Filings
| Agency | Record date | People | In total | Days to notice | Links |
|---|---|---|---|---|---|
| Oregon Oregon DOJ | Apr 20, 2018 | 17,902 (total) | 10 days, statute 45 days | Record | |
| California California AG | Apr 20, 2018 | Not published | 10 days, statute 30 days | Letter Record |
People is the count the filing gives, residents of the state unless marked total. Days to notice runs from the discovery date the letter states, or from the end of the breach window when no letter states one, to the date on the state's first record of the incident. "Over" marks a count past the days the state's statute allows for notice to residents. The statute's trigger is a question of fact, the days are arithmetic.
