Insights

Corporate Governance Expert

TL;DR: Routine director deferral into promised fee shares; no disposals and ownership remains disclosed.

The filing documents a director-level, non-derivative recording of 324 Promised Fee Shares under IBM's director deferred compensation plan. This is an administrative reporting of deferred compensation conversion into promised equity units payable at retirement, not an open-market purchase or sale. It increases disclosed direct beneficial ownership to 2,947 shares. For governance review, this is a standard equity-based deferral consistent with typical board compensation mechanisms and poses no immediate liquidity or control change based on the information provided.

Securities Analyst

TL;DR: Form 4 records a deferred-compensation credit of 324 equity units, with no market transaction disclosed.

From a securities-disclosure perspective, the Form 4 clarifies the nature and amount of equity attributable to the reporting person: 324 Promised Fee Shares at a referenced fee/share of $282.16, and total direct beneficial ownership of 2,947 shares. The transaction code indicates deferral under the director deferred compensation plan rather than an open-market trade, so there is no immediate change in outstanding public float or trading volume from this filing alone. Materiality to investors is limited absent additional context on shareholding thresholds or subsequent transactions.
