JOLCO Structure in Aircraft Finance: Risk Lessons from VietJet

Updated: 22 October 2026 · IVLF Advisors

When an airline signs a Japanese operating lease with call option, it rarely focuses on what happens if rent stops. Yet the JOLCO structure spreads rights across investors, banks, a special purpose vehicle (SPV) and a security trustee, and a default sets off consequences along every link of that chain.

The recent English litigation between FW Aviation (Holdings) 1 Ltd and VietJet, which concerns four Airbus A321 aircraft financed in 2018 and 2019, has made this practical for airlines, lessors, lenders and investors in Vietnam and the wider region. This article explains how the structure works, where the risk sits, and what the dispute shows about it.

What the JOLCO structure is and why airlines use it

JOLCO stands for Japanese Operating Lease with Call Option. It is an asset-finance technique in which Japanese equity investors and commercial banks together fund the purchase of an aircraft, and the airline then leases it and operates it. At the end of the term, or at set dates, the airline holds a right to buy the aircraft at a pre-agreed price.

In the VietJet case, the UK Supreme Court’s case summary records that four A321 aircraft were financed in this way in 2018 and 2019. The funding came from Japanese equity investors, referred to as the “Owners”, and loans from commercial banks, referred to as the “Lenders”. The aircraft were leased to the airline, which flew them.

For an airline, the attraction is usually economic rather than technical. In market practice, the equity investors’ tax position allows them to accept a lower return from the lease rentals, and that benefit can be passed through in pricing. The airline obtains long-tenor funding for aircraft deliveries without a single bank carrying the whole exposure.

Parties and roles in a JOLCO structure

A JOLCO structure is a layered arrangement, and each layer carries a different type of right. According to a secondary client alert from the Tokyo International Law Office dated 31 August 2026, the VietJet transaction followed a familiar pattern: each aircraft sat in a Japanese owner SPV, which head-leased it to an intermediate company owned by the airline, which in turn sub-leased it to the airline itself. That analysis is secondary, so the roles below describe the general model.

Party	Role	Typical economic interest
Japanese equity investors	Provide the equity slice through an owner SPV	Rental return plus tax benefits; residual value risk if the option is not exercised
Owner SPV	Holds legal title to the aircraft; borrows from the banks	Pass-through vehicle with limited assets other than the aircraft and the leases
Commercial bank lenders	Provide the senior debt, said by the same alert to be roughly three quarters of the funding	Loan repayments secured by the aircraft and the lease rights
Security trustee	Holds the security for the lenders and enforces it on non-payment	Acts for the lenders as a group
Intermediate lessee	Head lessee, owned by the airline, in the structure described by the alert	Passes rent through to the owner SPV
Airline	Sub-lessee and operator of the aircraft	Use of the aircraft, plus a call option to acquire it

The alert puts the split at around 25% equity and 75% bank debt, with purchase options in the VietJet transaction totalling about US$96 million. Treat those figures as indicative and attributed to that alert rather than to the court.

How cash and security move through a JOLCO structure

The cash-flow logic of a JOLCO structure is straightforward. The airline pays rent. The rent flows up to the owner SPV, which uses it to service the bank loan and to pay the equity investors their return. If rent stops, the loan can no longer be serviced from its intended source.

The lenders therefore take security. As the Supreme Court summary describes it, the owners’ debts to the lenders were secured by a mortgage over the aircraft and by a transfer of debts to the security trustees, who hold the security for the lenders and may enforce it on non-payment. In the judgment of Saini J of 15 October 2026, the court explained that under the JOLCO structure the lenders were assigned the rights of the sub-lessors under the sub-lease agreements. In practice, that means the lenders can step into the lease and look to the airline directly.

Tax rationale and the call option

The tax rationale is what distinguishes the JOLCO structure from a plain bank loan. According to the Tokyo International Law Office alert, the Japanese investors’ real prize is an accelerated tax deduction. The JOLCO structure exists, in other words, to allocate that benefit efficiently, and the airline’s pricing is meant to reflect part of it.

The call option aircraft feature is the second distinguishing element. A call option gives the airline more than possession. According to the same alert, it can amount to a proprietary stake, which matters because it supports an argument that a court should grant relief from forfeiture if the lease is terminated. Whether such relief is available turns on the documents and the governing law, so the point should be treated as an issue to analyse, not an assumption.

Why the call option shapes default analysis

If an airline expects to exercise the option, the economics resemble an ownership path funded on lease terms. If it does not, the investors keep the residual value risk. This difference matters when something goes wrong, because the termination provisions must then decide who bears the loss of the aircraft and who keeps the benefit of any sale.

