Short-duration Insurance Contracts

(Taxonomy Version 2017^†)

FASB U.S. GAAP Financial Reporting Taxonomy (Taxonomy)

Implementation Guide Series

† Changes from the 2016 version of this Implementation Guide are included in Appendix A to this Guide.

The Taxonomy Implementation Guide is not authoritative; rather, it is a document that communicates how the U.S. GAAP Financial Reporting Taxonomy (Taxonomy) is designed. It also provides other information to help a user of the Taxonomy understand how elements and relationships are structured.

Taxonomy Implementation Guide on Modeling Short-duration Insurance Contracts

Overview

The purpose of this Taxonomy Implementation Guide is to demonstrate the modeling of disclosures for short-duration insurance contracts. The examples in this Taxonomy Implementation Guide are not intended to encompass all of the potential modeling configurations or to dictate the appearance and structure of an entity’s extension taxonomy. The examples are provided to help users of the U.S. GAAP Financial Reporting Taxonomy (Taxonomy) understand how the modeling for short-duration insurance contracts is structured within the Taxonomy. The examples are based on the assumption that the entity meets the criteria for reporting short-duration insurance contracts under U.S. GAAP and/or Securities and Exchange Commission (SEC) authoritative literature. In addition, the reported line items within the examples are not all inclusive and represent only partial statements for illustrative purposes.

While constituents may find the information in this guide useful, users looking for guidance to conform to SEC XBRL filing requirements should look to the SEC EDGAR Filer Manual and other information provided on the SEC’s website at xbrl.sec.gov.

This guide focuses on detail tagging only (Level 4); it does not include any elements for text blocks, policy text blocks, and table text blocks (Levels 1 through 3).

The Taxonomy Implementation Guide includes the following three examples:


•	Example 1—Disclosure of Information about the Liability for Unpaid Claims and Claim Adjustment Expenses


•	Example 2—Reconciliation of the Disclosure Claims Development to the Liability for Claims and Claim Adjustment Expenses


•	Example 3—Information about Historical Claims Duration

General Information


(1)	A legend for dimensions and domain members has been provided to associate with facts contained in the notes to the financial statements. Extension elements are coded using “Ex.” Legends specific to the examples are provided in Figure x.2 of each example.

M13	Other Short-duration Insurance Product Line [Member]	OtherShortdurationInsuranceProductLineMember
M14	Financial Guarantee Insurance Product Line [Member]	FinancialGuaranteeInsuranceSegmentMember


(2)	Elements that have an instant period type and elements that have a duration period type are indicated as such in Figure x.2 of each example. Instant elements have a single date context (such as December 31, 20X1) while duration elements have a starting and ending date as their context (such as January 1, 20X1 to December 31, 20X1).


(3)	Instance documents (Figure x.3 in each example) do not include all the information that may appear in an entity’s instance document. The instance documents are provided for illustrative purposes only.


(4)	For elements contained in the Taxonomy, the standard label is as it appears in the Taxonomy. For extension elements, the standard label corresponds to the element name. For information about

structuring extension elements, refer to the EDGAR Filer Manual.


(5)	Values reported in XBRL are generally entered as positive, with the exception of certain concepts such as net income (loss) or gain (loss).

Example 1—Disclosure of Information about the Liability for Unpaid Claims and Claim Adjustment Expenses

This example illustrates the modeling of the disclosure for claims development information about the liability for unpaid claims and claim adjustment expenses for short-duration insurance contracts.

•	There is not an XBRL calculation relationship provided for the reconciliation as the calculation would need to subtract an element with the same balance attribute or add an element with a different balance attribute which is not possible under current constraints as shown below:
