1. Introduction
As a manager, you may want to reward employees based on their performance. How do you know
how well they have done? How can you determine what departments or divisions have performed
well? As a lender, how do decide the borrower will be able to pay back as promised? As a manager of
a corporation how do you know when existing capacity will be exceeded and enlarged capacity will be
needed? As an investor, how do you predict how well the securities of one company will perform
relative to that of another? How can you tell whether one security is riskier than another? We can
address all of these questions through financial analysis.
Financial analysis is the selection, evaluation, and interpretation of financial data, along with other
pertinent information, to assist in investment and financial decision-making. Financial analysis may be
used internally to evaluate issues such as employee performance, the efficiency of operations, and
credit policies, and externally to evaluate potential investments and the credit-worthiness of
borrowers, among other things.
The analyst draws the financial data needed in financial analysis from many sources. The primary
source is the data provided by the company itself in its annual report and required disclosures. The
annual report comprises the income statement, the balance sheet, and the statement of cash flows,
as well as footnotes to these statements. Certain businesses are required by securities laws to
disclose additional information.
Besides information that companies are required to disclose through financial statements, other
information is readily available for financial analysis. For example, information such as the market
prices of securities of publicly-traded corporations can be found in the financial press and the
electronic media daily. Similarly, information on stock price indices for industries and for the market
as a whole is available in the financial press.
Another source of information is economic data, such as the Gross Domestic Product and Consumer
Price Index, which may be useful in assessing the recent performance or future prospects of a
company or industry. Suppose you are evaluating a company that owns a chain of retail outlets.
What information do you need to judge the company's performance and financial condition? You
need financial data, but it doesn't tell the whole story. You also need information on consumer

spending, producer prices, consumer prices, and the competition. This is economic data that is
readily available from government and private sources.
Besides financial statement data, market data, and economic data, in financial analysis you also need
to examine events that may help explain the company's present condition and may have a bearing on
its future prospects. For example, did the company recently incur some extraordinary losses? Is the
company developing a new product? Or acquiring another company? Is the company regulated?
Current events can provide information that may be incorporated in financial analysis.
The financial analyst must select the pertinent information, analyze it, and interpret the analysis,
enabling judgments on the current and future financial condition and operating performance of the
company. In this reading, we introduce you to financial ratios -- the tool of financial analysis. In
financial ratio analysis we select the relevant information -- primarily the financial statement data --
and evaluate it. We show how to incorporate market data and economic data in the analysis and
interpretation of financial ratios. And we show how to interpret financial ratio analysis, warning you
of the pitfalls that occur when it's not used properly.
We use Microsoft Corporation's 2004 financial statements for illustration purposes throughout this
reading. You can obtain the 2004 and any other year's statements directly from Microsoft. Be sure to
save these statements for future reference.
Classification of ratios
A ratio is a mathematical relation between one quantity and another. Suppose you have 200 apples
and 100 oranges. The ratio of apples to oranges is 200 / 100, which we can more conveniently
express as 2:1 or 2. A financial ratio is a comparison between one bit of financial information and
another. Consider the ratio of current assets to current liabilities, which we refer to as the current
ratio. This ratio is a comparison between assets that can be readily turned into cash -- current assets
-- and the obligations that are due in the near future -- current liabilities. A current ratio of 2:1 or 2
means that we have twice as much in current assets as we need to satisfy obligations due in the near
future.
Ratios can be classified according to the way they are constructed and their general characteristics.
By construction, ratios can be classified as a coverage ratio, a return ratio, a turnover ratio, or a
component percentage:
1. A coverage ratio is a measure of a company's ability to satisfy (meet) particular obligations.
2. A return ratio is a measure of the net benefit, relative to the resources expended.
3. A turnover ratio is a measure of the gross benefit, relative to the resources expended.
4. A component percentage is the ratio of a component of an item to the item.
When we assess a company's operating performance, we want to know if it is applying its assets in
an efficient and profitable manner. When we assess a company's financial condition, we want to
know if it is able to meet its financial obligations.
There are six aspects of operating performance and financial condition we can evaluate from financial
ratios:
1. A liquidity ratio provides information on a company's ability to meet its short−term,
immediate obligations.
2. A profitability ratio provides information on the amount of income from each dollar of
sales.

3. An activity ratio relates information on a company's ability to manage its resources (that is,
its assets) efficiently.
4. A financial leverage ratio provides information on the degree of a company's fixed
financing obligations and its ability to satisfy these financing obligations.
5. A shareholder ratio describes the company's financial condition in terms of amounts per
share of stock.
6. A return on investment ratio provides information on the amount of profit, relative to the
assets employed to produce that profit.
We cover each type of ratio, providing examples of ratios that fall into each of these classifications.
2. Liquidity Ratios
Liquidity reflects the ability of a company to meet its short-term obligations using assets that are
most readily converted into cash. Assets that may be converted into cash in a short period of time
are referred to as liquid assets; they are listed in financial statements as current assets. Current
assets are often referred to as working capital because these assets represent the resources needed
for the day-to-day operations of the company's long-term, capital investments. Current assets are
used to satisfy short-term obligations, or current liabilities. The amount by which current assets
exceed current liabilities is referred to as the net working capital.1
The role of the operating cycle
How much liquidity a company needs depends on its operating cycle. The operating cycle is the
duration between the time cash is invested in goods and services to the time that investment
produces cash. For example, a company that produces and sells goods has an operating cycle
comprising four phases:
(1) purchase raw material and produce goods, investing in inventory;
(2) sell goods, generating sales, which may or may not be for cash;
(3) extend credit, creating accounts receivables, and
(4) collect accounts receivables, generating cash.
The operating cycle is the length of time it takes to convert an investment of cash in inventory
back into cash (through collections of sales). The net operating cycle is the length of time it takes to
convert an investment of cash in inventory and back into cash considering that some purchases are
made on credit.
The number of days a company ties up funds in inventory is determine by:
(1) the total amount of money represented in inventory, and
(2) the average day's cost of goods sold.
The current investment in inventory -- that is, the money "tied up" in inventory -- is the ending
balance of inventory on the balance sheet. The average day's cost of goods sold is the cost of goods
1
You will see reference to the net working capital (i.e., current assets – current liabilities) as simply working
capital, which may be confusing. Always check the definition for the particular usage because both are common
uses of the term working capital.

sold on an average day in the year, which can be estimated by dividing the cost of goods sold found
on the income statement by the number of days in the year.
We compute the number of days of inventory by calculating the ratio of the amount of inventory on
hand (in dollars) to the average day's Cost of Goods Sold (in dollars per day):
365/soldgoodsofCost
Inventory
soldgoodsofcostsday'Average
Inventory
inventorydaysofNumber ==
If the ending inventory is representative of the inventory throughout the year, the number of days
inventory tells us the time it takes to convert the investment in inventory into sold goods. Why worry
about whether the year-end inventory is representative of inventory at any day throughout the year?
Well, if inventory at the end of the fiscal year-end is lower than on any other day of the year, we
have understated the
number of days of
inventory.
Indeed, in practice most
companies try to choose
fiscal year-ends that
coincide with the slow
period of their business.
That means the ending
balance of inventory would
be lower than the typical
daily inventory of the year.
We could, for example,
look at quarterly financial
statements and take
averages of quarterly
inventory balances to get
a better idea of the typical
inventory. However, here
for simplicity in this and
other ratios, we will make
a note of this problem and
deal with it later in the
discussion of financial
ratios.
We can extend the same
logic for calculating the
number of days between a
sale -- when an account
receivable is created -- to
the time it is collected in
cash. If the ending
balance of receivables at
the end of the year is
representative of the
receivables on any day throughout the year, then it takes, on average, approximately the "number of
days credit" to collect the accounts receivable, or the number of days receivables:

Wal-Mart Stores, Inc., had cost of revenue of $219,793 million for the fiscal
year ended January 31, 2005. It had an inventory balance of $29,447 million
at the end of this fiscal year. Using the quarterly information, Wal-Mart’s
average inventory balance during the fiscal year is $29,769.25:

Based on this information, what is Wal-Mart’s inventory turnover for fiscal year
2004 (ending January 31, 2005)?
Solution:
Using the fiscal year end balance of inventory:
= =
$29,447 $29, 447
Number of days inventory = 48.9 days
$219,793/365 $602.173
Using the average of the quarterly balances:
= =
$29,769.25 $29,769.25
$219,793/365 $602.173
In other words, it takes Wal-Mart approximately 50 days to sell its
merchandise from the time it acquires it.

