Defendant, Hopkins & Hоward, P.C., appeals from the denial of its motion to dismiss which sought to compel arbitration in an action brought by plaintiff, Douglas D. Mueller, defendant’s former employee. We reverse and remand.
*185 On February 1, 1995, Mueller entered into an employment contraсt (hereinafter Agreement) with Hopkins & Howard, P.C. (hereinafter employer), a Missouri corporation located in Missouri. The Agreement contained an arbitration clause providing as follows:
Any claim or controversy between the parties arising out of or relating to this Agreement or the breach thereof, or in any way related to the terms and conditions of the employment of Doug Mueller by the Firm, shall be settled by arbitration under the rules of the American Arbitration Association and the laws of the State of Missоuri.
The Agreement did not contain a clause stating that the contract contained a binding arbitration provision enforceable by the parties. 1
Mueller’s employment responsibilities included audits, tax work, preparation of financial statements, and financial planning for clients. Some of employer’s clients were located in Illinois, so Mueller traveled there and sent various documents through the mail to them. In January 1997, Mueller voluntarily resigned from his employment.
In October 1997, Mueller brought the present aсtion against employer for declaratory judgment (Count I), mandamus (Count II), breach of contract (Counts III and IV), conversion (Counts V and VI), breach of fiduciary duty (Counts VII and X), accounting (Count VIII), and corporate dissolution (Count IX). Employer filed a motion to dismiss, alleging that thе parties expressly agreed that any disputes under the Agreement would be settled by arbitration. The trial court denied the motion to dismiss, but did not state the basis for its decision.
In its sole point on appeal, employer contends the trial court erred in refusing to dismiss Mueller’s action and to compel arbitration because the arbitration clause in the Agreement was enforceable. Mueller counters that the Federal Arbitration Act (hereinafter FAA) does not apply, that employer waived its right to arbitrаte, that there is no legal support for employer’s requested remedy of dismissal, and that the arbitration provision does not cover most of Mueller’s counts.
Because the issue of whether the FAA applies to the Agreement is determinative of othеr issues on appeal, we address that issue initially. The FAA applies to contracts evidencing transactions “involving commerce.” 9 U.S.C. section 2 (1994). The United States Supreme Court has held that Congress intended the FAA to reach the full expanse of its Commercе Clause power.
Duggan v. Zip Mail Services, Inc.,
Here, Mueller’s contract with employer involved interstate commerce. Employer was a Missouri corporation located in Missouri. As part of his employment responsibilities, Mueller served clients located in Illinois as well as Missouri. Mueller traveled to Illinois to conduct business *186 for employer. In addition, Mueller sent financial and tax documents across the state line to the Illinois clients and used the U.S. postal service to do sо. Thus, the Agreement affected commerce and was subject to the FAA.
We next consider Mueller’s contention that a motion to dismiss was the improper vehicle to raise the mandatory arbitration issue. Employer’s motion alleged that under the Agreemеnt any disputes thereunder were to .be settled by arbitration and requested the court to refer Mueller’s claims against it to arbitration. Although the trial court’s ruling was neither on a motion to compel arbitration nor on a motion to stay litigation, employer’s motion to dismiss sufficiently raised the arbitration issue.
Mr. Mudd, Inc. v. Petra Tech, Inc.,
Mueller challenges employer’s reliance on
Mr. Mudd
because, in contrast to
Mr. Mudd,
the ruling on employer’s motion to dismiss did not dispose of all parties or claims and was not final and appeal-able under section 512.020, RSMo (1994). In addition, the trial court made no express finding under Rule 74.01(b) that “there is no just reason for delay” for a judgment disposing of fewer than all claims or parties to be appealable. In
Young v. Prudential Securities, Inc.,
Mueller also argues that this court lacks jurisdiction to hear the appeal for the reason that Missouri’s Uniform Arbitration Act (hereinafter Missouri Act) does not apply because the Agreement did not contain the notice required by section 435.460, RSMo (1994) and because employer did not apply for arbitration under section 435.355, RSMo (1994). 3
The FAA permits an appeal from an order refusing a stay of litigation or an order denying a petition to order arbitration. 9 U.S.C. section 16(a)(1)(A)
*187
and (B) (1994). Although the Missouri Act does not allow an appeal from an order refusing a stay of litigation, section 4B5.440.1, RSMo (1994) provides for an appeal from “an order denying an application to compel arbitration made under said section 435.355.” Thus, the parties have the right to appeal from the trial court’s decision under either act and may do so if either act applies to the circumstances of the case.
