+Composition of the Committee
+============================
+
+#. The Finance Committee is composed of 4 people from the Astropy Community and an administrative support person as a non-voting member. The Committee may choose to have a Chair. Decisions that require votes of the Finance Committee (described in APE 19) may be made by three committee members; or two members, one of whom is the Chair. In the event of a tie (2 for and 2 against), the Chair’s vote breaks the tie. In most circumstances, the Chair should be the primary point of contact with NumFocus staff while keeping the entire committee aware of any communications. If none of the Committee members are members of the CoCo, the Chair typically will serve as the liaison to the CoCo.
