The issue in this case is whether severance and seniority provisions are bona fide fringe benefits required to be included in wage determinations issued by the Secretary of Labor pursuant to the Service Contract Act of 1965, 41 U.S.C. § 351 et seq.
I. THE STATUTE
The Service Contract Act requires the inclusion of specific provisions in every contract entered into by the United States in excess of $2500 (with certain exceptions not applicable here)1 “the principal purpose of which is to furnish services in the United States through the use of service employees.” 2 A contract subject to the § 351(a) requirements must contain, for example, “a provision specifying the minimum monetary wages to be paid the various classes of service employees in the performance of the contract or any subcontract thereunder.”3 This amount is to be determined by the Secretary of Labor “in accordance with prevailing rates for such employees in the locality, or, where a collective bargaining agreement covers any such service employees, in accordance with the rates for such employees provided for in such agreement, including prospective wage increases provided for in such agreement as a result of *1253arm’s length negotiations.” 4 In no event can these “minimum monetary wages” be lower than the federal minimum wage.5
This case focuses on the Act’s requirement that all service contracts covered by the Act include a provision specifying the fringe benefits to be furnished the various classes of service employees. This subsection requires that a contract covered by the Act contain:
(2) A provision specifying the fringe benefits to be furnished the various classes of service employees, engaged in the performance of the contract or any subcontract thereunder, as determined by the Secretary or his authorized representative to be prevailing for such employees in the locality, or, where a collective-bargaining agreement covers any such service employees, to be provided for in such agreement, including prospective fringe benefit increases provided for in such agreement as a result of arm’s-length negotiations. Such fringe benefits shall include medical or hospital care, pensions on retirement or death, compensation for injuries or illness resulting from occupational activity, or insurance to provide any of the foregoing, unemployment benefits, life insurance, disability and sickness insurance, accident insurance, vacation and holiday pay, costs of apprenticeship or other similar programs and other bona fide fringe benefits not otherwise required by Federal, State, or local law to be provided by the contractor or subcontractor. The obligation under this sub-paragraph may be discharged by furnishing any equivalent combinations of fringe benefits or by making equivalent or differential payments in cash under rules and regulations established by the Secretary.
41 U.S.C. § 351(a)(2). This section must be read with a 1972 amendment which provides that no contractor who succeeds to a contract subject to the Act and provides substantially similar services shall pay any service employee less than the wages and fringe benefits to which he would have been entitled if employed under the predecessor’s contract. This part of the Act provides:
(c) No contractor or subcontractor under a contract, which succeeds a contract subject to this chapter and under which substantially the same services are furnished, shall pay any service employee under such contract less than the wages and fringe benefits, including accrued wages and fringe benefits, and any prospective increases in wages and fringe benefits provided for in a collective-bargaining ágreement as a result of arm’s-length negotiations, to which such service employees would have been entitled if they were employed under the predecessor contract: Provided, That in any of the foregoing circumstances such obligations shall not apply if the Secretary finds after a hearing in accordance with regulations adopted by the Secretary that such wages and fringe benefits are substantially at variance with those which prevail for services of a character similar in the locality.
