BOC Aviation Limited (2588.HK): Mission and Values

• Aircraft acquisition: BOC Aviation acquires aircraft through direct purchases from manufacturers (primarily Airbus and Boeing) and via leaseback arrangements with airlines, building its owned fleet and managed assets.
• Long-term leasing: The company signs long-term operating lease agreements (typically 7-12 years or longer for narrowbodies and widebodies) to provide airlines access to modern aircraft while shifting capital expenditure and residual-value risk to the lessor.
• Active portfolio management: BOC Aviation rotates its portfolio by selling older aircraft and investing in newer-generation models (A320neo family, A220, Boeing 737 MAX, A321neo, A350, 787), maintaining a young average fleet age to enhance lease desirability and maintenance economics.
• Capital raising: To fund acquisitions and operations, BOC Aviation raises capital via secured and unsecured debt (bank facilities and bond issuances), revolving credit facilities, and equity when required. The company accesses international capital markets to optimize funding costs.
• Global footprint and customer base: Headquartered in Singapore with key offices in Dublin, London, New York and Tianjin, BOC Aviation serves a diverse, global airline customer base across full-service, low-cost and start-up carriers.
• Commercial leverage: The firm leverages its investment-grade credit profile and strong balance sheet to negotiate favorable pre-delivery payment schedules, delivery slots and purchase prices with OEMs and to structure attractive lease terms with airline customers.

• Lease rentals: The primary revenue source-recurring operating lease income generated over the life of leases.
• Sale of aircraft: Disposals of older or surplus aircraft realize capital gains and refresh the fleet; structured sales (sale-and-leaseback) can also generate liquidity.
• Management and ancillary services: Fees from third-party asset management, maintenance reserves, and end-of-lease services (redelivery support, asset marketing).
• Financing spreads: Acting as a creditworthy borrower, BOC Aviation obtains competitive funding rates and lengthens debt maturities to preserve margin between lease yields and funding costs.

• Young, modern fleet strategy - focuses on fuel-efficient aircraft that are in highest demand and command premium lease rates and lower maintenance reserves.
• Diversification - lease exposure across geographies and carrier types to reduce concentration risk.
• OEM relationships - long-standing partnerships with Airbus and Boeing secure production slots, negotiated terms and flexibility on delivery timing.
• Capital market access - regular bond issuances and syndicated facilities to match long-term lease duration, managing interest-rate and refinancing risk.

• Bond issuances: Regular public and private placements in USD, EUR and HKD markets to match investor demand and currency needs.
• Syndicated bank facilities and ECA-supported loans: Long-term loans often aligned to aircraft delivery schedules.
• Commercial paper and revolving facilities: Short-term liquidity management.

• Maintenance reserves and redelivery provisions ensure lessee-funded maintenance and structured handback processes.
• Insurance and residual-value stress testing are integral to underwriting and portfolio valuations.
• Concentration limits by airline, country and aircraft type reduce single-entity or market exposure.

BOC Aviation Limited (2588.HK): How It Works

• Primary business model: purchase aircraft and lease them to airlines under medium‑ to long‑term operating leases (typically 5-12 years initial terms, often with extensions).
• Capital structure: funds aircraft acquisitions via a mix of bank debt, export finance, securitisations, unsecured bonds and equity; access to diversified funding reduces cost of capital.
• Fleet strategy: focus on young, fuel‑efficient narrowbody and widebody types (e.g., A320 family, B737 family, A350, B787) to maximize lease rates, remarketing value and residual values.
• Risk management: diversified airline customer base, staged lease maturities, residual value modelling, and active currency/interest rate hedging.

• Lease rental income - Core recurring revenue derived from operating leases and finance leases; rentals are typically paid monthly over the lease term and indexed or denominated in USD or other major currencies.
• Aircraft sales - Realisation of capital gains (or crystallisation of losses) through sale of owned aircraft into the secondary market or to airlines; sales are opportunistic and timing-dependent on market demand and aircraft age.
• Interest income on financing - Earnings from capital finance packages (loan financing, sale‑and‑leaseback arrangements or direct financing) provided to airline customers, generating interest spread over funding costs.
• Third‑party management and fees - Management fees and incentive fees from running portfolios for institutional investors and funds (aircraft asset management, lease placement, remarketing).
• Ancillary services - Revenue from maintenance reserves, technical management, redelivery services, and other commercial or technical services charged to lessees or third parties.
• Currency and balance sheet management - Benefits from favourable currency exposures and active treasury management that enhance net income when FX and interest rate movements align with positions.

• Fleet size (owned and managed): 570+ aircraft across owned, managed and on‑order positions.
• Geographic diversification: customers in 30+ countries; no single region dominates >40% of portfolio risk.
• Lease portfolio average remaining lease term: typically mid‑single to low‑double digit years depending on portfolio vintage.
• Funding mix: combination of unsecured bonds, bank loans, export credit, and ABS/securitisations; investment grade access supports lower funding costs relative to smaller lessors.

• Operating lease: BOC Aviation buys a new A320neo for USD 60-70m list; leases to an airline at an annual rental that covers financing costs, depreciation assumptions and expected margin over the lease term.
• Sale and leaseback: Airline sells an owned aircraft to BOC Aviation, which pays cash to the airline and leases the aircraft back under a long‑term lease-immediately generating lease income and freeing airline capital.
• Managed portfolio: Third‑party investor appoints BOC Aviation to source, lease and remarket aircraft; BOC earns management fees plus potential performance incentives.

• Upcycle: Strong airline demand → higher lease rates and faster disposal values → increased income from both rentals and aircraft sales.
• Downcycle: Soft demand → pressure on lease renewals and sale prices; emphasis shifts to remarketing, lease restructuring and opportunistic financing.
