This morning's New York Times reports that Citigroup Inc.'s (NYSE: C) Todd Thomson was ousted from his role as head of global wealth management yesterday.

Thomson, a former Bain consultant and Citigroup CFO who in 2005 touted that role as "the conscience of a company", was hired from General Electric Company (NYSE: GE) by former CEO Sanford Weill. According to the New York Times, Thomson had disagreements with Citigroup CEO, Chuck Prince, over acquisitions and business strategy.

But the kicker was that Thomson arranged to make Citigroup's corporate jet available to GE's NBC Universal's CNBC reporter, Maria Bartiromo, so she could fly to Asia. Beyond a DealBreaker Blind Item suggesting that Bartiromo may have played a part in Thomson's leaving his wife and family, this event raises troubling governance questions:

• What did Prince know about this and when did he know it?
• Are there other governance issues at Citigroup that Prince has yet to clean up?
• Why can't CNBC arrange transportation for its employees on its own?
• Doesn't this cozy relationship with Citigroup compromise the objectivity of Bartiromo's reporting on Citigroup?
• Have other companies arranged such travel for Bartiromo or other CNBC reporters?

While CNBC noted that it paid for the plane trip, it looks like CNBC and Citigroup have some more explaining to do.

Peter Cohan is President of Peter S. Cohan & Associates, a management consulting and venture capital firm, a Professor of Management at Babson College, and editor of The Cohan Letter. He has appeared as a guest on CNBC and owns Citigroup and GE stock.

In the new issue of Business Week, Maria Bartiromo conducts an excellent interview with Carlyle Group co-founder David Rubenstein about his outlook for private equity in 2007.

Rubenstein predicts more money going into emerging markets, and he said the Carlyle Group will double its investment in Asia this year. He is also weary of increased government regulation of private equity groups, and provided a great quote: "The Declaration of Independence says we're supposed to pursue happiness, but when people are too happy, the government doesn't like it."

If other private equity groups follow Carlyle's lead of doubling up on Asia this year, emerging markets could see a buyout-fueled bull market similar to what the United States saw in 2006. I suspect that exchange-traded funds could be the best way to make that bet.
