NOTE 5.

NET INCOME PER SHARE ATTRIBUTABLE TO STOCKHOLDERS

Cablevision

Basic net income per common share attributable to Cablevision stockholders is computed by dividing net income attributable to Cablevision stockholders by the weighted average number of common shares outstanding during the period. Diluted net income per common share attributable to Cablevision stockholders reflects the dilutive effects of stock options (including those held by AMC Networks and Madison Square Garden employees) and restricted stock (including shares held by AMC Networks and Madison Square Garden employees).

A reconciliation of the denominator of the basic and diluted net income per share attributable to Cablevision stockholders calculation for the three and nine months ended September 30, 2011 and 2010 is as follows:

	Three Months		Nine Months		Three Months		Nine Months
	Ended September 30, 2011				Ended September 30, 2010
	(in thousands)
Basic weighted average shares outstanding		275,145		278,498		293,671		294,438
Effect of dilution:
Stock options		3,485		3,385		3,031		3,170
Restricted stock awards		5,483		5,254		5,441		5,350
Diluted weighted average shares outstanding		284,113		287,137		302,143		302,958

Anti-dilutive shares (options whose exercise price exceeds the average market price of Cablevision's common stock during the period) totaling approximately 100,000 and 41,145 shares (which include Company options held by AMC Networks and Madison Square Garden employees), have been excluded from diluted weighted average shares outstanding for the three and nine months ended September 30, 2011, respectively. For the three and nine months ended September 30, 2010, anti-dilutive shares of 39,000 and 278,000 (which include Company options held by AMC Networks and Madison Square Garden employees), have been excluded from diluted weighted average shares outstanding, respectively. In addition, 308,900 and 913,400 and 242,401 and 689,232 restricted shares issued pursuant to the Company's employee stock plan have been excluded from the diluted weighted average shares outstanding for the three and nine months ended September 30, 2011 and 2010, respectively, as the performance criteria on these awards have not yet been satisfied.
