in the same proportion that is represented in the index itself; or (ii) shares of a sampling of the companies that are represented by a particular index in a proportion meant to track the performance of the entire index.

ETFs are intended to provide investment results that, before expenses, generally correspond to the price and yield performance of the corresponding market index, and the value of their shares should, under normal circumstances, closely track the value of the index’s underlying component stocks. ETFs generally do not buy or sell securities, except to the extent necessary to conform their portfolios to the corresponding index. Because an ETF has operating expenses and transaction costs, while a market index does not, ETFs that track particular indices typically will be unable to match the performance of the index exactly.

ETFs generally do not sell or redeem their shares for cash, and most investors do not purchase or redeem shares directly from an ETF at all. Instead, the ETF issues and redeems its shares in large blocks (typically 50,000 of its shares) called “creation units.” Creation units are issued to anyone who deposits a specified portfolio of the ETF’s underlying securities, as well as a cash payment generally equal to accumulated dividends on the securities (net of expenses) up to the time of deposit, and creation units are redeemed in kind for a portfolio of the underlying securities (based on the ETF’s net asset value) together with a cash payment generally equal to accumulated dividends as of the date of redemption. Most ETF investors, however, purchase and sell ETF shares in the secondary trading market on a securities exchange, in lots of any size, at any time during the trading day. ETF investors generally must pay a brokerage fee for each purchase or sale of ETF shares, including purchases made to reinvest dividends.

Because ETF shares are created from the stocks of an underlying portfolio and can be redeemed into the stocks of an underlying portfolio on any day, arbitrage traders may move to profit from any price discrepancies between the shares and the ETF’s portfolio, which in turn helps to close the price gap between the two. Of course, because of the forces of supply and demand and other market factors, there may be times when an ETF share trades at a premium or discount to its net asset value.

In connection with its investment in ETF shares, the Fund will incur various costs. The Fund may also realize capital gains or losses when ETF shares are sold, and the purchase and sale of the ETF shares may include a brokerage commission that may result in costs. In addition, the Fund is subject to other fees as an investor in ETFs. Generally, those fees include, but are not limited to, Trustees fees, operating expenses, licensing fees, registration fees and marketing expenses, each of which will be reflected in the net asset value of ETFs and therefore the shares representing a beneficial interest therein.

There is a risk that the underlying ETFs in which the Fund invests may terminate due to extraordinary events that may cause any of the service providers to the ETFs, such as the trustee or sponsor, to close or otherwise fail to perform their obligations to the ETF. Also, because the ETFs in which the Fund intends to

B-8

Table of Contents

principally invest are each granted licenses by agreement to use the indices as a basis for determining their compositions and/or otherwise to use certain trade names, the ETFs may terminate if such license agreements are terminated. In addition, an ETF may terminate if its entire net asset value falls below a certain amount. Although the Adviser believes that, in the event of the termination of an underlying ETF, it will be able to invest instead in shares of an alternate ETF tracking the same market index or another market index with the same general market, there is no guarantee that shares of an alternate ETF would be available for investment at that time.

Futures Contracts and Options on Futures Contracts. A futures contract is an agreement between two parties to buy or sell a security or commodity for a set price on a future date. These contracts are traded on exchanges so that, in most cases, either party can close out its position on the exchange for cash without delivering the security or commodity. An option on a futures contract (futures option) gives the holder of the option the right to buy or sell a position in a futures contract to the writer of the option at a specified price and on or before a specified expiration date.

The Fund may invest in financial futures contracts and options thereon with respect to, but not limited to, interest rates and security indexes. To the extent that the Fund may invest in foreign currency-denominated securities, it also may invest in foreign currency futures contracts and options thereon.

An interest rate, commodity, foreign currency, or index futures contract provides for the future sale by one party and purchase by another party of a specified quantity of a financial instrument, commodity, foreign currency, or the cash value of an index at a specified price and time. A futures contract on an index is an agreement pursuant to which two parties agree to take or make delivery of an amount of cash equal to the difference between the value of the index at the close of the last trading day of the contract and the price at which the index contract was originally written. Although the value of an index might be a function of the value of certain specified securities, no physical delivery of those securities is made. A public market exists in futures contracts covering a number of indexes as well as financial instruments and foreign currencies, including the S&P 500, the S&P Midcap 400, the Nikkei 225, the NYSE composite, U.S. Treasury bonds, U.S. Treasury notes, the Government National Mortgage Association (GNMA) Certificates, three-month U.S. Treasury bills, 90-day commercial paper, bank certificates of deposit, Eurodollar certificates of deposit, the Australian dollar, the Canadian dollar, the British pound, the Japanese yen, the Swiss franc, the Mexican peso, and certain multinational currencies, such as the euro. It is expected that other futures contracts will be developed and traded in the future.

The Fund may purchase or write call futures options and put futures options, to the extent specified herein or in the Prospectus. Futures options possess many of the same characteristics as options on securities and indexes (discussed above). A futures option gives the holder the right, in return for the premium paid, to assume a long position (call) or short position (put) in a futures contract at a specified exercise price at any time during the period of the option. Upon exercise of a call option, the holder acquires a long position in the futures contract and the writer is assigned the opposite short position. In the case of a put option, the opposite is true. A call option is “in the money” if the value of the futures contract that is the subject of the option exceeds the exercise price. A put option is “in the money” if the exercise price exceeds the value of the futures contract that is the subject of the option.

Limitations on Use of Futures and Futures Options . The Fund will only enter into futures contracts and futures options that are standardized and traded on a U.S. or foreign exchange, board of trade, or similar entity, or quoted on an automated quotation system.

When a purchase or sale of a futures contract is made by the Fund, the Fund is required to deposit with its custodian (or broker, if legally permitted) a specified amount of assets (initial margin) determined to be liquid by the Adviser. The margin required for a futures contract is set by the exchange on which the contract is traded and may be modified during the term of the contract. Margin requirements on foreign exchanges may be different than U.S. exchanges. The initial margin is in the nature of a performance bond or good faith deposit on the futures contract that is returned to the Fund upon termination of the contract, assuming all contractual obligations

B-9

Table of Contents

have been satisfied. The Fund expects to earn interest income on its initial margin deposits. A futures contract held by the Fund is valued daily at the official settlement price of the exchange on which it is traded. Each day the Fund pays or receives cash, called “variation margin,” equal to the daily change in value of the futures contract. This process is known as “marking to market.” Variation margin does not represent a borrowing or loan by the Fund, but is instead a settlement between the Fund and the broker of the amount one would owe the other if the futures contract expired on that date. In computing daily net asset value, the Fund will mark to market its open futures positions.

The Fund also is required to deposit and maintain margin with respect to put and call options on futures contracts written by it. Such margin deposits will vary depending on the nature of the underlying futures contract (and the related initial margin requirements), the current market value of the option, and other futures positions held by the Fund.

Although some futures contracts call for making or taking delivery of the underlying securities or commodities, generally those obligations are closed out prior to delivery by offsetting purchases or sales of matching futures contracts (same exchange, underlying security or index, and delivery month). Closing out a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If an offsetting purchase price is less than the original sale price, the Fund realizes a capital gain, or if it is more, the Fund realizes a capital loss. Conversely, if an offsetting sale price is more than the original purchase price, the Fund realizes a capital gain, or if it is less, the Fund realizes a capital loss. The transaction costs also must be included in these calculations.

The Fund may write a covered straddle consisting of a call and a put written on the same underlying futures contract. A straddle will be covered when sufficient assets are deposited to meet the Fund’s immediate obligations. The Fund may use the same liquid assets to cover both the call and put options where the exercise price of the call and put are the same, or the exercise price of the call is higher than that of the put. In such a case, the Fund also will segregate liquid assets equivalent to the amount, if any, by which the put is “in the money.”

When purchasing a futures contract, the Fund will maintain assets determined to be liquid by the Adviser with its custodian in an amount that, when added to the amounts deposited with a futures commission merchant as margin are equal to the market value of the instruments underlying the futures contract. These amounts will be marked to market on a daily basis, resulting in adjustments to the amounts maintained with the custodian. Alternatively, the Fund may “cover” its position by purchasing a put option on the same futures contract with a strike price not lower than the price of the contract held by the Fund.

When selling a futures contract, the Fund will maintain assets determined to be liquid by the Adviser with its custodian in an amount that is equal to the market value of the instruments underlying the contract; provided that for cash-settled futures the Fund may segregate only the net amount due on the contract on a mark-to-market basis. These amounts will be marked to market on a daily basis, resulting in adjustments to the amounts maintained with the custodian. Alternatively, the Fund may “cover” its position by owning the instruments underlying the contract (or, in the case of an index futures contract, a portfolio with a volatility substantially similar to that of the index on which the futures contract is based), or by holding a call option permitting the Fund to purchase the same futures contract at a price no higher than the price of the contract written by the Fund (or at a higher price if the difference is maintained in liquid assets with the Fund’s custodian).

When selling a call option on a futures contract, the Fund will maintain assets determined to be liquid by the Adviser with its custodian in an amount that, when added to the amounts deposited with a futures commission merchant as margin, is equal to the market value of the futures contract underlying the call option. These amounts will be marked to market on a daily basis, resulting in adjustments to the amounts maintained with the custodian. Alternatively, the Fund may cover its position by entering into a long position in the same futures contract at a price no higher than the strike price of the call option, by owning the instruments underlying the futures contract, or by holding a separate call option permitting the Fund to purchase the same futures contract at a price not higher than the strike price of the call option sold by the Fund.

When selling a put option on a futures contract, the Fund will maintain assets determined to be liquid by the Adviser with its custodian in an amount that is equal to the purchase price of the futures contract, less any margin on deposit. These amounts will be marked to market on a daily basis, resulting in adjustments to the amounts maintained with the custodian. Alternatively, the Fund may cover the position either by entering into a short position in the same futures contract, or by owning a separate put option permitting it to sell the same futures contract, so long as the strike price of the purchased put option is not lower than the strike price of the put option sold by the Fund.

To the extent that securities with maturities greater than one year are used to cover the Fund’s obligations under futures contracts and related options, such use will not eliminate the risk of a form of leverage, which may tend to exaggerate the effect on net asset value of any increase or decrease in the market value of the Fund’s portfolio and may require liquidation of portfolio positions when it is not advantageous to do so. However, any potential risk of leverage resulting from the use of securities with maturities greater than one year may be mitigated by the overall duration limit on the Fund’s portfolio securities. Thus, the use of a longer-term security may require the Fund to hold offsetting short-term securities to balance the Fund’s portfolio such that the Fund’s duration does not exceed the maximum permitted for the Fund in its Prospectus.

The requirements for qualification as a regulated investment company (RIC) under the Code also may limit the extent to which the Fund may enter into futures, futures options, or forward contracts.

Risks Associated with Futures and Options Generally. The following describes the general risks of investing in futures and options:

Management Risk . Financial futures contracts and related options are highly specialized instruments that require investment techniques and risk analyses different from those associated with stocks and bonds. The Fund’s use of financial futures and options may not always be a successful strategy and using them could lower the Fund’s return. Further, if the Adviser incorrectly forecasts interest rates or other economic factors and has taken positions in financial futures contracts or options contrary to prevailing market trends, the Fund could be exposed to a risk of loss.

Correlation Risk . Imperfect correlation between the change in market values of the securities held by the Fund and the prices of related futures contracts and options on futures purchased or sold by the Fund may result in losses in excess of the amount invested in these instruments.

Market Risk . Financial futures contracts and related options, like most other investments, are subject to the risk that the market value of the investment will decline. Adverse movements in the value of the underlying assets can expose the Fund to losses.

Exchange Limit Risk . Futures exchanges may limit the amount of fluctuation permitted in certain futures contract prices during a single trading day. The daily limit establishes the maximum amount that the price of a futures contract may vary either up or down from the previous day’s settlement price at the end of the current trading session. Once the daily limit has been reached in a futures contract subject to the limit, no more trades may be made on that day at a price beyond that limit. The daily limit governs only price movements during a particular trading day and therefore does not limit potential losses because the limit may work to prevent the liquidation of unfavorable positions. For example, futures prices have occasionally moved to the daily limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of positions and subjecting some holders of futures contracts to substantial losses.

Liquidity Risk . There can be no assurance that a liquid market will exist at a time when the Fund seeks to close out a futures or a futures option position, in which case the Fund would remain obligated to meet margin requirements until the position is closed. In addition, many of the contracts discussed herein are relatively new instruments without a significant trading history. As a result, there can be no assurance that an active secondary market will develop or continue to exist.

B-11

Table of Contents

Counterparty Risk. A loss may be sustained as a result of the failure of another party to the contract to make required payments or otherwise fulfill its obligations under the contract’s terms.

Risks Associated with Hedging Transactions. Several risks are associated with the use of futures contracts and futures options as hedging techniques. A purchase or sale of a futures contract may result in losses in excess of the amount invested in the futures contract. No guarantee exists that there will be a correlation between price movements in the hedging vehicle and in the Fund securities being hedged. In addition, significant differences may exist between the securities and futures markets that could result in an imperfect correlation between the markets, causing a given hedge not to achieve its objective. The degree of imperfection of correlation depends on circumstances such as variations in speculative market demand for futures and futures options on securities, including technical influences in futures trading and futures options and differences between the financial instruments being hedged and the instruments underlying the standard contracts available for trading in such respects as interest rate levels, maturities, and creditworthiness of issuers. A decision as to whether, when, and how to hedge involves the exercise of skill and judgment. Even a well-conceived hedge may be unsuccessful to some degree because of market behavior or unexpected interest rate trends.

Options on Securities and Indexes. The Fund may, to the extent specified herein or in the Prospectus, purchase and sell both put and call options on fixed income or other securities or indexes in standardized contracts traded on foreign or domestic securities exchanges, boards of trade or similar entities, or quoted on NASDAQ or on an over-the-counter market, and agreements, sometimes called cash puts, which may accompany the purchase of a new issue of bonds from a dealer.

An option on a security (or index) is a contract that gives the holder of the option, in return for a premium, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the security underlying the option (or the cash value of the index) at a specified exercise price at any time during the term of the option. The writer of an option on a security has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price or to pay the exercise price upon delivery of the underlying security. Upon exercise, the writer of an option on an index is obligated to pay the difference between the cash value of the index and the exercise price multiplied by the specified multiplier for the index option. (An index is designed to reflect features of a particular financial or securities market, a specific group of financial instruments or securities, or certain economic indicators.)

The Fund will not write a call option or put option unless the option is “covered.” In the case of a call option on a security, the option is “covered” if the Fund owns the security underlying the call or has an absolute and immediate right to acquire that security without additional cash consideration upon conversion or exchange of other securities held by the Fund (or, if additional cash consideration is required, cash or other assets determined to be liquid in such amount are segregated). For a call option on an index, the option is covered if the Fund maintains with its custodian assets determined to be liquid by the Adviser in an amount equal to the contract value of the index. A call option also is covered if the Fund holds a call on the same security or index as the call written where the exercise price of the call held is (i) equal to or less than the exercise price of the call written, or (ii) greater than the exercise price of the call written, provided the difference is maintained by the Fund in segregated assets determined to be liquid by the Adviser. A put option on a security or an index is “covered” if the Fund segregates assets determined to be liquid by the Adviser equal to the exercise price. A put option is also covered if the Fund holds a put on the same security or index as the put written where the exercise price of the put held is (i) equal to or greater than the exercise price of the put written, or (ii) less than the exercise price of the put written, provided the difference is maintained by the Fund in segregated assets determined to be liquid by the Adviser.

If an option written by the Fund expires unexercised, the Fund realizes a short-term capital gain equal to the premium received at the time the option was written. If an option purchased by the Fund expires unexercised, the Fund realizes a capital loss equal to the premium paid. Prior to the earlier of exercise or expiration, an exchange

B-12

Table of Contents

traded option may be closed out by an offsetting purchase or sale of an option of the same series (type, exchange, underlying security or index, exercise price, and expiration). No assurance exists, however, that a closing purchase or sale transaction can be effected when the Fund desires.

