(1) | The tax provision for fiscal 2013 reflects a higher effective tax rate compared to the estimated annual effective rate at March 31, 2013. The March effective rate included the favorable effect depletion in excess of basis and was based on the Company's estimate of taxable ordinary income at that time. In contrast to the March forecast, actual taxable income for fiscal 2013 was lower due to a taxable loss on the sale of assets in June 2013 and lower than expected book income due to $0.6 million of lower Delhi Field revenue and $0.4 million of higher general and administrative expense, primarily attributable to an increase in accrued bonus, shelf registration costs and an engineering study.
