RISK FACTORS RELATING TO INVESTING IN HIGH-YIELD SECURITIES (“JUNK BONDS”)

Investments in securities rated below investment grade that are eligible for purchase by the Funds, and in particular the H IGH Y IELD B OND F UND , are described as speculative by both Moody’s and S&P. Lower-rated or unrated ( i.e., high-yield or “junk bond”) securities are more likely to react to developments affecting market risk (such as interest rate sensitivity, market perception of creditworthiness of the issuer and general market liquidity) and credit risk (such as the issuer’s inability to meet its obligations) than are more highly rated securities, which react primarily to movements in the general level of interest rates. The Adviser considers both credit risk and market risk in making investment decisions for the Funds. Investors should carefully consider the relative risk of investing in high-yield securities and understand that such securities are not generally meant for short-term trading. These high-yield securities are regarded as predominantly speculative with respect to the issuer’s continuing ability to meet principal and interest payments. Analysis of the creditworthiness of issuers of debt securities that are high-yield may be more complex than for issuers of higher quality debt securities.

High-yield securities may be more susceptible to real or perceived adverse economic and competitive industry conditions than investment grade securities. The prices of high yield securities have been found to be less sensitive to interest-rate changes than higher-rated investments, but more sensitive to adverse economic downturns or individual corporate developments. A projection of an economic downturn or of a period of rising interest rates, for example, could cause a decline in high yield security prices because the advent of a recession could lessen the ability of a highly leveraged company to make principal and interest payments on its debt securities. If an issuer of high-yield securities defaults, in addition to risking payment of all or a portion of interest and principal, the Funds investing in such securities may incur additional expenses to seek recovery. In the case of high-yield securities structured as zero-coupon or pay-in-kind securities, their market prices are affected to a greater extent by interest rate changes, and therefore tend to be more volatile than securities that pay interest periodically and in cash. The Adviser seeks to reduce these risks through diversification, credit analysis and attention to current developments and trends in both the economy and financial markets.

The amount of high-yield securities outstanding proliferated in the 1980’s in conjunction with the increase in merger and acquisition and leveraged buyout activity. Under adverse economic conditions, there is a risk that highly leveraged issuers may be unable to service their debt obligations upon maturity. In addition, the secondary market for high-yield securities, which is concentrated in relatively few market makers, may not be as liquid as the secondary market for more highly rated securities. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the values of high-yield securities, especially in a thinly traded market. Under adverse market or economic conditions, the secondary market for high-yield securities could contract further, independent of any specific adverse changes in the condition of a particular issuer. As a result, the Adviser could find it more difficult to sell these securities or may be able to sell the securities only at prices lower than if such securities were widely traded. Prices realized upon the sale of such lower-rated or unrated securities, under these circumstances, may be less than the prices used in calculating the Funds’ net asset value. Additionally, when secondary markets for high-yield securities are less liquid than the market for higher grade securities, it may be more difficult to value the securities because valuation may require more research, and elements of judgment may play a greater role in the valuation because there is less reliable, objective data available.

The use of credit ratings as the sole method of evaluating high-yield securities can involve certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high-yield securities. Also, credit rating agencies may fail to change credit ratings in a timely fashion to reflect events since the security was last rated. The Adviser does not rely solely on credit ratings when selecting securities for the Funds, and develops its own independent analysis of issuer credit quality. If a credit rating agency changes the rating of a portfolio security held by a Fund, the Fund may retain the portfolio security if the Adviser deems it in the best interest of shareholders.

Lower-rated or unrated debt obligations present risks based on payment expectations. If an issuer calls the obligation for redemption, a Fund may have to replace the security with a lower yielding security, resulting in a decreased return for investors. If a Fund experiences unexpected net redemptions, it may be forced to sell its higher- rated securities, resulting in a decline in the overall credit quality of the Fund’s portfolio and increasing the exposure of the Fund to the risks of high-yield securities.

PARTICIPATION ON CREDITOR COMMITTEES: Representatives of a Fund (in particular the H IGH Y IELD B OND F UND ) or the Adviser may from time to time participate on committees formed by creditors to negotiate with the management of financially troubled issuers of securities held by the Fund. Such participation may subject a Fund to expenses such as legal fees and may make a Fund an “insider” of the issuer for purposes of the federal securities laws, and therefore may restrict such Fund’s ability to trade in or acquire additional positions in a particular security when it might otherwise desire to do so. Participation by a Fund on such committees also may expose the Fund to potential liabilities under the federal bankruptcy laws or other laws governing the rights of creditors and debtors. A Fund will participate on such committees only when the Adviser believes that such participation is necessary or desirable to enforce the Fund’s rights as a creditor or to protect the value of securities held by the Fund.

REPURCHASE AGREEMENTS

Each Fund may enter into repurchase agreements involving U.S. Government securities or other collateral including mortgage-related products or corporate securities with commercial banks or broker-dealers, whereby the seller of a security agrees to repurchase the security from the Fund on an agreed-upon date in the future. While each Fund intends to be fully collateralized as to such agreements, and the collateral will be marked to market daily, if the person obligated to repurchase from the Fund defaults, there may be delays and expenses in liquidating the securities subject to the repurchase agreement, a decline in their value and a loss of interest income.

A repurchase transaction occurs when, at the time a Fund purchases a security, that Fund also resells it to a vendor (normally a commercial bank or broker-dealer) and must deliver the security (and/or securities substituted for them under the repurchase agreement) to the vendor on an agreed-upon date in the future. Such securities, including any securities so substituted, are referred to as the “Resold Securities.” The resale price is in excess of the purchase price in that it reflects an agreed-upon market interest rate effective for the period of time during which the Fund’s money is invested in the Resold Securities. The majority of these transactions run from day to day, and the delivery pursuant to the resale typically will occur within one to five days of the purchase. The Fund’s risk is limited to the ability of the vendor to pay the agreed-upon sum at the delivery date; in the event of bankruptcy or other default by the vendor, there may be possible delays and expenses in liquidating the instrument purchased, decline in its value and loss of interest. The Adviser will consider the creditworthiness of any vendor of repurchase agreements. Repurchase agreements can be considered as loans “collateralized” by the Resold Securities, and are defined as “loans” in the 1940 Act. The return on such collateral may be more or less than that from the repurchase agreement. The Resold Securities will be marked to market every business day so that the value of the collateral is at least equal to the value of the loan, including the accrued interest earned thereon. All Resold Securities will be held by the Fund’s custodian either directly or through a securities depository (tri-party repurchase agreement) or the Federal Reserve book-entry system.

REVERSE REPURCHASE AGREEMENTS

The Funds may enter into reverse repurchase agreements, whereby a Fund sells securities concurrently with entering into an agreement to repurchase those securities at a later date at a fixed price. During the reverse repurchase agreement period, the Fund continues to receive principal and interest payments on those securities. Reverse repurchase agreements are speculative techniques involving leverage and are considered borrowings by the Fund for purposes of the percentage limitations applicable to borrowings.

DOLLAR ROLLS

The Funds also may enter into dollar roll transactions in which the Funds sell a fixed income security for delivery in the current month and simultaneously contracts to purchase substantially similar (same type, coupon and maturity) securities at an agreed upon future time. By engaging in a dollar roll transaction, the Funds forego principal and interest paid on the security that is sold, but receive the difference between the current sales price and the forward price for the future purchase. The Funds would also be able to earn interest on the income that is received from the initial sale. The obligation to purchase securities on a specified future date involves the risk that the market value of the securities that the Funds are obligated to purchase may decline below the purchase price. In addition, in the event the other party to the transaction files for bankruptcy, becomes insolvent or defaults on its obligation, the Funds may be adversely affected.

SALE-BUYBACKS

The Funds also may effect simultaneous purchase and sale transactions that are known as “sale-buybacks.” A sale-buyback is similar to a reverse repurchase agreement, except that in a sale-buyback, the counterparty who purchases the security is entitled to receive any principal or interest payments made on the underlying security pending settlement of the Fund’s repurchase of the underlying security. A Fund’s obligations under a sale-buyback typically would be offset by liquid assets equal in value to the amount of the Fund’s forward commitment to repurchase the subject security.

U.S. GOVERNMENT SECURITIES

The Funds may invest in U.S. Government securities. U.S. Government securities include direct obligations issued by the United States Treasury, such as Treasury bills, certificates of indebtedness, notes, bonds and component parts of notes or bonds (including the principal of such obligations or the interest payments scheduled to be paid on such obligations). U.S. Government securities also can include securities issued or guaranteed by U.S. Government agencies and instrumentalities that issue or guarantee securities, including, but not limited to, the Federal National Mortgage Association (“FNMA”), Government National Mortgage Association (“GNMA”), Federal Home Loan Banks, Federal Financing Bank, Student Loan Marketing Association. Federal Home Loan Mortgage Corporation (“FHLMC”), Federal Intermediate Credit Banks, Federal Land Banks, Tennessee Valley Authority, Inter-

American Development Bank, Asian Development Bank and the International Bank for Reconstruction and Development. Certain of these entities are U.S. Government Sponsored Enterprises (“GSE”). Although the securities of these GSEs, and others like them, may be chartered or sponsored by Acts of Congress, their securities are neither issued nor guaranteed by the United States Treasury. For example, FNMA’s guarantee is supported by its ability to borrow from the U.S. Treasury, while FHLMC’s guarantee is backed by reserves set aside to protect holders against losses due to default.

Except for U.S. Treasury securities, obligations of U.S. Government agencies and instrumentalities may or may not be supported by the full faith and credit of the United States. Some are backed by the right of the issuer to borrow from the Treasury; others by discretionary authority of the U.S. Government to purchase the agencies’ obligations; while still others, such as the Student Loan Marketing Association, are supported only by the credit of the instrumentality. In the case of securities not backed by the full faith and credit of the United States, the investor must look principally to the agency or instrumentality issuing or guaranteeing the obligation for ultimate repayment, and may not be able to assert a claim against the United States itself in the event the agency or instrumentality does not meet its commitment. Each Fund will invest in securities of such instrumentality only when the Adviser is satisfied that the credit risk with respect to that instrumentality is acceptable.

Among the U.S. Government securities that may be purchased by the Funds are certain “mortgage-backed securities” of GNMA, the Federal Home Loan Mortgage Corporation (“FHLMC”) and FNMA. See the discussion under “Mortgage-Related Securities.”

