Elaine and Robert Whiting owned Pioneer Ranch Limited Partnership, a vacation property on which they farmed and raised cattle. The Whitings also owned a trucking company, which, after several years of operation, became bankrupt and ceased doing business. The Central States, Southeast and Southwest Areas Pension Fund (“the Fund”), a multi-em-ployer pension fund, assessed substantial withdrawal liability on the trucking company, but could not collect any of the amount owed. The Fund sued Pioneer Ranch and Robert Whiting for the withdrawal liability. The district court granted the Fund’s motion for summary judgment, concluding that Pioneer Ranch was responsible for the trucking company’s liability under the *574Multiemployer Pension Plan Amendments Act of 1980 (“MPPAA”), 29 U.S.C. §§ 1381-1461 (1980). Pioneer Ranch appeals. For the following reasons, we affirm.
I. Background
A. Statutory Background
Congress passed the MPPAA as an amendment to the Employee Retirement Income Security Act (“ERISA”), 29 U.S.C. §§ 1001-1371. Under ERISA, the Pension Benefit Guaranty Corporation (“PBGC”), a government corporation, protects covered employees by insuring their benefits against fund insolvency or premature termination. Prior to 1980, ERISA’s contingent liability provisions gave employers an incentive to withdraw from financially weak multi-employer plans to avoid liability if the plan terminated in the future. As a result, the PBGC reported to Congress that the premiums paid to it were insufficient to cover its expected future liabilities. Congress then passed the MPPAA, seeking to discourage voluntary withdrawals from multi-employer plans by imposing a mandatory liability on all withdrawing employers. See Cent. States, Se. and Sw. Areas Pension Fund v. Ditello, 974 F.2d 887, 888 (7th Cir.1992). The Act holds such employers liable for their proportionate share of “unfunded vested benefits.” 29 U.S.C. § 1381.
Upon an employer’s withdrawal from a plan, the trustees of the fund must promptly determine the amount of an employer’s liability and create a payment schedule. Within 90 days of notification, the employer may request that the trustees review their determination. 29 U.S.C. § 1399(b)(2)(A). If either party is dissatisfied with the outcome of the review, the MPPAA mandates arbitration proceedings. 29 U.S.C. § 1401(a)(1) (“Any dispute between an employer and the plan sponsor ... shall be resolved through arbitration.”). After arbitration, or if no arbitration proceeding has been initiated, either party may bring an action in federal district court “to enforce, vacate, or modify the arbitrator’s award.” 29 U.S.C. § 1401(b)(2).
Section 1301(b)(1) provides that all “employees of trades or businesses (whether or not incorporated) which are under common control shall be treated as employed by a single employer and all such trades and businesses as a single employer.” 29 U.S.C. § 1301(b)(1). Under this section, each trade or business under common control is jointly and severally liable for the withdrawal liability of the others. See Ditello, 974 F.2d at 889.
B. Facts
In 1970, Robert and Elaine Whiting1 purchased property located in Cheboygan County, Michigan to use as a vacation home. The Whitings kept a number of cattle and other livestock on the property and conducted some farming and ranching activities. In 1973, the Whitings hired David McCormick to care for the property and assist with the farming and livestock. Over the next twenty years, the Whitings used the property as a vacation home and developed a small cattle herd by buying and selling a few cattle each year.
In 1993, the Whitings established the Pioneer Ranch Limited Partnership. Elaine and Robert were both general and limited partners, and their four children, R. Scott Whiting, Daniel Whiting, Jo Ann Skandalaris, and Jane Whiting were limited partners. Pioneer Ranch’s partnership agreement stated that the partnership’s purpose was as follows:
*575(a) acquiring and holding certain real property located in the Township of Aloha, Cheboygan County, Michigan, heretofore owned and managed as a cattle farm by the General Partners.
(b) acquiring additional real and personal property to be used in operating, managing, and expanding the Property, and to engage in the business of fanning, ranching, and any agricultural pursuit or undertaking; and
(c) doing any and all things and carrying on any and all other activities necessary, convenient, or incidental to accomplish any of the preceding purposes and powers or to protect and benefit the Partnership.
After the Whitings established the partnership, they handled the livestock on the ranch the same way they handled it before 1993.
From 1994 through 2003, Pioneer Ranch filed tax returns that contained a schedule listing profits and losses from farming. The schedule indicated that Pioneer Ranch lost money every year after the Whitings established the partnership. On its tax returns, the partnership fisted “cattle farm” as its principal business activity, claimed farm expenses, and certified that it was entitled to an agricultural production exemption.
