| Note 2. Income Taxes | |
| In accordance with generally accepted accounting principles, the Company has analyzed its filing positions in federal and state income tax returns that remain subject to examination, generally 3 years after filing. The Company believes that all filing positions are highly certain and that all income tax filing positions and deductions would be sustained upon a taxing jurisdiction’s audit. Therefore, no reserve for uncertain tax positions is required. No interest or penalties have been levied against the Company and none are anticipated. |
