OPINION BY
Denise Kramer (Claimant) petitions for review of a June 26, 2001 order of the Workers’ Compensation Appeal Board (WCAB) affirming the decision of a workers’ compensation judge (WCJ) to deny Claimant’s Petition to Review Compensation Benefit Offset (Offset Review Petition). The WCJ had determined that Rite Aid Corporation (Employer) was entitled, under section 204(a) of the Workers’ Compensation Act (Act),1 to take a credit for severance benefits paid to Claimant. We reverse.
Claimant sustained a work-related injury on February 20, 1998, while working at Employer’s Shiremanstown, Pennsylvania facility. As a result, Claimant received temporary total disability benefits in the amount of $864.86 per week through June 28, 1998, when Claimant returned to work with injury-related restrictions. On March 12, 1999, Employer relocated its Shire-manstown facility to Maryland, and, as a consequence, Employer laid off the employees, including Claimant, who worked at that facility. Following the lay-off, Employer reinstated Claimant’s workers’ compensation benefits.
Subsequently, Claimant received a check from Employer in the amount of $8,855.02, representing the net amount of “severance” pay due Claimant as a result of Employer’s relocation. The payment was part of a “Severance Agreement” contained in a January 7, 1998 Addendum to the most recent collective bargaining agreement (CBA) between Employer and Teamsters, Local 776, the union for Employer’s employees (Union).2
On May 14, 1999, Employer sent Claimant a Notice of Compensation Benefits Off*955set (Offset Notice), informing her that Employer, as authorized by section 204(a) of the Act, 77 P.S. § 71(a), intended to use the $3,335.02 severance as a credit against Claimant’s workers’ compensation benefit». (R.R. at 50a-51a.) As a result of the offset, Claimant did not receive any workers’ compensation benefits from June 5, 1999 until August 10, 1999,3 when total disability benefits once again were reinstated. (WCJ’s Findings of Fact, Nos. 9-10.)
On May 20, 1999, Claimant filed an Offset Review Petition alleging that Employer’s offset was unconstitutional and contrary to the Act. (R.R. at la-2a.) Employer filed an answer denying Claimants allegations, and, following a hearing, the WCJ issued a decision denying Claimant’s Offset Review Petition. The WCJ held that the $3,355.02 received by Claimant under the CBA was, in fact, a severance benefit as defined in 34 Pa. Code § 123.2 4 and that Employer properly took an offset pursuant to section 204(a) of the Act. (R.R. at 10a-12a.) The WCJ also concluded that he lacked jurisdiction over Claimant’s constitutional challenge to the Act’s severance benefit offset provision in section 204(a). (WCJ’s Findings of Fact, No. 2; WCJ’s Conclusion of Law, No. 3; R.R. at 9a, 12a.) Following Claimant’s appeal, the WCAB affirmed. Rejecting Claimant’s reliance on pre-Act 57 precedent to support a contrary result,5 the WCAB agreed that Employer was entitled to a credit for the $3,335.02 paid to Claimant. The WCAB then concluded that it, too, lacked authority to pass upon the constitutionality of the Act’s provisions. (R.R. at 18a-22a.)
*956Claimant now petitions this court for review,6 arguing that the WCJ and WCAB erred in denying Claimant’s Offset Review Petition. First, Claimant asserts that Employer was not entitled to a credit for the $3,335.02 payment because this payment did not fall within the definition of “severance” contained in the regulations. Alternatively, Claimant contends that, even if the payment is deemed to be severance, it is not subject to offset under section 204(a) of the Act. Claimant also renews her argument that section 204(a) of the Act, as amended in 1996 to provide for the offset of severance pay against workers’ compensation benefits, is unconstitutional as violative of the Equal Protection Clauses of the U.S. and Pennsylvania Constitutions.7
The regulations interpreting section 204(a) define “severance benefit” as:
A benefit which is taxable to the employe and paid as a result of the employe’s separation from employment by the employer liable for the payment of workers’ compensation, including benefits in the form of tangible property. The term does not include payments received by the employe based on unused vacation or sick leave or otherwise earned income.
34 Pa.Code § 123.2 (emphases added). Claimant first argues that, although labeled “severance” by Employer, the $3,335.02 payment she received actually falls under the exclusion of “otherwise earned income.” We disagree.
In this case, Claimant received her “severance” payment pursuant to paragraph 1 of Addendum C of the CBA, which, under the heading “Severance Agreement,” provides in pertinent part:
Conditional upon the employees continued efforts per the terms of the [CBA], and the signing of a release agreed to by the parties, all employees .. .who are laid off voluntarily or involuntarily due to the closure of the Shiremanstown facilities, shall be provided the following severance benefits:
1. Payment for years of service according to the following schedule:
5 to 10 years service — $550.00 per year8 ....
(R.R. at 54a; 107a.)
In her brief, Claimant makes several attempts to characterize the $3,335.02 as *957something other than a “severance” benefit. Claimant contends that Employer did not make the payment based simply on Claimant’s individual severance of her employment relationship with Employer. According to Claimant, the payment actually represents reimbursement of benefits accrued or earned during the employee’s past years of service,9 paid out at the time of departure. Moreover, Claimant maintains that the provisions of the CBA authorizing the payment of these monies was a contractual buyout, made in exchange for the employees’ permission for Employer to relocate. In this regard, Claimant asserts that Addendum C was added to the CBA pursuant to an agreement between Employer and the Union because Employer contemplated closing the Shiremanstown facility and wanted provisions in the newly negotiated CBA granting it permission to do so. Thus, Claimant maintains that, while the terms allowing the closure were under the title “Severance Agreement,” Addendum C would more appropriately be titled “Relocation Agreement,” providing affected employees with past accrued benefits in consideration for employees waiving various legal rights. We are unpersuaded by this argument.
Initially, we note that much of Claimant’s argument is premised on “facts” which are not of record. The “Severance Agreement” negotiated by the Union provides only that Employer’s Shiremanstown facility will be closed and that the employees affected by that closure will receive severance benefits. Nothing in the “Severance Agreement” itself limits Employer’s ability to apply a severance pay credit under section 204(a) of the Act.10 Because the record contains no evidence to establish that the payment in question is not severance as defined in the regulations,11 Claimant’s first argument must fail.
*958Claimant next maintains that, even if the WCJ correctly determined that the $3,355.02 payment received by Claimant under the CBA was a severance benefit as defined in 34 Pa.Code § 123.2, Employer here was not entitled to an offset for such severance under section 204(a) of the Act. The set-off provisions of the Act, set forth in section 204(a), provide in pertinent part:
The severance benefits paid by the employer directly liable for the payment of compensation and the benefits from a pension plan to the extent funded by the employer directly liable for the payment of compensation which are received by an employe shall also be credited against the amount of the award made under sections 108 and 306, except for benefits payable under section 306(c).
77 P.S. § 71(a) (emphases added). Thus, an injured employee who subsequently receives severance benefits paid by an employer directly liable for the payment of compensation, in effect, forfeits workers’ compensation disability benefits in an amount corresponding to those severance benefits.
Claimant first notes that section 204(a) of the Act permits employers to credit such payments against workers’ compensation only to the extent that severance benefits are “paid by the employer ” itself. See Dietrich Industries, Inc. v. Workers’ Compensation Appeal Board (Shank), 725 A.2d 252 (Pa.Cmwlth.1999). Claimant then asserts that Employer here is precluded from taking a credit against Claimant’s total disability benefits because Employer presented no testimony or evidence as to the funding source of the monies paid Claimant. We must disagree. In fact, the record here clearly indicates that it was Employer that gave Claimant the severance check for $3,335.02, (R.R. at 52a), and there is no evidence that the money was funded from any other source.
Nevertheless, Claimant contends that Employer here is not entitled to a statutory credit even if it did fund payment of the severance benefit because Employer was not “directly liable for the payment ” of Claimant’s workers’ compensation, as required under section 204(a) of the Act; rather, Employer’s insurance carrier, the Traveler’s Casualty Company, was the party directly hable for such payments. {See WCJ’s Findings of Fact, No. 9; R.R. at 50a.) Claimant asserts that, if Employer made the severance payments, it clearly does not follow that insurer should reap the benefit by taking a credit for those payments. In effect, Claimant maintains that section 204(a) provides the severance credit only to self-insured employers. On this point, we agree with Claimant.
Statutory construction does not permit courts to ignore the plain and unambiguous language of a statute. See section 1921(b) of the Statutory Construction Act of 1972, 1 Pa.C.S. § 1921(b) (stating that “[wjhen the words of a statute are clear and free from all ambiguity, the letter of it is not to be disregarded under the pretext of pursuing its spirit.”); Latella v. Unemployment Compensation Board of Review, 74 Pa.Cmwlth. 14, 459 A.2d 464 (1983). The plain language of section 204(a) provides that “[tjhe severance benefits paid by the employer directly liable for the payment of compensation ... .which are received by an employe shall also be credited against the amount of the award made .... ” We perceive no ambiguity in *959this language. To the contrary, we conclude that the statute at hand clearly identifies the entity entitled to benefit from the severance credit provided in this section; specifically, the offset is afforded to the employer, not the insurer, only if the employer is directly hable to a claimant for compensation.
The Act does not use the terms “employer” and “insurer” interchangeably. Rather, the Act distinguishes between the two by providing separate and distinct definitions of “employer” and “insurer” in sections 103 and 109 of the Act, respectively, 77 P.S. §§ 21 and 29.
The term “employer,” as used in this [A]ct, is declared to be synonymous with master, and to include natural persons, partnerships, joint-stock companies, corporations for profit, corporations not-for-profit, municipal corporations, the Commonwealth, and all governmental agencies created by it.
77 P.S. § 21.12
“Insurer” means an entity subject to the act of May 17, 1921 (P.L. 682, No. 284), known as “The Insurance Company Law of 1921,”13 including the State Workmen’s Insurance Fund, with which an employer has insured liability under this act pursuant to section 305 or a self-insured employer or fund exempted by the Department of Labor and Industry pursuant to section 305.14
77 P.S. § 29.
Employer here entered into a contract with Traveler’s Casualty Company, a earner for workers’ compensation insurance. Pursuant to that contract, Employer paid premiums to the insurance carrier which, in turn, assumed direct liability to the injured employee for the payment of workers’ compensation benefits. See section 651 of The Insurance Company Law of 1921, 40 P.S. § 811 (stating that every policy of insurance against liability under the Workers’ Compensation Act shall be construed to be a direct promise to the injured employee having a claim under such Act).
Because Employer is not directly liable for the payment of compensation to Claimant and because the entity that is directly liable for such compensation is not Employer, there is no entitlement to a credit pursuant to section 204(a).15
*961Accordingly, we reverse.16
ORDER
AND NOW, this 22nd day of February, 2002, the order of the Workers’ Compensation Appeal Board, dated June 26, 2001, is hereby reversed.
