A number of readers wrote in asking for more information. Two major components of corporate reporting -- the balance sheet and the income statement -- are covered in TSC's The Basics of Fundamental Analysis series.

To complete the picture, let's review the statements of cash flow for three companies, Anheuser-Busch (BUD - commentary - Cramer's Take), Amazon.com (AMZN - commentary - Cramer's Take) and Revlon (REV - commentary - Cramer's Take).

But first some history.

Before the mid-1980s, most investors and stock analysts thought the balance sheet and income statement provided sufficient information for decision-making.

The balance sheet provided a snapshot of financial condition (i.e., cash on hand; short- and long-term assets like accounts receivable and plant, property and equipment, and short- and long-term liabilities like accounts payable and corporate debt). The income statement summarized revenues and costs of doing business in net income and earnings per share.

The problem with the income statement is that accounting assumptions about depreciation, writedowns of goodwill and revenue recognition allow corporate management considerable leeway in generating the net income figures.

For example, in the early 1980s, Oracle (ORCL - commentary - Cramer's Take) aggressively recognized revenue from the sale of products that wouldn't ship for months but allowed the company to declare higher earnings in the current quarter. When the products failed to ship, Oracle was forced -- in a costly blow to shareholders -- to restate earnings.

On the other hand, Microsoft (MSFT - commentary - Cramer's Take) has an accounting policy of deferring some current sales to future accounting periods. This policy allows Microsoft to better match the costs of supporting a product with the revenues it generates, but it also allows the company to "smooth" earnings by controlling the recognition of that revenue.

In 1987, the Financial Accounting Standards Board (FASB), the nongovernmental organization charged with improving financial reporting standards, required companies to break out actual cash movements related to operating, investing and financing activities.

This new standard imposed a critical reality check on the income statement. A company with rapid income growth should also have dramatic increases in cash. If cash is in fact declining, there may be a problem with an accounting policy (or occasionally outright fraud) or the company may be in a higher-risk "development stage" situation.

The important information for investors is summarized in sections of the cash flow statement labeled "cash from operations," "cash from investing" and "cash from financing."

Cash from operations includes cash collected regardless of when revenues were generated or recognized and costs associated with sales and with increasing or decreasing inventories.

Cash from investment focuses on capital expenditures, such as investment in new plant, property and equipment or purchasing or divesting a stake in another company.

Cash from financing includes increases due to share offerings and debt sales or decreases due to dividend declarations, share repurchases or the retirement of debt.

Doing that for brewing giant Anheuser-Busch returns the following:

The first thing you'll notice is that this company throws off a pretty healthy $1.4 billion to $2.2 billion a year. This money can be used for marketing and distribution, buying back shares, buying competitors or increasing advertising, among other things. Companies with positive cash flow from operations have many choices.

As you might expect, Anheuser-Busch is using some cash flow to upgrade and maintain its brewery operations and is also using some of its operating cash flow to acquire other business lines.

Anheuser-Busch appears to have a stock buyback program in place (hence the expenditure of cash on treasury stock) as well as a stock option program (thus the gain of cash from the Issued Stock Plan). If you wanted to know for sure, you would review the company's actual Securities and Exchange Commission filings. The company paid out more than $521 million in dividends and also increased long-term debt by just under $400 million dollars.

The overall trend is that Anheuser-Busch is changing its debt-to-equity ratio in favor of debt, which has the benefit of increasing earnings per share faster than overall revenue growth. But it also increases the riskiness of the company.

Overall, Anheuser-Busch is a classic "cash cow" company. Net income has increased only 19.5% over the past five years. Earnings per share have grown 111.4% over the past five years, however, as the company has reduced the number of shares outstanding. Overall, Anheuser-Busch is a fairly conservative addition to any portfolio.

What about Amazon.com?

Despite losing $125 million in net income, Amazon.com had positive cash flow in the most recent year. As a "virtual" corporation, Amazon has very little depreciation. You'd have to research how a merger generated $47 million and how noncash interest generated $24 million. Some money was spent on inventories, no doubt all the new product lines Amazon introduced last year. Most interestingly, Amazon generated nearly $100 million in cash by increasing accounts payables and other liabilities -- essentially "borrowing" from suppliers. That development has to be monitored going forward.

Again, as a "virtual" corporation, Amazon made only a tiny investment in plant, property and equipment last year. A net $214 million of cash was deposited in short-term investments (most likely money market securities), which is to say that Amazon is conserving a huge cash hoard for future opportunities.

Amazon took advantage of the positive investment outlook for the Internet sector over the past two years, raising a net $380 million in stock offerings and debt issuance. It may not be so easy to issue further securities this year, but with $214 million in the bank, the company can coast for a while.

Amazon is transitioning from "problem child" to "star" status. It's obviously a riskier investment than Anheuser-Busch, but justifiable given Amazon's triple-digit revenue growth.

Lastly, Revlon:

Hmm -- a lot to worry about since basic operations are cash flow negative. Without the $51.7 million extraordinary item and $64.2 million from discontinued operations, cash flow of operations would have generated minus $167.4 million. Included in net income (as we see by double-checking the income statement) is $137.9 million in interest expense -- this company is choking to death on too much debt.

We see a variety of maneuverings, which used a net $108 million.

We see a very complicated financial structure, which raised an aggregate $159 million. We saw above that debt service cost $137.9 million last year, so, effectively, Revlon had to borrow money just to keep current.

Overall, Revlon would fall in the "dog" category (slow growth, negative operating cash flow) and would be best avoided for now.

Conclusions:
