    OPINION
    ¶1       Plaintiffs—Jeff Krumwiede, the special administrator of the estate of decedent Willard
    Krumwiede, and Ruth Krumwiede, decedent’s wife—brought a cause of action against
    defendant—Tremco, Inc. (Tremco)—raising wrongful death, survival, and loss of consortium
    claims. They alleged that, while working as a window glazier, decedent used asbestos-
    containing products manufactured by Tremco, which caused decedent to develop
    mesothelioma and resulted in his death. Following a trial, the jury found in favor of plaintiffs.
    Tremco appeals, arguing it is entitled to a judgment notwithstanding the verdict (judgment
    n.o.v.) or a new trial. Alternatively, it argues it is entitled to a setoff for amounts paid in prior
    settlements with other defendants. We reverse.
    ¶2                                         I. BACKGROUND
    ¶3       In April 2013, plaintiffs filed their complaint against Tremco and more than 50 other
    defendants, alleging defendants manufactured and sold asbestos-containing products that
    decedent used or was exposed to while working as a window glazier. Plaintiffs alleged that
    defendants’ products gave off dust, decedent was exposed to that dust, and decedent contracted
    mesothelioma as a result of his exposure. Plaintiffs asserted that before manufacturing the
    products at issue, defendants knew or should have known “that exposure to asbestos caused
    pulmonary fibrosis and malignancies.” They alleged that defendants were negligent because
    defendants
    “a) failed to warn that exposure to asbestos fibers caused serious disease and death;
    b) failed to warn that exposure to asbestos fibers caused pulmonary fibrosis;
    c) failed to warn that exposure to asbestos fibers caused malignancies;
    d) failed to provide instruction as to safe methods, if any existed, of handling and
    processing asbestos containing products.”
    Plaintiffs further asserted that decedent died on September 26, 2012, and that defendants’
    negligence was a proximate cause of his injury and death.
    ¶4       In October 2017, the trial court conducted a jury trial. At the time of trial, Tremco remained
    the sole defendant in the case, and it is the only defendant at issue on appeal. With respect to
    Tremco, plaintiffs complained of decedent’s exposure to two asbestos-containing products,
    “440 Tape” and “Mono caulk.” Both products were manufactured using chrysotile-type
    asbestos fibers.
    ¶5       Evidence showed decedent worked as a window glazier, installing glass into wood or
    aluminum frames, from approximately the mid-1950s until his retirement in the early 1990s.
    On September 26, 2012, decedent passed away at the age of 81. An autopsy showed he had
    “malignant mesothelioma consistent with industrial exposure of asbestos.” Asbestos fibers
    were “identified within the lungs, microscopically.”
    ¶6       Plaintiffs presented the testimony of two of decedent’s coworkers, Dennis Schultz and
    Richard Darr. Both men worked as window glaziers with decedent in the 1960s and 1970s and
    testified that they frequently used Tremco’s Mono caulk and 440 Tape. Schultz asserted those
    products were used “[j]ust about every day” in their line of work. On a large job, he would use
    hundreds of tubes of Mono caulk and hundreds of feet of 440 Tape. He acknowledged using
    products from manufacturers other than Tremco but asserted that Tremco’s products were the
    -2-
    “most specked [sic] product[s] out there by architects.” Darr described the 440 Tape as the
    “primary tape” that he and decedent used.
    ¶7          The 440 Tape arrived at job sites packaged in a cardboard box with multiple rolls of tape
    per box. The tape was described as “tacky,” and Darr testified it would stick to his hands. The
    440 Tape had to be cut when applied to a window. Tremco’s Mono caulk was applied with a
    caulking gun. It also arrived in boxes with multiple tubes of caulk in each box. Schultz testified
    that on a four by five window, he would use a quarter to half a tube of caulk. Workers used
    their fingers to “smooth *** off” the caulk and razors to “scrape” it. The Mono caulk would
    get on rags and the workers’ clothing and hands.
    ¶8          Schultz denied observing any visible dust when cutting the 440 Tape or using the Mono
    caulk. While working with decedent, they worked in locations where insulators were present
    and wrapping pipes in their vicinity or general area. Schultz did not know if the insulators
    created any dust. Darr testified that he never saw any visible dust coming off of the Mono caulk
    or when cutting the 440 Tape. However, there were times when he and decedent had to remove
    the Mono caulk that had dried using a chisel. He stated they “could have run up some [visible]
    dust once in a while” but he did not remember.
    ¶9          Schultz testified that in the years he and decedent used Tremco’s 440 Tape and Mono
    caulk, he did not see “anything on the product[s] indicating that asbestos was one of the
    ingredients.” He also did not recall ever receiving any information from Tremco that asbestos
    was harmful and that it could cause asbestosis, lung cancer, or mesothelioma. Darr testified he
    did not pay attention to what Tremco’s products were made of and never saw information on
    the packaging indicating the products contained materials that were harmful or could cause
    lung disease. He first learned Tremco’s products contained asbestos in the 1990s.
    ¶ 10        Plaintiffs called Steven Milano, Tremco’s corporate representative with respect to asbestos
    litigation, as an adverse witness. Beginning in 1995, Milano worked on and off for Tremco as
    a staff chemist. In March 2016, he began working as Tremco’s director of research and
    development for construction, sealants, and waterproofing. Milano testified he reviewed more
    than 14,000 pages of documents concerning Tremco’s historical use of asbestos as well as the
    testimony of its previous corporate representatives on the subject. He agreed he was “the most
    knowledgeable person” regarding the subject of Tremco’s asbestos-containing products.
    ¶ 11        According to Milano, “all asbestos containing formulas” were removed from Tremco’s
    product offerings before he began working for Tremco in 1995. In 2006, Tremco’s legal
    counsel asked Milano to “mix up a batch of caulk” and “a batch of tape.” The tape was 440
    Tape but the caulk was not Mono caulk. Milano was provided with formulas to be used for the
    caulk and tape that were from Tremco’s “formulation records” from 1974 to 1982. Milano also
    received raw asbestos to use in the formulas. He testified that he understood he was
    remanufacturing products with old formulas so that they could be tested “for the purposes of
    litigation.” Milano made the requested products, and they were “shipped *** off to a lab called
    EPI.” According to Milano, the EPI testing was done “to show and demonstrate that no
    detectible [sic] asbestos fibers [were] released from” Tremco’s products.
    ¶ 12        Milano identified the Tremco facilities where asbestos-containing products were
    manufactured, including its Kinsman, Toronto, Barberville, and Columbus facilities. He
    agreed that such facilities used “raw bags” of asbestos. Milano testified that “Tremco’s
    understanding of asbestos related hazards developed with the onset of [the Occupational Safety
    and Health Administration (OSHA) regulations on asbestos] in the early ’70s and progressed
    -3-
    from there.” More specifically, he agreed that Tremco knew about potential hazards associated
    with raw asbestos fiber in 1971. He also testified that Tremco had knowledge that asbestos
    could be harmful in “[t]he late ’60s to early ’70s.”
    ¶ 13        According to Milano, Tremco began making “efforts at the onset of OSHA to start trying
    to find alternatives to asbestos in [its] products.” In 1974, it had a goal of becoming asbestos-
    free. Tremco did not succeed in its goal until 15 to 20 years later.
    ¶ 14        Milano identified internal correspondence from Tremco and other documents describing
    the condition of Tremco’s Kinsman facility, where Tremco manufactured roofing materials.
