OPINION
EASTAUGH, Justice.
I. INTRODUCTION
Juneau resident Karen Carpenter wrote a letter to a Juneau radio station complaining about the Tom Leykis Show, a national radio talk show broadcast locally by the station. The station forwarded her letter to Tom Leykis, who read it on the air while making derogatory and sexually explicit remarks about Carpenter and making other comments that allegedly inflamed listeners and encouraged them to contact or confront Carpenter. Carpenter sued Leykis and his producer, Westwood One, for defamation, intentional and negligent infliction of emotional distress, and invasion of privacy. She also sued for spoliation of evidence, claiming Westwood One and Leykis intentionally destroyed the tape of part of the show. The superior court granted summary judgment against Carpenter on her defamation, negligent infliction of emotional distress, and false light privacy claims, but submitted her spoliation, intentional infliction of emotional distress (IED), and "intrusion upon seclusion" claims to a jury. The jury found for Leykis and West-wood One on the IIED and intrusion claims and found for Carpenter against Westwood One on the spoliation claim and awarded her compensatory and punitive damages against Westwood One. The parties appeal rulings concerning the defamation, privacy, and IIED claims. Westwood One challenges the spoliation verdict and the damage awards. Carpenter disputes the constitutionality of allocating part of the punitive damages award to the State of Alaska, and she and the state raise questions about how that allocation should have been calculated. We reverse in part and remand because we conclude that Instruction No. 17 erroneously limited the jury's consideration of Carpenter's IIED claim. With a minor exception relating to costs, we otherwise affirm the superior court's rulings.
II. FACTS AND PROCEEDINGS
Tom Leykis is a "radio personality"; in 1998 he hosted the Tom Leykis Show, a four-hour radio talk show. Sex-related topics were a common feature of the program. Westwood One, Inc. produced and distributed the show as a live radio program broadcast five days a week by radio stations nationwide. Juneau AM radio station KJNO broadcast the show weekdays from two to six p.m. in the Juneau area between June 8 and July 24, 1998.
[48] Karen Carpenter, a Juneau resident, first heard the show on July 20, 1998. Carpenter testified at trial that she was concerned about its content, and expressed her concerns to a City and Borough of Juneau assembly member on July 21 and also made or tried to make various inquiries to other government officials asking about decency laws. Carpenter testified that she contacted "three or four" KJNO advertisers on July 22 and asked them if they knew their ads. were being run during the Tom Leykis Show and whether they wanted their advertising dollars to support the content of the show. Carpenter then faxed KJNO a letter stating that she found "the majority" of the show "very offensive" and that she thought it was unsuitable to air when children might be listening. Her letter informed KJNO that she had contacted and would continue to contact Juneau radio advertisers whose ads ran during the Tom Leykis Show and that she would "do everything in [her] power to have the show taken off the air as soon as possible." The station placed the letter, which displayed Carpenter's fax number, in its "public file." Someone at KINO faxed a copy of the letter to the Tom Leykis Show in California with a handwritten note, "Have fun." Carpenter testified that she was unaware that, as required by federal regulations, the letter would be placed in the station's public file.1
Around that time, Steve Rhyner, KJNO's station manager, decided to take the Tom Leykis Show off the air because major advertisers had complained about the program and Rhyner objected to the content of one particular show. July 24, 1998 was the last day the Tom Leykis Show was broadcast in Juneau.
During the July 24 broadcast, Leykis made several remarks about KJNO's cancellation of the show and Carpenter's letter. He de-seribed those who objected to the show as "some small band of old prunes and old blue-hairs, nut cases and all these cretins." He said: "[Alfter we go, keep an eye on our web site. I'm going to find out who these people are [who cancelled the show], and we'll put it up on the web site." He complained "I hate those-those old biddies who sit out there and have nothing better to do than to write in to radio stations." He also said: "Maybe if this woman had gotten laid in the last 50 years, who writes into the station and started making all these waves, maybe she wouldn't be complaining so much. I'm not kidding." After reading Carpenter's letter on the air, Leykis commented:
And it's signed, the woman who wrote the letter-it's signed: Karen Carpenter. Well Karen, I have a little something that you could use right about now. [buzzing sound intended to simulate the sound of a vibrator]
Sit on this, you old prune. Come on, get close to the radio. Get right on top of the speaker, baby. You moron. You jerk. You and your little band of nut cases out there, trying to decide what's going to be on the radio in Juneau, Alaska. You know, maybe you ought to go out and get laid once in awhile, huh? [buzzing sound]
You eretin. Are your nipples getting hard yet, baby? Feel the power. You can't stop this show. Oh, you can stop Juneau, Alaska. But you can't stop me....
You and your stupid-your stupid church and your stupid religion, and you and your stupid god damned bunch of marauders. You morons. Jerks.
I'm enjoying this. I'm sporting wood right now, just thinking about it. Woo hoo....

Oh, Karen Carpenter. Karen Carpenter wanted our show off the air. No, not that Karen Carpenter. But Karen, sit on it, baby. [buzzing sound]
[49] Oh, yeah. See, if you got more of this, you wouldn't be writing complaint letters to the station.
Later in the show, a Juneau caller attempted to broadcast Carpenter's home telephone and fax numbers, which were listed in the local telephone directory under "KL. Carpenter," and expressed the hope that people would "send her faxes." The telephone number was partially bleeped out. Around this time, according to the trial testimony of one of Carpenter's friends, Leykis also encouraged his listeners to make Carpenter's telephone "ring off the hook." Later in the program a Juneau fan called in to praise the show. Leykis responded: "Well, we hate to lose you, but like I say, stay tuned, 'cause we're going to get back on in Juneau.... And we're going to make that woman's life a living hell." According to the trial testimony of another of Carpenter's friends, this "living hell" comment was "used repeatedly throughout the broadcast."
Carpenter heard the first part of the broadcast and learned about other parts of the show from friends who had heard it. She testified later that she felt humiliated and sexually violated. She testified that she received a telephone message at her home that repeated part of what Leykis had said about her. She also received several "threatening" faxes at her home. Carpenter was later diagnosed with post-traumatic stress syndrome and an anxiety disorder.
The Tom Leykis Show was recorded in the studio on VHS videotapes as the show aired. These tapes were stored in a drawer in the studio; as soon as the drawer was full, the tapes were recycled, erasing the recordings. There were various estimates of how long the tapes stayed in the drawer. A Westwood One executive estimated they stayed there four to six months, while the show's producer testified that "judging by the size of the drawer, [the tapes] go back six to eight months, or approximately a year."
Carpenter wrote in an affidavit that she "believe[d]" she requested a copy of the July 24, 1998 tape from Westwood One and never received a response, and at trial she testified with certainty to having requested a copy. She also made several requests through her lawyers. Attorney Robert Reges testified that he sent an email to KJNO requesting a tape "soon after" the July 24 broadcast. An affidavit from KJNO employee Justin McDonald indicates that Reges did not identify himself as a lawyer, and did not admit the true purpose of his request.
On December 24, 1998, five months after the broadcast, another Carpenter attorney, Jim Douglas, wrote a letter to KJNO and Westwood One, requesting a tape and making it clear that legal action might be forthcoming. No address was given for West-wood One, just the name of the company and its street address in California. Westwood One employees testified that they had not seen the letter, but the show's producer testified to a general recollection that the company's legal department had requested the tape and that upon receiving such a request he would have made a copy of the tape and sent it to the legal department. He recalled that a copy "was found." He also testified that he "would not intentionally have altered or destroyed a tape of thle] show, and that he did not do so." Douglas testified that he never received a response from Westwood One, and that KJNO told him that the station had forwarded the letter to Westwood One. The only copy of the July 24 show ever found was a cassette of the first two hours; KJNO's Justin McDonald provided this tape and recalled in an affidavit that Westwood One had sent him the tape "possibly before the end of 1998." He kept the cassette with his personal tapes and forgot about it until Steve Rhyner requested it in 2001. There was no evidence that a recording of the second half of the four-hour show ever surfaced.
Carpenter filed a superior court complaint against Tom Leykis, Westwood One, KJNO, Alaska Broadcast Communications, Inc., and Steve Rhyner. She alleged that Leykis's comments about her on his July 24, 1998 broadcast were defamatory, caused negligent and intentional infliction of emotional distress, and placed her in a false light. She also alleged that Leykis and Westwood One spoliated evidence.
