Sources and Uses of Funds

Understanding Capital Structure in M&A Transactions

“
Just like how the assets side must be equal to the liabilities & equity side on the balance sheet, the sources side must be equal to the uses side
The fundamental principle of Sources and Uses tables mirrors basic accounting balance principles

Key Components of M&A Transaction Costs

Advisory Fees

Fees to bankers, lawyers and accountants, paid in cash and expensed during the year immediately after the deal. Calculated on the basis of acquisition enterprise value.

Debt Issuance Fees

Fees to debt underwriters, paid in cash and usually capitalized. These are then amortized over the term of the debt using the effective interest method.

Equity Issuance Fees

Fees to equity underwriters that are kept by underwriters post share sale. Amount paid by new equity investors as part of share consideration.

Building a Sources and Uses Table

1

Calculate Total Uses

Determine the purchase price and add all transaction fees including advisory, debt issuance, and equity issuance fees

2

Structure Debt Financing

Identify the amount and types of debt financing available for the transaction based on target company cash flows

3

Plug with Equity

The investor plugs the remaining gap between sources and uses with equity financing to balance the transaction

Capital Structure Impact on Returns

The proposed capital structure is among the most important return drivers in an M&A transaction. The right balance of debt and equity can significantly impact investor returns and risk profile.

Sources and Uses Table Validation Checklist

The Sources and Uses table serves as the financial blueprint for any M&A transaction—a critical document that maps out exactly where every dollar comes from and where it goes. Think of it as the deal's accounting equation, ensuring mathematical precision in what are often billion-dollar transactions.

At its core, the sources & uses section provides a comprehensive breakdown of the total capital required to acquire a target company under a specific transaction structure. This document becomes the foundation for deal negotiations, financing arrangements, and regulatory filings, making accuracy paramount for all parties involved.

The framework operates on two interconnected sides. The "Uses" section calculates the total capital outlay required to complete the acquisition, encompassing not just the headline purchase price but also the often-substantial transaction fees, financing costs, and working capital adjustments that can add 2-5% to the total deal value. Meanwhile, the "Sources" section details the precise funding mix—typically combining debt financing, equity contributions, and cash on hand—that will finance the transaction.

This balance is non-negotiable: just as a balance sheet must reconcile assets with liabilities and equity, the sources side must exactly equal the uses side down to the last dollar. Any discrepancy signals either a mathematical error or an incomplete financing plan, both of which can derail deal timelines and negotiations.

In practice, a comprehensive Sources and Uses table includes numerous line items that reflect the complexity of modern M&A transactions. Here's how the key advisory and financing costs typically break down:

Advisory fees

Fees to investment bankers, legal counsel, and accountants, typically paid in cash at closing and expensed in the transaction year. Usually calculated as a percentage of enterprise value, ranging from 0.5% to 2% depending on deal size and complexity

Debt issuance fees

Compensation to debt underwriters and arrangers, paid in cash at closing but typically capitalized on the balance sheet and amortized over the debt term using the effective interest method. Can range from 1-3% of total debt raised

Equity issuance fees

Underwriting fees for new equity issuances, retained by underwriters as part of the gross proceeds. These costs are borne by new equity investors as part of their total investment and typically range from 3-7% depending on offering size and market conditions

The proposed capital structure outlined in the Sources and Uses table fundamentally drives investment returns and risk allocation in any M&A transaction. Private equity sponsors and strategic acquirers spend considerable time optimizing this mix, as the debt-to-equity ratio directly impacts both potential returns and financial flexibility post-acquisition. Ultimately, equity investors serve as the "plug" in this equation—providing whatever capital remains after maximizing debt capacity and other funding sources to ensure the transaction can close successfully.
