delivered the opinion of the Court.
This сase calls upon us to determine whether we should fashion a federal common law rule obliging the representative shareholder in a derivative action founded on the Investment Company Act of 1940, 54 Stat. 789, 15 U. S. C. § 80a-l(a) et seq., to make a demand on the board of directors even when such a demand would be excused as futile under state law. Because the scope of the demand requirement embodies the incorporating State’s allocation of governing powers within the corporation, and because a futility exception to demand does not impede the purposes of the Investment Company Act, we decline to displace state law with a uniform rule abolishing the futility exception in federal derivative actions.
*93 1 — 1
The Investment Company Act of 1940 (ICA or Act) establishes a scheme designed to regulate one aspect of the management of investment companies that provide so-called “mutual fund” services. Mutual funds pool the investment assets of individual shareholders. Such funds typically are organized and underwritten by the same firm that serves as the company’s “investment adviser.” The ICA seeks to arrest the potential conflicts of interest inherent in such an arrangement.

v.
Fox,
Petitioner brought this suit to enforce § 20(a) of the Act, 15 U. S. C. § 80a-20(a), which prohibits materially misleading proxy statements.

The complaint was styled as a share
*94
holder derivative action brought on behalf of respondent Cash Equivalent Fund, Inc. (Fund), a registered investment compаny, against Kemper Financial Services, Inc. (KFS), the Fund’s investment adviser. Petitioner alleged that KFS obtained shareholder approval of the investment-adviser contract by causing the Fund to issue a proxy statement that materially misrepresented the character of KFS’ fees. See App. to Pet. for Cert. 90a-91a. Petitioner also averred that she made no precomplaint demand on the Fund’s board of directors because doing so would have been futile. In support of this allegation, the complaint stated that all of the directors were under the control of KFS, that the board had voted unanimously to approve the offending prоxy statement, and that the board had subsequently evidenced its hostility to petitioner’s claim by moving to dismiss. See id., at 92a-93a. The District Court granted KFS’ motion to dismiss on the ground that petitioner had failed to plead the facts excusing demand with sufficient particularity for purposes of Federal Rule of Civil Procedure 23.1. See
The Court of Appeals affirmed the dismissal of petitioner’s § 20(a) claim. See
We granted certiorari,

The derivative form of action permits an individual shareholder to bring “suit to enforce a
corporate
cause of action against officers, directors, and third parties.”
Ross
v.
Bernhard,
“The complaint [in a shareholder derivative action] shall . . . allege with particularity the efforts, if any, made by the plaintiff to obtain the action the plaintiff desires from the directors or comparable authority and, if necessary, from the shareholders or members, and the reasons for the plaintiff’s failure to obtain the action or for not making the effort.”
But although Rule 23.1 clearly
contemplates
both the demand requirement and the possibility that demand may be excused, it does not
create
a demand requirement of any particular dimension. On its face, Rule 23.1 speaks only to the adequacy of the shareholder representative’s pleadings. Indeed, as a rule of procedure issued pursuant to the Rules Enabling Act, Rule 23.1 cannot be understood to “abridge, enlarge or modify any substantive right.” 28 U. S. C. § 2072(b). The purpose of the demand requirement is to “af-for[d] the directors an opportunity to exercise their rеasonable business judgment and ‘waive a legal right vested in the corporation in the belief that its best interests will be promoted by not insisting on such right.’”
Daily Income Fund, Inc.
v.
Fox,
Ill
A
It is clear that the contours of the demand requirement in a derivative action founded on the ICA are governed by
federal
law. Because the ICA is a federal statute, any common law rule necessary to effectuate a private cause of action under that statute is necessarily federal in character. See
Burks
v.
Lasker,
*98
It does not follow, however, that the content of such a rule must be wholly the product of a federal court’s own devising. Our cases indicate that a court should endeavor to fill the interstices of federal remedial schemes with uniform federal rules only when the scheme in question evidences a distinct need for nationwide legal standards, see,
e. g., Clearfield Trust Co.
v.
United States,
Corporation law is one such area. See
Burks
v.
Lasker, supra.
The issue in
Burks
was whether the disinterested directors of a registered investment company possess the power to terminate a nonfrivolous derivativе action founded on the ICA and the Investment Advisers Act of 1940 (IAA). We held that a federal court should look to state law to answer this question. See id, at 477-485. “'Corporations,’” we emphasized, “‘are creatures of state law,’ . . . and it is
*99
state law which is the font of corporate directors’ powers.”
Id,.,
at 478, quoting
Cort
v.
Ash,
Defending the reasoning of the Court of Appeals, KFS argues that petitioner waived her right to the application of anything other than a uniform federal rule of demand because she failed to advert to state law until her reply brief in the proceedings below. We disagree. When an issue or claim is properly before the court, the court is not limited to the particular legal theories advanced by the parties, but rather retains the independent power to identify and apply the proper construction of governing law. See,
e. g., Arcadia
v.
Ohio Power Co.,
The question, then, is whether the Court of Appeals drew its universal-demand rule from an improper source when it disregarded state law relating to the futility exception. To answer that question, we must first determine whether the demand requirement comes within the purview of Burks’ presumption of state-law incorporation, that is, whether the scope of the demand requirement affects the allocation of governing power within the corporation. If so, we must then determine whether a futility exception to the demand requirement impedes the policies underlying the ICA. 6
*101 B
Because the contours of the demand requirement — when it is required, and when excused — determine
who
has the power to control corporate litigation, we have little trouble concluding that this aspect of state law relates to the allocation of governing powers within the corporation. The purpose of requiring a precomplaint demand is to protect the directors’ prerogative to take over the litigation or to oppose it. See,
e. g., Spiegel
v.
Buntrock,
To the extent that a jurisdiction recognizes the futility exception to demand, the jurisdiction places a
limit
upon the directors’ usual power to control the initiation of corporate litigation. Although “jurisdictions differ widely in dеfining
*102
the circumstances under which demand on directors will be excused,” D. DeMott, Shareholder Derivative Actions § 5:03, p. 35 (1987), demand typically is deemed to be futile when a majority of the directors have participated in or approved the alleged wrongdoing, see,
e. g., Barr
v.
Wackman,
36 N. Y. 2d 371, 381,
The futility exception to the demand requirеment may also determine the scope of the directors’ power to terminate derivative litigation once initiated—the very aspect of state corporation law that we were concerned with in
Burks.
In many (but not all) States, the board may delegate to a committee of disinterested directors the board’s power to control corporate litigation. See generally R. Clark,
supra,
§ 15.2.3. Some of these jurisdictions treat the decision of a special litigation committee to terminate a derivative suit as automatically entitled to deference under the “business judgment rule.” See,
e. g., Auerbach
v.
Bennett,
47 N. Y. 2d 619, 631-633,
Superimposing a rule of universal-demand over the corporate doctrine of these States would clearly upset the balance that they have struck between the power of the individual shareholder and the power of the directors to control corporate litigation. Under the law of Delaware and the States that follow its lead, a shareholder who makes demand may not later assert that demand was in fact excused as futile.
Spiegel
v.
Buntrock,
KFS contends that the scope of a federal common law demand requirement need not be tied to the allocation of power to control corporate litigation. This is so, KFS suggests, because a court adjudicating a derivative action based on federal law could sever the requirement of shareholder demand from the standard used to review the directors’ decision to bar initiation of, or to terminate, the litigation. Drawing on the ALI’s Principles of Corporate Governance, the Court of Appeals came to this same conclusion. See
We reject this analysis. Whatever its merits as a matter of legal reform, we believe that KFS’ proposal to detach the demand standard from the standard for reviewing board action would require a quantum of federal common lawmaking that exceeds federal courts’ interstitial mandate. Under state law, the determination whether a derivative representative can initiate a suit without making demand typically is made at the outset of the litigation and is based on the application of the State’s futility doctrine to circumstances as they then exist. D. DeMott,
swpra,
§5:03, at 31. Under KFS’ proposal, federal courts would be obliged to develop a body of principles that would replicate the substantive effect of the State’s demand futility doctrine but that would be applied
after
demand has been made and refused. The ALI, for example, has developed an elaborate set of standards that calibrates the deference afforded thе decision of the directors to the character of the claim being asserted by the derivative plaintiff. See ALI, Principles of Corporate Governance §7.08 (Tent. Draft No. 8, Apr. 15, 1988);
id.,
§7.08, Comment c, p. 120 (noting that Principles “dra[w] a basic distinction between the standard of review applicable to actions that are founded on a breach of the duty of care and the standard of review applicable to actions that are founded on a breach of the duty of loyalty”).
8
Whether a federal court adopts
*105
the ALPs standards wholesale or instead attempts to devise postdemand review standards more finely tuned to the distinctive allocation of managerial decisiоnmaking power embodied in any given jurisdiction’s demand futility doctrine, KFS’ suggestion would impose upon federal courts the very duty “to fashion an entire body of federal corporate law” that
Burks
sought to avoid.
Such a project, moreover, would necessarily infuse corporate decisionmaking with uncertainty. For example, insofar as Delaware law does not permit a shareholder to make a demand and later to assert its futility, receipt of demand makes it crystal, clear to the directors of a Delaware corporation that the decision whether to commit the corporation to litigation lies solely in their discretion. See
Spiegel
v.
Buntrock, supra,
at 775. Wеre we to impose a universal-demand rule, however, the directors of such a corporation could draw no such inference from receipt of demand by a shareholder contemplating a federal derivative action. Because the entitlement of the directors’ decision to deference in such a case would depend on the court’s application of independent review standards somewhere down the road, the directors could do no more than speculate as to whether they should assess the merits of the demand themselves or instead incur the time and expense associated with forming a spеcial litigation committee; indeed, at that stage, even the deference due the decision of such a committee would be unclear. The directors’ dilemma would be especially acute if the shareholder were proposing to join state-law and federal claims, see
RCM Securities Fund, Inc.
v.
Stanton,
Finally, in our view, KFS overstates the likely judicial economies associated with a federal universal-demand rule when coupled with independent standards of review. Requiring demand in all cases, it is true, might marginally enhance the prospect that corporate disputes would be resolved without resort to litigation; however, nothing disables the directors from seeking an accommodation with a representative shareholder even after the shareholder files his complaint in an action in which demand is excused as futile. At the same time, the rule proposed by KFS is unlikely to avoid the high collateral litigation costs associated with the demand futility doctrine. So long as a federal court endeavors to reproduce through independent review standards the allocation of managerial power embodied in the demand futility doctrine, KFS’ universal-demand rule will merely shift the focus of threshold litigation from the question whether demand is excused to the question whether the directors’ decision to terminate the suit is entitled to deference under federal standards. Under these circumstances, we do not view the advantages associated with KFS’ proposal to be sufficiently
*107
apparent to justify replacing “the entire corpus of state corporation law” relating to demand futility. See
Burks
v.
Lasker,
C
We would nonetheless be constrained to displace state law in this area were we to conclude that the futility exception to the demand requirement is inconsistent with the policies underlying the ICA. See id., at 479-480. KFS contends that the futility exception does impede the regulatory objectives of the statute. As KFS notes, thе requirement that at least 40% of the board of directors be financially independent of the investment adviser constitutes “[t]he cornerstone of the ICA’s effort to control conflicts of interest within mutual funds.” Id., at 482. KFS argues that the futility exception undermines the “watchdog” role assigned to the independent directors, see id., at 484-485, because empowering a shareholder to institute corporate litigation without the permission of the board allows the shareholder to “usurp” the independent directors’ managerial oversight responsibility. See Brief for Respondent KFS 40.
We disagree. KFS’ argument misconceives the means by which Congress intended independent directors to exercise their oversight function under the ICA. As we emphasized in
Burks,
the ICA embodies a congressional expectation that the independent directors would “loo[k] after the interests of the [investment company]” by “exercising the authority granted to them
by state law.”
KFS also-'ignores the role that the ICA clearly envisions for shareholders in protecting investment companies from conflicts of interest. As we have pointed out, § 36(b) of the ICA expressly provides that an individual shareholder may bring an action on behalf of the investment company for breach of the investment adviser’s fiduciary duty. 15 U. S. C. §80a-35(b). Congress added § 36(b) to the ICA in 1970 because it concluded that the shareholders should not have to “rely solely on the fund’s directors to assure reasonable adviser fees, notwithstanding the increased disinterestedness of the board.”

v.
