KKR said it has put forward a non-binding proposal offer to buy Assura, which values the London-Listed property business at 1.56 billion pounds ($1.97 billion).

The financial services company said Monday that it submitted four indicative non-binding proposals to the board of Assura over the last six months, with the intention of acquiring its entire issued share capital, but all but one were rejected unanimously by the board, KKR said.
