Appeal from the United States District Court

for the Southern District of Texas

Before HIGGINBOTHAM, SMITH, and GRAVES, Circuit Judges.

PATRICK E. HIGGINBOTHAM, Circuit Judge:

This is another appeal arising out of the collapse of Enron. Plaintiffs are 

individual retail-brokerage customers of Paine-Webber who purchased Enron 

securities and Enron employees who acquired employee stock options. 

Plaintiffs brought this action against subsidiaries of UBS, alleging violations 

of the securities laws for their role as a broker of Enron’s employee stock option 

plan and for failure to disclose material information about Enron’s financial 

manipulations to its retail investors. The case was initially consolidated into

the Enron MDL until the plaintiffs elected to proceed on their own complaint. 

After a lengthy stay and multiple amendments to their original pleading, the 

district court dismissed the complaint for failure to state a claim. We affirm. 

I.

Plaintiffs-Appellants bring this putative class action alleging violations 

of the securities laws against Defendants-Appellees UBS Financial Services, 

Inc. (formerly UBS PaineWebber (“PaineWebber”)) and UBS Securities LLC 

(formerly UBS Warburg LLC (“Warburg”)). During the relevant time period, 

PaineWebber and Warburg were separate legal entities and subsidiaries of 

UBS AG. 

Plaintiffs fall into two groups: (1) individual retail-brokerage customers 

of PaineWebber who purchased Enron securities in a PaineWebber brokerage 

account between November 5, 2000 and December 2, 2001 and (2) Enron 

employees who acquired Enron stock option securities through their 

employment between October 19, 1998 and November 19, 2001, which they 

allege that PaineWebber underwrote (§ 11 claims) and sold (§ 12 claims). 

PaineWebber provided retail brokerage services to individuals and was 

acquired by UBS in July 2000. Warburg provided investment-banking services 

to institutional clients.

Until its collapse in late 2001, Enron was the seventh largest corporation 

in the world. Enron began as a traditional energy production and transmission 

company, concentrating in natural gas pipelines, but quickly grew into an 

“industry leader in the purchase, transportation, marketing, and sale of 

natural gas and electricity” and related financial instruments. Enron’s rapid 

expansion made it a large consumer of cash and the company considered its 

credit ratings critical to its success. According to the complaint, Enron began 

to “seriously manipulate [its] financials” to conceal the negative effects of its

accounting practices on public financial statements. After a series of financial

disclosures and restatements events spiraled: the company’s CFO, Andrew 

Fastow, was placed on a leave of absence, the Board of Directors formed a 

special committee to investigate the financial disclosures, and eventually, 

Enron filed for bankruptcy.

Plaintiffs allege that UBS1 and Enron maintained a “mutually selfserving relationship that took precedence over and conflicted with the interests 

of UBS’s retail customers.” They claim that PaineWebber provided millions of 

retail investors to whom Enron securities could be funneled, transferring 

Enron’s risk into the marketplace and, in return, Enron chose PaineWebber as 

the administrator of its Enron Employee Stock Option Plans, giving UBS the 

“first bite at capturing Enron employee wealth to generate retail fees and 

income.” Enron granted stock option plans to its employees in 1991, 1994, and 

1999.2 Under the terms of the plans, an Enron board committee3 had the sole 

authority to designate participants in the stock plan and determine the types 

of awards to be granted to a participant, which were granted “for no cash 

consideration or for such minimal cash consideration as may be required by 

law.” PaineWebber contracted to provide brokerage services for those plans, 

 

1 Throughout the complaint, plaintiffs refer generally to “UBS.” Plaintiffs state at the 

outset that “P[aine]W[ebber], Warburg, and UBS AG may be collectively referred to herein 

as ‘UBS.’” When describing allegations in the complaint, we use the language of the complaint 

with respect to which defendant was responsible for each alleged action. Defendants reject 

the notion that they can be viewed as a “joint venture” for purposes of assessing liability 

under the securities laws, and that argument is discussed infra, Section III.

2 Defendants attached copies of the 1999 Enron Stock Plan, and the “letter agreement” 

through which PaineWebber agreed to provide broker financing to Enron for the execution of 

employee stock options, to its motion to dismiss before the district court. Those documents 

are properly considered here. Causey v. Sewell Cadillac-Chevrolet, Inc., 394 F.3d 285, 288 

(5th Cir. 2004) (“Documents that a defendant attaches to a motion to dismiss are considered 

part of the pleadings if they are referred to in the plaintiff’s complaint and are central to her 

claim.”).

3 “Committee” is defined as “a committee of the Board of Directors of the Company 

designated by such Board to administer the Plan and composed of not less than two outside 

directors.”

agreeing to serve as the “exclusive broker for stock option exercises of all 

[Enron’s] publicly traded securities.” While Enron granted the options, 

PaineWebber was tasked with facilitating the option exercises and providing

record-keeping services related to the exercise of options. On the basis of those 

allegations, plaintiffs claim violations under Sections 11 and 12 of the 

Securities Act of 1933 (the “Securities Act”).4 Plaintiffs claim that 

PaineWebber violated the Securities Act by acting as a “seller” and 

“underwriter” of Enron securities within the meaning of that statute, making 

PaineWebber liable for “materially false statements contained in the Enron 

prospectuses and registration statements” for Enron stock.

Plaintiffs also allege that UBS had knowledge of Enron’s “financial

chicanery” because of its “long standing banking history with Enron.” 

Emphasizing that UBS is a single, integrated business venture, plaintiffs 

allege that UBS positioned itself between its retail brokerage clients and 

Enron, its corporate client, making it impossible for UBS to fulfill its legal 

obligations to both groups. They claim UBS had material nonpublic 

information about Enron’s financial manipulations and a duty to disclose that 

information to its retail-brokerage customers. Plaintiffs highlight several 

transactions UBS participated in that they allege evidence UBS’s knowledge 

of material information: (1) 1999 and 2000 amendments of equity-forward 

contracts, (2) participation in Osprey and Yosemite IV financial structures, and 

(3) participation in the Enron E-Next Generation Loan. According to plaintiffs, 

those transactions were devices and schemes designed to inflate the 

appearance of Enron’s financial status.

Equity-forward contracts were financial instruments through which 

Enron was contractually obligated to purchase a specific number of Enron 

 

4 15 U.S.C. §§ 77k, 77l.

shares at a specific price from UBS and UBS had to deliver to Enron a specific 

number of shares at a specific price. The complaint alleges that those 

instruments were, in substance, undocumented and undisclosed loans to 

Enron to support Enron’s hedge transactions used to manage its income. It 

documents two restructurings in 1999 and 2000 through which UBS increased 

the forward contract price, allowing Enron to extract the value from the shares 

in the amount of the difference between the initial forward contract price and 

the increased market value of the shares. Plaintiffs allege that these 

restructurings provided Enron hedges for assets that could not be hedged as 

well as seed money for elicit accounting and that UBS had “institutional 

knowledge of their fraudulent nature.”

With respect to its participation in the Osprey and Yosemite IV 

transactions, plaintiffs allege that UBS participated in a follow-on offering of 

notes issued in connection with Enron’s Osprey structure and purchased Enron 

credit-linked notes offered as part of Enron’s Yosemite IV structure. Plaintiffs 

claim that UBS relied on other firms’ diligence and failed to undertake its own 

due diligence in contravention of “relevant industry standards and UBS’s own 

internal policies.” By failing to conduct its own due diligence, plaintiffs claim 

UBS acted recklessly in failing to learn that “Enron used the Osprey structure 

to generate income by parking overvalued, non-performing assets in the 

structure.” Similarly, plaintiffs allege UBS either knew, or was reckless in not 

knowing, that Enron used the Yosemite IV transactions to obtain disguised 

loans.

Finally, plaintiffs allege that E-Next Generation is “the best documented 

example of UBS participating in a materially false public presentation of 

Enron’s financial appearance.” They claim that UBS created an off-balance 

sheet loan to allow Enron to finance “the construction of its US electric 

generating build out and then, once the construction was complete, bring the

project onto Enron’s balance sheet” after it started generating revenues. 

Plaintiffs allege that the existence of the loan and its structure to avoid public 

disclosure were material facts to investors.

On the basis of those allegations, plaintiffs claim violations of Section 

10(b) of the Securities Exchange Act of 1934 (the “Exchange Act”)5 and Rule 

10b-5 thereunder.6 They claim UBS violated Section 10(b) of the Exchange Act 

and Rule 10b-5 thereunder by failing to disclose the conflicts under which it 

operated its brokerage business and the information and knowledge it 

possessed during the class period concerning the manipulation of Enron’s 

public financial appearance. Plaintiffs contend that defendants’ acts, practices, 

and course of business combined to operate a fraud upon the plaintiffs, 

deceiving them “into believing the price at which they purchased or held their 

Enron securities was determined by the natural interplay of supply and 

demand.”

This case was initially filed in March 2002 and has a long procedural 

history. Plaintiffs filed a second amended complaint in June 2002 and, in 

November of that year, this case was coordinated with a multi-district 

litigation under the lead case Newby v. Enron Corp. In November 2003, the 

district court denied defendants’ motion to dismiss the second amended 

complaint and the case proceeded to discovery. In July 2006, the district court 

ordered all MDL plaintiffs who wanted to proceed under their own complaints 

to give notice of that intent, which plaintiffs did, opting to “proceed under their 

own independent complaint, as finally amended.” The operative third amended 

complaint was filed the next month and defendants filed a timely motion to 

dismiss. Shortly thereafter, this court decertified the Newby class7 and the

Supreme Court granted certiorari on a case concerning the scope of liability 

under Section 10(b) of the Exchange Act.8 The district court stayed this case 

pending resolution of Stoneridge by the Supreme Court. Two years after the 

Supreme Court’s decision came down, plaintiffs moved to lift the stay and, a 

year later, the district court lifted that stay. Plaintiffs moved to amend their 

complaint a fourth time and the district court denied plaintiffs’ motion as 

untimely. In February 2017, five and a half years after the stay was lifted, the 

district court granted defendants’ motion to dismiss and denied plaintiffs’ 

subsequent motion for reconsideration. This appeal followed.

“This court reviews de novo a district court’s grant or denial of a Rule 

12(b)(6) motion to dismiss, ‘accepting all well-pleaded facts as true and viewing 

those facts in the light most favorable to the plaintiff[.]’”9 “To survive a motion 

to dismiss, a complaint must contain sufficient factual matter, accepted as 

true, to ‘state a claim to relief that is plausible on its face.’”10 “A claim has facial 

plausibility when the plaintiff pleads factual content that allows the court to 

draw the reasonable inference that the defendant is liable for the misconduct 

alleged.”11 However, “the tenet that a court must accept as true all of the 

allegations contained in a complaint is inapplicable to legal conclusions” or 

“[t]hreadbare recitals of the elements of a cause of action, supported by mere 

conclusory statements.”12 Where a plaintiff alleges fraud, Fed. R. Civ. P. 9(b)

that heightened pleading standard, “the who, what, when, and where must be 

laid out before access to the discovery process is granted.”14 Securities fraud

claims under Section 10(b) are subject to Rule 9(b)’s heightened pleading 

standards.15

This court reviews a district court’s decision denying a motion for leave 

to amend for abuse of discretion.16 Fed. R. Civ. P. 16(b) governs amendments

and provides that a scheduling order “may be modified only for good cause and 

with the judge’s consent.”18 

III.

Plaintiffs bring claims against PaineWebber in its capacity as “the 

exclusive broker and stock option plan administrator for Enron,” contending 

that PaineWebber is liable for false statements in Enron’s prospectuses and 

registration statements. Under Section 11, an underwriter can be liable to a 

person who acquires a security where the registration statement “contained an 

untrue statement of a material fact or omitted to state a material fact required 

to be stated therein.”19 Under Section 12, any person who “offers or sells a 

security,” with a prospectus or oral communication “which includes an untrue 

statement of a material fact or omits to state a material fact necessary in order

to make such statements, in the light of the circumstances under which they 

were made, not misleading,” is liable to the person “purchasing such security 

from him.”20

The parties dispute whether the Enron employee stock option plans 

amounted to a sale of securities within the meaning of the statute. The district 

court held that the stock option plans did not constitute a sale as a matter of 

law because “there is no investment of money in a common enterprise with 

profits to come solely from the efforts of others, for which the plan participants 

expect a profit and . . . because Enron’s stock option plans are noncontributory 

and compulsory for its employees.” Plaintiffs contend that the district court 

erred by conflating employee stock ownership plans and employee stock option

plans. While an employee benefit plan requires a court to determine whether 

the beneficiary interest is a security, plaintiffs assert that the stock options 

here are securities under the statutory definition, meaning the Daniel test to 

determine whether the interest is a security is inapplicable. Relying on the 

same distinction, plaintiffs maintain that the SEC’s “no-sale doctrine” for 

employee benefit plans does not apply to employee stock option plans. 

Plaintiffs contend that there was a “sale” here because the grant of the Enron 

options was “for value”—the provision of services through employment. 

Sections 11 and 12 expressly limit liability to “purchasers or sellers of 

securities.”21 The Securities Act defines a sale as “every contract of sale or 

disposition of a security or interest in a security, for value.”22 In Daniel, the 

Supreme Court determined that an employee’s “participation in a 

noncontributory, compulsory pension plan” is not the equivalent of purchasing

1933 Act confines the cause of action it grants to ‘any person acquiring such security’ while 

the remedy granted by § 12 of that Act is limited to the ‘person purchasing such security.’”).

22 15 U.S.C. § 77b(a)(3).

a security.23 To determine whether a transaction “constitutes an investment 

contract, ‘[t]he test is whether the scheme involves an investment of money in 

a common enterprise with profits to come solely from the efforts of others.’”24

The Court noted that for the employees participating in the pension plan, the 

“purported investment is a relatively insignificant part” of the employee’s total 

compensation, and the decision to accept and retain employment likely had 

only an attenuated relationship to the investment.25 For that reason, 

participation in the noncontributory, compulsory pension plan was unlike 

other cases where the Court recognized “the presence of a ‘security’ under the 

Securities Acts”—in those cases the investor gave up a specific consideration 

in return for a “separable financial interest with the characteristics of a 

security.”26

Shortly after Daniel, the SEC issued a release to “resolve the 

uncertainty” surrounding Daniel’s application to “many types of employee 

benefit plans not covered by the decision.”27 In that release, the SEC clarified 

that “for the registration and antifraud provisions of the 1933 Act to be 

applicable, there must be an offer or sale of a security.”28 The SEC went on to 

explain that although “plans under which an employer awards shares of its 

stock to covered employees at no direct cost to the employees” do award 

securities, “there is no ‘sale’ in the 1933 Act sense to employees, since such 

persons do not individually bargain to contribute cash or other tangible or 

definable consideration to such plans.”29 The following year, the SEC released

a second interpretive release to supplement the 1980 release and “provide 

further guidance and assistance to employers and plan participants in 

complying with the Act.”30 The SEC clarified the definition of voluntary and 

contributory plans, noting “it is the staff’s view that the determination of 

whether a plan is a voluntary contributory one rests solely on whether the 

participating employees can decide at some point whether or not to contribute 

their own funds to the plan.”31 In an interpretive release on Regulation D 

exemptions, the SEC noted “[i]n a typical plan, the grant of the options will not 

be deemed a sale of a security for purposes of the Securities Act.”32

PaineWebber also points to a number of “No Action Letters” sent by the SEC 

that support the conclusion that the SEC does not consider a compulsory option 

grant a “sale” under the Securities Act.33

Consistent with the interpretations of the SEC, courts have extended 

Daniel to compulsory and involuntary employee stock option plans.34 “A

32 SEC Release No. 33-6455, 48 F.R. 10045, 10054 (March 10, 1983). Plaintiffs take 

pains to minimize this statement, correctly noting that it was made in the context of defining 

the scope of Regulation D exemptions for an employee stock option plan for key employees. 

Id. While they are correct about the context, the statement did not explicitly limit its no-sale 

determination to that narrower context. While not determinative on its own, the statement 

further supports PaineWebber’s position that the compulsory option grants were not a sale 

under the meaning of the Securities Act.

33 See e.g., Sarnoff Corp., SEC No-Action Letter, 2001 WL 811033, at *10 (July 16, 

2001) (“As discussed earlier, Sarnoff would give employees Interests or options to acquire 

Interests at no cost, and would receive no cash, property, services, or surrender of a legal 

right in exchange for the Interests or options (including upon exercise of the options). Rather, 

Sarnoff employees would be fully, fairly, and completely compensated for their employment 

activities on behalf of Sarnoff through Sarnoff's standard salary, bonuses, and similar 

compensation. Hence, the Program would not involve the ‘sale,’ ‘offer for sale,’ or ‘solicitation 

of an offer to buy’ securities and no registration therefore should be required under the 

Securities Act.”).

34 See e.g., In re Cendant Corp. Sec. Litig., 76 F. Supp. 2d 539, 544–45 (D.N.J. 1999) 

(“[C]ourts apply the SEC’s ‘no sale’ doctrine when an employee’s plan is found to be 

compulsory and noncontributory. This reasoning has been extended to employee stock option 

plans.”) (internal citation omitted).

hallmark of a ‘voluntary’ plan is the ability of the employee to make an 

‘investment decision’ to acquire the stock options.”35 The central question of 

Daniel is “whether employees made an investment decision that could be 

influenced by fraud or manipulation.”36 Where employees’ participation is an 

“incident of employment,” there is no bargained-for exchange that requires an 

affirmative investment decision37—under Daniel, the “exchange of labor” is 

insufficient.38

Plaintiffs assert that the cases extending the no-sale doctrine to 

employee stock option plans are a pernicious “disease” infecting the federal 

jurisprudence—they maintain that the doctrine is limited to ERISA employee 

benefit plans like the employee pension plan at issue in Daniel and certain 

employee stock ownership plans. But as the district court correctly recognized, 

the grant of options to employees here was not a sale. The employees did not 

bargain for the options and they were granted for no cash consideration. 

Plaintiffs attempt to distinguish option grants by pointing out that the 

employees would be forced to make an affirmative investment decision after 

the grants were made—at that point, employees would decide whether to 

exercise the option or allow it to expire unexercised. However, plaintiffs 

expressly disclaim reliance on the exercise of the options. Indeed they 

repeatedly emphasize that “[t]he Options Plaintiffs’ claims in no way depend 

upon the exercise of a stock option to purchase the underlying stock.” Their 

claim is based entirely on the grant of the options—an action which required 

no affirmative investment decision by the plaintiffs. Their theory that option

grants fall outside the purview of the no-sale doctrine is contradictory: the 

affirmative investment decision is made when the employees decide whether 

to exercise their options, but their claims are explicitly based only on the grant 

of the options.

Finding no caselaw to support their position, plaintiffs rely heavily on an 

SEC proceeding against Google, Inc. and David Drummond, Google’s general 

counsel.39 The SEC instituted cease-and-desist proceedings against Google and 

Drummond for failing to comply with Rule 701, which provides certain 

Securities Act exemptions to securities issuers who are not subject to the 

Exchange Act’s reporting requirements.40 Rule 701 is designed to “allow[]

privately-held companies to compensate their employees with securities 

without incurring the obligations of public registration and reporting.”41 The 

SEC determined that Google—a privately-held company to whom Rule 701 

applied—and Drummond violated or caused the company to violate its 

reporting requirements by exceeding the $5 million threshold set out by Rule 

701.42 Plaintiffs contend that the proceedings “confirm” that granting stock 

options involves a sale within the meaning of the Securities Act. Plaintiffs 

overread those proceedings. While their interpretation is a plausible extension 

of the Google decision, the SEC did not address the no-sale doctrine and made 

its decision in the context of concluding which exemptions a private company 

could take advantage of.43 We are not persuaded that the SEC’s decision in 

Google indicates a wholesale rejection of the no-sale doctrine in the context of

employee option grants. Finally, even if the Google decision did represent a 

change in the SEC’s stance—and we conclude it does not—plaintiffs fail to 

show how that 2005 decision could be applied retroactively to PaineWebber’s 

actions between 1998 and 2001.44

At base, plaintiffs Securities Act claims fail because their participation 

in the Employee Stock Option Plan was compulsory and employees furnished 

no value, or tangible and definable consideration in exchange for the option 

grants. The Court in Daniel rejected the idea that the exchange of labor was 

sufficient consideration in the context of a compulsory, non-contributory 

pension plan—the same logic applies to the option plan at issue here.45

Plaintiffs made no investment decision in the grant of the options, the Enron 

plans were compulsory and non-contributory. The fact that plaintiffs would 

eventually make an affirmative investment decision—whether to exercise the 

option or let it expire—at some point in the future is of no consequence. 

