Incremental Facility: a Worked Example

The room for more debt is agreed on the first day.

BY MICHAEL SHANG · SIXTEEN YEARS IN COMMERCIAL BANKING · UPDATED

// THE SHORT ANSWER

For a lender joining a leveraged loan, the incremental clause answers a question it cannot otherwise answer: how much new debt could share its security and rank with it next year, without its vote. The answer is written as a formula, typically a set amount that needs no test and a further amount limited by a leverage ratio, so the room grows as earnings grow. No lender is bound to provide the new money. What the existing lenders do get is a limit on how much more richly it may be priced than their own loan, and the reading lies in what that limit leaves out.

The market is mid-market commercial lending as practised in New Zealand and Australia; where a convention differs elsewhere, the page says so.

// 01 — WHAT THE CLAUSE LETS A BORROWER ADD

A sponsor-owned group that buys businesses for a living cannot know at signing how much it will need to borrow, or when. Without an incremental clause, each new loan would mean an amendment to the agreement, a vote of the lender group, and a negotiation over whether the new money may share the security. With one, the borrower can add new term loans, or new revolving commitments, under the same document and the same guarantees, from existing lenders or new ones, in a matter of weeks.

For the lenders already in the loan, the clause is a pre-agreed dilution. Debt added under it commonly ranks equally with theirs against the same assets, and new lenders join the vote. That is why the clause is negotiated as hard as the margin. It belongs mainly to leveraged and sponsor-backed lending. In bank-led mid-market lending, the same need is often met by an accordion, or simply by a request to the bank.

// 02 — HOW THE CAPACITY IS MEASURED

Fixed amount = a stated sum, or the greater of a sum and a share of EBITDA
Ratio amount = any further debt that keeps pro forma leverage ≤ the stated ratio
Prepaid amount = in some agreements, term debt the borrower has voluntarily repaid
Capacity = the three together, less what has already been used

The ratio amount is the one that grows. It is tested on pro forma EBITDA, so the definition of earnings, and how much expected savings it lets in, decides the room as much as the ratio does. Agreements also say which leverage applies: first-lien leverage for debt that will share the first-ranking security, a total or secured measure for debt that will rank behind it. Many agreements test the ratio leaving out any fixed-amount debt raised on the same day, and let the borrower later reclassify fixed-amount debt as ratio debt once earnings allow, which refills the fixed amount.

The price protection is usually called a most-favoured-nation clause. It compares yields rather than margins: the margin, any interest-rate floor, and any discount or upfront fee shared with the lenders, spread over an assumed life the agreement sets. If the new term debt yields more than the existing loan by more than an agreed cushion, the existing margin rises until the gap equals the cushion. The clause may lapse after a period, and may exclude debt raised under the fixed amount, debt for acquisitions, debt that matures well after the existing loan, or debt that is not a syndicated term loan.

// 03 — THE EXAMPLE

A sponsor-backed insurance-broking group, constructed for this page like every figure on it, has a US$240m first-lien term loan at a margin of 4.50%, cash of US$20m and EBITDA, as its agreement defines it, of US$60m. Its incremental clause allows a fixed amount of the greater of US$30m and 40% of EBITDA, plus any amount that keeps first-lien net leverage at or below 4.00 times. It agrees to buy a rival broker earning US$10m for US$75m, funded entirely with incremental debt. The levels are the example's, not a market norm.

Net debt today 240 − 20 = 220
Leverage today 220 ÷ 60 = 3.67×
Pro forma EBITDA 60 + 10 = 70
Net debt allowed 4.00 × 70 = 280
Ratio amount 280 − 220 = 60
Fixed amount greater of 30 and 24 = 30
Capacity on the day 60 + 30 = 90

The group borrows US$75m: US$60m under the ratio and US$15m under the fixed amount. Net debt becomes US$295m and leverage 4.21 times (295 ÷ 70), above the 4.00 ratio, and permitted, because the fixed amount was not tested against it. The ratio in the clause is a test for one part of the capacity, not a ceiling on leverage.

