Investigation or audit of a potential deal or investment opportunity
Due diligence is a process of verifying, investigating, or auditing a potential deal or investment opportunity to confirm all relevant facts and financial information, and to verify anything else that arises during an M&A or investment process. Due diligence is completed before a deal closes to provide the buyer with an assurance of what they’re getting.

Transactions that undergo due diligence are more likely to succeed. Due diligence contributes to making informed decisions by enhancing the quality of information available to decision-makers.
Due diligence allows the buyer to feel more comfortable that their expectations regarding the transaction are correct. In mergers and acquisitions (M&A), purchasing a business without doing due diligence substantially increases the risk to the purchaser.
Due diligence is conducted to instill trust in the purchaser. However, due diligence may also benefit the seller, as a rigorous financial examination may reveal that the fair market value of the seller’s company is higher than initially thought. Therefore, it is not uncommon for sellers to prepare due diligence reports themselves prior to potential transactions.
There are several reasons why due diligence is conducted:
The costs of a due diligence process depend on the scope and duration of the effort, which are heavily influenced by the complexity of the target company. Costs associated with due diligence are easily justifiable compared to the risks of failing to conduct it.
The parties to the deal determine who bears the expense of due diligence. Both the buyer and the seller typically pay for their own teams of investment bankers, accountants, attorneys, and other consultants.
There is an exhaustive list of possible due diligence questions to be addressed. Additional questions may be required for industry-specific M&A deals, while fewer questions may be required for smaller transactions. Below are typical due diligence questions addressed in an M&A transaction:
Understanding why the owners of the company are selling the business –
Examining historical financial statements and related financial metrics, with future projections
The quality of the company’s technology and intellectual property
How the company will fit into the buyer’s organization
The company’s target consumer base and the sales pipeline
The company’s management, employee base, and corporate structure
Pending, threatened, or settled litigation
Capacity, systems in place, outsourcing agreements, and recovery plan of the company’s IT
Review of organizational documents and corporate records
Environmental issues that the company faces and how they may affect the company
Review of the company’s production-related matters
Understanding the company’s marketing strategies and arrangements
Due diligence helps investors and companies understand the nature of a deal, the risks involved, and whether it fits their portfolio. Essentially, undergoing due diligence is like doing “homework” on a potential deal and is essential to informed investment decisions.