The Fund may sell a put or call option it has previously purchased, which could result in a net gain or loss depending on whether the amount realized on the sale is more or less than the premium and other transaction costs paid on the put or call option being sold. Prior to exercise or expiration, an option may be closed out by an offsetting purchase or sale of an option of the same series. The Fund will realize a capital gain from a closing purchase transaction if the cost of the closing option is less than the premium received from writing the option or, if it is more, the Fund will realize a capital loss. If the premium received from a closing sale transaction is more than the premium paid to purchase the option, the Fund will realize a capital gain or, if it is less, the Fund will realize a capital loss. The principal factors affecting the market value of a put or a call option include supply and demand, interest rates, the current market price of the underlying security or index in relation to the exercise price of the option, the volatility of the underlying security or index, and the time remaining until the expiration date.

The premium paid for a put or call option purchased by the Fund is an asset of the Fund. The premium received for an option written by the Fund is recorded as a deferred credit. The value of an option purchased or written is marked to market daily and is valued at the closing price on the exchange on which it is traded or, if not traded on an exchange or no closing price is available, at the mean between the last bid and asked prices.

The Fund may write a covered straddle consisting of a combination of a call and a put written on the same underlying security. A straddle will be covered when sufficient assets are designated for such purpose on the Fund’s books to meet the Fund’s immediate obligation. The Fund may use the same liquid assets to cover both the call and put options where the exercise price of the call and put are the same, or the exercise price of the call is higher than that of the put. In such a case, the Fund will also segregate liquid assets equivalent to the amount, if any, by which the put is “in the money.”

Several risks are associated with transactions in options on securities and on indexes. For example, significant differences exist between the securities and options markets that could result in an imperfect correlation between these markets, causing a given transaction not to achieve its objective. A decision as to whether, when, and how to use options involves the exercise of skill and judgment. Even a well-conceived transaction may be unsuccessful to some degree because of market behavior or unexpected events.

During the option period, the covered call writer has, in return for the premium on the option, given up the opportunity to profit from a price increase in the underlying security above the exercise price, but, as long as its obligation as a writer continues, has retained the risk of loss should the price of the underlying security decline.

The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. Once an option writer has received an exercise notice, it cannot effect a closing purchase transaction to terminate its obligation under the option and must deliver the underlying security at the exercise price. If a put or call option purchased by the Fund is not sold when it has remaining value, and if the market price of the underlying security remains equal to or greater than the exercise price (in the case of a put) or remains less than or equal to the exercise price (in the case of a call), the Fund will lose its entire investment in the option. Also, where a put or call option on a particular security is purchased to hedge against price movements in a related security, the price of the put or call option may move more or less than the price of the related security.

No assurance exists that there will be a liquid market when the Fund seeks to close out an option position. If the Fund were unable to close out an option that it had purchased on a security, it would have to exercise the option to realize any profit or the option may expire worthless. If the Fund were unable to close out a covered call option that it had written on a security, it would not be able to sell the underlying security unless the option

B-13

Table of Contents

expired without exercise. As the writer of a covered call option, the Fund forgoes, during the option’s life, the opportunity to profit from increases in the market value of the security covering the call option above the sum of the premium and the exercise price of the call.

If trading were suspended in an option purchased by the Fund, the Fund would not be able to close out the option. If restrictions on exercise were imposed, the Fund might be unable to exercise an option it had purchased. Except to the extent that a call option on an index written by the Fund is covered by an option on the same index purchased by the Fund, movements in the index may result in a loss to the Fund; however, such losses may be mitigated by changes in the value of the Fund’s securities during the period the option was outstanding.

Foreign Currency Transactions . Foreign currency transactions generally are used by the Fund to obtain foreign currencies to settle securities transactions. They also can be used as a hedge to protect assets against adverse changes in foreign currency exchange rates or regulations. When the Fund uses foreign currency exchanges as a hedge, it also may limit potential gain that could result from an increase in the value of such currencies. The Fund may be affected either favorably or unfavorably by fluctuations in the relative rates of exchange between the currencies of different nations. Foreign currency hedging transactions include forward foreign currency exchange contracts, foreign currency futures contracts, and purchasing put or call options on foreign currencies.

Exchange-Traded Futures Contracts. Exchange-traded futures contracts for the purchase or sale of foreign currencies (Foreign Currency Futures) are used to hedge against anticipated changes in exchange rates that might adversely affect the value of the Fund’s portfolio securities or the prices of securities that the Fund intends to purchase in the future. The successful use of Foreign Currency Futures depends on the ability to forecast currency exchange rate movements correctly. Should exchange rates move in an unexpected manner, the Fund may not achieve the anticipated benefits of Foreign Currency Futures or may realize losses.

Forward Foreign Currency Exchange Contracts. Forward foreign currency exchange contracts (Forward Contracts) are used to minimize the risks associated with changes in the relationship between the U.S. dollar and foreign currencies. They are used to lock in the U.S. dollar price of a foreign security. A Forward Contract is a commitment to purchase or sell a specific currency for an agreed price at a future date.

If the Adviser believes a foreign currency will decline against the U.S. dollar, a Forward Contract may be used to sell an amount of the foreign currency approximating the value of the Fund’s security that is denominated in the foreign currency. The success of this hedging strategy is highly uncertain due to the difficulties of predicting the values of foreign currencies, the challenges of precisely matching Forward Contract amounts, and because of the constantly changing value of the securities involved. The Fund will not enter into Forward Contracts for hedging purposes in a particular currency in an amount in excess of the Fund’s assets denominated in that currency. Conversely, if the Adviser believes that the U.S. dollar will decline against a foreign currency, a Forward Contract may be used to buy that foreign currency for a fixed dollar amount, which is known as cross-hedging.

In these transactions, the Fund will segregate assets with a market value equal to the amount of the foreign currency purchased. Therefore, the Fund will always have cash, cash equivalents, or high quality debt securities available to cover Forward Contracts or to limit any potential risk. The segregated assets will be priced daily.

Forward Contracts may limit potential gain from a positive change in the relationship between the U.S. dollar and foreign currencies. Unanticipated changes in currency prices may result in poorer overall performance for the Fund than if it had not engaged in such contracts.

Some Forward Contracts do not provide for physical settlement of two currencies. Instead, these contracts are settled by a single cash payment calculated as the difference between the agreed upon exchange rate and the spot rate at settlement based upon an agreed upon notional amount (a non-deliverable forward). Under definitions adopted by the CFTC and the Securities and Exchange Commission, non-deliverable forwards

B-14

Table of Contents

are considered swaps. Although non-deliverable forwards have historically been traded in the over-the-counter (OTC) market, as swaps, they may in the future be required to be centrally cleared and traded on public facilities. For more information on central clearing and trading of cleared swaps, see the later discussion of “Swap Agreements and Options on Swap Agreements.”

Foreign Currency Options. The Fund that invests in foreign currency-denominated securities may buy or sell put and call options on foreign currencies, either on U.S. or foreign exchanges or in the over-the-counter market. A put option on a foreign currency gives the purchaser of the option the right to sell a foreign currency at the exercise price until the option expires. A call option on a foreign currency gives the purchaser of the option the right to purchase the currency at the exercise price until the option expires. Currency options traded on U.S. or other exchanges may be subject to position limits that may limit the ability of the Fund to reduce foreign currency risk using such options. Over-the-counter options differ from traded options in that they are two-party contracts with price and other terms negotiated between buyer and seller and generally do not have as much market liquidity as exchange-traded options.

Purchasing and writing put and call options on foreign currencies are used to protect the Fund’s portfolio against declines in the U.S. dollar value of foreign portfolio securities and against increases in the dollar cost of foreign securities to be acquired. Writing an option on foreign currency constitutes only a partial hedge, up to the amount of the premium received. The Fund could lose money if it is required to purchase or sell foreign currencies at disadvantageous exchange rates. If exchange rate movements are adverse to the Fund’s position, the Fund may forfeit the entire amount of the premium as well as incur related transaction costs.

Additional Risks of Futures Contracts and Options. Options on securities, futures contracts, and foreign currencies may be traded on foreign exchanges. Such transactions may not be regulated as effectively as similar transactions in the United States, may not involve a clearing mechanism and related guarantees, and are subject to the risk of governmental actions affecting trading in, or the prices of, foreign securities. The value of such positions also could be adversely affected by (i) other complex foreign political, legal, and economic factors; (ii) lesser availability than in the United States of data on which to make trading decisions; (iii) delays in the Fund’s ability to act upon economic events occurring in foreign markets during non-business hours in the United States; (iv) the imposition of different exercise and settlement terms and procedures and margin requirements than in the United States; and (v) lesser trading volume.

