Understanding Working Capital Adjustments
Understanding working capital adjustments is crucial for anyone involved in mergers and acquisitions. These adjustments determine how much value actually changes hands during a business sale. Without the right approach, buyers or sellers can lose millions due to simple miscalculations.
What Are Working Capital Adjustments?
Working capital adjustments are calculations that compare a company’s current assets and current liabilities at closing. The goal is to ensure both buyer and seller receive fair value. In simple terms, working capital is:
Component | Example Items |
Current Assets | Accounts receivable, inventory, prepaid expenses |
Current Liabilities | Accounts payable, accrued expenses |
Working capital adjustments focus on the net difference between these two categories. For example, if a business has $500,000 in receivables, $300,000 in inventory, and $200,000 in payables, the working capital is $600,000.
Over 80% of M&A transactions include a working capital adjustment clause, according to the 2026 Working Capital Purchase Price Adjustment Study. This adjustment ensures the business operates smoothly after the sale.
The purpose of working capital adjustments is to prevent a situation where the buyer receives less working capital than expected, or the seller leaves excess value on the table. For example, in the Westinghouse vs. Chicago Bridge & Iron case, a $2 billion dispute arose over the calculation of working capital at closing.
Here’s a step-by-step guide to how working capital adjustments work:
Both parties agree on a target working capital amount before closing.
At closing, the actual working capital is measured.
If the actual amount is above or below the target, the purchase price is adjusted accordingly.
Typical components include:
Accounts receivable
Inventory
Prepaid expenses
Accounts payable
Accrued liabilities
Working capital adjustments play a direct role in determining the final purchase price. Without them, either party risks significant financial loss.
Why Are They Essential in M&A Transactions?
Working capital adjustments are essential in M&A because they protect both parties from unfair outcomes. Without these adjustments, the buyer could end up with too little working capital, leading to immediate cash needs, or the seller might lose value by leaving excess assets in the business.
Benefits of working capital adjustments include:
Preventing buyer windfalls or seller disadvantages
Maintaining operational stability after the sale
Reducing the need for post-closing capital injections
Statistics show that disputes over working capital can delay deal closings by an average of 60 days. This delay can disrupt operations and erode trust between parties.
A common scenario: If a business is sold during a seasonal high, the working capital might be artificially inflated. Adjustments ensure the buyer does not overpay for temporary spikes in assets.
Key reasons working capital adjustments matter:
They ensure a fair value exchange by adjusting the purchase price to reflect the actual state of the business at closing.
They address cash flow volatility and seasonality, which can impact the business’s ability to operate post-transaction.
They help avoid disputes that can escalate into costly legal battles.
In summary, working capital adjustments are a cornerstone of any well-structured M&A deal. They provide transparency, protect value, and keep transactions on track.
Key Components of Working Capital Calculations
Working capital adjustments are a critical piece of dealmaking. When calculated correctly, they can protect both buyers and sellers from value loss. However, mistakes or ambiguity in calculations often become a source of costly disputes. Understanding the components, industry nuances, and accounting standards behind working capital adjustments is essential for a smooth transaction.
Standard Inclusions and Exclusions
Working capital adjustments typically rely on a clear set of inclusions and exclusions. The most common inclusions are:
Accounts receivable
Inventory
Prepaid expenses
Exclusions often include:
Cash (retained by seller in 90% of deals)
Long-term debt
Intercompany balances
Table: Example Working Capital Calculation
Current Assets | Amount ($) | Current Liabilities | Amount ($) |
Accounts Receivable | 600,000 | Accounts Payable | 350,000 |
Inventory | 400,000 | Accrued Liabilities | 90,000 |
Prepaid Expenses | 30,000 | ||
Total | 1,030,000 | Total | 440,000 |
Net Working Capital = $1,030,000 - $440,000 = $590,000
Real-world example: In asset sales, sellers generally retain cash, while in equity sales, some cash may remain in the business. This distinction directly impacts working capital adjustments and deal value.
Buyers and sellers should agree early on what to include. Misalignment can quickly escalate into disputes.
Adjustments for Industry and Deal Structure
Working capital adjustments are not one-size-fits-all. Each industry has unique needs:
Retail: High inventory, frequent turnover, potential for seasonal spikes.
Manufacturing: Large inventory, work in progress, longer receivable cycles.
Services: Lower inventory, higher prepaid expenses.
Deal structure also matters. Asset transactions may exclude certain liabilities, while share deals carry all existing obligations.
Step-by-Step Guide for Seasonality Adjustments:
Gather 12 months of historical working capital data.
Calculate the average for each period.
Adjust for any outliers or unusual events.
Use the average as the working capital target to avoid seasonal distortions.
Example: A retail business with holiday season spikes should avoid setting targets based only on December figures. Averaging the year gives a fairer benchmark.
Buyers typically want a conservative target, while sellers prefer a higher one. Both sides benefit from transparency and data-driven negotiation. For further strategies on optimizing value with working capital adjustments, see the ultimate guide to maximizing business value.
Accounting Standards and Measurement Consistency
Consistency is vital in working capital adjustments. Using different accounting standards or methods can trigger disputes.
Use agreed standards: Most deals specify GAAP or IFRS.
Align measurement approaches: Both parties should agree on reserves for bad debt, inventory obsolescence, and accruals.
Attach sample calculations: Include a historical working capital schedule as an exhibit.
Table: Dispute Sources Due to Inconsistency
Source of Dispute | % of Cases |
Different accounting methods | 65% |
Ambiguous inclusions/exclusions | 25% |
Seasonality miscalculations | 10% |
Real-world example: A seller omits a bad debt reserve, while the buyer includes it. This difference can lower the final price by thousands.
Best practice: Always reference historical balance sheets and attach clear schedules. This reduces ambiguity and protects both parties from costly misunderstandings.
Setting the Working Capital Target: Step-by-Step Guide
Setting an accurate working capital target is critical for successful working capital adjustments in any transaction. Each step should be data-driven, transparent, and tailored to your business. This guide provides a clear, actionable process for both buyers and sellers to follow.
Step 1: Determine the Normalized Working Capital Level
Begin by analyzing at least 6 to 12 months of historical working capital data. This helps identify trends, seasonality, and anomalies. Adjust the data for any unusual events, such as rapid growth, new product launches, or extraordinary expenses.
Calculate monthly working capital balances.
Adjust for seasonality if your business is cyclical.
Remove any one-off or non-recurring items.
Averages are often used. For example, a retail business may see spikes in inventory before holidays, while a SaaS company has steadier levels.
Table: Example of 12-Month Working Capital Averages
Month | Working Capital ($) |
Jan | 1,000,000 |
Feb | 1,050,000 |
... | ... |
Dec | 1,200,000 |
Average | 1,110,000 |

Step 2: Define the Calculation Methodology
Clearly define how working capital adjustments will be calculated. Specify the accounting standards to be used, such as GAAP or IFRS, and agree on which items are included or excluded.
List all inclusions (accounts receivable, inventory, prepaid expenses).
Exclude items like cash (in 90% of deals), long-term debt, or tax liabilities.
Attach a calculation schedule for transparency.
Statistic: 78% of successful deals use a defined calculation schedule.
Example: In an asset sale, only assets transferred are counted. In a share sale, all current assets and liabilities are typically included.
Inconsistent calculation methods can lead to disputes. Ensure both parties use the same definitions and measurements for accurate working capital adjustments.
Step 3: Negotiate the Working Capital Range or Collar
Rather than setting a fixed number, negotiate a range or "collar" for the working capital target. This reduces the need for micro-management before closing and allows for normal operating fluctuations.
Agree on a target range, such as $1 million to $1.2 million.
Only adjust the purchase price if the actual working capital falls outside this range.
Both buyer and seller benefit from reduced uncertainty.