41 U.S.C. § 353(c).
It was the intent of Congress that the Secretary of Labor make determinations of the minimum monetary wages and fringe benefits for the various classes of service employees working under contracts covered by the Act.6 Thus, any wage determination issued must contain the wage and fringe benefit provisions of any collective bargaining agreement between the incumbent employer and any union representing the service employees to the extent that sections 351(a)(1) and 351(a)(2) require their inclusion. The successor contractor must pay the wages and provide the benefits unless “the Secretary finds after a hearing . that such wages and fringe benefits are substantially at variance with those which prevail for services of a character *1254similar in the locality.” 7 The Secretary is also empowered to “provide such reasonable limitations and . . . make such rules and regulations allowing reasonable variations, tolerances, and exemptions” from the provisions of the Act, “but only in special circumstances where he determines that such limitation, variation, tolerance, or exemption is necessary and proper in the public interest or to avoid the serious impairment of government business, and is in accord with the remedial purpose of this chapter to protect prevailing labor standards.”8 The Secretary of Labor has also issued regulations to implement the Act.9
II. BACKGROUND
The material facts of this case are not disputed. Trinity Services, Inc. (“Trinity”) is a service contractor holding two janitorial service contracts, one at Patrick Air Force Base and the other at Cape Canaveral Air Force Station. To perform these contracts, Trinity employed members of the Transport Workers International Union (“TWIU”) and Service Employees International Union (“SEIU”), and entered into collective bargaining agreements with their respective locals. Trinity’s contracts were due to expire on November 30, 1976; therefore, the Air Force filed with the Department of Labor notices of its intentions to enter into new contracts.10 On October 22, 1976, in accordance with these notices and 29 C.F.R. § 4.3,11 the Department of Labor issued Wage Determination No. 73-794 for the Patrick Air Force Base contract12 and Wage Determination No. 73-535 for the Cape Canaveral contract.13 The Secretary’s wage determinations, as required by the Act, specify the minimum monetary wages and fringe benefits to which all bid and contracts accepted by the Government must conform.
The services to be furnished under the new contracts for which bidding was opened would be substantially the same as the services previously being performed by Trinity. The wage rates and fringe benefits paid by Trinity to its service employees were contained in the two collective bargaining agreements entered into on August 13, 1976 between Trinity and the two unions.14 Thus, according to the statute and the applicable regulations,15 the Secretary was required to issue wage determinations for the successor contracts which set forth for the various classes of employees the wage rates and fringe benefits contained in the existing collective bargaining contract, and the wage determinations did include most of the wage and fringe benefits included in the agreements.
This dispute arises primarily because each wage determination excluded a severance pay provision, which required the successor contractor to make a payment to employees of the predecessor contractor which it did not hire:
*1255The provision set forth in Section 10, Article 26 (Severance Allowance), of the predecessor contractors [sic] collective bargaining agreement is deemed outside the perveiw [sic] of the obligations imposed on a successor contractor under Sections (2)a [2(a)] [41 U.S.C. § 351(a)] and 4(c) [41 U.S.C. § 353(c)] of the Service Contract Act.
J.A. 12, 18. The excluded provision of the collective bargaining agreements, Art. 26, § 10, provided as follows:
It is the intention of this Article that any successor to the instant contract, whether it be Trinity Services, Inc. or any other contractor shall be in exactly the same position with respect to severance pay liability for any employees that it may elect to terminate for reasons other than permitted by this Article. The incumbent contractor and its successor shall be deemed the same for the purpose of determining severance pay liability and lose [sic] of the contract to a successor shall not be considered a severance. Conversely, refusal to hire by a successor for reasons other than permitted by this Article shall be considered a severance for which the successor shall be liable.
J.A. 40, 70. Even though the severance pay obligation on a successor employer provision was excluded from the wage determination, the Secretary did include a basic seniority concept:
Where eligibility for a fringe benefit listed herein depends upon an employee’s length of service, i. e., severance pay, vacation, etc., credit must be given to an employee’s total length of service defined as the whole span of continuous service with the present (successor) contractor wherever employed, or predecessor contractors) in the performance of similar work at the Federal facility.
J.A. 12, 18. The wage determination did omit some other specific provisions from the collective bargaining agreements.16 One of these provisions would require a contractor to forego hiring new workers until all employees of the incumbent with accrued seniority rights who had been laid off and who qualified to do the available work had been offered reemployment.17
On October 27, 1976, while competitive bidding for a new contract was underway, Trinity filed suit for declaratory and injunctive relief against both the Secretary of Labor, who is responsible for issuing wage determinations under the Act, and the Secretary of the Air Force, who is ultimately responsible for the issuance of service contracts at Air Force facilities.18 The two service employees unions were also originally named as defendants, but on order of the district court were realigned as plaintiffs. Plaintiffs, alleging that the wage determinations issued were inconsistent with the Act of 1965 as amended, sought to prohibit bid openings for the two contracts pending issuance of valid wage determination. The basis for this claim was that the severance pay provision of Art. 26, § 10 of both Agreements and certain seniority provisions were wrongfully excluded from the wage determinations without affording plaintiffs opportunity for a hearing.
The district court, treating the papers filed in connection with plaintiffs’ motion for a preliminary injunction as cross-motions for summary judgment,19 on November 24, 1976 entered an order 20 and memorandum opinion21 enjoining the Secretary of the Air Force from opening bids or awarding new contracts for custodial services at Cape Canaveral or Patrick Air Force Base until valid wage determinations had been issued.22 In so ruling, the district *1256court concluded that the wage determinations issued by the Secretary of Labor did not comply with the Service Contract Act.
The district court found that Art. 26, § 10 was a valid fringe benefit in the collective bargaining agreements and was required to be included in the wage determinations issued by the Secretary of Labor.23 The court acknowledged that the effect of the provisions was to tend to force any successor contractor to retain the predecessor’s employees by requiring the successor to hire them or pay them a severance indemnity.24 Yet the district court found that the severance provision “was bargained for and was not required by statute or regulation” and was “within the expansive conception of ‘fringe benefit’ contained in the Act.”25 The court determined that the inclusion of the severance provision would further the goals of the Act by eliminating the incentive for successor contractors to refuse to hire senior employees of the predecessor. The court observed that a successor gains a competitive bidding advantage over an incumbent, and contrary to the purpose of the Act, can keep the actual wage paid for custodial work artificially depressed.26 The court believed that through the severance provision here, the custodial employees “bargained themselves out of this dilemma.” 27 The court also referred to certain “seniority rights” that were omitted from the determinations, but it did not explain what those were.28
The district court also stated that Congress expected the Secretary of Labor to reject any wage or fringe benefit that was inconsistent with prevailing local standards, and contemplated that such a rejection be made only after a hearing, which was not held in this instance. The court said that before the “severance provision and seniority rights” could be excluded from the wage determination, a hearing must be held and proper findings made in accordance with the statute.29
III. THE HEARING REQUIREMENT
We turn first to the contention that the Secretary should have held a hearing before determining that Art. 26, § 10 was not a valid fringe benefit.
Section 353(c) provides that the successor’s obligations to pay wages and fringe benefits and increases therein shall not apply if the Secretary finds “after a hearing . that such wages and fringe benefits are substantially at variance with those which prevail for services of a character similar in the locality.” When the Secretary did not include Art. 26, § 10 in the wage determinations, he did not hold a hearing. The district court found this to be error.
The purpose of section 353(c)’s variance hearing is to determine the factual question of whether a particular fringe benefit or wage is “substantially at variance” with the wages or benefits that prevail in the locality. Before section 353(c) is relevant in any particular case, it must first be determined that the particular benefit or wage in question is a monetary wage within the meaning of section 351(a)(1) or a fringe benefit within the meaning of section 353(a)(2). That Congress intended the variance hearing to operate in this manner is evident from the Senate Committee report on the 1972 amendments:
[Sjervice employees should be protected against instances where the parties may not negotiate at arms length. For example, a union and an employer may enter into a contract, calling for wages and fringe benefits substantially lower than the rates presently prevailing for similar services in the locality. Likewise, a union and employer may reach an agreement providing for future increases substantially in excess of any justifiable increas*1257es in the industry. Finally, it is possible that over a long period of time, predetermined contractual rates might become substantially at variance with those actually prevailing for services of a character similar in the locality.
The committee concluded that the dual objectives of protecting the service worker and safeguarding other legitimate interests of the federal government could be best achieved by requiring the Secretary to predetermine the wages and fringe benefits contained in the collective agreement, except in the instance where he finds, after notice to interested parties, and a hearing, that the record discloses by a clear showing that such contractual wages and fringe benefits are substantially at variance with those prevailing for services of a character similar in the locality.
S.Rpt.No.1131, 92d Cong., 2d Sess. 4-5 (1972) (emphasis added), U.S.Code Cong. & Admin.News 1972, pp. 3534, 3537.
The Secretary did not exclude Art. 26, § 10 because it was at variance with the wages or benefits that prevailed in the locality; rather, the provision was excluded because it was not a valid fringe benefit within the meaning of section 351(a)(2). This is a threshold question of law. If Art. 26, § 10 — or any excluded seniority provision — is not within one of the categories of fringe benefits listed in section 351(a)(2), the question of the appropriateness of the variance hearing can never arise. Thus, the factual-type hearing contemplated by section 353(c) was not required in this case.
IV. SECTION 351(a)(2) AND THE SUCCESSOR EMPLOYER’S DUTY TO MAKE A SEVERANCE PAYMENT TO THE PREDECESSOR’S EMPLOYEES
Art. 26, § 10, quoted above,30 provides that if a successor employer does not hire the predecessor’s employees, the successor must pay the employees a severance benefit. The district court ruling requiring that Art. 26, § 10 be included in the wage determinations allows an incumbent contractor and its employees, by agreement, to bind a successor contractor to either hiring the predecessor’s employees or paying them a severance benefit even though no formal employment relationship between the successor and the employees comes about. It is our view that Art. 26, § 10 of the collective bargaining agreements between plaintiff-Trinity and plaintiff-unions is not a bona fide fringe benefit within the meaning of the Service Contract Act.
We first consider the language of the statute. Although “fringe benefit” is not specifically defined in the Act, section 351(a)(2), quoted above,31 which requires that certain fringe benefits be included in the wage determinations, contains a list of specific fringe benefits. Severance pay obligations are not specifically listed, but the statute does cover “other bona fide fringe benefits not otherwise required by Federal, State, or local law to be provided by the contractor or subcontractor.” If Art. 26, § 10 is within the scope of section 351(a)(2), it must fall within the category of “other bona fide fringe benefits.”
All of the examples of fringe benefits in section 351(a)(2) require the employer who extends such a benefit to his own employees to incur a present cost or the risk of a future cost. That is, to provide the benefit, the employer must make a payment to the employee (or to a fund maintained in the employee’s behalf) for the present or future use of the employee (or his beneficiary), allow the employee to accrue some form of deferred compensation (such as vacation time), or incur the risk of granting the benefit to the employee (or his beneficiary) at some future time (such as compensation for injuries or illness from occupational activity).32 Many examples of bene*1258fits can be imagined which involve a present cost or the present risk of a future cost to the employer of the workers. These are “bona fide fringe benefits.” 33
Art. 26, § 10 is not a benefit like the ones which section 351(a)(2) specifically covers. The predecessor employer, by the plain terms of Art. 26, § 10, can never be liable for a payment under that provision of the collective bargaining agreement. No deferred compensation is accrued by the employee at the employer’s expense, the employer assumes no risk of ever having to make a payment, and no present payment is made by the employer to the employee or to a fund maintained for the benefit of the employee or his beneficiaries. It is certainly true that Art. 26, § 10 attempts to give the employee a present benefit, for if the successor employer accepts such obligation it provides that employee with a greater amount of employment security: a successor employer is less likely to refuse to hire the predecessor’s employees, and it may be more difficult for a competitor even to succeed to the contract. But the present benefit is unlike all of the benefits listed in section 351(a)(2), in that it does not require an incumbent employer to incur any cost with respect to the putative benefit.
Similarly, Art. 26, § 10 differs from the other benefits listed in section 351(a)(2) in that its value to the recipient is incapable of being ascertained in a definite amount whereas the obligations imposed under section 351(a)(2) can be met by making equivalent payments in cash under regulations promulgated by the Secretary. Assigning an equivalent cash value to Art. 26, § 10 would seemingly be impossible. It has no present actual monetary value, and it is incapable of being actuarialized because it is contingent on contract turnover, which is not capable of prediction in any accurate way. All of the other specific benefits in section 351(a)(2) can be given a value. Hence, Art. 26, § 10 is not the type of benefit which is covered by section 351(a)(2).
Were we to deem Art. 26, § 10 a fringe benefit within the meaning of the Act, we would violate the apparent meaning of section 351(a)(2). It is a well-settled principle of statutory construction that where specific words precede or follow general words in an enumeration describing a particular subject, the general words are construed to embrace only objects similar in nature to those objects enumerated by the specific words. Weyerhauser Steamship Co. v. United States, 372 U.S. 597, 600-01, 83 S.Ct. 926, 10 L.Ed.2d 1 (1963); Fourco Glass Co. v. Transmirra Products Corp., 353 U.S. 222, 228-29, 77 S.Ct. 787, 1 L.Ed.2d 786 (1957); Federal Trade Commission v. Manager, Retail Credit Co., Miami Br. Office, 169 U.S.App.D.C. 271, 276-77, 515 F.2d 988, 993-94 (1975); Wedding v. Wingo, 483 F.2d 1131, 1135 (6th Cir. 1973); 2A Sutherland Statutory Construction, § 47.17, at 103 (4th ed. Sands 1973). If Art. 26, § 10 were considered an “other bona fide fringe benefit,” then the interpretative principle of ejusdem generis would be violated and the statute would be construed contrarily to its apparent meaning.
Our interpretation is bolstered by section 353(c), which states that successor employers shall pay wages and fringe bene*1259fits "“to which such service employees would have been entitled if they were employed under the predecessor contract.” A severance pay obligation which matures only if a successor employer takes over the contract and does not rehire the employee 34 is not a fringe benefit to which employees “would have been entitled if they were employed under the predecessor contract.” By definition, the employees can never be entitled to this benefit under the predecessor contract, because the benefit is paid only if the successor refuses to hire the predecessor’s employees. The Act contemplates that a successor employer provides benefits to its employees that the predecessor provided to the predecessor’s own employees. There is nothing in the statute which requires a successor to extend benefits to the predecessor’s employees absent the formation of an employer-employee relationship between the successor and the predecessor’s employees.35
The fact that the Art. 26, § 10 “benefit” does not impose any cost upon the incumbent employer raises a second consideration which bolsters our conclusion that Art. 26, § 10 falls outside the scheme of the Act. Section 351(a)(2) does cover future benefits, and it is true that Art. 26, § 10’s benefit can only accrue in the future. However, the statute is expressly limited to wage increases or future fringe benefit increases that are a result of “arms-length negotiations.”36 The purpose of this language is clear: it would be a simple matter for an employer who, for example, expects to leave the business at the end of the contract term to promise his employees massive wage increases, full well knowing he will never pay them, in the hope of binding the successor employer for his employees’ benefits.37 The requirement for “arms-length negotiations” is an important ingredient of ensuring that wage rates and fringe benefits are in general accord with those prevailing in the locality.
Art. 26, § 10 contains nothing about which the employer and employee can fruitfully bargain at arm’s length. Trinity would never have to pay anything under the terms of the provision; no burden whatsoever is imposed on Trinity. Indeed, Trinity is benefited by the provision: a competitor bidding for the contract at renewal time would have either to include the costs of making severance payments upon termination of Trinity’s workforce in its bid or to base its bid on Trinity’s present wage costs if that workforce would be hired. If a competitor intended to hire a less-experienced workforce and thereby reduce wage costs, it would have to make the Art. 26, § 10 payment. This would bring the competitor’s projected costs into rough parity with Trinity’s. This would work to Trinity’s benefit, as its competitive position would be enhanced and it would be better *1260able to retain the contract. As for the unions, Art. 26, § 10 would work to the employees’ benefit if its terms were imposed on the successor employer. The agreement of Trinity and its employees’ unions to require a successor employer to pay a severance benefit to the employees if the successor did not hire them is a classical example of a mutually beneficial arrangement. This is not the type of arrangement that the Service Contract Act as presently written is designed to protect.
