Intangible Liabilities: The Hidden Risks That Shape Firm Value

Arnt Verriest , KU Leuven

In this article, Hamid Boustanifar (EDHEC) and Arnt Verriest (KU Leuven) present their latest research, published in Management Science (1). They’ve developed and analysed the concept of “intangible liabilities” which stem from legal, regulatory, and reputational risks, liabilities that are a significant determinant of firm value and stock returns.

Companies have intangible assets (2): economically important resources such as brands, know-how, or human capital that do not appear on the balance sheet. But they can also have economically important obligations that do not appear on the balance sheet. These obligations are not recognised as accounting liabilities because they are uncertain or difficult for management to estimate reliably. We call them intangible liabilities.

Intangible liabilities can arise from lawsuits, product liability claims, environmental matters, patent or copyright disputes, false advertising, regulatory investigations, and other legal or reputational risks. A notable example is 3M, which had not recorded any accounting reserve for major earplug litigation risks at the time, even as investors worried that these issues could impose billions of dollars in future costs (3). In its filings, 3M stated that it had not recorded any reserve because the liability was not probable and the potential costs could not be reasonably estimated.

 

Such cases may not show up as numbers on the balance sheet, but public companies must still disclose important risks and contingencies in their annual reports. We use this disclosure text to construct a firm-level, text-based measure of intangible liabilities (1).

We analyse the annual reports of U.S.-listed firms (4) since the mid-1990s when electronic filings became mandatory. We build an intangible liabilities dictionary containing 569 words and phrases related to potential obligations, including “class action,” “product liability,” “environmental liability,” “infringement,” and “settlement.” We then use the frequency of these terms to measure intangible liabilities for more than 112,000 firm-year observations. 

Our premise is simple, transparent, and yet very informative: companies with higher intangible liabilities will have higher frequencies of these related terms in their disclosures. 

The measure behaves in intuitive ways. It is higher in industries such as tobacco, insurance, healthcare, pharmaceuticals, and utilities, but there is also substantial variation among firms within the same industry. Importantly, intangible liabilities predict real future outcomes. Firms with higher measured exposure are more likely to face future class action lawsuits and reputational damage, as reflected in negative media coverage. They also face a higher probability of future stock price crashes.

The stock market appears to price these risks. Companies with greater intangible liabilities trade at lower valuation ratios, and investors demand higher expected returns to hold their stocks. A portfolio that buys stocks with high intangible liabilities and sells stocks with low intangible liabilities earns about 3% per year in abnormal returns after accounting for common risk factors and industry effects.

 

The main implication is simple: some of the most important risks and liabilities companies face are not visible in accounting numbers. They are often hidden in the text of corporate disclosures. Reading and measuring that text can help investors, managers, auditors, regulators, and other stakeholders better understand the legal, reputational, and financial risks that may shape a firm’s future value.

 

We view our work on Intangible Liabilities as a first step toward drawing attention to these hidden obligations, which may affect important corporate decisions, including financing, acquisitions, compensation, and risk management.
