Debt finance

Debt portability

Check whether existing financing can remain in place through the proposed ownership change and what conditions must be satisfied.

Quick answer

Debt portability is a contractual feature that can allow debt to remain with a borrower after a qualifying change of ownership without triggering the associated mandatory repayment. Its availability depends on the agreement's conditions, including any buyer eligibility requirements. Review the exact clause before incorporating retained debt into acquisition funding.

Meaning and transaction use

Latham & Watkins' 2024 UK acquisition-finance chapter describes portability provisions allowing a sponsor sale without the usual change-of-control repayment trigger where the purchaser meets agreed criteria or is on an agreed list. This describes negotiated financing mechanics. [S1]

Proposed review method: create a conditions matrix tied to the actual debt agreement. Map the proposed buyer and ownership chain to every eligibility test, notice, deadline and financial condition. Keep an alternative closing funds flow showing debt repayment until satisfaction of the portability requirements is evidenced.

Worked example

Illustrative acquisition funding comparison only. Existing debt is USD 15 million. Assume repayment would require a 1% contractual premium and USD 200,000 of other cash financing costs. For the portability scenario, assume all relevant conditions are satisfied and no portability fee is payable.

ItemRepayment scenarioPortability assumption
Existing principalUSD 15,000,000 repaidUSD 15,000,000 retained
Repayment premiumUSD 150,000None assumed
Other cash costsUSD 200,000None assumed
Replacement cash requirementUSD 15,350,000No repayment cash assumed

The repayment scenario requires USD 15.35 million for these items. Retaining the debt leaves USD 15 million outstanding with continuing obligations. The comparison assumes portability eligibility; it does not prove that the lender documents permit the proposed acquisition.

Proposed transaction review process

Identify the trigger

Read change-of-control, mandatory-prepayment and portability provisions together.

Test the purchaser

Map the acquiring entities and ultimate ownership to the eligibility requirements.

Evidence each condition

Assign financial tests, certifications, notices and deadlines to named transaction owners.

Reconcile both funds flows

Show the closing outcome if portability is available and the funding requirement if it is unavailable.

Evidence checklist

Financing documents

Executed agreement, amendments and the relevant change-of-control definitions.

Buyer structure

Acquisition chart, ownership evidence and eligibility analysis.

Condition file

Calculations, certificates, required notices and documented consents where applicable.

Closing finance

Outstanding debt, repayment quotation, associated costs and alternative funding evidence.

Decision framework

SituationProposed action
The buyer falls outside an agreed categoryAssess consent or replacement financing before assuming portability.
A required financial test is marginalCheck definitions and test-date assumptions, then model a downside case.
A notice deadline precedes closingAssign delivery responsibility and retain evidence of timely compliance.
Retained debt limits the buyer's planReview covenants and permitted actions against the intended post-acquisition strategy.

Common errors to check

  • Assuming every ownership change qualifies.
  • Using a term-sheet summary without checking executed wording.
  • Leaving ongoing debt service outside the acquisition model.
  • Treating anticipated consent as an obtained consent.

Test the retained-debt case

Bring the financing agreement, proposed ownership chart and closing funds flow to an acquisition-finance review. Identify unsatisfied conditions and the alternative funding requirement before committing to the structure.
