In this wrongful termination case, KB Home of South Carolina, Inc. and Jeff Meyer 1 (collectively Appellants) appeal a circuit court judgment denying their motion to compel arbitration. On appeal, Appellants contend the circuit court erred in: (1) determining the validity of an arbitration clause contained in Lonnie Davis’s employment application when that threshold determination was arguably for the arbitrator, (2) finding Appellants waived their right to enforce the arbitration clause by actively participating in litigation for eighteen months before seeking to compel arbitration, and (3) finding the alleged arbitration clause to be an unconscionable and unenforceable contract of adhesion. We affirm.
*121 FACTS/PROCEDURAL HISTORY
Davis applied for employment with KB Home on January 12, 2006. Davis’s employment application contained an arbitration clause, stating as follows:
I understand and agree that if employed, I will be required to arbitrate any disputes arising out of or related to my employment with or termination from the Company, including any claims for discrimination, harassment, retaliation and/or wrongful termination. I understand that only an arbitrator, not a judge or a jury, will hear such disputes. I further understand that this term and condition of my employment may not be changed except by written agreement specifically for such purpose entered into between myself and the Company and signed by the President of the division or the Company’s Sr. Vice President of Human Resources, and that such term and condition of my employment shall not be affected by any other employment policies or programs, in writing or otherwise, relating to other terms and conditions of my employment and that such policies and programs are subject to change at any time for any reason by the Company at its discretion and that I have no vested rights in any Company policy or program now or hereafter in effect.
(emphasis added). The employment application also stated “I understand that this application remains current for only 30 days.” Davis signed the employment application underneath the following statement: “I certify that I have read, fully understand and accept all of the above terms.”
On March 13, 2006, sixty days later, Davis was offered a position as the Vice President of Finance with KB Home. Davis signed an employment agreement containing a merger clause. The merger clause provided:
Entire Agreement: This letter together with the documents referenced herein contain all of the agreements and understandings regarding your employment and the obligations of KB Home in connection with employment. KB Home has not made, nor are you relying upon any oral or written promises or statements made by KB Home or any agent of KB Home except as expressly set forth herein. This letter supersedes any and all prior agreements and understand *122 ings between you and KB Home and alone expresses the agreement of the parties. This letter containing all of the agreements and understandings regarding your employment can only be amended in writing by the Senior Vice President, Human Resources of KB Home.
(emphasis added).
KB Home terminated Davis on July 20, 2007. Davis subsequently brought a lawsuit against Appellants on March 3, 2008, for breach of contract, breach of contract accompanied by a fraudulent act, violation of the South Carolina Payment of Wages Act, wrongful termination/retaliation, and defamation. Davis claimed he was fired for reporting numerous infractions by KB Home employees, including various managers’ demeaning and harassing conduct toward female employees as well as numerous fraudulent and unethical financial transactions in violation of the civil and criminal laws of South Carolina.
The parties engaged in discovery, filing multiple sets of interrogatories and requests for production of documents. Both Davis and Appellants produced documents and filed responses to the opposing parties’ interrogatories. In addition, Appellants noticed and rescheduled Davis’s deposition on five separate occasions. Appellants filed a motion to dismiss, which the circuit court heard and denied on January 9, 2009. A scheduling order was signed by the circuit court on April 30, 2009.
Davis filed a motion to compel discovery on July 13, 2009. Specifically, Davis suggested Appellants’ responses to Davis’s first set of interrogatories and requests for production were inadequate. On July 28, 2009, Appellants filed a motion for entry of a confidentiality order with respect to Davis’s discovery requests. On August 5, 2009, Appellants filed a memorandum in response to Davis’s motion to compel discovery. The parties consented to an amended scheduling order, which was signed on August 7, 2009.
In September of 2009, eighteen months after Davis filed his complaint, Appellants filed a motion to compel arbitration and to stay the proceedings. Davis filed a response to the motion to compel arbitration. Davis argued the merger clause in his subsequent employment agreement superseded the prior employment application containing an arbitration clause. Davis *123 further argued Appellants waived their right to seek arbitration by waiting eighteen months to file a motion to compel arbitration. Davis suggested the parties had engaged in extensive discovery, thereby giving Appellants an unfair advantage should the case go to arbitration. Finally, Davis argued the arbitration clause was an unconscionable contract of adhesion, and therefore unenforceable by an arbitrator.
The circuit court held a hearing on the motion to compel and denied the motion. The circuit court noted “[t]he reason for the denial is as set forth in [Davis’s] memorandum, all of the reasons stated.” 2 The circuit court issued a Form 4 judgment denying Appellants’ motion to compel arbitration on October 30, 2009. Appellants did not file a motion to alter or amend pursuant to Rule 59(e), SCRCP. This appeal followed.
ISSUES ON APPEAL
1. Is it for a court or an arbitrator to determine the threshold validity of an arbitration clause contained in Davis’s employment application when a merger clause in the resulting employment agreement arguably superseded the application thereby rendering the arbitration clause invalid, and when the employment application stated it would expire after 30 days?