    Those documents were admitted into evidence and showed that in November 1971, a Tremco
    employee described Tremco’s Kinsman facility as being “grossly negligent” in areas subject
    to OSHA regulations. One problem identified in the correspondence involved the use of
    asbestos as a “sweeping compound.” In June 1974, violations were noted in the area of
    “asbestos usage” and asbestos handling at the plant was described as “poor.” In January 1973,
    air samples from Tremco’s Kinsman facility were above recommended limits. Additionally,
    an OSHA inspection in December 1974 found various violations, including Tremco’s failure
    to post caution signs at entrances to the asbestos area and to “ensure that all places of
    employment be maintained free of accumulations of asbestos fibers if with their dispensing
    there would be an excessive concentration.”
    ¶ 15        Milano agreed that Tremco was an Illinois employer and should have known about the
    Illinois Workers’ Occupational Diseases Act. Plaintiff submitted portions of that act as an
    exhibit and Milano acknowledged that, in March 1936, it referenced employer liability in cases
    of asbestosis, a nonmalignant disease caused by asbestos. He further testified that Tremco’s
    headquarters was in Ohio and acknowledged that Ohio had regulations in 1947 regarding
    acceptable limits regarding exposure to asbestos in an employment setting. Milano agreed that
    given the Ohio regulations, “Tremco would have known that there was potential harm with
    asbestos.” He acknowledged that “Tremco knew in the ’40s asbestos could be harmful.”
    ¶ 16        Milano further identified a brochure produced and distributed by Tremco in 1987, entitled
    “WHY WAIT?” The brochure noted that the Environmental Protection Agency (EPA)
    proposed a rule to ban certain asbestos products and to phase out the use of asbestos over the
    next 10 years. It also stated that the EPA had concluded that “ ‘no level of exposure is without
    risk.’ ” According to Milano, the “WHY WAIT?” brochure came out of Tremco’s roofing
    division. Further, to his knowledge, decedent was never an employee of Tremco and did not
    work at any of its manufacturing facilities.
    ¶ 17        Plaintiffs next presented the testimony of Dr. Arthur Frank, their retained medical expert.
    Dr. Frank testified he was a board-certified physician in both internal and occupational
    medicine, held a Ph.D. in biomedical sciences on the subject of asbestos and how it affects
    respiratory tissue, and had performed asbestos-related research since 1968. He described
    mesothelioma as a cancer of the pleura, or lining of the lung, and other similar tissues. In the
    United States, mesothelioma “is virtually only caused *** by exposure to asbestos.”
    ¶ 18        According to Dr. Frank, in “modern history,” information regarding the health hazards of
    asbestos went back to the late 1890s. There were articles on the subject in the early 1900s, and
    the term asbestosis was coined in 1924. In 1942, the head of occupational cancer studies at the
    National Cancer Institute reported that he considered asbestos to be a cause of lung cancer. Dr.
    Frank testified that asbestosis, lung cancer, and mesothelioma could all be fatal diseases and
    he had never seen a “cured case of mesothelioma.”
    -4-
    ¶ 19        Dr. Frank identified “six fibers that collectively are called asbestos.” He described the
    fibers as “extremely small” and stated that all of them caused disease. Dr. Frank acknowledged
    that some individuals were of the opinion that chrysotile asbestos fibers, unlike other fiber
    types, could not cause mesothelioma. However, he disagreed, stating there was “[r]eally
    nothing that supports” such opinions and that all of the government agencies in this country
    “recognize that all fiber types, including chrysotile, cause mesothelioma.” Dr. Frank testified
    that seeing “what fibers are in the lung” is not a way of determining what asbestos fibers a
    person inhaled. He noted that the different types of fibers stayed in the lung for different
    amounts of time. Crocidolite and amosite fibers “take up residence in the lung, and they tend
    to stay there” and have a half-life of two to three years. Alternatively, for chrysotile fibers, “the
    average half-life is about 90 days.” The fact that a fiber leaves the lung does not mean that it
    leaves the body. Dr. Frank stated that chrysotile fibers are “the fiber that most readily gets out
    to the pleura” where mesothelioma occurs.
    ¶ 20        Dr. Frank stated that there is no known safe level of exposure to asbestos. Because asbestos
    is a naturally occurring mineral, “we all have some exposure” (i.e., “background” or “ambient”
    exposure). When questioned by plaintiffs’ counsel regarding how regularly and frequently a
    person must be exposed to asbestos to develop mesothelioma, Dr. Frank testified that “it’s not
    something that requires many, many years or constant ongoing exposure.” He stated as follows:
    “Again, one time will do it. So there’s no set frequency. Obviously it’s a very simple
    principle. We call it the dose-response relationship. The more you’re exposed, the
    greater the dose, the more likely you are to get disease.
    So someone who’s exposed for a week has a certain risk. For a year, their risk would
    be higher, assuming the same levels. And then, you know, if they work for four decades
    or two decades or whatever, the risk is going to be even higher because the exposure
    was higher over time.”
    Dr. Frank asserted that there was no scientific way to determine which exposure to asbestos
    caused a person to develop a disease, stating: “It is the cumulative exposure, the totality of the
    exposure that we say that causes the disease.”
    ¶ 21        Regarding the ability of asbestos-containing products to release asbestos fibers, Dr. Frank
    testified as follows:
    “I’ve been doing this work a long time, and there’s not a single product I’ve ever come
    across that has not had the capacity to give up fibers when worked with. I mean, you
    think of something like asbestos cement pipe. You would think, well, you know, a piece
    of cement, it’s not going to give up fibers.
    But if you cut it, drill it, bevel it, you know, work with it the way pipe is worked
    with, even there, asbestos fibers will come out. And when the water flows through it,
    because it’s often used for water system piping, it pulls out asbestos fibers even out of
    something like cement. So there isn’t a product that doesn’t have the ability to give up
    asbestos.”
    Dr. Frank maintained that even encapsulated asbestos products can give off respirable fibers.
    The following colloquy occurred between Dr. Frank and plaintiffs’ counsel:
    “Q. Doctor, in the course of your—of the last 40 years of doing this, have any of
    the cases you’ve looked at involved rubber or butyl tape or—or a caulking for windows
    or doors?
    -5-
    A. Yes *** they have.
    Q. Can those products give off asbestos?
    A. Yes, they can.”
    ¶ 22       Dr. Frank stated that decedent’s medical record showed “that he developed a malignant
    pleural mesothelioma.” He opined that mesothelioma was his cause of death. Additionally, the
    asbestos fibers that were found in decedent’s lung indicated that he “had significant prior
    exposure to asbestos.”
    ¶ 23       Plaintiffs’ counsel asked Dr. Frank to assume that decedent worked as a window glazier,
    using “caulk daily during [his] career” and, during the 1960s and 1970s, using “asbestos-
    containing tape.” Based on such facts, Dr. Frank opined decedent’s “exposures to asbestos
    would have caused him to develop the mesothelioma that he had that caused his death.” He
    testified that when a person is exposed to respirable asbestos fibers in their work, that exposure
    is “above background.” Dr. Frank further opined “that all of the exposures that [decedent] had
    from any and all products of any and all fiber type would have contributed to his developing
    his mesothelioma.” He stated that the overall totality of what a person is exposed to, the
    cumulative dose, is what is implicated in mesothelioma.
    ¶ 24       On cross-examination, Dr. Frank testified that background levels of asbestos were “many
    orders of magnitude less than what’s legally allowed in the workplace.” When discussing
    exposure to asbestos as causative of disease, it was his view that “[i]t’s all the exposures
    together that give you the cumulative exposure.” Dr. Frank also stated that the cumulative
    exposure “may come from multiple sources.”
    ¶ 25       He explained that respirable fibers meant “fibers that can actually get down into the lung.”
