OPINION
HOLLIS HORTON, Justice.

I. Introduction
This is an appeal from a summary judgment rendered in favor of appellees Fire Insurance Exchange (hereafter "FIE") and Texas Farmers Insurance (hereafter "TFI"). In a single issue, appellants Shannon Trahan and Joleen Trahan Woods[1] (hereafter "the Trahans") complain the trial court erred in granting summary judgment because there are genuine issues of material fact. We affirm the summary judgment.

II. Factual Background
On December 31, 2000, the Trahans' home and automobile were destroyed by a fire. The Trahans filed a fire loss claim with FIE under their homeowner's policy, and a claim with TFI under their automobile policy. On or about February 8, 2001, the Trahans signed a Proof of Loss form and sent the form to FIE. On February 14, 2001, FIE requested that the Trahans submit to examinations under oath ("EUOs"). The Trahans did not respond to the February 14 request or most of FIE's subsequent requests. On August 29, 2001, the Trahans submitted to the EUOs, and they signed and swore to the transcripts on September 20, 2001. On October 8, 2001, FIE accepted the Trahans' fire loss claim and issued checks for the claim.
The Trahans brought suit against FIE and TFI alleging breach of contract, breach of the common law duty of good faith and fair dealing, violations of the Insurance Code, and violations of the Deceptive Trade Practices Act. The Trahans alleged that FIE and TFI violated contractual obligations and committed bad faith by delaying payment and destroying physical evidence.
FIE filed a traditional motion for summary judgment and a no-evidence motion for summary judgment. See TEX.R. CIV. P. 166a(c), 166a(i). In the traditional motion for summary judgment, FIE asserted that the Trahans failed to meet the conditions precedent to recovering on their homeowner's claim, it did not breach the insurance contract, and there is no extra-contractual liability when there is no breach of contract. In the no-evidence motion for summary judgment, FIE asserted, inter alia, that there was no evidence that it failed to make timely payments or violated any contractual obligations or duties. TFI filed a single motion asserting both no-evidence and traditional grounds for summary judgment. See id. In the motion, TFI asserted, inter alia, that there was no evidence that it assumed any risk of loss for the Trahans' home and there was no privity of contract between TFI and the Trahans regarding the homeowner's claim.
In response to FIE's and TFI's motions for summary judgment, the Trahans asserted that FIE and TFI committed bad faith by performing an "outcome oriented *672 or biased investigation in an attempt to prove that [they] destroyed their home by incendiary fire." The Trahans also alleged that FIE and TFI committed spoliation. The trial court granted FIE's and TFI's motions for summary judgment and ordered that the Trahans take nothing.[2] The Trahans appealed.

III. Standard of Review
We review a trial court's order granting summary judgment de novo. Provident Life & Accident Ins. Co. v. Knott, 128 S.W.3d 211, 215 (Tex.2003). We apply different standards of review to the motions for summary judgment filed under Rule 166a(c) and the motions filed under Rule 166a(i).
To succeed in a motion for summary judgment under Rule 166a(c), a movant must establish that there is no genuine issue of material fact so that the movant is entitled to judgment as a matter of law. Lear Siegler, Inc. v. Perez, 819 S.W.2d 470, 471 (Tex.1991). In reviewing a summary judgment, we consider the evidence in the light most favorable to the non-movant and resolve any doubt in the non-movant's favor. Nixon v. Mr. Property Mgmt. Co., 690 S.W.2d 546, 548-49 (Tex.1985). Under Rule 166a(i), a party may move for summary judgment on the ground that there is no evidence of one or more essential elements of a claim or defense on which an adverse party would have the burden of proof at trial. Unless the respondent produces summary judgment evidence raising a genuine issue of material fact, the court must grant the motion. Tex.R. Civ. P. 166a(i); Johnson v. Brewer & Pritchard, P.C., 73 S.W.3d 193, 207 (Tex.2002).
Western Invs., Inc. v. Urena, 162 S.W.3d 547, 550 (Tex.2005). Because the trial court did not state the grounds for granting summary judgment, we will uphold the summary judgment if it can be sustained under either traditional or no-evidence grounds. Dow Chem. Co. v. Francis, 46 S.W.3d 237, 242 (Tex.2001).
We first address whether summary judgment may be upheld in favor of FIE on traditional grounds. A defendant who disproves an essential element of the plaintiff's cause of action as a matter of law is entitled to summary judgment. Doe v. Boys Clubs of Greater Dallas, Inc., 907 S.W.2d 472, 476-77 (Tex.1995). "After the defendant produces evidence entitling it to summary judgment, the burden shifts to the plaintiff to present evidence creating a fact issue." Walker v. Harris, 924 S.W.2d 375, 377 (Tex.1996).

