We address in this case questions of law reported on stipulated facts from the Workers’ Compensation Commission. See 39 M.R.S.A. § 103-D (1989); M.R.Civ.P. 72(a).
Mark A. Tompkins, while employed by Wade & Searway Construction Corporation, injured his left knee in 1987 and his right knee in 1989. United States Fidelity & Guaranty Company (USF & G) was Wade & Searway’s insurance carrier at the time of the first injury and Hanover Insurance Company provided insurance coverage at the time of the second. As a result of those injuries and pursuant to memoranda of payment issued by the compensation insurance carriers, Tompkins received compensation benefits based on his average “wages, earnings or salary.” 39 M.R.S.A. § 2(2)(A) (1989) (hereinafter “wages”). USF & G does not pay benefits directly to Tompkins but, through an agreement with *876 Hanover, reimburses Hanover for its share of the compensation benefits Hanover pays to Tompkins.
Tompkins is a member of the United Brotherhood of Carpenters and Joiners of America, Local 621. At the time of the injuries a collective bargaining agreement existed between Wade & Searway and Local 621 requiring the employer to pay a specific dollar amount per unit of employee-time worked to fund various union-established employee fringe benefits. Hanover included the union payments when calculating the compensation benefits it paid to Tompkins. USF & G, however, refused to include the union payments when determining the amount it reimbursed Hanover for USF & G’s share of the benefits paid.
In
Ashby v. Rust Engineering Co.,
On August 21,1991, following enactment of P.L.1991, ch. 615, but before its effective date, Tompkins filed petitions with the Workers’ Compensation Commission seeking a decision that his average weekly wages included the union payments. Wade & Searway countered by filing a petition to reduce his average wages to an amount that excluded the union payments. The Commission, however, was unable to issue a decision before October 17, 1991, the act’s effective date, and by agreement of all parties reported the case to the Law Court.
I.
By stipulation the parties agree that the payments at issue in the instant case are the same as those we considered in Ashby. Thus, under that decision, an employer would be required to include the union payments in an employee’s average wages. P.L.1991, ch. 615, by its terms, however, does not apply to “those employees awarded compensation consistent with the holding in Ashby.” We must determine, therefore, as an initial proposition, whether Tompkins has been “awarded” benefits within the meaning of this exception.
Tompkins argues that his compensation benefits paid pursuant to the memo-randa of payments issued by the two insurance carriers constitute an “award” within the scope of this exception. Underlying that argument is the implicit contention that voluntary payments made pursuant to a memorandum of payment should be treated the same as a compensation agreement reached by the parties. It is clear, however, that a memorandum of payment is a “compensation payment scheme” distinct from a compensation agreement approved by the Commission under the Workers’ Compensation Act.
See
39 M.R.S.A. §§ 2(3-A), 51-B(5), 51-B(7). A memorandum of payment is merely evidence of prepayment of benefits to an injured employee claiming compensation, and payments are made regardless of the employer’s intention to controvert the claim.
See
39 M.R.S.A. §§ 51-B(5), 51-B(7). Receipt of such payments does not constitute an acceptance by the employee of the nature and scope of an employer’s liability or of the amount or duration of the compensation.
See
39 M.R.S.A. § 51-B(8). In contrast,
*877
section 51-B(8) specifically distinguishes payments made by decision or agreement. Moreover, a compensation agreement is in the nature of a settlement,
see
39 M.R.S.A. § 106(2), and, when approved by the Commission pursuant to 39 M.R.S.A. § 94, is binding on the parties, conclusively establishing “the extent of the employee’s incapacity and the compensability of his injury.”
Hafford v. Kelly,
Thus, although an approved compensation agreement amounts to an “award” of benefits under the act, we conclude that a memorandum of payment, without more, does not constitute an award of benefits within the meaning of the exception to the retroactivity provision of P.L.1991, ch. 615.
II.
