        <ExplanationTxt>The Trust has a detailed code of Ethics and Conduct, as well as a Conflict of Interest Policy. These policies are reviewed with each new trustee who joins the Board of Trustees as part of orientation. In addition, legal counsel to the Trust reviews the policies and the ERISA and IRS VEBA trust fiduciary obligations with the Trustees on an annual basis, and at additional times if there is any potential for an appearance of a conflict. When potential conflicts have arisen in the pastsuch as when a Trustee is invited on an advisory board of a medical provider, such conflicts are reviewed by the Chair of the Board in consultation with the Trusts legal counsel. Such potential conflicts are disclosed to the full Board of Trustees, which then makes a decision in open session as to whether such potential conflict requires more disclosure or other action, which can include a request to decline the potentially conflicting position or resign the Board of Trustees.</ExplanationTxt>
