The final count of Celanese shareholders' votes has given Blackstone an 83.6% holding in the company, vindicating the buy-out firm's decision last month to reduce its threshold for acceptances from 85% to 75%.

Blackstone, advised by Morgan Stanley, said it would now give minority shareholders the opportunity to tender their shares at the same offer price of €32.50 a share. The offer values the company at €3.1bn ($3.8bn), making the transaction Germany's largest ever take-private.
