In this appeal from the district court’s order granting summary judgment, we are called upon to determine whether it was proper for the trial court in confirming the arbitration award to make an award of attorney fees that were incurred during the course of arbitration proceedings, and whether prejudgment interest may be awarded on general damages commencing from the time of injury.
On June 29, 1987, the plaintiff-respondent, Carol Emery, was a pedestrian injured when a car driven by James Porter, struck her in a crosswalk. Porter was an underinsured motorist whose liability insurance policy paid Emery $20,000.00. Emery made a claim against her insurer, defendant-appellant United Pacific Insurance Co., under the underinsured motorist provisions of her policy which had limits of $300,000.00.
On September 16,1988, Emery submitted a formal proof of loss to United Pacific describing the facts of the accident, her injuries, diagnosis, prognosis and special damages she had incurred as a result of the accident. Counsel for Emery valued her case at $625,000.00. In response to the claim, Emery received a letter from United Pacific dated October 18, 1988, in which it demanded credit for the $20,000.00 paid by Porter’s insurance carrier and offered an additional $28,000.00 in compensation. Emery rejected United Pacific’s offer and on November 30, 1988, filed suit in the district court for damages, prejudgment interest, attorney fees, costs and a declaratory judgment action. On January 4, 1989, after the district court action had been filed, United Pacific filed a petition to compel arbitration pursuant to I.C. § 7-9021 and upon the arbitration clause contained in the insurance policy. The district court ordered arbitration on the limited issue of the amount of damages to which Emery would be entitled under the underinsured motorist provisions clause of her insurance policy.
The arbitration panel awarded Emery $281,853.96 in damages. Thereafter, the *246parties executed a Satisfaction of Award in the amount of $280,000.00. Emery then filed a Motion for Confirmation of Arbitrator’s Award and a Motion for Summary Judgment on the following issues: 1) Whether Emery was entitled to prejudgment interest from the date of the accident; and 2) Whether Emery was entitled to attorney fees and costs. The district court granted Emery’s motions and held that she was entitled to prejudgment interest from the date of the accident until the date the award was satisfied, and pursuant to I.C. § 41-1839 awarded Emery attorney fees in the amount of $49,381.25. United Pacific appeals from the summary judgment awarding Emery prejudgment interest and attorney fees.
I.
Award of Attorney Fees
Emery sought an award of attorney fees and costs pursuant to I.C. §§ 12-120(3), 12-121, 41-1839, and I.R.C.P. 54(d)(1). The trial court found that United Pacific had not acted frivolously so as to base an award of attorney fees under I.C. § 12-121 and I.R.C.P. 54(d)(1), and that the case was not within the scope of I.C. § 12-120(3) since it was not a commercial transaction as defined by the statute.
However, the trial court ruled pursuant to I.C. § 41-1839 that United Pacific was obligated to pay Emery’s attorney fees incurred during the entire litigation process, including the arbitration proceedings. United Pacific appeals this award of attorney fees asserting that pursuant to I.C. § 7-910 and the arbitration clause contained in the insurance contract, attorney fees should not have been awarded to the extent that they were incurred during an arbitration proceeding. United Pacific concedes that pursuant to I.C. § 41-1839, an insured who recovers in a court action to enforce the terms of a contract is entitled to an award of attorney fees. However, United Pacific argues that if a party to a contract, including an insurance contract, invokes the arbitration clause, attorney fees incurred during the arbitration proceeding are not recoverable.
I.C. § 7-910 states,
Unless otherwise provided in the agreement to arbitrate, the arbitrator’s expenses and fees, together with other expenses, not including counsel fees, incurred in the conduct of the arbitration, shall be paid as provided in the award. (Emphasis added.)
With regard to I.C. § 7-910, this Court has interpreted the statute to provide that it is beyond the scope of an arbitrator’s powers to award attorney fees to one of the parties absent a contractual agreement to do so. Bingham County Comm’n v. Interstate Elec. Co., 105 Idaho 36, 665 P.2d 1046 (1983). However, that limitation upon an arbitrator does not extend to the authority of the district court to award attorney fees pursuant to I.C. § 41-1839.
The arbitration clause contained in the United Pacific insurance contract2 states that unless the parties object, arbitration will be conducted under the rules of the American Arbitration Association. A review of the record demonstrates that no objection was made to the arbitration proceedings being conducted under those rules. The American Arbitration Association Rules contain the following relevant provisions which state:
The expenses of witnesses for either side shall be paid by the party producing such witnesses. All other expenses of the arbitration, including required travelling and other expenses of the arbitrator and AAA representatives, and the expenses of any witness and the cost of any proof produced at the direct request of the arbitrator, shall be borne equally by the parties, unless they agree other*247wise or unless the arbitrator in the award assesses such expenses or any part thereof against any specified party or parties.