Fox,
IV
We reaffirm the basic teaching of Burks v. Lasker, supra: where a gap in the federal securities laws must be bridged by a rule that bears on the allocation of governing powers within the corporation, federal courts should incorporate state law into federal common law unless the particular state law in question is inconsistent with the policies underlying the federal statute. The scope of the demand requirement under state law clearly regulates the allocation of corporate governing powers between the directors and individual shareholders. Because a futility exception to demand does not impede the regulatory objectives of the ICA, a court that is entertaining a derivative action under that statute must apply the *109 demand futility exception as it is defined by the law of the State of incorporation. The Court of Appeals thus erred by fashioning a uniform federal common law rule abolishing the futility exception in derivative actions founded on the ICA. 10
Accordingly, the judgment of the Court of Appeals is reversed, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
Notes
Section 20(a) states:
“It shall be unlawful for any person, by use of the mails or any means or instrumentality of interstate commerce or otherwise, to solicit or to permit the use of his name to solicit any proxy or consent or authorization in respect of any security of which a registered investment company is the issuer in contravention of such rules and regulations as the [SEC] may prescribe as necessary or appropriate in the public interest or for the protection of investors.” 15 U. S. C. §80a-20(a).
SEC regulations require proxy statements issuеd by a registered investment company to comply with the proxy statement rules promulgated under the Securities Exchange Act of 1934. See 17 CFR § 270.20a-l(a) *94 (1990). The latter rules prohibit materially misleading statements. See § 240.14a-9.
The ALI’s proposal would excuse demand “only when the plaintiff makes a specific showing that irreparable injury to the corporation would otherwise result.” Principles of Corporate Governance § 7.03(b). The Court of Appeals did not specifically address this aspect of the ALI’s proposal, although the court did reject the possibility that “exigencies of time” would warrant dispensing with demand.
The Court of Appeals also revеrsed the District Court’s conclusion that petitioner could not sue under § 36(b) of the Act, 15 U. S. C. § 80a-35(b), because she was not an adequate shareholder representative under Rule 23.1. See
We have never addressed the question whether § 20(a) creates a shareholder cause of action, either direct or derivative. The SEC, as
ami-cus curiae,
urges us to hold that a shareholder may bring suit under § 20(a) but only on his own behalf. The pаrties did not litigate this question in the Court of Appeals, and because that court disposed of petitioner’s claim on different grounds, it declined to address whether § 20(a) creates a derivative action. See
We do not meаn to suggest that a court of appeals should not treat an unasserted claim as waived or that the court has no discretion to deny a party the benefit of favorable legal authorities when the party fails to comply with reasonable local rules on the timely presentation of arguments. See generally
Singleton
v.
Wulff,
KFS argues that
Burks
is not controlling because this Court established a uniform, federal common law demand requirement in
Halves
v.
Oakland,
All States require that a shareholder make a precomplaint demand on the directors. See D. DeMott, Shareholder Derivative Actions § 5:03, p. 23 (1987); id., at 65, n. 1 (Supp. 1990). Only a few States, however, have adopted a universal-demand rule. See Fla. Stat. Ann. § 607.07401(2) (Supp. 1991); Ga. Code Ann. § 14-2-742 (1989); Mich. Comp. Laws Ann. § 450.1493a(a) (1990).
The American Bar Association’s Model Business Corporation Act likewise abolishes the futility exception to demand. See Model Business Corporation Act § 7.42(1), reprinted in 45 Bus. Law. 1241, 1244 (1990). And like the ALI’s Principles of Corporate Governаnce, the Model Business Corporation Act spells out a detailed set of principles for identifying the circumstances in which the decision of the directors is entitled to deference. Model Business Corporation Act § 7.44, reprinted in 45 Bus. Law., at 1246-1247. The official commentary acknowledges that these review *105 standards “diffe[r] in certain . . . respects from the law as it has developed in Delaware and been followed in a number of other states.” § 7.44, Official Comment, reprinted in 45 Bus. Law., at 1250.
Indeed, because “[i]n most instances, the shareholder need not specify his legal theory” in his demand,
Allison
v.
General Motors Corp.,
KFS maintains that we should nonetheless affirm the dismissal of petitioner’s cause of action because petitioner did not plead the grounds excusing demand with sufficient particularity for purposes of Federal Rule of Civil Procedure 23.1. Because the Court of Appeals applied a universal-demand rule, it never addressed the sufficiency of petitioner’s complaint with reference to the futility exception as defined by the law of Maryland, the State in which the Fund is incorporated. Rather than take the issue up for the first time ourselves, we leave for the Court of Appeals on remand the question whether petitioner adequately pleaded excuse of demand for purposes of Rule 23.1.
