[1] The Joliet facility is currently in the process of converting to natural gas.

[2] On May 24, 2016, S&P lowered its corporate credit rating on GenOn Energy Inc. and affiliates (including NRG REMA) to "CCC" from "CCC+" due to a weaker forward power curve, milder weather patterns and weakening financial measures. PSEG continues to monitor any changes to GenOn's status and potential impacts on Energy Holdings' lease investments.

[3] NRG REMA, LLC (NRG REMA) notified PJM that it deactivated the coal-fired units at the Shawville generating facility in June 2015 and has disclosed that it expects to return the Shawville units to service in the fall of 2016 with the ability to use natural gas.
