A Carlyle Group IPO should catch the attention of the media and many investors. In the past the private equity firm has come under scrutiny from the left because the bin Laden family once owned a stake, ex President George H.W. Bush, and former Secretary of State James Baker also once served as advisors. Politics aside, the Carlyle Group is good at what they do. The L.P. posted an economic net income of over $1 billion in 2010.