Swap Agreements and Options on Swap Agreements. The Fund may engage in swap transactions, including, but not limited to, swap agreements on interest rates, security indexes, specific securities, and credit and event-linked swaps. To the extent the Fund may invest in foreign currency-denominated securities, it also may invest in currency exchange rate swap agreements. The Fund also may enter into options on swap agreements (swap options).

The Fund may enter into swap transactions for any legal purpose consistent with its investment objective and policies, such as for the purpose of attempting to obtain or preserve a particular return or spread at a lower cost than obtaining a return or spread through purchases and/or sales of instruments in other markets, to protect against currency fluctuations, as a duration management technique, to protect against any increase in the price of securities the Fund anticipates purchasing at a later date, or to gain exposure to certain markets in the most economical way possible.

Swap agreements have traditionally been two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard swap transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or swapped between the parties are generally calculated with respect to a “notional amount,” i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate, in a particular foreign currency, or in a basket of securities representing a particular index. A “quanto” or “differential” swap combines both an interest rate and a currency transaction. Other forms of swap agreements include interest rate caps, under

B-15

Table of Contents

which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”; interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or “floor”; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels. With a floating rate, the fee may be pegged to a base rate, such as the LIBOR and is adjusted each period. Therefore, if interest rates increase over the term of the swap contract, the Fund may be required to pay a higher fee at each swap reset date.

The Fund may enter into credit default swap agreements. The buyer in a credit default contract is obligated to pay the seller a periodic stream of payments over the term of the contract provided that no event of default on an underlying reference obligation has occurred. If an event of default occurs, the seller must pay the buyer the full notional value, or “par value,” of the reference obligation in exchange for the reference obligation. The Fund may be either the buyer or seller in a credit default swap transaction. If the Fund is a buyer and no event of default occurs, the Fund will lose its investment and recover nothing. However, if an event of default occurs, the Fund (as the buyer) will receive the full notional value of a reference obligation that may have little or no value. As a seller, the Fund receives a fixed rate of income throughout the term of the contract, which typically is between six months and three years, provided that there is no default event. If an event of default occurs, the seller must pay the buyer the full notional value of the reference obligation. Credit default swap transactions involve greater risks than if the Fund had invested in the reference obligation directly.

A swap option is a contract that gives a counterparty the right (but not the obligation) in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel, or otherwise modify an existing swap agreement at some designated future time on specified terms. The Fund may write (sell) and purchase put and call swap options.

Most swap agreements entered into by the Fund would calculate the obligations of the parties to the agreement on a net basis. Consequently, the Fund’s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the net amount). The Fund’s current obligations under a swap agreement will be accrued daily (offset against any amounts owed to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by the segregation of assets determined to be liquid by the Adviser, to avoid any potential leveraging of the Fund’s portfolio. Obligations under swap agreements so covered will not be construed to be senior securities for purposes of the Fund’s investment restriction concerning senior securities. The Fund will not enter into a swap agreement with any single party if the net amount owed or to be received under existing contracts with that party would exceed 5% of the Fund’s total assets.

Whether the Fund’s use of swap agreements or swap options will be successful in furthering its investment objective will depend on the ability of the Adviser to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The Fund will enter into swap agreements only with counterparties that meet certain standards of creditworthiness (generally, such counterparties would have to be eligible counterparties under the terms of the Fund’s repurchase agreement guidelines). Certain restrictions imposed on the Fund by the Code for qualification as a RIC may limit the Fund’s ability to use swap agreements. It is possible that developments in the swaps market, including anticipated government regulations, could affect the Fund’s ability to utilize swaps.

Depending on the terms of the particular option agreement, the Fund will generally incur a greater degree of risk when it writes a swap option than it will incur when it purchases a swap option. When the Fund purchases a swap option, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swap option, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement.

B-16

Table of Contents

Notwithstanding the foregoing, some swaps currently are, and more in the future will be, centrally cleared. Swaps that are centrally cleared are subject to the creditworthiness of the clearing organization involved in the transaction. For example, an investor could lose margin payments it has deposited with its futures commission merchant as well as the net amount of gains not yet paid by the clearing organization if the clearing organization becomes insolvent or goes into bankruptcy. In the event of bankruptcy of the clearing organization, the investor may be entitled to the net amount of gains the investor is entitled to receive plus the return of margin owed to it only in proportion to the amount received by the clearing organization’s other customers, potentially resulting in losses to the investor.

Structured Notes and Indexed Securities . Structured notes are derivative debt securities, the interest rate or principal of which is determined by an unrelated indicator. Indexed securities include structured notes as well as securities other than debt securities, the interest rate or principal of which is determined by an unrelated indicator. Indexed securities may include a multiplier that multiplies the indexed element by a specified factor and, therefore, the value of such securities may be very volatile. To the extent the Fund invests in these securities, however, the Adviser analyzes these securities in its overall assessment of the effective duration of the Fund’s portfolio in an effort to monitor the Fund’s interest rate risk.

Hybrid Instruments. A hybrid instrument is a type of potentially high-risk derivative that combines a traditional stock, bond, or commodity with an option or forward contract. Generally, the principal amount, amount payable upon maturity or redemption, or interest rate of a hybrid is tied (positively or negatively) to the price of some commodity, currency or securities index, or another interest rate, or some other economic factor (each a benchmark). The interest rate or (unlike most fixed income securities) the principal amount payable at maturity of a hybrid security may be increased or decreased, depending on changes in the value of the benchmark. An example of a hybrid could be a bond issued by an oil company that pays a small base level of interest with additional interest that accrues in correlation to the extent to which oil prices exceed a certain predetermined level. Such a hybrid instrument would be a combination of a bond and a call option on oil.

Hybrids can be used as an efficient means of pursuing a variety of investment objectives, including currency hedging, duration management, and increased total return. Hybrids may not bear interest or pay dividends. The value of a hybrid or its interest rate may be a multiple of a benchmark and, as a result, may be leveraged and move (up or down) more steeply and rapidly than the benchmark. These benchmarks may be sensitive to economic and political events, such as commodity shortages and currency devaluations, that cannot be readily foreseen by the purchaser of a hybrid. Under certain conditions, the redemption value of a hybrid could be zero. Thus, an investment in a hybrid may entail significant market risks that are not associated with a similar investment in a traditional, U.S. dollar-denominated bond that has a fixed principal amount and pays a fixed rate or floating rate of interest. The Fund’s purchase of a hybrid also exposes the Fund to the credit risk of the issuer of the hybrid. Those risks may cause significant fluctuations in the net asset value of the Fund. The Fund will not invest more than 5% of its total assets at time of investment in hybrid instruments.

Certain issuers of structured products such as hybrid instruments may be deemed to be investment companies as defined in the 1940 Act. As a result, the Fund’s investments in those products may be subject to limits applicable to investments in investment companies and may be subject to restrictions contained in the 1940 Act.

Dollar Rolls are transactions whereby the Fund sells mortgage-backed securities with a commitment to buy similar, but not identical, mortgage-backed securities on a future date at a lower price. Normally, one or both securities involved are “to be announced” mortgage-backed securities. Dollar rolls are subject to interest rate risks and credit risks. These transactions may create leverage risks. Dollar roll transactions will cause the Fund to have an increased portfolio turnover rate.

Duration is a measure of volatility in the price of a bond prior to maturity. Volatility is the magnitude of the change in the price of a bond relative to a change in the market interest rate. Volatility is based upon a bond’s coupon rate, maturity date and the level of market yields of similar bonds. Generally, bonds with lower coupons

B-17

Table of Contents

or longer maturities will be more volatile than bonds with higher coupons or shorter maturities. Duration combines these variables into a single measure of price sensitivity to interest rate changes. For example, if interest rates decline by 1%, the market value of a portfolio with a duration of five years would rise by approximately 5%. Conversely, if interest rates increase by 1%, the market value of the portfolio would decline by approximately 5%.

Equity Securities are fundamental units of ownership in a company. The following describes the types of equity securities in which the Fund may invest:

Common Stocks are the most prevalent type of equity security. Common stockholders are entitled to the net value of the issuer’s earnings and assets after the issuer pays its creditors and any preferred stockholders. As a result, changes in an issuer’s earnings directly influence the value of its common stock.

Common Stocks of Foreign Companies are equity securities issued by a corporation domiciled outside of the United States that trade on a domestic securities exchange.

