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 consolidated financial statements. There was a $254,000 decrease to the total amount of unrecognized tax benefits related to tax uncertainties during the nine months ended September 30, 2021. The decrease was the result of a payment of an assessment related to a California Franchise Tax Board (“FTB”) audit for tax years 2017 through 2019. 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 2018 through 2020 for federal taxes and 2011 through 2013 and 2020 for California state taxes. For tax years 2011 through 2013, the Company received Notices of Proposed Assessments (“NPAs”) and submitted a formal protest to the FTB in 2018. For tax years 2014 through 2016, the Company received NPAs related to the Company’s California apportionment factor and paid the total assessment with interest to the FTB in the third quarter of 2020. For tax years 2017 through 2019, the FTB issued Audit Issue Presentation Sheets with tax assessments related to the Company’s California apportionment factor, and the Company paid the total assessment with interest in the third quarter of 2021. If a reasonable settlement is not reached for tax years 2011 through 2013 for California state taxes, the Company intends to pursue other options, including a formal hearing with the FTB, an appeal with the California Office of Tax Appeals, or litigation in Superior Court. The Company believes that the resolution of these examinations and assessments will not have a material impact on the financial position of the Company. 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 September 30, 2021, the Company’s deferred income taxes were in a net liability position, which included a combination of ordinary and capital deferred tax expenses or 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.
