When is an IPO considered failure? 
Just skimming through the Wikipedia article on airberlin, I notice there is more to the story than simply "airberlin's IPO failed, so they postponed it and did it anyways." 3 points to keep in mind about IPOs:  1) An IPO is the mechanism for taking a private company and setting it up for shares to be owned by "the public".  2) The process of selling shares to the public often allows original owners and/or early investors to "cash out". Most countries (including member nations of the EU) limit some transactions like pre-IPO companies to "accredited investors".  3) Selling shares to the public also can allow the company to access more funds for growth. This is particularly important in a capital-intensive business like an airline; new B737-MAX costs >$110M. New A320neo costs >$105M USD.  Ultimately, the question of a successful IPO depends on how you define success. Initially, there was a lot of concern that the IPO was set up with too much focus on goal #2... allowing the management & owners to cash out.  It looks like the first approach was not meeting good opinions in the market during 2006. A major concern was that the initial approach focused on management only cashing out its shares and no money actually going to the company to support its future.  The investment bankers restructured the IPO, including the issuance of more new shares so that more $ could end up in the company's accounts, not just in the accounts of the management.  If anything, it's still a pretty successful IPO given that the shares were successfully listed, the company collected the money it needed to invest and grow, and the management still cashed out.
