HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE?
During this period, ABXB was up 2.81% (NAV) and 2.81% (Market) and its benchmark returned 2.71%. On a benchmark relative basis, the best active contributor was iShares J.P. Morgan USD Emerging Markets Bond ETF. The main active detractor was iShares 10-20 Year Treasury Bond ETF. The period was marked by Federal Reserve rate cuts in late 2025 followed by an extended pause as sticky inflation and rising oil prices pushed longer-term Treasury yields higher, weighing on ABXB’s duration exposure. Emerging markets debt was the primary contributor as credit spreads tightened to multi-year lows amid resilient global growth and strong investor demand for yield.  ABXB seeks current income and capital preservation by dynamically allocating across diverse fixed income categories using a trend-following approach that can move to cash during unfavorable market conditions, creating intermediate core bond plus exposure seeking downside protection.

1 On February 18, 2025, all of the assets of a separately managed account (the “Predecessor Account”), which had been managed by the Fund’s investment adviser, Abacus FCF Advisors LLC, since March 18, 2021, and had investment policies, objectives, guidelines and restrictions that were in all material respects equivalent to those of the Fund, were transferred to the Fund in a tax-free transaction (the “Transaction”). Performance shown for periods prior to the date of the Transaction represents the performance of the Predecessor Account. Prior to the date of the Transaction, the Fund had not commenced investment operations. The Predecessor Account was not registered under the Investment Company Act of 1940, as amended (“1940 Act”) and therefore was not subject to certain investment restrictions that are imposed by the 1940 Act on registered investment companies. If the Predecessor Account had been registered under the 1940 Act, the Predecessor Account’s performance may have been adversely affected.
