Facts

TGS discovered unusually rich drilling results at its Kidd 55 property in Ontario beginning with drill hole K-55-1 on November 12, 1963, and kept the results confidential while acquiring surrounding land. During the period of nondisclosure, several TGS insiders bought TGS stock or calls, one insider passed information to outsiders who traded, and several officers accepted stock options without disclosing the drilling information to the option committee or board. On April 12, 1964, TGS issued a press release minimizing rumors of a major discovery even though management knew of highly favorable drilling progress through April 10. Before the official public announcement on April 16 was fully disseminated, Clayton, Crawford, and Coates traded, and Coates also passed the information to his broker son-in-law, whose customers traded as well.

Issue

Whether undisclosed drilling results at Kidd 55 were material inside information so that persons possessing them had to disclose or abstain from trading or tipping under Section 10(b) and Rule 10b-5. Also, whether trading before the April 16 announcement was effectively disseminated violated the Rule, whether acceptance of stock options without disclosure to the issuer violated the Rule, and whether TGS's April 12 press release could violate Rule 10b-5 absent proof of insider trading or wrongful motive.

Rule

Anyone possessing material inside information intended only for a corporate purpose must either disclose it to the investing public or abstain from trading in or recommending the securities while the information remains undisclosed. Materiality depends, in event-driven cases, on balancing the probability that the event will occur against the anticipated magnitude of the event in light of the totality of the company's activity; a fact is material if a reasonable investor would attach importance to it and if it might affect the value of the stock. Rule 10b-5 also reaches tipping, acceptance of stock options by top management without disclosure of material information to the issuer, and corporate statements made in a manner reasonably calculated to influence investors if they are false, misleading, or so incomplete as to mislead; in an SEC injunctive action, negligent conduct and lack of due diligence are sufficient.

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

Blue Mesa Minerals, a publicly traded mining company based in Denver, learns from its exploration team that an initial drill core in Nevada shows unusually rich mineralization. Management keeps the result confidential for several weeks while the company quietly negotiates leases on nearby parcels. During that period, senior geologist Elena Park buys 4,000 shares of Blue Mesa stock in her personal account.

If the drill-core information would have mattered to a reasonable investor, is Elena's purchase most likely a violation of Rule 10b-5 in an SEC enforcement action?

Explanation. The majority held that anyone with access to material inside information intended only for a corporate purpose must either disclose it to the investing public or abstain from trading. A legitimate corporate reason for keeping the information confidential does not allow personal trading during the period of nondisclosure. The rule is not limited to formal insiders such as directors; it also reaches employees possessing the information.
