Working Capital Adjustments in M&A: The Technical Guide Buyers Don't Want You to Read

The purchase price in your LOI isn't the final number. Working capital adjustments—often buried in complex formulas—can swing the actual proceeds by millions. Understanding these mechanics is essential for any executive selling a company.

Why Working Capital Adjustments Exist

When you sell a company, you're transferring a going concern. The buyer expects the business to have enough working capital to operate normally without immediately injecting new cash.

The Core Principle: The buyer pays for the business assuming a "normal" level of working capital. If actual working capital at closing is higher or lower than that target, the purchase price adjusts accordingly.

The Basic Formula

Net Working Capital (NWC) = Current Assets - Current Liabilities

But the actual calculation is rarely this simple. The definition is negotiated and can include or exclude dozens of line items.

Typical Inclusions

Current Assets:

• Accounts receivable
• Inventory
• Prepaid expenses
• Other current assets

Current Liabilities:

• Accounts payable
• Accrued expenses
• Deferred revenue
• Other current liabilities

Common Exclusions

• Cash and cash equivalents (handled separately)
• Debt (handled separately)
• Income tax receivables/payables
• Intercompany balances
• Transaction-related items

Setting the Target

The "target" working capital is the baseline against which closing working capital is measured.

Methods to Set Target

1. Historical Average

Calculate NWC over 12-24 months and use the average. This smooths seasonality.

Example:

2. Normalized Working Capital

Adjust historical figures for non-recurring items, seasonality, or known changes.

3. Fixed Dollar Amount

Negotiate a specific number based on analysis and expectations.

Negotiation Dynamics

Sellers Want: Higher target (less adjustment risk), broader definitions

Buyers Want: Lower target (capture more value), tighter definitions

The Adjustment Mechanism

Dollar-for-Dollar Adjustment

Most deals use dollar-for-dollar adjustments:

• Closing NWC > Target → Purchase price increases
• Closing NWC < Target → Purchase price decreases

Example:

• Purchase price: $50M
• NWC Target: $2.5M
• Closing NWC: $2.8M
• Adjustment: +$300K
• Final proceeds: $50.3M

Collars and Baskets

Some deals include collars to avoid adjustments for small variances:

Collar Example:

• Target: $2.5M
• Collar: ±$100K
• If closing NWC is $2.45M-$2.55M, no adjustment
• If closing NWC is $2.3M, adjustment is $100K (not $200K)

Closing Mechanics

Estimated vs. Final Statement

At Closing:

• Seller prepares estimated closing balance sheet

• Parties agree on estimated NWC

• Purchase price adjusted based on estimate

Post-Closing (30-90 days):

• Buyer prepares final closing balance sheet

• Seller reviews and objects to disputed items

• Disputes resolved through negotiation or arbitration

• Final adjustment made (true-up payment)

The Review Period

Buyer's Rights:

• Access to books and records
• Time to prepare final statement (usually 60-90 days)
• Specify disputed items with detail

Seller's Rights:

• Review buyer's calculation
• Object to specific items
• Access to work papers and support

Common Manipulation Tactics

Buyer Tactics (to reduce closing NWC)

1. Aggressive Cut-off

• Booking revenue before it should be recognized
• Pushing expenses into the post-closing period
• "Discovered" liabilities that should have been accrued

2. Reclassification

• Moving items from current assets to non-current
• Reclassifying receivables as non-collectible

3. Policy Changes

• Applying more conservative accounting policies
• Increasing bad debt reserves
• Writing down inventory

4. Operational Manipulation

• Delaying vendor payments to inflate AP
• Accelerating customer collections to deflate AR

Seller Defenses

1. Lock in Definitions

Specify exactly which line items are included/excluded with granular detail.

2. Consistent Policies

Require calculation using "past practice" or "GAAP applied consistently."

3. Materiality Threshold

Include a threshold below which buyer cannot object.

4. Review Rights

Ensure robust access to buyer's work papers and calculations.

The Deferred Revenue Problem

Deferred revenue is particularly contentious because it reduces NWC but represents valuable future revenue.

The Issue

Seller's View: High deferred revenue is good—it's contracted future revenue.

