Kaylo is an asbestos-containing insulation that was manufactured and sold by petitioner, Owens-Illinois, Inc., from 1948 to 1958. In 1958, Owens-Illinois, Inc. conveyed the Kaylo product line to Owens-Corning Fiberglas. Kaylo was generally sold as 50-60 pound blocks which were separated into pieces with hammers or saws. The cutting, *111 fitting, and installation of Kaylo was alleged to have been extremely dusty work.
Respondent, Othello Armstrong, worked first as a laborer and later as a welder on engines and in boiler rooms of various ships being built or repaired at the Bethlehem Steel Corporation shipyards. Armstrong was employed at the shipyards from 1942 to 1963. While there, Armstrong claims he was exposed to thick clouds of asbestos-containing dust which was identified by a witness as Kaylo dust. There is no allegation that Armstrong was exposed to asbestos products after he left the shipyards in 1963.
Respondent, Forrest Wood, was a rigger at a Bethlehem Steel shipyard from 1941 to 1975. As a rigger, Wood assisted other workmen in the removal of equipment and materials from ships. His job included assisting pipe-coverers in the installation and removal of pipe-covering insulation. This work, like that performed by Armstrong, was alleged to have involved exposure to heavy clouds of Kaylo dust.
Armstrong and Wood, along with two other workers not directly involved in this appeal, filed suit in the Circuit Court for Baltimore City against Owens-Illinois and other companies that manufactured, installed, or supplied asbestos-containing insulation products. The plaintiffs’ allegations were based on negligence and strict liability in tort. A jury returned verdicts for Armstrong and Wood against each defendant. The trial court, Judge Clifton J. Gordy, Jr., denied the defendants’ motion for judgment notwithstanding the verdict.
Owens-Illinois and Eagle-Picher Industries, two of the defendants, appealed. The latter’s appeal was stayed after it filed a Title 11 bankruptcy petition in the United States Bankruptcy Court for the Southern District of Ohio, thus making Owens-Illinois the sole defendant seeking review of the judgments. The Court of Special Appeals affirmed the awards.
Owens-Illinois v. Armstrong,
*112 This Court granted Owens-Illinois’ petition for certiorari. We shall address each issue raised by Owens-Illinois, amplifying when necessary the factual scenario presented above.
BUSINESS RECORDS
In 1969, a Bethlehem Steel industrial health engineer was directed by a vice president to conduct an asbestos exposure study and prepare a report on the exposure of both Bethlehem and non-Bethlehem personnel to asbestos-containing dust at Bethlehem’s facilities. The five-page report was offered into evidence by Owens-Illinois as a business record of Bethlehem Steel.
Owens-Illinois contends the Bethlehem study should have been admitted because it showed that, in three “bystander” dust counts taken around employees in the same jobs as Wood and Armstrong working in ship engine rooms where insulation was being installed, no measurable amount of asbestos fibers was detected. Although acknowledging that the report was prepared and maintained in the ordinary course of business, Armstrong and Wood objected to its admissibility. Judge Gordy ruled:
“I don’t have any problem with this [meeting the] business record exception. That does not automatically make an exhibit admissible. It gets over that hurdle, but it is significantly unreliable____ I am not satisfied that the conclusions or the results cited herein are reliable. It is not trustworthy____”
On appeal, Owens-Illinois contends that “once a document has been found to be a business record there is no additional trustworthiness or reliability test unless [in a criminal case] the 6th Amendment is implicated.” We disagree with Owens-Illinois and hold that a trial judge has discretion to exclude a document that meets the technical requirements of a business record when the objecting party persuades the judge that the document lacks the degree of *113 reliability and trustworthiness that business records are ordinarily assumed to possess. 1
In
Palmer v. Hoffman,
“While Palmer has been subject to various interpretations, the most reasonable reading of it is that it did not create a blanket rule of exclusion for accident reports or similar records kept by businesses. Rather, it recognized a discretionary power in the trial court to exclude evidence which meets the letter of the business records exception, but which, under the circumstances, appears to lack the reliability business records are assumed ordinarily to have. The existence of a motive and opportunity to falsify the record, especially in the absence of any coun *114 tervailing factors, is of principal concern. The Federal Rule incorporates this reading of Palmer by permitting admission if the report otherwise complies with the requirements of the rule, ‘unless the source of information or the method or circumstances of preparation indicate lack of trustworthiness.’ ” (Footnotes omitted).
