[786]*786LAVENDER, J.
T1 Resolution of today's cause requires the Court (1) to ascertain for comparative-negligence purposes the relevance of a plaintiff's negligence when a professional's1 performance is faulted in a negligence action and (2) to decide whether there is competent evidence in the record which would sustain the jury's verdict.
I.
FACTS AND PROCEDURAL HISTORY
[ 2 Steve Stroud, individually, [Stroud] and Stroud Crop, Inc. [SCI] brought an action against Arthur Andersen & Co. [Andersen or defendant], a professional accounting firm, seeking damages for economic injuries allegedly emanating from flawed audits of SCI and Insurance Company of the Prairie States' [ICOPS] financial statements2 The audits were prepared by Andersen. Stroud over a period of years had built ICOPS into one of the larger providers of crop insurance in the United States. SCI was the general managing agent and operator of ICOPS. Both companies were owned primarily by Stroud and their indebtedness was collateral-ized with among other things land and personalty owned by Stroud in an individual capacity.
{3 In the latter part of 1987 SCI-at one of its lenders' insistence-sought to have its December 31, 1987 balance sheet audited. It hired the defendant to perform the required accounting in accordance with generally accepted auditing standards [GAAS].3 Stroud/ SCI assert that the audits for 1987 and later years 4 were negligently prepared by Andersen because (1) a substantial misstatement of SCI's liabilities (in excess of three million dollars) went undetected in them and (2) Andersen failed to identify and communicate to SCI that certain of its internal-accounting mechanisms were "material weaknesses" (as that term is understood under GAAS 5).
T4 Next, plaintiffs assert that it relied upon the flawed audited statements of SCI's financial condition to make certain business decisions which ultimately rendered SCI/ ICOPS unable to sustain economic viability during the 1990's. Lastly, Stroud/SCI allege that Andersen-after becoming aware of the understatement of SCT's labilities-failed to extend to its clients (SCI/ICOPS) the duty of care required by the Code of Professional Conduct for accountants.
5 Andersen defends by asserting (1) that plaintiffs failed to prove by sufficient evidence that its audits of SCI and ICOPS were flawed and (2) that the economic losses suffered by SCI resulted solely from (a) bad management decisions made by Stroud/SCI and (b) SCT's flawed internal accounting procedures.6 Andersen also contests Stroud's [787]*787right as an individual to seek damages for any audit-related injuries. It is Andersen's contention that if the alleged economic injuries were compensable at all, they would be so only to the corporate entity (SCT) and not to its shareholder (Stroud).
16 Before beginning its deliberations the jury was instructed by the trial judge on negligence, wanton and reckless conduct, and punitive damages among other issues. Jury Instruction No. 167 was given at this time which in substance combined what is commonly referred to as the "audit interference rule" 8 with comparative-negligence concepts identified in Oklahoma Uniform Jury Instruction [OUJI-CIV (second)] Instruction No. 9.18. Andersen objects to the trial court's adoption of the audit interference rule asserting that it contravenes the scheme of comparative-negligence enacted in Oklahoma.9
T7 At the conclusion of an eleven-day jury trial judgment was awarded to the plaintiffs on a jury verdict. Both compensatory and punitive damages were awarded. Andersen appealed. The Court of Civil Appeals [COCA] held that Jury Instruction No.16 which adopted the audit interference rule represented a fundamental-law error requiring the judgment's reversal. The case was remanded for a new trial.
18 Appellees sought certiorari which was granted.

STANDARD OF REVIEW
19 When the Court is called upon to review a jury's verdict in an action at law, that verdict is conclusive as to all disputed facts and conflicting statements.10 Where (1) [788]*788there is any competent evidence which reasonably supports the jury's verdict and (2) there are no prejudicial errors shown in the trial court's jury instructions, neither the verdict nor the judgment based thereon will be disturbed on review.11 Further, in the appellate process the Court will not engage in deciding which party produced evidence of the greater weight.12 The decision-where the preponderance of the evidence lies-is left to the jury which is the exclusive judge of the witnesses' credibility.13 Lastly, in assaying the evidence's sufficiency to sustain the judgment the Court views all evidence in the light tending to support the judgment, "together with every reasonable inference deducible therefrom, rejecting all evidence adduced by the adverse party which conflicts with it," 14
[787]*787"As a part of its defense, Defendant first denies that any negligence on its part was the direct cause of the occurrence involved in this lawsuit and any resulting injuries to Plaintiffs. Defendant further contends that if, however, the jury should find that it was negligent to some degree, then it is Defendant's contention that Plaintiffs' own negligence exceeded Defendant's negligence, so as to prevent any recovery by Plaintiffs in this lawsuit.
Under the law you may not find the Plaintiffs were negligent unless you also find that Plaintiffs' negligence contributed to Defendant's failure to preform its audit work. This means, however, that Plaintiffs' conduct must have been unreasonable under the circumstances and interfered with Defendant's ability to perform its duty.
If you find that Plaintiffs were negligent under the circumstances described in the above paragraph, then you are to compare the percentage (0%-100%) of negligence of Plaintiffs, if any, with the percentage (0%-100%) of negligence of Defendant, if any. If you find the Plaintiffs' negligence did not contribute to Defendant's failure to perform its audit work then you may not compare the negligence of the Plaintiffs to the negligence of the Defendant.
The percentage (0%-100%) of negligence you find for each party, under the circumstances described above, should be stated in the appropriate verdict form. The verdict forms have been color-coded to assist you."
[788]*788110 When the Court reviews a claimed fundamental-law error in a jury instruction as to which a timely objection was not made at trial, we apply a plain error rule and require a showing that the instruction, when given, was erroneous as a matter of law and in effect caused injury, ie, was demonstrably prejudicial and not just harmless. To justify reversal the party asserting error bears a high burden of proving that the error was obvious or otherwise seriously affected the judicial proceedings' fairness.
YT11 Lastly, the trial court's denial of prejudgment interest to Stroud/SCI essentially presents a question of law which is reviewed de novo.15 An appellate court has plenary, independent and non-deferential authority to reexamine a trial court's legal rulings.16
III
IT WAS NOT ERROR TO INSTRUCT THE JURY THAT IT COULD COMPARE THE PLAINTIFFS NEGLIGENCE TO ANDERSEN'S ONLY IN-SsOFAR AS IT INTERFERED WITH THE LATTER'S PROFESSIONAL UNDERTAKING (i.e., AUDIT)
1 12 In today's forensic contest it is necessary to understand the context in which the determinative issues arose before their resolution is addressed. It is only when one realizes that the asserted errors relate to separate components [i.e., lability and damages] of the plaintiff's negligence-action that the Court's pronouncement can be fully appreciated.
{13 To establish a prima facie case of negligence Stroud/SCI must prove: (1) that Andersen owed a duty of care-arising from its rendition of professional accounting services-to the plaintiffs, (2) that the duty was breached, and (8) that injury and the resultant damages were directly the result of Andersen's failure to perform its duty.17 The plaintiffs are required to clear two evi-dentiary hurdles to be awarded compensatory damages. First, they must prove that Andersen breached that degree of duty which was owed to them and which resulted in their injury. Then they must adduce evidence establishing the amount of compensatory damages which is their due.
114 Initially, today's pronouncement enunciates the criteria to be used for identifying the scope of a plaintiff's conduct which is relevant when a jury decides whether a defendant's conduct is negligent and caused injury. Then we assess whether the plaintiffs met their burden of proof as to damages. When a jury finds the plaintiff has [789]*789proved a prima facie case of negligence, the plaintiff is entitled to recover those damages which are foreseeable and naturally flow from the defendant's negligent acts.18 In the latter regard it is axiomatic that a defendant is not liable for damages attributable solely to the plaintiff's conduct but instead is only liable for those damages which are proved by the plaintiff to extend from the defendant's established breach-of-duty, i.e., negligence. Simply stated, the latter issue is a question of proving one's damages. Assessment of the compensatory damages resulting or flowing from the defendant's negligent conduct presents a factual question which lies squarely within the jury's province.
