For example, in the United States, class lawsuits sometimes bind all class members with a low settlement. These "coupon settlements" (which usually allow the plaintiffs to receive a small benefit such as a small check or a coupon for future services or products with the defendant company) are a way for a defendant to forestall major liability by precluding many people from litigating their claims separately, to recover reasonable compensation for the damages. However, existing law requires judicial approval of all class-action settlements, and in most cases class members are given a chance to opt out of class settlement, though class members, despite opt-out notices, may be unaware of their right to opt out because they did not receive the notice, did not read it, or did not understand it.
