Form 4 raw → Raspberry

The value is in what we do not call a signal.

The SEC XML stores every transaction. Raspberry keeps that evidence, reads the footnotes and separates voluntary open-market activity from vesting, option exercises, gifts, tax withholding, stock purchase and dividend reinvestment plans and pre-programmed 10b5-1 trades.

Each deferred stock unit ("DSU") represents a contingent right to receive one share of the Issuer's Common Stock. As part of the Issuer's non-employee director compensation program, the reporting person elected to receive his quarterly cash board retainer fee in the form of DSUs pursuant to a prior election under the Issuer's Deferred Compensation Plan for Non-Employee Directors. The number of DSUs was calculated by dividing the quarterly cash retainer amount deferred by $36.35, the Fair Market Value of a share of the Issuer's Common Stock on the effective date of the deferral. The DSUs are fully vested when granted and will be settled in a lump sum in whole shares of the Issuer's Common Stock, with cash paid in lieu of any fractional DSU, following the reporting person's separation from service, disability, or death.
