TRW Automotive Holdings Corp., one of the world’s leading automotive suppliers, confirmed on Thursday that it has received a non-binding takeover offer.

A source close to the matter told Bloomberg News that the acquisition proposal came from Germany’s ZF Friedrichshafen AG, but TRW did not identify the company in its statement. A representative from the German firm, which produces auto-transmission and steering systems, was not immediately available for comment, according to The Wall Street Journal.
