Derivatives Risk - Derivatives instruments (such as futures, options, swaps and structured securities) can be highly volatile and involve risks in addition to the risks of the underlying referenced securities. Using derivatives can increase fund losses and reduce opportunities for gains when market prices, interest rates or the derivative instruments themselves behave in a way not anticipated by the Portfolio. Derivatives may be difficult to sell, unwind or value, and the counterparty may default on its obligations to the Portfolio. Changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index and the Portfolio could lose more than the principal amount invested. In addition to investing in derivatives to implement its strategy, the Portfolio may also use derivative instruments for hedging purposes, in an attempt to reduce the risk of loss from falling stock prices or lower foreign currency valuations, increased interest rates or other adverse market developments. There can be no assurance that a hedging technique will work as intended. Portfolio performance may be diminished by the added cost of the derivative instruments.
Foreign Investments Risk - Foreign investments involve risks not normally encountered with domestic securities. These include political, regulatory and economic instability in some countries, the imposition of economic sanctions, changes in currency rates and market inefficiencies. The laws of some foreign countries may limit the Portfolio's ability to invest in securities of certain issuers organized under the laws of those countries. Trade tensions and economic sanctions on individuals and companies can contribute to market volatility. This may adversely impact the Portfolio's performance.
Emerging Markets Risk - Securities issued or traded in emerging markets generally entail greater risks than securities issued or traded in developed markets. Emerging market countries may have relatively unstable governments and may present the risk of nationalization of business, expropriation, confiscatory taxation or, in certain instances, reversion to closed market, centrally planned economies. Differences in regulatory, accounting, auditing and financial reporting and recordkeeping standards could impede the ability to evaluate local companies or impact the Portfolio's performance. The typically small size of the markets of securities of issuers located in emerging markets and the possibility of a low or nonexistent volume of trading in those securities may also result in a lack of liquidity and in price volatility of those securities.
Government Securities Risk - Not all obligations of the U.S. government, its agencies and instrumentalities are backed by the full faith and credit of the U.S. government. Some obligations are backed only by the credit of the issuing agency or instrumentality, and, in some cases, there may be some risk of default by the issuer. Any guarantee by the U.S. government or its agencies or instrumentalities of a security the Portfolio holds does not apply to the market value of the security or to shares of the Portfolio. A security backed by the U.S. Treasury or the full faith and credit of the U.S. government is guaranteed only as to the timely payment of interest and principal when held to maturity. The risks associated with an investment in Credit Risk Transfer securities ("CRTs") differ from the risks associated with an investment in mortgage-backed securities issued by Government Sponsored Enterprises ("GSEs") because, in CRTs, some or all of the credit risk associated with the underlying mortgage loans is transferred to the end-investor.
Interest Rate Risk - Prices of fixed-income securities rise and fall in response to changes in the interest rates paid by similar securities. Generally, when interest rates rise, prices of fixed-income securities fall. However, market factors, such as the demand for particular fixed-income securities, may cause the price of certain fixed-income securities to fall while the prices of other securities rise or remain unchanged. Interest rate changes have a greater effect on the price of fixed-income securities with longer maturities. A wide variety of market factors can affect interest rates. Recent and potential future changes in monetary policy made by central banks and/or their governments are likely to affect the level of interest rates. The Portfolio may be subject to heightened interest rate risk due to certain changes in monetary policy. Rising interest rates may expose fixed-income markets to increased volatility and may reduce the liquidity of certain Portfolio investments. These developments also could cause more fluctuation in the Portfolio's net asset value or make it more difficult for the Portfolio to accurately value its securities. These developments or others could also cause the Portfolio to face increased shareholder redemptions, which could force the Portfolio to liquidate investments at disadvantageous times or prices, therefore adversely affecting the Portfolio as well as the value of your investment. The amount of assets deemed illiquid remaining within the Portfolio may also increase, making it more difficult to meet shareholder redemptions and further adversely affecting the value of the Portfolio.
Issuer Risk - The value of a security may decline for reasons related to the issuer, such as earnings stability, overall financial soundness, management performance and reduced demand for the issuer's goods or services.
Leverage Risk - Leverage risk is created when an investment (such as a derivative transaction) exposes the Portfolio to a level of risk that exceeds the amount invested. Changes in the value of such an investment magnify the Portfolio's risk of loss and potential for gain.
Liquidity Risk - The Portfolio may not be able to sell some or all of its securities at desired prices or may be unable to sell the securities at all, particularly during times of market turmoil. Markets may become illiquid when, for instance, there are few, if any, interested buyers or sellers or when dealers are unwilling or unable to make a market for certain securities. The Portfolio may not be able to sell a restricted or illiquid security at a favorable time or price, thereby decreasing the Portfolio's overall liquidity. Further, the lack of an established secondary market may make it more difficult to value illiquid securities. If the Portfolio is forced to sell an illiquid security to meet redemption requests or for other cash needs, the Portfolio may be forced to sell at a loss.
Lower-Rated Debt Securities Risk - Bonds rated below investment grade, which is defined as BB or lower (also called "junk bonds"), are subject to greater levels of interest rate, credit and liquidity risks. They are considered primarily speculative with respect to the issuer's continuing ability to make principal and interest payments.
