Material Conflicts of Interest

Potential conflicts of interest may arise in connection with the Portfolio Managers’ management of the Fund’s investments and the management of the investments of “other accounts”. The other accounts may have the same investment objective as the Fund but may be subject to different management fee structures than the Fund. Therefore, a potential conflict of interest may arise as a result of the similarities in investment objectives and strategies, whereby a Portfolio Manager could favor one account over another. Another potential conflict could include the Portfolio Managers’ knowledge about the size, timing and possible market impact of Fund trades, whereby the Portfolio Managers could use this information to the advantage of other accounts and to the disadvantage of the 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.

Conflicts of Interest Relating to Accounts Investing in the same Portfolio Company

Conflicts may arise in cases where different CrossingBridge clients as well as affiliate clients invest in different parts of an issuer’s capital structure, including circumstances in which one or more CrossingBridge clients as well as affiliate clients may own private securities of an issuer and other CrossingBridge clients as well as affiliate clients may own public securities of the same issuer. For example, a CrossingBridge client or an affiliate client may acquire a loan assignment or fixed income security of a particular borrower in which one or more CrossingBridge clients or affiliate clients have an equity investment. In negotiating the terms and conditions of any such investments, or any subsequent amendments, CrossingBridge may find that the interests of some clients may conflict with the interests of other CrossingBridge clients or affiliate clients. If an issuer in which a CrossingBridge client and one or more other CrossingBridge client as well as affiliate clients hold different classes of securities (or other assets, instruments, obligations issued by such issuer) encounters financial problems, decisions over the terms of any workout may raise conflicts of interest (including conflicts over proposed waivers and amendments to debt covenants). For example, a debt holder may be better served by a liquidation of the issuer in which it may be paid in full, whereas an equity holder might prefer a reorganization that holds the potential to create or retain value for the equity holders. Further, investing in different parts of the capital structure may also result in a conflict between clients with regards to corporate events and proxy voting. CrossingBridge clients that invest in different rankings within the capital structure may have different economic outcomes than originally expected.

CrossingBridge has adopted policies and procedures intended to prevent and mitigate such potential conflicts of interest. This includes, but is not limited to, the review of transactions by CrossingBridge’s compliance department. While CrossingBridge will attempt to resolve such matters fairly, Fund shareholders should be aware that conflicts will not necessarily be resolved in favor of the Fund or Fund shareholders’ interests.

Portfolio Managers’ Compensation

Mr. Sherman and Mr. Rolfe each receive a fixed base salary and incentive awards based on the profitability of the Adviser and the satisfaction of the account objectives. Further, Mr. Sherman, as President of the Adviser, participates in the overall profitability of the firm and may receive distributions. The Portfolio Managers also participate in a retirement plan.
