This appeal arises from a pending products liability lawsuit that plaintiffs/appellees Rhonda and Gary Fields filed against a number of manufacturers, suppliers, and sellers of certain asbestos-containing products, including defendants/appellants Union Carbide Corporation (“Union Carbide”), Georgia-Pacific, LLC (“Georgia-Pacific”), CBS Corporation, a Delaware Corporation, f/k/a Viacom, Inc., Successor by Merger to CBS Corporation, a Pennsylvania Corporation, f/k/a Westinghouse Electric Corporation (“CBS-Westinghouse”), and Kuhlman Electric Corporation (“Kuhlman”) (collectively, “Defendants”). The Fieldsеs moved for partial summary judgment on the issue of nonparty fault, seeking to preclude Defendants from presenting the potential fault of numerous nonparty entities for purposes of apportioning Defendants’ potential damages. The trial court granted the Fieldses’ motion. Union Carbide, Georgia-Pacific, and CBS-Westinghouse appeal this ruling in Case No. A11A2025; 1 Kuhlman appeals the same partial summary judgment ruling in Case No. A11A2026. As Kuhlman’s appeal in Case No. A11A2026 presented the same issue for review, this Court granted Kuhlman’s motion to consolidate with Case No. A11A2025. Union Carbide also includes an additional enumeration of error in Case No. A11A2025, in which it challenges the denial of its motion for summary judgment on the grounds that the Fieldses failed to present admissible expert testimony establishing that Union Carbide’s product was the cause of Mrs. Fields’ mesothelioma. For the foregoing reasons, we (1) affirm *555 the grant of the Fieldses’ motion for partial summary judgment and (2) affirm the denial of Union Carbide’s motion for summary judgment.
The standards for reviewing summary judgments are settled. Summary judgment is proper if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law. OCGA § 9-11-56 (c). Thus, to prevail on a motion for summary judgment, the moving party must demonstrate that there is no genuine issue of material fact, so that the party is entitled to judgment as a matter of law.... Where a... [moving party] discharges this burden, the nonmoving party cannot rest on its pleadings, but rather must point to specific evidence giving rise to a triable issue.

Cowart v. Widener,
Moreover, on appeal from the denial or grant of summary judgment, the appellate court is to conduct a de novo review of the evidence to determine whether there exists a genuine issue of material fact, and whether the undisputed facts, viewed in the light most favorable to the nonmoving party, warrant judgment as a matter of law.

Gallagher v. Buckhead Community Bank,
So viewed, the record shows that Mrs. Fields allegedly contracted peritoneal mesothelioma as a result of her childhood exposure to asbestos dust from various sources. These sources included her father’s work clothing — the Fieldses allege that her father was exposed to asbestos-containing products during his 1966 to 1988 employment with Georgia Power Company. Another alleged source of exposure was a joint compound product used in the 1973 construction of Mrs. Fields’ family home. The Fieldses also asserted that Mrs. Fields was exposed to asbestos from her family’s performance of automotive brake work. In their complaint, the Fieldses alleged that Defendants, along with a number of other companies, were responsible for either mining, manufacturing, processing, importing, converting, compounding, selling, or distributing the asbestos-containing products to which Mrs. Fields was exposed.

Fieldses’ Motion for Partial Summary Judgment.
In their respective answers, each Defendant in this case affirmatively pled the defense of nonparty fault, seeking to attribute fault to nonparties to the litigation instead of themselves. Pursuant to a 2005 amendment, Georgia law permits the allocation оf fault to a nonparty for purposes of apportioning damages among the named defendants. See OCGA § 51-12-33 (c) (“In assessing percentages of fault, the trier of fact shall consider the fault of all persons or entities who contributed to the alleged injury or damages, regardless of whether the person or entity was, or could have been, named as a party to the suit.”); see also
Custer v. Terex Corp.,
Here, as required by OCGA § 51-12-33 (d), 2 Defendants filed their respective notices of nonparties at fault. The Fieldses moved for partial summary judgment regarding Defendants’ nonparty defense as it pertained to 51 entities designated in Defendants’ notices. The Fieldses asserted that the Defendants had failed to produce any evidence creating a jury question as to whether these nonparties were responsible for any asbestos-containing products to which Mrs. Fields was exposed. The trial court granted the Fieldses’ motion with respect to 45 specific entities, as well as any other nonparty identified *557 or described in Defendants’ notices of nonparty fault; as a result, the jury will be precluded from assessing the potential fault of these nonparties for the purposes of apportioning damages among Defendants. Defendants appeal the trial court’s ruling only with respect to the following 16 nonparty entities: Georgia Power Company (“Georgia Power”); Ford Motor Company (“Ford”); Genuine Parts Company (“Genuine Parts”); Chrysler LLC (“Chrysler”); General Motors (“GM”); Central Moloney, Inc. (“Central Moloney”); Nehring Electrical Works Company (“Nehring”); Phelps Dodge Cable & Wire (“Phelps Dodge”); Southern States LLC (“Southern States”); Southwire Company (“South-wire”); Asbestоs Corporation Ltd. (“Asbestos Corp.”); Atlas Asbestos (“Atlas”); Johnson Mines; Keasby & Mattison (“Keasby”); Nicolet Industries (“Nicolet”); and Pacific Asbestos.
