Known Issue 350

Building (Coverage A) losses for a location may be misstated in the Japan, Caribbean and Australia earthquake models when that location has different values in the Construction Building and Construction Other Structures fields and the Stories field is unknown.

Issue ID	350
Summary	Building (Coverage A) losses for a location may be misstated in the Japan, Caribbean and Australia earthquake models when that location has different values in the Construction Building and Construction Other Structures fields and the Stories field is unknown.
Description	Touchstone is incorrectly revising the unknown height formulation for Building losses when the Construction Building is not equivalent to the Construction Other Structures field and the Stories field is unknown. In certain circumstances, this will result in an inaccurate Building (Coverage A) loss for that location. Note that this is only possible when an exposure has an explicit value imported in the Construction Other Structures field that is different than the Construction Building Field. This error was introduced when the models were most recently updated, which was the 2020 (v8.0) release for the Caribbean and Australia Earthquake models and the 2021 (v9.0) release for the Japan Earthquake model.
Resolved in	Touchstone 2024
Date posted	11/22/2022
Software versions affected	12.0, 11.5, 11.2, 10.0, 9.1, 9.0
Feature set	Detailed loss
Models	Verisk Earthquake Model for Australia, Verisk Earthquake Model for Caribbean, Verisk Earthquake Model for Japan
Potential for loss numbers impact	Yes
Workaround	For locations where Construction Building is different than Construction Other Structures, import as two separate locations.
