Chapter 10Cash Concentration • Order Order Sale Payment Sent Cash • Placed Received Received • Accounts Collection • < Inventory > < Receivable > < Float > • Time ==> • Accounts Disbursement • < Payable > < Float > • Invoice Received Payment Sent Cash Disbursed
Learning Objectives • Understand the need for a cash concentration system. • Formulate a cash transfer decision model. • Understand the advantages and disadvantages of the different cash transfer tools.
Basic Structure • Exhibit 10.1 • Cash transfer tools • Initiation of the transfer • System costs • Benefits of the system

Cash Transfer Tools • Depository transfer checks • ACH or EDT • Wire transfer
Initiation of the Transfer • Decentralized • Centralized
System Costs • Opportunity cost of idle balances • Transfer costs • Administrative costs
Benefits of the System • Economies of scale • Enhanced visibility and control of balances • Dual balance possibilities

Cash Transfer Scheduling • Complicating factors • Objective: minimize transfer costs • Transfer rules
Complicating Factors • Minimum transfer balance • Set incremental cost = Days Saved x ((k - ecr(1-rr)) x TBAL • Solve for TBAL • TBAL = Incremental cost/DS x [k - ecr(1-rr)/365] • Fluctuating daily deposits • Deposits with different availabilities • Availability of deposits vs. clearing of transfer instrument • Weekends
Objective: Minimize Transfer Costs • Subject To: adequate bank compensation • TC = Fee + (k x (ACB - RCB))Where:RCB = (SC - Fee)/ecr(1-rr)
Transfer Rules • Daily transfer: transfer the daily deposit • Managing about a target: • one-time transfer out to earn interest • reduces the number of transfers • Anticipation: initiate transfer prior to deposit
Summary • A collection system such as a lockbox necessitates the development of a concentration system. • This chapter discussed the structure of a cash concentration system and identified the advantages and disadvantages. • The chapter developed an objective function for the cash transfer scheduling problem. • Three transfer scheduling rules were identified and discussed. • The chapter concluded by comparing cash concentration characteristics.
