On April 30, 1996, the Company purchased interests in certain producing and non-producing oil and gas properties, including approximately 14,000 net acres of unevaluated leasehold, from Amerada Hess Corporation for $37.8 million. The properties are located in the Knox and Golden Trend fields of southern Oklahoma, most of which are operated by the Company. In fiscal 1996 the reserves acquired from Amerada Hess Corporation were included in both "Extensions, discoveries and other additions" and "Purchase of reserves inplace". The fiscal 1996 presentation has been restated in the current year to remove the acquired reserves from "Extensions, discoveries and other additions" with a corresponding offset to "Revisions of previous estimate". This revision resulted in no net change to total oil and gas reserves. Standardized Measure of Discounted Future Net Cash Flows (unaudited) Statement of Financial Accounting Standards No. 69 ("SFAS 69") prescribes guidelines for computing a standardized measure of future net cash flows and changes therein relating to estimated proved reserves. The Company has followed these guidelines which are briefly discussed below. Future cash inflows and future production and development costs are determined by applying year-end prices and costs to the estimated quantities of oil and gas to be produced. Estimates are made of quantities of proved reserves and the future periods during which they are expected to be produced based on year-end economic conditions. Estimated future income taxes are computed using current statutory income tax rates including consideration for the current tax basis of the properties and related carryforwards, giving effect to permanent differences and tax credits. The resulting future net cash flows are reduced to present value amounts by applying a 10% annual discount factor. Since December 31, 1997 oil and gas prices have declined, with oil prices reaching ten-year lows in March 1998. In addition, the Company has completed several acquisitions based on expectations of higher oil and gas prices than those currently being received. Based on NYMEX oil prices of $16.50 per Bbl and NYMEX gas prices of $2.35 per Mcf in effect on March 25, 1998, and estimates of the Company's proved reserves as of December 31, 1997 (pro forma for the acquisitions completed during the quarter ended March 31, 1998), the Company estimates it will incur an additional full cost ceiling write down of between $175 million and $200 million as of March 31, 1998. If this occurs, the Company will incur a substantial loss for the first quarter of 1998 which would further reduce shareholders' equity. The assumptions used to compute the standardized measure are those prescribed by the Financial Accounting Standards Board and, as such, do not necessarily reflect the Company's expectations of actual revenue to be derived from those reserves nor their present worth. The limitations inherent in the reserve quantity estimation process, as discussed previously, are equally applicable to the standardized measure computations since these estimates are the basis for the valuation process. The following summary sets forth the Company's future net cash flows relating to proved oil and gas reserves based on the standardized measure prescribed in SF AS 69: June 30,
