Treatment in accounts Normal loss : The cost of normal loss is absorbed by units
produced.
When normal loss has a scrap value, the same is credited inthe process account.Abnormal gain
Abnormal gain does not affect cost of normal production.
The process account is debited with full cost of abnormal gain. The abnormal gain account is debited and normal process loss
account is credited.
The balance is transferred to costing Profit and Loss account as
abnormal gain.
Cost per unit
The total cost is deducted by normal loss scrap value and then it is
divided by the input units minus the normal loss units.

Abnormal loss Abnormal loss is charged to the respective cost of production.
The process account is credited by abnormal loss account with cost of
materials, labours and overheads equivalent to good units. Abnormal loss units rank equal with normal units.
Abnormal loss account is credited by realizable scrap value and thebalance is written off to costing Profit and Loss Account as abnormalloss.

A managerial accountants
budgetary-control system has three
parts.
First, a predetermined or standard cost is
set. In essence, a standard cost is a
budget for the production of one unit of
product or service. It serves as the
benchmark in the budgetary-control
system. When the firm produces morethan one unit, the managerial accountant
uses the standard unit cost to determine
the budgeted cost of production or the
total standard cost.
Second, the managerial accountant measures the actual cost incurred in the
production process.
Third, the managerial accountant compares the actual cost with the budgeted or
standard cost.
Any difference between the two is called a cost variance. Cost variances then are used
in controlling costs

Managers do not have time to investigate everyvariance between actual and standard costs.
They focus their attention on the causes of significantcost variances.
This is called management by exception.
When operations are going along as planned, actual
costs and profit will typically be close to the budgetedamounts.
However, if there are significant departures fromplanned operations, such effects will show up assignificant cost variances.
Managers investigate these variances to determinetheir causes, if possible, and take corrective actionwhen indicated.
-

Management by Exception (MBE) is a practice where onlysignificant deviations from a budget or plan are brought to theattention of management.
The idea behind it is that management's attention will be focusedonly on those areas in need of action.
When they are notified of a variance, they can hone in on thatspecific issue and let staff handle everything else.
If nothing is brought up, then management can assume everythingis going according to plan.
This model is similar to the vital signs monitoring systems in
hospital critical care units.
When one of the patient's vital signs goes outside the rangeprogrammed into the machine, an alarm sounds and staff runs to the
rescue.
If the machine is quiet, it's assumed that the patient is stable, and
they will receive only regular staff attention.

MBE can bring forward business errors and oversights,
ineffective strategies that need to be improved, changes in
competition and business opportunities.
MBE is intended to reduce the managerial load and enable
managers to spend their time more effectively in areas where
it will have the most impact.

13/43
Two methods are typically used for setting coststandards: analysis of historical data and task analysis.
One indicator of future costs is historical cost data. In a
mature production process, where the firm has a lot ofproduction experience, historical costs can provide agood basis for predicting future costs.
In using task analysis, the emphasis shifts from what
the product did cost in the past to what it should costin the future.
The managerial accountant typically works withengineers to conduct studies in an effort to determine
exactly how much direct material should be required,how machinery should be used in the productionprocess, and many direct labor hours are required.
-

Accountants, engineers, personnel administrators,and production managers combine efforts to set
standards based on experience and expectations.
Participation in Setting Standards
10-14
Standards should not be determined by the managerial accountant alone. People generally
will be more committed to meeting standards if they are allowed to participate in settingthem.
For example, production supervisors should have a role in setting production cost
standards, and sales managers should be involved in setting targets for sales prices and
volume.
In addition, knowledgeable staff personnel should participate in the standard-setting
process.

Perfection versus Practical Standards: A

Should we usepractical standards
or perfection

Practical standards
should be set at levels
that are currently
attainable with
reasonable and

Standards that are as tight as practical, butstill are expected to be attained, are calledpractical (or attainable) standards.
Such standards assume a production processthat is as efficient as practical under normaloperating conditions.
Practical standards allow for such occurrencesas occasional machine breakdowns andnormal amounts of raw-material waste.

I agree. Perfection
standardsare
unattainable and therefore
discouraging to mostemployees.
Perfection versus Practical Standards: A
Behavioral Issue
10-17
Some managers believe that perfectionstandards motivate employees to achieve
the lowest cost possible.
They claim that since the standard is
theoretically attainable, employees will
have an incentive to come as close as
possible to achieving it.Other managers and many behavioral
scientists disagree.
They feel that perfection standards
discourage employees, since they are so
unlikely to be attained.
Moreover, setting unrealistically difficultstandards may encourage employees to
sacrifice product quality to achieve lower
costs.

Use of Standards by Service Organizations
Standard cost analysismay be used in any
organization withrepetitive tasks.
A relationship betweentasks and output
measures must beestablished.
10-18
Many service industry firms, nonprofit
organizations, and governmental units
make use of standards.Fast food restaurants set a standard for the
amount of ingredients in a menu item.
Airlinesset standards for fuel and
maintenance costs.
Insurance companies set standards for the
amount of time to process an insuranceapplication.
Even a district motor vehicle office may
have a standard for the number of days
required to process and return an
application for vehicle registration.
These and similar organizations usestandards in budgeting and cost control in
much the same way that manufacturers
use standards.

There are two types of standard costvariances: price variance and quantityvariance.
A price variance arises when there is adifference between the actual price and thestandard price.
A quantity variance occurs when there is adifference between the actual quantity usedand the standard quantity to be used.

The standard price of $4.00 is subtracted from the actual price of $3.90.
This difference is multiplied by the actual quantity of 1,700 pounds.
The resulting variance is a negative $170.
The variance is favorable because the actual price per pound was less than the standard
price per pound.

Hanson purchased and used1,700 pounds. How are thevariances computed if the
amount purchased differsfromthe amount used?
Zippy
10-37
When the amount of direct-materials purchased is different from the amount
used, the direct-material price variance is based on the quantity purchased.
The difference between the purchase price and the standard price are
highlighted by the price variance, which relates to thepurchasing function.
In contrast, the direct-material quantity variance is based on the amount ofmaterial used in production.
The quantity variance highlights differences between the quantity of material
actually used and the standard quantity allowed.

The standard price of $4.00 is subtracted fromthe actual price of $3.90.
This difference is multiplied by the amount ofmaterials purchases, which is 2,800 pounds.
The resulting direct-material price variance is anegative $280.
The variance is favorable because the actual priceper pound was less than the standard price perpound.
But the variance is larger when a greater quantityof materials were purchased.
