OPINION

BIRD, C.J.

This is an appeal brought by a mortgage loan broker, its affiliated corporations, their principal shareholder, and several of the corporations' officers and directors from a judgment which imposed on them compensatory and punitive damages for breach of duties which were allegedly owed to respondents during the negotiation of a second mortgage loan. Liability of all but one of the appellants is premised on a theory of civil conspiracy. Appellants contend that (1) the record discloses neither the breach of a duty nor the existence of a conspiracy, (2) the trial court erred in concluding that the statute of limitations on respondents' claims was tolled until the "last overt act" in the conspiracy, and (3) punitive damages were excessive.

I

Stockton Home Mortgage Company (Stockton) and Union Home Loans (formerly Union Mortgage Company) (Union) are affiliated corporations engaged in the mortgage loan brokerage business. Stockton operates primarily in northern California, while Union's business is confined to the southern part of the state. Appellant Western Computer Service (Western) is the servicing agent for loans negotiated by Stockton and Union, and appellant Secured Investment Corporation (Secured) is its predecessor. Appellant Irving Tushner (Tushner) is the principal and controlling shareholder of Stockton, Union, Western and Secured. All of the corporations use the business name "Union Home Loans" and are headquartered at the same Los Angeles address. Appellants Esther Flink (Flink) and Elinore Tushner are Tushner's sister and former wife, respectively; each served one or more of the appellant corporations as an officer or director during some or all of the time described in the complaint. Appellant David Marks (Marks) served as president of Secured and Western during a portion of the period at issue.

The essential facts elicited at trial, viewed most favorably to respondents, appear as follows: In 1966, Stockton carried on an extensive television advertising campaign in the Sacramento area. One frequently aired advertisement announced that a $1,000 loan could be paid back completely, principal and interest, for $18 per month. In fact, no such loan was available.

Lured by the advertising claims, respondents, Joseph and Clarice Wyatt, visited Stockton's Sacramento office in November 1966. They sought to retain Stockton's services to negotiate a second mortgage loan on their home for purposes of completing certain home improvements. (Such loans are solicited by mortgage brokers from private, noninstitutional lenders.) Respondents agreed in writing to a loan negotiated by Stockton in the gross amount of $1,325 (including the brokerage fee and closing charges), with payments of $20 per month over 36 months (the 1966 loan). The loan officer orally advised respondents that a "small" balloon payment would be due in the 37th month. (A balloon payment is the amount necessary to amortize principal and interest unpaid at maturity when the prescribed monthly installments have been insufficient to do so.) Because Mr. Wyatt worked seasonally as a construction laborer, respondents specifically inquired of the loan officer about the "grace period" for late installments and were told that a late charge would not be assessed until a payment was 10 days overdue. In response to respondents' further questions about the interest rate, the loan officer quoted a figure of "seven or eight percent."

At a second session, the loan officer produced a "stack" of loan documents, including a retainer agreement, a promissory note, escrow instructions, and a second trust deed. The officer leafed through the documents, briefly describing each and showing respondents where to sign. However, he never pointed out significant provisions of the written agreements or suggested that respondents read them carefully. The loan instruments actually imposed an annual interest rate of 10 percent, allowed only a five-day "grace period" for delinquent payments, and assessed a late charge of 1 percent of the original loan balance for each overdue installment (i.e., $13.25 for each $20 installment). The actual estimated balloon payment, assuming all installments were timely paid, was set forth in the broker's loan statement as $950.70. However, the written loan agreement further provided that monthly installments would be applied first to accrued late charges and interest, rather than to reduction of principal; unreduced principal would thus be deferred until the end of the loan term, accruing additional interest in the interim. All these amounts would be added to the final balloon payment.

Respondents were late with several of their payments on the 1966 loan. Consequently, they faced a balloon payment in March 1970 of $1,340, more than the original loan principal. When respondents asked why the final payment was so high, the late charge and interest provisions of the loan agreement were explained to them. Stockton refused to extend the term of the 1966 loan, and respondents were unable to find other financing. Therefore, in March 1970, they agreed to refinance the unpaid balance through Stockton. A loan (the 1970 loan) was then negotiated in the aggregate principal amount of $2,000, with payments of $45 per month for 36 months; the loan document disclosed an estimated balance due in the 37th month of $816.18. Provisions for interest and late charges were similar to the 1966 loan. Late charges were again assessed during the term of the 1970 loan, and the actual amount demanded by Stockton at maturity (April 1973) was $1,193.16.