Statistic: Deals with collars result in 25% fewer post-closing disputes.
Example: If closing working capital is $1.15 million, no adjustment occurs. If it is $900,000, the purchase price is reduced.
Working capital adjustments structured this way protect both parties from minor fluctuations.
Step 4: Draft Clear Contractual Language
Precise, unambiguous contract language is essential. Attach a sample calculation as an exhibit, and reference historical balance sheets to clarify expectations.
Use defined terms for all components and calculations.
Specify the accounting standards and any exceptions.
Include a detailed schedule with historical data.
Best practice: Add a dispute resolution mechanism, such as third-party arbitration, within the contract.
Ambiguity in documentation is a leading cause of working capital adjustments disputes. Clear language and exhibits can prevent costly misunderstandings.
Step 5: Align on Post-Closing Adjustment Process
Agree on a post-closing true-up process, including timelines and procedures for submitting calculations and resolving discrepancies.
Set a timeline (30–90 days is standard) for post-closing review.
Outline the process for submitting working capital calculations.
Define how disagreements will be managed and resolved.
Statistic: 85% of disputes are resolved within 60 days when clear processes are in place.
Real-World Example: In one transaction, the seller guaranteed collection of receivables for 90 days post-closing, reducing risk for both parties.
By following these steps, you can master working capital adjustments and ensure a smoother, value-protecting transaction.
Common Pitfalls and How to Avoid Them
Understanding the most frequent pitfalls in working capital adjustments can help you avoid costly mistakes. According to Navigating Working Capital in M&A Transactions, even experienced dealmakers can fall victim to these traps, leading to value erosion and post-sale disputes.
Inconsistent Measurement Standards
A common pitfall in working capital adjustments is inconsistent measurement standards between buyer and seller. This issue often arises when each party uses different accounting methods or fails to align on key definitions.
Sellers may exclude bad debt reserves while buyers include them.
Inventory valuation can differ, with one party using FIFO and the other LIFO.
Unrecorded liabilities can skew the numbers.
Example Table: Impact of Measurement Differences
Component | Seller's Books | Buyer's Books |
Accounts Receivable | $500,000 | $450,000 |
Inventory | $300,000 | $270,000 |
Accrued Liabilities | $50,000 | $70,000 |
This inconsistency can result in a significant purchase price adjustment. To avoid this, always document the agreed accounting standards for working capital adjustments in the contract.
Poorly Defined Working Capital Targets
Setting vague or outdated targets is another source of disputes in working capital adjustments. Relying solely on historical averages without adjusting for business growth or seasonality can misrepresent true needs.
40% of disputes stem from ambiguous targets.
Ignoring recent growth or downturns skews the baseline.
Failing to account for cyclical trends leads to unfair adjustments.
Step-by-Step Guide: Setting Accurate Targets
Review at least 12 months of working capital data.
Adjust for any extraordinary or one-off events.
Factor in seasonality and recent growth trends.
Agree on clear calculation methods before signing.
By following this process, parties can minimize misunderstandings and set realistic working capital adjustments.
Excluding or Including the Wrong Items
Incorrectly including or excluding items is a frequent pitfall in working capital adjustments. For example, cash is typically excluded from working capital, but tax liabilities and intercompany balances are sometimes mishandled.
Cash is excluded in 90% of deals.
Tax liabilities should not be counted unless specifically agreed.
Intercompany balances can distort the calculation if not properly addressed.
Asset Sale Example: In an asset sale, failure to exclude unassumed liabilities can leave the buyer responsible for unexpected obligations. Always create a checklist of inclusions and exclusions to ensure accurate working capital adjustments.
Lack of Dispute Resolution Mechanisms
Another major pitfall is the absence of a clear dispute resolution process for working capital adjustments. Without agreed-upon mechanisms, disputes can escalate to costly litigation.
Deals lacking dispute clauses cost 30% more to resolve on average.
Delays can extend closing by months.
