OPINION OF THE COURT
After consideration of oral argument and briefs, the opinion of the Court of Appeals by Judge Wilhoit, as set forth below, is hereby adopted as the opinion of this court.
“John D. White was awarded workers’ compensation benefits for total permanent disability arising from a work-related injury occurring on July 11, 1978. The Workers’ Compensation Board calculated the amount of this award utilizing the methodology approved by the Supreme Court in Transport Motor Express, Inc. v. Finn, Ky., 574 S.W.2d 277 (1978). On review, the Pike Circuit Court set aside the Board’s calculation and directed it to enter an order which increased the claimant’s weekly benefits, basing its judgment on two 1978 amendments to the Workers’ Compensation Act. From this judgment, the Special Fund and the claimant’s employer appeal.
The Board found that White’s average weekly wage was $338.80, which under Finn, supra, it reduced to $112.00 (the applicable statutory maximum under KRS 342.-740) before apportioning forty percent against the employer as resulting from the injury itself and forty percent against the Special Fund as resulting from arousal of a dormant, nondisabling condition; the remaining twenty percent was found to be noncompensable as prior active disability. Under the Board’s order, the Special Fund and the employer were each required to pay White $44.80 weekly.
The circuit court, relying on the 1978 amendments to KRS 342.120(5) and KRS 342.620(20), directed the Board to award the claimant $112.00 weekly, to be paid in equal halves of $56.00 each by the Fund and the employer. The court reached this result by concluding that the claimant’s weekly benefits would be 66⅜% of his average weekly wage of $338.80 times 80% (the percentage of disability caused by the injury), i.e., $180.70 weekly. Since this amount exceeded the statutory maximum, the court reduced it to $112.00 before dividing it pro*78portionately between the Fund and the employer.
KRS 342.120(5) (1978)1 provided:
‘If it is found that the employe is a person mentioned in paragraphs (a) or (b) of subsection (1) of this section, and a subsequent compensable injury or occupational disease has resulted in additional permanent disability, so that the degree of disability caused by the combined disabilities is greater than that which would have resulted from the subsequent injury or occupational disease alone, and the employe is entitled to receive compensation on the basis of the combined disabilities, and when applying the formula for income benefits to the employer’s and special fund’s percentage of disability, and the income benefits exceed the limitation contained in KRS 342.740, then in that event the special fund’s and employer’s liability shall be reduced proportionately to the point where the shares of each, when combined, do not exceed the limitation established by KRS 342.740.’
KRS 342.620(20) (1978)2 provided, in relevant part:
‘Except as otherwise provided in KRS 342.750, the formula for income benefits shall be sixty-six and two-thirds percent (66⅜%) of the average weekly wages of the employe at the time of his injury, multiplied by the percentage of disability caused by injury or occupational disease, subject to the limitation contained in KRS 342.740.’
KRS 342.750, dealing with income benefits for death, has no application here.
The appellants argue that, notwithstanding these provisions, the Finn methodology continued to be governing because doing otherwise would render ineffective the exclusion for prior active disability contained in KRS 342.120(4). They maintain that KRS 342.620(20) (1978) has no application to prior active disability and that KRS 342.-120(4), which does, should prevail over it.
We cannot agree with this argument. The statutory provisions set out above were not in effect at the time of the injury in Finn. There the Court noted that ‘[t]he apportionment function [under KRS 342.-120] is separate and distinct from the function provided for in KRS 342.730[,]’ and that ‘[n]o other section ... has as its objective the computation of an actual dollar amount — that statement applies with particular force to KRS 342.120.’ 574 S.W.2d at 280. The enactment of KRS 342.120(5) (1978) changed this. It is manifest that this subsection, when taken with KRS 342.-620(20) (1978), established the method of computation for subsequent injury claims; the circuit court correctly applied the law and properly reversed the Board’s order.
In Finn, the Supreme Court had to interpret the then-existing statutes to give meaning to the exclusion for prior active disability contained in KRS 342.120(4); in the absence of clear statutory direction, it felt that it %a[d] no choice but to give effect to this exclusion[,]’ at 574 S.W.2d at 282, by applying the percentage of noncom-pensable, prior active disability to the claimant’s average weekly wage after reduction under KRS 342.740. By mandating that a claimant’s compensable weekly earnings (66⅜% of his average weekly wage) be multiplied by the percentage of disability caused by the injury or occupational disease, the Legislature clearly indicated an intention to exclude the noncompensable percentage at this level before application of the KRS 342.740 ceiling. The definition subsection applies, by its terms, to all calculations except those for death benefits. We find it significant that KRS 342.120(5) (1978) includes no provision for proportionately reducing a noncompensable share of a claimant’s income benefits due to prior active disability in order for an award not to exceed the statutory maximum when it mandates such proportionate reduction for the shares of the Special Fund and the *79employer. This can only be because the noncompensable portion of a claimant’s income benefits has already been excluded by the formula for income benefits referred to within KRS 342.120(5) (1978) and defined in KRS 342.620(20) (1978).
The appellants would have us disregard the 1978 amendments and retain the Finn methodology. Such a course would be contrary to well-established principles of statutory construction. ‘All statutes are presumed to be enacted for the furtherance of a purpose on the part of the legislature and should be construed so as to accomplish that end rather than to render them nugatory.’ Commonwealth ex rel Martin v. Tom Moore Distillery Co., 287 Ky. 125, 152 S.W.2d 962, 967 (1941). The rule that a specific statute controls a more general one is firmly established in the law of the Commonwealth. Heady v. Commonwealth, Ky., 597 S.W.2d 613 (1980); Gish v. Shaver, 140 Ky. 647,131 S.W. 515 (1910). KRS 342.120(5) (1978) specifically set forth the manner by which the claimant’s award was to be calculated.
We are not unaware that our holding adopts the same concept of exclusion that the Supreme Court rejected in Finn, supra. However, given the plain language of the statutory amendments of 1978 which were not in effect at the time of the injury in Finn, we believe this course has been mandated by the Legislature. Of course, because these statutes have been repealed, their application, as well as that of this opinion, is restricted to injuries occurring while they were in force.”
The opinion of the Court of Appeals is hereby affirmed.
