While Apple has been found guilty of conspiring to fix e-book prices as it sought to launch its iBookstore alongside the iPad in early 2010, five publishers involved in the case have already agreed to settle the cases brought against them by state attorneys general and other class-action plaintiffs. Among the publishers, Hachette, HarperCollins, and Simon & Schuster had previously received court approval for their settlement agreements, and Macmillan and Penguin settlements are now proceeding through the approval phase. Customers who purchased Macmillan or Penguin e-books are now receiving emails informing them about the proposed settlement and their rights and responsibilities with respect to the agreement. Under the proposal, the Macmillan and Penguin settlement funds would be combined with previous amounts committed by the other publishers.
