The filing reports an acquisition at $0.00 per unit (grant), which reflects an award rather than a cash purchase; no cash changed hands in this transaction.

• Price reported: $0.00 per unit (standard for RSU grants); reported acquisition = 2,558 RSUs.

Context

• RSU grants are a common form of executive/director compensation and do not represent a market purchase or sale. They generally indicate company compensation policy rather than a direct trading signal. If and when the RSUs vest, Dirkson will receive shares (which could be sold or held), at which point future filings would show any subsequent sales or withholding for taxes.
