*306 PER CURIAM.
Plaintiff Amerisure Insurance Company appeals by right the circuit court's order granting summary disposition to defendants Graff Chevrolet, Inc. (Graff), and Chrysler Corporation. This case involves a dispute between two insurance companies arising from an automobile accident. The vehicle involved in the accident was owned by Graff. However, the vehicle was driven by an employee of plaintiff's insured, a Hungry Howie's Pizza store. We affirm in part and reverse in part.

I
While her car was being repaired, Debra Rahn rented a Chevrolet Corsica from Graff. The substitute vehicle agreement (also known as a rental car contract) listed Richard Threehouse, Rahn's fiance, as a permissive user of the car. However, the contract stated that insurance coverage was excluded when the rental car was used "to carry ... property for consideration...." On January 30, 1994, while he was driving the Corsica and delivering pizzas for his employer, Hungry Howie's Pizza, Threehouse collided with another car. The other driver sued Graff, Threehouse, and Hungry Howie's. Ultimately, the claim was settled for $180,000. Because plaintiff and defendant Chrysler Corporation[1]Hungry Howie's and Graff's insurers respectivelycould not agree regarding who was responsible for coverage, each contributed $90,000 to the settlement and agreed to determine coverage in a subsequent proceeding.
In 1999, plaintiff filed a complaint for a declaratory judgment that Chrysler was responsible for payment of the entire settlement. Responding to plaintiff's complaint, defendants[2] admitted, in part, that Threehouse was a permissive user of the car at the time the accident occurred. Defendants claimed as their sole affirmative defense that plaintiff's claims were barred by the statute of limitations. Defendants moved for summary disposition, arguing that because Threehouse negligently caused the accident while employed as a Hungry Howie's pizza delivery person, Hungry Howie's and plaintiff were responsible for Threehouse's negligence according to the doctrine of respondeat superior.[3]
Defendants argued in their response brief that because the rental agreement only granted permissive user status while the driver complied with the terms of the lease agreement, when Threehouse violated the agreement by using the car to deliver pizzas, his status as a permissive user immediately ceased. Thus, plaintiff was solely responsible for providing coverage for its insured, Hungry Howie's. At the hearing on the motion for summary disposition, plaintiff countered, in part, *307 that nothing in the lease agreement forbade Threehouse from using the car to deliver pizzas. Plaintiff further stated that the exclusionary language relied on by defendants in the rental agreement only applied to Rahn, not to Threehouse.
In March 2001, the circuit court ruled that the language of the rental agreement made clear that the car was not to be used for delivery purposes. Consequently, the court ruled that Threehouse's violation of the agreement was an absolute defense against any claim filed against either defendant. Summary disposition was granted to defendants for the $90,000 they contributed to the settlement. On rehearing, the court further concluded that defendants were not required to raise the nonpermissive use issue as an affirmative defense in their first responsive pleading, as plaintiff alleged. On November 16, 2001, the court also ordered plaintiff to pay Chrysler interest on the judgment from the final hearing on November 15.[4] Plaintiff appealed, and defendants cross-appealed concerning the award of interest.

II
The first issue is whether Chrysler and Graff are precluded from arguing on appeal that Threehouse was a nonpermissive user of the rental car at the time of the accident because Chrysler and Graff did not raise this issue in their first responsive pleading. We agree with the circuit court that Chrysler's and Graff's argument was properly raised.
This Court reviews de novo a decision on a summary disposition motion. Spiek v. Dep't of Transportation, 456 Mich. 331, 337, 572 N.W.2d 201 (1998). MCR 2.111(F) provides, in relevant part:
(3) Affirmative Defenses. Affirmative defenses must be stated in a party's responsive pleading .... Under a separate and distinct heading, a party must state the facts constituting

* * *
(b) a defense that by reason of other affirmative matter seeks to avoid the legal effect of or defeat the claim of the opposing party, in whole or in part;
(c) a ground of defense that, if not raised in the pleading, would be likely to take the adverse party by surprise.
This Court explained in Stanke v. State Farm Mut. Automobile Ins. Co., 200 Mich.App. 307, 312, 503 N.W.2d 758 (1993), that an affirmative defense is "a matter that accepts the plaintiff's allegation as true and even admits the establishment of the plaintiff's prima facie case, but that denies that the plaintiff is entitled to recover on the claim for some reason not disclosed in the plaintiff's pleadings." (Citation omitted.)
In Stanke, supra at 312-313, 503 N.W.2d 758, this Court held that the issue whether an alleged insured party was operating an "owned" vehicle at the time of an accident was not an affirmative defense. This Court stated that the effect of this claim was to deny that the plaintiff could prove his prima facie case. See id. at 315, 503 N.W.2d 758. The instant case presents a situation very similar to Stanke: Defendants claimed that there was no genuine issue of material fact concerning whether Threehouse was operating the rental car in a manner prohibited by the rental agreement at the time of the accident. Thus, this argument was not subject to the requirement of MCR 2.111(F)(3) *308 that the defense be specifically raised in the first responsive pleading.
Plaintiff also claims that defendants were equitably estopped from claiming that Threehouse's use of the rental car to deliver pizzas was a nonpermissive use because defendants previously admitted that Threehouse was a permissive user of the car at the time of the accident. This Court set forth the elements of equitable estoppel in Cook v. Grand River Hydroelectric Power Co., Inc., 131 Mich.App. 821, 828, 346 N.W.2d 881 (1984):
An estoppel arises where: (1) a party by representation, admissions, or silence, intentionally or negligently induces another party to believe facts; (2) the other party justifiably relies and acts on this belief; and (3) the other party will be prejudiced if the first party is permitted to deny the existence of the facts.
Graff's admissions that Threehouse was a permissive usereven if attributable to Chrysler because Chrysler defended Graffdid not mislead or prejudice plaintiff. See id. Plaintiff, Graff and Chrysler settled the underlying personal injury claim because defendants agreed that liability existed, but disputed between themselves who was responsible for providing coverage. The insured parties were Hungry Howie's and Graff, and neither was prejudiced by Graff's admissions that Threehouse was a permissive user because they agreed to settle the underlying lawsuit and allow their insurance carriers to resolve the coverage dispute between themselves in a declaratory judgment action. Therefore, defendants are not equitably estopped from raising the nonpermissive use defense.[5]

III.
The second issue is whether the phrase in the rental agreement, "to carry passengers or property for consideration express or implied," is ambiguous. We hold that it is not.
Plaintiff maintains that the contract must be interpreted against defendants and that a reasonable interpretation does not support its application to Threehouse's act of using the car to deliver pizzas. The rental agreement Rahn executed listed her fiance, Threehouse, as a person who could be permitted by Rahn to drive the car; that is, he was a permissive user according to the contract.[6] The agreement contained a page of terms and conditions, including the following restriction:
5. The Customer agrees that said Automobile shall not be used or operated:

* * *
i. To carry passengers or property for a consideration, express or implied.
*309 Paragraph 12 of the agreement further provided:
12. If there is any violation of any of the terms, conditions, covenants or restrictions of this agreement by the Customer or by any other driver to whom the Customer has granted permission to operate the Automobile, the rights of the Customer and such other driver to use or operate the Automobile shall terminate immediately, and such violations shall constitute an absolute defense against any claim filed against the Owner or its insurance carrier, and the Customer and such other driver, hereby agree, jointly and severally, to indemnify and save harmless the Owner and its insurance carrier of and from any and all damages, loss, cost and expense that the Owner or its insurance carrier, or both, shall sustain including but not limited to, court costs and counsel fees by reason of any claim for personal injury or property damage. [Emphasis added.]
The rental agreement was a contract between Rahn and Graff, but because it provided insurance coverage, implicating Chrysler's insurance coverage, it was also, in a way, an insurance contract. See, e.g., State Farm Mut. Automobile Ins. Co. v. Enterprise Leasing Co., 452 Mich. 25, 36, 549 N.W.2d 345 (1996) (example of an automobile rental contract providing automobile insurance coverage only for permissive uses).[7] Concerning the interpretation of insurance contractsbut equally applicable to all contractsour Supreme court, in Auto-Owners Ins. Co. v. Churchman, 440 Mich. 560, 566-567, 489 N.W.2d 431 (1992), stated:
An insurance policy is much the same as any other contract. It is an agreement between the parties in which a court will determine what the agreement was and effectuate the intent of the parties. Eghotz v. Creech, 365 Mich. 527, 530, 113 N.W.2d 815 (1962). Accordingly, the court must look at the contract as a whole and give meaning to all terms. Fresard v. Michigan Millers Mut. Ins. Co., 414 Mich. 686, 694, 327 N.W.2d 286 (1982). Further, "[a]ny clause in an insurance policy is valid as long as it is clear, unambiguous and not in contravention of public policy." Raska v. Farm. Bureau Mut. Ins. Co. of Michigan, 412 Mich. 355, 361-362, 314 N.W.2d 440 (1982). This Court cannot create ambiguity where none exists. Edgar's Warehouse, Inc. v. United States Fidelity & Guaranty Co., 375 Mich. 598, 602, 134 N.W.2d 746 (1965).
... [C]overage under a policy is lost if any exclusion within the policy applies to an insured's particular claims. Fresard, supra at 695, 327 N.W.2d 286. Clear and specific exclusions must be given effect. It is impossible to hold an insurance company liable for a risk it did not assume. Kaczmarck v. La Perriere, 337 Mich. 500, 506, 60 N.W.2d 327 (1953).
Threehouse, the permissive user of the car, was involved in an accident while using the car in the course of his employment as a pizza delivery person. The circuit court determined that Threehouse's use of the car to deliver pizzas violated the condition of the rental agreement forbidding "carry[ing] people or property for a consideration, express or implied." After a survey of relevant out-of-state *310 cases, we hold that the better view is that the exclusion precludes coverage in this case.[8]
Plaintiff does not contest that Threehouse used the car to carry propertythe pizzasbut contends that because he was paid a wage for whatever work he did and did not receive a special wage or mileage reimbursement for carrying pizzas, he did not carry property for consideration. We disagree. See Rossow v. Brentwood Farms Dev., Inc., 251 Mich.App. 652, 658, 651 N.W.2d 458 (2002), citing Michigan Nat'l Bank v. Laskowski, 228 Mich.App. 710, 714, 580 N.W.2d 8 (1998) (this Court interprets a contract according to the plain meaning of its terms).
This Court has stated that the term "consideration" has an "ordinary meaning[] [that is] readily and easily understandable to people of ordinary intelligence." People v. Cooper, 166 Mich.App. 638, 652, 421 N.W.2d 177 (1987). In Gen Motors Corp. v. Dep't of Treasury, 466 Mich. 231, 238-239, 644 N.W.2d 734 (2002), our Supreme Court held:
To have consideration there must be a bargained-for exchange. Higgins v. Monroe Evening News, 404 Mich. 1, 20-21, 272 N.W.2d 537 (1978). There must be "`a benefit on one side, or a detriment suffered, or a service done on the other.'" Plastray Corp. v. Cole, 324 Mich. 433, 440, 37 N.W.2d 162 (1949). Courts do not generally inquire into the sufficiency of consideration[.] Harris v. Bond & Mtg. Corp., 329 Mich. 136, 145, 45 N.W.2d 5 (1950). It has been said "[a] cent or a pepper corn, in legal estimation, would constitute a valuable consideration." Whitney v. Stearns, 16 Me. 394 (1839).
Threehouse was employed by Hungry Howie's to make and deliver pizzas. He was paid the minimum wage and was not reimbursed for his mileage, although he did receive tips. In our view, because Threehouse was hired for the purpose of delivering pizzas, his transportation of those pizzas was for consideration. When he borrowed his fiance's car, he did so with the intent to use the car to deliver pizzas so that he could fulfill the conditions of his employment and receive payment in returnif he refused to deliver the pizzas, he would not be paid. He did not simply intend to use the car to drive to work and back.
Moreover, the provision at issue is an appropriate contract exclusion. Graff was renting out a car to Rahn, presumably as a temporary replacement for Rahn's private car. It is reasonable to conclude that a commercial vehicle would command a higher insurance premium because it would likely accumulate more mileage and be used in circumstances more likely to result in accidents. See, e.g., Johnson v. Allstate Ins. Co., 505 So.2d 362, 367 (Ala., 1987); Cartos v. Hartford Accident & Indemnity Co., 160 Va. 505, 516-517, 169 S.E. 594 *311 (1933); Orcutt v. Erie Indemnity Co., 114 Pa.Super. 493, 496, 174 A. 625 (1934).
We conclude that the circuit court correctly ruled that Threehouse's use of the rental car to deliver pizzas triggered the exclusionary provision of the rental agreement, and, because of the exclusion, defendants were relieved of their obligation to provide liability coverage.[9]

