Slift - regarding your excellent analysis of the overheads, the missing $30m from the overheads assessment may be due to depreciation and impairment as per the annual report - see notes 2.3 viz ;
Oil and gas assets – depreciation
Oil and gas properties are depreciated from the commencement of production on a unit-of-production basis. This is the ratio of oil and gas production in the period to the estimated reserves base, which is proved plus probable reserves (2P reserves), at the end of the period, plus the production in the period, on a field-by-field basis. Costs used in the unit-of-production calculation comprise the net carrying amount of capitalised costs, taking into account future development expenditures necessary to bring those reserves into production.
Impairment
An impairment test is performed whenever events and circumstances arising during the development or production phase indicate that the carrying value of an oil and gas property may exceed its recoverable amount.
The carrying value is compared against the expected recoverable amount of the asset, generally by reference to the present value of the future net cash flows expected to be derived from production of commercial reserves. The cash-generating unit applied for impairment test purposes is generally the field, except that a number of field interests may be grouped as a single cash-generating unit where the cash inflows of each field are interdependent.
Any impairment identified is charged to the income statement. Where conditions giving rise to impairment subsequently reverse, the effect of the impairment charge is also reversed as a credit to the income statement, net of any depreciation that would have been charged since the impairment.