This Court has recognized that, in some instances, business records may be excluded if established to be unreliable or untrustworthy. In
Marine Bank v. Stirling,
“Such a claim would not ordinarily of itself affect the admissibility of an individual ledger, containing the accounts between depositors and the bank, but under such circumstances as are shown in this case there is too much indicating the uncertainty and unreliability of this ledger account to permit it to be used as evidence per se____”
The federal rules of evidence pertaining to the hearsay exception for business records and public records exclude otherwise admissible records if the sources of information or other circumstances “indicate lack of trustworthiness.” Federal Rules of Evidence 803(6) and 803(8).
In
Ellsworth v. Sherne Lingerie, Inc.,
“We also make clear that even though the burden rests upon the party opposing the introduction of a public record to demonstrate the existence of negative factors sufficient to overcome the presumption of reliability, this *115 does not mean that additional evidence will be required in every case to meet that burden. Indicia of unreliability may be contained in the report itself, or may be disclosed by the evidence of the party offering the report.”
The factors that can be utilized by a trial judge in determining whether a business record or a portion of a business record should be excluded for lack of trustworthiness may include such factors as: 1) the purpose for which the record was prepared and any possible motive to falsify including whether the record’s use in prospective litigation was a motive for its preparation,
see Rossi v. Mobil Oil Corp.,
Wood and Armstrong contend that the trial judge was correct in his determination that the disputed “business record” of the asbestos dust study was untrustworthy. The Court of Special Appeals aptly noted that the study was made at the request of one of Bethlehem’s vice-presidents and “[o]n its face, the report appears to be a single or, at most irregular, request.”
The Owens-Illinois product Kaylo was apparently not one of the insulating products in use during the 1969 asbestos dust study, since Owens-Illinois had stopped manufacturing Kaylo eleven years before the study, and we have no description of the asbestos content, if any, of the insulation products that were in use during that study. Further, the trial judge was concerned that the report lacked sufficient specificity as to the methodology used in conducting the study. For the reasons indicated, the trial judge did not err in concluding that the “business record” lacked trustworthiness, and if the 1969 dust study results were to be admitted, the personnel conducting the study would have to be called as witnesses to establish the study’s validity.
Although we sustain the trial judge’s ruling which excluded the “business record” in the instant case because it lacked trustworthiness, we hasten to add that, where a record qualifies as a business record, there is a presumption of trustworthiness, and the objecting party, especially in a civil case, bears a heavy burden in order to exclude an otherwise admissible business record as untrustworthy.
PROXIMATE CAUSE
Owens-Illinois’ next contention is that Armstrong did not prove proximate cause because he “failed to present any evidence that had a warning been given, it would have been heeded.” That contention is based in part on the fact that Armstrong smoked cigarettes for forty years until he quit in the mid-1970’s despite health warnings that were placed *117 on cigarette packages after January 1, 1966. Therefore, according to Owens-Illinois, the lack of a warning on its asbestos product was not the proximate cause of Armstrong’s asbestosis because there is no evidence that he would have heeded that warning.
In analyzing this issue, we must keep in mind that we are being asked to declare as a matter of law that there was insufficient evidence to have submitted this aspect of the case to the jury. Under these circumstances, an appellate court must view the evidence in the light most favorable to the prevailing party below, resolving all conflicts in its favor.
Lehman v. Balto. Transit Co.,
Causation is a necessary element of any strict liability action.
Phipps v. General Motors Corp.,
Owens-Illinois asserts that Armstrong’s “testimony that he smoked for forty years is sufficient evidence to rebut a ‘self-preservation’ presumption.” We disagree and hold that the issue of causation was properly submitted to the jury.
This issue was addressed in
Raney v. Owens-Illinois,
“[A] prediction as to what a worker, alerted to the [asbestos] hazards, would have done is generally within the range of reasonable dispute that makes matters appropri *118 ate for submission to a jury. Evidence that [decedent], who had begun smoking and perhaps had become addicted years before cigarette health warnings appeared, did not stop smoking after such warning ... is, at most, a circumstance for the trier to consider in deciding whether an asbestos warning would have been heeded. Such evidence does not preclude a finding in plaintiffs favor. As [the trial judge] noted, a jury could reasonably conclude that [decedent] would have adjusted his conduct more significantly to asbestos warnings than to cigarette warnings____”
The fact that Armstrong was a heavy smoker who ignored warnings placed on cigarette packages during the last decade of the forty-year period when he smoked is not enough evidence to find as a matter of law that he would have ignored warnings about the dangers of asbestos. We find that there was sufficient evidence for the jury to reasonably conclude Armstrong would have heeded a warning of health hazards from inhalation of asbestos-containing dust from Kaylo products and that Owens-Illinois’ failure to warn was the proximate cause of Armstrong’s asbestosis.
SUBSTANTIAL FACTOR
Wood testified that while assisting workers installing Kaylo pipe-covering, large amounts of dust “would fly like snowflakes” in the air around them. Armstrong testified that he was exposed to dust from pipe-covering material at the shipyard. One of Armstrong’s fellow employees who worked with him for years testified that Armstrong labored near pipe-coverers using Kaylo, which created clouds of dust that completely coated the workers. Expert witnesses testified that the occupational exposure to asbestos was a substantial factor in causing Wood’s and Armstrong’s asbestosis. The trial judge instructed the jury:
*119 “In order for a plaintiff to recover against a particular defendant, certain things must be shown — must be proved by the plaintiffs by a preponderance of the evidence. You must determine whether each plaintiff has proven by a preponderance of the evidence that he has asbestosis, he worked in proximity to and inhaled respirable asbestos fibers from the products of a particular defendant. It must be shown that a product or products manufactured or supplied by that defendant, by a particular defendant was a substantial factor in causing the asbestosis.
If no product manufactured or supplied by a particular defendant was a substantial factor in causing the asbestosis, then that defendant has no responsibility, and the defendant is out right away.
Unless there is a product that was manufactured or supplied by a particular defendant which was a substantial factor in causing the asbestosis, there is no responsibility on the part of that defendant.”
Owens-Illinois contends that the instruction was deficient because it failed to adequately address the special legal meaning of “substantial factor.” The company insists that the jury should have been instructed that, in order for its product to be a substantial factor in causing asbestosis, plaintiffs must show that each of them worked in proximity to Kaylo with enough frequency and with enough regularity for the inhaled fibers from Kaylo to have substantially contributed to their asbestosis. We need not decide whether the requested instruction was correct, since the matter was fairly covered by the instruction actually given.
We believe that in the instant case “substantial factor” was not a mysterious phrase requiring elucidation. The phrase has even been considered as one that is “sufficiently intelligible to furnish an adequate guide in instructions to the jury, and that it is neither possible nor desirable to reduce it to any lower terms.” See W. Page Keeton, Prosser and Keeton on Torts, § 41 at 267 (5th ed. 1984) and authorities cited therein. The plaintiffs’ expert wit *120 nesses obviously understood the phrase “substantial factor” and, no doubt, so did the jury.
In the instant case, especially in light of the expert testimony and the nature and extent of Wood’s and Armstrong’s exposure to Kaylo, the judge was not obligated to further define the concept of substantial factor. “The court need not grant a requested instruction if the matter is fairly covered by instructions actually given.” Maryland Rule 2-520(c).
CAP ON NONECONOMIC DAMAGES
Next Owens-Illinois argues that the Court of Special Appeals erred in holding that Armstrong’s damage award 2 was not subject to reduction by the cap on noneconomic damages in Maryland Code (1974, 1989 Repl.Vol.), Courts & Judicial Proceedings Article § 11-108 (hereinafter the CAP statute). Section 11-108 provides in relevant part:
“(b) Limitation of $350,000 established. — In any action for damages for personal injury in which the cause of action arises on or after July 1, 1986, an award for noneconomic damages may not exceed $350,000.” (Emphasis added.)
Owens-Illinois contends that Armstrong’s cause of action “arose” in September of 1987 when he was first diagnosed as having asbestosis and, therefore, his award for noneconomic damages is subject to the CAP statute. Owens-Illinois argues that the cause of action “arises” at the time the claimant, with due diligence, discovers his injury. Its argument is an extension of this Court’s interpretation of the word “accrues” in the statute of limitations context.
In an asbestos-related injury case, this Court held that “in situations involving the latent development of disease, a plaintiff’s cause of action
accrues
when he ascertains, or through the exercise of reasonable care and diligence should have ascertained, the nature and cause of his inju
*121
ry.”
Harig v. Johns-Manville Products,
Owens-Illinois asks this Court to hold that a cause of action “arises” when it is discovered as opposed to when it comes into existence. In construing the CAP statute, “we assume that the words of the statute are intended to have their natural, ordinary and generally understood meaning in the absence of evidence to the contrary.”
Brodsky v. Brodsky,
We agree with the Court of Special Appeals’ conclusion that a cause of action in negligence or strict liability arises “when facts exist to support each element.”
Armstrong,
Unfortunately, identifying the time at which an asbestos-related injury came into existence is usually not a simple task. Due to the latent nature of asbestos-related disease, experts and courts alike have had difficulty in pinpointing its onset. In
Mitchell v. Maryland Casualty,
“Asbestosis is a disease that occurs in lung tissue as a result of prior asbestos exposure. Although asbestos fibers may be deposited in lung tissue in the course of various occupational exposures, ... the disease of asbestosis occurs only when there has been functional impairment of the lung. The human body has extremely effective defense mechanisms to protect the individual from suffering functional impairment as a result of inhalation of asbestos fibers (or other aerosolized materials). It is only when these defensive responses have produced enough alteration in the structure or physiology of the lung to lead to clinically detectable or symptomatic changes that disease can be said to be present.”
*123
Mitchell,
“As a pathologist I define an ‘injury’ to be the alteration of structure and/or function of a cell, tissue or organ. An ‘injury’ also would include physical or chemical damage to the body which may be detectable only on a microscopic or subclinical level. As a pathologist I define ‘disease’ as the process of reaction and/or repair to injury. In the discussion which follows of the diseases of asbestosis, bronchogenic carcinoma, and mesothelioma, there are injuries to cells, tissues and/or organs and associated diseases caused by exposure to asbestos fibers as described, notwithstanding the fact that the injuries and diseases may not be noticeable to a harmed individual or diagnosable by a clinician until some later point in time.”
Mitchell,
Fortunately, we have the benefit of hindsight in determining whether Armstrong’s cause of action existed prior to 1986. We now know that in 1987 Armstrong was diagnosed as having asbestosis, and we agree with the Court of Special Appeals’ conclusion that “[i]t is inconceivable that Armstrong’s asbestosis came into existence between July 1, 1986 and his medical examination in May 1987.”
Armstrong,
Owens-Illinois’ expert testified that
“asbestosis does not develop immediately after exposure. It takes many, many years, and usually the kind of latency period that we are talking about is probably at the minimum 15 years but more ordinarily 20 or more years. During unusual circumstances less than that could cause the disease.” 5
Based on Owens-Illinois’ expert’s testimony, it is reasonable to assume that Armstrong’s asbestosis took approximately twenty years to develop. Since his exposure began in the early 1940’s, the most reasonable conclusion is that his asbestosis developed at least by the mid-1960’s. Even assuming that the initial damage to Armstrong occurred in 1963, the last year in which he worked in the shipyards, the disease “ordinarily” would have developed by 1983 and under “unusual” circumstances even earlier. The only reasonable conclusion, even viewed in the light most favorable to Owens-Illinois, is that Armstrong had asbestosis prior to July 1,1986. Consequently, we affirm the Court of Special Appeals’ holding that Armstrong’s damage award is not controlled by the cap on noneconomic damages.
DAMAGE SETOFF
In the Armstrong case, the jury returned a compensatory damage verdict against Owens-Illinois, together with defendants Owens-Corning Fiberglas and Eagle-Picher, in the amount of $730,000. In the Wood case, the jury returned a compensatory damage verdict against Owens-Illinois and Owens-Corning Fiberglas in the amount of $657,000. The jury in both cases also determined that Owens-Illinois and Owens-Corning Fiberglas were liable for punitive damages. *125 The punitive damage phase of the trial was to commence the following day.
Subsequent to the verdicts, but before the punitive damage phase, Armstrong and Wood reached a settlement with Owens-Corning Fiberglas. Under the terms of the settlement, Owens-Corning Fiberglas would pay its full pro rata share of each compensatory damage award (one-third of the award in the Armstrong case and one-half of the award in the Wood case) plus an additional amount to settle the punitive damage claims.
In the Armstrong case, Owens-Corning Fiberglas paid $304,166.33, which Owens-Illinois acknowledges represents $60,833 to settle the punitive damage claim and $243,333.33 (one-third of $730,000) to settle the compensatory damage claim. In the Wood case, Owens-Corning Fiberglas paid $410,625, which Owens-Illinois acknowledges represents $82,125 to settle the punitive damage claim and $328,500 (one-half of $657,000) to settle the compensatory damage claim.
At the conclusion of the case, the trial judge reduced the amount of each compensatory damage verdict by the amount that Owens-Corning Fiberglas paid to settle the compensatory damage award. Again, in each case, that amount equalled Owens-Corning Fiberglas’ pro rata share of the award. Owens-Illinois contends that the judge should have reduced the amount of each compensatory damage verdict by the full amount of compensation paid by Owens-Corning Fiberglas, including the punitive damage settlement amount.
The Maryland version of the Uniform Contribution Among Tortfeasors Act, Maryland Code (1957, 1991 Repl.Vol.), Article 50, § 19 (hereinafter UCATA) provides that:
“A release by the injured person of one joint tortfeasor, whether before or after judgment, does not discharge the other tort-feasors unless the release so provides; but reduces the claim against the other tort *126 feasors in the amount of the consideration paid for the release, or in any amount or proportion by which the release provides that the total claim shall be reduced, if greater than the consideration paid.” (Emphasis added).
Section 19 of the UCATA specifically provides that the amount of consideration paid in excess of a
pro rata
share shall reduce the total claim. The purpose of the Act is to prevent double recovery. The amount recoverable from the non-settling defendant when added to the amount recoverable from the settling defendant cannot exceed the plaintiffs verdict.
See Martinez v. Lopez,
We first note that, although Owens-Illinois and Owens-Coming Fiberglas are joint tortfeasors with regard to the compensatory damage claims, they are not joint tortfeasors with regard to punitive damage claims. In contending that each damage award should have been reduced by the entire settlement amount, Owens-Illinois fails to recognize this distinction. Examining the purposes of the UCATA in light of the inherently different functions that punitive and compensatory damages serve, it is apparent that the Act does not envision a reduction of a nonsettling tortfeasor’s liability by another’s settlement of punitive damages.
The UCATA is derived, with the omission of certain sections not here relevant, from the statute promulgated by the Commissioners on Uniform State Laws in 1939 (the 1939 Model Act).
Martinez,
“It is apparent that an injury resulting from the joint tort of two or more persons involves each of them, jointly and severally, in liability for the entire damage. It is equally apparent that this is an instance of a common obligation *127 resting on two or more, the discharge of which by one of them accrues to the advantage of the others.”
In contrast, the award of punitive damages is not an attempt to compensate the injured party for harm suffered, but rather is, as the name implies, punitive in nature. This Court explained in
Embrey v. Holly,
Armstrong and Wood contend, and we agree, that the UCATA does not entitle Owens-Illinois to benefit from the fact that the jury found Owens-Corning Fiberglas liable for punitive damages and that Owens-Corning Fiberglas made a payment to avoid that liability. The settlement here at issue contained two distinct liabilities and reflected settlement of both liabilities separately. Owens-Illinois argues that allowing a plaintiff to apportion his or her settlement between compensatory and punitive damages invites abuse.
In the instant case, to settle the compensatory damage claims, Owens-Coming Fiberglas paid to each plaintiff its full pro rata share of the compensatory damages assessed by the jury. There was no “abuse,” chicanery, or collusion. Instead, Owens-Corning Fiberglas was clearly attempting, in good faith, to separately settle its compensatory damage liability and its punitive damage liability.
Consequently, we affirm the Court of Special Appeals’ judgment that the trial court did not err when it reduced Owens-Illinois’ liability only by the amount of the compensatory settlement.
PUNITIVE DAMAGES
The jury award of punitive damages in the instant case must be reversed. In
Owens-Illinois v. Zenobia,
JUDGMENT OF THE COURT OF SPECIAL APPEALS AFFIRMED IN PART AND REVERSED IN PART. CASE REMANDED TO THAT COURT WITH INSTRUCTIONS TO REMAND THE CASE TO THE CIRCUIT COURT FOR BALTIMORE CITY FOR NEW TRIALS LIMITED TO THE ISSUE OF PUNITIVE DAMAGES. COSTS IN THIS COURT AND IN THE COURT OF SPECIAL APPEALS TO BE PAID TWO-THIRDS BY PETITIONERS AND ONE-THIRD BY RESPONDENTS.

. Armstrong’s expert defined the latency period, as well as the disease, somewhat differently. She testified that asbestosis is active and present from the time that the first fiber gets into the lungs but that often symptoms may not develop for twenty to thirty years.
