The dissenting opinions stated that Dirks was under an obligation either to make the
REASONING: The duty to disclose under Rule 10b-5 is not automatic when one merely possesses inside
information. The duty to disclose arises when there exists a fiduciary relationship, something
that was not present in Dirks. When an accountant, lawyer, or consultant working for a
company receives corporate information, these professionals may become fiduciaries of the
shareholders since they have a confidential relationship with the company. Thus unlike Dirks,
who was not an employee of Equity Funding, such professionals can be held liable for what
Dirks was accused of.
DISCUSSION POINTS: Have the students discuss the Dirks v. SEC case that illustrates the rule that when the
insider does not breach a fiduciary duty, a tippee does not violate securities laws.
e. Misappropriation theory of insider trading
CASE BRIEF: United States v. O’Hagan
521 U.S. 657 (1997)
FACTS: James O’Hagan was a partner in the law firm of Dorsey & Whitney in Minneapolis, Minnesota.
In July 1988, Grand Metropolitan PLC, a company based in London, England, retained Dorsey
& Whitney as local counsel to represent Grand Met regarding a potential tender offer for the
common stock of the Pillsbury Company, headquartered in Minneapolis. O ’Hagan did no work
on the Grand Met representation. Dorsey & Whitney withdrew from representing Grand Met on
September 9, 1988. Less than a month later, on October 4, 1998, Grand Met publicly
announced its tender offer for Pillsbury stock. On August 18, 1988, while Dorsey & Whitney was
still representing Grand Met, O’Hagan began purchasing call options for Pillsbury stock. Each
option gave him the right to purchase 100 shares of Pillsbury stock by a specified date in
September 1988. Later in August and September O’Hagan purchased additional Pillsbury call
options. By the end of September he owned 2,500 unexpired Pillsbury options, apparently more
than any other individual investor. O’Hagan also purchased, in September 1988, some 5,000
shares of Pillsbury common stock, at a price just under $39 per share. When Grand Met
announced its tender offer in October, the price of Pillsbury stock rose to nearly $60 per share.
O’Hagan then sold his Pillsbury call options and common stock, making a profit of more than
$4.3 million. O’Hagan was charged and convicted of securities fraud in violation of section
10(b) and Rule 10b-5. On appeal he claimed that he was not a fimisappropriator, ” for he had no
fiduciary duty to the Pillsbury shareholders from whom he purchased calls and stock; in fact, he
had not even worked on the transaction at the law firm.
ISSUE: Did O’Hagan violate 10b?
REASONING: fiMisappropriation” requires that there be fideceptive” conduct fiin connection with” a securities
transaction. A fiduciary who pretends loyalty to the principal while secretly converting the
principal’s information for personal gain dupes or defrauds the principal. O ’Hagan’s failure to
disclose his personal trading to his law firm and its client, Grand Met, was a breach of his
fiduciary duty and was fideceptive ” conduct fiin connection with” a securities transaction. The
misappropriation theory is designed to protect the integrity of the securities market against
fioutsiders” like O’Hagan, who have access to confidential information that will affect a
company’s stock price when revealed but have no fiduciary or other duty to the company ’s
shareholders.
DISCUSSION POINTS: Have the students discuss the United States v. O’Hagan case regarding outsiders who
have access to confidential information that will affect a company’s stock price.
