Viacom has sued stockholders of former subsidiary Harmonix for $131 million.
According to the Hollywood Reporter, Viacom is seeking to recover $131,827,980 of the $149,770,149 paid to the Rock Band maker for the franchise's performance, claiming in its lawsuit that earnings payments were miscalculated.
The Harmonix shareholders dispute that they owe any refund. In fact, they sued Viacom last December, accusing the firm of attempting to wriggle out of honouring performance-related bonuses.
Harmonix was acquired by Viacom in 2006, but was sold at a massive loss last year.