Duggan,
Mueller also argues that the requisite notice “THIS CONTRACT CONTAINS A BINDING ARBITRATION PROVISION WHICH MAY BE ENFORCED BY THE PARTIES” required by section 435.460 is absent from the contract. The FAA preempts any stаte act and any additional burden imposed on the party seeking arbitration by the Missouri Act cannot defeat an arbitration clause covered by the FAA.
Reis v. Peabody Coal Co.,
Mueller further asserts that employer waived its right to arbitrate. The right to arbitrate under the FAA can be waived.
Id.
at 392. There is, however, a strong prеsumption against any such waiver.
Id.
We review waiver of arbitration rights
de novo. Reis,
A party waives its right to arbitrate if it (1) had knowledge of the existing right to arbitrate, (2) acted inconsistently with that right, and (3) prejudiced the party opposing arbitration.
Nettleton v. Edward D. Jones & Co.,
Mueller filed his petition on October 9, 1997. On December 19, 1997, employer filed its answer and affirmative defenses. Then, on July 1, 1998, after what Mueller refers to as “extensive written disсovery” had occurred, employer filed its motion to dismiss in which it raised the arbitration issue. Assuming, without deciding, that employer knew it had the right to arbitrate and its acts were inconsistent with that right, the prejudice prong is dispositive of the waiver issue. Prejudice may result from lost evidence, duplication of efforts, use of discovery methods unavailable in arbitration, or litigation of substantial issues going to the merits.
Nettleton,
Delay in seeking to compel arbitration does not itself constitute prejudice; but delay and the moving party’s trial-oriented activity are material factors in assessing prejudice.
Reis,
Here, Mueller alleges that he was prejudiced by employеr’s delay in seeking
*188
arbitration in that he responded to interrogatories, produced a substantial number of documents, researched and responded to employer’s affirmative defenses, and incurred substantial legal fees in so doing. Yet, Mueller did not sustain his burdеn to establish prejudice, despite the fact that a delay occurred. The fruits of the discovery and legal research may be usable in arbitration or may be relevant to those claims which both parties agree are not the subject of arbitration. Also, this is not a situation where employer filed a substantial number of motions to which Mueller was required to respond. In contrast, in
Reis,
Lastly, Mueller contends the arbitration provision did not cover most of the counts in the petition. The arbitration clause in the Agreement entered into between Mueller and employer provided that any claims or controversies “arising out of or relating to this Agreement or the breach thereof, or in any way related to thе terms and conditions of [Mueller’s] employment” must be settled by arbitration. We have reviewed the petition and find that Counts I, II, III, IV, VIII, and IX were brought by Mueller against defendant-employer and referenced the specific provisions of the Agreement with respeсt to each count. The remaining Counts V, VI, VII, and X were asserted against the other defendants and not against defendant-employer and did not reference specific provisions of the Agreement. The agreement to arbitrate therefore only rеlated to Mueller’s claims against employer set forth in Counts I, II, III, IV, VIII, and IX. The trial court erred in denying employer’s motion to dismiss and in refusing to compel arbitration of those counts. Employer’s point on appeal is granted.
The judgment of the trial court is reversed and the cause is remanded for action not inconsistent with this opinion.
Notes
. At issue in
Mr. Mudd
was whether defendants waived the right to arbitrate. The court properly concluded there was no waiver. To the extent
Mr. Mudd
implies that the denial of a motion to dismiss that raises the issuе of arbitration is not a final and appealable judgment until the trial court disposes of all parties and all claims,
see Mr. Mudd,
. Section 435.355 provides in pertinent part: "On application of a party showing an agreement [to arbitrate a controversy], and the opposing party’s refusal to arbitrate, the court shall order the parties to proceed with arbitration. ...”
. Section 435.460, RSMo (1994) provides as follows: "Each contract subject to the provisions of sections 435.350 to 435.470 shall include adjacent to, or above, the space provided for signatures a statement, in ten point capital letters, which read substantially as follows: 'THIS CONTRACT CONTAINS A BINDING ARBITRATION PROVISION WHICH MAY BE ENFORCED BY THE PARTIES.’ ”