The Funds may invest in component parts of the U.S. Treasury notes or bonds, namely, either the principal of such Treasury obligations or one of the interest payments scheduled to be paid on such obligations. These obligations may take the form of (i) Treasury obligations from which the interest coupons have been stripped, (ii) the interest coupons that are stripped, (iii) book-entries at a Federal Reserve member bank representing ownership of Treasury obligation components, or (iv) receipts evidencing the component parts (principal or interest) of Treasury obligations that have not actually been stripped. Such receipts evidence ownership of component parts of Treasury obligations (principal or interest) purchased by a third party (typically an investment banking firm) and held on behalf of the third party in physical or book-entry form by a major commercial bank or trust company pursuant to a custody agreement with the third party. These custodial receipts are known by various names, including “Treasury Receipts,” “Treasury Investment Growth Receipts” (TIGRs) and “Certificates of Accrual on Treasury Securities” (CATS), and are not issued by the U.S. Treasury, therefore they are not U.S. Government securities, although the underlying bonds represented by these receipts are debt obligations of the U.S. Treasury.

CORPORATE DEBT AND OTHER OBLIGATIONS

The Funds may invest in corporate debt securities, variable and floating rate debt securities and corporate commercial paper in the rating categories described above. Floating rate securities normally have a rate of interest which is set as a specific percentage of a designated base rate, such as the rate on Treasury bonds or bills or the prime rate at a major commercial bank. The interest rate on floating rate securities changes periodically when there is a change in the designated base rate. Variable rate securities provide for a specified periodic adjustment in the interest rate based on prevailing market rates.

The Funds may invest in corporate debt securities with contractual call provisions that permit the seller of the security to repurchase the security at a pre-determined price. The market price typically reflects the presence of a call provision.

The Funds may invest in structured debentures and structured notes. These are hybrid instruments with characteristics of both bonds and swap agreements. Like a bond, these securities make regular coupon payments and generally have fixed principal amounts. However, the coupon payments are typically tied to a swap agreement which can be affected by changes in a variety of factors such as exchange rates, the shape of the yield curve and foreign interest rates. Because of these factors, structured debentures and structured notes can display price behavior that is more volatile than and often not correlated to other fixed-income securities.

The Funds may also invest in inverse floaters and tiered index bonds. An inverse floater is a type of derivative that bears a floating or variable interest rate that moves in the opposite direction to the interest rate on another security or index level. Changes in the interest rate of the other security or index inversely affect the residual interest rate paid on the inverse floater, with the result that the inverse floater’s price will be considerably more volatile than that of a fixed-rate bond. Tiered index bonds are also a type of derivative instrument. The interest rate on a tiered index bond is tied to a specified index or market rate. So long as this index or market rate is below a predetermined “strike” rate, the interest rate on the tiered index bond remains fixed. If, however, the specified index or market rate rises above the “strike” rate, the interest rate on the tiered index bond will decrease. In general, the interest rates on tiered index bonds and inverse floaters move in the opposite direction of prevailing interest rates. The market for inverse floaters and tiered index bonds is relatively new. These corporate debt obligations may have characteristics similar to those of mortgage-related securities, but corporate debt obligations, unlike mortgage-related securities, are not subject to prepayment risk other than through contractual call provisions which generally impose a penalty for prepayment.

A Fund’s investments in U.S. dollar or foreign currency-denominated corporate debt securities of domestic or foreign issuers are limited to corporate debt securities (corporate bonds, debentures, notes or other similar corporate debt instruments) which meet the minimum ratings criteria set forth for the Fund, or, if unrated, which are in the Adviser’s opinion comparable in quality to corporate debt securities in which the Fund may invest. These criteria are described in the Prospectus. The rate of return or return of principal on some debt obligations may be linked or indexed to the level of exchange rates between the U.S. dollar and a foreign currency or currencies.

DELAYED FUNDING LOANS AND REVOLVING CREDIT FACILITIES

The Funds may enter into, or acquire participations in, delayed funding loans and revolving credit facilities, in which a lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. These commitments may have the effect of requiring a Fund to increase its investment in a company at a time when it might not otherwise decide to do so (including at a time when the company’s financial condition makes it unlikely that such amounts will be repaid). To the extent that a Fund is committed to advance additional funds, it will segregate assets determined to be liquid by the Adviser in accordance with procedures established by the Board of Trustees in an amount sufficient to meet such commitments. Delayed funding loans and revolving credit facilities are subject to credit, interest rate and liquidity risk of being a lender.

CONVERTIBLE SECURITIES

The Funds may invest in convertible securities of domestic or foreign issuers that meet the ratings criteria set forth in the Prospectus. A convertible security is a fixed-income security (a bond or preferred stock) which may be converted at a stated price within a specific period of time into a certain quantity of common stock or other equity securities of the same or a different issuer. Convertible securities rank senior to common stock in a corporation’s capital structure but are usually subordinated to similar non-convertible securities. While providing a fixed-income stream (generally higher in yield than the income derivable from common stock but lower than that afforded by a similar non-convertible security), a convertible security also offers an investor the opportunity, through its conversion feature, to participate in the capital attendant upon a market price advance in the convertible security’s underlying common stock.

In general, the market value of a convertible security is at least the higher of its “investment value” ( i.e. , its value as a fixed-income security) or its “conversion value” ( i.e. , its value upon conversion into its underlying stock). As a fixed-income security, a convertible security tends to increase in market value when interest rates decline and tends to decrease in value when interest rates rise. However, the price of a convertible security is also influenced by the market value of the security’s underlying stock. The price of a convertible security tends to increase as the market value of the underlying stock rises, whereas it tends to decrease as the market value of the underlying stock declines. While no securities investment is without some risk, investments in convertible securities generally entail less risk than investments in the stock of the same issuer.

With respect to the S TRATEGIC I NCOME F UND , because the investment characteristics of each convertible security vary, that variety enables the Fund to use convertible securities in different ways to pursue its investment objective of maximizing long-term total return without tracking any particular markets or indices. For example, the Fund can invest in: convertible securities that provide a relatively high level of income, with less appreciation potential; convertible securities that have high appreciation potential and a relatively low level of income; or convertible securities that provide some combination of both income and appreciation potential.

WARRANTS TO PURCHASE SECURITIES

The H IGH Y IELD B OND F UND and S TRATEGIC I NCOME F UND may invest in or acquire warrants to purchase equity or fixed income securities. Bonds with warrants attached to purchase equity securities have many characteristics of convertible bonds and their prices may, to some degree, reflect the performance of the underlying stock. Bonds also may be issued with warrants attached to purchase additional fixed income securities at the same coupon rate. A decline in interest rates would permit the Funds to buy additional bonds at the favorable rate or to sell the warrants at a profit. If interest rates rise, the warrants would generally expire with no value.

LOANS OF PORTFOLIO SECURITIES

U LTRA S HORT B OND F UND , the I NTERMEDIATE B OND F UND , the T OTAL R ETURN B OND F UND , the H IGH Y IELD B OND F UND , the S TRATEGIC I NCOME F UND and the A LPHA T RAK 500 F UND are authorized to lend their portfolio securities in an effort to increase the return and income on the Fund’s portfolio. A Fund that loans portfolio securities will typically loan those securities to well-known and recognized U.S. and foreign brokers, dealers and banks. These loans, if and when made, may not exceed one-third of the value of the Fund’s total assets. The Funds’ loans of securities will be collateralized by cash, letters of credit, government securities or qualifying liquid securities. The Funds will retain the right to all interest and dividends payable with respect to the loaned securities. If a Fund lends its portfolio securities it may charge the borrower a negotiated fee and retain the ability to terminate the loan at any time. In lending securities, a Fund will be subject to risks, including the potential inability to recall the loaned securities should the borrower fail financially, and the possible loss in market value of the collateral. While voting rights on the loaned securities may pass to the borrower, the Trust’s Board of Trustees must be able to terminate the loan and regain the right to vote the securities if a material event adversely affecting the investment occurs.

WHEN-ISSUED SECURITIES

The Funds may purchase securities on a when-issued or delayed-delivery basis, generally in connection with an underwriting or other offering. When-issued and delayed-delivery transactions occur when securities are bought with payment for and delivery of the securities scheduled to take place at a future time, beyond normal settlement dates, generally from 15 to 45 days after the transaction. The price that the Fund is obligated to pay on the settlement date may be different from the market value on that date. While securities may be sold prior to the settlement date, the Funds intend to purchase such securities with the purpose of actually acquiring them, unless a sale would be desirable for investment reasons. At the time the Fund makes a commitment to purchase a security on a when-issued basis, it will record the transaction and reflect the value of the security each day in determining the Fund’s net asset value. The Fund will also designate liquid securities, marked-to-market daily, equal in value to its obligations for when-issued securities.

SHORT SALES

If a Fund anticipates that the price of a security will decline, it may sell the security “short” and borrow the same security from a broker or other institution to complete the sale. The Fund may make a profit or loss depending upon whether the market price of the security decreases or increases between the date of the short sale and the date on which the Fund must replace the borrowed security. Until the security is replaced, the Fund generally is required to pay to the lender amounts equal to any interest which accrues during the period of the loan. To borrow the security, the Fund also may be required to pay a premium, which would also increase the cost of the security sold. The proceeds of the short sale will be retained by the broker (or by the Fund’s custodian in a special custody account), to the extent necessary to meet the margin requirements, until the short position is closed out.

Until the Fund closes its short position or replaces the borrowed security, the Fund will designate liquid 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 designated 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.

The H IGH Y IELD B OND F UND and S TRATEGIC I NCOME F UND may not make short sales of securities or maintain a short position if the value of the short position would exceed 33  ¹ / 3 % of the Fund’s total assets (taken at current value). Each of the other Funds may not make short sales of securities or maintain a short position if more than 25% of the Fund’s net assets (taken at current value) are held as collateral for such sales at any one time.

MORTGAGE-RELATED SECURITIES

The Funds may invest in residential or commercial mortgage-related securities, including mortgage pass-through securities, collateralized mortgage obligations (“CMOs”), adjustable rate mortgage securities, CMO residuals, stripped mortgage-related securities, floating and inverse floating rate securities and tiered index bonds. CMOs and other mortgage-related securities that are issued or guaranteed by the U.S. Government or by any of its agencies or instrumentalities will be considered U.S. Government securities for purposes of applying a Fund’s diversification tests. Generally, the entity that has the ultimate responsibility for the payment of interest and principal on a security is deemed to be the issuer of an obligation.

