Public Methods
 NameDescription
Public Method (Inherited from System.ServiceModel.ClientBase<IMarginalImpactService>)
Public Method (Inherited from System.ServiceModel.ClientBase<IMarginalImpactService>)
Public Method (Inherited from System.ServiceModel.ClientBase<IMarginalImpactService>)
Public MethodRetrieves a list of all user-defined administrative boundaries in a given Business Unit and SQL Server Instance.  
Public MethodRetrieves a set of Touchstone® Marginal Impact Analysis Results.

The Marginal Impact Analysis results set contains a group of Marginal Impact Results for each relevant Region Peril Set that you specified when configuring the Marginal Impact Analysis. Marginal Impact results include the following information:

  • Aggregate and occurrence results for the reference Portfolio
  • Aggregate and occurrence results for the new Contract/Portfolio
  • Aggregate and occurrence Portfolio impacts
  • Aggregate and occurrence Marginal impact

Each group of Marginal Impact Results within a Marginal Impact Results set contains the following data:

  • Average annual loss (AAL)
  • Standard deviation (SD)
  • Exceedance Probability (EP) points
 
Public MethodRetrieves a list of contract identifiers for the expiring contracts included in a set of loss analysis results.

If you specified a contract in the ExpiringContractID field of a different contract, Touchstone returns the first contract as an expiring contract. During a marginal impact analysis, you can optionally exclude losses from expiring contracts.

 
Public MethodRetrieves a set of administrative boundary groups saved as a marginal impact analysis template.  
Public MethodRetrieves a list of all marginal impact analysis templates in a given Business Unit and SQL Server Instance. Each template is a saved set of administrative boundary groups.  
Public Method (Inherited from System.ServiceModel.ClientBase<IMarginalImpactService>)
Public MethodSubmits a new Touchstone® Marginal Impact Analysis job.

A Marginal Impact Analysis enables you to view the effect that a specific loss results set (the target or new Portfolio/Contract) has on another loss results set (the Reference Portfolio). For example, an underwriter may want to assess the potential consequences of adding a new Contract or Portfolio to an existing Portfolio.

Marginal Impact combines two loss results sets, providing users with two outputs, one for Portfolio Impact and another for Marginal Impact. Touchstone stores summary EP data (aggregate and occurrence), event totals, and distribution based on the geographic resolution used to save the loss results, for both sets of impact results. You can use the Portfolio Impact results to determine capacity and the Marginal Impact results to determine pricing.

The calculation for the Portfolio Impact is equal to (Reference + New), while the calculation for the Marginal Impact is equal to (Reference + New) - Reference. (The calculation for Marginal Impact is not a mathematical formula and is, therefore, not equal to "New.")