Alaska Broadcast Communications, West-wood One, and Leykis filed summary judgment motions on all of Carpenter's claims on [50] grounds that Leykis's comments were protected by the First Amendment and that Carpenter was "a limited public figure on the issue of obscenity in the mass media." Carpenter filed a motion for partial summary judgment on her claims of intentional infliction of emotional distress (IIED), negligent infliction of emotional distress, invasion of privacy by way of false light publicity and intrusion upon seclusion, and spoliation of evidence. The trial court issued an order granting in part and denying in part the parties' eross-motions for summary judgment. It dismissed Carpenter's claims of defamation, negligent infliction of emotional distress, and false light invasion of privacy. The court declined to grant summary judgment to either side on Carpenter's claims of IIED, intrusion upon seclusion, and intentional spoliation of evidence.
A jury trial was held on those claims. Leykis and Westwood One moved for a directed verdict at the close of evidence and the trial court took their motion under advisement. The jury found that Westwood One had engaged in intentional spoliation of evidence and awarded Carpenter $5,042 in compensatory damages and $150,000 in punitive damages. The jury also returned a verdict for Leykis and Westwood One on Carpenter's claims of IIED and intrusion upon seclusion and for Leykis on her spoliation claim. As to the spoliation claim, Westwood One's directed verdict motion was converted to a motion for judgment notwithstanding the verdict. The trial court ruled that the directed verdiet motions were moot as to the invasion of privacy and IIED claims; it denied the JNOV motion as to the spoliation claim.
Carpenter moved after trial for an order declaring AS 09.17.010(b) and AS 09.17.020(J) unconstitutional. Alaska Statute 09.17.010(b) imposes a cap on non-economic damages awards in personal injury and wrongful death cases. Because the jury's award did not include non-economic damages, the trial court dismissed as moot the portion of Carpenter's motion addressing AS 09.17.010(b). Alaska Statute 09.17.020(J) requires payment of fifty percent of a plaintiff's punitive damages award to the State of Alaska.2 The trial court ruled that AS 09.17.020(J) was constitutional. Carpenter also objected to the form of the judgment proposed by the defendants; she argued that the court should deduct from the punitive damage award the contingent fee (including her costs) she owed her attorneys before the court awarded one-half of the remainder to the state. The State of Alaska intervened to protect its interest in the punitive damages award. The trial court ruled that it would deduct the contingent fee from the punitive damages award before distributing one-half of the balance of the award to the state. The trial court issued a final judgment on June 27, 2002. On September 20, 2002, it denied Carpenter's motion to deduct fifty percent of her costs from the state's portion of the punitive damages award.
Leykis, Westwood One, and Carpenter all moved for attorney's fees. The trial court denied all fees motions and ordered the parties to bear their own fees and costs.
In Case No. S-10709 Carpenter appeals the trial court's grant of summary judgment against her on her defamation and false light claims. She also appeals two jury instructions, two evidentiary rulings, the ruling on the constitutionality of AS 09.17.020(J), and the denial of her motion to deduct costs from the state's share of the punitive damages award.
In Case No. S-10789 Westwood One appeals the denial of its JNOV motion on the spoliation claim, and also appeals the constitutionality and amount of the punitive damages award; Westwood One and Leykis appeal the denial of their motion for prevailing party attorney's fees and costs.
In Case No. S-10700 the state appeals the pro rata deduction of Carpenter's attorney's contingency fee from the state's share of the punitive damages award.
