Business Valuation and Due Diligence

01Purpose and scope

• This manual supports the course Business Valuation and Due Diligence. It is written for analysts, deal team members, lenders, and advisors who need to estimate what a private or public business is worth and to test whether the information behind that estimate holds up. It describes how the work is usually done, what decisions it feeds, and where the judgment calls sit.
• The scope covers valuation of operating companies and their equity or enterprise value, plus the due diligence that supports a transaction, financing, or internal decision such as a buy-in, a partner exit, or a purchase price allocation. It does not cover fairness opinions in detail, litigation support, or tax valuations, which carry their own rules and reporting obligations.
• This guidance does not replace qualified professional judgment, approved firm procedures, or any authorization required before work is issued. Rules differ by jurisdiction and by the type of engagement, so confirm the current requirements with the relevant securities regulator, tax authority, or professional body before relying on a conclusion.

02Core principles

• A valuation answers a specific question for a specific purpose at a specific date. The standard of value, the premise of value, and the level of ownership interest all change the answer. A controlling interest in a manufacturing business is not worth the same as a minority stake with no say over dividends, and an orderly sale assumption gives a different result than a forced liquidation.
• Earnings and cash flow are the raw material, but they are not accepted at face value. Normalize the reported figures for owner compensation, one-time legal costs, related party rents, and accounting policy choices before using them. The adjustments should be documented well enough that another analyst could reproduce them from the source records.
• Diligence is the process of confirming what the seller says and finding what the seller did not mention. It is not a search for a single bad fact. It is a structured test of revenue quality, cost structure, working capital needs, debt-like items, contingent liabilities, and the people and contracts that keep the business running.
• Consistency matters more than sophistication. A simple model with clear, sourced inputs and stated sensitivities is more useful to a decision maker than a complex model whose assumptions cannot be traced.

03Planning and preparation

• Start by defining the engagement: who the client is, what decision the work supports, the valuation date, the standard of value, and the expected deliverable. Write these down in an engagement letter or scope memo. Ambiguity here causes the most rework later, because the analyst may build a fair market value model when the buyer needs an investment value for a specific strategic owner.
• Request an information list early. A useful list covers three years or more of audited or reviewed financial statements where available, monthly management accounts for the current year, a customer revenue breakdown, the top supplier contracts, payroll registers, the debt schedule, tax returns, fixed asset registers, litigation history, and any projections with the assumptions behind them. Track what is received, what is late, and what is refused.
• Set the timeline against the transaction calendar. Exclusivity periods, lender deadlines, and board meeting dates often drive the schedule more than the analysis does. Agree on a point at which the team will stop expanding scope and report what it has, with open items clearly flagged.
• Identify the people who must be interviewed: the owner or chief executive, the finance lead, the sales leader responsible for the largest accounts, operations management, and outside advisors such as the accountant and counsel. Their availability frequently sets the real limit on the work.

04Recommended workflow

1. 1
   : Confirm the engagement terms, valuation date, standard of value, and conflicts of interest before any data review begins. Record the sign-off in the file.
2. 2
   : Collect the information list and perform an initial completeness review. Note missing periods, unexplained restatements, and documents that appear to have been edited.
3. 3
   : Reconcile the financial statements to the general ledger, tax returns, and bank statements for at least a sample of periods. Confirm that revenue in the management accounts ties to invoicing and cash receipts.
4. 4
   : Normalize historical earnings. Build a schedule of adjustments with source references, and separate recurring items from truly nonrecurring ones. Be cautious about adding back costs that keep recurring under a different label.
5. 5
   : Analyze revenue quality. Review customer concentration, contract terms, renewal rates, pricing history, and backlog. Compare reported growth with volume and price changes where data allows.
6. 6
   : Assess working capital, capital expenditure needs, and the normal level of cash the business requires to operate. Identify debt-like items such as deferred revenue, accrued bonuses, unpaid taxes, and customer deposits that affect the equity bridge.
7. 7
   : Build the valuation. Apply one or more methods, usually an income approach such as a discounted cash flow, a market approach using guideline public companies or transactions, and an asset-based check where the business holds significant tangible assets. Reconcile the indications and explain the weight given to each.
8. 8
   : Test sensitivity. Vary the discount rate, terminal growth or exit multiple, margin assumptions, and the timing of key revenue items. Show the range of outcomes and which inputs move the answer most.
9. 9
   : Prepare the diligence findings and valuation report, separating facts confirmed from sources, management representations not yet verified, and matters that need legal, tax, or technical review by specialists.

