INVESTMENT INSTRUMENTS AND POLICIES

The following supplements the information contained in the Prospectus concerning the investment objective and policies of the Fund.

The Fund seeks a high level of current income consistent with the preservation of principal and liquidity. While the Fund is not a money market fund, it will seek to maintain a stable $1.00 net asset value (“NAV”) per share. Normally, the Fund will invest at least 80% of its net assets (including borrowings for investment purposes) in investment grade fixed and floating rate securities that are denominated solely in U.S. dollars. These instruments may include repurchase agreements, negotiable certificates of deposit, commercial paper, letters of credit of banking institutions, time deposits, bankers acceptances, money market mutual funds, corporate debt obligations, asset-backed securities, mortgage-backed securities and municipal securities. The Fund may invest in foreign securities that are denominated in U.S. dollars including corporate, supranational, sovereign and bank debt obligations. The Fund may also invest in securities issued by the U.S. Government, its agencies, instrumentalities, or sponsored enterprises. Instruments that are fully collateralized by securities listed above and additional instruments approved by the Company’s Board of Directors are also permissible.

The Fund may also use certain derivatives such as futures, swaps and options. The Fund will use derivatives to adjust the Fund’s average maturity, particularly when the Fund receives new investments or redemption requests; manage or reduce the Fund’s exposure to risks, primarily interest rate risk; and/or generate additional return for the Fund (which may be considered speculative).

The Adviser might not invest in all of the instruments or use all of the investment techniques permitted by the Fund’s Prospectus and this SAI or invest in such instruments or engage in such techniques to the full extent permitted by the Fund’s investment policies and limitations.

The Fund will attempt to limit share volatility by maintaining a weighted average maturity of 365 days or less and limiting maturity of individual instruments in the Fund’s portfolio to 36 months. The Fund’s portfolio holdings disclosures will reflect each instrument’s stated legal final maturity of some instruments, which will be longer than 36 months for many of the holdings in the Fund.

The Adviser measures “maturity” as follows:

The Adviser considers the following factors when evaluating the maturity of a debt instrument:

Floating Rate Instruments. These debt instruments are obligated to pay an interest rate to investors that resets on a regular interval typically based on a short-term interest rate index, such as the London Interbank Offering Rate (“LIBOR”) or a U.S. Treasury Bill Index. Generally, coupons will reset on either a monthly (30 days) or quarterly (90 days) basis. Interest rate risk is diminished and the maximum exposure to interest rate risk is the spread in time between reset dates. The market prices of these instruments will generally be at or close to par at all times. This feature provides for stable market prices and is the main factor in determining maturity.

Weighted Average Life (“WAL”). WAL is a metric applied to amortizing instruments. What distinguishes an amortizing security from a non-amortizing security is the inclusion of principal in scheduled cash flows. The majority of these instruments are mortgage-backed securities (“MBS”) and asset-backed securities (“ABS”) backed by various types and/or pools of many loans with similar features. Principal repayments occur at regular intervals, typically monthly for most MBS/ABS or on an ad-hoc basis which means one or many of the pools of loans within the MBS/ABS completely returned principal ahead of scheduled maturity. WAL is a more accurate and relevant measure of maturity because a portion of the principal has already been returned to investors. The Adviser believes that WAL specifically measures the average unpaid principal balance remaining outstanding denominated in years. The market values these instruments relative to WAL versus the final stated maturity. For most amortizing instruments, WAL will always be less than final maturity. Thus, risk is more calibrated to WAL versus final maturity.

Put Feature. A put feature embedded within a debt instrument gives the investor the option to put the security back to the issuer ahead of stated maturity at either par value or a stated price slightly different than par. The put option has a specific date when this feature can be triggered at the option of the debt holder. Because the holder of this security can request principal payment ahead of maturity, values of these instruments are calibrated to the put date instead of final maturity.

Bank Obligations. The Fund may invest in obligations issued or guaranteed by U.S. or foreign banks. Bank obligations, including without limitation, time deposits, bankers’ acceptances, letters of credit and certificates of deposit, may be general obligations of the parent bank or may be limited to the issuing branch by the terms of the specific obligations or by government regulations.

Banks are subject to extensive but different governmental regulations which may limit both the amount and types of loans which may be made and interest rates which may be charged. In addition, the profitability of the banking industry is largely dependent upon the availability and cost of funds for the purpose of financing lending operations under prevailing money market conditions. General economic conditions as well as exposure to credit losses arising from possible financial difficulties of borrowers play an important part in the operation of this industry.

Corporate Debt Obligations. The Fund may invest in corporate debt obligations, including obligations of industrial, utility and financial issuers. Corporate debt obligations include bonds, notes, debentures and other obligations of corporations to pay interest and repay principal. Corporate debt obligations are subject to the risk of an issuer’s inability to meet principal and interest payments on the obligations and may also be subject to price volatility due to such factors as market interest rates, market perception of the creditworthiness of the issuer and general market liquidity.

Commercial Paper and Other Short-Term Corporate Obligations. The Fund may invest in commercial paper and other short-term obligations payable in U.S. dollars and issued or guaranteed by U.S. corporations, non-U.S. corporations or other entities. Commercial paper represents short-term unsecured promissory notes issued in bearer form by banks or bank holding companies, corporations and finance companies.

Variable and Floating Rate Obligations. The interest rates payable on certain securities in which the Fund may invest are not fixed and may fluctuate based upon changes in market rates. A variable rate obligation has an interest rate which is adjusted at pre-designated periods in response to changes in the market rate of interest on which the interest rate is based. Variable and floating rate obligations are less effective than fixed rate instruments at locking in a particular yield. Nevertheless, such obligations may fluctuate in value in response to interest rate changes if there is a delay between changes in market interest rates and the interest reset date for the obligation.

Repurchase Agreements. Repurchase agreements involve the purchase of securities subject to the seller’s agreement to repurchase them at a mutually agreed upon date and price.

