The Oregon Insurer Notice of Closure Worksheet (Dates of Injury On or After January 1, 2005) is a document that must be completed by insurers when closing a workers' compensation claim in the state of Oregon. It is designed to provide a standardized method of notifying employees, injured workers, and other parties of the claim closure and to provide a summary of the claim closure information. The worksheet allows insurers to provide a basic description of the injury and the date of injury, a brief summary of the claim closure, and the amount paid for the claim. The worksheet also provides information about the insurer's reserves, total incurred, and total paid on the claim. Different types of Oregon Insurer Notice of Closure Worksheets include: Notice of Closure for Claims With Dates of Injury On or After January 1, 2005, Notice of Closure for Claims With Dates of Injury Before January 1, 2005, and Notice of Closure for Claims With Dates of Injury On or After January 1, 2005, and Before January 1, 2005.
