Stock-Based Compensation

3 Months Ended

Mar. 29, 2020

. STOCK-BASED COMPENSATION

Under Teradyne’s stock compensation plans, Teradyne grants service-based restricted stock units, performance-based restricted stock units and stock options, and employees are eligible to purchase Teradyne’s common stock through its Employee Stock Purchase Plan (“ESPP”).

Service

-based restricted stock unit awards granted to employees vest in equal annual installments over four years. Restricted stock unit awards granted to

non-employee

directors vest after a one-year period, with 100% of the award vesting on the earlier of (a) the first anniversary of the grant date or (b) the date of the following year’s Annual Meeting of Shareholders. Teradyne expenses the cost of the restricted stock unit awards subject to

service

-based vesting, which is determined to be the fair market value of the shares at the date of grant, ratably over the period during which the restrictions lapse.

Performance-based restricted stock units (“PRSUs”) granted to Teradyne’s executive officers may have a performance metric based on relative total shareholder return (“TSR”). Teradyne’s three-year TSR performance is measured against the New York Stock Exchange (“NYSE”) Composite Index. The final number of TSR PRSUs that vest will vary based upon the level of performance achieved

from 0% to 200% of the target shares capped at four times the grant date value for grants prior to 2019.

The TSR PRSUs will vest upon the three-year anniversary of the grant date. The TSR PRSUs are valued using a Monte Carlo simulation model. The number of units expected to be earned, based upon the achievement of the TSR market condition, is factored into the grant date Monte Carlo valuation. Compensation expense is recognized on a straight-line basis over the shorter of the three-year service period or the period from the grant to the date described in the retirement provisions below. Compensation expense for executive officers meeting the retirement provisions prior to the grant date is recognized during the 365 days following the grant. Compensation expense is recognized regardless of the eventual number of units that are earned based upon the market condition, provided the executive officer remains an employee at the end of the three-year period. Compensation expense is reversed if at any time during the three-year service period the executive officer is no longer an employee, subject to the retirement and termination eligibility provisions noted below.

PRSUs granted to Teradyne’s executive officers may also have a performance metric

based

three-year

cumulative

non-GAAP

profit before interest and tax (“PBIT”) as a percent of

Teradyne

’s revenue.

Non-GAAP

PBIT is a financial measure equal to GAAP income from operations less restructuring and other, net; amortization of acquired intangible assets; acquisition and divestiture related charges or credits; pension actuarial gains and losses;

non-cash

convertible debt interest expense; and other

non-recurring

gains and charges. The final number of PBIT PRSUs that vest will vary based upon the level of performance achieved from

% to

200

% of the target shares.

The PBIT PRSUs will vest upon the three-year anniversary of the grant date. Compensation expense is recognized on a straight-line basis over the shorter of the three-year service period or the period from the grant date to the date described in the retirement provisions below. Compensation expense for executive officers meeting the retirement provisions prior to the grant date is recognized during the 365 days following the grant. Compensation expense is recognized based on the number of units that are earned based upon the three-year Teradyne PBIT as a percent of Teradyne’s revenue, provided the executive officer remains an employee at the end of the three-year period subject to the retirement and termination eligibility provisions noted below.

If a PRSU recipient’s employment ends prior to the determination of the performance percentage due to (1) permanent disability or death or (2) retirement or termination other than for cause, after attaining both at least

age sixty and at least ten years of service, then all or a portion of the recipient’s PRSUs (based on the actual performance percentage achieved on the determination date) will vest on the date the performance percentage is determined. Except as set forth in the preceding sentence, no PRSUs will vest if the executive officer is no longer an employee at the end of the three-year period.

Stock options to purchase Teradyne’s common stock at 100% of the fair market value on the grant date vest in equal annual installments over four years from the grant date and have a maximum term of seven years.

During the three months ended March 29, 2020 and March 31, 2019, Teradyne granted 0.4 million and 0.6 million of service-based restricted stock unit awards to employees at a weighted average grant date fair value of $70.98 and $35.88, respectively.

During the three months ended March 29, 2020 and March 31, 2019, Teradyne granted 0.1 million of PBIT PRSUs with a grant date fair value of $70.94 and $35.67, respectively.

During the three months ended March 29, 2020 and March 31, 2019, Teradyne grante

0.1

million TSR PRSUs, with a grant date fair value of

89.93

and $

48.47

, respectively.

The fair value was estimated using the Monte Carlo simulation model with the following assumptions:


	For the Three Months Ended
	March 29,			March 31,
	2020			2019
Risk-free interest rate		1.5	%		2.6	%
Teradyne volatility-historical		34.9	%		31.8	%
NYSE Composite Index volatility-historical		11.4	%		12.0	%
Dividend yield		0.6	%		1.0	%

Expected volatility was based on the historical volatility of Teradyne’s stock and the NYSE Composite Index for the 2020 and 2019 grant over the most recent three-year period. The risk-free interest rate was determined using the U.S. Treasury yield curve in effect at the time of grant. Dividend yield was based upon an estimated annual dividend amount

of $0.40

per share divided by Teradyne’s stock price on the grant date of

72.10

for the 2020 grant and an estimated annual dividend amount of

0.36

per share divided by Teradyne’s stock price on the grant date of

36.75

for the 2019 grant.

During the three months ended March 29, 2020 and March 31, 2019, Teradyne granted 0.1

million of service-based stock options to executive officers at a weighted average grant date fair value of

20.67

and $

10.26

, respectively.

The fair value of stock options was estimated using the Black-Scholes option-pricing model with the following assumptions:


	For the Three Months Ended
	March 29,			March 31,
	2020			2019
Expected life (years)		5.0			5.0
Risk-free interest rate		1.6	%		2.6	%
Volatility-historical		31.6	%		30.1	%
Dividend yield		0.6	%		1.0	%

Teradyne determined the stock options’ expected life based upon historical exercise data for executive officers, the age of the executive officers and the terms of the stock option grant. Volatility was determined using historical volatility for a period equal to the expected life. The risk-free interest rate was determined using the U.S. Treasury yield curve in effect at the time of grant. Dividend yield was based upon an estimated annual dividend amount of $0.40

per share divided by Teradyne’s stock price on the grant date of

72.10

for the 2020 grant and an estimated annual dividend amount of $0.36 per share divided by Teradyne’s stock price on the grant date of

36.75

for the 2019 grant.
