Do Trades Made Pursuant to 10b5-1 Plans Still Offer A Defense to Insider Trading?

Chairs Around a Table

Rule 10b5-1, enacted in August 2000, codified the SEC’s position that trading while in possession of material non-public information is sufficient to establish liability for insider trading. The rule also provided an affirmative defense for individuals who could prove that the purchase or sale of stock was made pursuant to a pre-existing written plan executed before the individual became aware of the material non-public information. These so-called 10b5-1 plans have long been considered to be an efficient way to trade company stock without raising suspicion of insider trading or another improper motive.

However, recent news stories have reignited concerns that corporate insiders may be abusing 10b5-1 trading plans to trade on material non-public information. An April Wall Street Journal article reported that not only has the use of 10b5-1 plans by non-executive directors nearly doubled between 2006 and 2011, but a significant percentage of the plans were being used to unload all or a large percentage of the directors’ holdings in a short period of time. An earlier November 2012 Wall Street Journal article analyzing thousands of trades made by corporate executives found evidence that company insiders did statistically much better than expected in realizing trading profits. Together, these articles suggest that the lack of transparency and regulation of 10b5-1 trading plans has allowed them to be misused as vehicles to effectuate opportunistic trades.