IH. DISCUSSION
A. The Superior Court Did Not Err in Granting Summary Judgment Against Carpenter on Her Defamation Claim.
Carpenter appeals the superior court's grant of summary judgment to Leyk-[51] is and Westwood One on Carpenter's defamation claim.3 We review grants of summary judgment de novo,4 considering the facts presented in a light most favorable to the non-movant to determine whether any genuine issues of material fact exist and whether the movant is entitled to judgment as a matter of law.5 We apply our independent judgment to constitutional law issues.6
The elements of a defamation claim are: (1) a false and defamatory statement; (2) unprivileged publication to a third party; (3) fault amounting at least to negligence; and (4) either per se actionability or special damages.7 A defamatory statement " 'tends to harm the reputation of another so as to lower [her] in the estimation of the community or deter third persons from associating or dealing with [her].'" 8 An expression of opinion is defamatory if the expression contains an implied assertion of false fact and is sufficiently derogatory as to cause harm to the subject's reputation.9 It is not necessary that the communication actually cause harm to another's reputation; its character depends upon its general tendency to do so.10 "If the context demonstrates to the audience that the speaker is not purporting to state or imply actual, known facts, the speech cannot be the basis for a defamation claim." 11
The common law rule that a pure expression of opinion may serve as the basis for a defamation action was rendered unconstitutional by recent United States Supreme Court decisions. The Supreme Court has held that the First Amendment bars defamation actions if the allegedly defamatory statements are pure expressions of opinion, not implied or stated assertions of false fact.12 The Court recognized that "[the freedom to speak one's mind is not only an aspect of individual liberty-and thus a good unto itself-but also is essential to the common quest for truth and the vitality of society as a whole." 13
The superior court granted summary judgment against Carpenter on her defamation claim, reasoning that Leykis's statements "about Ms. Carpenter ... [were] opinionated insults" protected by the First Amendment. The court held that Leykis's statements were "hyperbole, used only for shock value, and d[id] not state or imply any factual basis." We agree.
In Sands v. Living Word Fellowship, we explained: "[tlo ascertain whether a statement is factual, courts consider 'the type of language used, the meaning of the statement in context, whether the statement is verifiable, and the broader social cireumstances in which the statement was made.'" 14 Many of [52] Leykis's remarks about Carpenter were pure insults that were not factually verifiable. Even those statements that could constitute implied factual assertions, such as those about Carpenter's sexual habits, were not "factual" under the cireumstances. No listener would understand Leykis's remarks about Carpenter's sexual habits to imply actual facts about Carpenter. Sex-related jokes were a common feature of the show. Even if Leykis's remarks implied that Carpenter was in fact sexually frustrated and deprived, no reasonable listener would believe that Leykis was purporting to reveal actual, known facts about Carpenter.15 While Leykis's statements were offensive to any rational person, they were not defamatory.16
On appeal, Carpenter argues that the distinction between fact and opinion is inappo-site because Leykis's statements fell within categories of speech that are not protected by the First Amendment. She offers three grounds on which to hold that the speech was unprotected: (1) it was indecent speech broadcast when children would likely hear it; (2) it was obscene; and (8) it constituted fighting words.
For her first argument she relies on the United States Supreme Court's decision in FCC v. Pacifica Foundation.17 That decision does not support her claim, however, as it only decided whether the government has the power to regulate indecent speech that is broadcast by radio at times when children are likely to overhear it.18 Pacifica held that indecent speech is not entitled to absolute constitutional protection and that under limited cireumstances, the Federal Communications Commission may constitutionally regulate it. The ageney may not prohibit the speech entirely, however; it may only channel the communication. Thus the speech is unprotected only insofar as it subject to the agency's time, place, and manner restrictions. The decision is therefore inapplicable to Carpenter's defamation claim.
Carpenter's other two arguments also fail. Leykis's statements, however offensive, do not satisfy the three-pronged test for obscenity set out in Miller v. California.19 Likewise, they do not fall within the classic "fighting words" category of unprotected speech. The "fighting words" exception is limited to words that "by their very utterance ... tend to incite an immediate breach of the peace."20 Leykis's statements, uttered over the radio, were unlikely to achieve "an immediate breach of the peace." They may have encouraged listeners to retaliate against Carpenter, presumably by telephoning or faxing her at home. An exhortation for action of that sort is relevant to Carpenter's IIED claim. See Part IIIC. But his words are insufficient to be the basis for a defamation claim based on a theory that Leykis uttered "fighting words."
B. The Superior Court Did Not Err in Granting Summary Judgment Against Carpenter on Her False Light Invasion of Privacy Claim.
