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.
