In determining the method by which notice is to be given, the court shall considerI. the cost of giving notice by each method consideredII. the resources of the parties andIII. the stake of each represented member of the class, and the likelihood that significant numbers of represented members would desire to exclude themselves from the class or to appear individually, which may be determined, in the court's discretion, by sending notice to a random sample of the class.(d)I. Preliminary determination of expenses of notification. Unless the court orders otherwise, the plaintiff shall bear the expense of notification. The court may, if justice requires, require that the defendant bear the expense of notification, or may require each of them to bear a part of the expense in proportion to the likelihood that each will prevail upon the merits.
