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, Baker Hughes (NYSE: BHI).

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

Normalized Net Income $1.7 billion $881 million $391 million $1.5 billion $1.4 billion

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:

Now we know how much cash Baker Hughes is really pulling in each year -- or in this case, sending out. Next question: What's it paying to shareholders?

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

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

2007

Dividends $261 million $241 million $185 million $173 million $167 million
Share Repurchases -- -- -- $627 million $521 million
Total Returned to Shareholders $261 million $241 million $185 million $800 million $688 million

As you can see, the company has repurchased a decent amount of its own stock. But combined with other rounds of share issuance, shares outstanding have actually increased:

Shares Outstanding (millions) 436 394 310 307 318

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 Baker Hughes fall into this trap? Let's take a look:

Not great. Baker Hughes' only significant buybacks over the last five years came when shares were at or near their peak. Whether the subsequent pullback was a prudent way to save cash as it looked like the economy was about to implode, or a classic example of buying high and panicking low, is up for debate. In general, it doesn't appear management has been the most astute buyer of its own stock.

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

Shares returned -37% without dividends over the last five years, which rises to -33% including dividends -- a small boost to top off otherwise poor 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 Baker Hughes's cash? Sound off in the comment section below.