- 3 -

Table of Contents

The repurchase price under a repurchase agreement generally equals the price paid by the Fund plus interest negotiated on the basis of current short-term rates (which may be more or less than the rate on the securities underlying the repurchase agreement). The Fund may enter into repurchase agreements with counterparties that the Adviser considers creditworthy pursuant to criteria approved by the Board of Directors. The Adviser will consider the creditworthiness of a seller in determining whether to have the Fund enter into a repurchase agreement. The seller under a repurchase agreement will be required to maintain the value of the securities subject to the agreement at not less than the repurchase price plus accrued interest. The Adviser will mark to market daily the value of the securities, and will, if necessary, require the seller to maintain additional securities, to ensure that the value is not less than the repurchase price.

Default by or bankruptcy of the seller would, however, expose the Fund to possible loss because of adverse market action or delays in connection with the disposition of the underlying obligations.

Reverse Repurchase Agreements. The Fund may borrow money by entering into transactions called reverse repurchase agreements. Under these arrangements, the Fund will sell portfolio securities with an agreement to repurchase the security on an agreed date, price and interest payment. Reverse repurchase agreements involve the possible risk that the value of portfolio securities the Fund relinquishes may decline below the price the Fund must pay when the transaction closes. Borrowings may magnify the potential for gain or loss on amounts invested resulting in an increase in the speculative character of the Fund’s outstanding shares.

When the Fund enters into a reverse repurchase agreement, it places in a separate custodial account either liquid assets or other high grade debt securities that have a value equal to or greater than the repurchase price. The account is monitored to make sure that an appropriate value is maintained. Reverse repurchase agreements are considered to be borrowings under the 1940 Act.

Mortgage-Backed Securities. The Fund may invest in mortgage-backed securities. Mortgage-backed securities represent direct or indirect participations in, or are collateralized by and payable from, mortgage loans secured by real property. Mortgage-backed securities can be backed by either fixed rate mortgage loans or adjustable rate mortgage loans, and may be issued by either a governmental or non-governmental entity.

The Fund may invest in privately-issued mortgage securities that represent interests in pools of mortgage loans that are issued by trusts formed by originators of and institutional investors in mortgage loans (or represent interests in custodial arrangements administered by such institutions). These originators and institutions include commercial banks, savings and loan associations, credit unions, savings banks, mortgage bankers, insurance companies, investment banks or special purpose subsidiaries of the foregoing. The pools underlying privately-issued mortgage pass-through securities consist of mortgage loans secured by mortgages or deeds of trust creating a lien on commercial, residential, residential multi-family and mixed residential/commercial properties. These mortgage-backed securities typically do not have the same credit standing as U.S. government guaranteed mortgage-backed securities.

Table of Contents

Privately-issued mortgage securities generally offer a higher yield than similar securities issued by a government entity because of the absence of any direct or indirect government or agency payment guarantees. However, timely payment of interest and principal on mortgage loans in theses pools may be supported by various forms of insurance or guarantees, including individual loan, pool and hazard insurance, subordination and letters of credit. The insurance and guarantees are issued by government entities, private insurers, banks and mortgage poolers. Mortgage-backed securities without insurance or guarantees may also be purchased by the Fund if they have the required rating from an NRSRO.

Mortgage-backed securities may include multiple class securities, including collateralized mortgage obligations (“CMOs”) and real estate mortgage investment conduit (“REMIC”) pass-through or participation certificates. A REMIC is a CMO that qualifies for special tax treatment under the Internal Revenue Code of 1986, as amended (the “Code”) and invests in certain mortgages principally secured by interests in real property and other permitted investments. CMOs provide an investor with a specified interest in the cash flow from a pool of underlying mortgages or of other mortgage-backed securities. CMOs are issued in multiple classes each with a specified fixed or floating interest rate and a final scheduled distribution date. In many cases, payments of principal are applied to the CMO classes in the order of their respective stated maturities, so that no principal payments will be made on a CMO class until all other classes having an earlier stated maturity date are paid in full.

To the extent the Fund concentrates its investments in pools of mortgage-backed securities sponsored by the same sponsor or serviced by the same servicer, it may be subject to additional risks. Servicers of mortgage-related pools collect payments on the underlying mortgage assets for pass-through to the pool on a periodic basis. Upon insolvency of the servicer, the pool may be at risk with respect to collections received by the servicer but not yet delivered to the pool.

Asset-Backed Securities. Asset-backed securities are securities whose principal and interest payments are collateralized by pools of assets including, but not limited to, auto loans, credit card receivables, leases, installment contracts, student loans and personal property. Asset-backed securities are often subject to more rapid repayment than their stated maturity date would indicate as a result of the pass-through of prepayments of principal on the underlying loans. During periods of declining interest rates, prepayment of loans underlying asset-backed securities can be expected to accelerate. Accordingly, the Fund’s ability to maintain positions in such securities will be affected by reductions in the principal amount of such securities resulting from prepayments, and its ability to reinvest the returns of principal at comparable yields is subject to generally prevailing interest rates at that time. Asset-backed securities present credit risks that are not presented by mortgage-backed securities. This is because asset-backed securities generally do not have the benefit of a security interest in collateral that is comparable to mortgage assets. If the issuer of an asset-backed security defaults on its payment obligations, there is the possibility that, in some cases, the Fund will be unable to possess and sell the underlying collateral and that the Fund’s recoveries on repossessed collateral may not be available to support payments on the securities. In the event of a default, the fund may suffer a loss if it cannot sell collateral quickly and receive the amount it is owed.

Municipal Securities. The Fund may invest in securities and instruments issued by state and local government issuers. Municipal securities consist of bonds, notes, commercial paper and

- 5 -

Table of Contents

other instruments (including participation interests in such securities) issued by or on behalf of the states, territories and possessions of the United States (including the District of Columbia) and their political subdivisions, agencies or instrumentalities.

Municipal securities include both “general” and “revenue” bonds and may be issued to obtain funds for various purposes. General obligations are secured by the issuer’s pledge of its full faith, credit and taxing power. Revenue obligations are payable only from the revenues derived from a particular facility or class of facilities.