[ID Our reading of the Act is also supported by the legislative history. The 1965 House and Senate Committee Reports on the Act clearly demonstrate that the principal purpose of the Act was establishing minimum wage and fringe benefit standards to be provided by the successor employer. The House Report stated:
This bill is proposed to provide much needed labor standards protection for employees of contractors and subcontractors furnishing services to or performing maintenance service for Federal agencies.
H.R.Rpt.No.948, 89th Cong., 1st Sess. 1 (1965). Accord, S.Rept.No.798, 89th Cong., 1st Sess. 1 (1965), U.S.Code Cong. & Admin. News 1965, p. 3737. Nothing in the House or Senate Report suggests that a successor should be required to hire the predecessor’s employees, or that a successor should be required to make a payment to the predecessor’s employees if the successor did not hire them.
Other language in the reports suggests that the concern of the Congress was upholding minimum standards. The House Report stated:
Concern over protection for wage standards of employees of employers having service contracts with the Federal Government has been expressed by Members of Congress for a number of years.
H.R.Rpt.No.948, supra, at 2. Both reports stated:
Since labor costs are the predominant factor in most service contracts, the odds on making a successful low bid for a contract are heavily stacked in favor of the contractor paying the lowest wages. Contractors who wish to maintain an enlightened wage policy may'find it almost impossible to compete for Government service contracts with those who pay wages to their employees at or below the subsistence level. When a Government contract is awarded to a service contractor with low wage standards, the Government is in effect subsidizing subminimum wages.
H.R.Rpt.No.948, supra, at 2-3; S.Rpt.No. 798, supra, at 3-4, U.S.Code Cong. & Admin.News 1965, p. 3739. Both 1965 reports on the Act demonstrate that Congress was concerned with maintaining wage and fringe benefit levels to be provided by the successor employer. This comports with the plain language of the statute. Nothing suggests that Congress intended the plain language to go farther and ensure job continuity.
Section 353(c) of the Act, which requires a successor employer to pay the wages and fringe benefits included in the wage determination, was added in 1972.38 In discussing this section, both the House and Senate Reports state:
[Successor] [contractors or subcontractors . . . must pay service employees at least the wages and fringe benefits (including accrued wages and fringe benefits) to which the service employees would have been entitled had they been employed under the predecessor contract, as well as any prospective wage and fringe benefit increases provided for in a collective bargaining agreement to which they would have been entitled had they been so employed, if the Secretary elects, and if such prospective increases were the result of arm’s-length negotiations.
H.R.Rpt.No.92-1251, 92d Cong., 2d Sess. 5 (1972); S.Rpt.No.1131, supra, at 3 U.S.Code Cong. & Admin.News 1965, p. 3536. The Reports anticipate that employees under the successor contracts receive the same benefits they would have received if their employment under the predecessor contract *1261had continued. And if the employee was entitled to a benefit upon the termination by the predecessor of the employee-employer relationship during the contract term, the employee would also be entitled under the successor’s contract to the same benefit upon termination by the successor during the contract term of the employee-employer relationship. Nothing in the history of the 1972 amendments suggests that these changes in the Act sought to fill the “gap” that exists when an incumbent loses the contract and the successor does not hire the predecessor’s employees.39
The district court noted that excluding Art. 26, § 10 from the wage determination would allow competitors at the time of the contract’s renewal to underbid the incumbent by hiring less experienced and therefore cheaper employees to do the same work. Imposing the severance payment obligation on the successor if the predecessor’s work force was not hired would “equalize” the bidding process, in that the competitor placing the bid would have to include as a cost the amounts to be paid to employees of the predecessor not hired. The effective end result of this “equalization” would be to increase job security; even if the incumbent was replaced, an incentive would exist to hire the predecessor’s employees.40
The district courts analysis is cogent: the Act is designed to protect service employees by preserving the benefits gained under prior employers. It is ironic and unfortunate that the employees may lose their jobs when the incumbent contractor is replaced. The Act preserves many job-related benefits but this may be for naught if the employees cannot keep their jobs. But whatever policy considerations may commend the district court’s ruling, we cannot alter the plain language of the Act which does not cover this type of severance-pay benefit in the wages and benefits when the obligation is one that must be paid by the successor employer and he has not agreed thereto. Indeed, it may be that Congress chose to recognize the employer’s interest in choosing his own work force. Howard Johnson, supra, 417 U.S. at 261, 94 S.Ct. 2236; Burns, supra, 406 U.S. at 280 n.5, 92 S.Ct. 1571. If Congress intended that the Act enhance employment security, it would have been a simple enough matter to write the statute accordingly.41 While the disadvantages of not including a severance-pay benefit such as Art. 26, § 10, as discussed by the district court, may be prominent, we find no indication in the plain language of the statute or the legislative history that Congress intended the Act to reach that far.
