FAIR VALUE MEASUREMENT

12 Months Ended

Dec. 31, 2015

The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect a reporting entity's pricing based upon their own market assumptions. The fair value hierarchy consists of the following three levels:


•	Level I - Quoted prices for identical instruments in active markets.


•	Level II - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.


•	Level III - Instruments whose significant value drivers are unobservable.

The following table presents for each of these hierarchy levels, the Company's financial assets and financial liabilities that are measured at fair value on a recurring basis at December 31, 2015 and December 31, 2014:



	At December 31, 2015
	Level I		Level II		Level III		Total
Assets:

Money market funds	$	922,765	$	—	$	—	$	922,765
Investment securities	130		—		—		130
Investment securities pledged as collateral	1,211,982		—		—		1,211,982
Prepaid forward contracts	—		82,408		—		82,408
Liabilities:
Prepaid forward contracts	—		2,706		—		2,706



	At December 31, 2014
	Level I		Level II		Level III		Total
Assets:

Money market funds	$	736,330	$	—	$	—	$	736,330
Investment securities	132		—		—		132
Investment securities pledged as collateral	1,245,916		—		—		1,245,916
Prepaid forward contracts	—		7,317		—		7,317
Liabilities:
Prepaid forward contracts	—		102,217		—		102,217

The Company's cash equivalents, investment securities and investment securities pledged as collateral are classified within Level I of the fair value hierarchy because they are valued using quoted market prices.

The Company's prepaid forward contracts reflected as derivative contracts and liabilities under derivative contracts in the Company's balance sheets are valued using market-based inputs to valuation models. These valuation models require a variety of inputs, including contractual terms, market prices, yield curves, and measures of volatility. When appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads and credit risk considerations. Such adjustments are generally based on available market evidence. Since model inputs can generally be verified and do not involve significant management judgment, the Company has concluded that these instruments should be classified within Level II of the fair value hierarchy.

The Company considers the impact of credit risk when measuring the fair value of its derivative asset and/or liability positions, as applicable.

In addition, see Note 4 for a discussion of impairment charges related to nonfinancial assets not measured at fair value on a recurring basis.

Fair Value of Financial Instruments

The following methods and assumptions were used to estimate fair value of each class of financial instruments for which it is practicable to estimate:

Credit Facility Debt, Collateralized Indebtedness, Senior Notes and Debentures and Notes Payable

The fair values of each of the Company's debt instruments are based on quoted market prices for the same or similar issues or on the current rates offered to the Company for instruments of the same remaining maturities. The fair value of notes payable is based primarily on the present value of the remaining payments discounted at the borrowing cost.

The carrying values, estimated fair values, and classification under the fair value hierarchy of the Company's financial instruments, excluding those that are carried at fair value in the accompanying consolidated balance sheets, are summarized as follows:



		December 31, 2015
	Fair Value Hierarchy	Carrying Amount		Estimated Fair Value
CSC Holdings notes receivable:
Cablevision senior notes held by Newsday Holdings LLC (a)	Level II	$	611,455	$	616,020

Debt instruments:
Credit facility debt (b)	Level II	$	2,521,942	$	2,525,654
Collateralized indebtedness	Level II	1,191,324		1,176,396
Senior notes and debentures	Level II	3,065,092		2,996,440
Notes payable	Level II	14,544		14,483
CSC Holdings total debt instruments		6,792,902		6,712,973

Cablevision senior notes	Level II	2,795,550		2,760,168
Cablevision total debt instruments		$	9,588,452	$	9,473,141

CSC Holdings notes receivable:
Cablevision senior notes held by Newsday Holdings LLC (a)	Level II	$	611,455	$	680,587

Debt instruments:
Credit facility debt (b)	Level II	$	2,780,649	$	2,785,975
Collateralized indebtedness	Level II	986,183		957,803
Senior notes and debentures	Level II	3,062,126		3,368,875
Notes payable	Level II	23,911		23,682

Cablevision senior notes	Level II	2,793,741		3,048,387
Cablevision total debt instruments		$	9,646,610	$	10,184,722


(a)	These notes are eliminated at the consolidated Cablevision level.


(b)	The principal amount of the Company's credit facility debt, which bears interest at variable rates, approximates its fair value.

Fair value estimates related to the Company's debt instruments and senior notes receivable presented above are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates are subjective in nature and involve uncertainties and matters of significant judgments and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.
