Opinion for the Court filed by Circuit Judge WILKEY.
Opinion concurring in part, dissenting in part, filed by Circuit Judge MIKVA.
WILKEY, Circuit Judge.
In December 1980, Philander P. Claxton III organized Bandeirante Corporation, whose principal business was to develop gold mines located in the foothills of the Bolivian Andes. In September 1981, Bandeirante officers Sparkle Diamond and Sharon Smith authorized the sale of virtually all of the corporation’s voting stock for $999,000 in promissory notes tendered by Claxton on behalf of Nilge, Ltda. In August 1982, Claxton called a Bandeirante shareholder’s meeting at the District of Columbia jail, and cast the proxy of Nilge, Ltda., in order to elect a new slate of officers and directors.
The appellants in this case seek to unseat these officers and directors. To do this, they challenge the validity of the corporation’s sale of its stock to Nilge, Ltda. They advance two arguments as to why the sale should be voided. First, they argue that the District of Columbia law specifically forbids corporations to sell stock for promissory notes. Secondly, they claim that Claxton, owing a fiduciary duty to Bandeirante, was obligated to show that the transaction with Nilge was totally fair.
The district court held against the appellants on both arguments. We reverse.
I. Background
The rather unusual facts of this case are somewhat blurred around the edges.1 The record shows, with varying degrees of reliability, references to fabulously rich South American gold mines, a shareholder’s meeting held in a jail cell, a complex web of interlocked business entities, and a struggle for control of one of those business entities, Bandeirante Corporation.
The events giving rise to this case apparently began when Philander P. Claxton III became interested in developing gold mining properties located near the town of Tipuani in Bolivia. According to testimony Claxton gave at trial, an initial investigation of.gold mining opportunities led him to [121]*121one Gilkey, who claimed to hold title to gold mining concessions in Bolivia worth as much as $100,000,000.2
In December 1980 and January 1981 Claxton organized a network of business ventures to exploit the gold mines. The most central of these was Tipuani Limited Partners, which was to serve as the vehicle for the distribution of proceeds from the gold mines. Limited partnerships in Tipuani were sold for cash and notes totaling about $7,000,000.
Claxton formed Bandeirante Corporation to be the general partner for Tipuani.3 Bandeirante was authorized to issue 10,000 shares of Class A voting stock and 10,000 shares of Class B nonvoting stock.4 The 10,000 Class A shares were initially issued for $15,000 to Mr. and Mrs. Donald Loveridge, wealthy individuals residing in Florida who were interested in the Bolivian venture for tax advantages and investment. This stock was repurchased two months later, however, when the Loveridges indicated that they did not wish directly or indirectly to control the operations of the corporation.5 The repurchase of the Loveridge’s stock apparently left no voting stock outstanding.
About half of the Class B nonvoting shares appear to have been sold to Claxton’s wife, Susan Williams, in return for her conveyance to the corporation of a tract of land and a residence in Virginia. Another 3500 Class B shares were sold to the plaintiffs in this case for $350,000.6
The original directors and officers of the corporation were drawn from the law firm Claxton retained to organize Bandeirante.7 These officers and directors were soon replaced with two acquaintances of Claxton’s —Sparkle Diamond, president and treasurer, and Sharon Smith, vice-president and secretary.8 According to uncontroverted testimony given by Claxton at trial, Diamond and Smith were not actively involved in the operation of the corporation, but merely followed such directions as Claxton gave them.9 Claxton did not at this time take a formal management position in the company, but instead was hired as a consultant, receiving a payment of $3,000 per month.10
Claxton completed the network with an off-shore corporation, Nilge, Ltda., which apparently was formed while Claxton was imprisoned at Eglin Air Force Base in January of 1981. (Nilge is Eglin spelled backwards.) 11 Claxton testified at trial that this third business entity was established offshore in order to avoid United States taxes on operations conducted overseas. The record does not state whether Claxton informed the plaintiffs of Nilge’s role in the venture. Claxton testified at trial that he did not hide his involvement in Nilge,12 [122]*122while the plaintiffs argued that Nilge did not exist.13
The precise ownership of Nilge remains something of a mystery, although the trial court found that at the time of trial its shares were held by two Bolivian nationals involved in the gold mining venture.14 The management of Nilge was less obscure, however — at all times relevant to this case, Claxton held a broad power of attorney from Nilge, and directed all of its actions in North America.15
Nilge — rather than Bandeirante — became the vehicle for Claxton’s operation of the mining venture. Tipuani contracted with Nilge for certain management services, paying in part with promissory notes received by Tipuani from its limited partners. Claxton testified at trial that he had performed these management services.16
Reviewing this network of business entities, the district court found that Claxton was “promoting every aspect of the venture.” 17 Claxton initiated and directed the organization of Tipuani, Bandeirante and Nilge; in his role as consultant to Bandeirante and agent of Nilge he oversaw all actions taken by any part of the enterprise.
