MANAGEMENT ACCOUNTING AND
Custom Design Pty Ltd makes custom-order curtains and soft furnishings . In
June 2013 when managers prepared the budget for the 2014 year, they estimated Mfg Oh would total $100,000. As the process is labour intensive, OH is allocated to jobs based on DLH and 400,0000 total DLH were expected.
During September and October 2013, employees worked on only 3 jobs.
Relevant information for each follows:

Cost System Design
Service Department allocation
Over-costing; under-costing (product cost cross-subsidisation)
Summary: Reasons for refining and guidelines for refining
Understand what is meant by ‘capacity’ concepts for fixed overhead
It is assigning indirect costs to cost objects
Indirect costs are not traced due to relative cost vs benefit 5
As a result, an inaccurate allocation can have significant costs to an organisation
Does “What is the information used for” matter?
Raises question as to the accuracy of cost (& allocation)?
Indirect costs often comprise a large percentage of total costs in contemporary environment
Use? Factors that impact cost system design? o Traditional Costing
Develop and apply principles of cost allocation and refinement Demonstrate the 2 stage allocation process
Absorption costing vs variable costing; allocate Fixed OH or not? Capacity concepts for fixed overhead allocation under normal and standard costing systems; a strategic management decision
2 stage allocation using ‘volume’ bases
Explain how broad averaging of indirect costs can result in under-costing and over-costing of products and services
Explain how choice of allocation bases can impact accuracy and decisions
Understand how an existing costing system when analysed in light of a firm’s characteristics including its competitive position, output and processes; impacts on management decision making (and behaviour) and ultimately firm
Identify the different purposes of cost allocation
Explain the difference between variable and absorption costing

LECTURE – OVERVIEW
Cost accounting purpose
LEARNING OBJECTIVES – L 3
Criteria for cost allocation
1) What was the budgeted (predetermined) overhead rate for 2014?
2) Calculate the cost of each job (using data provided) at the end of (i) September (ii) October .
3) What was the WIP balance on Sept 30? Oct 31?
4) What was the COGM for September? October?
5) What was the COGS for October?
Job 76 was started in Sept and finished and delivered to the customer in Oct.
Job 77 was started in October, finished in October and delivered to the customer in November. Job 78 was started in Oct and finished in November.

Different costs for different purposes!
Increase accuracy by ‘refining’
Issues when refining:
Number of indirect cost pools?
Appropriate cost allocation base(s)?
PURPOSES OF COST ALLOCATION
CRITERIA FOR COST-ALLOCATION
Four purposes of cost allocation:
