A U.S. judge gave final approval today to Apple Inc.’s agreement to pay $450 million to resolve claims it harmed consumers by conspiring with five publishers to raise e-book prices.

During a hearing in Manhattan, U.S. District Judge Denise Cote approved what she called an “ unusual” accord. It calls for Apple to pay $400 million to as many as 23 million consumers (and $50 million to lawyers) if the company’s appeal of a ruling finding it liable for antitrust violations is unsuccessful.

The $400 million comes on top of earlier settlements with five publishers in the case.
