The Adviser has adopted proxy voting policies and guidelines for this purpose (“Proxy Voting Policies”), which have been adopted by the Trust as the policies and procedures that will be used when voting proxies on behalf of the Funds.

In the absence of a conflict of interest, the Adviser will generally vote “for” routine proposals, such as the election of directors, approval of auditors, and amendments or revisions to corporate documents to eliminate outdated or unnecessary provisions. Unusual or disputed proposals will be reviewed and voted on a case-by-case basis.
