About the Audit and Finance Subcommittee

The Audit and Finance Subcommittee (AFS) was originally formed by Valley Metro RPTA (RPTA) Board as the Budget and Finance Subcommittee (BFS) in 2006 after the passage of Proposition 400 to provide policy oversight of the expanded financial activities of the RPTA. The RPTA and Valley Metro Rail (VMR) Boards renamed the Subcommittee to the AFS in 2016 and expanded the scope of the AFS to add oversight of internal audit functions and to oversee financial and audit functions of VMR.
