Determinants of intramethod choice in the oil and gas industry

Abstract Procedural flexibility can have a substantial impact on reported costs, revenues, expenses, and balance sheet valuations. Until 1978 oil and gas companies had considerable flexibility in applying full cost and successful efforts. A unique opportunity to measure the income effect of firms' procedural choices occurred when the SEC specified the exact procedures that must be followed by oil and gas producers when they account for exploratory and development costs under both the full cost and successful efforts methods. In complying with the new rules firms were required to adjust retained earnings retroactively to reflect what it would have been if the new procedures had been in effect all along. These retained earnings adjustments provide a measure of the income effect of procedural choices. This study shows that economic incentives influence the procedural accounting choices which were made by oil and gas producers. The same economic incentives also influence the choice of full cost or successful efforts. Finally, the discriminatory ability of firms' economci incentives is most powerful when firms' reporting strategies are defined in terms of both choice of accounting methods and procedural applications within those methods.
