'In June 2015, an agreement to build two additional lines was signed between Gazprom, Royal Dutch Shell, E.ON, OMV, and Engie.[79] As the creation of a joint venture was blocked by Poland, on 24 April 2017, Uniper, Wintershall, Engie, OMV and Royal Dutch Shell signed a financing agreement with Nord Stream 2 AG, a subsidiary of Gazprom responsible for the development of the Nord Stream 2 project. According to the agreement, each of five companies will provide €950 million, of which €285 million should be paid in 2017. The loan from the five companies will cover 50% of the project costs of €9.5 billion. The rest would be financed by Gazprom which remains the sole shareholder of Nord Stream 2 AG'
