OPINION OF THE COURT BECKER, Chief Judge. The Worker Adjustment and Retraining Notification Act of 1988 (the WARN Act), 29 U.S.C. § 2101 et seq., mandates that employers provide workers with 60 days’ notice (subject to certain exceptions not at issue in this appeal) prior to a plant closing or mass layoff, and allows various remedies for workers when closures are not preceded by the requisite notification. Because a plant closure often presages a corporation’s demise, leaving workers with no source of satisfaction from their employer, plaintiffs have frequently sought damages from affiliated corporations. In a parallel series of cases, plaintiffs with claims arising from non-WARN Act sources of law against debt-laden or bankrupt corporations have occasionally attempted to sue the corporations’ major secured lenders, on the theory that the lenders have exercised such control over the corporations that veil-piercing is appropriate. This case implicates both lines of precedent. The question before us is whether the former employees of Component Technology (CompTech), a now-defunct company, have set forth sufficient evidence to create a genuine issue of material fact as to whether, under standards we must fashion for this Circuit, CompTech’s major secured lender, General Electric Capital Corporation (GECC), should incur WARN Act liability for CompTech’s unnoticed plant closure. This question, in turn, requires us to consider not only the prerequisites for pareni/subsidiary liability in the WARN Act context (as will be shown, that jurisprudence is apposite here), but also whether the prerequisites change in the context of lender/borrower relationships. The Department of Labor (DOL) has issued a regulation setting forth relevant factors for courts to use when considering whether to impose WARN Act liability on a parent corporation. See 20 C.F.R. § 639.3(a)(2). These factors closely resemble, but do not precisely mirror, the “single employer” or “integrated enterprise” test, frequently utilized for similar purposes in labor and employment law. The Department has also issued a statement explaining its intention that jurisprudence under the WARN Act not deviate from “existing law” with regard to liability for affiliated corporations. See 54 Fed. Reg. 16,045 (Apr. 20, 1989). The tension between “existing law” and the regulatory factors has led to considerable confusion among courts as to the appropriate standards to apply for WARN Act veil-piercing. Compare United Paperworkers Int’l Union v. Alden Corrugated Container Corp., 901 F.Supp. 426, 436-39 (D.Mass.1995), with Wholesale & Retail Food Distrib. Local 63 v. Santa Fe Terminal Servs., Inc., 826 F.Supp. 326, 334-35 (C.D.Cal.1993). To further compound the problem, when it comes to lenders rather than parents in other areas of law, courts have been extremely reluctant to hold lenders liable for their borrowers’ actions; usually, some version of the “alter ego” or “instrumentality” test for liability is used, often with an especial vigor. These tests are far less hospitable to plaintiffs than labor law’s “integrated enterprise” test, and, apparently, than the Department of Labor factors. Thus, the law is presently unsettled as to the proper test for liability under the WARN Act, and as to the significance for WARN Act purposes of an affiliated corporation’s status as “lender” or “parent.” In this case, GECC loaned large sums of money to CompTech, and CompTech fell into default. Exercising its rights under the loan agreements, GECC voted Comp-Tech’s stock and installed a new slate of directors and a new Chief Executive Officer, to whom title of the stock was transferred. For the next few years, GECC and CompTech maintained a close relationship as CompTech struggled to survive as a going concern; when CompTech finally was unable to turn a profit, GECC declined to provide further cash infusions. CompTech, unable to secure new financing, collapsed and shut down its operations without giving WARN Act notice. A class of former CompTech employees have now brought suit against GECC under the WARN Act. We conclude that the appropriate test to employ under the WARN Act for affiliated corporate liabihty is the multi-factored test promulgated by the DOL. We believe that the DOL’s instruction that courts apply “existing law” to questions involving inter-corporate liabihty was not intended to undermine the force of its own regulation on the subject, but was instead intended to instruct courts that existing precedent applying other tests (such as the “integrated enterprise” test) may be useful and appropriate to resolve analogous questions arising under the WARN Act. We also observe that the regulation indicates that the hsted factors are not an exhaustive list, which we interpret as a reminder that the test is one of balancing, and that, as with any balancing test, a number of circumstances not specifically enumerated may be relevant. We must also determine whether GECC’s initial status as a secured lender affects the test we choose to employ for WARN Act liabihty, and we must further decide whether, under the appropriate test, the District Court erred in concluding that plaintiffs had not put forth sufficient evidence to create a genuine issue of material fact as to GECC’s liability. We ultimately hold that because the lines separating “parents” from “lenders” are not often bright ones, the simpler approach is to apply the same test for liability regardless of the formal label the corporations have attached to their association. Our conclusion is strengthened by our recognition that deter mining liabihty by reference to whether a lender has behaved in a “typical” manner, as did the District Court in this case, carries with it the risk of unintentionally altering what is “typical,” as lenders structure their relationships with borrowers to respond to the practices that we ourselves have proclaimed “typical.” Therefore, we take a more functional approach to determining whether or not to “pierce the veil” under WARN by focusing on the nature and degree of control possessed by one corporation over another; in so doing, however, particular weight must be accorded, where applicable, to a lack of ownership interest between corporations. Applying the DOL factors to the circumstances presented in this case, we hold that even if GECC did, in the course of its relationship with CompTeeh, technically become a “parent” corporation, its actions never reached the point where even a more conventional parent would become liable. Therefore, the District Court’s grant of summary judgment to GECC was proper, and we will affirm the judgment. I. Facts and Procedural History Component Technology, a Delaware corporation with headquarters in Erie, Pennsylvania, was a custom injection molder whose business was to manufacture plastic objects in accordance with corporate customers’ specifications, principally in the business machine and medical products markets. R&R Plastics (R&R) was, at that time, a wholly-owned subsidiary of CompTeeh. In June 1989, CompTeeh was poised to enter into a profitable new arrangement with Kodak, whereby CompTeeh would manufacture plastic components for a revolutionary new photocopier. In anticipation of the capital expansion that the venture would require, CompTeeh sought and obtained a $25,000,000 loan from GECC. The loan was formally structured as a loan to the Chicago Plastics Products Corporation (Chicago Plastics), a holding