At the summary judgment stage, the Fieldses, as the moving parties, had the initial burden of piercing Defendants’ affirmative defense, including that of nonparty fault. See
Clay v. Oxendine,
(a) Georgia Power. Defendants assert that it was error for the trial court to grant the Fieldses’ summary judgment motion as to nonparty Georgia Power, asserting that even if Georgia Power owed no legal duty to Mrs. Fields, it could still be at fault for purposes of apportioning damages under OCGA § 51-12-33 (c). We disagree.
Pursuant to OCGA § 51-12-33 (c), “the trier of fact shall consider the fault of all persons or entities who contributed to the alleged injury or damages, regardless of whether the person or entity was, or could have been, named as a party to the suit.” This Court recently applied this stаtute in
Barnett v. Farmer,
(b) Ford and Genuine Parts. Defendants assert that it was error for the trial court to grant summary judgment on their nonparty defense as it pertained to the potential fault of Ford and Genuine Parts. Defendants specifically contend thаt (i) settled entities should be automatically included on the verdict form for purposes of apportioning fault among defendants; or in the alternative, (ii) they presented sufficient evidence to survive summary judgment on their nonparty defense as it pertained to the potential fault of Ford and Genuine Parts.
(i) Pursuant to OCGA§ 51-12-33 (d) (1), the “[n]egligence or fault of a nonparty shall be considered if the plaintiff entered into a settlement agreement with the nonparty or if a defending party gives notice not later than 120 days prior to the date of trial that a nonparty was wholly or partially at fault.” According to Defendants, the languagе of OCGA§ 51-12-33 (d) (1) “singles out settled parties” and requires the automatic consideration of their fault for purposes of apportioning damages among Defendants. Defendants’ interpretation of the statute is erroneous. See
Six Flags Over Ga. v. Kull,
Defendants nevertheless contend that the trial court’s refusal to automatically include settled entities on the verdict form will lead to impermissible double recovery. We disagree. If a settled entity is not included on the verdict form because there was no evidence that the settled entity in fact contributed to the plaintiff’s injury, then it cannot be said that a plaintiff will have rеceived double recovery for that injury. See
Broda v. Dziwura,
(ii) Defendants alternatively contend that they presented sufficient evidence to defeat the Fieldses’ motion for partial summary judgment with respect to Ford and Genuine Parts. Again, we disagree.
As explained in the above subdivision, the fault of a nonparty cannot be considered for the purposes of apportioning damages without some competent evidence that the nonparty in fact “contributed to the alleged injury or damages.” OCGA § 51-12-33 (c). 4 Given this focus on the concept of causation in OCGA § 51-12-33 (c), we turn to the causation standards imposed upon a plaintiff in an asbestos product liability case. Under Georgia law,
the threshold for every theory is proof [i.e., strict liability or negligence] that an injured plaintiff was exposed to asbestos-containing products for which the defendant is responsible. That is, the plaintiff must present evidence that a particular defendant’s asbestos-containing product was used at the job site and that the plaintiff was in proximity to that product at the time it was being used.

Hoffman v. AC&S, Inc., 248
Ga. App. 608, 611 (2) (
In response to the Fieldses’ motion for summary judgment, Defendants point to deposition testimony showing that Mrs. Fields was exposed to brake work performed on her family’s vehicles, and that somе of the vehicles were manufactured by Ford. Despite Mrs. Fields’ lack of knowledge as to whether asbestos was contained in any vehicles or products utilized during her family’s brake work, Defendants rely upon testimony of the Fieldses’ expert, who identified brake work by Mrs. Fields’ father as one source of her asbestos exposure.
Defendants’ designated evidence, however, does not show whether Mrs. Fields was exposed to any Ford vehicles or Genuine Parts products that in fact contained asbestos. See
Hoffman,
supra,
(c) Chrysler and GM. Defendants likеwise assert that there was sufficient evidence, in the form of deposition testimony, to defeat summary judgment on their nonparty defense as it pertained to the potential fault of nonparties Chrysler and GM. We disagree.
