In the quest to find great investments, most investors focus on earnings to gauge a company's financial strength. This is a good start, but earnings can be misleading and incomplete. To get a clearer understanding of a company's ability to earn money and reward you, the shareholder, it's often better to focus on cash flow. In this series, we tear apart a company's cash flow statement to see how much money is truly being earned and, more importantly, what management is doing with that cash.

Step on up, Flowserve (NYSE: FLS).

The first step in analyzing cash flow is to look at net income. Flowserve's net income over the last five years has been impressive:

Normalized Net Income $367 million $331 million $365 million $369 million $226 million

Next we add back in a few non-cash expenses, like the depreciation of assets, and adjust net income for changes in inventory, accounts receivable, and accounts payable -- changes in cash levels that reflect a company either paying its bills, or being paid by customers. This yields a figure called "cash from operating activities" -- the amount of cash a company generates from doing everyday business.

From there we subtract capital expenditures, or the amount a company spends acquiring or fixing physical assets. This yields one version of a figure called "free cash flow," or the true amount of cash a company has left over for its investors after doing business:

Free Cash Flow $110 million $254 million $323 million $282 million $329 million

Now we know how much cash Flowserve is really pulling in each year. Next question: What is it doing with that cash?

There are two ways a company can use free cash flow to directly reward shareholders: dividends and share repurchases. Cash not returned to shareholders can be stashed in the bank, invested in other companies and assets, or used to pay off debt.

Here's how much Flowserve has returned to shareholders in recent years:

2007

Dividends $70 million $64 million $59 million $51 million $26 million
Share Repurchases $150 million $46 million $41 million $165 million $45 million
Total Returned to Shareholders $220 million $110 million $100 million $216 million $70 million

As you can see, the company has repurchased a decent amount of its own stock. That's caused shares outstanding to fall, if only slightly:

Shares Outstanding (millions) 56 56 56 57 57

Now, companies tend to be fairly poor at repurchasing their own shares, buying feverishly when shares are expensive and backing away when they're cheap. Does Flowserve fall into this trap? Let's take a look:

This doesn't tell us much. Flowserve's buybacks have been sporadic, but it doesn't look like market swings have dictated management's buyback behavior. Given reasonable valuations, these buybacks have likely been a decent deal for shareholders.

Finally, I like to look at how dividends have added to total shareholder returns:

Shares returned 87% over the last five years, which increases to 98% with dividends reinvested -- a nice boost to top off already high performance.

To gauge how well a company is doing, keep an eye on the cash. How much a company earns is not as important as how much cash is actually coming in the door, and how much cash is coming in the door isn't as important as what management actually does with that cash. Remember, you, the shareholder, own the company. Are you happy with the way management has used Flowserve's cash? Sound off in the comment section below.
