According to the OCC Directors Handbook, there are only two committees required by regulation- the audit committe (for banks over $500 million) whose membership should be only outside directors, and a trust audit committee for banks with trust powers. The Book mentions other committees that are recommended, including the Asset/Liability Committee but does not give any qualifications for membership. I am at a very small, family owned bank and our Investment Committee handles Asset/Liability matters. It is comprised of the entire board (all seven of them-three of them owners) and our Controller. If you're a National Bank, check out the Directors Handbook -- it has a lot of good info.
It really doesn't matter, no one listens to me anyway.