MORTGAGE PASS-THROUGH SECURITIES: Mortgage pass-through securities represent interests in pools of mortgages in which payments of both principal and interest on the securities are generally made monthly, in effect “passing through” monthly payments made by borrowers on the residential or commercial mortgage loans which underlie the securities (net of any fees paid to the issuer or guarantor of the securities). Mortgage pass-through securities differ from other forms of debt securities, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. Early payment of principal on mortgage pass-through securities (arising from prepayments of principal due to the sale of underlying property, refinancing, or foreclosure, net of fees and costs which may be incurred) may expose a Fund to a lower rate of return upon reinvestment of principal. Also, if a security subject to repayment has been purchased at a premium, in the event of prepayment, the value of the premium would be lost.

There are currently three types of mortgage pass-through securities, (i) those issued by the U.S. Government or one of its agencies or instrumentalities, such as the Government National Mortgage Association (“GNMA”), the Federal National Mortgage Association (“FNMA”) and the Federal Home Loan Mortgage Corporation (“FHLMC”); (ii) those issued by private issuers that represent an interest in or are collateralized by pass-through securities issued or guaranteed by the U.S. Government or one of its agencies or instrumentalities; and (iii) those issued by private issuers that represent an interest in or are collateralized by whole mortgage loans or pass-through securities without a government guarantee but usually having some form of private credit enhancement.

Page 12

Table of Contents

GNMA is a wholly-owned United States Government corporation within the Department of Housing and Urban Development. GNMA is authorized to guarantee, with the full faith and credit of the United States Government, the timely payment of principal and interest on securities issued by the institutions approved by GNMA (such as savings and loan institutions, commercial banks and mortgage banks), and backed by pools of FHA-insured or VA-guaranteed mortgages.

Obligations of FNMA and FHLMC are not backed by the full faith and credit of the United States Government. In the case of obligations not backed by the full faith and credit of the United States Government, a Fund must look principally to the agency issuing or guaranteeing the obligation for ultimate repayment. FNMA and FHLMC may borrow from the U.S. Treasury to meet their obligations, but the U.S. Treasury is under no obligation to lend to FNMA or FHLMC.

Private mortgage pass-through securities are structured similarly to GNMA, FNMA and FHLMC mortgage pass-through securities and are issued by originators of and investors in mortgage loans, including depository institutions, mortgage banks, investment banks and special purpose subsidiaries of the foregoing. Pools created by private mortgage pass-through issuers generally offer a higher rate of interest than government and government-related pools because there are no direct or indirect government or agency guarantees of payments in the private pools. However, timely payment of interest and principal of these pools may be supported by various forms of insurance or guarantees, including individual loan, title, pool and hazard insurance and letters of credit. The insurance and guarantees are issued by governmental entities, private insurers and the mortgage poolers. The insurance and guarantees and the credit worthiness of the issuers thereof will be considered in determining whether a mortgage-related security meets the Funds’ investment quality standards. There can be no assurance that the private insurers or guarantors can meet their obligations under the insurance policies or guarantee arrangements. Private mortgage pass-through securities may be bought without insurance or guarantees if, through an examination of the loan experience and practices of the originator/services and poolers, the Adviser determines that the securities meet the Funds’ quality standards.

COLLATERALIZED MORTGAGE OBLIGATIONS: CMOs, including CMOs that have elected to be treated for federal income tax purposes as Real Estate Mortgage Investment Conduits (“REMICs”), are hybrid instruments with characteristics of both bonds and mortgage pass-through securities. CMOs are debt obligations collateralized by residential or commercial mortgage loans or residential or commercial mortgage pass-through securities. Interest and prepaid principal are generally paid monthly. CMOs may be collateralized by whole mortgage loans or private mortgage pass-through securities but are more typically collateralized by portfolios of mortgage pass-through securities guaranteed by GNMA, FHLMC or FNMA. The issuer of a series of CMOs may elect to be treated for tax purposes as a REMIC. All future references to CMOs shall also be deemed to include REMICs.

CMOs are structured into multiple classes, each bearing a different stated maturity. Monthly payment of principal received from the pool of underlying mortgages, including prepayments, is first returned to investors holding the shortest maturity class. Investors holding the longer maturity classes usually receive principal only after shorter classes have been retired. An investor may be partially protected against a sooner than desired return of principal because of the sequential payments.

Certain issuers of CMOs are not considered investment companies pursuant to a rule recently adopted by the Securities and Exchange Commission (“SEC”), and the Funds may invest in the securities of such issuers without the limitations imposed by the 1940 Act on investments by the Fund in other investment companies. In addition, in reliance on an earlier SEC interpretation, the Fund’s investments in certain other qualifying CMOs, which cannot or do not rely on the rule, are also not subject to the limitation of the 1940 Act on acquiring interests in other investment companies. In order to be able to rely on the SEC’s interpretation, issuers of these CMOs must be unmanaged, fixed asset issuers, that (a) invest primarily in mortgage-backed securities, (b) do not issue redeemable securities, (c) operate under general exemptive orders exempting them from all provisions of the 1940 Act and (d) are not registered or regulated under the 1940 Act as investment companies. To the extent that the Funds select CMOs that cannot rely on the rule or do not meet the above requirements, the Funds may not invest more than 10% of their assets in all such entities and may not acquire more than 3% of the voting securities of any single entity.

The Funds also may invest in, among other things, parallel pay CMOs, Planned Amortization Class CMOs (“PAC bonds”), sequential pay CMOs, and floating rate CMOs. Parallel pay CMOs are structured to provide payments of principal on each payment date to more than one class. PAC bonds generally require payments of a specified amount of principal on each payment date. Sequential pay CMOs generally pay principal to only one class while paying interest to several classes. Floating rate CMOs are securities whose coupon rate fluctuates according to some formula related to an existing mortgage index or rate. Typical indices would include the Eleventh District Cost-of-Funds Index, the London Interbank Offered Rate, one-year Treasury yields, and ten-year Treasury yields.

ADJUSTABLE RATE MORTGAGE SECURITIES: Adjustable rate mortgage securities (“ARMs”) are pass-through securities collateralized by mortgages with adjustable rather than fixed rates. ARMs eligible for inclusion in a mortgage pool generally provide for a fixed initial mortgage interest rate for either the first three, six, twelve, thirteen, 36, or 60 scheduled monthly payments. Thereafter, the interest rates are subject to periodic adjustment based on changes to a designated benchmark index.

Page 13

Table of Contents

The ARMs contain maximum and minimum rates beyond which the mortgage interest rate may not vary over the lifetime of the security. In addition, certain ARMs provide for additional limitations on the maximum amount by which the mortgage interest may be adjusted for any single adjustment period. In the event that market rates of interest rise more rapidly to levels above that of the ARM’s maximum rate, the ARM’s coupon may represent a below market rate of interest. In these circumstances, the market value of the ARM security will likely have fallen.

Some ARMs contain limitations on changes in the required monthly payment. In the event that a monthly payment is not sufficient to pay the interest accruing on an ARM, any such excess interest is added to the principal balance of the mortgage loan, which is repaid through future monthly payments. If the monthly payment for such an instrument exceeds the sum of the interest accrued at the applicable mortgage interest rate and the principal payment required at such point to amortize the outstanding principal balance over the remaining term of the loan, the excess is then utilized to reduce the outstanding principal balance of the ARM.

CMO RESIDUALS: CMO residuals are derivative mortgage securities issued by agencies or instrumentalities of the U.S. Government or by private originators of, or investors in, mortgage loans, including savings and loan associations, homebuilders, mortgage banks, commercial banks, investment banks, and special purpose entities of the foregoing.

The cash flow generated by the mortgage assets underlying a series of CMOs is applied first to make required payments of principal and interest on the CMOs and second to pay the related administrative expenses of the issuer. The residual in a CMO structure generally represents the interest in any excess cash flow remaining after making the foregoing payments. Each payment of such excess cash flow to a holder of the related CMO residual represents income and/or a return of capital. The amount of residual cash flow resulting from a CMO will depend on, among other things, the characteristics of the mortgage assets, the coupon rate of each class of CMO, prevailing interest rates, the amount of administrative expenses and the prepayment experience on the mortgage assets. In part, the yield to maturity on the CMO residuals is extremely sensitive to prepayments on the related underlying mortgage assets, in the same manner as an interest-only (“IO”) class of stripped mortgage-related securities. See “Stripped Mortgage- Related Securities” below. In addition, if a series of a CMO includes a class that bears interest at an adjustable rate, the yield to maturity on the related CMO residual will also be extremely sensitive to changes in the level of the index upon which interest rate adjustments are based. As described below with respect to stripped mortgage-related securities, in certain circumstances a Fund may fail to recoup its initial investment in a CMO residual.

CMO residuals are generally purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers. The CMO residual market has recently developed and CMO residuals currently may not have the liquidity of other more established securities trading in other markets. Transactions in CMO residuals are generally completed only after careful review of the characteristics of the securities in question. In addition, CMO residuals may or, pursuant to an exemption, may not have been registered under the Securities Act. CMO residuals, whether or not registered under the Securities Act, may be subject to certain restrictions on transferability, and may be deemed “illiquid” and subject to a Fund’s limitations on investment in illiquid securities.

STRIPPED MORTGAGE-RELATED SECURITIES: Stripped mortgage-related securities (“SMRS”) are derivative multi- class mortgage securities. SMRS may be issued by agencies or instrumentalities of the U.S. Government, or by private originators of, or investors in, mortgage loans, including savings and loan associations, mortgage banks, commercial banks, investment banks, and special purpose entities of the foregoing.

SMRS are usually structured with two classes that receive different proportions of the interest and principal distributions on a pool of mortgage assets. A common type of SMRS will have one class receiving some of the interest and most of the principal from the mortgage assets, while the other class will receive most of the interest and the remainder of the principal. In the most extreme case, one class will receive all of the interest, (the “IO” class), while the other class will receive the entire principal (the principal-only or “PO” class). The yield to maturity on an IO class is extremely sensitive to the rate of principal payments (including prepayments) on the related underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on a Fund’s yield to maturity from these securities. If the underlying mortgage assets experience greater than anticipated prepayments of principal, a Fund may fail to fully recoup its initial investment in these securities even if the security is in one of the highest rating categories.

