(1) Incremental shares from assumed conversion of the convertible notes for the three and nine months ended September 29, 2013 and September 30, 2012 are calculated using the difference between the average Teradyne stock price for the period and the conversion price of $5.48, multiplied by the 34.7 million shares that would be issued upon conversion. The result of this calculation, representing the total intrinsic value of the convertible debt, is divided by the average Teradyne stock price for the period.
(2) Convertible note hedge warrant shares for the three and nine months ended September 29, 2013 and September 30, 2012 are calculated using the difference between the average Teradyne stock price for the period and the warrant price of $7.67, multiplied by the 34.7 million shares that would be issued upon conversion. The result of this calculation, representing the total intrinsic value of the warrant, is divided by the average Teradyne stock price for the period.
