Facts

Four-Phase stock experienced a sharp rise in price and trading volume, prompting inquiries from the New York Stock Exchange. In response, Four-Phase publicly stated on December 2, 1981 that the company was 'not aware of any corporate developments which would affect the market of its stock.' At that time, Four-Phase had been engaged for months in ongoing merger discussions and negotiations with Motorola, including recent high-level meetings on November 23 and 24. Plaintiff alleged that news of those negotiations had leaked into the market, that the December 2 statement was false or misleading, and that class members sold stock before Four-Phase later announced a merger agreement with Motorola.

Issue

Whether defendants were entitled to summary judgment on the ground that the December 2 statement was not materially false or misleading and that defendants lacked scienter. More specifically, the question was whether an issuer that chose to respond publicly to unusual market activity had a duty to make a truthful and complete statement regarding known material facts, and whether the record conclusively negated fraudulent intent or recklessness.

Rule

An issuer has no general duty to disclose inchoate merger negotiations when it is not trading in its own securities, but if it chooses to make a public statement, it must disclose all material facts necessary to make the statement made, in light of the circumstances, not misleading. Materiality turns on whether there is a substantial likelihood that the fact would have assumed actual significance to a reasonable investor or significantly altered the total mix of information. Scienter under § 10(b) and Rule 10b-5 may be established by reckless conduct where defendants owe a fiduciary duty to sellers of securities, and reliance on advice of counsel does not excuse a violation if one occurred.

One of 10 multiple-choice questions for this case. Pick an answer to see why.

North Harbor Robotics, a publicly traded company based in Seattle, has been in active acquisition talks for several months with a larger manufacturer. After a sharp spike in trading volume and price, the exchange calls the company to ask whether management knows of any corporate developments affecting the stock. The company then issues a public wire statement saying it is 'not aware of any corporate developments affecting trading in its shares,' even though senior officers know the talks are ongoing and know of no other event explaining the trading surge.

If investors who sold after the statement sue under Rule 10b-5, which is the strongest argument against summary judgment for the company?

Explanation. The majority opinion drew a sharp distinction between silence and speech. It recognized no general duty to disclose inchoate merger negotiations when the issuer is not trading in its own securities, but held that once the issuer voluntarily makes a public statement, it must disclose all material facts necessary to keep that statement from being misleading in light of the circumstances. Ongoing high-level negotiations and the lack of any other known explanation for unusual market activity make summary judgment inappropriate.
