General Accounting General Accounting: Preparation of financial statements for a firm.

General Accounting

General Accounting:
Preparation of financial statements for a firm. A financial statement (or financial

report) is a formal record of financial activities of a business, person, or other entity
Cost Accounting:
A branch of general accounting that deals with the measurement of costs
Depreciation Accounting:
A branch of general accounting that deals with capital assets depreciation

General Accounting Balance sheet: Static picture of assets, liabilities and net

General Accounting

Balance sheet:
Static picture of assets, liabilities and net worth at

a single point in time or a summary of financial balances of a corporation
Assets, liabilities and ownership equity (or shareholder’s equity = initial amount of money invested into a business) are listed as of a specific date, such as the end of its financial year. A balance sheet is often described as a "snapshot of a company's financial condition"
Слайд 5

It is comprised of the following 3 elements:

Assets: Something a business owns

or controls (e.g. cash, inventory, plant and machinery, etc.)
Liabilities: Something a business owes to someone (e.g. creditors, bank loans, etc.)
Equity: What the business owes to its owners. This represents the amount of capital that remains in the business after its assets are used to pay off its outstanding liabilities. Equity therefore represents the difference between the assets and liabilities.

General Accounting Profit and loss statement: Also called “income statement” Income

General Accounting
Profit and loss statement:
Also called “income statement”
Income Statement reports the

company's financial performance in terms of net profit or loss over a specified period.
Слайд 8

Income Statement Income Statement is composed of the following two elements:

Income Statement

Income Statement is composed of the following two elements:
Income: What

the business has earned over a period (e.g. sales revenue, dividend income, etc.)
Expense: The cost incurred by the business over a period (e.g. salaries and wages, depreciation, rental charges, etc.)
Net profit or loss is arrived by deducting expenses from income.

Cost Accounting Costs incurred to produce and sell an item or

Cost Accounting

Costs incurred to produce and sell an item or product

are classified as:
Direct labor
Direct material
Manufacturing cost
Administrative cost
Selling cost
Слайд 10

Direct Costs Direct material: Material whose cost is directly charged to

Direct Costs
Direct material:
Material whose cost is directly charged to a product
Measured

as the sum of charges for materials necessary to produce the product
Direct labor:
Labor cost directly attributable to a product
Measured by multiplying direct labor hours by the hourly wage rate
Слайд 11

Manufacturing Costs Factory Overhead: Indirect labor costs (sick leaves, vacations, bonuses

Manufacturing Costs

Factory Overhead:
Indirect labor costs (sick leaves, vacations, bonuses as well

as labor connected to inspection, cleaning…)
Indirect material costs (costs of materials that cannot be attributed to a particular product)
Fixed costs (taxes, insurance, depreciation, maintenance)
Factory Costs are the sum of:
Direct labor costs
Direct material costs
Factory overhead
Слайд 12

Administrative and Selling Costs Administrative costs: Salaries of executive and clerical

Administrative and Selling Costs

Administrative costs:
Salaries of executive and clerical personnel, office

space, traveling, auditing, necessary to direct the whole enterprise (not just its production or selling activities)
Selling costs
Any expense involved in selling the products or services that tie in directly with sales (selling commissions, market surveys, selling bags, advertising)

DEPRECIATION Decrease in value of physical properties with passage of time

DEPRECIATION
Decrease in value of physical properties with passage of time and

use
Accounting concept establishing annual deduction against before-tax income
- to reflect effect of time and use on asset’s value in firm’s financial statement
Слайд 15

PROPERTY IS DEPRECIABLE IF IT MUST : be used in business

PROPERTY IS DEPRECIABLE IF IT MUST :

be used in business or

held to produce income
have a determinable useful life which is longer than one year
wear out, decay, get used up, become obsolete, or lose value from natural causes
not be inventory, stock in trade, or investment property
Слайд 16

DEPRECIABLE PROPERTY TANGIBLE - can be seen or touched personal property

DEPRECIABLE PROPERTY

TANGIBLE - can be seen or touched
personal property -

includes assets such as machinery, vehicles, equipment, furniture, etc...
real property - anything erected on, growing on, or attached to land
(Since land does not have a determinable life itself, it is not depreciable)
INTANGIBLE - personal property, such as copyright, patent or franchise (out of scope of the lecture)
Слайд 17

WHEN DEPRECIATION STARTS AND STOPS Depreciation starts when property is placed

WHEN DEPRECIATION STARTS AND STOPS

Depreciation starts when property is placed in

service for use in business or for production of income
Property is considered in service when ready and available for specific use, even if not actually used yet
Depreciation stops when cost of placing it in service has been recovered or it is retired from service
Слайд 18

DEPRECIATION CONCEPTS The following terms are used in the classical (historical)

DEPRECIATION CONCEPTS

The following terms are used in the classical (historical) depreciation

method equations:
N = depreciable life of the asset in years
P = adjusted or cost basis, including allowable adjustments (cost of improvement or theft)
D t = annual depreciation deduction in year t (1< t TD t = cummulative depreciation through year t
BV t = book value at the end of year k
BV N = book value at the end of the depreciable (useful) life
SV N = salvage value at the end of year N
d = the ratio of depreciation in any one year to the BV at the beginning of the year
Слайд 19

Value of an asset Market value The actual value an asset

Value of an asset

Market value
The actual value an asset can be

sold for
Book value
The depreciated value of an asset as shown on the accounting records of company. Not a useful measure of its market value
Salvage value
Actual value of an asset at the end of its useful life. It is the expected selling price of a property when the asset can no longer be used productively by its owner
Слайд 20

Book Value Let: P = adjusted cost basis BVt = book

Book Value

Let:
P = adjusted cost basis
BVt = book value at the

end of period t
Dt = depreciation during period t
Then:
BVt = BVt-1 – Dt
BVt = P - ∑jt=1 Dt

Capital versus expense

Consider a copy shop, which buys:
Ink and paper
Copying (Xerox)

machines
Ink and paper are used up when they are bought (for all practical purposes):
Treated as an expense
When company buys/uses $1000 of paper,
It is $1000 poorer (not counting any revenue)!
Слайд 22

Capital versus expense Copying (Xerox) machines are used up only slowly

Capital versus expense

Copying (Xerox) machines are used up only slowly over

time:
Treated as “capital goods”
When company buys a $1000 machine
It trades $1000 cash for $1000 in equipment
Not poorer at all! (assets just changed form)
That is why expenses can be deducted from the income fully and instantly, assets or capital need to be depreciated
Слайд 23

Definitions Capital gains: Item selling price greater than purchase price Depreciation

Definitions

Capital gains:
Item selling price greater than purchase price
Depreciation recapture:
Item selling price

greater than book value
(Up to purchase price)
Taxed as ordinary income
Capital loss:
Item sold for less than book value
Слайд 24

Example If at the end of 1 year I go out

Example

If at the end of 1 year
I go out of business

and sell my tools for $40K.
I bought them for $35K and Book Value=$25
How much capital gain (or loss) do I have?
If at the end of 5 years
I go out of business and sell my tools for $5K
I bought them for $35K and Book Value=$10
How much capital gain (or loss) do I have?
Note that book value may be 0 even when market value is positive!
Слайд 25

Salvage value If a salvage value is expected, Depreciation applies to

Salvage value

If a salvage value is expected,
Depreciation applies to P -

SV
Example:
If P = $35K and I expected $5K salvage value in year 5,
I would depreciate $30K over 5 years
(only $6K per year)
That is, ($35K-$5K)/5 instead of $35K/5
Ending book value would be $5K
No capital gain/loss unless real salvage value differs

Depreciation and taxes

Depreciation is treated as an expense
(i.e., a tax deduction)

in computation of income taxes
It is a fictitious expense!
No cash changes hands
Would you rather have that “expense” occur sooner or later?

Declining Balance Depreciation

Sometimes called constant percentage method or Matheson formula: assumes

that the annual cost of depreciation is a fixed percentage of the BV at the beginning of the year
Constant proportion loss in value of an asset
Depreciation rate: a constant percentage
Ddb (t) = BVdb(t - 1) × d
Ddb (t): depreciation amount in period t

P: purchase price
d: depreciation rate
Слайд 38

DB Depreciation D(1) = P × d D(2) = d ×

DB Depreciation

D(1) = P × d
D(2) = d × (P- D(1))

= P(1-d) × d
D(3) = d × (P- D(1)-D(2)) = P(1-d)2 × d


Ddb (t) = P(1-d)t-1 × d
Слайд 39

DB Depreciation D1 = P × d Ddb (t) = P(1-d)t-1

DB Depreciation

D1 = P × d
Ddb (t) = P(1-d)t-1 × d
Ddb

Example 3: Example 1 revisited

Use a depreciation rate of 40% for

declining-balance method. Consider the previous example 1
Ddb(1) = BV(0) * (0.4) = 7000 (0.4) = $2800
Ddb(2) = BV(1) * (0.4) = (7000–2800) (0.4)
Ddb(2) = $1680
BVdb(3) = 7000 (1-0.4)3 = $1512
Слайд 41

Double declining balance (DDB) Most common form of declining balance is

Double declining balance (DDB)

Most common form of declining balance is double

declining balance or 200% declining balance (it would have been the triple and more, if the law permitted it, but the double was the maximum rate allowed):
d = 2/n, where n = recovery period
Слайд 42

Example 4: example 2 revisited

Consider the same machine tool
d =

2/20 years
= 10% per year (or 0.1)
Depreciation in year 1 = 0.1($35,000)
We use $35,000 since that is the BV in year 0
= $3,500 (versus $1,575 for straight line)
Depreciation in year 2
= 0.1 (BV in t-1)
= 0.1 ($35,000 - $3,500) = $3,150, etc.

DDB With Conversion to SL at the Most Desirable Time Since

DDB With Conversion to SL at the Most Desirable Time

Since DDB

does not use a value for Salvage, we have three possible scenarios at time of disposal:
Over depreciation: Book Value < Salvage Value. Tax savings realized early. Small gain upon sale of the asset and taxes on the gain.
Exact depreciation: Book value = Salvage value. There are no tax consequences upon sale of the asset.
Under depreciation: Book Value > Salvage Value. Did not deduct as much as you could have and lost tax savings.
To allow companies take advantage of all the depreciation charges they are entitled to, they can switch from DDB to straight line at the most favorable time.

See Example 7-4

A piece of equipment used in a business

has a basis of $50.000 and is expected to have a $10.000 SV when replaced after 30.000 hours of use. Find its depreciation rate per hour of use, and find its BV after 10.000 hours of operation.
Solution
Depreciation per unit of production = ($50.000-$10000)/30.000 hours = $1.33 per hour
After 10.000 hours BV = $50.000 - $1.33*(10.000 hours) = 36.700

Assume in the previous (oil) example that the

price for oil is $23 per barrel and the expenses to produce oil (apart from the initial cost) are $380,000
Gross Depletion Income = 50,000*23 = $1,150,000
Depletion Rate = 22%
Percentage Depletion Charge = $253,000
Now check if that amount exceeds the maximum depletion charge allowed by law

Why do we calculate depreciation?

Since depreciation is an “expense” we can

use that expense to reduce our taxable income, and therefore reduce the amount of taxes we pay.
We have to know how much our equipment has depreciated to determine the deductions to be made.

Observations

Land is capital
Land purchase is not an expense!
Land sale proceeds are

not revenue!
Just convert cash assets into land, vice versa
Capital gains are revenue.
Income taxes are an additional expense
But the timing of this expense is critical!
Results can vary a great deal depending on the timing of depreciation

Net Income vs. Cash Flow Net income is an accounting means

Net Income vs. Cash Flow

Net income is an accounting means of

measuring a firm’s profitability based on the matching concept. Costs become expenses as they are matched against revenue. The actual timing of cash inflows and outflows are ignored.
Cash flow: Given the time value of money, it is better to receive cash now than later, because cash can be invested to earn more money. That is why cash flows are relevant data to use in project evaluation.
Слайд 75

Why Do We Use Cash Flow in Project Evaluation? Example: Both

Why Do We Use Cash Flow in Project Evaluation?

Example: Both companies

Sell for $130K:
Capital gain

= $20K
Sell for $100K:
Capital loss = $10K (offset against gains)
Note: with land there can’t be Depreciation Recapture. Why?
Слайд 86

Capital gain/loss Taxable income = Gross income (i.e., revenues or receipts)

Capital gain/loss

Taxable income =
Gross income (i.e., revenues or receipts)
Minus operating

expenses
Minus depreciation
Plus depreciation recapture
Plus capital gains
Minus capital losses
(up to size of capital gains, but no greater)

Tax-exempt example Phone company bond at 11%: $550/year, paid as $275

Tax-exempt example

Phone company bond at 11%:
$550/year, paid as $275 every 6

months
Tax = ($550) x (33.8%) = $185.9
After-tax income
$550 - $185.9 = $364.10
Municipal bond at 7.5% (tax exempt):
$375/year (after-tax income greater!)
Слайд 90

Observation A government bond (tax-exempt) at 7.5% may give higher income

Observation

A government bond (tax-exempt) at 7.5% may give higher income than

a private 11% bond!
Desirability will vary with income:
Higher income gives higher tax rate
Tax exemption becomes more desirable

Charitable deduction example

Assume the following tax rate:
tax rate = 38.4%
Charitable gift

of $1000:
Tax deduction = ($1000) x (38.4%) = $384
True cost of gift = $1000 - $384 = $616
Government is encouraging charity!
