Plaintiffs, the trustees of four union trust funds and the Colorado Tile, Marble and Terrazzo Contractors Association, brought this action against defendant St. Paul Mercury Insurance Company seeking to recover under a surety bond St. Paul had issued to Wilkinson & Company. Plaintiffs’ claims are based on a judgment in their favor in a separate action they brought against Wilkinson (the Wilkinson action or case) seeking fringe benefit contributions and other damages under collective bargaining agreements applicable to Wilkinson’s work at the Denver International Airport. The district court held that the surety bond St. Paul issued covered these damages and entered judgment in plaintiffs’ favor. St. Paul appeals. 1
In the meantime, Wilkinson appealed the judgment against it. We recently affirmed the district court’s judgment against Wilkinson as it applied to the plaintiff trustees, but vacated the judgment and remanded the case as it applied to .the Contractors Association.
See Trustees of Colo. Tile, Marble & Terrazzo Workers Pension Fund v. Wilkinson & Co.,
Nos. 96-1205, 96-1431,
On the merits, we reject St. Paul’s argument that the district court lacked subject matter jurisdiction, but agree that the type of damages plaintiffs seek are not covered under the surety bond. We therefore reverse.
I. BACKGROUND
This case follows directly from plaintiffs’ success on the claims they asserted in the Wilkinson action, which ¡they filed in February 1994. That case essentially turned on whether Wilkinson, a New Jersey corporation, was required to use union labor on work it performed under subcontract at the Denver International Airport in Colorado. With one exception to be discussed later, plaintiffs are the same in both this ease and the Wilkinson action. Plaintiff trustees are the named fiduciaries of four multiemployer welfare and pension benefit plans as defined by the Employee Retirement Income Security *1368 Act of 1974 (“ERISA”). They based their claims against Wilkinson on Section 515 of ERISA, 29 U.S.C. § 1145. Section 515 allows federal actions against employers for contributions allegedly due under the terms of multiemployer ERISA plans or collective bargaining agreements. Plaintiff Contractors Association is a Colorado nonprofit corporation that promotes the tile, marble and terrazzo trade in Colorado who also claimed it was due contributions under collective bargaining agreements.
The facts, briefly stated, were that Wilkinson was a signatory to a collective bargaining agreement between the Tile Contractors Association of Northern New Jersey, Inc., and Local No. 77 of New Jersey-Bricklayers and Allied Craftsmen (the “Local 77 CBA”). That agreement generally covered workers known as “helpers” or “finishers.” That agreement also contained a “traveling contractors” clause requiring Wilkinson to comply with an affiliated local’s collective bargaining agreement when Wilkinson performed work outside the territory covered by the Local 77 CBA and in an affiliated local’s territory.
Plaintiffs claimed that the work Wilkinson performed on the airport project was the type of work covered by the Local 77 CBA, and that pursuant to the Local 77 CBA traveling contractors clause, Wilkinson was obligated to comply with the union affiliate’s agreement covering the airport project site. The applicable local agreement was one involving Local Union No. 6 of Colorado, International Union of Bricklayers and Allied Craftsmen (the “Colorado CBA”). That agreement essentially required the use of union labor and also required employers to make contributions to plaintiffs based on the number of hours worked by covered workers. Wilkinson neither used union labor nor made the contributions. Plaintiffs contended that Wilkinson breached the Colorado CBA and sought, as damages, contributions, interest and liquidated damages under the Colorado CBA and various trust fund agreements incorporated into that agreement for all workers the agreement covered.
The district court agreed with plaintiffs that under the plain language of the Local 77 CBA, the airport project was the type of work covered by the agreement. The court also determined that the Colorado CBA controlled the amount of damages, and Wilkinson was therefore obligated to make contributions for all workers covered by that agreement. It therefore entered judgment in plaintiffs’ favor in the amount of $197,-098.76 plus attorney fees and costs.
In August 1994, prior to the district court’s ruling in their favor in the Wilkinson case, plaintiffs brought this action alleging diversity jurisdiction under 28 U.S.C. § 1332 and seeking to recover the amounts they claimed Wilkinson owed them under the labor and material bond St. Paul issued to Wilkinson, pursuant to Colo.Rev.Stat. § 38-26-105(1); for the airport work. St. Paul moved to dismiss the complaint under Fed.R.Civ.P. 12(b)(6), but the district court denied the motion in October 1995 and on reconsideration, in March 1996. St. Paul filed its answer in April 1996. In September 1996, while plaintiffs’ summary judgment motion was pending, St. Paul again moved to dismiss, this time on grounds of lack of complete diversity. St. Paul, a citizen of Minnesota for diversity purposes, raised two arguments for lack of diversity: (1) that the citizenship of an ERISA plan is based on the citizenship of plan participants, not the plan’s trustees, and plaintiffs could not show they were diverse from St. Paul; and (2) even if the plans’ citizenship were based on the citizenship of its trustees, there was not complete diversity because one of the trustees was a citizen of Minnesota. Plaintiffs responded by contending that the citizenship of the plans derived from the citizenship of the trustees and by moving to amend the complaint to delete the nondiverse trustee to maintain diversity.
Relying on
Navarro Savings Association v. Lee,
On appeal, St. Paul raises three arguments: (1) the district court lacked subject matter jurisdiction because the parties were not completely diverse; (2) the type of claim plaintiffs asserted was not covered by the bond; and (3) ERISA preempts plaintiffs’ claims.
II. DISCUSSION
A. Jurisdiction
St. Paul challenges both the basis on which the district court determined plaintiffs’ citizenship for diversity purposes and the court’s decision that the nondiverse trustee was not an indispensable party under Fed.R.Civ.P. 19 and could be dismissed to preserve diversity under Rule 21. The first issue goes to subject matter jurisdiction, and we review the district court’s determination de novo.
See FDIC v. Hulsey,
St. Paul contends that ERISA plans are unincorporated associations rather than trusts. Because the citizenship of unincorporated associations is based on the citizenship of all association members,
see, e.g., Tuck v. United Servs. Auto. Ass’n,
In
Navarro,
the ease on which the district court relied, the Court addressed an argument somewhat similar to St. Paul’s — that a trust, in that case, a business trust, was actually an unincorporated association and that its citizenship should be based on the citizenship of its shareholders rather than its trustees.
See
[e]arly in its history, this Court established that the “citizens” upon whose diversity a plaintiff grounds jurisdiction must be real and substantial parties to the controversy. Thus, a federal court must disregard nominal or formal parties and rest jurisdiction only upon the citizenship of real parties to the controversy.
id.
at 460-61,
a trustee is a real party to the controversy for purposes of diversity jurisdiction when he possesses certain customary powers to hold, manage, and dispose of assets for the benefit of others. The trustees in this case have such powers. At all relevant times, [the trust] operated under a declaration of trust that authorized the trustees to take legal title, to trust assets, to invest those assets for the benefit of the shareholders, and to sue and be sued in their capacity as trustees. [The trustees] filed this lawsuit in that capacity____ [The trust’s beneficial shareholders] can neither control the disposition of this action nor intervene in the affairs of the trust except in the most extraordinary situations.
*1370 We conclude that these respondents are active trustees whose control over the assets held in their names is real and substantial. That the trust may depart from conventional forms in other respects has no bearing on this determination____ [The trustees] have legal title; they manage the assets; they control the litigation. In short, they are the real parties to the controversy.
Id.
at 464-65,
We agree with the district court that
Navarro
controls this case, and we find St. Paul’s efforts to distinguish
Navarro
unpersuasive.

As in
Navarro,
the trustees brought suit in their own name in their capacities as trustees of an express trust. St. Paul contends that ERISA plans are not trusts because “[t]rusts are entities typically created under state law[, but] ERISA plans are governed by a complex set of federal statutes.” Appellant’s Br. at 8. Regardless of what law applies, we cannot see how it can seriously be argued that an employee benefit plan under ERISA is not an express trust.
Compare, e.g.,
Restatement (Second) Trusts § 2 (defining express trust generally as a “fiduciary relationship with respect to property”),
with
29 U.S.C. §§ 1101-1114 (describing fiduciary responsibilities with respect to ERISA plans including, inter alia, requirements that named fiduciaries have authority to manage and control plans (§ 1102(a)(1)) and that with limited exception all plan assets be held in trust (§ 1103(a))). Moreover, there is no question — indeed, St. Paul does not even attempt to argue to the contrary— that the trustees here possess the “customary powers to hold, manage, and dispose of assets for the benefit of others,”
Navarro,
St. Paul cites three post
-Navarro
eases in which courts have considered ERISA plans as unincorporated associations for diversity purposes.
See Laborers Local 938 Joint Health & Welfare Trust Fund v. B.R. Starnes Co.,
*1371
St. Paul also contends that this case is controlled not by
Navarro
but by
Carden v. Arkoma Assocs.,
We thus conclude that the district court correctly looked to the citizenship of the trustees for diversity purposes here. All of the trustees here are diverse from St. Paul save one — John Wallner, a trustee of the Bricklayers and Allied Craftsmen International Health Fund and the Bricklayers and Trowel Trades- International Pension Fund. The question now is whether the district court was correct in dismissing Wallner under Rule 21 to preserve diversity.
“[I]t is well-settled that Rule 21 invests district courts with authority to allow a dispensable nondiverse party to be dropped at any time [to preserve diversity jurisdiction], even after judgment has been rendered.” Newm
an-Green, Inc. v. Alfonzo-Larrain,
St. Paul contends that if the citizenship of the ERISA plans is determined by the citizenship of the trustees, then all of the trustees must be considered at all times, relying on the Court’s statement in
Carden
that “[w]e have never held that an artificial entity, suing or being sued in its own name, can invoke the diversity jurisdiction of the feder
*1372
al courts based on the citizenship of some but not all of its members,”
Again, we find
Carden
inapposite because this case does not involve an artificial entity “suing or being sued in its own name.”
6
We also reject St. Paul’s argument that all trustees must be indispensable under Rule 19(b) and that a trustee is therefore not susceptible to dismissal under Rule 21. St. Paul cites no authority supporting what would amount to a categorical, technical rule that all trustees are always indispensable parties; the only case addressing a similar situation of which we are aware is to the contrary.
See Prescription Plan Serv. Corp. v. Franco,
St. Paul’s concern with abusive forum shopping can be addressed through the analysis of indispensability.
See id.
at 111,
As the party seeking dismissal for inability to join an allegedly indispensable party, St. Paul has the burden of persuasion.
See Rishell,
first, to what extent a judgment rendered in the person’s absence might be prejudicial to the person or those already parties; second, the extent to which, by protective provisions in the judgment, by the shaping of relief, or other measures, the prejudice can be lessened or avoided; third, whether *1373 a judgment rendered in the person’s absence will be adequate; fourth, whether the plaintiff will have an adequate remedy if the action is dismissed for nonjoinder.
Rule 19(b). St. Paul addresses only the first of these factors, contending that it could be prejudiced by Wallner filing a separate state court action should the trustees fail to prevail in this action. This contention, however, fails to consider the res judicata effect of a judgment against the other trustees, since all trustees would be suing in their representative capacities and almost certainly be found to be in privity with each other. Moreover, under the second factor, the court could avoid any possible prejudice by fashioning relief to require the party trustees to bind the trust, and consequently the other trustee, to the judgment rendered in this case. The third factor, which includes public .and judicial interests in complete and efficient resolution of disputes,
see Provident Tradesmens Bank,
We therefore conclude that the district court did not abuse its discretion in dismissing Wallner as dispensable to preserve diversity and hold that the court ’ had subject matter jurisdiction.
