On 7 June 2010 nine out of eleven votes were cast by Karstadt's board of creditors in favour of the Berggruen Holding – although the vote was subject to the closing conditions that the Highstreet consortium waived its demand for rental payments. Berggruen signed the purchase contract – primarily conditional upon an agreement with the principal landlord Highstreet – on 8 June 2010. €70 million was named as the purchase and investment price with a further €240 million to be invested in the following three years, for which Berggruen required no external capital. On 30 June 2010 the Federal Cartel Office approved the takeover of the department store chain. After tough negotiations, agreement with the Highstreet consortium regarding rental payments was reached in early September 2010.
