A working capital adjustment is the post-closing purchase-price reconciliation mechanism in M&A transactions where the final purchase price is adjusted up or down based on the difference between the target company’s actual working capital at closing and a pre-agreed reference level (“target working capital” or “normalized working capital”). The mechanism aligns purchase-price economics with the operational reality of the business at closing — ensuring buyer receives a business with the working capital it expected based on diligence and seller is fairly compensated for any incremental working capital delivered.
The mechanic operates in two phases: (i) estimated closing statement (seller delivers an estimate of closing working capital 3–5 days before closing; purchase price is paid based on this estimate with any preliminary true-up); and (ii) final closing statement (within 60–120 days post-closing, the buyer prepares actual closing-balance-sheet figures audited per agreed methodology; final true-up payment moves between parties based on actual vs. target delta).
Working capital target setting is critical and heavily negotiated. Common methodologies include: trailing 12-month average (smoothing seasonal variations); trailing 6-month average (capturing more-recent business state); most-recent-month-end (simpler but volatile); and negotiated targets based on go-forward business plan. Each methodology produces materially different target levels — a seasonal business with high Q4 receivables may show 2x different working capital depending on whether 12-month or 3-month averaging applies.
Disputes are common in working-capital adjustments — second only to indemnification claims as the principal source of post-closing M&A litigation. Common dispute categories include: (i) accounting policy disputes (whether specific accruals follow GAAP/IFRS consistently with historical practice); (ii) inventory valuation (LIFO/FIFO methodology, obsolescence reserves, slow-moving inventory write-downs); (iii) AR reserves (allowance for doubtful accounts, aging classification); (iv) accrual completeness (litigation reserves, tax accruals, warranty accruals); and (v) cash vs. working-capital characterization (deferred revenue treatment, restricted cash inclusion).
For Turkish founders selling to international acquirers, working-capital adjustment design should account for: TRY-volatility creating short-term working capital fluctuations not reflective of business health, Turkish accounting differences (TFRS vs. IFRS vs. acquirer’s home GAAP), and the operational practicality of dual-language closing-statement preparation. Vircon Legal advises sellers and buyers on working-capital adjustment design — methodology negotiation, target-level setting, accounting-policy specification, dispute-resolution mechanic design (typically independent-accountant determination), and the integration of working-capital mechanics with overall purchase-price architecture.
