In a vote at the bank's annual general meeting, shareholders backed the re-election of supervisory board chairman Paul Achleitner to a second five-year term. They also endorsed the management and supervisory boards' actions of 2016.

Some larger shareholders, like Union Investment, had urged shareholders to vote against authorizing management to write what they called another blank check after hefty capital increases in recent years.

But in the end shareholders authorized a measure that could allow the bank to issue new shares with subscription rights by almost 39 percent of over the next five years.

Shareholders rebuffed a move for an independent audit to probe management's role handling recent scandals that include the manipulation of Libor and Russian trades.
