US chewing gum manufacturer Wrigley has announced that its chief executive plans to sell up to US$43.6m worth of common stock held in trusts over the next three months.

The move is aimed at diversifying the Wrigley family’s holdings, according to a regulatory filing by the company.

The shares represent a maximum of 2.3% of CEO William Wrigley Jr’s ownership of common stock in the company, reported Reuters.
