Ltd is considering bringing to the market a new product. A market survey was commissioned to assess the potential demand for the product and this showed that product has an expected life of four years. The survey cost ₵70,000 and this is due for payment in four months’ time. On the basis of the survey information as well as internal management accounting information relating to costs, the assistant accountant prepared the following profit forecasts for the period.

YEAR	1 (₵,000)	2 (₵,000	3 (₵,000	4 (₵,000
Sales	190	200	190	135
Costs of sales	(115)	(145)	(110)	(95)
Gross profit	75	55	80	40
Variable overheads	(35)	(32)	(27)	(20)
Fixed overheads	(25)	(25)	(25)	(25)
Market survey written off	(40)	-	-	-
Net profit/(loss)	(25)	(2)	28	(5)

These profit forecasts were viewed with disappointment by the directors and there was a general feeling that the new product should not be launched.