SMRS are purchased and sold by institutional investors through several investment banking firms acting as brokers or dealers. Although the market for these securities is increasingly liquid, the Adviser may determine that certain stripped mortgage-backed securities issued by the U. S. government, its agencies or instrumentalities are not readily marketable. If so, these securities, together with privately- issued stripped mortgage- backed securities, will be considered illiquid and subject to a Fund’s limitations on investment in illiquid securities. Whether a particular U. S. government-issued IO or PO backed by fixed-rate mortgages is liquid is assessed on a case by case basis under guidelines and standards established by the Funds’ Board of Trustees. The Funds also may invest in stripped mortgage-backed securities that are privately issued. These securities will be considered illiquid for purposes of each Fund’s limit on illiquid securities.

INVERSE FLOATERS: An inverse floater is a debt instrument with a floating or variable interest rate that moves in the opposite direction to the interest rate on another security or index level. Changes in the interest rate on the other security or index inversely affect the residual interest rate paid on the inverse floater, with the result that the inverse floater’s price will be considerably more volatile than that of a fixed-rate bond. Inverse floaters may experience gains when interest rates fall and may suffer losses in periods of rising interest rates. The market for inverse floaters is relatively new.

TIERED INDEX BONDS: Tiered index bonds are relatively new forms of mortgage-related securities. The interest rate on a tiered index bond is tied to a specified index or market rate. So long as this index or market rate is below a predetermined “strike” rate, the interest rate on the tiered index bond remains fixed. If, however, the specified index or market rate rises above the “strike” rate, the interest rate of the tiered index bond will decrease. Thus, under these circumstances, the interest rate on a tiered index bond, like an inverse floater, will move in the opposite direction of prevailing interest rates, with the result that the price of the tiered index bond may be considerably more volatile than that of a fixed-rate bond.

ASSET-BACKED SECURITIES

The Funds may invest in securities issued by trusts and special purpose corporations with principal and interest payouts backed by, or supported by, any of various types of assets. These assets typically include receivables related to the purchase of automobiles, credit card loans, and home equity loans. These securities generally take the form of a structured type of security, including pass-through, pay-through, and stripped interest payout structures similar to the CMO structure. Investments in these and other types of asset-backed securities must be consistent with the investment objectives and policies of the Funds.

RISK FACTORS RELATING TO INVESTING IN MORTGAGE-RELATED AND ASSET-BACKED SECURITIES

The yield characteristics of mortgage-related and asset-backed securities differ from traditional debt securities. Among the major differences are that interest and principal payments are made more frequently, usually monthly, and that principal may be prepaid at any time because the underlying mortgage loans or other assets generally may be prepaid at any time. As a result, if the Funds purchase such a security at a premium, a prepayment rate that is faster than expected will reduce yield to maturity, while a prepayment rate that is slower than expected will have the opposite effect of increasing yield to maturity. Alternatively, if the Funds purchase these securities at a discount, faster than expected prepayments will increase, while slower than expected prepayments will reduce, yield to maturity. The Funds may invest a portion of their assets in derivative mortgage-related securities which are highly sensitive to changes in prepayment and interest rates. The Adviser will seek to manage these risks (and potential benefits) by diversifying its investments in such securities and through hedging techniques.

During periods of declining interest rates, prepayment of mortgages underlying mortgage-related securities can be expected to accelerate. Accordingly, a Fund’s ability to maintain positions in high-yielding mortgage-related securities will be affected by reductions in the principal amount of such securities resulting from such prepayments, and its ability to reinvest the returns of principal at comparable rates is subject to generally prevailing interest rates at that time. Prepayments may also result in the realization of capital losses with respect to higher yielding securities that had been bought at a premium or the loss of opportunity to realize capital gains in the future from possible future appreciation.

Asset-backed securities involve certain risks that are not posed by mortgage-related securities, resulting mainly from the fact that asset-backed securities do not usually contain the complete benefit of a security interest in the related collateral. For example, credit card receivables generally are unsecured and the debtors are entitled to the protection of a number of state and Federal consumer credit laws, some of which may reduce the ability to obtain full payment. In the case of automobile receivables, due to various legal and economic factors, proceeds from repossessed collateral may not always be sufficient to support payments on these securities.

COLLATERALIZED BOND OBLIGATIONS (“CBOs”), COLLATERALIZED LOAN OBLIGATIONS (“CLOs”) AND OTHER COLLATERALIZED DEBT OBLIGATIONS (“CDOs”)

The Funds may invest in CBOs, CLOs and other CDOs, which are debt instruments backed solely by a pool of other debt securities. The risks of an investment in a CBO, CLO or other CDO depend largely on the type of the collateral securities (which would have the risks described elsewhere in this document for that type of security) and the class of the CBO, CLO or other CDO in which a Fund invests. Some CBOs, CLOs and other CDOs have credit ratings, but are typically issued in various classes with various priorities. Normally, CBOs, CLOs and other CDOs are privately offered and sold (that is, not registered under the securities laws) and may be characterized by the Funds as illiquid securities, but an active dealer market may exist for CBOs, CLOs and other CDOs that qualify for Rule 144A transactions. In addition to the normal interest rate, default and other risks of fixed income securities discussed elsewhere in this document, CBOs, CLOs and other CDOs carry additional risks, including the possibility that distributions from collateral securities will not be adequate to make interest or other payments, the quality of the collateral may decline in value or default, the Funds may invest in CBOs, CLOs or other CDOs that are subordinate to other classes, volatility in values, and the complex structure of the security may not be fully understood at the time of investment and produce disputes with the issuer or unexpected investment results.

BANK OBLIGATIONS

Bank obligations in which the Funds may invest include certificates of deposit, bankers’ acceptances and time deposits. Certificates of deposit are negotiable certificates issued against funds deposited in a commercial bank for a definite period of time and earning a specific return. Bankers’ acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are “accepted” by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties which vary depending upon market conditions and the remaining maturity of the obligation. There are no contractual restrictions on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits.

Obligations of foreign banks involve somewhat different risks than those affecting obligations of United States banks, including the possibility that their liquidity could be impaired because of future political and economic developments, that their obligations may be less marketable than comparable obligations of United States banks, that a foreign jurisdiction might impose withholding taxes on interest income payable on those obligations, that foreign deposits may be seized or nationalized, that foreign governmental restrictions such as exchange controls may be adopted which might adversely affect the payment of principal or interest on those obligations and that the selection of those obligations may be more difficult because there may be less publicly available information concerning foreign banks or the accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ from those applicable to United States banks. Foreign banks are not generally subject to examination by any U.S. Government agency or instrumentality.

LOAN PARTICIPATIONS

The Funds may purchase participations in commercial loans, or may purchase assignments of such loans. Such indebtedness may be secured or unsecured. Loan participations typically represent direct participation in a loan to a corporate borrower, and generally are offered by banks or other financial institutions or lending syndicates. The Funds may participate in such syndications, or can buy part of a loan, becoming a part lender. When purchasing loan participations, a Fund assumes the credit risk associated with the corporate borrower and may assume the credit risk associated with an interposed bank or other financial intermediary. The participation interests in which a Fund intends to invest may not be rated by any nationally recognized rating service. Participations and assignments also involve special types of risk, including interest rate risk, liquidity risk, and the risks of being a lender. If the Fund purchases a participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of the lender in addition to the borrower.

A loan is often administered by an agent bank acting as agent for all holders. The agent bank administers the terms of the loan, as specified in the loan agreement. In addition, the agent bank is normally responsible for the collection of principal and interest payments from the corporate borrower and the apportionment of these payments to the credit of all institutions that are parties to the loan agreement. Unless, under the terms of the loan or other indebtedness, a Fund has direct recourse against the corporate borrower, the Fund may have to rely on the agent bank or other financial intermediary to apply appropriate credit remedies against a corporate borrower.

A financial institution’s employment as agent bank might be terminated in the event that it fails to observe a requisite standard of care or becomes insolvent. A successor agent bank would generally be appointed to replace the terminated agent bank, and assets held by the agent bank under the loan agreement should remain available to holders of such indebtedness. However, if assets held by the agent bank for the benefit of a Fund were determined to be subject to the claims of the agent bank’s general creditors, the Fund might incur certain costs and delays in realizing payment on a loan or loan participation and could suffer a loss of principal and/or interest. In situations involving other interposed financial institutions ( e.g. , an insurance company or governmental agency) similar risks may arise.

Purchasers of loans and other forms of direct indebtedness depend primarily upon the creditworthiness of the corporate borrower for payment of principal and interest. If a Fund does not receive scheduled interest or principal payments on such indebtedness, the Fund’s share price and yield could be adversely affected. Loans that are fully secured offer a Fund more protection than an unsecured loan in the event of non-payment of scheduled interest or principal. However, there is no assurance that the liquidation of collateral from a secured loan would satisfy the corporate borrower’s obligation, or that the collateral can be liquidated.

The Funds may invest in loan participations with credit quality comparable to that of issuers of its securities investments. Indebtedness of companies whose creditworthiness is poor involves substantially greater risks, and may be highly speculative. Some companies may never pay off their indebtedness, or may pay only a small fraction of the amount owned. Consequently, when investing in indebtedness of companies with poor credit, a Fund bears a substantial risk of losing the entire amount invested.

Page 16

Table of Contents

Loan assignments, loan participations, delayed funding loans, revolving credit facilities, bridge loans and other types of direct indebtedness may not be readily marketable and may be subject to restrictions on resale. In some cases, negotiations involved in disposing of indebtedness may require weeks to complete. Consequently, some indebtedness may be difficult or impossible to dispose of readily at what the Adviser believes to be a fair price. Certain types of loans, such as bridge loans (especially those in which the H IGH Y IELD B OND F UND may invest) may provide certain types of equity features such as warrants and conversion rights. Those equity-type instruments and investments involve additional risks of an investment in equity, including potentially significant changes in value, difficulty in accurately valuing them, a lack of liquidity, and a significant loss on the investment, and the possibility that the particular right could expire worthless if not exercised.

