*615 OPINION
We consider in this appeal whether the federal courts must incorporate state law as the federal rule of decision with respect tq the calculation of prejudgment interest and attorney fees awarded to prevailing plaintiffs in a civil enforcement-action under the Employee Retirement Income Security Act (“ERISA”), 29 U.S.C. § 1132. The plaintiffs argue that the district court erred when it rejected their request that the court calculate prejudgment interest and reasonable attorney fees in accordance with Michigan law. Because prejudgment interest and attorney fee awards are not issues primarily of state concern, and because application of Michigan law in this case would frustrate ERISA’s remedial scheme, we hold that the district court was not required to look to state law. Accordingly, we affirm the district court’s calculation of the prejudgment interest and attorney fees awarded in this matter. ,
I. FACTS AND PROCEDURAL HISTORY
The long and tortuous history of this case began in 1984, when the plaintiffs filed suit under ERISA against the defendant, Uniroyal Pension Plan, Board of Benefits and Awards (“Uniroyal”), for disability retirement benefits owed them under the Uniroyal Retirement Plan (the “Plan”).
1
The plaintiffs were employees at the now-defunct Uniroyal Tire Plant in Detroit, which was closed in July of 1981. After the plant’s closing, the plaintiffs applied for disability pension benefits under the Plan. Uniroyal denied their applications, and this litigation ensued. In 1990, the district court granted summary judgment in favor of the plaintiffs on their claim for disability benefits under the Plan. J.A. at 88-104 (Dist. Ct. Order 5/29/90); 105-07 (Dist. Ct. Order 8/20/90). The district court also granted the plaintiffs’ request for attorney fees under ERISA, 29 U.S.C. § 1132(g)(1), as well as their request for prejudgment interest, after determining that the defendant had engaged in a pattern of bad faith, “as evidenced by (1) the imposition of sanctions upon the Defendant, for having misled [the district court] and the arbitrator, (2) wasting the time of the Plaintiffs and the arbitrator by objecting to arbitration after stipulating to it before this Court, and (3) denying the Plaintiffs [sic] applications for pensions because of ‘arbitrary and capricious’ reasons when there was no medical dispute that they were entitled to disability benefits.” J.A. at 106-07 (Dist. Ct. Order 8/20/90).
Although.
the district court had previously sanctioned the defendant, it declined to levy additional Rule 11 sanctions against the defendant after concluding that additional sanctions were unwarranted.
See id.
The Sixth Circuit affirmed the district court’s order on appeal, including the decision to award attorney fees and prejudgment interest.
See Kennedy v. Uniroyal Pension Plan,
Nos. 90-1705/1983/2048/2110,
After the Sixth Circuit affirmed the order granting the plaintiffs’ motion for summary judgment, attorney fees, and prejudgment interest, the district court commenced proceedings in order to calculate the amount of prejudgment interest and attorney fees to which the plaintiffs were entitled. ERISA does not prescribe the applicable prejudgment interest rate or the method by which the district courts should calculate reasonable attorney fees. The district court rejected the plaintiffs’ invitation to look to state law for the applicable prejudgment interest rate and the calculation of attorney fees. Relying on the recommendations of the magistrate judge, the district court awarded the plaintiffs reasonable attorney fees plus post-judgment interest. The district court adopted the defendant’s calculation of the prejudgment interest on the benefits wrongly withheld from the plaintiffs, which utilized a 9% annual interest rate. Declining to award the plaintiffs their future monthly benefits in a lump-sum, the district court instead directed Uniroyal to continue payment of monthly pensions as they became düe in accordance with the Plan. The district court also declined to award the plaintiffs prejudgment interest on the present value of future benefits. J.A. *616 at 67-68 (Am. Supp. Post-J. Order at 3-4). This appeal ensued.
II. ANALYSIS
On appeal, the plaintiffs challenge the district court’s calculations of prejudgment interest and reasonable attorney fees. Specifically, the plaintiffs assert that because ERISA is silent with respect to prejudgment interest awards and the method by which the federal courts should calculate attorney fees, the federal courts must look to state law in determining the applicable prejudgment interest rate and the method by which to calculate reasonable attorney fees. We disagree, and hold that the district court was not required to incorporate state law as the federal rule of decision on these matters.
A. Prejudgment Interest
Although ERISA does not mandate the award of prejudgment interest to prevailing plan participants, we have long recognized that the district court may do so at its discretion in accordance with general equitable principles.

See Wells v. United States Steel, Carnegie Pension Fund,
Although any common law rule necessary to effectuate a federal statutory right is inherently federal in character, “[i]t does not follow ... that the content of such a rule must be wholly the product of a federal court’s own devising.”
Kamen v. Kemper Fin. Servs., Inc.,
Our review of Supreme Court precedent suggests a strong inclination to adopt state law as the federal rule of decision when the federal statute is silent on a matter traditionally of state concern. This inclination, grounded in federalism, reflects the principle that the federal courts may not intrude into the traditional domains of the states absent authorization from Congress.

Even assuming that the calculation of prejudgment interest involves an area primarily of state concern, incorporation of state standards in the calculation of prejudgment interest could frustrate ERISA’s remedial scheme. Plaintiffs ostensibly brought their original ERISA causes of action under 29 U.S.C § 1132(a)(1)(B),
3
which is one of “six carefully integrated civil enforcement provisions found in [§ 1132(a)],”
Massachusetts Mut. Life Ins. Co. v. Russell,
Although prejudgment interest is typically not punitive, an excessive prejudgment interest rate would overcompensate an ERISA plaintiff, thereby transforming the award of prejudgment interest from a compensatory damage award to a punitive one in contravention of ERISA’s remedial goal of simply placing the plaintiff in the position he or she would have occupied but for the defendant’s wrongdoing.
See Hizer v. General Motors Corp., Allison Gas Turbine Div.,
Because we conclude that the federal courts need not incorporate state law as the federal common law rule for the applicable prejudgment interest rate, we reaffirm our earlier decisions leaving the determination of the prejudgment interest rate within the sound discretion of the district court.
See, e.g., EEOC v. Wooster Brush Co. Employees Relief Ass’n,
*620
Relying on Mich. Comp. Laws Ann. § 600.6013, the plaintiffs also assert that the district court erred in not awarding prejudgment interest on the present value of future benefits due the plaintiffs under the Plan. As explained previously, prejudgment interest awards under ERISA serve as compensation to a plaintiff for the lost use of money wrongly withheld; such awards may not penalize the defendant.
See Tiemeyer,
B. Attorney Fees
We review the award of attorney fees under ERISA for an abuse of discretion.

way,
“The presumption that state law should be incorporated into federal common law is particularly strong in areas in which private parties have entered legal relationships with the expectation that their rights and obligations would be governed by state-law standards.”
Kamen,
Finally, none of the Michigan cases relied upon by the plaintiffs supports stacking attorney fees in the manner advocated by the plaintiffs. Michigan precedent permits the recovery of attorney fees under more than one statutory provision or rule in order that the purpose of each statute or rule may be realized.
See, e.g., Howard v. Canteen Corp.,
III. CONCLUSION
For the reasons explained above, we AFFIRM the district court’s awards of prejudgment interest and attorney fees as set forth in its December 8, 1994 postjudgment order.
Notes
. Plaintiffs Kennedy, Ford, and Aiken filed suit against the Board on September 4, 1984. Plaintiff Burrell was added as a plaintiff in January 1985.
. By federal statute, courts allow postjudgment interest on all money judgments. 28 U.S.C. § 1961 provides that postjudgment interest
shall be calculated from the date of the entry of the judgment, at a rate equal to the coupon issue yield equivalent (as determined by the Secretary of the Treasury) of the average accepted auction price for the last auction of fifty-two week United States Treasury bills settled immediately prior to the date of the judgment.
. Plaintiffs do not specify in their complaint on which subsection of § 1132 they based their claims. Each plaintiff in'the amended complaint appears to request relief under § 1132(a)(1)(B), which permits civil actions by an employee "to recover benefits due to him under the terms of his plan, to enforce his rights under the terms of the plan, or to clarify his rights to future benefits under the terms of the plan....” The district judge later awarded attorney fees and prejudgment interest as a matter of discretion. J.A. at 100, 106-07 (Dist. Ct. Orders 5/29/90 & 8/20/90). In their complaint, plaintiffs also requested damages in excess of $10,000 per plaintiff for emotional distress. The district court dismissed the plaintiffs’ emotional distress claims, J.A. at 101 (Dist. Ct. Order 5/29/90); therefore this court need not determine under which provision of § 1132 plaintiffs originally purported to support .their claim for emotional distress.
. One can interpret the Supreme Court's dicta in
Ingersoll-Rand Co. v. McClendon,
We do not interpret these statements to mean that the remedies which the plaintiff in Inger-soll-Rand was seeking. — future lost wages, mental anguish and punitive damages — are necessarily available under ERISA § 502(a). The Supreme Court was stating that federal law provides relief for ERISA actions other than those that seek to recover pension benefits, such as the plaintiff's cause of action for wrongful termination. The Supreme Court is not holding that the specific remedies this plaintiff had sought under state law are necessarily the remedies that will be afforded him should he be granted relief under ERISA § 502.
McRae v. Seafarers' Welfare Plan,
. None of the cases relied upon by the plaintiffs supports their position, that the federal courts must adopt the prejudgment interest rate prescribed by state law. In
Smith v. American International Life Assurance Co. of New York,
. After the plaintiffs concurred in Uniroyal's calculation of the prejudgment interest award, J.A. at'271-73 (Pl.’s Supplemental Br. Concurring in the Use of Def.’s Calculation of Interest), the district court adopted the defendant's calculation. J.A. at 66 (Am. Supplemental Post-Judgment Order 12/4/94). The defendant’s calculations are purportedly "based upon 9% annual simple interest, compounded annually,” J.A. at 258 (Def.’s Calculation of Interest). Because plaintiffs' challenge to the prejudgment interest award, both below and on appeal, focused on the rate of prejudgment interest utilized by the district court, we conclude the plaintiffs waived any *620 objections they may have raised to the formula used by the defendant and the district court in calculating the prejudgment interest award.
. 29 U.S.C. § 1132(g)(1) provides that "[i]n any action under [29 U.S.C. § 1132] ... by a participant, beneficiary, or fiduciary, the court in its discretion may allow a reasonable attorney's fee and costs of action to either party.”
. The plaintiffs do not contend that the district court abused its discretion with respect to its determination of a reasonable hourly fee or its calculation of the reasonable amount of hours necessary to perform the legal services rendered by the plaintiffs' attorneys.
. The plaintiffs argue that because the parties entered into a contractual employment relationship that at the time was governed by state law, they reasonably expected that Michigan law would govern their rights and obligations.
See
PIs.-appellants' Br. at 15. In focusing on the parties' contractual employment relationship, the plaintiffs frame the issue too broadly. Although ERISA generally governs employees’ and employers' rights and obligations with respect to retirement benefit plans, this does not mean that every issue that arises under ERISA automatically concerns the parties' employment relationship.