company formed for the purpose of acquiring Comp-Tech. As security for its loan, GECC received pledge agreements for all of the stock in Chicago Plastics, CompTeeh, and R&R, including the right to vote the stock in the event of a default. Shortly after Chicago Plastics purchased CompTech, the Kodak project was canceled due to “technical obsolescence.” CompTech’s business immediately faltered, resulting in default on the GECC loan in 1991. GECC exercised its rights under the pledge agreements and voted its stock to install new boards of directors of the three corporations. The new directors, in turn, chose new corporate officers. On July 10, 1991 GECC hired a consultant with experience in the plastics industry, Thomas Gaffney, to serve as Chief Executive Officer of Chicago Plastics, CompTech, and R&R. At some point in late 1991 or early 1992, GECC Vice-President Jeanette Chen began to manage the CompTech account. In March, she drafted an internal credit memorandum outlining a proposed strategy to restructure CompTech’s loans. The memo explained that for GECC to “[m]ax-imize debt recovery” it would need to “hold[] investment for sufficient time period to implement merger/acquisition strategy, rebuild customer base, and return Company to profitability.” Pursuant to the recommendations contained in the memo, GECC wrote off $20,000,000 of CompTech’s debt and restructured the remaining debt as term loans of $8,500,000, a revolving line of credit of $8,500,000, and nonvoting preferred stock of $4,000,000. GECC then renewed its agreement with Gaffney and arranged for a private foreclosure sale of CompTech’s stock from Chicago Plastics. The stock was sold to Component Technology Acquisition Company (Acquisition), a wholly-owned subsidiary of Component Technology Holdings Corporation (Holdings). Acquisition was then merged into CompTech. Sixty percent of the stock in Holdings was transferred to Gaffney; forty per cent was transferred to Richard Brooks, the newly-appointed president of CompTech. GECC retained a pledge on all of the CompTech common stock, and neither Gaffney nor Brooks paid any compensation for their stock. As part of the consulting agreement, GECC indemnified Gaffney for all liabilities (other than misconduct) arising out of his duties as CEO of the companies and as shareholder of Holdings. As a final step in the restructuring outlined in the Chen memo, CompTech acquired a plastics company known as Accu-form and merged it with R&R. Thus, after these maneuvers, all of CompTech’s stock was owned by a single holding company, Holdings, which, in turn, was owned by Gaffney and Brooks. Gaffney, the CEO of CompTech, was under contract to GECC to run the company, and had been indemnified by GECC for liabilities arising both out of his activities as CEO and his activities as a shareholder. The loan agreement, together with the $4,000,000 worth of nonvoting preferred stock held by GECC, provided GECC with a considerable amount of control over CompTech’s finances. The loan agreement and GECC’s stock ownership entitled GECC to receive certain scheduled payments and, in the event of two consecutive defaults or four defaults overall, to vote in new directors and assume control of CompTech until the deficiency was paid. No dividends could be paid on common stock until GECC had received its preferred payments. Without prior authorization from GECC, CompTech was forbidden to engage in stock reorganization, lending or borrowing, mergers or acquisitions, large-scale capital expenditures, or selling of assets encumbered by liens securing GECC loans. Further, GECC retained the right to approve any employee salaries in excess of $100,000 per year — a restriction apparently intended to enable GECC to monitor the hiring of key personnel. Finally, GECC received warrants on 75% of CompTech’s stock, 24% of which were to be gradually returned to Comp-Tech as the loans were repaid, although there is no indication in the record of when, if ever, the remaining 51% were to be relinquished. As it turned out, Comp-Tech was only able to pay a single dividend to GECC, in 1993, by using monies drawn from the revolving line of credit. As CompTech continued to operate with the new loans in place, GECC exercised continuing oversight of its finances pursuant to the loan agreement, occasionally agreeing to waive penalties and extend further loans to the cash-strapped company. CompTech, in accordance with the agreement, sought approval of a number of its decisions, including executive compensation and benefits, and the sale of equipment. CompTech also provided GECC with updates concerning its financial condition. GECC’s approval was required when CompTech sought to create a Mexican subsidiary to service one of its customers, and in connection with the deal, GECC waived its security interest in relevant equipment, receiving in return a pledge on all of the stock owned by CompTech in the new venture. In early 1994, CompTech sold R&R, and the proceeds of the sale were used to prepay GECC in accordance with the terms of the loan agreement. Later that year, Gaffney wrote to GECC outlining CompTech’s current status and its proposed projects, seeking approval for those proposals relating to the Accuform acquisition. The letter concluded by saying “We need to know what G.E. wants us to do. We are proceeding with items 2, 8 and 4, but we need to get confirmation from G.E. on each one of these items. Obviously, without G.E.’s help we cannot proceed to complete our plans. I am prepared to do whatever G.E. wants relative to Comp-Tech.” The next month, GECC determined that as CEO of CompTech, Gaffney was too focused on “grandiose schemes” for the company and spent too little time on the day-to-day operations. According to the deposition of GECC Vice-President Ed Christie, it was for this reason GECC elected not to renew Gaffney’s contract and asked him to step down as CEO. Gaffney had recently fired Brooks as president and replaced him with Charles Villa; GECC chose to hire Villa as the new president and CEO. In order to transfer power from Gaffney to Villa, both Gaffney and Brooks sold their stock back to Holdings for a nominal price, and Holdings reissued the stock to Villa. Villa then pledged the shares to GECC, and granted GECC the unconditional power to transfer and assign the stock. At some point after the plans for these transfers had been laid, but before the shift in ownership had actually taken place, Villa sent a letter to Chen detailing the current status of CompTech’s attempts to resuscitate its business and requesting GECC’s further support to finance its growth and upgrade its facilities. The letter concluded by stating that “G.E. needs to make decisions now on all the issues outlined in this memo. How you respond will then dictate what the management of COMPTECH will need to do to accomplish the task at hand. We can either move forward in an aggressive, systematic approach to take advantage of industry dynamics and market windows available now or we can remain stagnant and loose [sic] any competitive edge that may exist resulting in a slow death of a one-time INDUSTRY LEADER. The choice is yours to make.” When the stock transfers finally were completed in late June 1994, a number of new rights were granted to GECC. At any time within the first six months, GECC could force Villa to sell his shares to GECC for the same nominal amount that he had paid (the Villa Call). Further, at any time — either before or after the first six months — GECC could force Villa to sell a portion of the stock for value, either to GECC or to a GECC designee (the Bring-Along Call). The purpose of the Villa Call was to enable GECC to “assess Villa’s abilities on a trial basis,” and, should he prove to be unsatisfactory, easily transfer the shares to a new president. The stated purpose of the Bring-Along Call was to allow GECC to sell CompTech if it so chose. Villa, as the stockholder, had the right to vote the shares so long as Comp-Tech stayed current with loan payments; however, it appears that CompTech was in default either at the time of the transfer or shortly thereafter, so that in fact, GECC at all times possessed the voting rights. GECC acknowledged in its internal memo-randa that, as a result of these options, it was potentially responsible for the company’s liabilities under the Employee Retirement Income Security Act of 1974 (ERISA), 29 U.S.C. § 1001 et seq. However, because by this time CompTech had frozen its benefits plans and could not create new ones without GECC approval, there was no risk that GECC would involuntarily become liable for payments under ERISA. Simultaneous with the stock transfer, GECC requested that CompTech hire Stuart Benton as an industry consultant to “help assess the Company’s ongoing cash needs and determine an appropriate account strategy for GECC going forward.” Benton was also to function as a “backup” president should Villa fail to meet GECC expectations. Although Benton was formally under contract to CompTech, several CompTech employees testified in deposition that they understood him to be a GECC representative. Benton observed the CompTech operation for the next few months, until the plant closed. Deposition testimony from CompTech’s upper-level managers demonstrates that although he occasionally made suggestions to the managers, Benton largely worked with Villa and did not direct or interfere with the duties of the other management personnel. None of the upper-level managers, including Villa, reported any attempts by GECC to control CompTech’s operations, through Benton or through anyone else. Other than the financial controls and stock interests described above, GECC had no formal authority to control CompTech’s business decisions, including its strategic planning, its relationships with clients, its marketing, its product selection, its product design, or its quality control. By August 1994, CompTech was contemplating a plant closure, going so far as to contact its attorneys to inquire about its WARN Act obligations. In September 1994, CompTech informed GECC that it would require further cash outlays to continue operations through the end of the year. CompTech also sought financing from Citibank Venture Capital Limited, but Citibank would only provide financing if GECC continued to do so as well. GECC refused to provide further funds, either with or without Citibank’s participation, and, on September 30, Chen drafted an internal memorandum sketching out a proposal for an “orderly liquidation” of the company. Negotiations for Comp-Tech’s liquidation began in October 1994, and on October 14, 1994, employees were formally notified of the plant closing, effective immediately. The former employees of CompTech filed this action against GECC in the District Court for the Western District of Pennsylvania on November 2, 1994. On December 17, 1999, after discovery, the District Court granted GECC’s motion for summary judgment on the ground that the plaintiffs had failed to demonstrate that GECC, as a lender, had “exhibited] such a high degree of control over the debtor corporation” so as to become an “employer” within the meaning of the WARN Act. Pearson v. Component Tech. Corp., 80 F.Supp.2d 510, 518 (W.D.Pa.1999). The court also rejected the plaintiffs’ attempts to argue for veil-piercing liability based on GECC’s status as a parent corporation of CompTech, reasoning that GECC was not a parent and that its actions were “consistent with its role as CompTech’s secured creditor.” Id. at 523. On appeal, the plaintiffs argue that: (1) GECC was an employer within the meaning of the WARN Act as a matter of law by virtue of its ownership of CompTech stock options; and (2) GECC was a parent corporation of CompTech under circumstances justifying veil-piercing under WARN Act standards. The District Court had jurisdiction pursuant to 28 U.S.C. § 1331, and we have jurisdiction pursuant to 28 U.S.C. § 1291. We exercise plenary review over a District Court’s grant of summary judgment. See Coolspring Stone Supply, Inc. v. American States Life Ins. Co., 10 F.3d 144, 146 (3d Cir.1993). We set forth the familiar summary judgment standard in the margin. II. Liability for Affiliated Corporations Under the WARN Act A. Introduction In the wake of numerous plant closings and mergers in the 1970s and 1980s, Congress passed the WARN Act. See Hotel Employees & Rest. Employees Int’l Union Local 54 v. Elsinore Shore Assocs., 173 F.3d 175, 182 (3d Cir.1999). The Act was intended to protect workers by requiring that companies with advance knowledge of an imminent closing provide notice to employees, so as to allow “workers and their families some transition time to adjust to the prospective loss of employment, to seek and obtain alternative jobs and, if necessary, to enter skill training or retraining that will allow these workers to successfully compete in the job market.” 20 C.F.R. § 639.1(a). Thus, the Act states that: An employer shall not order a plant closing or mass layoff until the end of a 60 day period after the employer serves written notice of such an order ... to each representative of the affected employees as of the time of the notice or, if there is no such representative at that time, to each affected employee.... 29 U.S.C. § 2102(a)(1). The Act defines an employer as “any business enterprise” that employs 100 or more employees. Id. § 2101(a). Employers violating the Act are liable for backpay and back benefits. See id. § 2104(a). Thus, the question presented by this litigation is whether, under these facts, GECC was the plaintiffs’ employer. In order to make such a showing, the plaintiffs must establish GECC to be a single “business enterprise” with CompTech such that it is responsible for CompTeeh’s WARN Act obligations. The question when affiliated corporations will be considered a single employer for WARN Act purposes tends to arise in two contexts: (1) when plaintiffs seek to impose liability for violations on affiliates of insolvent corporations, see, e.g., Local 397, Int’l Union of Electronic, Elec. Salaried Mach. & Furniture Workers v. Midwest Fasteners, Inc., 779 F.Supp. 788 (D.N.J.1992); and (2) when plaintiffs seek to establish that two or more affiliated corporations should be viewed as a single enterprise in order to meet the 100 employee WARN Act threshold, see, e.g., Watts v. Marco Holdings, L.P., No. 3:95CV88-B-A, 1997 WL 578783 (N.D.Miss. Aug. 8, 1997). The WARN Act itself does not address such situations, but the Department of Labor regulations issued under the Act provide that: Under existing legal rules, independent contractors and subsidiaries which are wholly or partially owned by a parent company are treated as separate employers or as a part of the parent or contracting company depending upon the degree of their independence from the parent. Some of the factors to be considered in making this determination are (i) common ownership, (ii) common directors and/or officers, (iii) de facto exercise of control, (iv) unity of personnel policies emanating from a common source, and (v) the dependency of operations. 