Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: Tax positions taken or expected to be taken in a tax return by the Company are recognized in the financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. To the best of management's knowledge, there are no tax uncertainties that are expected to result in significant increases or decreases to unrecognized tax benefits within the next twelve month period. The Company views its income tax exposures as primarily consisting of timing differences whereby the ultimate deductibility of a taxable amount is highly certain but the timing of its deductibility is uncertain. Such differences relate principally to the timing of deductions for loss and premium reserves. As in prior examinations, the Internal Revenue Service ("IRS") could assert that claim reserve deductions were overstated thereby reducing the Company's statutory taxable income in any particular year. The Company believes that it establishes its reserves fairly and consistently at each balance sheet date, and that it would succeed in defending its tax position in these regards. Because of the impact of deferred tax accounting, the possible accelerated payment of tax to the IRS would not necessarily affect the annual effective tax rate. The IRS is currently examining the Company's 2008 consolidated Federal income tax return, along with the Company's amended returns for the years 2005 through 2007 relative to a claim for recovery of taxes previously paid. The Company's consolidated 2006 Federal income tax return has been examined and no significant adjustments have been identified. The Company classifies interest and penalties as income tax expense in the consolidated statement of income.

Income Taxes:

Tax positions taken or expected to be taken in a tax return by the Company are recognized in the financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. To the best of management's knowledge, there are no tax uncertainties that are expected to result in significant increases or decreases to unrecognized tax benefits within the next twelve month period. The Company views its income tax exposures as primarily consisting of timing differences whereby the ultimate deductibility of a taxable amount is highly certain but the timing of its deductibility is uncertain. Such differences relate principally to the timing of deductions for loss and premium reserves. As in prior examinations, the Internal Revenue Service ("IRS") could assert that claim reserve deductions were overstated thereby reducing the Company's statutory taxable income in any particular year. The Company believes that it establishes its reserves fairly and consistently at each balance sheet date, and that it would succeed in defending its tax position in these regards. Because of the impact of deferred tax accounting, the possible accelerated payment of tax to the IRS would not necessarily affect the annual effective tax rate. The IRS is currently examining the Company's 2008 consolidated Federal income tax return, along with the Company's amended returns for the years 2005 through 2007 relative to a claim for recovery of taxes previously paid.