Municipal securities are often issued to obtain funds for various public purposes, including the construction of a wide range of public facilities such as bridges, highways, housing, hospitals, mass transportation, schools, streets and water and sewer works. Municipal securities include private activity bonds, pre-refunded municipal securities and auction rate securities.

The obligations of the issuer to pay the principal of and interest on a municipal security are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Act, and laws, if any, that may be enacted by Congress or state legislatures extending the time for payment of principal or interest or imposing other constraints upon the enforcement of such obligations. There is also the possibility that, as a result of litigation or other conditions, the power or ability of the issuer to pay when due the principal of or interest on a municipal security may be materially affected.

In addition, municipal securities include municipal leases, certificates of participation and “moral obligation” bonds. A municipal lease is an obligation issued by a state or local government to acquire equipment or facilities. Certificates of participation represent interests in municipal leases or other instruments, such as installment purchase agreements. Moral obligation bonds are supported by a moral commitment but not a legal obligation of a state or local government. Municipal leases, certificates of participation and moral obligation bonds frequently involve special risks not normally associated with general obligation or revenue bonds. In particular, these instruments permit governmental issuers to acquire property and equipment without meeting constitutional and statutory requirements for the issuance of debt. If, however, the governmental issuer does not periodically appropriate money to enable it to meet its payment obligations under these instruments, it cannot be legally compelled to do so. If a default occurs, it is likely that the Fund would be unable to obtain another acceptable source of payment. Some municipal leases, certificates of participation and moral obligation bonds may be illiquid.

Municipal securities may also be in the form of a tender option bond, which is a municipal security (generally held pursuant to a custodial arrangement) having a relatively long maturity and bearing interest at a fixed rate substantially higher than prevailing short-term, tax-exempt rates. The bond is typically issued with the agreement of a third party, such as a bank, broker-dealer or other financial institution, which grants the security holders the option, at periodic intervals, to tender their securities to the institution. After payment of a fee to the financial institution that provides this option, the security holder effectively holds a demand obligation that bears interest at the prevailing short-term, tax-exempt rate. An institution may not be obligated to accept tendered bonds in the event of certain defaults or a significant downgrading in the credit rating assigned to the issuer of the bond. The tender option will be taken into account in determining the maturity of the tender option bonds and the Fund’s duration. Certain tender option bonds may be illiquid.

Table of Contents

Municipal securities may be backed by letters of credit or other forms of credit enhancement issued by domestic or foreign banks or by other financial institutions. The credit quality of these banks and financial institutions could, therefore, cause a loss to the Fund. Letters of credit and other obligations of foreign banks and financial institutions may involve risks in addition to those of domestic obligations because of less publicly available financial and other information, less securities regulation, potential imposition of foreign withholding and other taxes, war, expropriation or other adverse governmental actions. Foreign banks and their foreign branches are not regulated by U.S. banking authorities, and are generally not bound by the accounting, auditing and financial reporting standards applicable to U.S. banks.

U.S. Government Obligations. The Fund may purchase U.S. Government securities. Some U.S. Government securities (such as U.S. Treasury bills, notes and bonds) are supported by the full faith and credit of the United States. Others, such as obligations issued or guaranteed by U.S. Government agencies, instrumentalities or sponsored enterprises are supported by: (a) the ability of the issuer to borrow, provided approval is granted, from the U.S. Treasury; (b) the discretionary authority of the U.S. Government to purchase certain obligations of the issuer; or (c) only the credit of the agency or instrumentality issuing the obligation. Such guarantees of U.S. Government securities held by the Fund do not, however, guarantee the market value of the shares of the Fund. There is no guarantee that the U.S. Government will continue to provide support to its agencies or instrumentalities in the future. U.S. Government securities that are not backed by the full faith and credit of the U.S. Government are subject to greater risks than those that are backed by the full faith and credit of the U.S. Government. All U.S. Government securities are subject to interest rate risk.

U.S. Treasury securities include the separately traded principal and interest components of securities guaranteed or issued by the U.S. Treasury that are traded independently under the separate trading of registered interest and principal of securities program (“STRIPS”).

U.S. Treasury securities also include Treasury Inflation Protected Securities (“TIPS”) whose principal increases at the same rate as the Consumer Price Index (CPI). The interest payment is then calculated off of that inflated principal and repaid at maturity.

Foreign Securities. The Fund may invest in U.S. dollar denominated foreign securities, including corporate, supranational, sovereign and bank debt obligations. Investment in these securities involves risks which may include unfavorable political and economic developments, possible withholding taxes, seizure of foreign deposits, currency controls or other governmental restrictions which might affect payment of principal or interest. Furthermore, foreign companies are not regulated by U.S. authorities and are generally not bound by financial reporting standards comparable to U.S. standards.

Investment Company Securities. The Fund may invest in securities issued by other investment companies to the extent permitted by the 1940 Act and rules and regulations thereunder. Investments in the securities of other investment companies will involve duplication of advisory fees and certain other expenses.

Table of Contents

When-Issued Purchases and Forward Commitments. To the extent consistent with its investment objective, the Fund may purchase securities on a when-issued basis or purchase or sell securities on a forward commitment basis. When the Fund agrees to purchase securities on a when-issued basis or to purchase or sell securities on a forward commitment basis, the custodian will set aside cash, U.S. Government securities or other liquid assets equal to the amount of the purchase or the commitment in a separate account. The market value of the separate account will be monitored and if such market value declines, the Fund will subsequently be required to place additional assets in the separate account in order to ensure that the value of the account remains equal to the amount of the Fund’s commitments.

The value of the securities underlying a when-issued purchase or a forward commitment to purchase securities, and any subsequent fluctuations in their value, is taken into account when determining the Fund’s net asset value (“NAV”) starting on the day that the Fund agrees to purchase the securities. The Fund does not earn interest on the securities committed to purchase until the securities are paid for and delivered on the settlement date. When the Fund makes a forward commitment to sell securities, the proceeds to be received upon settlement are included in the Fund’s assets, and fluctuations in the value of the underlying securities are not reflected in the Fund’s NAV as long as the commitment remains in effect.

