The factors that could cause actual results to differ materially from NJR's expectations include, but are not limited to, such things as weather, economic conditions and demographic changes in the New Jersey Natural Gas (NJNG) service territory, rate of NJNG customer growth, volatility of natural gas commodity prices, its impact on customer usage and NJR Energy Services's (NJRES) operations, the impact on the Company's risk management efforts, including commercial and wholesale credit risks, the impact of regulation (including the regulation of rates), fluctuations in energy-related commodity prices, conversion activity, other marketing efforts, actual energy usage patterns of NJNG's customers, the pace of deregulation of retail gas markets, access to adequate supplies of natural gas, the regulatory and pricing policies of federal and state regulatory agencies, changes due to legislation at the federal and state level, an adequate number of appropriate counterparties, sufficient liquidity in the energy trading market and continued access to the capital markets, the disallowance of recovery of environmental-related expenditures and other regulatory changes, environmental and other litigation and other uncertainties. While the Company periodically reassesses material trends and uncertainties affecting the Company's results of operations and financial condition in connection with its preparation of management's discussion and analysis of results of operations and financial condition contained in its Quarterly and Annual Reports, the Company does not, by including this statement, assume any obligation to review or revise any particular forward-looking statement referenced herein in light of future events.

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
