ACCA FR Syllabus C. Analysing And Interpreting The Financial Statements - Ratio limitations - Notes 1 / 1
Ratios aren't always comparable
Factors affecting comaparability
Different accounting policies
Eg One company may revalue its property; this will increase its capital employed and (probably) lower its ROCE
Others may carry their property at historical cost
Different accounting dates
Eg One company has a year ended 30 June, whereas another has 30 September
If the sector is exposed to seasonal trading, this could have a significant impact on many ratios.
Different ratio definitions
Eg This may be a particular problem with ratios like ROCE as there is no universally accepted definition
Comparing to averages
Sector averages are just that: averages
Many of the companies included in the sector may not be a good match to the type of business being compared
Some companies go for high mark-ups, but usually lower inventory turnover, whereas others go for selling more with lower margins
Possible deliberate manipulation (creative accounting)
Different managerial policies
e.g. different companies offer customers different payment terms
Compare ratios with
Industry averages
Other businesses in the same business
With prior year information
Future raising of capital cannot be ascertained through ratio analysis.