Carpenter argues that the superior court erred in granting summary judg[53] ment to Leykis on her claim of false light invasion of privacy. A false light invasion of privacy claim arises when the defendant publicizes a matter that places the plaintiff before the public in a false light.21 In many cases, the publicity is defamatory, although a plaintiff need not show injury to reputation to prevail on a false light claim.22 An action for false light invasion of privacy differs from an action for defamation because a defamation claim redresses damage to reputation while a false light privacy claim redresses mental distress from exposure to public view.23 Like defamation liability, however, false light lability requires at least knowing or reckless disregard of the falsity of the assertion of fact.24 Because opinions cannot be proved false, they cannot give rise to false light liability.25 Carpenter's false light invasion of privacy claim relies on the same statements that formed the basis for her defamation claim. It therefore fails. As we explained in Part IIIA, Leykis's statements purportedly describing Carpenter were opinions, not false statements of fact.
C. Jury Instruction No. 17 Potentially Prevented the Jury from Considering Carpenter's IED Claim Against Leykis.
1. The claimed error
Instruction No. 18 expressly instructed the jury on the elements of Carpenter's intentional infliction of emotional distress (IIED) claim. But Carpenter argues that Instruction No. 17 erroneously restricted the jury's consideration of her IIED claim.
The text of Instruction No. 17 effectively prevented the jury from finding Leykis liable for words "spoken to or about" Carpenter unless the speech fell within either one of two narrow exceptions. Carpenter asserts that it was error to give that instruction because she was not a "public figure" and because even if Leykis's speech was entitled to some protection, the instruction erroneously stated the law as to her IIED claim.26
Carpenter contends that the jury must or could have applied Instruction No. 17 to her IIED claim, and that Special Interrogatory 1 also misdirected the jury as to that claim. That special interrogatory asked the jury to determine whether Leykis's remarks about Carpenter were "intended to provoke a hostile reaction under cireumstances where a clear and present danger of immediate violence existed." Because the jury answered "No" to that interrogatory, Carpenter reasons that Instruction No. 17 and Special Interrogatory 1 "must have" caused the jury to believe that it "had no choice but to conclude that nothing Leykis said about Carpenter could support her IIED claim." She concludes that the instructional error was prejudicial and that a properly instructed jury could have found that Leykis's outrageous conduct caused Carpenter severe emotional distress. "That outcome is entirely likely," she reasons, given that in answering Special Verdict Form Question (11), the jury found Leykis's conduct to be "outrageous."
Leykis argues that Instruction No. 17 correctly stated the law and did not prejudice [54] the jury's consideration of the IIED claim. Citing Alaska cases27 he argues that speech may be punished in only "the most limited circumstances," and, citing Hustler Magazine, Inc. v. Falwell,28 he argues that the First Amendment forecloses an IIED claim that is based on the same facts as a defective defamation claim. He contends that because Carpenter claimed "emotional distress inflicted through media speech," it was appropriate to instruct the jury on constitutional speech protections.
The propriety of jury instructions generally raises questions of law that are subject to the independent judgment standard of review.29 Jury instructions to which timely objections were made are therefore reviewed de novo.30 Special verdict forms are subject to the same standard of review as other jury instructions.31 Errors in jury instructions are not grounds for reversal unless the errors are prejudicial.32 An erroneous instruction is prejudicial if it can be said that the verdict may have been different had the instruction not been given.33
2. The jury instructions, special interrogatory, and special verdict form
This claim of error requires us to consider the effect of Instruction No. 17, Instruction No. 18, Special Interrogatory 1, and parts of the special verdiet form.
Instruction No. 17 told the jury it could not "consider" as a basis for liability "words spoken to or about" Carpenter unless the speech was unprotected for either of two reasons. It stated:
The law protects most speech. By example, statements of opinion, even if insulting or distasteful, are generally protected speech. -It is only in limited cireumstances that speech can be punished or be the basis of liability for damages. Therefore, you shall not consider words spoken to or about Karen Carpenter unless you find that the speech is not protected because of either of the following reasons:
(1) Speech that is intended to provoke a hostile reaction under cireumstances where a clear and present danger of immediate violence exists is not protected speech.
(2) Publication of private factual information about an individual with knowledge or in reckless disregard that disclosure of the factual information would be highly offensive to a person of ordinary sensibilities is not protected speech. A fact is "private" if (2) it is not known to the public, that is, not a public record and not information legally available to the public or the media; and (b) the private fact is of a kind that, if publicized, would be highly offensive to a reasonable person; and (c) the private fact is not newsworthy, that is, of legitimate concern or' interest to the public or an appreciable percentage of the public.
Instruction No. 18 explained the elements of Carpenter's IIED claim:
Karen Carpenter claims that Tom Leykis or Westwood One or its employees or agents intentionally inflicted emotional distress on her by virtue of a radio broadcast on July 24, 1998.
For Karen Carpenter to recover for this claim of intentional infliction of emotional distress, you must decide that it is more likely true than not true that Tom Leyk-[55] is'[s] or Westwood One['s] or its employee's conduct was extreme and outrageous and that he/they intentionally or recklessly caused Karen Carpenter severe emotional distress.
I will now define "extreme and outrageous conduct", "intentional", "reckless", "legal cause", and "severe emotional distress" for you.
There is no contention that this instruction was erroneous (although Leykis and West-wood One argue here, as they did below, that Carpenter's IIED claim should not have been submitted to the jury).
The superior court gave the jury special interrogatories with an instruction that it was to answer them before turning to the special verdict form. Special Interrogatory 1 asked: "Did Tom Leykis engage in speech related to Karen Carpenter that was intended to provoke a hostile reaction under circumstances where a clear and present danger of immediate violence existed?" The jury answered "No."
The court also gave the jury a special verdict form asking specific questions, including this question: "(1) Did Tom Leykis, by extreme and outrageous conduct, intentionally or recklessly inflict severe emotional distress on plaintiff Karen Carpenter?" The jury answered "No." The special verdict form also asked whether the jury found by clear and convincing evidence that "the conduct of Tom Leykis and/or Westwood One (or its employees or agents) was outrageous and thus subject to an award of punitive damages?" As to Leykis the jury answered "Yes."
3. Distinguishing between Carpenter's defamation/false-light claims and her IIED claims
The question we must decide here is whether, by prohibiting the jury from basing liability on "words spoken to or about" Carpenter unless it found the speech was unprotected for one of the two specified reasons, Instruction No. 17 may have prevented the jury from fully considering Carpenter's IED claim.34 The question is important because the conduct that she asserts was outrageous consists largely of Leykis's conduct in speaking words "to or about" Carpenter during the broadcast. The instructions did not define the phrase "words spoken to or about." The literal and common-sense meaning of that phrase encompasses all words spoken "to" Carpenter, and all words spoken "about" her. This meaning renders the instruction applicable to all words Carpenter alleges were actionable. Some of those words described Carpenter in derogatory and humiliating terms and were central to the defamation and false-light claims that we held above were properly dismissed. But other words did not purport to describe Carpenter. A jury might interpret these other words as having been intended to invite listeners to contact her and make her life a "living hell." We are concerned here with determining whether the instruction potentially prevented the jury from fairly considering whether broadcasting these latter words was outrageous conduct that could be the basis for TIED lability.
We assume that an IIED claim that turns on the truth or falsity of speech is subject to the same limitations that protect speech from claims of defamation. Thus, just as actual malice must be proved by a public figure who is claiming defamation, actual malice must also be proved by a public figure who is claiming IIED based on the same speech that gives rise to a defamation claim.35 Likewise, we assume that just as actual malice must be proved by a plaintiff claiming defamation that arises out of speech on a matter of public concern in Alaska,36 actual malice must be proved by a plaintiff who bases a claim of IIED on the same speech.37
[56] Carpenter argues that the superior court erroneously considered her to be a public figure and that Hustler Magazine, Inc. v. Falwell,38 which applied actual-malice defamation standards to an IIED claim brought by a public figure, consequently does not control Carpenter's IIED claim. The United States Supreme Court has identified two bases on which to find public figure status:
In some instances an individual may achieve such pervasive fame or notoriety that he becomes a public figure for all purposes and in all contexts. More commonly, an individual voluntarily injects himself or is drawn into a particular public controversy and thereby becomes a public figure for a limited range of issues.
