Opinion for the Court filed by Chief Judge SENTELLE.
In this intеrlocutory appeal, both plaintiffs and defendants in protracted litigation over trust accounts held by federal officials on behalf of American Indians seek review of orders of the district court. The district court held the Department of the Interior to be in continuing breach of its duty to account for trust funds and that accounting for the funds was impossible; it ordered monetary relief to the members of the plaintiff class. On review, we hold that while the district court’s analysis of duty and breach are generally correct, the court erred in freeing the Department of the Interior from its burden to make an accounting. We therefore vacate the district court’s orders and remand for further proceedings.
I. Background
In 1996, beneficiaries of Individual Indian Money (IIM) trust accounts brought this class action against the Secretary of the Interior, the Secretаry of the Treasury, and the Assistant Secretary of the Interior for Indian Affairs, alleging that those officials had violated their fiduciary duties as trustees acting on behalf of the United States.
See Cobell v. Babbitt,
Plaintiffs and defendants cross appeal from two orders of the district court. The first,
Cobell v. Kempthorne,
Soon after issuing Cobell XXI, the district court certified an immediate interlocutory appeal from both decisions under 28 U.S.C. § 1292(b). Order (Sept. 4, 2008). All plaintiffs and all defendants petitioned for permission to appeal, and this court granted thе petitions. Orders (Nov. 21, 2008).
We now hold that the district court correctly held that the 1994 Act and
Cobell VI
required a full accounting, but erred in holding that an accounting cannot be conducted because, in the district court’s view, Congress will never appropriate the funds necessary to conduct such an accounting. The statute gives the plaintiff class a right to an accounting. Sitting in equity, the district court has the authority to approve a plan that efficiently uses limited government resources to achieve that goal. It is within the power of the district court to order an accounting without requiring Interior to perform analyses the costs of which exceed the benefits payable to individual American Indians. It would indeed be “nuts” to spend billions to recover millions.
Cobell XX,
As this case enters its thirteenth year, it becomes increasingly difficult to summarize its factual and procedural background.
See Cobell XX,
Since passage of the 1994 Act — and the filing of this lawsuit — the Department of the Interior has had mixed success in its efforts to account for the trust funds.
Co-bell XX,

In 2003, the district court issued a nine-
page
injunction.
See Cobell v. Norton,
After 2005 arrived without cоngressional action, the district court reissued the injunction that had been vacated by
Co-bell XIII.
Reasoning that “December 31, 2004 ha[d] come and gone” with “no legislative solution,” the district court held itself “bound, by its findings of fact and conclusions of law” in
Cobell X,
“to reissue without modification the ‘historical accounting’ provisions of its structural injunction.”
Cobell v. Norton,
When we vacated the district court’s injunction for abuse of discretion, we noted in particular that the injunction “caused the cost ... to rise by more than an order of magnitude, from $335 million over five years to more than $10 billion.” Id. at 1077. We then specifically approved the use of statistical sampling on the rationale that for some transactions, “the average cost of accounting, per transaction, would exceed the average value of the transactions.” Id. at 1078. We now take that reasoning a step further, and instruct the district court tо use its equitable power to enforce the best accounting that Interior can provide, with the resources it receives, or expects to receive, from Congress. Therefore we vacate the district court’s orders and remand for proceedings consistent with this opinion.
II. Analysis
Before beginning our analysis, we want to commend the district court for its ef *812 forts to cut through this Gordian knot in Cobell XX and Cobell XXI. While we vacate the district court’s orders, including its holding of imрossibility, we do so with substantial sympathy, recognizing that our precedents do not clearly point to any exit from this complicated legal morass.
A. The District Court’s Analysis
Bowing to our directive in
Cobell v. Kempthorne,
We recognize, as did the district court, that the courts face two mandates of deference in construing the relevant statutes at issue in this case. First, there is the familiar
Chevron
deference upon which the district court relied in reviewing Interior’s methodology. However, as the court observed,
Chevron
deference can be “ ‘trumped by the requirement that statutes are to be construed liberally in favor of the Indians, with ambiguous provisions interpreted to their benefit.’ ”
Id.
at 89 (quoting
Cobell XVIII,
In
Cobell VI,
we observed that “[ujnder traditional equitable principles, ‘[t]he trustee’s report must contain sufficient information for the beneficiary readily to ascertain whether the trust has been faithfully carried out.’ ”
Therefore, the district court was not completely correct when it said that “the proper
scope
of the accounting obligation .... is the result ... of a
legal
interpretation of the 1994 Act and other statutes governing the IIM trust.”
