What is an excess cash flow sweep?
An excess cash flow sweep is a mandatory prepayment provision in a credit agreement. It requires the borrower to take a defined percentage of its excess cash flow each year — the cash left after operating needs, capital spending, scheduled debt service, and permitted distributions — and use it to pay down the loan ahead of schedule.
The point is forced deleveraging. Lenders to a leveraged borrower want the balance coming down faster than the contractual amortization curve, especially when the company is performing well and generating surplus cash. The sweep captures that upside for debt repayment rather than letting it accumulate or leak out to equity.
Crucially, the sweep is not a fixed dollar amount. It is a formula tied to actual performance: strong years sweep more, weak years sweep little or nothing. That makes it self-adjusting in a way scheduled amortization is not.
How the sweep works
The credit agreement defines both the cash flow measure and the percentage that must be swept.
- Compute excess cash flow. Start from EBITDA or cash flow from operations, then subtract cash interest, taxes, scheduled debt amortization, capital expenditures, and other permitted deductions defined in the agreement.
- Apply the sweep percentage. A common structure starts at 50% of excess cash flow, with step-downs to 25% and then 0% as the leverage ratio falls below defined thresholds. The better the credit deleverages, the less it has to sweep.
- Credit voluntary prepayments. Optional paydowns made during the year typically reduce the required sweep, dollar for dollar, so the borrower is not penalized for prepaying early.
- Apply the proceeds. The swept amount prepays the loan, usually applied to the term loan and often to remaining amortization installments in reverse order.
Why borrowers and lenders negotiate it hard
For the sponsor, the sweep competes directly with dividends, acquisitions, and reinvestment. Every dollar swept is a dollar that cannot fund growth or return to the fund, so sponsors push for lower starting percentages, generous leverage-based step-downs, and wide definitions of permitted deductions that shrink the excess cash flow figure.
For lenders, the sweep is downside protection that costs the borrower nothing in a bad year. In looser, covenant-lite markets, starting percentages have drifted down and step-downs have become more generous — but the sweep remains a standard feature of leveraged credit agreements precisely because it ties deleveraging to realized performance.