Step-by-Step Dispute Resolution:
Set a timeline for initial reconciliation (e.g., 30 days post-closing).
Allow both parties to review and respond within a set period.
Escalate unresolved issues to an independent accountant.
Finalize the adjustment and payment.
Including these steps in your contract can prevent unnecessary delays and expenses.
Manipulation of Working Capital Pre-Closing
Sellers may attempt to manipulate working capital adjustments before closing to maximize proceeds. Common tactics include accelerating receivables or delaying payables.
Shipments may be pushed out before closing to inflate receivables.
Payments to suppliers are postponed, reducing liabilities.
Real-World Example: In a recent transaction, the seller shipped unusually large orders right before closing. This temporarily boosted working capital by $400,000, leading to a significant post-sale dispute.
Prevention Steps:
Monitor working capital trends in the months leading up to closing.
Agree on average or normalized working capital calculations.
Include contractual language prohibiting unusual transactions.
By staying vigilant, both buyers and sellers can ensure fair working capital adjustments and protect deal value.
Negotiating and Finalizing Working Capital Adjustments
Getting working capital adjustments right is crucial for a smooth transaction closing. A significant portion of post-sale disputes arise from unclear terms, inconsistent data, or poorly documented processes. Buyers and sellers must approach negotiations with careful planning, accurate data, and a clear understanding of best practices.
Best Practices for Buyers and Sellers
Both buyers and sellers benefit from a proactive approach to working capital adjustments. Early preparation reduces risk and builds trust.
Start negotiations at the letter of intent stage.
Use independent advisors for complex calculations.
Share detailed working capital schedules and backup documentation.
Leverage historical averages and adjust for seasonality.
Include a clear dispute resolution mechanism in the agreement.
Statistics show that deals using third-party advisors experience 25% fewer disputes. For more insights on how working capital adjustments fit into different deal structures, see this overview on common business exit strategy types.
Key Negotiation Points
Successful working capital adjustments require clarity and transparency on several fronts. Here are the most common negotiation points:
Target Level: Should reflect a normalized average from the past 6–12 months.
Range or Collar: Agree on a range (e.g., $1M to $1.2M) rather than a fixed target to allow for natural business fluctuations.
Treatment of One-Off Items: Identify and agree on how to handle unusual receivables, payables, or inventory counts.
Accounting Standards: Specify whether GAAP, IFRS, or another method will be used.
Negotiation Point | Buyer Focus | Seller Focus |
Target Level | Avoid overpaying | Maximize payout |
Range/Collar | Reduce post-close risk | Limit exposure |
One-Off Items | Exclude liabilities | Include assets |
A study found that 90% of M&A deals include a working capital adjustment clause. For a legal perspective on structuring these terms, review Net Working Capital Adjustments in M&A Deals: The Buyer's Perspective.
Documenting the Adjustment in the Purchase Agreement
Precise documentation is the backbone of enforceable working capital adjustments. Contracts should always:
Define all calculation methodologies and accounting standards.
Attach a sample calculation and at least 12 months of historical data as exhibits.
Specify clear timelines for post-closing true-up and payment.
Include a step-by-step dispute resolution process.
Best practice: Add a detailed schedule outlining inclusions, exclusions, and adjustment procedures. Deals with robust documentation resolve disputes 85% faster on average.
Real-World Case Studies and Outcomes
Real-world examples highlight how working capital adjustments impact deal outcomes:
Westinghouse vs. Chicago Bridge & Iron: A $2 billion dispute over working capital calculations delayed closing by months and resulted in litigation.
Mid-Market Deal: A seller that manipulated inventory levels pre-closing faced a 10% purchase price reduction after the buyer’s post-closing review.
Successful Negotiation: In a recent transaction, both parties agreed on a collar and attached detailed schedules, leading to a smooth closing and no post-sale disputes.
Step-by-step negotiation, clear documentation, and transparent processes significantly reduce risk. By mastering working capital adjustments, both buyers and sellers protect value and avoid costly mistakes.
