Note 4 - Asset Retirement Obligations
The estimated valuation of asset retirement obligations ("AROs") is based on management's historical experience and best estimate of plugging and abandonment costs by field. Assumptions and judgments made by management when assessing an ARO include: (i) the existence of a legal obligation; (ii) estimated probabilities, amounts, and timing of settlements; (iii) the credit-adjusted risk-free rate to be used; and (iv) inflation rates. Accretion expense is recorded under depletion, depreciation, amortization, and accretion in the unaudited condensed consolidated statement of operations.
The following table summarizes the asset retirement obligation activity for the nine months ended March 31, 2013:
