Abstract

fetched live from OpenAlex

In light of rising cybersecurity concerns, companies are increasingly focusing on risk management and data security. This study explores the disclosure of cybersecurity incidents as a proxy for changes in financial reporting tone. Specifically, I expect a change in tone around the publication of the annual and quarterly reports of U.S. S&P 500 healthcare and medical providers industry (MED) companies during the 2010 to 2019 time period. Building upon existing literature on narrative accounting tone and data security breaches (DSBs) and further complemented by literature on board characteristics, earnings quality, and financial performance, this research aims to fill a gap by analyzing how narrative tone shifts following DSBs. Using a quantitative approach, this study conducts a quarterly analysis of the SEC’s 10-Q and 10-K reports to assess how narrative tone shifts in the quarters preceding a DSB announcement and in the quarter a DSB is disclosed and announced. The findings underscore a noticeable impact of DSB disclosures on narrative tone. This study contributes to the existing literature by highlighting the importance of the analysis of narrative tone as a tool in risk evaluation and has implications for auditors, analysts and stakeholders of interest.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
