An audit is designed to be an independent review of the financial records and record-keeping procedures. The old treasurer should be available to facilitate the audit of the books (ex: answer questions when called), but she cannot be involved in the details of the review. Basically, it is her work that is being audited, so she can't be impartial and doesn't belong on the committee. Others (who didn't have check-signing authority) should be doing the detailed review. (which means last year's president--assuming she had check signing authoriyu--also shouldn't be on the committee).

I don't see why it would be a conflict of interest for the NEW treasurer to be involved since you didn't have anything to do with the work this past year. You could probably learn a few things by participating in the audit that will help you this coming year.

Our old PTO board wants our audit committee to be comprised of the new board members and the old treasurer. Shouldn't both old and new treasurer be left out of the audit process?? As the new treasurer, I feel like it's a conflict of interest for me to be on the committee. Anyone run into this before??
