Incremental facilities and MFN protection

Incremental capacity is often the path of least resistance for new senior money. The borrower can add commitments under an existing framework, use an incremental equivalent debt provision or place a separate instrument that relies on the same capacity. The process may avoid a full refinancing and, depending on the documents, may require consent only from the new lenders and the administrative agent.

The headline incremental amount rarely answers the important question. Capacity usually consists of several components with different conditions. A borrower may combine free-and-clear capacity with ratio-based capacity, reclassify debt between components and obtain acquisition-related relief from testing requirements. The analysis therefore turns on how the components interact, not simply whether an incremental facility provision exists.

MFN protection addresses one consequence of that flexibility. Existing term lenders may accept a lower yield on the assumption that materially higher-priced pari passu term debt issued soon afterwards will produce a pricing adjustment. Whether that protection has substance depends on four points: which debt is covered, how yield is compared, how long the protection lasts and which transactions are excluded.

How is incremental capacity constructed?

The core architecture generally has two limbs:

The free-and-clear component is commonly a fixed amount, a percentage of EBITDA or the greater of the two. The last formulation is a grower. It preserves a minimum dollar amount while allowing capacity to expand as the borrower’s reported or covenant EBITDA increases.

That feature matters because EBITDA itself is negotiated. Acquisition adjustments, cost savings, synergies and other add-backs can increase both the denominator in a leverage test and a basket expressed as a percentage of EBITDA. A single adjustment may therefore create capacity through more than one route.

Ratio-based capacity is not necessarily a single unlimited basket. The applicable test may depend on lien priority. Pari passu secured debt might be tested against a first-lien or secured leverage ratio, junior-lien debt against another secured leverage test, and unsecured debt against total leverage or a fixed-charge coverage ratio. The definitions and debt-incurrence provisions must be read together.

What conditions apply to an incremental facility?

Availability is usually subject to conditions that extend beyond capacity. Common conditions include:

• no specified default or event of default;
• delivery of an incremental amendment or joinder;
• compliance with agreed maturity and weighted-average-life limitations;
• permitted borrower, guarantor, collateral and ranking terms;
• pro forma satisfaction of any applicable financial test; and
• representations appropriate to the transaction.

These conditions are often relaxed for acquisition-related facilities. Testing may occur when the acquisition agreement is signed rather than when the debt is funded. The borrower may need to satisfy only specified representations and specified defaults at closing. This limited-condition approach reduces the risk that financing becomes unavailable because the borrower’s position changes between signing and completion.

Maturity restrictions also require close attention. The provision may prevent incremental term debt from maturing earlier than the existing term loans or from having a shorter weighted average life to maturity. But exceptions may permit an agreed amount of inside-maturity debt, bridge facilities or debt incurred under a separate basket. A stated maturity limitation is only as broad as its exceptions.

The incremental clause may also regulate substantive terms. It might require pari passu incremental loans to share collateral and guarantees with the existing facilities, while allowing junior-lien or unsecured incremental equivalent debt under separate documentation. Other terms may be permitted if they are not materially more favourable to the new lenders, taken as a whole, subject to exceptions for terms that apply only after the existing facility matures.

Why is the free-and-clear amount often a grower?

A static basket loses relative value as a business expands. Expressing free-and-clear capacity as the greater of a fixed amount and a percentage of EBITDA prevents immediate shrinkage below the negotiated floor while allowing capacity to scale with the enterprise.

The formulation also transfers risk to lenders. EBITDA may grow through operating performance, acquisitions or contractual adjustments rather than cash earnings alone. If the agreement measures the grower using covenant EBITDA after giving pro forma effect to a transaction, an acquisition can increase incremental capacity at the moment the borrower needs financing.

The measurement date is therefore material. Questions include whether EBITDA is measured at incurrence, commitment, signing or funding; whether unused commitments consume capacity; and whether later EBITDA declines reduce previously established availability. Some agreements preserve capacity established when commitments are obtained, even if the facility is drawn later.

Currency mechanics can matter as well. A basket may be established in one currency while incremental debt is issued in another. Exchange-rate provisions may protect an incurrence from becoming non-compliant solely because currencies move after the relevant date.

How does ratio-based incremental capacity operate?

Ratio-based capacity is frequently described as unlimited, but that is only shorthand. It is limited by the borrower’s ability to satisfy the relevant ratio on a pro forma basis.

