Income Taxes	Income Taxes It is our policy to estimate taxes for interim periods based on estimated annual effective tax rates which are derived, in part, from expected annual pre-tax income.

The tax expense of $5.9 million for the three months ended June 30, 2014 is comprised of a $5.6 million current tax expense and a $0.3 million deferred tax expense. The tax expense of $4.0 million for the six months ended June 30, 2014 is comprised of a $7.6 million current tax expense, net of a $3.6 million deferred tax benefit. The deferred tax benefit results from the application of the intraperiod tax allocation rules that allow for the benefitting of a current year loss in continuing operations when an increase to the valuation allowance is not required due to the existence of current year income reported elsewhere in the financial statements (e.g., discontinued operations, other comprehensive income). We recorded a deferred tax asset, net of deferred tax liabilities and valuation allowances, of $11.1 million as of June 30, 2014. Consistent with prior periods, it is considered appropriate to recognize a full valuation allowance against all categories of deferred tax assets other than gross unrealized losses on available-for-sale debt securities, due to the significant negative evidence of historical cumulative U.S. GAAP losses and the uncertainty of consistent future U.S. GAAP earnings. We have concluded that a valuation allowance on the deferred tax assets attributable to available-for-sale debt securities with gross unrealized losses was not required due to our ability and intent to hold these securities until recovery of fair value or contractual maturity, thereby avoiding realization of taxable capital losses. This conclusion is consistent with prior periods. For the three months ended June 30, 2014, we recognized a net decrease in the valuation allowance of $3.9 million. For the six months ended June 30, 2014, we recognized a net increase in the valuation allowance of $11.5 million. In accordance with the intraperiod tax allocation rules, the change in the valuation allowance has been allocated to various financial statement components of income or loss. The Company and its subsidiaries file consolidated, combined, unitary or separate income tax returns in the U.S. federal, various state and foreign jurisdictions. The Company is no longer subject to U.S. federal income tax examinations by tax authorities for years before 2011. Based upon the timing and status of our current examinations by taxing authorities, we do not believe that it is reasonably possible that any changes to the balance of unrecognized tax benefits occurring within the next 12 months will result in a significant change to the results of operations, financial condition or liquidity. In addition, we do not anticipate that there will be additional payments made or refunds received within the next 12 months with respect to the years under audit. We do not anticipate any increases to the existing unrecognized tax benefits that would have a significant impact on the financial position of the Company.

Income Taxes

It is our policy to estimate taxes for interim periods based on estimated annual effective tax rates which are derived, in part, from expected annual pre-tax income. However, the change in the deferred income balances, income tax benefit and expense and related valuation allowance for the three and six months ended June 30, 2014 have been computed based on the first six months of 2014 as a discrete period.

The tax expense of $5.9 million for the three months ended June 30, 2014 is comprised of a $5.6 million current tax expense and a $0.3 million deferred tax expense. The tax expense of $4.0 million for the six months ended June 30, 2014 is comprised of a $7.6 million current tax expense, net of a $3.6 million deferred tax benefit. The deferred tax benefit results from the application of the intraperiod tax allocation rules that allow for the benefitting of a current year loss in continuing operations when an increase to the valuation allowance is not required due to the existence of current year income reported elsewhere in the financial statements (e.g., discontinued operations, other comprehensive income).

We recorded a deferred tax asset, net of deferred tax liabilities and valuation allowances, of $11.1 million as of June 30, 2014. Consistent with prior periods, it is considered appropriate to recognize a full valuation allowance against all categories of deferred tax assets other than gross unrealized losses on available-for-sale debt securities, due to the significant negative evidence of historical cumulative U.S. GAAP losses and the uncertainty of consistent future U.S. GAAP earnings.

This conclusion is consistent with prior periods.

For the three months ended June 30, 2014, we recognized a net decrease in the valuation allowance of $3.9 million. For the six months ended June 30, 2014, we recognized a net increase in the valuation allowance of $11.5 million.
