Due Diligence Activities

This unit's checklist: the disclosure standard, the reasonable-investigation defense, sell-side versus buy-side work, and the Sarbanes-Oxley checkpoints.

Which One-Liners Win Points?

• The disclosure standard has two prongs, both trigger liability: an untrue statement of material fact, OR omission of a material fact needed to keep the statements made not misleading. The "or" is the trap.
• A registration statement can be technically accurate sentence-by-sentence and still trigger liability if it leaves out a material fact a reasonable investor would want.
• The standard applies to public offering registration statements. Private offering memoranda (offering circulars, PPMs) are not covered merely for being offering documents; they're governed by antifraud and other provisions instead.
• Due diligence is the underwriter's defense, not a formality: non-issuer defendants (underwriters, outside directors, experts) assert a reasonable-investigation defense with reasonable grounds for belief.
• Bring-down due diligence is a pre-closing refresh confirming the record stays accurate up to the closing date, not a one-time signing event.
• Reverse due diligence is sell-side only: the seller's banker investigates the BUYERS' ability and willingness to close.
• Background checks are buy-side only, performed on TARGET leadership.
• Cost-saving identification is buy-side only: it is the buyer's synergy case for paying a premium.
• Off-balance-sheet items and unfunded pension or retiree-health liabilities are explicit buy-side risk-discovery targets because they hide from a quick balance-sheet read.

Which Numbers Matter Most?

Which Gotchas Trip Students Up?

• The reasonable-investigation framework gives NO fixed checklist. Reasonableness is situation-specific: type of issuer, type of security, type of person (office held, if an officer; other issuer relationship, if a director), reliance on knowledgeable personnel, and, for underwriters, the underwriting arrangement and information availability.
• An initial public offering (IPO) for a first-time issuer demands deeper investigation than a follow-on for a seasoned, well-covered public reporter. Issuer profile drives depth.
• Reasonable reliance on issuer officers, employees, and experts is an explicit factor, but reliance has limits: a banker who knows or should know a relied-upon statement is suspect cannot hide behind reliance.
• The Form 4 deadline is 2 BUSINESS days, not 2 calendar days and not 10 days; the clock starts on the transaction date, not settlement.
• "On market terms" or "below market" does NOT save an insider loan; the ban is on the issuer-to-insider lending relationship itself, not the rate.
• A 10-K with only management's assessment is incomplete unless the company qualifies for the non-accelerated-filer or emerging-growth-company exemption from auditor attestation.

What Anchors the Disclosure Standard and Reasonable Investigation?

• Legal anchor: Securities Act civil liability for material defects in registration statements; Exchange Act antifraud liability independently reaches private placements.
• Six review categories: financial information, business plan, management interviews, third-party interviews (vendors, suppliers, customers), site visits, and bring-down due diligence.

How Do Sell-Side and Buy-Side Due Diligence Differ?

• Same eight comparison categories, opposite chairs: financial review, data room, management presentations, site visits, reverse due diligence, background checks, risk discovery, cost-saving identification. Reverse DD, background checks, and cost savings run on only one side.
• Sell-side BUILDS and HOSTS: diligences the seller first, assembles materials, indexes the virtual data room (VDR), monitors bidder access, then runs reverse due diligence on buyers.
• Buy-side CONSUMES and INSPECTS: coordinates the schedule with the buyer and the target, reads the data room, attends presentations and site visits, runs background checks and risk discovery, and pulls diligence from sources OTHER than the target (trade press, competitors, analysts, EDGAR, background-check vendors).
• Different goals: the seller wants the highest bid that will close (closing certainty); the buyer wants to pay no more than the business is worth (price discipline).

What Are the Sarbanes-Oxley Checkpoints?

Three checkpoints from Sarbanes-Oxley drop into any public-company target review. Think loans, reporting, controls:

• Personal-loan prohibition: the issuer may not extend personal loans to directors and executive officers; narrow exceptions only. Due diligence hook: related-party-transaction footnotes and board minutes.
• Accelerated insider reporting. Due diligence hook: pull recent Form 4 activity from EDGAR for buying or selling signals and late or missed filings.
• Internal control over financial reporting (ICFR) requires both management's assessment and the auditor's attestation. Due diligence hook: the Controls and Procedures section of the 10-K, watching for disclosed material weaknesses.

One-Breath Recap

Due diligence defends the Securities Act disclosure standard, which attaches liability to both an untrue statement of material fact and a material omission; non-issuer defendants escape it only by proving a reasonable investigation whose depth slides with the issuer, security type, the defendant's role, and reliance on knowledgeable personnel. On an M&A deal the same eight comparison categories line up on both desks with the verbs flipped: the sell-side banker indexes the data room and runs reverse due diligence on the buyers' ability to close, while the buy-side banker runs background checks and risk discovery (off-balance-sheet, unfunded liabilities) and hunts cost-saving synergies; layered on any public-company target are three Sarbanes-Oxley checkpoints, no issuer loans, Form 4 within two business days, and dual management-plus-auditor internal-control assertions.
