QUESTION 1(a)

Q Explain the following terms as used in management accounting

(i) Opportunity cost.

(ii) Notional cost

(iii) Discretionary cost

(iv) Incremental cost.
A

Solution


(i) Opportunity Cost:


Definition: Opportunity cost refers to the value of the next best alternative forgone when a decision is made to allocate resources (such as time, money, or effort) to a particular option.

Example: If a business has the option to invest its funds in Project A or Project B, and it chooses Project A, the opportunity cost would be the potential benefits or profits that could have been gained from Project B.


(ii) Notional Cost:


Definition: Notional cost is a cost that is calculated or recorded for accounting purposes, even though it may not involve an actual cash outlay. It is a theoretical or bookkeeping cost.

Example: Amortization of goodwill or depreciation of a non-depreciable asset might be considered notional costs. These costs help in allocating the value of an asset over time, even if there is no direct cash payment associated with it.


(iii) Discretionary Cost:


Definition: Discretionary costs are costs that arise from periodic, rather than regular, decisions by management. These costs can be adjusted or eliminated by management to meet changing business needs.

Example: Costs related to advertising, employee training, or research and development are often discretionary. Management has the discretion to increase, decrease, or eliminate these costs based on the company's short-term or long-term objectives.


(iv) Incremental Cost:


Definition: Incremental cost, also known as differential cost, represents the additional cost incurred or saved when making a decision between two alternatives. It focuses on the change in costs resulting from choosing one option over another.

Example: If a company is deciding whether to introduce a new product, the incremental cost would include the additional expenses associated with producing and marketing that specific product compared to not producing it. It helps in evaluating the financial impact of the decision.





QUESTION 1(b)

Q (i) Using the high-low method, derive a predictor equation in the form of Y = a + bx for the company

(ii) Determine the total cost that would be incurred tis produce 8,500 units of the product
A

Solution


(i) Using the high-low method, derive a predictor equation in the form of Y = a + bx for the company

y = a + bx

b = (173,260 - 165,772) / (8,750 - 8,100) = 11.52

a = y - bx

a = 165,772 - 8,100(11.52)

a = 72,460

y = 72,460 + 11.52x

(ii) Determine the total cost that would be incurred tis produce 8,500 units of the product

y = 72,460 + 11.52(8,500)

y = Sh.170,380




QUESTION 1(c)

Q (i) The current shortfall in highly skilled labour at maximum demand.

(ii) The optimal production mix.

(iii) The resultant profit at the optimal production mix.
A

Solution


(i) The current shortfall in highly skilled labour at maximum demand.


Limiting factors

A = 24 / 8 x 2,000
B = 32 / 8 x 3,000
C = 44 / 8 x 1,800

= 6000hrs
= 12000hrs
= 9900hrs
27900hrs


Shortfall = 27900 - 25000 = 2900hrs

(ii) The optimal production mix.

QUESTION 3(a)

Q Describe the three main stages of the Activity Based Costing (ABC) system.
A

Solution


Three Main Stages of Activity-Based Costing (ABC) System:


Activity-Based Costing (ABC) is a costing methodology that identifies activities within an organization and assigns costs to these activities based on their consumption of resources. The ABC system typically involves three main stages:

1. Activity Identification:


In this initial stage, various activities within the organization are identified. These activities are categorized into primary activities directly involved in production and secondary activities that provide support.


2. Activity Measurement:


Once identified, activities are measured in terms of resource consumption. Data is collected through methods such as interviews or time studies to determine cost drivers, which are factors correlated with the consumption of resources by each activity.


3. Cost Assignment:


After identifying and measuring activities, costs are assigned to products or services based on the determined cost drivers. This allows for a more accurate allocation of costs, providing a realistic representation of the cost structure and enabling better decision-making.

Q Calculate the charge for overhead to each of the three production cost centres, including the amounts reapportioned from the two service centres using:

(i) The continuous allotment (repeated distribution) method.

(ii) The algebraic method.

Let x be total overhead of material handling

Let y be total overhead of inspection

X = 100 + 0.05 and

y = 50 + 0.1x

X = 100 + 0.05(50 + 0.1x)

X = 100 + 2.5 + 0.005x

0.995X / 0.995 = 102.5 / 0.995

X = 103.0151

Y = 50 + 0.1(103.0151)

Y = 60.3015
