BOC Aviation Additional Discussion Report: SSC Discussion Follow-up Monitoring Items

1. Purpose and Treatment

This report is a supplementary report that organises additional discussion points on BOC Aviation Limited raised in the discussion, based on the existing issuer_summary. The discussion distinguishes among claims made in the discussion, context already confirmed in the existing report, and unverified items that should be checked going forward. Because this preparation process did not include additional web verification or re-checking of primary sources, external articles, rating actions, and individual contract examples mentioned in the discussion are treated as candidates for continued follow-up and are not fixed as newly verified facts.

The context already confirmed in the existing issuer_summary is that BOC Aviation has a young aircraft portfolio, 100% utilisation, a long average remaining lease term, a relationship with the Bank of China group, and substantial committed liquidity, while its main credit constraints are its 337-aircraft orderbook, US$19.1bn of committed capital expenditure, gross debt to equity of 2.5x, airline credit risk, aircraft values, and the legal limits of parent support.

2. Read-through from the Discussion

The core point in the discussion was to frame BOC Aviation’s downside not as a standalone shock to aviation demand, but as a case in which multiple credit channels deteriorate at the same time. If PDPs and delivery payments linked to the orderbook coincide with deterioration in the US dollar funding market, the key issue becomes not only existing liquidity and operating cash flow, but the extent to which the company relies on third-party banks, the bond market, aircraft sales, and the Bank of China group RCF to maintain funding.

At the same time, on the asset side, 100% utilisation and long-term lease contracts do not eliminate airline credit risk. Before utilisation declines or large impairments emerge, there may be increases in deferred receivables, past due receivables, lease restructuring, use of security deposits, reliance on maintenance reserves, early termination, or repossession.

Bank of China group support can currently be treated as a clear credit enhancement, but it is not the same as an explicit guarantee of individual debt obligations. The discussion presented the hypothesis that the risk is less that support suddenly disappears, and more that a shift to filling reduced third-party market access with BOC-related funding would become a dividing line for spreads and rating assessment.

On financial policy, it is reasonable to view BOC Aviation as a “balanced” operator that continues growth investment while remaining mindful of maintaining its A- rating. However, given strong aircraft demand, there is scope for the company to continue large orders and asset growth. It therefore remains unverified in what order the company would adjust new orders, delivery and PDP burdens, aircraft sales, dividends, undrawn credit facilities, and leverage management under stress.

Finally, on the fleet side, concentration in the A320NEO family and Boeing 737-8/9 is a strength in normal conditions. However, the discussion concluded that unless the engine mix, GTF-related groundings, spare engine availability, manufacturer compensation, and 737 delivery delays are understood, there is a risk of overstating the strength of a “young narrowbody-focused” portfolio.

3. Summary of Q&A Content

3.1 Stress from the Overlap of the Orderbook and US Dollar Funding Markets

The purpose of the first question was to examine whether BOC Aviation’s largest downside is not a temporary deterioration in airline demand in isolation, but a case in which 2026-2028 deliveries, PDPs, and debt maturities coincide with deterioration in the US dollar funding market, while the company carries a 337-aircraft orderbook and US$19.1bn of committed capital expenditure.

The response indicated that, based on existing disclosures, an immediate liquidity shortfall structure has not been confirmed. The existing issuer_summary also states that, as of end-2025, BOC Aviation had US$6.9bn of liquidity, around US$2.2bn of operating cash flow after interest payments, the Bank of China group RCF, and access to the bank and bond markets. At the same time, the discussion highlighted stress sensitivity: because capital expenditure and debt maturities overlap in 2026-2028, headroom is not abundant under a full no-funding and no-asset-sale assumption.

The follow-up discussion concluded that the analysis should not simply look at “undrawn committed facilities plus operating cash flow”, but should assess how the quality of funding sources deteriorates. It is necessary to distinguish among stages: a stage in which bonds and third-party bank loans can be used in combination as usual; a stage in which bond tenor, pricing, and issuance volume deteriorate; a stage in which reliance on third-party bank loans and aircraft sales increases; and, finally, a stage in which reliance on the BOC group RCF increases.

The credit implication is that the quality and replenishment capacity of funding sources are the early warning lines, more than the total amount of liquidity. As long as the BOC group RCF is maintained as a backup, it is a clear support factor. However, if it shifts into a permanent funding source that cannot be replaced by third-party banks or the bond market, that could indicate weaker issuer-level funding strength even if liquidity remains available.

3.2 Airline Credit Risk and Signals Earlier than Utilisation

The second major question was whether 100% utilisation and long-term lease contracts are sufficient to contain credit risk to airlines. The PM sought to confirm whether, in a scenario combining recession, high fuel prices, high interest rates, and geopolitical risk, the asset side could weaken cash flow and leverage metrics through delayed lease collections, renegotiation of terms, aircraft returns and transition costs, and declines in aircraft values.

The response stated that 100% utilisation and a young narrowbody-focused portfolio are important defensive factors, but utilisation can be a lagging indicator. Deterioration in airline credit could first appear as weaker collection terms, such as payment deferrals, rent holidays, lease restructuring, deferred receivables, past due receivables, ECL allowance, and use of security deposits. Early termination, repossession, transition costs, and lower utilisation are heavier indicators, but they were organised as indicators that would appear later.

The discussion discussed trade receivables, deferred receivables, past due ageing, maintenance reserves, security deposits, and the Stage classification of finance lease receivables as of end-2025. However, because these details were not re-verified against primary sources in this report preparation process, the notes to the annual report need to be re-checked in the next update.

