Yellow Pear plc has sales of 10m per annum. It usually requires its customers to pay at the 20th day. However, on average, its customers pay on the 80th day after the invoice is made. A manager has suggested that a 2.0% discount of the goods can be applied for those customers who pay on the 10th day after the invoice is offered to the customers. He expects that 70% of customers will be attracted to this idea and pay on the 10th day. And this will reduce the company's effort in chasing up the payment from its customers and save 60,000 per annum on administration. But it will also INCREASE the amount of bad debt from the original level of 0.8% of sales to 1% of sales. The other 30% of customers will continue to pay (on average) on the 80th day. The company's overdraft facility costs 15% per annum. Required: (a) Please evaluate the suggestion of the manager and decide whether his suggestion should be accepted. (15 marks) (b) Please evaluate the following statement: taking a long time to pay suppliers' invoice is always a cheap form of finance
