During the drawn-out damages portion of the US suit, events played into Harrison's hands when Klein's ABKCO Industries purchased the copyright to "He's So Fine", and with it all litigation claims, after which Klein proceeded to negotiate sale of the song to Harrison. On 19 February 1981, the court decided that, due to Klein's duplicity in the case, Harrison would only have to pay ABKCO $587,000 instead of the $1.6 million award and would also receive the rights to "He's So Fine" – $587,000 being the amount Klein had paid Bright Tunes for the song in 1978. The court ruled that Klein's actions had been in breach of the fiduciary duty owed to Harrison, a duty that continued "even after the principal–agent relationship ended".