Master Limited Partnerships (MLPs) and Other Publicly Traded Partnerships are limited partnerships (or limited liability companies), the units of which are listed and traded on a securities exchange. The Fund may invest in publicly traded partnerships that are expected to be treated as “qualified publicly traded partnerships” for federal income tax purposes. These include MLPs and other entities qualifying under limited exceptions in the Code. Many MLPs derive income and capital gains from the exploration, development, mining or production, processing, refining, transportation or marketing of any mineral or natural resource, or from real property. The value of MLP units fluctuates predominantly based on prevailing market conditions and the success of the MLP. The Fund may purchase common units of an MLP on an exchange as well as directly from the MLP or other parties in private placements. Unlike owners of common stock of a corporation, owners of common units have limited voting rights and have no ability to annually elect directors.

MLPs generally distribute all available cash flow (cash flow from operations less maintenance capital expenditures) in the form of quarterly distributions, but the Fund will be required for federal income tax purposes to include in its taxable income its allocable share of the MLP’s income regardless of whether any distributions are made by the MLP. Thus, if the distributions received by the Fund from an MLP are less than the Fund’s allocable share of the MLP’s income, the Fund may be required to sell other securities so that it may satisfy the requirements to qualify as a RIC and avoid federal income and excise taxes. Common units typically have priority as to minimum quarterly distributions. In the event of liquidation, common units have preference over subordinated units, but not debt or preferred units, to the remaining assets of the MLP.

Holders of MLP units of a particular MLP also are exposed to a remote possibility of liability for the obligations of that MLP under limited circumstances not expected to be applicable to the Fund. In addition, the value of the Fund’s investment in MLPs depends largely on the MLPs being treated as “qualified publicly traded partnerships” for federal income tax purposes. If an MLP does not meet current federal income tax requirements to maintain partnership status, or if it is unable to do so because of federal income tax law changes, it could be taxed as a corporation. In that case, the MLP would be obligated to pay federal income tax at the entity level and distributions received by the Fund generally would be taxed as dividend income for federal income tax purposes. As a result, there could be a reduction in the Fund’s cash flow and there could be a material decrease in the value of the Fund’s shares. In addition, if an MLP in which the Fund invests does not qualify as a “qualified publicly traded partnership” (and is otherwise not taxed as a corporation), the Fund must look through to the character of the income generated by the MLP. Such income may not qualify as “good income,” and therefore, could adversely affect the Fund’s status as a RIC.

Preferred Stocks have the right to receive specified dividends or distributions before the payment of dividends or distributions on common stock. Some preferred stocks also participate in dividends and distributions paid on common stock. Preferred stocks may provide for the issuer to redeem the stock on a specified date. The Fund may treat redeemable preferred stock as a fixed income security.

Warrants provide an option to buy the issuer’s stock or other equity securities at a specified price. When holding a warrant, the Fund may buy the designated shares by paying the exercise price before the warrant expires. Warrants may become worthless if the price of the stock does not rise above the exercise price by the stated expiration date. Rights are the same as warrants, except they are typically issued to existing stockholders.

Fixed Income Securities generally pay interest at either a fixed or floating rate and provide more regular income than equity securities. However, the returns on fixed income securities are limited and normally do not increase with the issuer’s earnings. This limits the potential appreciation of fixed income securities as compared to equity securities. Fixed-rate securities and floating rate securities react differently as prevailing interest rates change.

Callable Securities . Certain fixed income securities in which the Fund invests are callable at the option of the issuer. Callable securities are subject to call risks. Call risks include the risk that the securities in which the Fund invests may be redeemed by the issuer before maturity. If this occurs, the Fund may have to reinvest the proceeds in securities that pay a lower interest rate, which may decrease the Fund’s yield.

Fixed Rate Debt Securities. Debt securities that pay a fixed interest rate over the life of the security and have a long-term maturity may have many characteristics of short-term debt. For example, the market may treat fixed-rate/long-term securities as short-term debt when a security’s market price is close to the call or redemption price, or if the security is approaching its maturity date when the issuer is more likely to call or redeem the debt.

As interest rates change, the market prices of fixed-rate debt securities are generally more volatile than the prices of floating rate debt securities. As interest rates rise, the prices of fixed-rate debt securities fall, and as interest rates fall, the prices of fixed-rate debt securities rise. For example, a bond that pays a fixed interest rate of 10% is more valuable to investors when prevailing interest rates are lower; this value is reflected in a higher price, or premium. Conversely, if interest rates are over 10%, the bond is less attractive to investors, and sells at a lower price, or discount.

Floating Rate Debt Securities. The interest rate paid on floating rate debt securities is reset periodically (e.g., every 90 days) to a predetermined index rate. Commonly used indices include 90-day or 180-day Treasury bill rates; one month or three month LIBOR; commercial paper rates; or the prime rate of interest of a bank. The prices of floating rate debt securities are not as sensitive to changes in interest rates as fixed rate debt securities because they behave like shorter-term securities and their interest rate is reset periodically.

Foreign Securities include securities (i) of issuers domiciled outside of the United States, including securities issued by foreign governments, (ii) that primarily trade on a foreign securities exchange or in a foreign market, or (iii) that are subject to substantial foreign risk based on factors such as whether a majority of an issuer’s revenue is earned outside of the United States and whether an issuer’s principal business operations are located outside of the United States.

Investing in foreign securities, including foreign corporate debt securities and foreign equity securities, involves certain risks not ordinarily associated with investments in securities of domestic issuers. Foreign securities markets have, for the most part, substantially less volume than the U.S. markets and securities of many foreign companies are generally less liquid and their prices more volatile than securities of U.S. companies. Less government supervision and regulation exist of foreign exchanges, brokers, and issuers than in the U.S. The rights of investors in certain foreign countries may be more limited than those of shareholders of U.S. issuers and investors may have greater difficulty taking appropriate legal action to enforce their rights in a foreign court than in a U.S. court. Investing in foreign securities also involves risks associated with government, economic, monetary, and fiscal policies (such as the adoption of protectionist trade measures), possible foreign withholding taxes on dividends and interest, possible taxes on trading profits, inflation, and interest rates, economic expansion or contraction, and global or regional political, economic, or banking crises. Furthermore, the risk exists of

B-19

Table of Contents

possible seizure, nationalization, or expropriation of the foreign issuer or foreign deposits, and the possible adoption of foreign government restrictions such as exchange controls. Also, foreign issuers are not necessarily subject to uniform accounting, auditing, and financial reporting standards, practices, and requirements comparable to those applicable to domestic issuers and, as a result, less publicly available information on such foreign issuers may be available than a domestic issuer.

Emerging Markets Securities are fixed income and equity securities of foreign companies domiciled, headquartered, or whose primary business activities or principal trading markets are located in emerging and less developed markets (emerging markets). Investments in emerging markets securities involve special risks in addition to those generally associated with foreign investing. Many investments in emerging markets can be considered speculative and the value of those investments can be more volatile than investments in more developed foreign markets. This difference reflects the greater uncertainties of investing in less established markets and economies. Costs associated with transactions in emerging markets securities typically are higher than costs associated with transactions in U.S. securities. Such transactions also may involve additional costs for the purchase or sale of foreign currency.

Certain foreign markets (including emerging markets) may require governmental approval for the repatriation of investment income, capital, or the proceeds of sales of securities by foreign investors. The Fund could be adversely affected by delays in, or a refusal to grant, required governmental approval for repatriation of capital, as well as by the application to the Fund of any restrictions on investments.

Many emerging markets have experienced substantial rates of inflation for extended periods. Inflation and rapid fluctuations in inflation rates have had and may continue to have adverse effects on the economies and securities markets of certain emerging market countries.

Governments of many emerging market countries have exercised and continue to exercise substantial influence over many aspects of the private sector through ownership or control of many companies. The future actions of those governments could have a significant effect on economic conditions in emerging markets, which, in turn, may adversely affect companies in the private sector, general market conditions and prices and yields of certain of the securities in the Fund’s portfolio. Expropriation, confiscatory taxation, nationalization and political, economic, and social instability have occurred throughout the history of certain emerging market countries and could adversely affect Fund assets should any of those conditions recur. In addition, the securities laws of emerging market countries may be less developed than those to which U.S. issuers are subject.

