Managerial Accounting – A
Preamble
1-2
1. Definition of accounting
The process of identifying, measuring and communicating
economic information to permit informed judgements anddecisions by users of the information.
2. Users of accounting information can be divided into
two categories:
(i) external parties outside the organization (financial accounting)
(ii) internal parties within the organization (management/Cost
accounting)

3. Major differences between financial
and management accounting: Statutory requirement for public companies to produce annual financial
accounts, whereas there is no legal requirement for management accounting.
Financial accounting reports describe the whole of the organization, whereas
management accounting focuses on reporting information for different parts of
the business.
Financial accounting reports must be prepared in accordance with generally
accepted accounting principles (e.g. SSAPs).
Financial accounting reports historical information, whereas managementaccounting places greater emphasis on reporting estimated future costs and
revenues.
Management accounting reports are produced at more frequent intervals.

Managerial versus Financial Accounting
Managerial Accounting Financial Accounting
Users of Information Managers, within the organization. Interested parties, outside the organization.
Regulation Not required and unregulated, since it is intended
only for management.
Required and must conform to generally accepted
accounting principles. Regulated by the Financial
Accounting Standards Board, and, to a lesser
degree, the Securities and ExchangeCommission.Source of Data The organization's basic accounting system, plus
various other sources, such as rates of effective
products manufactured, physical quantities of
material and labor used in production, occupancy
rates in hotels and hospitals, and average take-offdela s in airlines.
Almost exclusively drawn from the organization's
basic accounting system, which accumulates
financial information.
Nature of Reports and
Procedures
Reports often focus on subunits within the
organization, such as departments, divisions,
geographical regions, or product lines. Based on a
combination of historical data, estimates, and
projections of future events.
Reports focus on the enterprise in its entirety.
Based almost exclusively on historical transaction
data.

1. Inventory valuation for internal and external profit measurement
Allocate costs between products sold and fully and partly completed
products that are unsold.
2. Provide relevant information to help managers make better decisions

3. Provide information for planning, control and performance
measurement
Long-term and short-term planning (budgeting)
Periodic performance reports for feedback control
Performance reports also widely used to evaluate managerial
performance
Note that costs should be assembled in different ways to meet the
above three requirements.

Those labor costs that can be easily traced toindividual units of product.

Manufacturing costs that cannot be traced directlyto specific units produced.
Manufacturing Overhead
Examples: Indirect labor and indirect materials
Wages paid to employees whoare not directly involved in
production work.Examples: maintenance
workers, janitors and securityguards.
Materials used to support theproduction process.
Examples: lubricants andcleaning supplies used in theautomobile assembly plant.

Every decision involves a choice between at least
two alternatives.
Only those costs and benefits that differ between
alternatives are relevant in a decision. All other
costs and benefits can and should be ignored.

Differential Cost and Revenue
Costs and revenues that differ amongalternatives.
Example: You have a job paying $1,500 per month in yourhometown. You have a job offer in a neighboring city that
pays $2,000 per month. The commuting cost to the city is
$300 per month.
Differential revenue is: $2,000 – $1,500 = $500
Differential cost is:

Opportunity Cost

Opportunity Cost
The potential benefitthat is given up when
one alternative isselected over another.
Example: If you were
not attending college,
you could be earning
$15,000 per year.Your opportunity cost
of attending college for
one year is $15,000.

Sunk Costs
Sunk costs have already been incurred andcannot be changed now or in the future.They should be ignored when making
decisions.Example: You bought an automobile that cost $10,000two years ago. The $10,000 cost is sunk because whether
you drive it, park it, trade it, or sell it, you cannot change
the $10,000 cost.

Distribution of Quality Costs
When quality of conformance is low, total quality
cost is high and consists mostly of internal andexternal failure.
Total quality costs drop rapidly as the quality of
conformance increases.
Companies reduce their total quality costs by
focusing their efforts on prevention and
appraisal because the cost savings from
reduced defects usually overwhelm the costs of
additional prevention and appraisal.
Total quality costs are minimized when the quality
of conformance is slightly less than 100%.
