Creditors of the insolvent Signa Holding of the Tyrolean investor René Benko have registered claims totaling a good 8.6 billion euros. The insolvency administrator of the umbrella company of the troubled real estate empire announced this on Monday.

Creditors' claims have increased by more than 70 percent since November. The vote on the restructuring plan is now scheduled for the end of April. Talks about the sale of Signa's stake in the New York Chrysler Building and to media are still ongoing.
