Our net deferred tax liability of $91.5 million as of December 31, 2016 and $78.6 million as of December 31, 2015 is classified as Deferred Income Taxes in the accompanying Consolidated Balance Sheets. Income taxes receivable included in Receivables, net totaled $11.6 million at December 31, 2016 and $11.7 million at December 31, 2015. At December 31, 2016, we had $80.8 million of gross domestic state net operating loss carryforwards and capital loss carryforwards, and $4.1 million of state tax credits, all of which result in a deferred tax asset of $6.0 million and expire from 2017 through 2036. At December 31, 2016, we had $2.5 million of valuation allowance related to these loss carryforwards. In assessing the realizability of deferred tax assets, we consider whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. We provide valuation allowances to offset portions of deferred tax assets due to uncertainty surrounding the future realization of such deferred tax assets. We adjust the valuation allowance in the period management determines it is more likely than not that deferred tax assets will or will not be realized. We file income tax returns in the U.S. federal jurisdiction and various states. As a matter of course, various taxing authorities, including the IRS, regularly audit us. These audits may result in proposed assessments where the ultimate resolution may result in our owing additional taxes. Currently, no tax years are under examination by the IRS and tax years from 2009 to 2015 are under examination by U.S. state jurisdictions. We believe that our tax positions comply with applicable tax law and that we have adequately provided for these matters. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
| 2016 |  | 2015 |  | 2014
Balance at January 1 | $ | 5.6 |  |  | $ | 4.9 |  |  | $ | 4.8 |
Additions based on tax positions related to the current year | — |  |  | — |  |  | — |
Additions for tax positions of prior years | 0.8 |  |  | 0.7 |  |  | 0.9 |
Reductions for tax positions of prior years | (0.4 | ) |  | — |  |  | (0.1 | )
Reductions for expirations of statute of limitations | (0.2 | ) |  | — |  |  | (0.4 | )
Settlements | — |  |  | — |  |  | (0.3 | )
Balance at December 31 | $ | 5.8 |  |  | $ | 5.6 |  |  | $ | 4.9 |
We had accumulated interest and penalties associated with these unrecognized tax benefits of $6.1 million at December 31, 2016, $5.5 million at December 31, 2015, and $5.3 million at December 31, 2014. We additionally had a deferred tax asset of $4.2 million at December 31, 2016, $4.0 million at December 31, 2015, and $3.6 million at December 31, 2014, related to these balances. The net of the unrecognized tax benefits, associated interest, penalties, and deferred tax asset was $7.7 million at December 31, 2016, $7.1 million at December 31, 2015, and $6.6 million at December 31, 2014, which if resolved favorably (in whole or in part) would reduce our effective tax rate. The unrecognized tax benefits, associated interest, penalties, and deferred tax asset are included as components of Other Liabilities and Deferred Income Taxes in the Consolidated Balance Sheets. It is our policy to account for interest and penalties associated with income tax obligations as a component of income tax expense. We recognized $0.4 million during 2016, $0.4 million during 2015, and $0.3 million during 2014 (each net of tax effect), of interest and penalties as part of the provision for income taxes in the Consolidated Statements of Income. We do not expect that our unrecognized tax benefits will significantly increase or decrease during the twelve months beginning January 1, 2017.
