Development Costs
Development costs deducted are based on the current level of development expenditures, budgeted future development costs and the cumulative actual costs under (over) previous deductions. XTO Energy has advised the Trustee that actual development costs were charged to the Trust as incurred. These development costs increased 388% for the second quarter and 305% for the six-month period primarily due to drilling costs on a non-operated well. For further information on development costs, see Note 2 to Condensed Financial Statements.
Overhead
Overhead decreased 2% for the second quarter and 3% for the six-month period. Overhead is charged by XTO Energy and other operators for administrative expenses incurred to support operations of the underlying properties. Overhead fluctuates based on changes in the active well count and drilling activity on the underlying properties, as well as an annual cost level adjustment based on an industry index.
Excess Costs
If monthly costs exceed revenues for any conveyance, these excess costs must be recovered, with accrued interest, from future net proceeds of that conveyance and cannot reduce net profits income from another conveyance. Underlying cumulative excess costs for the Kansas, Oklahoma and Wyoming conveyances remaining as of June 30, 2021 totaled $32.6 million ($26.1 million net to Trust), including accrued interest of $2.7 million ($2.1 million net to Trust). This balance does not include the approximately $14.6 million of additional production costs the Panel determined could be charged in the second interim final award of the Chieftain arbitration. For further information on excess costs, see Note 5 to Condensed Financial Statements.
Other Proceeds
The calculation of net profits income for the quarter ended June 30, 2021 included $86,198 ($68,958 net to the Trust) from XTO Energy due to interest received on past due payments. The calculation of net profits income for the six-month period included $89,007 ($71,206 net to the Trust) from XTO Energy due to interest received on past due payments.
