"Points" is the percentage of the money earned and where it goes to for a major label distributed recording (one point equals one percent, i think):
A major label usually takes all recoupable money (money used on the artist to record, mix, produce, promote, packaging, etc.)
It comes right out of the artist's royalty check, so when its all said and done, after you make a gold record, the label will turn around like an ex wife and f--- you over. Sometimes, young artists who sell mad records will even OWE a record company into their second and third albums, depending on what their contract was to begin with. Usually a record company will only sign you with a bunk contract where they have nothing to lose really and then when an artist proves to be worthy, lawyers step in and renegotiate a new contract.
I hope thats clear enough, if not, Go to your library and borrow "Inside the Music Indutry" by Michael Fink, or theres a really great article by Steve Albini called "The problem with music" (the original print copy had a front cover picture of a gun placed on the unsuspecting head of a new artist with the caption - some of your friends are already this f--ked...)
I invite EVERYONE to read this inciteful article. It has an average breakdown on why new artists should think twice before signing:
