Key facts on Unilever merger proposal from Kraft Heinz
Unilever has rejected an initial $143bn merger offer from Kraft Heinz, which says it will continue working towards an agreement.
Here are some key facts on the potential tie-up:
* At $143bn, the deal represented an 18% premium on Unilever's closing share price on February 16, at 50 US dollars per share (£40.26).
*The deal would have been the biggest acquisition of a British company on record, based on offer value.
*On a global basis, it would have been the second-biggest deal behind Vodafone Airtouch's takeover of Germany's Mannesmann AG for 172 billion US dollars in 1999 (£138 billion).
*Unilever's leading brands include Marmite, PG Tips, Pot Noodle, St Ives, Vaseline, Lipton, Knorr, Ben & Jerry's, Brut, Magnum and Persil.
*Kraft Heinz brands include Philadelphia, Kool-Aid, Jell-O, Weight Watchers, Oscar Mayer, Velveeta, Planters and Maxwell House.
*Kraft Heinz has until March 17 to announce a firm intention to make an offer for Unilever, or confirm it will not make a formal bid.
*Kraft Heinz was born after Kraft Foods became the subject of 45 billion US dollar (£36.2 billion) takeover by HJ Heinz Co, owned by US business magnate Warren Buffett's Berkshire Hathaway and Brazilian investment firm 3G Capital, in 2015
