We investigate whether non-GAAP earnings disclosures increase stock price crash risk. Consistent with non-GAAP disclosures allowing managers to inflate investors’ perceptions about firm performance, our results indicate that income increasing non-GAAP reporting increases crash risk. We also find that managers can use non-GAAP reporting as a substitute for earnings management to withhold bad news from investors (the traditional explanation for crashes). Finally, we find a positive association between non-GAAP reporting and the likelihood of subsequent events that can trigger a crash. Overall, our evidence is consistent with some non-GAAP disclosures exposing investors to risks of large and sudden price declines.

ABSTRACT Regulation Fair Disclosure (Reg FD) Form 8‐K filings provide a venue where managers release information to the market as a whole that they designate as being material . Using this setting, we study trading patterns immediately prior to the public disclosure of material information. We offer three main results. First, using both intraday and daily trading data, we find abnormal trading volume of 21 percent (13 percent) in the hour (day) prior to the public disclosure, respectively. Second, we find that this pre‐disclosure abnormal trading volume is concentrated in firms that are smaller, have more growth opportunities, issue fewer voluntary disclosures, and have weaker external monitoring. Finally, we find that this pre‐disclosure volume is concentrated in subsamples in which the information relates to a firm's material contracts, a firm holds investor/analyst conferences, and there is insider trading activity in a firm's shares. Our results do not concentrate in a small number of firms or industries, and do not appear to be explained by the form through which managers first release the material information (e.g., Form 8‐K, press release, website posting, or social media). Our results are also robust to controlling for the firm's other filings and peer filings that occur around the disclosure. Overall, the trading patterns we document may show that, inconsistent with the spirit of Reg FD, a subset of investors trade on information managers deem material prior to its broad, public release.

ABSTRACT We examine the disclosure of non-GAAP earnings information in quarters containing transitory gains to investigate whether the primary motivation for these managers to disclose non-GAAP earnings is to inform or mislead. In this setting, non-GAAP earnings are more informative than GAAP earnings, even though they are lower than GAAP earnings. Thus, managers motivated to inform stakeholders about sustainable earnings will disclose non-GAAP earnings information excluding the gain, whereas managers motivated to report higher earnings will obscure the transitory nature of the gain by focusing on GAAP earnings. We find evidence that managers' disclosure choices vary widely across firms, and these choices affect investors' perceptions of core operating earnings. We then contrast how the same firm discloses non-GAAP earnings in the presence of transitory losses to provide additional evidence on the motives of individual firms' disclosures. We conclude that the most pervasive motivation to disclose non-GAAP earnings in the presence of transitory gains is to inform. An economically significant proportion of firms, however, appear opportunistic in that they only disclose non-GAAP earnings information when it increases investors' perceptions of core operating earnings. Our evidence is important because we speak to the influence that each motive has on the choice to disclose non-GAAP earnings and we provide evidence on the underlying motives behind specific firms' disclosures.

We use newly available GAAP forecasts to document that traditionally-identified GAAP forecast errors contain 37% measurement error. Correcting for this measurement error, we settle a long-standing debate regarding investor preference for GAAP versus non-GAAP earnings and provide strong evidence of a preference for non-GAAP earnings. We also revisit the use of non-GAAP exclusions to meet analysts’ forecasts when GAAP earnings fall short. Results indicate that 34% of these traditionally-identified meet-or-beat firms are misidentified due to measurement error, and this error masks evidence that firms more frequently exclude transitory rather than recurring expenses for meet-or-beat purposes.

ABSTRACT We use a novel data set to examine the across‐time consistency and across‐firm comparability of firms' non‐GAAP earnings disclosures. Given widespread concern about non‐GAAP reporting among regulators, standard setters, the investor community, and academics, our investigation provides timely evidence on how managers' deviations from their own non‐GAAP disclosure history, or the reporting of industry peers, affects how well earnings inform on firm performance. We begin by identifying firms that change their non‐GAAP earnings definition from one year to the next. These deviations are uncommon, but when managers change the items they exclude in calculating non‐GAAP earnings, the changes generally enhance the information in earnings about firms' core performance. We also examine whether non‐GAAP earnings are more comparable than GAAP earnings and find that firms' non‐GAAP adjustments result in greater earnings comparability. Finally, we examine instances in which firms deviate from common sector‐wide definitions of non‐GAAP earnings. We find that these deviations also result in earnings metrics that better represent firms' core operations. Overall, our results suggest that when managers vary their non‐GAAP calculations, either across time or across firms, the resulting non‐GAAP metrics generally enhance the information in earnings about firms' ongoing performance. Thus, our analysis helps mitigate concerns about why managers might vary their non‐GAAP reporting calculations.

ABSTRACT Researchers frequently proxy for managers’ non‐GAAP disclosures using performance metrics available through analyst forecast data providers (FDPs), such as I/B/E/S. The extent to which FDP‐provided earnings are a valid proxy for managers’ non‐GAAP reporting, however, has been debated extensively. We explore this important question by creating the first large‐sample data set of managers’ non‐GAAP earnings disclosures, which we directly compare to I/B/E/S data. Although we find a substantial overlap between the two data sets, we also find that they differ in systematic ways because I/B/E/S (1) excludes managers’ lower quality non‐GAAP numbers and (2) sometimes provides higher quality non‐GAAP measures that managers do not explicitly disclose. Our results indicate that using I/B/E/S to identify managers’ non‐GAAP disclosures significantly underestimates the aggressiveness of their reporting choices. We encourage researchers interested in managers’ non‐GAAP reporting to use our newly available data set of manager‐disclosed non‐GAAP metrics because it more accurately captures managers’ reporting choices.

ABSTRACT We test whether firms that exclude the effects of amortization from non-GAAP earnings allocate more of an acquisition’s purchase price to definite-lived intangible assets (DLIA). This strategy can yield two potential benefits: it can (1) increase non-GAAP earnings by shifting depreciation of tangible assets, which is often included in non-GAAP earnings, to amortization of DLIA, which non-GAAP earnings exclude, and (2) decrease the likelihood of future impairments by shifting allocations from goodwill to DLIA. Consistent with expectations, we find that non-GAAP-reporting firms that exclude amortization from non-GAAP earnings allocate more of the purchase price to DLIA. We also find that these firms allocate less of the purchase price to depreciable assets and goodwill. Finally, we document earnings surprise and valuation benefits related to these allocation choices. Overall, our results provide new evidence about non-GAAP reporting and purchase price allocations and suggest that non-GAAP reporting can influence management’s GAAP accounting choices.