What does the operating cycle have to do with liquidity? The longer the operating cycle, the more
current assets needed (relative to current liabilities) because it takes longer to convert inventories
and receivables into cash. In other words, the longer the operating cycle, the more net working
capital required.
We also need to look at the liabilities on the balance sheet to see how long it takes a company to pay
its short-term obligations. We can apply the same logic to accounts payable as we did to accounts
receivable and inventories. How long does it take a company, on average, to go from creating a
payable (buying on credit) to paying for it in cash?
= =
Accounts payable Accounts payable
Number of days payables
Average day's purchases Purchases / 365
First, we need to determine the amount of an average day's purchases on credit. If we assume all
purchases are made on credit, then the total purchases for the year would be the Cost of Goods Sold,
less any amounts included in this Cost of Goods Sold that are not purchases.2
The operating cycle tells us how long it takes to convert an investment in cash back into cash (by
way of inventory and accounts receivable):
Number of days Number of days
Operating cycle
of inventory of receivables
= +
The number of days of purchases tells us how long it takes use to pay on purchases made to create
the inventory. If we put these two pieces of information together, we can see how long, on net, we
tie up cash. The difference between the operating cycle and the number of days of payables is the
net operating cycle:
Net operating cycle = Operating Cycle - Number of days of purchases
or, substituting for the operating cycle,
purchasesof

The net
operating cycle
therefore tells
us how long it
takes for the
company to get
cash back from
its investment
in inventory
and accounts
receivable,
considering that
purchases may be made on credit. By not paying for purchases immediately (that is, using trade
credit), the company reduces its liquidity needs. Therefore, the longer the net operating cycle, the
greater the company’s need for liquidity.
Microsoft's Number of Days Receivables
2004:
Average day's receivables = $36,835 million / 365 = $100.9178 million
Number of days receivables = $5,890 million / $100.9178 million = 58.3643 days
Now try it for 2005 using the 2005 data from Microsoft’s financial statements.

For example, depreciation is included in the Cost of Goods Sold, yet it not a purchase. However, as a quite
proxy for purchases, we can use the accounting relationship: beginning inventory + purchases = COGS + ending
inventory.

Measures of liquidity
Liquidity ratios provide a measure of a company’s ability to generate cash to meet its immediate
needs. There are three commonly used liquidity ratios:
1. The current ratio is the ratio of current assets to current liabilities; Indicates a company's
ability to satisfy its current liabilities with its current assets:
sliabilitieCurrent
assetsCurrent
ratioCurrent =
2. The quick ratio is the ratio of quick assets (generally current assets less inventory) to
current liabilities; Indicates a company's ability to satisfy current liabilities with its most
liquid assets
sliabilitieCurrent
Inventory-assetsCurrent
ratioQuick =
3. The net working capital to sales ratio is the ratio of net working capital (current assets
minus current liabilities) to sales; Indicates a company's liquid assets (after meeting
short−term obligations) relative to its need for liquidity (represented by sales)
Sales
sliabilitieCurrent-assetsCurrent
ratiosalestocapitalworkingNet =
Generally, the larger these liquidity ratios, the better the ability of the company to satisfy its
immediate obligations. Is there a magic number that defines good or bad? Not really.
Consider the current ratio. A large amount of current assets relative to current liabilities provides
assurance that the company will be able to satisfy its immediate obligations. However, if there are
more current assets than the company needs to provide this assurance, the company may be
investing too heavily in these non- or low-earning assets and therefore not putting the assets to the
most productive use.
Another consideration is the
operating cycle. A company
with a long operating cycle
may have more need to
liquid assets than a
company with a short
operating cycle. That’s
because a long operating
cycle indicate that money is
tied up in inventory (and then receivables) for a longer length of time.

3. Profitability ratios
Profitability ratios (also referred to as profit margin ratios) compare components of income with sales.
They give us an idea of what makes up a company's income and are usually expressed as a portion
of each dollar of sales. The profit margin ratios we discuss here differ only by the numerator. It's in
the numerator that we reflect and thus evaluate performance for different aspects of the business:
The gross profit margin is the ratio of gross income or profit to sales. This ratio indicates how
much of every dollar of sales is left after costs of goods sold:
Gross income
Gross profit margin
Sales
=
The operating profit margin is the
ratio of operating profit (a.k.a. EBIT,
operating income, income before
interest and taxes) to sales. This is a
ratio that indicates how much of each
dollar of sales is left over after operating
expenses:
Microsoft's 1998 Profit Margins
Gross profit margin = ($14,484 - 1,197)/$14,484 = 91.736%
Operating profit margin = $6,414 / $14,484 = 44.283%
Net profit margin = $4,490 / $14,484 = 31%

