California Water Service Group
A regulated water utility holding company, the largest of its kind in the western United States, that produces, treats, and delivers drinking water to homes and businesses while also handling wastewater. Known as "Cal Water," it was founded in 1926 by three World War I veterans who started by consolidating water systems in the four California towns of Chico, Visalia, Bakersfield, and Fresno. Its parent holding company, California Water Service Group, was created in 1997 to help the utility expand into other states.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -65.5K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
