British telecom company Vodafone Group PLC has agreed on a so-called domination agreement with Kabel Deutschland. Vodafone's move came three months after its €7.7 billion ($10.5 billion) acquisition of Germany's largest cable company went through. 

Forbes defines a domination agreement as a type of takeover structure used in Germany by acquirers who want to gain full control of the company without controlling all the shares.

According to a report by Reuters, Vodafone will offer the remaining shareholders of Kabel Deutschland €84.53 for each of their shares. This is slightly more than the €84.50 per share it had offered in its takeover bid in June. 

Some activist shareholders, including Paul Singer's hedge fund Elliott Asset Management, had increased their holdings in Kabel Deutschland. The said shareholders are hoping to squeeze out a better offer following the takeover, the report said. 

Investors in two other German companies, utility Mainova AG and HVB Real Estate Bank, earlier this year used this tactic successfully in other deals to get more for their shares, Reuters said.
