Game of Thrones actors signed new contracts at 300,000 $ per episode?

Tyrion Lannister, Jon Snow, Cersei Lannister, Daenerys Targaryen and Jaime Lannister, or to put it differently, actors Peter Dinklage, Kit Harington, Lena Headey, Emilia Clarke and Nikolaj Coster-Waldau, have signed their new contracts with HBO. According to new agreements they will from now on earn 300,000 dollars per episode of the TV series Game of Thrones, said Daily Mail.
To clarify things a bit more, actress Lena Headey and actor Peter Dinklage have so far been earning 150,000 US dolars per episode. That means their earnings had doubled after they committed to the business cooperation with HBO for the seventh season to come.
Namely, after the HBO confirmed the shooting of the fifth and sixth season of ‘Game of Thrones’, five of these mentioned artists opened negotiations about their agreements with the TV station. According to Daily Mail over the past two months they have reached a consensus and signed new contracts.