Custodial Receipts. The Fund may invest in custodial receipts in respect of securities issued or guaranteed as to principal and interest by the U.S. Government, its agencies, instrumentalities, sponsored enterprises, political subdivisions or authorities. Such custodial receipts evidence ownership of future interest payments, principal payments or both on certain notes or bonds issued or guaranteed as to principal and interest by the U.S. Government, its agencies, instrumentalities, sponsored enterprises, political subdivisions or authorities. These custodial receipts are known by various names, including “Treasury Receipts,” “Treasury Investors Growth Receipts” (“TIGRs”) and “Certificates of Accrual on Treasury Securities” (“CATs”). For certain securities law purposes, custodial receipts are not considered U.S. Government securities.

Borrowing. The Adviser intends to borrow for leverage or for temporary or emergency purposes, including to meet portfolio redemption requests so as to permit the orderly disposition of portfolio securities, or to facilitate settlement transactions on portfolio securities. The Fund must maintain asset coverage of at least 300% of the amounts borrowed. Although the principal of such borrowings will be fixed, the Fund’s assets may change in value during the time the borrowing is outstanding. The Fund expects that some of its borrowings may be made on a secured basis. In such situations, either the custodian will segregate the pledged assets for the benefit of the lender or arrangements will be made with a suitable subcustodian, which may include the lender. If the securities held by the Fund should decline in value while borrowings are outstanding, the NAV of the Fund’s outstanding shares will decline in value by proportionately more than the decline in value suffered by the Fund’s securities. As a result, the Fund’s share price may be subject to greater fluctuation until the borrowing is paid off. The Fund’s short sales against the box and related borrowing are not subject to the restrictions outlined above.

Restricted and Illiquid Securities. The Fund does not intend to invest more than 15% of its net assets in illiquid securities, which are securities that the Adviser believes cannot be disposed of in seven days in the ordinary course of business at the approximate value at which the Fund has valued the securities. Any security can become illiquid at any time, but generally illiquid securities could include (but are not limited to): securities that are not readily marketable; repurchase agreements and other agreements with a notice or demand period of more than seven days; securities for which there is no secondary market; certain structured securities and certain swap transactions; certain over the counter options such as interest rate caps, floors and collars; and certain privately-placed securities that the Adviser determines are illiquid, based on its review of the trading markets for a specific restricted security. Securities that have legal or contractual restrictions on resale but have a readily available market are not considered illiquid for purposes of this limitation. Repurchase agreements subject to demand are deemed to have a maturity equal to the notice period.

The Fund may purchase securities which are not registered under the Securities Act of 1933, as amended (the “1933 Act”) but which may be sold to “qualified institutional buyers” in accordance with Rule 144A under the 1933 Act (“Rule 144A Securities”). These Rule 144A Securities will not be considered illiquid if the Adviser determines that an adequate trading market exists for the securities. As a result, the Fund could hold more illiquid securities during any period in which qualified institutional buyers become uninterested in purchasing Rule 144A Securities. The only types of restricted securities in which the Fund intends to invest are Rule 144A Securities that the Adviser has determined are not illiquid.

Normally, Rule 144A Securities are purchased and valued at a discount from the price at which such securities trade when they are not restricted, because the restriction makes them less liquid. The amount of the discount from the prevailing market price is expected to vary depending upon the type of security, the character of the issuer, the party who will bear the expenses of registering the Rule 144A Securities, and prevailing supply and demand conditions.

Mutual funds do not typically hold a significant amount of restricted or other illiquid securities because of the potential for delays on resale and uncertainty in valuation. Limitations on resale may adversely affect the marketability of portfolio securities and a mutual fund might be unable to dispose of restricted or other illiquid securities promptly or at reasonable prices and might thereby experience difficulty in satisfying redemptions within seven days. A mutual fund might also have to register such restricted securities in order to dispose of them resulting in additional expense and delay. Adverse market conditions could impede such a public offering of securities.

The Board of Directors has delegated to the Adviser the daily function of determining and monitoring the liquidity of the Fund’s securities in accordance with procedures adopted by the Board. The Board exercises its oversight responsibility for liquidity and remains responsible for liquidity determinations.

Table of Contents

Securities Lending. The Fund may lend its portfolio securities to financial institutions in accordance with the investment restrictions described below. Such loans would involve risks of delay in receiving additional collateral in the event the value of the collateral decreased below the value of the securities loaned or of delay in recovering the securities loaned or even loss of rights in the collateral should the borrower of the securities fail financially. However, loans will be made only to borrowers deemed by the Adviser to be of good standing and only when, in the Adviser’s judgment, the income to be earned from the loans justifies the attendant risks. Any loans of the Fund’s securities will be fully collateralized and marked to market daily.

Futures Contracts and Options on Futures Contracts. A futures contract may generally be described as an agreement between two parties to buy and sell particular financial instruments for an agreed price during a designated month (or to deliver the final cash settlement price, in the case of a contract not calling for physical delivery at the end of trading in the contract). When interest rates are rising or securities prices are falling, the Fund can seek to offset a decline in the value of its current portfolio securities through the sale of futures contracts. When interest rates are falling or securities prices are rising, the Fund, through the purchase of futures contracts, can attempt to secure better rates or prices than might later be available in the market when it effects anticipated purchases.

The Fund may purchase and sell Federal Funds, Eurodollar and Treasury futures contracts, and purchase and write call and put options on any of such futures contracts to seek to increase total return or to hedge against changes in interest rates, securities prices or to otherwise manage its term structure, sector selections and duration. The Fund may also enter into closing purchase and sale transactions with respect to any of such contracts and options. Federal Funds futures contracts are futures contracts based on the simple average of the daily effective federal funds rate during the month of the contract. The effective federal funds rate is a weighted average of all federal funds transactions for a group of federal funds brokers who report to the Federal Reserve Bank of New York each day. Eurodollar futures contracts are U.S. dollar-denominated futures contracts that are based on the implied forward LIBOR of a three-month deposit. Treasury futures are futures contracts to buy or sell the underlying Treasury securities of various maturities. The Fund will engage in futures and related options transactions for bona fide hedging purposes as described below or for purposes of seeking to increase total return, in each case, only to the extent permitted by regulations of the Commodity Futures Trading Commission (“CFTC”). All futures contracts entered into by the Fund are traded on U.S. exchanges.

