Amazon will also allow publishers to terminate contracts that contain specific clauses. "We are pleased to have reached an agreement with the European Commission," said Amazon spokesman Conor Sweeney. The commitments apply for five years to all e-books distributed by Amazon in Europe. Amazon could be fined up to 10% of global revenue if it goes back on its pledges. Separately, the commission continues to investigate whether Amazon's tax arrangements with Luxembourg gave the company an illegal advantage over competitors.
