QUESTION 1(a)

Q Describe four limitations of management accounting
A

Solution


Limitations of Management Accounting


1. Subjectivity and Estimations:

Management accounting often involves making estimates and assumptions, especially when dealing with future projections. These estimates can be subjective and may vary based on the individual making them.

2. Focus on Internal Information:

Management accounting primarily focuses on internal information and is not regulated by external standards. This can lead to a lack of consistency and comparability between organizations, as each may adopt different methods for reporting.


3. Historical Emphasis:

Much of the information provided by management accounting is based on historical data. While historical information is useful for trend analysis, it may not accurately reflect future market conditions or changes in the business environment.


4. Not Subject to External Audit:

Unlike financial accounting, management accounting reports are not subject to external audit or independent verification. This can reduce the reliability of the information presented, as there is no external assurance of accuracy.


5. May Encourage Short-Term Focus:

Management accounting is often geared towards short-term planning and decision-making. This can result in managers making decisions that benefit the organization in the short term but may not be in its long-term best interest.


6. Costly and Time-Consuming:

Implementing and maintaining a management accounting system can be costly and time-consuming. Small businesses, in particular, may find it challenging to allocate resources to develop and maintain a sophisticated management accounting system.


7. Dependency on Financial Metrics:

Management accounting often relies heavily on financial metrics such as budgets, variances, and ratios. This financial focus may not capture important non-financial factors that can influence the performance and success of an organization.


8. Influence of Organizational Culture:

The effectiveness of management accounting can be influenced by the organizational culture. In some cases, organizational cultures may resist or not fully embrace the information and insights provided by management accounting.


9. Inability to Predict External Factors:

Management accounting is limited in its ability to predict external factors such as changes in market conditions, economic trends, or political events. This can make it challenging for organizations to adapt quickly to unexpected changes.


10. Emphasis on Quantifiable Data:

Management accounting tends to emphasize quantifiable data, and certain qualitative factors that are critical to decision-making may not be adequately considered.





QUESTION 1(b)

Q XYZ Ltd, manufactures a component branded "zed" at the rate of 4,000 units per week. Demand for the component is 2,000 units per week while the production set up cost is Sh.50 per batch. The accountant has provided the holding cost per unit per annum as Sh.0.001

Assume a 50-week year.

Required:
(i) Economic Batch Quantity (EBQ) for the company

(ii) Determine the relevant costs for the EBQ in (b) (i) above
A

Solution


(i) Economic Batch Quantity (EBQ) for the company


EBQ
=
2RS

(1 - U / P)Ch

Where:

R = Annual demand = 2000 x 50 = 100,000

S = Set up cost per batch = sh.50

U = Usage rate = 200 units weekly

P = Production = 4000 units weekly

Ch = Annual holding cost = 0.001

EBQ
=
2 * 100,000 * 50

(1 - 2,000 / 4,000)0.001

EBQ
=
10,000,000

0.0005
= 141,421.36 units

(ii) Determine the relevant costs for the EBQ in (b) (i) above


Cost = RS / Q + Q / 2(1 - U / P)Ch

(100,000 / 141,421.36)50 + (141,421.36 / 2)(1 - 2,000 / 4,000)0.001

35.36 + 35.36

Additional information:
1 No provision has been made for Louise Njambi's salary but it is estimated that half of her time will be devoted to the business,
2 She has an option of subletting the stall to a friend at a monthly rent of Sh 5,500 if she does not use the stall herself

Required:
(i) Explain using relevant examples from the situation depicted above: sunk costs and opportunity costs
(ii) Using a cost analysis statement, advise Louise Njambi on whether to live the wall herself or sublet it
A

Solution


(i). Explain using relevant examples from the situation depicted above: sunk costs and opportunity costs


Sunk costs, also known as historical costs, refer to expenses that have already been expended and are therefore not pertinent in decision-making. For instance, a down payment of Sh. 50,000 falls into this category. On the other hand, opportunity cost represents the foregone benefits when a particular course of action is chosen instead of the best alternative. For example, opting to sublet a property for a monthly rental income of Sh. 5,500 and forgoing a net profit of Sh. 130,000 illustrates the concept of opportunity cost.

(ii). Using a cost analysis statement, advise Louise Njambi on whether to live the wall herself or sublet it

QUESTION 2(a)

Q Classification of cost based on function involves classifying costs on the basis of the purpose for which costs are incurred

With reference to the above statement, explain three types of costs classified by function.
A

Solution


Classification of Costs Based on Function


1. Production Costs:


Definition: Production costs, also known as manufacturing costs, are expenses associated with the manufacturing or production of goods or services. These costs are directly tied to the physical creation of products and include both direct and indirect costs.

Components:

  • Direct Materials: The cost of raw materials that can be directly traced to a specific product, such as wood in furniture manufacturing.
  • Direct Labor: The cost of labor directly involved in the production process, including wages and benefits for workers assembling products.
  • Manufacturing Overhead: Indirect costs that are not directly attributable to a specific product but are incurred in the production process, such as factory rent, utilities, and depreciation of manufacturing equipment.


