Then, the focus of this study to examine factors that influence the choice of accounting policy for DD&A.

Questionnaire and documentary review were used as data collection methods while hierarchical multiple regression was used as data analysis techniques. The findings revealed that company’s structure as the organisational characteristics significantly and positively predicts the choice of reducing balance accounting methods. Firm age significantly and positively predicted the choice of the straight-line method; however, it is relatively weak and reducing balance method. It was further revealed that disclosure requirements had significant positive influence on the choice of the straight-line, reducing balance and unit of production accounting methods. It was further revealed that capital market requirements had different mediating effect on the influence of the selected organisation characteristics and disclosure requirements on the choice of accounting methods for DD and A.
