Reducing Rating Management components

Rate books, rate table definitions, rate routines, and parameter sets are Rating Management components. There are several ways to reduce Rating Management components in your implementation.

Rating Management component applies to all

You can define Rating Management components with policy line, underwriting company, jurisdiction, or offering that applies to all by specifying <applies to all>. For example, you can define a rate routine that applies to all underwriting companies.

For each rating management component, the following table shows which properties can apply to all. The table also lists examples in the sample data that apply to all.

Rating Management component	Properties that can apply to all...	Example in sample data
Rate book	Policy Line Underwriting Company Jurisdiction Offering	Generic RTM Demo Rating Code: `gx_rtm_demo_rating`
Rate table definition	Policy Line	GenericStateTax Code: `gx_state_tax`
Rate routine	Policy Line Jurisdiction	Generic State Tax Calculation Code: `gx_state_tax_rr`
Parameter set	Policy Line	State Tax Parameter Set Code: `GenericStateTaxParamSet`

Policy line applies to all

Rating Management components can apply to a specific policy line, such as the Personal Auto line of business. Alternatively, Rating Management components can apply to all policy lines, when you set the Policy Line to <applies to all>. In code, if a component applies to all policy lines, the policy line is null.

Line-specific Rating Management components can reference Rating Management components that apply to all policy lines as well as components defined for the same policy line. For example, a rate book with Personal Auto as its policy line can reference rate tables that apply to all policy lines and Personal Auto rate tables. The Personal Auto rate book cannot reference Commercial Property rate tables.

Rating Management components that apply to all policy lines can only reference components that apply to all policy lines. They cannot reference Rating Management components defined for a specific policy line. For example, a rate book that applies to all policy lines can only reference rate tables that apply to all policy lines. The rate book that applies to all policy lines cannot reference Commercial Property rate tables.

Combine similar rate routines and parameter sets

Parameter set wrappers enable you to combine similar parameter sets and rate routines.

You can use wrappers for accessing parameters in a line of business that typed differently. For example, a single parameter set can uses a wrapper to select the coverage by some characteristic of the policy. Wrappers are implemented in Gosu code.

In addition, rate routines that are essentially the same can be combined into a single rate routine by using a parameter set with wrappers.

The sample data has examples using wrappers including:

Rating object	Name	Code
Parameter set	CP Coverage Parameter Set With Wrapped Coverages	`CPCoverageWrapperParamSet`
Rate routine	CP Coverage Premium Algorithm	`cp_cov_premium_rr`
