Bayer AG made an unsolicited takeover offer for Monsanto in May, aiming to create the world's biggest agricultural supplier.

Monsanto turned down the offer as "incomplete and financially inadequate," but said it was open to further talks.

The loan facility, which have a maturity of up to a year, will have around 0.5 percent interest rate for the first half.

"As a matter of principle, we do not comment on any market rumors," Bayer spokesman Michael Preuss said on Thursday.

The banks were not immediately available for comments.