2. Administration Costs:


Definition: Administration costs, also known as general and administrative (G&A) costs, encompass expenses related to the overall management and administration of the entire organization. These costs do not directly contribute to the production of goods or services but are essential for the organization's overall functioning.


Components:

  • Salaries of Administrative Staff: The wages and benefits of employees responsible for general management, finance, human resources, and other administrative functions.
  • Office Supplies: Costs associated with office materials and supplies necessary for day-to-day administrative activities.
  • Utilities and Facility Costs: Expenses related to maintaining and operating office spaces, including rent, utilities, and maintenance.


3. Selling and Distribution Costs:


Definition: Selling and distribution costs are incurred to promote, sell, and deliver products or services to customers. These costs are associated with the marketing and distribution of goods and include expenses aimed at reaching customers and facilitating product delivery.


Components:

  • Sales Commissions: Payments made to sales staff based on the volume or value of products sold.
  • Advertising and Marketing Costs: Expenditures related to advertising campaigns, promotional activities, and marketing materials aimed at increasing product visibility and sales.
  • Distribution Expenses: Costs associated with the transportation, warehousing, and delivery of products to customers, including shipping costs and distribution center expenses.





QUESTION 2(b)

Q The administrator of Chehatok Hills Hospital would like to establish a cost formula linking the administrative costs involved in admitting patients to the number of patients admitted during the month. The admissions department's costs and the number of patients admitted during the last eight months for the year 2017 are given below

Required:
(i) Using the high-low method, estimate the fixed and variable components of admission costs.
(ii) Using the least squares method, estimate the relationship between number of patients admitted and the admission costs in the form of Y = a + bx
(iii) Using the relationship obtained in (b) (ii) above, estimate the admission costs incurred in January 2018 if admission was 2,000 patients
A

Solution


(i) Using high low method to estimate cost


Highest output level 1,900 patients& cost 15,200 lowest output level 1,100 patients and cost 12,800 equation of y = a + bx

Where b = Change in cost / Change in output

( 15,200 - 12,800) / (1,900 - 1,100) = Sh.3

y = a + bx

Where:

y = Total cost
a = Fixed cost
b = Variable cost
x = Output

Assuming output is 1,900 patients then:

15,200 = a + 3 * 1,900

15,200 = a + 5,700

a = 15,200 - 5,700

a = 9,500

y = 9,500 + 3x

(ii) Using simple regression

=
(8 * 175,490,000) - (12,400 * 112,400)

8 * 19,700,000 - 12,400²

10,160,000 / 3,840,000 = 2.646

a = (∑y / n) - (b∑(x / n))

112,400 / 8 - (2.645 * 12,400 / 8)

14,050 - 4099.75 = Sh. 9,950.25

Regression equation

y = 9,950.25 + 2.645x

(iii) Total cost for 2000 patients


y = 9,950.25 + 2.646x

9,950.25 + 2.645 * 2,000

Sh.15,240.25




QUESTION 3(a)

Q Required:

(i) Compute the company's predetermined overhead absorption rate for the year

(ii) Compute under-applied or over-applied overhead cost for the year

(iii) It is the policy of the company to allocate any under or over-applied overheads to cost of goods sold, Determine the cost of goods sold to be charged to the income statement.
A

Solution


(i) Compute the company's predetermined overhead absorption rate for the year


Fixed manufacturing overheads costs / Budget hours

1,275,000 / 85,000 = Sh. 15

(ii) Compute under-applied or over-applied overhead cost for the year


Actual manufacturing overhead costs = Sh.1,350,000

Absorbed manufacturing overheads

= 60,000 x 15 = Sh. 900,000

if applied overhead is greater than actual overhead,then overhead is over = Absorbed overheads - Actual overheads incurred

900,000 - Sh. 1350 000 = Sh. 450,000(Under-applied)

(iii) Cost of sales to be charged in income statement.


Production = Cost of goods sold + closing stock finished + closing stock work in progress

2,800,000 + 1,040,000 + 160,000 = 4,000,000( understated)

Portion of under applied overheads to be added to cost of goods sold

Cost of goods sold / Production Cost x Under Applied Overheads

2,800,000 / 4,000,000 * 450,000 = 315,000

Adjusted cost = Cost of sales + Apportioned under applied overheads

2,800,000 + 315,000 = Sh.3,115,000




QUESTION 3(b)

Q Required:

(i) Production budget for the quarter.

(ii) Direct labour budget.

(iii) Calculate the shortfall in direct labour hours.
A

Solution


(i) Production budget for the quarter.

(ii) Direct labour budget.


Direct labour hours required = Units produced x Labour hours per unit

8,000 × 3 = 24,000 hours

Total hours needed taking into accounting the idle time

100 / 80 × 24000 = 30,000 hours

(iii) Calculate the shortfall in direct labour hours.


1,440 x 18 = 25,920 hours.

