Comprehensive due diligence review or due diligence is carried out when a company is considering a potential purchase or the possibility of making a particular deal. Due diligence is aimed to verify and analyze a potential deal with the purpose of determining possible risks and benefits, as well as confirming all relevant facts and financial information. In the course of due diligence process, a significant amount of information is collected in all areas of business. Namely, due diligence requires an analysis of past and current results, confirmation of the accuracy of reports, an assessment of the viability of the deal (for example, M&A).

Purposeful counterparty due diligence is critical to effective research, assessment and the successful conclusion of sophisticated dealings, including international ones. At the moment, this issue is becoming more relevant than ever due to the growing atmosphere of uncertainty and new unpredictable threats to business. As the evidence from practice shows, the conduction of a comprehensive due diligence check when concluding deals is one of the necessary conditions for a positive result.

In the period of development of cyberspace, Fintech and other areas of business, which use advanced technologies, the legal assessment procedure is especially relevant, since it can also cover intellectual property items and other aspects.

Company Due Diligence check: What Do You Need to Know?

Although the due diligence procedure does not have one common system, usually there are two forms. So-called Anglo-Saxon methodology, which represents comprehensive legal and financial assessment, ensuring full disclosure of information before signing an agreement. The relevant documents detail the verification procedure, as well as the rights and obligations of the parties.

On the contrary to previous methodology, majority of countries in the world use preliminary finance and legal due diligence in a less strict order with limited disclosures. Already after the preliminary deal is concluded, a more rigorous common law due diligence process follows, which results in the conclusion of a basic agreement reflecting the business relationship.

Due Diligence process

Usually, the beginning of the due diligence process is characterized by an identification stage, in which key information is requested from a potential client or third party. Schematically the process is following:

  1. Identification.
  2. Examination.
  3. Risk assessment.

In order to conduct due diligence of a legal entity it is necessary to get from seller:

  • charter documents;
  • detailed information about founders and beneficiaries;
  • description of corporate structure;
  • information about the board of directors, etc.

At this stage, due diligence under English law may also require notarization of company documents.

Verification of a private entity usually requires the provision of:

  • identity confirmation;
  • data about the source of income and the origin of funds;
  • a description of possible political connections, depending on the intended type of activity.

Afterwards, company names, the names of private entities and the names of non-profit organizations will be verified by the global sanctions lists. At the same time, an additional due diligence check can be carried out with the lists of law enforcement agencies and regulators about known criminals, banned or disqualified companies and individuals.

Also, at this stage, lists of politically exposed persons (PEP) are checked to identify government or official relationships. This process is usually automated and processes thousands of records simultaneously. Based on the information obtained during the identification process and the results of the checks of the above lists, an assessment of the respective risks is carried out.
