How to Manage Accounts Receivable Why Credit Is Offered
How to Manage Cash Two Types of Float Managing Float How to Manage Accounts Receivable Why Credit Is Offered Developing a Credit Policy Cost of Credit Total Cost of Credit Curve and the Optimal Amount of Credit Five Cs of Credit Analysis Collection of Accounts Receivable (Monitoring) Short-Term Financing Alternatives Bank Loans Trade Credit 2
3
Objectives Use economic order quantity to compute optimal inventory
Understand float
4
Use Baumol model to estimate optimal cash
Use Miller-Orr model to estimate optimal cash
5
Inventory Management Inventory is held to prevent stockouts and to increase sales There are costs to holding inventory Opportunity cost of funds Storage cost
6
Insurance cost Obsolescence, damage, and theft
7
(Beginning Inventory - Ending Inventory)
Average Inventory is Computed as (Beginning Inventory - Ending Inventory) 2

The next figure shows how average inventory falls as order frequency increases

The optimal inventory balances the carrying cost of inventory against the reordering cost

Example Order cost is $ Carrying Cost is $3.00. The firm sells 10,000 units per year. What is the optimal inventory?
15
Solution
16
To provide a safety stock the first order can be increased

Other Inventory Methods Include
Just-in-time Basket method

Cash Management 1. Types of float a. Disbursement float
The delay between when a firm issues a check and when the funds are removed from the bank
20
b. Collection float The delay between when you receive payment and when the bank gives you credit c. Net Float = Available Balance– Firm’s Book Value
21
Float management includes speeding up collections and slowing down disbursement
22
Speeding Up Collections
Lockbox Customers mail payment to a mailbox controlled by the bank

Concentration banking
Regional banks receive payments and transfer funds to concentration bank

26
Electronic funds transfer (EFT)
Electronically moves funds between accounts Selecting banks that minimize float because of either location or popularity with customers
27
Slowing Disbursements Increases Cash Balance but Has Hidden Costs
Lost discounts Loss of supplier goodwill may result in increased costs or poor service
28
Optimal Cash Balance Cash is held To meet transaction needs
As a precaution against unexpected events To take advantage of unexpected opportunities
29
The Baumol Model Provides a Method to Compute the Optimal Cash Conversion Amount
30
The Baumol model assumes cash is used at a steady rate
The Baumol model assumes cash is used at a steady rate. If this model does not fit the firm an alternative is the Miller-Orr model When cash on hand reaches an upper limit it is invested When cash reaches a lower limit investments are sold to raise cash
31
FIGURE 16.6 Using the Miller–Orr Model to Compute the Economic Order Quantity

32
x Transaction cost x Variance of Cash Flow interest rate
The spread between the lower limit and upper limit is computed as: spread = 3 [ 3 3 x Transaction cost x Variance of Cash Flow interest rate 4
33
The return point is computed as:
spread 3 Return Point = Lower Limit +
34
Managing Accounts Receivable
Credit is offered to increase sales A credit policy sets the condition for extending credit and must balance credit losses against lost sales
35
FIGURE 16.8 Net Cost of Extending Credit

36
A Credit Policy Includes
Credit period Cash discount Cost of credit
37
Credit Applicants Are Often Evaluated Based on the Five Cs.
1. Character 2. Capacity 3. Capital 4. Conditions 5. Collateral
38
Monitoring Accounts Receivable
Every firm offering credit should regularly prepare an aging schedule
39
Table 16.1 Aging Schedule Age of Account Amount Number of Accounts
0–10 days $100, 11–30 days , 31–45 days , 46–60 days , Over 60 days ,
40
The collection effort must balance credit losses against losing customers. It usually includes the following: Past due letter Personal phone call Account turned over to collection agency Customer sued for payment
41
Short-Term Sources of Funds
1. Bank loans a. Self-liquidating loans b. Lines of credit 2. Trade credit
