Potential Conflicts of Interest

The portfolio managers' management of "other accounts" may give rise to potential conflicts of interest in connection with their management of a Fund's investments, on the one hand, and the investments of the other accounts, on the other. The other accounts may have the same investment objective as the Fund for which they serve as portfolio manager. Therefore, a potential conflict of interest may arise as a result of the identical investment objectives, whereby a portfolio manager could favor one account over another. Another potential conflict could include a portfolio manager's knowledge about the size, timing and possible market impact of Fund trades, whereby the portfolio manager could use this information to the advantage of other accounts and to the disadvantage of a Fund.

The Adviser has established policies and procedures to ensure that the purchase and sale of securities among all accounts it manages are fairly and equitably allocated. There can be no assurance that these policies and procedures will be effective, however.

Compensation

Each portfolio manager's compensation is comprised of a base salary and a bonus, which is based on the profitability of the Adviser. Thus, portfolio manager compensation is aligned with the interests of the Adviser's clients, including the Funds and their investors.

Portfolio Managers' Ownership in the Funds

As of July 31, 2024, the dollar range of equity securities in the Funds beneficially owned by the portfolio managers is as follows:

Name of Portfolio Manager	Dollar Range of Equity Securities Owned in the Funds
Abacus FCF Innovation Leaders ETF	Abacus Tactical High Yield ETF	Abacus FCF Real Assets Leaders ETF

Fei Xue	None	None	None
Tom MacDonald	None	None	None
