FINANCIAL STATEMENTS AND EXHIBITS (B) General - On February 5, 2007, the General Partner (Geodyne Resources, Inc.) mailed a notice to the limited partners announcing that the Geodyne Energy Income Limited Partnership III-C (the "III-C Partnership")and the Geodyne Energy Income Limited Partnership III-D (the "III-D Partnership") (collectively, the "Partnerships") will terminate at the end of their current term, December 31, 2007. Consequently, the Partnerships adopted the liquidation basis of accounting effective February 5, 2007. The liquidation basis of accounting reports the net assets of the Partnerships at their net realizable value. Adjustments were made to reduce all balance sheet categories into one line, "net assets of Partnership in liquidation", which is an estimate of the net fair value of all Partnership assets and liabilities. Cash, accounts receivable, and accounts payable were valued at their historical cost, which approximates fair value. Oil and gas properties were valued at their estimated net sales price, which was estimated utilizing discounted cash flows based on strip pricing as of June 30, 2007 at a discount rate of 10% for proved developed producing reserves, 18% for proved developed non-producing reserves and 20% for proved undeveloped reserves. An adjustment was made to the discounted cash flows for the effects of gas balancing and asset retirement obligations. A provision was also made to account for direct expenses that will be incurred related to the sale of the oil and gas properties. The allocation of the "net assets of Partnership in liquidation" to the General Partner and limited partners was calculated using the current allocation of income and expenses, which may change if a Partnership's distributions from the commencement of the property investment period reach a yearly average equal to at least 12% of the limited partners subscriptions. The adoption of the liquidation basis of accounting on February 5, 2007 resulted in an increase in the III-C and III-D Partnerships' net assets of $13,008,489 and $7,833,968, respectively, at June 30, 2007. Pro forma unaudited financial information - A limited number of pro forma adjustments are required to illustrate the effects of the August 8, 2007 Oil and Gas Clearinghouse auction (the "August Auction") on the Unaudited Statements of Net Assets of Partnership in Liquidation, Unaudited Statements of Changes in Net Assets of Partnership in Liquidation, and Unaudited Statements of Operations.
