Asset Coverage

To the extent required by SEC guidelines, if a transaction exposes the Fund to an obligation of another party it will either: (1) enter an offsetting (“covered”) position for the same type of financial asset; or (2) segregate cash or liquid securities on the books of either the custodian or the investment adviser with a value sufficient at all times to cover its potential obligations not covered. Assets used as cover or segregated cannot be sold while the position(s) requiring cover is open unless replaced with other appropriate assets. As a result, if a large portion of assets is segregated or committed as cover, it could impede portfolio management or the ability to meet redemption requests or other current obligations.  The types of transactions that may require asset coverage include (but are not limited to) reverse repurchase agreements, repurchase agreements, short sales, securities lending, forward contracts, options, forward commitments, futures contracts, when-issued securities, swap agreements, residual interest bonds and participation in revolving credit facilities.

Asset-Backed Securities (“ABS”)

ABS are collateralized by pools of automobile loans, educational loans, home equity loans, credit card receivables, equipment or automobile leases, commercial mortgage-backed securities (“MBS”), utilities receivables and secured or unsecured bonds issued by corporate or sovereign obligors, unsecured loans made to a variety of corporate commercial and industrial loan customers of one or more lending banks, or a combination of these bonds and loans. ABS are “pass through” securities, meaning that principal and interest payments made by the borrower on the underlying assets are passed through to the ABS holder. ABS are issued through special purpose vehicles that are bankruptcy remote from the issuer of the collateral. ABS are subject to interest rate risk and prepayment risk.   Some ABS may receive prepayments that can change their effective maturities.  Issuers of ABS may have limited ability to enforce the security interest in the underlying assets or may have no security in the underlying assets, and credit enhancements provided to support the securities, if any, may be inadequate to protect investors in the event of default. In addition, ABS may experience losses on the underlying assets as a result of certain rights provided to consumer debtors under federal and state law. The value of ABS may be affected by the factors described above and other factors, such as the availability of information concerning the pool and its structure, the creditworthiness of the servicing agent for the pool, the originator of the underlying assets or the entities providing credit enhancements and the ability of the servicer to service the underlying collateral. The value of ABS representing interests in a pool of utilities receivables may be adversely affected by changes in government regulations. While certain ABS may be insured as to the payment of principal and interest, this insurance does not protect the market value of such obligations or the Fund’s net asset value. The value of an insured security will be affected by the credit standing of its insurer.

Collateralized debt obligations (“CDOs”) and collateralized loan obligations (“CLOs”) are types of ABS that are backed solely by a pool of other debt securities.  CDOs and CLOs are typically issued in various classes with varying priorities.  The risks of an investment in a CDO or CLO depend largely on the type of the collateral securities and the class of the CDO or CLO in which the Fund invests.  In addition to interest rate, prepayment, default and other risks of ABS and fixed income securities, in general, CDOs and CLOs are subject to 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 Fund may invest in CDOs or CLOs that are subordinate to other classes, and the complex structure may produce disputes with the issuer or unexpected investment results.

Auction Rate Securities

Auction rate securities, such as auction preferred shares of closed-end investment companies, are preferred securities and debt securities with dividends/coupons based on a rate set at auction. The auction is usually held weekly for each series of a security, but may be held less frequently. The auction sets the rate, and securities may be bought and sold at the auction.  Provided that the auction mechanism is successful, auction rate securities normally permit the holder to sell the securities in an auction at par value at specified intervals. The dividend is reset by a "Dutch" auction in which bids are made by broker-dealers and other institutions for a certain amount of securities at a specified minimum yield. The dividend rate set by the auction is the lowest interest or dividend rate that covers all securities offered for sale. While this process is designed to permit auction rate securities to be traded at par value, there is the risk that an auction will fail due to insufficient demand for the securities. Security holders that submit sell orders in a failed auction may not be able to sell any or all of the shares for which they have submitted sell orders. Security holders may sell their shares at the next scheduled auction, subject to the same risk that the subsequent auction will not attract sufficient demand for a successful auction to occur. Broker-dealers may also try to facilitate secondary trading in the auction rate securities, although such secondary trading may be limited and may only be available for shareholders willing to sell at a discount.  Since mid-February 2008, existing markets for certain auction rate securities have become generally illiquid and investors have not been able to sell their securities through the regular auction process. It is uncertain, particularly in the near term, when or whether there will be a revival of investor interest in purchasing securities sold through auctions. In addition, there may be no active secondary markets for many auction rate securities. Moreover, auction rate securities that do trade in a secondary market may trade at a significant discount from the underlying liquidation or principle amount of the securities. Finally, there recently have been a number of governmental investigations and regulatory settlements involving certain broker-dealers with respect to their prior activities involving auction rate securities.

Valuations of such securities is highly speculative, however, dividends on auction rate preferred securities issued by a closed-end fund may be reported, generally on Form 1099, as exempt from federal income tax to the extent they are attributable to tax-exempt interest income earned by the Fund on the securities and distributed to holders of the preferred securities, provided that the preferred securities are treated as equity securities for federal income tax purposes, and the closed-end fund complies with certain requirements under the Code. Investments in auction rate preferred securities of closed-end funds are subject to limitations on investments in other U.S. registered investment companies, which limitations are prescribed by the 1940 Act.

Average Effective Maturity

Average effective maturity is a weighted average of all the maturities of bonds owned by the Fund. Average effective maturity takes into consideration all mortgage payments, puts and adjustable coupons.  In the event the Fund invests in multiple Portfolios, its average weighted maturity is the sum of its allocable share of the average weighted maturity of each of the Portfolios in which it invests, which is determined by multiplying the Portfolio’s average weighted maturity by the Fund’s percentage ownership of that Portfolio.

Borrowing for Investment Purposes

Successful use of a borrowing strategy depends on the investment adviser’s ability to predict correctly interest rates and market movements. There is no assurance that a borrowing strategy will be successful. Upon the expiration of the term of the Fund’s existing credit arrangement, the lender may not be willing to extend further credit to the Fund or may be willing to do so at an increased cost to the Fund. If the Fund is not able to extend its credit arrangement, it may be required to liquidate holdings to repay amounts borrowed from the lender. Borrowing to increase investments generally will exaggerate the effect on the Fund’s net asset value of any increase or decrease in the value of the security purchased with the borrowings. Successful use of a borrowing strategy depends on the investment adviser’s ability to predict correctly interest rates and market movements. There can be no assurance that the use of borrowings will be successful. In connection with its borrowings, the Fund will be required to maintain specified asset coverage with respect to such borrowings by both the 1940 Act and the terms of its credit facility with the lender.  The Fund may be required to dispose of portfolio investments on unfavorable terms if market fluctuations or other factors reduce the required asset coverage to less than the prescribed amount. Borrowings involve additional expense to the Fund.

Borrowing for Temporary Purposes

The Fund may borrow for temporary purposes (such as to satisfy redemption requests, to remain fully invested in advance of the settlement of share purchases, and to settle transactions).  The Fund typically makes any such borrowings pursuant to an umbrella credit facility to which most of the Eaton Vance funds have access.  The Fund’s ability to borrow under the credit facility is subject to its terms and conditions, which in some cases may limit the Fund’s ability to borrow under the facility.  The credit facility is subject to an annual renewal, which cannot be assured.  If the Fund does not have the ability to borrow for temporary purposes, it may be required to sell securities at inopportune times to meet short-term liquidity needs.  Borrowings involve additional expense to the Fund.

Build America Bonds

Build America Bonds are taxable municipal obligations issued pursuant to the American Recovery and Reinvestment Act of 2009 (the “Act”) or other legislation providing for the issuance of taxable municipal debt on which the issuer receives federal support. Enacted in February 2009, the Act authorizes state and local governments to issue taxable bonds on which, assuming certain specified conditions are satisfied, issuers may either (i) receive reimbursement from the U.S. Treasury with respect to its interest payments on the bonds (“direct pay” Build America Bonds); or (ii) provide tax credits to investors in the bonds (“tax credit” Build America Bonds). Unlike most other municipal obligations, interest received on Build America Bonds is subject to federal income tax and may be subject to state income tax. Under the terms of the Act, issuers of direct pay Build America Bonds are entitled to receive reimbursement from the U.S. Treasury currently equal to 35% (or 45% in the case of Recovery Zone Economic Development Bonds) of the interest paid. Holders of tax credit Build America Bonds can receive a federal tax credit currently equal to 35% of the coupon interest received. The Fund may invest in “principal only” strips of tax credit Build America Bonds, which entitle the holder to receive par value of such bonds if held to maturity. The Fund does not expect to receive (or pass through to shareholders) tax credits as a result of its investments.  The federal interest subsidy or tax credit continues for the life of the bonds. Build America Bonds are an alternative form of financing to state and local governments whose primary means for accessing the capital markets has been through issuance of tax-free municipal bonds. Build America Bonds can appeal to a broader array of investors than the high income U.S. taxpayers that have traditionally provided the market for municipal bonds. Build America Bonds may provide a lower net cost of funds to issuers. Pursuant to the terms of the Act, the issuance of Build America Bonds ceased on December 31, 2010.  As a result, the availability of such bonds is limited and the market for the bonds and/or their liquidity may be affected.

Call and Put Features on Obligations

Issuers of obligations may reserve the right to call (redeem) the obligations. If an issuer redeems an obligation with a call right during a time of declining interest rates, the holder of the obligation may not be able to reinvest the proceeds in securities providing the same investment return as provided by the securities redeemed. Some obligations may have “put” or “demand” features that allow early redemption by the holder. Longer term fixed-rate bonds may give the holder a right to request redemption at certain times (often annually after the lapse of an intermediate term). This “put” or “demand” feature enhances an obligation’s liquidity by shortening its effective maturity and enables the security to trade at a price equal to or very close to par. If a demand feature terminates prior to being exercised, the holder of the obligation would be subject to the longer maturity of the obligation, which could experience substantially more volatility.  Obligations with a “put” or “demand” feature are more defensive than conventional long term bonds (protecting to some degree against a rise in interest rates) while providing greater opportunity than comparable intermediate term bonds, because they can be retained if interest rates decline.

Cash Equivalents

Cash equivalents include short term, high quality, U.S. dollar denominated instruments such as commercial paper, certificates of deposit and bankers’ acceptances issued by U.S. or foreign banks, and Treasury bills and other obligations with a maturity of one year or less, including those issued or guaranteed by U.S. Government agencies and instrumentalities.  See “U.S. Government Securities” below. Certificates of deposit are certificates issued against funds deposited in a commercial bank, are for a definite period of time, earn a specified rate of return, and are normally negotiable. Bankers’ acceptances are short-term credit instruments used to finance the import, export, transfer or storage of goods. They are termed “accepted” when a bank guarantees their payment at maturity.

The obligations of foreign branches of U.S. banks may be general obligations of the parent bank in addition to the issuing branch, or may be limited by the terms of a specific obligation and by governmental regulation.  Payment of interest and principal upon these obligations may also be affected by governmental action in the country of domicile of the branch (generally referred to as sovereign risk). In addition, evidence of ownership of portfolio securities may be held outside of the U.S. and generally will be subject to the risks associated with the holding of such property overseas. Various provisions of U.S. law governing the establishment and operation of domestic branches do not apply to foreign branches of domestic banks. The obligations of U.S. branches of foreign banks may be general obligations of the parent bank in addition to the issuing branch, or may be limited by the terms of a specific obligation and by federal and state regulation as well as by governmental action in the country in which the foreign bank has its head office.

Cash equivalents are often acquired directly from the issuers thereof or otherwise are normally traded on a net basis (without commission) through broker-dealers and banks acting for their own account. Such firms attempt to profit from such transactions by buying at the bid price and selling at the higher asked price of the market, and the difference is customarily referred to as the spread. Cash equivalents may be adversely affected by market and economic events, such as a sharp rise in prevailing short-term interest rates; adverse developments in the banking industry, which issues or guarantees many money market securities; adverse economic, political or other developments affecting domestic issuers of money market securities; changes in the credit quality of issuers; and default by a counterparty.  These securities may be subject to federal income, state income and/or other taxes.  Instead of investing in cash equivalents directly, the Fund may invest in an affiliated money market fund (such as Eaton Vance Cash Reserves Fund, LLC, which is managed by Eaton Vance) or unaffiliated money market fund.

Collateralized Mortgage Obligations (“CMOs”)  

CMOs are backed by a pool of mortgages or mortgage loans.  The key feature of the CMO structure is the prioritization of the cash flows from the pool of mortgages among the several classes, or tranches, of the CMO, thereby creating a series of obligations with varying rates and maturities.  Senior CMO classes will typically have priority over residual CMOs as to the receipt of principal and or interest payments on the underlying mortgages.  CMOs also issue sequential and parallel pay classes, including planned amortization class and target amortization classes and fixed and floating rate CMO tranches.  CMOs issued by U.S. government agencies are backed by agency mortgages, while privately issued CMOs may be backed by either government agency mortgages or private mortgages.  Payments of principal and interest are passed through to each CMO tranche at varying schedules resulting in bonds with different coupons, effective maturities and sensitivities to interest rates. Parallel pay CMOs are structured to provide payments of principal on each payment date to more than one class, concurrently on a proportionate or disproportionate basis.  Sequential pay CMOs generally pay principal to only one class at a time while paying interest to several classes.  CMOs generally are secured by an assignment to a trustee under the indenture pursuant to which the bonds are issued as collateral consisting of a pool of mortgages. Payments with respect to the underlying mortgages generally are made to the trustee under the indenture. CMOs are designed to be retired as the underlying mortgages are repaid. In the event of sufficient early prepayments on such mortgages, the class or series of CMO first to mature generally will be retired prior to maturity. Therefore, although in most cases the issuer of CMOs will not supply additional collateral in the event of such prepayments, there will be sufficient collateral to secure CMOs that remain outstanding. Floating rate CMO tranches carry interest rates that are tied in a fixed relationship to an index subject to an upper limit, or "cap," and sometimes to a lower limit, or "floor." CMOs may be less liquid and may exhibit greater price volatility than other types of mortgage- or asset-backed securities.

Commercial Mortgage-Backed Securities (“CMBS”)

CMBS include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property, such as hotels, office buildings, retail stores, hospitals and other commercial buildings. CMBS may have a lower repayment uncertainty than other mortgage-related securities because commercial mortgage loans generally prohibit or impose penalties on prepayment of principal.  The risks of investing in CMBS reflect the risks of investing in the real estate securing the underlying mortgage loans, including the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payment, and the ability of a property to attract and retain tenants. CMBS may be less liquid and may exhibit greater price volatility than other types of mortgage- or asset-backed securities.

Although common stocks have historically generated higher average returns than fixed-income securities over the long term and particularly during periods of high or rising concerns about inflation, common stocks also have experienced significantly more volatility in returns and may not maintain their real value during inflationary periods. An adverse event, such as an unfavorable earnings report, may depress the value of a particular common stock. Also, the prices of common stocks are sensitive to general movements in the stock market and a drop in the stock market may depress the price of common stocks. Common stock prices fluctuate for many reasons, including changes in investors’ perceptions of the financial condition of an issuer or the general condition of the relevant stock market, or when political or economic events affecting the issuer occur. In addition, common stock prices may be sensitive to rising interest rates as the costs of capital rise and borrowing costs increase.

Convertible Securities

A convertible security is a bond, debenture, note, preferred security, or other security that entitles the holder to acquire common stock or other equity securities of the same or a different issuer.   A convertible security entitles the holder to receive interest paid or accrued on debt or the dividend paid on preferred securities until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to nonconvertible income securities in that they ordinarily provide a stable stream of income with generally higher yields than those of common stocks of the same or similar issuers, but lower yields than comparable nonconvertible securities. The value of a convertible security is influenced by changes in interest rates, with investment value declining as interest rates increase and increasing as interest rates decline. The credit standing of the issuer and other factors also may have an effect on the convertible security’s investment value. A convertible security ranks senior to common stock in a corporation’s capital structure but are usually subordinated to comparable nonconvertible securities.  Convertible securities may be purchased for their appreciation potential when they yield more than the underlying securities at the time of purchase or when they are considered to present less risk of principal loss than the underlying securities. Generally speaking, the interest or dividend yield of a convertible security is somewhat less than that of a non-convertible security of similar quality issued by the same company.  A convertible security may be subject to redemption at the option of the issuer at a price established in the convertible security’s governing instrument.

Convertible securities are issued and traded in a number of securities markets. Even in cases where a substantial portion of the convertible securities held by the Fund are denominated in U.S. dollars, the underlying equity securities may be quoted in the currency of the country where the issuer is domiciled. As a result, fluctuations in the exchange rate between the currency in which the debt security is denominated and the currency in which the share price is quoted will affect the value of the convertible security.  With respect to convertible securities denominated in a currency different from that of the underlying equity securities, the conversion price may be based on a fixed exchange rate established at the time the securities are issued, which may increase the effects of currency risk.

Holders of convertible securities generally have a claim on the assets of the issuer prior to the common stockholders but may be subordinated to other debt securities of the same issuer. Certain convertible debt securities may provide a put option to the holder, which entitles the holder to cause the securities to be redeemed by the issuer at a premium over the stated principal amount of the debt securities under certain circumstances.

Certain convertible securities may include loss absorption characteristics that make the securities more equity like.  This is particularly true in the financial services sector.  While loss absorption language is relatively rare in the convertible securities markets today, it may become more prevalent.  One convertible security with loss absorption characteristics is the contingent convertible security (sometimes referred to as a “CoCo”).  These securities provide for mandatory conversion into common stock of the issuer under certain circumstances.  The mandatory conversion might be automatically triggered for instance, if a company fails to meet the capital minimum described in the security, the company’s regulator makes a determination that the security should convert, or the company receives specified levels of extraordinary public support.  Since the common stock of the issuer may not pay a dividend, investors in these instruments could experience a reduced income rate, potentially to zero; and conversion would deepen the subordination of the investor, hence worsening standing in a bankruptcy.  In addition, some such instruments have a set stock conversion rate that would cause an automatic write-down of capital if the price of the stock is below the conversion price on the conversion date.  In another version of a security with loss absorption characteristics, the liquidation value of the security may be adjusted downward to below the original par value under certain circumstances similar to those which would trigger a CoCo.  The write down of the par value would occur automatically and would not entitle the holders to seek bankruptcy of the company.  In certain versions of the instruments, the notes will write down to zero under certain circumstances and investors could lose everything even as the issuer remains in business.

Synthetic convertible securities may include either cash-settled convertibles or manufactured convertibles.  Cash-settled convertibles are instruments that are created by the issuer and have the economic characteristics of traditional convertible securities but may not actually permit conversion into the underlying equity securities in all circumstances. As an example, a private company may issue a cash-settled convertible that is convertible into common stock only if the company successfully completes a public offering of its common stock prior to maturity and otherwise pays a cash amount to reflect any equity appreciation. Manufactured convertibles are created by the investment adviser or another party by combining separate securities that possess one of the two principal characteristics of a convertible security, i.e. , fixed-income (“fixed-income component”) or a right to acquire equity securities (“convertibility component”). The fixed-income component is achieved by investing in nonconvertible fixed-income securities, such as nonconvertible bonds, preferred securities and money market instruments. The convertibility component is achieved by investing in call options, warrants, or other securities with equity conversion features (“equity features”) granting the holder the right to purchase a specified quantity of the underlying stocks within a specified period of time at a specified price or, in the case of a stock index option, the right to receive a cash payment based on the value of the underlying stock index. A manufactured convertible differs from traditional convertible securities in several respects. Unlike a traditional convertible security, which is a single security that has a unitary market value, a manufactured convertible is comprised of two or more separate securities, each with its own market value. Therefore, the total “market value” of such a manufactured convertible is the sum of the values of its fixed-income component and its convertibility component. More flexibility is possible in the creation of a manufactured convertible than in the purchase of a traditional convertible security. Because many corporations have not issued convertible securities, the investment adviser may combine a fixed-income instrument and an equity feature with respect to the stock of the issuer of the fixed-income instrument to create a synthetic convertible security otherwise unavailable in the market. The investment adviser may also combine a fixed-income instrument of an issuer with an equity feature with respect to the stock of a different issuer when the investment adviser believes such a manufactured convertible would better promote the Fund’s objective than alternative investments. For example, the investment adviser may combine an equity feature with respect to an issuer’s stock with a fixed-income security of a different issuer in the same industry to diversify the Fund’s credit exposure, or with a U.S. Treasury instrument to create a manufactured convertible with a higher credit profile than a traditional convertible security issued by that issuer. A manufactured convertible also is a more flexible investment in that its two components may be purchased separately and, upon purchasing the separate securities, “combined” to create a manufactured convertible. For example, the Fund may purchase a warrant for eventual inclusion in a manufactured convertible while postponing the purchase of a suitable bond to pair with the warrant pending development of more favorable market conditions.  The value of a manufactured convertible may respond to certain market fluctuations differently from a traditional convertible security with similar characteristics. For example, in the event the Fund created a manufactured convertible by combining a short-term U.S. Treasury instrument and a call option on a stock, the manufactured convertible would be expected to outperform a traditional convertible of similar maturity that is convertible into that stock during periods when Treasury instruments outperform corporate fixed-income securities and underperform during periods when corporate fixed-income securities outperform Treasury instruments.

Credit Linked Securities

See also “Derivative Instruments and Related Risks” herein.  Credit linked securities are issued by a limited purpose trust or other vehicle that, in turn, invests in a derivative instrument or basket of derivative instruments, such as credit default swaps, interest rate swaps, and other securities in order to provide exposure to certain fixed-income markets. Credit linked securities may be used as a cash management tool in order to gain exposure to a certain market and to remain fully invested when more traditional income producing securities are not available.  Like an investment in a bond, investments in credit linked securities represent the right to receive periodic income payments (in the form of distributions) and payment of principal at the end of the term of the security. However, these payments are conditioned on the issuer’s receipt of payments from, and the issuer’s potential obligations to, the counterparties to the derivative instruments and other securities in which the issuer invests. An issuer may sell one or more credit default swaps, under which the issuer would receive a stream of payments over the term of the swap agreements provided that no event of default has occurred with respect to the referenced debt obligation upon which the swap is based. If a default occurs, the stream of payments may stop and the issuer would be obligated to pay the counterparty the par (or other agreed upon value) of the referenced debt obligation. This, in turn, would reduce the amount of income and principal that the holder of the credit linked security would receive. Credit linked securities generally will be exempt from registration under the 1933 Act. Accordingly, there may be no established trading market for the securities and they may constitute illiquid investments.

Derivative Instruments and Related Risks

Generally, derivatives can be characterized as financial instruments whose performance is derived at least in part from the performance of an underlying reference instrument.  Derivative instruments may be acquired in the United States or abroad and include the various types of exchange-traded and over-the-counter (“OTC”) instruments described herein and other instruments with substantially similar characteristics and risks.  Derivative instruments may be based on securities, indices, currencies, commodities, economic indicators and events (referred to as “reference instruments”).  Fund obligations created pursuant to derivative instruments may be subject to the requirements described under “Asset Coverage” herein.

Derivative instruments are subject to a number of risks, including adverse or unexpected movements in the price of the reference instrument, and counterparty, liquidity, tax, correlation and leverage risks.  Use of derivative instruments may cause the realization of higher amounts of short-term capital gains (generally taxed at ordinary income tax rates) than if such instruments had not been used. Success in using derivative instruments to hedge portfolio assets depends on the degree of price correlation between the derivative instruments and the hedged asset.  Imperfect correlation may be caused by several factors, including temporary price disparities among the trading markets for the derivative instrument, the reference instrument and the Fund’s assets.  To the extent that a derivative instrument is intended to hedge against an event that does not occur, the Fund may realize losses.

OTC derivative instruments involve an additional risk in that the issuer or counterparty may fail to perform its contractual obligations. Some derivative instruments are not readily marketable or may become illiquid under adverse market conditions. In addition, during periods of market volatility, a commodity exchange may suspend or limit trading in an exchange-traded derivative instrument, which may make the contract temporarily illiquid and difficult to price. Commodity exchanges may also establish daily limits on the amount that the price of a futures contract or futures option can vary from the previous day’s settlement price. Once the daily limit is reached, no trades may be made that day at a price beyond the limit. This may prevent the closing out of positions to limit losses.  The staff of the SEC takes the position that certain purchased OTC options, and assets used as cover for written OTC options, are illiquid. The ability to terminate OTC derivative instruments may depend on the cooperation of the counterparties to such contracts. For thinly traded derivative instruments, the only source of price quotations may be the selling dealer or counterparty. In addition, certain provisions of the Code limit the use of derivative instruments.   Derivatives permit the Fund to increase or decrease the level of risk, or change the character of the risk, to which its portfolio is exposed in much the same way as the Fund can increase or decrease the level of risk, or change the character of the risk, of its portfolio by making investments in specific securities.  There can be no assurance that the use of derivative instruments will benefit the Fund.

Direct Investments

Direct investments include (i) the private purchase from an enterprise of an equity interest in the enterprise in the form of shares of common stock or equity interests in trusts, partnerships, joint ventures or similar enterprises, and (ii) the purchase of such an equity interest in an enterprise from a principal investor in the enterprise. At the time of making a direct investment, the Fund will enter into a shareholder or similar agreement with the enterprise and one or more other holders of equity interests in the enterprise. These agreements may, in appropriate circumstances, provide the ability to appoint a representative to the board of directors or similar body of the enterprise and for eventual disposition of the investment in the enterprise. Such a representative would be expected to monitor the investment and protect the Fund’s rights in the investment and would not be appointed for the purpose of exercising management or control of the enterprise.

Diversified Status

With respect to 75% of its total assets, an investment company that is registered with the SEC as a “diversified” fund: (1) may not invest more than 5% of its total assets in the securities of any one issuer (except obligations issued or guaranteed by the U.S. Government, its agencies or instrumentalities and securities of other investment companies); and (2) may not own more than 10% of the outstanding voting securities of any one issuer.

Dividend Capture Trading

In a dividend capture trade, the Fund sells a stock that has gone ex-dividend to purchase another stock paying a dividend before the next dividend of the stock being sold.  The use of a dividend capture trading strategy exposes the Fund to higher portfolio turnover, increased trading costs and potential for capital loss or gain, particularly in the event of significant short-term price movements of stocks subject to dividend capture trading.

Duration

Duration measures the time-weighted expected cash flows of a fixed-income security, which can determine its sensitivity to changes in the general level of interest rates. Securities with longer durations generally tend to be more sensitive to interest rate changes than securities with shorter durations. A mutual fund with a longer dollar-weighted average duration generally can be expected to be more sensitive to interest rate changes than a fund with a shorter dollar-weighted average duration. Duration differs from maturity in that it considers a security’s coupon payments in addition to the amount of time until the security matures. Various techniques may be used to shorten or lengthen Fund duration. As the value of a security changes over time, so will its duration.  The duration of a Fund that invests in multiple Portfolios is the sum of its allocable share of the duration of each of the Portfolios in which it invests, which is determined by multiplying the Portfolio’s duration by the Fund’s percentage ownership of that Portfolio.

Emerging Market Investments

The risks described under “Foreign Investments” herein generally are heightened in connection with investments in emerging markets.  Also, investments in securities of issuers domiciled in countries with emerging capital markets may involve certain additional risks that do not generally apply to investments in securities of issuers in more developed capital markets, such as (i) low or non-existent trading volume, resulting in a lack of liquidity and increased volatility in prices for such securities, as compared to securities of comparable issuers in more developed capital markets; (ii) uncertain national policies and social, political and economic instability, increasing the potential for expropriation of assets, confiscatory taxation, high rates of inflation or unfavorable diplomatic developments; (iii) possible fluctuations in exchange rates, differing legal systems and the existence or possible imposition of exchange controls, custodial restrictions or other foreign or U.S. governmental laws or restrictions applicable to such investments; (iv) national policies that may limit investment opportunities, such as restrictions on investment in issuers or industries deemed sensitive to national interests; and (v) the lack or relatively early development of legal structures governing private and foreign investments and private property. Trading practices in emerging markets also may be less developed, resulting in inefficiencies relative to trading in more developed markets, which may result in increased transaction costs.  

Repatriation of investment income, capital and proceeds of sales by foreign investors may require governmental registration and/or approval in emerging market countries.  There can be no assurance that repatriation of income, gain or initial capital from these countries will occur.  In addition to withholding taxes on investment income, some countries with emerging markets may impose differential capital gains taxes on foreign investors.  

Political and economic structures in emerging market countries may undergo significant evolution and rapid development, and these countries may lack the social, political and economic stability characteristic of more developed countries. In such a dynamic environment, there can be no assurance that any or all of these capital markets will continue to present viable investment opportunities. In the past, governments of such nations have expropriated substantial amounts of private property, and most claims of the property owners have never been fully settled. There is no assurance that such expropriations will not reoccur. In such an event, it is possible that the entire value of an investment in the affected market could be lost. In addition, unanticipated political or social developments may affect the value of investments in these countries and the availability of additional investments. The small size and inexperience of the securities markets in certain of these countries and the limited volume of trading in securities in these countries may make investments in the countries illiquid and more volatile than investments in developed markets.

 Also, there may be less publicly available information about issuers in emerging markets than would be available about issuers in more developed capital markets, and such issuers may not be subject to accounting, auditing and financial reporting standards and requirements comparable to those to which U.S. companies are subject. In certain countries with emerging capital markets, reporting standards vary widely. As a result, traditional investment measurements used in the United States, such as price/earnings ratios, may not be applicable. Certain emerging market securities may be held by a limited number of persons. This may adversely affect the timing and pricing of the acquisition or disposal of securities.  The prices at which investments may be acquired may be affected by trading by persons with material non-public information and by securities transactions by brokers in anticipation of transactions in particular securities.

Practices in relation to settlement of securities transactions in emerging markets involve higher risks than those in developed markets, in part because brokers and counterparties in such markets may be less well capitalized, and custody and registration of assets in some countries may be unreliable. The possibility of fraud, negligence, undue influence being exerted by the issuer or refusal to recognize ownership exists in some emerging markets.  As an alternative to investing directly in emerging markets, exposure may be obtained through derivative investments.

Equity Investments

Equity investments include common and preferred stocks (see “Preferred Securities”); depositary receipts; equity interests in trusts, partnerships, joint ventures and other unincorporated entities or enterprises; convertible preferred securities and other convertible debt instruments; and warrants.

Equity Linked Securities

See also “Derivative Instruments and Related Risks” herein.  Equity linked securities are privately issued securities whose investment results are designed to correspond generally to the performance of a specified stock index or “basket” of securities, or sometimes a single stock.  These securities are used for many of the same purposes as derivative instruments and share many of the same risks.  Equity linked securities may be considered illiquid and thus subject to the Fund’s restrictions on investments in illiquid securities.

Events Regarding FNMA and FHLMC

The value of FNMA and FHLMC securities fell sharply in 2008 due to concerns that these agencies did not have sufficient capital to offset losses. In mid-2008, the U.S. Treasury Department was authorized to increase the size of home loans that FNMA and FHLMC could purchase in certain residential areas and, until 2009, to lend FNMA and FHLMC emergency funds and to purchase the companies’ stock. In September 2008, the U.S. Treasury Department announced that FNMA and FHLMC had been placed in conservatorship by the Federal Housing Finance Agency (“FHFA”), a newly created independent regulator. In connection with the conservatorship, the U.S. Treasury Department entered into Senior Preferred Stock Purchase Agreements (“PSPAs”) under which, if the FHFA determines that the liabilities of FNMA and FHLMC have exceeded their assets under generally accepted accounting principles, the U.S. Treasury Department will contribute cash capital to the company in an amount equal to the difference between liabilities and assets. The PSPAs are designed to provide protection to the senior and subordinated debt and the MBS issued by FNMA and FHLMC. On February 18, 2009, the U.S. Treasury Department announced that it was doubling the size of its commitment to each of FNMA and FHLMC under the Senior Preferred Stock Program to $200 billion.  The U.S. Treasury Department’s obligations under the Senior Preferred Stock Program are for an indefinite period of time for a maximum amount of $200 billion per entity.  FNMA and FHLMC are continuing to operate as going concerns while in conservatorship, and each remains liable for all of its obligations, including its guaranty obligations, associated with its mortgage-backed securities.  The Senior Preferred Stock Purchase Agreement is intended to enhance each of FNMA and FHLMC’s ability to meet its obligations.  FHFA has indicated that the conservatorship of each entity will end when the director of FHFA determines that FHFA’s plan to restore the entity to a safe and solvent condition has been completed.  No assurance can be given that the U.S. Treasury Department initiatives discussed above with respect to the debt and mortgage-backed securities issued by FNMA and FHLMC will be successful.

Exchange-Traded Funds (“ETFs”)

ETFs are pooled investment vehicles that are designed to provide investment results corresponding to an index. These indexes may be either broad-based, sector or international.  ETFs usually are units of beneficial interest in an investment trust or represent undivided ownership interests in a portfolio of securities (or commodities), in each case with respect to a portfolio of all or substantially all of the component securities of, and in substantially the same weighting as, the relevant benchmark index.  ETFs are designed to provide investment results that generally correspond to the price and yield performance of the component securities (or commodities) of the benchmark index. ETFs are listed on an exchange and trade in the secondary market on a per-share basis.   The values of ETFs are subject to change as the values of their respective component securities (or commodities) fluctuate according to market volatility.  Investments in ETFs may not exactly match the performance of a direct investment in the respective indices to which they are intended to correspond due to the temporary unavailability of certain index securities in the secondary market or other extraordinary circumstances, such as discrepancies with respect to the weighting of securities.  Typically, the ETF bears its own operational expenses, which are deducted from its assets. To the extent that the Fund invests in ETFs, the Fund must bear these expenses in addition to the expenses of its own operation.

Exchange-Traded Notes (“ETNs”)

ETNs are senior, unsecured, unsubordinated debt securities whose returns are linked to the performance of a particular market benchmark or strategy minus applicable fees. ETNs are traded on an exchange during normal trading hours. However, investors can also hold the ETN until maturity. At maturity, the issuer pays to the investor a cash amount equal to the principal amount, subject to the day’s market benchmark or strategy factor.

ETNs do not make periodic coupon payments or provide principal protection. ETNs are subject to credit risk and the value of the ETN may drop due to a downgrade in the issuer’s credit rating, despite the underlying market benchmark or strategy remaining unchanged. The value of an ETN may also be influenced by time to maturity, level of supply and demand for the ETN, volatility and lack of liquidity in underlying assets, changes in the applicable interest rates, changes in the issuer’s credit rating, and economic, legal, political, or geographic events that affect the referenced underlying asset. When the Fund invests in ETNs it will bear its proportionate share of any fees and expenses borne by the ETN. The Fund’s decision to sell its ETN holdings may be limited by the availability of a secondary market. In addition, although an ETN may be listed on an exchange, the issuer may not be required to maintain the listing and there can be no assurance that a secondary market will exist for an ETN.

ETNs are subject to tax risk. No assurance can be given that the IRS will accept, or a court will uphold, how the Fund characterizes and treats ETNs for tax purposes. Further, the IRS and Congress are considering proposals that would change the timing and character of income and gains from ETNs.

An ETN that is tied to a specific market benchmark or strategy may not be able to replicate and maintain exactly the composition and relative weighting of securities, commodities or other components in the applicable market benchmark or strategy. Some ETNs that use leverage can, at times, be relatively illiquid and, thus, they may be difficult to purchase or sell at a fair price. Leveraged ETNs are subject to the same risk as other instruments that use leverage in any form.

The market value of ETN shares may differ from that of their market benchmark or strategy. This difference in price may be due to the fact that the supply and demand in the market for ETN shares at any point in time is not always identical to the supply and demand in the market for the securities, commodities or other components underlying the market benchmark or strategy that the ETN seeks to track. As a result, there may be times when an ETN share trades at a premium or discount to its market benchmark or strategy.

Fixed-Income Securities

Fixed-income securities are used by issuers to borrow money. Fixed-income securities include bonds, preferred, preference and convertible securities, notes, debentures, asset-backed securities (including those backed by mortgages), loan participations and assignments, equipment lease certificates, equipment trust certificates and conditional sales contracts. Generally, issuers of fixed-income securities pay investors periodic interest and repay the amount borrowed either periodically during the life of the security and/or at maturity.  Some fixed-income securities, such as zero coupon bonds, do not pay current interest, but are purchased at a discount from their face values, and values accumulate over time to face value at maturity.  The market prices of fixed-income securities fluctuate depending on such factors as interest rates, credit quality and maturity.  In general, market prices of fixed-income securities decline when interest rates rise and increase when interest rates fall. Fixed-income securities are subject to risk factors such as sensitivity to interest rate and real or perceived changes in economic conditions, payment expectations, liquidity and valuation.  Fixed-income securities with longer maturities (for example, over ten years) are more affected by changes in interest rates and provide less price stability than securities with short-term maturities (for example, one to ten years). Fixed-income securities bear the risk of principal and interest default by the issuer, which will be greater with higher yielding, lower grade securities. During an economic downturn, the ability of issuers to service their debt may be impaired.  The rating assigned to a fixed-income security by a rating agency does not reflect assessment of the volatility of the security’s market value or of the liquidity of an investment in the securities. Credit ratings are based largely on the issuer’s historical financial condition and a rating agency’s investment analysis at the time of rating, and the rating assigned to any particular security is not necessarily a reflection of the issuer’s current financial condition. Credit quality can change from time to time, and recently issued credit ratings may not fully reflect the actual risks posed by a particular high yield security. If relevant to the Fund(s) in this SAI, corporate bond ratings are described in an appendix to the SAI (see the table of contents).  While typically paying a fixed rate of income, preferred securities may be considered to be equity securities for purposes of the Fund’s investment restrictions.

Foreign Currency Transactions

As measured in U.S. dollars, the value of assets denominated in foreign currencies may be affected favorably or unfavorably by changes in foreign currency rates and exchange control regulations. Currency exchange rates can also be affected unpredictably by intervention by U.S. or foreign governments or central banks, or the failure to intervene, or by currency controls or political developments in the United States or abroad. Foreign currency exchange transactions may be conducted on a spot ( i.e. , cash) basis at the spot rate prevailing in the foreign currency exchange market or through entering into derivative currency transactions (see “Forward Foreign Currency Exchange Contracts,” “Option Contracts,” “Futures Contracts” and “Swap Agreements – Currency Swaps” herein).  Currency transactions are subject to the risk of a number of complex political and economic factors applicable to the countries issuing the underlying currencies. Furthermore, unlike trading in most other types of instruments, there is no systematic reporting of last sale information with respect to the foreign currencies underlying the derivative currency transactions. As a result, available information may not be complete. In an over-the-counter trading environment, there are no daily price fluctuation limits.

Foreign Investments

Investing in securities issued by companies whose principal business activities are outside the United States may involve significant risks not present in domestic investments. For example, because foreign companies may not be subject to uniform accounting, auditing and financial reporting standards, practices and requirements and regulatory measures comparable to those applicable to U.S. companies, there may be less publicly available information about a foreign company than about a domestic company. Volume and liquidity in most foreign debt markets is less than in the United States and securities of some foreign companies are less liquid and more volatile than securities of comparable U.S. companies. There is generally less government supervision and regulation of securities exchanges, broker-dealers and listed companies than in the United States. In addition, with respect to certain foreign countries, there is the possibility of nationalization, expropriation or confiscatory taxation, currency blockage, political or social instability, or diplomatic developments, which could affect investments in those countries. Any of these actions could adversely affect securities prices, impair the Fund’s ability to purchase or sell foreign securities, or transfer the Fund’s assets or income back to the United States, or otherwise adversely affect Fund operations.  In the event of nationalization, expropriation or confiscation, the Fund could lose its entire investment in that country.  

Other potential foreign market risks include exchange controls, difficulties in valuing securities, defaults on foreign government securities, and difficulties of enforcing favorable legal judgments in foreign courts.  Moreover, individual foreign economies may differ favorably or unfavorably from the U.S. economy in such respects as growth of gross national product, reinvestment of capital, rate of inflation, capital reinvestment, resource self-sufficiency, and balance of payments position. Certain economies may rely heavily on particular industries or foreign capital and are more vulnerable to diplomatic developments, the imposition of economic sanctions against a particular country or countries, changes in international trading patterns, trade barriers, and other protectionist or retaliatory measures.  Foreign securities markets, while growing in volume and sophistication, are generally not as developed as those in the United States.  Foreign countries may not have the infrastructure or resources to respond to natural and other disasters that interfere with economic activities, which may adversely affect issuers located in such countries.

Settlement and clearance procedures in certain foreign markets differ significantly from those in the United States. Payment for securities before delivery may be required and in some countries delayed settlements are customary, which increases the Fund’s risk of loss. The Fund generally holds its foreign securities and related cash in foreign banks and securities depositories. Some foreign banks and securities depositories may be recently organized or new to the foreign custody business. In addition, there may be limited or no regulatory oversight over their operations. Also, the laws of certain countries may put limits on the Fund’s ability to recover its assets if a foreign bank, depository or issuer of a security or any of their agents goes bankrupt.  Certain countries may require withholding on dividends paid on portfolio securities and on realized capital gains.

In addition, it is often more expensive to buy, sell and hold securities in certain foreign markets than in the United States. Foreign brokerage commissions are generally higher than commissions on securities traded in the United States and may be non-negotiable.  The fees paid to foreign banks and securities depositories generally are higher than those charged by U.S. banks and depositories.  The increased expense of investing in foreign markets reduces the amount earned on investments and typically results in a higher operating expense ratio for the Fund as compared to investment companies that invest only in the United States.

Depositary receipts (including American Depositary Receipts (“ADRs”) and Global Depositary Receipts “GDRs”)) are certificates evidencing ownership of shares of a foreign issuer and are alternatives to directly purchasing the underlying foreign securities in their national markets and currencies. However, they continue to be subject to many of the risks associated with investing directly in foreign securities. These risks include the political and economic risks of the underlying issuer’s country, as well as in the case of depositary receipts traded on foreign markets, exchange risk.  Depositary receipts may be sponsored or unsponsored. Unsponsored depositary receipts are established without the participation of the issuer. As a result, available information concerning the issuer of an unsponsored depository receipt may not be as current as for sponsored depositary receipts, and the prices of unsponsored depositary receipts may be more volatile than if such instruments were sponsored by the issuer. Unsponsored depositary receipts may involve higher expenses, may not pass through voting or other shareholder rights and they may be less liquid.

Unless otherwise provided in the Prospectus, in determining the domicile of an issuer, the investment adviser may consider the domicile determination of the Fund’s benchmark index or a leading provider of global indexes and may take into account such factors as where the company’s securities are listed, and where the company is legally organized, maintains principal corporate offices and/or conducts its principal operations.

Forward Foreign Currency Exchange Contracts

See also “Derivative Instruments and Related Risks” herein.  A forward foreign currency exchange contract involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts may be bought or sold to protect against an adverse change in the relationship between currencies or to increase exposure to a particular foreign currency. Cross-hedging may be done by using forward contracts in one currency (or basket of currencies) to hedge against fluctuations in the value of instruments denominated in a different currency (or the basket of currencies and the underlying currency). Use of a different foreign currency (for hedging or non-hedging purposes) magnifies exposure to foreign currency exchange rate fluctuations. Forward foreign currency exchange contracts are individually negotiated and privately traded so they are dependent upon the creditworthiness of the counterparty. The precise matching of the forward contract amounts and the value of the instruments denominated in the corresponding currencies will not generally be possible. In addition, it may not be possible to hedge against long-term currency changes.

When a currency is difficult to hedge or to hedge against the U.S. dollar, the Fund may enter into a forward contract to sell a currency whose changes in value are generally considered to be linked to such currency. Currency transactions can result in losses if the currency being hedged fluctuates in value to a degree or in a direction that is not anticipated. In addition, there is the risk that the perceived linkage between various currencies may not be present or may not be present during the particular time the hedge is in place. If the Fund purchases a bond denominated in a foreign currency with a higher interest rate than is available on U.S. bonds of a similar maturity, the additional yield on the foreign bond could be substantially reduced or lost if the Fund were to enter into a direct hedge by selling the foreign currency and purchasing the U.S. dollar.  

Some of the forward foreign currency exchange contracts may be classified as non-deliverable forwards ("NDFs"). NDFs are cash-settled, forward contracts that may be thinly traded. NDFs are commonly quoted for time periods of one month up to two years, and are normally quoted and settled in U.S. dollars, but may be settled in other currencies. They are often used to gain exposure to or hedge exposure to foreign currencies that are not internationally traded.  NDFs may also be used to gain or hedge exposure to gold.

Forward Rate Agreements

See also “Derivative Instruments and Related Risks” herein.  Under a forward rate agreement, the buyer locks in an interest rate at a future settlement date. If the interest rate on the settlement date exceeds the lock rate, the buyer pays the seller the difference between the two rates. If the lock rate exceeds the interest rate on the settlement date, the seller pays the buyer the difference between the two rates. Any such gain received by the Fund would be taxable.  These instruments are traded in the OTC market.

Fund Investing in a Portfolio

The Board may discontinue the Fund’s investment in one or more Portfolios if it determines that it is in the best interest of the Fund and its shareholders to do so. In such an event, the Board would consider what action might be taken, including investing Fund assets in another pooled investment entity or retaining an investment adviser to manage Fund assets in accordance with its investment objective(s). The Fund’s investment performance and expense ratio may be affected if its investment structure is changed or if another Portfolio investor withdraws all or a portion of its investment in the Portfolio.

Futures Contracts

See also “Derivative Instruments and Related Risks” herein.  Futures contracts are standardized contracts that obligate a purchaser to take delivery, and a seller to make delivery, of a specific amount of the underlying reference instrument at a specified future date at a specified price.  These contracts are traded on exchanges, so that, in most cases, either party can close out its position on the exchange for cash, without delivering the underlying asset.  Upon purchasing or selling a futures contract, a purchaser or seller is required to deposit collateral (initial margin).  Each day thereafter until the futures position is closed, the purchaser or seller will pay additional margin (variation margin) representing any loss experienced as a result of the futures position the prior day or be entitled to a payment representing any profit experienced as a result of the futures position the prior day.  A public market exists in futures contracts covering a number of indexes as well as financial instruments and foreign currencies. It is expected that other futures contracts will be developed and traded in the future.  In computing daily net asset value, the Fund will mark to market its open futures positions. The Fund is also required to deposit and maintain margin with respect to put and call options on futures contracts written by it. Futures contracts are traded on exchanges or boards of trade that are licensed by the CFTC and must be executed through a futures commission merchant or brokerage firm that is a member of the relevant exchange or board.

Although some futures contracts call for making or taking delivery of the underlying reference instrument, 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). Closing a futures contract sale is effected by purchasing a futures contract for the same aggregate amount of the specific type of financial instrument or commodity with the same delivery date. If an offsetting purchase price is less than the original sale price, the Fund realizes a capital gain, or if it is more, the Fund realizes a capital loss. Conversely, if an offsetting sale price is more than the original purchase price, the Fund realizes a capital gain, or if it is less, the Fund realizes a capital loss.

Global Natural Resources Companies

To the extent described in the Prospectus, the Fund may concentrate its investments in global natural resources companies.

Health Sciences Companies

To the extent described in the Prospectus, the Fund may concentrate its investments in health sciences companies.

High Yield Securities

High yield securities (commonly referred to as “junk bonds”) are considered to be of below investment grade quality and generally provide greater income potential and/or increased opportunity for capital appreciation than investments in higher quality debt securities but they also typically entail greater potential price volatility and principal and income risk.  High yield securities may be subject to higher risk and include certain corporate debt obligations, higher yielding preferred securities and mortgage-related securities, and securities convertible into the foregoing.  They are regarded as predominantly speculative with respect to the entity’s continuing ability to meet principal and interest payments.  Also, their yields and market values may fluctuate more than higher rated securities.  Fluctuations in value do not affect the cash income from the securities, but are reflected in the Fund’s net asset value.  The greater risks and fluctuations in yield and value occur, in part, because investors generally perceive issuers of lower rated and unrated securities to be less creditworthy. The secondary market on which high yield securities are traded may be less liquid than the market for higher grade securities.

Hybrid Instruments

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

The risks of investing in hybrid instruments reflect a combination of the risks of investing in securities, options, futures and currencies. An investment in a hybrid instrument may entail significant risks that are not associated with a similar investment in a traditional debt instrument that has a fixed principal amount, is denominated in U.S. dollars or bears interest either at a fixed rate or a floating rate determined by reference to a common, nationally published benchmark. The risks of a particular hybrid instrument will depend upon the terms of the instrument, but may include the possibility of significant changes in the benchmark(s) or the prices of the underlying assets to which the instrument is linked. Such risks generally depend upon factors unrelated to the operations or credit quality of the issuer of the hybrid instrument, which may not be foreseen by the purchaser, such as economic and political events, the supply and demand of the underlying assets and interest rate movements. Hybrid instruments may be highly volatile and their use by the Fund may not be successful.  Hybrid instruments may also carry liquidity risk since the instruments are often “customized” to meet the portfolio needs of a particular investor, and therefore, the number of investors that are willing and able to buy such instruments in the secondary market may be smaller than that for more traditional debt securities.  

Hybrid instruments may bear interest or pay preferred dividends at below market (or even relatively nominal) rates. Alternatively, hybrid instruments may bear interest at above market rates but bear an increased risk of principal loss (or gain). The latter scenario may result if “leverage” is used to structure the hybrid instrument. Leverage risk occurs when the hybrid instrument is structured so that a given change in a benchmark or underlying asset is multiplied to produce a greater value change in the hybrid instrument, thereby magnifying the risk of loss as well as the potential for gain.

Hybrid instruments are potentially more volatile and carry greater market risks than traditional debt instruments. Depending on the structure of the particular hybrid instrument, changes in a benchmark may be magnified by the terms of the hybrid instrument and have an even more dramatic and substantial effect upon the value of the hybrid instrument. Also, the prices of the hybrid instrument and the benchmark or underlying asset may not move in the same direction or at the same time.

Hybrids can be used as an efficient means of pursuing a variety of investment goals, including currency hedging, duration management, and increased total return and creating exposure to a particular market or segment of that market. The value of a hybrid or its interest rate may be a multiple of a benchmark and, as a result, may be leveraged and move (up or down) more steeply and rapidly than the benchmark. These benchmarks may be sensitive to economic and political events, such as commodity shortages and currency devaluations, which cannot be readily foreseen by the purchaser of a hybrid. Under certain conditions, the redemption value of a hybrid could be zero. The purchase of hybrids also exposes the Fund to the credit risk of the issuer of the hybrids. These risks may cause significant fluctuations in the net asset value of the Fund.

Certain hybrid instruments may provide exposure to the commodities markets. These are derivative securities with one or more commodity-linked components that have payment features similar to commodity futures contracts, commodity options, or similar instruments. Commodity-linked hybrid instruments may be either equity or debt securities, leveraged or unleveraged, and are considered hybrid instruments because they have both security and commodity-like characteristics. A portion of the value of these instruments may be derived from the value of a commodity, futures contract, index or other economic variable. The Fund will invest only in commodity-linked hybrid instruments that qualify under applicable rules of the CFTC for an exemption from the provisions of the CEA.  Certain issuers of structured products such as hybrid instruments may be deemed to be investment companies as defined in the 1940 Act. As a result, the Fund’s investments in these products may be subject to limits applicable to investments in investment companies and may be subject to restrictions contained in the 1940 Act.

Illiquid Securities

Illiquid securities include securities legally restricted as to resale, and may include commercial paper issued pursuant to Section 4(2) of the 1933 Act and securities eligible for resale pursuant to Rule 144A thereunder. Section 4(2) and Rule 144A securities may, however, be treated as liquid by the investment adviser pursuant to procedures adopted by the Board, which require consideration of factors such as trading activity, availability of market quotations and number of dealers willing to purchase the security. Even if determined to be liquid, Rule 144A securities may increase the level of portfolio illiquidity if eligible buyers become uninterested in purchasing such securities.

It may be difficult to sell illiquid securities at a price representing fair value until such time as the securities may be sold publicly. It also may be more difficult to determine the fair value of such securities for purposes of computing the Fund’s net asset value.  Where registration is required, a considerable period of time may elapse between a decision to sell the securities and the time when it would be permitted to sell. Thus, the Fund may not be able to obtain as favorable a price as that prevailing at the time of the decision to sell. The Fund may incur additional expense when disposing of illiquid securities, including all or a portion of the cost to register the securities.  The Fund also may acquire securities through private placements under which it may agree to contractual restrictions on the resale of such securities that are in addition to applicable legal restrictions. Such restrictions might prevent the sale of such securities at a time when such sale would otherwise be desirable.

At times, a portion of the Fund’s assets may be invested in securities as to which the Fund, by itself or together with other accounts managed by the investment adviser and its affiliates, holds a major portion or all of such securities. Under adverse market or economic conditions or in the event of adverse changes in the financial condition of the issuer, the Fund could find it more difficult to sell such securities when the investment adviser believes it advisable to do so or may be able to sell such securities only at prices lower than if such securities were more widely held.  It may also be more difficult to determine the fair value of such securities for purposes of computing the Fund’s net asset value.

Indexed Securities

See also “Derivative Instruments and Related Risks” herein.  Indexed securities are securities that fluctuate in value with an index. The interest rate or, in some cases, the principal payable at the maturity of an indexed security may change positively or inversely in relation to one or more interest rates, financial indices, securities prices or other financial indicators (“reference prices”). An indexed security may be leveraged to the extent that the magnitude of any change in the interest rate or principal payable on an indexed security is a multiple of the change in the reference price. Thus, indexed securities may decline in value due to adverse market changes in reference prices. Because indexed securities derive their value from another instrument, security or index, they are considered derivative debt securities, and are subject to different combinations of prepayment, extension, interest rate and/or other market risks. Indexed securities may include interest only (“IO”) and principal only (“PO”) securities, floating rate securities linked to the Cost of Funds Index (“COFI floaters”), other “lagging rate” floating securities, floating rate securities that are subject to a maximum interest rate (“capped floaters”), leveraged floating rate securities (“super floaters”), leveraged inverse floating rate securities (“inverse floaters”), dual index floaters, range floaters, index amortizing notes and various currency indexed notes.  Indexed securities may be issued by the U.S. Government or one of its agencies or instrumentalities or, if privately issued, collateralized by mortgages that are insured, guaranteed or otherwise backed by the U.S. Government, its agencies or instrumentalities.

Inflation-Indexed (or Inflation-Linked) Bonds

Inflation-indexed bonds are fixed-income securities the principal value of which is periodically adjusted according to the rate of inflation. Inflation-indexed bonds are issued by governments, their agencies or instrumentalities and corporations. Two structures are common: The U.S. Treasury and some other issuers use a structure that accrues inflation into the principal value of the bond. Most other issuers pay out the inflation accruals as part of a semiannual coupon.  The principal amount of an inflation-indexed bond is adjusted in response to changes in the level of inflation.  Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds, and therefore, the principal amount of such bonds cannot be reduced below par even during a period of deflation.  However, the current market value of these bonds is not guaranteed and will fluctuate, reflecting the risk of changes in their yields.  In certain jurisdictions outside the United States, the repayment of the original bond principal upon the maturity of an inflation-indexed bond is not guaranteed, allowing for the amount of the bond repaid at maturity to be less than par.  The interest rate for inflation-indexed bonds is fixed at issuance as a percentage of this adjustable principal.  Accordingly, the actual interest income may both rise and fall as the principal amount of the bonds adjusts in response to movements in the Consumer Price Index.  

The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates in turn are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if inflation were to rise at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed bonds. In contrast, if nominal interest rates increased at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed bonds. While these securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. If interest rates rise due to reasons other than inflation (for example, due to changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond’s inflation measure.

Investments in the Subsidiary

The Subsidiary is organized under the laws of the Cayman Islands, and is overseen by a sole director affiliated with Eaton Vance. The Fund is the sole shareholder of the Subsidiary, and it is not currently expected that shares of the Subsidiary will be sold or offered to other investors. The Subsidiary expects to invest primarily in commodity-linked derivative instruments, including swap agreements, commodity options, futures and options on futures, backed by a portfolio of inflation-indexed securities and other fixed-income securities and is also permitted to invest in any other investments permitted by the Fund. To the extent that the Fund invests in the Subsidiary, the Fund will be subject to the risks associated with those derivative instruments and other securities, which are discussed elsewhere in the Prospectus and this SAI.

While the Subsidiary may be operated similarly to the Fund, it is not registered under the 1940 Act and, unless otherwise noted in the Prospectus and this SAI, is not subject to the investor protections of the 1940 Act and other U.S. regulations. Changes in the laws of the U.S. and/or the Cayman Islands could result in the inability of the Fund and/or the Subsidiary to operate as described in the Prospectus and this SAI and could negatively affect the Fund and its shareholders.

Junior Loans

Due to their lower place in the borrower’s capital structure and possible unsecured status, certain loans (“Junior Loans”) involve a higher degree of overall risk than Senior Loans (described below) of the same borrower.  Junior Loans, which may be direct loans or purchased either in the form of an assignment or a loan participation.  Junior Loans are subject to the same general risks inherent in any loan investment (see “Loans” below). Junior Loans include secured and unsecured subordinated loans, as well as second lien loans and subordinated bridge loans. A second lien loan is generally second in line in terms of repayment priority and may have a claim on the same collateral pool as the first lien or it may be secured by a separate set of assets. Second lien loans generally give investors priority over general unsecured creditors in the event of an asset sale.

Bridge loans or bridge facilities are short-term loan arrangements (e.g., 12 to 18 months) typically made by a borrower in anticipation of intermediate-term or long-term permanent financing. Most bridge loans are structured as floating-rate debt with step-up provisions under which the interest rate on the bridge loan rises the longer the loan remains outstanding and may be converted into senior exchange notes if the loan has not been prepaid in full on or prior to its maturity date. Bridge loans may be subordinate to other debt and may be secured or unsecured. Bridge loans are generally made with the expectation that the borrower will be able to obtain permanent financing in the near future. Any delay in obtaining permanent financing subjects the bridge loan investor to increased risk. A borrower with an outstanding bridge loan may be unable to locate permanent financing to replace the bridge loan, which may impair the borrower’s perceived creditworthiness. From time to time, the Fund may make a commitment to participate in a bridge loan facility, obligating itself to participate in the facility if it funds. In return for this commitment, the Fund receives a fee.

For additional disclosure relating to investing in loans (including Junior Loans), see “Loans” below.  

Liquidity or Protective Put Agreements

See also “Derivative Instruments and Related Risks” herein.  The Fund may enter into a separate agreement with the seller of an instrument or some other person granting the Fund the right to put the instrument to the seller thereof or the other person at an agreed upon price.  Interest income generated by certain municipal bonds with put or demand features may be taxable.

Loan Facility

Senior Debt Portfolio may employ borrowings and leverage as described in the Prospectus. The Portfolio has entered into a commercial paper program and liquidity facility subject to the terms of an Order of the SEC (Release No. 26320) granting an exemption from Section 18(f)(1) of the 1940 Act. The program, administered by Citicorp North America, Inc., is with certain conduit lenders who issue commercial paper, in an amount up to $640 million through which the Portfolio employs leverage pursuant to its investment guidelines and subject to the risks described in the Prospectus. Under the terms of the program, the Portfolio pays an annual fee equal to 0.65% on its outstanding borrowings for the administration of the program and an annual fee of either 0.35% or 0.45% on the total commitment amount depending on the amount of outstanding borrowings, as well as interest on advances under the program.

Loans

Loans may be primary, direct investments or investments in loan assignments or participation interests.  A loan assignment represents a portion or the entirety of a loan and a portion of the entirety of a position previously attributable to a different lender. The purchaser of an assignment typically succeeds to all the rights and obligations under the loan agreement and has the same rights and obligations as the assigning investor.  However, assignments through private negotiations may cause the purchaser of an assignment to have different and more limited rights than those held by the assigning investor.  Loan participation interests are interests issued by a lender or other entity and represent a fractional interest in a loan. The Fund typically will have a contractual relationship only with the financial institution that issued the participation interest. As a result, the Fund may have the right to receive payments of principal, interest and any fees to which it is entitled only from the financial institution and only upon receipt by such entity of such payments from the borrower. In connection with purchasing a participation interest, the Fund generally will have no right to enforce compliance by the borrower with the terms of the loan agreement, nor any rights with respect to any funds acquired by other investors through set-off against the borrower and the Fund may not directly benefit from the collateral supporting the loan in which it has purchased the participation interest. As a result, the Fund may assume the credit risk of both the borrower and the financial institution issuing the participation interest. In the event of the insolvency of the entity issuing a participation interest, the Fund may be treated as a general creditor of such entity.

Loans may be originated by a lending agent, such as a financial institution or other entity, on behalf of a group or “syndicate” of loan investors (the “Loan Investors”).  In such a case, the agent administers the terms of the loan agreement and is responsible for the collection of principal, and interest payments from the borrower and the apportionment of these payments to the Loan Investors. Failure by the agent to fulfill its obligations may delay or adversely affect receipt of payment by the Fund. Furthermore, unless under the terms of a loan agreement or participation (as applicable) the Fund has direct recourse against the borrower, the Fund must rely on the Agent and the other Loan Investors to use appropriate remedies against the borrower.

Loan investments may be made at par or at a discount or premium to par.  The interest payable on a loan may be fixed or floating rate, and paid in cash or in-kind.  In connection with transactions in loans, the Fund may be subject to facility or other fees.  Loans may be secured by specific collateral or other assets of the borrower, guaranteed by a third party, unsecured or subordinated.  During the term of a loan, the value of any collateral securing the loan may decline in value, causing the loan to be under collateralized. Collateral may consist of assets that may not be readily liquidated, and there is no assurance that the liquidation of such assets would satisfy fully a borrower’s obligations under the loan. In addition, if a loan is foreclosed, the Fund could become part owner of the collateral and would bear the costs and liabilities associated with owning and disposing of such collateral.

A lender’s repayment and other rights primarily are determined by governing loan, assignment or participation documents, which (among other things) typically establish the priority of payment on the loan relative to other indebtedness and obligations of the borrower.  In the event of bankruptcy, applicable law may impact a lender’s ability to enforce its rights under such documents.  Investing in loans involves the risk of default by the borrower or other party obligated to repay the loan.  In the event of insolvency of the borrower or other obligated party, the Fund may be treated as a general creditor of such entity unless it has rights that are senior to that of other creditors or secured by specific collateral or assets of the borrower.  Fixed-rate loans are also subject to the risk that their value will decline in a rising interest rate environment.  This risk is mitigated for floating-rate loans, where the interest rate payable on the loan resets periodically by reference to a base lending rate.  The base lending rate usually is the London Interbank Offered Rate ("LIBOR"), the Federal Reserve federal funds rate, the prime rate or other base lending rates used by commercial lenders. LIBOR usually is an average of the interest rates quoted by several designated banks as the rates at which they pay interest to major depositors in the London interbank market on U.S. dollar-denominated deposits.

The Fund will take whatever action it considers appropriate in the event of anticipated financial difficulties, default or bankruptcy of the borrower or other entity obligated to repay a loan. Such action may include: (i) retaining the services of various persons or firms (including affiliates of the investment adviser) to evaluate or protect any collateral or other assets securing the loan or acquired as a result of any such event; (ii) managing (or engaging other persons to manage) or otherwise dealing with any collateral or other assets so acquired; and (iii) taking such other actions (including, but not limited to, payment of operating or similar expenses relating to the collateral) as the investment adviser may deem appropriate to reduce the likelihood or severity of loss on the Fund’s investment and/or maximize the return on such investment.  The Fund will incur additional expenditures in taking protective action with respect to loans in (or anticipated to be in) default and assets securing such loans.  In certain circumstances, the Fund may receive equity or equity-like securities from a borrower to settle the loan or may acquire an equity interest in the borrower.  Representatives of the Fund also may join creditor or similar committees relating to loans.

Lenders can be sued by other creditors and the debtor and its shareholders. Losses could be greater than the original loan amount and occur years after the loan’s recovery. If a borrower becomes involved in bankruptcy proceedings, a court may invalidate the Fund’s security interest in any loan collateral or subordinate the Fund’s rights under the loan agreement to the interests of the borrower’s unsecured creditors or cause interest previously paid to be refunded to the borrower. There are also other events, such as the failure to perfect a security interest due to faulty documentation or faulty official filings, which could lead to the invalidation of the Fund’s security interest in loan collateral. If any of these events occur, the Fund’s performance could be negatively affected.

Interests in loans generally are not listed on any national securities exchange or automated quotation system and no active market may exist for many loans, making them illiquid. As described below, a secondary market exists for many Senior Loans, but it may be subject to irregular trading activity, wide bid/ask spreads and extended trade settlement periods.

From time to time the investment adviser and its affiliates may borrow money from various banks in connection with their business activities. Such banks may also sell interests in loans to or acquire them from the Fund or may be intermediate participants with respect to loans in which the Fund owns interests. Such banks may also act as agents for loans held by the Fund.

To the extent that legislation or state or federal regulators that regulate certain financial institutions impose additional requirements or restrictions with respect to the ability of such institutions to make loans, particularly in connection with highly leveraged transactions, the availability of loans for investment may be adversely affected. Further, such legislation or regulation could depress the market value of loans.

For additional disclosures relating to Junior and Senior Loans, see “Junior Loans” and “Senior Loans” herein.

Master Limited Partnerships ("MLPs")

MLPs are publicly-traded limited partnership interests or units. An MLP that invests in a particular industry (e.g., oil and gas) will be harmed by detrimental economic events within that industry. As partnerships, MLPs may be subject to less regulation (and less protection for investors) under state laws than corporations. In addition, MLPs may be subject to state taxation in certain jurisdictions, which may reduce the amount of income paid by an MLP to its investors.

Mortgage-Backed Securities (“MBS”)

MBS are “pass through” securities, meaning that a pro rata share of regular interest and principal payments, as well as unscheduled early prepayments, on the underlying mortgage pool is passed through monthly to the holder.  MBS may include conventional mortgage pass through securities, participation interests in pools of adjustable and fixed rate mortgage loans, stripped mortgage-backed securities (described herein), floating rate mortgage-backed securities and certain classes of multiple class CMOs. MBS pay principal to the holder over their term, which differs from other forms of debt securities that normally provide for principal payment at maturity or specified call dates. MBS are subject to the general risks associated with investing in real estate securities; that is, they may lose value if the value of the underlying real estate to which a pool of mortgages relates declines.  In addition, investments in MBS involve certain specific risks, including the failure of a party to meet its commitments under the related operative documents, adverse interest rate changes and the effects of prepayments on mortgage cash flows.  Certain MBS may be purchased on a when-issued basis subject to certain limitations and requirements.

There are currently three types of MBS: (1) 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”); (2) 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 (3) 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 that usually have some form of private credit enhancement.  Privately issued MBS are structured similar to GNMA, FNMA and FHLMC MBS, and are issued by originators or and investors in mortgage loans, including depositary institutions mortgage banks and special purpose subsidiaries of the foregoing.

GNMA Certificates and FNMA Mortgage-Backed Certificates are MBS representing part ownership of a pool of mortgage loans. GNMA loans (issued by lenders such as mortgage bankers, commercial banks and savings and loan associations) are either insured by the Federal Housing Administration or guaranteed by the Veterans Administration. A pool of such mortgages is assembled and, after being approved by GNMA, is offered to investors through securities dealers. Once such pool is approved by GNMA, the timely payment of interest and principal on the Certificates issued representing such pool is guaranteed by the full faith and credit of the U.S. Government. GNMA is a wholly owned U.S. Government corporation within the Department of Housing and Urban Development.  FNMA, a federally chartered corporation owned entirely by private stockholders, purchases both conventional and federally insured or guaranteed residential mortgages from various entities, including savings and loan associations, savings banks, commercial banks, credit unions and mortgage bankers, and packages pools of such mortgages in the form of pass-through securities generally called FNMA Mortgage-Backed Certificates, which are guaranteed as to timely payment of principal and interest by FNMA but are not backed by the full faith and credit of the U.S. Government; however, they are supported by the right of FNMA to borrow from the U.S. Treasury Department.

 FHLMC, a corporate instrumentality of the U.S. Government created by Congress for the purposes of increasing the availability of mortgage credit for residential housing, issues participation certificates (“PCs”) representing undivided interest in FHLMC’S mortgage portfolio. While FHLMC guarantees the timely payment of interest and ultimate collection of the principal of its PCs, its PCs are not backed by the full faith and credit of the U.S. Government. FHLMC PCs differ from GNMA Certificates in that the mortgages underlying the PCs are monthly “conventional” mortgages rather than mortgages insured or guaranteed by a federal agency or instrumentality. However, in several other respects, such as the monthly pass-through of interest and principal (including unscheduled prepayments) and the unpredictability of future unscheduled prepayments on the underlying mortgage pools, FHLMC PCs are similar to GNMA Certificates.  See also “Events Regarding FNMA and FHLMC” herein.

While it is not possible to accurately predict the life of a particular issue of MBS, the actual life of any such security is likely to be substantially less than the final maturities of the mortgage loans underlying the security. This is because unscheduled early prepayments of principal on MBS will result from the prepayment, refinancings or foreclosure of the underlying mortgage loans in the mortgage pool. Prepayments of MBS may not be able to be reinvested at the same interest rate.  Because of the regular scheduled payments of principal and the early unscheduled prepayments of principal, MBS is less effective than other types of obligations as a means of “locking-in” attractive long-term interest rates. As a result, this type of security may have less potential for capital appreciation during periods of declining interest rates than other U.S. Government securities of comparable maturities, although many issues of MBS may have a comparable risk of decline in market value during periods of rising interest rates. If MBS is purchased at a premium above its par value, a scheduled payment of principal and an unscheduled prepayment of principal, which would be made at par, will accelerate the realization of a loss equal to that portion of the premium applicable to the payment or prepayment. If MBS has been purchased at a discount from its par value, both a scheduled payment of principal and an unscheduled prepayment of principal will increase current returns and will accelerate the recognition of income, which, when distributed to Fund shareholders, will be taxable as ordinary income.

Mortgage Dollar Rolls

In a mortgage dollar roll, the Fund sells MBS for delivery in the current month and simultaneously contracts to repurchase substantially similar (same type, coupon and maturity) MBS on a specified future date. During the roll period, the Fund forgoes principal and interest paid on the MBS.  The Fund is compensated by the difference between the current sales price and the lower forward price for the future purchase (often referred to as the “drop”) as well as by the interest earned on the cash proceeds of the initial sales. A “covered roll” is a specific type of dollar roll for which there is an offsetting cash position or a cash equivalent security position that matures on or before the forward settlement date of the dollar roll transaction. The Fund will enter into only covered rolls. Covered rolls are not treated as a borrowing or other senior security and will be excluded from the calculation of the Fund’s borrowings and other senior securities.

Municipal Lease Obligations (“MLOs”)

MLOs are obligations in the form of a lease, installment purchase or conditional sales contract (which typically provide for the title to the leased asset to pass to the governmental issuer) that is issued by state or local governments to acquire equipment and facilities. Interest income from MLOs is generally exempt from local and state taxes in the state of issuance.  MLOs, like other municipal debt obligations, are subject to the risk of non-payment. Although MLOs do not constitute general obligations of the issuer for which the issuer’s unlimited taxing power is pledged, a lease obligation is frequently backed by the issuer’s covenant to budget for, appropriate and make the payments due under the lease obligation.  However, certain lease obligations contain “non-appropriation” clauses, which provide that the issuer has no obligation to make lease or installment purchase payments in future years unless money is appropriated for such purpose on a yearly basis. Although “non-appropriation” lease obligations may be secured by the leased property, disposition of the property in the event of foreclosure might prove difficult. Participations in municipal leases are undivided interests in a portion of the total obligation. Participations entitle their holders to receive a pro rata share of all payments under the lease.