IV. Summary Judgment Analysis  FIE

A. FIE's Request for EUOs
FIE's summary judgment proof demonstrated that it had a contract with the Trahans, and that it paid the Trahans' claim under the terms and conditions of the policy. The Trahans' homeowner's insurance policy includes the following paragraphs:
AGREEMENT
We will provide the insurance described in this policy in return for the premium *673 and compliance with all applicable provisions of this policy.
SECTION I  CONDITIONS
3. Duties After Loss.
a. Your Duties After Loss. In case of a loss to covered property caused by a peril insured against, you must:
...
(5) as often as we reasonably require:
...
(b) provide us with pertinent records and documents we request and permit us to make copies.
(c) submit to examination under oath and sign and swear to it.
...
b. Our Duties After Loss.
(1) Within 15 days after we receive your written notice of claim, we must:
(a) acknowledge receipt of the claim.
If our acknowledgment of the claim is not in writing, we will keep a record of the date, method and content of our acknowledgment.
(b) begin any investigation of the claim.
(c) specify the information you must provide in accordance with "Your Duties After Loss[.]"
We may request more information, if during the investigation of the claim such additional information is necessary.
(2) After we receive the information we request, we must notify you in writing whether the claim will be paid or has been denied or whether more information is needed:
(a) within 15 business days; or
(b) within 30 days if we have reason to believe the loss resulted from arson.
(3) If we do not approve payment of your claim or require more time for processing your claim, we must:
(a) give the reason for denying your claim; or
(b) give the reasons we require more time to process your claim.
But, we must either approve or deny your claim within 45 days after requesting more time.
The Trahans first claim that FIE relied on the affirmative defense of arson and FIE failed to prove that the fire was of an incendiary origin. As a result, the Trahans argue, FIE's request that they submit to EUOs was not justified because FIE's investigation provided sufficient evidence that the Trahans did not commit arson.
The conditions under which an insurance company may conduct an EUO are governed by the insurance contract. See State Farm Gen. Ins. Co. v. Lawlis, 773 S.W.2d 948, 949 (Tex.App.-Beaumont 1989, no writ). When we interpret an insurance policy, we employ the rules of contract construction. American Mfrs. Mut. Ins. Co. v. Schaefer, 124 S.W.3d 154, 157 (Tex.2003). "If policy language is worded so that it can be given a definite or certain legal meaning, it is not ambiguous and we construe it as a matter of law." Id. If a contract is not ambiguous, the words used in the contract are to be given their ordinary meaning. Puckett v. U.S. Fire Ins. Co., 678 S.W.2d 936, 938 (Tex. 1984). For an event to constitute a "condition precedent" under a contract, the contract must provide that the event "must happen or be performed before a right can accrue to enforce an obligation." Centex Corp. v. Dalton, 840 S.W.2d 952, 956 (Tex.1992).
*674 Contrary to the Trahans' assertion, a review of the record reveals that FIE did not plead, nor argue, arson as an affirmative defense. To prevail on summary judgment, a defendant must plead and conclusively establish each element of an affirmative defense. See City of Houston v. Clear Creek Basin Auth., 589 S.W.2d 671, 678 (Tex.1979); TX. R. CIV. P. 94. However, because FIE did not plead arson as an affirmative defense, FIE did not have to prove that the fire was of an incendiary origin. See Clear Creek Basin Auth., 589 S.W.2d at 678; TEX.R. CIV. P. 94; State Farm Fire & Cas. Co. v. Simmons, 963 S.W.2d 42, 45 n. 1 (Tex.1998) ("Arson is an affirmative defense to an insurance claim for a loss resulting from a fire.").
The policy at issue imposes a duty upon the Trahans to "submit to examination under oath and sign and swear to it" upon request. Insurance policy provisions requiring an insured to submit to an EUO as a condition precedent are valid. Lawlis, 773 S.W.2d at 949. FIE's February 14 letter requesting that the Trahans submit to EUOs included a paragraph that provided FIE did not "waive any of its rights under the policy and hereby reserves each and all of its rights under the policy."
The language of the insurance policy does not support the Trahans' position that FIE must justify a request for EUOs with evidence supporting a reasonable suspicion of arson. The language of the policy does not require that FIE suspect arson before requiring the Trahans to submit to EUOs.
The Trahans also argue that FIE's right to request the EUOs was voided because the EUOs were used in an attempt to convince the Trahans to "agree to a lesser settlement or drop their claim entirely." The Trahans presented no summary judgment evidence showing that FIE used the EUOs in this manner. Furthermore, the Trahans cite no case law that limits FIE's right to obtain EUOs under the insurance contract. The Trahans did not satisfy their burden to produce summary judgment evidence sufficient to raise a fact issue. See TEX.R. CIV. P. 166a(c).