2. Did KB Home and Meyer waive their right to enforce the arbitration clause in Davis’s employment application by actively participating in litigation for eighteen months before seeking to compel arbitration?
3. Is the arbitration clause an unconscionable and unenforceable contract of adhesion?
STANDARD OF REVIEW
“Arbitrability determinations are subject to
de novo
review.”
Simpson v. MSA of Myrtle Beach, Inc.,
LAW/ANALYSIS
I. Court versus Arbitrator
We first address the issue of whether it was proper for the circuit court, as opposed to an arbitrator, to address the threshold validity of the arbitration clause contained in Davis’s employment application.
“Unless the parties have contracted to the contrary, the FAA [Federal Arbitration Act] applies in federal or state court to any arbitration agreement regarding a transaction that in fact involves interstate commerce, regardless of whether or not the parties contemplated an interstate transaction.”
Munoz v. Green Tree Fin. Corp.,
“[E]ven in cases where the FAA otherwise applies, general contract principles of state law apply in a court’s evaluation of the enforceability of an arbitration clause.”
Simpson,
As the supreme court noted in Simpson, this distinction is insignificant as the UAA and FAA provisions at issue are nearly identical. Compare 9 U.S.C.A. §§ 2, 4 (West 2009), *125 with S.C.Code Ann. §§ 15-48-10(a), -20(a) (2005). The FAA provides: “The court shall hear the parties, and upon being satisfied that the making of the agreement for arbitration or the failure to comply therewith is not in issue, the court shall make an order directing the parties to proceed to arbitration in accordance with the terms of the agreement.” 9 U.S.C.A. §4 (West 2009) (emphasis added); accord S.C.Code Ann. § 15-48-20(a) (2005) (noting “if the opposing party denies the existence of the agreement to arbitrate, the court shall proceed summarily to the determination of the issue so raised and shall order arbitration if found for the moving party, otherwise, the application shall be denied”) (emphasis added).
“Arbitration is a matter of contract, and a party cannot be required to submit to arbitration any dispute which he has not agreed to submit.”
Zabinski v. Bright Acres Assocs.,
Arbitration clauses are severable from the contracts in which they are embedded.
S.C. Pub. Serv. Auth. v. Great
W.
Coal,
Appellants contend
Buckeye Check Cashing v. Cardegna,
Davis does not suggest his entire employment agreement was invalid. Rather, Davis contests only the validity of the arbitration clause contained in his employment application in light of the subsequent employment offer letter, which contained a merger clause. Therefore, Davis’s challenge is to the validity of the arbitration clause contained in his employment application. The employment application cannot be considered the entire employment agreement. We conclude Davis is making a specific challenge to the existence of the arbitration clause, and not a challenge to the entire employment agreement.

. Buckeye Check Cashing,
In addition, the arbitration clause in the instant matter did not expressly provide that any issues relating to the validity, existence, and scope of the arbitration agreement would be submitted to an arbitrator. Therefore, we hold the determination regarding whether a valid arbitration agreement existed was a “gateway matter” that the circuit court could properly consider.
Simpson,
*127 A. Merger Clause
Having concluded the circuit court properly considered Appellants’ arguments, as opposed to submitting them to an arbitrator, we proceed to address the arguments on the merits. Appellants contend the circuit court erred in concluding that the provisions of Davis’s employment application were superseded and rendered invalid by the presence of a merger clause in his subsequent employment agreement. We disagree.
To evaluate this argument, we look to South Carolina case law addressing merger clauses and contract interpretation.
Munoz,
“The parol evidence rule prevents the introduction of extrinsic evidence of agreements or understandings contemporaneous with or prior to execution of a written instrument when the extrinsic evidence is to be used to contradict, vary, or explain the written instrument.”
Gilliland v. Elmwood Props.,
“A merger clause expresses the intention of the parties to treat the writing as a complete integration of their agreement.”
Wilson v. Landstrom,
“The terms of a completely integrated agreement cannot be varied or contradicted by parol evidence of prior or contemporaneous agreements not included in the writing.”
Wilson,
By virtue of its express terms, the employment agreement at issue superseded any prior agreements. The employment agreement provided: “This letter together with the documents referenced herein contain all of the agreements and understandings regarding your employment and the obligations of KB Home in connection with employment.” Neither the employment application nor the arbitration clause contained therein was referenced in the subsequent offer letter agreement. The agreement further provided: “This letter supersedes any and all prior agreements and understandings between you and KB Home and alone expresses the agreement of the parties.”
*129
We conclude the merger clause was clear and unambiguous on its face.

In addition, the employment application at issue was executed two months prior to the employment agreement. Therefore, the arbitration clause in the application is not admissible to modify or add to the terms of the subsequent employment agreement containing a merger clause.
See Wilson,
Appellants cite
Ramirez-Baker v. Beazer Homes, Inc.,
We do not believe South Carolina law supports this conclusion.
See Blackwell,
While we recognize South Carolina law supports a policy favoring arbitration when a valid arbitration agreement exists, there is currently no exception to the merger clause rule in South Carolina for arbitration clauses in employment applications that are superseded by express language in a subsequent employment agreement.
See Munoz,
We affirm the circuit court’s finding that the merger clause contained in the employment offer letter operated to supersede the arbitration clause contained in the employment application. Accordingly, there was no arbitration clause to enforce, and the circuit court properly denied the motion to compel arbitration.
B. 30-day Expiration Clause
Appellants next argue that the arbitration clause was separate and distinct from the employment application, and therefore the 30-day expiration of the employment application did not apply to the arbitration clause contained therein. We need not address Appellants’ argument regarding the 30-day expiration of the employment application because we hold the merger clause was valid and binding. Therefore, the merger clause served to negate any prior or contemporaneous agreements not included in the final document.
See U.S. Leasing Corp.,
II. Waiver
Appellants further argue the circuit court erred in finding they waived their right to enforce the arbitration clause by engaging in litigation for an eighteen-month period prior to filing a motion to compel arbitration. Specifically, Appellants argue Davis cannot demonstrate any prejudice from the delay, and mere inconvenience is insufficient to demonstrate prejudice. We disagree, and we affirm the circuit court’s ruling on this alternative basis.
The right to enforce an arbitration clause may be waived.
Liberty Builders, Inc. v. Horton,
In
Rhodes v. Benson Chrysler-Plymouth, Inc.,
this court set out three factors a court generally considers when determining whether a party has waived its right to compel arbitration: “(1) whether a substantial length of time transpired between the commencement of the action and the commencement of the motion to compel arbitration; (2) whether the party requesting arbitration engaged in extensive discovery before moving to compel arbitration; and (3) whether the non-moving party was prejudiced by the delay in seeking arbitration.”
We first address whether a substantial length of time has passed between commencement of the action and the motion
*132
to compel arbitration. South Carolina case law varies with respect to what constitutes a “substantial length of time.”
Compare Evans v. Accent Manufactured Homes, Inc.,
We conclude a substantial length of time has passed in the instant matter. Appellants waited eighteen months after Davis filed his complaint to file their motion to compel arbitration and stay proceedings. No other South Carolina case has found that a party did not waive their rights to compel arbitration after a year and a half of litigation.
Regarding the second factor, we further conclude the parties have engaged in extensive discovery. Both Davis and Appellants produced documents and filed responses to the opposing parties’ interrogatories. Appellants noticed and rescheduled Davis’s deposition on five separate occasions. Davis filed a motion to compel discovery on July 13, 2009. Appellants filed a memorandum in response to Davis’s motion to compel discovery on August 5, 2009. All of the foregoing actions forced Davis to incur attorney’s fees that would not have been expended in arbitration. Under the facts of this case, we hold Davis was prejudiced by the costs he incurred in discovery.
See Evans,
Lastly, we note the parties have availed themselves of the circuit court’s assistance on several occasions. Appellants filed a motion to dismiss, which the circuit court heard and denied via a Form 4 judgment on January 9, 2009. Appellants filed a motion for entry of a confidentiality order with respect to Davis’s discovery requests on July 28, 2009. An initial scheduling order was signed by the circuit court on April 30, 2009. Finally, the parties consented to an amendéd scheduling order, which was signed by the Chief Administrative Circuit Court Judge on August 7, 2009. Pursuant to the terms of the amended scheduling order, this case was subject to being called for trial on or after February 15, 2010.
Even if the arbitration clause in Davis’s employment application had been valid and binding, we affirm the circuit court’s denial of Appellants’ motion to compel arbitration on the alternative basis that Appellants waived their right to enforce the arbitration agreement. Although the parties have not taken any depositions, a substantial length of time has passed, the parties have engaged in extensive discovery, and the parties have availed themselves of the circuit court’s assistance on several occasions.
III. Unconscionable Contract of Adhesion
Finally, Appellants argue the circuit court erred in finding the arbitration agreement was an unconscionable contract of adhesion. Because we hold the merger clause in the employment agreement nullified the existence of the arbitration clause contained in the employment application, we need not reach the merits of this issue.
Futch,
CONCLUSION
For all of the foregoing reasons, the decision of the circuit court is
AFFIRMED.
Notes
. Jeff Meyer was the immediate supervisor of Lonnie Davis, the plaintiff in this action.
. Davis's Memorandum in Opposition to the Motion to Stay and Refer to Arbitration was included as part of the Record on Appeal.
. During oral argument, Appellants contended this court is bound to reviewing the terms of the arbitration clause itself in determining its validity. We disagree. The South Carolina Supreme Court has looked outside the language of the arbitration clause to determine its enforceability.
See Simpson,
. Even if this court were to view the merger clause as ambiguous, any ambiguity must be construed against the drafter of the contract, in this case KB Home.
