ABSTRACT
Decision making has become a main concern to any organization and efforts are being made by management to make sure that best decisions are made. Therefore this study investigates the effectiveness and efficiency of marginal costing as an essential tool of decision making.
To determine this, the fundamental objectives of the study among others are:
(a) An evaluation of the marginal costing technique towards ascertaining the effectiveness and efficiency.
(b) Finding out any inherent deficiencies in its application.
(c) To determine the criteria for cost control and analysis
(d) How products decisions are made by management under this technique
(e) And how management decision making is aided under the technique
In investigating the above data were obtained through questionnaire administered to management staff and few senior staff who have knowledge about the technique under application.
Moreso, useful pieces of information were got from libraries. The collected data were classified analyzed and interpreted by tabular discussion and simple percentage analysis and the hypothesis were tested by using the chi-square method. From the analysis of data, the major findings were that:
ANAMMCO apply marginal costing techniques in valuation of stock, cost planning and control.
(a) The company purposefully uses this technique for the following reasons:
i. Decision making
ii. Controlling of cost
iii. Fixing of prices
(b) ANAMMCO uses marginal costing because it is simple to operate.
(c) ANAMMCO uses marginal costing technique because it shows a meaningful and more realistic profit position of the company.
(d) The technique easily reveals the contribution made by each product or department.
(e) That when faced with decision about the best alternative the marginal costing technique is applied.
(f) When there is a special order in deciding whether to accept or reject the special order, marginal costing technique is used.
Based on the findings the following recommendation were made:
(a) The organization should find a way of ensuring that instrumentality is closely tied to productivity or output of the employee.
(b) Due to the difficulty associated were receipt of orders, the orders for basic raw materials should be made long in advance.
(c) Where there is a request for special ore,r marginal costing should be applied.
(d) The company budgetary control system should be supported with the standard costing technique for effective control of materials and labour cost.
Above all, I strongly believe that if those recommendations are accepted and vigorously pursued, the decision making will meet the set organizational objectives.

CHAPTER ONE
10 INTRODUCTION
11 BACKGROUND OF STUDY
The reality of modern business management in a free enterprises economic system in the level of competition among all enterprises where only the fittest enterprise survive The motive for maximization of profit in business and quest for wealth creation being in Hogue, management continues to remain under increasing obligation to improve its share of market, its assets, its credit worldliness and its overall potential
These in turn require an improvement in the quality of decision therefore in order to responds effectively to the challenges of time, management requires good factors in business decisions The research work is a real attempt to investigate into the principle and practice of marginal costing as an essential tool for decision making in manufacturing companies using Anambra Motor Manufacturing Companies (ANAMMCO) as a case study The study will critically examine the following:-
- The condition for analyzing cost into fixed and variable components
- How the cost are normally controlled
- And how management decision is ended under the techniques
An appraisal is necessary in order to determine effectiveness and efficiency of the management accounting technique In carrying out this research work, data was gotten from questionnaire, information and analysis of data using the percentage method to analyze the responses elicited from respondents Also the personal observation method were used together with relevant information from libraries
BRIEF HISTORY OF ANAMMCO
Against the background of rapid economic growth, the federal military government in 1975 was faced with the enormous task of developing the country's infrastructure from one geared towards farming to one oriented towards mechanized agriculture and industry
The Anambra Motor Manufacturing Company is the result of the economic and technological co-operation between the government and the people of Nigeria and DAIMLER - BENZ of the West Germany
The company is located at Emene Industrial Layout Enugu The site covers an area measuring over 300,000 square meter generously leased by the state government
Although the partnership agreement was signed in 1975 The company was incorporated in Nigeria on the 19th of January 1977 under the name of Anambra Motor Manufacturing Company, as a private limited liability company with an authorized share capital of N7,000,000 ordinary share of N100 each all of which were issued and fully paid up
SHARE HOLDING
The share holding is as follows
DIAMLER BEN AG OF GERMANY - 4000
FEDERAL GOVERNMENT OF NIGERIA - 3500
ANAMBRA STATE GOVERNMENT - 120
IMO STATE GOVERNMENT - 40
RIVER STATE GOVERNMENT - 30
NIGERIA CITIZENS & ASSOCIATES - 60
10000
Despite the fact that the company was incorporated in 1977, the laying of foundation stone was done on 12th of May 1978 by the military governor of the old Anambra state, Col John Atomkpeta The official commissioning of the plant was done on July 8th 1980 by the president of the federal republic of Nigeria
12 STATEMENT OF PROBLEMS
In this study, we are to answer the question listed below:
a Can marginal costing restrict the arbitrary allocation of production cost on cost centered?