A major problem soon befell the gold-mining venture — it was learned in the spring of 1981 that the title to the mining property was not clear. A rival group filed a competing claim to the property, and litigation ensued to determine the right owner.18
In the wake of the disclosure that the mining claim might prove worthless, certain of the limited partners began in the summer of 1981 to skip payments on promissory notes owing to Tipuani Limited Partners. Claxton explained at trial that he did not press for payment on these notes, because of the problems surrounding the title to the mines.19
In September of 1981, Nilge used $990,-000 of the promissory notes it had received from Tipuani to purchase Class A shares in Bandeirante that had been returned by the Loveridges. This transaction shifted effective control of the mining operation to Nilge, by making Bandeirante a Nilge subsidiary. Nilge, in turn, was controlled in its North American operations by Claxton. By this complex series of transactions, as the district court found, “Claxton III without expenditure of any of his funds controlled Bandeirante, controlled the management of the mining venture and from time to time adjusted the interests of the parties to suit his purpose.” 20
Soon after the sale of the voting stock to Nilge, Diamond and Smith asked to step down as officers and directors of Bandeirante.21 By January 1982, they were replaced by John Baringer as president, Claxton as secretary, and Michela Perrone as vice-president. The new directors were Claxton, Baringer and Perrone. At that same time, Claxton resigned as consultant to the corporation.22
[123]*123Sometime in early 1982, Claxton was indicted on serious federal felony charges which implicated him in fraudulent conduct not directly related to Bandeirante. Claxton pled guilty to those charges, and was sentenced to a long prison term.23
After his appointment as president, Baringer began raising questions concerning Claxton’s operation of Bandeirante.24 These questions concerned expenditures made by Claxton involving property owned by Claxton’s wife, Susan Williams, and Claxton himself. Baringer contacted both the Loveridges and the appellants, who became aroused by the developing course of events.25 Claxton, meanwhile, objected to Baringer’s operation of Bandeirante.
While confined to the District of Columbia jail awaiting designation to a penitentiary, Claxton acted to remove Baringer from the presidency of the corporation. He used his power of attorney from Nilge to grant himself — through a transaction involving a woman who had no connection with Nilge —Nilge’s proxy.26 Claxton then used the proxy to call a shareholder’s meeting, which he held at his cell in the jail.27 Claxton elected himself, his wife Susan Williams, and his father, Philander P. Claxton, Jr., the president, secretary/treasurer, and vice president, respectively, of Bandeirante. He also elected himself, his father, and George Kloosterhouse (a representative of the Class B stockholders) the directors.28
The appellants seek to undo this election by undoing the sale of the Class A stock to Nilge. They advance two principal theories: that the sale to Nilge is void because promissory notes do not constitute a valid form of payment for the shares, and that the sale is void because Claxton failed to show “the entire fairness and adequacy of the consideration” for thé sale.
II. Treasury Stock Issue
A. The Developing Concept of Treasury Stock
The term “treasury stock” has arisen to describe shares of a corporation which are sold to investors, then reacquired and held by the corporation. The trial court below found that Nilge, Ltda., acquired treasury stock — and that promissory notes are acceptable consideration for treasury stock.29 The case in the trial court thus turned on the treasury stock issue.
1. The Common Law View
For generations, the notion of treasury stock has teased lawyers’ minds. Although the concept has been around for more than a hundred years, commentators and courts have continued to debate the legitimacy and wisdom of the device.
One view — still the rule in Britain — considers it a logical necessity that the shares should be extinguished when reacquired by the corporation, and that any subsequent replacement by newly issued shares. Under this view, the power of the corporation to reacquire shares is a function of its power to reduce its capital. The logic underlying this view was ably expressed by Professor Ballantine in his treatise:
Treasury shares are indeed a masterpiece of legal magic, the creation of something out of nothing. They are no [124]*124longer outstanding shares in the hands of a holder. They are not outstanding because the obligor has become the owner of the obligation____
Treasury shares carry no voting rights as to dividends or distributions. Their existence as issued shares is a pure fiction, a figure of speech to explain certain special rules and privileges as to their reissue. A share of stock, as we have seen, is simply a unit of interest in the corporate enterprise arising from a contract. When the holder of a share surrenders his rights to the corporation it is obvious that the contract is in reality terminated.30
Another view — which at the time the D.C. corporation code was drafted was the majority view in America — held that a corporation could own its own shares. This view held that treasury shares were not extinguished, but remained “in suspended animation — existing, but existing only in a kind of Limbo ____”31 The “suspended animation” language reflected the fact that the corporation was not allowed to exercise certain rights of share ownership, such as the right to vote the shares or receive dividends.32 For various reasons, the sale of treasury stock also was often free from restrictions attached to the sale of newly issued stock, such as par value requirements and pre-emptive rights of purchase.33 States varied widely in the treatment of such shares, however; as one commentator concluded, “There seems to be little agreement as to the precise legal status of treasury shares.” 34
2. The Model Business Corporation Act
Into this state of confusion came the Model Business Corporation Act. The Model Act explicitly recognized the concept of treasury shares, defining them as shares that were “issued but not outstanding.” 35 The Model Act placed restrictions on the ability of a corporation to reacquire its own shares, allowing only funds from surplus to be spent.36 The act allowed the corporation’s directors to resell the shares for such consideration expressed in dollars as they found adequate.37 At the same time, the Model Act forbade the payment for securities by the corporation with certain types of consideration, including promissory notes.38
No draftsmen’s comments exist for the early versions of the Model Act. Individual members of the committee that drafted the Model Act did publish articles which shed some glimmers of light. First, it was claimed that the draftsmen did not intend conceptually to rework corporate law, but only to codify existing law in a form that was more rational and more convenient.39 Secondly, it was the aim of the Model Act’s draftsmen to recognize the existence of treasury shares and to define them “so that the reader will know what [the drafts[125]*125men were] talking about.”40 Finally, and very ambiguously, it was observed that the Model Act “prohibits the issuance of shares for promissory notes and future services.” 41 This language does not reach treasury shares, which are defined as being already issued; the omission of treasury shares could be read as either being deliberate exclusion or careless oversight.
3. The District of Columbia Code
The D.C.Code provisions at issue in this case were derived almost verbatim from the Model Act. “Shares reacquired by the corporation” (the term “treasury stock” was not used) were defined as “issued but not outstanding” shares,42 the corporation’s directors were allowed by § 29-316(c) to resell the shares for such consideration as they found adequate,43 but certain forms of payment (including, again, promissory notes) were specifically excluded as valid payment for the sale of shares by § 29-317.44 The major deviation came in the Code’s requirements for the corporation’s repurchase of its own shares. The D.C. Code employed a more complex formula than did the Model Act, but the thrust of both was similar.45
No extensive legislative history exists for the D.C. Code. The official history that does exist reveals only two rather vague purposes: an intent to bring the antiquated D.C. corporation law somewhat up to date, and an intent to use the Model Act as a guide.46 Additional unofficial legislative history suggests additional legislative concern — especially from the Delaware delegation — that the D.C.Code not be so liberal as to divert revenue from other jurisdictions.47 The legislative history does not address the treasury stock issue at all.
B. Promissory Notes and Treasury Shares
1. § 29-317
The specific provision of the District of Columbia Code at issue — § 29-317 — is am[126]*126biguous in its treatment of the treasury stock issue. The section bans the use of promissory notes as payment for stock. It can be argued that the promissory note restriction applies only to issuances of new stock: it occurs in a provision otherwise devoted to issuances of stock. In support of this approach, it also could be argued that the elimination of the “consideration” requirement for treasury shares in § 29-316 applies not just to the dollar amount of consideration, but to the type of property tendered as consideration.
