The computation of diluted net income per common share for the three and six months ended July 3, 2011 excludes the effect of the potential exercise of stock options to purchase approximately 0.5 million and 1.0 million shares, respectively, because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the three and six months ended July 4, 2010 excludes the effect of the potential exercise of stock options to purchase approximately 4.5 million and 6.0 million shares and restricted stock units of 0.1 million and 0.4 million shares, respectively, because the effect would have been anti-dilutive.

With respect to the Teradyne's convertible debt, Teradyne intends to settle its conversion spread (i.e., the intrinsic value of the embedded option feature contained in the convertible debt) in shares. Teradyne accounts for its conversion spread using the treasury stock method. In the fourth quarter of 2010, Teradyne determined that it had the ability and intent to settle the principal amount of the convertible debt in cash, accordingly as of the fourth quarter of 2010, the principal amount has been excluded from the determination of diluted earnings per share.

Teradyne's call option on its common stock (convertible note hedge transaction) is excluded from the calculation of diluted shares because the effect would be anti-dilutive. See Note F "Debt" regarding convertible note hedge transaction.
