Income Tax, Policy	The provision for deferred income taxes is based on the asset and liability method of accounting for income taxes. Under this method, deferred income taxes are recognized by applying enacted statutory tax rates to temporary differences between amounts reported in the Consolidated Financial Statements and the tax bases of existing assets and liabilities in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is recognized for the portion of deferred tax assets that, in management's judgment, is not likely to be realized.  A liability for uncertain tax positions is recorded when it is more likely than not that a tax position will not be sustained upon examination by taxing authorities. The effect on deferred income taxes of a change in tax rates or laws is recognized in income tax expense in the period that includes the enactment date.   The Company uses a portfolio approach to release income tax effects from accumulated other comprehensive income. The portfolio approach involves a strict period-by-period cumulative incremental allocation of income taxes to the change in unrealized gains and losses reflected in other comprehensive income. Under this approach, the net cumulative tax effect is ignored. The net change in unrealized gains or losses recorded in accumulated other comprehensive income under this approach would be eliminated only on the date the entire inventory of available-for-sale securities is sold or otherwise disposed of.      Interest and penalties, if any, are included in income tax expense in the Consolidated Statements of Income.
