On December 31, 2013, OPCo assigned the $1 billion in credit facility borrowings to AGR upon the transfer of OPCo’s generation assets to AGR. Also on December 31, 2013, AGR subsequently assigned a portion of the borrowings to APCo in the amount of $300 million upon AGR’s transfer of certain of those generation assets.
