[1] Includes capital expenditures totaling approximately $1.4 billion for the remainder of 2014 through 2018 for construction of a natural gas pipeline system that has received applicable internal approvals, including approximately $855 million of equity contributions associated with a 33% equity investment in the northern portion of the natural gas pipeline system and $520 million for the southern portion, which includes AFUDC of approximately $1 million, $7 million, $20 million and $11 million for the remainder of 2014 through 2017, respectively. Construction of the natural gas pipeline system is subject to certain conditions, including FERC approval. A FERC decision is expected in 2015. See Contracts below.

[2] FPL has identified $1.5 billion to $2.5 billion in potential incremental capital expenditures through 2016 in addition to what is included in the table above.
