In the third quarter of each year, we conduct our asbestos remeasurement to review and update the underlying assumptions used in our asbestos liability and related asset estimates and to determine the cost the Company estimates will be incurred to resolve all pending claims, as well as unasserted claims estimated to be filed over the next 10 years. In each remeasurement, the underlying assumptions are updated based on actual experience since the previous annual remeasurement and we reassess the appropriate reference period of years of experience used in determining each assumption and our expectations regarding future conditions, including inflation.
