Deferred Income Taxes 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 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-planing 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. The following table presents the significant components of the Company’s net deferred tax assets and liabilities:
| December 31,
| 2015 |  | 2014
| (Amounts in thousands)
Deferred tax assets: |  |  |
20% of net unearned premium | $ | 75,406 |  |  | $ | 71,907 |
Discounting of loss reserves and salvage and subrogation recoverable for tax purposes | 9,518 |  |  | 11,100 |
Write-down of impaired investments | 857 |  |  | 942 |
Tax credit carryforward | 36,349 |  |  | 31,198 |
Expense accruals | 11,264 |  |  | 13,395 |
Other deferred tax assets | 9,596 |  |  | 7,448 |
Total gross deferred tax assets | 142,990 |  |  | 135,990 |

The Company had an alternative minimum tax credit carryforward balance of $36.3 million and $31.2 million at December 31, 2015 and 2014, respectively, which is not subject to expiration. Uncertainty in Income Taxes 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 $0.4 million decrease to the total amount of unrecognized tax benefits related to tax uncertainties during 2015. The decrease 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 consolidated financial statements. The following table presents a reconciliation of the beginning and ending balances of unrecognized tax benefits:
| December 31,
| 2015 |  | 2014
| (Amounts in thousands)
Balance at January 1 | $ | 12,612 |  |  | $ | 10,784 |
Additions based on tax positions related to: |  |  |
Current year | 932 |  |  | 2,277 |
Prior years | (1,379 | ) |  | (258 | )
Additions (reductions) as a result of lapse of the applicable statute of limitations | — |  |  | (191 | )
Balance at December 31 | $ | 12,165 |  |  | $ | 12,612 |
As presented above, the balances of unrecognized tax benefits were $12.2 million and $12.6 million at December 31, 2015 and 2014, respectively. Of these totals, $10.9 million and $11.1 million represent unrecognized tax benefits, net of federal tax benefit and accrued interest expense which, if recognized, would impact the Company’s effective tax rate. Management does not expect the Company's total amount of unrecognized tax benefits to materially increase within the next twelve months. The Company recognizes interest and penalties related to unrecognized tax benefits as a part of income taxes. During the years ended December 31, 2015, 2014, and 2013, the Company recognized net interest and penalty expense, excluding refunds, of $112,000, $739,000, and $1,119,000, respectively. The Company carried an accrued interest and penalty balance of $2,915,000 and $2,803,000 at December 31, 2015 and 2014, respectively.