MLOs and participations therein represent a type of financing that may not have the depth of marketability associated with more conventional securities and, as such, they may be less liquid than conventional securities.  Certain MLOs may be deemed illiquid for the purpose of the Fund’s limitation on investments in illiquid securities, unless determined by the investment adviser, pursuant to guidelines adopted by the Board, to be liquid securities. The investment adviser will consider a MLO to be liquid if it is rated investment grade (being an MLO rated BBB or Baa or higher) by a nationally recognized statistical ratings organization or is insured by an insurer rated investment grade.  If an MLO or participation does not meet the foregoing criteria, then the investment adviser will consider the MLO to be illiquid unless it conducts an analysis of relevant factors and concludes that the MLO is liquid.  In conducting such an analysis, the investment adviser will consider the factors it believes are relevant to the marketability of the obligation, to the extent that information regarding such factor is available to the investment adviser and pertinent to the liquidity determination, which may include: (1) the willingness of dealers to bid for the obligation; (2) the number of dealers willing to purchase or sell the obligation and the number of other potential buyers; (3) the frequency of trades and quotes for the obligation; (4) the nature of the marketplace trades, including the time needed to dispose of the obligation, the method of soliciting offers, and the mechanics of transfer; (5) the willingness of the governmental issuer to continue to appropriate funds for the payment of the obligation; (6) how likely or remote an event of non-appropriation may be, which depends in varying degrees on a variety of factors, including those relating to the general creditworthiness of the governmental issuer, its dependence on its continuing access to the credit markets, and the importance to the issuer of the equipment, property or facility covered by the lease or contract; (7) an assessment of the likelihood that the lease may or may not be cancelled; and (8) other factors and information unique to the obligation in determining its liquidity.

The ability of issuers of MLOs to make timely lease payments may be adversely impacted in general economic downturns and as relative governmental cost burdens are allocated and reallocated among federal, state and local governmental units. Such non-payment would result in a reduction of income from and value of the obligation. Issuers of MLOs might seek protection under the bankruptcy laws. In the event of bankruptcy of such an issuer, holders of MLOs could experience delays and limitations with respect to the collection of principal and interest on such MLOs and may not, in all circumstances, be able to collect all principal and interest to which it is entitled. To enforce its rights in the event of a default in lease payments, the Fund might take possession of and manage the assets securing the issuer’s obligations on such securities or otherwise incur costs to protect its right, which may increase the Fund’s operating expenses and adversely affect the net asset value of the Fund. When the lease contains a non-appropriation clause, however, the failure to pay would not be a default and the Fund would not have the right to take possession of the assets. Any income derived from the Fund’s ownership or operation of such assets may not be tax-exempt.

Municipal Obligations

Municipal obligations include debt obligations issued to obtain funds for various public purposes, including the construction of a wide range of public facilities, refunding of outstanding obligations and obtaining funds for general operating expenses and loans to other public institutions and facilities.  Certain types of bonds are issued by or on behalf of public authorities to finance various privately owned or operated facilities, including certain facilities for the local furnishing of electric energy or gas, sewage facilities, solid waste disposal facilities and other specialized facilities. Municipal obligations include bonds as well as tax-exempt commercial paper, project notes and municipal notes such as tax, revenue and bond anticipation notes of short maturity, generally less than three years. While most municipal bonds pay a fixed rate of interest semiannually in cash, there are exceptions. Some bonds pay no periodic cash interest, but rather make a single payment at maturity representing both principal and interest. Some bonds may pay interest at a variable or floating rate.  Bonds may be issued or subsequently offered with interest coupons materially greater or less than those then prevailing, with price adjustments reflecting such deviation.  Municipal obligations also include trust certificates representing interests in municipal securities held by a trustee. The trust certificates may evidence ownership of future interest payments, principal payments or both on the underlying securities.

In general, there are three categories of municipal obligations, the interest on which is exempt from federal income tax and is not a tax preference item for purposes of the alternative minimum tax ("AMT"): (i) certain “public purpose” obligations (whenever issued), which include obligations issued directly by state and local governments or their agencies to fulfill essential governmental functions; (ii) certain obligations issued before August 8, 1986 for the benefit of non-governmental persons or entities; and (iii) certain “private activity bonds” issued after August 7, 1986, which include “qualified Section 501(c)(3) bonds” or refundings of certain obligations included in the second category. Opinions relating to the validity of municipal bonds, exclusion of municipal bond interest from an investor’s gross income for federal income tax purposes and, where applicable, state and local income tax, are rendered by bond counsel to the issuing authorities at the time of issuance.

Interest on certain “private activity bonds” issued after August 7, 1986 is exempt from regular federal income tax, but such interest (including a distribution by the Fund derived from such interest) is treated as a tax preference item that could subject the recipient to or increase the recipient’s liability for the AMT. For corporate shareholders, the Fund’s distributions derived from interest on all municipal obligations (whenever issued) are included in “adjusted current earnings” for purposes of the AMT as applied to corporations (to the extent not already included in alternative minimum taxable income as income attributable to private activity bonds).

The two principal classifications of municipal bonds are “general obligation” and “revenue” bonds. Issuers of general obligation bonds include states, counties, cities, towns and regional districts. The proceeds of these obligations are used to fund a wide range of public projects, including the construction or improvement of schools, highways and roads, water and sewer systems and a variety of other public purposes. The basic security of general obligation bonds is the issuer’s pledge of its faith, credit, and taxing power for the payment of principal and interest. The taxes that can be levied for the payment of debt service may be limited or unlimited as to rate and amount.

Typically, the only security for a limited obligation or revenue bond is the net revenue derived from a particular facility or class of facilities financed thereby or, in some cases, from the proceeds of a special tax or other special revenues. Revenue bonds have been issued to fund a wide variety of revenue-producing public capital projects including: electric, gas, water and sewer systems; highways, bridges and tunnels; port and airport facilities; colleges and universities; hospitals; and convention, recreational, tribal gaming and housing facilities. Although the security behind these bonds varies widely, many lower rated bonds provide additional security in the form of a debt service reserve fund that may also be used to make principal and interest payments on the issuer's obligations. In addition, some revenue obligations (as well as general obligations) are insured by a bond insurance company or backed by a letter of credit issued by a banking institution.  Revenue bonds also include, for example, pollution control, health care and housing bonds, which, although nominally issued by municipal authorities, are generally not secured by the taxing power of the municipality but by the revenues of the authority derived from payments by the private entity that owns or operates the facility financed with the proceeds of the bonds. Obligations of housing finance authorities have a wide range of security features, including reserve funds and insured or subsidized mortgages, as well as the net revenues from housing or other public projects. Many of these bonds do not generally constitute the pledge of the credit of the issuer of such bonds. The credit quality of such revenue bonds is usually directly related to the credit standing of the user of the facility being financed or of an institution which provides a guarantee, letter of credit or other credit enhancement for the bond issue.  The Fund may on occasion acquire revenue bonds that carry warrants or similar rights covering equity securities. Such warrants or rights may be held indefinitely, but if exercised, the Fund anticipates that it would, under normal circumstances, dispose of any equity securities so acquired within a reasonable period of time.  Investing in revenue bonds may involve (without limitation) the following risks.

Hospital bond ratings are often based on feasibility studies that contain projections of expenses, revenues and occupancy levels.   A hospital’s income available to service its debt may be influenced by demand for hospital services, management capabilities, the service area economy, efforts by insurers and government agencies to limit rates and expenses, competition, availability and expense of malpractice insurance, and Medicaid and Medicare funding.

Education-related bonds are comprised of two types: (i) those issued to finance projects for public and private colleges and universities, charter schools and private schools, and (ii) those representing pooled interests in student loans. Bonds issued to supply educational institutions with funding are subject to many risks, including the risks of unanticipated revenue decline, primarily the result of decreasing student enrollment, decreasing state and federal funding, or changes in general economic conditions. Additionally, higher than anticipated costs associated with salaries, utilities, insurance or other general expenses could impair the ability of a borrower to make annual debt service payments. Student loan revenue bonds are generally offered by state (or sub-state) authorities or commissions and are backed by pools of student loans. Underlying student loans may be guaranteed by state guarantee agencies and may be subject to reimbursement by the United States Department of Education through its guaranteed student loan program. Others may be private, uninsured loans made to parents or students that may be supported by reserves or other forms of credit enhancement. Cash flows supporting student loan revenue bonds are impacted by numerous factors, including the rate of student loan defaults, seasoning of the loan portfolio, and student repayment deferral periods of forbearance. Other risks associated with student loan revenue bonds include potential changes in federal legislation regarding student loan revenue bonds, state guarantee agency reimbursement and continued federal interest and other program subsidies currently in effect.

Transportation debt may be issued to finance the construction of airports, toll roads, highways, or other transit facilities. Airport bonds are dependent on the economic conditions of the airport’s service area and may be affected by the business strategies and fortunes of specific airlines. They may also be subject to competition from other airports and modes of transportation. Air traffic generally follows broader economic trends and is also affected by the price and availability of fuel. Toll road bonds are also affected by the cost and availability of fuel as well as toll levels, the presence of competing roads and the general economic health of an area. Fuel costs, transportation taxes and fees, and availability of fuel also affect other transportation-related securities, as do the presence of alternate forms of transportation, such as public transportation.

Industrial development bonds are normally secured only by the revenues from the project and not by state or local government tax payments, they are subject to a wide variety of risks, many of which relate to the nature of the specific project. Generally, IDBs are sensitive to the risk of a slowdown in the economy.

Electric utilities face problems in financing large construction programs in an inflationary period, cost increases and delay occasioned by safety and environmental considerations (particularly with respect to nuclear facilities), difficulty in obtaining fuel at reasonable prices, and in achieving timely and adequate rate relief from regulatory commissions, effects of energy conservation and limitations on the capacity of the capital market to absorb utility debt.

Water and sewer revenue bonds are generally secured by the fees charged to each user of the service. The issuers of water and sewer revenue bonds generally enjoy a monopoly status and latitude in their ability to raise rates. However, lack of water supply due to insufficient rain, run-off, or snow pack can be a concern and has led to past defaults. Further, public resistance to rate increases, declining numbers of customers in a particular locale, costly environmental litigation, and federal environmental mandates are challenges faced by issuers of water and sewer bonds.

The obligations of any person or entity to pay the principal of and interest on a municipal obligation are subject to the provisions of bankruptcy, insolvency and other laws affecting the rights and remedies of creditors, such as the Federal Bankruptcy Act, and laws, if any, that may be enacted by Congress or state legislatures extending the time for payment of principal or interest, or both, or imposing other constraints upon enforcement of such obligations. Certain bond structures may be subject to the risk that a taxing authority may issue an adverse ruling regarding tax-exempt status.  There is also the possibility that as a result of adverse economic conditions (including unforeseen financial events, natural disasters and other conditions that may affect an issuer’s ability to pay its obligations), litigation or other conditions, the power or ability of any person or entity to pay when due principal of and interest on a municipal obligation may be materially affected or interest and principal previously paid may be required to be refunded. There have been instances of defaults and bankruptcies involving municipal obligations that were not foreseen by the financial and investment communities. The Fund will take whatever action it considers appropriate in the event of anticipated financial difficulties, default or bankruptcy of either the issuer of any municipal obligation or of the underlying source of funds for debt service. Such action may include: (i) retaining the services of various persons or firms (including affiliates of the investment adviser) to evaluate or protect any real estate, facilities or other assets securing any such obligation or acquired by the Fund as a result of any such event; (ii) managing (or engaging other persons to manage) or otherwise dealing with any real estate, facilities or other assets so acquired; and (iii) taking such other actions as the adviser (including, but not limited to, payment of operating or similar expenses of the underlying project) may deem appropriate to reduce the likelihood or severity of loss on the fund’s investment.  The Fund will incur additional expenditures in taking protective action with respect to portfolio obligations in (or anticipated to be in) default and assets securing such obligations.

Historically, municipal bankruptcies have been rare and certain provisions of the U.S. Bankruptcy Code governing such bankruptcy are unclear. Further, the application of state law to municipal obligation issuers could produce varying results among the states or among municipal obligation issuers within a state. These uncertainties could have a significant impact on the prices of the municipal obligations in which the Fund invests.  There could be economic, business or political developments or court decisions that adversely affect all municipal obligations in the same sector.  Developments such as changes in healthcare regulations, environmental considerations related to construction, construction cost increases and labor problems, failure of healthcare facilities to maintain adequate occupancy levels, and inflation can affect municipal obligations in the same sector.  As the similarity in issuers of municipal obligations held by the Fund increases, the potential for fluctuations in the Fund’s share price also may increase.

The secondary market for some municipal obligations issued within a state (including issues that are privately placed with the Fund) is less liquid than that for taxable debt obligations or other more widely traded municipal obligations.  No established resale market exists for certain of the municipal obligations in which the Fund may invest. The market for obligations rated below investment grade is also likely to be less liquid than the market for higher rated obligations. As a result, the Fund may be unable to dispose of these municipal obligations at times when it would otherwise wish to do so at the prices at which they are valued.

Municipal obligations that are rated below investment grade but that, subsequent to the assignment of such rating, are backed by escrow accounts containing U.S. Government obligations may be determined by the investment adviser to be of investment grade quality for purposes of the Fund’s investment policies. In the case of a defaulted obligation, the Fund may incur additional expense seeking recovery of its investment. Defaulted obligations are denoted in the “Portfolio of Investments” in the “Financial Statements” included in the Fund’s reports to shareholders.

The yields on municipal obligations depend on a variety of factors, including purposes of the issue and source of funds for repayment, general money market conditions, general conditions of the municipal bond market, size of a particular offering, maturity of the obligation and rating of the issue. The ratings of Moody’s, S&P and Fitch represent their opinions as to the quality of the municipal obligations which they undertake to rate, and in the case of insurers, other factors including the claims-paying ability of such insurer. It should be emphasized, however, that ratings are based on judgment and are not absolute standards of quality. Consequently, municipal obligations with the same maturity, coupon and rating may have different yields while obligations of the same maturity and coupon with different ratings may have the same yield. In addition, the market price of such obligations will normally fluctuate with changes in interest rates, and therefore the net asset value of the Fund will be affected by such changes.

Option Contracts

See also “Derivative Instruments and Related Risks” herein.  An option contract is a contract that gives the holder of the option, in return for a premium, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the reference instrument underlying the option (or the cash value of the index) at a specified exercise price at any time during the term of the option. The writer of an option on a security has the obligation upon exercise of the option to deliver the reference instrument (or the cash) upon payment of the exercise price or to pay the exercise price upon delivery of the reference instrument (or the cash). Upon exercise of an index option, the writer of an option on an index is obligated to pay the difference between the cash value of the index and the exercise price multiplied by the specified multiplier for the index option. Options may be “covered,” meaning that the party required to deliver the reference instrument if the option is exercised owns that instrument (or has set aside sufficient assets to meet its obligation to deliver the instrument).  Options may be listed on an exchange or traded in the OTC market.  In general, exchange-traded options have standardized exercise prices and expiration dates and may require the parties to post margin against their obligations, and the performance of the parties' obligations in connection with such options is guaranteed by the exchange or a related clearing corporation. OTC options have more flexible terms negotiated between the buyer and the seller, but generally do not require the parties to post margin and are subject to counterparty risk. OTC options also involve greater liquidity risk.  The staff of the SEC takes the position that certain purchased OTC options, and assets used as cover for written OTC options, are illiquid.  Derivatives on economic indicators generally are offered in an auction format and are booked and settled as OTC options.  Options on futures contracts are discussed herein under “Futures Contracts.”

