Under the provisions of SFAS No. 142, Goodwill and Other Intangible Assets (SFAS 142), the Company amortizes the intangible asset acquired as part of the purchase of Blacksand (see Note 3) over the period in which the asset is expected to contribute to future cash flows, which is consistent with the life of the underlying oil and gas reserves. The amortized intangible asset is evaluated for impairment in accordance with SFAS No. 144 Accounting for the Impairment or Disposal of Long-Lived Assets when events and circumstances indicate that the asset might be impaired.
