The award consists of 6,250 RSUs and an additional 37,500 RSUs reported as a derivative award; both were recorded at $0.00 per share (no cash paid).

Context
RSU grants are a common form of equity compensation for executives and directors. They represent a future right to receive shares if vesting conditions are met and do not indicate an immediate buy or sell decision by the insider. The 37,500 RSUs reported as a derivative simply reflect contingent stock awards that will convert to shares upon settlement/vesting per the plan terms.
