Efficiency Performance Measures

| (vi) Indirect Line Cost per Gas Customer | $90.31 | $85.30 | $92.66 | $91.31 | $73.35 |
Notes:
(a) This calculation excludes current borrowings, interdivisional account, other financial assets and liabilities from working capital. Borrowings and the interdivisional account are excluded because they do not relate to operational obligations. Other financial assets and liabilities are excluded as they relate to derivatives which have been excluded from EBIT as noted in (b) below.
(b) EBIT for the purposes of this calculation excludes the derivative losses of $0.60 million as shown in the Comprehensive Income Statement, as other losses. This is because the derivative loss does not meet the definition of revenue in the Gas (Information Disclosure) Regulations 1997, because it is associated with funding costs which are excluded from EBIT.
