This insurance-coverage dispute involves the interpretation of an “advertising inju *546 ry” clause in a commercial general liability policy. Websolv Computing, Inc., was sued in Illinois state court for sending an unsolicited fax advertisement to a dental office. Websolv tendered the defense of this suit to its insurer, Auto-Owners Insurance Company, which accepted it under a reservation of rights. Auto-Owners then filed this action in federal court seeking a declaratory judgment that it had no duty to defend Websolv in the underlying Illinois suit. The district court applied Illinois law and held that Websolv’s policy with Auto-Owners covered the claim. We reverse. Iowa law — not Illinois law — applies here. Under Iowa law the insurance policy does not require Auto-Owners to defend Websolv in the underlying suit.
I. Background
In September 2003 Guy Bibbs sued Websolv in Illinois state court for sending an unsolicited one-page fax advertisement to his dental office. Bibbs claimed, among other things, that Websolv violated the Telephone Consumer Protection Act (“TCPA”), 47 U.S.C. § 227. 1 The fax at issue was an advertisement for seminars to train health-care professionals how to comply with the terms of the Health Insurance Portability and Accountability Act. The parties later agreed to substitute Gortho, Ltd., Bibbs’s dental practice, as the plaintiff, and the state court dismissed with prejudice all claims related to Bibbs. Websolv was insured by Auto-Owners under a commercial general liability (“CGL”) policy and tendered its defense to the insurer. Auto-Owners accepted the tender, appointed counsel, and reserved its right to argue that it had no duty to defend Websolv under the terms of the policy.
Auto-Owners then filed this action in federal court seeking a declaration that it had no duty to defend Websolv. The parties agreed that Iowa law should control and filed cross-motions for summary judgment. Despite the parties’ stipulation to Iowa law, the district court concluded that Illinois law governed. It granted Websolv’s motion for summary judgment, holding that under Illinois law the insurance contract required Auto-Owners to defend the type of claims at issue here. It based its decision on the Illinois Supreme Court’s opinion in
Valley Forge Insurance Co. v. Swiderski Electronics, Inc.,
II. Discussion A. Choice of Law
We begin by addressing the district court’s decision to apply Illinois law rather than Iowa law to this dispute. We review a district court’s choice-of-law decision de novo.
Gramercy Mills, Inc. v. Wolens,
First, and most importantly, the parties agreed that Iowa law should con
*547
trol their dispute. We honor reasonable choice-of-law stipulations in contract cases regardless of whether such stipulations were made formally or informally, in writing or orally.
Lloyd v. Loeffler,
Indeed, Websolv has never objected to the application of Iowa law — either in the district court or on appeal. In its brief on appeal, Websolv explicitly stated it “does not disagree that Iowa law governs.” Rather, Websolv has argued that Iowa courts would adopt the same interpretation of the policy language as the Illinois Supreme Court did in Valley Forge. This is an argument over the content, not the applicability, of Iowa law. Because the parties agreed that Iowa law should govern and because the choice of Iowa law is entirely reasonable, the district court should not have applied Illinois law.
The district court also was mistaken in its belief that it had to apply the substantive law of the forum state. When a federal court hears a case in diversity, it does not necessarily apply the substantive law of the forum state; rather, it applies the choice-of-law rules of the forum state to determine which state’s substantive law applies.
Klaxon Co. v. Stentor Elec. Mfg. Co.,
313
U.S.
487, 496,
Finally, the district court believed it could apply Illinois law because neither party had briefed the court on the substance of Iowa law. The court cited
Employers Mutual Casualty Co. v. Skoutaris,
In any event, the parties did brief the court on the substance of Iowa law. After *548 agreeing that Iowa law applied, Auto-Owners specifically requested permission to file a supplemental memorandum in support of its motion for summary judgment addressing the substance of Iowa law. Instead of granting Auto-Owners’ motion, the district court instructed the briefing to continue as scheduled. In its response to Auto-Owners’ summary-judgment motion, Websolv explained that there was no controlling Iowa law but argued that Iowa shared the same basic contract principles as Illinois, which had a deci sion' — Valley Forge — directly on point. Auto-Owners then filed a reply discussing why Iowa contract-law principles would lead Iowa to a different result from that reached in Illinois. 2