B. Breach of the Duty of Good Faith and Fair Dealing
The Trahans also argue that FIE breached the duty of good faith and fair dealing when it delayed in requesting the EUOs, delayed in paying the loss claims, and conducted the loss investigation in bad faith. An insurer has a duty of good faith and fair dealing in the processing and payment of claims. Republic Ins. Co. v. Stoker, 903 S.W.2d 338, 340 (Tex.1995). A cause of action for breach of the duty of good faith and fair dealing is established when an insurer knew or should have known it had no reasonable basis for denying or delaying payment of a claim. Id.

i. Breach of Contract
While insurance coverage claims and bad faith claims are by their nature independent, in most circumstances an insured may not prevail on a bad faith claim without first prevailing on a breach of contract claim. Liberty Nat. Fire Ins. Co. v. Akin, 927 S.W.2d 627, 629 (Tex. 1996). See also Perrotta v. Farmers Ins. Exch., 47 S.W.3d 569, 575 (Tex.App.Houston [1st Dist.] 2001, no pet.) ("When the underlying claim upon which an insured's extra-contractual claims are premised is found to have been properly denied, ... [the] extra-contractual claims necessarily fail."). The elements of a breach of contract cause of action are the existence of a valid contract, the plaintiff's performance or tendered performance, the defendant's breach of the contract, and damages as a result of the breach. Sullivan v. Smith, *675 110 S.W.3d 545, 546 (Tex.App.-Beaumont 2003, no pet.).
The insurance policy imposes a duty upon FIE to investigate the loss claim within fifteen days after receiving a written notice of claim and to accept or deny the claim within fifteen business days of receiving all of the information requested during the investigation. The record indicates that FIE received written notice of the claim on February 8. The record also indicates that on February 14, FIE requested additional information from the Trahans in the form of EUOs. The request was provided within the time period allowed under the policy. The EUOs were not taken until August 29, and they were not sworn to and signed until September 20. The loss claim was paid on October 8, which was within fifteen business days of the signing and swearing of the EUOs.
The EUOs were the last items of information requested. FIE paid the claim within fifteen business days of receiving the sworn EUOs, FIE satisfied the provisions of the contract. Because FIE's payment was timely under the insurance contract, FIE did not breach the duty of good faith and fair dealing. See Akin, 927 S.W.2d at 629; see also Perrotta, 47 S.W.3d at 575. Because FIE disproved the breach of contract element of the Trahans' claim, the trial court properly granted FIE's traditional motion for summary judgment. See Boys Clubs, 907 S.W.2d at 476-77.

ii. Spoliation
The Trahans also assert that FIE committed spoliation of evidence favorable to them. Armstrong Forensic Laboratory examined samples of fire debris collected from the Trahans' home and reported that the samples tested "negative for identifiable ignitable liquids." The laboratory destroyed the samples when its fee to store the samples was not paid. The Trahans argue that the samples were the best evidence that they did not commit arson and that it was bad faith to destroy them. However, FIE did not assert arson as a basis for denying the Trahans' claim.
The primary issue in this bad faith claim is whether FIE had no reasonable basis to delay payment. See Stoker, 903 S.W.2d at 340. The Trahans presented no summary judgment evidence establishing that FIE destroyed the samples as a basis for delaying or denying payment or that the claim would have been paid sooner had the samples not been destroyed. See id. As a result, the Trahans have not shown that the samples were destroyed in bad faith. Therefore, the Trahans' spoliation argument fails to raise a genuine issue of material fact.

V. Summary Judgment Analysis  TFI
We next address whether summary judgment in favor of TFI may be upheld on no-evidence grounds. To defeat a no-evidence summary judgment motion, the nonmovant is required to produce summary judgment evidence raising a genuine issue of material fact. Fort Worth Osteopathic Hosp., Inc. v. Reese, 148 S.W.3d 94, 99 (Tex.2004); TEX.R. CIV. P. 166a(i). The nonmovant raises a genuine issue of material fact by producing more than a scintilla of evidence establishing the challenged element's existence. Reese, 148 S.W.3d at 99.
The Trahans' suit against TFI asserts TFI and FIE were jointly liable under the homeowner's policy issued by FIE. The Trahans asserted FIE investigated the claim on behalf of TFI; FIE and TFI shared the risk of loss for the claim; and TFI conspired with FIE to investigate the claim in bad faith. TFI filed a hybrid motion for summary judgment asserting the Trahans had no evidence of joint liability.
*676 The record does not indicate the Trahans provided evidence or otherwise addressed the grounds asserted in TFI's no-evidence motion for summary judgment. Accordingly, we find the Trahans did not carry their burden to provide evidence in support of their claims against TFI. See id. In the absence of a fact issue to be resolved by a jury, TFI was entitled to summary judgment under Rule 166a(i). See id.; TEX.R. CIV. P. 166a(i). The Trahans' sole issue is overruled, and the judgment of the trial court is affirmed.
AFFIRMED.
NOTES
[1]  Woods's first name appears in the record as both "Joleen" and "Jolene." To be consistent with the insurance policy, we use "Joleen." Woods's last name appears in the record as "Trahan" and "Woods." To be consistent with the notice of appeal, we use "Woods."
[2]  The trial court sent the parties a letter explaining its grounds for granting the motions for summary judgment. The Trahans' brief appears to challenge the grounds asserted in the letter. We do not consider the letter as conclusive on the bases for the trial court's ruling because a letter cannot be considered on appeal as giving the comprehensive reasons that a trial court granted summary judgment. See Sharpe v. Roman Catholic Diocese of Dallas, 97 S.W.3d 791, 796 (Tex.App.-Dallas 2003, pet denied); Strather v. Dolgencorp of Texas, Inc., 96 S.W.3d 420, 423 (Tex.App.-Texarkana 2002, no pet.).
