Food for Thought "Standard and Poor's screened the broad-market S&P 1500 universe, looking for companies with at least a 10-year history of long-term earnings growth, continual dividend payments and low volatility. Just one name popped up: New Jersey Resources Corp., the parent of the utility New Jersey Natural Gas, among other subsidiaries." The Wall Street Journal February 3, 2005

Appendix A: Gross Margin Gross margin is a non-GAAP measure. NJNG's gross margin is defined as gas revenues less gas purchases, sales tax and a Transitional Energy Facilities Assessment (TEFA), which is included in Energy and other taxes on the Consolidated Statements of Income. Management believes that gross margin provides a more meaningful basis for evaluating utility operations than does revenues since natural gas costs, sales tax and TEFA are passed through to customers and, therefore, have no effect on gross margin. NJRES’ gross margin is defined as natural gas revenues and management fees less natural gas costs. For reconciliation to our revenue, see our periodic SEC filings available on our Web site at njliving.com
