| c. | Deferred Taxes
The Company’s deferred income taxes are primarily due to temporary differences between financial and income tax reporting for incentive compensation, depreciation of property, plant and equipment, amortization of intangibles, inventory adjustments, other accrued liabilities and net operating loss carryforwards (“NOLs”). Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Companies are required to assess whether valuation allowances should be established against their deferred tax assets based on the consideration of all available evidence, both positive and negative, using a “more likely than not” standard. In making such judgments, significant weight is given to evidence that can be objectively verified. The Company assesses, on a quarterly basis, the realizability of its deferred tax assets by evaluating all available evidence, both positive and negative, including: (1) the cumulative results of operations in recent years, (2) the nature of recent losses, if applicable, (3) estimates of future taxable income, (4) the length of NOLs and (5) the uncertainty associated with a possible change in ownership, which imposes an annual limitation on the use of these carryforwards. As of December 31, 2016 and 2015, the Company retained a valuation allowance of $1.2 and $1.2 million, respectively, against deferred tax assets related to various state and local NOLs that are subject to restrictive rules for future utilization. As of December 31, 2016, the Company had no U.S. federal tax NOLs. The Company had various multistate income tax NOLs, which have been recorded as a deferred income tax asset of approximately $2.3 million, before valuation allowances. These NOLs will expire beginning in 2017, if unused. The components of deferred tax assets and deferred tax liabilities as of December 31, 2016 and 2015 were as follows (in thousands):
|  | 2016 |  | 2015 |
Deferred tax assets |  |  |  |  |  |  |
Tax credits and loss carryforwards |  | $ | 260 |  | $ | 563 |

| d. | Tax Reserves
The Company’s policy with respect to interest and penalties associated with reserves or allowances for uncertain tax positions is to classify such interest and penalties in Income Tax Expense on the Consolidated Statement of Operations. As of December 31, 2016 and 2015, the total amount of unrecognized income tax benefits was approximately $12.7 million and $11.7 million, respectively, all of which, if recognized, would impact the effective income tax rate of the Company. As of December 31, 2016 and 2015, the Company had recorded a total of $1.8 and $1.1 million, respectively of accrued interest and penalties related to uncertain tax positions. The Company foresees no significant changes to the facts and circumstances underlying its reserves and allowances for uncertain income tax positions as reasonably possible during the next 12 months. As of December 31, 2016, the Company is subject to unexpired statutes of limitation for U.S. federal income taxes for the years 2003 through 2016. The Company is also subject to unexpired statutes of limitation for Indiana state income taxes for the years 2014 through 2016. A reconciliation of the beginning and ending amount of unrecognized tax benefits was as follows (in thousands) and all balances as of December 31, 2016 were included in either Other Noncurrent Liabilities or Deferred Income Taxes in the Company’s Consolidated Balance Sheet:
