Material Nonpublic Information (MNPI)

Now that you understand what insider trading is, the critical question becomes: what information qualifies as MNPI? Both words ("material" and "nonpublic") must apply for the information to trigger insider trading liability.

The Two-Part Test

Material

  • Information is material if a reasonable investor would consider it important in making an investment decision
  • Another way to think about it: would this information likely affect the security's price if it became public?

Nonpublic

  • Information is nonpublic if it has NOT been widely disseminated to the general investing public
  • "Widely disseminated" means the information must be available to the public through recognized channels (press releases, SEC filings, major news outlets)

Think of it this way: "Material" asks whether the information matters. "Nonpublic" asks whether the world knows about it yet. If the answer is "yes, it matters" and "no, the world does not know," you are looking at MNPI.

Examples of Material Information

CategoryExamples
Financial resultsEarnings reports before release, significant revenue changes
Corporate transactionsMergers, acquisitions, tender offers
Business developmentsNew product launches, major contracts, patent approvals
Legal/regulatorySignificant lawsuits, SEC investigations, regulatory actions
Management changesCEO resignation, board member appointments
Capital structureDividend changes, stock splits, share buybacks
Financial conditionImpending bankruptcy, significant debt changes

When Does Information Become Public?

Information becomes public when TWO conditions are met:

  1. Widely disseminated: released through channels accessible to the general public
  2. Market absorption: enough time has passed for the market to digest and react to the information

Exam Tip: Gotchas

  • A press release issued 5 minutes ago may still be "nonpublic." Publication alone is not enough. The market needs time to absorb it.

How to Evaluate MNPI on the Exam

Ask two questions:

  1. Would a reasonable investor care? If yes, it is material
  2. Has the public had access AND time to absorb it? If no, it is nonpublic

If both answers indicate material AND nonpublic, trading on it is prohibited.

Exam Tip: Gotchas

  • Not all inside information is material. The CEO's lunch plans are nonpublic but not material.
  • Not all material information is nonpublic. Published earnings reports are material but already public.
  • BOTH conditions must be met. Information must be material AND nonpublic to trigger insider trading liability.
