Due diligence in M&A – full scope, red flag, or limited scope? Classification based on the scope of the examination

Due diligence (DD) is one of the key stages of an M&A transaction, an investor's entry into a company, restructuring, or preparation for the sale of a business. Its purpose is to identify legal, financial, and tax risks that may affect the value of the company, the structure of the transaction, and the scope of liability of the parties. 

In practice, the examination includes, among other things, an analysis of corporate documents, commercial contracts, disputes, financial obligations, tax settlements, and regulatory issues. However, not every transaction requires the same broad approach. Depending on the scale of the project, time, budget, and level of acceptable risk, the scope of due diligence may vary.

Below is a basic breakdown based on the scope and depth of the review.

Full scope due diligence

Full scope due diligence is the most comprehensive review model. It includes a comprehensive analysis of all relevant areas of the company's operations, in particular legal, financial, and tax matters.

The examination is in-depth and systematic. Not only potential irregularities are analyzed, but also the corporate structure, ownership relations, decision-making mechanisms, key contracts, collateral, financing, compliance, and regulatory risks. It is often accompanied by a detailed report identifying the risks and assessing their impact on the transaction.

This model is used in high-value transactions, majority acquisitions, and situations where the investor has no prior knowledge of the company. It provides the highest level of security but is more costly and time-consuming.

Red flag due diligence

Red flag due diligence focuses exclusively on identifying the most significant risks that may affect the investment decision or the terms of the transaction.

Instead of a detailed analysis of all documentation, the review focuses on sensitive areas: disputes, restrictions on the transferability of shares, key agreements, significant liabilities, regulatory risks, and potential tax irregularities. The report is usually more synthetic in nature and primarily identifies risks that require a response.

This model works well in competitive processes, when there is limited time for analysis, or in smaller-scale transactions. It allows for quick decision-making, but does not provide as complete a picture as a full scope review.

Limited scope due diligence

Limited scope due diligence involves narrowing the analysis to specific areas. The scope of the review is determined in advance and responds to the specific needs of the investor.

For example, it may be exclusively a corporate review (share ownership, correctness of resolutions), exclusively a tax review, or limited to a specific segment of the business. This model is sometimes used when the investor is already a partner in the company and has partial knowledge of its operations, or when the transaction concerns a separate part of the business.

The scope of the investigation as part of the transaction strategy

The choice between full scope, red flag, and limited scope is not solely a technical decision. It is part of the negotiation and risk management strategy. A broader investigation increases security but may prolong the process and increase costs. A limited investigation speeds up the transaction but leaves a greater degree of uncertainty.

In the next article, we discuss another criterion for dividing due diligence – based on the entity initiating and organizing the examination. This distinction is equally important for the dynamics of the transaction and the distribution of risks between the parties.