Positions taken in the futures markets are not normally held to maturity but are instead liquidated through offsetting transactions, which may result in a profit or a loss. While futures contracts on securities will usually be liquidated in this manner, the Fund may instead make, or take, delivery of the underlying securities or currency whenever it appears economically advantageous to do so. A clearing corporation associated with the exchange on which futures on securities are traded guarantees that, if still open, the sale or purchase will be performed on the settlement date.

Hedging, by use of futures contracts, seeks to establish with more certainty than would otherwise be possible the effective price or rate of return on portfolio securities or securities that

- 10 -

Table of Contents

the Fund proposes to acquire. The Fund may, for example, take a “short” position in the futures market by selling futures contracts to seek to hedge against an anticipated rise in interest rates or a decline in market prices that would adversely affect the value of the Fund’s securities. Such futures contracts may include contracts for the future delivery of securities held by the Fund or securities with characteristics similar to those of the Fund’s securities. If, in the opinion of the Adviser, there is a sufficient degree of correlation between price trends for a Fund’s securities and futures contracts based on other financial instruments, securities indices or other indices, the Fund may also enter into such futures contracts as part of its hedging strategy. Although under some circumstances prices of securities the Fund owns may be more or less volatile than prices of such futures contracts, the Adviser will attempt to estimate the extent of this volatility difference based on historical patterns and compensate for any such differential by having the Fund enter into a greater or lesser number of futures contracts or by seeking to achieve only a partial hedge against price changes affecting the Fund’s securities. When hedging of this character is successful, any depreciation in the value of portfolio securities will be substantially offset by appreciation in the value of the futures position. On the other hand, any unanticipated appreciation in the value of the Fund’s securities would be substantially offset by a decline in the value of the futures position.

On other occasions, the Fund may take a “long” position by purchasing futures contracts. This would be done, for example, when the Fund anticipates the subsequent purchase of particular securities when it has the necessary cash, but expects the prices then available in the applicable market to be less favorable than prices that are currently available. Additionally, long positions in futures contracts may be used to hedge certain parts of the Fund which might be adversely affected by a drop in interest rates.

The acquisition of put and call options on futures contracts will give the Fund the right (but not the obligation) for a specified price to sell or to purchase, respectively, the underlying futures contract at any time during the option period. As the purchaser of an option on a futures contract, the Fund obtains the benefit of the futures position if prices move in a favorable direction but limits its risk of loss in the event of an unfavorable price movement to the loss of the premium and transaction costs.

The writing of a call option on a futures contract generates a premium, which may partially offset a decline in the value of the Fund’s assets. By writing a call option, the Fund becomes obligated, in exchange for the premium (upon exercise of the option), to sell a futures contract if the option is exercised, which may have a value higher than the exercise price. Conversely, the writing of a put option on a futures contract generates a premium, which may partially offset an increase in the price of securities that the Fund intends to purchase. However, the Fund becomes obligated (upon exercise of the option) to purchase a futures contract if the option is exercised, which may have a value lower than the exercise price. Thus, the loss incurred by the Fund in writing options on futures is potentially unlimited and may exceed the amount of the premium received. The Fund will incur transaction costs in connection with the writing of options on futures.

The holder or writer of an option on a futures contract may terminate its position by selling or purchasing an offsetting option on the same financial instrument. There is no

- 11 -

Table of Contents

guarantee that such closing transactions can be affected. The Fund’s ability to establish and close out positions on such options will be subject to the development and maintenance of a liquid market.

The Fund will engage in futures and related options transactions for bona fide hedging and to seek to increase total return as permitted by the CFTC regulations, which permit principals of an investment company, registered under the 1940 Act, to engage in such transactions without registering as commodity pool operators. The Fund will determine that the price fluctuations in the futures contracts and options on futures used for hedging purposes are substantially related to price fluctuations in securities held by the Fund or securities or instruments which it expects to purchase. Except as stated below, the Fund’s futures transactions will be entered into for traditional hedging purposes — i.e., futures contracts will be sold to protect against a decline in the price of securities that the Fund owns or securities purchased to protect the Fund against an increase in the price of securities it intends to purchase.

The Fund will engage in transactions in futures contracts and options only to the extent such transactions are consistent with the requirements of the Code, for maintaining its qualification as a regulated investment company for federal income tax purposes.

Transactions in futures contracts and options on futures involve brokerage costs require margin deposits and, in some cases, may require the Fund to establish a segregated account consisting of cash or liquid securities in an amount equal to the underlying value of such contracts and options.

Using futures contracts entails certain risks, including but not limited to the following: no assurance that futures contracts transactions can be offset at favorable prices; possible reduction of the Fund’s income due to the use of hedging; possible reduction in value of both the securities hedged and the hedging instrument; possible lack of liquidity due to daily limits on price fluctuations; imperfect correlation between the contract and the securities being hedged; and potential losses in excess of the amount initially invested in the futures contracts themselves. If the Adviser’s expectations regarding movements in securities prices or interest rates are incorrect, the Fund may have experienced better investment results without hedging. Using futures contracts and options on futures contracts requires special skills in addition to those needed to select portfolio securities.

While transactions in futures contracts and options on futures may reduce certain risks, such transactions themselves entail certain other risks. Thus, while the Fund may benefit from using futures and options on futures, unanticipated changes in interest rates or securities prices may result in a poorer overall performance for the Fund than if it had not entered into any futures contracts or options transactions. If there is an imperfect correlation between a futures position and a portfolio position which is intended to be protected, then the desired protection may not be obtained and the Fund may be exposed to risk of loss.

Perfect correlation between the Fund’s futures positions and portfolio positions will be impossible to achieve. There are no futures contracts based upon individual securities, except certain U.S. Government securities. Other futures contracts available to hedge the Fund’s portfolio investments generally are limited to futures on various financial indices.

Table of Contents

Transactions in futures contracts and options on futures involve brokerage costs, require margin deposits and, in some cases, may require the Fund to “set aside” (referred to sometimes as “asset segregation”) liquid assets, or engage in other measures approved by the SEC or its staff while the futures contracts and options are open. Typically, this means that the Fund will establish a segregated account consisting of cash or liquid securities in an amount equal to the aggregate underlying value of such contracts or options. In accordance with applicable federal securities laws, including the 1940 Act, related rules and various SEC and SEC staff positions, with respect to certain kinds of derivatives, the Fund must segregate assets. For example, with respect to forwards and futures contracts that are not contractually required to “cash settle,” the Fund must cover its open positions by setting aside liquid assets equal to the contracts’ full notional value. With respect to forwards, futures and index options that are contractually required to “cash settle,” however, the Fund is permitted to set aside liquid assets in an amount equal to the Fund’s daily marked-to-market (net) obligations, if any (i.e., the Fund’s daily net liability, if any), rather than the notional value. By setting aside assets equal to only its net obligations under cash settled forward, futures and index options contracts, the Fund will have the ability to employ leverage to a greater extent than if the Fund were required to segregate assets equal to the full notional value of such contracts. Using leverage involves certain risks. The Fund reserves the right to modify its asset segregation policies in the future to comply with any changes in the positions articulated from time to time by the SEC and its staff.

Interest Rate Swaps, Total Return Swaps, Credit Default Swaps, Options on Swaps and Interest Rate Caps, Floors and Collars

The Fund may enter into interest rate and total return swaps and interest rate caps, floors and collars. The Fund may also purchase and write (sell) options on swaps, commonly referred to as swaptions. The Fund may also enter into credit default swaps based on a specified underlying asset (or groups of assets or indices).

The Fund may enter into swap transactions for hedging purposes, to manage the Fund’s maturity, or to seek to increase total return. As examples, the Fund may enter into swap transactions 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 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 an economical way.

Swap agreements are two party contracts entered into primarily by institutional investors. 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 security, or in a “basket” of securities representing a particular index. As examples, interest rate

swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, such as an exchange of fixed-rate payments for floating rate payments. Total return swaps are contracts that obligate a party to pay or receive interest in exchange for payment by the other party of the total return generated by a security, a basket of securities, an index, or an index component. When the Fund is a buyer of a credit default swap (commonly known as buying protection), it may make periodic payments to the seller of the credit default swap to obtain protection against a credit default on a specified underlying asset (or group of assets or indices). If a default occurs, the seller of a credit default swap may be required to pay the Fund the “notional value” of the credit default swap on a specified security (or group of securities or indices). On the other hand, when the Fund is a seller of a credit default swap (commonly known as selling protection), in addition to the credit exposure the Fund has on the other assets held in its portfolio, the Fund is also subject to the credit exposure on the notional amount of the swap since, in the event of a credit default, the Fund may be required to pay the “notional value” of the credit default swap on a specified security (or groups of securities or indices) to the buyer of the credit default swap. The Fund will be the seller of a credit default swap only when the credit of the underlying asset is deemed by the Adviser to meet the Fund’s minimum credit criteria at the time the swap is first entered into.

A swaption is an option to enter into a swap agreement. Like other types of options, the buyer of a swaption pays a non-refundable premium for the option and obtains the right, but not the obligation, to enter into an underlying swap on agreed-upon terms. The seller of a swaption, in exchange for the premium, becomes obligated (if the option is exercised) to enter into an underlying swap on agreed-upon terms. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index exceeds a predetermined interest rate, to receive payment of interest on a notional principal amount from the party selling such interest rate cap. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling the interest rate floor. An interest rate collar is the combination of a cap and a floor that preserves a certain return within a predetermined range of interest rates.

A great deal of flexibility is possible in the way swap transactions are structured. Generally, however, the Fund will enter into interest rate and total return, swaps on a net basis, which means that the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. Interest rate and total return swaps do not normally involve the delivery of securities, other underlying assets or principal. Accordingly, the risk of loss with respect to interest rate and total return swaps is normally limited to the net amount of payments that the Fund is contractually obligated to make. If the other party to an interest rate or total return swap defaults, the Fund’s risk of loss consists of the net amount of payments that such Fund is contractually entitled to receive, if any.

To the extent that the Fund’s exposure in a transaction involving a swap, swaption or an interest rate floor, cap or collar is covered by the segregation of cash or liquid assets, or is covered by other means in accordance with SEC guidance, the Fund and the Adviser believe that the transactions do not constitute senior securities under the Act and, accordingly, will not treat them as being subject to the Fund’s borrowing restrictions.

Table of Contents

The Fund will not enter into any interest rate or total return swap transactions unless the unsecured commercial paper, senior debt or claims-paying ability of the other party is rated either A or A-1 or better by Standard & Poor’s or A or P-1 or better by Moody’s or their equivalent ratings, or, if unrated by such rating organization, determined to be of comparable quality by the Adviser.

The use of interest rate and total return swaps, as well as interest rate caps, floors and collars, is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. The use of a swap requires an understanding not only of the referenced asset, reference rate, or index but also of the swap itself, without the benefit of observing the performance of the swap under all possible market conditions. If the Adviser is incorrect in its forecasts of market values, credit quality, interest rates and currency exchange rates, the investment performance of the Fund would be less favorable than it would have been if these investment instruments were not used.

