(12)����Income Taxes

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35 percent to 21 percent; (2) providing bonus depreciation that will allow for full expensing of qualified property; (3) creating a new limitation on deductible interest expense; (4) eliminating the corporate alternative minimum tax (“AMT”) and changing how existing AMT credits can be realized; (5) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017; (6) adding limitations on the deductibility of certain executive compensation; and (7) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years. The SEC issued guidance on accounting for the tax effects of the Tax Act. The Company must reflect the income tax effects of those aspects of the Tax Act for which the accounting is known. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements and the Tax Act provides a measurement period that should not extend beyond one year from the Tax Act enactment date. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply the tax laws that were in effect immediately before the enactment of the Tax Act.

��

The corporate rate reduction was applied to our inventory of deferred tax assets and deferred tax liabilities which resulted in the net tax benefit in the period ended December 31, 2017. The Company has determined a reasonable estimate for these amounts, and based on a continued analysis of the estimates and further guidance and interpretations on the application of the law, additional revisions may occur, and may be material, throughout the allowable measurement period.

Income tax benefit (expense) consists of:

The following table presents a summary of our domestic and foreign earnings from continuing operations before income taxes:

��

��

Income tax benefit (expense) differs from the amounts computed by applying the U.S. federal income tax rate of 35% as a result of the following:

��

��

For the year ended December 31, 2017 the significant reconciling items are net tax benefits for the effect of the change in the U.S. federal corporate tax rate from 35% to 21% on deferred taxes, the tax-free consolidation of our equity method investment in HSNi, and tax benefits derived from Liberty’s alternative energy tax credits and incentives, partially offset by net tax expense for an increase in the Company’s valuation allowance and an increase in the Company’s state effective tax rate used to measure deferred taxes.����

��

The Company has also evaluated the impact of the one-time mandatory repatriation provision of the Tax Act. Under that provision, earnings and profits of certain of the Company’s foreign subsidiaries not previously subjected to US tax could be subjected to US tax in 2017 at reduced rates. The Tax Act allows that earnings and profits deficits of certain subsidiaries may be used to offset the surpluses in others in computing the amount subject to the tax under the mandatory repatriation provision. The Company has performed an evaluation of its earnings and profits of its foreign subsidiaries and estimates that deficits in some of the subsidiaries offset the surpluses in others so that no amount is subject to the mandatory repatriation provision of the Tax Act.

��

Income tax expense was lower than the U.S. statutory tax rate of 35% in 2016 due to tax benefits derived from Liberty’s alternative energy tax credits and incentives. Income tax expense was lower than the U.S. statutory tax rate of 35% in 2015 due to the receipt of taxable dividends that are subject to a dividends received deduction.

The tax effects of temporary differences that give rise to significant portions of the deferred income tax assets and deferred income tax liabilities are presented below:

��

��

The Company's valuation allowance increased $101 million in 2017.����The entire change in valuation allowance affected tax expense and is primarily the result of new provisions in the Tax Act that changed the Company’s judgment with respect to the future utilization of its foreign tax credit carryforward.

��

At December 31, 2017, the Company had net operating losses (on a tax effected basis), federal business tax credits and foreign tax credit carryforwards for income tax purposes aggregating approximately $160 million, $31 million and $98��million, respectively, which will begin to expire in 2017 and beyond if not utilized to reduce domestic, state or foreign income tax liabilities in future periods.����The net operating losses are expected to be utilized prior to expiration, except for $67 million. The federal business tax credits are expected to be utilized prior to expiration.����As a result of the international provisions in the Tax Act, the Company estimates that $98 million of its foreign tax credit carryforward will expire without utilization.

��

A reconciliation of unrecognized tax benefits is as follows:

��

��

As of December��31, 2017, ��2016 and 2015, the Company had recorded tax reserves of $71 million, $72 million and $104 million, respectively, related to unrecognized tax benefits for uncertain tax positions.����If such tax benefits were to be recognized for financial statement purposes, $60 million, $50 million and $47 million for the years ended December 31, 2017, ��2016 and 2015, respectively, would be reflected in the Company's tax expense and affect its effective tax rate.����Liberty's estimate of its unrecognized tax benefits related to uncertain tax positions requires a high degree of judgment. The Company has tax positions for which the amount of related unrecognized tax benefits could change during 2018. The amount of unrecognized tax benefits related to these issues could change as a result of potential settlements, lapsing of statute of limitations and revisions of estimates.����It is reasonably possible that the amount of the Company's gross unrecognized tax benefits may decrease within the next twelve months by up to $3 million.

��

As of December��31, 2017, the Company's tax years prior to 2014 are closed for federal income tax purposes, and the IRS has completed its examination of the Company's 2014 tax year.��The Company's 2015, 2016 and 2017 tax years are being examined currently as part of the IRS's Compliance Assurance Process ("CAP") program.�� Various states are currently examining the Company's prior years state income tax returns.�� Certain QVC subsidiaries are currently under audit in Germany for 2012 through 2014.����������

The Company recorded $17 million of accrued interest and penalties related to uncertain tax positions as of each of December 31, 2017, 2016 and 2015.
