FRANKFURT (Reuters) - Influential proxy adviser Glass Lewis has recommended shareholders in Deutsche Boerse (>> Deutsche Boerse AG) vote against ratifying the actions of the management and supervisory board at the exchange's 2017 annual general meeting.

German companies typically ask their shareholders to approve the actions of their boards over the previous years at the annual shareholder meetings.

Glass Lewis said in a recommendation that shareholders may have concerns over the failed merger with the London Stock Exchange Group (>> London Stock Exchange Group Plc) and due to a pending investigation into CEO Carsten Kengeter over possible insider trading.

Kengeter denies the allegations, and has said that he and the company are cooperating fully with the public prosecutor.

Glass Lewis said shareholders may question management's performance in light of failing to make contingency plans for Britain's vote to leave the European Union in the merger documents.

On the investigation into Kengeter, it said it believed shareholders should be given the chance to vote on individual management board members rather than the board as whole.

"We are unaware of any specific evidence that Mr. Kengeter contravened insider trading regulations, but considering the ongoing nature and potential consequences of a negative outcome of investigations, we do not believe that shareholders can confidently determine whether approval of this proposal is in their best interests at this time," it wrote.

The recommendation was first reported by German daily Handelsblatt.

Deutsche Boerse declined to comment.

The AGM takes place on May 17.
