Mark Hancock Incorporated manufactures a speclalized surgical Instrument called the HAN-20. The firm has grown rapidly in recent years because of the product's low price and high quality. However, sales have declined this year primarily due to Increased competition and a decrease in the surglcal procedures for which the HAN-20 is used. The firm is concerned about the decline in sales and has hired a consultant to analyze the firm's profitability. The consultant was provided the following information: Top management at Hancock explained to the consultant that a difficult business environment for the firm In 2021 and 2022 had caused the firm to reduce its price and production levels and reduce its fixed manufacturing costs in response to the decline in sales. Even with the price reduction, there was a decline in sales in both years. This led to an Increase In Irventory in 2021, which the firm was able to reduce in 2022 by further reducing the level of production. In both years, Hancock's actual production was less than the budgeted level so that the overhead rate for fixed overhead, calculated from budgeted production levels, was too low, and a production volume varlance was calculated to adjust cost of goods sold for the underapplied fixed overhead (the calculation of the production volume varlance is explained fully in Chapter 15 and reviewed brlefly below). The production volume varlance for 2021 was determined from the fixed overhead rate of $175 per unit ( $1,225,000/7,000 budgeted units). Because the actual production level was 600 unlts short of the budgeted level in 2021(7,0006,400), the amount of the production volume varlance in 2021 was 600$175=$105,000. The productlon volume varlance is underapplied because the actual production level is less than budgeted, and the production volume varlance is therefore added back to cost of goods sold to determine the amount of cost of goods sold in the full costing Income statement.