    He testified some fibers were too big and “won’t get down there.” Dr. Frank agreed that “the
    testing and the determination of the extent to which measurable asbestos fibers are released
    during the manipulation of any particular product” was “not the kind of work that” he
    performed. Rather, that kind of work was performed by industrial hygienists, mineralogists,
    engineers, or geologists. Further, he agreed that such testing would help determine the “dose,”
    or how much asbestos entered the body, from any particular product. The following colloquy
    then occurred between Tremco’s counsel and Dr. Frank:
    “Q. And as I understand your general opinion, it is that any and every exposure
    over background constitutes a substantial contributing factor in the development—
    development of asbestos-related disease, and that includes as it specifically relates to
    [decedent’s] mesothelioma. Do I understand that correctly?
    A. All of the exposures that he had to any and all products with any and all fiber
    types contributed to his disease. I can’t sit here and tell you what his relative exposure
    was to product A, B, C, D, E, or F. I can just say whatever can be documented that he
    was exposed to, they would all be part of his cumulative exposure.
    ***
    Q. Is it your opinion then that each and every fiber above background is part of the
    overall contribution to someone’s cumulative exposure?
    A. No, that is not my opinion. My opinion is that it is the cumulative exposure, all
    of the fibers together, that give someone disease.
    ***
    -6-
    Q. Well, let me ask you this. Isn’t it your opinion that in terms of exposure that is
    causative it’s either zero or it’s substantial; there’s no such thing as not substantial?
    A. There is no such thing as an amount of exposure that doesn’t contribute to one’s
    cumulative exposure. It goes back to that cigarette example. Either you have to say that
    one cigarette is insubstantial or that they were all substantial because they made up
    collectively the cumulative exposure.”
    Dr. Frank testified that “some exposures are more and some are less, but you can’t leave any
    of them out. So it’s either zero or it contributed.”
    ¶ 26       Plaintiffs also presented the testimony of Dr. John Migas, a board-certified physician in
    the areas of internal medicine and oncology, who treated decedent during his lifetime for colon
    cancer. Dr. Migas described his treatment of decedent, which included six months of
    chemotherapy. He stated that, in September 2011, decedent’s colon cancer appeared to be in
    complete remission.
    ¶ 27       Dr. Migas described the medical treatment decedent received immediately prior to his
    death in September 2012 and about the relationship between asbestos and mesothelioma. He
    stated that asbestos can cause mesothelioma. According to his training, there are multiple
    asbestos fibers and all of the fibers could cause mesothelioma. Dr. Migas stated he had seen
    approximately 50 cases of mesothelioma during his career and all of them had histories
    involving exposure to asbestos. Some of his patients had long-standing exposures as a result
    of the patient’s employment. The shortest case of exposure “was a weekend exposure.” Dr.
    Migas testified that some of his patients also had been exposed to asbestos from more than one
    place. He stated that “it appears that the more asbestos that you take in per time element seems
    to be consistent with a higher risk.”
    ¶ 28       Plaintiffs’ counsel asked Dr. Migas to assume that decedent worked as a window glazier
    from 1956 until 1991; from the 1950s to the 1980s he worked daily with asbestos-containing
    tapes and caulk; and he worked around other “construction trades” performing their duties,
    including insulators. Based on those facts, Dr. Migas opined that “if there is asbestos
    containing [sic] and he had mesothelioma, I think that those could all be implicated as a risk
    that could have potentially caused mesothelioma.” When using the word “risk,” he meant that
    something was “more likely than not a contributor.”
    ¶ 29       On cross-examination, Dr. Migas agreed that he treated decedent only in connection with
    his diagnosis of colon cancer and not for anything related to mesothelioma. He did not hold
    himself out as an expert in the field of asbestos medicine and had not done any research in that
    area. Dr. Migas also agreed that if testing on an asbestos-containing product resulted in no
    release of detectable respirable fibers, then the product would not be a risk factor for an
    asbestos-related disease.
    ¶ 30       After plaintiffs rested, Tremco moved for a directed verdict, arguing plaintiffs failed to
    meet their burden of establishing that decedent was exposed to asbestos fibers from its products
    or that exposure to asbestos fibers from its products was a substantial factor in causing
    decedent’s mesothelioma. In response, plaintiffs’ cited Dr. Frank’s testimony that “all products
    release fibers,” that he was familiar with butyl tapes and caulking, and that such products
    “release fibers.” The trial court denied the motion.
    ¶ 31       As part of its case, Tremco presented the testimony of Dr. Michael Graham, a forensic
    pathologist. Dr. Graham reviewed decedent’s medical records, depositions from decedent’s
    -7-
    coworkers, and microscopic slides from decedent’s tissues. He noted various medical issues
    that decedent had, including colon cancer in 2010, heart disease, and malignant mesothelioma.
    Dr. Graham testified that decedent’s autopsy established the presence of mesothelioma. It “also
    established the presence of an increased amount of asbestos and specifically amosite asbestos
    in [decedent’s] lung tissue and no increase in any other type.”
    ¶ 32       Dr. Graham opined that “the primary cause” of decedent’s death was his malignant
    mesothelioma and that his heart disease was also “involved.” He stated there are two major
    groups of asbestos—the serpentine group, which is the chrysotile-type of asbestos fibers, and
    the amphibole group, which included amosite and crocidolite asbestos fibers. Dr. Graham
    opined that amphibole asbestos caused malignant mesotheliomas in humans. With respect to
    decedent, the autopsy showed that “[t]he only fibers that were found in an abnormal
    concentration in more than anybody just walking around *** were amosite fibers.” According
    to Dr. Graham, amphiboles could “stick around” in tissue for decades, having more time to do
    damage. Dr. Graham acknowledged that there was “some controversy” regarding the
    relationship between exposure to chrysotile asbestos fibers and mesothelioma. He opined that
    heavy prolonged exposure to contaminated chrysotile fibers could cause pleural
    mesotheliomas.
    ¶ 33       According to Dr. Graham, decedent’s mesothelioma was due to amosite fibers. He testified
    decedent may have been exposed to amosite asbestos from working around pipefitters and
    insulators in the sixties who worked with thermal insulation. Dr. Graham also opined that
    decedent’s work with Tremco’s products “had nothing to do” with his development of
    mesothelioma.
    ¶ 34       On cross-examination, Dr. Graham acknowledged that he was not a “researcher in the area
    of asbestos or asbestos disease.” He testified he occasionally made a diagnosis of asbestos-
    related diseases, but he did not treat patients with such diseases. Dr. Graham agreed “that the
    majority of *** asbestos fibers that get to the pleura are short chrysotile fibers.” He opined that
    Tremco’s products “wouldn’t release any significant amount of fiber” and “certainly not
    enough” to cause an asbestos-related disease. Dr. Graham acknowledged various published
    journals, articles, and studies that set forth the conclusion that chrysotile fibers were
    mesothelioma-producing fibers.
    ¶ 35       Tremco also presented the testimony of Dr. William Longo. Dr. Longo stated he had a
    doctorate in materials science and engineering. He was the president of Materials Analytical
    Services (MAS), a company that provided consulting and laboratory analysis services. Dr.
    Longo stated MAS was certified to do EPA work for the analysis of asbestos and certified by
    the American Industrial Hygiene Association to perform fiber counting by optical and
    transmission electron microscopy. Since 1998, MAS “processed and analyzed” approximately
    400,000 to 450,000 asbestos samples, both bulk and air samples.
    ¶ 36       At Tremco’s request, MAS studied the Mono caulk and 440 Tape. Tremco provided the
    products, and Dr. Longo was personally involved in the testing and analysis of those products.
    He stated that both optical microscopes, also referred to as phase contrast microscopy (PCM)
    analysis, and transmission electron microscopes were used by MAS to analyze asbestos
    samples from Tremco’s products. Optical microscopes were used in protocols specified by
    OSHA and could “magnify up to about 2000 times” or 3000 to 4000 times with computer
    enhancement. Alternatively, a transmission electron microscope, or TEM analysis, was
    -8-
    mandated by the EPA to test air samples for schools and was more powerful. Dr. Longo stated
    an electron microscope “can magnify up to one to two to [three] million times.”
