I. INTRODUCTION
Plaintiffs in this securities action have moved for certification of a damages class under

18

Federal Rule of Civil Procedure 23(b)(3). Defendants, in opposition, focus largely on the

19

contention that Plaintiffs have not established typicality or predominance because their

20

acquisitions of Bayer American Depositary Receipts do not qualify as domestic transactions under

21

federal securities law. As discussed in greater detail below, this argument is not persuasive, and

22

there are no significant extraterritoriality concerns on the record presented. Defendants’ additional

23

arguments against class certification are similarly unconvincing. Because Plaintiffs have made all

24

the requisite showings under Rule 23, the proposed class will be certified.

25
26

II. BACKGROUND
As discussed previously, e.g., Dkt. 90, this case arises out of averred misrepresentations

27

made by Bayer and its executives in connection with the company’s acquisition of the

28

agrochemical company Monsanto. In the Second Amended Class Action Complaint (“SAC”),

Case 3:20-cv-04737-RS Document 175 Filed 05/19/23 Page 2 of 17

1

Plaintiffs bring claims under sections 10(b) and 20(a) of the Securities Exchange Act of 1934, 15

2

U.S.C. § 78j(b); and Rule 10b-5 promulgated thereunder, 17 C.F.R. § 240.10b-5. These claims are

3

based on two categories of averred misrepresentations, only one of which (Defendants’ alleged

4

statements concerning Bayer’s due diligence efforts surrounding the Monsanto acquisition) was

5

pleaded adequately and remains a viable theory of liability. See Dkt. 122.
Plaintiffs are each pension funds that collectively purchased close to 600,000 Bayer

American Depositary Receipts, or “ADRs.” ADRs are “negotiable certificates issued by a United

8

States depositary institution, typically banks, and they represent a beneficial interest in, but not

9

legal title of, a specified number of shares of a non-United States company.” Stoyas v. Toshiba

10

Corp., 896 F.3d 933, 940 (9th Cir. 2018). Purchasing ADRs “allow[s] American investors to trade

11

equities of a foreign corporation domestically.” Pinker v. Roche Holdings Ltd., 292 F.3d 361, 371

12

(3d Cir. 2002). Bayer ADRs are traded in the over-the-counter (“OTC”) market,1 and each ADR

13

represents an ownership interest “in ordinary shares of Bayer that [have been] held on deposit by

14

The Bank of New York Mellon.” Dkt. 107 (“SAC”) ¶ 38.
After two motions to dismiss were denied, Plaintiffs moved for certification of a damages

15
16

class under Rule 23(b)(3). The proposed class is defined as follows:
[A]ll persons or entities that purchased or otherwise acquired Bayer’s
publicly traded [ADRs] from May 23, 2016 to July 6, 2020, inclusive
(the “Class Period”). Excluded from the Class are (1) Defendants; (2)
members of the immediate family of each of the Individual
Defendants; (3) any subsidiary or affiliate of Bayer, including its
employee retirement and benefit plan(s) and their participants or
beneficiaries, to the extent they made purchases through such plan(s);
(4) the directors and officers of Bayer during the Class Period, as well
as the members of their immediate families; and (5) the legal
representatives, heirs, successors, and assigns of any such excluded
party.

more fragmented ‘market maker’ system.” 1 THOMAS LEE HAZEN, TREATISE ON THE LAW OF

for appointment of Cohen Milstein Sellers & Toll PLLC as Class Counsel.
In support of their motion, Plaintiffs rely on the expert report of Dr. Joshua Mitts, who

3

looks to trading data to determine that irrevocable liability for purchasing Bayer ADRs occurred

4

within the United States. They also refer to the expert report of Chad Coffman, a financial analyst

5

who discusses the efficiency of the Bayer ADR market during the Class Period and describes an

6

“out-of-pocket” model for measuring classwide damages. Defendants, for their part, rely on the

7

expert testimony of Cristian Zarcu. Mr. Zarcu reaches the opposite conclusion as Dr. Mitts,

8

arguing that, based on his examination of the trading data and his experience as a trader, such

9

irrevocable liability occurred outside the United States for many of the ADRs purchased by the

10

putative class members. Defendants also provide expert testimony from Dr. Mark Garmaise,

11

whose report rebuts Mr. Coffman’s findings on market efficiency and critiques his approach to

12

calculating damages. Finally, Plaintiffs offer rebuttal reports from Dr. Mitts and Mr. Coffman.

13

III. LEGAL STANDARD
Class actions are governed by Rule 23 of the Federal Rules of Civil Procedure. To obtain

15

class certification, plaintiffs bear the burden of showing they have met each of the four

16

requirements of Rule 23(a) and at least one subsection of Rule 23(b). Zinser v. Accufix Rsch. Inst.,

17

Inc., 253 F.3d 1180, 1186 (9th Cir.), amended by 273 F.3d 1266 (9th Cir. 2001). Plaintiffs must

18

establish these requirements by a preponderance of the evidence. Olean Wholesale Grocery

19

Cooperative, Inc. v. Bumble Bee Foods LLC, 31 F.4th 651, 665 (9th Cir. 2022) (en banc).

20

Rule 23(a) provides that a court may certify a class only if the following four requirements

21

are met: “(1) the class is so numerous that joinder of all members is impracticable; (2) there are

22

questions of law or fact common to the class; (3) the claims or defenses of the representative

23

parties are typical of the claims or defenses of the class; and (4) the representative parties will

24

fairly and adequately protect the interests of the class.” Fed. R. Civ. P. 23(a). These requirements

25

are commonly referred to as numerosity, commonality, typicality, and adequacy of representation,

26

respectively. Mazza v. Am. Honda Motor Co., Inc., 666 F.3d 581, 588 (9th Cir. 2012).

27

If all four Rule 23(a) prerequisites are satisfied, plaintiffs must also “satisfy through

1

evidentiary proof” at least one of the three subsections of Rule 23(b). Comcast Corp. v. Behrend,

2

569 U.S. 27, 33 (2013). Rule 23(b)(3) requires that “the questions of law or fact common to class

3

members predominate over any questions affecting only individual members, and that a class

4

action is superior to other available methods for fairly and efficiently adjudicating the

5

controversy.” Fed. R. Civ. P. 23(b)(3). Such common questions need only be capable of classwide

6

resolution; plaintiffs are not required to show that “the evidence in fact establishes [they] would

7

win at trial.” Olean, 31 F.4th at 667. If these showings have been made and the class is certified,

8

the court must appoint class counsel. Fed. R. Civ. P. 23(g).

IV. DISCUSSION

United States District Court
Northern District of California

10

Defendants’ main argument is that class certification is inappropriate because many of

11

Plaintiffs’ transactions occurred outside of the United States. On this basis, Defendants contest

12

Plaintiffs’ assertion that they have shown typicality and the predominance of common questions.

13

As this constitutes the primary zone of disagreement between the parties, the first section below

14

provides an overview of the relevant law in this area, followed by a discussion of how Plaintiffs

15

acquired Bayer ADRs. For the reasons laid out at the end of that section, Plaintiffs’ transactions do

16

not raise extraterritoriality concerns. As the following two sections then discuss, Plaintiffs have

17

established each requirement under Rule 23(a) and Rule 23(b)(3).

18

A. The Proposed Class Does Not Present Extraterritoriality Concerns

19

1. “Domestic Transactions” of Securities: Morrison and Toshiba

20

The Exchange Act and Rule 10b-5 both prohibit misleading statements made in connection

21

with the sale of a security in a domestic market. In Morrison v. Nat’l Australia Bank Ltd., 561

22

U.S. 247 (2010), the Supreme Court specifically addressed the territorial scope of the Exchange

23

Act, given significant disparities in how the Circuits had interpreted the Act to that point. Looking

24

to the text, the Court clarified the Act applies only to “transactions in securities listed on domestic

25

exchanges, and domestic transactions in other securities.” Id. at 267. Whether a security falls into

26

the latter category turns exclusively on “whether the purchase or sale is made in the United

27

States,” rather than whether the alleged misleading conduct occurred in the United States. Id. at

Case 3:20-cv-04737-RS Document 175 Filed 05/19/23 Page 5 of 17

1

269–70. Thus, if the transactions occur outside the United States, the Act does not apply. This, the

2

Court reasoned, was clear based on the jurisprudential presumption against extraterritorial

3

application of American law; the problematic “interference with foreign securities regulation that

4

application of § 10(b) abroad would produce”; and the fact that a contrary reading would “make

5

nonsense” of the Act’s text. Id. at 268–69 & n.10.

United States District Court
Northern District of California

6

Although ADRs are not the same as regular shares of a foreign corporation and do not

7

necessarily trade on national exchanges, they are nonetheless “securities” under the Exchange Act.

8

See Toshiba, 896 F.3d at 939–42, 947. Given Morrison’s firm command that a security not listed

9

on a national exchange must be purchased or sold in the United States, the Ninth Circuit in Stoyas

10

v. Toshiba Corp. adopted the “irrevocable liability test” to determine where a transaction occurred

11

for the purposes of the Exchange Act. This test, which comes from the Second Circuit’s decision

12

in Absolute Activist Value Master Fund Ltd. v. Ficeto, 677 F.3d 60 (2d Cir. 2012), holds that a

13

plaintiff must make at least one of three showings to establish a transaction was domestic: (1) “the

14

purchaser incurred irrevocable liability within the United States to take and pay for a security”; (2)

15

“the seller incurred irrevocable liability within the United States to deliver a security”; or (3) title

16

to the securities was transferred within the United States. Toshiba, 896 F.3d at 948 (quoting

17

Absolute Activist, 677 F.3d at 67–68).

18

This formulation of the irrevocable liability test requires clarification, as the Toshiba Court

19

did not clearly delineate these showings as three distinct prongs. In Toshiba, the Court stated that

20

the test was intended to capture “where purchasers incurred the liability to take and pay for

21

securities, and where sellers incurred the liability to deliver securities.” Toshiba, 896 F.3d at 949.

22

It went on to note that passing of title, among other factual allegations, could evidence a domestic

23

transaction. Id. Yet, as Plaintiffs correctly observe, the Ninth Circuit “has yet to rule on whether

24

the passing of title to an ADR is sufficient to establish domesticity, as this argument was not

25

raised in [Toshiba].” Dkt. 163 (“Reply”), at 7 n.4.

26
27

Defendants understand Toshiba to include only the first two prongs listed above as part of
the irrevocable liability test, and they argue transfer of title is a different test altogether. This

Case 3:20-cv-04737-RS Document 175 Filed 05/19/23 Page 6 of 17

1

argument relies almost entirely on the fact that in Toshiba, when the Court discussed Absolute

2

Activist, it noted that “[t]he Second Circuit also found an alternative means of alleging a domestic

3

transaction: alleging that title to the shares was transferred in the U.S.” 896 F.3d at 948 (emphasis

4

added). Based on this verbiage, Defendants argue the Ninth Circuit has not accepted transfer of

5

title as sufficient to show a domestic transaction.

United States District Court
Northern District of California

6

This is a cramped reading of Toshiba and an incorrect view of the irrevocable liability test,

7

for several reasons. First, courts both before and after Toshiba have recognized that the transfer-

8

of-title prong is a part of the irrevocable liability test. See Takiguchi v. MRI Int’l, Inc., 47 F. Supp.

9

3d 1100, 1109 (D. Nev. 2014); In re Tezos Sec. Litig., No. 17-cv-06779-RS, 2018 WL 4293341, at

10

*8 (N.D. Cal. Aug. 7, 2018); In re Volkswagen AG Sec. Litig., No. 122CV00045RDAWEF, 2023

11

WL 2505539, at *11 (E.D. Va. Mar. 14, 2023). This includes several of the Ninth Circuit district

12

court decisions Toshiba cited in support of adopting the Absolute Activist test. See SEC v. Yin Nan

13

Michael Wang, No. LA CV13-07553 JAK (SSx), 2015 WL 12656906, at *10 (C.D. Cal. Aug. 18,

14

2015) (“Thus, the issue presented is where irrevocable liability was incurred or where title to the

15

securities passed.”); In re Volkswagen “Clean Diesel” Mktg., Sales Pracs., & Prod. Liab. Litig.,

16

No. 2672 CRB (JSC), 2017 WL 66281, at *3 (N.D. Cal. Jan. 4, 2017). Commentators have

17

likewise read Toshiba to have adopted all three prongs. 17 J. WILLIAM HICKS, CIVIL LIABILITIES:

18

ENFORCEMENT & LITIGATION UNDER THE 1933 ACT § 4.4, Westlaw (database updated May 2023)

19

(describing Toshiba as having “adopted the ‘irrevocable liability’ test,” which requires showing

20

either “(1) irrevocable liability is incurred in the United States or (2) title passes within the United

21

States”); 1 HAROLD S. BLOOMENTHAL & SAMUEL WOOLF, SECURITIES LAW HANDBOOK § 22:102,

22

Westlaw (database updated June 2022) (same).

23

By the same token, the Toshiba Court never disavowed the transfer-of-title prong. While it

24

is true the Court used the word “alternative” to describe the transfer-of-title prong, it did not

25

describe it as an alternative test. The better reading of this portion of the opinion is to see this as an

26

effort by the Court to differentiate the first two prongs, which both include the words “irrevocable

27

liability,” from the transfer-of-title prong, which does not. The transfer-of-title prong is,

1

furthermore, fully consistent with the concept of irrevocable liability; it thus fits comfortably with

2

the first two prongs under the overarching umbrella of “the irrevocable liability test.” In addition,

3

the Court expressly rejected the “predominantly foreign” test for domesticity, which it found

4

unpersuasive. See 896 F.3d at 950 (distinguishing Parkcentral Global Hub v. Porsche Automobile

5

Holdings, 763 F.3d 198 (2d Cir. 2014)). One would expect the Ninth Circuit to have offered

6

similar reasoning (or any reasoning) if its intent was to reject transfer-of-title prong.
Thus, under Toshiba, a plaintiff can establish domesticity by showing that the buyer or

United States District Court
Northern District of California

7
8

seller incurred irrevocable liability within the United States, or by showing that title to a security

9

passed within the United States. Only one of these prongs needs to be established to allay

10

extraterritoriality concerns. This understanding is consistent with Toshiba, Absolute Activist, and

11

Morrison and the reasoning underpinning these decisions, and it is in line with the numerous other

12

district court decisions that have adopted this construction.

13

2. How Bayer ADRs Were Acquired

14

Buying securities is more complex than buying groceries. This is especially true where a

15

security, like an ADR, itself relies on a foreign security. Both parties’ experts generally agree as to

16

the process for how Plaintiffs acquired Bayer ADRs (though they reach different conclusions

17

about whether these transactions were domestic under Morrison). As the details of this process are

18

relevant to the domesticity determination of the trades, it must be examined.

19

As noted above, Plaintiffs each worked with an outside investment manager at all relevant

20

times.2 The investment managers, in turn, worked with at least one broker-dealer to acquire Bayer

21

ADRs.3 When deciding to invest in ADRs, the investment managers could choose between (1)

22

purchasing existing ADRs available on the OTC market, or (2) “purchas[ing] shares on the foreign

exchange and arrang[ing] for the issuance of new ADRs by depositing the foreign-bought shares

2

with a depositary bank.” Dkt. 151-29 (“Zarcu Rpt.”) ¶ 20. As Mr. Zarcu explains, the cost of trade

3

execution is the primary factor influencing this decision; sometimes, though, an investor may want

4

to buy more ADRs than the market of existing ADRs has to offer, so the only option would be to

5

seek issuance of new ADRs. Id.
Trades of existing ADRs made up over 80% of the ADR transactions involved in this case,

United States District Court
Northern District of California

6
7

and they were executed “[l]ike transactions in any other domestic security.” Dkt. 141-2 (“Mitts

8

Rpt.”) ¶ 28; see Zarcu Rpt. ¶ 125. The remainder involved issuances of new ADRs, which

9

included a few more steps. In these instances, a broker-dealer acquired Bayer shares from the

10

Frankfurt Stock Exchange in Germany. The broker-dealer then placed ADR orders with Bank of

11

New York Mellon (“BONY”), which is the exclusive depositary institution for Bayer shares.4

12

Once the shares were deposited with BONY, the Bank then issued ADRs back to the broker-dealer

13

(sometimes by way of another intermediary, like Citibank), who then transferred the ADRs into

14

the Plaintiffs’ custody. Mitts Rpt. ¶¶ 39, 45–49.

15

3. Analysis

16

Though the parties largely agree on how the trades were executed here, they disagree as to

17

where in the transaction process irrevocable liability was incurred. Defendants do not challenge

18

the transactions involving existing ADRs, but they argue that, for the roughly 20% of trades

19

involving new ADRs, Plaintiffs incurred irrevocable liability for the purchases “at the moment

20
21
22
23
24
25
26
27

Bayer ADRs are “sponsored” ADRs, as further evidenced by both Bayer’s and BONY’s public
representations. Mitts Rpt. ¶ 27. This is in contrast to “unsponsored” ADRs. The Third Circuit has
described the general differences between the two:
4

An unsponsored ADR is established with little or no involvement of
the issuer of the underlying security. A sponsored ADR, in contrast,
is established with the active participation of the issuer of the
underlying security. An issuer who sponsors an ADR enters into an
agreement with the depositary bank and the ADR owners. The
agreement establishes the terms of the ADRs and the rights and
obligations of the parties, such as the ADR holders’ voting rights.

their brokers executed the purchase of Bayer ordinary shares in Europe.” Dkt. 150 (“Opp.”), at 9;

2

see Zarcu Rpt. ¶ 32 (noting that securities clients are never “permitted to revoke an order after the

3

initial overseas purchase”). Irrevocable liability thus occurred outside the United States. Dr. Mitts,

4

on the other hand, suggests this view is misplaced: irrevocable liability was incurred when BONY

5

issued the ADRs to the broker-dealers, which occurred in the United States. See Mitts Rpt. ¶ 39. In

6

other words, for Defendants, the salient act is the purchase of Bayer shares in Germany that led to

7

the creation of the ADRs; for Plaintiffs, the salient act is the issuance of the ADRs themselves.
Defendants rely heavily on Stoyas v. Toshiba Corp. (“Toshiba II”), No. 15-cv-04194 DDP-

United States District Court
Northern District of California

8
9

JC, 2022 WL 220920 (C.D. Cal. Jan. 25, 2022), the district court order that followed the Ninth

10

Circuit’s remand in Toshiba. There, reviewing a very similar set of facts, the court denied class

11

certification on extraterritoriality grounds.5 It concluded the plaintiffs’ acquisition of newly issued

12

ADRs began “with the trade of underlying Toshiba common stock.” Id. at *5. Once this occurred,

13

the plaintiffs were “logically and legally bound to perform [their] contractual obligations.” Id. at

14

*4. “Thus, the triggering event that caused ClearBridge [the investment manager] (and by

15

extension, [plaintiffs]) to incur irrevocable liability occurred in Japan when Barclays [the broker-

16

dealer] acquired the shares of Toshiba common stock on the Tokyo Stock Exchange.” Id.
While Toshiba II’s logic is initially appealing, especially considering the underlying

17
18

factual similarities with the present case, its analysis is incomplete. The court focused exclusively

19

on the first prong of the irrevocable liability test without analyzing the second or third: where the

20

seller incurred irrevocable liability, and where title to the ADRs was transferred. Here, neither

21

Defendants nor Mr. Zarcu meaningfully address these two prongs, yet either can serve as a basis

22

for concluding the transactions at issue do not raise extraterritoriality concerns. First, Plaintiffs

23

have shown that the seller of the ADRs (i.e., BONY) incurred irrevocable liability to deliver the

24

securities once the broker-dealers deposited the Bayer shares they had acquired in Germany. Mitts

25
26

5

Toshiba II appears to be the only district court decision in the Ninth Circuit thus far that has
applied Toshiba’s irrevocable liability test in the context of a motion for class certification.

Rpt. ¶ 38 & n.44. Relatedly, Plaintiffs have shown that title to the ADRs was transferred between

2

BONY and one of the relevant broker-dealers, and, subsequently, from the broker-dealers to

3

Plaintiffs (via the investment managers). Dkt. 164-1 (“Mitts Reply Rpt.”) ¶¶ 14–17 & n.23.6 All of

4

these acts occurred in the United States.

5

Defendants contend, in effect, that Plaintiffs cannot satisfy the test because they incurred

6

irrevocable liability when their brokers purchased Bayer shares in Frankfurt. Even accepting this

7

as true, it does not negate or somehow outweigh the fact that Plaintiffs have satisfied the other two

8

prongs of the irrevocable liability test. Morrison’s singular focus on domestic transactions

9

stemmed from an aversion to multifactor tests with “unpredictable and inconsistent

10

application[s],” 561 U.S. at 260, instead favoring a bright-line rule, id. at 285 (Stevens, J.,

11

concurring). Morrison thus supports the conclusion that all three Toshiba prongs are equally valid

12

in determining whether a transaction is domestic and need not (indeed, should not) be weighed

13

against each other. As long as one is shown, a domestic transaction has occurred. The test should

14

thus be understood as a rule of inclusion: together, all three prongs help actualize Morrison’s

15

intent to ensure Exchange Act and Rule 10b-5 claims can encompass “domestic transactions of

16

any kind.” City of Pontiac Policemen’s & Firemen’s Ret. Sys. v. UBS AG, 752 F.3d 173, 180 (2d

17

Cir. 2014). Thus, even if a “corresponding overseas transaction” was necessary here, “it does not

18

change the fact that a purchase in the United States still took place.” United States v. Martoma,

19

No. 12 CR 973 PGG, 2013 WL 6632676, at *5 (S.D.N.Y. Dec. 17, 2013) (quoting Phelps v.

20

Stomber, 883 F. Supp. 2d 188, 209 (D.D.C. 2012)). Plaintiffs have therefore established the trades

are domestic within the meaning of Toshiba and Morrison.7 Defendants’ counterargument is

Defendants seek leave to file a supplemental report from Mr. Zarcu to respond to “late-breaking
evidence” contained in the Mitts Reply Report. See Dkt. 167. However, Defendants do not appear
to object to the portions of the Mitts Reply Report that are relevant here to answering the
extraterritoriality question (namely, those discussing transfer of title). The motion is thus denied.

Plaintiffs, as well as Dr. Mitts, suggest the fact Bayer ADRs are sponsored should essentially be
dispositive in resolving the domesticity question. They note, for instance, that “courts have
uniformly held that purchases of sponsored ADRs on U.S. OTC markets are domestic transactions
that do not raise extraterritoriality concerns.” Mot., at 11 n.3. While this may be true with respect
to motions to dismiss, this is inaccurate in the class certification context. Indeed, the two cases on

therefore rejected, and its impact (or, rather, lack thereof) on Plaintiffs’ Rule 23 showings is

2

discussed below.

United States District Court
Northern District of California

B. The Rule 23(a) Factors Are Met

4

1. Numerosity

5

The parties do not dispute that the putative class members are sufficiently numerous to

6

warrant certification. Indeed, as Plaintiffs note, the volume of Bayer ADR trades during the Class

7

Period suggests that there are thousands of class members. There are also “at least 178

8

institutional investors” that owned Bayer ADRs during this time. Mot., at 8. The numerosity

9

requirement is thus easily satisfied.

10

2. Commonality

11

The parties similarly do not dispute that there are questions common to the putative class.

12

These include, among others: “(a) whether Defendants violated the Exchange Act; (b) whether

13

Defendants’ statements omitted material facts necessary to make the statements made, in light of

14

the circumstances under which they were made, not misleading;” and “(c) whether Defendants

15

knew or recklessly disregarded that their statements and omissions were false and misleading.”

16

Id. at 9. As in many securities actions, these questions appear capable of classwide resolution.

17

E.g., In re Banc of Cal. Sec. Litig., 326 F.R.D. 640, 646 (C.D. Cal. 2018). Plaintiffs have thus

18

demonstrated that the commonality requirement is met here.

19

3. Typicality

20

Plaintiffs assert their claims are typical of, “if not virtually identical to,” the claims of the

21

absent class members, as they are all predicated on the same alleged misconduct and rely on the

22
23
24
25
26
27

which Plaintiffs primarily rely for this point — In re Volkswagen “Clean Diesel” Mktg., Sales
Pracs., & Prod. Liab. Litig., No. 2672 CRB (JSC), 2017 WL 66281 (N.D. Cal. Jan. 4, 2017), and
Vancouver Alumni Asset Holdings Inc. v. Daimler AG, No. CV 16-02942 SJO (KSx), 2017 WL
2378369 (C.D. Cal. May 31, 2017) — were both decided on motions to dismiss, and both were
decided before Toshiba. Given plaintiffs must clear a higher bar to obtain class certification than
to survive a motion to dismiss, Olean, 31 F.4th at 665; and in light of Morrison’s emphasis on
situs of the transaction versus situs of the misleading conduct, 561 U.S., at 268; the case law does
not appear to imply that an ADR is necessarily traded domestically just because it was sponsored.

same legal theories. Mot., at 9. Defendants argue that Plaintiffs are atypical because they are

2

vulnerable to the “unique and dispositive defense” of extraterritoriality. Opp., at 8. For the reasons

3

discussed above, this argument is unpersuasive and there are no significant extraterritoriality

4

concerns here. Like other securities class actions, Plaintiffs have shown the class members writ

5

large have been “the victim[s] of the same material misstatements and the same fraudulent course

6

of conduct,” rendering Plaintiffs typical. In re Marsh & McLennan Cos., Inc. Sec. Litig., No. 04

7

Civ. 8144(CM), 2009 WL 5178546, at *10 (S.D.N.Y. Dec. 23, 2009).

8

4. Adequacy

9

Finally, Plaintiffs and proposed Class Counsel are adequate to represent the Class.

10

Plaintiffs have all purchased Bayer ADRs and have an adequate stake in seeing this case to

11

resolution, and the proposed Class Counsel has significant experience handling similar actions.

12

Defendants do not dispute this. As such, the adequacy requirement is met here as well.

13

C. The Rule 23(b)(3) Factors Are Met

14

1. Predominance

15

Defendants argue Plaintiffs have not established predominance for three reasons. First,

16

independent of their own extraterritoriality concerns, Plaintiffs have failed to present “a common,

17

class-wide methodology for establishing that other class members purchased their Bayer ADRs

18

domestically.” Opp., at 15. Second, Plaintiffs have failed to show that damages may be calculated

19

on a classwide basis, and that their damages methodology contains several flaws. Third, Plaintiffs

20

cannot invoke the Basic presumption of reliance for the entire Class Period because they have

21

failed to show that “Bayer ADRs traded in an efficient market for a several-week period in June

22

2018.” Id. None of these arguments are persuasive, and Plaintiffs have satisfied their burden to

23

show that common questions predominate over individual ones.

24

a. Extraterritoriality

25

First, as the discussion above illuminates, there is no extraterritoriality problem for

26

Plaintiffs themselves. Defendants are correct to state that any class members who obtained their

27

ADRs in a foreign transaction would not be entitled to recover. Yet, as Dr. Mitts’s report suggests,

28

CASE NO. 20-cv-04737-RS

12

Case 3:20-cv-04737-RS Document 175 Filed 05/19/23 Page 13 of 17

1

and as Defendants concede, the overwhelming majority of all Bayer ADR trades during the Class

2

Period involved existing ADRs. For the minority involving new ADRs, there is no evidence to

3

suggest the same analysis above could not be extended to most (if not all) of the absent class

4

members. As Plaintiffs suggest, if Defendant is able to mount an extraterritoriality defense to any

5

absent class members, this can be handled “in a manner similar to that used when individualized

6

damages inquiries arise in class action proceedings.” Nitsch v. Dreamworks Animation SKG Inc.,

7

315 F.R.D. 270, 313 (N.D. Cal. 2016) (citing Jimenez v. Allstate Ins. Co., 765 F.3d 1161, 1168

8

(9th Cir. 2014)). Further, if at a later point in this case it becomes evident that such individualized

9

inquiries will be necessary, the class definition may be revised or the proceedings bifurcated

10

United States District Court
Northern District of California

11
12

appropriately. In re Petrobas Secs., 862 F.3d 250, 274 (2d Cir. 2017).
b. Damages
Second, Defendants maintain that Plaintiffs have not offered a reliable method to measure

13

damages on a classwide basis. They claim Plaintiffs’ approach is fatally flawed in at least three

14

ways: (1) Plaintiffs have not offered a way to model the degree to which Defendants understated

15

the risk stemming from the glyphosate (“Roundup”) litigation; (2) they do not provide a way to

16

control for investors’ varied expectations concerning the Bayer-Monsanto merger; and (3) they

17

have not presented a method to differentiate between the alleged corrective disclosures and other,

18

equivalent releases of information (including those originating from the Roundup litigation).

19

As an initial matter, it is worth noting that the Ninth Circuit has expressly held district

20

courts should not deny class certification where the putative class “will require determination of

21

some individualized questions at trial” — including, for instance, damages. Olean, 31 F.4th at

22

668. Indeed, a class can be certified with respect to some issues but not others. See id. (citing In re

23

Urethane, 768 F.3d 1245, 1255 (10th Cir. 2014)). Here, numerous common questions, including

24

those surrounding Bayer’s due diligence efforts, its external communications, and the effects of

25

both on the market, clearly predominate.

26
27

Moreover, Defendants’ attacks on Plaintiffs’ damages methodology are premature, and
none warrant denying class certification. Plaintiffs have shown that, contrary to Defendants’

Case 3:20-cv-04737-RS Document 175 Filed 05/19/23 Page 14 of 17

1

assertion, investor uncertainty around the risk posed by the ongoing glyphosate litigation can be

2

factored into the out-of-pocket damages model.8 The same is true regarding investors’ beliefs

3

about the Bayer-Monsanto merger, as well as the impact of the alleged corrective disclosures on

4

the ADR price. In each case, the but-for ADR price (and class members’ damages) would be

5

subject to classwide proof. Indeed, courts have routinely found the out-of-pocket model flexible

6

enough to accommodate such complicating factors. See, e.g., Mulderrig v. Amyris, Inc., 340

7

F.R.D. 575, 589 (N.D. Cal. Dec. 8, 2021); In re Barrick Gold Sec. Litig., 314 F.R.D. 91, 106

8

(S.D.N.Y. 2016). True, Plaintiffs “may face substantial hurdles in actually proving loss causation

9

and out-of-pocket damages.” Id. (quoting Barrick, 314 F.R.D. at 106). Yet the fact that calculating

10

damages is a complex undertaking does not undermine the use of the out-of-pocket model, nor

11

does it militate against certifying the class. Defendants’ arguments, valid though they may be, are

12

thus better left for a later stage of litigation. See SEB Inv. Mgmt. AB v. Symantec Corp., 335

13

F.R.D. 276, 288 (N.D. Cal. 2020).
c. The Basic Presumption of Reliance

14

Finally, Defendants argue Plaintiffs have failed to show that the market for Bayer ADRs

15
16

was efficient for the entire Class Period. Under Basic Inc. v. Levinson, 485 U.S. 224 (1988), a

17

plaintiff seeking class certification may “invoke a rebuttable presumption of reliance based on the

18

fraud-on-the market theory.” Goldman Sachs Grp., Inc. v. Ark. Teacher Ret. Sys., 131 S. Ct. 1951,

19

1958 (2021). This involves proving “(1) that the alleged misrepresentation was publicly known;

20

(2) that it was material; (3) that the stock traded in an efficient market; and (4) that the plaintiff

21

traded the stock between the time the misrepresentation was made and when the truth was

22

revealed.” Id. (citing Halliburton Co. v. Erica P. John Fund, Inc., 573 U.S. 258, 276 (2014)).

23

Defendants here argue that Plaintiffs have failed to satisfy the third element, market efficiency, for

24

a twelve-day period in June 2018, because there was a “large, sustained divergence” between

25
26
27

Separately, it’s not entirely clear why this argument is relevant, since “Plaintiffs have removed
allegations concerning misrepresentations about Bayer’s accounting for legal risks related to
Roundup and no longer seek to proceed on this theory of liability.” Dkt. 122, at 2.

Bayer ADR prices and Bayer regular share prices during this time. Opp., at 22. Such a divergence

2

is also referred to as an “arbitrage opportunity.” Dkt. 141-1 (“Coffman Rpt.”) ¶ 80. This suggests

3

that “the price of Bayer ADRs failed to rapidly incorporate new information” during this period.

Opp., at 22.

5

Proving market efficiency in order to invoke the Basic presumption involves examining

6

multiple factors. Courts in the Ninth Circuit have commonly looked to those outlined in Cammer

7

v. Bloom, 711 F. Supp. 1264 (D.N.J. 1989): (1) “whether the stock trades at a high weekly

8

volume”; (2) “whether securities analysts follow and report on the stock”; (3) “whether the stock

9

has market makers and arbitrageurs”; (4) “whether the company is eligible to file [a short form

10

registration statement with the SEC]”; and (5) “whether there are empirical facts showing a cause

11

and effect relationship between unexpected corporate events or financial releases and an

12

immediate response in the stock price.” Purple Mtn. Tr. v. Wells Fargo & Co., No. 18-cv-03948-

13

JD, 2022 WL 3357835, at *3 (N.D. Cal. Aug. 15, 2022) (alteration in original) (internal quotation

14

marks omitted); see Binder v. Gillespie, 184 F.3d 1059, 1064 (9th Cir. 1999). Some courts also

15

examine the factors listed in Krogman v. Sterritt, 202 F.R.D. 467 (N.D. Tex. 2001), which include

16

market capitalization, the bid-ask spread, and the size of the public float. See Malriat v.

17

QuantumScape Corp., No. 21-cv-00058-WHO, 2022 WL 1794629, at *13 (N.D. Cal. Dec. 19,

18

2022). Plaintiffs here discuss all eight of these factors, as well as four additional factors:

19

ownership by institutional investors; autocorrelation (that is, whether “previous price movement

20

have the ability to predict future price movement”); the amount of options trading; and the lack of

21

arbitrage opportunities. Coffman Rpt. ¶¶ 74–80. In their view, the Bayer ADR market was

22

efficient for the entire Class Period according to at least ten of these factors.

23

Between June 6 and June 25, 2018, there does appear to have been a disparity between the

24

Bayer ADR price and the ordinary Bayer share price. As both Mr. Coffman and Dr. Garmaise

25

discuss, these discrepancies overlap with a period in which BONY announced “a cash distribution

26

for ADR holders that ordinary shareholders were not expecting to receive.” Dkt. 151-1 (“Garmaise

27

Rpt.”) ¶ 91. While the experts disagree about how much this decision would be expected to impact

28

CASE NO. 20-cv-04737-RS

15

United States District Court
Northern District of California

Case 3:20-cv-04737-RS Document 175 Filed 05/19/23 Page 16 of 17

1

the Bayer ADR price, it is apparent that the price discrepancy was due to this external (and

2

somewhat unusual) situation. It was not, in other words, because investors suddenly decided to

3

stop paying attention to market information for two weeks. Even accepting the argument that one

4

of the efficiency factors (lack of arbitrage opportunity) was not satisfied for this period,

5

Defendants have not shown that any of the other factors weigh against overall market efficiency.

6

As Plaintiffs observe, “the relevant question is whether the price of Bayer ADRs ‘reflect[ed] all

7

public, material information.’” Reply, at 15 (alteration in original) (quoting Halliburton, 573 U.S.

8

at 263). Looking at the whole picture, Defendants’ arguments simply do not outweigh the fact that

9

Plaintiffs have convincingly shown market efficiency for the Class Period (including the two

10

weeks in question) under nearly all the Cammer, Krogman, and additional factors. As such,

11

Plaintiffs have established market efficiency such that they may invoke the Basic presumption for

12

the entire Class Period.9

13

2. Superiority

14

In addition, Plaintiffs assert (and Defendants do not deny) that the class device is the

15

superior vehicle for resolving the claims in this case. The volume and complexity of the claims

16

make the case readily amenable to classwide resolution, and judicial economy would be enhanced

17

through consolidated litigation. There is no indication that any class members would prefer

18

individual litigation; indeed, the limited size of any potential recovery for individual class

19

members suggests the class device is the only practical way to obtain relief. Thus, the superiority

20

requirement is also met here.
V. CONCLUSION

21

Plaintiffs have met all of the requirements of Rule 23(a) and Rule 23(b)(3). As such, the

22
23

motion is granted, and the following class is certified:

24
25
26
27

9

Plaintiffs point out that the time period Defendants flag represents less than 2% of the entire
Class Period. Reply, at 15. Even so, if the market was inefficient for this time, the proper recourse
would appear to be to excise that portion from the Class Period — but not, as Defendants suggest,
to deny class certification. See In re LDK Solar Sec. Litig., 255 F.R.D. 519, 530 (N.D. Cal. 2009).
