Question 1 Alpha Electronics Corp (AEC) manufactures and sells a unique intermediate component part that is widely used in various household electronic products. Operating results for the latest three financial years were as follows:

Table 1	2019	2020	2021
Sales	$1,000,000	$800,000	$1,000,000
Cost of goods sold	760,000	512,000	788,500
Gross margin	240,000	288,000	211,500
Selling and administrative expenses	230,000	198,000	230,000
Net operating income / (loss)	$10,000	$90,000	$(18,500)

As the industry matures, the company is facing stiff competition from several regional players. Sales dropped 20% during 2020, against an original expectation of 40,000 units. Production for 2020 was budgeted at 50,000 units so as to build a sufficient buffer to prevent any stock- out situation from unexpected demand surge. The excess stocks from 2020 was carried over into 2021, and accordingly the budgeted production for 2021 was cut.

	2019	2020	2021
Production in units	40,000	50,000	32,000
Sales in units	40,000	32,000	40,000

(b) Refer to the company' operating results reflected in Table 1. create a brief report to AEC's senior management to explain the fluctuations in net operating income from 2019 to 2021. (c) (i) Explain how operations would have differed in 2020 and 2021 if the company had been using Lean Production with the results that ending inventory was zero. (ii) If Lean production has been in use during 2020 and 2021, and the pre- the determined overhead absorption rate is based on 40,000 units per year, compute the company's net operating income/(loss) for each year under absorption costing. Explain the reason for any differences between these income figures and those reported using variable costing. Justify your explanation with a brief computation.