20 C.F.R. § 639.3(a)(2). The five factors will hereinafter be referred to as the “DOL factors.” The Department of Labor’s “supplementary information” regarding its WARN Act regulations explains that: The intent of the regulatory provision relating to independent contractors and subsidiaries is not to create a special definition of these terms for WARN purposes; the definition is intended only to summarize existing law that has developed under State Corporations laws and such statutes as the NLRA, the Fair Labor Standards Act (FLSA) and the Employee Retirement Income Security Act (ERISA). The Department does not believe that there is any reason to attempt to create new law in this area especially for WARN purposes when relevant concepts of State and federal law adequately cover the issue. 54 Fed. Reg. 16,045 (Apr. 20,1989). The intersection of the regulatory factors and the supplementary information has created considerable confusion among courts searching for a single test to determine the status of affiliated corporations. See Cynthia Nance, Affiliated Corporation Liability Under the WARN Act, 52 Rutgers L. Rev. 495, 535-36 (2000) [hereinafter Nance, WARN Act] (describing contradictory holdings). The problem arises because the jurisprudence contains several tests for determining when two corporations compose a single entity depending on whether the cause of action accrues under state or federal law, as well as on the particular type of claim at issue. Further, the DOL factors do not precisely correspond to any of the established tests for such determinations. Courts examining affiliated corporations under the WARN Act have often applied two or more tests, purporting to “average” the results, usually without any systematic method for doing so. See, e.g., United Paperworkers Int’l Union v. Alden Corrugated Container Corp., 901 F.Supp. 426, 436-39 (D.Mass.1995) (conducting, inter alia, a state alter ego test, but ultimately jettisoning the results on the ground that federal liability standards should not turn on state protections for corporations). A further complication comes from the fact that we have before us in this case not the traditional parent/subsidiary relationship but a relationship that began as an arrangement between a secured lender and a borrower — a situation unaddressed by either the Act or the regulations. Thus, we must determine whether the “standard” WARN Act test — whatever test that might be — is even applicable under these circumstances. To that end, we will first briefly sketch some of the methods available for determining intercorpo-rate WARN Act liability, ultimately concluding that rather than simply choosing one of the “established” tests and importing it to the WARN Act context, the appropriate test is the one specifically delineated in the DOL regulation. We further conclude that the supplementary information provided by the Department of Labor was not intended to encourage courts to choose a different test, but was merely intended to clarify that courts may draw on concepts in existing precedent when interpreting and applying the DOL factors. We will then turn to the question whether the DOL factors should apply to situations involving lenders rather than parents, ultimately concluding that the factors should be the same for both. B. Liability Between Parents and Subsidiaries 1. Traditional Veil-Piercing Theories The corporate form was created to allow shareholders to invest without incurring personal liability for the acts of the corporation. These principles are equally applicable when the shareholder is, in fact, another corporation, and hence, mere ownership of a subsidiary does not justify the imposition of liability on the parent. See United States v. Bestfoods, 524 U.S. 51, 69, 118 S.Ct. 1876, 141 L.Ed.2d 43 (1998); American Bell Inc. v. Federation of Tel. Workers of Pa., 736 F.2d 879, 887 (3d Cir.1984). Nor will liability be imposed on the parent corporation merely because directors of the parent corporation also serve as directors of the subsidiary. See Bestfoods, 524 U.S. at 69, 118 S.Ct. 1876. However, under both state and federal common law, abuse of the corporate for m will allow courts to employ the “tool of equity” known as veil-piercing, i.e., disregard of the corporate entity to impose liability on the corporation’s shareholders. Publicker Indus., Inc. v. Roman Ceramics Corp., 603 F.2d 1065, 1069 (3d Cir.1979). Courts have held veil-piercing to be appropriate “when the court must prevent fraud, illegality, or injustice, or when recognition of the corporate entity would defeat public policy or shield someone from liability for a crime,” Zubik v. Zubik, 384 F.2d 267, 272 (3d Cir.1967), or when “the parent so dominated the subsidiary that it had no separ-rate existence,” New Jersey Dep’t of Envtl. Prot. v. Ventron Corp., 94 N.J. 473, 468 A.2d 150, 164 (1983). The Third Circuit alter ego test is fairly typical of the genre. It requires that the court look to the following factors: gross undercapitalization, failure to observe corporate formalities, nonpayment of dividends, insolvency of debtor corporation, siphoning of funds from the debtor corporation by the dominant stockholder, nonfunctioning of officers and directors, absence of corporate records, and whether the corporation is merely a facade for the operations of the dominant stockholder. See American Bell, 736 F.2d at 886. Other (similar) formulations are set forth in the margin. The test, whether or not a particular version requires an element of fraudulent intent, see supra note 2, is demonstrably an inquiry into whether the debtor corporation is little more than a legal fiction. Such a burden is notoriously difficult for plaintiffs to meet. For instance, courts have refused to pierce the veil even when subsidiary corporations use the trade name of the parent, accept administrative support from the parent, and have a significant economic relationship with the parent. See, e.g., Jackson v. General Elec. Co., 514 P.2d 1170 (Alaska 1973). Thus, in order to succeed on an alter ego theory of liability, plaintiffs must essentially demonstrate that in all aspects of the business, the two corporations actually functioned as a single entity and should be treated as such. See RRX Indus., Inc. v. Lab-Con, Inc., 772 F.2d 543, 545 (9th Cir.1985) (veil-piercing is appropriate when “the personalities of the corporation and individual are no longer separate”); Akzona Inc. v. E.I. Du Pont De Nemours & Co., 607 F.Supp. 227, 237 (D.Del.1984) (a subsidiary is an alter ego or instrumentality of the parent when “the separate corporate identities ... are a fiction and ... the subsidiary is, in fact, being operated as a department of the parent”). 2. “Integrated Enterprise” Test Veil-piercing doctrine has been criticized for employing the same formulations of the test across the different contexts in which plaintiffs seek to impose liability. See Phillip I. Blumberg, The Law of Corporate Groups: Substantive Law § 6.01, at 107-OS (1987); cf. William H. Lawrence, Lender Control Liability: An Analytical Model Illustrated with Applications to the Relational Theory of Secured Financing, 62 S. Cal. L. Rev. 1387, 1388 (1989) [hereinafter Lawrence, Lender Control Liability] (criticizing the use of similar “indicia of control” for lender liability cases regardless of context). It is often argued that because public policy varies from contract to tort to property, for example, veil-piercing standards should vary as well. See, e.g., Robert B. Thompson, Piercing the Corporate Veil: An Empirical Study, 76 Cornell L. Rev. 1036 (1991). These concerns have been partially addressed through the “integrated enterprise” test for the presence of a single employer, a sort of labor-specific veil-piercing test, first developed by the National Labor Relations Board. Because the Board was concerned only with labor law and policy, it developed a test for corporate “sameness” that, likewise, concerned itself only with those aspects of corporations having a direct relevance to labor relations. So, for example, the integrated enterprise test is not concerned with such traditional alter ego hallmarks as “nonpayment of dividends,” because such aspects of a corporation’s finances are not as directly related to management’s labor policy as are other aspects of corporate functioning. See Nance, WARN Act, supra, at 533. Rather, the test looks to four labor-related characteristics of affiliated corporations: interrelation of operations; common management; centralized control of labor relations; and common ownership or financial control. See, e.g., Radio & Television Broad. Techs. Local Union 1264 v. Broadcast Serv. of Mobile, 380 U.S. 255, 256, 85 S.Ct. 876, 13 L.Ed.2d 789 (1965) (per curiam). No single factor is dispositive; rather, single employer status under this test “ultimately depends on all the circumstances of the case.” NLRB v. Browning-Ferris Indus. of Pa., Inc., 691 F.2d 1117, 1122 (3d Cir.1982). As originally designed, the integrated enterprise test was used by the National Labor Relations Board to determine whether two firms were sufficiently related to meet its jurisdictional minimum amount of business volume. See Stephen F. Befort, Labor Law and the Double-Breasted Employer: A Critique of the Single Employer and Alter Ego Doctrines and a Proposed Reformulation, 1987 Wis. L. Rev. 67, 75. Later, the Board came to use the same test to determine whether nominally separate firms constituted “neutral” entities in the context of secondary boycotts, and to determine whether an employer had impermissibly “double-breasted” operations so as to avoid the obligations of a collective bargaining agreement. See id. at 75-76. Since its initial formulation, the test has been applied by courts in other employment contexts, including the Labor Management Relations Act, see International Bhd. of Teamsters Local 952 v. American Delivery Serv. Co., Inc., 50 F.3d 770 (9th Cir.1995); Title VII and the Age Discrimination in Employment Act, see Frank v. U.S. West, Inc., 3 F.3d 1357 (10th Cir.1993); the Americans with Disabilities Act, see EEOC v. Chemtech Int’l Corp., 890 F.Supp. 623 (S.D.Tex.1995); and the Fair Labor Standards Act, see Takacs v. Hahn Auto. Corp., No. C-3-95-404, 1999 WL 33117265 (S.D.Ohio Jan. 4, 1999). But see Papa v. Katy Indus., Inc., 166 F.3d 937, 940-43 (7th Cir.1999) (rejecting the integrated enterprise test in the context of antidiscrimination law). Department of Labor regulations have also adopted the integrated enterprise test for the Family Medical Leave Act. See 29 C.F.R. § 825.104(c)(2). The integrated enterprise test, with its focus only on labor relations and its emphasis on economic realities as opposed to corporate formalities, see Phillip I. Blum-berg, The Law of Corporate Groups: Problems of Parent and Subsidiary Corporations Under Statutory Law of General Application § 13.03, at 398 (1989), is demonstrably easier on plaintiffs than traditional veil piercing. Ultimately, “the policy underlying the single employer doctrine is the fairness of imposing liability for labor infractions where two nominally independent entities do not act under an arm’s length relationship.” Murray v. Miner, 74 F.3d 402, 405 (2d Cir.1996). 3. Direct Liability Although not often employed to hold parent corporations liable for the acts of subsidiaries in the absence of other hallmarks of overall integration of the two operations, it has long been acknowledged that parents may be “directly” liable for their subsidiaries’ actions when the “alleged wrong can seemingly be traced to the parent through the conduit of its own personnel and management,” and the parent has interfered with the subsidiary’s operations in a way that surpasses the control exercised by a parent as an incident of ownership. United States v. Bestfoods, 524 U.S. 51, 64, 118 S.Ct. 1876, 141 L.Ed.2d 43 (1998) (quoting William O. Douglas & Carrol M. Shanks, Insulation from Liability Through Subsidiary Corporations, 39 Yale L.J. 193, 207 (1929)). In such situations, the parent has not acted on its own (in which case there would be no need even to consider the subsidiary’s actions), nor has it acted in its capacity as owner of the subsidiary; rather, it has forced the subsidiary to take the complained-of action, in disregard of the subsidiary’s distinct legal personality. See Esmark, Inc. v. NLRB, 887 F.2d 739, 756-57 (7th Cir.1989). Thus, in the labor context, “direct” liability may attach if the parent has overridden the subsidiary’s ordinary decision-making process and ordered it to institute an unfair labor practice, or to create discriminatory hiring policies. See id. at 757. In this way, direct liability functions essentially as a kind of “transaction-specific” alter ego theory. Id. at 756. Although direct liability is rarely used independently to hold parents liable for them subsidiary’s actions, it has often been used in conjunction with the “integrated enterprise” test for liability, particularly to satisfy the “control of labor” prong. For instance, the Ninth Circuit in UA Local 313 of the United Ass’n of Journeymen & Apprentices of the Plumbing & Pipefitting Industry of the United States & Canada v. Nor-Cal Plumbing, Inc., 48 F.3d 1465 (9th Cir.1994), held that the “control of labor” prong of the integrated enterprise test may be established either by a showing of day-to-day control of labor, or by a showing that the parent was specifically responsible for the labor practice at issue in the litigation. See id. at 1471. Other courts have explained that all four factors of the integrated enterprise test are to be employed solely with an eye to discerning which entity — the parent or the subsidiary — was the final decisionmaker for the challenged practice. See, e.g., Hukill v. Auto Care, Inc., 192 F.3d 437, 444 (4th Cir.1999); Lusk v. Foxmeyer Health Corp., 129 F.3d 773, 777 (5th Cir.1997). Thus, the “directness” of a parent’s involvement in the employment decision under dispute may be conceived as a sliding scale; if the parent has sufficiently overwhelmed its subsidiary in taking the challenged action, such a showing is sufficient to create liability; if the parent was involved to a lesser degree, there must be some demonstration of the presence of the other aspects of the integrated enterprise test. 4. Choosing a Test for WARN Liability Given these variations in the methods by which courts determine when corporations shall be liable for the acts of their affiliates, it is not surprising that there has been a good deal of inconsistency among the courts attempting to apply “existing law” in the context of the WARN Act. In the first reported case on the subject, Local 397, International Union of Electronic, Electrical Salaried Machine & Furniture Workers v. Midwest Fasteners, Inc., 779 F.Supp. 788 (D.N.J.1992), the court employed three different tests — Third Circuit federal veil-piercing, the integrated enterprise test, and the DOL factors — to determine whether parent and grandparent corporations could be held liable for the debts of a subsidiary. The court concluded that the corporations were separate under an “alter ego” analysis, but identical under integrated enterprise analysis and the DOL factors. In reconciling these different outcomes, the court ultimately explained that the WARN Act was enacted to protect workers, and that the “wrongdoer” should not escape liability merely because “corporate formalities” were observed — a principle that the court noted had been established in federal labor statutes generally. Id. at 800. Thus, the court held that the outcomes of the integrated enterprise and DOL factors would control the analysis, rendering its entire discussion of alter ego not only superfluous, but also inapposite. Other courts have followed the multi-part Midwest Fasteners approach, although the application of its principles varies widely. For instance, in Watts v. Marco Holdings, L.P., No. 3:95CV88-B-A, 1997 WL 578783 (N.D.Miss. Aug. 8, 1997), the court chose to apply state, rather than federal, veil-piercing analysis, all the while acknowledging that, as Midwest Fasteners had stated, for the purpose of determining whether two nominally separate companies constituted a single employer, state law veil-piercing was probably inappropriate. See id. at *2; see also United Paperworkers Int'l Union v. Alden Corrugated Container Corp., 901 F.Supp. 426, 436-39 (D.Mass.1995) (applying state corporate law, integrated enterprise, and the DOL factors and concluding that because WARN is a federal labor statute, the outcomes of the federal tests, rather than the state alter ego test, should control). On the opposite end of the spectrum, the court in Wholesale & Retail Food Distribution Local 63 v. Santa Fe Terminal Services, 826 F.Supp. 326 (C.D.Cal.1993), also applying state alter ego principles, rejected the plaintiffs’ assertions that state veil-piercing was less important under WARN than the DOL factors, and chose not to employ the integrated enterprise test at all. See id. at 334-35. In United Mine Workers of America, District 2 v. Florence Mining Co., 855 F.Supp. 1466 (W.D.Pa.1994), the court, although purporting to follow Midwest Fasteners, actually appeared to apply only the DOL factors in concluding that two corporations did not constitute a single employer for WARN Act purposes. See id. at 1480. Finally, in International Brotherhood of Teamsters Local 952 v. American Delivery Service, 50 F.3d 770 (9th Cir.1995), the Ninth Circuit expressed doubts about the need to apply several different tests for liability, yet still chose to apply both the integrated enterprise test and the DOL factors, albeit concurrently due to the tests’ similarity. See id. at 776. The current trend toward applying more than one test for affiliated corporate liability is manifestly unworkable. Not only does this approach generate considerable uncertainty for parties affected by the WARN Act (the briefs presented to us are exemplars; they spend an inordinate amount of time simply running through different possible tests for liability), but it also obfuscates the purposes of the inquiry itself, i.e., whether the affiliated corporation should be legally responsible for issuing WARN notice. Further, although the importation of state law standards into federal law is permissible when state law is deemed to effectuate federal policy, see Textile Workers Union of Am. v. Lincoln Mills of Ala., 353 U.S. 448, 457, 77 S.Ct. 912, 1 L.Ed.2d 972 (1957), state veil-piercing standards hardly seem likely to do so when such standards may generate inconsistency in an area of law that has always been characterized by insistence on uniformity. Cf. Antol v. Esposto, 100 F.3d 1111, 1115 (3d Cir.1996) (discussing the need for uniformity in the interpretation of collective bargaining agreements). The use of state law standards also has the potential to permit “[t]he policy underlying a federal statute” to be “defeated by ... an assertion of state power.” Anderson v. Abbott, 321 U.S. 349, 365, 64 S.Ct. 531, 88 L.Ed. 793 (1944). Finally, the multitest approach is both “unduly complicated,” American Delivery Serv., 50 F.3d at 776, and ultimately yields no definitive answer to the question of liability: When liability is uncertain enough to result in different outcomes for each of the different tests, there is no method of reconciling the results, much in the same way that a man with one watch always knows what time it is, but a man with two watches is never sure. Cf. Papa v. Katy Indus., Inc., 166 F.3d 937, 940 (7th Cir.1999) (criticizing the integrated enterprise test on the ground that there is no way to reconcile the results of the prongs). Given these variations in the methods by which courts determine when corporations shall be liable for the acts of their affiliates, we decline to interpret the Department of Labor’s statement that it does not intend to create “new” law for WARN Act liability as a direction to courts to employ multiple tests within a single case. Rather, we conclude that the most prudent course is to employ the factors listed in the Department of Labor regulations themselves. This approach not only has the virtue of simplicity (if anything in this area of law can be described as “simple”), but also allows for the creation of a uniform standard of liability for the enforcement of a federal statute. Cf. United States v. Pisani, 646 F.2d 83, 87-88 (3d Cir.1981) (holding that federal veil-piercing standards are appropriate in Medicare disputes due to the need for a uniform federal approach). Finally, and most importantly, the DOL factors are the best method for determining WARN Act liability because they were created with WARN Act policies in mind and, unlike traditional veil-piercing and some of the other theories, focus particularly on circumstances relevant to labor relations. The DOL factors are quite similar to the integrated enterprise test, which is understandable because the integrated enterprise test was also specifically intended to deal with labor relations. However, in addition to those factors that are analogous to the integrated enterprise factors, the Department of Labor’s version has included a fifth, catch-all factor — that of “de facto exercise of control” — that has the potential to tip the balance in an otherwise close case. This factor is arguably problematic, because read in isolation, it might well encourage the imposition of liability merely as a result of the control ordinarily exercised by a parent corporation over a subsidiary by virtue of its ownership. Such a result would cause a type of liability that is not only at odds with the purpose of limited liability in general, but also would be inconsistent with the “existing legal rules” regarding parental liability that the Department of Labor would have courts apply. See Bestfoods, 524 U.S. at 61-62, 118 S.Ct. 1876 (describing as “horn-book” law that a parent’s exercise of control through ownership of stock is not grounds for holding the parent hable for the subsidiary’s actions). In reconciling this apparent tension, we observe that the DOL factors are, by their wording, more focused than their integrated enterprise