The measurement of the unrecognized tax benefit was recently reassessed due to recent developments related to the issue, and the Company now believes that the full amount of the tax benefit has a greater than 50% chance of being fully realized. During the nine months ended September 30, 2010, earnings were impacted favorably by $3.3 million due to the aforementioned issue, the release of an unrecognized income tax benefit liability that related to a tax-basis policy liability issue, and the closing of the 2005 tax years statute of limitations. The Company reassessed the tax-basis policy liability issue due to recent technical guidance that confirmed the Companys historical calculations. Within the next twelve months, the Company does not expect to have any material adjustments to its unrecognized income tax benefits liability with regard to any of the tax jurisdictions in which it conducts its business operations.   The Company has computed its effective income tax rate for the three and nine months ended September 30, 2010, based upon its estimate of its annual 2010 income. For the three and nine months ended September 30, 2009, due to the unpredictability at that time of future investment losses and certain elements of operating income, the Company was not able to reasonably estimate an expected annual effective tax rate. Instead, the Company computed an effective income tax rate based upon year-to-date reported income. The effective tax rate for the three and nine months ended September 30, 2010, was 34.2% and 33.5%, respectively, and 33.7% and 34.4% for the three and nine months ended September 30, 2009, respectively.   Based on the Companys current assessment of future taxable income, including available tax planning opportunities, the Company anticipates that it is more likely than not that it will generate sufficient taxable income to realize all of its material deferred tax assets.  The Company did not record a valuation allowance against its material deferred tax assets as of September 30, 2010.</td></tr></table> 12.                          & false false false us-types:textBlockItemType textblock Description containing the entire income tax disclosure.
