Factors Affecting Performance [Text Block]

What drove fund performance during the past 12 months?

  • U.S. Treasury inflation protected securities (TIPS) generated positive performance for the 12-month reporting period as shorter-maturity break-even spreads widened and TIPS benefited from principal adjustments for inflation. Although price increases moderated during the period, inflation remained above the Federal Reserve’s 2% target.

  • Positioning for a steepening of the two-year/10-year portion of the yield curve contributed to the fund’s performance versus the style-specific Bloomberg U.S. 1–5 Year Treasury TIPS Index as shorter-maturity Treasury yields fell more during the period than 10-year yields. The higher coupon income produced by the fund’s holdings was also a positive factor.

  • The fund’s duration positioning hampered performance, including a long posture early in the fourth quarter as yields rose sharply, although this positioning was beneficial at other points in the period. Allocations to options on Treasury futures, which we use to help with interest rate management, also detracted versus the style-specific index. Security selection within the TIPS sector modestly hampered performance.

  • The fund seeks a level of income that is consistent with the current rate of inflation by investing in a diversified portfolio of TIPS as well as short- and intermediate-term investment-grade corporate, government, mortgage-backed, and asset-backed securities. At period-end, our non-TIPS allocations were very low as the risk/reward trade-off of credit sectors appeared to be unappealing at this point in the economic cycle, while TIPS looked attractive amid potentially inflationary tariff policies.