    ¶ 37       Dr. Longo testified a bulk sample analysis of Tremco’s 440 Tape was done to determine
    asbestos content of the product. From that analysis, it was determined that the 440 Tape
    contained chrysotile asbestos and that the percentage of asbestos in the tape was approximately
    22%. A bulk sample analysis of the Mono caulk showed that it also contained chrysotile
    asbestos fibers and that the amount of asbestos in the caulk was 0.3 to 0.5%. Although MAS
    did not perform a full analytical analysis of the products submitted for testing, both products
    had the same properties as their historical specifications.
    ¶ 38       Dr. Longo next described conducting work practice studies on both of Tremco’s products.
    He stated a work practice study involved performing work activities or “worst case scenario”
    activities to determine if a product would release measurable amounts of respirable asbestos
    fibers. With respect to Tremco’s 440 Tape, Dr. Longo testified that the product he analyzed
    was made in 2006 by Milano for testing purposes. The work practice study performed on the
    440 Tape involved handling the tape and cutting the tape 70 times over a 10-minute period.
    Air samples were taken from six inches from the mouth and nose of the person performing the
    test, as well as seven to eight feet away from the work activity. Dr. Longo testified they also
    studied the clothing of the individual performing the testing. Results of the air sample analysis
    on the 440 Tape showed that “the amount of asbestos fibers in the air for an occupational
    exposure was too low for [MAS] to detect.” Dr. Longo testified as follows:
    “The amount of—the amount of asbestos fibers in the air for an occupational
    exposure was too low for us to detect it with our technique so we came up with zero
    amount of asbestos fibers for our analysis, and that was both PCM and transmission
    electron microscopy.
    So we have a certain detection limit, meaning I can only analyze so far, and I can
    only go to that amount that is our detection limit detecting 1 fiber. If it is below that
    concentration, we can’t detect it. So it was below our ability to analyze and to detect
    the asbestos so we would say that it was below our detection limit.”
    ¶ 39       Regarding the Mono caulk, Dr. Longo testified that MAS received a sample that was
    estimated to have been manufactured in the early 1980s and not “in its original form, meaning
    you couldn’t stick that cartridge in a caulking gun and actually caulk something with it because
    it had hardened.” He also testified that the caulk sample “had been already analyzed once by
    another lab” and had “an actual hole or flap cut out of the—it was in a cardboard tube where
    the sample had been taken.” Dr. Longo then testified as follows regarding the work practice
    study performed on the caulk:
    “So we thought about it and determined that the worst case scenario for a potential
    exposure for a glazier, in my opinion, is coming back later and removing the material,
    such as the window broke and you have to replace it.
    The initial application of the material, it’s in a—if you’ve all seen caulk, it’s in a
    very tacky, sticky form and that typically doesn’t release asbestos fibers, they’re all
    wrapped up into the—I think of flypaper, they’re all stuck in there.
    So what we did was *** we took the Tremco cartridge and we cut the section of
    cardboard off to expose, say, a half barrel of the hardened caulk and took an electric
    -9-
    drill with a brass grinder and actually ground off an eighth inch of the top of the barrel
    of the caulk.”
    According to Dr. Longo, testing also involved cutting strips of the caulking off, putting it into
    an oven at 230 degrees Fahrenheit for 24 hours to harden it, and then grinding it off with a drill
    and a wire brush. Dr. Longo stated that, like with the 440 Tape, air sample testing did not detect
    “any measurable amounts of asbestos fibers.” Also, analysis of the clothing worn by the
    individuals testing both products showed “the amount of asbestos contamination transmitted
    to the clothing was below the detection limit of the method.”
    ¶ 40       Dr. Longo testified that Tremco’s products were thermoplastic materials, which always
    stayed “pliable” and had a “stickiness.” Such materials were unique and did not behave the
    same way as other asbestos-containing materials that release asbestos fibers when subjected to
    grinding. When asked whether Tremco’s 440 Tape would release measurable or detectable
    respirable asbestos fibers if sawed, sanded, cut, ground, or abraded, Dr. Longo opined as
    follows:
    “It would be my opinion that using this product would not produce any significant
    exposure in an occupational setting. I can’t say that it doesn’t release any fibers. It’s
    sort of like any analytical technique. If somebody comes out and says that this material
    will never release [one] fiber or any fibers, he’s just making that up.
    All you can say is I’ve measured it using the standard protocols that are used in
    industrial hygiene situations for occupational exposures and I cannot detect any fibers.”
    Dr. Longo stated he had the same opinion with respect to Tremco’s Mono caulk.
    ¶ 41       On cross-examination, Dr. Longo testified that permissible exposure limits under OSHA
    were “based on the optical microscope PCM counts.” He stated “to be counted, an asbestos
    structure or fiber has to be a certain length and a certain width. [It] [h]as to be greater than 5
    micrometers in length and greater than about [0].2 micrometers wide for the optical
    microscopist to actually see the fiber.” Dr. Longo also testified that the typical individual
    chrysotile fiber was not 0.2 micrometers wide. For chrysotile fibers to be observed on an
    “optical or PCM microscope,” there would “have to be a bundle of fibers.” Dr. Longo agreed
    that when chrysotile fibers are released in what he would consider a significant amount, 80%
    to 85% of the fibers “are smaller than what allows them to [be] characterize[d] as an OSHA
    fiber.” Further, a dust count using the optical microscopy system and OSHA fiber definition
    or protocol would reflect “only a very small percentage of the actual chrysotile fibers that are
    in the air.”
    ¶ 42       Dr. Longo agreed that he was not a medical doctor and did not give opinions on medical
    causation for asbestos disease. Further, the question of how many or how few respirable
    asbestos fibers put someone at risk for disease was “not [his] area.” The potential toxicity of
    asbestos fibers that were not observed under OSHA standards with optical microscopy was
    also for others to determine and not within his area of expertise.
    ¶ 43       When referencing “detection limits” in connection with the testing MAS performed, Dr.
    Longo was referencing “OSHA fibers and concentration of OSHA fibers.” He agreed that the
    objective of the testing was to use OSHA criteria for determining “whether or not there was
    any significant occupational exposure.” The following colloquy occurred between plaintiffs’
    counsel and Dr. Longo:
    - 10 -
    “Q. Okay. *** In other words, you’re not saying that [decedent] was exposed or
    not exposed to respirable asbestos fibers from his usage of Tremco products, you’re
    saying that based on your testing it was not a significant level of exposure; is that
    correct?
    A. That’s correct. Nobody can say that there wasn’t one or [two] fibers by chance
    that got released, but there’s no way to detect it. And in the method we use there’s no
    way to detect that.
    In this particular case, this particular product using the OSHA protocols at—to our
    detection limit there was no exposure. Once you start going below our detection limit,
    certainly couldn’t rule out a fiber or two, but nothing significant.”
    Dr. Longo testified that testing results for Tremco’s products were below OSHA’s “level for
    what [it] deem[s] important.” On redirect examination, Dr. Longo clarified that MAS’s testing
    of Tremco’s products used a transmission electron microscope to identify respirable asbestos
    fibers.
    ¶ 44       Ultimately, the jury returned a verdict in favor of plaintiffs and against Tremco. It assessed
    damages totaling $5,063,324.52.
    ¶ 45       In March 2018, Tremco filed a posttrial motion, seeking a judgment n.o.v. or a new trial
    on all issues. It alternatively sought a setoff for amounts plaintiffs received from other
    settlements. Following a hearing in June 2018, the trial court denied Tremco’s requests for a
    judgment n.o.v. and a new trial. However, “[a]s a result of set offs,” it entered a modified
    judgment in favor of plaintiffs and against Tremco in the amount of $3,272,083.31.
    ¶ 46       This appeal followed.
    ¶ 47                                         II. ANALYSIS
    ¶ 48                                       A. Judgment N.O.V.
    ¶ 49       On appeal, Tremco first argues that it is entitled to a judgment n.o.v. It contends plaintiffs
    failed to prove causation because they presented no competent or admissible evidence that
    Tremco’s Mono caulk or 440 Tape released respirable asbestos fibers. Tremco also argues that,
    assuming its products did release respirable asbestos fibers, plaintiffs presented no competent
    evidence that decedent was exposed to those fibers with “ ‘such frequency, regularity and
    proximity’ ” that they could be viewed as a substantial factor in causing decedent’s
    mesothelioma.
    ¶ 50       A motion for judgment n.o.v. raises the same questions and is governed by the same rules
    of law as a motion for a directed verdict. Lawlor v. North American Corp. of Illinois, 
    2012 IL 112530
    , ¶ 37, 
    983 N.E.2d 414
    . Such motions present a question of whether “there is a total
    failure or lack of evidence to prove any necessary element of the [plaintiff’s] case.” (Internal
    quotation marks omitted.) 
    Id.
     “In ruling on a motion for a judgment n.o.v., a court does not
    weigh the evidence, nor is it concerned with the credibility of the witnesses; rather, it may only
    consider the evidence, and any inferences therefrom, in the light most favorable to the party
    resisting the motion.” Maple v. Gustafson, 
    151 Ill. 2d 445
    , 453, 
    603 N.E.2d 508
    , 512 (1992).
    Ultimately, “[a] motion for judgment n.o.v. should be granted only when all of the evidence,
    when viewed in its aspect most favorable to the opponent, so overwhelmingly favors [a]
    movant that no contrary verdict based on that evidence could ever stand.” (Internal quotation

     On appeal, we apply a de novo standard of review. 
    Id.
    ¶ 52       In negligence actions such as this one, a necessary element of proof “is that the defendant’s
    asbestos was a ‘cause’ of the decedent’s injuries.” Thacker v. UNR Industries, Inc., 
    151 Ill. 2d 343
    , 354, 
    603 N.E.2d 449
    , 455 (1992). “[C]ausation requires proof of both ‘cause in fact’ and
    ‘legal cause.’ ” 
    Id.
     A plaintiff may not “take the causation question to the jury when there is
    insufficient evidence for the jury to reasonably find that the defendant’s conduct was a cause
    of the plaintiff’s harm or injury.” 
    Id. at 355
    .
    ¶ 53       In asbestos cases, a plaintiff may prove “cause in fact” under the “substantial factor” test,
    whereby “the defendant’s conduct is said to be a cause of an event if it was a material element
    and a substantial factor in bringing the event about.” 
    Id. at 354-55
    . In Thacker, the supreme
    court adopted the “ ‘frequency, regularity and proximity’ test as a means by which an asbestos
    plaintiff can prove more than minimum contact to establish that a specific defendant’s product
    was a substantial factor in being a cause in fact of a plaintiff’s injury.” Nolan v. Weil-McLain,
    
    233 Ill. 2d 416
    , 432, 
    910 N.E.2d 549
    , 558 (2009) (citing Thacker, 
    151 Ill. 2d at 359
    ). Under
    that test, the plaintiff must show that the “injured worker was exposed to the defendant’s
    asbestos through proof that (1) he regularly worked in an area where the defendant’s asbestos
    was frequently used and (2) the injured worker did, in fact, work sufficiently close to this area
    so as to come into contact with the defendant’s product.” Thacker, 151 Ill. 2d at 359.
    “In addition, by adopting the [frequency, regularity, and proximity test], Thacker
    thereby rejected the argument *** that so long as there is any evidence that the injured
    worker was exposed to a defendant’s asbestos-containing product, there is sufficient
    evidence of cause in fact to allow the issue of legal causation to go to the jury.”

    ¶ 54                             1. Release of Respirable Asbestos Fibers
    ¶ 55       Here, Tremco initially argues plaintiffs’ evidence was insufficient to show causation
    because plaintiffs presented no competent or admissible evidence that Tremco’s products
    released respirable asbestos fibers. It contends that Dr. Frank’s testimony on the subject was
    based on unsubstantiated speculation. Tremco cites this court’s recent decision in McKinney v.
    Hobart Brothers Co., 
    2018 IL App (4th) 170333
    , 
    127 N.E.3d 176
    , to support its argument.
    ¶ 56       In McKinney, the plaintiff alleged he developed mesothelioma after inhaling asbestos fibers
    from the defendant’s asbestos-containing welding rods. Id. ¶ 1. A jury returned a verdict in the
    plaintiff’s favor, and the defendant appealed. Id. On review, this court reversed, finding the
    defendant was entitled to a judgment n.o.v. on two alternative bases. Id. ¶¶ 74, 83.
    ¶ 57       In considering the issues presented for review, we addressed challenges to the testimony
    and opinions of the plaintiff’s retained expert, Dr. Frank—the same Dr. Frank who testified in
    the case at bar. In McKinney, Dr. Frank opined that the defendant’s welding rods were capable
    of giving off respirable asbestos fibers. Id. ¶ 17. As a basis for his opinion, Dr. Frank testified
    that “in his decades of experience with asbestos, [he] had never known of an asbestos-
    containing product that, if ‘properly manipulated,’ would not give off asbestos fibers.” Id. Dr.
    Frank also relied on “ ‘the work of Dr. Dement with fibers being released from welding rods.’ ”
    Id.
    - 12 -
    ¶ 58       On appeal, the defendant complained that Dr. Frank’s fiber-release testimony was
    inadmissible because “ ‘it was not the product of a reliable methodology.’ ” Id. ¶ 40. Initially,
    this court agreed that Dr. Frank’s opinions were speculative to the extent that they were based
    on never having seen an asbestos-containing product that did not release asbestos fiber. Id.
    ¶ 44. Specifically, we stated as follows:
    “We agree it would be ‘sheer, unsubstantiated speculation’ [citation] to conclude
    that, simply because other asbestos-containing products, such as cement pipes, released
    respirable asbestos fibers when they were sawed, cut, or beveled, [the] defendant’s
    welding rods released respirable asbestos fibers when they were jostled around in a
    packing box, dropped, or stepped on.” Id. (quoting Wiedenbeck v. Searle, 
    385 Ill. App. 3d 289
    , 293, 
    895 N.E.2d 1067
    , 1070 (2008)).
    “While testimony grounded in expert analysis of the known physical facts is welcomed,
    conclusory opinions based on sheer, unsubstantiated speculation should be considered
    irrelevant.” (Internal quotation marks omitted.) Wiedenbeck, 385 Ill. App. 3d at 293. However,
    because Dr. Frank also relied on a welding-rod study from another expert, which the defendant
    did not challenge, we concluded there was no abuse of discretion in the admission of his
    testimony. McKinney, 
    2018 IL App (4th) 170333
     ¶¶ 45-47.
    ¶ 59       Here, Dr. Frank’s testimony was remarkably similar to his testimony in McKinney. When
    addressing the ability of asbestos-containing products to release asbestos fibers, Dr. Frank
    testified that “there’s not a single product I’ve ever come across that has not had the capacity
    to give up fibers when worked with.” He gave as an example “an asbestos cement pipe,” which
    would release asbestos fibers when cut, drilled, beveled, or exposed to the flow of water. Dr.
    Frank concluded that “there isn’t a product that doesn’t have the ability to give up asbestos.”
    ¶ 60       We agree that, alone, such testimony was unsubstantiated and speculative. However, like
    in McKinney, Dr. Frank also provided another basis for his fiber-release opinion. On
    questioning by plaintiffs’ counsel, Dr. Frank testified that in his 40 years of experience, he
    “looked at” cases involving rubber or butyl tape or caulking for windows and doors and
    affirmed that they “can” give off asbestos fibers. Because Dr. Frank’s opinions were supported
    by his experience in working with asbestos and asbestos-containing products similar to the
    ones at issue in this case, we disagree that his fiber-release opinion was speculative or
    unsubstantiated.
    ¶ 61       On review, plaintiffs point to matters outside of Dr. Frank’s testimony that they argue also
    support a finding that Tremco’s products were capable of releasing asbestos fibers. First, they
    note that Dr. Longo, Tremco’s expert, testified he could not rule out the possibility of fiber
    release from Tremco’s products. In particular, he testified that although his testing and analysis
    of Tremco’s products did not detect respirable asbestos fibers, “[n]obody can say that there
    wasn’t one or [two] fibers by chance that got released.” We agree with plaintiffs that such
    testimony supports an inference that Tremco’s asbestos-containing products were capable of
    releasing fibers.
    ¶ 62       Second, plaintiffs further argue that an adverse inference may be drawn from Tremco’s
    failure to produce the results of testing performed on its products by EPI in 2006. They note
    that the jury in this case was instructed pursuant to Illinois Pattern Jury Instructions, Civil, No.
    5.01 (approved July 18, 2014) (hereinafter IPI Civil No. 5.01), which “informs the jury that it
    may infer that certain evidence would have been adverse to a party where that evidence was
    not produced by the party and was within the party’s control.” Lakin v. Casey’s Retail Co.,
    - 13 -
    
    2018 IL App (5th) 170152
    , ¶ 50, 
    107 N.E.3d 904
    . That instruction, also referred to as the
    “missing witness” or “missing evidence” instruction, specifically states as follows:
    “If a party to this case has failed [to offer evidence] [to produce a witness] within
    his power to produce, you may infer that the [evidence] [testimony of the witness]
    would be adverse to that party if you believe each of the following elements:
    1. The [evidence] [witness] was under the control of the party and could have
    been produced by the exercise of reasonable diligence.
    2. The [evidence] [witness] was not equally available to an adverse party.
    3. A reasonably prudent person under the same or similar circumstances would
    have [offered the evidence] [produced the witness] if he believed [it to be] [the
    testimony would be] favorable to him.
    4. No reasonable excuse for the failure has been shown.” IPI Civil No. 5.01.
    ¶ 63       At trial, Milano testified that in 2006, he “mix[ed] up” batches of Tremco’s asbestos-
    containing 440 Tape and caulk (although not Mono caulk) at the request of Tremco’s legal
    counsel and “shipped [the products] off to a lab called EPI” for testing to determine whether
    they released “detectible [sic] asbestos fibers.” Although the testing was done “for the purposes
    of litigation,” it was not done in connection with the present case. Ultimately, the 2006 EPI
    test results were not submitted into evidence in the underlying proceedings, and on appeal,
    Tremco does not challenge the trial court’s decision to instruct the jury pursuant to IPI Civil
    No. 5.01.
    ¶ 64       Plaintiffs assert that “since Tremco conducted the [EPI testing] to determine fiber release
    from its tape and caulk products in preparation for litigation, Tremco’s failure to produce the
    results at trial allowed the jury to infer the results showed Tremco’s products release quantities
    of respirable asbestos fiber.” Before the jury, plaintiffs framed the inference to be drawn from
    the missing evidence in a slightly different way. During their rebuttal closing argument, they
    pointed out that Dr. Longo’s testing “detected *** no chrysotile fibers” and argued the jury
    could draw a contrary “inference” based on the missing EPI testing evidence. In other words,
    the jury could infer that the EPI testing showed the release of chrysotile fibers from Tremco’s
    products. On appeal, Tremco does not dispute the jury could have made this inference and we
    will assume arguendo the inference was permissible. Accordingly, given Dr. Frank’s
    testimony, Dr. Longo’s acknowledgment that he could not rule out fiber release, and the
    allowable adverse inference from the missing EPI testing evidence, we find there was sufficient
    evidence presented from which the jury could determine that Tremco’s 440 Tape and Mono
    caulk were capable of releasing asbestos fibers.
    ¶ 65                                     2. Substantial Causation
    ¶ 66       However, our determination that the record contains sufficient evidence to support a
    finding that Tremco’s products were capable of releasing asbestos fibers does not end our
    inquiry. As Tremco asserts, plaintiffs were also required to present evidence to show that
    decedent was exposed to asbestos from Tremco’s products with “ ‘such frequency, regularity
    and proximity’ ” that the asbestos from those products could be viewed as a substantial factor
    in causing decedent’s mesothelioma.
    ¶ 67       As stated, under the substantial factor test, “the defendant’s conduct is said to be a cause
    of an event if it was a material element and a substantial factor in bringing the event about.”
    - 14 -
    Thacker, 151 Ill. 2d at 354-55. Further, the frequency, regularity, and proximity test has been
    adopted by the supreme court “as a means by which an asbestos plaintiff can prove more than
    minimum contact [with asbestos fibers] to establish that a specific defendant’s product was a
    substantial factor in being a cause in fact of a plaintiff’s injury.” Nolan, 
    233 Ill. 2d at
    432
    (citing Thacker, 
    151 Ill. 2d at 359
    ).
    ¶ 68        In this case, even accepting that Tremco’s 440 Tape and Mono caulk were capable of
    releasing respirable asbestos fibers, the evidence was otherwise lacking with respect to the
    element of substantial factor causation. In particular, there is no evidence in the record showing
    when, and under what circumstances, Tremco’s products released respirable asbestos fibers,
    whether circumstances causing the release of respirable asbestos fibers were the type that
    would have been regularly encountered by decedent when using Tremco’s products, or whether
    the release of fibers from Tremco’s products was anything more than minimal.
    ¶ 69        On appeal, plaintiffs argue the evidence presented satisfied the frequency, regularity, and
    proximity test because decedent worked with Tremco’s asbestos-containing products
    “virtually every working day over his career.” We agree that the record shows decedent worked
    in close proximity with Tremco’s products on a regular and frequent basis. However, it does
    not necessarily follow from such evidence that he also had frequent, regular, and proximate
    contact with respirable asbestos fibers from those products.
    ¶ 70        In Thacker, 
    151 Ill. 2d at 348-49
    , the plaintiff brought suit against the defendant, alleging
    her husband developed cancer and died as a result of his exposure to raw asbestos while
    working in a plant that processed the defendant’s raw asbestos. In addressing the use of fiber
    drift evidence to establish the proximity requirement of the frequency, regularity, and
    proximity test, the supreme court stated that the plaintiff could not “meet her burden of
    production unless and until she [was] able to point to sufficient evidence tending to show that
    [the defendant’s raw] Manville asbestos was actually inhaled by the decedent.” (Emphasis
    added.)

    , 31, 
    572 N.E.2d 320
    , 337 (1991) (acknowledging that the amount of evidence needed to establish the
    regularity and frequency of exposure will differ from case to case based on factors including
    “the tendency of *** asbestos products to release asbestos fibers into the air”); Junge v.