05Quality checks, risk controls and compliance

• Every model needs an independent review before it is issued. The reviewer should trace inputs to source documents, recalculate key formulas, and challenge any assumption that differs materially from historical performance or industry data. Keep a review log that records questions raised and how each was resolved.
• Valuation methods draw on professional standards. The International Valuation Standards issued by the International Valuation Standards Council and the Uniform Standards of Professional Appraisal Practice published by The Appraisal Foundation are two widely used frameworks. Whether a given standard applies depends on the engagement type, the jurisdiction, and the credentials held, so check which one governs before the report is finalized.
• Financial reporting valuations, such as those for purchase price allocation or goodwill impairment testing, follow accounting rules set out in the relevant accounting standards. Those rules change, and the current text should be checked rather than relying on memory or prior engagements.
• Risk controls include conflict checks, confidentiality agreements for data rooms, restrictions on contacting customers or employees without consent, and clear rules on who may communicate with the client about preliminary numbers. Material findings such as potential fraud, environmental liabilities, or unpaid taxes should be escalated under the firm's procedures and, where required, to the client's governance body.
• Regulated activities, including any advice on securities, lending decisions, tax positions, or fairness to shareholders, require qualified professionals and may need formal authorization. This manual is a working reference and does not substitute for those approvals.

06Collaboration and documentation

• Valuation and diligence work involve several roles. The lead analyst owns the model and the narrative. A diligence lead manages the information requests, interview notes, and findings register. Specialists in tax, legal, environmental, or information technology review their own areas and provide written conclusions. The engagement partner or manager approves the final output and any departure from standard procedure.
• Keep a single index of documents received, with dates of receipt, version numbers, and who provided them. Many disputes later turn on whether a particular forecast or schedule was available at the valuation date, so the file should show what the team knew and when.
• Interview notes should be written up within a day and reviewed by a second person when they touch on material facts. Record the attendees, the questions asked, and any statements the interviewee later qualified.
• Reports should separate the conclusion from the reasoning. State the valuation date, purpose, standard of value, scope limitations, key assumptions, sources, and the main sensitivities. Name who may rely on the report and for what purpose. Where scope was limited by the client, say so plainly.

07Measures and continuous improvement

• Track indicators that show whether the work is reliable and timely. Useful measures include the percentage of information requests fulfilled by the agreed date, the number of material adjustments made after the draft report, the variance between indicated values from different methods, the number of review comments that changed the conclusion, and the time from engagement start to first draft.
• Compare the realized outcome of past transactions with the value and risk assessments made at the time. Where the business later missed projections, examine whether the cause was a flawed assumption, a failure to test management's forecasts, or an event that could not reasonably have been anticipated. Feed those lessons into checklists and model templates.
• Improve templates and review checklists after each engagement. Retire steps that do not add information and add steps where a recurring problem appeared, such as a standard test for related party transactions or a standard review of customer contract assignment clauses.
• Be realistic about limits. Measures based on small samples can mislead, and a clean outcome does not prove the method was sound. Use the indicators to prompt discussion, not to score individual analysts.

08Common mistakes and how to prevent them

• Relying on management's adjusted earnings without testing them is the most frequent error. Prevent it by building the adjustment schedule from source records and asking for the support behind each add-back.
• Using a single valuation method and presenting the result as precise invites challenge. Reconcile at least two approaches where the data supports them, and show the range.
• Ignoring debt-like items moves the equity value by amounts that surprise clients after closing. Build the equity bridge with a written list of cash, debt, and debt-like items agreed with the client before the report is issued.
• Assuming a forecast is reasonable because it is detailed. Test the drivers: unit volumes, pricing, hiring plans, and capital spending should each tie to historical patterns or documented plans.
• Letting the deal timeline override scope. Agree in advance which gaps will be reported as limitations rather than filled with assumptions that the team cannot support.
• Failing to document the valuation date and the information available at that date. Set up the document index on day one and update it as materials arrive.

09Practical checklist

• Confirm the engagement scope, standard of value, valuation date, and conflict clearance in writing.
• Issue the information request list and log each item as received, late, or refused.
• Reconcile financial statements to the ledger, tax filings, and bank records for sampled periods.
• Prepare a sourced schedule of normalization adjustments and mark recurring items.
• Review revenue concentration, contract terms, renewal history, and pricing trends.
• Identify working capital needs, capital expenditure requirements, and debt-like items.
• Apply at least two valuation approaches where data allows and reconcile the indications.
• Run sensitivity tests on discount rate, terminal assumptions, margins, and key revenue timing.
• Obtain independent review and record the questions raised and their resolution.
• Confirm the applicable professional standards, accounting rules, and jurisdictional requirements with current authoritative sources.
• Document the reliance parties, limitations, and assumptions in the report before issue.