IV
Third, we must decide whether the circuit court erred in granting Chrysler's oral motion to file a counterclaim against plaintiff. We hold that the circuit court did not err.
This Court reviews for an abuse of discretion the circuit court's decision to permit a party to amend its pleadings. Weymers v. Khera, 454 Mich. 639, 658, 563 N.W.2d 647 (1997). MCR 2.118(A)(2) provides that a party may amend its pleadings with leave of the court and that leave should be freely given "when justice so requires." In Weymers, supra at 658-660, 563 N.W.2d 647, our Supreme Court stated:
A motion to amend ordinarily should be granted, and should be denied only for the following particularized reasons:
"[1] undue delay, [2] bad faith or dilatory motive on the part of the movant, [3] repeated failure to cure deficiencies by amendments previously allowed, [4] undue prejudice to the opposing party by virtue of allowance of the amendment, [and 5] futility ...." [Ben P. Fyke & Sons v. Gunter Co., 390 Mich. 649, 656, 213 N.W.2d 134 (1973).] ...
Delay, alone, does not warrant denial of a motion to amend. Fyke, supra at 663-664, 213 N.W.2d 134. However, a court may deny a motion to amend if the delay was in bad faith or if the opposing party suffered actual prejudice as a result. Id. "Prejudice" in this context does not mean that the allowance of the proffered amendment may cause the opposing party to ultimately lose on the merits. Id. at 657, 213 N.W.2d 134. Rather, "prejudice" exists if the amendment would prevent the opposing party from receiving a fair trial, if for example, the opposing party would not be *312 able to properly contest the matter raised in the amendment because important witnesses have died or necessary evidence has been destroyed or lost. Id. at 663, 213 N.W.2d 134.... We hold that a trial court may find prejudice when the moving party seeks to add a new claim or a new theory of recovery on the basis of the same set of facts, after discovery is closed, just before trial, and the opposing party shows that he did not have reasonable notice, from any source, that the moving party would rely on the new claim or theory at trial....
Plaintiff argues that the tardy filing of defendants' countercomplaint should have been prohibited because of undue delay and prejudice. However, delay alone is generally not sufficient to warrant denial of a motion to amend, Weymers, supra at 659, 563 N.W.2d 647, and plaintiff has failed to present any evidence of prejudice. Plaintiff argues that discovery was closed, but fails to indicate what further relevant discovery would have been required. Plaintiff claims that the counterclaim advanced a new theory of recovery based on the existing set of facts. However, the counterclaim essentially made the argument that plaintiff was solely responsible for payment of the settlement of the underlying lawsuit and that plaintiff had been aware of that dispute since before the settlement was paid by equal contributions from the disputing insurance companies. With regard to the actual "new" theory of nonpermissive use, the circuit court gave plaintiff ample opportunity to contest that theory on rehearing. Consequently, plaintiff fails to demonstrate that the circuit court abused its discretion by permitting defendants to amend their pleadings by filing a countercomplaint.

