إجابة السؤال الأول

By behaviour of costs we mean that a cost behaves in either a fixed manner or a variable manner. However, some costs behave in what is known as a semi variable manner which means that such a cost contains both fixed and variable elements to it.

Furthermore, a cost may behave in a linear or in a non linear manner.


إجابة السؤال الثاني


A fixed cost is said to be fixed if that cost tends to remain unchanged in total despite even relatively wide fluctuations in levels of output or activity.

Rental costs are often given as a good example of a cost that is fixed in that the amount of rent paid does not vary no matter how many units are produced or provided.






إجابة السؤال الثالث


A variable cost is said to be variable if the total cost changes in proportion to changes in the levels of output or activity. The rate of change in a variable cost need not be 1: 1. That is, a cost may vary in direct proportion where for every unit change in output there is a unit change in total cost. Alternatively, the total cost may vary in the ratio of 5: 1, or 10: 3 ... The important point is that there is a significant relationship between changes in output and changes in total cost.



إجابة السؤال الرابع


The function y = a + bx represents the function of a straight line and is often used by management accountants when discussing the behaviour of costs. In this context 'a' represents the total fixed cost in a situation, 'b' represents the variable costs per
unit and x the number of units. When 'b' is multiplied by 'x', we obtain the total variable costs.

The function y = a + bx can represent the total costs of an organisation or department or it can represent a semi variable cost.


إجابة السؤال الخامس

The relevant range is that range of output or activity of which an organisation has direct experience. By direct experience we might mean output that has fallen within that range over a period of time. We might also mean the organisation has carried out sufficiently detailed analyses for it to feel confident of how it believes costs will behave within that range of output or activity.

إجابة السؤال السادس

6 - What part can management policy play in the analysis of cost behaviour ?

If management determines the assignment of costs based on their predetermined ideas of how costs are behaving, then this management action and policy will preclude the need for any further analysis. When management predetermines the assignment of costs, there is no need to attempt an analysis of cost behaviour, since the answer is known in advance by the management!

Although costs may be assigned in line with management policy, there must be periodic reviews of cost behaviour otherwise, management's assignment basis may prove to be open to ridicule.







إجابة السؤال السابع


Solution
1 - (a) there are two possible solutions to this part of the question, although both approaches should give the same ultimate solution.

either: y = total cost = a + bx

= £100,000 + (£10.50 + 17.50 + 7.00)x
= £100,000 + £35x

or: y = total cost = a + b1x + b2x + b3x

= £100,000 + £10.50x + £17.50x + £7.00x

In the case of output of 20,000 chairs, these alternatives give:

£100,000 + £35.00x20,000
= £100,000 + 700,000
= £800,000

£100,000 + £10.50x20,000 + 17.50x20,000 + 7.00x20,000
= £100,000 + 700,000
= £800,000

(b) Cost card. 20,000 dining chairs.

Variable cost of production
materials 210,000
labour 350,000
overheads 140,000
700,000
Fixed factory overheads 100,000
Total costs of production 800,000

2 -The graph showing variable costs per unit should look like the one below. This diagram represents a perfectly variable cost. Irrespective of how many units are produced, the variable cost per unit remains constant.



The graph showing the fixed costs per unit should look like the following diagram.



In this diagram, we have a perfectly fixed cost. In total, fixed costs remain unchanged no matter how many units are made. On a unit basis, however, the more units are made, the lower the fixed cost per unit becomes. It is this behaviour that gives rise to the assertion that the more we make, the cheaper our products become.

Organisations that have relatively high fixed costs should be very careful about their output levels compared with organisations that have relatively low fixed costs. The reason for the need for such care is that fixed costs tend to be strategic in nature. Strategic costs are likely to be committed and hence cannot be reduced in the short term. An organisation with high total fixed costs therefore needs large output levels to reduce fixed costs per unit to as low a level as possible.


إجابة السؤال الثامن


Conversion costs are the combination of direct labor costs plus manufacturing overhead costs.
You can think of conversion costs as the manufacturing or production costs necessary to convert raw materials into products. Expressed another way, conversion costs are a manufacturer’s product or production costs other than the costs of raw materials.
The term conversion costs often appear in the calculation of the cost of an equivalent unit in a process costing system.


إجابة السؤال التاسع

Process costing is a term used in cost accounting to describe one method for collecting and assigning manufacturing costs to the units produced. Processing cost is used when nearly identical units are mass produced. (Job costing or job order costing is a method used when the units manufactured vary significantly from one another.)
To illustrate process costing, let’s assume that a product requires several processing operations—each of which occurs in a separate department. The costs of Department One for the month of June amount to $150,000 of direct materials and $225,000 of conversion costs (direct labor and manufacturing overhead). If the number of units processed in June in Department One is the equivalent of 100,000 units, the per unit cost of the products processed in Department One in June will be $1.50 for direct materials and $2.25 for conversion costs. These costs will then be transferred to Department Two and its processing costs will be added to the cost of the units.


إجابة السؤال العاشر

Absorption costing means that all of the manufacturing costs are absorbed by the units produced. In other words, the cost of a finished unit in inventory will include direct materials, direct labor, and both variable and fixed manufacturing overhead. As a result, absorption costing is also referred to as full costing or the full absorption method.
Absorption costing is often contrasted with variable costing or direct costing. Under variable or direct costing, the fixed manufacturing overhead costs are not allocated or assigned to (not absorbed by) the products manufactured. Variable costing is often useful for management’s decision-making. However, absorption costing is required for external financial reporting and for income tax reporting.

