Due Diligence in Mergers and Acquisitions
Executing a merger and acquisition requires meticulous planning and execution. Before closing a deal, buyers typically engage in specific, agreed-upon procedures to evaluate the target from commercial, financial, tax, and legal perspectives. Apart from addressing critical economic issues, this process encompasses a wide range of tax and regulatory matters, such as exchange control, indirect taxes, income taxes, and capital market regulations. This evaluation process is commonly referred to as a 'due diligence exercise'. It provides potential buyers with crucial information about the target business, helping them manage associated risks. This article delves into the concept of Due Diligence and its various aspects.
Types of Due Diligence
Due diligence can be categorized into different types based on who conducts the Due Diligence and what aspects are examined.
Primary Interest Perspective
From the fundamental perspective of 'who' conducts the Due Diligence, there are two main types:
- Buyer Due Diligence: Typically, Due Diligence refers to the examination conducted by the buyer or acquirer, who seeks insight into the target's potential upsides and risks. Buyers usually appoint consultants to carry out this process, providing expert advice on the findings.
- Vendor Due Diligence: Increasingly popular, vendor Due Diligence is conducted by the target entity's management. Consultants are hired to produce a report highlighting the target's exposures or benefits. This report is shared with potential investors or acquirers, helping them make investment decisions.
Functional Perspective
Regarding functional perspective, the focus is on what aspects of the target are being evaluated. In India, various types of Due Diligence are prevalent, including commercial, technical, environmental, human resource, and legal assessments.
Due Diligence vs. Statutory Audit & Internal Audit
In India, it is mandatory for companies to conduct statutory audits by independent Chartered Accountants and, in some cases, internal audits concerning their processes. While Due Diligence significantly differs from these audits, their comparison provides clarity:
| Parameter | Statutory Audit | Internal Audit | Due Diligence |
| Appointed by | Shareholders of the company | Management of the company | Generally by the buyer and sometimes by the management of the target |
| The reader of the report | Shareholders, regulatory authorities | Management | Deal-making parties |
| Extent of reliance on information provided by management | Relatively high | Relatively high | Low to medium; information is tested for reliability |
| Mandatory | Mandatorily required under the statute. | Mandatorily required under the statute for certain prescribed companies. | Not mandatory |
| Objective | To report on the fairness and truth of the financial statements. | To report on specific issues with the internal processes of the company. | To highlight exposures and upsides of the target. |
| Scope | Defined by nature | Defined by the management | No specific scope; determined by the buyer or seller |
| Perspective and focus | Focuses on past information | Adopts a futuristic approach | Blends past and futuristic perspectives |
| Confidentiality | Low; for listed companies, the audit report is publicly accessible. | High; typically, only management has access to the report. | High; only the deal-making parties have access to the report. |
Due Diligence from a Tax Perspective
Tax is an unavoidable and substantial cost, making tax Due Diligence a significant element in M&A decision making. Although tax is not the primary concern in M&A transactions, understanding the target's tax profile and quantifying tax exposures can reveal crucial insights. Tax Due Diligence also uncovers potential tax benefits accessible to the target, helping in structuring the deal efficiently.
While conducting tax Due Diligence, buyers must identify potential tax risks and ensure adequate protection, often through tax warranties and indemnities. This helps balance the negotiations and does not impact the transaction's commercial feasibility for the seller.
In summary, tax Due Diligence aims to:
- Validate tax representations made during pre-deal negotiations.
- Confirm tax assumptions used to value the target.
- Identify material tax exposures and their characteristics.
- Identify potential tax benefits being claimed by the target.
- Structure the deal to optimize tax efficiency.
- Assess the availability of tax losses, credits, and other tax assets.
- Implement adequate protection mechanisms, such as warranties and indemnities.
