Net Working Capital
The capital tied up in a business's operating cycle — typically defined as current assets (AR, inventory) minus current liabilities (AP, accrued expenses), excluding cash and debt — and one of the most negotiated purchase price adjustments.
Full Definition
Net working capital (NWC) funds the day-to-day operation of a business: customers owe you money (AR), you have product on shelves (inventory), and you owe vendors money (AP). The difference is the "investment" in working capital needed to operate. In M&A, NWC is transferred with the business — the buyer expects to receive a "normal" level of working capital so they can run operations from day one without additional investment.
How it actually works: The working capital mechanism: (1) parties agree on a "target" or "peg" — the normal level of NWC the business needs; (2) at closing, actual NWC is measured; (3) if actual is below peg, seller owes the shortfall (or it's deducted from proceeds); (4) if actual is above peg, buyer owes the surplus (or it's added to proceeds). Typical peg setting: 12-month average or 3-5 year average of NWC, with adjustments for growth trajectory.
What's in NWC: usually AR (customers owing money), inventory, prepaid expenses, AP (money owed to vendors), accrued expenses, customer deposits (if not treated as debt), and some other operating items. Excluded: cash (swept separately), interest-bearing debt (paid off separately), and specific debt-like items.
NWC normalization is critical: one-time spikes (Q4 AR from a big December sale, year-end inventory build for January promotion) shouldn't set the peg. Month-over-month averaging normalizes these.
Seller vs. Buyer Perspective
The working capital peg can move your proceeds by hundreds of thousands of dollars. Key leverage points: (1) peg methodology — insist on a reasonable averaging approach (typically 12-month average); (2) seasonal normalization — if your business is seasonal, the peg should reflect the average, not a specific high-point; (3) definition of items — work out specifically what's in NWC vs. debt vs. excluded; (4) collar or bands — some deals use "no adjustment" bands around the peg ($200K either way) to avoid nickel-and-dime disputes; (5) timing — closing date NWC vs. average of recent months can give different results. Prepare your NWC analysis before going to market — a well-documented peg framework is a negotiating advantage.
Working capital is one of the most reliable value-protection levers. Set the peg from a defensible average. Negotiate specific inclusions: aging AR should be reserved (or excluded); slow-moving inventory should be reserved; prepaids should be current. Items that behave like debt should be excluded from NWC (go to debt calculation instead). The peg is worth real money — $200K of below-peg shortfall is $200K off the seller's check. Measure carefully. Post-close, work with the seller's team to reconcile — disputes are common and should be resolved through agreed procedures.
Real-World Example
A $4M EBITDA business is being sold with $20M enterprise value. Working capital analysis: 12-month average NWC $2.1M, prior 3-year average $2.0M. Seasonality: Q4 spike due to year-end customer ordering, Q1 dip due to collections of Q4 receivables. Parties agree on peg of $2.1M with a $100K collar (no adjustment within $100K of peg). At closing: actual NWC $1.85M. Actual vs. peg: $250K below. Collar applied: $250K - $100K = $150K adjustment. Seller delivers $150K less at closing. Had the peg been $1.95M (prior year average only), the shortfall would have been only $100K, within the collar — zero adjustment. Setting the peg drove a $150K economic outcome. Three months post-close: working capital has normalized as Q1 collections come in. Had the parties closed in February instead of January, the calculation would have shown $2.1M NWC, matching peg.
Why It Matters & Common Pitfalls
- !Peg methodology. 12-month simple average is most common; weighted or adjusted averages are sometimes used for growing businesses.
- !Seasonality matters enormously. Monthly peg-to-closing comparisons can swing $500K+ on seasonal businesses. Normalize carefully.
- !AR aging reserves. Buyers often require AR over 90 days to be reserved or excluded. Seller should maintain clean collections.
- !Inventory valuation. Slow-moving or obsolete inventory should be reserved. Methodology (FIFO, LIFO, average cost) matters.
- !Prepaid expenses. Should be current items usable by new owner, not long-term rights.
- !Cutoff accounting. Period-end accruals, cutoff of revenue/expenses must be consistent with historical methodology.
- !Collars and bands. "No adjustment" bands around peg reduce small-dollar disputes. $100-200K bands are common.
- !Dispute resolution. Purchase agreement should specify how NWC disputes are resolved — typically independent accountant binding arbitration.

Related Terms
Working Capital Peg
The agreed target level of working capital the seller is expected to deliver at closing — the benchmark against which actual closing working capital is measured for purchase price adjustment.
Working Capital Adjustment
A purchase price adjustment comparing the business's working capital at closing to an agreed target (the "peg") — with any shortfall deducted from seller proceeds and any surplus added.
Post-Closing Adjustment
Reconciliation of estimated closing balances (working capital, debt, cash) to final actual amounts, with net difference paid between buyer and seller — typically finalized 60-120 days after closing.
Cash-free, Debt-free
A standard M&A pricing convention where the seller keeps all cash at closing and pays off all debt, so the purchase price reflects only the value of the operating business itself.
Locked Box
A pricing mechanism where the purchase price is fixed based on a pre-close "locked box" balance sheet date, with no post-closing working capital adjustment — common in European M&A, less common in US SMB deals.