The Whitings also owned a trucking company called Whiting Distribution Services (“WDS”), which operated in Detroit, Michigan. In 2003, WDS, which had been experiencing financial difficulties, entered bankruptcy and wound up its operations. WDS was subject to a series of collective bargaining agreements requiring pension contributions to the Fund. On December 6, 2003, WDS withdrew from the Fund. On January 30, 2004, the Fund demanded that the Wfiiiting Controlled Group pay $3,708,184.81 worth of withdrawal liability pursuant to ERISA, 29 U.S.C. §§ 1382(2) and 1399(b). On August 23, 2005, the Fund issued another notice and demand to the Whiting Controlled Group that was served on Pioneer Ranch and Robert Whiting. On February 15, 2006, the Whiting Controlled Group, through Pioneer Ranch, received a notice that the withdrawal liability payments were past due. Wfiien the Whiting Controlled Group failed to pay the withdrawal liability, the Fund filed suit in federal district court, arguing that it could collect the withdrawal liability from Pioneer Ranch and Robert Whiting because Pioneer Ranch was a “trade or business” under § 1301(b)(1).
On June 15, 2006, the parties filed cross-motions for summary judgment. On July 20, 2006, the district court granted the plaintiffs’ motion for summary judgment and denied the defendants’ motion, holding that Pioneer Ranch was a trade or business under § 1301(b)(1).
II. Discussion
A. Standard of Review
The initial question presented in this case is the standard by which we review the district court’s decision. We ordinarily review a district court’s grant of summary judgment in an ERISA case de novo. Santaella v. Metro. Life Ins. Co., 123 F.3d 456, 460 (7th Cir.1997). However, in Central States, Southeast and Southwest Areas Pension Fund v. Slotky, 956 F.2d 1369, 1373-74 (7th Cir.1992), this Court held that the clearly erroneous standard of review applies when the only issue before the district court is the characterization of undisputed subsidiary facts and where a party does not have the right to a jury trial. In Slotky, the Court stated that although the fact of whether or not an enterprise is a trade or business is not ordinarily resolved on summary judgment, “[delaying judgment] does not make sense in a case in which the only factual issue is *576one of characterization, ... and the opponent of summary judgment claims no right to a jury trial.” Id. at 1374. In that scenario, “both the record and the fact-finder are the same in the summary judgment proceeding as they would be in a trial. There is no more evidence to put in and no different trier to evaluate it.” Id. As we explain below, there is no dispute over the underlying facts in this ease. Thus, to determine the appropriate standard of review, we must analyze whether the defendants are entitled to a jury trial.2
The Seventh Amendment provides that “[in] Suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved.” U.S. Const, amend. VII. The Supreme Court has long understood “ ‘suits at common law’ to refer not merely to suits that the common law recognized among its old and settled proceedings, but to suits in which legal rights were to be ascertained and determined, in contrast to those where equitable rights and remedies were recognized.” Feltner v. Columbia Pictures Television, Inc., 523 U.S. 340, 348, 118 S.Ct. 1279, 140 L.Ed.2d 438 (1998) (quoting Parsons v. Bedford, 28 U.S. 433, 447, 3 Pet. 433, 7 L.Ed. 732 (1830)). The general rule in ERISA cases is that there is no right to a jury trial because “ERISA’s antecedents are equitable,” not legal. Mathews v. Sears Pension Plan, 144 F.3d 461, 468 (7th Cir.1998). However, § 4301(a)(1) permits plan fiduciaries, employers, participants, or beneficiaries to bring civil suits under Title IV of ERISA and seek appropriate legal or equitable relief with respect to a multi-employer plan. 29 U.S.C. § 1451(a)(1). Though § 4301(a)(1) provides for both legal and equitable remedies in the case of multi-employer pension plan disputes, the few courts that have considered the question have determined that the Seventh Amendment does not guarantee a jury in these types of cases. See Connors v. Ryan’s Coal Co., 923 F.2d 1461 (11th Cir.1991); Bd. of Trs. of W. Conference of Teamsters Pension Trust Fund v. Thompson Bldg. Materials, Inc., 749 F.2d 1396 (9th Cir.1984).
In Thompson Building Materials, Inc., the Ninth Circuit held that. Congress did not violate the Seventh Amendment by requiring employers and plan sponsors to resolve disputes about withdrawal liability through arbitration. 749 F.2d at 1405. The court held that the MPPAA’s statutory scheme was not known to the common law, and that Congress may delegate fact-finding functions to non-jury bodies in cases involving newly created statutory rights. Id. Likewise, in Connors, the Eleventh Circuit held that the defendant was not entitled to a jury in a withdrawal liability collection action brought by multi-employer plan trustees. 923 F.2d at 1465. The court stated that the MPPAA’s mandatory arbitration provisions did not unconstitutionally deprive the liable employer of its right to a jury trial. Id.
We agree with the reasoning of our sister circuits. If Pioneer Ranch had proceeded to arbitration to challenge its status as an employer it would not have been entitled to a jury. It is anomalous then to allow the defendants to have a jury trial simply because they avoided the dispute resolution scheme that Congress contemplated in the statute. Because the defen*577dants are not entitled to a jury trial, the Court must review the district court’s grant of summary judgment for clear error.
B. Trade or Business
To impose withdrawal liability on an organization other than the one obligated to the Fund, two conditions must be satisfied: 1) the organization must be under “common control” with the obligated organization, and 2) the organization must be a trade or business. Cent. States, Se. and Sw. Areas Pension Fund v. Fulkerson, 238 F.3d 891, 895 (7th Cir.2001). The defendants do not dispute that the Whitings controlled both WDS and Pioneer Ranch. The only question, therefore, is whether Pioneer Ranch constitutes a trade or business.
Although the MPPAA does not define “trade or business,” this Court has adopted the test established in Commissioner v. Groetzinger, 480 U.S. 23, 35, 107 S.Ct. 980, 94 L.Ed.2d 25 (1987), to determine whether an enterprise constitutes a trade or business. See Cent. States, Se. and Sw. Areas Pension Fund v. White, 258 F.3d 636, 642 (7th Cir.2001); Fulkerson, 288 F.3d at 895. Under Groetzinger, the Court must consider whether the person engaged in an activity 1) for the primary purpose of income or profit and 2) with continuity and regularity. 480 U.S. at 35, 107 S.Ct. 980. The phrase “trade or business” “does not encompass purely personal activities no matter how continuous or extended the activity may be nor how profitable....” White, 258 F.3d at 642 (internal quotation omitted). Additionally, “a sporadic activity, a hobby, or an amusement diversion does not qualify.” Groetzinger, 480 U.S. at 35, 107 S.Ct. 980.
The parties focus their dispute on whether the Whitings engaged in ranching and farming primarily for the purpose of income or profit. The defendants contend that the Whitings operated Pioneer Ranch for purely personal reasons, as a vacation home and retreat, and created the partnership for estate planning purposes.3 Additionally, they point out that the Whitings owned the land that became Pioneer Ranch for twenty-two years prior to establishing the partnership and that the manner in which they handled the livestock and farming on the ranch did not change in any way from the manner in which it was handled before 1993. They also emphasize that the Whitings suffered significant losses for nine straight years after they established the partnership, and that the property’s tennis courts, shuffleboard court, and trout pond all demonstrate that the Whitings intended Pioneer Ranch to be a vacation home because those things have nothing to do with ranching or farming. Finally, they allege that the Whitings acquired land that was largely unsuitable for either ranching or farming because Pioneer Ranch was an investment, not a trade or business.
By contrast, the Fund emphasizes the partnership agreement, which stated that the business purpose of Pioneer Ranch was “to engage in the business of farming, ranching, and any agricultural pursuit or undertaking....” Courts have held that “a defendant’s stated intention of forming a business is highly relevant, because it con*578stitutes a declaration against interest.” See, e.g., Connors, 995 F.2d at 254. The Fund also points out that the Whitings constructed fences to hold cattle, sold livestock and grains, employed one full-time employee and two part-time employees, and provided the employees with health, retirement, and workers’ compensation benefits. They also highlight the fact that the Whitings’ tax returns claimed business exemptions and deductions for farming expenses each year. Moreover, from 1994 through 2003, Pioneer Ranch represented that its principal business activity was cattle farming and that it generated an annual income of $20,000.
On these undisputed underlying facts, the district court held that Pioneer Ranch is a trade or business. Even if this Court might have interpreted the facts differently, a fact finder could reasonably consider the documentary evidence of the Whitings’ intent and conclude that they engaged in the activities on Pioneer Ranch for the primary purpose of income or profit and simply derived incidental personal benefit from Pioneer Ranch.
The defendants maintain that it would be fundamentally unfair to impose withdrawal liability on Pioneer Ranch.4 They argue that, as in Fulkerson and White, this Court should reverse summary judgment. Fulkerson and White are readily distinguishable from this case because they addressed legal errors about whether the activities in those eases were sufficiently regular and continuous, an issue that is undisputed in this case.
Because there are no disputed facts and the defendants are not entitled to a jury trial, if the Court remands the case for a trial, the same trier of fact will consider the same evidence on which it already concluded that no fact-finder could reasonably find that Pioneer Ranch was not a trade or business. Because the district court committed no errors of law, and a reasonable fact finder could conclude that Pioneer Ranch was a trade or business, the district court did not commit clear error.
III. Conclusion
For the above reasons, we AffiRM the district court’s grant of summary judgment to the plaintiffs.
. Elaine Whiting died on January 5, 2005, and Robert Whiting died on February 4, 2006.
. The appellants stated that they were entitled to a jury trial while the appellees contended that they were not entitled to one, but neither party explained why the appellants were or were not entitled to a jury trial. Indeed, both parties presented deficient arguments for their preferred standard of review. Accordingly, it falls to us to reach the merits of the jury trial issue in order to determine the appropriate standard of review.
. The four Whiting children each testified that their parents told them that they established Pioneer Ranch Limited Partnership on the advice of their accountants and lawyers. Though the children’s testimony is inadmissible hearsay, there is admissible evidence that the Whitings established Pioneer Ranch for estate planning purposes. Each year the Whitings gave their children un-taxable gifts of land, which is consistent with estate planning.
. We note that parties are responsible for whatever legal consequences attach to their own choice of business organization. See Connors, 995 F.2d at 254.