*1262V. OTHER SENIORITY RIGHTS
The district court held that the Secretary erred in not including certain “seniority rights” in the wage determination, but the court did not specifically state what these rights were. Memorandum Opinion, at J.A. 102, 103, 104. We assume that the court was referring to certain provisions in articles of the collective bargaining agreement entitled “Seniority and Transfers.”42
The wage determinations issued by the Secretary of Labor did contain a basic seniority concept:
Where eligibility for a fringe benefit listed herein depends upon an employee’s length of service, i. e., Severance pay, vacation, etc., credit must be given to an employee’s total length of service defined as the whole span of continuous service with the present (successor) contractor wherever employed, or predecessor contractors) in the performance of similar work at the Federal facility.
J.A. 12, 18. From this language, it is clear that the successor employer must give an employee it hires credit for similar work performed at the federal facility. The successor employer must provide workers with an equal amount of seniority the same wages and fringe benefits they would have received under the predecessor contract. Thus, seniority must be recognized by the successor in compensating the employees and providing them with other benefits.
We do not believe that the Act requires more than this. Seniority is not a form of compensation that the employer can pay. It is not specifically listed as a section 351(a)(2) fringe benefit, and it is not in the same class as the other benefits listed there. Seniority is but a means of determining how wages and fringe benefits are to be allocated. See Franks v. Bowman Transportation Co., 424 U.S. 747, 766, 96 S.Ct. 1251, 47 L.Ed.2d 444 (1976); Davis v. Alabama Power Co., 383 F.Supp. 880, 888 (N.D.Ala.1974), aff’d per curiam, 542 F.2d 650 (5th Cir. 1976), aff’d, 431 U.S. 581, 97 S.Ct. 2002, 52 L.Ed.2d 595 (1977). For the reasons given earlier with respect to Art. 26, § 10, seniority is not a “fringe benefit” within the meaning of section 351(a)(2). Instead, seniority is a means for determining the entitlement to a fringe benefit, and this was recognized in the wage determinations.
For these reasons, we disagree with the district court’s apparent conclusion that the wage determinations should have gone farther.
VI. CONCLUSION
It is true that certain kinds of obligations of predecessor employers toward their employees may be imposed on successor employers as a matter of federal labor law in certain circumstances. See Howard Johnson Co. v. Detroit Local Joint Exec. Bd., 417 U.S. 249, 94 S.Ct. 2236, 41 L.Ed.2d 46 (1974); NLRB v. Burns Int. Security-Service, Inc., 406 U.S. 272, 92 S.Ct. 1571, 32 L.Ed.2d 61 (1972); John Wiley & Sons, Inc. v. Livingston, 376 U.S. 543, 84 S.Ct. 909, 11 L.Ed.2d 898 (1964). But here the question is to what extent the Service Contract Act imposes an obligation on a successor to adhere to a provision in a collective bargaining agreement that requires the successor to make a payment to the predecessor’s employees if that workforce is not hired by the successor. The federal government will not contract with successors who do not meet certain wage and fringe benefit standards contained in prior collective bargaining agreements. The obligations imposed by Art. 26, § 10 are not among those which Congress has insisted that a successor meet. Hence, the Secretary of Labor did not violate the Act when he excluded that provision as well as other seniority rights provisions from the wage determinations. The judgment of the district court is therefore reversed, and the case is remanded for proceedings consistent with this opinion.
Judgment accordingly.

. The statute also contemplates that many employers have insurance against such risks; such insurance coverage, a present cost, is also *1258a fringe benefit within the meaning of section 351(a)(2).
. The parties, in attempting to discern what types of benefits are bona fide fringe benefits within the meaning of section 351(a)(2), dispute whether the test should be “benefit received” or “cost incurred.” Plaintiffs urge us to determine whether the employees “received a benefit”; by this test, Art. 26, § 10 would be a fringe benefit, for the employees do receive a benefit if the successor assumes the liability. However, this reading would embrace many types of benefits not a product of arms length negotiations, see text at 1259-1260. Given the policy of the Act to maintain wage and fringe benefit standards that are negotiated at arms length and which do not exceed prevailing standards in the same locality, we think a better standard is whether the employer “incurred a cost.” Plaintiffs fail to recognize, however, that a funeral or sick leave provision subjects the employer to a present risk of a cost, as that cost might be incurred at any time. All of the examples in section 351(a)(2) meet the cost incurred test, and we can think of no bona fide fringe benefits which do not.
. It is important to distinguish Art. 26, § 10 from a “pure” severance payment obligation. A predecessor employer might incur an obligation to make payments to its employees when it lays them off. This is payment made at the predecessor’s expense. This is a benefit similar to those specifically listed in section 351(a)(2), and is the proper subject of a wage determination. In this case, the severance payment obligation Trinity had toward its own employees was included in the wage determination. See J.A. 9-10, 16-17. Thus, the successor employer to Trinity’s contract must make severance payments to its employees should it lay them off. Art. 26, § 10, which requires the successor to make a severance payment should it decline to hire the predecessor’s workforce, is completely different from a severance payment obligation an employer has with respect to its own employees.

. See Kentron Hawaii, Ltd. v. Warner, 156 U.S.App.D.C. 274, 480 F.2d 1166 (1973), where Judge Wilkey wrote:
Enclave wage determinations afford the incumbent contractor an opportunity for “last minute artificial inflating of rates in anticipation of the contract renewal,” thereby dampening competition from other possible offerers.
At 287-288, 480 F.2d at 1179-80. While the variance hearing procedure might eventually detect the non-arm’s length collective bargaining agreement provision, the inclusion of the statutory language on arm’s length negotiation makes Congress’ intent clear — only bona fide wages and fringe benefits are within the scope of sections 351(a)(1) and 353(c).

. A corollary of this conclusion is that the Act does not require a successor to hire the predecessor’s work force. Service Employees’ International Union v. General Services Administration, 443 F.Supp. 575 (E.D.Pa.1977). The quoted portions of House Report No. 92-1251 and Senate Report No. 1131 which appear in the text supra clearly show that Congress contemplated that a successor contractor might not employ the predecessor’s work force. In floor debate, Congressman Ben B. Blackburn stated in opposition to the bill that the obligations imposed by section 353(c) apply “even if the successor contractor employs his own work force and does not retain any of the predecessor contractor’s employees.” 188 Cong.Rec. 27139 (1972). See Subcommittee on Labor-Management Relations of House Committee on Education and Labor, Congressional Oversight Hearings: The Plight of the Service Worker Revisited 8-9 (April, 1975); Problems of Service Contract Act and Protection of Florida Cape Area Workers: Hearings before the Federal Spending Practices, Efficiency, and Open Government Subcommittee of the Senate Committee on Government Operations, 94th Cong., 2d Sess. 3 (1976) (statement of Kenneth L. Woodfin, Assistant Administrator for Procurement, National Aeronautics and Space Administration).

. In our opinion, it seems clear that the unions, by Art. 26, § 10, are attempting to create an employment relationship between its employees and the successor. The Act does not require that this relationship be preserved. See note 39 supra. This, however, is not the specific question presented to the court. We are asked to decide whether certain collective bargaining agreement provisions are “fringe benefits” within the meaning of the Act. It is difficult, however, to view these questions separately: if the Act provided for continuity of employment, this case would not have been presented to us.
