Exposure Variations

Understand exposure variations

Overview

An exposure variation is an immutable snapshot of an account, aggregate portfolio, or portfolio exposure.

Exposure Variations enable tenants to better manage exposure data by ensuring that analyses, reports, and data exports accurately reflect the state of an exposure at a particular point-in-time.

Whenever the Intelligent Risk Platform performs an analysis of an exposure and generates an analysis, it automatically creates an immutable point-in-time snapshot of that exposure and its data, called an exposure variation.

Exposure Variation Versions

The Intelligent Risk Platform supports two versions of exposure variations:

  • An exposure variation (version 1) can be used to model accumulations.
  • An exposure variation (version 2) can be used to model accumulations or exposures using ALM, DLM, or HD models.

Version 1

The Variation API supports the creation and management of exposure variations (version 1).

Exposure variation (v1) support accumulation analysis. This version of exposure variation does not support ALM, DLM, or HD analysis.

Accumulation analysis based on an exposure variation (v1) enable tenants to ensure that accumulation analysis jobs are based on the same data, regardless of the time between analyses. To learn more, see Accumulation API Overview.

Version 2

The Risk Data API and Import API support the creation and management of exposure variations (version 2).

Exposure variation (v2) support accumulation, ALM, DLM, and HD analysis.

Exposure Variation Store

The Exposure Variation Store is a tenant space on Amazon S3 that stores exposure variations in Parquet format.

For each EDM Database table, the table links to EDM Database Schema documentation in Help Center.

The following tables must be uploaded to create an account variation: accgrp, address, dbattribute, policy, property, rmsver

Aggregate Portfolio

An aggregate portfolio is a collection of exposure values aggregated by geographic unit (e.g. CRESTA) or by line of business (e.g. Commercial). An aggregate portfolio is defined by a cedant peril, and other attributes.

At a minimum, files containing the following data must be uploaded:

The following tables must be uploaded to create an aggregate portfolio variation: agexpos, agport, dbattribute, rmsver

Portfolio

A portfolio is a type of exposure that represents a collection of accounts, along with the associated treaties and facultative cessions.

At a minimum, files containing the following data must be uploaded:
