How many Bank of Marin Bancorp (BMRC) shares did the CFO acquire?

The CFO acquired 7,291 shares of BMRC common stock through a grant or award. This non-cash acquisition increased his direct ownership to 18,338 shares immediately after the award, according to the reported post-transaction share balance.

What does the Form 4 tax-withholding disposition mean for BMRC CFO’s shares?

The reported BMRC insider transactions were not open-market trades. One entry records a grant or award of 7,291 shares, and the other is a tax-withholding disposition of 278 shares used to satisfy tax obligations, not a discretionary market sale.

How many BMRC shares does the CFO own after these Form 4 transactions?
