limits.$TimeHZLWhen the cash balance reaches the upper control limit H cash is invested elsewhere to get us to the target cash balance Z.When the cash balance reaches the lower control limit,L,investments are sold to raise cash to get us up to the target cash balance.McGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-9The Miller-Orr Model MathGiven L,which is set by the firm,the Miller-Orr model solves for Z and Hwhere s2 is the variance of net daily cash flows.The average cash balance in the Miller-Orr model is McGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-10Implications of the Miller-Orr ModelTo use the Miller-Orr model,the manager must do four things:1.Set the lower control limit for the cash balance.2.Estimate the standard deviation of daily cash flows.3.Determine the interest rate.4.Estimate the trading costs of buying and selling securities.The model clarifies the issues of cash management:The best return point,Z,is positively related to trading costs,F,and negatively related to the interest rate K.Z and the average cash balance are positively related to the variability of cash flows.McGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-11Other Factors Influencing the Target Cash BalanceBorrowingBorrowing is likely to be more expensive than selling marketable securities.The need to borrow will depend on managements desire to hold low cash balances.Compensating BalanceFirms have cash in the bank as a compensation for banking services.Large corporations have thousands of accounts with several dozen bankssometimes it makes more sense to leave cash alone than to manage each account on a daily basis.McGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-12FloatThe difference between bank cash and book cash is called float.Float management involves controlling the collection and disbursement of cash.McGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-1328.3 Managing the Collection and Disbursement of

fundsMcGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-17DraftsFirms sometimes use drafts instead of checks.Drafts differ from checks because they are not drawn on a bank but on an issuer(the firm)and are payable by the issuer.The bank acts only as an agent,presenting the draft to the issuer for payment.When the draft is transmitted to a firms bank for collection,the bank must present the draft to the issuing firm for acceptance before making payment.After the draft has been accepted,the firm must deposit the necessary cash to cover the payments.This allows the firm to keep less cash on hand.McGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-18Ethical and Legal QuestionsThe financial managers must always work with collected company cash balances and not with the companys book balance,which reflects checks that have been deposited but not collected.If you are borrowing the banks money without their knowledge,you are raising serious ethical and legal questions.McGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-1928.4 Investing Idle CashA firm with surplus cash can park it in the money market.Some large firms and many small ones use money market mutual funds.Firms have surplus cash for three reasons:Seasonal or Cyclical ActivitiesPlanned

cash to conduct transactions and to compensate banks for the various services they render.The optimal amount of cash for a firm to hold depends on the opportunity cost of holding cash and the uncertainty of future cash inflows and outflows.Two transactions models that provide rough guidelines for determining the optimal cash postion are:The Miller-Orr modelThe Baumol modelMcGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-2228.5 Summary&ConclusionsThe firm can make use of a variety of procedures to manage the collection and disbursement of cash in such as way as to speed up the collection of cash and slow down payments.Some methods to speed collections areLockboxesConcentration bankingWire transfersThe financial managers must always work with collected company cash balances and not with the companys book balance.McGraw-Hill/IrwinCopyright 2002 by The McGraw-Hill Companies,Inc.All rights reserved.28-2328.5
