Cash Sweep

A cash sweep converts cash generation into contractual deleveraging

Private-equity models often assume that free cash flow reduces debt. The actual financing documents may go further by requiring specified cash to be prepaid under an excess cash flow sweep or similar mandatory-prepayment provision.

The operative word is defined. Credit agreements do not necessarily use the same definition as accounting free cash flow.

Simplified calculation

Assume a loan requires a 50% sweep when leverage is above a threshold. If contractual excess cash flow is $30 million, a simplified calculation is:

$30M × 50% = $15M mandatory prepayment

Real agreements can permit reductions for capital expenditures, acquisitions, voluntary debt repayments and other items. They may also reduce the sweep percentage when leverage falls.

Cash sweep vs. voluntary debt paydown

A voluntary repayment is a capital-allocation choice available to the borrower, subject to loan terms. A cash sweep is a contractual requirement triggered by defined conditions.

That difference affects flexibility. Cash subject to a sweep may not be freely distributable to the sponsor even if the company would otherwise prefer to retain or deploy it.

Why lenders want sweeps

A sweep can accelerate deleveraging when the borrower performs well. It reduces lender exposure and captures some of the company’s cash generation for repayment before the cash can be used for shareholder distributions or other discretionary purposes.

Why sponsors negotiate the definition carefully

Sponsors generally want enough operating flexibility to fund growth and execute the investment plan. Negotiated features can include:

• leverage-based step-downs
• permitted deductions
• credit for voluntary prepayments
• acquisition and capex adjustments
• thresholds and de minimis baskets.

A headline “50% sweep” therefore does not necessarily mean half of accounting free cash flow is automatically paid to lenders.

Common mistake: treating a cash sweep as a bank account transfer

In LBO analysis, the term usually describes a mandatory-prepayment mechanism, not merely moving cash between deposit accounts. The loan definition and calculation schedule control.

Investor implication

Cash sweeps can strengthen the deleveraging path assumed in a buyout model, but they also reduce discretionary cash. Analysts should model the loan’s actual definition rather than inserting a generic percentage of free cash flow.

Example

A credit agreement requires 50% of annual excess cash flow to be prepaid when net leverage exceeds a stated threshold. If defined excess cash flow is $30 million and no permitted reductions apply, the borrower may have a $15 million mandatory prepayment.

Cash sweep percentages are not comparable without reading the definition of excess cash flow and the step-down mechanics. Capital expenditures, acquisitions, voluntary prepayments and leverage ratios can materially change the amount actually swept.
