The Company uses the liability method of accounting for income taxes as set forth in ASC 740. Under the liability method, deferred taxes are determined based on differences between the financial statement and tax bases of assets and liabilities using enacted tax rates. As of December 31, 2020, the Company had Federal and California net operating loss carryforwards of approximately $69.1 million and $89.4 million, respectively. The Federal and California net operating loss carryforwards will expire at various dates from 2027 through 2040; however, $49.8 million of the Federal operating loss does not expire and will be carried forward indefinitely. Pursuant to Internal Revenue Code Sections 382 and 383, use of the Company's net operating loss and credit carryforwards may be limited if a cumulative change in ownership of more than 50% occurs within any three years' period since the last ownership change.

Significant components of the Company's deferred tax assets (liabilities) as of December 31, 2020 and December 31, 2019 are shown below (in thousands). A valuation allowance of $15.5 million and $8.2 million as of December 31, 2020 and December 31, 2019, respectively, has been established against the Company's deferred tax assets related to loss entities the Company cannot consolidate under the Federal consolidation rules, as realization of these assets is uncertain. Valuation allowance increased by $7.3 million in 2020.

The Company's effective tax rate is different from the federal statutory rate of 21% due primarily to state taxes, change in valuation allowance, and permanent adjustments. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was enacted and signed into law. The CARES Act, among other things, permits NOL carryovers and carrybacks and modifications on the limitation of business interests. As of December 31, 2020, the Company does not expect the CARES Act to result in any material impact on the Company’s effective tax rate.

As of December 31, 2020 and 2019, the Company does not have any unrecognized tax benefits related to various federal and state income tax matters. The Company will recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense.The Company is subject to U.S. federal income tax as well as income tax in California. The Company and its subsidiaries' state and Federal income tax returns are open to audit under the statute of limitations for the years ended December 31, 2016 through December 31, 2019 and for the years ended December 31, 2017 through December 31, 2019, respectively.
