Q: 🏛️ Technical Framework: Setting "The Peg"

The Working Capital Peg is the technical benchmark against which the closing balance sheet is measured. * The TTM Method: Most Pegs are calculated using a Trailing Twelve Months (TTM) average. This smooths out seasonality (e.g., a toy store having massive inventory in November but zero in January)

引导语：Working Capital True-Up & Peg Mechanics（营运资金调整与基准机制）是并购交易完成后的“最终结算”。本文从净营运资金（NWC）基准（Peg）的设定、投后审计程序（True-up）以及正常业务过程（Ordinary Course）的法理判定三个维度，深度解析其如何防止卖方在交易前夕套取现金，并揭示了独立会计师（Independent Accountant）在解决数百万美元估值争议中的仲裁作用。

TL;DR: In an M&A transaction, the purchase price is based on the assumption that the company has a "Normal" level of Net Working Capital (NWC) on the day of closing. Since a business is dynamic, the exact amount of inventory, accounts receivable, and accounts payable fluctuates daily. To handle this, parties agree on a Working Capital Peg (a target level). After the deal closes, the Buyer performs a Post-Closing Audit (True-Up). If the actual NWC is higher than the Peg, the Buyer pays the Seller more; if it is lower, the Seller must wire money back to the Buyer (often from an Escrow Account).

Component	Technical Inclusion (Operating)	Forensic Exclusion (Non-Operating)
Accounts Receivable	Trade receivables from customers	Related party loans, tax refunds
Inventory	Raw materials, WIP, finished goods	Obsolete or damaged stock (Write-downs)
Prepaid Expenses	Insurance, rent paid in advance	One-time acquisition costs
Accounts Payable	Trade payables to suppliers	Professional fees for the merger
Accrued Liabilities	Wages, utility accruals	Dividends payable, interest payable
Deferred Revenue	Unearned income from customers	Long-term deferred tax liabilities

🏛️ Technical Framework: Setting "The Peg"

The Working Capital Peg is the technical benchmark against which the closing balance sheet is measured.

The TTM Method: Most Pegs are calculated using a Trailing Twelve Months (TTM) average. This smooths out seasonality (e.g., a toy store having massive inventory in November but zero in January).
Normalization Adjustments: Auditors must "strip out" non-recurring items. If the company had a one-time massive legal settlement last year that lowered its payables, that month must be adjusted upward to reflect the "Normal" working capital required to run the machine.
Forensic Risk: A Seller will try to set a Low Peg (making it easier to have an "excess" at closing), while a Buyer wants a High Peg (to ensure they get more inventory and cash-at-close).

⚙️ The Post-Closing Audit: Detection of "Looting"

The True-Up is technically designed to prevent the Seller from "Looting" the company between the signing and the closing.

Stretching Payables: If a Seller stops paying vendors for 3 months to build up $2M in extra cash, the accounts payable balance will skyrocket. Since NWC = Current Assets - Current Liabilities, the NWC will drop, triggering a Negative True-Up that forces the Seller to pay the $2M back to the Buyer.
Aggressive Collection: If the Seller offers massive discounts to customers to pay their bills early before the closing, the accounts receivable disappears and is replaced by cash. Under a "Cash-Free, Debt-Free" deal, the Seller keeps the cash, but the True-Up captures the "Missing AR" and adjusts the price downward.
Inventory Starvation: If the company stops buying raw materials, the production line will stop 10 days after the Buyer takes over. The True-Up audit identifies this "Missing Inventory" against the Peg and charges the Seller for it.

🛡️ Dispute Resolution: The Independent Accountant

When multi-million dollar adjustments are at stake, lawyers are replaced by accountants.

The Mandate: The purchase agreement (SPA) usually appoints an Independent Accountant (e.g., a Big 4 firm not involved in the deal).
The Scope: The accountant is technically an "Expert," not an "Arbitrator." They can only rule on the specific accounting disputes (e.g., "Is this $500k inventory obsolete?"), they cannot rewrite the contract.
The "Baseball" Method: In some deals, the accountant must pick either the Buyer's number or the Seller's number, with no "middle ground." This technically forces both sides to be as reasonable as possible.

🔍 Forensic Indicators of "Ordinary Course" Breaches

Investigators audit the closing period for deviations from the "Ordinary Course of Business":

Day Sales Outstanding (DSO) Analysis: If the DSO suddenly drops from 45 days to 20 days in the month before closing, it indicates aggressive/coercive collection.
Vendor Complaint Audit: Contacting top suppliers to see if they were told their payments were "On Hold" during the merger period.
Physical Inventory "Count-to-Book" Reconciliation: Physically verifying that the inventory listed on the estimated statement actually exists on the warehouse floor at the moment of closing.

Frequently Asked Questions (FAQ)

What is "Minimum Working Capital"?

Technically, it is a covenant in the SPA that forbids the Seller from allowing the NWC to drop below a certain level before the closing.

Who pays for the Independent Accountant?

Usually, the loser pays. If the accountant’s final number is closer to the Buyer’s number, the Seller pays the full fee.

What is a "Locked-Box" deal?

Technically, the opposite of a True-Up. In a Locked-Box deal, the price is fixed based on a past balance sheet, and no adjustments are made at closing. This is very popular in Europe but rare in the US.

Why include "Prepaid Expenses"?

Because the Buyer will get the benefit of the service (e.g., the insurance coverage) after the closing. The Seller has already paid for it, so it is an "Asset" they are leaving behind.

Conclusion: The Mandate of Final Reconciliation

Working Capital True-Up Reports are the definitive "Integrity Filter" of the M&A world. They prove that in a market of dynamic business cycles, The final price must reflect the final state of the machine. By establishing a rigorous framework of NWC Pegs, post-closing audits, and independent arbitration, the finance and legal teams ensure that neither party is "Games" the transition. Ultimately, True-Up mechanics ensure that corporate acquisitions are grounded in operational reality—proving that in the end, the most resilient deal is the one where the last dollar is settled by the numbers, not the promises.

Bilingual Summary: Working Capital True-Ups adjust the final price after closing to match the actual level of operational assets. 营运资金调整与基准机制报告（Working Capital True-Up & Peg）是并购交易中的“最终结算审计”。其技术核心在于“基准（Peg）比对”：买卖双方先设定一个正常业务下的营运资金基准（通常为过去 12 个月的平均值），并在交易完成后 60-90 天内进行深度审计。如果实际净营运资金（NWC）低于基准，卖方需向买方退还差价。对审计团队而言，核心在于识别卖方是否在交易前夕通过推迟支付供应商货款或提前收款等手段“榨取”公司现金。理解独立会计师（Independent Accountant）的仲裁机制是解决此类数百万美元争议的关键。
