AC206 Flashcards
When does information become decision relevant?
- Objectivity: should adequately represent the status quo, i.e. mirror the economic reality of the organisation.
- Strategy: information shouldn’t only represent the status quo but also future related strategic aspects and how those will be affected by any managerial decisions
- Balance: info should be manageable and comprehensive i.e. there has to be a balance between too much and too little information
- Robustness: info should mean the same in different contexts and shouldn’t be subject to high fluctuation risks.
- Timeliness: info should be quickly accessible by a variety of actors across the organisation.
Relevant costs & revenues
- future costs/revenues that will be impacted by a decision
- change depending on which option is chosen
Irrelevant costs & revenues
- past costs (already spent) e.g. sunk costs
- unchanged (indifferent) by any decision
Cause and effect relationships
- physical link: a direct connection between a cost and what causes it (tyres on cars)
- contractual agreement: costs that arise based on contracts and agreements (data traffic provided/delivery cost)
- operational logic: using knowledge of how things work to understand why certain costs happen (testing theories via statistical analysis - shows correlation)
Types of errors in costing systems design
- specification error (choosing the wrong cost driver)
- selected cost driver has no real cause-effect relationship with overhead costs.
- the chosen base doesn’t actually reflect what drives the cost. - aggregation error (combining cost pools)
- resources are grouped incorrectly, using a single allocation rate for different activities
- similar but different costs are incorrectly “added together” under one rate - measurement error (measuring cost pools/drivers incorrectly)
- miscalculating the costs in a pool or the amount of activities used by each product
less refined (low fineness)
pros: inexpensive to implement
cons: uses arbitary cost allocations; prone to serious errors or distortion in data.
more refined (high fineness)
pros: costs are allocated based on clear cause-effect relationship; results in fewer errors or distortions
cons: expensive to set up and maintain key considerations
Why isn’t accuracy in costing systems always needed?
managers may add biases to cost data to influence behaviour rather than just to inform decisions. These are called “behaviourally-orientated cost systems”
Examples of bias in costing systems: upward bias
sales managers may lower prices too much or offer exessive discounts to meet revenue targets
solution: overstate product costs to prevent underpricing
Examples of bias in costing systems: downward bias
firms use target costing to set goals below current standards or push innovation
costs are understated to create unfavourable variances, signalling the need for improvement
Examples of bias in costing systems: low sophistication
firms use fewer cost pools to focus on key cost drivers, like the number of parts in a product design.
some costs may be misallocated, but the focus on simplifying design helps long term competitiveness.
What is an activity measure?
An activity measure is a quantitative indicator of how much work or action is performed. It represents the level of an activity, such as the number of units produced or hours worked, and is used in cost analysis to evaluate performance.
What is a cost driver?
A cost driver is a factor that causes a change in the total cost of an activity. It directly influences the cost incurred in producing goods or services, such as labor hours, machine usage, or number of units produced.
What is a true cost driver?
A true cost driver is a factor that accurately and directly causes costs to change. It has a direct cause-and-effect relationship with the cost, meaning that when the cost driver changes, the associated cost also changes proportionally.
What is the relevant range?
The relevant range refers to the range of activity levels within which the assumptions about cost behavior hold true. Within this range, fixed costs remain constant, and variable costs per unit stay the same, but outside this range, cost relationships may change.
What are fixed costs?
Fixed costs are expenses that do not change with the level of activity or production. These costs are incurred regardless of the volume of goods or services produced, such as rent, salaries, or depreciation.
What are variable costs?
Variable costs are expenses that change in direct proportion to the level of activity or production. As production increases, variable costs increase, and as production decreases, variable costs decrease, such as raw materials and direct labor.
What are direct costs?
Direct costs are expenses that can be directly attributed to a specific cost object, such as a product, department, or project. Examples include the cost of raw materials used in manufacturing a product or wages paid to employees working on a specific project.
What are indirect costs?
Indirect costs are expenses that cannot be directly traced to a specific cost object. These costs are shared across multiple products or departments and require allocation, such as utilities, rent, and administrative salaries.
What are flexible costs?
Flexible costs are costs that can be adjusted based on the level of activity or demand. These costs are incurred only when needed and can be increased or decreased depending on production or operational requirements, such as raw material orders.
What are committed costs?
Committed costs are long-term, fixed expenses that a company has agreed to pay in advance, regardless of current levels of activity. These costs are difficult to change in the short term, such as long-term lease agreements or capital investments.
What is cost traceability?
Cost traceability refers to the ability to directly associate a cost with a specific cost object, such as a product, service, or department. It determines whether a cost is direct (easily traced) or indirect (requires allocation).
What is a unit cost?
A unit cost is the total cost incurred to produce one unit of output. It is calculated by dividing the total costs (both fixed and variable) by the number of units produced.
What is cost behavior?
Cost behavior refers to how costs change in response to changes in the level of activity or production. Costs can be classified as fixed, variable, or mixed, depending on how they react to increases or decreases in activity levels.
