Chemical giant DuPont Co on Monday upped its offer for the 24 per cent of DuPont Canada it does not already own.

The Delaware-based company lifted its offer to C$21.75 per DuPont Canada share, for a total of C$1.46 billion (US$1.07bn), up from its original bid in March of C$21 a share, or C$1.4bn (US$1.02bn) for the outstanding 67 million shares of DuPont Canada.

The company added it hopes to complete the acquisition before the end of next month.
