Context

• Sales under a 10b5-1 plan are typically prearranged and may be routine (e.g., for diversification or liquidity) rather than signaling a change in the insider’s view of the company. As a 10% owner (not necessarily an officer), Calkins’ trades are reportable under Section 16 but should be interpreted with the plan context in mind.
