Although headlines still spray earnings figures all over the media every day, many investors have moved past net earnings as a measure of a company's economic output. That's because an earnings statement is very often less trustworthy than a cash flow statement because it's more open to manipulation based on dubious judgment calls.

The unreliability of the income statement is one of the reasons Foolish investors often flip straight past the income statement and balance sheet to eyeball the cash flow statement. In general, by taking a close look at the cash moving in and out of the business, you can get a better look at whether the last batch of earnings brought money into the company or merely disguised a cash gusher with a pretty headline.

Calling all cash flows
It's worth checking up on your companies' free cash flow (FCF) once a quarter or so to see if it bears any relationship to the net income in the headlines. That's what brings us to Adobe Systems (Nasdaq: ADBE), which has produced $833 million in FCF over the trailing 12 months, compared to $380 million in net income.


That means that Adobe turned 26% of its revenues into FCF. That looks amazing, but it always pays to compare that figure to sector and industry peers and competitors to see how your company stacks up.

Among its competitors and peers, Ansys comes in with the highest FCF margin (defined as FCF / trailing 12 months' revenue), with 33% of its revenues turning into FCF. But Adobe's performance looks pretty good.

All cash is not equal
Unfortunately, the cash flow statement isn't immune from nonsense, either. That's why it pays to take a close look at the components of free cash flow from operations, to make sure that these sources of cash are of good quality: in other words, that they're real, and replicable, in the upcoming quarters and not offset by continual cash outflows that don't appear on the income statement (such as major capital expenditures). For instance, cash flow based on cash net income and predictable depreciation are generally good stuff. An increase in cash flow based on stiffing your suppliers (by increasing accounts payable) or stiffing Uncle Sam on taxes, those will come back to bite investors later. The same goes for decreasing accounts receivable. This is good to see, but it's ordinary in recessionary times, and you can only increase collections so much.

So, how does the cash flow at Adobe look? Take a peek at the chart below, which flags questionable cash flow sources with a red bar.


I characterize as questionable cash flow statement line items such as changes in taxes payable, tax benefits from stock options, asset sales, and other items. That's not to say that companies booking these as sources of cash flow are weak or are engaging in any sort of wrongdoing. But whenever a company is getting more than, say, 10% of its cash from operations from these questionable sources, I feel obliged to crack open the filings and dig even deeper to make sure I am in touch with the true cash profitability.

With questionable cash sources comprising 27% of the cash flow from operations for Adobe Systems , I think it's time to do a little more digging. A quick check on the numbers shows that of the funky-looking $265 million, nearly $200 million is cash flow related to stock-based compensation and tax benefits of same. Most of the rest is deferred income taxes. Since stock-based compensation usually has to be soaked up later through share buybacks, and taxes eventually get paid, a conservative investor would probably lop a lot of that off Adobe's FCF and assume that equity investors get less than the $833 million of simple FCF.

Foolish final thought
If you are the kind of investor who takes the time to read past the headlines and crack a filing now and then, you're probably ahead of 95% of the rest of the individual investors out there. By keeping an eye on the health of your companies' cash flow, you can spot potential trouble early, or figure out if Mr. Market's pessimism is warranted by the numbers.