The calculation may give effect to the incremental debt, the use of proceeds and the related transaction. Debt used to refinance existing borrowings may have a limited net effect. Debt funding an acquisition may be tested with acquired EBITDA and permitted synergies included. Revolving commitments present a separate question: the agreement may test the entire commitment, only amounts drawn or an assumed drawing level.

Cash netting can materially change the result. Some agreements calculate leverage after netting unrestricted cash, potentially including proceeds of the new debt before they are applied. Others restrict the amount or type of cash that can be netted. The analyst should reconstruct the precise numerator rather than relying on a reported leverage figure.

Another issue is ordering. If the borrower incurs debt using both ratio-based and free-and-clear capacity, the agreement may deem the ratio debt incurred first. That sequencing can preserve the fixed basket because adding free-and-clear debt to the ratio calculation might otherwise reduce ratio capacity.

Reclassification provisions create further flexibility. Debt initially incurred under the free-and-clear basket may later be deemed or elected to use ratio capacity once performance improves. The released fixed capacity can then be used again. The document should be checked for automatic reclassification, elective reclassification and prohibitions on double counting.

What does MFN protection actually do?

An MFN clause generally protects an existing term tranche when specified new term debt is issued above a permitted yield differential. If the all-in yield on the covered new debt exceeds the existing tranche’s all-in yield by more than the agreed threshold, the pricing on the existing tranche increases so that the differential does not exceed that threshold.

The protected amount is therefore not necessarily a full match. If the permitted differential is 50 basis points, for example, the existing yield is adjusted only to the level required to leave that difference. The actual threshold must be taken from the agreement.

The comparison commonly extends beyond the stated margin. “All-in yield” may include:

• interest-rate margins;
• benchmark floors;
• original issue discount;
• upfront fees paid generally to the new lenders; and
• sometimes other economic terms treated as yield.

OID and upfront fees are often converted into an annualised amount over a specified assumed life. Arrangement, structuring and similar fees paid for services may be excluded. Floor value may count only to the extent the relevant benchmark is below the floor. These mechanics can determine whether the trigger is reached even when the headline spreads appear close.

The remedy also varies. An excess yield attributable to margin may require a margin increase. A higher floor may be addressed through an increased floor, an increased margin or a combination specified by the drafting. Analysts should not assume that every source of new-lender economics produces the same adjustment.

Which limitations most often weaken the MFN?

The sunset is the clearest limitation. MFN protection may apply only to debt incurred within a defined period after closing. Once that period expires, otherwise identical incremental debt can be issued without repricing the original tranche.

The second limitation is scope. The clause may apply only to broadly syndicated, pari passu, dollar-denominated term loans. Debt may escape because it is:

• issued under free-and-clear or ratio-based capacity excluded from MFN;
• denominated in another currency;
• unsecured or junior lien;
• structured as notes, a bridge or another non-loan instrument;
• incurred for an acquisition, investment or similar transaction;
• placed privately rather than syndicated;
• longer-dated than the protected loans; or
• incurred by a foreign subsidiary or another permitted borrower.

Some exclusions are cumulative. A provision may exclude acquisition debt, a specified amount of debt and all debt incurred after the sunset. The practical protected universe can be much narrower than the incremental debt universe.

Purpose-based exclusions deserve scepticism because proceeds are fungible. The drafting may focus on whether debt is incurred “in connection with” an acquisition rather than whether every dollar is paid to the seller. The transaction steps and funds flow may therefore affect MFN treatment.

How should practitioners analyse the provision?

Start by building a capacity map. Separate fixed, grower and ratio capacity. Identify the test, measurement date, ordering rule and reclassification treatment for each component. Then map the forms of debt that can use that capacity: incremental loans, incremental equivalent debt, acquisition facilities and separate ratio debt baskets.

Next, build the MFN perimeter. Identify the protected tranche, covered new debt, permitted yield differential, sunset and every exclusion. Recalculate all-in yield using the agreement’s own conventions, including floors, OID and fees. Finally, test plausible structures rather than only the most obvious pari passu incremental loan.

The decisive question is not whether the agreement contains an MFN. It is whether the contemplated new money falls inside that MFN at the relevant time. A short protection period, narrow instrument definition and broad exclusions can leave existing lenders with little practical pricing protection even though the clause appears prominently in the incremental facility section.