In addition, these transactions can involve greater risks than if the Fund had invested in the reference obligation directly because, in addition to general market risks, swaps are subject to illiquidity risk, counterparty risk, credit risk and pricing risk. Because they are two party contracts and because they may have terms of greater than seven days, swap transactions 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 if the swap counterparty defaults or files for bankruptcy protection. Many swaps are complex and often valued subjectively. Swaps may be subject to pricing or “basis” risk, which exists when a particular swap becomes extraordinarily expensive relative to historical prices or the price of corresponding cash market instruments. Under certain market conditions it may not be economically feasible to imitate a transaction or liquidate a position in time to avoid a loss or take advantage of an opportunity. If a swap transaction is particularly large or if the relevant market is illiquid, it may not be possible to initiate a transaction or liquidate a position at an advantageous time or price, which may result in significant losses.

The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid in comparison with the markets for other similar instruments which are traded in the interbank market. The Adviser, under the supervision of the Board of Directors, is responsible for determining and monitoring the liquidity of the Fund’s transactions in swaps, swaptions, caps, floors and collars.

Interest rate swaps and total return swaps on indices and sub-indices on instruments otherwise eligible for investment, and options thereon (including swaptions), futures (Treasury, Eurodollar and Federal Funds) and options (including put and call options on financial futures contracts); options on securities otherwise eligible for investment, interest rate caps, interest rate floors and interest rate collars may constitute derivative instruments. The Fund intends to use derivative instruments to adjust the Fund’s average maturity, particularly when the Fund receives new investments or redemption requests, manage or reduce the Fund’s exposure to risks, primarily interest rate risk, and/or to generate additional return (which may be considered speculative).

Zero Coupon Bonds. To the extent consistent with its investment objective, the Fund generally may invest in zero coupon bonds, which are debt securities that have been stripped of their unmatured interest coupons, the coupons themselves or receipts or certificates representing interests in such stripped debt obligations or coupons. A portion of the discount with respect to stripped tax-exempt securities or their coupons may be taxable.

Zero coupon bonds involve the additional risk that, unlike securities that periodically pay interest to maturity, the Fund will realize no cash until a specified future payment date unless a portion of such securities is sold and, if the issuer of such securities defaults, the Fund may obtain no return at all on its investment. In addition, even though such securities may not provide for the payment of current interest in cash, the Fund is nonetheless required to accrue income on such investments for each taxable year and generally is required to distribute such accrued amounts (net of deductible expenses, if any) to avoid being subject to tax. Because no cash is generally received at the time of the accrual, the Fund may be required to liquidate other portfolio securities to obtain sufficient cash to satisfy federal tax distribution requirements applicable to the Fund. Additionally, the market prices of zero coupon bonds generally are more volatile than the market prices of interest bearing securities and are likely to respond to a greater degree to changes in interest rates than interest bearing securities having similar maturities and credit quality.

Short Sales. The Fund may enter into short sales. Short sales are transactions in which the Fund sells a security it does not own in anticipation of a decline in the market value of that security. To complete such a transaction, the Fund must borrow the security to make delivery to the buyer. The Fund then is obligated to replace the security borrowed by purchasing it at the market price at the time of replacement. The price at such time may be more or less than the price at which the security was sold by the Fund. Until the security is replaced, the Fund is required to pay to the lender amounts equal to any dividend which accrues during the period of the loan. To borrow the security, the Fund also may be required to pay a premium, which would increase the cost of the security sold. The proceeds of the short sale will be retained by the broker, to the extent necessary to meet margin requirements, until the short position is closed out.

Until the Fund replaces a borrowed security in connection with a short sale, the Fund will: (a) maintain daily a segregated account, containing cash, cash equivalents, or liquid marketable securities, at such a level that (i) the amount deposited in the account plus the amount deposited with the broker as collateral will equal the current value of the security sold short and (ii) the amount deposited in the segregated account plus the amount deposited with the broker as collateral will not be less than the market value of the security at the time it was sold short; or (b) otherwise cover its short position in accordance with positions taken by the staff of the Securities and Exchange Commission (the “SEC”).

The Fund will incur a loss as a result of the short sale if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security. The Fund will realize a gain if the security declines in price between those dates. This result is the opposite of what one would expect from a cash purchase of a long position in a security. The amount of any gain will be decreased, and the amount of any loss increased, by the amount of any premium or amounts in lieu of interest the Fund may be required to pay in connection with a short sale. The Fund may purchase call options to provide a hedge against an increase in the price of a security sold short by the Fund.

The Fund anticipates that the frequency of short sales will vary substantially in different periods, and it does not intend that any specified portion of its assets, as a matter of practice, will be invested in short sales. However, no securities will be sold short if, after effect is given to any such short sale, the total market value of all securities sold short would exceed 100% of the value of the Fund’s net assets.

Leverage. Under the 1940 Act, the Fund may borrow an amount up to 33-1/3% of its total assets (including the amount borrowed) less all liabilities other than borrowings. Although the use of leverage by the Fund may create an opportunity for increased return, it also results in additional risks and can magnify the effect of any losses. If the income and gains earned on the securities and instruments purchased with leverage proceeds are greater than the cost of the leverage, the Fund’s return will be greater than if leverage had not been used. Conversely, if the income or gains from the securities and investments purchased with such proceeds does not cover the cost of leverage, the Fund’s return will be less than if leverage had not been used. There is no assurance that a leveraging strategy will be successful. Leverage involves risks and special considerations for the Fund including:

The Fund nevertheless may determine to continue to use leverage if the benefits to the Fund’s shareholders of maintaining the leveraged position are expected to outweigh the current reduced return.