B. Colorado Public Works Act
St. Paul issued the bond to Wilkinson pursuant to the Colorado Public Works Act, Colo.Rev.Stat. §§ 38-26-101 to 107. That act requires that a contractor on a public works construction project shall execute a penal bond with good and sufficient surety
conditioned that such contractor shall at all times promptly make payments of all amounts lawfully due to all persons supplying or furnishing him or his subcontractors with labor, materials, rental machinery, tools, or equipment used or performed in the prosecution of the work provided for in such contract____ Subcontractors, mate-rialmen, mechanics, suppliers of rental equipment, and others may have a right of action for amounts lawfully due them from the contractor or subcontractor directly against the principal and surety of such bond.
Colo.Rev.Stat. § 38-26-105(1). 7 St. Paul contends that this statute does not cover the fringe benefit contributions for which plaintiffs seek recovery here because those contributions do not directly relate to any labor actually supplied or furnished to Wilkinson, but instead are simply damages for breach of the Colorado CBA.
In concluding that the contributions were covered by the statute, the district court relied on
Trustees of Colo. Carpenters & Millwrights Health Benefit Trust Fund v. Pinkard Constr. Co.,
We review the district court’s interpretation of state law de novo,
Salve Regina College v. Russell,
Colorado courts have not yet addressed whether § 38-26-105 covers breach of contract damages, but the general rule is that such damages, including lost profits,
8
are not recoverable under public works bond statutes.
See, e.g., Lucas v. Western Cas. & Sur. Co.,
III. CONCLUSION
We conclude that the district court erred in- holding that the damages plaintiffs seek are covered under § 38-26-105 and recoverable under the bond St. Paul issued to Wilkinson. We therefore do not need to address St. Paul’s ERISA preemption argument. The judgment of the district court is REVERSED.
Notes
. After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed. R.App. P. 34(a); 10th Cir. R. 34.1.9. The case is therefore ordered submitted without oral argument.
. St. Paul does not challenge the trustees’ capacity to bring this action.
See
Rule 17(a) (trustee of express trust "may sue in that person’s own name without joining the party for whose benefit the action is brought”);
see also Navarro,
. New decisions address the citizenship of ERISA plans for diversity purposes. Most cases seem to note their status as express trusts and move on.
See, e.g., Central States, S.E. &
S.W.
Areas Pension Fund v. Art Pape Transfer, Inc.
. In
Carden,
the Court seemed to acknowledge that the analyses in
Navarro
and
Carden
appear at odds: "The resolutions we have reached above can validly be characterized as technical, precedent-bound, and unresponsive to policy considerations raised by the changing realities of business organization. But, as must be evident from our earlier discussion, that has been the character of our jurisprudence in this field____”
. Unfortunately, the district court did not fully explain in its brief oral order on this matter why it concluded Trustee Wallner was not indispensable under Rule 19(b), why in "equity and good conscience” the case could proceed without him, or why it was "just” to dismiss Trustee Wallner under Rule 21. This court is always concerned that reviewing a district court’s exercise of discretion on a complex matter with an inadequate record runs the risk of having this court exercise that discretion in the first instance, something we are not empowered to do. In this instance, however, we conclude that the record is marginally sufficient to allow this court to review the district court's exercise of discretion in these matters.
. We express no opinion on this issue as it might apply to cases in which the party is the ERISA plan or trust fund itself.
. The parties' arguments assume that the scope of the bond is governed by this statute. We proceed from that assumption.
. In a broad sense, the unpaid contributions here are similar to lost profits. They are amounts the ERISA plans would have "earned” had Wilkinson complied with the Colorado CBA.
. The Colorado Supreme Court has relied on both the Miller Act and other states’ public works bond acts in interpreting analogous provisions in the Colorado act.