The new loan is priced at a margin of 4.75% and issued at 98, a two-point discount. Spread over the four-year life this agreement assumes, the discount is worth 0.50% a year. The cushion is 0.50%.

Yield on the new loan 4.75 + (2 ÷ 4) = 5.25%
Yield on the existing loan 4.50 + 0 = 4.50%
Gap 5.25 − 4.50 = 0.75%
Above the cushion 0.75 − 0.50 = 0.25%
Existing margin becomes 4.50 + 0.25 = 4.75%
Cost to the borrower 240 × 0.25% = US$0.6m a year

Had the clause excluded debt raised for acquisitions, or lapsed twelve months after signing, the existing lenders would hold a loan yielding 0.75% less than the debt now ranking beside it, with no step-up at all.

// 04 — HOW IT DIFFERS FROM AN ACCORDION

Both let a borrower add debt under an agreement it has already signed, and in neither is the new money committed. The difference is in what can be added. A mid-market accordion often enlarges an existing facility on its existing terms, up to a fixed sum, subject to a leverage test on the day. An incremental clause can create new tranches with their own margin, maturity and amortisation, within limits such as a maturity no earlier than the existing term loan, with capacity that grows with earnings.

That freedom is why fungibility matters. A new term loan written on identical terms to the old one becomes a fungible term loan, one class that votes and trades together; one that differs on any term becomes a separate tranche. Debt raised outside the agreement altogether, under the debt covenant's permitted baskets, may escape the price protection entirely unless the document carries it across.

// 05 — WHERE IT DECIDES A FILE

A lender reading a leveraged loan at signing can test the credit at full capacity as well as at opening leverage: if every dollar of the fixed and ratio amounts were borrowed against today's earnings, what would leverage and interest cover be, and what would the security cover? In the example, with no acquisition the capacity on today's earnings is US$50m (US$20m under the ratio and the US$30m fixed amount), which would take leverage from 3.67 to 4.50 times (270 ÷ 60) with nothing new to show for it.

The second reading is the protection. A cushion of 0.50% means little if acquisition debt is carved out and the group is an acquirer. The third is the earnings definition, because every allowance for expected savings becomes debt capacity at the stated multiple. When a request arrives later, each lender's decision to take part is a fresh credit decision on a larger business.

// QUESTIONS PEOPLE ASK

What is MFN protection in a term loan?
It is a clause that protects existing term lenders when the borrower later raises new term debt that ranks equally with theirs. If the new debt's yield, counting margin, floors and any discount or shared fees, exceeds the existing loan's by more than an agreed cushion, the existing margin rises to close the gap to the cushion. Its value depends on its limits: a sunset, or exclusions for acquisition debt or debt raised under a fixed amount, can leave the lenders unprotected exactly when new debt is raised.
What does free and clear mean in an incremental facility?
It is the fixed part of the capacity, available whatever the borrower's leverage. It may be a stated sum or the greater of a sum and a share of EBITDA, so that it grows with the business. Because it is not tested against the ratio, debt raised under it can take leverage above the ratio level, and some agreements let the borrower reclassify it as ratio debt later, freeing the fixed amount to be used again.
Do existing lenders have to provide incremental loans?
No. An incremental clause sets the room and the terms on which new debt may be added, but each lender decides whether to take part when the borrower asks. Existing lenders may be offered the new loan first, and new lenders can join if they decline. A lender that declines still sees the debt added beside it if others provide it.
What is incremental equivalent debt?
It is debt a borrower raises outside the facility agreement, often bonds or a separate loan, that uses the same capacity the incremental clause allows. Agreements commonly let the borrower take the capacity in either form. The difference for existing lenders is in the protections: price protection, maturity limits and ranking terms written into the incremental clause may not apply to debt raised outside it unless the document carries them across.
