Purpose of Due Diligence

  • Due diligence is the reasonable investigation performed to verify material information, identify risks, support disclosure, and inform valuation and negotiations. In underwriting, it helps establish a due diligence defense and reduce the risk of material misstatements or omissions.
  • In M&A, due diligence supports the buyer's understanding of financial, legal, tax, operational, commercial, environmental, cybersecurity, and compliance issues before signing or closing.

Process

  • The process typically involves a request list, data room review, management Q&A, expert workstreams, site visits, customer and vendor analysis where permitted, and iterative issue tracking. Bankers coordinate specialists and help determine which issues are value-affecting, indemnifiable, or deal-breaking.
  • Findings can change price, structure, financing terms, covenants, closing conditions, indemnities, escrows, or the decision to proceed at all.

Types of Review

  • Financial diligence focuses on quality of earnings, debt-like items, working capital normalization, and cash conversion.
  • Legal diligence reviews contracts, litigation, permits, intellectual property, organizational documents, and compliance. Tax diligence addresses exposures, structure, and post-closing consequences.

Series 79 focus

  • Understand why diligence is continuous rather than a one-time checklist, how red flags affect negotiation leverage, and why diligence is central both to underwriting liability management and advisory quality. Exam questions may test which issues are material, who performs diligence, and how discoveries influence transaction terms.

Key facts to memorize

  • Due diligence supports disclosure accuracy and risk identification
  • Common tracks include financial, legal, tax, operational, and compliance diligence
  • Quality of earnings and working capital review are major financial diligence areas
  • Findings can affect valuation, indemnities, covenants, and closing conditions
  • Diligence is important in both securities offerings and M&A transactions

Mnemonics that stick

  • "Diligence detects disclosure danger"
  • "QofE, legal, tax, ops" for core diligence tracks
  • "Findings change price, paper, or proceed decision"

Exam traps

  • Due diligence is not limited to financial statements; legal, operational, regulatory, and tax issues can be equally material
  • A clean management presentation does not replace independent diligence
  • Red flags found late in the process can still alter structure or price materially
  • Underwriters cannot rely blindly on issuer management if contradictory facts are available
