Eight othersmostly based in Europe, and including Allianz, Amundi, BNP Paribas, DWS, and Schrodersencourage the ISSB to consider a double materiality approach, incorporating companies' impacts on the environment and wider society, in line with the European Commission's proposals. ESRS 2 General disclosures providing DRs on general reporting issues, governance, strategy and business model and the double materiality assessment process of sustainability impacts, risks and opportunities. This publication is distributed with the understanding that the author, publisher and distributor of this publication and/or any linked publication are not rendering legal, accounting, or other professional advice or opinions on specific facts or matters and, accordingly, assume no liability whatsoever in connection with its use. Far from it, assured the ISSBs vice-chair, Sue Lloyd, during the ISSBs 21 September meeting: [F]or those listening, I think we need to be careful to be very clear that this isnt because we are not worrying about the comments that we received and the feedback that weve got. In the context of ESG, this is known as single materiality and means mainly environmental, social and governance factors that may pose a threat or opportunity to a business and its bottom line. These are the risks to the social and environmental systems in which the economy is embedded. In their 2021 book, Moving beyond Modern Portfolio Theory: Investing that Matters, Jon Lukomnik and James Hawley explained that these systematic risks inevitably swamp any alpha strategy: It is not that alpha does not matter to an investor (although investors only want positive alpha, which is impossible on a total market basis), but that the impact of the market return driven by systematic risk swamps virtually any possible scenario created by skillful analysis or trading or portfolio construction. The increasing recognition of the importance of beta to investors could make a beta-free ISSB standard obsolete from the start. E/S information that does not affect investors, but is relevant to the impact companies have on civil society and stakeholders other than investors (stakeholder data). The growing importance of this field is evident in the creation of the International Sustainability Standards Board (the ISSB) to establish uniform E/S disclosure standards that companies around the world will use to report to investors. The net result for the [diversified] investor can be negative when the costs across the rest of the portfolio (or market/economy) outweigh the gains to the company; A company or sector securing regulation that favours its interests over others. . For example, an investor might conclude that a company can avoid reputational, regulatory, and supply chain risks by adopting better labor and energy practices. The expectation is that this cost will be outweighed by the benefits to the market and companies of having more complete, transparent, comparable and reliable information on which to base resource allocation decisions. The actual influence of certain behaviours on cash flows are still being understood and standard models for measurement in these areas are nascent, or missing altogether. The return to such diversified investors chiefly depends upon beta, not the performance of individual companies. As noted above, the GRIs disclosure standards adopt a broad, multi-stakeholder interpretation of materiality. The ISSB documentation expressly rejects "double materiality," the standard European regulators embrace, which couples financial materiality with information designed to inform other stakeholder data. See Andrew Howard, SustainEx: Examining the Social Value of Corporate Activities (Schroders 2019). Related research from the Program on Corporate Governance includes Companies Should Maximize Shareholder Welfare Not Market Value by Oliver Hart and Luigi Zingales (discussed on the Forum here); Reconciling Fiduciary Duty and Social Conscience: The Law and Economics of ESG Investing by a Trustee by Max M. Schanzenbach and Robert H. Sitkoff (discussed on the Forum here); and Exit vs. Voice by Eleonora Broccardo, Oliver Hart and Luigi Zingales (discussed on the Forum here). Given the ISSBs potential to influence voluntary and mandatory sustainability reporting expectations, companies may wish to consider using its standards to help inform their sustainability disclosure strategy. Taking a market view adds an element of objectivity to the materiality assessment. In such cases, E/S impact and financial return are integrated, as are disclosures with respect to each. What has the Net Zero Asset Owner Alliance actually said about carbon offsets? But as capital markets matured, investors began to contemplate a more active role, and after a divestment campaign helped end South African apartheid, the idea that investors could change bad corporate behavior, rather than simply avoiding it, developed a broader following. This view of materiality doesnt ask the company to have a crystal ball, only to think about likely future risks or events such as resource shortages or environmental damage that could change the way they structure their business model and, ultimately, do business. The UK government has gone a step further, signaling it intends to adopt the ISSBs standards as part of future mandatory sustainability reporting requirements under the Sustainability Disclosure Regulation (SDR).2. IFRS Advisory Council questions ISSB on future of SASB standards. The Technical Readiness Working Group (the TRWG) recently released a set of recommendations for general requirements for the ISSB standards (the General Requirements) that addressed this question by defining what would be material for the standards overall. For purely financial information, the standard must elicit the financial metrics and qualitative descriptions that investors use to model value. A consultation paper on the SDR is expected