JUSTICE WHITE delivered the opinion of the court:

Aetna Casualty Surety Company of Illinois (Aetna), the worker's compensation insurance carrier for Kenneth Brock's employer, appeals from an order of the circuit court of Cook County distributing the proceeds from the settlement of a lawsuit and temporarily suspending future workers' compensation payments by Aetna to the conservator of Brock's estate. The issues presented are: whether the circuit court properly determined the amount of credit against payment of future workers' compensation benefits to which Aetna is entitled; whether the conservator's attorney fees were properly assessed against this credit; and whether litigation costs assessed against Aetna should have been charged against the credit.

The relevant facts are largely undisputed. Kenneth Brock suffered severe injuries while in the course of his employment with Park-Ohio Industries, Inc., a division of Bennett Industries, Inc., and he was treated for these injuries by certain physicians at Riverside Hospital in Kankakee, Illinois. Subsequently, plaintiff, Cora Lee Lewis, conservator of the estate of Kenneth Brock, brought an action sounding in professional medical negligence and strict liability against the treating physicians, Riverside Hospital, and certain manufacturers of equipment used in Brock's treatment. Since Aetna was the workers' compensation insurance carrier for Brock's employer, it was permitted to intervene so that it could protect its subrogation rights under section 5 of the Workers' Compensation Act (Ill. Rev. Stat. 1981, ch. 48, par. 138.5).

The aforementioned lawsuit was settled for $2,100,000. At the time of the settlement, the lien for workers' compensation benefits already paid by Aetna was $539,929.36, and as part of the settlement it was agreed that $350,000 would be paid to Aetna as the net recovery on its lien for benefits already paid. This $350,000 was a net figure, arrived at after deducting from the lien amount statutory attorney fees that would have otherwise been due on the lien amount and after deducting a portion of the pending lien amount which Aetna agreed to compromise in an effort to achieve the settlement.

The final order from which this appeal is taken requires Aetna to pay to an attorney for the conservator the sum of $20,678.65, the amount expended by the conservator's attorneys in preparation and presentation of the case. This order also calculates the amount of the proceeds that should be paid to the conservator as follows:

Aetna contends that the circuit court's calculation of the amount of the credit against future workers' compensation benefits is improper. In doing so, it relies upon Jones v. Melroe Division, Clark Equipment Co. (1981), 102 Ill. App.3d 1103, 430 N.E.2d 1385, and that court's construction of section 5(b) of the Workers' Compensation Act (Ill. Rev. Stat. 1981, ch. 48, par. 138.5(b)). Section 5(b) provides:

"Where the injury or death for which compensation is payable under this Act was caused under circumstances creating a legal liability for damages on the part of some person other than his employer to pay damages, then legal proceedings may be taken against such other person to recover damages notwithstanding such employer's payment of or liability to pay compensation under this Act. In such case, however, if the action against such other person is brought by the injured employee or his personal representative and judgment is obtained and paid, or settlement is made with such other person, either with or without suit, then from the amount received by such employee or personal representative there shall be paid to the employer the amount of compensation paid or to be paid by him to such employee or personal representative including amounts paid or to be paid pursuant to paragraph (a) of Section 8 of this Act.

Out of any reimbursement received by the employer pursuant to this Section, the employer shall pay his pro rata share of all costs and reasonably necessary expenses in connection with such third-party claim, action or suit and where the services of an attorney at law of the employee or dependents have resulted in or substantially contributed to the procurement by suit, settlement or otherwise of the proceeds out of which the employer is reimbursed, then, in the absence of other agreement, the employer shall pay such attorney 25% of the gross amount of such reimbursement."

Applying the formula for calculation of the credit involved in Jones ( 102 Ill. App.3d 1103, 1109-10), Aetna computes the credit to which it is entitled as follows:Gross Credit Net Credit

Secondly, we believe that Aetna's formula does not subtract the proper amount of attorney fees from the "gross credit." As noted above, Aetna had a lien for workers' compensation benefits already paid of $539,929.36. It agreed to accept $350,000 as its recovery on that lien, and this $350,000 figure was arrived at, in part, by deducting from the lien amount statutory attorney fees that would have otherwise been due on the lien amount. Thus, Aetna, in effect, has already paid attorney fees on $539,929.36 of the $2,100,000. Therefore, the gross credit should only be reduced by statutory attorney fees on $1,560,070.64, the difference between $2,100,000 and $539,929.36.

Accordingly, for the reasons stated above, we cannot accept Aetna's formula for the computation of the credit against future workers' compensation benefits.

Before stating what we believe is the proper formula for determination of the net amount of Aetna's credit, we address the other issues raised by Aetna. Aetna argues that the trial court's calculation of the credit to which it is entitled erroneously imposes a 33 1/3% attorney fee upon Aetna. Actually, the circuit court's computation of the credit did not expressly consider the conservator's attorney fees. The circuit court's order merely states that the credit to Aetna is equal to the net proceeds received by the conservator as a result of the settlement. The amount of the net proceeds, however, was determined, in part, by subtracting the conservator's attorney fees from the settlement amount. In the circuit court's computation, $700,000 in attorney fees were subtracted from the settlement of $2,100,000. Seven hundred thousand dollars is clearly 33 1/3% of the settlement figure.

• 2 Section 5(b) clearly provides: "[W]here the services of an attorney at law of the employee or dependents have resulted in or substantially contributed to the procurement by suit, settlement or otherwise of the proceeds out of which the employer is reimbursed, then, in the absence of other agreement, the employer shall pay such attorney 25% of the gross amount of such reimbursement." (Ill. Rev. Stat. 1981, ch. 48, par. 138.5(b).) Further, the words "in the absence of other agreement" have been construed by Illinois courts to refer to an agreement between the employer-intervenor and the employee or his attorney. ( Vandygriff v. Commonwealth Edison Co. (1979), 68 Ill. App.3d 396, 397, 386 N.E.2d 318; Kimpling v. Canty (1973), 13 Ill. App.3d 919, 922, 300 N.E.2d 839; Railkar v. Boll (1970), 125 Ill. App.2d 203, 206, 260 N.E.2d 851.) In the instant case, there was no such agreement between the employer or Aetna and the conservator or her attorneys. Thus, the only basis upon which the conservator's attorneys can recover attorney fees from Aetna is section 5 of the Workers' Compensation Act, and that statute specifically provides for an attorney fee of "25% of the gross amount of such reimbursement."

A 25% statutory attorney fee is appropriate in the instant case. Twenty-five percent of the settlement amount of $2,100,000 is $525,000. This $525,000, however, must be allocated between the amount reimbursed to Aetna for benefits already paid and the credit to Aetna against the payment of future workers' compensation benefits. Thus, the attorney fees on the amount reimbursed to Aetna, $539,929.36, are $134,982.34, and the attorney fees allocable to the credit are $390,017.66.

• 3 Aetna's last contention is that the circuit court's order improperly requires it to pay the litigation costs. We agree with Aetna's contention that the circuit court erred in requiring Aetna to pay all the litigation costs. Section 5(b) provides: "Out of any reimbursement received by the employer pursuant to this Section, the employer shall pay his pro rata share of all costs and reasonably necessary expenses in connection with such third-party claim, action or suit." Thus, the circuit court should have ordered Aetna to pay out of the money reimbursed to it its pro rata share of the litigation costs of $20,678.65. The pro rata litigation costs on the amount reimbursed to Aetna, $539,929.36, are $5,376.45. The remainder of the litigation costs, $15,302.20, should have been taken as a deduction in computing the amount of the credit to which Aetna is entitled.

In light of the aforementioned conclusions, we believe that the credit against the payment of future workers' compensation benefits to which Aetna is entitled should be computed as follows:
