Changes in vulnerability component of commercial residential low-rise model
The CR-LR model has new interior and contents damage models, which computes the rainwater induced damage to each interior component and contents.
The new interior damage model leads to a revised cost analyses of the low-rise models.
The model generates separate contents vulnerability curves for an overall building, an apartment building, and a condominium association building. In the past, it did not differentiate between the three.
The model has updated the formula to compute time-related expenses for apartment buildings.
Changes in vulnerability component of commercial residential mid/high-rise model.
The FPHLM has an improved interface between Personal Residential portfolios with condo units (owners or rentals) and the MHR model.
The FPHLM runs the model for both open and closed layouts and calculate the weighted average of the losses from both runs.
The model makes-up for missing data on building geometry (# of stories, building area, # of units per story) in a way consistent with the information available in the portfolio (insured value of the building and location).
The model benefits from an updated cost analysis.
The model now computes the insured losses differently for apartment buildings (AB) and condo associations (CA). In the past CR-MHR were assumed to be CA by default.
Changes in Treatment of Apartment Building vs Condominium Association in commercial residential model.
The model has separate equations to transform the building damage into insured losses for either apartment building (AB) or condominium association (CA).
In the past CR-LR policies were assumed to be apartment buildings by default. Now, the model processes the CR-LR policies as both AB and CA, and produces a weighted average of the two. The statistical distribution of AB and CA within the insurance portfolios, for each county, defines the weights.