After repeated threats of foreclosure on their home, respondents brought suit in July 1973. Their complaint alleged, in substance, that Stockton's misleading television commercials, its misrepresentations about the terms of the 1966 loan, its failure to call respondents' attention to the very unfavorable provisions buried in the loan papers, and its extraction of late charges on the 1970 loan despite the timely payment of all installments, breached the fiduciary duty which is owed by a mortgage loan broker to those who engage its brokerage services. The complaint further alleged that the foregoing resulted from a fraudulent conspiracy engaged in by all of the appellants. Respondents sought compensatory and punitive damages, and imposition of a constructive trust.

The parties stipulated to the issuance of a preliminary injunction staying the foreclosure on respondents' residence pending a final determination of the action, and for so long as monthly installments were paid toward the balance claimed due. In June 1975, two weeks before trial, respondents, finding other financing, repaid the 1970 loan.

To prove the existence of a conspiracy among the appellants, respondents produced, at trial, a former employee who had prepared some of the advertising for the affiliated corporations after 1966. Confirming the use of the misleading television commercials in Sacramento during 1966, this employee testified that appellant Tushner had frequently stated, in meetings attended by all of the other individual appellants except Flink, that it was company policy to pursue late charges vigorously as a prime source of income, and that, if one payment was delinquent, all subsequent payments were also to be considered late. "Late charge" income figures for Secured and Western were introduced at trial for the years 1966 through 1974; the annual amounts increased from approximately $152,000 in 1966 to over $1 million for the two corporations combined in 1971.

The individual appellants were beyond subpoena range and declined to testify at trial. However, respondents read into the record selected portions of appellants' depositions, which described the corporate positions occupied by each and their respective duties. The jury assessed separate awards against each appellant, totalling $25,000 in compensatory damages and $200,000 in punitive damages. The trial court denied appellants' motion for new trial after respondents consented to a reduction of the compensatory award to $1,000.

II

This court must first decide whether the jury verdict is supported by evidence that the appellants did in fact breach fiduciary obligations owed to the respondents. Appellants take the position that their duty of disclosure was fully met when they presented to respondents written loan documents containing all the information required by Business and Professions Code section 10241 Appellants also claim they never charged respondents' account with late charges unless payments were actually overdue.

(1) A mortgage loan broker is customarily retained by a borrower to act as the borrower's agent in negotiating an acceptable loan. All persons engaged in this business in California are required to obtain real estate licenses. (Bus. Prof. Code, §§ 10130 and 10131, subd. (d).) Thus, general principles of agency (Civ. Code, §§ 2228 and 2322, subd. 3) combine with statutory duties created by the Real Estate Law (see Bus. Prof. Code, § 10176, subds. (a), (i)) to impose upon mortgage loan brokers an obligation to make a full and accurate disclosure of the terms of a loan to borrowers and to act always in the utmost good faith toward their principals. "The law imposes on a real estate agent `the same obligation of undivided service and loyalty that it imposes on a trustee in favor of his beneficiary.' [Citations.] This relationship not only imposes upon him the duty of acting in the highest good faith toward his principal but precludes the agent from obtaining any advantage over the principal in any transaction had by virtue of his agency. [Citation.]" ( Batson v. Strehlow (1968) 68 Cal.2d 662, 674-675 [ 68 Cal.Rptr. 589, 441 P.2d 101].) A real estate licensee is "charged with the duty of fullest disclosure of all material facts concerning the transaction that might affect the principal's decision. [Citations.]" ( Rattray v. Scudder (1946) 28 Cal.2d 214, 223 [ 169 P.2d 371, 164 A.L.R. 1356]; see also Realty Projects, Inc. v. Smith (1973) 32 Cal.App.3d 204, 210 [ 108 Cal.Rptr. 71]; Smith v. Zak (1971) 20 Cal.App.3d 785, 792-793 [ 98 Cal.Rptr. 242].)

