Representative matters

DEG, FMO, PROPARCO and CIFI on the $110 million secured credit facility made available to Polaris Energy Nicaragua S.A. (PENSA) and San Jacinto Power International Corporation (SJPIC), as borrowers, for the refinancing of their existing project finance debt in connection with PENSA’s operating 72 megawatt (net) geothermal power generating facility and the 10 megawatt (net) in-development binary plant addition thereto located in Telica, Department of León, Republic of Nicaragua.

The FSRU will be the first regasification vessel deployed off the coast of El Salvador.

Transelec Concesiones on the approximately $358 million loan facility and associated interest rate hedging for the portfolio construction financing of four transmission lines and four substations in Chile, with EDC, KfW IPEX-Bank and MUFG acting as mandated lead arrangers. This financing was provided to Transelec Concesiones through non-cross collateralized loans to each individual project on a standalone basis.
