An M&A buyer's-eye review of 4 top books on reading financial statements—ranked by how well they help non-accountants spot fraud and red flags during due diligence.
A working checklist for small M&A financial DD: the eight documents to request first with the purpose of each, statement-vs-tax-return reconciliation, balance verification, and how to build the question list — everything a buyer can do alone.
How much to spend on financial due diligence: the ¥500K–1M full-DD market rate, cost-effectiveness by deal size, the screen → narrow → outsource sequence, and scoped delegation — a budgeting guide for small M&A buyers.
For time-poor individual buyers: which numbers in the financial statements matter. Six values from roughly twelve line items — normalized EBITDA, net debt, CCC, current ratio, equity ratio, and operating margin — mapped to the exact BS/PL accounts.
Where a seller's statements distort: tax-driven profit compression (director pay, insurance, private expenses) versus appearance-driven dressing (pulled-forward sales, inflated inventory, double books) — which accounts each shows up in, and how reconciliation and turnover-day analysis detect them.
Finance-driven small M&A failures reduced to five patterns — profitable-but-broke, profit illusion, net-debt blind spot, off-balance liabilities, working-capital starvation — each mapped to the DD metric or procedure that detects it before closing.
How DD priorities shift between small M&A structures: a share deal universally succeeds to off-balance liabilities and tax risk, weighting DD toward liability hunting; an asset deal shifts the battleground to asset existence and unit-level earning power. With a comparison table and the exceptions.
A complete guide to buyer-run first-pass financial DD for small M&A deals. Drawing on three EXITs on the sell side of DD and building a financial DD tool: the six metrics, verification, process, and converting findings into price terms.