Plaintiffs’ claims are based explicitly on the grant of the option, not the exercise 

of that option. Because plaintiffs have not overcome the most fundamental 

hurdle to their Securities Act claims, we need not consider UBS’s alternative 

arguments that (1) PaineWebber was not an underwriter or seller; (2) plaintiffs 

failed to allege that any false prospectus or registration statement covered the 

Enron options; and (3) that plaintiffs failed to plead damages. Plaintiffs’

Securities Act claims require a sale—plaintiffs have failed to demonstrate that 

the grant of Enron options amounted to the sale of a security. For those 

reasons, the district court correctly dismissed plaintiffs’ Section 11 and Section 

12 claims.

IV.

In their second set of claims, the retail-brokerage customer plaintiffs 

contend that UBS violated Section 10(b) of the Exchange Act and Rule 10b-5 

thereunder by failing to disclose information and knowledge regarding “the 

manipulation of Enron’s public financial appearance” in the face of a duty to 

do so. To state a claim for securities fraud under Section 10(b) of the Exchange 

Act, a plaintiff must adequately allege “(1) a material misrepresentation (or 

omission); (2) scienter, i.e., a wrongful state of mind; (3) a connection with the 

purchase or sale of a security; (4) reliance . . .; (5) economic loss; and (6) loss 

causation, i.e., a causal connection between the material misrepresentation 

and the loss.”46 Plaintiffs’ claims are based on UBS’s alleged silence in violation 

of a duty to disclose. The crux of plaintiffs’ claim is that PaineWebber and 

Warburg united in a joint venture named UBS, that that joint venture owed a 

duty to its retail brokerage clients stemming from the security industry’s selfregulatory organization rules and UBS’s “special relationship” with plaintiffs, 

and that UBS failed to disclose information that “Enron manipulated and 

materially misstated its financial results to the public.”

The district court concluded that plaintiffs failed to plead sufficient facts 

to support a plausible claim that Warburg and PaineWebber functioned as a 

single entity, did not establish that defendants acted with scienter, and did not 

establish that Warburg or UBS AG, which were not parties to the contract 

between Enron and PaineWebber, owed a duty to plaintiffs. Essentially, the 

district court determined that plaintiffs had not shown that Warburg owed a 

duty to disclose information it possessed to clients of PaineWebber by virtue of 

any “joint venture” between Warburg and PaineWebber and, in fact, that

Warburg could not share information with PaineWebber because of “federally 

required Chinese Walls” between PaineWebber and Warburg, in its capacity 

as an investment bank.

After the parties submitted their briefing in this case, another panel of 

this court issued an unpublished decision in a related case, affirming the same 

district court’s dismissal of similar Exchange Act claims brought by 

PaineWebber customers who had bought Enron bonds or other debt 

instruments.47 In their response to defendants’ 28(j) letter, plaintiffs attempt 

to distinguish Giancarlo by stating that the panel “simply found the [appellate] 

briefing submitted by the Giancarlo plaintiffs’ insufficient to demonstrate a § 

10(b) claim” and based its decision on those deficiencies rather than “perceived 

deficiencies in their pleading in the trial court.”48 Plaintiffs assert that the 

panel’s decision “is not a decision on the merits of the § 10(b) claim asserted by 

the Plaintiffs in the Lampkin case.”49 That characterization is inconsistent 

with the panel opinion, which held that plaintiffs had not adequately 

established the existence of a joint venture, nor put forth any other theory that 

permitted aggregation of the actions and knowledge of the defendant entities,50

and had failed to establish that any one defendant had material non-public 

knowledge and a duty to disclose that knowledge to the plaintiffs.51 The panel 

concluded, therefore, that “the district court properly dismissed Plaintiffs’

cert denied, 139 S. Ct. 199 (2018). As defendants note in their 28(j) letter to this court, 

Giancarlo was litigated in parallel with the instant action by the same counsel before the 

same district court. See Feb. 28, 2018 28(j) Letter.

amended complaint.”52 Although we are not bound by an unpublished decision, 

we find the reasoning in Giancarlo persuasive and adopt it here.

