Question

Supreme Chips is a manufacturer of prototype chips based in​ Dublin, Ireland. Next​ year, in 2018​,Supreme Chips expects to deliver 575 prototype chips at an average price of $90,000. Supreme Chips' marketing vice president forecasts growth of 55 prototype chips per year through 2024.
That​ is, demand will be 575 in 2018​,630 in 2019​,685 in 2020​, and so on.

The plant cannot produce more than 545 prototype chips annually. To meet future ​demand,Supreme Chips must either modernize the plant or replace it. The old equipment is fully depreciated and can be sold for $4,700,000. if the plant is replaced. If the plant is​ modernized, the costs to modernize it are to be capitalized and depreciated over the useful life of the updated plant. The old equipment is retained as part of the modernize alternative. The following data on the two options are​ available:

	Modernize		Replace
Initial investment in 2018	$34,800,000		$66,100,000
Terminal disposal value in 2024	$6,600,000		$16,800,000
Useful life	7 years		7 years
Total annual cash operating cost per prototype chip	$74,500		$65,000

Supreme Chips uses​ straight-line depreciation, assuming zero terminal disposal value. For​ simplicity, we assume no change in prices or costs in future years. The investment will be made at the beginning of 2018​, and all transactions thereafter occur on the last day of the year.Supreme ​Chips' required rate of return is 6​%.There is no difference between the modernize and replace alternatives in terms of required working capital. Supreme Chips has a special waiver on income taxes until 2024.

Requirement 1. Sketch the cash inflows and outflows of the modernize and replace alternatives over the 2018​-2024 period.

​First, determine the cash inflows and outflows of the modernize alternative over the 2018 to 2024 period. ​(Use a minus sign or parentheses for a cash outflows. Leave unused cells​ blank.)

	Units	Net cash	Initial	Proceeds from
Year	sold	contributions	investments	sale of equipment
Jan 1, 2018			$(34,800,000)
Dec 31, 2018	575	$8,912,500
Dec 31, 2019	630	9,765,000
Dec 31, 2020	685	10,617,500
Dec 31, 2021	740	11,470,000
Dec 31, 2022	795	12,322,500
Dec 31, 2023	850	13,175,000
Dec 31, 2024	905	14,027,500		$6,600,000

​Next, determine the cash inflows and outflows of the replace alternative over the 2018 to 2024 period. ​(Use a minus sign or parentheses for a cash outflows. Leave unused cells​ blank.)

	Units	Net cash	Initial	Proceeds from
Year	sold	contributions	investments	sale of equipment
Jan 1, 2018			$(66,100,000)	$4,700,000
Dec 31, 2018	575	$14,375,000
Dec 31, 2019	630	15,750,000
Dec 31, 2020	685	17,125,000
Dec 31, 2021	740	18,500,000
Dec 31, 2022	795	19,875,000
Dec 31, 2023	850	21,250,000
Dec 31, 2024	905	22,625,000		$16,800,000

Requirement 2. Calculate payback period for the modernize and replace alternatives. ​(Round your answers to two decimal​ places.)

The payback period for the investment assuming the modernize alternative is ____ years.

3.	Calculate net present value of the modernize and replace alternatives