b With this technique applied in costing, can production not be increased hence increasing the amount of fixed cost in the production?
c When management is engaged with 2 or more alternatives, would marginal costing be a useful tool for selection or choosing the best alternatives?
13 OBJECTIVES OF STUDY
Marginal costing as an essential tool for decision making Marginal costing technique of cost accounting tends to separate cost into variables and fixed components Bearing this in mind, the objectives of this study among other things include:
- An evaluation of the marginal costing technique towards ascertaining its effectiveness and efficiency
- Finding out any inherent deficiencies in its application
- To determine the condition for cost control and analysis
- Examine how product decisions are made by management under this technique
14 SIGNIFICANCE OF THE STUDY
Since it is a technique of cost accounting adopted by an organization to measure its profit ability, any effort geared towards establishing how the technique helps in the profit realization of the organization is worth slide
Since this relationship is reciprocal, any suggestion on the improvement of the costing technique should have some bearing on profit improvement If output or productivity is to be enhanced and profit maximized, a knowledge of cost behaviour and analysis into the various components is essential and worth understanding
Based on the findings of the study and the suggestion proffered, it is strongly hoped that the profit will improve
15 SCOPE OF THE STUDY
This study is limited to the survey of how the marginal costing technique is used to make decision at the Anambra Motor Manufacturing Company (ANAMMCO) and how effective and efficient it is to the company This investigation is not to be taken as an exhaustive piece
16 LIMITATION OF THE STUDY
This researcher had difficulties in collecting all the relevant data required for an in depth evaluation of this subject This constraints emanated from the fact that the company (ANAMMCO) is said to be a competitive manufacturing company concern and the general manager considers it risky to issue out information required
17 DEFINITION OF TERMS
Manufacturing industry: A manufacturing industry is one that acquires raw materials and intermediate goods and transfer them to finished goods through an industrial process The definition satisfies the purpose of the study A manufacturing industry can also be defined as one where pre-occupation is the processing of materials into other goods through the use of labour and factory facilities
Marginal cost: Marginal cost is the amount at any given volume of output by which aggregate costs are changed of the volume of output is increased or decreased by one unit
The marginal cost of a product is alternatively known as its variable cost, which includes direct material, direct labour and direct expenses and the variable part of overheads
Marginal costing: Marginal costing is defined by CIMA's official terminology as "a principle whereby variables cost are changed to cost units and fixed cost attributable to the relevant periods is written off in full against the contribution in that period"
Fixed cost: Fixed cost is a cost that accrues in relation to the passage of time and which, within certain output and turnover limits, tends to be unaffected by fluctuations in the level of activity It is treated as periodic cost and are changed in full to the profit and loss account of the accounting period which they are incurred
Contribution: Contribution is the different between sales value and the variable cost of those sales expressed either in absolute terms or as a contribution per unit This is the central point in marginal costing When the contribution per unit is expressed as the difference between the selling price and its marginal cost Marginal costing cannot be used without calculating the contribution
18 HYPOTHESIS
The following hypothesis are proposed for this study:
i Marginal costing principles aid prudent management decision making
ii Statement prepared using marginal costing principles are easier to understand by management
iii Marginal costing aid in the achievement of the organization goal