B. Does the Insurance Policy Cover Gortho’s Claims?
Our next question is whether, under Iowa law, the terms of the CGL policy require Auto-Owners to defend Websolv against Gortho’s claims. Gortho’s primary claim against Websolv is that it violated the TCPA by faxing an unsolicited, one-page advertisement to Gortho. The TCPA prohibits the use of “any telephone facsimile machine, computer, or other device to send, to a telephone facsimile machine, an unsolicited advertisement.” 47 U.S.C. § 227(b)(1)(C). It also permits persons or entities to sue in state court for violations of the TCPA and to recover between $500 and $1,500 in damages for each violation. Id. Websolv argues that Auto-Owners is required to defend it from Gortho’s claims under two separate provisions in the policy — the “advertising injury” provision and the “property damage” provision.
1. “Advertising Injury” Coverage
The insurance policy specifically requires Auto-Owners to defend against suits alleging “ ‘advertising injury’ caused by an offense committed in the course of advertising [the insured’s] goods, products or services.” The contract then defines “advertising injury” as follows:
“Advertising injury” means injury arising out of one or more of the following offenses:
a. Oral or written publication of material that slanders or libels a person or organization or disparages a person’s or organization’s goods, products or services;
b. Oral or written publication of material that violates a person’s right of privacy;
c. Misappropriation of advertising ideas or style of doing business; or
d. Infringement of copyright, title or slogan.
Websolv contends that the language in subsection (b) triggers Auto-Owners’ duty to defend the TCPA claim. In response Auto-Owners claims that the right of privacy referred to in subsection *549 (b) only covers secrecy-based privacy interests rather than seclusion-based privacy interests and that a TCPA suit asserts an invasion of a seclusion-based interest. While Iowa has no caselaw precisely on point, 3 we conclude that it would more likely accept the interpretation that Auto-Owners advances.
The insurance policy does not define the “right of privacy,” and that phrase can have multiple meanings and refer to a variety of rights. The
Restatement (Second) of Torts
identifies four ways in which one’s right of privacy can be invaded: (1) unreasonable intrusion upon another’s seclusion; (2) appropriation of another’s name or likeness; (3) unreasonable publicity given to another’s private life; and (4) publicity that places another in a false light. § 652A(2). We have previously organized these rights into two broad categories — rights involving secrecy interests and rights involving seclusion interests.
Am. States Ins. Co. v. Capital Assocs. of Jackson County, Inc.,
The underlying suit here only involves seclusion interests. Gortho does not contend that Websolv’s fax advertisement revealed secret or proprietary information about it; rather, it alleges that the unsolicited fax intruded on its right to be left alone. 4 Therefore, the question in this case is whether the “advertising injury” coverage in the CGL policy requires Auto-Owners to defend Websolv in a suit claiming an infringement of Gortho’s seclusion interests.
As we have noted, Iowa has no precedent on this exact question.
5
Instead, the
*550
parties offer only general principles of insurance-contract interpretation culled from Iowa cases, which are too generic to be of much help. However, this is not the first time that we have been asked to interpret this particular policy language without the benefit of a state high-court decision on point. In
American States Insurance Co. v. Capital Associates,
we were faced with this same “advertising injury” question under Illinois law.
Two years later, the Illinois Supreme Court had the opportunity to decide the issue. It disagreed with our analysis in
American States
and held instead that under Illinois law advertising-injury policy provisions cover TCPA claims.
Valley Forge Ins. Co. v. Swiderski Elecs., Inc.,
We are now faced with this question a second time, but under Iowa law rather than Illinois law. We stand by our analysis in
American States,
even though Illinois has since adopted a different approach. We conclude that Iowa is more likely to adopt our interpretation rather than the one adopted by the Illinois Supreme Court. It is true that Iowa, like Illinois, gives undefined words in an insurance contract their ordinary meaning.
A.Y. McDonald Indus., Inc. v. Ins. Co. of N. Am.,
“Publication” is implicated only where the relevant concern is secrecy; one can violate another’s right to seclusion without publicizing anything.
See, e.g., Doe v. Mills,
The other subsections of the definition of “advertising injury” also support this interpretation. The other three provisions of the advertising-injury definition focus on harm arising from the content of an advertisement rather than harm arising from mere receipt of an advertisement. The surrounding provisions cover advertising-injury claims for libel, slander, misappropriation, and copyright infringement— all of which require the examination of the content of the offending advertisement. 6 It is therefore reasonable to infer that subsection (b) also concerns harm emanating from the content of an advertisement; that is, it is reasonable to read subsection (b) to refer only to violations of secrecy interests. Here, Gortho is not complaining about the content of the fax; rather, it complains that the very fact the fax was sent violated the corporation’s right to be left alone under the TCPA. Accordingly, we conclude that the advertising-injury provision does not cover claims brought under the TCPA.
