(a) For the years ended December 31, 2017, 2016 and 2015, Cable Communications segment revenue was derived from the following sources:

	2017		2016		2015
Residential:
Video	44.0	%	44.7	%	45.9	%
High-speed Internet	28.1	%	27.0	%	26.6	%
Voice	6.5	%	7.1	%	7.7	%
Business services	11.8	%	11.0	%	10.1	%
Advertising	4.3	%	4.9	%	4.7	%
Other	5.3	%	5.3	%	5.0	%
Total	100.0	%	100.0	%	100.0	%

Subscription revenue received from residential customers who purchase bundled services at a discounted rate is allocated proportionally to each cable service based on the individual service’s price on a stand-alone basis.

For 2017, 2.7% of Cable Communications revenue was derived from franchise and other regulatory fees. For both 2016 and 2015, 2.8% of Cable Communications revenue was derived from franchise and other regulatory fees.

(b) NBCUniversal Headquarters and Other activities include costs associated with overhead, allocations, personnel costs and headquarter initiatives.

(c) Included in Eliminations are transactions that our segments enter into with one another. The most common types of transactions are the following:

• our Cable Networks segment generates revenue by selling programming to our Cable Communications segment, which represents a substantial majority of the revenue elimination amount

• our Broadcast Television segment generates revenue from the fees received under retransmission consent agreements with our Cable Communications segment

• our Cable Communications segment generates revenue by selling advertising and by selling the use of satellite feeds to our Cable Networks segment

• our Filmed Entertainment and Broadcast Television segments generate revenue by licensing content to our Cable Networks segment; for segment reporting, this revenue is recognized as the programming rights asset for the licensed content is amortized based on third party revenue

(d) Corporate and Other activities include costs associated with overhead and personnel, revenue and expenses associated with other business development initiatives, including our new wireless phone service, and the operations of Comcast Spectacor, which owns the Philadelphia Flyers and the Wells Fargo Center arena in Philadelphia, Pennsylvania and operates arena management-related businesses.

(e) The revenue and operating costs and expenses associated with our broadcast of the 2016 Rio Olympics were reported in our Cable Networks and Broadcast Television segments. The revenue and operating costs and expenses associated with our broadcast of the 2015 Super Bowl were reported in our Broadcast Television segment.

(f) Revenue from customers located outside of the United States, primarily in Europe and Asia, in 2017, 2016 and 2015 was $7.8 billion, $6.5 billion and $5.8 billion, respectively. No single customer accounted for a significant amount of revenue in any of the periods presented.

(g) We use Adjusted EBITDA as the measure of profit or loss for our operating segments. Adjusted EBITDA is defined as net income attributable to Comcast Corporation before net (income) loss attributable to noncontrolling interests and redeemable subsidiary preferred stock, income tax benefit (expense), total other income (expense), depreciation and amortization expense, and other operating gains, and excluding impairment charges related to fixed and intangible assets and gains or losses on the sale of long-lived assets, if any. From time to time we may exclude from Adjusted EBITDA the impact of events, gains, losses or other charges (such as significant legal settlements) that affect the period-to-period comparability of our operating performance. This measure eliminates the significant level of noncash depreciation and amortization expense that results from the capital-intensive nature of certain of our businesses and from intangible assets recognized in business combinations. Additionally, it is unaffected by our capital and tax structures and by our investment activities. We use this measure to evaluate the operating performance of our operating segments and to allocate resources and capital to our operating segments. It is also a significant performance measure in our annual incentive compensation programs. We believe that this measure is useful to investors because it is one of the bases for comparing our operating performance with that of other companies in our industries, although our measure may not be directly comparable to similar measures used by other companies. This measure should not be considered a substitute for operating income (loss), net income (loss), net income (loss) attributable to Comcast Corporation, net cash provided by operating activities, or other measures we have reported in accordance with GAAP. Our reconciliation of the aggregate amount of Adjusted EBITDA for our reportable segments to consolidated income before income taxes is presented in the table below.

Year ended December 31 (in millions)	2017			2016			2015
Adjusted EBITDA	$	28,062		$	26,417		$	24,678
Adjustment for legal settlement	(250		)	—			—
Depreciation	(7,914		)	(7,464		)	(6,781		)
Amortization	(2,353		)	(2,094		)	(1,899		)
Other operating gains	442			—			—
Total other income (expense)	(2,665		)	(2,506		)	(2,626		)
Income before income taxes	$	15,322		$	14,353		$	13,372
