Software developer SunGard Data Systems has filed for an initial public offering, about a decade after a group of private equity firms acquired it in an $11 billion deal that helped usher in a wave of megabuyouts before the financial crisis.

SunGard's private equity owners-Bain Capital, Blackstone Group, Goldman Sachs's private equity arm, KKR, Providence Equity Partners, Silver Lake and TPG-will continue to own a majority voting power, according to a filing with the US Securities and Exchange Commission.
