Vendor Due Diligence (VDD)

A comprehensive document prepared by the seller's advisors in an M&A sale process that provides prospective buyers with detailed information about the target business, including its history, products and services, market position, financial performance, management team, growth opportunities, and key risks. The IM is distributed to shortlisted parties after they have signed a non-disclosure agreement and is designed to enable buyers to form a preliminary valuation and submit indicative offers.

Statements of fact and assurances made by the seller (and sometimes the buyer) in an M&A sale and purchase agreement regarding the condition, operations, finances, and legal standing of the target business. Warranties cover areas including financial statements, material contracts, intellectual property ownership, litigation, tax compliance, and employee matters.

A non-binding expression of interest submitted by a prospective buyer in an M&A process, typically stating the proposed purchase price (or price range), the form of consideration, key assumptions, conditions to completion, and an outline timetable. Indicative offers are submitted after review of the information memorandum and before the buyer is granted access to the full data room for confirmatory due diligence.

A specialist insurance policy used in M&A transactions that covers losses arising from breaches of the seller's warranties and representations in the sale and purchase agreement. W&I insurance shifts the risk of warranty claims from the seller to an insurer, enabling cleaner exits for sellers and reducing the need for escrow holdbacks.

A specialist insurance product used in M&A transactions that covers the buyer against financial losses arising from breaches of the seller's warranties and representations in the sale and purchase agreement. W&I insurance has become standard in European PE transactions, enabling cleaner exits (as the seller's liability is capped or eliminated), facilitating auction processes, and allowing PE funds to distribute sale proceeds to LPs without retaining escrow reserves.

A common M&A pricing convention in which the enterprise value is expressed before accounting for the target's cash balances and debt obligations, which are then adjusted at completion to calculate the equity value payable to the seller. Under this convention, equity value equals enterprise value plus cash and cash equivalents less financial debt (including debt-like items such as pension deficits, deferred consideration, and unpaid tax).

A disclosure letter is the document a seller delivers alongside the sale and purchase agreement to qualify the warranties they are giving. Warranties are statements that the business is in a particular condition; the disclosure letter sets out the exceptions — the facts that make a warranty untrue or partly untrue — so that the buyer takes the business knowing about them and cannot later claim for what was disclosed.

A formal written assessment, typically prepared by an independent investment bank or valuation firm, evaluating whether the financial terms of a proposed transaction are fair to a company's shareholders from a financial point of view. Fairness opinions are standard practice in M&A transactions and are relied upon by boards of directors to discharge their fiduciary duties.
