The SEC has historically raised questions regarding the independence of firms that derive a significant portion of their total revenues from one audit client or group of clients because the SEC staff believes this situation causes CPA firms to

1 Profit excessively from a client or group of clients.

2Depend too heavily on the fees generated by the client or clients.

3 Have a mutuality of interests with the client or group of clients.

4 Place too heavy a burden on the clients financial position.