If a written option expires unexercised, the Fund realizes a capital gain equal to the premium received at the time the option was written. If a purchased option expires unexercised, the Fund realizes a capital loss equal to the premium paid. Prior to the earlier of exercise or expiration, an exchange traded option may be closed out by an offsetting purchase or sale of an option of the same series (type, exchange, reference instrument, exercise price, and expiration). A capital gain will be realized from a closing purchase transaction if the cost of the closing option is less than the premium received from writing the option, or, if it is more, a capital loss will be realized. If the premium received from a closing sale transaction is more than the premium paid to purchase the option, the Fund will realize a capital gain or, if it is less, the Fund will realize a capital loss. The principal factors affecting the market value of a put or a call option include supply and demand, the current market price of the reference instrument in relation to the exercise price of the option, the volatility of the reference instrument, and the time remaining until the expiration date.  There can be no assurance that a closing purchase or sale transaction can be consummated when desired.

Straddles are a combination of a call and a put written on the same reference instrument. A straddle is deemed to be covered when sufficient assets are deposited to meet the Fund’s immediate obligations. The same liquid assets may be used to cover both the call and put options where the exercise price of the call and put are the same, or the exercise price of the call is higher than that of the put.  The Fund may also buy and write call options on the same reference instrument to cover its obligations.  Because such combined options positions involve multiple trades, they result in higher transaction costs and may be more difficult to open or close.  In an equity collar, the Fund simultaneously writes a call option and purchases a put option on the same instrument.

To the extent that the Fund writes a call option on an instrument it holds and intends to use such instrument as the sole means of “covering” its obligation under the call option, the Fund has, in return for the premium on the option, given up the opportunity to profit from a price increase in the instrument above the exercise price during the option period, but, as long as its obligation under such call option continues, has retained the risk of loss should the value of the reference instrument decline. If the Fund were unable to close out such a call option, it would not be able to sell the instrument unless the option expired without exercise.  Uncovered calls have speculative characteristics and are riskier than covered calls because there is no instrument or cover held by the Fund that can act as a partial hedge.    

The writer of an option has no control over the time when it may be required to fulfill its obligation under 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 reference instrument at the exercise price. If a put or call option purchased by the Fund is not sold when it has remaining value, and if the market price of the underlying security remains equal to or greater than the exercise price (in the case of a put), or remains less than or equal to the exercise price (in the case of a call), the Fund will lose the premium it paid for the option.  Furthermore, if trading restrictions or suspensions are imposed on options markets, the Fund may be unable to close out a position.

Option Strategy

To the extent described in the Prospectus, the Fund may utilize the Option Strategy.

Real Estate Investment Trusts (“REITs”)

Securities of companies in the real estate industry, such as REITs, are sensitive to factors, such as changes in: real estate values, property taxes, interest rates, cash flow of underlying real estate assets, occupancy rates, government regulations affecting zoning, land use, and rents, and the management skill and creditworthiness of the issuer. Companies in the real estate industry may also be subject to liabilities under environmental and hazardous waste laws, among others. Changes in underlying real estate values may have an exaggerated effect to the extent that REITs concentrate investments in particular geographic regions or property types. Investments in REITs may also be adversely affected by rising interest rates. By investing in REITs, the Fund will bear REIT expenses in addition to its own expenses.

Repurchase Agreements

Repurchase agreements involve the purchase of a security coupled with an agreement to resell at a specified date and price.  In the event of the bankruptcy of the counterparty to a repurchase agreement, recovery of cash may be delayed. To the extent that, in the meantime, the value of the purchased securities may have decreased, a loss could result. Repurchase agreements that mature in more than seven days will be treated as illiquid. Unless the Prospectus states otherwise, the terms of a repurchase agreement will provide that the value of the collateral underlying the repurchase agreement will always be at least equal to the repurchase price, including any accrued interest earned on the agreement, and will be marked to market daily.

Residual Interest Bonds

The Fund may invest in residual interest bonds in a trust that holds municipal securities. The interest rate payable on a residual interest bond bears an inverse relationship to the interest rate on another security issued by t he trust. Because changes in the interest rate on the other security inversely affect the interest paid on the residual interest bond, the value and income of a residual interest bond is generally more volatile than that of a fixed rate bond. Residual interest bonds have interest rate adjustment formulas that generally reduce or, in the extreme, eliminate the interest paid to the Fund when short-term interest rates rise, and increase the interest paid to the Fund when short-term interest rates fall. Residual interest bonds have varying degrees of liquidity, and the market for these securities is relatively volatile. These securities tend to underperform the market for fixed rate bonds in a rising long-term interest rate environment, but tend to outperform the market for fixed rate bonds when long-term interest rates decline. Although volatile, residual interest bonds typically offer the potential for yields exceeding the yields available on fixed rate bonds with comparable credit quality and maturity. These securities usually permit the investor to convert the floating rate to a fixed rate (normally adjusted downward), and this optional conversion feature may provide a partial hedge against rising rates if exercised at an opportune time. While residual interest bonds expose the Fund to leverage risk because they provide two or more dollars of bond market exposure for every dollar invested, they are not subject to the Fund’s restrictions on borrowings.

Under certain circumstances, the Fund may enter into a so-called shortfall and forbearance agreement with the sponsor of a residual interest bond held by the Fund. Such agreements commit the Fund to reimburse the sponsor of such residual interest bond, upon the termination of the trust issuing the residual interest bond, the difference between the liquidation value of the underlying security (which is the basis of the residual interest bond) and the principal amount due to the holders of the floating rate security issued in conjunction with the residual interest bond. Absent a shortfall and forbearance agreement, the Fund would not be required to make such a reimbursement. If the Fund chooses not to enter into such an agreement, the residual interest bond could be terminated and the Fund could incur a loss. The Fund’s investments in residual interest bonds and similar securities described in the Prospectus and this SAI will not be considered borrowing for purposes of the Fund’s restrictions on borrowing described herein and in the Prospectus.

Reverse Repurchase Agreements

Under a reverse repurchase agreement, the Fund temporarily transfers possession of a portfolio instrument to another party, such as a bank or broker-dealer, in return for cash. At the same time, the Fund agrees to repurchase the instrument at an agreed upon time (normally within seven days) and price, which reflects an interest payment. The Fund may enter into a reverse repurchase agreement for various purposes, including, but not limited to, when it is able to invest the cash acquired at a rate higher than the cost of the agreement or as a means of raising cash to satisfy redemption requests without the necessity of selling portfolio assets.  In a reverse repurchase agreement, any fluctuations in the market value of either the securities transferred to another party or the securities in which the proceeds may be invested would affect the market value of the Fund’s assets. As a result, such transactions may increase fluctuations in the value of the Fund.  Because reverse repurchase agreements may be considered to be the practical equivalent of borrowing funds, they constitute a form of leverage.  Such agreements will be treated as subject to investment restrictions regarding "borrowings." If the Fund reinvests the proceeds of a reverse repurchase agreement at a rate lower than the cost of the agreement, entering into the agreement will lower the Fund’s yield.

Royalty Bonds

To the extent described in the Prospectus, the Fund may invest in royalty bonds.

Securities Lending

The Fund may lend its portfolio securities to major banks, broker-dealers and other financial institutions in compliance with the 1940 Act. No lending may be made with any companies affiliated with the investment adviser.  These loans earn income and are collateralized by cash, securities or letters of credit.  The Fund may realize a loss if it is not able to invest cash collateral at rates higher than the costs to enter into the loan.  When the loan is closed, the lender is obligated to return the collateral to the borrower.  The lender could suffer a loss if the value of the collateral is below the market value of the borrowed securities or if the borrower defaults on the loan.  The lender may pay reasonable finder’s, lending agent, administrative and custodial fees in connection with its loans. The investment adviser may instruct the securities lending agent to terminate loans and recall securities with voting rights so that the securities may be voted in accordance with the Fund’s proxy voting policy and procedures if deemed appropriate to do so.

Cash collateral received by the Fund in respect of loaned securities is invested in Eaton Vance Cash Collateral Fund, LLC (“Cash Collateral Fund”), a privately offered investment company holding high quality, U.S. dollar-denominated money market instruments.  The investment objective of Cash Collateral Fund is to provide as high a rate of income as may be consistent with preservation of capital and maintenance of liquidity. Although not a registered money market mutual fund, Cash Collateral Fund conducts all of its investment activities in accordance with the requirements of Rule 2a-7 under the 1940 Act. There can be no assurance that Cash Collateral Fund will be able to maintain a stable net asset value and the Fund could experience a loss of its invested collateral.  Cash Collateral Fund invests in high quality, U.S. dollar-denominated money market instruments of domestic and foreign issuers, including U.S. Government securities and prime commercial paper. When appropriate, Cash Collateral Fund may also invest in other high-grade, short-term obligations, including certificates of deposit, bankers’ acceptances and other short-term securities issued by domestic or foreign banks or their subsidiaries or branches. Cash Collateral Fund may purchase securities on a when-issued basis and for future delivery by means of “forward commitments.” Cash Collateral Fund may enter into repurchase agreements. Cash Collateral Fund may invest without limit in U.S. dollar-denominated obligations of foreign issuers, including foreign banks. Cash Collateral Fund does not limit the amount of its assets that can be invested in one type of instrument or in any foreign country. Information about the portfolio holdings of Cash Collateral Fund is available on request.  As compensation for its services as manager, Eaton Vance is paid a fee at a rate of 0.08% annually of the average daily net assets of Cash Collateral Fund. Eaton Vance pays all of Cash Collateral Fund’s custody, audit and other ordinary operating expenses, excluding extraordinary, non-recurring items such as expenses incurred in connection with litigation, proceedings, claims and reorganization expenses. Payments to Eaton Vance for managing Cash Collateral Fund are in addition to the investment advisory fee paid by the Fund.

A financial institution’s appointment as Agent may usually be terminated in the event that it fails to observe the requisite standard of care or becomes insolvent.  A successor Agent would generally be appointed to replace the terminated Agent, and assets held by the Agent under the Loan Agreement should remain available to holders of Senior Loans. However, if assets held by the Agent for the benefit of the Fund were determined to be subject to the claims of the Agent’s general creditors, the Fund might incur certain costs and delays in realizing payment on a Senior Loan, or suffer a loss of principal and/or interest. In situations involving other Interposed Persons similar risks may arise.

Additional Information. The Fund may purchase and retain in its portfolio a Senior Loan where the borrower has experienced, or may be perceived to be likely to experience, credit problems, including involvement in or recent emergence from bankruptcy reorganization proceedings or other forms of debt restructuring. While such investments may provide opportunities for enhanced income as well as capital appreciation, they generally involve greater risk and may be considered speculative.  The Fund may from time to time participate on ad-hoc committees formed by creditors to negotiate with the management of financially troubled borrowers. The Fund may incur legal fees as a result of such participation.  In addition, such participation may restrict the Fund’s ability to trade in or acquire additional positions in a particular security when it might otherwise desire to do so. Participation by the Fund also may expose the Fund to potential liabilities under bankruptcy or other laws governing the rights of creditors and debtors. The Fund will participate on such committees only when the investment adviser believes that such participation is necessary or desirable to enforce the Fund’s rights as a creditor or to protect the value of a Senior Loan held by the Fund.

In some instances, other accounts managed by the investment adviser may hold other securities issued by borrowers the Senior Loans of which may be held by the Fund. These other securities may include, for example, debt securities that are subordinate to the Senior Loans held by the Fund, convertible debt or common or preferred equity securities.  In certain circumstances, such as if the credit quality of the borrower deteriorates, the interests of holders of these other securities may conflict with the interests of the holders of the borrower’s Senior Loans. In such cases, the investment adviser may owe conflicting fiduciary duties to the Fund and other client accounts. The investment adviser will endeavor to carry out its obligations to all of its clients to the fullest extent possible, recognizing that in some cases, certain clients may achieve a lower economic return, as a result of these conflicting client interests, than if the investment adviser’s client accounts collectively held only a single category of the issuer’s securities.

The Fund may acquire warrants and other equity securities as part of a unit combining a Senior Loan and equity securities of a borrower or its affiliates. The Fund may also acquire equity securities or debt securities (including non-dollar denominated debt securities) issued in exchange for a Senior Loan or issued in connection with the debt restructuring or reorganization of a borrower, or if such acquisition, in the judgment of the investment adviser, may enhance the value of a Senior Loan or would otherwise be consistent with the Fund’s investment policies.

For Floating Rate Portfolio, Senior Portfolio and VT Floating-Rate Income Fund only: The Fund will acquire participations only if the Loan Investor selling the participation, and any other persons interpositioned between the Fund and the Loan Investor (an "Interposed Person"), at the time of investment, has outstanding debt or deposit obligations rated investment grade (BBB or A-3 or higher by S&P or Baa or P- 3 or higher by Moody’s or comparably rated by another nationally recognized statistical ratings organization) or determined by the investment adviser to be of comparable quality. Similarly, the Fund will purchase an assignment or participation or act as a Loan Investor with respect to a syndicated Senior Loan only where the Agent with respect to such Senior Loan at the time of investment has outstanding debt or deposit obligations rated investment grade, or determined by the investment adviser to be of comparable quality.  Notwithstanding the forgoing, the Fund may enter into a transaction to acquire an assignment or participation with an Interposed Person where such Interposed Person does not have outstanding debt or deposit obligations rated investment grade, if the Fund does so in compliance with applicable written procedures governing such transactions.

For additional disclosure relating to investing in loans (including Senior Loans), see “Loans” above.

Short Sales

Short sales are transactions in which a party sells a security it does not own in anticipation of a decline in the market value of that security. To complete such a transaction, the party must borrow the security to make delivery to the buyer. When the party is required to return the borrowed security, it typically will purchase the security in the open market. The price at such time may be more or less than the price at which the party sold the security. Until the security is replaced, the party is required to repay the lender any dividends or interest, which accrues during the period of the loan. To borrow the security, it also may be required to pay a premium, which would increase the cost of the security sold. The net proceeds of the short sale will be retained by the broker, to the extent necessary to meet margin requirements, until the short position is closed out. Transaction costs are incurred in effecting short sales. A short seller will incur a loss as a result of a short sale if the price of the security increases between the date of the short sale and the date on which it replaces the borrowed security. A gain will be realized if the price of the security declines in price between those dates. The amount of any gain will be decreased, and the amount of any loss increased, by the amount of the premium, dividends or interest the short seller may be required to pay, if any, in connection with a short sale. Short sales may be “against the box” or uncovered.  In a short sale “against the box,” at the time of the sale, the short seller owns or has the immediate and unconditional right to acquire the identical security at no additional cost.  In an uncovered short sale, the short seller does not own the underlying security and, as such, losses from uncovered short sales may be significant.  The Fund may sell short securities representing an index or basket of securities whose constituents the Fund holds in whole or in part. A short sale of an index or basket of securities will be a covered short sale if the underlying index or basket of securities is the same or substantially identical to securities held by the Fund.  Use of short sales is limited by the Fund’s non-fundamental restriction relating thereto.

