Shepherd, P.J.

This case involves a construction contract dispute between a general contractor, defendant Spence Brothers, Inc., and a subcontractor, plaintiff Gordon Sel-Way, Inc., which was submitted to arbitration pursuant to the terms of their October 9, 1978, contract. A three-member arbitration panel awarded $1,572,442.12 plus $343,007.79 in interest to plaintiff on November 5, 1986. Two days later, plaintiff commenced this action under MCR 3.602(1) in Washtenaw Circuit Court to confirm the award. Defendant responded by filing an application under MCR 3.602(J) and (K) to vacate or modify the award. Pursuant to a judgment dated July 24, 1987, and related opinions and orders, the trial court confirmed the award of $1,572,442.12, but vacated the interest award because there was no contractual basis for pre-award interest. However, the trial court allowed interest of five percent per annum commencing from the date of the arbitration award and continuing until payment. Defendant appeals as of right, seeking to vacate the award due to alleged "evident partial *119 ity” by one of the arbitrators and the failure of the arbitrators to state which of plaintiffs multiple claims were the bases of the award. Plaintiff cross-appeals from the interest award. We affirm.

We first consider defendant’s assertion that the award should be vacated due to alleged "evident partiality” of arbitrator Charles R. Scales, Jr. The trial court’s authority to vacate the arbitration award stems from MCR 3.602(J)(l)(b) which states that "the court shall vacate an award if . . . there was evident partiality by an arbitrator.” Here, as in other arbitral proceedings, the procedure established to safeguard the arbitral process against claims of partiality is one of disclosure. Under Rule 19 of the American Arbitration Association’s Construction Industry Arbitration Rules, which governed the parties’ arbitration, the aaa determines whether an arbitrator should be disqualified upon disclosure by the appointed arbitrator.

The problem in this case is that arbitrator Charles Scales did not fill out and return the aaa’s required "notice of appointment” form which required a disclosure of "any past or present relationship with the parties or their counsel, direct or indirect, whether financial, professional, social or other kind.” The information that the defendant claims should have been disclosed at the time of Charles Scales’ appointment in November, 1985, was his association with the consulting engineering firm of Scales & Associates, Inc., and the fact that Charles Scales filed a lawsuit as the attorney for the Scales consulting firm against the defendant corporation in 1984. Charles Scales’ status as the president of the consulting firm was disclosed in his biographical sketch provided by the aaa to *120 the parties and, hence, the central issue before us is whether Charles Scales’ failure to disclose that he filed the lawsuit on behalf of his consulting firm is grounds for vacating the award. We conclude that it is not.

It has been held that an arbitrator’s failure to disclose certain facts which might reasonably lead to an impression of bias constitutes grounds for vacating the award. Albion Public Schools v Albion Education Ass’n, 130 Mich App 698, 701; 344 NW2d 55 (1983), lv den 419 Mich 944 (1984). However, the failure to disclose does not per se require that the award be vacated. The questions presented by the parties in this appeal require consideration of two important qualifications on the relief available to the complaining party.

The first qualification is that a party’s failure to raise the disqualification issue in the arbitral proceeding may constitute a waiver. A waiver has been described as follows:

"Waiver is the intentional relinquishment of a known right. . . . The usual manner of waiving a right is by acts which indicate an intention to relinquish it, . . . or by so neglecting and failing to act as to induce a belief that it was the intention and purpose to waive.” [Maxey v Proctor, 343 Mich 453, 457; 72 NW2d 198 (1955), quoting Bailey v Jones, 243 Mich 159, 162; 219 NW 629 (1928).]

Waiver in an arbitration case has been defined as consisting of knowledge, actual or constructive, in the complaining party of the tainted relationship or interest of the arbitrator. International Brotherhood of Teamsters, Local Union 560 v Bergen-Hudson Roofing Supply Co, 159 NJ Super 313; 387 A2d 1246 (1978).

The second qualification is that, to overturn the *121 arbitration award, the partiality or bias must be certain and direct, not remote, uncertain or speculative. Belen v Allstate Ins Co, 173 Mich App 641, 645; 434 NW2d 203 (1988); Kauffman v Haas, 113 Mich App 816, 819; 318 NW2d 572 (1982). Although the trial court based its decision not to vacate the award on the waiver issue, we conclude that a consideration of both qualifications supports the court’s decision not to vacate the award.

The record submitted by the parties on the disqualification issue consisted of the record of the arbitration proceedings, affidavits, and documentary proofs. While there were some factual disputes established by this record, the trial court did not resolve the disputes but rather based its decision on undisputed facts. Those facts that were not disputed established that there is no basis for vacating the award due to "evident partiality.”

Addressing first the waiver issue, the record indicates that Charles Scales did in fact file a lawsuit against the defendant in 1984 on behalf of his consulting firm. The lawsuit was commenced in September, 1984, in an effort to collect on a debt owed to the consulting firm by Olympian Sprinkler, Inc., for shop drawings prepared by the consulting firm. Olympian was then a subcontractor on a construction project at the University of Michigan. The general contractor was Spence Brothers, Inc., the defendant in this case. Although the consulting firm’s contract was with Olympian, it named the defendant as a party on the theory that the defendant, as the general contractor, might owe Olympian for the shop drawings. The case was settled two months later when the project manager for the defendant, Thomas Spence, sent a joint check for $2,279 to Olympian and the consulting firm to settle the matter. As project manager, Thomas Spence was *122 responsible for all administrative matters relating to the project, including litigation.

By contrast, the project manager of the project underlying the instant arbitration action was the president of the defendant, Herbert Spence. The project entailed construction of a portion of the Ann Arbor Waste Water Treatment Plant. Defendant was the general contractor for the project and the plaintiff, Gordon Sel-Way, was a subcontractor responsible for excavation work.

Plaintiff originally filed an arbitration claim for about $900,000 in 1982 under a subcontract, but the proceedings were adjourned by mutual consent while settlement negotiations were pursued with the project owner. In November, 1985, Charles Scales was appointed as a member of the arbitration panel. Arbitration proceedings commenced in January, 1986, on an amended claim for $4,000,000 and terminated in November, 1986, when the panel reached a decision. Hugh Spence, the vice-president of the defendant and the project superintendent, appeared at the arbitration hearing on behalf of the defendant. According to Hugh Spence’s affidavit, he shared responsibility for the management of the project, including litigation, with Herbert Spence.

There is some conflict in the evidence regarding whether Charles Scales made a disclosure of his participation in the 1984 lawsuit prior to the arbitration hearing. On the one hand, Charles Scales asserted in a December, 1986, memorandum to the aaa that he may not have disclosed some information regarding a previous relationship with the defendant and "had forgotten” that the defendant was named as a party in the prior lawsuit. On the other hand, Charles Scales averred in a January, 1987, affidavit that he made a disclosure of the lawsuit when the arbitration hearing com *123 menced on January 7, 1986, although the transcript of the hearing and the affidavit of other participants do not support this assertion. We note that these factual disputes might never have occurred had the aaa not permitted the hearing to begin without first obtaining the required form from Charles Scales.

However, there was no dispute that at least two agents of the defendant had knowledge of the prior relationship between the defendant and Charles Scales in his status, as agent for the consulting firm. Thomas Spence acquired knowledge through his role as project manager of the University of Michigan project, while Herbert Spence acquired knowledge as president of the defendant in 1985 when he undertook to contact Charles Scales regarding a court notice of the lawsuit that was sent to the defendant in error. In a letter dated March 6, 1985, to the court, Herbert Spence explained:

Enclosed is a copy of Notice of Court Appearance received by us for March 19, 1985.

Since we had no knowledge of this case we contacted Mr. Charles R. Scales, Jr.

We were informed by Mr. Scales that the Notice was sent to Spence Brothers in error and that we should disregard.

Please confirm with Mr. Scales if necessary.

The trial court imputed the knowledge of Thomas and Herbert Spence to the defendant and thereafter concluded that the defendant’s failure to act on the knowledge in the arbitral process by objecting to Charles Scales’ alleged partiality constituted a waiver. We agree with the trial court.

A corporation is merely a legal fiction acting through its officers and agents. Bruun v Cook, 280 *124 Mich 484; 273 NW 774 (1937). One of the burdens of acting under the corporate form is that the law will impute the knowledge of individual officers and employees at a certain level of responsibility to the corporation:

The knowledge of individual officers and employees at a certain level of responsibility will be deemed the knowledge of the corporation; where the level of responsibility begins must be discerned from the circumstances of each case. Whether employees can be considered managerial employees so as to impute their actions to the corporation does not necessarily hinge on their level in the corporate hierarchy, but depends on the degree of discretion the employee has in making decisions that will ultimately determine corporate policy. [18B Am Jur 2d, Corporations, § 1673, pp 524-525.]

This Court has recognized that the combined knowledge of employees may be imputed to a corporation. People v American Medical Centers of Michigan, Limited, 118 Mich App 135, 155-156; 324 NW2d 782 (1982), lv den 417 Mich 985 (1983), cert den sub nom Fuentes v Michigan, 464 US 1009 (1983). We agree with this rule and adopt the standard for imputed collective knowledge set forth in Copeman Laboratories Co v General Motors Corp, 36 F Supp 755, 762 (ED Mich, 1941):

When a person representing a corporation is doing a thing which is in connection with and pertinent to that part of the corporation business which he is employed, or authorized or selected to do, then that which is learned or done by that person pursuant thereto is in the knowledge of the corporation. The knowledge possessed by a corporation about a particular thing is the sum total of all the knowledge which its officers and agents, who are authorized and charged with the doing of *125 the particular thing acquire, while acting under and within the scope of their authority.

Given the managerial responsibilities of Thomas and Herbert Spence and the underlying facts establishing their knowledge of Charles Scales’ involvement in a prior lawsuit against the corporation, we conclude that the trial court properly imputed their knowledge to the defendant and that the defendant’s failure to act on that knowledge by objecting to Charles Scales’ partiality constitutes a waiver. The fact that the individual agents of the defendant may not have personally connected Scales’ name to the prior lawsuit until after the arbitration award was entered does not mandate a different conclusion. Even where there are changes in a corporation’s personnel, i.e., a new president is appointed, a corporation, once charged with knowledge of a particular transaction or event, continues to be affected by such knowledge. See 18B Am Jur 2d, Corporations, § 1678, p 529; Microbiological Research Corp v Muna, 625 P2d 690 (Utah, 1981).

It follows that a corporate agent will not be allowed by the law to shut his or her eyes to the knowledge imputed to the corporation, but is required to carry out his or her duties in light of that knowledge even if the individual involved did not have personal knowledge of the fact in dispute. Here, Herbert Spence acquired knowledge of the prior lawsuit in the course of his authority as president of the corporation. The corporation did not act on that knowledge, or the other knowledge imputed to the corporation through Thomas Spence, when Herbert Spence performed his managerial responsibilities as project manager of the water treatment project. Based on this record, we conclude that the trial court correctly determined *126 that the defendant waived any objection to Charles Scales’ alleged partiality. In some cases such an analysis may appear harsh, but doing business in the corporate form carries certain burdens of which this is one.

The harshness is mitigated in this case because we are also able to uphold the trial court’s decision by reason of the peripheral nature of the alleged partiality. On the one hand, the defendant argues that the trial court transformed "isolated events” and minimal contact to actual knowledge of a prior conflict of interest. On the other hand, the defendant asserts that Charles Scales’ participation in the lawsuit of his consulting firm against the defendant in an effort to collect on a debt owed by Olympian caused "hard feelings.” The amount of the debt was minimal and was resolved by settlement two months after the lawsuit was filed. Defendant was added as a party in the prior action not because the Scales consulting firm had a dispute with it, but only because defendant might have owed money to the party who was indebted to the Scales consulting firm. Except for an error of the district court in keeping the case on its docket, the entire matter was resolved over one year prior to Charles Scales’ appointment as an arbitrator. We conclude that the possibility of partiality or bias by Charles Scales as a result of this lawsuit is too remote and speculative to overturn the arbitration award. There is no "evident partiality” and, hence, no basis for vacating the award.

Next, the defendant asserts that the arbitration award of $1,572,442.12 is erroneous on its face for failure to list the awards made on each of plain *127 tiffs multiple claims. Defendant asserts that an itemized award is necessary to determine whether the award is contrary to the contract provisions.

In DAIIE v Gavin, 416 Mich 407, 428-429; 331 NW2d 418 (1982), our Supreme Court observed that there is no requirement that a verbatim record of private arbitration proceedings be made or that the arbitrator specify findings of fact or conclusions of law:

Thus, from the perspective of the record alone, a reviewing court’s ability to review an award is restricted to cases in which an error of law appears from the face of the award, or the terms of the contract of submission, or such documentation as the parties agree will constitute the record.

The standard of judicial review from the private arbitration award, as adopted in Gavin, supra, p 443, quoting Howe v Patrons’ Mutual Fire Ins Co of Michigan, 216 Mich 560, 570; 185 NW 864 (1921), is:

"[Wjhere it clearly appears on the face of the award or the reasons for the decision as stated, being substantially a part of the award, that the arbitrators through an error in law have been led to a wrong conclusion, and that, but for such error, a substantially different award must have been made, the award and decision will be set aside.”

See also, Belen, supra, pp 644-645; The Hayman Co v Brady Mechanical, Inc, 139 Mich App 185; 362 NW2d 243 (1984).

Here, there is no clear error on the face of the award. Since the arbitrators had no duty to make a separate award for each claim, their failure to do so was not error and, hence, is not grounds for *128 vacating the award. Therefore, we conclude that the trial court correctly upheld the award.

By way of cross-appeal, plaintiff contends that the trial court erred by vacating the arbitration award of $343,007.79 in pre-award interest and by limiting post-award interest to five percent per annum. We disagree.

With regard to the pre-award interest of $343,007.79, plaintiff contends that it is conceivable that the arbitrators intended to award interest as damages to compensate plaintiff for its lost use of funds and, hence, the award must stand. The trial court vacated the interest award because there was no contractual basis for interest.

Michigan has long recognized the general rule that interest may be awarded as an element of damages to compensate for the lost use of funds in an action based on contract or tort. Banish v Hamtramck, 9 Mich App 381; 157 NW2d 445 (1968), lv den 381 Mich 779 (1968); Grand Trunk W R Co v H W Nelson Co, 116 F2d 823 (CA 6, 1941), reh den 118 F2d 252 (1941); and see Matich v Modern Research Corp, 430 Mich 1, 7, n 2; 420 NW2d 67 (1988). The questions that arise generally concern the date from which interest may accrue, the lawful rate of interest, and the existence of any statutory authority for the interest. See Vannoy v City of Warren, 26 Mich App 283; 182 NW2d 65 (1970), aff'd 386 Mich 686 (1972) (holding that, in a wrongful death action, a jury awards interest as part of its general verdict where a claim accrues as of a date certain and, upon the verdict being entered, statutory interest is paid).

With regard to when interest accrues in an *129 action based on contract, there has been an increased tendency to depart from standards based upon whether the claim is liquidated or ascertainable. See Dobbs, Remedies (Hornbook Series, 1973), p 174; Ramada Development Co v US Fidelity & Guaranty Co, 626 F2d 517 (CA 6, 1980). While Michigan case law developed by making distinctions between liquidated and unliquidated damages, the focus is on whether the award of interest is necessary to allow full compensation:

The concept that interest should be allowed as part of the damages for a delay in paying the principal damages was not readily accepted. As the law developed exceptions were made, and in particular cases the jury, or the trial judge as a matter of discretion, was permitted to allow interest as part of the damages. As case law defined those areas in which interest would be assessed as part of the damages, restrictions were placed on the unfettered exercise of jury and trial judge discretion.

It came to be a familiar principle that generally interest will be included as a matter of right where the amount claimed is "liquidated,” but not where the claim is "unliquidated.” Definitions of "liquidated” were not always consistent, and close cases created much confusion, until even the liquidated-unliquidated standard approached coalescence. In Cree Coach Company v Wolverine Insurance Company (1962), 366 Mich 449 [115 NW2d 400] interest was allowed from the date of loss on an unliquidated amount which, said the Court, "was known or could have been easily ascertained” (p 463). McCormick contends that interest should be includible except where the damages are "at large” and thus, in the last analysis, depend upon the discretion of the trier of fact uncontrolled by any meaningful standard except overall reasonableness. McCormick on Damages, § 57, page 226.

The cases are in conflict. Interest has been de *130 nied on the ground that the claim was unliquidated. Nevertheless, interest has been allowed on unliquidated claims.

We are persuaded the Michigan cases that allow interest as part of the damage in order to accomplish full compensation focus on the objectively sound facet of the matter. Although that principle seems clear, the difficult question of what is full compensation, neither excessive nor inadequate, is still very much with us. [Banish, supra, pp 395-396, 399.]

