Syngenta’s independent directors will ensure its investment-grade rating

The deal, pending regulatory approvals, has raised questions on its financing, and Syngenta’s future corporate governance, given the opaque nature of Chinese state-owned enterprises. Four independent directors will be appointed to the board, and approvals from at least two of them will be required to approve any significant changes. ChemChina last week made a $43 billion bid for Syngenta, in China’s biggest overseas takeover, aimed at improving food production in the world’s largest agricultural market.