4. Activity ratios
Activity ratios are measures of how well assets are used. Activity ratios -- which are, for the most
part, turnover ratios -- can be used to evaluate the benefits produced by specific assets, such as
inventory or accounts receivable. Or they can be use to evaluate the benefits produced by all a
company's assets collectively.
These measures help us gauge how effectively the company is at putting its investment to work. A
company will invest in assets – e.g., inventory or plant and equipment – and then use these assets to
generate revenues. The greater the turnover, the more effectively the company is at producing a
benefit from its investment in assets.
The most common turnover ratios are the following:
1. Inventory turnover is the ratio of cost of goods sold to inventory. This ratio indicates how
many times inventory is created and sold during the period:
Inventory
soldgoodsofCost
turnoverInventory =
2. Accounts receivable turnover is the ratio of net credit sales to accounts receivable. This
ratio indicates how many times in the period credit sales have been created and collected on:

receivableAccounts

turnoverreceivableAccounts =
3. Total asset turnover is the ratio of sales to total assets. This ratio indicates the extent that
the investment in total assets results in sales.
assetsTotal

4. Fixed asset turnover is the ratio of sales to fixed assets. This ratio indicates the ability of
the company’s management to put the fixed assets to work to generate sales:

Accounts receivable turnover = $36,835 / $5,890 = 6.2538 times

Report 2005
Turnovers and numbers of days
You may have noticed that there is a relation between the measures of the operating cycle and
activity ratios. This is because they use the same information and look at this information from
different angles. Consider the number of days inventory and the inventory turnover:
=
Inventory
Number of days inventory
Average day's cost of goods sold
Inventory
soldgoodsofCost
turnoverInventory =
The number of days inventory is how long the inventory stays with the company, whereas the
inventory turnover is the number of times that the inventory comes and leaves – the complete cycle
– within a period. So if the number of days inventory is 30 days, this means that the turnover within
the year is 365 / 30 = 12.167 times. In other words,
= =
365 365 Cost of goods sold
Inventory turnover =
InventoryNumber of days inventory Inventory
Cost of goods sold / 365

$219,793/365 $602.173
Wal-Mart’s inventory turnover is:

$219,793
Inventory turnover = 7.464 times
$29,447
And the number of days and turnover are related as follows:
Inventory turnover = 365 / 48.9 = 7.464 times
Number of days inventory = 365 / 7.464 = 48.9 days
5. Financial leverage ratios
A company can finance its assets either with equity or debt. Financing through debt involves risk
because debt legally obligates the company to pay interest and to repay the principal as promised.
Equity financing does not obligate the company to pay anything -- dividends are paid at the
discretion of the board of directors. There is always some risk, which we refer to as business risk,
inherent in any operating segment of a business. But how a company chooses to finance its
operations -- the particular mix of debt and equity -- may add financial risk on top of business risk
Financial risk is the extent that debt financing is used relative to equity.
Financial leverage ratios are used to assess how much financial risk the company has taken on. There
are two types of financial leverage ratios: component percentages and coverage ratios. Component
percentages compare a company's debt with either its total capital (debt plus equity) or its equity
capital. Coverage ratios reflect a company's ability to satisfy fixed obligations, such as interest,
principal repayment, or lease payments.
Component-percentage financial leverage ratios
The component-percentage financial leverage ratios convey how reliant a company is on debt
financing. These ratios compare the amount of debt to either the total capital of the company or to
the equity capital.
1. The total debt to assets ratio indicates the proportion of assets that are financed with
debt (both short−term and long−term debt):
assetsTotal
debtTotal
ratioassetstodebtTotal =
Remember from your study of accounting that total assets are equal to the sum of total debt
and equity. This is the familiar accounting identity: assets = liabilities + equity.
2. The long−term debt to assets ratio indicates the proportion of the company's assets that
are financed with long−term debt.
assetsTotal
debtterm-Long
ratioassetstodebtterm-Long =

