Late last year it emerged that Larry Goodman's ABP was trying to buy the Allen family's 50pc stake in Slaney Foods, a joint venture with Northern Ireland's Linden Group.
Wexford-based Slaney has about 6pc of the Irish market and has big contracts with Lidl and McDonalds. Most recent financial statements showed turnmore than north of €200m, but it is likely to be far higher.
The Allens have other interests. They sold the Bewleys Hotel Group for €580m in 2008, just before the markets collapsed, in what may go down as the best-timed deal in history. They are also one of the largest private windfarm backers in the country, holding an 18pc stake in €150m valued Gaelectric.
There are also valuable German property holdings, including assets in Dusseldorf and Marl. Allen (77) is a serious collector of Eileen Gray furniture, and has restored her Brownswood family home in Wexford. One of the Irish designer's chairs sold for almost €22m.
