This chapter provides a detailed overview of the main types of corporate fraud, categorized into material misrepresentation, misappropriation of assets, and other fraudulent activities. Material misrepresentation encompasses financial statement fraud and greenwashing, both aiming to deceive stakeholders about a company's financial health or environmental responsibility. Misappropriation involves executives using company assets for personal benefit or to benefit third parties. Other fraudulent activities include misappropriation outside the corporate mandate and the abuse of the corporation for other fraudulent activities. The chapter emphasizes the importance of vigilance in detecting these corporate frauds through meticulous analysis of financial statements, public records, and media reports, as well as the use of advanced analytical tools and machine learning models.
