The players in Facebook are elusive. Since it is a private company, it is not required to disclose its partners. Once and a while we learn about an individual or company that has a piece of the company.

Not only is it difficult to find out who owns a stake in Facebook, it is equally difficult to ascertain the value of the company. The numbers keep going up and up. For example, Microsoft (MSFT) invested $240 million when the company was valued at $15 billion.

Interpublic (INPGP), the advertising conglomerate, bought 1/2% of Facebook for $5 million, in 2006. As the value of the company went up, so did Interpublic's investment. When the Facebook investment appreciated, Interpublic was forced to disclose the information to the SEC, as reported in the Financial Times.

MOST NOTEWORTHY: The U.S. Retail Hardlines Sector, the BioFuels Sector, Interpublic Group and Omnicom Group were today's noteworthy initiations:

• Lehman initiated the Retail Hardlines Sector with a Neutral. The firm initiated coverage of Home Depot (NYSE: HD) and Lowe's (NYSE: LOW) with Overweight ratings and Best Buy (NYSE: BBY), Bed Bath & Beyond (NASDAQ: BBBY) and Williams Sonoma (NYSE: WSM) with Equal Weight ratings.
  
• Oppenheimer initiated Aventine Renewable (NYSE: AVR), Pacific Ethanol (NASDAQ: PEIX) and VeraSun Energy (NYSE: VSE) with Perform ratings. The firm is cautious on the industry due to higher feedstock costs.
  
• UBS initiated Interpublic Group (NYSE: IPG) and Omnicom Group (NYSE:OMC) with Buy ratings and an $11 target and $62 target, respectively. The firm views valuation as attractive.

OTHER INITIATIONS:

• Morgan Stanley assumed coverage of International Flavors (NYSE: IFF) with an Overweight rating.
  
• Wachovia initiated CGI Group (NYSE: GIB) with a Market Perform rating.
  
• Leap Wireless (LEAP) was initiated at RBC Capital with a Sector Perform rating and $55 target.

Dell (NASDAQ: DELL) is set to trust most of its advertising and marketing to WPP, the big ad agency conglomerate based in the UK. The move is a blow to Interpublic (NYSE: IPG), which had been working to get the account.

The relationship between the PC company and ad agency will be set up as a partnership. The Wall Street Journal writes, "Sir Martin Sorrell, chief executive of WPP, said it would take WPP and Dell roughly three to six months to build the new firm, which will start with about 1,000 employees. Dell management around the world will have to give up local ad ties."

But, the manner in which the deal was cut says a lot about what is wrong with Dell. Picking the new agency took almost three quarters. And it will take almost another quarter to set it up. That means that the PC company's marketing plans will have been in flux for almost a year. With all of Dell's problems, the company can hardly afford to spread significant decisions over such a long period.

It is good that Dell has finally made a decision, but it is very bad that it does not have processes in place to speed getting to the finish line on such critical problems.

Analyst summaries provided by TheFlyOnTheWall.com (subscription required).

If Google, Inc. (NASDAQ:GOOG) has its way, its program for buying newspaper ads and radio time will automate a process that is now being handled by ad agencies. The process is fairly labor intensive. At least for now.

As Google moves into the offline ad buying business, it is being followed by eBay, Inc. (NASDAQ:EBAY) and Yahoo!, Inc. (NASDAQ:YHOO). EBay has set up a TV buying service and Yahoo! recently announced an online ad deal with 176 newspapers.

All of this could make life for public ad agency giants like Interpublic Group of Companies, Inc. (NYSE:IPG), Omnicom Group, Inc. (NYSE:OMC) and WPP Group ADS (NASDAQ:WPPGY) a little tough. Selling advertising through online auction systems takes away a key ad agency function -- selected ad buying media for large marketing clients.

Some large advertisers are already jumping over the fence.
