An account has found that Viacom, who used to be the parent company of Harmonix, owes the developer of the Rock Band music franchise no less than 383 million dollars (293.2 million Euro).
The expert was appointed jointly by the investors in the two companies as they seek to solve issues linked to their separation earlier during the year.
Recently Viacom had filled a lawsuit which claims that shareholders in Harmonix should be the ones paying about 131 million dollars (100.2 million Euro) that was awarded to them because of a miscalculation.
The sum of money is linked to bonuses that were set to be paid to shareholders based on the performance of the company.
Viacom and Harmonix parted ways earlier during 2011 and the development studio has since launched Dance Central 2, a rhythm game for the Kinect motion tracking system from Microsoft.
The company has also confirmed that it plans to deliver more Rock Band games, although no solid plans were revealed.