Credit Quality. Short-term instruments purchased by the Fund will be rated in the highest rating category by at least two nationally recognized statistical rating organizations (“NRSROs”) (e.g., P-1 as rated by Moody’s Investors Service, Inc. (“Moody’s”) or A-1 as rated by Standard & Poor’s Rating Group (“S&P”)) or, in the case of short-term municipal securities, by at least one NRSRO (e.g., A-1 by S&P or MIG-1 or, in the case of variable rate demand obligations, VMIG-1, by Moody’s) . Corporate bonds will be rated in one of the three highest long-term rating categories by at least two NRSROs (e.g., A or higher by S&P or Moody’s). Asset-backed and mortgage-backed securities will be rated in one of the two highest long-term rating categories by at least one NRSRO (e.g., AA- or higher by S&P or Aa3 or higher by Moody’s). When a security requires a minimum rating by at least two NRSROs and only one NRSRO has rated the security, the security may be deemed to have met its rating requirement if it receives the minimum required rating from that NRSRO and it is determined by the Adviser to be of comparable credit quality. If no NRSRO has rated a security, the security may be deemed

to have met its rating requirement if it is determined by the Adviser to be of comparable credit quality. A security satisfies the Fund’s minimum rating requirement regardless of its relative rating (for example, plus or minus) within a designated major rating category. If a security satisfies the Fund’s minimum rating requirement at the time of purchase and is subsequently downgraded below that rating, the Fund will not be required to dispose of the security. If a downgrade occurs, the Adviser will consider which action, including the sale of the security, is in the best interest of the Fund and its shareholders. Debt securities purchased by the Fund may include securities issued by the U.S. Government (and its agencies, instrumentalities and sponsored enterprises), banks and other issuers. See Appendix A for a description of NRSRO ratings.

Portfolio Turnover. There are no limitations on the length of time that securities must be held by the Fund and the Fund’s annual portfolio turnover rate may vary significantly from year to year. A high rate of portfolio turnover (100% or more) involves correspondingly greater transaction costs, which would be borne by the Fund and its shareholders.

In determining such portfolio turnover, U.S. Government securities and all other securities (including options) which have maturities at the time of acquisition of one year or less (“short-term securities”) are excluded. The annual portfolio turnover rate is calculated by dividing the lesser of the cost of purchases or proceeds from sales of portfolio securities for the year by the monthly average of the value of the portfolio securities owned by the Fund during the year. The monthly average is calculated by totaling the values of the portfolio securities as of the beginning and end of the first month of the year and as of the end of the succeeding 11 months and dividing the sum by 13. A turnover rate of 100% would occur if all of the Fund’s securities (other than short-term securities) were replaced once in a period of one year. It should be noted that if the Fund were to write a substantial number of options, which are exercised, the portfolio turnover rate would increase.

INVESTMENT LIMITATIONS

The Fund has adopted the following fundamental investment limitations which may not be changed without the affirmative vote of the holders of a majority of the Fund’s outstanding shares (as defined in Section 2(a)(42) of the 1940 Act). As used in this SAI and in the Prospectus, “shareholder approval” and a “majority of the outstanding shares” of the Fund means, with respect to the approval of an investment advisory agreement or a change in a fundamental investment limitation, the lesser of (1) 67% of the shares of the Fund represented at a meeting at which the holders of more than 50% of the outstanding shares of such Fund are present in person or by proxy, or (2) more than 50% of the outstanding shares of such Fund. The Fund may not:

DISCLOSURE OF PORTFOLIO HOLDINGS

The Company has adopted, on behalf of the Fund, policies relating to the disclosure of the Fund’s securities. The policies relating to the disclosure of the Fund’s securities are designed to allow disclosure of portfolio holdings information where necessary to the Fund’s operation without compromising the integrity or performance of the Fund. It is the policy of the Company that disclosure of the Fund’s securities holdings to a select person or persons prior to the release of such holdings to the public (“selective disclosure”) is prohibited, unless there are legitimate business purposes for selective disclosure.

The Company discloses portfolio holdings information as required in regulatory filings and shareholder reports, discloses portfolio holdings information as required by federal and state securities laws and may disclose portfolio holdings information in response to requests by governmental authorities. As required by the federal securities laws, including the 1940 Act, the Company will disclose the Fund’s holdings in applicable regulatory filings, including shareholder reports, reports on Form N-CSR and Form N-Q or such other filings, reports or disclosure documents as the applicable regulatory authorities may require.

The Company may distribute or authorize the distribution of information about its portfolio holdings that is not publicly available to its third-party service providers of the Company, which include PFPC Trust Company, the custodian for the Fund; PFPC Inc. (“PFPC”), the administrator, accounting agent and transfer agent; Deloitte & Touche LLP, the Fund’s independent registered public accounting firm; Drinker Biddle & Reath LLP, legal counsel; GCom ² Solutions and RR Donnelley, the Fund’s financial printers; and Institutional Shareholder Services Inc. (“ISS”), the Fund’s proxy voting service. These service providers are required to keep such information confidential, and are prohibited from trading based on the information or otherwise using the information except as necessary in providing services to the Fund. Such holdings are released on conditions of confidentiality, which include appropriate trading prohibitions. “Conditions of confidentiality” include confidentiality terms included in written agreements, implied by the nature of the relationship (e.g. attorney-client relationship), or required by fiduciary or regulatory principles (e.g., custody services provided by financial institutions). Portfolio holdings may also be disclosed, upon authorization by a designated officer of the Adviser, to (i) certain independent reporting agencies recognized by the SEC as acceptable agencies for the reporting of industry statistical information, and (ii) financial consultants to assist them in determining the suitability of the Fund as an investment for their clients, in each case in accordance with the anti-fraud provisions of the federal securities laws and the Company’s and the Adviser’s fiduciary duties to Fund shareholders. Disclosures to financial consultants are also subject to a confidentiality agreement and/or trading restrictions as well as a 30-day time lag. The foregoing disclosures are made pursuant to the Company’s policy on selective disclosure of portfolio holdings. The Board of Directors of the Company or a committee thereof may, in limited circumstances, permit other selective disclosure of portfolio holdings subject to a confidentiality agreement and/or trading restrictions. Portfolio holdings may also be provided earlier to shareholders and their agents who receive redemptions in kind that reflect a pro rata allocation of all securities held in the Fund.

Any violations of the policy set forth above as well as any corrective action undertaken to address such violations must be reported by the Adviser, director, officer or third-party service provider to the Company’s Chief Compliance Officer, who will determine whether the violation should be reported immediately to the Board of Directors of the Company or at its next quarterly Board meeting.