Conversely, it can be argued that § 29-317 does not restrict the ban on promissory notes to “issuances,” but applies by its terms to all situations where payment is being made to the corporation for shares. In support of this view, it can be noted that the “such consideration as may be fixed” provision of § 29-316(c) follows two other provisions relating to par value, and thus only codifies the common law rule that treasury shares could be sold by the corporation without regard to the stock’s par value. More generally, it could be argued that § 29-316 as a whole aims at establishing the dollar value of the shares for the purpose of establishing the corporation’s stated capital, while § 29-317 is an anti-fraud provision aimed at ensuring that the corporation actually receive a reliable type of consideration for its shares. Treasury shares appear to be excluded from the Model Act’s treatment of stated capital, while no reason exists to think treasury shares should be excluded from the corporation’s anti-fraud provisions.
2. Judicial Interpretation
■The courts have not, to date, resolved the ambiguities left unresolved by the Code and the legislative history. The one case that deals at all with the provisions at issue here establishes only that the restrictions of § 317 apply only to sales of shares by the corporation itself — and not to “an assignment of those shares of stock already issued to and owned by an individual.”48 This result recognizes that the policies underlying § 317 do not apply when the corporate treasury is unaffected.
3. The Structure of the Act
The overall structure of the code does, however, reveal a coherent approach to the treasury stock question. An understanding of the role treasury stock plays in the District of Columbia statute must begin with the concept of stated capital.
Under most corporation statutes, the concept of stated capital plays a key role in the statutory provisions guarding against watered stock. The stated capital represents that portion of the corporation’s assets held within the corporation to provide a “cushion” for creditors should the corporation fail.49 Most corporation statutes— including the one at issue here — establish the stated capital account by reference to the issuance of stock by the corporation. The stated capital normally is at least initially derived from the aggregate par value of all shares sold (with adjustments made, of course, when no-par shares are issued).50
Under those statutes that recognize the concept of stated capital a valid distinction arises between treasury stock and newly issued stock. Most corporation statutes (again, including the one at issue here) forbid corporations to acquire treasury stock when such an acquisition would deplete the stated capital of the corporation. While considerable confusion exists, even today, as to the proper accounting procedures, one point is clear: with rare and minor exceptions,51 any acquisition must be paid for from either capital surplus or earned surplus. A corporation cannot use [127]*127its stated capital to trade in shares of its own stock.52
Given these facts, it would make little sense to insist on issuing treasury stock for par value. The stated capital of the corporation was established when the stock was first issued. That stated capital was not disturbed when the stock was reacquired. Since the stated capital is not involved in the transaction, there is no need to invoke the concept of par value when the stock is resold.
Because of this distinction, the drafters of the older statutes needed a mechanism to distinguish between authorized but unissued stock — whose sale would affect stated capital — and stock issued but not outstanding — whose sale would not affect stated capital. This distinction was made through the treasury share provisions of the Model Act, and similar provisions in those statutes which followed the Model Act.
Treasury stock, then, is a function of the “stated capital” concept.53 Significantly, those modern statutes which have abolished the concepts of stated capital and par value have also abolished the treasury stock concept.54
The function of treasury stock provides the key to the issue before this court. If § 29-317 exists only to protect the stated capital account, it ought not apply to treasury shares since the trading of treasury shares does not affect the stated capital account. On the other hand, if § 29-317 serves a broader purpose which would be affected by treasury share transactions, it should apply to transactions such as the one at issue here.
4. The Purpose of § 29-317
Protecting the stated capital account is clearly one purpose of § 29-317. Promissory notes often prove uncollectable. If they are counted as part of the stated capital, creditors and shareholders who relied on their collectability would be misled.55
At one time — beginning well after the adoption of the statute at issue here — the Model Act would have supported the interpretation that avoiding the watering of new stock was the only purpose of provisions such as § 29-317. A 1960 commentary to the Model Act specified that the Model Act’s provision applied only to newly issued [128]*128stock;56 a 1969 amendment to the Model Act itself placed this interpretation in the statute.57
The district court relied on this subsequent amendment of the Model Act in interpreting the D.C. Code, terming it “legislative history.”58 The district court erred in treating this later commentary — which was issued far too late to benefit the drafters of the District of Columbia statute — as legislative history. This reasoning underlying these subsequent changes can be used, however, much as law review articles are used: as an aid in interpreting an unclear statute. Unfortunately, both the 1960 commentary and the comments explaining the 1969 revision are conclusory in form. No explanation is given as to why the commentators felt treasury stock should be distinguished.