First, plaintiffs contend that they adequately alleged that PaineWebber

and Warburg united to form a joint venture named UBS. Plaintiffs urge that 

because PaineWebber and Warburg were incorporated under Delaware law, 

the court looks to the Delaware standard for establishing that a joint venture 

exists: where there is (1) a community of interest in the performance of a 

common purpose, (2) joint control or right of control, (3) a joint proprietary 

interest in the subject matter, (4) a right to share in the profits, (5) a duty to 

share in the losses which must be sustained.53 Plaintiffs point to allegations 

that UBS made public admissions in media releases describing itself as an 

“integrated” bank and predicted in a press release after PaineWebber’s 

acquisition that PaineWebber would become “an integral part of UBS 

Warburg.” However, like the plaintiffs in Giancarlo, plaintiffs here do not 

explain how the allegations they point to support a finding that defendants 

shared profits or losses or establish that defendants had joint control or right 

of control over the joint venture.54 The press releases described by plaintiffs 

support a shared interest but are insufficient to support joint venture liability 

under Delaware law—as this court in Giancarlo emphasized, “vague corporate 

platitudes about integration as a firm” are insufficient to support a finding of 

joint venture liability.55 Beyond plaintiffs’ conclusory statements that UBS

was a single, integrated entity, plaintiffs have not established the existence of 

a joint venture and, as in Giancarlo, “have not put forth any other theory that 

permits us to aggregate the actions and knowledge of the defendant entities 

for purposes of assessing liability.”56

With respect to duty, plaintiffs contend that defendants had knowledge 

of material nonpublic information concerning Enron and that they owed a duty 

to disclose that information. Plaintiffs assert that a duty to disclose arose 

through UBS’s retail brokerage relationship with plaintiffs and through UBS’s 

“special relationship” as a entity between its retail client and its issuer client. 

Because, as we discussed, plaintiffs have not adequately pled that Warburg 

and PaineWebber formed a joint venture, they must demonstrate that the 

entity that possessed the material, nonpublic information—according to 

plaintiffs allegations, Warburg or UBS AG—had the duty to disclose that 

information.57

Plaintiffs emphasize that a duty to disclose can arise without the 

existence of a fiduciary duty, and point to two sources of the alleged duty here.

First, they contend that the security industry’s self-regulation rules give rise 

to actionable duties under the Exchange Act. According to plaintiffs, the

integration of a retail brokerage business (PaineWebber) into the joint venture 

brought with it duties placed on broker-dealers by the rules of two selfregulatory organizations (“SROs”), the NASD and NYSE. Plaintiffs claim that 

the NASD and NYSE “establish obligatory standards” and “obligated UBS to 

 

form” where it was “undisputed that the corporate formalities were observed” and entities 

remained legally separate).

57 Giancarlo, 725 F. App’x at 284 (“Moreover, even a searching review of the relevant 

documents supports, at most, that Warburg and UBS AG had some insider knowledge of 

Enron’s financial situation, as those are the defendants that participated in the transactions 

identified by Plaintiffs. Thus, Plaintiffs must show that Warburg or UBS AG owed them a 

duty of disclosure.”).

speak.” Plaintiffs’ complaint cites to NASD Rule 2210(d) which governs “[a]ll 

member communications with the public” and mandates that “[n]o material 

fact or qualification may be omitted if the omission . . . would cause the 

communications to be misleading.” This theory of duty falls with plaintiffs’ 

theory of joint venture liability. The SRO rules depend on a communication—

but as in Giancarlo, PaineWebber was the entity that communicated with the 

retail brokerage customer plaintiffs but plaintiffs fail to allege that 

PaineWebber had knowledge of Enron’s financial misrepresentations.58 The 

defendant with the duty was not the defendant with the knowledge. Simply 

labeling the offending entity “UBS” does not rescue plaintiffs from this fatal 

flaw.

Plaintiffs also point to a second source of defendants’ alleged duty, the 

alleged “special relationship” between UBS and plaintiffs. Essentially, 

plaintiffs claim that UBS stood between Enron and its retail brokerage 

customers and that special relationship obligated its disclosure about Enron’s 

financial manipulations. In support of this alleged duty, plaintiffs rely on 

Affiliated Ute Citizens of Utah v. United States.59 In Affiliated Ute, a bank that 

was acting as a transfer agent for Ute tribe members bought the plaintiffs’ 

restricted stock without disclosing that they had created a secondary market 

for the stock where they could sell it for a profit.60 The Court held that the 

“sellers had the right to know that the defendants were in a position to gain 

financially from their sales and that their shares were selling for a higher price 

 

58 Giancarlo, 725 F. App’x at 285 (“The only defendant alleged to have ‘communicated’

with Plaintiffs is PaineWebber, and Plaintiffs have not sufficiently alleged that any person 

at PaineWebber had knowledge concerning Enron’s financial manipulations. Thus, even if 

we accepted Plaintiffs’ invitation to hold that NASD rules can impose a duty of disclosure for 

purposes of § 10(b) liability, Plaintiffs have not shown that any defendant violated such 

rules.”) (internal citations omitted).

in that market.”61 Plaintiffs have not alleged an analogous relationship 

between themselves and the entity that sold them securities, PaineWebber. 

