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), restricted stock (including shares held by AMC Networks and Madison Square Garden employees) and restricted stock units.

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

	Three Months		Six Months		Three Months		Six Months
	Ended June 30, 2011				Ended June 30, 2010
	(in thousands)
Basic weighted average shares outstanding		278,303		280,203		295,762		294,828
Effect of dilution:
Stock options		3,273		3,334		3,106		3,241
Restricted stock awards		4,578		5,137		5,046		5,304
Diluted weighted average shares outstanding		286,154		288,674		303,914		303,373

Anti-dilutive shares (options whose exercise price exceeds the average market price of Cablevision's common stock during the period) totaling approximately 7,500 and 11,229 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 six months ended June 30, 2011, respectively. For the three and six months ended June 30, 2010, anti-dilutive shares of 330,889 and 360,220 (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, 331,200 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 six months ended June 30, 2011 and 2010, respectively, as the performance criteria on these awards has not yet been satisfied.
