Strategy Narrative [Text Block]	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (“Net Assets”) in core fixed income securities of U.S. and foreign issuers.A fixed income security is a debt instrument issued by a company, government or other entity to borrow money. The issuer typically pays a fixed, variable or floating rate of interest and must repay the amount borrowed, usually at the maturity of the security. Foreign securities include securities of issuers located outside the U.S. or securities quoted or denominated in a currency other than the U.S. dollar. The Fund also enters into transactions in foreign currencies, typically through the use of forward contracts and swap contracts. The Fund may also engage in forward foreign currency transactions for both hedging and non-hedging purposes. The Fund also intends to invest in derivatives, including (but not limited to) forwards, interest rate futures, interest rate swaps and credit default swaps, which are used primarily to hedge the Fund’s portfolio risks, manage the Fund’s duration and/or gain exposure to certain fixed income securities or indices. Under normal market conditions, the Fund will: ◼Have at least 30% of its Net Assets, after considering the effect of currency positions, denominated in U.S. dollars ◼Have investments economically tied to at least three countries, including the United States ◼Seek to meet its investment objective by pursuing investment opportunities in foreign and domestic fixed income securities markets and by engaging in currency transactions to seek to enhance returns and to seek to hedge its portfolio against currency exchange rate fluctuationsCore fixed income securities are fixed income securities that are rated investment grade (i.e., securities rated BBB-, Baa3 or higher by a nationally recognized statistical rating organization (“NRSRO”) or, if unrated, determined by the Investment Adviser to be of comparable credit quality).The Fund may invest more than 25% of its total assets in the securities of corporate and governmental issuers economically tied to each of Canada, Germany, Japan and the United Kingdom as well as in the securities of U.S. issuers. Not more than 25% of the Fund’s total assets will be invested in securities of issuers in any other single foreign country. The Fund may also invest in sovereign and corporate debt securities and other instruments of issuers in emerging market countries (“emerging countries debt”) up to the weight of emerging countries debt in the Fund’s benchmark index plus 10% of its total assets measured at the time of purchase (“Total Assets”). The fixed income securities in which the Fund may invest include: ◼Securities issued or guaranteed by the U.S. government, its agencies, instrumentalities or sponsored enterprises (“U.S. Government Securities”), including agency issued adjustable rate and fixed rate mortgage-backed securities or other mortgage-related securities (“Agency Mortgage-Backed Securities”), and custodial receipts therefor ◼Securities issued or guaranteed by a foreign government or any of its political subdivisions, authorities, agencies, instrumentalities or by supranational entities ◼Corporate debt securities ◼Certificates of deposit and bankers’ acceptances issued or guaranteed by, or time deposits maintained at, U.S. or foreign banks (and their branches wherever located) having total assets of more than $1 billion ◼Commercial paper ◼Privately issued adjustable rate and fixed rate mortgage-backed securities or other mortgage-related securities (“Private Mortgage- Backed Securities” and, together with Agency Mortgage-Backed Securities, “Mortgage-Backed Securities”) and asset-backed securities (including collateralized loan obligations)The Fund may gain exposure to Agency Mortgage-Backed Securities through several methods, including by utilizing to-be-announced (“TBA”) agreements in Agency Mortgage-Backed Securities or through the use of reverse repurchase agreements. TBA agreements for Agency Mortgage-Backed Securities are standardized contracts for future delivery of fixed-rate mortgage pass-through securities in which the exact mortgage pools to be delivered are not specified until shortly before settlement. A reverse repurchase agreement enables the Fund to gain exposure to specified pools of Agency Mortgage-Backed Securities by purchasing them on a forward settling basis and using the proceeds of the reverse repurchase agreement to settle the trade. The Fund may also seek to obtain exposure to fixed income investments through investments in affiliated or unaffiliated investment companies, including exchange-traded funds (“ETFs”). The Fund may invest in fixed income securities rated at least BBB– or Baa3 at the time of purchase, and at least 25% of the Fund’s Total Assets will be invested in fixed income securities rated at least AAA or Aaa at the time of purchase or U.S Government Securities. Securities will either be rated by an NRSRO or, if unrated, determined by the Investment Adviser to be of comparable credit quality. The Fund’s target duration range under normal interest rate conditions is expected to approximate that of the Bloomberg Global Aggregate Bond Index (Gross, USD, Hedged) (the “Index”), plus or minus 2 years, and over the last five years ended June 30, 2026, the duration of the Index has ranged between 6.12 and 7.34 years. “Duration” is a measure of a debt security’s price sensitivity to changes in interest rates. The longer the duration of the Fund (or an individual debt security), the more sensitive its market price to changes in interest rates. For example, if market interest rates increase by 1%, the market price of a debt security with a positive duration of 3 years will generally decrease by approximately 3%. Conversely, a 1% decline in market interest rates will generally result in an increase of approximately 3% of that security’s market price. Subject to the above, there are no limits on the length of remaining maturities of securities held by the Fund. The approximate interest rate sensitivity of the Fund is generally comparable to that of a 6 year bond. The Investment Adviser employs a fundamental investment process that may integrate environmental, social and governance (“ESG”) factors alongside traditional fundamental factors. No one factor or consideration is determinative in the fundamental investment process. The Investment Adviser measures the Fund’s performance against the Bloomberg Global Aggregate Bond Index (Gross, USD, Hedged).