Cobell XX,
The plaintiffs are entitled to an accounting under the statute. 25 U.S.C. § 4011(a). The district court sitting in equity must do everything it can to ensure that Interior provides them an equitable accounting. The district court’s holding of impossibility contradicts the requirement of an equitable accounting — one that makes most efficient use of limited government resources. Given the realities of congressional appropriations, it would be inequitable for Interior to throw up its hands and stop the accounting. This is what the district court declared Interior should do in Cobell XX, leading to the money judgment of Cobell XXI. That judgment was substantial, but without an accounting, it is impossible to know who is owed what. The best any trust beneficiary could hope for would be a government check in an arbitrary amount. Even if this did justice for the class, it would be inaccurate and unfair to an unknown number of individual trust beneficiaries. There will be uncertainty in any accounting for this trust. Interior’s job is to minimize that unсertainty with a finite budget. Equity requires the courts to assure that Interior provides the best accounting it can.
B. An Equitable Accounting
The proper scope of the accounting ultimately remains a question for the district court, but we will provide as much guidance as we can on appropriate methodology, and principles to guide the analysis of unforeseen circumstances. The overarching aim of the district court should be fоr Interior to provide the trust beneficiaries the best accounting possible, in a reasonable time, with the money that Congress is willing to appropriate.
In
Cobell XVII,
we made clear that an equitable accounting may include the use of statistical sampling when verifying transactions.
See
The equitable approach we envision is illustrated by so-called
Youpee
escheatments. The Dawes Act, and subsequent legislation, allotted land to individual Indians that could not be sold or leased without permission of the government.
See Cobell XX,
The government may be correct, but for the wrong reason. To determine whether the accounting should cover the escheatments, the district court shоuld ask the practical question of whether the cost to account will exceed the amount recovered by class beneficiaries. As the district court observed, escheated “interests are tiny, generally of very low value, and the cost of reversing the escheatments is high.” Id. The district court should exercise its equitable power to ensure that Interior allocates its limited resources in rough proportiоn to the estimated dollar value of payments due to class members. It should also consider low-cost statistical methods of estimating benefits across class sub-groups.
Another illustration of the need for a flexible approach involves administrative fees. Interior often charged trust beneficiaries administrative fees “in connection with the probate process,” when the government sold timber on trust land, or when the government leased or sold trust land. Id. at 79. These fees were subtracted before money was deposited into beneficiary accounts, and, so the government argues, they should be excluded from any accounting. Again the government is probably right for the wrong reason. Common sense should guide the district court’s analysis in equity. Like escheatments, “[a]dministrative fees ... likely amount to a tiny fraction of the monies that pass through thе IIM trust.” Id. at 96. If accounting for them causes an enormous increase in cost — because, for instance, Interior has to integrate several new systems of records with the IIM trust — and only a small effect on the ultimate balances, then the district court is free to approve of Interior’s low-cost ways *815 to avoid this. The district court would be within bounds to accept a reasonable simplification of accounting for аdministrative fees, possibly extending to sampling and even exclusions. As in the case of escheatments, these modifications and exclusions should be made considering whether the cost to account exceeds a potential recovery for the class.
Just as equity affects the substance of the accounting, so it affects which accounts are subject to the accounting. First, we consider the legal case: The 1994 Act only requires accounting of “funds held in trust by the United States for the benefit of ... an individual Indian which are deposited or invested pursuant to the Act of June 24, 1938 (25 U.S.C. 162a).” 25 U.S.C. § 4011(a). The district court ordered accounting even for accounts closed before the 1994 Act was passed.
See Cobell XX,
This is another instance in which the limited resources of the historical accounting project may be better spent elsewhere. Accounting for closed accounts, dealing with probate and probate regulations, and considering the impact of the IIM trust on a host of heirs and creditors could needlessly further complicate an already complicated process. The purpose of an equitable accounting, as we have tried tо articulate, is for Interior to concentrate on picking the low-hanging fruit. We must not allow the theoretically perfect to render impossible the achievable good.
III. Conclusion
We vacate the orders of the district court and remand for further proceedings consistent with this opinion. 1
It is so ordered.
Notes
. We are hearing this case on interlocutory appeal. It does not appear that the issues raised by intervenor Osage Nation are yet ripe for review.
