Procter & Gamble Co. (NYSE: PG) currently owns dozens of brands, many of which are household names. From Pampers to Pringles, Crest to Cover Girl, the consumer-products giant has a foothold in many industries, and its 2005 purchase of Gillette merely added to this list. (For a summary of the company's current product lines, click here.)

Now, there is some speculation on Wall Street as to whether Procter & Gamble will sell off some of its brands in an effort to streamline operations and return cash back to company shareholders. While it is pure conjecture at this point -- company officials have not said publicly that they are considering spinning off any brands -- Lehman Brothers analyst Lauren Lieberman told The New York Times that she suspects "there has been an active dialogue within P&G about if, when, and what pieces of its portfolio should be pruned via sale or spin."

Ms. Lieberman ran the numbers, and it appears as though the most likely brands for sale consideration are Duracell, Braun, Folgers (and other coffee), and Pringles (along with other snack lines). The company's pet-food business (which includes the Iams brand) could also be put on the auction block.

Duracell could fetch as much as $4.1 billion (in after-tax proceeds) at auction, while Braun could attract up to $1.5 billion. The snacks and coffee units are both valued around $4.1 billion, while the pet-food business could be sold for $2 billion, Ms. Lieberman said.
