The Japan Bank for International Co-operation acted as the major creditor by financing $3.7 billion. The rest of the financing was provided by a consortium of Japanese and West European commercial banks.
The structure and amount of the project financing for the Sakhalin-II project investment program had been preliminarily agreed upon in the course of the talks with creditor banks in mid-2006. The total amount of the financing was identified to be $6.7 billion.
Gazprom holds a 50% plus one share stake in the Sakhalin-II development, while Royal Dutch Shell owns 27.5%, Mitsui holds 12.5% and Mitsubishi accounts for a 10% stake.