In addition, valuation of illiquid indebtedness involves a greater degree of judgment in determining a Fund’s net asset value than if that value were based on available market quotations, and could result in significant variations in the Fund’s daily share price. At the same time, some loan interests are traded among certain financial institutions and accordingly may be deemed liquid. As the market for different types of indebtedness develops, the liquidity of these instruments is expected to improve. In addition, the Funds currently intend to treat indebtedness for which there is no readily available market as illiquid for purposes of the Funds’ limitation on illiquid investments. There may not be a recognizable, liquid public market for loan participations. To the extent this is the case, a Fund would consider the loan participation as illiquid and subject to the Fund’s restriction on investing no more than 15% of its net assets in illiquid securities. (See also the discussion entitled “Illiquid Securities.”)

Each Fund limits the amount of it total assets that it will invest in any one issuer or in issuers within the same industry (see “Investment Restrictions”). For purposes of these limits, a Fund will generally treat the corporate borrower as the “issuer” of indebtedness held by the Fund. In the case of loan participations where a bank or other lending institution serves as a financial intermediary between the Fund and the corporate borrower, Securities and Exchange Commission (“SEC”) interpretations require the Fund to treat both the lending bank or other lending institution and the corporate borrower as “issuers” for the purpose of determining whether the Fund has invested more than 5% of its total assets in a single issuer. Treating a financial intermediary as an issuer of indebtedness may restrict the Funds’ ability to invest in indebtedness related to a single financial intermediary, or a group of intermediaries engaged in the same industry, even if the underlying borrowers represent many different companies and industries.

Loans and other types of direct indebtedness may not be readily marketable and may be subject to restrictions on resale. In some cases, negotiations involved in disposing of indebtedness may require weeks to complete. Consequently, some indebtedness may be difficult or impossible to dispose of readily at what the Adviser believes to be a fair price. In addition, valuation of illiquid indebtedness involves a greater degree of judgment in determining a Fund’s net asset value than if the value were based on available market quotations, and could result in significant variations in the Fund’s daily share price. At the same time, some loan interests are traded among certain financial institutions and accordingly may be deemed liquid. As the market for different types of indebtedness develops, the liquidity of these instruments is expected to improve. In addition, the Funds’ currently intend to treat indebtedness for which there is no readily available market as illiquid for purposes of the Fund’s limitation on illiquid investments. The liquidity of each loan investment will be reviewed according to the requirements of the Funds’ Board approved liquidity policy. Investments in loan participations are considered to be debt obligations for purposes of any investment restriction relating to the lending of funds or assets by a Fund.

Investments in loans through a direct assignment of the financial institution’s interests with respect to the loan may involve additional risks to the Funds. For example, if the loan is foreclosed, a Fund could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, it is conceivable that under emerging legal theories of lender liability, a Fund could be held liable as co-lender. It is unclear whether loans and other forms of direct indebtedness offer securities law protections against fraud and misrepresentation.

DERIVATIVE INSTRUMENTS

In addition to the asset-backed securities, CBOs, CLOs and other CDOs and mortgage-related securities (including tiered index bonds and inverse floaters) which may be purchased by the Funds, the Funds may utilize certain other financial instruments with performance derived from the performance of an underlying asset (“derivatives”). The Funds might not employ any of the strategies described below, and no assurance can be given that any strategy used will succeed.

The Funds may purchase and write call and put options on securities, securities indices and on foreign currencies, and enter into futures contracts and use options on futures contracts. The Funds also may enter into swap agreements with other institutional investors with respect to corporate securities, foreign currencies, interest rates, and securities indices, to name just a few of the various types of swap transactions. The Funds may use these techniques to hedge against changes in interest rates, foreign currency exchange rates or securities prices or as part of their overall investment strategies. Each Fund will maintain designated assets consisting of cash, U.S. Government securities, equity securities or other liquid, unencumbered assets that are permitted under applicable laws and regulations to be used for this purpose (including net proceeds from purchases and redemptions of Fund shares that have not settled but are expected to timely settle in the usual way), marked-to-market daily (or, as permitted by applicable

Page 17

Table of Contents

regulation, enter into certain offsetting positions), to cover its obligations under options, futures contracts and swap agreements to avoid leveraging the Fund. The value of some derivative investments in which the Funds invest may be particularly sensitive to changes in prevailing interest rates or securities prices. A Fund’s ability to successfully utilize these instruments may depend in part on the Adviser’s ability to forecast correctly the movement of interest rates, securities prices and other economic factors. Should the Adviser incorrectly forecast those factors, and take positions in derivative instruments contrary to prevailing market trends, the Funds could lose value and experience substantial volatility. A Fund may invest up to 15% of its total assets in premiums and margins on options and futures, except for the AlphaTrak 500 and Strategic Income Funds that may invest at a higher level otherwise consistent with the Prospectus, this SAI and applicable law.

The Funds may buy or sell interest rate futures contracts, options on interest rate futures contracts and options on debt securities for the purpose of hedging against changes in the value of securities which a Fund owns or anticipates purchasing due to anticipated changes in interest rates. The Funds also may engage in currency exchange transactions by means of buying or selling foreign currency on a spot basis, entering into forward foreign currency exchange contracts, and buying and selling foreign currency options, futures and options on futures. Foreign currency exchange transactions may be entered into for the purpose of hedging against foreign currency exchange risk arising from the Funds’ investment or anticipated investment in securities denominated in foreign currencies.

OPTIONS ON SECURITIES AND ON SECURITIES INDEXES: A Fund may purchase put options on securities to seek to protect holdings in an underlying or related security against a substantial decline in market value. A Fund may purchase call options on securities to seek to protect against substantial increases in prices of securities the Fund intends to purchase pending its ability to invest in such securities in an orderly manner. A Fund may sell put or call options 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 which is sold. A Fund may write a call or put option only if the option is “covered” by the Fund’s holding a position in the underlying securities or by other means which would permit immediate satisfaction of the Fund’s obligation as writer of the option. 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 purchase and writing of options involves certain risks. 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 securities above the sum of the premium and exercise price, but, as long as its obligation as a writer continues, has retained the risk of loss should the price of the underlying securities 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 in order to terminate its obligation under the option and must deliver the underlying securities 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, in the case of a put, remains equal to or greater than the exercise price or, in the case of a call, remains less than or equal to the exercise price, 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. There can be no assurance that a liquid market will exist when a Fund seeks to close out an option position. Furthermore, if trading restrictions or suspensions are imposed on the options markets, a Fund may be unable to close out a position.

Risks Associated with Options on Securities and Indexes . As mentioned above, there are several risks associated with transactions in options on securities and on indexes. For example, there are significant differences between the securities and options markets that could result in an imperfect correlation between these markets, causing a given transaction not to achieve its objectives. A decision as to whether, when and how to use options involves the exercise of skill and judgment, and even a well-conceived transaction may be unsuccessful to some degree because of market behavior or unexpected events.

There can be no assurance that a liquid market will exist when a Fund seeks to close out an option position. If a Fund were unable to close out an option that it had purchased on a security, it would have to exercise the option in order to realize any profit or the option may expire worthless. If a 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 expired without exercise.

If trading were suspended in an option purchased by a 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.

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS: . A Fund may use interest rate, foreign currency or index futures contracts, as specified for that Fund in the Prospectus. An interest rate, 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, 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

Page 18

Table of Contents

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 these securities is made. A public market exists in futures contracts covering a number of indexes as well as financial instruments and foreign currencies, including but not limited to: the S&P 500; the S&P 100; the S&P Midcap 400; the Nikkei 225; the NYSE composite; U.S. Treasury bonds; U.S. Treasury notes; 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 Euro. It is expected that other futures contracts will be developed and traded by the Funds in the future.

A Fund may purchase and write call and put futures options. 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.

Each Fund will use futures contracts and options on futures contracts in accordance with the applicable rules of the CFTC under which the Trust and the Funds avoid being deemed a “commodity pool” and the Adviser being deemed a “commodity pool operator.” Because of these plans, the Funds have claimed the applicable exemptions under CFTC Rules and are not registered as commodity pool operators. Accordingly, each Fund intends generally to limit its use of futures contracts and futures options as described below under “Limitations on Use of Futures and Futures Options.”

The Funds generally will use futures for hedging purposes only. The A LPHA T RAK 500 F UND uses futures in an effort to achieve total return greater than the S&P 500 Index (and as such, hedges S&P 500 Index exposure), as described in the Prospectus. With respect to hedging transactions, for example, a Fund might use futures contracts to hedge against anticipated changes in interest rates that might adversely affect either the value of the Fund’s securities or the price of the securities which the Fund intends to purchase. A Fund’s hedging activities may include sales of futures contracts as an offset against the effect of expected increases in interest rates, and purchases of futures contracts as an offset against the effect of expected declines in interest rates. Although other techniques could be used to reduce a Fund’s exposure to interest rate fluctuations, the Fund may be able to hedge its exposure more effectively and perhaps at a lower cost by using futures contracts and futures options.

A 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. The Funds might, but do not expect to, engage in futures trading based on tangible assets.

When a purchase or sale of a futures contract is made by a Fund, the Fund is required to deposit with its custodian (or broker, if legally permitted) a specified amount of assets determined to be liquid by the Adviser in accordance with procedures established by the Board of Trustees (“initial margin”). 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 which is returned to the Fund upon termination of the contract, assuming all contractual obligations have been satisfied. Each Fund expects to earn interest income on its initial margin deposits. A futures contract held by a 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 a 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. In computing daily net asset value, each Fund will mark to market its open futures positions.

A Fund is also 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, generally these 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). 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 must also be included in these calculations.

The Funds may write covered straddles 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 Funds’ immediate obligations. A 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

Page 19

Table of Contents

call is higher than that of the put. In such cases, the Funds will also designate liquid assets equivalent to the amount, if any, by which the put is “in the money.”

Limitations on Use of Futures and Futures Options . The Funds generally will enter into positions in futures contracts and related options only for hedging purposes. With respect to positions in futures and related options that do not constitute hedging positions, a Fund will only enter into a futures contract or futures option contract to the extent permitted by the regulations of the CFTC and so that the aggregate net notional value or obligation of all futures contracts does not exceed the liquidation value of the Fund’s portfolio, after taking into account unrealized profits and losses. This means that, with respect to forwards and futures that are not contractually required to settle for cash, a Fund must cover its open contract positions by setting aside liquid assets equal to the contracts’ full notional value. With respect to forwards and futures that are contractually required to settle for cash, a Fund may, however, instead set aside liquid assets in an amount equal to the Fund’s daily marked-to-market net obligation (that is, any net liability) rather than the notional value. Using this net liability or market value to determine the amount of liquid assets to set aside allows a Fund to employ greater leverage.

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. There is no other percentage limitation on a Fund’s use of options, futures and options thereon, except for the limitation on foreign currency option contracts described below.

When purchasing a futures contract, a Fund will designate (and mark-to-market on a daily basis) assets determined to be liquid by the Adviser in accordance with procedures established by the Board of Trustees, that, when added to the amounts deposited with (or for the benefit of) a futures commission merchant as margin, are equal to the market value of the futures contract as described above. Alternatively, the Fund may “cover” its position by purchasing a put option on the same futures contract with a strike price as high or higher than the price of the contract held by the Fund.

When selling a futures contract, a Fund will designate (and mark-to-market on a daily basis) assets determined to be liquid by the Adviser in accordance with procedures established by the Board of Trustees that are equal to the market value of the instruments underlying the contract, or the related liability as described above. 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 Trust’s custodian).

When selling a call option on a futures contract, a Fund will maintain with its custodian (and mark-to-market on a daily basis) assets determined to be liquid by the Adviser in accordance with procedures established by the Board of Trustees, that, when added to the amounts deposited with (or for the benefit of) a futures commission merchant as margin, equal the total market value of the futures contract underlying the call option as described above. 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, a Fund will maintain with its custodian (and mark-to-market on a daily basis) assets determined to be liquid by the Adviser in accordance with procedures established by the Board of Trustees, that equal the purchase price of the futures contract, less any margin on deposit. 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 the same or higher 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 establish and collateralize or cover a 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 a 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 a Fund’s portfolio securities. Thus, the use of a longer-term security may require a 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 the Prospectus.

The requirements for qualification as a regulated investment company also may limit the extent to which a Fund may enter into futures, futures options or forward contracts. See “Dividends and Tax Status.”

Risks Associated with Futures and Futures Options . There are several risks 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. There can be no guarantee that there will be a correlation between price movements in the hedging vehicle and in the Fund securities being hedged. In addition, there are significant differences between the securities and futures markets that could result in an imperfect correlation between the markets, causing a given hedge not to achieve its objectives. 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, and even a well-conceived hedge may be unsuccessful to some degree because of market behavior or unexpected interest rate trends.

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.

There can be no assurance that a liquid market will exist at a time when a Fund seeks to close out a futures contract or a futures option position, and that Fund would remain obligated to meet margin requirements until the position is closed. In addition, many of the contracts discussed above 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.

Additional Risks of Options on Securities, Futures Contracts, Options on Futures Contracts, and Forward Currency Exchange Contracts and Options Thereon . Options on securities, futures contracts, options on futures contracts, and options on 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 Trust’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 . The Funds may enter into various swap agreements, including (but not limited to) credit default, interest rate, total return, index and currency exchange rate swap agreements. These transactions attempt to obtain a particular return when it is considered desirable to do so, possibly at a lower cost to a Fund than if the Fund had invested directly in an instrument that yielded that desired return. Swap agreements are 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. Forms of swap agreements include interest rate caps, under 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.

Most swap agreements entered into by the Funds calculate the obligations of the parties to the agreement on a “net basis.” Consequently, a 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”). A Fund’s current obligations under a swap agreement will be accrued daily (offset against any amounts owing to the Fund) and any accrued but unpaid net amounts owed to a swap counterparty will be covered by the maintenance of a designated account consisting of assets determined to be liquid by the Adviser in accordance with procedures established by the Board of Trustees, 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. Swap agreements are subject to the Funds’ overall limit that no more than 15% of net assets may be invested in illiquid securities, although a swap agreement may be deemed to be liquid pursuant to policies approved by the Funds’ Board of Trustees. A 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 assets at time of purchase.

Whether a Fund’s use of swap agreements will be successful in furthering its investment objectives will depend on the Adviser’s ability 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. Whether a particular swap is liquid is assessed on a case by case basis under guidelines and standards established by the Fund’s Board of Trustees. Moreover, a 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 Funds 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 Funds’ repurchase agreement guidelines). Certain restrictions imposed on the Funds by the Internal Revenue Code of 1986, as amended (the “Code”) may limit the Funds’ ability to use swap agreements. The swaps market is largely unregulated. It is possible that developments in the swaps market, including potential government regulation, could adversely affect a Fund’s ability to terminate existing swap agreements or to realize amounts to be received under such agreements. There can be no assurance that a Fund’s use of swap agreements will assist it in meeting its investment objectives.

Certain swap agreements are exempt from most provisions of the Commodity Exchange Act (“CEA”) and, therefore, are not regulated as futures or commodity option transactions under the CEA, pursuant to regulations approved by the CFTC. To qualify for this exemption, a swap agreement must be entered into by “eligible participants,” which includes the following, provided the participants’ total assets exceed established levels: a bank or trust company, savings association or credit union, insurance company, investment company subject to regulation under the 1940 Act, commodity pool, corporation, partnership, proprietorship, organization, trust or other entity, employee benefit plan, governmental entity, broker-dealer, futures commission merchant, natural person, or regulated foreign person. To be eligible, natural persons and most other entities must have total assets exceeding $10 million; commodity pools and employee benefit plans must have assets exceeding $5 million. In addition, an eligible swap transaction must meet three conditions. First, the swap agreement may not be part of a fungible class of agreements that are standardized as to their material economic terms. Second, the creditworthiness of parties with actual or potential obligations under the swap agreements must be a material consideration in entering into or determining the terms of the swap agreement, including pricing, cost or credit enhancement terms. Third, swap agreements may not be entered into and traded on or through a multilateral transaction execution facility.

This exemption is not exclusive, and participants may continue to rely on existing exclusions for swaps, such as the Policy Statement issued in July 1989 which recognized a safe harbor for swap transactions from regulation as futures or commodity option transactions under the CEA or its regulations. The Policy Statement applies to swap transactions settled in cash that (1) have individually tailored terms, (2) lack exchange-style offset and the use of a clearing organization or margin system, (3) are undertaken in conjunction with a line of business, and (4) are not marketed to the public.

CREDIT DEFAULT SWAP CONTRACTS: Each 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 no event of default by a selected entity (or entities) has occurred. In the event of default, the seller must pay the buyer the “par value” (full notional value) of the reference obligation in exchange for the reference obligation. The Fund may be either the buyer or seller in the transaction. If the Fund is a buyer and no event of default occurs, the Fund loses its investment and recovers nothing. However, if an event of default occurs, the buyer receives full notional value for 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, provided there is no default event. If an event of default occurs, the seller may pay the notional value of the reference obligation. The value of the reference obligation received by the seller, coupled with the periodic payments previously received may be less than the full notional value it pays to the buyer, resulting in a loss of value to the Fund. Credit default swaps involve greater risks than if the Fund had invested in the reference obligation directly. In addition to general market risks, credit default swaps are subject to risks such as but not limited to illiquidity risk, counterparty risk and credit risks.

TOTAL RETURN SWAP CONTRACTS: Each Fund may enter into total return swap agreements. Total Return Swap is the generic name for any non traditional swap where one party agrees to pay the other the "total return" of a defined underlying asset, usually in return for receiving a stream of LIBOR based cash flows. The Total Return Swap may be applied to any underlying asset but is most commonly used with equity indices, single stocks, bonds and defined portfolios of loans and mortgages. The Total Return Swap is a mechanism for the user to accept the economic benefits of asset ownership without utilizing the balance sheet. The other leg of the swap, usually LIBOR, is spread to reflect the non-balance sheet nature of the product. Total Return Swaps can be designed with any underlying asset agreed between two parties. No notional amounts are exchanged with Total Return Swaps.

STRUCTURED NOTES : 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 a 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.

FOREIGN CURRENCY OPTIONS AND RELATED RISKS : The Funds may take positions in options on foreign currencies to hedge against the risk of foreign exchange rate fluctuations on foreign securities the Funds hold in their portfolios or intend to purchase. For example, if a Fund were to enter into a contract to purchase securities denominated in a foreign currency, it could effectively fix the maximum U.S. dollar cost of the securities by purchasing call options on that foreign currency. Similarly, if a Fund held securities denominated in a foreign currency and anticipated a decline in the value of that currency against the U.S. dollar, it could hedge against such a decline by purchasing a put option on the currency involved. The markets in foreign currency options are relatively new, and a Fund’s ability to establish and close out positions in such options is subject to the maintenance of a liquid secondary market. There can be no assurance that a liquid secondary market will exist for a particular option at any specific time. In addition, options on foreign currencies are affected by all of those factors that influence foreign exchange rates and investments generally.

No Fund will enter into foreign currency option contracts if the premiums on such options exceed 5% of the Fund’s total assets.

The quantities of currencies underlying option contracts represent odd lots in a market dominated by transactions between banks, and as a result extra transaction costs may be incurred upon exercise of an option.

There is no systematic reporting of last sale information for foreign currencies or any regulatory requirement that quotations be firm or revised on a timely basis. Quotation information is generally representative of very large transactions in the interbank market and may not reflect smaller transactions where rates may be less favorable. Option markets may be closed while round-the-clock interbank currency markets are open, and this can create price and rate discrepancies.

RISKS OF OPTIONS TRADING : The Funds may effectively terminate their rights or obligations under options by entering into closing transactions. Closing transactions permit a Fund to realize profits or limit losses on its options positions prior to the exercise or expiration of the option. The value of a foreign currency option depends on the value of the underlying currency relative to the U.S. dollar. Other factors affecting the value of an option are the time remaining until expiration, the relationship of the exercise price to market price, the historical price volatility of the underlying currency and general market conditions. As a result, changes in the value of an option position may have no relationship to the investment merit of a foreign security. Whether a profit or loss is realized on a closing transaction depends on the price movement of the underlying currency and the market value of the option.

Options normally have expiration dates of up to nine months. The exercise price may be below, equal to or above the current market value of the underlying currency. Options that expire unexercised have no value, and a Fund will realize a loss of any premium paid and any transaction costs. Closing transactions may be effected only by negotiating directly with the other party to the option contract, unless a secondary market for the options develops. Although the Funds intend to enter into foreign currency options only with dealers which agree to enter into, and which are expected to be capable of entering into, closing transactions with the Funds, there can be no assurance that a Fund will be able to liquidate an option at a favorable price at any time prior to expiration. In the event of insolvency of the counter-party, a Fund may be unable to liquidate a foreign currency option. Accordingly, it may not be possible to effect closing transactions with respect to certain options, with the result that a Fund would have to exercise those options that it had purchased in order to realize any profit.

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS : The Funds may use forward contracts to protect against uncertainty in the level of future exchange rates. The Funds will not speculate with forward contracts or foreign currency exchange rates.

A Fund may enter into forward contracts with respect to specific transactions. For example, when a Fund enters into a contract for the purchase or sale of a security denominated in a foreign currency, or when a Fund anticipates the receipt in a foreign currency of dividend or interest payments on a security that it holds, the Fund may desire to “lock” in the U.S. dollar price of the security or the U.S. dollar equivalent of the payment, by entering into a forward contract for the purchase or sale, for a fixed amount of U.S. dollars or foreign currency, of the amount of foreign currency involved in the underlying transaction. A Fund will thereby be able to protect itself against a possible loss resulting from an adverse change in the relationship between the currency exchange rates during the period between the date on which the security is purchased or sold, or on which the payment is declared, and the date on which such payments are made or received.

A Fund also may use forward contracts in connection with portfolio positions to lock in the U.S. dollar value of those positions, to increase the Fund’s exposure to foreign currencies that the Adviser believes may rise in value relative to the U.S. dollar or to shift the Fund’s exposure to foreign currency fluctuations from one country to another. For example, when the Adviser believes that the currency of a particular foreign country may suffer a substantial decline relative to the U.S. dollar or another currency, it may enter into a forward contract to sell the amount of the former foreign currency approximating the value of some or all of the Funds’ portfolio securities denominated in such foreign currency. This investment practice generally is referred to as “cross-hedging” when another foreign currency is used.

Page 23

Table of Contents

The precise matching of the forward contract amounts and the value of the securities involved will not generally be possible because the future value of such securities in foreign currencies will change as a consequence of market movements in the value of those securities between the date the forward contract is entered into and the date it matures. Accordingly, it may be necessary for a Fund to purchase additional foreign currency on the spot ( i.e. , cash) market (and bear the expense of such purchase) if the market value of the security is less than the amount of foreign currency the Fund is obligated to deliver and if a decision is made to sell the security and make delivery of the foreign currency. Conversely, it may be necessary to sell on the spot market some of the foreign currency received upon the sale of the portfolio security if its market value exceeds the amount of foreign currency the Fund is obligated to deliver. The projection of short-term currency market movements is extremely difficult, and the successful execution of a short-term hedging strategy is highly uncertain. Forward contracts involve the risk that anticipated currency movements will not be accurately predicted, causing the Fund to sustain losses on these contracts and transaction costs. A Fund may enter into forward contracts or maintain a net exposure to such contracts only if (1) the consummation of the contracts would not obligate the Fund to deliver an amount of foreign currency in excess of the value of the Fund’s portfolio securities or other assets denominated in that currency or (2) the Fund designates liquid assets in an amount not less than the value of the Fund’s total assets committed to the consummation of the contracts. Under normal circumstances, consideration of the prospect for currency parities will be incorporated into the longer-term investment decisions made with regard to overall diversification strategies. However, the Adviser believes it is important to have the flexibility to enter into such forward contracts when it determines that the best interests of a Fund will be served.

At or before the maturity date of a forward contract that requires a Fund to sell a currency, the Fund either may sell a portfolio security and use the sale proceeds to make delivery of the currency or retain the security and offset its contractual obligation to deliver the currency by purchasing a second contract pursuant to which the Fund will obtain, on the same maturity date, the same amount of the currency that it is obligated to deliver. Similarly, a Fund may close out a forward contract requiring it to purchase a specified currency by entering into a second contract entitling it to sell the same amount of the same currency on the maturity date of the first contract. The Fund would realize a gain or loss as a result of entering into such an offsetting forward contract under either circumstance to the extent the exchange rate between the currencies involved moved between the execution dates of the first and second contracts.

The cost to the Fund of engaging in forward contracts varies with factors such as the currencies involved, the length of the contract period and the market conditions then prevailing. Because forward contracts are usually entered into on a principal basis, no fees or commissions are involved. The use of forward contracts does not eliminate fluctuations in the prices of the underlying securities the Fund owns or intends to acquire, but it does fix a rate of exchange in advance. In addition, although forward contracts limit the risk of loss due to a decline in the value of the hedged currencies, at the same time they limit any potential gain that might result should the value of the currencies increase.

Although the Funds value their assets daily in terms of U.S. dollars, they do not intend to convert holdings of foreign currencies into U.S. dollars on a daily basis. The Funds may convert foreign currency from time to time, and investors should be aware of the costs of currency conversion. Although foreign exchange dealers do not charge a fee for conversion, they do realize a profit based on the difference between the prices at which they are buying and selling various currencies. Thus, a dealer may offer to sell a foreign currency to a Fund at one rate, while offering a lesser rate of exchange should the Fund desire to resell that currency to the dealer.

FOREIGN SECURITIES

Each Fund (other than the S TRATEGIC I NCOME F UND , which is not subject to this limitation) may invest up to 25% of its total assets in securities of foreign issuers that are denominated in U.S. dollars. Investments in securities of foreign issuers that are not denominated in U.S. dollars by the Funds (other than the S TRATEGIC I NCOME F UND ) will be limited to a maximum of 15% of each Fund’s total assets. The S TRATEGIC I NCOME F UND may invest up to 30% of its total assets in securities of foreign issuers that are not denominated in U.S. dollars. Foreign economies may differ from the U.S. economy; individual foreign companies may differ from domestic companies in the same industry; and foreign currencies may be stronger or weaker than the U.S. dollar. The Adviser believes that the ability to invest abroad will enable the Funds to take advantage of these differences when they are favorable.

Fixed-income securities that may be purchased by the Funds include debt obligations issued or guaranteed by foreign governments, their subdivisions, agencies or instrumentalities, or by supranational entities that have been constituted by the governments of several countries to promote economic development, such as The World Bank and The Asian Development Bank. Foreign investment in certain foreign government debt is restricted or controlled to varying degrees.

The Funds may also invest in fixed-income securities of issuers located in emerging foreign markets; provided, however, that the Funds may invest up to only 10% of their total assets in emerging foreign market securities. Emerging markets generally include every country in the world other than the United States, Canada, Japan, Australia, Malaysia, New Zealand, Hong Kong, Singapore and most Western European countries. In determining what countries constitute emerging markets, the Adviser will consider, among other things, data, analysis and classification of countries published or disseminated by the International Bank for Reconstruction

Page 24

Table of Contents

and Development (the “World Bank”) and the International Financial Corporation. Currently, investing in many emerging markets may not be desirable or feasible, because of the lack of adequate custody arrangements for a Fund’s assets, overly burdensome repatriation and similar restrictions, the lack of organized and liquid securities markets, unacceptable political risks or other reasons. As opportunities to invest in securities in emerging markets develop, the Funds expect to expand and further broaden the group of emerging markets in which they invest.

From time to time, emerging markets have offered the opportunity for higher returns in exchange for a higher level of risk. Accordingly, the Adviser believes that each Fund’s ability to invest in emerging markets throughout the world may enable the achievement of results superior to those produced by funds, with similar objectives to those of the Funds that invest solely in securities in developed markets. There is no assurance that any Fund will achieve these results.

The Funds may invest in the following types of emerging market fixed-income securities: (a) fixed-income securities issued or guaranteed by governments, their agencies, instrumentalities or political subdivisions, or by government-owned, controlled or sponsored entities, including central banks (collectively, “Sovereign Debt”), including Brady Bonds (described below); (b) interests in issuers organized and operated for the purpose of restructuring the investment characteristics of Sovereign Debt; (c) fixed-income securities issued by banks and other business entities; and (d) fixed-income securities denominated in or indexed to the currencies of emerging markets. Fixed-income securities held by the Funds may take the form of bonds, notes, bills, debentures, bank debt obligations, short-term paper, loan participations, assignments and interests issued by entities organized and operated for the purpose of restructuring the investment characteristics of any of the foregoing. There is no requirement with respect to the maturity of fixed-income securities in which the Funds may invest.

The Funds may invest in Brady Bonds and other Sovereign Debt of countries that have restructured or are in the process of restructuring Sovereign Debt pursuant to the Brady Plan. “Brady Bonds” are debt securities issued under the framework of the Brady Plan, an initiative announced by former U.S. Treasury Secretary Nicholas F. Brady in 1989 as a mechanism for debtor nations to restructure their outstanding external commercial bank indebtedness. In restructuring its external debt under the Brady Plan framework, a debtor nation negotiates with its existing bank lenders as well as multilateral institutions such as the World Bank and the International Monetary Fund (“IMF”). The Brady Plan framework, as it has developed, contemplates the exchange of commercial bank debt for newly issued Brady Bonds. Brady Bonds may also be issued in respect of new money being advanced by existing lenders in connection with the debt restructuring. The World Bank and/or the IMF support the restructuring by providing funds pursuant to loan agreements or other agreements which enable the debtor nation to collateralize the new Brady Bonds or to repurchase outstanding bank debt at a discount.

Emerging market fixed-income securities generally are considered to be of a credit quality below investment grade, even though they often are not rated by any nationally recognized statistical rating organizations. Investment in emerging market fixed-income securities will be allocated among various countries based upon the Adviser’s analysis of credit risk and its consideration of a number of factors, including: prospects for relative economic growth among the different countries in which the Funds may invest; expected levels of inflation; government policies influencing business conditions; the outlook for currency relationships; and the range of the individual investment opportunities available to international investors. The Adviser’s emerging market sovereign credit analysis includes an evaluation of the issuing country’s total debt levels, currency reserve levels, net exports/imports, overall economic growth, level of inflation, currency fluctuation, political and social climate and payment history. Particular fixed-income securities will be selected based upon credit risk analysis of potential issuers, the characteristics of the security and interest rate sensitivity of the various debt issues available with respect to a particular issuer, analysis of the anticipated volatility and liquidity of the particular debt instruments, and the tax implications to the Fund. The emerging market fixed-income securities in which the Funds may invest are not subject to any minimum credit quality standards.

