Factors Affecting Performance [Text Block]

What impacted Fund performance over the reporting period?

U.S. Treasury Inflation Protected Securities (“TIPS”) inflation breakeven spreads moved lower over the course of the reporting period ending December 31, 2025, yet oscillated a bit throughout the period. 1-year and 2-year breakevens experienced a widening in late October before trending tighter throughout the remaining year. Over the reporting period, the short-to-intermediate segment of the TIPS yield curve, represented by the Bloomberg U.S. Treasury TIPS 1-5 Years Index, underperformed the total aggregate bond market, defined by the Bloomberg Barclays Capital US Aggregate Bond Total Return Index, by 174 basis points (“bps”). Over the reporting period, 1-year and 2-year real yields moved lower, which benefited the Fund, while 3-year, 4-year, and 5-year real rates moved higher, which was a detractor for the Fund’s performance.

The Fund seeks to provide periodic inflation-linked distributions through U.S. TIPS, consisting of income and/or principal through 2030 (the "terminal year"). The Fund seeks to achieve its investment objective by employing a “laddered” bond strategy, pursuant to which the Fund will invest in TIPS with different maturity dates (or “rungs”) through the terminal year.

For the reporting period ending December 31, 2025, the Fund's performance on a net asset value ("NAV") basis was 1.06%, differing from the 1.12% return of the Bloomberg U.S. Treasury TIPS 1-5 Years Index, which is reflective of the Fund’s management fee (-10 basis points "bps"), and small net positive contributions from duration/curve positioning (+4 bps), due to the nature of the laddered rung structure relative to a market-weighted reference benchmark.

Factors Affecting Performance [Text Block]

What impacted Fund performance over the reporting period?

For the reporting period ending December 31, 2025, the municipal bond market ended with solid performance. Municipals outpaced both U.S. Treasuries and broader bond markets during this period. The Fund’s performance was impacted by overall municipal market strong demand, outpacing supply.

The Fund seeks to provide periodic distributions consisting of income exempt from regular federal income tax and/or principal through 2030 (the "terminal year"). The Fund seeks to achieve its investment objective by employing a “laddered” bond strategy, pursuant to which the Fund will invest in debt instruments that pay interest that is exempt from regular federal income tax with different maturity dates (or “rungs”) through the terminal year.

For the reporting period ending December 31, 2025, the Fund's performance on a net asset value ("NAV") basis was 0.79%, differing from the 0.95% return of the Bloomberg Municipal 1-5 Year Blend Index. Security selection (-9 basis points "bps") and curve (-7 bps) accounted for the difference.

What impacted Fund performance over the reporting period?

For the reporting period ending December 31, 2025, the municipal bond market ended with solid performance. Municipals outpaced both U.S. Treasuries and broader bond markets during this period. The Fund’s performance was impacted by overall municipal market strong demand, outpacing supply.

The Fund is passively managed and seeks to track the investment results that correspond generally to the price and yield performance, before fees and expenses, of the ICE All Maturity Focused Municipal Bond Index (the “Underlying Index”). Under normal circumstances, the Fund will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in debt instruments that pay interest that is exempt from regular federal income tax.

For the reporting period ending December 31, 2025, the Fund's performance on a net asset value ("NAV") basis was 4.05%, differing from the 3.88% return of the Underlying Index. Security selection/trading (+17 basis points "bps") accounted for the difference.
