The Group has identified three operating segments: ‘All other segments’ include amounts of a corporate nature not specifically attributable to an operating segment. The following items and associated assets and liabilities are not allocated to operating segments as they are not considered part  of the core operations of any segment but are reviewed by the chief operating decision maker on a regular basis: Employee benefits expenses and other operating expenses, that are associated with the exploration and evaluation activities and  specifically relate to an area of interest, are allocated to the area of interest and are capitalised as exploration and evaluation assets. Segment revenues and results do not include transfers between segments as intercompany balances are eliminated on consolidation. The amounts provided to the chief operating decision maker with respect to total assets are measured in a manner consistent  with that of the financial statements. Reportable segment assets are equal to consolidated total assets. 65 Karoon Gas Australia Ltd  Annual Report 2011 •  interest income; •  net foreign currency gains (losses); •  finance costs; •  net employee benefits expense (including non-cash share-based payments expense of $5,069,475 (2010: $5,289,047)); •  administration and other operating expenses (including Brazilian initial public offering expenses of $5,673,914 (2010:  $407,317)); •  depreciation and amortisation expense; •  property costs; and •  income tax expense.
