U.S. companies have already raised $16.8 billion through initial public offerings so far this year, a pace not seen since the start of the financial crisis more than five years ago, according to The Wall Street Journal. Not surprisingly, several Am Law 100 firms are reaping the benefits from the flood in new filings.

The Am Law Daily reported earlier this year on how some firms were preparing themselves for a rebound in U.S. IPOs in 2013, which has so far yielded large listings for the likes of Evertec, Norwegian Cruise Line, SeaWorld Entertainment, Taylor Morrison Home, West Corp., and Zoetis.

Still in the pipeline are prospective IPOs such as cosmetics maker Coty (advised by Gibson, Dunn & Crutcher), Apollo Management–backed women’s accessories retailer Claire’s (Morgan, Lewis & Bockius), and KPS Capital Partners’s Global Brass and Copper (Paul, Weiss, Rifkind, Wharton & Garrison). Meanwhile, billionaire Thomas Barrack Jr.’s home rental spin-off Colony American Homes is being advised by Clifford Chance as it seeks to raise up to $100 million in an IPO. (Former Clifford Chance partner Ronald Sanders serves as general counsel for Colony American.)

Another company being openly discussed as likely to tap into the capital markets is Twitter, the global communications platform founded in 2006. Bloomberg reports that Twitter was recently valued at $10 billion and the San Francisco–based company has fueled speculation this month that an IPO might be imminent by hiring a former executive from Morgan Stanley. Twitter also recently secured a multimillion-dollar advertising deal with Starcom Media Vest Group and the company has been pursuing content-sharing agreements with NBC and Viacom.

Wilson Sonsini Goodrich & Rosati alum Alexander Macgillivray serves as Twitter’s general counsel. Macgillivray, who left Google in 2009 to join Twitter, did not respond to a request for comment. (SEC rules on "quiet periods" generally bar lawyers and other professional advisers from engaging in pre–IPO chatter.) Last year Twitter also hired former Google in-house lawyer and ex–Perkins Coie partner Nicole Wong, whose name emerged in news reports this month as a potential candidate to become the Obama administration’s first chief privacy officer.

Twitter’s rumored IPO aside, the spate of new public listings over the past few weeks has been dominated by dividend-paying companies such as real estate investment trusts, according to The Deal. Greenwich, Connecticut–based Renaissance Capital, which tracks IPOs, notes that the North American market ranks first globally in terms of active deals and proceeds.
