Funds Flow in M&A: How Money Moves at Closing

What Is a Funds Flow Statement?

A funds flow statement — also called a funds flow memo or closing funds flow — is the document that maps exactly how money moves on closing day. It identifies every source of funds (who is putting money in), every use of funds (who is receiving money), and the precise amounts and wire instructions for each transfer.

In a straightforward acquisition, the funds flow might fit on a single page: buyer sends purchase price to seller, minus an escrow deposit. In a leveraged transaction with rollover equity, working capital adjustments, multiple holdbacks, and transaction expense reimbursements, the funds flow can run to ten or more pages and involve a dozen separate wire transfers.

The funds flow memo is not a legal formality. It is the operational blueprint for closing. Every dollar must balance — total sources must equal total uses — and every party must agree on the numbers before a single wire is sent. Errors in the funds flow are among the most common causes of closing delays, and in cross-border transactions, they can trigger regulatory complications that are difficult to unwind.

Why Funds Flow Matters

Most of the attention in an M&A transaction goes to negotiating the definitive agreement — the purchase price, reps and warranties, indemnification provisions, and closing conditions. But the funds flow is where those negotiated terms translate into actual money movement. It is the last major workstream before closing, and the one most likely to surface errors that should have been caught earlier.

Three things make funds flow critical:

Closing certainty. A well-prepared funds flow memo, circulated early and reviewed by all parties, reduces the risk of last-minute disputes over amounts. When the funds flow is left until the final 48 hours, it becomes a source of friction that can delay closing by days or weeks.

Fraud prevention. Wire fraud targeting M&A closings has increased sharply. The FBI’s Internet Crime Complaint Center reported US$2.9 billion in business email compromise losses in 2023, with real estate and M&A transactions among the most targeted categories. Funds flow memos with verified wire instructions and callback procedures are a primary defense.

Regulatory compliance. In cross-border M&A, funds often flow through multiple jurisdictions with different anti-money laundering (AML) requirements, foreign exchange controls, and tax withholding obligations. The funds flow memo must account for these — a transfer that violates foreign exchange regulations cannot simply be reversed.

Anatomy of a Funds Flow Memo

A standard funds flow memo has two sections: sources and uses. These must balance exactly.

Sources of Funds

Sources identify where the money originates. In a simple cash acquisition, there may be a single source. In a leveraged transaction, there are typically several:

Source	Description
Buyer equity	Cash contributed by the buyer (or its sponsor) from available capital
Debt financing	Senior secured loans, drawn on closing day per the credit agreement
Mezzanine financing	Subordinated debt or preferred equity, drawn at closing
Seller financing	Vendor takeback notes — the seller effectively lends part of the purchase price
Rollover equity	Existing shareholders who retain equity in the new structure (no cash changes hands, but it appears as a non-cash source and use for balancing)

In an LBO, the debt component is often 50-70% of total sources. The funds flow must reference the exact credit facilities being drawn, the drawdown amounts, and the sequence — senior lenders typically require their funds to flow first.

Uses of Funds

Uses identify every recipient and the amount they receive:

Use	Description
Seller proceeds	Net cash to the selling shareholders after all deductions
Escrow deposit	Funds held by an escrow agent to cover post-closing indemnification claims
Holdback	Amounts retained by the buyer pending satisfaction of specific conditions
Transaction expenses (seller)	Seller’s advisory fees, legal fees, accounting fees, transfer taxes
Transaction expenses (buyer)	Buyer’s advisory fees, legal fees, financing costs
Existing debt payoff	Repayment of the target’s outstanding debt at closing
Working capital adjustment	Estimated adjustment if closing working capital differs from the agreed peg
Tax withholding	Amounts withheld for applicable taxes (capital gains, withholding on cross-border payments)
Rollover equity (non-cash)	Balancing entry for shareholders rolling over their equity

The most common source of errors is the “waterfall” of deductions from the headline purchase price. A seller expecting to receive $100 million may net $80 million after debt repayment, escrow, holdbacks, working capital adjustments, and transaction expenses. The funds flow makes this visible — and it is often the first time the seller fully appreciates the gap between headline price and cash in hand.

The Funds Flow Process: Step by Step

1. Start Early

The funds flow memo should be initiated at the same time as the SPA drafting process — not as an afterthought once the deal terms are agreed. The American Bar Association’s Model Asset Purchase Agreement recommends that funds flow preparation begin alongside the definitive agreement negotiations, as many of the same economics (purchase price adjustments, escrow amounts, expense allocations) feed directly into both documents.

2. Map the Transaction Structure

Before drafting amounts, map the structural flow: Where are the entities? Which entity is the buyer? Which is the target? Are there intermediate holding companies or special purpose vehicles? In a cross-border deal, funds may need to flow through multiple entities in different jurisdictions to comply with foreign exchange regulations and optimise tax treatment.

3. Calculate the Numbers

The funds flow amounts depend on final calculations that are often not available until days before closing:

• Estimated working capital adjustment: Derived from the target’s most recent financial data, compared against the working capital peg agreed in the SPA
• Net debt calculation: Outstanding borrowings minus cash on hand as of the closing date
• Transaction expense tallies: Final invoices from advisors and legal counsel on both sides
• Tax computations: Withholding amounts, transfer taxes, stamp duties

4. Collect and Verify Wire Instructions

Every recipient provides wire instructions: bank name, account number, routing number (or SWIFT code for international transfers), and account holder name. These must be verified independently — not by replying to the email that delivered them, but through a separate channel (phone callback to a known number).

As Paul Weiss partner Robert Schumer has noted, “The closing mechanics are where months of negotiation either come together or fall apart. Wire instruction verification alone has prevented millions in misdirected funds.”

5. Circulate, Review, Reconcile

The draft funds flow is circulated to all parties: buyer, seller, their respective counsel, the escrow agent, and the lenders. Each party verifies the amounts relevant to them. Discrepancies are flagged and resolved. The final version is signed off by all parties — typically one to two business days before closing.

6. Execute on Closing Day

On closing day, the sequence matters. Lender funds are typically drawn first (the credit agreement may require evidence that all conditions precedent are satisfied before funding). The buyer then aggregates all sources and distributes funds per the memo. The escrow agent confirms receipt. Once all wires are confirmed, closing certificates are exchanged and the transaction is legally complete.

Working Capital Adjustments and True-Ups

Most mid-market and larger transactions use a working capital peg mechanism to ensure the buyer receives a business with a “normal” level of working capital at closing. The funds flow incorporates an estimated working capital adjustment based on the most recent available data.

The actual working capital is calculated post-closing — typically within 60 to 90 days — using completion accounts. If the actual working capital exceeds the estimate, the buyer pays the seller the difference (a “true-up” payment). If it falls short, the seller pays the buyer.

This post-closing true-up is not part of the closing funds flow itself, but the estimated adjustment at closing can be significant — often several million dollars in mid-market deals. Getting the estimate wrong creates friction: sellers dislike writing checks after they have already cashed out, and buyers dislike the exposure.

An alternative approach is the locked box mechanism, common in European and increasingly in Asia Pacific transactions. Under a locked box, the price is fixed to a historical balance sheet date, and there is no post-closing working capital adjustment. The funds flow is simpler — but the seller must avoid “leakage” (value extraction from the business) between the locked box date and closing.

Cross-Border Funds Flow in Asia Pacific

Cross-border M&A in Asia Pacific introduces layers of complexity to funds flow that domestic transactions do not face. Based on what we see at Amafi, these are the most common friction points:

Foreign exchange controls. Several APAC jurisdictions restrict the flow of funds across borders. China’s State Administration of Foreign Exchange (SAFE) requires approval for outbound remittances above certain thresholds. India’s Reserve Bank requires compliance with FEMA regulations for both inbound and outbound M&A payments. Japan’s Foreign Exchange and Foreign Trade Act requires post-transaction reporting for cross-border acquisitions. The funds flow must account for the timing and sequencing of regulatory approvals — a wire that is initiated before the necessary clearance is obtained will be blocked.

Withholding tax. Cross-border payments often trigger withholding obligations. A Hong Kong buyer acquiring an Australian target may face withholding on certain payments. The funds flow must identify the gross amount, the withholding, and the net transfer — and the buyer must remit the withheld amount to the relevant tax authority. Double tax treaties can reduce withholding rates, but the treaty benefit must be claimed in advance.

Currency conversion timing. When the purchase price is denominated in one currency but the buyer’s funds originate in another, the conversion timing and rate matter. A one-day delay in conversion on a US$50 million deal can mean a swing of several hundred thousand dollars. Sophisticated deal teams lock in rates through forward contracts or specify a conversion window in the SPA.

Multi-entity structures. Cross-border deals often involve holding companies in Singapore, Hong Kong, or other jurisdictions. The funds flow must trace the path from the ultimate source of funds through each intermediate entity to the final recipients, ensuring that each leg complies with local regulations.

Common Pitfalls and How to Avoid Them

Late preparation

The most common pitfall is starting the funds flow too late. When the memo is first circulated 48 hours before closing, there is no time to resolve discrepancies. Best practice: circulate a draft five to seven business days before closing, even if some numbers are still estimated.

Wire instruction fraud

Business email compromise targeting M&A closings is a real and growing threat. Criminals intercept email chains, impersonate parties, and substitute fraudulent wire instructions. Prevention requires out-of-band verification — confirming wire details by phone to a known number, not a number provided in the same email.

Forgetting deductions

Sellers frequently underestimate the gap between headline price and net proceeds. The funds flow must include every deduction: existing debt payoff, transaction expenses, escrow, holdbacks, estimated working capital adjustment, and tax withholding. Presenting the full waterfall early — ideally before signing — avoids closing-day disputes.

Sequencing errors

In leveraged transactions, lenders may require that their funds are the last to flow (or the first), with specific conditions precedent satisfied before they release capital. If the funds flow sequence does not match the credit agreement requirements, the lender may refuse to fund — and the closing stalls.

Ignoring time zones

In cross-border APAC transactions, closing parties may be in Tokyo, Singapore, Sydney, and New York. Wire transfer cut-off times vary by bank and jurisdiction. A wire initiated at 4 PM Singapore time may not settle in New York until the next business day. The funds flow schedule must account for time zones and bank processing windows.
