Today's Time Warner earnings announcement shows the disappointment that results when shareholders expect a corporate strategy and instead get a conglomerate. With TWX down 1.72% in the earnings announcement's wake, the Chinese water torture continues.  How so?

When a corporate strategy is well-conceived and well-executed, there is a strong economic reason for businesses to be under the same corporate umbrella. Simply put, corporate strategy is about creating value by sharing important capabilities across business units. For example, Wal-Mart gets big volume discounts by purchasing in big quantities from its suppliers. Wal-Mart is also good at measuring what items sell in its stores and which ones don't and stocking the shelves of each store accordingly. Wal-Mart's sustained financial excellence results from its ability to share these capabilities across its discount retailing, grocery, and pharmacy businesses. This sharing gives Wal-Mart a sustainable competitive advantage, keeping its costs below its competitors.

By contrast, a conglomerate holds a diverse collection of businesses among which there is very little sharing. The ostensible reason for the businesses being under the same corporate umbrella is that the different businesses can predictably offset each other's earnings cycles. When one business is down, another one is up and vice versa. The net effect is to smooth earnings.

0:00 I'm listening to the call just after the market open, so I'll report it to you in time elapsed on the call. Everyone's buzzing about Time Warner's much-higher-than-expected earnings, which have still disappointed investors (the stock was down 31 cents to $17.11 at last check). Revenues were just a touch up from the year-ago quarter, to $10.5 billion, and operating income was up 11% to $1.9 billion. The company is churning cash, too, with $1.6 billion in free cash flow.

The big story, of course, is that AOL revenue and income are both down from a year ago. Publishing is down in both areas, too, but no one seems to be mentioning that. If you're looking for good news, there's a lot of it: cable income is up significantly and both "Filmed Entertainment" and "Network" categories show some strong growth in income.

0:25 James Barge, SVP of Investor Relations, takes the mic. He explains the company's odd and non-GAAP measures, including (quite a mouthful) adjusted OIBDA (operating income before depreciation and amortization). It excludes some items, like "non-cash asset impairments" and amounts from sales of business lines. It seems like a sensible financial measure but it's hilarious to hear someone say it. [This from a girl whose friends, it must be admitted, tell accounting jokes to one another. Did you hear the one about EBCOSITDA? Oh, never mind.]
