The Financial Conduct Authority (FCA) is the financial regulator in the United Kingdom, but operates independently of the United Kingdom government and is funded by levying fees from participants in the financial services industry. The FCA regulates consumer financial services firms and maintains the integrity of financial markets in the United Kingdom. It focuses on regulating the behavior of both retail and wholesale financial services companies. Like its predecessor FSA, FCA is structured as a limited liability company. The FCA works with the Prudential Regulatory Authority and the Financial Policy Committee to establish regulatory requirements for the financial sector. The FCA is responsible for running about 58,000 businesses that employ 2.2 million people and contribute approximately £ 65.6 billion in annual tax revenue to the UK economy.

Companies House of the United Kingdom is the Registrar of Companies and the Executing Agency and Trade Fund of Her Majesty's Government. He falls under the purview of the Department of Business, Energy and Industrial Strategy (BEIS) and is also a member of the Public Data group. All forms of companies (as permitted by the Companies Act of the United Kingdom) are incorporated and registered with Companies House and present specific data as required by the current Companies Act 2006. All registered limited liability companies, including subsidiaries, small and dormant companies, must file annual financial statements in addition to the company's annual statements, which are publicly available. Only certain registered companies with unlimited members (meeting certain conditions) are exempt from this requirement.

The Securities and Exchange Commission (SEC) is the main regulator of the American stock market, which sets the rules for registering securities, as well as oversees the activities of stock exchanges. Created in 1933, the Securities and Exchange Commission was intended to restore investor confidence in the stock market, which had been severely shaken during the Great Depression. Today, the Commission is responsible for enforcing laws on securities and exchanges.

The Legal Entity Identification (LEI) code is a 20-character alphanumeric code that is based on the ISO 17442 standard developed by the International Organization for Standardization (ISO). It is created on the basis of reference information, which provides the ability to clearly and uniquely identify legal entities involved in financial transactions. Each LEI contains information about the ownership structure of legal entities and thus provides answers to the questions of “who is who” and “who owns whom”. In simple terms, this publicly available LEI database can be considered an international reference that significantly increases transparency in the global marketplace.
