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, the positions are “more-likely-than-not” 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 $0.2 million increase to the total amount of unrecognized tax benefit related to tax uncertainties during the three months ended March 31, 2016. The increase was the result of tax positions taken regarding 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 benefits to have a significant impact on its consolidated financial statements within the next 12 months. The Company and its subsidiaries file income tax returns with the Internal Revenue Service and the taxing authorities of various states. Tax years that remain subject to examination by major taxing jurisdictions are 2012 through 2014 for federal taxes, and 2003 through 2014 for California state taxes. The Company is currently under examination by the California Franchise Tax Board (“FTB”) for tax years 2003 through 2013. The FTB issued Notices of Proposed Assessments to the Company for tax years 2003 through 2010, which the Company formally protested. The proposed adjustments for tax years 2003 through 2006 were affirmed following an administrative protest process with the FTB examination. The Company is in settlement discussions with the FTB. If a reasonable settlement is not reached, the Company intends to pursue other options, including a formal hearing with the State Board of Equalization or litigation in superior court. Management believes that the resolution of these examinations and assessments will not have a material impact on the Company's 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. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates or laws is recognized in earnings in the period that includes the enactment date. At March 31, 2016, 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 Company’s ability to realize 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.
