Opinion for the Court filed by Chief Judge GINSBURG.
Riсhard Flores, individually and doing business as R.C. Construction, and Priscilla Flores, individually and doing business as R.C. Tile, appeal the judgment of the district court in favor of the Trustees of the Bricklayers and Trowel Trades International Pension Fund upon the Trustees’ claim under the Employment Retirement Income Security Act of 1974 (ERISA), 29 U.S.C. §§ 1001 et seq., for delinquent pension contributions. The appellants contend the district court overlooked genuinе issues of material fact and applied incorrect legal standards in concluding R.C. Tile was the alter ego of R.C. Construction and liable for its delinquent pension contributions. We affirm the judgment. *
I. Background
The three Flores brothers - Joseph, Richard, and Jesse - do tile work on public projects in southern California. Joseph Flores manages all operations of the family’s tile installation businesses; his wife, Priscilla Flores, oversees the finances and acts as office manager for the family’s businesses. Richard and Jesse Flores set tile and do not have management responsibilities.
Over the past thirty years the Flores family has owned and operated several tile businesses in southern California. Joseph Flores owned and operated Majestic Tile from 1970 to 1995; Richard Flores worked for him. Majestic Tile closed in 1995 after Joseph Flores encountered problems with the IRS owing to Majestic’s failure to remit payroll taxes. This case concerns three of the family’s businesses that began operations after Majestic was closed.
In 1995 Richard started a business known as R.C. Construction. Although nominally the owner, Richard had little knowledge about or involvement with the management and finances of R.C. Construction. Riсhard received wages for his work as a tile setter but received no share of the profits. Joseph Flores, who referred to himself as the “operations manager” of R.C. Construction, estimated, bid, and negotiated R.C. Construction’s tile setting contracts as he had Majestic’s before. Priscilla was in charge of R.C. Construction’s finances, as she had been of Majestic’s.
In 1996 R.C. Construction entered into a сollective bargaining agreement (CBA) with the local affiliate of the International Union of Bricklayers and Allied Craftsmen. R.C. Construction thereby agreed to make contributions to the Bricklayers and Trowel Trades International Pension Fund “for each hour worked by all workmen covered by this agreement” - defined to include all tile setters employed by R.C. Construction - until such time as the company gave effective notice of its withdrawal from the CBA. Although R.C. Construction ceased making payments to the Fund in December 1997, and ceased operating in January 1998, it did not then provide the Fund with a notice of withdrawal from the CBA.
Shortly after R.C. Construction ceased operations, Jesse Flores started R.C. Tile. Although Jesse was listed as the owner, he did not have any involvement in the management of the firm; he worked solely as a tile setter. Joseph, who again styled himself the “operations manager,” stated in his deposition that “R.C. Tile was my company.” Priscilla served R.C. Tile, as she had R.C. Construction, as the office manager and bookkeeper. Although there was no written contract between the two companies, R.C. Tile assumed R.C. Construction’s tile setting sub-contracts and corn- *957 pleted jobs R.C. Construction had begun. R.C. Tile did not, however, become a signatory to the CBA or contribute to the Fund.
In 1998 Jesse Flores transferred the assets of R.C. Tile to Priscilla Flores; there was no written contract of sale and apparently no consideration. Priscilla continued to do business under the R.C. Tile name and each member of the Flores family continued to perform his or her job at R.C. Tile.
When R.C. Construction had not made any payments tо the Fund for more than a year, the Trustees of the Fund made unavailing demands upon both R.C. Construction and R.C. Tile. Richard and Priscilla Flores respectively notified the Trustees that R.C. Construction and R.C. The (although not a signatory) were withdrawing from the CBA. ** The Trustees then sued R.C. Construction, R.C. Tile, and Richard and Priscilla Flores under 29 U.S.C. §§ 1132(g)(2) and 1145 to recover the delinquent pension fund payments.
The district court granted the Trustees’ motion for summary judgment. The court concluded from the undisputed material facts that “R.C. Construction and the two R.C. Tile companies are alter egos” and that “it is in the interest of justice to hold that these three successive companies are alter egos.” The appellants moved for reconsideration, which the district court denied, and they now appeal to this court.
II. Analysis
We review the district court’s grant of summary judgment
de novo. See Workman v. Unitеd Methodist Comm. on Relief of the Gen. Bd. of Global Ministries,
The appellants present three arguments for reversing the judgment of the district court: First, the court failed to consider the Declaration of Joseph Flores, which contained materiаl facts in dispute. Second, the court both ignored other facts material to whether R.C. Construction and R.C. Tile were alter egos and applied incorrect legal standards for determining whether an entity is an alter ego under the ERISA. Third, the Trustees are barred by equitable considerations from recovering the delinquent pension contributions.
