The Proposed Update includes common reporting practice for disclosure requirements in IFRS 13, such as:

• sensitivity of fair value measurement to changes in unobservable inputs; and
• quantitative information about significant unobservable inputs used in fair value measurement.

Following the public comment period for a proposed update, a taxonomy update is issued. The annual IFRS Taxonomy, which is published in the first quarter of the year, is the cumulative collection of these updates. 

The public comment period for this Proposed Update will end on November 19, 2018. Comments should be directed to the IFRS Foundation. SEC filers, investors, analysts, software developers, and other interested parties are encouraged to participate in the public review to continue to improve the process for creating and using XBRL financial statements.

Please note: only annual compilations of the IFRS Taxonomy specified directly on the SEC’s website may be used in SEC XBRL submissions. The public comment period for this Proposed Update to the 2018 IFRS Taxonomy does not indicate the SEC’s approval of any potential regulatory changes related to the EDGAR Filer Manual.
