Module 16- New Developments in Management Accounting
16.1 Introduction
- Increasingly companies are seeking to be more customer driven and have a quicker response to the market
- Management accounting will have to change to reflect these new business paradigms
- The shortcomings of traditional management accounting
- They are still been driven by profit measurement and therefore by inventory valuation
- Direct labor remains a popular method of overhead allocation, even though direct labor as a percentage of product cost is shrinking
- Automated production lines have rendered the concept of fixed and variable costs obsolete
- Traditionally overhead has been seen as a burden but as more companies differentiate on quality of service, increasing overheads has become almost a goal
- the sheer complexity of business has increased exponentially – e.g products can be customized easily using CAD
- Global competitive markets accentuate these problems – the demand for more accurate product costs is increasing
16.2 Target Costing
- Up to now we have assumed that the customer is willing to purchase a product at a price which reflects the costs of production, distribution and a contribution to profit – this is naive
- What do we do when the maximum selling price is well known and perhaps is below the internally calculated costs?
- Target Costing is used when the selling price is known – e.g. a product in an extremely competitive market like the TV market
- Once the target price is known, the desired profit margin can be deducted in order to determine the target cost beyond which the company would consider it uneconomic to produce and sell the product
- Standard costs differ from Target costs in that they are set only when the output is stable and the detailed product specification is known and is unlikely to change
- Target costs start as global figures and are set for an entirely new process
- Target costs are usually lower than existing product costs and so a company must use Value Engineering to streamline its whole product process
- Target costs are market focused – how much will the market pay for this and do they want it?
- Costs are often saved in the design phase, e.g. fewer components usually means lower cost
- Target costing involves a detailed examination of both direct costs involved in production (labor, materials etc.) and the overheads involved in the design, manufacture and distribution
Case Study
Puff sells 100,000 models of its ABX airbag to two car manufacturers who have asked for a 10% price reduction next year. Selling price = $100.
Currently each airbag costs $63 to manufacture, ie. $6.3M per year

Each airbag contains ten components, each from a separate supplier. Currently 30 orders are placed per year with each supplier. Currently 50% of the airbags fail the test, which take two hours, and are then subject to recalibration.
Financial Controller: We need to reduce costs by $10/unit to maintain our current profit margin
R&D Manager: We can reduce the number of components from 10 to 8
Purchasing: We can drop the number of orders placed from 30 to 25. We can cut material cost per bag by $6 and direct labor to $1 less per bag
Chemical & Explosive Manager: We can reduce the number of hours it takes to test a bag from 2 hours to 1.75
Recalibration: Reducing components will reduce failure rate to 10%
Ans:
Savings
Direct Material$6 x 100,000$600,000
Direct Labor$1 x 100,000$100,000
Machine CostsNo change
R&D costsNo change
Chemical & Explosive test0.25 x $3.50x 100,000$87500
Recalibration40% x 100,000 x $18.66$764,400
Ordering and Faciltating((10x30) – (8x25)) x $224$24,000
$903,200
New cost total = $6,300,000 - $903,200 = $5,396,800
To drop our price to $53 => $53 x 100,000 = $5,300,000
- Target not reached, perhaps look at why R&D and machine cost are fixed, e.g. machine costs should fall as number of components falls
- R&D could be outsourced, resulting in short term savings
16.3 Life Cycle Costing
- Life cycle costing does not stop at the usual annual accounting end of year, like investment appraisal it goes from the conception of a product to the moment the product is withdrawn and all services supporting that product cease
- Life cycle costing gathers all cost and revenues of the entire life of a product so that its ultimate profitability can be measured
- Conventional management accounting, because its annual-driven, tends to miss the upfront costs of product design, launch etc.

- ABCost is the most profitable
- However before going with ABCost the firm may want to take a look at cutting costs for the other two since they have higher price and more market penetration
- Taxplan suffer because it has ongoing support costs even after the product is removed from the shelves
- Perhaps an over the wire upgrade
- Life Cycle costing is often used with target costing – particularly with products that have a long life expectancy
16.4 Throughput Accounting
- Today business are under pressure to reduce the response times between company and customer, and also to reduce inventory of both raw and finished goods (JIT)
- Does the traditional methods of costing allow us to make fullest use of the latest technologies?
- Throughput is defined as the rate at which money is earned
Scenario One
- Plant supervisor under pressure to avoid having adverse cost variances this quarter
- He must choose between two manufacturing alternatives
- Alternative A uses a new machine with a low labor input, accountant views the high depreciation charge on this item as a production overhead to be loaded according to direct labor hours => less overhead because labor costs are low
- Alternative B – use an older machine to do the task, this has a lower depreciation charge and so the supervisor likes this option as well
Throughput version of this Scenario
- Fixed costs, like depreciation, should be excluded from performance measurement
- Total factory costs – those which over the short term do not change with production – should be grouped together as one cost
- An example of a total factory cost is direct labor – which has to be employed in the short term whether or not they are producing anything
- Only material costs are excluded from total factory costs
Scenario Two
- Supervisor is concerned at the idle time in his labor variances due to machine not been run all the time
- He wants to fill this time by increasing production full capacity and filling inventory full of finished goods
- So he can avoid questions about poor variances, while adding value to materials
Throughput version of Scenario Two
- Value is added to a company not what products are made but when they are sold
- This is contrary to the traditional financial view that rewards high closing inventory with a high profit figure
- It is cheaper for a company to absorb total factory costs than total factory costs plus a build up of unwanted inventory
- Inventory should be driven down (JIT)
Scenario Three
- Two products have exactly the same cost structure but just differ in labor costs – X costs $100/unit in direct labor, Y costs $105/unit
- Y takes 10.5 hours , X takes 10 hours
- There is a bottleneck at machining, where of an available 200 hours per week, X takes up 4 while Y only 2
- The manager decides that X is more profitable of the two because of the cheaper direct labor costs
Throughput version of Scenario 4
- In throughput, profitability is defined as the rate at which cash is received from customers
- Product Y can be produced at twice the rate of Product X at the bottleneck and so Y should be favored
- The throughput ratio is calculated using return per factory hour and cost per factory hour:
Return per factory hour = Sales price – Material Cost
Time spent at the factory bottleneck per product
Cost per factory hour = Total Factory Cost
Total time at factory bottleneck
- These two numbers are then combined to give a throughput accounting ratio
Throughput accounting ratio = Return per factory hour
Cost per factory hour
This is the rate at which products earn money for the business
Example
For products X and Y :
Selling price per unit$200
Direct Material per unit$50
Total Factory Cost$8000
Again, time at the bottleneck : X = 4 hours, Y = 2
X: Return per factory hour = 200-50/4 = $37.50/hour
Y: Return per factory hour = 200-50/2 = $75/hour
X: Cost per factory hour = 8000/200=$40
Y: Cost per factory hour = 8000/200=$40
X: Throughput Accounting Ratio = $37.50/$40 = 0.9375
Y: Throughput Accounting Ratio = $75/$40 = 1.875
- Product Y shows the ability to generate more money in sales than is spent on production (Throughput Accounting Ratio > 1), X doesn’t
16.5 Costing for Competitive Advantage
- Accountants are becoming more involved in strategic discussions and decisions – they often are able to rise above the feuds and vested interest
- Management accountants can be involved in production planning - in this subject a number of issues are considered:
-production facilities
-labor skills
-sourcing of supplies
-introduction of JIT and total quality inspection
-the decision whether to make or buy specific components
-suppliers’ ability to cope with peak in demand
- Production strategy could be expressed in on of the following terms of:
-% increase in output
-decrease in rejects
-buy in components
- Management accounting can help in quantifying the various strategies under review
Example
Electric motor is a supplier of electric motors two white goods companies. Each say they need to 2100 motors between them per month an can guarantee that level for 12 months. Selling price is $80.
The limiting factor is supply of skilled machinists – availability is limited to 4500 hours/month. Electric Motor has used a subcontractor at peak demand time.
Option 1: Electric Motor should manufacture as many motors as it can and subcontract the balance to Sparks – Electric Motor would still have to test the motors - $3 per motor.
Option 2: Electric Motor should manufacture as many of the three separate components as it can and subcontract the remaining components to Sparks. Electric Motors would assemble and test [ignore assembly costs]

1 Contribution comes from selling its motors externally & manufacturing components internally
- Option 2 gives marginally more profit and so is preferred
- The small difference may not be worth the effort of cheery picking components

Case Study 16.1
Selling price = $200
60 components
unit production cost = $115, so old margin = 95
Sales units 5000
New selling price $180, so new production cost/unit = $95 => $475,000
savings in direct materials $15 x 5000 = 75000
increase in RD(10000)
savings in direct labor 10% of 800008000
machining costs2000
savings in purchasing2000
savings in testing10,000
$87,000
so new production costs = 488, not enough of a reduction