A. Declaration of Joseph Flores
In its initial decision the district court refused to consider the Declaration of Joseph Flores because it “contradicts Mr. Flores’ deposition testimony at several relevant points.” The court would not allow the Flores to “create a ... factual dispute through the submission of a self-serving declaration that contradicts prior deposition testimony.”
Upon the Flores’ motion for reconsideration, however, the district court did consider the Declaration and found it did not contradict any fact material to whether R.C. Tile was the alter ego of R.C. Construction. Rather, the court stated, the Declaration disputed only “minor and immaterial issues of fact” and did not alter the district court’s conclusion that the Trustees were entitled to summary judgment.
On review, therefore, this court need not consider the merits of the district court’s initial conclusion that the Dеclaration was a “sham affidavit.” The appellants’ pro *958 testation notwithstanding, at the end of the day the district court simply did not ignore Joseph’s Declaration in granting summary judgment to the Trustees.
B. Alter Ego Liability
The Trustees’ claim arises under § 515 of the Multiemployer Pension Plan Amendments Act of 1980 (MPPAA). 29 U.S.C. § 1145. That provision makes a federal obligation of an employer’s contractual commitment to contribute to a multiemployer pension fund:
Every employer who is obligated to make contributions to a multiemployer plan under the terms of the plan or under the terms of a collectively bargained agreement shall, to the extent not inconsistent with law, make such contributions in accordance with the terms and conditions of such plans or such agreement.
Section 515 was a response to the problem сreated when an employer defaults upon its obligation to fund a multiemployer defined-benefit pension plan: If one employer does not make its contributions to such a plan, then the other participating employers must make larger contributions to cover the shortfall.
See, e.g.,
H.R. Rep. No. 96-869 (II) at 15 (1980). The funding burden may be shifted beyond other participating employers to taxpayers
via
the Pensiоn Benefit Guaranty Corporation, and to beneficiaries in the form of reduced pension benefits.
See Upholsterers’ Int’l Union Pension Fund v. Artistic Furniture of Pontiac,
Section 515 “evinces a strong congressional desire to minimize contribution losses and the resulting burden such losses impose upon other plan participants.”
Id.
at 1328. The statute “puts multiemployer plans in a stronger position than they otherwisе occupy under common law contract principles,”
Bakery & Confectionery Union & Indus. Int’l Pension Fund v. Ralph’s Grocery Co.,
Alter ego liability under § 515 further protects the federal interest in the solvency of multiemployer pension plans by enabling ERISA trustees to recovеr delinquent contributions from a sham entity used to circumvent the participating employer’s pension obligations.
See Massachusetts Carpenters Cent. Collection Agency v. Belmont Concrete Corp.,
In order to determine whether two nominally distinct unincorporated businesses are alter egos for the purpose of assessing liability under § 515, we evaluate the similarities between the two enterprises in their ownership, management, business purpose, operations, equipment, and customers.
See Belmont Concrete,
*959
The evidence is overwhelming that R.C. Construction and R.C. Tile had essentially the same ownership, management, business purpose, operations, and customers. They were in the same line of business (tile laying), in the same industry sector (public works constructiоn), in the same geographic area (southern California).
See id.
at 306. Three members of the Flores family successively owned R.C. Construction (Richard) and R.C. Tile (Jesse, then Priscilla). Under each owner, however, the assets and operations of the company were essentially the same. The assets were transferred among them in non-arms length transactions, which provides a “clear foundation for а holding of ‘alter ego’ status.”
Sloan,
All these facts indiсate R.C. Tile is the alter ego of R.C. Construction and therefore liable for that company’s pension obligations as a signatory of the CBA.
See Belmont Concrete,
The appellants’ undocumented assertion that R.C. Tile used different equipment, employees, and accountants than had R.C. Construction and that the two companies obtained different construction contracts does not shake our conviction that they were alter egos. Differences in the contracts and in the employee roster were inevitable because the entities operated successively rather than simultaneously. Such differences as may arise over time following a non-arms length transfer are “not sufficient for a finder of faсt to conclude that the businesses are not ‘alter egos.’ ”
Sloan,
The record also shows the Flores themselves treated R.C. Tile as the alter ego of R.C. Construction. In a letter to a general contractor, Priscilla Flores stated, “R.C. Construction is now doing business as R.C. Tile.” Faxes from Priscilla to suppliers were signed on behalf of “R.C. Construction/R.C. Tile.” Letters and bid notes from Joseph to general contractors identify Joseph’s company аs “R.C. Construc *960 tion/R.C. Tile.” The notice of withdrawal from the CBA stated both R.C. Construction and R.C. Tile were withdrawing, even though R.C. Construction was the only signatory.