3. The debt to equity ratio (a.k.a. debt-equity ratio) indicates the relative uses of debt and
equity as sources of capital to finance the company's assets, evaluated using book values of
the capital sources:
equityrs'shareholdeTotal
debtTotal
ratioequitytodebtTotal =
One problem (as we shall see)
with looking at risk through a
financial ratio that uses the book
value of equity (the stock) is that
most often there is little relation
between the book value and its
market value. The book value of
equity consists of:
• the proceeds to the
company of all the stock
issued since it was first
incorporated, less any
treasury stock (stock
repurchased by the
company); and
• the accumulation of all
the earnings of the
company, less any
dividends, since it was
first incorporated.
Let's look at an example of the
book value vs. market value of
equity. IBM was incorporated in
1911. So its book value of equity
represents the sum of all its stock
issued and all its earnings, less all dividends paid since 1911. As of the end of 2003, IBM's book value
of equity was approximately $28 billion and its market value of equity was approximately $162 billion.
The book value understates its market value by over $130 billion. The book value generally does not
give a true picture of the investment of shareholders in the company because:
Note that the debt-equity ratio is related to the debt-to-total assets
ratio because they are both measures of the company’s capital
structure. The capital structure is the mix of debt and equity that
the company uses to finance its assets.
Let’s use short-hand notation to demonstrate this relationship. Let D
represent total debt and E represent equity. Therefore, total assets
are equal to D+E.
If a company has a debt-equity ratio of 0.25, this means that is debt-
to-asset ratio is 0.2. We calculate it by using the ratio relationships
and Algebra:
D/E = 0.25
D = 0.25 E
Substituting 0.25 E for D in the debt-to-assets ratio D/(D+E):
D/(D+E) = 0.25 E / (0.25 E + E) = 0.25 E / 1.25 E = 0.2
In other words, a debt-equity ratio of 0.25 is equivalent to a debt-to-
assets ratio of 0.2
This is a handy device: if you are given a debt-equity ratio and need
the debt-assets ratio, simply:
D/(D+E) = (D/E) / (1 + D/E)
Why do we bother to show this? Because many financial analysts
discuss or report a company’s debt-equity ratio and you are left on
your own to determine what this means in terms of the proportion of
debt in the company’s capital structure.
• earnings are recorded according to accounting principles, which may not reflect the true
economics of transactions, and
• due to inflation, the dollars from earnings and proceeds from stock issued in the past do not
reflect today's values.
The market value, on the other hand, is the value of equity as perceived by investors. It is what
investors are willing to pay, its worth. So why bother with the book value of equity? For two reasons:
first, it is easier to obtain the book value than the market value of a company's securities, and
second, many financial services report ratios using the book value, rather than the market value.
We may use the market value of equity in the denominator, replacing the book value of equity. To do
this, we need to know the current number of shares outstanding and the current market price per
share of stock and multiply to get the market value of equity.

Coverage financial leverage ratios
In addition to the leverage ratios that use information about how debt is related to either assets or
equity, there are a number of financial leverage ratios that capture the ability of the company to
satisfy its debt obligations. There are many ratios that accomplish this, but the two most common
ratios are the times interest coverage ratio and the fixed charge coverage ratio.
The times-interest-coverage ratio, also referred to as the interest coverage ratio, compares the
earnings available to meet the interest obligation with the interest obligation:
Interest
taxesandinterestbeforeEarnings
ratiocoverage-interest-Times =
The fixed charge coverage ratio expands on the obligations covered and can be specified to include
any fixed charges, such as lease payments and preferred dividends. For example, to gauge a
company’s ability to cover its interest and lease payments, you could use the following ratio:
paymentLeaseInterest
paymentLeasetaxesandinterestbeforeEarnings
ratiocoveragecharge-Fixed

Coverage ratios are often used in debt covenants to help protect the creditors.

6. Shareholder ratios
The ratios we have explained to this point deal with the performance and financial condition of the
company. These ratios provide information for managers (who are interested in evaluating the
performance of the company) and for creditors (who are interested in the company's ability to pay its
obligations). We will now take a look at ratios that focus on the interests of the owners -- shareholder
ratios. These ratios translate the overall results of operations so that they can be compared in terms
of a share of stock:
Earnings per share (EPS) is the amount of income earned during a period per share of common
stock.
goutstandinsharesofNumber
rsshareholdetoavailableincomeNet
shareperEarnings =
As we learned earlier in the study of Financial Statement Information, two numbers of earnings per
share are currently disclosed in financial reports: basic and diluted. These numbers differ with respect
to the definition of available net income and the number of shares outstanding. Basic earnings per
share are computed using reported earnings and the average number of shares outstanding.
Diluted earnings per share are computed assuming that all potentially dilutive securities are
issued. That means we look at a “worst case” scenario in terms of the dilution of earnings from
factors such as executive stock options, convertible bonds, convertible preferred stock, and warrants.
Suppose a company has convertible securities outstanding, such as convertible bonds. In calculating
diluted earnings per share, we consider what would happen to both earnings and the number of

