1. Overview of Global M&A Regulatory Frameworks

Mergers and Acquisitions (M&A) involve the combination or transfer of ownership of companies. Global M&A regulatory frameworks are designed to ensure that such transactions comply with antitrust, securities, foreign investment, labor, and tax laws across jurisdictions.

Key Objectives:

Antitrust & Competition Compliance: Prevent anti-competitive market concentration.
Foreign Investment Control: Ensure national security and strategic interests are protected.
Securities & Shareholder Protection: Ensure transparency, disclosure, and fairness to shareholders.
Labor & Employment Considerations: Safeguard employee rights and benefits post-transaction.
Tax & Accounting Compliance: Proper reporting and avoidance of illicit tax avoidance or evasion.

Global Frameworks and Authorities:

United States: Hart-Scott-Rodino (HSR) Act, DOJ & FTC antitrust review, SEC disclosure rules.
European Union: EU Merger Regulation (EUMR), European Commission antitrust oversight.
United Kingdom: Competition and Markets Authority (CMA), Takeover Code.
China: Ministry of Commerce (MOFCOM) and Anti-Monopoly Law.
India: Competition Commission of India (CCI), Securities and Exchange Board of India (SEBI).
