Manufacturing overhead

Cost accounting is the name traditionally given to accounting for manufacturing costs. The manufacturing cost of a product is traditionally taken as the sum of the costs for (1) direct materials, (2) direct labor, (3) manufacturing overheads, and (4) administration, selhng, and finance. 

However, it is sometimes quite difficult to separate costs and particularly manufacturing overhead costs into fixed and variable components. In the long term virtually all costs are variable. The difference between the two methods assumes great importance in inventory evaluation. In cost accounting, costs are identified with cost centers. These are accounting devices which may or may not have a physical existence. In the simplest case of a plant manufacturing a single product, the entire plant may be the cost center. 

As soon as the protein is activated with the heterobifunctional crosslinker, the extinction coefficient determined for pure Amb a 1 no longer applies because the heterobifunctional crosslinker absorbs at 280 nm. At this step in the production of AIC, the manufacturing overhead cost requires the use of a fast protein assay, whereas the exact stoichiometry of the subsequent reaction dictates the use of an accurate and precise method. Hence we developed a new extinction coefficient for the activated protein based on experimental data and demonstrated that within the normal activation range of 9 to 12 crosslinkers per Amb a 1, the new extinction coefficient remained constant. The concentration of the purified activated Amb a 1 determined by this direct absorbance A280 method is more precise and accurate than could be assigned by a colorimetric assay. Consequently, the activated Amb a 1 concentration allows for the accurate addition of 1018 ISS required to consistently produce AIC with optimal activity. 

At the same time an increased proportion of exports will allocate an increased proportion of annual fixed manufacturing overheads to export sales and hence a reduced proportion to UK NHS sales. The effect of this will be to reduce the cost of sales charged to the United Kingdom, with a consequent increase in profit. 

Fixed cost effects are included in most production network design models but scale and scope effects related to variable costs and learning curve effects lead to concave cost functions (cf. Cohen and Moon 1990, p. 274). While these can be converted into piecewise linear cost functions, model complexity increases significantly both from a data preparation perspective (see Anderson (1995) for an approach to measure the impact on manufacturing overhead costs) and the mathematical solution process. Hence, most production network design models assume linear cost functions ignoring scale and scope effects related to variable costs.

The cost of manufacturing a product includes the manufacturing cost, overhead, and general expenses. Manufacturing cost includes direct expenses and consists of the cost of raw material, containers, operator and labor costs, and utilities (like electricity, steam, water, fuel, etc.). This cost will depend on the production quantity. In contrast, overhead cost will be constant irrespective of the quantity of material that is being manufactured. Overhead cost may include expenses such as employee salaries, medical services, administration, insurance, depreciation, taxes, etc. General expenses consist of freight and delivery, sales, and R D expenses. 

Manufacturing overheads are usually entered as an arbitrary fraction of the DMC for each manufacturing unit. 

When the consultant pointed out that the company s distribution costs were equal to its manufacturing costs, management s reaction was, "Yeah, so what " Further questioning by the consultant revealed that, although the company realized that it was just as much a distribution company as it was a manufacturer, it did not see any problem inherent in treating the 2,200,000 of distribution costs as if tiiey were manufacturing overhead. 

Manufacturing cost a variable cost for each product was found by collecting raw material, labour, power, packaging and waste costs. Manufacturing overheads (fixed costs) were allocated on the basis of direct labour. Because of the small difference in manufacturing methods, the manufacturing costs for the two products were similar. They were 2,107 for A and 2,032 for B. 

Inventory is classified differently for retail companies, merchants, and manufacturers. Retailers classify their inventory as merchandise inventory, the merchant owns it and it is ready for sale. Contrastingly, manufacturers and assembly plants categorize their inventory as raw materials, work-in-process, and finished goods. Manufacturers and assemblers classify inventory this way to indicate the condition of the inventory and if it is ready for sale. For example, prior to assembly of an aircraft, an aircraft manufacturer would classify components of the airplane such as tires, wiring, and hydraulic pumps as raw materials. These materials are directly used in production. As soon as assembly starts, the manufacturer would then classify the components as work-in-process. Work-in-process is inventory costs related to direct materials, direct labor, and manufacturing overhead. A completed aircraft ready for sale would be classified as finished goods. As a reminder, all inventories are combined and reported on the balance sheet. 

It is important to note that manufacturing overhead consists of all manufacturing costs other than direct materials and direct labor that is related to production and included in the COGS. Overhead includes factory supplies used and labor not directly identified with the production of specific products. It also includes general manufacturing costs such as depreciation, maintenance, repairs, property taxes, insurance, and utilities. Additionally, a reasonable share of the...