Investments in emerging market and other foreign securities involve certain risk considerations not typically associated with investing in securities of U.S. issuers, including: (a) currency devaluations, other currency exchange rate fluctuations, or the imposition of currency controls; (b) political uncertainty and instability, including circumstances that lead to scenarios such as but not limited to the privatization and confiscation of invested assets; (c) more substantial government involvement in the economy; (d) higher rates of inflation; (e) less government supervision and regulation of the securities markets and participants in those markets; (f) controls on foreign investment and limitations on repatriation of invested capital and on the Fund’s ability to exchange local currencies for U.S. dollars; (g) greater price volatility, substantially less liquidity and significantly smaller capitalization of securities markets; (h) absence of uniform accounting and auditing standards; (i) generally higher commission expenses; (j) delay in settlement of securities transactions; and (k) greater difficulty in enforcing shareholder rights and remedies.

ILLIQUID SECURITIES

A Fund may not invest more than 15% of its net assets in repurchase agreements which have a maturity of longer than seven days or in other illiquid securities, including securities that are illiquid by virtue of the absence of a readily available market (either within or outside of the United States) or legal or contractual restrictions of resale. Historically, illiquid securities

Page 25

Table of Contents

have included securities subject to contractual or legal restrictions on resale because they have not been registered under the Securities Act, securities which are otherwise not readily marketable and repurchase agreements have a maturity of longer than seven days. Securities which have not been registered under the Securities Act generally are referred to as private placements or restricted securities and are purchased directly from the issuer or in the secondary market. Mutual funds do not typically hold a significant amount of these restricted or other illiquid securities because of the potential for delays on resale and uncertainty in valuation. Limitations on resale may have an adverse effect on the marketability of portfolio securities and a mutual fund might be unable to dispose of restricted or other illegal securities promptly or at reasonable prices and might thereby experience difficulty 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. Currently the Funds may invest in securities issued in private placements. The Funds also may invest in mezzanine securities which are placed between debt and equity in a company’s capital structure. These securities are typically subordinated debt instruments for late stage venture and mature companies and may offer income through a current coupon and equity participation through a warrant. In addition to being subject to credit risk, mezzanine securities are generally considered less liquid.

Over a period of years, however, a large institutional market has developed for certain securities that are not registered under the Securities Act, including repurchase agreements, commercial paper, foreign securities, municipal securities, convertible securities and corporate bonds and notes. Institutional investors depend on an efficient institutional market in which the unregistered security can be readily resold or on an issuer’s ability to honor a demand for repayment. The fact that there are contractual or legal restrictions on resale to the general public or to certain institutions may not be indicative of the liquidity of such investments.

Rule 144A under the Securities Act allows for a broader institutional trading market for securities otherwise subject to restriction on resale to the general public. Rule 144A established a “safe harbor” from the registration requirements of the Securities Act for resales of certain securities to qualified institutional buyers. The Adviser anticipates that the market for certain restricted securities such as institutional commercial paper and foreign securities will expand further as a result of this rule and the development of automated systems for the trading, clearance and settlement of unregistered securities of domestic and foreign issuers, such as the PORTAL System sponsored by the National Association of Securities Dealers, Inc.

Restricted securities eligible for resale pursuant to Rule 144A under the Securities Act and commercial paper for which there is a readily available market will not be deemed to be illiquid. The Adviser will monitor the liquidity of such restricted securities subject to the supervision of the Trustees. In reaching liquidity decisions, the Adviser will consider the following factors, among other considerations: (1) the frequency of trades and quotes for the security; (2) the number of dealers wishing to purchase or sell the security and the number of other potential purchasers; (3) dealer undertakings to make a market in the security; and (4) the nature of the security and the nature of the marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of the transfer). In addition, in order for commercial paper that is issued in reliance on Section 4(2) of the Securities Act to be considered liquid, (i) it must be rated in one or two of the highest rating categories by at least two nationally recognized statistical rating organizations (“NRSRO”), or if only one NRSRO rates the securities, by that NRSRO, or, if unrated, be of comparable quality in the view of the Adviser, and (ii) it must not be “traded flat” ( i.e. , without accrued interest) or in default as to principal or interest. While the Adviser uses procedures to determine that certain Rule144A securities are liquid, market conditions may later affect that assessment adversely. Therefore, the Fund could potentially hold higher levels of illiquid securities than previously anticipated. Investing in Rule 144A securities could have the effect of increasing the level of Fund illiquidity to the extent that qualified institutional buyers become, for a time, uninterested in purchasing these securities. Repurchase agreements subject to demand are deemed to have a maturity equal to the notice period.

BORROWING AND LEVERAGE

The H IGH Y IELD B OND F UND and S TRATEGIC I NCOME F UND may borrow money to the extent permitted under the 1940 Act, and as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time. This means that, in general, these Funds may borrow money from banks for any purpose on a secured basis in an amount up to 1/3 of the Fund’s total assets. These Funds may also borrow for temporary administrative purposes on an unsecured basis in an amount not to exceed 5% of the Fund’s total assets.

The U LTRA S HORT B OND F UND , L OW D URATION B OND F UND , I NTERMEDIATE B OND F UND , T OTAL R ETURN B OND F UND and A LPHA T RAK 500 F UND each may borrow for temporary, emergency or investment purposes up to 5% of its total assets. This borrowing may be unsecured.

The provisions of the 1940 Act require a Fund to maintain continuous asset coverage (that is, total assets including borrowings, less liabilities exclusive of borrowings) of 300% of the amount borrowed, with an exception for borrowings not in excess of 5% of the Fund’s total assets made for temporary administrative purposes. Any borrowings for temporary administrative purposes in excess of the Fund’s total assets must maintain continuous asset coverage. If the 300% asset coverage should decline as a result of market fluctuations or other reasons, a Fund may be required to sell some of its portfolio holdings within three days to reduce debt and restore the 300% asset coverage, even though it may be disadvantageous from an investment standpoint to sell securities at that time.

Page 26

Table of Contents

Borrowing subjects a Fund to interest costs which may or may not be recovered by appreciation of the securities purchased, and can exaggerate the effect on net asset value of any increase or decrease in the market value of a Fund’s portfolio. This is the speculative factor known as leverage.

As noted above, a Fund also may enter into certain transactions, including reverse repurchase agreements, that can be viewed as constituting a form of borrowing or financing transaction by the Fund. To the extent a Fund covers its commitment under a reverse purchase agreement (or economically similar transaction) by the designation of assets determined in accordance with procedures adopted by the Trustees, equal in value to the amount of the Fund’s commitment to repurchase, such an agreement will not be considered a “senior security” by the Fund and therefore will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by the Funds. Borrowing will tend to exaggerate the effect on net asset value of any increase or decrease in the market value of a Fund’s portfolio. Money borrowed will be subject to interest costs which may or may not be recovered by appreciation of the securities purchased. A Fund also may be required to maintain minimum average balances in connection with such borrowing or to pay a commitment or other fee to maintain a line of credit; either of these requirements would increase the cost of borrowing over the stated interest rate.

Instead of borrowing, the Funds may, from time to time, participate in a program offered by ReFlow, LLC. ReFlow operates an auction program over the Internet (the “Auction Program”) through which it makes an alternative source of capital available to Participating Funds to allow the Participating Funds to satisfy some or all of their daily redemption requests. ReFlow makes the Auction Program available to eligible funds on an investment–blind basis, meaning that ReFlow stands ready to purchase and redeem shares of Participating Funds that submit successful bids without regard to their investment objectives or performance, and that, consistent with the terms of the Auction Program, it will buy shares of Participating Funds that submit successful bids and redeem such shares without regard to their investment objectives or performance. ReFlow will provide money to Participating Funds that submit successful bids in the auction by purchasing shares of the Funds. There is no assurance in participating in such a program either that the Funds will be successful during the Auction, or that ReFlow will have sufficient funds available to meet the Funds’ needs. The Funds’ Board of Trustees has approved the use of the ReFlow program in addition to or in lieu of borrowing.

One or more of the Funds that participate in the Auction Program may also impose a redemption fee on shares redeemed by shareholders within a certain period after purchase. Any redemption fees are described in the prospectus for the applicable Funds. A redemption fee is designed to facilitate portfolio management and offset transaction costs associated with short-term trading of Fund shares. A Fund's participation in ReFlow also is intended to facilitate portfolio management and minimize the need for the Fund to incur transaction costs. But ReFlow is structured to redeem shares of a participating Fund when other investors are purchasing shares, which may occur during the redemption fee period. For that reason, a Fund participating in the Auction Program will normally waive any redemption fee that otherwise would apply to shares redeemed by ReFlow through the Auction Program.

PORTFOLIO TURNOVER

Portfolio securities are sold whenever the Adviser believes it appropriate, regardless of how long the securities have been held. Portfolio turnover generally involves some expense to the Fund, including brokerage commissions, dealer markups and other transaction costs, and may result in the recognition of capital gains that may be distributed to shareholders. Generally, portfolio turnover over 100% is considered high and increases these costs. The Adviser does not view turnover as an important consideration in managing the Funds and does not strive to limit portfolio turnover. Each Fund’s investment program emphasizes active portfolio management with a sensitivity to short-term market trends and price changes in individual securities. Accordingly, each Fund may take frequent trading positions, resulting in portfolio turnover that may exceed the portfolio turnover of most investment companies of comparable size.

DEFENSIVE INVESTING

The Funds may engage in defensive investing, which is a deliberate, temporary shift in portfolio strategy that may be undertaken when markets start behaving in volatile or unusual ways. Depending on the Adviser’s analysis of the various markets and other considerations, the Funds may, for temporary defensive purposes, invest a substantial part or all of their assets in bonds of U.S. or foreign governments, cash, certificates of deposit, bankers’ acceptances, high-grade commercial paper, and repurchase agreements. Such investments may also be made for temporary purposes pending investment in other securities or following substantial new investment in a Fund. When the Funds have invested defensively in low risk, low return securities, they may not achieve their investment objectives. There is no assurance that the Funds will enter into a defensive strategy in the event of volatility or other unusual activity in the securities markets.