    Garlock, Inc., 
    629 A.2d 1027
    , 1029 (Pa. Super. Ct. 1993) (holding “that [an asbestos] plaintiff
    must present evidence that he inhaled asbestos fibers shed by the specific manufacturer’s
    product”). The Thacker court further stated as follows:
    “We agree *** that even though the plaintiff offered no evidence of where in the
    plant Manville asbestos was processed, the fact that Manville asbestos, once inside the
    plant, necessarily contributed to the dust in the plant air was sufficient to meet the
    proximity requirement, particularly in light of (1) the friable and potent nature of the
    raw asbestos Manville shipped to the plant and (2) testimony, albeit slight, indicating
    that Manville asbestos necessarily generated dust which became part of dust which
    circulated throughout the facility. In effect the appellate court held that, under the facts
    presented, the decedent regularly worked in dangerous proximity to dust generated
    from Manville’s asbestos even if it is assumed that Manville’s asbestos was initially
    processed in areas of the plant removed from where the plaintiff worked and that the
    jury could thereby reasonably infer causation. We agree with this conclusion.”

    - 15 -
    ¶ 71       Here, there is an absence of evidence in the record to show under what circumstances
    Tremco’s products released respirable asbestos fibers such that they could be “actually
    inhaled” by decedent. Id. at 364. Dr. Frank’s testimony that, in his experience, similar products
    were capable of giving off fibers does nothing to explain how such products must be handled
    or manipulated before fibers are released. In short, without more, evidence that decedent was
    exposed to Tremco’s products does not equal evidence that he had frequent, regular, and
    proximate contact with respirable asbestos fibers from those products. In this case, we find it
    is speculative and conjectural to conclude from the evidence presented that respirable asbestos
    fibers were released from Tremco’s products with any frequency or regularity while decedent
    worked in proximity to those products.
    ¶ 72       On appeal, plaintiffs also argue that they were not required to quantify the number of
    asbestos fibers to which decedent was exposed to prove causation. We agree. Nevertheless,
    relevant asbestos case authority dictates that plaintiffs must show more than a de minimis
    exposure to defendant’s asbestos. See Nolan, 
    233 Ill. 2d at 432
     (stating the “frequency,
    regularity and proximity” test was a means by which an asbestos plaintiff can prove more than
    “casual” or “minimum contact” with the defendant’s asbestos); Lohrmann v. Pittsburgh
    Corning Corp., 
    782 F.2d 1156
    , 1162 (4th Cir. 1986) (referring to the frequency, regularity, and
    proximity test as “a de minimis rule since a plaintiff must prove more than a casual or minimum
    contact with the [asbestos] product”). In this instance, plaintiffs’ evidence showed only that
    decedent came into frequent, regular, and proximate contact with Tremco’s products and that
    such products were capable of releasing asbestos fibers. However, plaintiffs presented no
    evidence establishing that the activities engaged in by decedent when working as a window
    glazier with Tremco’s products caused the release of respirable asbestos fibers or that the
    products released asbestos fibers in such amounts that decedent had more than de minimis,
    casual, or “minimum” contact with asbestos from Tremco’s products.
    ¶ 73       Finally, in addressing the issue of causation, the parties disagree as to whether Dr. Frank’s
    causation opinion testimony is contrary to Illinois law. Tremco argues Dr. Frank’s opinions on
    causation are essentially based on an “each and every exposure” theory, wherein any exposure
    to asbestos fibers is a substantial factor in causing asbestos-related disease. To support its
    argument, Tremco cites Krik v. Crane Co., 
    76 F. Supp. 3d 747
    , 749 (N.D. Ill. 2014), an asbestos
    personal injury case wherein the defendants successfully sought to bar the plaintiff from
    presenting expert testimony, including testimony from Dr. Frank, that “each and every
    exposure to asbestos products results in injury to the person so exposed.”
    ¶ 74       In Krik, the plaintiff’s experts were expected to testify “that any exposure to asbestos, even
    the very first one, regardless of dosage is sufficient to cause” asbestos-related disease. Id. at
    752. In particular, it was expected that Dr. Frank would testify that (1) “ ‘any exposure, even
    the first exposure’ ” would be considered a substantial contributing factor and (2) “the first
    exposure, no matter how limited, would be a substantial cause.” Id. The court stated as follows:
    “[The plaintiff] does not offer any expert testimony as to how much asbestos
    exposure he experienced and whether that dosage of exposure was sufficient to cause
    his lung cancer. Rather, he relies upon the ‘Any Exposure’ theory and argues that a
    single exposure to asbestos is enough and every additional exposure contributed as
    well. The primary basis for the ‘Any Exposure’ theory seems to be that [the plaintiff’s]
    experts cannot rule out that a single dose of asbestos causes injury. From this, they
    - 16 -
    conclude that any and all exposure to asbestos is necessarily harmful. [Citation.] This
    is not an acceptable approach for a causation expert to take.” Id. at 752-53.
    See also id. at 753 (citing arguments by the plaintiff’s counsel “ ‘that the cumulative exposure
    is the cause. So that’s [what] Dr. Frank is saying, each exposure is [a] substantial contribution
    to the cumulative total.’ ”).
    ¶ 75        The Krik court noted that Illinois applied “the ‘substantial contributing factor’ test *** to
    the issue of asbestos injury causation” (id. at 751), and stated as follows:
    “Indeed, the controlling case from the Illinois Supreme Court, Thacker, explicitly
    adopted the ‘frequency, regularity, and proximity’ causation test ‘as the rule of law in
    Illinois,’ from a Fourth Circuit case entitled Lohrmann v. Pittsburgh Corning Corp.,
    
    782 F.2d 1156
     (4th Cir. 1986). [Citations.] Lohrmann’s holding, in turn, was based
    upon what the Fourth Circuit termed a ‘de minimis’ rule, that ‘a plaintiff must prove
    more than a casual or minimum contact with the product.’ ” (Emphasis omitted.) Id. at
    753 (quoting Lohrmann, 
    782 F.2d at 1162
    ).
    Accordingly, the court found that the plaintiff’s argument in the case before it was unavailing
    because it was based on the theory “that a single exposure or a de minimis exposure satisfies
    the substantial contributing factor test.” 
    Id.
     The court stated that “it is not that de minimis
    exposure is sufficient, but that more than de minimis exposure is required to prove causation.”
    
    Id.
    ¶ 76        Plaintiffs respond on appeal by arguing that Dr. Frank’s causation opinion in this case was
    not that “each and every exposure” to asbestos was a substantial factor causing asbestos-related
    disease. Rather, they contend that Dr. Frank opined that a disease like decedent’s mesothelioma
    “is caused by that person’s total and cumulative exposure to asbestos” and that “it is
    scientifically impossible to separate out each exposure and say exposure A contributed to the
    person’s total dose but exposure B did not.” Further, they rely on Rost v. Ford Motor Co., 
    151 A.3d 1032
    , 1035 (Pa. 2016), a Pennsylvania Supreme Court case that addressed both the
    “proper application of the ‘frequency, regularity, and proximity’ criteria in asbestos product
    liability litigation” and expert opinion testimony on causation from Dr. Frank.
    ¶ 77        In Rost, there had been a pretrial ruling by the trial court that precluded “any expert from
    offering testimony that ‘each and every breath’ of asbestos may constitute an evidentiary basis
    for the jury to find that the defendant’s product was a substantial cause of mesothelioma.” Id.
    at 1037. At trial, Dr. Frank provided testimony that mesothelioma was a dose-response disease,
    with small amounts of asbestos carrying small risks of developing the disease and larger
    amounts carrying larger risks. Id. at 1039. He also testified that the “causative agent” in
    mesothelioma was “ ‘the series of exposures’ ” and stated that “[a]ll exposures to asbestos
    contribute to the cumulative dose of asbestos, and the cumulative dose causes mesothelioma.”
    Id. Dr. Frank further testified regarding the plaintiff’s specific history in that case, finding that
    he had been exposed to “potentially high amounts [of asbestos] on a daily basis.” Id. at 1040.
