Doing Your Due Diligence

Due diligence has been used since at least the mid-fifteenth century in the literal sense “requisite effort.” Centuries later, the phrase developed a legal meaning, namely, “the care that a reasonable person takes to avoid harm to other persons or their property”; in this sense, it is synonymous with another legal term, ordinary care. More recently, due diligence has extended its reach into business contexts, signifying the research a company performs before engaging in a financial transaction. This meaning may also apply to individuals: people are often advised to perform their due diligence before buying a house, signing a loan, or making any important purchase.

Financial Definition of due diligence

What It Is

Due diligence is the careful, thorough evaluation of a potential investment, whether on a corporate or individual level.

How It Works

For individual investors, due diligence often means studying annual reports, SEC filings, and any other relevant information about a company and its securities. The objective is to verify the material facts related to the purchase of the investment, as well as to understand whether the investment fits an individuals return requirements, risk tolerance, income needs, and asset allocation goals.

An individual's due diligence might include reading the company’s last two or three annual reports, several recent 10-Qs, and any independent research they could find. In doing so, they would develop a sense of where Company XYZ is headed, what market factors might affect the stock’s price, and how volatile the stock is. This in turn might give them guidance about whether the investment is right for you, and if so, the size and timing of their investment.

In a merger scenario, due diligence often involves a team of people specially tasked with reviewing and verifying every aspect of an investment in another company. In many cases, this team might include lawyers, accountants, and investment bankers.

Why It Matters

Due diligence helps people and companies understand the nature of an investment, the risks of an investment, and how (or whether) an investment fits into a particular portfolio. Due diligence isn’t just good sense, it’s a duty investors owe to themselves -- doing this sort of "homework" on a potential investment is often essential to making prudent investment decisions.
