The remaining half could be purchased in 2012, Erste’s chief executive Andreas Treichl told a conference call.
The Austrian lender will sign separate agreements with each of the SIFs, he added.
Erste owns 69.4% in BCR. The bank announced recently it has reached an agreement in principle to buy another 24.12% stake in BCR from four of the five SIFs in exchange of EUR435 million in cash and stock.
SIF Muntenia has already signed a binding agreement to sell its 6% stake in BCR on October 13, the Austrian bank said.
SIF Moldova has not entered the agreement in principle, but it has called for a shareholder meeting November 26 to vote on Erste’s proposal.