in the second quarter of 2022.. The market must find a way to determine when this is important, and crucially, when it is not. But from a disclosure perspective, investors should have the data that would allow them to understand the risk the company is taking by continuing to externalize costs. All rights reserved. E/S information that involves the residue of E/S impacts that do not affect investment returns, but that impact on other matters that are important to individual investors (non-financial investor impacts). Interest 61 (1971). If the company were degrading the environment by causing drought with over-extraction then clearly EFRAGs materiality definition would require this outward impact to be reported. The General Requirements Standard recommends that companies disclose material sustainability-related information, defined as information that could reasonably be expected to influence primary users assessments of an entitys enterprise value, with the responsibility for the materiality assessment resting on the reporting entity. The International Sustainability Standards Board (ISSB) is analysing feedback to its consultation on two proposed standards and will consider how to respond to stakeholder comments on topics such as enterprise value and materiality, the head of the IFRS Foundation said. Dana Peterson and Catherine Mann, Closing the Racial Inequality Gaps: The Economic Cost of Black Inequality in the U.S. (2020). As such, we urge you to rethink your whole approach to this issue. But investors wont give companies a free pass and their patience will wear thin quickly if companies do not appear to take this reporting seriously. This means that companies have to report on both the financial and environmental implications of their sustainability efforts. The failure to even address beta-oriented disclosure is surprising because there is a growing emphasis on the need for diversified investors to monitor and steward the beta impact of portfolio company activity. But double materiality adds inside-out information, namely, information relevant to the companys impacts on society and the environment. Adding beta information to the ISSB reporting standard would not significantly enlarge the reporting requirement because any company conduct that threatens or benefits beta is likely to create corresponding regulatory and reputational risks and benefits to enterprise value, so that most beta information should be deemed material even under a putative ESG standard. This then helps create the business case for companies to take action on the priorities that their investors, customers and others really care about. Materiality: The First Step in ESG Management The easiest way to think of materiality is as a relevancy filter for the issues that matter most to an organization. Although the ISSB does not provide specific guidance on where such disclosures must be made relative to general purpose financial reports, it emphasizes that sustainability-related information should be disclosed simultaneously with standard financial information and in as integrated a manner as possible. In practice, this shifts the focus to the forward-looking or anticipatory aspects of double materiality. We must focus on what unites us in agreement and we cannot afford for minor differences to get in the way of progress. It defines a liability as a present obligation of the entity arising from past events, the settlement of which is expected to result in an outflow from the entity of resources embodying economic benefits. See Thomas C. Schelling, On the Ecology of Micromotives, 25 Pub. It explains the approaches of the GRI Standards ( impact materiality), the IFRS' International Sustainability Standards Board (ISSB) ( financial materiality) and the incoming European Sustainability Reporting Standards ( double materiality), and how they interconnect. In what follows, we'll break down the concepts of "materiality" and "double materiality" and share some key takeaways about their importance to ESG management. Influential investors such as BlackRock have previously encouraged companies to voluntarily disclose in line with both TCFD and SASB, and companies that have already developed such procedures for sustainability reporting will find it easier to adapt to the ISSBs framework. In Europe, double materiality - reporting on both sustainability factors affecting the company (financial materiality) and how the company impacts on society and the environment (outward materiality) - is already part of the European Commission's proposed Corporate Sustainability Reporting Directive (CSRD). This is a critically important public policy development, not simply because it will improve investment returns, but because it will lead to better social and environmental outcomes on the ground, as many of the most serious threats to beta are also the most serious threats to people and the planet on which we live. They threaten the functioning of the economic, financial and wider systems on which investment performance relies. If companies increase their own bottom line by emitting extra carbon, by refusing to share technology that will slow the pandemic, or by contributing to inequality, the financial benefits earned for their individual companies may be dwarfed by comparison to the costs the economy bears. For ESG integration, the standard must call for disclosures of E/S matters that investors can use to model an enterprises value and future cash flows. Please see www.pwc.com/structure for further details. Sustainable investing. This does not mean that disclosure standards drafters do not themselves need to understand the contextthat understanding is critical to eliciting the correct information for investors to use. Continue the context-setting projects for beta-level impacts of E/S issues outside the ISSB process. At a time when regulation alone seems increasingly inadequate to the task of addressing threats to the environment and our social fabric, an apparent retreat from a constructive market reform in a document as influential as the ISSB standards would be a serious setback. Sustainability materiality must be accepted as ever evolving, as it is for financial statement materiality. As Hales explained: "Dual materiality and dynamic materiality are not new concepts, it's just that there's new language and an evolving understanding of these issues [that] helps to bring some clarity to frankly a concept that has been very challenging to communicate about for a long time." One key element of materiality is its specificity. The version of enterprise value we use in financial reporting today would consider the effect of many sustainability matters on long-term cash flows as hardly material since they are inherently uncertain and typically have little effect on the business today. Planetary forces much greater than cataclysmic weather events have decided that. Encourage the ISSB drafters to move to an express sesquimateriality standard. It suggests that corporate activity that threatens critical systems is not material if that activity does not threaten enterprise value at the company in question. union of two sets, not intersection) of impact materiality Thinking about the water usage example above, its clear that a company would end up reporting much the same information under the ISSBs and SECs proposals as they would under EFRAGs. Environmental, social and governance (ESG) integration. As discussed in the Freshfields Report and the PRI Report, decision-useful information extends beyond information that affects enterprise value; if a companys E/S impact has the potential to affect beta, diversified shareholders may well act on that information by, for example, voting against directors who fail to act to mitigate negative externalities. Before discussing the ISSB and the desirability of a sesquimateriality standard, we review several elements of E/S investing. The double-materiality concept as 'guiding principle' in the GRI Standards From climate change and biodiversity loss, to growing inequality, modern slavery, and scarcity of resources, our society and planet face the most significant challenges of all times. But it does not tell shareholders how to use this data to value securities: the user provides that context. Because negative externalities burden the economy and beta. This article addresses a fundamental debate over the purpose of the uniform standard and reaches the following conclusions: Four types of impact. Yet diversified portfolios remain exposed to nondiversifiable risks, for example where declining environmental or social sustainability undermines the performance of whole markets or sectors Indeed, for investors who are likely to hold diversified portfolios in the long-term, the question is particularly pressing since these are likely to be the main ways in which they may be able to make a difference. First, this is a rapidly evolving area and both science and social mores will mean that the items material to a business will constantly be shifting and changing. The US Securities and Exchange Commission is also beavering away on its own climate-reporting proposals. More immediately, the difference between an efficient response to COVID-19 and an inefficient one could create a $9 trillion swing in GDP. Companies are advised to monitor the continued development of the exposure drafts and may wish to consider aligning future sustainability reporting with key components of the General Requirements Standard, including relying on company- and industry-appropriate standards such as those of SASB. It recently issued a report (the PRI Report) that described a variety of corporate practices that can boost individual company returns while threatening the economy and diversified investor returns: A company strengthening its position by externalising costs onto others. For an overview of the SECs proposed climate rule and its implications, please refer to our March 24 Alert., 2. And, on the surface, this could threaten progress towards global alignment. This divergence of interests arises in many cases from the unpriced availability of finite common resources, such as the earths carbon sink or the capacity of society to absorb growing inequality. The ISSB will accept feedback on its General Requirements and Climate Standards until July 29, 2022, and will incorporate the comments it receives into its final sustainability reporting standards, expected by the end of 2022. Although there is no charge to the income statement, the reduction in shareholder equity arising from this proposal would reduce the amount of distributable reserve available to shareholders. The task of building a sustainable future is a shared responsibility for us all. The materiality principle chosen in the General Requirements seems to ignore the most important issue on the table without explanation. Global Leader, Public Policy & Regulation, PwC United Kingdom, Director of Investor Engagement, PwC United Kingdom. Similarly, they might be willing to sacrifice portfolio return if it meant a healthier environment in which to enjoy their retirement, or if doing so would relieve others suffering. The Statement of Intent to Work Together Towards Comprehensive Corporate Reporting co-authored by five important standard setting organizations, was a 2020 document that was an important step towards the ISSB process; it describes inside-out information as being targeted at: various users with various objectives who want to understand the enterprises positive and negative contributions to sustainable development [in contrast to enterprise value information targeted] [s]pecifically to the sub-set of those users whose primary objective is to improve economic decisions. The ISSB drafters should recognize the risk that excluding beta could, at the margins, lead to the omission of