Fund
Under typical market conditions, at least 80% of the Portfolio's total assets will be invested in fixed income securities that are considered investment-grade. The fund predominantly targets debt instruments with maturities occurring within two decades of their settlement date. Furthermore, the Portfolio's weighted average duration will generally be managed to stay within a precise range relative to its benchmark, the Bloomberg U.S. Aggregate Bond Index: it will not exceed the benchmark's duration by more than a quarter year, nor will it be more than one year below the benchmark's duration.
