National Bank says 3-year business plan not valid

ATHENS, June 26 (Reuters) - National Bank (NBGr.AT), Greece's biggest lender, said on Friday it dropped its 2007-2009 business plan because it didn't take into account the ongoing global economic crisis.

"Due to the adverse global financial conditions and the continuing instability prevailing in the markets... the assumptions on which it 2007-2009, three-year business plan was prepared have changed and are no longer relevant," the lender said in a bourse filing. (Reporting by Harry Papachristou)