(2) In the present case, respondents testified they did not read the stack of written loan documents before signing them in 1966. However, respondents did ask the broker about the rate of interest, late payments, and the size of the balloon payment due at the end of the loan period. In response to their questions, respondents received the materially misleading and incomplete information already described in this opinion. ( Ante, pp. 779, 780.) Given this evidence, the jury justifiably concluded that Stockton did not satisfy its fiduciary obligations of disclosure and good faith toward its principal in regard to the 1966 loan.

(3) In the context of insurance policies, this court has long recognized that oral misrepresentations made by an agent to a policyholder are actionable, despite the fact that the written policy itself accurately discloses all terms. "[I]f the agent of the insurer undertakes to advise [a policyholder], . . . it should be the duty of such representative to make no false or misleading statement in that respect." ( Glickman v. New York Life Ins. Co. (1940) 16 Cal.2d 626, 634 [ 107 P.2d 252, 131 A.L.R. 1292].) Other cases have similarly held that the existence of a confidential relationship may justify reliance upon oral misrepresentation of the terms of a contract. (See Security-First Nat. Bank v. Earp (1942) 19 Cal.2d 774, 777 [ 122 P.2d 900]; Kloehn v. Prendiville (1957) 154 Cal.App.2d 156, 161-162 [ 316 P.2d 17].)

(4) There is a second reason why appellants breached their fiduciary obligations toward respondents. In the context of insurance policies, this court has recognized that a fiduciary's duty may extend beyond bare written disclosure of the terms of a transaction to duties of oral disclosure and counseling. The leading case is Raulet v. Northwestern etc. Ins. Co. (1910) 157 Cal. 213 [ 107 P. 292], where this court refused to enforce a clause in a fire insurance policy on furniture which voided the policy if the property was or became encumbered with a chattel mortgage. The court wrote as follows: "`It is a matter almost of common knowledge that a very small percentage of policy-holders are actually cognizant of the provisions of their policies. . . . The policies are prepared by the experts of the companies, they are highly technical in their phraseology, they are complicated and voluminous. . . . The insured usually confides implicitly in the agent securing the insurance, and it is only just and equitable that the company should be required to call specifically to the attention of the policy-holder such provisions as the one before us.'" ( Id., at p. 230, italics added; see also Motor T. Co. v. Great American Indem. Co. (1936) 6 Cal.2d 439, 444 [ 58 P.2d 374]; Glickman v. New York Life Ins. Co., supra, 16 Cal.2d at pp. 631-632.)

The reasoning of these cases applies to transactions with mortgage loan brokers as well. Here, the record discloses that respondents were persons of modest means and limited experience in financial affairs, whose equity in their home was their principal asset. They retained a mortgage loan broker to negotiate for them highly complex loan terms and they may be assumed to have justifiably relied on the latter's expertise. Against such a backdrop, the broker's failure to disclose orally the true rate of interest, the penalty for late payments or the swollen size of the balloon payment clearly constituted breach of the broker's fiduciary obligations. It is noteworthy also that the provisions regarding interest rate, late charges and balloon payment were highly unfavorable to the borrower and yet the broker made no attempt to draw his clients' attention to these matters.

(5) The evidence of actual fraud involved in the 1970 loan is a third reason for finding the appellants guilty of breaching their fiduciary duties. Respondents testified that, mindful of the late charges incurred on the first loan, they made timely payment of all installments until February 1972. Thereafter, payments were made by respondents' disability insurer and the timeliness of those payments is not contested. Nevertheless, appellants charged the Wyatt account on the 1970 loan with several late charges. At trial, they introduced no evidence whatsoever to support their contention that these late charges were proper. The jury once more could reasonably have inferred that the late fees were erroneously imposed and that the error was part of a scheme to defraud respondents.

III

Appellants next contend that there is no substantial evidence of a conspiracy. Appellants stress that no one except Stockton participated in the making of loans to the Wyatts; they further claim that none of them had knowledge of what the employees of Stockton discussed with the Wyatts during the loan transactions.

Appellants mischaracterize what is necessary to support a finding of a civil conspiracy. (6) As long as two or more persons agree to perform a wrongful act, the law places civil liability for the resulting damage on all of them, regardless of whether they actually commit the tort themselves. ( Unruh v. Truck Insurance Exchange (1972) 7 Cal.3d 616, 631 [ 102 Cal.Rptr. 815, 498 P.2d 1063].) "The effect of charging . . . conspiratorial conduct is to implicate all . . . who agree to the plan to commit the wrong as well as those who actually carry it out. [Citations.]" ( Black v. Sullivan (1975) 48 Cal.App.3d 557, 566 [ 122 Cal.Rptr. 119].)

Therefore a plaintiff is entitled to damages from those defendants who concurred in the tortious scheme with knowledge of its unlawful purpose. ( Black v. Sullivan, supra, 48 Cal.App.3d at p. 566.) Furthermore, the requisite concurrence and knowledge "`"may be inferred from the nature of the acts done, the relation of the parties, the interests of the alleged conspirators, and other circumstances."'" ( Chicago Title Ins. Co. v. Great Western Financial Corp. (1968) 69 Cal.2d 305, 316 [ 70 Cal.Rptr. 849, 444 P.2d 481].) Tacit consent as well as express approval will suffice to hold a person liable as a coconspirator. ( Holder v. Home Sav. Loan Assn. (1968) 267 Cal.App.2d 91, 108 [ 72 Cal.Rptr. 704].)

(7) Directors and officers of a corporation are not rendered personally liable for its torts merely because of their official positions, but may become liable if they directly ordered, authorized or participated in the tortious conduct. ( United States Liab. Ins. Co. v. Haidinger-Hayes, Inc. (1970) 1 Cal.3d 586, 595 [ 83 Cal.Rptr. 418, 463 P.2d 770].) Personal liability, if otherwise justified, may rest upon a "conspiracy" among the officers and directors to injure third parties through the corporation. ( Golden v. Anderson (1967) 256 Cal.App.2d 714, 719-720 [ 64 Cal.Rptr. 404]; cf. Gruenberg v. Aetna Ins. Co. (1973) 9 Cal.3d 566, 576 [ 108 Cal.Rptr. 480, 510 P.2d 1032]; Wise v. Southern Pacific Co. (1963) 223 Cal.App.2d 50, 72 [ 35 Cal.Rptr. 652].) (8) Shareholders of a corporation are not normally liable for its torts, but personal liability may attach to them through application of the "alter ego" doctrine (see, e.g., Associated Vendors Inc. v. Oakland Meat Co. (1962) 210 Cal.App.2d 825, 836-837 [ 26 Cal.Rptr. 806]), or when the shareholder specifically directed or authorized the wrongful acts.

(9) When judged against these legal standards, the record supports the jury verdict. First, evidence was introduced at trial to show it was company policy to lure potential borrowers such as respondents into their offices through misleading "bait and switch" advertising. Secondly, on several occasions, appellant Tushner instructed other company officials that "late charges were a great source of income," and that "it had been a policy of the company that if the first payment was late, all the rest of the payments would automatically be late."

The record further discloses a tightly knit, family-oriented business operation under appellant Tushner's close personal control. Tushner owned all or a controlling interest in each of the affiliated corporations. Each of the other individual appellants was an officer or director of one or more of the corporations and each was active in some management position at some time during the years when the conspiracy is alleged to have occurred.

Finally, all the headquarters offices of appellant corporations were in the same building. The first loan papers signed by respondents at Stockton's Sacramento office included a deed of trust containing printed instructions that, when recorded, the deed should be mailed to "Union Home Mortgage Company." Soon after the loan papers were negotiated, a letter was sent to respondents on the letterhead of "Union Home Loans." The letter instructed respondents to mail all payments to Secured Investment Corporation in Los Angeles. The procedure on the second loan was similar, except that payments were mailed to Western Computer Services.

From the above evidence, the jury could reasonably conclude that the breaches of fiduciary duties owed to respondents were undertaken pursuant to established company policies agreed to by each of the appellants.

IV

(10) Appellants contend that the statute of limitations barred respondents' claims. They reason that the three-year period allowed for commencing actions based on fraud (Code Civ. Proc., § 338, subd. 4) had passed, the complaint having been filed six years after the first loan and more than three years after the second loan.

However, the trial judge correctly noted that, when a civil conspiracy is properly alleged and proved, the statute of limitations does not begin to run on any part of a plaintiff's claims until the "last overt act" pursuant to the conspiracy has been completed. ( Schessler v. Keck (1954) 125 Cal.App.2d 827, 832-833 [ 271 P.2d 588].) Here the "last overt act" was appellants' collection a few weeks before trial of the final payment on the 1970 loan. This was the culminating act in the conspiracy to defraud respondents which began with the first tortious act in 1966. Therefore, the trial judge correctly refused to instruct the jury on the statute of limitations.

Appellants would have this court repudiate the "last overt act" doctrine of Schessler v. Keck, supra, 125 Cal.App.2d 827. Schessler derived the doctrine by analogy to the law regarding criminal conspiracies. However, appellants stress, it is only because a criminal conspiracy is itself a punishable and continuing wrong that courts stay the running of the statute of limitations until acts in furtherance of the conspiracy have ceased. This rationale, appellants conclude, is absent in the case of a civil conspiracy, precisely because such a conspiracy is neither a punishable offense standing alone nor a wrong capable of supporting a cause of action by its own weight.

The differences between civil and criminal conspiracies are accurately characterized by appellants. However, they are somewhat beside the point. (11) Statutes of limitations have, as their general purpose, to provide repose and to protect persons against the burden of having to defend against stale claims. ( Telegraphers v. Ry. Express Agency (1944) 321 U.S. 342, 348-349 [88 L.Ed. 788, 792-793, 64 S.Ct. 582]; Shain v. Sresovich (1894) 104 Cal. 402, 406 [38 P. 51].) So long as a person continues to commit wrongful acts in furtherance of a conspiracy to harm another, he can neither claim unfair prejudice at the filing of a claim against him nor disturbance of any justifiable repose built upon the passage of time.

In the present case, for instance, appellants stood accused of continuing their tortious conduct in furtherance of the conspiracy up until — and even after — the filing of the complaint. It was their own conduct that kept the cause of action against them alive. Therefore, no considerations of justice or equity require us to overrule the consistent line of cases that have applied the "last overt act" doctrine to civil conspiracies. ( Bedolla v. Logan Frazer (1975) 52 Cal.App.3d 118, 136-137 [ 125 Cal.Rptr. 59]; Kenworthy v. Brown (1967) 248 Cal.App.2d 298, 301 [ 56 Cal.Rptr. 461]; Schessler v. Keck, supra, 125 Cal.App.2d at pp. 832-833.)

The situation of the respondents, on the other hand, demonstrates the equities served by the "last overt act" doctrine in cases where the fraud is of a continuing nature. There was substantial evidence that appellants were involved in perfecting a scheme whose purpose was to trap respondents on a financial "treadmill" from which they could not escape. Once trapped by the unexpectedly large balloon payment due at the end of the first loan, the respondents found themselves forced to refinance the loan, much as appellants planned. (Efforts to obtain financing from other sources failed.) This permitted the repetitive collection of brokerage fees and late charges from respondents, depleting their resources and moving foreclosure ever closer.

(12) When, as here, the underlying fraud is a continuing wrong, a convincing rationale exists for delaying the running of the statute of limitations. Just as the statute of limitations does not run against an action based on fraud so long as the fraud remains concealed, so ought the statute to be tolled even after the fraud is discovered, for so long as the sheer economic duress or undue influence embedded in the fraud continues to hold the victim in place.

None of the cases relied on by appellants has disapproved the holding in Schessler. In Agnew v. Parks (1959) 172 Cal.App.2d 756 [ 343 P.2d 118], plaintiff alleged a conspiracy to obstruct the orderly prosecution of her malpractice action. However, the face of the complaint made apparent that the last fraudulent act pursuant to the conspiracy occurred more than three years prior to the filing of the pleading. Under these circumstances, the court held that defendants' motion for nonsuit was properly granted. Such a holding, of course, is entirely consistent with Schessler. That case still requires a plaintiff to allege that at least some act pursuant to the conspiracy was still being performed (or was only discovered) within the applicable statute of limitations time period.

That Schessler and Agnew v. Parks are entirely consistent was made clear in Bedolla v. Logan Frazer, supra, 52 Cal.App. 3d at pages 136-137, where the court wrote: "[W]hile the cases support the proposition that a cause of action based on civil conspiracy accrues on the date of the commission of the last overt act in pursuance of the conspiracy ( Schessler v. Keck (1954) 125 Cal.App.2d 827, 832-833 . . .), it is imperative for the plaintiff to allege when the last overt act took place ( Agnew v. Parks, supra)." Since over four years had lapsed between the "last overt act" of the conspiracy and the filing of the complaint, the Bedolla court held that the statute of limitations had run on the cause of action. (See also Kenworthy v. Brown, supra, 248 Cal.App.2d at pp. 301-303; Filice v. Boccardo (1962) 210 Cal.App.2d 843, 846 [ 26 Cal.Rptr. 789]; Teitelbaum v. Borders (1962) 206 Cal.App.2d 634, 637-638 [ 23 Cal.Rptr. 868].)

Finally, it is noteworthy that many of the arguments now urged against the "last overt act" doctrine were presented to the Court of Appeal in Rodriguez v. North American Aviation, Inc. (1967) 252 Cal.App.2d 889 [ 61 Cal.Rptr. 579]. In that case plaintiff charged defendants with conspiring to defame him by publishing defamatory remarks on or about October 9, 1962, then again on October 31, 1963. Plaintiff alleged that he was dismissed from his employment on October 31, 1963, due to these defamations. He filed suit on October 13, 1964. The applicable statute of limitations was one year.

The trial court sustained a demurrer to the entire complaint but the Court of Appeal reversed, relying on the fact that the complaint had been filed within one year of the "last overt act" pursuant to the alleged conspiracy. ( Id., at pp. 893-894.) Thus, even while expressing some doubt about the wisdom of the Schessler case in dicta, the Rodriguez court went on to use the "last overt act" doctrine to judge the sufficiency of the pleading before it.

The Rodriguez court specifically declined to rule on whether the statute of limitations barred recovering damages flowing from the earlier publication, finding it impossible to tell from the complaint whether the plaintiff meant to claim separate damages for each of the two publications. Because the Court of Appeal thus avoided this issue, the Rodriguez case gives little support to appellant's argument that the statute of limitations has run at least on the first of the two loans obtained by the respondents. This court is satisfied that Schessler v. Keck, supra, 125 Cal.App.2d 827 correctly states the law of this state.

V

(13) Appellants' first argument is totally without merit. There was substantial evidence to support the jury's determination that the appellants were guilty of fraud when they conspired to breach their fiduciary duty toward the respondents. Therefore, this was an entirely appropriate case in which to award punitive damages. Fraudulent misrepresentations by real estate brokers have supported punitive damages in the past. (See, e.g., Ward v. Taggart (1959) 51 Cal.2d 736, 743 [ 336 P.2d 534].)

(14) Nor can this court agree that the amount of punitive damages was excessive as a matter of law. As a recent case makes clear, the purpose of punitive damages is to penalize wrongdoers in a way that will deter them and others from repeating the wrongful conduct in the future. ( Neal v. Farmers Ins. Exchange (1978) 21 Cal.3d 910, 928, fn. 13 [ 148 Cal.Rptr. 389, 582 P.2d 980].) "How much" in punitive damages is enough to accomplish this purpose in a particular case is not susceptible of mathematical definition. ( Finney v. Lockhart (1950) 35 Cal.2d 161, 164 [ 217 P.2d 19].)

In the present case, the concealment from borrowers of the company policy regarding "late charges" comprised the core of appellants' wrongful conduct. At trial respondents introduced direct evidence showing that the "late charge" policy was the income-generating motor for Secured and Western, bringing in millions of dollars during the years respondents' loans were being serviced by one of the two companies. The structure of the corporations was such that the jury could reasonably infer that the individual appellants (shareholders, officers or directors of Secured or Western or one of its affiliates) had personally profited from the wrongful conduct. Therefore, an award of $200,000, apportioned among eight corporate and individual appellants, was not excessive. Indeed, the trial judge, in denying appellants' motion for new trial, thought the award showed remarkable restraint. This court agrees. The uncontested evidence shows that the award was much less than the income directly generated by appellants' wrongful conduct.

The judgment is affirmed.

Tobriner, J., Mosk, J., Manuel, J., and Newman, J., concurred.
