Income Tax Disclosure	`Note 9.` `Income Taxes` The provisions for income taxes shown in the Condensed Consolidated Statements of Income were computed based on the Company's actual results, which approximate the effective tax rate expected to be applicable for the balance of the current fiscal year in accordance with consolidated life/non-life group income tax regulations. Such regulations adopt a subgroup method in determining consolidated taxable income, whereby taxable income is determined separately for the life insurance company group and the non-life insurance company group. As a result of the winding down of operations and dissolution of IHC Administrative Services, Inc. (“IHC AS”), a subsidiary of IHC, in the quarter ended June 30, 2017, the Company recognized an estimated $11,589,000 income tax benefit on a worthless stock deduction of $33,110,000 representing the Company’s tax basis related to its unrecovered investment in IHC AS. Management believes that it is more likely than not that the Company will realize the income tax benefit of this worthless stock deduction. Excluding this tax benefit, the differences between the Federal statutory income tax rate of 35% and the Company’s effective income tax rate resulted principally from the dividends received deduction and tax exempt interest income, state and local income taxes, and health insurer specific tax provisions.
