The Fund will ordinarily seek to maintain an average duration of approximately three years or less. With respect to corporate issuers, the Fund will not purchase securities with remaining maturities of more than 5.25 years. The Adviser employs a value approach toward fixed-income investing and makes securities and sector decisions based on the anticipated tradeoff between long-run expected return and risk. The Fund seeks value in the fixed-income market with only a limited sensitivity to changes in interest rates. The Adviser relies upon value measures such as the level of real interest rates, yield curve slopes and credit-adjusted spreads to guide its decisions regarding interest rate, country, sector and security exposure. A team of portfolio managers implements strategies based on these types of value measures. Certain team members focus on specific bonds within each sector. Others seek to ensure that the aggregate risk exposures to changes in the level of interest rates and yield spreads match the Funds objective. The Funds investment process incorporates information about environmental, social and governance issues (also referred to as ESG) via an integrated approach within the investment teams fundamental investment analysis framework. The Adviser may engage with management of certain issuers regarding corporate governance practices as well as what the Adviser deems to be materially important environmental and/or social issues facing a company.