Defendants contend that the same evidence offered for the above-mentioned settled entities (Ford and Genuine Parts) establishes that Mrs. Fields was exposed to asbestos through her family’s brake work on vehicles that included those manufactured by Chrysler and GM. As with Ford and Genuine Parts, however, Defendants have not introduced any evidence to show whether the Chrysler and GM vehicles or products to which Mrs. Fields was allegedly exposed in fact contained asbestos. Defendants again rely on an inference that Chrysler and GM products contributed to Mrs. Fields’ mesothelioma; but the evidence does not render less probable the possibility that Mrs. Fields was exposed solely to Chrysler and GM nonasbestos products. Cf.
Adamson,
supra,
(d) Central Moloney, Nehring, Phelps Dodge, Southern States, and Southwire. Defendants assert that they presented sufficient evidence, in the form of allegations contained in the Fieldses’ com *562 plaint and in Mrs. Fields’ sworn information form, 5 to preclude summary judgment on their nonparty defense as it pertained to the potential fault оf nonparties Central Moloney, Nehring, Phelps Dodge, Southern States, and Southwire. We disagree.
Defendants specifically point to the fact that the Fieldses named Central Moloney, Nehring, Southern States, and Southwire in their original complaint, and then alleged in their complaint that all named defendants manufactured or supplied products that exposed Mrs. Fields to asbestos. 6 Defendants also rely upon allegations in Mrs. Fields’ sworn information form that she had been exposed to asbestos emanating from products manufactured by Central Moloney, Nehring, Phelps Dodge, Southern States, and Southwire.
As an initial matter, unverifiеd allegations in a plaintiff’s complaint are generally not evidence for purposes of defeating summary judgment. See
Jones v. City of Willacoochee,
Moreover, even to the extent that Defendants could avail themselves of the foregoing allegations, see OCGA § 24-3-30, this evidence alone was not sufficient to defeat summary judgment on Defendants’ nonparty defense as it pertained to the potential fault of Central Moloney, Nehring, Phelps Dodge, Southern States, and Southwire. Notably, beyond the above-referenced allegations contained in the Fieldses’ complaint and in Mrs. Fields’ sworn information form, Defendants have not оffered any evidence, expert or otherwise, showing that Mrs. Fields’ alleged exposure to these five nonparties’ products in fact contributed to the development of Mrs. Fields’
*563
mesothelioma.

See Butler,
supra,
(e) Asbestos Corp., Atlas, Johnson Mines, Keasby, Nicolet, and Pacific Asbestos. Defendants assert that there was sufficient evidence to defeat summary judgment with respect to their nonparty defense as it pertained to the potential fault of nonparties Asbestos Corp., Atlas, Johnson Mines, Keasby, Nicolet, and Pacific Asbestos. We disagree.
Defendants specifically point to record evidence showing that United States Gypsum Company (“U. S. Gypsum”) manufactured a joint compound product that contained asbestos, andthatMrs. Fields was exposed to asbestos dust from U. S. Gypsum’s joint compound during the construction of her family home. Defendants rely upon U. S. Gypsum’s interrogatory response, which identifies, among other companies, Asbestos Corp., Atlas, Johnson Mines, Nicolet, and Pacific Asbestos as companies known to have been approved suppliers of asbestos to U. S. Gypsum. Defendants contend simply that “[i]f Mrs. Fields was exposed to asbestos contained in the [U. S. Gypsum] joint compound, it is certainly reasonable to infer that she more than likely was exposed to the asbestos supplied by the respective non-parties.” As discussed above, however, “[w]hen a party is relying on inferences to prоve a point, not only must those inferences tend in some proximate degree to establish the conclusion sought, but must also render less probable all inconsistent conclusions.” (Citation and punctuation omitted.)

Union Carbide’s Motion for Summary Judgment.
Mrs. Fields was allegedly exposed to Union Carbide’s Calidria asbestos contained in certain joint compound products used in the 1973 construction of Mrs. Fields’ family home. The record evidence shows that from 1963 through 1985, Union Carbide mined and milled chrysotile asbestos and sold it under the trade name, “Calidria.” According to the record evidence, there are two major families of asbestos fiber — amphibole and serpentine. Chrysotile asbestos is in the serpentine family, and all other types of asbestos minerals are in the amphibole family. The record contains expert testimony reflecting that amphibole asbestos can cause mesothelioma. With respect to chrysotile asbestos, however, Union Carbide argued that there was a lack of scientific foundation showing that it can cause mesothelioma. Union Carbide thus moved under
Daubert v. Merrill Dow Pharmaceuticals,
Union Carbide moved for summary judgment, asserting that the trial court’s Daubert order effectively excluded all of the Fieldses’ scientific evidence of specific causation. The trial court denied Union Carbide’s motion for summary judgment, finding that the scientific evidence appeared to show that chrysotile, when combined with other types of asbestos to which Mrs. Fields was exposed, could cause her *565 mesothelioma. Union Carbide appeals. Concluding that there was suffiсient evidence to create a jury issue as to causation, however, we affirm the trial court’s denial of summary judgment.