Furthermore, plaintiffs do not suggest that PaineWebber was the entity that 

had knowledge of the Enron securities market.62 PaineWebber was the broker 

for the retail-brokerage customers while UBS AG and Warburg were the 

entities that played a role in the particular transactions identified in the 

complaint purporting to evidence the material knowledge of Enron’s financial 

manipulations—again, plaintiffs’ use of the grouping “UBS” does not cure the 

fact of those entities’ separate legal statuses.

Plaintiffs fundamentally fail to establish that either defendant had 

material, nonpublic knowledge to disclose and a duty to disclose. They attempt 

to circumvent this requirement by arguing that UBS operated as a “single, 

fully integrated entity,” meaning that any material, nonpublic information 

known to UBS AG or Warburg had to be disclosed by PaineWebber. Because 

they have not adequately pled that defendants formed a joint venture, the lack 

of particularized allegations that any defendant entity possessed material 

information about Enron’s finances and a duty of disclosure are fatal to their 

claim.63

62 See e.g., Giancarlo, 725 F. App’x at 286 (“Documents attached to the pleadings 

discuss the role of ‘UBS Warburg AG’ in several transactions and indicate that that ‘UBS 

Warburg’ was the ‘joint lead manager of Credit Linked Notes for Enron.’ Plaintiffs specify 

that their brokers were employees of PaineWebber. Plaintiffs do not argue that PaineWebber 

had any special knowledge of the market for Enron debt securities, and UBS AG’s and 

Warburg’s dealings with Enron cannot support that PaineWebber had a duty of disclosure.”).

V.

Plaintiffs contend that, even if their third amended complaint was 

properly dismissed by the district court, the court abused its discretion in 

denying them the opportunity to file an amended complaint.

While Fed. R. Civ. P. 15(a) provides that leave to amend shall be “freely” 

given,64 where a plaintiff seeks to amend its complaint after a scheduling order 

has been entered, Fed. R. Civ. P. 16(b) governs.65 Under that rule, a scheduling 

order “may be modified only for good cause and with the judge’s consent.”66 

The court must consider four factors in determining whether there was good 

cause for the delay: (1) the explanation for the failure to timely move for leave 

to amend, (2) the importance of the amendment, (3) the potential prejudice the 

other party would suffer if the amendment was allowed, and (4) the availability 

of a continuance to cure that prejudice.67 

Plaintiffs explain their failure to seek timely amendment, pointing to 

depositions of Enron’s former CFO and UBS’s expert, which were taken after 

the amendment deadline, and UBS’s “unforeseeable denial” of facts admitted 

to in its SEC filings. As this court recognized in Giancarlo, which proceeded 

under a similar schedule, Enron’s CFO was deposed eight months before this 

action was stayed, during which time plaintiffs failed to seek to amend their 

complaint.68 Plaintiffs waited a full two years after Stoneridge was decided 

before moving to lift the stay. Plaintiffs’ suggestion that they could not have 

predicted that defendants would argue that Warburg and PaineWebber are 

separate legal entities is implausible given the reference to different entities

in different allegations of the operative complaint. Plaintiffs also submit that 

the proposed amendment was “clearly” important given the dismissal in the 

case. Again, as in Giancarlo, that conclusory statement does not tell this court 

which new allegations would cure the deficiencies highlighted by the district 

court.69 Specifically, plaintiffs have not made clear how their revised 

allegations would support their theory that PaineWebber and Warburg 

participated in a joint venture. Even taking plaintiffs at their word that 

defendants would not have been overly prejudiced by the proposed 

amendment, the first two factors in the analysis are determinative here. The 

district court did not abuse its discretion in refusing to grant leave to amend. 

VI.

Because plaintiffs failed to state a claim under the Securities Act or the 

Exchange Act and the district court did not abuse its discretion in denying 

plaintiffs an additional chance to amend their complaint, we affirm the district 

court’s dismissal.
