Navios Maritime Acquisition Corp (NYSE: NNA) is a blank-check company that completed its initial public offering in 2008, targeting the global maritime and tanker shipping sector. The SPAC was sponsored by affiliates of Navios Maritime Holdings Inc., the international shipping company led by chairwoman and chief executive Angeliki Frangou. NNA completed a business combination to acquire a fleet of crude oil and petroleum product tankers, transitioning from a shell vehicle into an operating tanker company and filing as a foreign private issuer with the SEC. The October 2011 Form 6-K filing reflects routine interim disclosure obligations under that foreign-issuer reporting framework.
