So, for $47.5 million, Jackson acquired the publishing rights to most of the Beatles songs. (The four songs issued on the Beatles' first two singles -- "Love Me Do" b/w "P.S. I Love You" and "Please Please Me" b/w "Ask Me Why" -- were not part of the package since they were published before the formation of Northern Songs, and the rights to those songs are now controlled by McCartney's MPL Communications. ATV also did not own the rights to George Harrison songs published after Harrison's songwriting contract with Northern Songs expired in 1968, but they did hold the rights to various other Lennon-McCartney songs not recorded by the Beatles.)
As a closing note, we should mention that Sony Corp. paid Michael Jackson $95 million in 1995 to merge ATV with Sony and form Sony/ATV Music Publishing, a 50-50 joint venture, so it's probably more correct to say that Jackson now owns half the rights to the Beatles catalog.
