Income Taxes	Income Taxes For financial statement purposes, the Company recognizes tax benefits related to positions taken, or expected to be taken, on a tax return only if, “more-likely-than-not,” the positions are sustainable. Once this threshold has been met, the Company's measurement of its expected tax benefits is recognized in its financial statements. There was a $4.7 million increase to the total amount of unrecognized tax benefit related to tax uncertainties during the nine months ended September 30, 2013. The increase was the result of tax positions taken regarding federal tax credit carryforwards and state tax apportionment issues based on management’s best judgment given the facts, circumstances, and information available at the reporting date. The Company does not expect any changes in such unrecognized tax benefit to have a significant impact on its consolidated financial statements within the next 12 months. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states. Tax years that remain subject to examination by major taxing jurisdictions are 2010 through 2012 for federal taxes and 2003 through 2011 for California state taxes. Tax year 2010 is currently under examination by the Internal Revenue Service (“IRS”). The IRS has issued adjustments to the Company’s 2010 tax liability which will generate a net tax refund. The Company has agreed with these adjustments and anticipates the exam will conclude in the near future. The Company is currently under examination by the California Franchise Tax Board (“FTB”) for tax years 2003 through 2010. The FTB has issued Notices of Proposed Assessments to the Company for tax years 2003 through 2006. The Company has filed protests with the FTB in response to these assessments and presented its case in a hearing before the FTB. No assessments have been received for tax years 2007 through 2010. Management believes that the resolution of these examinations and assessments will not have a material impact on the condensed consolidated financial statements. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial reporting basis and the respective tax basis of the Company’s assets and liabilities, and expected benefits of utilizing net operating loss, capital loss, and tax-credit carryforwards. The Company assesses the likelihood that its deferred tax assets will be realized and, to the extent management does not believe these assets are more likely than not to be realized, a valuation allowance is established. At September 30, 2013, the Company’s deferred income taxes were in a net asset position which included a combination of ordinary and capital deferred tax benefits. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon generating sufficient taxable income of the appropriate character within the carryback and carryforward periods available under the tax law. Management considers the reversal of deferred tax liabilities, projected future taxable income of an appropriate nature, and tax-planning strategies in making this assessment. The Company believes that through the use of prudent tax planning strategies and the generation of capital gains, sufficient income will be realized in order to maximize the full benefits of its deferred tax assets. Although realization is not assured, management believes that it is more likely than not that the Company’s deferred tax assets will be realized.
