Don't you just hate it when one of the companies in your portfolio finds itself the subject of litigation? Especially when it's a lawsuit not so much for money but to generate a little bad publicity? I know, lawsuits are part of the game of any business. They are nothing more than another cost on the income statement. But I hate it when it has to do with an acquisition that is still young. I'm talking about Coca-Cola (NYSE: KO) and a lawsuit brought against its VitaminWater asset.

According to this source, The Center for Science in the Public Interest doesn't like the way that Coke publicizes the health benefits of VitaminWater and is suing to make its point.

Words on the label of the bottles of the product irk the group, words like "defense" and "rescue." For those who have never ingested one of these drinks, these are the names of the drinks and are supposed to help consumers know which beverage to use in case you are feeling sick, or are feeling fatigued, etc.

According to an article on Reuters, Coca-Cola (NYSE: KO) is feeling the pressures of the flat domestic marketplace. COO Muhtar Kent, who will soon become the CEO, said in comments at a speaking event in Japan that Coke will be evaluating an acquisition strategy to grow the long-term prospects of its beverage business.

Now, this doesn't mean that a large purchase or merger is on the horizon, but it does mean that shareholders can expect, according to Kent, small, targeted asset buys. He did, however, specifically state that the company isn't giving up on organic growth, either, in its quest to expand its presence in beverages and beat back the ongoing threat of enemy number one, PepsiCo (NYSE: PEP).

He better not be giving up on it. Coke's stock recently retreated from its 52-week high of $65.59 to a price, as of noon today, of $56.37. The stock has done well over the last year, and this could be considered a normal consolidation. However, there has been a lot of buzz lately about Coke's domestic weakness.

PepsiCo's (NYSE: PEP) Gatorade brand has been struggling (WSJ subscription required) of late with competition from alternatives including Coca Cola's (NYSE: KO) Vitamin Water, a lower calorie, perhaps more-nutritious beverage. With the added pressure of aggressive pricing from Powerade, sales of Gatorade were down 2% in the last quarter, a sharp drop from the 29% increase in the prior year's quarter.

While PepsiCo expects Gatorade to rebound somewhat, its best days are probably behind it. People are realizing they just don't need that many calories in a drink, and Vitamin Water tastes just as good anyway.

The future of the Gatorade brand may very well rest squarely on the shoulders of G2, the company's soon-to-be launched lower-calorie alternative sports drink. Given the strength of the Gatorade brand, I like the company's chances with G2, and Coke may need to start worrying.

A piece in today's Wall Street Journal -- Should you sip your vitamins through a straw? -- raises an interesting point: There is little in the way of research to suggest that products like Coca Cola's (NYSE: KO) VitaminWater are a good way to absorb vitamins. But that hasn't stopped the market from exploding: "The explosion of nutrient-laced drinks reflects consumers' desire for more healthful choices than soda. These drinks' combined U.S. volume more than tripled from 2001 to 2006, according to the Beverage Marketing Corp., compared with 5% growth for the U.S. beverage industry over all."

Critics charge that some of these premium "healthy" beverages have a lot of calories (albeit fewer than soda), are expensive, and lack compelling evidence to back up suggestions that the products are actually that good for you.

But I don't think the average VitaminWater consumer is overly concerned with the assimilation of the vitamins. We drink VitaminWater because it tastes excellent, is more nutritious than soda, and is less artificial. I would guess that very few drinkers of these beverages are drinking them in lieu of vitamins: Most kids don't take a daily multivitamin like they should, so VitaminWater is better than nothing, right?

In any case, I don't think that VitaminWater's nutritional possibilities are a huge part of its appeal, and I don't think Coke shareholders should worry about the demise of that brand should studies emerge suggesting the product has little in the way of tangible health benefits.

Coca Cola's (NYSE: KO) purchase of Glaceau, makers of Vitaminwater, earned hip hop star 50 Cent 800 million times as much money as his name suggests he is worth.

It has been reported that 50 Cent will star in a commercial for the drinks, which will feature him conducting a symphony orchestra in a rendition of his hit "In da club."

I can't find information on how much 50 paid for his stake in the company, but it's safe to assume that he a made a massive return on investment here. He's not the first celebrity to make a fortune as an early investor in a company. Adult contemporary star Kenny G was one the original ten Starbucks investors.

But frankly, it's much more heartwarming to see 50 Cent making money, mainly because he's less annoying than Kenny G, although that's not much of an accomplishment.

In another indication that healthier premium beverages are supplanting soft drinks, Coca Cola (NYSE: KO) has agreed to pay Glaceau, the maker of Vitaminwater, for $4.2 billion in cash and stock.

While it's not exactly a cheap purchase, I think it makes a lot of sense for Coke. Vitaminwater has had huge growth of late, and that looks likely to continue. With sales of soft drinks flat or even declining, it needs something to drive revenue growth.

This should also be seen as good news for Berkshire Hathaway (NYSE: BRK.A), a major Coke shareholder. Chairman Warren Buffett is regularly seen drinking Cherry Coke, especially at annual meetings but, as he gets older and investors worry about who will succeed him, a switch to a more healthful, vitamin-filled, lower-calorie beverage could extend his tenure at the helm of Berkshire.

Shares of Coke were up on news of the deal, and the price tag could be used to assign a value to other next-generation beverage companies. It makes Hansen Natural (NASDAQ: HANS) look interesting, with its market cap of around $3.6 billion.

With soft drink sales stagnating as more health-conscious consumers switch to lower-calorie premium beverages, Coca-Cola (NYSE: KO) is looking for a piece of the action. After the February acquisition of Fuze, Coke is looking at privately-held beverage companies including Glaceau [subscription required], the maker of vitamin water and Arizona Teas, the best iced tea company out there.

While Coke has been delivering slow and reliable growth, Glaceau's has been extremely rapid of late, doubling its cases sold in 2006. Glaceau's price-tag of $2 billion might seem expensive, but it's the number one brand in a category that is expected to account for 22% of North American beverage sales over the next five years, making it second in volume only to bottled water.

With Hansen Natural (NASDAQ: HANS) and Jones Soda (NASDAQ: JSDA) valued at $3.5 billion and $681 million respectively, $2 billion for Vitamin Water might not be so bad.