Tompkins nonetheless argues that application of the retroactivity provision to injuries occurring before October 17, 1991, violates both the due process clause and the equal protection clause of the Fourteenth Amendment. The Supreme Court has consistently and repeatedly stated that the retroactive aspects of economic legislation meet the requirements of the due process clause if enacted to further a legitimate legislative purpose by rational means.
See, e.g., General Motors Corp. v. Romein,
— U.S. -, -,
In
General Motors Corp. v. Romein,
the Supreme Court rejected a due process argument on facts procedurally similar to the instant case. In 1985 the Michigan Supreme Court had construed a workers’ compensation statute as allowing employers to reduce certain compensation benefits. In 1987 the Michigan Legislature rejected the court’s construction of the law, enacted legislation overturning the court’s decision, and required employers to refund $25 million in benefits that had been validly withheld under the earlier law. Under the test set out above, the
Romein
Court held that the 1987 statute’s retroactive provision did not violate the due process clause because 1) the statute furthered the legitimate legislative purpose of correcting the Michigan Supreme Court’s unexpected construction of the 1980 law, and 2) the statute did so by rational means, i.e., by preserving the “delicate legislative compromise” of the earlier law and by equalizing payments made by employers who had withheld and those made by employers who had not.
Romein,
— U.S. at -,
The instant case, like
Romein,
involves a legislative attempt to correct what the Legislature viewed as an improper expansion of Maine’s workers’ compensation laws governing the “average weekly wage of an individual.” Legis.Rec. 1523 (1st Spec.Sess.1991) (statement of Rep. Hastings). In addition, P.L.1991, ch. 615, evidences the Legislature’s attempt to restore the Workers’ Compensation Act to its pre-
Ashby
status and the “delicate legislative compromise” contained therein. We thus
*878
conclude that this curative legislation does not violate the requirements of the due process clause.

2 Rotunda, Nowak & Young,
Constitutional Law,
§ 15.9, at 108 (1986 & Supp.1991);
Sabasteanski v. Pagurko,
Tompkins argues, notwithstanding
Romein,
that P.L.1991, ch. 615, unconstitutionally impairs his “vested” right to workers’ compensation benefits.
See Merrill v. Eastland Woolen Mills, Inc.,
This notion of a vested right to a certain level of benefits, however, is necessarily reliant on viewing the workers’ compensation laws as contractual in nature, a view we have long since rejected.
See Norton v. C.P. Blouin, Inc.,
III.
Tompkins next argues that, even assuming the retroactivity provision does not violate the proscriptions of the due process clause, the provision’s application to his petition pending before the Commission violates the Fourteenth Amendment’s equal protection clause.
See Logan v. Zimmerman Brush Co.,
*879
Section 302 states in pertinent part that “[ajctions and proceedings pending at the time of the passage, amendment or repeal of an Act or ordinance are not affected thereby.” In
City of Portland v. Fisherman’s Wharf Associates II,
Because proceedings pending on the effective date of the Act are not subject to section A-20, the statute avoids the dilemma of those petitioners such as Tompkins who are “caught in the switches.”
See Schlear v. Fiber Materials, Inc.,
The entry is:
Remanded to the Workers’ Compensation Commission for further proceedings consistent with the opinion herein.
All concurring.
Notes
. Subsection G provides that: " 'Average weekly wages, earnings or salary’ [defined in section 2(2)(A) ] does not include fringe benefits, including but not limited to employer payments for or contributions to a retirement, pension, health and welfare, life insurance, training, social security or other employee or dependent benefit plan for the employee’s or dependent’s benefit or any other employee's dependent entitlement.”
. Analysis under the due process clause of the Maine Constitution, Me. Const, art. I, § 6-A, yields no different result in this case. The due process analysis applied in Romein is substantially similar to the three-part test governing analysis under the Maine Constitution:
1. The object of the exercise must be to provide for the public welfare.
2. The legislative means employed must be appropriate to the achievement of the ends sought.
3. The manner of exercising the power must not be unduly arbitrary or capricious.
