Tutorial: Examining Earnings Quality
The evaluation of earnings per share should be a relatively straightforward process, but thanks to the magic of accounting, it has become a game of smoke and mirrors, accompanied by constantly mutating versions that seem to have come out of "Alice in Wonderland". Instead of Tweedle-Dee and Tweedle-Dum we have pro forma EPS and EBITDA. And, despite rumors to the contrary, the whisper number - the Cheshire cat of Wall Street - continues to exist as guidance.
To be fair, this situation cannot be totally blamed on management. Wall Street deserves as much blame due to its myopic focus on the near-term and knee-jerk reactions to 1 cent misses. A forecast is always only a guess - nothing more, nothing less - but Wall Street often forgets this. This, however, does create opportunities for investors who can evaluate the quality of earnings over the long run and take advantage of market overreactions.

How to Evaluate the Quality of EPS
To determine earnings quality, investors can rely on operating cash flow. The company can show a positive earnings on the income statement while also bearing a negative cash flow. This is not a good situation to be in for a long time, because it means that the company has to borrow money to keep operating. And at some point, the bank will stop lending and want to be repaid. A negative cash flow also indicates that there is a fundamental operating problem: either inventory is not selling or receivables are not getting collected. "Cash is king" is one of the few real truisms on Wall Street, and companies that don't generate cash are not around for long. Want proof? Just look at how many of the dotcom wonders survived!

If operating cash flow per share (operating cash flow divided by the number of shares used to calculate EPS) is greater than reported EPS, earnings are of a high quality because the company is generating more cash than is reported on the income statement. Reported (GAAP) earnings, therefore, understate the profitability of the company.
If operating cash flow per share is less than reported EPS, it means that the company is generating less cash than is represented by reported EPS. In this case, EPS is of low quality because it does not reflect the negative operating results of the company and overstates what the true (cash) operating results.

Let's say that Behemoth Software (BS for short) reported that its GAAP EPS was $1. Assume that this number was derived by following GAAP and that management did not fudge its books. And assume further that this number indicates an impressive growth rate of 20%. In most markets, investors would buy this stock.
However, if BS's operating cash flow per share were a negative 50 cents, it would indicate that the company really lost 50 cents of cash per share versus the reported $1. This means that there was a gap of $1.50 between the GAAP EPS and actual cash per share generated by operations. A red flag should alert investors that they need to do more research to determine the cause and duration of the shortfall. The 50 cent negative cash flow per share would have to be financed in some way, such as borrowing from a bank, issuing stock, or selling assets. These activities would be reflected in another section of the cash flow statement.
If BS's operating cash flow per share were $1.50, this would indicate that reported EPS was of high quality because actual cash that BS generated was 50 cents more than was reported under GAAP. A company that can consistently generate growing operating cash flows that are greater than GAAP earnings may be a rarity, but it is generally a very good investment.

Trends Are Also Important
Evaluating trends will also help you spot the worst-case scenario, which occurs when a company reports increasingly negative operating cash flow and increasing GAAP EPS. As discussed above, there may be legitimate reasons for this discrepancy (economic cycles, the need to invest for future growth), but if the company is to survive, the discrepancy cannot last long. The appearance of growing GAAP EPS even though the company is actually losing money can mislead investors. This is why investors should evaluate the legitimacy of a growing GAAP by analyzing the trend in debt levels, times interest earned, days sales outstanding and inventory turnover.
