Whats wrong with having a treasurer on the board?
There is nothing wrong with a board’s having a treasurer if there is no CEO. Because of the managerially comprehensive nature of the CEO job, investing a board officer with responsibility for financial integrity constitutes overlapping (and, therefore, dysfunctional) delegation. If an outside authority requires the board to have such an office, the board should seek a way to eliminate any duplication with the CEO. One way would be to charge the treasurer with assisting the board to create and periodically revisit all board policies that bear on financial matters.
