The filing documents a purchase of 11 common shares at $33.13 each by Director Jill Bourland, increasing her reported direct beneficial ownership to 5,520.0148 shares. The entry uses transaction code V and no options, warrants, or other derivative instruments are shown. Given the small share count relative to typical bank market caps, this transaction is likely immaterial to ISBA's capital structure or share supply.