Nor did the Flores treat the two businesses as distinct entities in transactions between them.
See Laborers’ Pension Trust Fund v. Sidney Weinberger Homes, Inc.,
The appellants argue R.C. Construction and R.C. Tile cannot be alter egos because “there was no anti-union animus” behind their closing R.C. Construction and establishing R.C. Tile. We shall аssume there was none. As the First Circuit has noted, however, “A finding of anti-union animus is not essential” to hold one entity is the alter ego of another for the purpose of ERISA liability.
Belmont Concrete,
Therefore, based upon the similarities between R.C. Construction and R.C. Tile with respect to management, ownership, business purpose, operations, and customers, and in light of the principals’ complete failure to maintain any meaningful distinction between the two entities, it appears R.C. Construction and R.C. Tile are alter egos.
C. Defenses
Although a favorable balance of the equities is not required to conclude that one entity is the alter ego of another for the purposes of § 515, the appellants present three equitable arguments against holding R.C. Tile liable as the alter ego of R.C. Construction. First, the appellants contend R.C. Tile should not be held the alter ego of R.C. Construction because R.C. Tilе received no economic benefit from its failure to contribute to the Fund. According to the appellants, R.C. Tile was required by California law to, and did, pay its nonunion employees “prevailing wages (which *961 is the same as union scale wages, including trust fund contributions.)”
Even assuming the truth of that assertion - for which the appellants point to no record evidence - such payments do not absolve R.C. Tile of its obligation to make contributions to the Fund pursuant to the CBA.
See Brogan v. Swanson Painting Co.,
Furthermore, even an employer that reсeives no economic benefit from avoiding its obligations does harm to the pension fund, which relies upon contributions (and the investment income thereon) from all signatory employers to finance the defined benefits due to beneficiaries.
See Cent. Pa. Teamsters Pension Fund v. McCormick Dray Line, Inc.,
Second, the appellants argue holding R.C. Tile liable would unjustly enrich the Fund, for which any award of damages would be a windfall. According to the appellants, the Trustees would receive contributions in respect of, but would not incur any obligations to provide pension benefits to, R.C. Tile’s non-union employees.
This is nonsense. R.C. Tile’s decision to employ non-union labor does not diminish the Fund’s defined-benefit obligation to its union beneficiaries. Mirroring that obligation, the Trustees had a clear right under the CBA to receive R.C. Construction’s contributions.
See McCormick Dray Line,
It is not unfair to [the employer] that it be required to contribute to the ... funds after having indirectly paid a comparable amount to other workers, for this is exactly what it contracted to do. Neither would enforcing the contract as written create а “windfall” for the Trustees.
Finally, the appellants argue (under the heading of “waiver”) the Trustees are barred from recovering unpaid pension contributions because they “waited for more than a year” before notifying R.C. Construction and R.C. Tile of their delinquency. The appellants claim they were prejudiced by the delay because R.C. Tile paid out as wages the monies now claimed by the Trustees for the benefit of the Fund. This argument, which is doubtful as a matter of law,
see McCormick Dray Line,
*962 After R.C. Construction ceased making payments to the Fund in December 1997, the Trustees “requested an audit of R.C. Construction’s books and records, pursuant to ERISA and the [CBA], so that it could be determined whether contributions had been made” in full. Declaration of David Stupar, Executive Director of the Fund, at ¶ 12. The Trustees were still trying to get that information when they filed this suit. Upon these facts we cannot say the Trustees were dilatory in notifying the appellants of their delinquency.
III. Conclusion
For the foregoing reasons, the judgment of the district court is
Affirmed.
Notes
This case was considered upon the record from the district court and upon the briefs submitted by parties. See Fed. R.App P. 34(a)(2); D.C.Cir. Rule 34(j).
The notice of withdrawal was dated May 28, 1999. Under the CBA, however, a notice of withdrawal delivered within the 60 days prior to June 1 was not effective until June 1 of the following year.
Different considerations may be relevant where a corporation is involved.