V
Finally, Graff and Chrysler crossappeal, raising the following issue: Whether the circuit court erroneously limited Chrysler's recovery of interest under M.C.L. § 600.6013.
Chrysler contends that it is entitled to interest on its payment of $90,000 in settlement of the underlying lawsuit from the date that it paid that sum. Chrysler maintains that prejudgment interest in indemnification cases is awarded from the date the payment is made, rather than the date the complaint is filed. The circuit court disagreed and ruled that the statute provides that interest is calculated from the date the complaint is filed, and, because Chrysler did not file a countercomplaint in response to plaintiff's complaint, interest did not accrue until the date the circuit court denied plaintiff's motion for rehearing.
This Court reviews de novo a circuit court's award of interest pursuant to M.C.L. § 600.6013. Beach v. State Farm Mut. Automobile Ins. Co., 216 Mich.App. 612, 623-624, 550 N.W.2d 580 (1996). Both parties agree that the statutory basis for the payment of prejudgment interest is § 6013, which at the time of the hearing provided, in relevant part:
(1) Interest shall be allowed on a money judgment recovered in a civil action, as provided in this section....

* * *
(5) For complaints filed on or after January 1, 1987, if a judgment is rendered on a written instrument, interest shall be calculated from the date of filing the complaint to the date of satisfaction of the judgment ....
(6) Except as otherwise provided in subsection (5) and subject to subsection (11), for complaints filed on or after January 1, 1987, interest on a money judgment recovered in a civil action shall be calculated ... from the date of filing the complaint ....
*313 This statute provides that in the case of both a judgment on a written instrument and a money judgment, interest is paid from the date of filing the complaint. See also Prestige Cas. Co. v. Michigan Mut. Ins. Co., 969 F.Supp. 1029, 1032 (E.D.Mich., 1997). Thus, we hold that the statutory reference to "the complaint" means the complaint that initiates the legal action between the two partiesin this case, plaintiff's complaint for declaratory judgment. See Wickens v. Oakwood Healthcare Sys., 465 Mich. 53, 60, 631 N.W.2d 686 (2001) ("If the statute's language is clear and unambiguous, we assume that the Legislature intended its plain meaning, and we enforce the statute as written.") (Citation omitted.) Therefore, the circuit court's decision on this issue is reversed. In all other respects, we affirm the court's decision.
Affirmed in part, reversed in part, and remanded for further proceedings consistent with this opinion. We do not retain jurisdiction.
NOTES
[1]  Specifically, Graff's insurance carrier is Chrysler Insurance Company. However, Chrysler Insurance Company is represented in this action by defendant Chrysler Corporation.
[2]  In the court below, plaintiff stipulated the dismissal of defendant Auto Club Insurance Association with prejudice.
[3]  Plaintiff also moved for summary disposition, claiming that both Chrysler's and plaintiff's insurance policies contained an "other insurance" clause that provided that in the case of multiple insurers, each policy would be the primary insurer with respect to an "owned" vehicle, but that with regard to a nonowned vehicle, the policy would provide only excess coverage. Plaintiff asserted that because Graff owned the subject vehicle, its insurerChryslerwas the primary insurer; thus, because Hungry Howie's did not own the vehicle, its insurerplaintiffwas liable only for any excess judgment that was not covered by Graff's policy with Chrysler. However, for reasons we will explain below, there is no excess judgment in the present case.
[4]  Defendants filed a countercomplaint on November 26 specifically requesting reimbursement, because the circuit court ruled at the November 15 hearing that defendants could do so.
[5]  Moreover, as the circuit court ruled, Graff's admission that Threehouse was a permissive user was not inconsistent with defendants' subsequent claim that coverage was excluded because Threehouse's commercial use of the rental vehicle was forbidden by the rental agreement. As we explain more fully below, the rental agreement forbade customers (the renter or a permissive user) from "carry[ing] passengers or property for a consideration...." Threehouse's commercial use of the vehicle to deliver pizzas violated this provision of the agreement and precluded coverage by defendants.
[6]  The rental agreement commenced with the following statement:

In consideration and upon covenants, terms and conditions herein contained, the permissive user as a service customer, hereinafter referred to as "the Customer", rents a temporary substitute automobile that is described in this agreement, hereinafter referred to as "the Automobile", from the owner of the automobile, hereinafter referred to as "the Owner."
[7]  According to the no-fault automobile insurance act, rental car contracts may not completely disclaim insurance coverage for a rental vehicle. See Enterprise Leasing Co., supra at 35-36, 549 N.W.2d 345, cited in Ryder Truck Rental, Inc. v. Auto-Owners Ins. Co., Inc., 235 Mich.App. 411, 414, 597 N.W.2d 560 (1999). The opinion in Ryder Truck Rental, supra, stated that limiting insurance coverage was permissible and distinct from the prohibition on completely excluding coverage of a rental car.
[8]  57 A.L.R. 5th 591, § 2, p. 603, summarizes the states' differing approaches to this issue:

In cases where the facts involve the carrying of property, courts have often considered whether the consideration paid for such transport was an hourly wage or a per-delivery charge. In a number of cases the courts have decided that since the clause was ambiguous as to whether an hourly wage was intended to be covered by the term "fee" or "charge" or "consideration," as used in the clause, then the ambiguity would be resolved in favor of the insured. Other courts have enforced the clause in cases where the property was being transported by an employee receiving an hourly wage, because the courts reasoned that the insurer had not bargained for the risk associated with such a commercial use of a vehicle when writing an automobile policy for personal liability. [Citations omitted.]
[9]  Plaintiff also raises three related claims. First, plaintiff argues that the provisions of the substitute vehicle agreement violate Michigan compulsory lawsthe requirement that a vehicle owner insure the vehicle. See M.C.L. § 257.520(b)(2) (the financial responsibility act, which mandates insurance coverage for permitted drivers of rental cars), and M.C.L. § 257.401(3) (the owner's liability statute, which provides similar coverage for an "authorized" driver or an immediate family member). Because the rental car agreement only disclaimed liability for a specified nonpermissive use and not for all permissive users, the agreement was lawful. See, e.g., Enterprise Leasing Co, supra.

Second, plaintiff now claims on appeal that Threehouse was not a "customer" under the terms of the rental agreement. It does not appear that plaintiff argued this issue below, and this argument is not included in plaintiff's statement of the questions presented. Therefore, it has been waived. McGoldrick v. Holiday Amusements, Inc., 242 Mich.App. 286, 298, 618 N.W.2d 98 (2000), citing City of Lansing v. Hartsuff, 213 Mich.App. 338, 351, 539 N.W.2d 781 (1995), and Meagher v. McNeely & Lincoln, Inc., 212 Mich.App. 154, 156, 536 N.W.2d 851 (1995).
Third, plaintiff contends that the policy of insurance issued by Chrysler provides primary coverage for the accident. Because we hold that the circuit court correctly ruled that Threehouse's violation of the exclusionary clause in the rental agreement rendered the agreement void and relieved Chrysler of its duty to provide coverage, it was plaintiff's duty to provide primary coverage for Hungry Howie's employees. See, e.g., Enterprise Leasing Co., supra. As a consequence of the fact that Chrysler's policy exceeded the settlement amount, there is no excess judgment amount and Chrysler is responsible for the entire settlement.