decision-critical information for investors concerned with company impact on social and environmental systems that support other portfolio companies. Disagreement over definitions is just one element of the materiality issue. This means stewardship that is less focused on the risks and returns of individual holdings, and more on addressing systemic or beta issues such as climate change and corruption. Furthermore, the ISSB recommends that entities rely on industry-specific guidance for certain disclosures in addition to industry-agnostic general reporting guidance. ISSBs Proposed Framework Seeks to Unify Global Sustainability Disclosure Standards, Private Equity International Responsible Investment Forum, Kirkland Advises Greenbriar Equity Group on $3.475 Billion Fundraise for Oversubscribed Sixth Fund, Kirkland Advises Patient Square Capital on Record $3.9 Billion Inaugural Fundraise, General Requirements for Disclosure of Sustainability-Related Financial Information, European Sustainability Reporting Standards. The application of 'double materiality' has always been a central theme for GRI since its inception, largely due to the fact that its development is based on a multi-stakeholder approach, in which trade unions and civil society groups hold significant influence. It is unclear why the General Requirements present double materiality and ESG as the only choices. Double vs single vs dynamic materiality is one of the main pieces of contention between the ISSB and EFRAG in the design of their sustainability standards but what if this was only theoretical and in practice their thinking aligns? The current plan for the ISSB expressly encompasses only data that implicate enterprise value (often called financial materiality), although a close read of the documentation produced to date leaves the door open for an expansion to information pertinent to beta information as well. outside-in materiality - or ESG reporting as it is most commonly adopted today), to also disclose the impact of those same companies on society and the environment (i.e . The ISSB documentation expressly rejects double materiality, the standard European regulators embrace, which couples financial materiality with information designed to inform other stakeholder data. Shortly after the International Sustainability Standards Board (ISSB) tentatively confirmed that companies using its climate-reporting standard must disclose their Scope 3 greenhouse gas (GHG) emissions, board chair Emmanuel Faber took to Twitter, making the bold claim that the board was rewriting economics. This is known as the single-materiality approach, as opposed to a double-materiality approach that considers impact both ways. These will include information that allows investors to draw conclusions as to whether the companys reputation is at risk, or whether it may be subject to regulation or increased costs when regulation is adopted to address currently unmitigated social or environmental costs. Tony Moller provided valuable research and drafting assistance in support of this Alert. While there are some obvious areas of agreement across the three sustainability reporting proposals including their overall objectives to provide information about a companys strategy, risks and targets for dealing with sustainability matters, and the need to look out over the short-, medium-, and long-term time horizons there is also deep division. Finally, from a rhetorical perspective, it is important that the final documentation of the ISSB standards acknowledge that investors have significant interests in beta impacts. Below, we highlight three key takeaways from the draft General Requirements and Climate Standards. Despite all the talk of urgency from IOSCO, the climate-change standard will not be in place until next year. Furthermore, the Global Reporting Initiative (GRI) which provides standards for companies to disclose their environmental and social impacts to a broader set of stakeholders than investors and is the most widely used disclosure system globally has pledged to coordinate its future standard-setting activities with those of the ISSB to provide two pillars of international sustainability reporting. Firstly, the time element will force companies reporting under either the ISSBs and SECs rules to include outward impacts since, logically, the outward impact will eventually work its way inward. Lastly, the fact that many companies will have to report new information and in large quantities could have the potential to cause a period of significant volatility in markets. Not all investors are diversified, so if a company protects beta by accepting reduced enterprise value, it may be favoring diversified investors at the expense of concentrated investors. At a time when regulation alone seems increasingly inadequate to the task of addressing threats to the environment and our social fabric, an apparent retreat from a market-based solution in a document as influential as the ISSB standards would be a serious setback. Diversified investors internalize the collective costs of such externalities (more than $2 trillion in 2018 according to the Schroders report cited above) because they degrade the systems upon which economic growth and corporate financial returns depend. This convergence is illustrated in Figure 1 below. This is a critical moment. Indeed, Institutional Shareholder Services, the worlds leading proxy adviser, recently announced it would do exactly that in its benchmark recommendation policy, treating a companys climate damage to the economy in parallel with damage to the enterprise. The last category of information is that which is relevant to stakeholders other than shareholders. As one work describes this, [a]ccording to widely accepted research, alpha [over- or under-performance of individual securities] is about one-tenth as important as beta [and] drives some 91 percent of the average portfolios return.
