Tangguh LNG: The umbrella deal

The financing of the $6.5 billion Tangguh liquefied natural gas (LNG) is the largest private sector investment in Indonesia's energy sector since the Asian financial crisis and brought together several funding sources, with various guarantee schemes, under one project umbrella.

When the project begins production in 2008, Tangguh will become the third major LNG facility in Indonesia. The partners in the Tangguh LNG project are: BP (37.16%), CNOOC (16.96%), MI Berau B.V. (a joint venture between Mitsubishi and INPEX, 16.3%), Nippon Oil Exploration (Berau) Ltd (a joint venture between Nippon Oil Exploration and JOGMEC, (12.23%), KG Berau/KG Wiriagar (a joint venture between Kanematsu, JOGMEC and Mitsui, 10%), and LNG Japan Corporation (a joint venture between Sumitomo and Sojitz, 7.35%).

Three separate facilities were signed on the 31 July between Tangguh, Japan Bank for International Cooperation (JBIC), Asian Development Bank, and a consortium of international commercial lenders (the JBIC and ADB loans are both bilateral, and are also guaranteed by BP and CNOOC). A further $884 million tranche from Chinese banks is still under discussion but is expected to be disbursed in April this year as construction on the plant nears completion.

Bringing Indonesia's largest ever debt deal to financial close was never going to be a simple task, and the signing of facilities worth a total of $2.6 billion is a credit to the arrangers, sponsors and development banks involved.

The debt financing includes a $1.065 billion secured commercial loan signed with Bank of Tokyo-Mitsubishi, BNP Paribas, Fortis Bank, ING, Mizuho, Standard Chartered and Sumitomo Mitsui Banking Corp.

This commercial tranche was launched into syndication in the first week of September 2006. The interest margin on the 15-year loan, which involved an Indonesian trustee borrowing structure, is 22.4bp over Libor – much lower than is typical for a long-term project financing. This is explained by the presence of an unconditional guarantee, which allows the sponsors to benefit from much tighter pricing.

According to the mandated lead arrangers the tight pricing reflected the guarantees provided by BP and China National Offshore Oil Corp (CNOOC), the state-owned oil company. Although the project is located in Indonesia, BP North America is covering 58% of the deal, mitigating lenders' exposure to Indonesian risk. CNOOC is guaranteeing the remaining 42% of the facility. There is also a put option on 31 January 2014, and the arrangers marketed the facility as having an average life of 6.94 years. Lenders were invited to join with commitments of between $30 million and $100 million and will earn participation fees of 20bp to 28bp.

There were some suggestions that a guarantee was only included after commercial lenders expressed their reluctance to fund the project on a non-recourse basis. But according to bankers the main hurdles in structuring the loan were caused by changes to the law governing Indonesia's oil and gas sector, which complicated negotiations in the early days of the project.

Indonesia amended its oil and gas law in October 2001, removing state-owned Pertamina's monopoly over the sector and establishing new agencies to issue and regulate oil and gas concessions. BP Indonesia operates Tangguh under a production sharing contract with BP Migas (no relation to BP), which replaced Pertamina as the regulatory body for upstream activities.

Tangguh is the first LNG deal to be completed since the new law was implemented and therefore carves out a precedent for future investment in Indonesia's oil and gas sector.

It is also only the second successful gas project in the country since the Asian financial crisis, following the Bontang LNG Reliability Enhancement (BLRE) project, which added a ninth train to the Badak LNG plant in Kalimantan – already the world's largest LNG facility.

JBIC's $1.2 billion commitment reflects the importance of the project to Japan, as the country looks to secure long-term energy resources for growth. BP may be the largest single stakeholder in Tangguh, but Japanese companies together account for 45.88% of the equity interest in Tangguh. Japan already buys more LNG from Indonesia than from any other country.

The ADB has committed $350 million in a private sector loan – the bank's first for an Indonesian oil and gas project. Only the Chinese debt portion remains outstanding, which will be secured on offtake contracts between Tangguh and the Fujian LNG terminal in China.

As long ago as 2002, Tangguh signed an agreement to supply 2.6 million tonnes per year to the Fujian plant for a period of 25 years. That agreement is being fine-tuned. While lenders will have no recourse to the sponsors, the Chinese receiving terminal is being developed by CNOOC and the offtake risk will be closely linked to the Chinese company.

China began construction of the facility last year and intends to use the gas to supply two new 1,800MW power plants, as well as the cities of Fuzhou, Xiamen, Quanzhou, Zhangzhou and Putian.

The Chinese non-recourse tranche is expected to be underwritten and funded by five of China's largest banks. Agricultural Bank of China, China Construction Bank, China Development Bank, Export-Import Bank of China, and Industrial and Commercial Bank of China first expressed their interest in April 2005 and were originally expected to underwrite $1.3 billion, but the sizes of the commercial tranches were altered once JBIC and ADB's commitments became clear.
