Evaluation of change in credit policy
Current average collection period = 30 + 10 = 40 days
Current accounts receivable = 6m × 40/ 365 = $657534
The Average collection period under new policy = (0.3 × 15) + (0.7 × 60) = 46.5 days
New level of credit sales = $6.3 million
Accounts receivable after policy change = 6.3 × 46.5/ 365 = $802603
Increase in financing cost = (802603 - 657534) × 0.07 = $10155

Determination of spread
Daily interest rate = 5.11/ 365 = 0.014% per day
Variance of cash flows = 1000 × 1000 = $1000000 per day
Transaction cost = $18 per transaction
Spread = 3 * ((0.75 * transaction cost * variance)/interest rate) 1/3 = 3 * ((0.75 * 18 * 1000000)/ 0.00014)1/3 = 3 * 4585.7 = $13757
Lower limit (set by Renpec Co) = $7500
Upper limit = 7500 + 13757 =$21257
Return point = 7500 + (13757/ 3) = $12086
The Miller-Orr model takes account of improbability in relation to receipts and payment. The cash balance of Renpec Co is permitted to differ between the lower and upper limits calculated by the model. If the lower limit is arrive at an amount of cash equal to the difference between the return point and the lower limit is raised by selling short-term investments. If the upper limit is arrive at an amount of cash equal to the difference between the upper limit and the return point is used to buy short-term investments. The model thus helps Renpec Co to decrease the risk of running out of cash while avoiding the loss of profit caused by having unnecessarily high cash balances.