shares outstanding if these bonds were converted into common shares. This is a “What if?” scenario:
what if all the bonds are converted into stock this period. To carry out this “What if?” we calculate
earnings considering that the company does not have to pay the interest on the bonds that period
(which increases the numerator of earnings per share), but we also add to the denominator the
number of shares that would be issued if
these bonds were converted into shares.3
Another source of dilution is executive
stock options. Suppose a company has 1
million shares of stock outstanding, but
has also given its executives stock options
that would result in 0.5 million new shares
issued if they chose to exercise these
options. This would not affect the
numerator of the earnings per share, but
would change the denominator to 1.5
million shares. If the company had
earnings of $5 million, its basic earnings
per share would be $5 million / 1 million
shares = $5.00 per share and its diluted
earnings per share would be $5 million /
1.5 million shares = $3.33 per share.
What’s a convertible security?
A convertible security is a security – debt or equity – that
gives the investor the option to convert—that is, exchange –
the security into another security (typically, common stock).
Convertible bonds and convertible preferred stocks are
common.
Suppose you buy a convertible bond with a face value of
$1,000 that is convertible into 100 shares of stock. This
means that you own the bond and receive interest, but you
have the option to exchange it for 100 shares of stock. You
can hold the bond until it matures, collecting interest
meanwhile and then receiving the face value at maturity, or
you can exchange it for the 100 shares of stock at any time.
Your choice. Once you convert your bond into stock,
however, you no longer receive any interest on the bond.
Some issuers will limit conversion such that the bond cannot
be converted for a fixed number of years from issuance.
As an example, consider Yahoo!'s earnings per share reported in their 2004 annual report:
Item 2003 2004
Basic EPS $0.19 $0.62
Diluted EPS $0.18 $0.58
The difference between the basic and diluted earnings per share in Yahoo!'s case is attributable to its
extensive use of stock options in compensation programs.
Book value equity per share is the amount of the book value (a.k.a. carrying value) of common
equity per share of common stock, calculated by dividing the book value of shareholders’ equity by
the number of shares of stock outstanding. As we discussed earlier, the book value of equity may
differ from the market value of equity. The market value per share, if available, is a much better
indicator of the investment of shareholders in the company.
The price−earnings ratio (P/E or PE ratio) is the ratio of the price per share of common stock to
the earnings per share of common stock:
Market price per share
Price-earnings ratio =
Earnings per share
Though earnings per share are reported in the income statement, the market price per share of stock
is not reported in the financial statements and must be obtained from financial news sources. The

A “catch” is that diluted earnings per share can never be reported to be greater than basic earnings per share.
In some cases (when a company has many convertible securities outstanding), we may calculate a diluted
earnings per share greater than basic earnings per share, but in this case we cannot report diluted earnings per
share because it would be anti-dilutive.

P/E ratio is sometimes used as a proxy for investors' assessment of the company's ability to generate
cash flows in the future. Historically, P/E ratios for U.S. companies tend to fall in the 10-25 range, but
in recent periods (e.g., 2000-2001) P/E ratios have reached much higher. Examples of P/E ratios (P/E
ratios at the end of 2004): 4

We are often interested in the returns to shareholders in the form of cash dividends. Cash
dividends are payments made by the company directly to its owners. There is no requirement that
a company pay dividends to its shareholders, but many companies pay regular quarterly or annual
dividends to the owners. The decision to pay a dividend is made by the company’s board of
directors. Note that not all companies pay dividends.
Dividends per share (DPS) is the dollar amount of cash dividends paid during a period, per share
of common stock:
Dividends paid to shareholders
Dividends per share
Number of shares outstanding

The dividend payout ratio is the ratio of cash dividends paid to earnings for a period:
Dividends
Dividend payout ratio =
Earnings
The complement to the dividend payout ratio is the retention ratio or the plowback ratio:
Earnings - Dividends
Retention ratio =
Earnings
We can also convey information about dividends in the form of a yield, in which we compare the
dividends per share with the market price per share:
Dividends per share
Dividend yield =
Market price per share
The dividend yield is the return to shareholders measured in terms of the dividends paid during the
period.
We often describe a company's dividend policy in terms of its dividend per share, its dividend payout
ratio, or its dividend yield. Some companies' dividends appear to follow a pattern of constant or

constantly growing dividends per share. And some companies' dividends appear to be a constant
percentage of earnings.
Summary
You’ve been introduced to a few of the financial ratios that a financial analyst has in his or her toolkit.
There are hundreds of ratios that can be formed using available financial statement data. The ratios
selected for analysis depend on the type of analysis (e.g., credit worthiness) and the type of
company. You’ll see in the next reading how to use these ratios to get an understanding of a
company’s condition and performance.
