OPINION
¶ 1 The Arizona State Retirement System, the Arizona Board of Regents, and the State of Arizona (collectively, “ASRS”) previously appealed from a post-settlement award of attorney fees to counsel representing state employee James Burke and a class of similarly situated state employees. ASRS argued the fee award was unreasonably high because the trial court erroneously applied the “common fund doctrine” rather than the hourly “lodestar” method of calculating fees. In an opinion filed April 29, 2003, we agreed with ASRS because we found the common fund doctrine inapplicable to the parties’ settlement agreement and further determined that application of the common fund doctrine is precluded when a fee award is authorized under A.R.S. § 12-341.01.
Burke v. Ariz. State Ret. Sys.,
¶2 Class counsel moved for reconsideration, arguing,
inter alia,
that our analysis was flawed because the operative contract was solely the parties’ settlement agreement rather than the class’s underlying employment contracts. After considering class counsel’s motion and the response filed by ASRS, we find class counsel’s point well taken and conclude it obviates our statutory discussion in the opinion. However, because we conclude, as before, that the common fund method of awarding attorney fees remains fundamentally inapplicable on the facts of this case, the outcome remains the same. Accordingly, we grant the motion to the ex

Facts and Procedural Background
¶ 3 Burke filed a complaint against ASRS on behalf of himself and similarly situated state employees in 1996, seeking judicial review of ASRS’s administrative decision that their retirement compensation rights were not adversely affected when ASRS transferred the employees from a defined contribution plan to a defined benefit plan. The complaint alleged causes of action for breach of contract, impairment of contract, promissory estoppel, breach of fiduciary duty, violation of 42 U.S.C. § 1983, and related theories. In addition to monetary damages, Burke requested “reasonable attorneys’ fees” without specifying a basis for that request. The trial court certified the class as those state employees whom ASRS had transferred from the defined contribution program to the defined benefit program. See Ariz. R. Civ. P. 23, 16 A.R.S., Pt. 1. Shortly thereafter, the court ruled in Burke’s favor on his administrative review claim and entered a judgment ordering ASRS to recalculate his retirement benefits and containing language pursuant to Rule 54(b), Ariz. R. Civ. P., 16 A.R.S., Pt. 2. The court awarded Burke his attorney fees and costs, presumably under AR.S. § 12-341.01, which authorizes a discretionary fee award to the prevailing party in an action arising out of a contract. 1 ASRS appealed.
¶4 Meanwhile, the class had moved for partial summary judgment on the' ground the court’s ruling on Burke’s administrative claim constituted the law of the case on the class’s impairment-of-contract cause of action, arguing the same analysis also applied to the class. ASRS opposed the motion and filed a cross-motion for summary judgment, arguing that most of the class members had waived their claims by accepting modified pension benefits or had failed to exhaust their administrative remedies and that the claims of unretired class members were not ripe. While the motions were pending, the parties agreed to several stays while conducting settlement negotiations. 2 Eventually, the parties entered into a settlement agreement that provided ASRS would pay each class member the greater amount of benefits to which he or she would be entitled under either the defined contribution program or the defined benefit program. ASRS also agreed to pay “reasonable attorneys’ fees for representation of the Class” but reserved the right to challenge class counsel’s fee application. 3

arguing that fees paid by a settling defendant are properly included as part of the common fund of increased retirement benefits for the class members created by the settlement and are properly calculated as a percentage of that fund. ASRS objected on the grounds that this was not a common fund, fee-sharing ease but a fee-shifting case and that fees should be calculated using an hourly lodestar method. The trial court found that fees were “payable pursuant to the negotiated agreement of the parties embodied in the Stipulation of Settlement, which require[d] a discretionary decision by th[e] Court” and that there was no statutory
Standard of Review
¶ 6 In granting class counsel’s fee application, the trial court concluded that fees were not awardable under any fee-shifting statutes and that the common fund doctrine was the appropriate basis for awarding fees in this case. ASRS argues that the court erred in both respects. Whether a fee statute applies is a question of law.

¶ 10 Moreover, “[u]nder regular common fund procedure, the parties settle for the total amount of the common fund and shift the fund to the court’s supervision. The plaintiffs’ lawyers then apply to the court for a fee award from the fund.”
Staton v. Boeing Co.,
¶ 11 In its decision to apply the common fund doctrine, the trial court relied on two cases class counsel cited,
Johnston v. Comerica Mortgage Corp.,
¶ 12 First, they are distinguishable from the present situation.
Johnston
involved two settlement agreements described by the court as “package deal[s],” which provided lump sum recoveries for each plaintiff class involved, injunctive relief, and “clear sailing” provisions whereby the defendant agreed not to oppose fee requests that did not exceed specified máximums.
¶ 13 Similarly, in
General Motors,
the defendant was not challenging the methodology for determining the fee award. In fact, General Motors agreed to the fees requested by class counsel and approved by the trial court, and defended the award on appeal. In agreeing with objecting class members that the common fund doctrine was preferable to the lodestar method under the facts of the case, although not necessarily required, the Third Circuit noted: “In this case, the fee clearly was not made pursuant to a statute; therefore no legislatively endorsed policy favors assuring counsel an adequate fee.”
¶ 14 More importantly, we disagree with the reasoning in Johnston and General Motors to the extent these cases support class counsel’s argument that “a defendant’s agreement to pay attorneys’ fees is part of the class benefit recovered”; thus, “the fees here do come from the fund and are borne by those who benefit, ie., the Class Members.” We reject that theory as superficially plausible but effectively rewriting the common fund doctrine. That doctrine is founded on
the historic power of equity to permit the trustee of a fund or property, or a party preserving or recovering a fund for the benefit of others in addition to himself, to recover his costs, including his attorneys’ fees, from the fund or property itself or directly from the other parties enjoying the benefit.

¶ 15 We find equally unpersuasive class counsel’s argument that the trial court could, in its discretion, nonetheless find that the parties intended that the common fund doctrine apply. After a hearing on ASRS’s motion for reconsideration, the trial court expressly found that ASRS had previously acknowledged that fees may be authorized under the common fund doctrine and chided the agency for taking a contrary position. But the record does not support that finding or the court’s related comments. The court appears to have based its determination solely on a letter from ASRS counsel, written during settlement negotiations, that included a statement that fees “may be authorized under A.R.S. § 12-341.01 or 12-348 or the common fund doctrine or the substantial benefit doctrine.” Read in context, however, it is clear that counsel’s statement was not a concession that fees either would be or should be awarded under the common fund doctrine but was merely a listing of all possibilities. Indeed, counsel so testified at the hearing. Furthermore, the court’s additional determination that ASRS, “in agreeing to pay an unspecified ... award of attorneys’
¶ 16 Finally, as noted earlier, the common fund doctrine is based on the equitable principle that those who receive the benefits of a plaintiffs litigation should not be unjustly enriched and should thus share in compensating plaintiffs counsel for the benefits produced.
Steer, Kerr.
That objective is not served under the trial court’s approach here. The record reveals no issue of unjust enrichment of the class having ever been raised or discussed, and no amount was included in the class recovery fund to provide or offset a percentage-of-the-fund fee award for class counsel.
See, e.g., Staton,
Conclusion
¶ 17 Although some hallmarks of the common fund doctrine are present here, the primary element — the spreading of attorney fees among the benefited class — is glaringly absent. Notwithstanding class counsel’s semantic argument, the settlement agreement and record here establish a fee-shifting, rather than a fee-sharing, scenario. In such a setting, lodestar analysis is the proper method for determining the fee award. See Camden I Condo. Ass’n; Kerr. Although Kerr, upon which class counsel relies, uses the term “fee shifting” in discussing both types of scenarios, that case only supports our analysis because the court there correctly applied the common fund doctrine to award attorney fees as an offset from the class members individual recoveries, not as a separate and additional amount to be paid by the state, as in this case. Thus, contrary to class counsel’s assertion, the trial court did not “match the facts to the [common fund] paradigm,” and it erred in applying that doctrine to determine an appropriate award of attorney fees here.
¶ 18 ASRS further argues that, because the class litigation arose from the class’s employment contracts, fees were properly awardable pursuant to § 12-341.01(A), an assertion class counsel refutes. But we need not address that issue or class counsel’s additional arguments in light of our conclusions above. We therefore vacate the trial court’s attorney fee award and remand the matter for it to determine a reasonable award by applying appropriate fee-shifting guidelines as set forth in
Schweiger v. China Doll Restaurant, Inc.,
¶ 19 In making its determination, the trial court should ascertain a reasonable billing rate for class counsel’s time and the hours reasonably expended on the case. See id.; see also ABC Supply. “[E]vidence of reasonableness is required even in contingency fee cases, [and] “ ‘[t]he most useful starting point for determining the amount of a reasonable fee is the number of hours reasonably expended on the litigation multiplied by a reasonable hourly rate.’ ” ”
