Sustainability and climate issues remain in the headlines in the US and Europe. US Treasury Secretary Janet Yellen gave a compelling speech this month outlining Treasury’s “whole-of-government” approach to climate change, emphasizing the importance of ESG data, and Treasury’s intent to work with the Securities and Exchange Commission (SEC) to ensure an effective approach to disclosures:

“Reliability of climate-related disclosures is the threshold issue. Investors fundamentally need accessible and credible information to be able to properly assess the risks and opportunities. We also need consistency of reporting frameworks across sectors, as well as comparability across jurisdictions. Different reporting frameworks reduce the effectiveness of data, making it challenging or impossible for investors to make informed decisions…. the SEC is currently reviewing its 2010 guidance on climate-related disclosures. Treasury will work with the SEC as part of its participation in international discussions to promote effective and consistent approaches to disclosure.”

Separately, the European Commission (EC) announced a package of sustainability-related measures including the Corporate Sustainability Reporting Directive (CSRD) proposal which aims to make corporate reporting of sustainability measures more consistent, comparable and reliable. The CSRD, as proposed, requires the use of Inline XBRL for the reporting of environmental, social and governance (ESG) disclosures as noted in this Impact Assessment.

Gary Gensler confirmed as Chair of the Securities and Exchange Commission. Chair Gensler was sworn into office by U.S. Senator Ben Cardin on April 17, 2021. Most recently, Gensler was Professor of the Practice of Global Economics and Management at the MIT Sloan School of Management, Co-Director of MIT’s Fintech@CSAIL, and Senior Advisor to the MIT Media Lab Digital Currency Initiative. Shortly after his confirmation, Chair Gensler announced appointments of senior staff members.

Forbes article gives SEC gets high marks on modernization, names XBRL as a “laudable stride in improving search and analysis capabilities. The article, The SEC’s Technology Modernization Is Accelerating – Are You Ready? is authored by Jim DeLoach who states, “…the SEC has notched significant progress adjusting rules and enforcement in response to technological disruptions over the past two decades. For example, the commission’s 2009 rule requiring the use of eXtensible Business Reporting Language (XBRL) and its 2018 update of that rule (calling for the use of the Inline XBRL format that makes the disclosure document human- and machine-readable) represent laudable strides in improving search and analysis capabilities…

Thanks to those XBRL rules that place all filings on a common platform, the SEC has amassed a robust database. SEC commissioners have signaled that they plan to intensify their use of data analytics. By mining that database for exceptions and patterns, the SEC can identify trends and anomalies that drive consistent and focused comment

XBRL US Data Quality Committee (DQC) published its 15th ruleset for both US GAAP and IFRS filers. Issuers, accounting professionals and data users are encouraged to review the proposed rules during the public review period which ends June 2.

A subset of the DQC rules has been incorporated into the 2021 US GAAP Taxonomy and filers will be alerted by the SEC’s EDGAR system when these rules are triggered by errors in their filing. This process is explained in the March 2021 EDGAR Filer Manual, “EDGAR will support new data-quality enhancing checks included by FASB in the US-GAAP 2021 taxonomy. Its DQC Rules Taxonomy (DQCRT) was developed through public review in collaboration with market participants via the XBRL US Data Quality Committee (DQC). EDGAR will inform filers of certain quality defects via warning messages.”

Issuers can catch and resolve these errors before SEC submission by using the DQC rules, either by using software that has been certified to run the rules, or by using a checking tool provided by XBRL US. Learn more about the rules and SEC interaction at a May 12 webinar.

SEC requests comment on proposed data collection from credit rating agencies. Credit rating agencies, also called NRSROs (Nationally Recognized Statistical Rating Organizations) are required to disclose credit rating histories in XBRL format using the SEC’s Record of Credit Rating Taxonomy. This request asks if this practice should continue or are there ways to improve the data collection process. Comments are due 60 days from the date of publication in the Federal Register.

U.S. federal agencies seek input on financial institution use of AI and machine learning. The Request for Information, published jointly by the Board of Governors of the Federal Reserve System, Bureau of Consumer Financial Protection, Federal Deposit Insurance Corporation, National Credit Union Administration, and Office of the Comptroller of the Currency, points out that financial institutions are exploring the use of AI to flag unusual transactions, personalize customer services, make credit decisions, manage risk, analyze text and conduct cybersecurity, among other uses.

The RFI points out the potential benefits and risks of using AI and requests input on potential barriers or challenges that data quality and data processing pose for developing, adopting, and managing AI. XBRL US intends to highlight the need for structured, consistent data in AI and machine learning applications, as the critical ingredient to ensure the integrity of AI outputs.

Are XBRL data better at predicting future stock returns? by Steven Huddart, Smeal College of Business, Penn State University. Research from Penn State finds that the flexibility, timeliness, granularity, and authoritative nature of freely available, as-filed XBRL data has advantages that sophisticated data users should consider. The research finds that while commercially available, normalized datasets serve an important role in the capital markets, as-filed (XBRL) data may have better predictive capabilities.