The credit implication is that airline credit risk should not be assessed only by asking whether aircraft are off lease. For BOC Aviation, even while lease contracts remain in place and aircraft are operating, payment-term concessions and consumption of collection buffers may progress first. If this coincides with deterioration in the asset-sale market or funding market, the perception of the liquidity buffer discussed in Question 1 will also change.

3.3 Incorporation and Limits of Bank of China Group Support

The third discussion point was how far Bank of China group support should be incorporated into the credit assessment. The PM noted that the BOC group RCF, the relationship with the parent, and confidence in the banking market are strong support factors, but sought to confirm how the market would draw the line around support under stress, given that there is no explicit guarantee of individual debt obligations.

The response concluded that BOC group support is quite important for credit assessment, but the scope that can be incorporated is mainly liquidity support, supplementation of market access, and maintenance of banking syndicate confidence. Capital injection, absorption of large losses, guarantees of all debt, and unconditional support to defend ratings should not be treated as the base case.

The follow-up discussion addressed specific triggers that could weaken the support assumption. Rather than an increase in RCF usage by itself, the important indicators were deemed to be a decline in third-party bank participation, shorter club loan tenors, collateral requirements, fewer participating banks, concentration of funding in BOC-related banks, permanent use of the BOC group RCF, and rating agency indications of a review of support uplift or parent support assessment. The quality of third-party market access is the earliest observable indicator, while rating agency commentary is the heaviest confirmation signal.

The credit implication is that it would be inappropriate either to treat BOC support as zero or to treat the debt as equivalent to explicitly guaranteed debt. The correct positioning is that BOC Aviation is an aircraft leasing company whose liquidity and market access are supplemented by parent support, while the debtor remains BOC Aviation.

3.4 Growth Investment, A- Rating Maintenance, and Financial Defence Measures

The fourth discussion point was whether BOC Aviation’s financial policy is conservative management that clearly prioritises maintaining its A- rating, or whether there is scope for it to pursue growth opportunities even with higher leverage during a period of strong aircraft demand. The PM sought to confirm which items should be viewed as defensive lines: orderbook execution, PDPs, aircraft sales, dividends, leverage, and undrawn committed facilities.

The response characterised BOC Aviation as a balanced operator that actively pursues orderbook execution, PDPs, and aircraft acquisitions within a range that allows it to maintain its A- rating and market access. The existing issuer_summary also describes the company as an issuer that supports high-quality aircraft assets and long-term leases with high but managed leverage and substantial liquidity. In other words, this is not a low-risk static credit, but an aviation finance credit that continues to invest for growth.

The follow-up discussion addressed the financial defence measures that would be used first under stress. Because the company has not explicitly disclosed the order of its defensive measures, the discussion hypothesis organised them in the following order: curbing new orders, adjusting the pace of deliveries and PDPs, increasing aircraft sales, restraining dividends, preserving undrawn credit facilities, and tightening leverage limits. Curbing new orders is the easiest measure to use early, but it does not reduce PDPs or delivery obligations under the existing orderbook. Aircraft sales are effective as portfolio recycling in normal conditions, but under stress they may also signal lower gains on sale or declining asset values. Dividend restraint becomes important less for its monetary effect and more as a signal of rating-defence posture.

The credit implication is that the analysis should look not only at the current gross debt to equity ratio, but also at whether the company continues large new orders during a period of strong growth opportunities, and whether it adjusts order, dividend, and aircraft-sale policies early under stress. If large new orders continue, undrawn credit facilities decline, gains on sale narrow, and leverage moves toward 3x while dividends are maintained, the company may have tilted toward prioritising growth over defending its A- rating.

3.5 New-generation Narrowbody Concentration, Engines, and Delivery Delays

The final discussion point was how to assess concentration in the A320NEO family and Boeing 737-8/9. The PM sought to confirm the extent to which overlapping manufacturer delivery delays, engine issues, operating restrictions on specific aircraft types, and residual value reassessment could affect the growth plan, lease revenue, and scope for aircraft sales.

The response concluded that concentration in the A320NEO family and 737-8/9 is normally a strength in terms of remarketing capacity, demand, and residual value, but aircraft type names alone are too broad for risk assessment. Within the A320NEO family, Pratt & Whitney GTF-powered aircraft and CFM LEAP-powered aircraft may differ in terms of grounding risk, maintenance burden, spare engines, manufacturer compensation, and sensitivity of residual value. For the 737-8/9, the main issue may not be demand itself, but Boeing-side production, quality, and delivery constraints that affect the timing of lease commencement and revenue generation.

The follow-up discussion identified the most important items to confirm: the engine-by-engine breakdown of the A320NEO family, the share of GTF-powered aircraft, BOC Aviation-specific grounding or maintenance downtime, spare engine availability, the existence of manufacturer compensation, and the actual impact of 737-8/9 delivery delays on lease commencement timing. The discussion mentioned individual lease examples involving LEAP-powered and GTF-powered aircraft, as well as reports on Boeing production recovery, but these were not re-checked against primary sources in this report preparation process.

The credit implication is that the 337-aircraft orderbook should not simply be treated as “future revenue”, but as an asset pipeline involving deliverability, engine reliability, lease commencement timing, ability to supply customers, aircraft-sale margins, and residual value. If differences in sale margins by aircraft type and engine widen, that would also affect financial defence capacity through aircraft sales.