Short-Term Trading

Fixed-income securities may be sold in anticipation of market decline (a rise in interest rates) or purchased in anticipation of a market rise (a decline in interest rates) and later sold. In addition, such a security may be sold and another purchased at approximately the same time to take advantage of what is believed to be a temporary disparity in the normal yield relationship between the two securities. Yield disparities may occur for reasons not directly related to the investment quality of particular issues or the general movement of interest rates, such as changes in the overall demand for or supply of various types of fixed-income securities or changes in the investment objectives of investors.  

Smaller Companies

The investment risk associated with smaller companies is higher than that normally associated with larger, more established companies due to the greater business risks associated with small size, the relative age of the company, limited product lines, distribution channels and financial and managerial resources. Further, there is typically less publicly available information concerning smaller companies than for larger companies. The securities of small companies are often traded only over-the-counter and may not be traded in the volumes typical of trading on a national securities exchange. As a result, stocks of smaller companies are often more volatile than those of larger companies, which are often traded on a national securities exchange.

Stripped Mortgage-Backed Securities (“SMBS”)

SMBS are multiclass mortgage securities. SMBS commonly involve two classes of securities that receive different proportions of the interest and principal distributions on a pool of mortgage assets. A common type of SMBS will have one class receiving most of the interest from the mortgages, while the other class will receive most of the principal. In the most extreme case, the interest only class receives all of the interest while the principal only class receives the entire principal. The yield to maturity on an interest only class is extremely sensitive to the rate of principal payments (including pre-payments) on the related underlying mortgage assets, and a rapid rate of principal payments may have a material adverse effect on the yield to maturity from these securities. If the underlying mortgages experience greater than anticipated prepayments of principal, the initial investment in these securities may not be recouped. Although the market for such securities is increasingly liquid, certain SMBS may not be readily marketable and will be considered illiquid. The market value of the class consisting entirely of principal payments generally is unusually volatile in response to changes in interest rates. The yields on a class of SMBS that receives all or most of the interest from mortgages are generally higher than prevailing market yields on other MBS because their cash flow patterns are more volatile and there is a greater risk that the initial investment will not be fully recouped.

Credit Default Swaps.  Under a credit default swap agreement, the protection “buyer” in a credit default contract is generally obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the contract, provided that no credit event, such as a default, on a reference instrument has occurred. If a credit event occurs, the seller generally must pay the buyer the “par value” (full notional value) of the reference instrument in exchange for an equal face amount of the reference instrument described in the swap, or the seller may be required to deliver the related net cash amount, if the swap is cash settled. If the Fund is a buyer and no credit event occurs, the Fund may recover nothing if the swap is held through its termination date. As a seller, the Fund generally receives an upfront payment or a fixed rate of income throughout the term of the swap provided that there is no credit event. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.  The determination of a credit event under the swap agreement will depend on the terms of the agreement and may rely on the decision of persons that are not a party to the agreement.  The Fund’s obligations under a credit default swap agreement will be accrued daily (offset against any amounts owed to the Fund).

Inflation Swaps.  Inflation swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of fixed rate payments for floating rate payments or an exchange of floating rate payments based on two different reference indices. By design, one of the reference indices is an inflation index, such as the Consumer Price Index. Inflation swaps can be designated as zero coupon, where both sides of the swap compound interest over the life of the swap and then the accrued interest is paid out only at the swap’s maturity.

Total Return Swaps. Total return swap agreements are contracts in which one party agrees to make periodic payments to another party based on the change in market value of the assets underlying the contract, which may include a specified security, basket of securities or securities indices during the specified period, in return for periodic payments based on a fixed or variable interest rate or the total return from other underlying assets. Total return swap agreements may be used to obtain exposure to a security or market without owning or taking physical custody of such security or investing directly in such market. Total return swap agreements may effectively add leverage to the Fund’s portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap. Generally, the Fund will enter into total return swaps on a net basis (i.e., the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments). The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each total return swap will be accrued on a daily basis.  If the total return swap transaction is entered into on other than a net basis, the full amount of the Fund’s obligations will be accrued on a daily basis, and the full amount of the Fund’s obligations will be segregated by the Fund in an amount equal to or greater than the market value of the liabilities under the total return swap or the amount it would have cost the Fund initially to make an equivalent direct investment, plus or minus any amount the Fund is obligated to pay or is to receive under the total return swap agreement.

Interest Rate Swaps, Caps and Floors. Interest rate swaps are OTC contracts in which each party agrees to make a periodic interest payment based on an index or the value of an asset in return for a periodic payment from the other party based on a different index or asset. The purchase of an interest rate floor entitles the purchaser, to the extent that a specified index falls below a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate floor. The purchase of an interest rate cap entitles the purchaser, to the extent that a specified index rises above a predetermined interest rate, to receive payments of interest on a notional principal amount from the party selling such interest rate cap.  The Fund usually will enter into interest rate swap transactions on a net basis (i.e., the two payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments). The net amount of the excess, if any, of the Fund’s obligations over its entitlements with respect to each interest rate swap will be accrued on a daily basis. If the interest rate swap transaction is entered into on other than a net basis, the full amount of the Fund’s obligations will be accrued on a daily basis.  Certain federal income tax requirements may limit the Fund’s ability to engage in certain interest rate transactions.

Swaptions

See also “Derivative Instruments and Related Risks” herein.  A swaption is a contract that gives a counterparty the right (but not the obligation) in return for payment of a premium, to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. The Fund may write (sell) and purchase put and call swaptions. Depending on the terms of the particular option agreement, the Fund will generally incur a greater degree of risk when it writes a swaption than it will incur when it purchases a swaption. When the Fund purchases a swaption, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swaption, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement.

Tax-Managed Investing

Taxes are a major influence on the net returns that investors receive on their taxable investments. There are four components of the returns of a mutual fund that invests in equities that are treated differently for federal income tax purposes: price appreciation, distributions of qualified dividend income, distributions of other investment income, and distributions of realized short-term and long-term capital gains. Distributions of income other than qualified dividend income and distributions of net realized short-term gains (on stocks held for one year or less) are taxed as ordinary income.  Distributions of qualified dividend income and net realized long-term gains (on stocks held for more than one year) are currently taxed at rates up to 20%. The Fund’s investment program and the tax treatment of Fund distributions may be affected by IRS interpretations of the Code and future changes in tax laws and regulations. Returns derived from price appreciation are untaxed until the shareholder disposes of his or her shares. Upon disposition, a capital gain (short-term, if the shareholder has held his or her shares for one year or less, otherwise long-term) equal to the difference between the net proceeds of the disposition and the shareholder’s adjusted tax basis is realized.

Trust Certificates

Trust certificates are investments in a limited purpose trust or other vehicle formed under state law. Trust certificates in turn invest in instruments, such as credit default swaps, interest rate swaps, preferred securities and other securities, in order to customize the risk/return profile of a particular security. Like an investment in a bond, investments in trust certificates represent the right to receive periodic income payments (in the form of distributions) and payment of principal at the end of the term of the certificate. However, these payments are conditioned on the trust’s receipt of payments from, and the trust’s potential obligations to, the counterparties to the derivative instruments and other securities in which the trust invests. Investments in these instruments are indirectly subject to the risks associated with derivative instruments, including, among others, credit risk, default or similar event risk, counterparty risk, interest rate risk, leverage risk and management risk. It is expected that the trusts that issue credit-linked trust certificates will constitute “private” investment companies, exempt from registration under the 1940 Act. Although the trusts are typically private investment companies, they are generally not actively managed. It is also expected that the certificates will be exempt from registration under the 1933 Act. Accordingly, there may be no established trading market for the certificates and they may constitute illiquid investments.

U.S. Government Securities

U.S. Government securities include: (1) U.S. Treasury obligations, which differ in their interest rates, maturities and times of issuance, including: U.S. Treasury bills (maturities of one year or less); U.S. Treasury notes (maturities of one year to ten years); and U.S. Treasury bonds (generally maturities of greater than ten years); and (2) obligations issued or guaranteed by U.S. Government agencies and instrumentalities, which are supported by any of the following: (a) the full faith and credit of the U.S. Treasury; (b) the right of the issuer to borrow an amount limited to a specific line of credit from the U.S. Treasury; (c) discretionary authority of the U.S. Government to purchase certain obligations of the U.S. Government agency or instrumentality; or (d) the credit of the agency or instrumentality. U.S. Government securities also include any other security or agreement collateralized or otherwise secured by U.S. Government securities.  Agencies and instrumentalities of the U.S. Government include but are not limited to: Farmers Home Administration, Export-Import Bank of the United States, Federal Housing Administration, Federal Land Banks, Federal Financing Bank, Central Bank for Cooperatives, Federal Intermediate Credit Banks, Farm Credit Bank System, Federal Home Loan Banks, Federal Home Loan Mortgage Corporation, Federal National Mortgage Association, General Services Administration, Government National Mortgage Association, Student Loan Marketing Association, United States Postal Service, Maritime Administration, Small Business Administration, Tennessee Valley Authority, Washington D.C. Armory Board and any other enterprise established or sponsored by the U.S. Government. The U.S. Government generally is not obligated to provide support to its instrumentalities.  The principal of and/or interest on certain U.S. Government securities could be: (a) payable in foreign currencies rather than U.S. dollars; or (b) increased or diminished as a result of changes in the value of the U.S. dollar relative to the value of foreign currencies. The value of such portfolio securities denominated in foreign currencies may be affected favorably by changes in the exchange rate between foreign currencies and the U.S. dollar.  For additional information about Federal Home Loan Mortgage Corporation and Federal National Mortgage Association, see “Events Regarding FNMA and FHLMC” herein.

Unlisted Securities

Unlisted securities are neither listed on a stock exchange nor traded over-the-counter. Unlisted securities may include investments in new and early stage companies, which may involve a high degree of business and financial risk that can result in substantial losses and may be considered speculative. Such securities will generally be deemed to be illiquid. Because of the absence of any public trading market for these investments, it may take longer to liquidate these positions than would be the case for publicly traded securities. Although these securities may be resold in privately negotiated transactions, the prices realized from these sales could be less than those originally paid or less than what may be considered the fair value of such securities. Furthermore, issuers whose securities are not publicly traded may not be subject to public disclosure and other investor protection requirements applicable to publicly traded securities. If such securities are required to be registered under the securities laws of one or more jurisdictions before being resold, the Fund may be required to bear the expenses of registration. In addition, in foreign jurisdictions any capital gains realized on the sale of such securities may be subject to higher rates of foreign taxation than taxes payable on the sale of listed securities.

Utility and Financial Service Companies

To the extent described in the Prospectus, the Fund may concentrate its investments in utility and/or financial services companies.

Variable Rate Obligations

Variable rate instruments provide for adjustments in the interest rate at specified intervals (daily, weekly, monthly, semiannually, etc.) based on market conditions, credit ratings or interest rates and the investor may have the right to “put” the security back to the issuer or its agent. Variable rate obligations normally provide that the holder can demand payment of the obligation on short notice at par with accrued interest and which are frequently secured by letters of credit or other support arrangements provided by banks. To the extent that such letters of credit or other arrangements constitute an unconditional guarantee of the issuer’s obligations, a bank may be treated as the issuer of a security for the purposes of complying with the diversification requirements set forth in Section 5(b) of the 1940 Act and Rule 5b-2 thereunder. The Fund would anticipate using these bonds as cash equivalents pending longer term investment of its funds.  The rate adjustment features tend to limit the extent to which the market value of the obligations will fluctuate.

Warrants

See also “Derivative Instruments and Related Risks” herein.  Warrants are an option, but not the obligation, to purchase an instrument at a fixed price valid for a specific period of time. Warrants typically are issued by the issuer of the underlying reference instrument. Warrants do not represent ownership of the instrument, but only the right to buy it. The prices of warrants do not necessarily move parallel to the prices of the underlying reference instruments. Warrants may become valueless if not sold or exercised prior to their expiration.  Warrants have no voting rights, pay no dividends and have no rights with respect to the assets of the corporation issuing them. These factors can make warrants more speculative than other types of investments. (Canadian special warrants issued in private placements prior to a public offering are not considered warrants.)

When-Issued Securities, Delayed Delivery and Forward Commitments

Securities may be purchased on a “forward commitment,” “when-issued” or “delayed delivery” basis (meaning securities are purchased or sold with payment and delivery taking place in the future) in order to secure what is considered to be an advantageous price and yield at the time of entering into the transaction.  When the Fund agrees to purchase such securities, it assumes the risk of any decline in value of the security from the date of the agreement to purchase.  The Fund does not earn interest on the securities it has committed to purchase until they are paid for and delivered on the settlement date.

From the time of entering into the transaction until delivery and payment is made at a later date, the securities that are the subject of the transaction are subject to market fluctuations. In forward commitment, when-issued or delayed delivery transactions, if the seller or buyer, as the case may be, fails to consummate the transaction, the counterparty may miss the opportunity of obtaining a price or yield considered to be advantageous. However, no payment or delivery is made until payment is received or delivery is made from the other party to the transaction.

Zero Coupon Bonds

Zero coupon bonds are debt obligations that do not require the periodic payment of interest and are issued at a significant discount from face value. The discount approximates the total amount of interest the bonds will accrue and compound over the period until maturity at a rate of interest reflecting the market rate of the security at the time of purchase. The effect of owning debt obligations that do not make current interest payments is that a fixed yield is earned not only on the original investment but also, in effect, on all discount accretion during the life of the debt obligation. This implicit reinvestment of earnings at a fixed rate eliminates the risk of being unable to invest distributions at a rate as high as the implicit yield on the zero coupon bond, but at the same time eliminates the holder’s ability to reinvest at higher rates in the future. For this reason, zero coupon bonds may be subject to substantially greater price fluctuations during periods of changing market interest rates than are comparable securities that pay interest currently. The Fund is required to accrue income from zero coupon bonds on a current basis, even though it does not receive that income currently in cash, and the Fund is required to distribute that income for each taxable year. Thus, the Fund may have to sell other investments to obtain cash needed to make income distributions.
