Strategy [Heading]	Principal Strategies
Strategy Narrative [Text Block]	In pursuit of the Fund’s investment objective, Hoisington Investment Management Company (HIMCo), the Fund’s Sub-Advisor, will: • Typically invest at least 90% of the Fund’s total assets in U.S. Treasury securities and in repurchase agreements collateralized by such securities. • Adjust the average maturity and effective duration of the Fund’s portfolio based on HIMCo’s assessment of multi-year trends in national and international economic conditions. • Invest in long-term U.S. Treasury bonds, including U.S. Treasury Strips (zero coupon Treasury securities), when HIMCo determines that economic conditions suggest lower inflation and the multi-year trend is toward decreasing interest rates. • Invest in U.S. Treasury bills or notes, Treasury Inflation-Protected Securities (TIPS), and Floating Rate Notes (FRNs) (maturities less than five years) when HIMCo determines that economic conditions suggest rising inflation and the multi-year trend is toward increasing interest rates. Over the course of a business cycle, under normal market conditions: • The effective duration of the Fund’s holdings is expected to vary from less than a year to a maximum of 25 years. • The Fund’s holdings will range in maturity from less than a year to a maximum of the longest maturity Treasury bonds available. As of September 30, 2025, the effective duration of the Fund’s holdings was 20.88 years, and the average maturity of the Fund’s holdings was 24.02 years. • When the Fund is invested in securities with longer weighted average maturities it will be more sensitive to changes in market interest rates and its share price may be subject to greater volatility. • The Fund’s portfolio turnover rate will vary substantially from year to year. During some periods, turnover will be well below 50%. At other times, turnover could exceed 200% annually. At these times, increased portfolio turnover may result in higher transaction costs and may also result in taxable capital gains. • Portfolio adjustments may require the sale of securities prior to their maturity date. The goal of these transactions will be to increase income and/or change the duration of the overall portfolio.
