Consumer electronics giant Apple, which was unburdened by debt until this week, is relying on Hogan Lovells as the company undertakes its first bond sale in more than two decades to help finance a $100 billion capital return program to shareholders.

Apple priced an estimated $17 billion in bonds Tuesday as part of an offering to investors that Reuters reports is the largest nonbank bond deal in history. The Cupertino, California–based information technology and electronics company is seeking to return $100 billion in cash to shareholders by the end of 2015.
