Recognize PMT Crew in the audience

Commitment to service Story – This past Christmas night, (you may remember that it was cold, snowing and very windy) an electric line fell from the poll onto our line on Whitesville Road in Jackson, a major line feeding Ocean County. The arcing caused the line to rupture. Rather than taking the line off service, which would have caused a major service disruption for thousands of customers in Ocean County, our service crew worked for 72 hours to construct a temporary bypass line around the rupture, thereby avoiding an outage and keeping thousands warm. We asked a few of the members of that service crew to join us here today. (Gary E to supply names)

Why is NJRES Different? Strictly natural gas operation - no electric exposure - no California trading Not a speculative trader Manage assets for primarily hedged positions Selected fee-based services Trade around "assets" "Assets" consist of capacity/storage contracts vs. power plants, etc. Physical assets reduce risk Our "assets" require less long-term capital

#####

Risk management guidelines Limited open positions = low VAR (less than $1 million) Provides internal controls Credit procedures in place Daily compliance monitoring by financial department Minimal mark-to-market income (less than 1 percent) Trader compensation not based on sales volumes or revenues Netting agreements potentially reduces credit risk Why is NJRES Different?
