divisions.
Average performance is not necessarily
good.
Seasonal factors can distort ratios.

Problems and Limitations(Continued)
Sometimes it is difficult to tell if a ratiovalue is good or bad.
Often, different ratios give differentsignals, so it is difficult to tell, on balance,whether a company is in a strong or weakfinancial condition.

Ratio Analysis Limitations
Ratios are presented on a percentagebasis
Relative size is ignored (e.g., both large &
small firms can be compared) It is assumed that all numbers used are
correct (consider both possible errors and
earnings management) If the numbers are not reliable, ratios are
not particularly useful

Limitations of Ratio Analysis
A firms industry category is often difficult to
identify
Published industry averages are only guidelines.
Rarely are two companies exactly the same. Accounting practices differ across firms
Sometimes difficult to interpret deviations in
ratios Industry ratios may not be desirable targets
Seasonality affects ratios

Analysts should understand the followingaspects when dealing with ratios
A ratio is not "the answer". A ratio is an indicator ofsome aspect of a company's performance in thepast. It does not reveal why things are as they are.Also a single ratio by itself is not likely to be veryuseful.
Differences in accounting policies can distortratios (e.g. inventory valuation, depreciationmethods).
Not all ratios are necessarily relevant to a particular
analysis. Analysts should know the questions forwhich they want to find answers, and know thequestions that particular ratios can help answer.
Ratio analysis does not stop with computation;
Interpretation of the result is vital

How homogeneous is the company?
Are the ratios comparable between divisionswithin a company? It is critical to derive
comparable industry ratios. However, manycompanies have multiple lines of business,making it difficult to identify the appropriateindustry to use in comparing companies.
Companies are required to provide segmentedinformation that allows the user to see theimpact of various segments on the overallcompany.

Are the results of the ratio analysis consistent?
An analyst needs to look at several ratios inconjunction in order to form a sensible
conclusion. Total portfolio of the companyshould be used instead of only one set of ratios.
A company must be viewed along all these linessince the company may have strengths and/or
weaknesses in different areas. For example, ahighly profitable company may have very poorshort-term liquidity.

Concerns
Is the ratio within a reasonable range forthe industry?
Analysts must look at a range of values fora particular ratio because a ratio can betoo high or too low.

Accounting Issues Are alternative companies' accounting treatments
comparable? In comparing companies, even within the same
industry, the companies may be using differentaccounting treatments and/or different estimates to
capture the same event. Companies could use different estimates tocalculate depreciation or bad debts expense.Companies could use different inventory methodsand may have operating versus capital leases in
the financial statements. All of these accountingchoices and estimates affect financial statements.
However with IFRS replacing every countriesGAAP, the issue of distortion by accounting
treatment should be minimised.

Looking Beyond The Numbers:
Good financial analysis involves more than just
calculating numbers.
There are Qualitative factors to be considered
when evaluating a companys future financialperformance.
These important and basic skills are necessary
when making business decisions, when
evaluating performance, and when forecasting
likely future developments.

Ratio Analysis Limitations of Ratio Analysis:
Usefulness dependent on the
accuracy of the figures Enron,WorldCom or Parmalat? Only a part of the jig-saw needs
other information to make fulljudgement
What has happened in the past is
not necessarily a pointer to whatwill happen in the future! Statistics always have
a limitation in that it dependswhen they are used and how theyare used.
No two businesses are fullycomparable as the differencesbetween them will alwaysinfluence the performance of thebusiness
Ratios do not always reflect thedegree of intuition/genius that
may influence the performance ofa business
