MAJOR PAPERS:

• Warren Buffett's Berkshire Hathaway Inc (NYSE: BRK.A) and Mars are in talks to purchase Wm. Wrigley Jr. Co. (NYSE: WWY) for over $22B, the Wall Street Journal reported. An announcement may come as soon as today.
• The Royal Bank of Scotland Group Plc (NYSE: RBS) will start the integration of ABN Amro Holding's (NYSE: ABN) investment bank into its global markets division, the Financial Times reported. This process will most likely result in the paring of 7,000 jobs.

• According to the New York Post, IAC/InterActiveCorp. (NASDAQ: IACI) Chairman Barry Diller is expected to meet with his board this week to restart the process of breaking up his company into five separate pieces, sources said. At the same time, Diller and Liberty Media Corporation (NASDAQ: LMDIA) Chairman John Malone are continuing to talk about a deal that would trade one or more of IAC's assets for Liberty's ownership stake in IAC.
• The UK Times has learned that Numis Securities, the stockbroking group headed by Michael Spencer, is in "advanced talks" to buy the UK equities business of The Bear Stearns Companies Inc (NYSE: BSC). Numis may look to hire a team of 25 from Bear.

MOST NOTEWORTHY:

• Banc of America upgraded PetSmart (NASDAQ:PETM) to Buy from Neutral on valuation, as they believe the market is overly negative on the company's cyclicality.
  
• Keefe Bruyette upgraded shares of Marsh & McLennan (NYSE:MMC) to Outperform from Market Perform on increased confidence management will be able to improve margins.
  
• JP Morgan upgraded Pinnacle Airlines (NASDAQ:PNCL) to Overweight from Underweight citing the company's FCF and contract certainty.

• Hasbro (NYSE:HAS) was upgraded to Buy from Hold at Needham.
  
• Calyon raised Airtran Holdings (AAI) to Add from Neutral.
  
• Liberty Entertainment (LMDIA) was raised at Merrill to Buy from Neutral.

Barry Diller has won his dispute with John Malone. Malone's Liberty Media (NASDAQ: LCAPA) owns a a large piece of the company that Diller runs, IAC/Interactive (NASDAQ: IACI). Diller has the right to vote those shares under a long-standing agreement.

Diller has decided to break IACI into five companies because the businesses in the firm do not have significant relationships to one another. Malone wanted to block the break-up and filed suit in court.

According to MarketWatch, "Vice Chancellor Stephen Lamb ruled Friday that "Liberty has failed to demonstrate that Diller has breached or threatened to breach any contractual duty he owes to Liberty," according to Lamb's 78-page opinion."

Diller can now complete his plans.

That leaves open the question of whether IACI is worth more in pieces than it is as a conglomerate. The firm's stock trades at $20, near its 52-week low and down from the period high of over $39. Some of the company's divisions, especially Lending Tree and HSN had tough years in 2007. These would get very low valuations as independent operations and might not make up for the value of more attractive operations like Ask.com

Diller may have gotten his way, but it is not clear that it will help shareholders.
