Last Updated on July 8, 2024 by Kanakkupillai

Financial due diligence is an integral component of M&A transactions and is required of anyone wishing to sell their business without experiencing unpleasant surprises post-acquisition.

Buyers’ due diligence advisors will thoroughly analyse your financial statements to verify they reflect what was promised. Buyers will promptly change their offer if any fraudulent figures are used to increase valuations.

What is Due Diligence?

Due diligence is an essential concept in business and law. It refers to taking preventive actions that minimise risk. Security brokers, for instance, must disclose information about their securities before auctioning them; M&A deals, real estate purchases, business purchases or purchases of all kinds often use due diligence when discussing potential deals; it can even play an integral part in our everyday lives like selecting which credit card to use or choosing the restaurant for Saturday night dinner or weighing options when setting goals in life.

Financial due diligence (FDD) in mergers and acquisitions involves investigating a company’s finances and history before purchasing. This typically includes reviewing profitability, growth rates and customer churn rates; additionally, it’s wise to examine industry standards to measure how it stands up compared to similar businesses.

FDD serves to ensure that any company purchased is an ideal investment. This process entails checking whether there are sufficient cash reserves and whether they are not over-leveraged and evaluating any potential issues within operations, such as regulatory changes, labour laws, or economic risks such as a recession.

Finalising due diligence requires reviewing a company’s tax situation to ascertain if any back taxes are owed to them and what their projected tax bills should look like going forward. Due diligence generally lasts 45-60 days for individual buyers of mid-sized businesses, while it can take much longer for private equity groups and strategic investors. Buyers should take advantage of this essential step, and using an M&A tool can speed up this step to ensure everything is critical during due diligence.

What is FDD?

FDD (Financial Due Diligence) investigates a company’s financial statements, tax records, assets and liabilities, revenue streams and market position to ascertain if its finances are healthy and its business model sound. FDD typically involves professional firms performing this process but can also be conducted independently by buyers or investors.

Performing FDD is paramount to buyers and sellers, ensuring the financials are accurate and verifiable. For buyers, this helps prevent an unpleasant surprise that devalues a company and reduces the expected return on investment. Sellers use FDD to answer all inquiries from potential buyers about their finances while verifying all claims made against their company.

FDDs may vary in scope depending on the industry and size of their target business but generally involve conducting an in-depth investigation that covers everything from financial statements and order forecasts to market and industry information, interviews with key employees and even reviews of confidential documents in a secure virtual data room.

Utilising public web data when conducting your FDD can significantly enhance the accuracy and speed of this process. Public web data allows you to quickly identify any trends or anomalies in a company’s performance that might impede a deal and more about their customer or supplier relationships – this can be particularly useful when entering new markets or expanding overseas.

What are the Benefits of FDD?

  • Financial due diligence is critical to any business transaction, ensuring the numbers you work with are reliable and accurate. Doing this helps minimise surprises post-transaction and allows buyers to understand a company’s value better.
  • FDD can assist in identifying any potential issues with target companies before beginning the sale process, saving both parties time and money over time. For instance, significant historical or projected earnings volatility is often an indicator of potential problems later. Furthermore, FDD will uncover any hidden costs or legal or regulatory risks in any deal, potentially saving time and money.
  • FDD can also help assess whether target companies’ revenue generation trends are sustainable and identify any gaps or opportunities for growth within them.
  • If you are selling your business, the process of conducting FDD may feel like an audit; however, it’s essential to keep in mind that both parties involved in due diligence want the deal to close smoothly by remaining calm and cooperative during this phase of due diligence, it should all run more smoothly for everyone involved.
  • Prepare yourself for an exhaustive series of inquiries into your business finances, from revenues and profitability to cash flows and forecast accuracy. Depending on the nature of the audit, questions could include P&L information for the past five years and details regarding each subsidiary’s profitability. You will also need to show why any discrepancies exist within financial statements, providing a sufficient explanation.

What are the Risks of FDD?

  • The process of financial due diligence indicates a detailed assessment of the health state, which requests analyzing financial statements and tax records, assets and liabilities, channels of income earning, business model, place in the market, as well as other factors. As a critical component of any M&A deal, due diligence involves detailed research and evaluation.
  • It was crucial to work with an advisor for FDD because the results could lead to hidden issues that would tamper any deals, resulting in negative impacts. However, the indirect risks are minimized by revealing them during implementation processes and identifying strategies for overcoming such challenges.
  • FDD results may also have the ability to alter the price of any deal since buyers will see how comprehensively FDD has evaluated a company and have a clearer understanding of its worth; as a result, buyers may become less willing to purchase it altogether.
  • FDD can be time-consuming and laborious, requiring a comprehensive analysis of your company’s finances – often taking two months or longer. However, using an all-in-one application like SignalX, due diligence processes can be expedited significantly and reduce the duration by as much as 75%!
  • As a seller, you must complete a full FDD before selling your franchise. Doing this will give you all of the information necessary to sell at an equitable price and terms; moreover, an in-depth FDD may reveal issues that might cause buyers to leave a deal altogether. Furthermore, legal advice should be sought before finalising transactions to reduce risk and maximise return.

How to Conduct FDD?

  1. Financial due diligence (FDD) is an integral component of any M&A deal, verifying the company’s numbers match what has been advertised about their story, helping buyers derisk an acquisition and determining how they will earn a return on their investment. Conducting FDD can help prevent costly errors like overpaying for an acquisition.
  2. FDD processes typically begin by determining whether a company’s accounts are set up on either a cash or accrual basis, which is an essential question as it determines how the business records revenue and expenses, ultimately impacting how much money it has available for investment or financing purposes, along with revealing information such as financing method and debt load.
  3. After reviewing the company’s historical and forecast performance, all legal liabilities and capital expenditures should also be examined as part of this FDD process. Finally, public web data analysis helps uncover consumer sentiment analysis, assess competitors, and uncover growth opportunities.
  4. Buy-side financial due diligence (FDD) is usually conducted by private equity firms, venture capitalists, strategic investors, investment banks, family offices, sovereign wealth funds, pension funds and insurance companies. At the same time, individual investors or broker-dealers may also conduct sell-side FDD.
