(A) YouTube pays the “primary” owner to simplify accounting.
(B) Revenue from claimed videos is allocated per territorial ownership.
(C) Whichever partner asserted ownership first gets paid.
(D) All revenue worldwide is equally divided among partners.
If a non-music asset is owned by multiple partners then the Revenue from claimed videos is allocated based on territorial ownership and the types of assets.
Revenue share is generally calculated according to the number of active monetized claims. For example, if a video is claimed by four non-music assets, all of which are set to monetize for a territory, the revenue is split four ways and then shared between each partner and Google.
This question is from the Check Your Knowledge section of the “Monetize assets with multi-party ownership” lesson from the YouTube Asset Monetization course.
