| Summary of Significant Accounting Policies | ||||
| (a)Basis of Accounting: | ||||
| The condensed financial statements of the Trust, as prepared on the modified cash basis, reflect the Trust’s assets, liabilities, trust corpus, and distributable income as follows: | ||||
| 1.Royalty income and interest income are recognized in the month in which amounts are received by the Trust. | ||||
| 2.Trust expenses, consisting principally of routine general and administrative costs, include payments made during the accounting period. | ||||
| 3.Reserves for liabilities that are contingent or uncertain in amount may also be established if considered necessary. | ||||
| 4.Net royalty and overriding royalty interests that are producing properties are amortized using the unit-of-production method. This amortization is shown as a reduction of Trust corpus. | ||||
| 5.Distributions to Unit Holders are recognized when declared by the Trustee. | ||||
| 6.Production withholding taxes withheld from Unit Holder distributions and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from royalty income in the condensed statement of distributable income. | ||||
| The condensed financial statements of the Trust differ from financial statements prepared in conformity with GAAP because of the following: | ||||
| · | Royalty income and interest income are recognized in the month received rather than in the month of production. | |||
| · | Expenses generally are not accrued. | |||
| · | Amortization of the net royalty and overriding royalty interests is shown as a reduction to Trust corpus and not as a charge to operating results. | |||
| · | Reserves may be established for contingencies that would not be recorded under GAAP. | |||
| These condensed statements differ from financial statements prepared in accordance with GAAP and were prepared on the modified cash basis of reporting, which is considered to be the most meaningful because Distributions to Unit Holders are based on net cash receipts. This comprehensive basis of accounting, other than GAAP, corresponds to the accounting permitted for royalty trusts by the U.S. Securities and Exchange Commission as specified by Staff Accounting Bulletin Topic 12E, Financial Statements of Royalty Trusts. | ||||
| (b)Cash and Cash Equivalents: | ||||
| The Trust considers all highly liquid financial instruments with original maturities of three months or less when purchased to be cash equivalents. | ||||
| (c)Related Party: | ||||
| The Trust was organized to provide an efficient, orderly and practical means of administering the income received from royalty interests and is administered by the Trustee. Pursuant to the terms of the Trust Indenture, the Trust pays the Trustee $80,000 per year. The Trustee may readjust this fee annually in its sole discretion. The Trust pays a Trustee fee of $20,000 per quarter as long as the Trust has sufficient royalty income to make such payments. | ||||
| (d)Subsequent Events: | ||||
| We have evaluated the Trust activity and have concluded that there are no material subsequent events requiring additional disclosure or recognition in these condensed financial statements. | ||||
