Why It Matters
These monthly statements give investors timely visibility into the funds’ recent income/loss and changes in net asset value for March 2026, which helps track short‑term performance and NAV trends. Because the statements are furnished under Rule 4.22, they are provided for transparency but are not treated as fully "filed" for certain legal purposes, so investors should consult the statements and other official filings on the fund website or SEC filings for comprehensive financial information.