A defendant may obtain summary j udgment by showing that there is no evidence sufficient to create a jury issue on at least one essential element of plaintiff’s case.... Causation is an essential element of a toxic tort case, and proof of causation in such cases generally requires reliable expert testimony. Absent reliable expert testimony that exposure to a [company’s] product contributed to the development of [plaintiff’s] mesothelioma, there is insufficient evidence to create a jury issue as to causation.
(Punctuation and footnotes omitted.)
Butler,
supra,
Here, in opposition to Union Carbide’s motion for summary judgment, the Fieldses contended that despite the trial court’s Daubert order, a genuine issue of material fact still remained as to whether chrysotile asbestos, when combined with exposure to other asbestos fibers, can cause mesothelioma. The Fieldses rely on deposition testimony of their expert, opining that exposure to chrysotile and amphiboles together can cause an increased incidence of mesothelioma. The record also reflects affidavit testimony from Union Carbide’s expert stating that mesothelioma is caused by the total dose of asbestos, regardless of the fiber type, that the patient experiences.
Union Carbide attempts to overcome this evidence by arguing that there is no scientific foundation for the Fieldses’ purported “mixed exposure” theory of causation. To the extent that Union Carbide is contending that the Fieldses’ expert testimony on this point did not meet the reliability requirements of OCGA § 24-9-67.1 (b) and
Daubert,
however, the record does not show that Union Carbide raised this objection in the court below or that it was ruled upon by the trial court. Cf.
Mays v. Ellis,
Union Carbide further contends that even assuming a “mixed exposure” causation theory was based on reliable expert testimony, there is no evidence that Mrs. Fields was exposed to amphibole asbestos. In support, Union Carbide points to the testimony of the Fieldses’ expert indicating that, based solely upon his review of the Fieldses’ allegations of exposure and not his own personal knowledge, this case appeared to be one involving chrysotile exposure. However, this testimony does not conclusively demonstrate the absence of a genuine issue of material fact. To the contrary, the Fieldses’ expert also testified that given the various sources of asbestos to which Mrs. Fields was exposed, it was “difficult for [him] to really sort out whether or not there was . . . mixed exposure or chrysotile only еxposure.” “[S]uch contradictions go solely to the expert’s credibility, and are to be assessed by the jury when weighing the expert’s testimony.” (Punctuation and footnote omitted.)
Thompson v. Ezor,
Thus, in light of the expert testimony that exposure to Union Carbide’s product, when combined with other asbestos fibers, could have contributed to Mrs. Fields’ mesothelioma, the Fieldses have demonstrated the existence of a genuine issue for trial as to causation. Therefore, the trial court properly denied Union Carbide’s motion for summary judgment.
Judgments affirmed.
Notes
We note that this Court granted General Electric Company’s motion to withdraw its appeal from Case No. A11A2025.
OCGA§ 51-12-33 (d) provides as follows:
(d) (1) Negligence or fault of a nonparty shall be considered if the plaintiff entered into a settlement agreement with the nonparty or if a defending party gives notice not later than 120 days prior to the date of trial that a nonparty was wholly or partially at fault.
(2) The notice shall be given by filing a pleading in the action designating the nonparty and setting forth the nonparty’s name and last known address, or the best identification of the nonparty which is possible under the circumstances, together with a brief statement of the basis for believing the nonparty to be at fault.
That is, “[t]he notice shall he given by filing a pleading in the action dеsignating the nonparty and setting forth the nonparty’s name and last known address, or the best identification of the nonparty which is possible under the circumstances, together with a brief statement of the basis for believing the nonparty to be at fault.” OCGA § 51-12-33 (d) (2).
If it were otherwise, we agree with the appellees that there would he no limitation on the number of potential nonparties that a trial court would be required to include on the verdict form for purposes of assessing fault under OCGA § 51-12-33 (c).
This sworn information form was included with the Fieldses’ complaint as is required by OCGA§ 51-14-7 in all asbestos claims.
Each of these four entities was eventually omitted as a named defendant in the Fieldses’ subsequent amended complaints.
We note that during the summary judgment hearing, Defendants also pointed to certain portions of Jerry Johnson’s (Mrs. Fields’ father) deposition testimony as additional evidence of fault on the part of nonparties Phelps Dodge and Southwire. However, while the designated testimony shows that Johnson may have used cable manufactured by Phelps Dodge, it does not demonstrate that Phelps Dodge made any asbestos-containing cable that in fact contributed to Mrs. Fields’ mesothelioma. Nor does the designated deposition testimony establish that Southwire manufactured any asbestos-containing cables that in fact contributed to Mrs. Fields’ mesothelioma.
We note that the trial court’s Daubert ruling is not at issue on appeal.
