The study sample consists of 19 companies continuously included in the BIST Corporate Governance Index in the 2012-2021 period and whose data can be accessed. The determination of whether there is financial manipulation in a company was determined by the Beneish (1999) model; experience, seniority, duality, gender, nationality, and experience variables were used to represent the characteristics of CEOs. The panel logit model was run. According to the findings, CEO duality in companies acting in line with corporate governance principles increases the probability of financial information manipulation by 15%.eninfo:eu-repo/semantics/openAccessCEO Characteristics; Financial Information Manipulation; Panel Logit Model; Beneish Model; M-Score; BIST Corporate Governance IndexArticle1021187121610.30798/makuiibf.1219646WOS:001045333700015Q4