Since then, the Model Act has been revised, and the concepts of both stated capital and treasury stock have been abolished.59 Under the Model Act as it now stands, all sales of stock would be subject to the ban on promissory notes. A proposed Revised Model Act would permit the sale of stock for promissory notes, but impose special disclosure requirements on such sales that are not applicable to other corporate sales of stock.60 The California act — which likewise abolishes the concepts of stated capital and treasury shares — bans outright the sale of stock for unsecured first-party promissory notes.61 Both the Revised Model Act and the California Code suggest that the ban on promissory notes involves interests reaching beyond the sanctity of the stated capital account.
The survival of these provisions reminds that stated capital was never a solitary — or sufficient — bulwark against the dilution of capital. In this century, the nearly universal acceptance of low-par and no-par stocks (and hence the diminishment of “stated capital” as a proportion of the corporation’s economic capital) has eroded its utility as even a partial safeguard; today’s creditors are more likely to look to recent and projected earnings, the total debt-to-equity ratio, the relationship of cash flow to projected income expense, the ratio of current assets (such as short term promissory notes) to current liabilities, and the general [129]*129reputation of the firm. Holding out a small “cushion of capital” at best provides slim returns to creditors, and nothing to equity holders who had hoped to see their investment grow. In the current marketplace, as the drafters of the proposed Revised Model Act recognized, reliance on stated capital more often proves misleading than helpful.62
The gradual erosion of stated capital as a safeguard has highlighted the other safeguards that have been present all along. The most far reaching of these are the fiduciary duties imposed on certain principals of the corporation; the more recent statutes rely ever more heavily on these duties to prevent corporate misconduct.63
As a practical matter, however, the deference shown officers and directors under the “business judgment rule” limits the enforceability of fiduciary duties except in the case of self-dealing or other egregious misconduct. These vague fiduciary duties are therefore supplemented with flat bans against specific kinds of behavior, where a predictive judgment can be made that allowing the practice would more often lead to abuses than to economic gains.
■[1] The D.C. Code’s ban on the sale of stock for promissory notes is such a prophylactic ban. Little of benefit can be expected from allowing the sale of stock for notes. Those notes which promise to be collectable could readily enough be converted to cash,64 while a tremendous temptation exists to transform promissory notes without real value — especially third party promissory notes — into a more valuable asset by transferring them to the corporation for stock. Selling shares for promissory notes doomed to default harms the corporation in numerous ways: by diluting the equity of the other shareholders, by deceiving investors and creditors through falsely inflating the value of the corporation’s assets, and (where, as here, all or almost all of the authorized stock is involved) by causing the corporation to forego other sources of capital.
Another possible rationale for continuing the ban, even where concerns about the stated capital account are not relevant, has to do with the market for corporate control. In some cases, such as the one at issue here, the sale of treasury shares might be sufficient to shift control of the corporation to thepurchaser; in some cases, such as the one at bar, the party purchasing the shares might be a third party friendly to or even associated with embattled incumbent management. Such a transaction — the wisdom of which is cloaked from judicial scrutiny by the business judgment rule — might well suffice to lock in the control enjoyed by incumbent management. When the consideration is merely unsecured promissory notes, this control of the corporation might be acquired without any real assumption of risk by the purchasing shareholder. Such transactions promise to deform the market for control of the corporation, with no offsetting benefits. Given the almost insuperable burdens faced by those who might seek to undo such transactions, the law might well reflect a judgment that a flat ban against such sales would avoid much mischief without frustrating many legitimate transactions.
[130]*130These policies underlying the ban embrace interests beyond the protection of the stated capital account, and so the ban applies to treasury stock as well as to newly issued stock. To exclude treasury shares from this important anti-fraud provision would rule into law an exclusion never embraced by the drafters of the D.C.Code, one which ignores important policies underlying the law.
This case, in addition, presents the paradigm situation for treating the sale of treasury shares like new issues when the anti-fraud provisions of the code are involved. In almost every functional way, the shares involved here are like new shares. The shares involved were sold by error to two investors. As soon as the sale was made, the investors asked that the sale be rescinded. So far as the record shows, the shares may never have been voted. The corporation then held the shares for several months, before selling them to a corporation represented by the promoter of the corporation, who throughout had retained effective control of the company. The shares sold represented almost all the voting stock of the corporation.
In some cases, the sale of treasury shares represents a fairly trivial exchange of assets. In this case, it represents the initial sale of control of the corporation. It makes little sense — factually or legally — to say that the sale at issue here ought to be distinguished from the initial issue of shares.
This opinion in no way abolishes the distinction drawn by the District of Columbia Code between treasury shares and newly issued shares. It simply refuses to draw additional distinctions not drawn by the Code. The nub of the difference between treasury shares and newly issued shares, as both the majority and the dissent recognize, is that the concepts of par value and stated capital do not apply to treasury shares. Since the prohibition at issue here does not depend on those concepts, it applies to both types of stock when the seller is the corporation.
B. Third Party Note Issue
The appellees advance as an alternative argument that even if first party promissory notes are not valid consideration for treasury shares, third party promissory notes are. The appellees claim, “Third party promissory notes are intangible property which is acceptable consideration for the issuance of stock.” 65
The appellees’ argument is flawed in at least two major respects. First, the Code does permit “intangible property” to be tendered for shares of stock, but the Code then specifically excludes “promissory notes” from those forms of property that can be used to buy shares from the corporation.66 This court should look to the more specific provision: intangible property is acceptable, so long as the intangible property involved is not a promissory note.
Secondly, the courts uniformly have rejected the argument propounded by appellees when a statute analogous to the one involved here was applicable.67 In the few other cases facing the same issue, courts have drawn no distinction between unsecured first party promissory notes and third party promissory notes. Those cases that have accepted promissory notes as a valid form of consideration seem invariably to have accepted promissory notes secured by property of real value.68
This approach makes sound common sense. The statutory provisions seek to [131]*131prevent shareholders from being defrauded. It takes little ingenuity to transform a first party promissory note into a third party promissory note; in either case, so long as the notes are unsecured the creditors will quite possibly prove unable to collect on the note. The courts have thus drawn the line between secured notes and unsecured notes, and have paid no attention to how many hands the notes have passed through.
C. Remedy
The plaintiffs sued in both a direct and derivative posture, seeking a declaratory judgment that the sale of stock to Nilge is void. The sale of stock at issue here was illegal. The illegality does not make the sale void from the outset, but merely makes it voidable.69 The defect in the sale would have been cured had the $990,000 purchase price been paid in full.70 While the record suggests strongly that no payment ever was made on any of the notes, the lack of a clear ruling on this point requires us to remand this issue to the district court.
The plaintiffs also seek reinstatement of those directors and officers who held office prior to the challenged shareholders’ meeting at the District of Columbia jail.71 As the district court observed, however, those officers were also elected by Nilge, and so have no more right to office than those they would displace. As the district court found, “a still earlier slate” would be the proper board.72 The [132]*132district court did not specify which earlier slate should take office, an omission of some consequence given the “shambles” in which the district court found Bandeirante’s affairs. Given the record before us, we are in no position to determine which board of directors ought now to take control of the corporation. We remand the issue of determining the proper board to the district court.
Finally, the district court found at the beginning of trial that Nilge was not an indispensable party to this suit.73 This ruling was not challenged on appeal. We can imagine several sound reasons for such a ruling: that Nilge’s sole North American representative was before the court; that the court foresaw a means to devise relief so as to avoid unfair prejudice to Nilge; or that the broad power of attorney granted Claxton by Nilge permitted the court to grant effective relief without unfairly prejudicing Nilge. We choose not to speculate as to the basis for the district court’s order, but merely note that the relief granted by the district court must take into account the fact that Nilge is not a party before the court.
IV. Conclusion
For the foregoing reasons, the judgment of the district court is
Reversed and remanded.