Shortfall in direct labour hours
30,000 - 25,920 = 4,080 hours

QUESTION 5(a)

Q Required

Distinguish between "interlocking accounting systems" and "integrated accounting systems" as used in cost bookkeeping
A

Solution


Interlocking Accounting Systems:


Interlocking accounting systems refer to a set of separate and independent accounting systems within an organization. In this approach, various aspects of accounting, such as cost accounting, financial accounting, and management accounting, operate as distinct and standalone systems. Each system has its set of records, procedures, and reports, and there is limited or no integration between them. This lack of integration can lead to potential inefficiencies, as data may need to be manually transferred or reconciled between systems, resulting in the possibility of errors.

Integrated Accounting Systems:


Integrated accounting systems, on the other hand, involve the unification of various accounting functions into a single, cohesive system. In an integrated system, data is shared seamlessly between different modules, including cost accounting, financial accounting, and management accounting. This integration allows for real-time updates and a holistic view of the organization's financial information. Information entered into one module automatically affects other modules, eliminating the need for manual data transfer and reducing the likelihood of errors. Integrated accounting systems promote efficiency, accuracy, and better decision-making by providing a comprehensive and interconnected view of the organization's financial data.

Summar


The key distinction lies in the level of connection between accounting functions. Interlocking accounting systems operate independently, whereas integrated accounting systems bring together various accounting functions into a unified and interconnected system, streamlining processes and improving overall efficiency.




QUESTION 5(b)

Q Highlight two advantages of marginal costing
A

Solution


Marginal Costing


Marginal costing, also known as variable costing, is an accounting technique where only variable manufacturing costs are considered as product costs, and fixed manufacturing costs are treated as period costs.

Advantages of Marginal Costing

1. Simplicity and Ease of Use:


Marginal costing is straightforward and easier to understand compared to absorption costing. It involves fewer complex calculations, making it more accessible for management and decision-makers.


2. Clarity in Decision-Making:


Marginal costing provides a clear distinction between variable and fixed costs. This clarity is particularly beneficial for decision-making, as it helps management focus on the impact of production and sales volume on profitability.


3. Contribution Margin Analysis:


Marginal costing emphasizes the concept of contribution margin, which is the difference between sales and variable costs. This facilitates a quick assessment of the profitability of products or services and aids in making decisions to maximize contribution and overall profit.


4. Flexible Budgeting:


Marginal costing is conducive to flexible budgeting. Since fixed costs are treated as period costs, the budget can be easily adjusted for changes in production levels without the need to allocate fixed costs per unit.


5. Cost-Volume-Profit (CVP) Analysis:


Marginal costing is particularly useful for Cost-Volume-Profit analysis. It allows management to assess the impact of changes in volume on costs and profits, providing insights into break-even points and profitability levels.


6. Effective Pricing Decisions:


Marginal costing helps in making effective pricing decisions. By focusing on variable costs, management can set prices that cover variable costs and contribute towards covering fixed costs, ensuring profitability.


7. Better Inventory Valuation:


Closing inventories are valued at variable production costs in marginal costing. This approach provides a more realistic reflection of the economic value of inventories, especially when production volumes fluctuate.


8. Facilitates Short-Term Decision-Making:


Marginal costing is well-suited for short-term decision-making, as it emphasizes incremental costs and revenues associated with specific decisions. This is valuable for scenarios such as special orders, discontinuation of products, or pricing decisions.


9. Reduces Overhead Absorption Issues:


Unlike absorption costing, marginal costing avoids the complexities associated with overhead absorption rates. Fixed overhead costs are treated as period costs, eliminating the need for arbitrary allocation methods.


10. Performance Evaluation:


Marginal costing aids in performance evaluation by focusing on contribution margins and segmental profitability. This can help identify and prioritize profitable segments within an organization.





QUESTION 5(c)

Q Required:

(i) Materials usage variance.

(ii) Labour rate variance,

(iii) Variable overheads efficiency variance.

(iv) Fixed overheads volume variance
A

Solution


(i) Material usage variance (MUV)


MUV SP(SQ-AQ) Where:
SP → Standard price per kg = Sh 4

SQ → Standard quality for actual output produced
1,800 × 1 = 1800kg

MUV = 4(1800 - 2000) = 4(200) = Sh.800 Adverse

( ii) Labour rate variance (LRV)


(AR) Actual rate = 8.50

Standard rate (SR) = 8

Actual hour (Ah) 480 hours

LRV = (SR - AR)Ah

(8.00 - 8.50)480 = Sh. 240 A

(iii) Variable overhead efficiency variance (VOEV)


Variable overhead efficiency variance

Variable overhead absorption rate (Standard hours - Actual hours)

VOEV = VOAR(SH - AH)

VOAR = Variable overhead cost budgeted / Budgeted hours

48,000 / (24,000 × 0.25) = Sh. 8

VOEV = 8(1,800 x 0.25 - 480)

= 8(450 - 480) = Sh 240 Adverse.

(iv). Fixed overhead volume variance


Fixed overhead volume variance = Fixed overhead Absorption rate per hours (Budgeted hours -Standard hours for actual reduction) Standard hours for actual production

0.25 x 1,800 = 450hrs

Budgeted hours = 0.25 x 2000 = 500 hrs.

Fixed over head absorption rate= 120,000 / (24,000 x 0.25) = Sh 20 per hr

Fixed overhead volume 20(500 - 450) = Sh. 1,000 Adverse
