envisioned fees such as those that have resulted from mass tort litigation.1
Three separate parties in this heart-valve implant class action appeal district court orders relating to an award of fees to class and special counsel. Intervenors, who are absent class members, appeal the district court’s denial of a motion to compel discovery of class counsel’s fee-sharing agreements with special counsel. Class counsel cross-appeals the district court’s award of attorneys’ fees as insufficient. The Pennsylvania Class Objectors, another group of claimants composed of Elizabeth Ridgeway, Rosemary Grunsby, and Fred Grunsby, as well as the law firms of Sidkoff, Pineus & Green, P.C., and Wap-ner, Newman & Wigrizer, also appeal from the district court’s order awarding attorneys’ fees and expenses to class and special counsel'.
These appeals arise out of a worldwide class-action settlement involving an allegedly defective heart valve implant. In 1992, a settlement agreement was reached between class counsel and the defendants. Although numerous objections to that settlement were filed, most of the objections were withdrawn before the district court approved the settlement. Prior to the district court’s approval of the settlement, class counsel filed a motion to have several of the formerly objecting attorneys appointed as special counsel to class counsel. The district court approved the appointment, and the newly appointed special counsel subsequently entered into fee-sharing agreements with class counsel. The intervenors brought a motion to compel discovery of the fee-sharing agreements that remain undisclosed. The district court denied the motion.
In the meantime, class counsel filed a fee application in district court seeking $33 million in attorneys’ fees. After removing himself from the attorneys’ fees portion of the case, the original judge transferred the case to an out-of-circuit senior district judge. On March 1, 1996, after conducting a hearing on the attorneys’ fees issue, the court awarded class and special counsel $10.25 million in attorneys’ fees and $476,938.06 in expenses from the settlement’s medical and psychological, patient benefit, and spousal compensation funds to be split among the attorneys on a pro rata basis. Bowling v. Pfizer, 922 F.Supp. 1261 (S.D.Ohio 1996), amended by 927 F.Supp. 1036 (S.D.Ohio 1996). The court also recognized class and special counsels’ continuing obligations to the class and ordered that those attorneys be permitted in the future to apply annually for additional fees and expenses in an amount not to exceed 10% of the annual $6.25 million payments to be made to the common funds by Pfizer and Shiley. The district court also granted $105,-037.46 in fees and expenses to Public Citizen, Inc., but denied all other fee and expense requests.
Class and special counsel subsequently filed a motion to reconsider, alter, and amend the district court judgment. In an order entered on May 28, 1996, the district court denied that motion in part, but did increase the award of expenses to the attorneys by $75,344.10.

We review a district court’s award or denial of attorneys’ fees for an abuse of discretion. Cramblit v. Fikse, 33 F.3d 633, 634 (6th Cir.1994). It is within the district court’s discretion to determine the “appropriate method for calculating attorney’s fees in light of the unique characteristics of class actions in general, and of the unique circumstances of the actual cases before them.” Rawlings v. Prudential-Bache Properties, Inc., 9 F.3d 513, 516 (6th Cir.1993). The district court’s award of attorneys’ fees in common fund cases need only be “reasonable under the circumstances.” Id. The Pennsylvania class objectors and class counsel separately contest the district court’s award of attorneys’ fees. After careful scrutiny of the alleged errors referenced by class counsel, we find that the district court did not abuse its discretion in its award of attorneys’ fees.
