The following table summarizes the effects our natural gas hedge and our interest rate swap had on our financial position and results of operations for the year ended December 31, 2002: (a) Natural gas hedge assets and liabilities are classified in the balance sheet as energy trading contracts. Due to the volatility of gas commodity prices, it is probable that gas prices will increase and decrease over the remaining 19 months that these relationships are in place. (b)The actual amounts that will be reclassified to earnings could vary materially from this estimated amount due to changes in market conditions. Fair Value of Energy Trading Contracts The tables below show fair value of energy trading contracts outstanding for the year ended December 31, 2002, their sources and maturity periods: These contracts were valued through market exchanges and, where necessary, broker quotes and industry publications. The sources of the fair values of the financial instruments related to these contracts are summarized in the following table: (a)The Black Option Pricing model is a variant of the Black-Scholes Option Pricing model.		Effects of Accounting Changes — Accounting for Energy Trading Contracts In October 2002, the FASB, through the EITF, issued Issue No. 02-03, which rescinded Issue No. 98-10, “Accounting for Contracts Involved in Energy Trading and Risk Management Activities.” As a result, all new contracts that would otherwise have been accounted for under Issue No. 98-10 and that do not fall within the scope of SFAS No. 133 can no longer be marked-to-market and recorded in earnings as of October 25, 2002. We are not affected by this change in accounting principle and are not required to reclassify any of our contracts. EITF Issue No. 02-03 also requires that energy trading contracts and derivatives, whether settled financially or physically, be reported in the income statement on a net basis effective January 1, 2003. We began to classify our energy trading contracts on a net basis during the third quarter of 2002. On July 1, 2002, we began reporting mark-to-market gains and losses on energy trading contracts on a net basis, whether realized or unrealized, in our consolidated income statements. Prior to July 1, 2002, we reported gains on these contracts in sales and losses in cost of sales in our consolidated income statements. The changes are reflected in our consolidated financial statements for the year ended December 31, 2002. Prior periods shown in our consolidated financial statements have been reclassified to reflect the effect of this change and to be comparable as required by GAAP. As a result of the net presentation, we expect significant reductions in our energy revenues and expenses from those reported in prior periods, which will not affect gross profit or net income. A summary of the effects of this change for the years ended December 31, 2002, 2001 and 2000 is as follows:
