AIG will start marketing its shares to investors in May 2011, The Wall Street Journal reports. The company, which had earlier considered offering the shares in March, will launch the IPO after releasing its first-quarter results for 2011. The insurer, which is 92.1%-owned by the U.S. government, is planning a stock offering to start exiting federal ownership. AIG may raise about $20 billion through the ‘Re-IPO’ and may also offer some shares along with the government to raise cash to bolster its liquidity.