إجابة السؤال الحادي عشر

Absorption costing could result in an increase in net income if a company increases its production and its inventory. This occurs because fixed manufacturing overhead is allocated to more production units—some of which will be reported as inventory.
To illustrate, let’s assume that a company has no beginning inventory and it has production plans for 100,000 units. Let’s also assume that its annual fixed manufacturing overhead is $600,000. If 100,000 units are produced, the fixed manufacturing cost per unit will be $6 ($600,000 divided by 100,000 units). If the 100,000 units are sold for $20 each, the income statement will report sales revenues of $2,000,000 and its cost of goods sold will include $600,000 of fixed manufacturing overhead.
Now let’s assume that the company decides to produce 120,000 units even though sales are expected to remain at 100,000 units. Because the fixed manufacturing overhead remains at $600,000 the cost per unit for fixed manufacturing overhead will be $5 ($600,000 divided by 120,000 units produced). In this case the company will report the same sales revenues of $2,000,000 (100,000 units sold times $20) but its cost of goods sold will include only $500,000 of fixed manufacturing overhead (100,000 units sold times $5). The company’s balance sheet account Inventory will include $100,000 (20,000 units times $5) of the company’s fixed manufacturing overhead.
As was illustrated above, the income statement will report a lower cost of goods sold when production and inventory increased. A smaller cost of goods sold will mean more gross profit and more net income






إجابة السؤال الثاني عشر


This phrase is used in cost accounting and involves the assigning, applying, or allocating of fixed manufacturing overhead costs to the units produced by a manufacturer.
Three examples of fixed manufacturing overhead costs include
1) Depreciation of the manufacturing equipment
2) The property tax on the factory building
3) The salaries of the factory supervisors
Each of these costs comes in large dollar amounts (they do not occur at a rate of say $1.00 per unit) and none is directly traceable to the products manufactured. The dollar amount of each of these costs will probably not change if the company produces 10% more units or 10% fewer units.
Because the fixed manufacturing overhead costs are indirect product costs (not directly traceable to the products) the accountant allocates (or assigns or applies) these costs to the products on some basis—perhaps on the basis of machine hours or through activity-based costing. While the accountant assigns or allocates these costs, the products are said to be absorbing these fixed manufacturing costs. (Absorption costing, which is required for external financial statements, means that each product’s cost includes direct materials, direct labor, variable manufacturing overhead, and fixed manufacturing overhead.)
Fixed manufacturing overhead cost is usually applied to the products (and is absorbed by the products) through the use of a predetermined annual overhead rate that is based on some planned volume of production. If the actual product volume is less than the planned volume (and the costs are as planned) the fixed manufacturing overhead will be “under-absorbed.” When the actual volume exceeds the planned volume and the costs are as planned, the fixed manufacturing overhead will be “over-absorbed.”


إجابة السؤال الثالث عشر

Overabsorbed is usually used in the context of a manufacturer’s production overhead costs. Since manufacturing overhead costs are not directly traceable to products, they need to be allocated, assigned, or applied to the products through an overhead rate. We also state that the products absorb the overhead costs through the overhead rate.
The overhead rate is normally a predetermined rate—meaning that it was calculated prior to the start of the accounting year by using
1) The expected amount of overhead costs
2) The expected volume of production
Because of these two estimates, it is unlikely that the amount of overhead allocated, applied, assigned, or absorbed will be equal to the actual overhead costs incurred.
If the actual products manufactured are assigned or absorb more overhead through the overhead rate than the actual amount of overhead costs incurred, the products have overabsorbed the overhead costs.
At the end of the accounting year, the amount of the overapplied, overassigned, or overabsorbed overhead is often credited to the cost of goods sold. The reasons are
1) The overabsorbed amount is not significant
2) Most of the products absorbing too much overhead costs have been sold
If the overabsorbed amount is significant, then the amount overabsorbed must be prorated or allocated as a reduction to the cost of the inventories and to the cost of goods sold based on where the overabsorbed overhead costs are residing at the end of the accounting year.





إجابة السؤال الرابع عشر

In cost accounting, manufacturing overhead costs are often assigned to products by using a predetermined overhead rate. The predetermined rate is likely based on an annual manufacturing overhead budget divided by some activity such as the expected number of machine hours. Instead of saying that the manufacturing overhead is assigned, we might say it is allocated, applied or apportioned to the products manufactured during the period. We could also say that the products have absorbed the overhead.
If the amount of overhead assigned to the products manufactured is greater than the amount of overhead actually incurred, the products have overabsorbed the overhead costs. If the amount of overhead assigned to the products is less than the amount of overhead actually incurred, the products have underabsorbed the overhead costs.
The cause of the overabsorption or underabsorption will be some combination of
1) The quantity of products manufactured
2) The actual overhead costs incurred.
The amounts of the overabsorbed and underabsorbed manufacturing overhead are referred to as variances.


إجابة السؤال الخامس عشر

Financial accounting has its focus on the financial statements which are distributed to stockholders, lenders, financial analysts, and others outside of the company. Courses in financial accounting cover the generally accepted accounting principles which must be followed when reporting the results of a corporation’s past transactions on its balance sheet, income statement, statement of cash flows, and statement of changes in stockholders’ equity.
Managerial accounting has its focus on providing information within the company so that its management can operate the company more effectively. Managerial accounting and cost accounting also provide instructions on computing the cost of products at a manufacturing enterprise. These costs will then be used in the external financial statements. In addition to cost systems for manufacturers, courses in managerial accounting will include topics such as cost behavior, break-even point, profit planning, operational budgeting, capital budgeting, relevant costs for decision making, activity based costing, and standard costing.
