The Sarbanes-Oxley Act (SOX) was passed in response to corporate accounting scandals to improve transparency and restore investor confidence. Sections 302 and 404 have significant implications for foreign private issuers (FPIs) listed on U.S. exchanges by requiring costly internal control systems and executive certifications. While SOX compliance has led some FPIs to delist or delay IPOs due to high costs, others see opportunities to attract investors through improved reporting. European countries are also strengthening governance rules, but in a way that considers differences from U.S. approaches and regulations. Over time, foreign companies may find U.S. markets beneficial if regulatory cooperation continues regarding corporate structure variations across countries.