Participatory Notes , which are a type of equity access product, are structured as unsecured and unsubordinated debt securities designed to replicate exposure to the underlying referenced equity investment and are sold by a bank or a broker-dealer in markets where the Fund is restricted from directly purchasing equity securities. The Fund may tender a participatory note for cash payment in an amount that reflects the current market value of the referenced underlying equity investments, reduced by program fees. Participatory notes involve risks that are in addition to the risks normally associated with a direct investment in the underlying equity securities. The issuer of a participatory note may be unable or may refuse to perform under the terms of the participatory note. While the holder of a participatory note is entitled to receive from the issuing bank or broker-dealer any dividends or other distributions paid on the underlying securities, the holder is not entitled to the same rights as an owner of the underlying securities, such as voting rights. Participatory notes are also not traded on exchanges, are privately issued, and may be illiquid. To the extent a participatory note is determined to be illiquid, it would be subject to the Fund’s limitations on investments in illiquid securities. There can be no assurance that the trading price or value of participatory notes will equal the value of the underlying equity securities they seek to replicate.

Funding Agreements (Agreements) are investment instruments issued by U.S. insurance companies. Pursuant to such Agreements, The Fund may make cash contributions to a deposit fund of the insurance company’s general or separate accounts. The insurance company then credits guaranteed interest to the Fund. The insurance company may assess periodic charges against an Agreement for expense and service costs

B-20

Table of Contents

allocable to it and the charges will be deducted from the value of the deposit fund. The purchase price paid for an Agreement becomes part of the general assets of the issuer and the Agreement is paid from the general assets of the issuer.

High Yield Securities (Junk Bonds) are securities rated below investment grade. The Fund may hold high yield securities if securities it holds are not rated, rated below investment grade, or are downgraded below investment grade. While generally offering higher yields than investment grade securities with similar maturities, non-investment grade debt securities involve greater risks, including the possibility of default or bankruptcy. They are regarded as predominantly speculative with respect to the issuer’s capacity to pay interest and repay principal. The special risk considerations in connection with investments in these securities are discussed below. Refer to Appendix A of this SAI for a discussion of securities credit ratings.

Effect of Interest Rates and Economic Changes. All interest-bearing securities typically experience appreciation when interest rates decline and depreciation when interest rates rise. The market values of high yield securities tend to reflect individual corporate developments to a greater extent than do higher rated securities, which react primarily to fluctuations in the general level of interest rates. High yield securities also tend to be more sensitive to economic conditions than are higher-rated securities. As a result, they generally involve more credit risks than securities in the higher-rated categories. During an economic downturn or a sustained period of rising interest rates, highly leveraged issuers of high yield securities may experience financial stress and may not have sufficient revenues to meet their payment obligations. The issuers of high yield securities are typically more leveraged, and the risk of loss due to default by an issuer of these securities is significantly greater than issuers of higher-rated securities because such securities are generally unsecured and are often subordinated to other creditors. Further, if the issuer of a high yield security defaulted, the Fund might incur additional expenses to seek recovery. Periods of economic uncertainty and changes would also generally result in increased volatility in the market prices of these securities and thus in the Fund’s net asset value.

Payment Expectations. High yield securities typically contain redemption, call, or prepayment provisions that permit the issuer of such securities containing such provisions to redeem the securities at its discretion. During periods of falling interest rates, issuers of these securities are likely to redeem or prepay the securities and refinance them with debt securities with a lower interest rate. To the extent an issuer is able to refinance the securities, or otherwise redeem them, the Fund may have to replace the securities with a lower yielding security, which could result in a lower yield and return for the Fund.

Credit Ratings. Credit ratings issued by credit-rating agencies evaluate the safety of principal and interest payments of rated securities. They do not, however, evaluate the market value risk of high yield securities and, therefore, may not fully reflect the true risks of an investment. In addition, credit rating agencies may or may not make timely changes in a rating to reflect changes in the economy or in the condition of the issuer that affect the market value of the security. Consequently, credit ratings are used only as a preliminary indicator of investment quality. Investments in high yield securities will be more dependent on the Adviser’s credit analysis than would be the case with investments in investment-grade debt securities. The Adviser employs its own credit research and analysis, which includes a study of existing debt, capital structure, ability to service debt and to pay dividends, the issuer’s sensitivity to economic conditions, its operating history, and the current trend of earnings. The Adviser continually monitors the investments of the Fund and carefully evaluates whether to dispose of or to retain high yield securities whose credit ratings or credit quality may have changed.

Liquidity and Valuation. The Fund may have difficulty disposing of certain high yield securities because there may be a thin trading market for such securities. Because not all dealers maintain markets in all high yield securities, there is no established retail secondary market for many of these securities. Such securities are sold only to a limited number of dealers or institutional investors. To the extent a secondary trading market does exist, it is generally not as liquid as the secondary market for higher-rated securities. The lack of a liquid secondary market may have an adverse impact on the market price of the security. The lack of a liquid secondary market for certain securities also may make it more difficult for the Fund to obtain accurate

B-21

Table of Contents

market quotations for purposes of valuing the Fund. Market quotations are generally available on many high yield issues only from a limited number of dealers and may not necessarily represent firm bids of such dealers or prices for actual sales. During periods of thin trading, the spread between bid and asked prices is likely to increase significantly. In addition, adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the values and liquidity of high yield securities, especially in a thinly traded market.

Lending of Portfolio Securities. In order to generate additional income, the Fund may lend portfolio securities. When the Fund lends portfolio securities, it will receive either cash or liquid securities as collateral from the borrower. The Fund will reinvest cash collateral in short-term liquid securities that qualify as an otherwise acceptable investment for the Fund. If the market value of the loaned securities increases, the borrower must furnish additional collateral to the Fund. During the time portfolio securities are on loan, the borrower pays the Fund any dividends or interest paid on such securities. Loans are subject to termination at the option of the Fund or the borrower. The lending Fund may pay reasonable administrative and custodial fees in connection with a loan and may pay a negotiated portion of the interest earned on the cash or equivalent collateral to a securities lending agent or broker. The Fund may lend its portfolio securities through BMO Harris Bank, as agent.

When the Fund lends its portfolio securities, it may not be able to get them back from the borrower on a timely basis, in which case the Fund may lose certain investment opportunities, as well as the opportunity to vote the securities. The Fund is also subject to the risks associated with the investments of cash collateral, usually fixed income securities risk. If the Fund receives a payment from a borrower in lieu of the dividends on the loaned securities, such payment will generally be taxed as ordinary income for federal income tax purposes and will not be treated as “qualified dividend income.”

Leverage Risks. Leverage risk is created when an investment exposes the Fund to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Fund’s risk of loss and potential for gain.

Municipal Securities are fixed income securities issued by states, counties, cities, and other political subdivisions and authorities. Although most municipal securities are exempt from regular federal income tax, municipalities also may issue securities subject to federal alternative minimum tax (AMT) and taxable securities. Tax-exempt securities are generally classified by their source of payment. The ability of a governmental issuer to make payments on its municipal obligations can be adversely affected by factors such as budget shortfalls, weak economic conditions, and reduced levels of aid to governments. Other uncertainties applicable to municipal securities may include legislation or litigation that changes the taxation of municipal securities or the rights of municipal security holders in the event of bankruptcy. Certain provisions of the U.S. Bankruptcy Code governing such bankruptcies are unclear, and the application of state law to municipal security issuers could provide varying results among the states or among the municipal security issuers within a state. These uncertainties could have a significant impact on the prices of the municipal securities in which the Fund invests.

General Obligation Bonds are supported by the issuer’s full faith and credit. The issuer must levy and collect taxes sufficient to pay principal and interest on the bonds. However, the issuer’s authority to levy additional taxes may be limited by its charter or state law.

Special Revenue Bonds are payable solely from specific revenues received by the issuer. The revenues may consist of specific taxes, assessments, tolls, fees, or other types of municipal revenues. For example, a municipality may issue bonds to build a toll road, and pledge the tolls to repay the bonds. Bondholders could not collect from the municipality’s general taxes or revenues. Therefore, any shortfall in the tolls normally would result in a default on the bonds.

