SUBSEQUENT EVENT:

In July 2012, SJG filed a petition with the BPU requesting approval for an infrastructure replacement and improvement program that would operate in the same manner as SJG's existing CIRT. The petition requests approval for infrastructure improvement projects over the next five years totaling approximately $250.0 million that are incremental to SJG's normal capital projects scheduled over that same time period.  Under the program, SJG would spend $50.0 million per year for this work and is requesting the ability to earn a return of and a return on these investments. This petition is pending.