A
{15 When a certified public accounting firm is engaged for audit purposes, it is employed to discover "inadvertent errors" in its client's bookkeeping systems and further to protect the client from its own employees' failure to find errors in the company's books and accounting system. Stated in general terms, the auditor is retained to give an opinion whether in conformity with GAAP [Generally Accepted Accounting Principles] the client's financial statements fairly represent its financial position.19
116 A certified public accountant [CPA] owes a different duty of care to his/her client when rendering professional services than the duty of ordinary care which members of society owe to each other. It is Andersen's alleged breach of its professional duty as an auditor which lies at the heart of Stroud/ SCT's negligence claim. Hence, the provision of professional services provides the initial context in which the Court considers SCI's [the plaintiff's] conduct that stands interposed as a defense to Andersen's fault.
117 The seope of Andersen's duty of care owed as a provider of professional accounting services is established not only by the formalized standards adopted by the American Institute of Certified Public Accounts-ie., GAAS and GAAP-but also by the Oklahoma statutory and regulatory provisions which govern the field20 A CPA's duty to his/her client, while not coterminous with those of lawyers and doctors, is certainly comparable in that violation of the recognized rules governing the profession can be used to evidence a breach of duty in a civil action and can also result in professional discipline.21 The Court is mindful of the enhanced obligations and responsibilities owed to the public by a person who dons the mantle of a professional.
T18 At trial Andersen sought to assert a comparative-negligence defense 22 to the allegation that it had committed professional malpractice. In essence Andersen requested the trial fudge to instruct the jury that the plaintiffs' negligent conduct [if causing more than 50% of its damages] could be used to excuse its own negligent performance of professional duties. The trial judge rejected the defendant's position. Rather the trial judge instructed the jury that as it considered whether Andersen breached a duty of care owed to plaintiffs, it could only consider that negligence of the plaintiff which interfered with the defendant's provision of professional services.
[790]*79019 Andersen did adduce at trial evidence from which the jury could have inferred that Stroud/SCI-independent of the audited financial statements-made several negligent business decisions subsequent to Andersen's first audit [e.g., purchase of building and moving corporate headquarters to Ruidoso, New Mexico from Weatherford, OK] which contributed to SCI and ICOPS financial woes. In response the plaintiffs adduced evidence-see Stroud testimony-upon which the jury could have concluded that Stroud/ SCTI's allegedly negligent business decisions were made in reliance upon the flawed financial statements which had been audited by the defendant.
120 Despite the evidentiary conflict over whose conduct caused Stroud/SCT's injury, the jury concluded that plaintiffs did not interfere with Andersen's performance of the respective audits,. Andersen offered no instance where it requested something of the plaintiffs regarding the SCI/ICOPS financial statements which was not provided to the audit staff, Even the auditors who participated in the engagement and testified at trial stated that the plaintiff was very cooperative with all of Andersen's requests.
{21 The trial judge correctly understood that cireumseribing the use of the adduced evidence of plaintiff's own negligence in regard to the first two evidentiary elements [duty and breach] of a prima facie case of negligence did not foreclose Andersen from arguing that the plaintiff's conduct broke the chain of causation as to the injuries/damages which emanated from the defendant's proven negligence.23 Nor did it preclude Andersen from arguing, as it did at trial, that its acts as an auditor did not directly cause the damages for which Stroud/SCI sought compensation.
122 In our quest to determine the relevance of the plaintiff's conduct to a professional-negligence claim, we find the legal analysis of National Surety24 and the Tenth Cireuit of the U.S. Cireuit Court of Appeals' decisions in Fullmer v. Wohlfeiler & Beck25 and Steimer Corp. et al. v. Johnson & Higgins of California26 to be persuasive. There the courts held that an accountant could assert as a defense the plaintiff's own negligent acts when such conduct contributed to the accountant's failure to perform his/her work. As noted by the Tenth Circuit, to hold otherwise would render illusory the notion that an accounting firm is negligent when its performance breaches the duty of care it owes as a professional to the public and causes injury. An accountant cannot defend his/her deficient professional conduct by asserting that its client was also negligent unless the client's conduct can be proven to have interfered with the accountant's provision of professional services. Today's clarification of the proof necessary to establish a prima facie case of professional negligence does not prevent Andersen from asserting-as it did-that the damages for which Stroud/SCI seek compensation did not flow or result from its [the auditors'] conduct. It does prevent the defendant from excusing its lability for professional negligence by interjecting facts into the trial which are unrelated to the issue of its responsibility for negligently-provided professional services.27
123 For the above reasons, we hold that the Jury Instruction No.1628 reasonably states the legal standard to be used when a jury assays a professional's conduct for purposes of determining whether it is negligent.29 Since the contested jury instruction correctly states the status of the law in Oklahoma,30 giving it did not mislead the jury in its assessment whether Andersen's profes[791]*791sional conduct was negligent and does not afford grounds for reversal.31
B
124 Andersen asserts the adduced evidence was insufficient to establish that it caused plaintiff's injury. Defendant also alleges that the evidence which the plaintiffs used to establish the quantum of its damages was speculative. Resolution of the asserted errors requires we review (1) whether the jury was properly instructed on the issue of the required causal nexus between the defendant's conduct and the plaintiffs' injuries/damages necessary to sustain the jury's verdict and (2) whether reasonable inferences can be drawn from the adduced evidence which support the judgment.
T25 An essential element of actionable negligence is that the complained-of conduct be the direct cause of the injury for which compensation is sought.32 Jury Instruction No. 9-almost a verbatim mirror of OUJI-CIV (second) No. 9.6-eorrectly outlines what the plaintiffs must prove in order to establish damages. It provides:
Direct cause means a cause which, in a natural and continuous sequence, produces injury and without which the injury would not have happened. For negligence to be a direct cause it is necessary that some injury to a person or to the property of a person in Plaintiffs situation must have been a reasonably foreseeable result of negligence.
%2%6 In a negligence action a plaintiff is required to adduce evidence which (in the trial judge's opinion) is sufficient (1) to induce a reasonable person to believe that a causal link exists between the defendant's conduct and the resulting injury and (2) to establish the presence of a controverted factual question which should be submitted to the jury.33 If the trial judge-after assessing sufficiency-allows the evidence to reach the jury, the plaintiff bears the burden of persuasion.34 While Oklahoma's extant jurisprudence allows the required nexus between negligent conduct and injury to be proved by cireumstantial evidence, the adduced evidence must have "sufficient probative force to constitute the basis for a legal inference, rather than mere speculation...."35 The conclusion sought to be proved by the plaintiffs must flow with reasonable certainty and probability from the adduced evidence.36 In the latter regard the Court's holding in Hardesty v. Andro Corp.-Webster Div., 1976 OK 129, 555 P.2d 1080, 1034 [quoting Martin v. Griffin Television, Inc., 1916 OK 13, 549 P.2d 85, 92] is insightful. There it held:
"The prohibition of recovery of damages because of uncertainty and too speculative in nature applies to the fact of damage and not to the amount of damage."
The parties do not question that Stroud/SCI were in fact injured. The defendant's issue with the jury's verdict and damage-award more particularly addresses who and/or what caused the economic losses which the plaintiffs experienced and how value was ascribed to the injury. It is against these standards that the Court reviews whether the jury's verdict and damage-award are supported by competent evidence.
11 27 In the present case the jury was required to assess the degree of care utilized by Andersen in meeting its professional obligations to the plaintiffs over approximately a five-year period.37 The case was presented [792]*792to the jury on the plaintiffs' theory of causation which is that Andersen owed them a professional duty-of-care which it breached by rendering flawed audits and that in reliance upon Andersen's defective work product Stroud/SCI made several business decisions which resulted in their injury.38
T28 The record reflects that ICOPS' December 31,1987 financial statement reflected no liability to the Federal Crop Insurance Corporation [FCICl-the federal entity through which ICOPS purchased the crop insurance which it sold. There was also evidence adduced that SCI on January 6, 1988 [one week after SCI/ICOPS's 1987 business year closed] drew a check in the amount of $1,009,472.37 for premiums owed by ICOPS, payable to the federal corporation and that Andersen did not verify how this transaction affected the veracity of SCI's 1987 year-end statement of no Habilities The jury was also presented evidence that after SCI's internal accounting person [Patti Scott] suggested to Andersen in 1998 that an understatement of the Hability owed to the FCIC had existed for several years in the SCI ICOPS intercompany accounts, Andersen-although paid for its audit of SCI's 1992 financial statements-never furnished the same to SCI. Andersen defended its conduct by asserting that the preconditions for the audit's completion were never met by SCI.39
{29 How the jury chose to weigh the various witnesses' testimony is completely within their bailiwick and the Court will not engage in re-weighing the evidence.40 Nonetheless, the adduced evidence (spanning events occurring over the five-year business relationship between SCI/ICOPS and Andersen) constitutes competent evidence-ie., evidence upon which the jury reasonably could have concluded-that (1) an indebtedness was owed to FCIC which was inaccurately reflected in the financial statements of SCI and ICOPS that Andersen audited;41 (2) that the defendant with reckless disregard 42 for its client's welfare failed to exercise that degree of professional judgment required of auditors to discover errors in its clients' accounting systems; and (8) that SCI made several business decisions to its detriment in reliance on the flawed financial statements of its worth. The Court in its review finds that in light of the adduced evidence and the reasonable inferences which can be drawn [793]*793therefrom, there is a competent evidentiary foundation from which the jury could have concluded that Andersen breached the duty of care it owed as a professional auditor to the plaintiffs. The jury's finding-that the defendant breached the duty of care owed to the plaintiffs and thereby caused injury-is supported by competent evidence.
130 At trial it was acknowledged that valuing damages such as those the result of defendant's breach was not an exact science. Nonetheless, the plaintiffs expert 43 testified as to an approximate range of damages by valuing the two companies [SCI and ICOPS] at different times under different scenarios and was vigorously cross-examined by defendant's counsel concerning the same. Oklahoma's jurisprudence is clear that where there is evidence that the plaintiff has suffered injury and some loss, the jury is the proper vehicle for determining what the loss is from the best evidence of which the case's nature admits.44 Here the amount awarded as damages by the jury was approximately three million dollars less than the lower range of damages testified to by the plaintiff's expert. The adduced evidence at trial adequately supports such an award.
131 The Court is also cognizant that the jury found the defendant engaged in wanton and/or reckless misconduct 45 as evidenced by its award of punitive damages.46 The trial court's instruction to the jury as to punitive damages properly comports with the requirements of Oklahoma's extant jurisprudence. Where the defendant's conduct is found to be wanton or reckless, the jury may not compare the plaintiffs' contributory negligence to cither preclude or reduce recovery 47
132 For the above reasons, the plaintiffs' judgment is affirmed both as to proof of liability and the damage-award.
IV
STROUD WAS A FORESEEABLE AND KNOWN RELIER UPON THE AUDITS PREPARED BY ANDERSEN AND, HENCE, IS A PROPER PARTY-PLAINTIFF
{ 33 Defendant objects to the award which the jury made to Steve Stroud individually. Anderson acknowledges that while Stroud is a real party in interest insofar as he is asserting a claim for damages on his own behalf, it owed him no duty since he was never its client. Defendant further asserts that a shareholder cannot assert personal causes for damages occasioned a corporation by breach of a duty owed solely to the company. Andersen's analysis is not persuasive.
T 34 The common law remains in full force in Oklahoma unless a statute explicitly provides to the contrary.48 Further, a presumption favors the preservation of common-law [794]*794rights.49 On the issue of third-party reliance on audited financial statements the common-law principle embraced in the Rest. (Second) of Torts § 552 is determinative. The text of that section is:
One who, in the course of his ... profession ... supplies false information for the guidance of others in their business transactions, is subject to liability for pecuniary loss caused to them by their justifiable reliance upon the information, if he fails to exercise reasonable care or competence in obtaining or communicating the information.... 50
Under the Restatement test an auditor would be liable to a limited group of people embracing (1) those for whose guidance the auditor intended to supply the audit data and (2) those to whom the auditor knows his client intended to supply the audited financial statements.51 The record adequately substantiates satisfaction of the common-law rule of liability. Andersen knew that Stroud used his personal assets to cross-collateralize the indebtedness of both SCI and ICOPS. It is certainly foreseeable that in Stroud's business relationships with these related enterprises he would rely upon the audited financial statements which Andersen prepared.52 It is hard to imagine a more compelling case for application of the § 552 rule. Under the factual cireumstances here present Stroud was not only a proper party plaintiff, he also fell with the ambit of that group of persons to whom Andersen owed a duty of care.
y
STROUD/SCI ARE NOT ENTITLED TO PREJUDGMENT INTEREST UNDER THE PROVISIONS OF 12 0.8.8upp.1997 § 727 (B)
I 35 Plaintiffs' claim that Andersen's negligent conduct injured their "personal rights" thereby entitling them to receive prejudgment interest under the terms of 12 O.S.Supp.1997 § 727 (E).53 The trial court denied their motion for the same.54 The Court does not find § 727(E)'s ambit to be as sweeping as the plaintiffs suggest. Were we to extend the reach of § 727s provisions as requested, our decision would have the practical effect of extending the prejudgment-interest allowance to almost every prevailing party in a tort action. Such a result would eviscerate the legislatively-imposed limitations embodied in § 727s provisions.
136 At common law judgments do not bear interest. Hence, recovery of interest on a judgment must be authorized by statute.[27,28] 136 At common law judgments do not bear interest. Hence, recovery of interest on a judgment must be authorized by statute.55 The injuries of which both SCI and Stroud complain are injuries to business assets, ie., property. When in 1984 the Court first considered whether a negligence claim involving an injury to property was a "personal injury" under the provisions of § 727 then in effect, it held it was not and [795]*795that prejudgment interest was unavailable.56 The statutory amendments to § 727 enacted since then do not persuade the Court that the Legislature intended to extend the Court's earlier definition of "personal" to include injury to property.57 An economic loss emanating from a business venture does not qualify as a personal injury under § 727(E)'s provisions and, hence, does not meet the statutory requirement for an award of prejudgment interest.58 The trial court's denial of prejudgment interest is sustained.
VI
SUMMARY
137 Today's cause calls upon the Court to review the evidentiary process by which a case alleging accountant-malfeasance is presented to a jury. Appellant would have the Court allow it to present evidence of a plaintiffs conduct-occurring before the defendant's engagement as a certified auditor-as a defense to its negligence. Today's pronouncement holds that an accountant may not defend the beach of a duty of care owed to its client by introducing evidence of the client's conduct unless the latter interfered with the defendant's provision of professional services. The above rule is peculiarly relevant to that trial stage where the plaintiff is establishing a prima facie case of actionable negligence.
4 38 The above rule does not preclude the defendant from adducing evidence that the plaintiff's injury did not flow from or was not directly caused by the defendant's conduct. Nor does the announced rule prevent the defendant from asserting supervening or intervening causes, if any there be, which break the chain of causation as to the injury for which the plaintiff is seeking compensation. At trial Andersen did adduce evidence which, if believed by the jury, would have exonerated it of liability for the damages sought by Stroud/SCI. Nonetheless, the jury chose to believe the plaintiffs' evidence and find otherwise.
139 The Court will not re-weigh the evidence in the case before it. A review of the trial transcript discloses that the adduced evidence along with the reasonable inferences which could be drawn from it sufficiently proves not only the fact of the plaintiffs' injury but also the amount of compensatory and punitive damages which were awarded.
"I 40 Upon certiorari previously granted, THE COURT OF CIVIL APPEALS OPINION IS VACATED AND THE DISTRICT COURT JUDGMENT IS AFFIRMED.
