This formula is a modification of the economic order quantity EOQ) formula used for inventory management. Assume that the ._.set of selling marketable securities is US $10 per transaction and the interest rate on marketable securities is 6% per year. The entity estimates that it will make cash payments of US $12.000 over a one-month period. What is the average cash balance rounded to the nearest dollar)?

  1. US $1, 000
  2. US $2, 000
  3. US $3, 464
  4. US $6, 928

Answer(s): C

Explanation:

The BOO for inventory is a function of ordering cost per order, inventory demand, and carrying cost. In the cash model, the fixed cost per sale of securities is equivalent to the ordering cost, the demand for cash is similar to the demand for inventory, and the interest
rate is effectively the cost of carrying a dollar of cash for the period. Substituting in the formula yields an optimal cash balance of about US $6.928. Thus, the average cash balance is US $3, 464 $6, 928 - 2).



An entity has daily cash receipts of US $300, 000. A bank has offered to provide a lockbox service that will reduce the collection time by 3 days. The bank requires a
monthly fee of US $2, 000 for providing this service. If money market rates are expected to average 6% during the year, the additional annual income loss) of using the lockbox service is

  2. US $12, 000
  3. US $30, 000
  4. US $54, 000

Answer(s): C

Explanation:

Because collections will be accelerated by 3 days at a rate of US $300, 000 per days, the entity will have an additional US $900, 000 to invest. At a rate of 6%, the interest earned will be US $54, 000 per year. However, the bank will charge US $24, 000 $2, 000 per month x 12 months) for its services. Thus, the entity will increase its income by US $30, 000 54, 000 - $24, 000).

  1. Average collection period has decreased.
  2. Percentage discount offered has decreased.