Private Activity Bonds are special revenue bonds used to finance private entities. For example, a municipality may issue bonds to finance a new factory to improve its local economy. The municipality would lend the proceeds to the company using the factory, and the company would agree to make loan payments

B-22

Table of Contents

sufficient to repay the bonds. The bonds would be payable solely from the company’s loan payments, and not from any other revenues of the municipality. Therefore, any default on the loan normally would result in a default on the bonds.

The interest on many types of private activity bonds is subject to the federal AMT. The Fund may invest in bonds subject to the federal AMT.

Anticipation Notes are securities issued in anticipation of the receipt of taxes, grants, bond proceeds, or other municipal revenues. For example, many municipalities collect property taxes once a year. Such municipalities may issue tax anticipation notes to fund their operations prior to collecting these taxes. The issuers then repay the tax anticipation notes at the end of their fiscal year, either with collected taxes or proceeds from newly issued notes or bonds.

Tax Increment Financing Bonds are payable from increases in taxes or other revenues attributable to projects financed by the bonds. For example, a municipality may issue these bonds to redevelop a commercial area. The tax increment financing bonds would be payable solely from any increase in sales taxes collected from merchants in the area. The bonds could default if merchants’ sales, and related tax collections, failed to increase as anticipated.

Municipal Securities include:

Municipal Leases. The Fund may purchase participation interests that represent an undivided proportional interest in lease payments by a governmental or nonprofit entity. Lease obligations may be limited by a municipal charter or by the inclusion in leases or contracts of “non-appropriation” clauses that relieve governmental issuers of any obligation to make future payments under the lease or contract unless money is appropriated for such purpose by the appropriate legislative body. If the entity does not appropriate funds for future lease or contract payments, the entity cannot be compelled to make such payments. Furthermore, a lease may provide that the participants cannot accelerate lease obligations upon default. The participants would only be able to enforce lease payments as they became due. In the event of a default or failure of appropriation, it is unlikely that the participants would be able to obtain an acceptable substitute source of payment unless the participation interests are credit enhanced.

The Adviser must consider the following factors in determining the liquidity of municipal lease securities: (1) the frequency of trades and quotes for the security; (2) the volatility of quotations and trade prices for the security; (3) the number of dealers willing to purchase or sell the security and the number of potential purchasers;

B-23

Table of Contents

(4) dealer undertakings to make a market in the security; (5) the nature of the security and the nature of the marketplace trades; (6) the rating of the security and the financial condition and prospects of the issuer of the security; (7) such other factors as may be relevant to the Fund’s ability to dispose of the security; (8) whether the lease can be terminated by the lessee; (9) the potential recovery, if any, from a sale of the leased property upon termination of the lease; (10) the lessee’s general credit strength; (11) the likelihood that the lessee will discontinue appropriating funding for the leased property because the property is no longer deemed essential to its operations; and (12) any credit enhancement or legal recourse provided upon an event of non-appropriation or other termination of the lease.

Variable Rate Municipal Securities . Variable interest rates generally reduce changes in the market value of municipal securities from their original purchase prices. Accordingly, as interest rates decrease or increase, the potential for capital appreciation or depreciation is less for variable rate municipal securities than for fixed rate obligations. Many municipal securities with variable interest rates purchased by the Fund are subject to repayment of principal (usually within seven days) on the Fund’s demand. For purposes of determining the Fund’s average maturity, the maturities of these variable rate demand municipal securities (including participation interests) are the longer of the periods remaining until the next readjustment of their interest rates or the periods remaining until their principal amounts can be recovered by exercising the right to demand payment. The terms of these variable rate demand instruments require payment of principal and accrued interest from the issuer of the municipal obligations, the issuer of the participation interests or a guarantor of either issuer.

Repurchase Agreements and Reverse Repurchase Agreements. A repurchase agreement is a transaction in which the Fund buys a security from a dealer or bank and agrees to sell the security back at a mutually agreed upon time and price. The repurchase price exceeds the sale price, reflecting an agreed upon interest rate effective for the period the buyer owns the security subject to repurchase. The agreed upon interest rate is unrelated to the interest rate on that security. The Adviser will continually monitor the value of the underlying security to ensure that the value of the security always equals or exceeds the repurchase price. The Fund’s custodian is required to take possession of the securities subject to repurchase agreements. These securities are marked to market daily. To the extent that the original seller defaults and does not repurchase the securities from the Fund, the Fund could receive less than the repurchase price for such securities. In the event that such a defaulting seller files for bankruptcy or becomes insolvent, disposition of such securities by the Fund might be delayed pending court action. The Fund believes that, under the procedures normally in effect for custody of the portfolio securities subject to repurchase agreements, a court of competent jurisdiction would rule in favor of the Fund and allow retention or disposition of such securities. The Fund will only enter into repurchase agreements with banks and other recognized financial institutions, such as broker/dealers, that the Adviser has determined to be creditworthy.

Reverse repurchase agreement transactions are similar to borrowing cash. In a reverse repurchase agreement, the Fund sells a portfolio security to another person, such as a financial institution, broker or dealer, in return for a percentage of the instrument’s market value in cash, and agrees that on a stipulated date in the future the Fund will repurchase the portfolio security at a price equal to the original sale price plus interest. The Fund may use reverse repurchase agreements for liquidity and for avoiding a sale of portfolio instruments at a time when the sale may be deemed disadvantageous.

When effecting reverse repurchase agreements, liquid assets of the Fund, in a dollar amount sufficient to make payment for the obligations to be purchased, are segregated on the trade date. These securities are marked to market daily and maintained until the transaction is settled.

Risks Related to Company Size. Generally, the smaller the market capitalization of a company, the fewer the number of shares traded daily, the less liquid its stock, and the more volatile its price. Market capitalization is determined by multiplying the number of the company’s outstanding shares by its current market price per share.

B-24

Table of Contents

Companies with smaller market capitalizations also tend to have unproven track records, a limited product or service base, and limited access to capital. These factors also increase risks and make these companies more likely to fail than companies with larger market capitalizations.

Securities of Other Investment Companies. The Fund may invest in the securities of other investment companies, including affiliated BMO Funds and exchange-traded funds, within the limits prescribed by the 1940 Act and the rules promulgated thereunder. Investments in the securities of other investment companies may involve duplication of advisory fees and certain other expenses. By investing in another investment company, the Fund becomes a shareholder of that investment company. As a result, Fund shareholders indirectly will bear the Fund’s proportionate share of the fees and expenses paid by shareholders of the other investment company, in addition to the fees and expenses Fund shareholders directly bear in connection with the Fund’s own operations. The Fund also may invest in investment companies that are not organized under the laws of the United States (Offshore Funds). In addition to the risks of investing in securities of other investment companies, Offshore Funds are also subject to the risks described under “Foreign Securities,” above.

Sovereign Debt. The Fund may purchase sovereign debt. Sovereign debt differs from debt obligations issued by private entities in that, generally, remedies for defaults must be pursued in the courts of the defaulting party. Legal recourse is therefore limited. Political conditions, especially a sovereign entity’s willingness to meet the terms of its debt obligations, are of considerable significance. Also, there can be no assurance that the holders of commercial bank loans to the same sovereign entity may not contest payments to the holders of sovereign debt in the event of default under commercial bank loan agreements. Financial markets have recently experienced increased volatility due to the uncertainty surrounding the sovereign debt of certain European countries, which may have significant adverse effects on the economies of these countries and increase the risks of investing in sovereign debt.

A sovereign debtor’s willingness or ability to repay principal and pay interest in a timely manner may be affected by a variety of factors, including among others, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the sovereign debtor’s policy toward principal international lenders, and the political constraints to which a sovereign debtor may be subject. A country whose exports are concentrated in a few commodities could be vulnerable to a decline in the international price of such commodities. Increased protectionism on the part of a country’s trading partners, or political changes in those countries, could also adversely affect its exports. Such events could diminish a country’s trade account surplus, if any, or the credit standing of a particular local government or agency. Another factor bearing on the ability of a country to repay sovereign debt is the level of the country’s international reserves. Fluctuations in the level of these reserves can affect the amount of foreign exchange readily available for external debt payments and, thus, could have a bearing on the capacity of the country to make payments on its sovereign debt.

