indicated that the estimated fair value of our cable franchise rights exceeded the carrying value (“headroom”) for each of our units of accounts by a significant amount (see table below).
Given the significant headroom that existed on July 1, 2008, we do not believe the current economic environment, regulatory changes, or the decline in our market capitalization since our July 1 testing, represent events or changes in circumstances that are indicative of an impairment of value at December 31, 2008.
The table below illustrates the impairment related to our various cable divisions that would have occurred had the hypothetical reductions in fair value existed at the time of our last annual impairment testing.
## Table 0 ##
Income Taxes Our provision for income taxes is based on our current period income, changes in deferred income tax assets and liabilities, income tax rates, changes in estimates of our uncertain tax positions, and tax planning opportunities available in the jurisdictions in which we operate.
We prepare and file tax returns based on our interpretation of tax laws and regulations, and we record estimates based on these judgments and interpretations.
On January 1, 2007, we adopted Financial Accounting Standards Board (“FASB”) Interpretation (“FIN”) No.48, “Accounting for Uncertainty in Income Taxes – an Interpretation of FASB Statement No.109,” (“FIN 48”).
We evaluate our tax positions using the recognition threshold and the measurement attribute in accordance with this interpretation.
From time to time, we engage in transactions in which the tax consequences may be subject to uncertainty.
Examples of these transactions include business acquisitions and disposals, including consideration paid or received in connection with these transactions, and certain financing transactions.
Significant judgment is required in assessing and estimating the tax consequences of these transactions.
We determine whether it is more likely than not that a tax position will be sustained on examination, including the resolution of any related appeals or litigation processes, based on the technical merits of the position.
In evaluating whether a tax position has met the more-likely-than-not recognition threshold, we presume that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information.
A tax position that meets the more-likely-than-not recognition threshold is measured to determine the amount of benefit to be recognized in the financial statements.
The tax position is measured at the largest amount of benefit that has a greater than 50% likelihood of being realized when the position is ultimately resolved.
We adjust our estimates periodically because of ongoing examinations by and settlements with the various taxing authorities, as well as changes in tax laws, regulations and precedent.
The effects on our financial statements of income tax uncertainties that arise in connection with business combinations and those associated with entities acquired in business combinations are discussed in Note 2 to our consolidated financial statements.
We believe that adequate accruals have been made for income taxes.
When uncertain tax positions are ultimately resolved, either individually or in the aggregate, differences between our estimated amounts and the actual amounts are not expected to have a material adverse effect on our consolidated financial position but could possibly be material to our consolidated results of operations or cash flow for any one period.
Interest payments increased in 2015 primarily due to a higher level of debt outstanding.
Interest payments remained relatively flat in 2014.
The increase in income tax payments in 2015 was primarily due to higher taxable income from operations offset by the timing of certain tax deductions.
The decrease in income tax payments in 2014 was primarily due to the settlement of tax disputes and the repatriation of foreign earnings in 2013.
The decrease was partially offset by higher taxable income from operations and the net impact of the economic stimulus legislation in 2014.
We expect income tax payments to increase in 2016 primarily due to higher taxable income from operations.
Investing Activities Net cash used in investing activities in 2015 consisted primarily of cash paid for capital expenditures, intangible assets, acquisitions and the purchases of investments, which was partially offset by proceeds from the sales of businesses and investments.
Net cash used in investing activities in 2014 consisted primarily of cash paid for capital expenditures and intangible assets.
Net cash used in investing activities in 2013 consisted primarily of cash paid for capital expenditures, acquisitions and construction of real estate properties, purchases of investments, and cash paid for intangible assets.
Capital Expenditures Our most significant recurring investing activity has been capital expenditures in our Cable Communications segment, and we expect that this will continue in the future.
The table below summarizes the capital expenditures we incurred in our Cable Communications segment in 2015, 2014 and 2013.
## Table 1 ##
Cable Communications capital expenditures increased in 2015 and 2014 primarily due to increased spending on customer premise equipment related to our X1 platform and wireless gateways, our continued investment in network infrastructure to increase network capacity, increased investment in support capital as we expand our cloud-based initiatives, and our continued investment to expand business services.
Capital expenditures in our NBCUniversal segments increased 13.5% to $1.4 billion in 2015 and 5.3% to $1.2 billion in 2014 primarily due to continued investment in our Universal theme parks, including a purchase of land in 2015.
Our capital expenditures for 2016 are focused on the continued deployment of our X1 platform and Cloud DVR technology, acceleration of wireless gateways, network infrastructure to increase network capacity, and the expansion of business services.
Capital expenditures for subsequent years will depend on numerous factors, including acquisitions, competition, changes in technology, regulatory changes, the timing and rate of deployment of new services, and the capacity required for existing services.
In addition, we expect to continue to invest in existing and new attractions at our Universal theme parks.
We are developing a Universal theme park in Beijing, China.
We expect the development of this park to continue in 2016.
Cash Paid for Intangible Assets In 2015, 2014 and 2013, cash paid for intangible assets consisted primarily of expenditures for software.

## Table 2 ##
Indefinite-Lived Intangible Assets Indefinite-lived intangible assets consist primarily of our cable franchise rights, as well as trade names and FCC licenses.
Our cable franchise rights represent the values we attributed to agreements with state and local authorities that allow access to homes and businesses in cable service areas acquired in business combinations.
We do not amortize our cable franchise rights because we have determined that they meet the definition of indefinite-lived intangible assets since there are no legal, regulatory, contractual, competitive, economic or other factors which limit the period over which these rights will contribute to our cash flows.
We reassess this determination periodically or whenever events or substantive changes in circumstances occur.
Costs we incur in negotiating and renewing cable franchise agreements are included in other intangible assets and are generally amortized on a straight-line basis over the term of the franchise agreement.
We assess the recoverability of our cable franchise rights and other indefinite-lived intangible assets annually, or more frequently whenever events or substantive changes in circumstances indicate that the assets might be impaired.
Our three Cable Communications divisions represent the unit of account we use to test for impairment for our cable franchise rights.
We evaluate the unit of account used to test for impairment of our cable franchise rights and other indefinite-lived intangible assets periodically or whenever events or sub- stantive changes in circumstances occur to ensure impairment testing is performed at an appropriate level.
The assessment of recoverability may first consider qualitative factors to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount.
A quantitative assessment is performed if the qualitative assessment results in a more-likely-than-not determination or if a qualitative assessment is not performed.
When performing a quantitative assessment, we estimate the fair value of our cable franchise rights and other indefinite-lived intangible assets primarily based on a discounted cash flow analysis that involves significant judgment.
When analyzing the fair values indicated under the dis- counted cash flow models, we also consider multiples of operating income before depreciation and amortization generated by the underlying assets, current market transactions, and profitability information.
If the fair value of our cable franchise rights or other indefinite-lived intangible assets were less than the carrying amount, we would recognize an impairment charge for the difference between the estimated fair value and the carrying value of the assets.
Unless presented separately, the impairment charge is included as a compo- nent of amortization expense.
We did not recognize any material impairment charges in any of the periods presented.