test counterparts. For instance, rather than looking to “centralized control of labor relations” — the factor that, in the integrated enterprise context, could be satisfied either upon a showing that the parent and subsidiary functioned as a single entity, or, alternatively, upon a showing that the parent directed the subsidiary to institute the policy at issue — the DOL formulation is “unity of personnel policies,” a rendering that appears to be more targeted toward discerning whether the nominally separate corporations actually functioned as a single entity with respect to such policies on a regular, day-to-day basis. Similarly, the “common management” prong of the integrated enterprise test, which allowed courts to focus not only on employees holding formal officer positions or directorships but also on employees occupying supervisory positions, see, e.g., Hukill v. Auto Care, Inc., 192 F.3d 437, 443 (4th Cir.1999); Penntech Papers, Inc. v. NLRB, 706 F.2d 18, 25-26 (1st Cir.1983), has been changed to “common officers and/or directors,” a facially more specific requirement. In light of these changes, and in light of the instruction that the test should draw upon existing legal rules, we read the “de facto exercise of control” factor as an endorsement of the sort of hybrid direct liability analysis heretofore employed in the context of the integrated enterprise test — allowing consideration not only of whether the two corporations shared the same labor policies, as the DOL’s “unity” factor would suggest, but also of whether the parent company directly exercised control over the particular policy at issue. We further conclude that the regulation’s specific instruction that the “factors” are a nonexhaustive list is meant only as a reminder that the inquiry is a balancing test, and that, as with most balancing tests, a number of circumstances may be relevant. Just as the integrated enterprise test is often described as ultimately an inquiry into whether the two companies operated at arm’s length, see NLRB v. Browning-Ferns Indus. of Pa., Inc., 691 F.2d 1117, 1122 (3d Cir.1982), we believe that the Department of Labor’s instructions are intended to allow the consideration of evidence that might otherwise fall outside of the listed factors in order to conduct such an inquiry. 5. Conclusion In the long history of the corporate form and limited liability, both the common law and various pieces of legislation have developed numerous methods for determining when affiliated corporations should be treated as unified or as distinct entities. These methods are often quite different from each other, and vary across contexts. In light of this history, if we were to interpret the DOL’s instruction that courts apply “existing law” to determine WARN Act liability for affiliated corporations as a literal direction to employ the various tests that have been developed over the years, we would find ourselves ensnared in a web of complicated — and conflicting — lines of jurisprudence. We cannot believe that the Department intended such a result. Rather, in our view, the Department intended for courts to test for affiliated corporate liability under WARN along the dimensions specifically enumerated in its regulation. These dimensions, in turn, were adapted from other tests developed for intercorporate liability, most notably labor law’s “integrated enterprise” test. In light of the similar considerations inherent in the DOL factors and in other such “veil-piercing” tests, we believe that the DOL’s instruction that courts apply “existing law” is intended only to encourage courts to make use of established precedent in interpreting and applying its factors. Further, via its statement that the factors are meant as a nonexhaustive list, the DOL has made room for the exercise of the flexibility that this area of law requires. Accordingly, in determining whether two or more corporations constitute a single “employer,” the factfinder may consider not only the aspects of corporate organization specifically listed in the regulation, but also may consider the other indicia of corporate “sameness” that have characterized this area of the law, such as nonfunctioning of officers and directors, gross undercapitalization, and other circumstances that demonstrate a lack of an arm’s-length relationship between the companies. We also interpret the DOL’s inclusion of the “de facto exercise of control” factor to be an endorsement of the hybrid direct liability analysis heretofore employed in the context of the integrated enterprise test. Thus, the “de facto exercise of control” prong allows the factfinder to consider whether the parent has specifically directed the allegedly illegal employment practice that forms the basis for the litigation. C. Lender Liability Under the WARN Act 1. Discussion The preceding discussion focused on the standards to be employed for parent/subsidiary liability (or between sister corporations). But at the time their venture began, GECC was a major secured lender of CompTech, and not a parent. Neither the WARN Act itself, nor the regulations, explicitly discuss the statute’s applicability to lenders, but we agree with both the Eighth and the Ninth Circuits that, under some circumstances, a lender can become so entangled with its borrower’s affairs so as to engender WARN Act liability. See Adams v. Erwin Weller Co., 87 F.3d 269, 271 (8th Cir.1996); Chauffeurs, Sales Drivers, Warehousemen & Helpers Union Local 572 v. Weslock Corp., 66 F.3d 241, 244 (9th Cir.1996). Thus, the question becomes what circumstances must exist before such liability can attach. Courts have grappled with the question of lender liability in a wide variety of situations, such that the catch-phrase “lender liability” has now taken on a broad meaning to refer to any kind of liability that can grow out of the lender/borrower relationship. See, e.g., Lawrence, Lender Control Liability, supra (describing various theories under which lenders can be held liable either to their borrowers or to third parties). For our purposes, the most relevant lines of precedent are those where third parties seek to impose liability on major lenders on the theory that the lenders have so controlled the borrowing corporation that the corporation was functionally being run by the lenders, or solely for the lenders’ benefit, to the detriment of other creditors. See, e.g., Krivo Indus. Supply Co. v. National Distillers & Chem. Corp., 483 F.2d 1098 (6th Cir.1973). Often, these claims arise in the context of a bankruptcy proceeding, whereby the creditors or the trustee seek equitable subordination of the major lender’s claims. See, e.g., In re W.T. Grant Co., 699 F.2d 599 (2d Cir.1983). In other situations, creditors simply sue the major lender on the theory that the lender’s control over the borrower rendered the lender the real party in interest for the incurred debt. See, e.g., Combustion Sys. Servs., Inc. v. Schuylkill Energy Res., Inc., Civ.A. 92-4228, 1993 WL 514496 (E.D.Pa. Dec.1, 1993). In these situations, the test usually applied is some version of traditional veil-piercing, be it alter ego, instrumentality, or some other formulation. See, e.g., In re Clark Pipe & Supply Co., Inc., 893 F.2d 693, 699 (5th Cir.1990) (explaining that, in the absence of fraud, a lender must have used its debtor as an instrumentality to justify equitable subordination); Great West Cas. Co. v. Travelers Indem. Co., 925 F.Supp. 1455, 1462-63 (D.S.D.1996) (utilizing state veil-piercing standards to determine whether a lender would be liable to a third party for the debtor’s debts). This is precisely the test that was employed by the District Court when it concluded that because GECC was a lender and not a parent, the integrated enterprise test was inapplicable. See Pearson v. Component Tech. Corp., 80 F.Supp.2d 510, 520 (W.D.Pa.1999). We believe, however, that traditional lender/borrower veil-piercing jurisprudence is inappropriate in the WARN Act context for many of the same reasons that we rejected such jurisprudence in the context of parent/subsidiary liability. To begin with, the precedent on this point does not draw as sharp a distinction between “lenders” and “parents” as the District Court perceived. Although Krivo and its progeny employed strict veil piercing standards to suits against lenders, they did so in situations where even parents would have been examined under such standards. The only differences between parents and lenders came in the test’s application, both via the court’s awareness of the changed context, see Krivo, 483 F.2d at 1110 (observing that the lender’s “control” was limited to its financial interest as a major creditor), and the court’s statement that the lack of stock ownership is “a factor to be considered in assessing the relationship between two companies,” see id. at 1109; see also Riquelme Valdes v. Leisure Res. Group, Inc., 810 F.2d 1345, 1353 (5th Cir.1987) (explaining that complete ownership is a “symptom but not the sine qua non of alter ego status”). It follows that when the appropriate test for parental liability is something other than the strict alter ego test, there should be a parallel change in the test for liability for lenders. Further, traditional veil-piercing jurisprudence tends to sweep quite broadly, allowing liability to attach only when there is complete unity of identity in all aspects of corporate functioning. See, e.g., Krivo, 483 F.2d at 1105 (liability attaches to lenders only when there has been “total control” over the debtor). Although such an inquiry may be appropriate for many types of claims, the mere existence of the integrated enterprise test demonstrates that in the labor context, a more targeted inquiry is appropriate. We acknowledge that the DOL factors are explicitly made applicable in the WARN Act regulation only to “subsidiaries” and not to borrowers, but do not read that reference as precluding the application of the factors to lenders; rather, we believe that by directing courts to examine these particular factors, the Department of Labor was highlighting those aspects of corporate functioning that are most closely tied to the particular problems the WARN Act was intended to address. Additionally, the problem with creating such a sharp distinction in liability rules under the WARN Act for lenders and for parents is that it will not always be clear when a party should be characterized as a “lender,” when a party should be characterized as a parent or owner, and when a party occupies both roles. In the case before us, GECC began its relationship with CompTech as a lender, but subsequently foreclosed on the stock and, rather than merely holding the stock for only a few days before the plant closure (as was the case in Weslock), transferred it (for no consideration) to CompTech’s Chief Executive Officer (then under contract to GECC), yet retained a considerable amount of control over the stock for the next several years as part of its plan to “hold” CompTech until the company could be restored to profitability. Given the ease with which Thomas Gaffney parted with the stock upon being asked by GECC to relinquish his position with CompTech, it is certainly not clear that GECC should not be viewed as having owned Comp-Tech’s stock from the date of foreclosure until the date that the company was finally liquidated. Lenders may also occasionally be difficult to distinguish from parents because, although generally the difference between a “parent” and a “lender” is the existence of an equity, rather than a debt, interest in the company, lenders often structure their interests in hybrid ways. In this case, in addition to traditional loans, GECC chose to structure part of the debt by having CompTech modify its articles of incorporation so as to create a class of mandatorily redeemable preferred stock tailored to GECC’s interest. Such redeemable preferred stock is currently listed as neither equity nor liability according to U.S. generally accepted accounting principles. See International Accounting Standards, SEC Release Nos. 33-7801 & 34-42430, 65 Fed. Reg. 8,896, 8,911 (Feb. 23, 2000). However, it is sometimes classified as equity in SEC opinions, see, e.g., The Southern Company, SEC Release Nos. 35-27323 & 70-8277, 2000 SEC LEXIS 2860 (Dec. 27, 2000), although international accounting standards list such stock as a liability, see International Accounting Standards, supra, and federal regulations forbid such stock from being listed as stockholders’ equity, see 17 C.F.R. § 210.5-02. See generally Anthony P. Polito, Useful Fictions: Debt and Equity Classification in Corporate Tax Law, 30 Ariz. St. L.J. 761 (1998) (explaining the fluidity of the concepts of “debt” and “equity”). Several federal statutes have defined the term “parent” in such a way as to include GECC’s interest. For instance, the Internal Revenue Code at 26 U.S.C. § 1563 defines as “parents” in a controlled group those companies that own eighty percent of the of the stock of other corporations in the group, and 26 U.S.C. § 1202 requires only fifty percent ownership. Ownership, in turn, is defined throughout the Code to include stock options. See, e.g., 26 U.S.C. §§ 318, 544, 554, 1563. Under these definitions, GECC was a parent of CompTech after the transfer to Charles Villa, because GECC retained options on all of Comp-Tech’s stock. The Code of Federal Regulations also contains definitions of “parent” and “subsidiary” that would include GECC’s relationship to CompTech as a result of its power to vote the stock in the wake of CompTech’s default. See 17 C.F.R. § 210.1-02. And Pennsylvania law defines the term “subsidiaries” for registered corporations as including those corporations for which another corporation has obtained options on fifty percent of the voting stock, see 15 Pa. Cons.Stat. § 2542, a definition that would also apply to GECC due to its calls obtained during the stock transfer to Villa. That the Supreme Court of Delaware described the right to vote a majority of the board in the event of default as a “creditor’s remedy” in In re Bicoastal Corp., 600 A.2d 343, 350 (Del.1991), merely selves to highlight the hybrid nature of such rights. Obviously, however, the regulatory purposes of these statutes (and the WARN Act itself) vary considerably. Finally, we note that the commonly understood difference between a “parent” and a “lender” — i.e., the existence of an equity interest — is largely accounted for in the DOL factors themselves, via the “common ownership” prong. Although this factor is typically referred to as the “least important” of the factors, International Bhd. of Teamsters Local 952 v. American Delivery Serv., 50 F.3d 770, 775 (9th Cir.1995), these statements mean only that, by itself, ownership — and even ownership coupled with common management — is not a sufficient basis for liability, see Lusk v. Foxmeyer Health Corp., 129 F.3d 773, 778 (5th Cir.1