To the extent that a country has a current account deficit (generally when its exports of merchandise and services are less than its country’s imports of merchandise and services plus net transfers (e.g., gifts of currency and goods) to foreigners), it may need to depend on loans from foreign governments, multilateral organizations or private commercial banks, aid payments from foreign governments, and inflows of foreign investment. The access of a country to these forms of external funding may not be certain and a withdrawal of external funding could adversely affect the capacity of a government to make payments on its obligations. In addition, the cost of servicing debt obligations can be adversely affected by a change in international interest rates, since the majority of these obligations carry interest rates that are adjusted periodically based upon international rates.

With respect to sovereign debt of emerging market issuers, investors should be aware that certain emerging market countries are among the largest debtors to commercial banks and foreign governments. At times, certain emerging market countries have declared moratoria on the payment of principal and interest on external debt.

Certain emerging market countries have experienced difficulty in servicing their sovereign debt on a timely basis, which led to defaults on certain obligations and the restructuring of certain indebtedness. Restructuring

B-25

Table of Contents

arrangements have included, among other things, reducing and rescheduling interest and principal payments by negotiating new or amended credit agreements or converting outstanding principal and unpaid interest to Brady Bonds (discussed below), and obtaining new credit to finance interest payments. Holders of sovereign debt, including the Fund, may be requested to participate in the rescheduling of such debt and to extend further loans to sovereign debtors, and the interests of holders of sovereign debt could be adversely affected in the course of restructuring arrangements or by certain other factors referred to below. Furthermore, some of the participants in the secondary market for sovereign debt also may be directly involved in negotiating the terms of these arrangements and may therefore have access to information not available to other market participants, such as the Fund. Obligations arising from past restructuring agreements may affect the economic performance and political and social stability of certain issuers of sovereign debt. There is no bankruptcy proceeding by which sovereign debt on which a sovereign has defaulted may be collected in whole or in part.

Foreign investment in certain sovereign debt is restricted or controlled to varying degrees. These restrictions or controls may at times limit or preclude foreign investment in such sovereign debt and increase the costs and expenses of the Fund. Certain countries in which the Fund may invest require governmental approval prior to investments by foreign persons, limit the amount of investment by foreign persons in a particular issuer, limit the investment by foreign persons only to a specific class of securities of an issuer that may have less advantageous rights than the classes available for purchase by domiciliaries of the countries or impose additional taxes on foreign investors. Certain issuers may require governmental approval for the repatriation of investment income, capital, or the proceeds of sales of securities by foreign investors. In addition, if a deterioration occurs in a country’s balance of payments, the country could impose temporary restrictions on foreign capital remittances. The Fund could be adversely affected by delays in, or a refusal to grant, any required governmental approval for repatriation of capital, as well as by the application to the Fund of any restrictions on investments. Investing in local markets may require the Fund to adopt special procedures, seek local government approvals, or take other actions, each of which may involve additional costs to the Fund.

The sovereign debt in which the Fund may invest includes Brady Bonds, which are securities created through the exchange of existing commercial bank loans to public and private entities in certain emerging markets for new bonds in connection with debt restructurings under a debt restructuring plan introduced by former U.S. Secretary of the Treasury, Nicholas F. Brady. Brady Bonds may be collateralized or uncollateralized and are issued in various currencies (but primarily the dollar). Dollar-denominated, collateralized Brady Bonds, which may be fixed-rate bonds or floating-rate bonds, are generally collateralized in full as to principal by U.S. Treasury zero coupon bonds having the same maturity as the Brady Bonds. Interest payments on these Brady Bonds generally are collateralized by cash or securities in an amount that, in the case of fixed rate bonds, is equal to at least one year of rolling interest payments or, in the case of floating rate bonds, initially is equal to at least one year’s rolling interest payments based on the applicable interest rate at that time and is adjusted at regular intervals thereafter. Brady Bonds are often viewed as having several valuation components: (1) the collateralized repayment of principal, if any, at final maturity, (2) the collateralized interest payments, if any, (3) the uncollateralized interest payments, and (4) any uncollateralized repayment of principal at maturity (these uncollateralized amounts constitute the “residual risk”). In light of the residual risk of Brady Bonds and, among other factors, the history of defaults with respect to commercial bank loans by public and private entities of countries issuing Brady Bonds, investments in Brady Bonds have speculative characteristics. The Fund may purchase Brady Bonds with no or limited collateralization, and will be relying for payment of interest and (except in the case of principal collateralized Brady Bonds) principal primarily on the willingness and ability of the foreign government to make payment in accordance with the terms of the Brady Bonds.

Temporary Investments . There may be times when market conditions warrant a defensive position. During these market conditions, the Fund may temporarily invest without limit in short-term debt obligations (money market instruments). These investments may include commercial paper, bank instruments, U.S. government obligations, repurchase agreements, securities of other investment companies investing in short-term debt securities, and foreign short-term debt securities. The Fund’s temporary investments must be of comparable quality to their primary investments.

B-26

Table of Contents

U.S. Government Securities . U.S. government securities include direct obligations of the U.S. government, including U.S. Treasury bills, notes, and bonds of varying maturities, and those issued or guaranteed by various U.S. government agencies and instrumentalities. Treasury securities are direct obligations of the federal government of the United States. Agency securities are issued or guaranteed by a federal agency or other government sponsored entity acting under federal authority. Some government entities are supported by the full faith and credit of the United States. Other government entities receive support through federal subsidies, loans, or other benefits. A few government entities have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

The Fund treats mortgage-backed securities guaranteed by a government sponsored entity as if issued or guaranteed by a federal agency. Although such a guarantee protects against credit risks, it does not reduce the market and prepayment risks.

Federal National Mortgage Association (Fannie Mae) and Federal Home Loan Mortgage Corporation (Freddie Mac). Fannie Mae and Freddie Mac were placed into conservatorship by the Federal Housing Finance Agency (FHFA), an independent regulator, in 2008, and FHFA succeeded to all of their rights, titles, powers, and privileges. At the time Fannie Mae and Freddie Mac were placed in conservatorship, the U.S. Treasury established preferred stock purchase agreements pursuant to which the U.S. Treasury will contribute cash capital to maintain a positive net worth in each enterprise. These agreements were amended in December 2009 to permit the U.S. Treasury’s funding commitment to increase as necessary to accommodate any cumulative reduction in net worth of the enterprises for a three-year period. FHFA has the right to transfer or sell any asset or liability of Fannie Mae or Freddie Mac without any approval, assignment or consent, although FHFA has stated that it has no present intention to do so. In addition, holders of mortgage-backed securities issued by Fannie Mae or Freddie Mac may not enforce certain rights related to such securities against FHFA, or the enforcement of such rights may be delayed, during the conservatorship.

When-Issued and Delayed Delivery Transactions . These transactions are made to secure what is considered to be an advantageous price or yield. Settlement dates may be a month or more after entering into these transactions and the market values of the securities purchased may vary from the purchase prices. Other than normal transaction costs, no fees or expenses are incurred. However, liquid assets of the Fund are segregated on the Fund’s records on the trade date in an amount sufficient to make payment for the securities to be purchased. These assets are marked to market daily and are maintained until the transaction has been settled.

Zero Coupon Securities. Zero coupon securities in which the Fund may invest do not pay interest or principal until final maturity, unlike debt securities that provide periodic payments of interest (referred to as a “coupon payment”). Investors buy zero coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate and credit risks of a zero coupon security. An investment in zero coupon securities may cause the Fund to recognize income and make distributions to shareholders before it receives any cash payments on its investment. The Fund may have to dispose of its portfolio investments under disadvantageous circumstances to generate sufficient cash to satisfy the distribution requirements for maintaining the Fund’s status as an RIC.

Short Sales. The Fund, including any underlying funds in which the Fund may invest, may sell securities, including shares of exchange-traded funds, short in anticipation of a decline in the market value of the securities. When the Fund sells a security short, the Fund does not own the security and must borrow the security to make delivery to the buyer. The Fund must then replace the borrowed security by purchasing it at the market price at the time of replacement, which may be more or less than the price at which the Fund sold the security. Any potential gain is limited to the price at which the Fund sold the security short, and any potential loss is unlimited in size. Until the Fund closes its short position or replaces the borrowed security, the Fund will designate liquid assets it owns (other than the short sale proceeds) as segregated assets in an amount equal to its obligation to

A high rate of portfolio turnover (over 100%) may involve correspondingly greater transaction costs to the Fund and its shareholders. High portfolio turnover may result in the realization of substantial capital gains, including short-term capital gains taxable to shareholders at ordinary income rates.