Security trustee arrangements and where default risk sits

A security trustee is the party that holds the lenders’ security on their behalf. Its identity and its ability to transfer or resign are central to how the structure behaves in distress. In the VietJet transaction, the banks that led the syndicates also acted as security trustees, according to the secondary alert, with a BNP Paribas-led syndicate financing two aircraft and a Natixis-led syndicate financing the other two.

Default risk in a JOLCO structure is not borne evenly. The airline carries operating and rental risk. The owner SPV carries almost none, because it is a conduit. The banks carry credit risk but are protected by the aircraft and the lease rights. The equity investors carry the residual and tax-related risk, which is why they depend on the termination sum provisions being effective.

Assignment limits and the “financial institution” restriction

One feature of the VietJet loan documents proved important. According to the Supreme Court summary, the loan agreement allowed security rights to be passed on only to “financial institutions”. A central issue in the litigation was whether the buyer of the lenders’ positions qualified, and the English courts found that it did. The High Court and the Court of Appeal read the term as capable of covering that buyer, and the Supreme Court refused permission to appeal on 30 October 2025, stating that the case did not raise a point of law of general public importance.

For anyone drafting or reviewing a JOLCO structure, the lesson is textual: a restriction on transferees is only as strong as its definition. If lenders may sell to distressed-debt investors, the airline’s counterparty may change at the moment of greatest stress.

Comparing the JOLCO structure with other aircraft finance routes

The table below compares the main routes at a high level. It reflects market practice and is not specific to any carrier or transaction.

Feature	JOLCO	Conventional bank loan	Plain operating lease
Source of funds	Japanese equity plus bank debt	Bank debt, with airline equity	Lessor’s own funds and debt
Legal title	Owner SPV	Airline	Lessor
Airline’s end-of-term right	Call option	Ownership from the outset	Usually return or renewal
Key pricing driver	Investors’ tax benefit	Credit margin	Lessor return and residual value
Lender security	Mortgage plus assigned lease rights through a security trustee	Mortgage over the aircraft	Held by the lessor’s own financiers
Complexity	High, with several documents and parties	Moderate	Lower for the airline

The complexity of the JOLCO structure is both its strength and its weakness. More parties allow a cheaper price, but they also mean more termination triggers, more assignment rights and more places where a dispute can arise.

Background: four A321 aircraft and the VietJet dispute

The dispute is a useful case study of the JOLCO structure because the court record is now extensive. The facts below are taken from the court judgments and a Vietnamese press report, and are presented as the courts have described them.

In 2021, during the pandemic, VietJet fell behind on rent. The Supreme Court summary refers to arrears of about US$8 million, whereas the airline’s audited half-year statements for 2026, as reported by the Vietnamese aviation press, describe about US$7.4 million. VietJet’s stated position, as reported there, is that it was negotiating a deferral with the banks.

In October 2021 the lenders served termination notices and sold their positions to an English company incorporated for the purpose of buying the debt. In November 2021 the security trustees resigned and purported to transfer their role. The loans and security were then assigned to FW Aviation (Holdings) 1 Ltd (“FWA”), which enforced the security and sold the four aircraft to other entities in the same group.

Correcting a common framing

Press coverage often describes the figure of about US$250 million as compensation or damages, and describes FWA as a debt collector. Neither description is accurate. According to the court, the sum is a judgment debt under final English orders. It comprises contractual termination sums, post-termination rental, indemnity sums, interest and costs. FWA is a Jersey aircraft-leasing company, controlled by a UK fund that has invested in distressed credit since 2021, and it holds the original lenders’ loan and security rights as assignee. In substance, it is a distressed-debt buyer that stepped into the lenders’ shoes.

What is final and what is still moving

It helps to separate final determinations from interim ones.

• Final: the liability judgment of 31 July 2024 (Picken J), which held that the leases were validly terminated and the assignments valid; the quantum judgment of 17 April 2025, awarding about US$182 million plus interest and costs; the Court of Appeal’s dismissal of the airline’s appeal on 24 June 2025; and the Supreme Court’s refusal of permission on 30 October 2025.
• Third trial: the judgment of 31 July 2026 (Birt J), summarised by counsel’s chambers, upheld the indemnity claims for two A321 NEO aircraft and dismissed other claims. The court ordered a further payment of about US$18.4 million, and a hearing on consequential matters is listed for 13 November 2026.
• Interim and ongoing: the worldwide freezing order granted on 15 October 2026; the court’s view, given on 30 September 2026, that a receivership order is appropriate in principle subject to proportionality and terms; and the enforcement position in other jurisdictions. In Vietnam, recognition was refused at first instance and on appeal, according to the English court’s summary.

The freezing order and any receivership are enforcement tools. They do not reopen the liability that the appeal courts have settled. The interim findings made by Saini J about the disposal of assets are findings at that stage, not final findings of wrongdoing, and the judge himself said it would not be appropriate at that hearing to conclude finally on certain disputed arrangements. VietJet’s stated position is that its financing and use of related companies were ordinary-course and driven by late aircraft deliveries and domestic credit limits, and the full judgment is available on the BAILII database.

Lessons from the JOLCO structure in aircraft finance in Vietnam

The dispute is ongoing, so nothing about the JOLCO structure here predicts an outcome. The following points are practical rather than evaluative, and they apply to Vietnamese carriers, lessors, banks and Japanese investors alike. For a deeper treatment of the case, see our timeline of the VietJet and FWA judgment, and for the contractual lessons, our analysis of JOLCO default liability.

For airlines

• Read the termination sum clauses as the real price of default. According to the secondary alert, the court rejected a penalty-clause challenge, reasoning that the sums protect legitimate interests, including the investors’ returns, and remain payable even though the aircraft were repossessed and sold. The general English test comes from Cavendish Square Holding v Makdessi [2015] UKSC 67.
• Open standstill or deferral talks early and record them in writing, since informal discussions may not suspend termination rights (VietJet says it was negotiating a deferral when termination notices were served).
• Check the return conditions and indemnity provisions, since the third trial turned on costs of restoring aircraft and exporting them.

For lessors, banks and investors

• Draft the transferee definition with care. A restriction to “financial institutions” invites argument about who qualifies.
• Understand how the security trustee can resign and be replaced, and who can then direct enforcement.
• Consider how cross-border enforcement would work in practice. According to the court, Vietnamese courts at first instance and on appeal refused to recognise the English judgments, and recovery elsewhere has faced substantial hurdles. In Singapore, an aircraft seizure order was made.

Vietnam-specific points to review

Vietnamese carriers finance fleets through leases, bank facilities and foreign investors, so the documents interact with several local regimes. These include the civil procedure rules on recognising foreign judgments, foreign-exchange controls on payments abroad, security and registration rules, and bankruptcy law. This article does not analyse those regimes, and their effect should be checked against the current text and the governing documents.

The Hanoi courts’ reasoning, as summarised by the English judge, was that allowing the lender-side party both to keep the aircraft and recover termination payments conflicted with the Vietnamese principle that damages must reflect actual loss and fairness. Foreign lenders considering Vietnamese exposure should therefore assume that an English judgment is not self-executing at home.

Conversely, Vietnamese parties should not assume that local non-recognition ends the exposure. The English orders remain final in England, and the English court has granted interim enforcement tools in aid of the judgment debt. A fuller picture appears in the UK Supreme Court case page.

Conclusion

The JOLCO structure is a sophisticated bridge between Japanese tax capacity and airline operating needs. Its price advantage depends on documents that work when rent stops, and the VietJet litigation shows how much turns on termination sums, transfer rights and enforcement routes. The sensible next step for any party is to map its own documents against those points before a default, not after.

Frequently Asked Questions

What does JOLCO stand for?

It stands for Japanese Operating Lease with Call Option. Japanese equity investors and banks fund an aircraft, the airline leases and operates it, and the airline holds an option to buy it on agreed terms.

Why do airlines choose a JOLCO instead of a bank loan?

In market practice, investors’ tax benefits can lower the airline’s financing cost and widen the funding base. The trade-off is documentary complexity, with more parties and more termination and assignment provisions to manage.

What does a security trustee do in a JOLCO?

It holds the lenders’ security, including the aircraft mortgage and assigned lease rights, and may enforce it on non-payment. It acts for the lenders as a group rather than for any single bank.

Is the US$250 million in the VietJet case compensation?

No. According to the English court, it is a judgment debt, made up of contractual termination sums, indemnities, interest and costs, owed to the assignee of the lenders’ rights. It is not a tort-style damages award.

Are the freezing order and receivership final findings?

No. They are interim enforcement measures, and the court’s findings at that stage are not final conclusions of wrongdoing. The underlying liability is final after the appeal courts and the Supreme Court’s refusal of permission.
