Poliner Graham 4

What Happened Graham Poliner (listed as CSBIAO) had shares withheld to satisfy tax obligations following option-related transactions. The filing shows three tax-withholding dispositions: 218 shares at $227.42 ($49,578), 442 shares at $227.42 ($100,520), and 103 shares at $227.42 ($23,424) — a total of 763 shares withheld and a cash value of $173,522. These entries are recorded as "F" (payment of exercise price or tax liability) and "Disposed," meaning shares were surrendered/withheld to cover taxes rather than sold on the open market.

Context These are not open-market sales but tax-withholding dispositions tied to an option exercise or similar equity event (a common, administrative step when insiders exercise options). Such withholdings are routine and do not necessarily indicate a directional view of the stock — they simply settle tax liabilities arising from the exercise.
