million and $15.4 million, respectively for the year ended December 31, 2013. Any other changes in management's estimates could have a significant impact on our future results of operations.

The content library is stated at the lower of unamortized cost or net realizable value. Streaming content licenses (whether capitalized or not) are reviewed in aggregate at the geographic region level for impairment when an event or change in circumstances indicates a change in the expected usefulness of the content. The level of geographic aggregation is determined based on the streaming content rights which are generally specific to a geographic region inclusive of several countries (such as Latin America). No material write down from unamortized cost to a lower net realizable value was recorded in any of the periods presented.

We have entered into certain licenses with performing rights organizations ("PROs"), and are currently involved in negotiations with other PROs, that hold certain rights to music and other entertainment works "publicly performed" in connection with streaming content into various territories. Accruals for estimated royalties are recorded and then adjusted based on any changes in estimates. These amounts are included in the streaming content obligations. The results of these negotiations are uncertain and may be materially different from management's estimates.

Income Taxes

We record a provision for income taxes for the anticipated tax consequences of our reported results of operations using the asset and liability method. Deferred income taxes are recognized by applying enacted statutory tax rates applicable to future years to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases as well as net operating loss and tax credit carryforwards. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The measurement of deferred tax assets is reduced, if necessary, by a valuation allowance for any tax benefits for which future realization is uncertain.

Although we believe our assumptions, judgments and estimates are reasonable, changes in tax laws or our interpretation of tax laws and the resolution of any tax audits could significantly impact the amounts provided for income taxes in our consolidated financial statements.

In evaluating our ability to recover our deferred tax assets, in full or in part, we consider all available positive and negative evidence, including our past operating results, and our forecast of future earnings, future taxable income and prudent and feasible tax planning strategies. The assumptions utilized in determining future taxable income require significant judgment and are consistent with the plans and estimates we are using to manage the underlying businesses. Actual operating results in future years could differ from our current assumptions, judgments and estimates. However, we believe that it is more likely than not that substantially all deferred tax assets recorded on our Consolidated Balance Sheets will ultimately be realized. In the