2. Property-Damage Provision
Under the CGL policy, Auto-Owners also has a duty to defend its insured against claims arising from property damage, defined as “physical injury to tangible property.” However, the policy specifically excludes property damage that is expected or intended from the standpoint of the insured. Websolv argues that Gortho’s claim is a claim for property damage because the unsolicited fax advertisement used ink and paper from Gortho’s fax machine. While it is true that the one-page fax advertisement consumed a small amount of ink and one sheet of paper from Gortho’s machine, this consequence was both expected and intended by Websolv. Because the policy expressly excludes damage that is expected or intended by the insured, Auto-Owners has no duty to defend Websolv under this provision.
See Resource Bankshares Corp. v. St. Paul Mercury Ins. Co.,
*552 Websolv attempts to evade this fairly obvious conclusion by arguing that the policy’s “separation of insureds” provision requires us to evaluate the property damage from the perspective of the company separately from the perspective of the employee who actually sent the fax. In other words, Websolv contends that while the fax-sending employee may have intended to use up Gortho’s toner and paper, Websolv itself intended no such thing, and therefore it did not expect or intend the resulting property damage. The primary problem with this argument is that Gortho’s complaint in the underlying case alleges that Websolv sent the fax and that Pabrai (the individual defendant in the case) merely “authorized and approved” it. Accordingly, the “separation of insureds” provision does not help Websolv.
For the foregoing reasons, we Reverse the decision of the district court and Remand with instructions to enter summary judgment in favor of Auto-Owners.
Notes
. Bibbs also sued Uday Om Ali Pabrai and John Does 1 through 10. Bibbs alleged violations of the TCPA and the Illinois Consumer Fraud Act, 815 III. Comp. Stat. § 505/2, as well as claims for common-law conversion and "property damage.”
. Websolv makes a related argument that Auto-Owners failed to show that Iowa law differed from Illinois law in any material respect. It cites Illinois cases purportedly standing for the rule that Illinois courts presume the law of the governing jurisdiction is the same as Illinois unless the party shows a material difference between the two. The cases Websolv cites, however, appear to be based on waiver; in those cases the parties did not cite to
any
authority from the purportedly applicable jurisdiction. Here, on the other hand, the parties agreed that there is no Iowa case directly on point. Without recourse to specific Iowa caselaw, Auto-Owners argued from general principles of Iowa insurance law (for which it cited to Iowa cases), as well as caselaw from other jurisdictions. We do not think Illinois requires any more from litigants.
See Sterling Fin. Mgmt. v. UBS PaineWebber, Inc.,
. Because Iowa has no pertinent caselaw on this question, Gortho asks us to certify this issue to the Iowa Supreme Court. Certification is appropriate only when " 'the case concerns a matter of vital public concern, where the issue will likely recur in other cases, where resolution of the question to be certified is outcome determinative of the case, and where the state supreme court has yet to have an opportunity to [decide] ... the issue.'
State Farm Mut. Auto. Ins. Co. v. Pate,
. Gortho, as a corporation, does not have any common-law seclusion rights. See Restatement (Second) of Torts § 6521 cmt. c (“A corporation, partnership or unincorporated association has no personal right of privacy. It has therefore no cause of action for any of the four forms of invasion covered by [§ 652B].”). Any seclusion interests it asserts derive from the TCPA, not common law.
. In 2007 a district court in this circuit attempted to answer this question under Iowa law and concluded that the advertising-injury provision covered TCPA claims.
Am. Home Assurance Co. v. McLeod USA, Inc.,
. Auto-Owners also argues that the phrase "right of privacy” refers only to Iowa's state-law tort of invasion of privacy and does not include violations of federal law like the TCPA, which protects similar interests. As support it argues that the surrounding provisions all refer to specific state-law torts. Given our conclusion, we need not address this alternative argument. We note, however, that subsection (d) refers to copyright infringement, which arises under federal law rather than state common law. Therefore, it is not unreasonable to assume that the phrase "right of privacy” encompasses rights arising under federal law as well as state tort law.
