Advanced: Net present value calculation for the replacement of a machine and a discussion of the conflict between ROI and NPV Eckard pic is a large, all-equity financed, divisionalized textile company whose shares are listed on the London Stock Exchange.

It has a current cost of capital of 15%. The annual performance of its four divisions is assessed by their return on investment (ROI), i.e. net profit after tax divided by the closing level of capital employed. It is expected that the overall ROI for the company for the year ending 31 December 1988 will be 18%, with the towelling division having the highest ROI of 25%. The towelling division has a young, ambitious managing director who is anxious to maintain its ROI for the next two years, by which time he expects to be able to obtain a more prestigious job either within Eckard pic or elsewhere.

He has recently turned down a proposal by his division's finance director to replace an old machine with a more modem one, on the grounds that the old one has an estimated useful life of four years and should be kept for that period. The finance director has appealed to the main board of directors of Eckard pic to reverse her managing director's decision.

The following estimates have been prepared by the finance director for the new machine:

Investment cost £256000, payable on 2 January 1989.

Expected Ide: four years to 31 December 1992.

Disposal value: equal to its tax written down value on 1 January 1992 and receivable on 31 December 1992.

Expected cash flow savings: £60 000 in 1989, rising by 10% in each of the next three years. These cash flows can be assumed to occur at the end of the year in which they arise.

Tax position: the company is expected to pay 35% corporation tax over the next four years. The machine is eligible for a 25% per annum writing down allowance. Corporation tax can be assumed to be paid 12 months after the accounting year-end on 31 December.

No provision for deferred tax is considered to be necessary Old machine to be replaced: this would be sold on 2 January 1989 with an accounting net book value of £50 000 and a tax written down value of nil. Sale proceeds would be £40 000, which would give rise to a balancing charge. If retained for a further four years, the disposal value would be zero.
Relevant accounting policies: the company uses the straight-line depreciation method with a full year's depreciation being charged in both the year of acquisition a11d the year of disposal. The capital employed figure for the division comprises all assets excluding cash.