As the above rule states, the general rule of arbitration proceedings is that the parties must bear equally all expenses of arbitration except those expenses of witnesses which are to be paid by the party producing such witnesses. However, as provided in the American Arbitration Rules, the parties may agree to modify this rule in any manner that they choose.
This Court has previously held that the provisions of I.C. § 41-1839 become part of the insurance contract to the same effect as though incorporated therein. Pendlebury v. Western Casualty & Sur. Co., 89 Idaho 456, 406 P.2d 129 (1965). I.C. § 41-1839 provides in pertinent part:
41-1839. Allowance of attorney fees in suits against insurers. — (1) Any insurer issuing any policy, certificate or contract of insurance, surety, guaranty or indemnity of any kind or nature whatsoever, which shall fail for a period of thirty (SO) days after proof of loss has been furnished as provided in such policy, certificate or contract, to pay to the person entitled thereto the amount justly due under such policy, certificate or contract, shall in any action thereafter brought against the insurer in any court in this state for recovery under the terms of the policy, certificate or contract, pay such further amount as the court shall adjudge reasonable as attorney’s fees in such action ... (Emphasis added.)
Pursuant to this implied term in the insurance contract, the parties agree that the insurer is obligated to pay attorney fees if the insured is compelled to file suit to recover under the insurance policy. As an implied term in the insurance contract, the statutory language of I.C. § 41-1839 modifies the general American Arbitration Association rule that the parties must bear equally all expenses of arbitration, except those associated with the presentation of witnesses. Where the insured is required and compelled to file a lawsuit by reason of an insurer’s refusal to pay in order to recover under her insurance contract, we hold it is implicit in I.C. § 41-1839 that the court shall adjudge a reasonable award of attorney fees against the insurer.3 This Court has further held that the attorney fee authorized by I.C. § 41-1839 is not a penalty, but an additional sum rendered as just compensation. Halliday v. Farmers Ins. Exch., 89 Idaho 293, 404 P.2d 634 (1965). We affirm the trial court’s award of attorney fees.
II.
Prejudgment Interest
In the instant action the trial court ruled that Emery was entitled to prejudgment interest on the entire award from the date of the accident. United Pacific argues that this was error in that the general damages portion of the award was unliquidated, and not reasonably ascertainable. United Pacific asserts that Emery was not entitled to recover prejudgment interest until the amount of damages was determined by the arbitrator and a decree entered. We disagree.
In awarding prejudgment interest, the trial court relied on our recent holding in Brinkman v. Aid Ins. Co., 115 Idaho 346, 766 P.2d 1227 (1988). In Brinkman, the insured was similarly injured by an under-insured motorist. The insurer, Aid Insurance Company, refused to pay Brinkman, causing him to file suit to recover under the underinsured motorist clause of his insurance policy. A jury returned a verdict awarding Brinkman $156,000 in damages. The trial court in Brinkman looked to I.C. § 28-22-104(1) which provides for prejudgment interest on “money due by express contract” and found that Brinkman was entitled to prejudgment interest from the date of the accident on the medical bills which became due and owing prior to suit *248and which were not timely paid by Aid. Brinkman appealed asserting that prejudgment interest should have been allowed upon the entire amount of the jury award including the general damages. Pursuant to I.C. § 28-22-104(1), this Court held in favor of Brinkman stating,
It is significant that Aid’s duty arose out of a contract between Aid and Brinkman, not out of a tort action. Because Aid contracted to insure Brinkman for up to $300,000 for all injuries and losses suffered at the hands of an underinsured tortfeasor, Aid is liable for prejudgment interest on the entire amount awarded by the jury. Prejudgment interest accrues on the general damages from the date of the accident, because that is the date Aid’s contractual duties accrued.
115 Idaho at 353-54, 766 P.2d at 1234-35.
The facts presented in the instant case are strikingly similar to those in Brink-man. We therefore hold it was not error for the trial court to award prejudgment interest upon the entire award commencing from the date of the accident.
It is important to note that the Brink-man decision is applicable to a very limited set of facts. The Brinkman decision is not, as the appellant contends, applicable to all tort actions, or all contract actions. The Brinkman decision is limited to actions based on first party insurance contract actions involving an underinsured motorist clause similar to the one contained in Brinkman’s insurance policy. In a situation such as this, where an insured files suit against his or her own insurance company for payment under an underinsured motorist clause, the insured is entitled to prejudgment interest on the entire award, including the award for general damages, from the time of injury. Brinkman v. Aid Ins. Co., 115 Idaho 346, 766 P.2d 1227 (1988). Therefore, we affirm the trial court’s award of prejudgment interest on the entire damage award beginning from the date of the accident.
The trial court’s order is affirmed in all respects. Costs to respondent. No fees awarded.