With regard to interest on contracts, our Supreme Court stated in Amluxen v Eugene J Stephenson, Inc, 340 Mich 273, 275-276; 65 NW2d 807 (1954), quoting Mitchell v Reolds Farms Co, 268 Mich 301, 311; 256 NW 445 (1934):

"The question of interest is purely statutory. Kermott v Ayer, 11 Mich 181 [1863]; Tousey v Moore, 79 Mich 564 [44 NW 958 (1890)]. Though interest is generally a matter of contract, the written contracts here involved do not provide for interest. 'It is a question of damages not of positive agreement.’ O’Connor v Beckwith, 41 Mich 657 [3 NW 166 (1879)]. 'No implied contract can grow up under which interest can be recovered.’ Regents of the University of Michigan v Rose, 45 Mich 284, 300 [7 NW 875 (1881)]. 'After default interest is strictly allowable only as damages.’ Mason v Callender, 2 Minn 350 (72 Am Dec 102). Hubbard v Callahan, 42 Conn 524 (19 Am Rep 564), for lost use. Boyce v Boyce, 124 Mich 696 [83 NW 1013 (1900)]. 'Failure to pay money promised when by law it ought to be paid, authorizes the allowance of interest in the nature of damages for the improper detention of the sum so promised.’ McCreery v Green, 38 Mich 172, 185 [1878]. 'Interest is allowed where money is withheld, either upon the ground of a promise, express or implied, to pay *131 interest or as damages for default in retaining money due and owing another. But upon whatever ground it may be placed, in the absence of an express promise, until the principal becomes due, no promise to pay interest can be implied, or be awarded as damages.’ Lake Shore & Michigan Southern R Co v People, 46 Mich 193, 211; [9 NW 249 (1881)].”

Here, it is conceivable, as argued by plaintiff, that the arbitrators intended to award interest as an element of damages in order to fully compensate plaintiff. However, it has been said that preaward interest is not permitted in an award resulting from arbitration on the theory that the defendant is not contractually obligated to pay the damage until the award is entered. See Osinski v DAIIE, 69 Mich App 426; 245 NW2d 426 (1976). Although the Osinski Court reached its finding regarding the accrual date of the contractual obligation rather summarily, we agree with its rationale.

Under the terms of the contract at issue here, the parties agreed to submit all claims and disputes to arbitration. The contract contained no provision for interest or payment while a dispute was pending in arbitration. Until such time that the arbitrators resolved the dispute and made an award, the defendant simply had no contractual duty to pay plaintiff. Since the principal damages were not due until the arbitration award was entered, it follows that there was no basis for making an award of interest as damages, even if it was intended to accomplish full compensation. Amluxen, supra. Hence, having considered the remedy agreed to by the parties to resolve any dispute, we conclude that the arbitrators erred as a matter of law in awarding pre-award interest to plaintiff. The error is plain from the face of the *132 award and, therefore, the trial court’s decision to vacate the interest award is affirmed.

Finally, with regard to plaintiffs challenge to post-award interest of five percent per annum commencing on the date of the arbitration award, we find no error. The interest was authorized by MCL 438.7; MSA 19.4, which, in an action based on contract, provides that it "shall be lawful . . . to allow and receive interest” upon an award of money ascertained or liquidated by award of arbitrators. The interest under the statute begins to accrue on the date of the award, and the legal rate of interest under the usury statute, MCL 438.31; MSA 19.15(1), is five percent per annum. Osinski, supra, pp 428-429.

We reject plaintiffs assertion that the judgment interest statute, MCL 600.6013; MSA 27A.6013, applied to the arbitration award. This statute provides in pertinent part that "[ijnterest shall be allowed on a money judgment recovered in a civil action.” In Morgan v Kamil, 144 Mich App 171, 173-174; 375 NW2d 378 (1985), lv den 422 Mich 970 (1985), this Court held:

MCL 600.6013; MSA 27A.6013 allows interest only on money judgments recovered in civil actions; it does not authorize interest on an arbitration award and the judgments entered confirming the award. The Legislature intended MCL 600.6013; MSA 27A.6013 to apply only to judgments obtained in civil actions, through court proceedings, not arbitration.

Accord, Osinski, supra; Moultrie v DAIIE, 123 Mich App 403; 333 NW2d 298 (1983); Western Casualty & Surety Co v Garden City, 151 Mich App 83, 89; 390 NW2d 687 (1986). We agree with these decisions and, therefore, affirm the trial *133 court’s decision to limit the interest award to five percent per annum beginning on the date of the arbitration award and continuing until payment.

Affirmed.