    Based on studies he reviewed, he approximated the amount of chrysotile asbestos fibers the
    plaintiff was exposed to in his work. Id. at 1039-40.
    ¶ 78        Additionally, in response to a hypothetical question that detailed the plaintiff’s exposure to
    asbestos, “Dr. Frank testified that it was his opinion *** that [the plaintiff’s] exposure to [the
    defendant’s] products was a ‘significant contributing cause to developing mesothelioma.’ ” Id.
    at 1040. Finally, he opined that if the plaintiff’s only exposures to asbestos was from the
    defendant’s products, those exposures alone “ ‘without any of the ones he had later’ ” would
    - 17 -
    have been enough to say that asbestos from the defendant’s products was a significant
    contributing factor to the plaintiff’s mesothelioma. Id.
    ¶ 79       On review before the Pennsylvania Supreme Court, the defendant challenged Dr. Frank’s
    opinions, arguing they were based on an “each and every exposure” type of theory. Id. at 1043.
    The court stated that “expert testimony based upon the notion that ‘each and every breath’ of
    asbestos is substantially causative of mesothelioma will not suffice to create a jury question on
    the issue of substantial factor causation.” Id. at 1044. Instead, “to create a jury question, a
    plaintiff must adduce evidence that exposure to [the] defendant’s asbestos-containing product
    was sufficiently ‘frequent, regular, and proximate’ to support a jury’s finding that [the]
    defendant’s product was substantially causative of the disease.” Id. Ultimately, it rejected the
    defendant’s challenge to Dr. Frank’s testimony, stating as follows:
    “We must agree with the [plaintiffs] that [the defendant] has confused or conflated
    the ‘irrefutable scientific fact’ that every exposure cumulatively contributes to the total
    dose (which in turn increases the likelihood of disease), with the legal question under
    Pennsylvania law as to whether particular exposures to asbestos are ‘substantial factors’
    in causing the disease. It was certainly not this Court’s intention, [in prior decisions],
    to preclude expert witnesses from informing juries about certain fundamental scientific
    facts necessary to a clear understanding of the causation process for mesothelioma,
    even if those facts do not themselves establish legal (substantial factor) causation. In
    this case, while Dr. Frank clearly testified that every exposure to asbestos cumulatively
    contributed to [the plaintiff’s] development of mesothelioma, he never testified that
    every exposure to asbestos was a ‘substantial factor’ in contracting the disease.
    Instead, by way of, inter alia, the lengthy hypothetical that detailed the entirety of
    [the plaintiff’s] exposure to [the defendant’s] asbestos-containing *** products ***,
    Dr. Frank testified that [the plaintiff’s] actual exposures to asbestos *** [from the
    defendant’s products] was substantially causative of his mesothelioma.” Id. at 1045-
    46.
    The court further noted that Dr. Frank provided testimony that was specific to the plaintiff’s
    history of exposure to asbestos from the defendant’s products, as well as his history of exposure
    from other sources, and that he “testified that the totality of [the plaintiff’s] exposure to
    asbestos [from the defendant’s products], standing alone, was sufficient to have caused [the
    plaintiff’s] mesothelioma, even if there had been no other exposures.” Id. at 1046.
    ¶ 80       In this case, Dr. Frank provided similar testimony to the testimony he provided in Rost
    regarding the “fundamental scientific facts necessary to a clear understanding of the causation
    process for mesothelioma.” Id. at 1045. He asserted that all asbestos fiber types cause
    mesothelioma, that there was a “dose-response” relationship between exposure and
    development of the disease, and that “cumulative exposure, the totality of the exposure” is
    what “causes the disease.” Id. at 1039. Further, unlike in Krik, he did not offer the opinion that
    every exposure to asbestos was a substantial causative factor in the person’s development of
    disease. When considering Dr. Frank’s testimony in total, it is clear that his opinion was that
    each exposure to asbestos contributed to a person’s cumulative exposure and that it was the
    cumulative exposure that caused disease. Accordingly, we do not find that Dr. Frank’s
    testimony was contrary to Illinois law and substantial factor causation as argued by Tremco.
    ¶ 81       However, as noted in Rost, although testimony regarding “certain fundamental scientific
    facts” may be “necessary to a clear understanding of the causation process for mesothelioma,”
    - 18 -
    those same facts do not themselves necessarily establish substantial factor causation. Id. at
    1045. Unlike his opinions in Rost, Dr. Frank’s opinions in this case fell short of demonstrating
    that decedent’s exposure to asbestos from Tremco’s products was a substantial factor in
    causing his mesothelioma. Specifically, Dr. Frank offered almost no testimony or opinions
    regarding decedent’s exposure to asbestos fibers from Tremco’s products, testifying only that
    in his experience similar products “can” release fibers under some unknown set of
    circumstances and in some unknown quantity or concentration. Additionally, when presented
    with a hypothetical question regarding decedent’s work as a glazier with asbestos-containing
    products, Dr. Frank opined only “[t]hat [decedent’s] exposures to asbestos would have caused
    him to develop the mesothelioma that he had that caused his death.” Noticeably absent from
    his testimony was any opinion that exposure to asbestos from Tremco’s products was a
    “substantial” factor in decedent’s development of his disease, particularly when compared to
    his exposure to asbestos from other sources.
    ¶ 82       Here, although we find that Dr. Frank’s “cumulative exposure” testimony was not the
    equivalent of the “each and every exposure” theory, we also find that his opinions failed to aid
    plaintiffs in meeting the substantial factor test under Illinois law. Accordingly, due to the lack
    of evidence showing that decedent’s exposure to respirable asbestos fibers from Tremco’s
    products on a frequent, regular, and proximate basis was a cause in fact in bringing about
    decedent’s mesothelioma, Tremco is entitled to a judgment n.o.v.
    ¶ 83                                    3. Packaging Contamination
    ¶ 84        We note that, on appeal, plaintiffs additionally argue that the jury could have reasonably
    inferred that decedent was exposed to raw asbestos fibers from the boxes in which Tremco’s
    440 Tape and Mono caulk were packaged at its manufacturing facilities. To support this
    contention, plaintiffs rely on testimony from Dr. Longo regarding packaging contamination
    and evidence that Tremco’s Kinsman facility was found to have “high levels” of asbestos fibers
    in its “dust counts.” We disagree with plaintiffs’ arguments on this point.
    ¶ 85        The record reflects that Tremco’s Kinsman facility manufactured roofing materials and not
    the products at issue in this case. Thus, high levels of asbestos fibers in air samples from that
    facility is not evidence that the packaging for Tremco’s 440 Tape and Mono caulk was
    contaminated during the manufacturing process at different facilities. Additionally, Dr.
    Longo’s testimony does not support plaintiffs’ theory of contamination. Dr. Longo stated he
    had no knowledge of “housekeeping” within the Tremco facilities that manufactured the
    products at issue, how raw asbestos was stored by Tremco, or air samples from Tremco’s
    manufacturing facilities. Dr. Longo further testified that he had not tested for contamination
    and stated as follows: “but based on the product itself and how it’s made, it’s not clear to me
    how [contamination] would really happen to any degree.” Given the evidence presented,
    plaintiffs’ assertion that decedent was exposed to raw asbestos fibers from Tremco’s
    manufacturing and packaging process is speculative and unsubstantiated.
    ¶ 86                                       B. Remaining Issues
    - 19 -
    ¶ 87      On appeal, Tremco raises several other issues for review. However, given our finding that
    Tremco is entitled to a judgment n.o.v. based on the lack of evidence of substantial causation,
    we find it unnecessary to address those remaining issues.
    ¶ 88                                      III. CONCLUSION
    ¶ 89      For the reasons stated, we reverse the trial court’s judgment.
