Specifications include, but are not limited to: A. Account Structure Overview: The County maintains one main Concentration Account through which most activity flows, either directly or indirectly as outlined in ATTACHMENT E. B. Account Descriptions: 1. Concentration Account: a. This account is the main account for most County activity. This includes cash, coin, encoded and un-encoded check deposits, Automated Clearing House (ACH) debits and credits, lockbox deposits, consolidated electronic payments via ACH, state and federal ACH transactions, deposits made by remote capture and wires. The account will also be debited for outgoing wires, Electronic Funds Transfers (EFT’s), ACH transactions, and most returned items. All checks deposited should be credited in accordance with the Offeror’s availability schedule. b. The County currently maintains a compensating balance in the Concentration Account to support activity costs for all services, except for accounts that are required to be interest bearing. c. The Concentration Account should operate on a "target balance" basis, whereby the required balance to support activity charges will become the compensating balance. The objective is to maintain the target balance to support activity charges based on an average balance over a six month period. However, the County will maintain a balance higher than the target as the need arises.
