Lesson 5 of 8
Two ratios that do not exist
A filer with no current ratio and no interest coverage, both for reasons stated in its own filings, and what to read instead of reaching for a third ratio.

In one minute
- A filer may present an unclassified balance sheet, in which case there is no current and non-current split and no current ratio can be computed at all.
- A filer that capitalises interest may report no interest expense, in which case no coverage ratio can be computed either.
- n/a is a reading. It says the question has to be asked with a different instrument, and it says which.
Everything in this course so far has assumed the usual instruments exist. At some filers they do not, and the most credit-sensitive business a reader is likely to meet is one of them.
What the product computes for one filer, and what it refuses
Computed
- Fixed asset turnover, 40.11 times.
- Capital expenditure to revenue, 0.79 percent.
- Operating leverage, negative 14.16.
- Free cash flow conversion, 0.76.
Refused, and reads n/a
The credit ratios
- Current ratio.
- Quick ratio.
- Interest coverage.
- Debt to equity.
Both refusals follow from the filing itself rather than from missing data.
Why there is no current ratio
Because there is no current and non-current split. A classified balance sheet, which separates assets and liabilities due within a year from the rest, is the usual presentation but it is not required of every filer. An entity whose operating cycle is longer than a year, which is true of a homebuilder whose inventory is land and houses under construction, may present an unclassified balance sheet instead.
At the filer above, no total current assets and no total current liabilities figure appears anywhere in its tagged filing history. The current ratio and the quick ratio therefore have no numerator and no denominator. They are not missing data. They do not exist.
Why there is no interest coverage
Because the income statement reports no interest expense, for the reason the previous course established: interest is capitalised into inventory under ASC 835-20 and released through cost of sales as homes close.
The product's rule here is specific. Where a filer reports zero interest expense against a positive operating income, interest coverage is refused rather than computed, because dividing by zero has no answer and printing a very large number would describe a company with no borrowings. The refusal is the accurate reading.
The habit this should produce
When a figure reads n/a, the useful question is not which other ratio to substitute. It is what the absence tells you about the filer.
An absent current ratio says the business has an operating cycle longer than a year, which is itself the most important thing about its working capital. An absent coverage ratio says the cost of credit is somewhere other than the interest line, which tells you to go and find it.
Both absences narrowed the search. A substituted ratio would have widened it.
Check yourself
Why does a filer sometimes present an unclassified balance sheet?
- To avoid disclosing working capital
- Because its operating cycle is longer than a year, which makes a current and non-current split unhelpful
- Because it reports under a different standard
Show the answer
Answer: B.
A homebuilder whose inventory is land and houses under construction is the standard case. No total current assets or liabilities appear anywhere in that filer's tagged history.What should a reader do when interest coverage reads n/a at a company with real borrowings?
- Substitute a leverage ratio and move on
- Go and find where the cost of credit is, which the absence has just told them is not the interest line
- Treat coverage as very high
Show the answer
Answer: B.
Treating it as very high would describe a debt-free company. The absence narrows the search; a substitution widens it.At the filer above, cash of 1,259.0 million sits against the first three years of the schedule totalling 1,177.0 million. What does that establish?
- That the company is safe
- That the cash on the balance sheet at that date exceeded the principal due in the first three years of the schedule as filed
- That the fifth year will be refinanced
Show the answer
Answer: B.
It is arithmetic on two figures from one filing. What happens to the fifth year is not established by anything in it.Sources

What this leaves out
- This is a heterodox tradition. The mainstream account of the same phenomenon differs, and nothing here is a forecast or a view on any security.
- The four refused figures are refused for this filer in this product. Another data source may print a number for some of them by making an assumption, and the assumption is what the refusal avoids.
- Cash at a year end covering the first three rungs of a schedule is a fact about one date. The cash will be spent and generated in the intervening years, and nothing about the fifth year follows from it.
- Nothing here is a view on Toll Brothers or on any security.
