NOTE 11. INCOME TAXES

Significant components of our deferred tax liabilities (assets) are as follows at December 31:

20162015
Depreciation and amortization$44,903$46,067
Licenses and nonamortizable intangibles22,89220,732
Employee benefits(10,045)(10,517)
Deferred fulfillment costs3,2042,172
Net operating loss and other carryforwards(4,304)(4,029)
Other – net(216)(1,478)
Subtotal56,43452,947
Deferred tax assets valuation allowance2,2832,141
Net deferred tax liabilities$58,717$55,088
Noncurrent deferred tax liabilities$60,128$56,181
Less: Noncurrent deferred tax assets(1,411)(1,093)
Net deferred tax liabilities$58,717$55,088

At December 31, 2016, we had combined net operating loss carryforwards (tax effected) for federal income tax purposes of $144, state of $830 and foreign of $1,981, expiring through 2032. Additionally, we had federal credit carryforwards of $0 and state credit carryforwards of $1,348, expiring primarily through 2036.

We recognize a valuation allowance if, based on the weight of available evidence, it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. Our valuation allowances at December 31, 2016 and 2015 related primarily to state and foreign net operating losses and state credit carryforwards.

We recognize the financial statement effects of a tax return position when it is more likely than not, based on the technical merits, that the position will ultimately be sustained. For tax positions that meet this recognition threshold, we apply our judgment, taking into account applicable tax laws, our experience in managing tax audits and relevant GAAP, to determine the amount of tax benefits to recognize in our financial statements. For each position, the difference between the benefit realized on our tax return and the benefit reflected in our financial statements is recorded on our consolidated balance sheets as an unrecognized tax benefit (UTB). We update our UTBs at each financial statement date to reflect the impacts of audit settlements and other resolutions of audit issues, the expiration of statutes of limitation, developments in tax law and ongoing discussions with taxing authorities. A reconciliation of the change in our UTB balance from January 1 to December 31 for 2016 and 2015 is as follows:

Federal, State and Foreign Tax20162015
Balance at beginning of year$6,898$4,465
Increases for tax positions related to the current year3181,333
Increases for tax positions related to prior years473660

Less: Tax attributable to timing items included above(3,398)(3,460)
Less: UTBs included above that relate to acquisitions that would impact goodwill
if recognized during the measurement period-(842)
Total UTB that, if recognized, would impact the
effective income tax rate as of the end of the year$3,701$3,152

Periodically we make deposits to taxing jurisdictions which reduce our UTB balance but are not included in the reconciliation above. The amount of deposits that reduced our UTB balance was $3,084 at December 31, 2016, and $3,027 at December 31, 2015.

Accrued interest and penalties included in UTBs were $1,140 as of December 31, 2016, and $1,138 as of December 31, 2015. We record interest and penalties related to federal, state and foreign UTBs in income tax expense. The net interest and penalty expense (benefit) included in income tax expense was $24 for 2016, $83 for 2015, and $(64) for 2014.

We file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. As a large taxpayer, our income tax returns are regularly audited by the Internal Revenue Service (IRS) and other taxing authorities. The IRS has completed field examinations of our tax returns through 2010. All audit periods prior to 2003 are closed for federal examination purposes. Contested issues from our 2003 through 2010 returns are at various stages of resolution with the IRS Appeals Division; we are unable to estimate the impact the resolution of these issues may have on our UTBs.

The components of income tax (benefit) expense are as follows:

Current$2,915$2,496$1,610
