Mr. Spacey was once the centerpiece of the hit Netflix series, which ran for six seasons between 2013 and 2018.
While the sixth and final season was being filmed in 2017, the actor Anthony Rapp accused Mr. Spacey of making a sexual advance toward him in 1986, when Mr. Rapp was 14.
In the arbitration, MRC argued that Mr. Spacey’s behavior caused the studio to lose millions of dollars because it had already spent time and money in developing, writing and shooting the final season.
