The debt instruments in which the Fund invests include those issued by the U.S. government or its agencies; mortgage-related securities; asset-backed securities; commercial paper and other money market instruments; debt securities issued by foreign governments in developed countries or their agencies; debt securities issued by U.S. and foreign companies in developed countries; and convertible securities and inflation-indexed debt securities. The Fund may invest up to 20% of its assets in securities of developed market foreign issuers that are denominated in foreign currencies, although the Fund will normally limit its foreign currency exposure from these foreign currency-denominated securities and currencies to 10% of its assets. To maintain this 10% limit, the sub-adviser will hedge back any foreign currency-denominated investments exceeding this 10% limit into U.S. dollars by using foreign currency derivatives such as foreign currency futures, options and forward commitments. The Fund may invest beyond the above limits in U.S. dollar-denominated securities of developed market foreign issuers. Duration management is a fundamental part of the management strategy for this Fund. Duration is often used to measure a bonds sensitivity to interest rates. The longer a funds duration, the more sensitive it is to interest rate risk . The shorter a funds duration, the less sensitive it is to interest rate risk . When selecting securities, the sub-adviser: Decides what duration to maintain. Generally, the sub-adviser expects the Funds weighted average duration to be within approximately 2 years (plus or minus) of the duration of the Bloomberg US Aggregate Bond Index. As of December 31, 2024, the duration of the Bloomberg US Aggregate Bond Index was 6.04 years, and the duration of the Fund was 6.67 years. ? Decides how to allocate among short, intermediate and long duration issues and how much should be invested in various types of instruments. ? Chooses companies to invest in by carrying out a credit analysis of potential investments. ? The sub-adviser may also invest in derivatives based on debt securities and frequently uses futures contracts, forward commitments, swaps and options contracts ( i.e., derivatives). Futures contracts are purchased and sold to adjust interest rate exposure (duration) and/or as a substitute for the physical security. Foreign currency futures contracts, forward commitments or options are purchased or sold to gain or increase exposure to various currency markets and/or to hedge against currency fluctuations. Interest rate swaps are used to adjust interest rate exposures and/or as a substitute for the physical security. Credit default swaps are used to manage default risk of an issuer and/or to gain exposure to a portion of the debt market or an individual issuer. Options are primarily purchased to manage interest rate and volatility exposures or are sold to generate income. The sub-adviser may invest in forward commitments ( i.e., securities that are purchased or sold with payment and delivery taking place in the future), such as when issued securities, and mortgage TBA (to be announced) transactions, which are purchased to gain exposure to the mortgage market. The Fund may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as sale-buybacks or dollar rolls). The sub-adviser may sell a holding when it fails to perform as expected or when other opportunities appear more attractive. The Fund may lend its portfolio holdings to certain financial institutions.