Buyer's View: Deferred revenue is a liability requiring future performance. High deferred revenue means lower NWC, which triggers a negative adjustment.

Solutions

1. Exclude Deferred Revenue

Remove it from the NWC calculation entirely. This is seller-friendly but buyers often resist.

2. Normalize Deferred Revenue

Set the target based on average deferred revenue, so normal levels don't create adjustments.

3. Value-Based Adjustment

Adjust for deferred revenue at a different rate (e.g., 50% of face value) recognizing its partial value.

Inventory Adjustments

Inventory is another major battleground.

Valuation Methods

• **FIFO vs. LIFO**: Different methods = different values
• **Lower of Cost or Market**: Requires judgment on market values
• **Obsolescence Reserves**: Subjective estimates of unsaleable inventory

Physical Count

Most deals require a physical inventory count at or near closing. Issues include:

• Who conducts the count?
• What methodology?
• How are variances resolved?

Obsolete Inventory

Buyer Tactic: Claim large portions of inventory are obsolete, reducing NWC.

Defense: Define obsolescence criteria specifically in the purchase agreement (e.g., "inventory held > 18 months without sales").

Accounts Receivable Issues

Collectability Reserves

Buyers may attempt to increase bad debt reserves, reducing AR and NWC.

Defense: Specify reserve calculation methodology or cap reserve increases.

Aging Categories

Reclassifying receivables to older aging buckets can justify higher reserves.

Defense: Include detailed aging analysis in NWC schedules.

Customer Disputes

Buyers may claim previously unknown customer disputes make certain receivables uncollectible.

Defense: Require documentation of disputes, materiality thresholds.

Detailed Definition Checklist

Your purchase agreement should specify:

For Each Line Item

• [ ] Is it included or excluded from NWC?
• [ ] How is it valued/measured?
• [ ] What accounting policies apply?
• [ ] What supporting documentation is required?

General Provisions

• [ ] GAAP applied consistently with past practice
• [ ] Cut-off procedures specified
• [ ] Intercompany elimination rules
• [ ] Foreign currency conversion rules
• [ ] Treatment of reserves and allowances

Dispute Resolution

Negotiation First

Most agreements require good-faith negotiation before escalation.

Independent Accountant

If negotiation fails, disputes go to an independent accounting firm:

• Parties submit positions in writing
• Accountant reviews and decides
• Usually "baseball arbitration"—accountant picks one side's position
• Decision is final and binding

Cost Allocation

Typically:

• Prevailing party's costs paid by loser
• Or split based on proximity to final determination

Real-World Example

Scenario:

• $100M purchase price
• NWC Target: $8M
• Seller estimate at closing: $8.2M

Post-Closing:

Buyer delivers statement showing NWC of $6.5M, claiming:

• $500K additional bad debt reserve (AR aging concerns)
• $400K inventory obsolescence (slow-moving SKUs)
• $300K accrued liabilities (discovered obligations)
• $300K revenue recognition (overstated AR)
• $200K other adjustments

Seller Response:

• Bad debt: Historical rate is 2%, not 5%; request documentation
• Inventory: Products sold in last 6 months, not obsolete per defined criteria
• Accrued liabilities: Items existed pre-closing, already in estimate
• Revenue recognition: Challenge specific transactions, request customer confirmation

Resolution:

After negotiation and partial escalation, parties settle at $7.3M NWC, resulting in $700K negative adjustment ($8M target - $7.3M actual).

Final proceeds: $100M - $700K = $99.3M

Strategic Recommendations

Before Signing

• **Negotiate definitions exhaustively**: Every ambiguity favors the party calculating

• **Include detailed schedules**: Show exactly how NWC is calculated

• **Set appropriate targets**: Use normalized, seasonally-adjusted figures

• **Consider collars**: Reduce adjustment risk for both parties

Pre-Closing

• **Manage working capital**: Don't artificially inflate, but optimize timing

• **Document everything**: Clean records reduce disputes

• **Monitor buyer behavior**: Watch for manipulation signs

Post-Closing

• **Review buyer's calculation carefully**: Line by line

• **Object timely**: Don't miss deadlines

• **Document disputes**: Prepare for potential arbitration

• **Negotiate strategically**: Know your walk-away points
