On the eve of the Blackstone Group’s much anticipated initial public offering (IPO), a Wall Street portfolio manager contemplates his commitment to purchase 20,000 units at $31.00 each. As one of the largest IPOs in recent history and the first major PE fund to go public in the United States, the offering had stirred up significant media and congressional interest, some of which was potentially damaging for the PE industry. Even taking the uncertainty of the tax law into consideration, the manager thought the market would respond positively to Blackstone’s newly traded units. But there were still risks to consider.
