Groupon Inc. (GRPN) Chairman Eric Lefkofsky transfered 18.7 million of the company’s shares to early investors, consultants and advisers, according to regulatory filings and a spokesman for the executive.

Most of the shares were transfered from a company called 600 West Groupon LLC, which is managed by a company co-owned by Lefkofsky and his wife, according to a filing with the U.S. Securities and Exchange Commission.

“Most of that stock is now being distributed to its beneficiaries and Eric is distributing the stock he personally owns in that LLC to his family’s charitable foundation,” said Charles Sipkins, a spokesman for Lefkofsky.
