6.	Employee Stock Benefit Plans

Our

2005

Equity Incentive Plan (the

“2005

Plan”) is a broad-based, long-term retention program intended to attract, motivate, and retain talented employees as well as align stockholder and employee interests. Awards that

may

be granted under the program include, but are

not

limited to, non-qualified and incentive stock options, restricted stock units, and performance stock units. We settle employee stock option exercises, employee stock purchase plan purchases, and the vesting of restricted stock units, and performance stock units with newly issued common shares. At

September 28, 2019,

there were

2,507,028

shares available for future equity grants under the

2005

Plan.

Stock Options

Stock options

may

be granted to employees, consultants and non-employee directors to purchase a fixed number of shares of our common stock. The exercise prices of options granted are at least equal to the fair market value of our common stock on the dates of grant and options vest and become exercisable in annual increments that range from

one

four

years from the date of grant. Stock options granted under the

2005

Plan have a maximum contractual term of

ten

years. In the

first

nine

months of fiscal

2019

we did

not

grant any stock options and we issued

36,650

shares of our common stock on the exercise of options that were granted previously.

September 28, 2019,

we had

368,276

stock options exercisable and outstanding. These options had a weighted-average exercise price of

$10.34

per share, an aggregate intrinsic value of approximately

$1.2

million and the weighted average remaining contractual term was approximately

3.0

years.

Restricted Stock Units

We grant restricted stock units (“RSUs”) to certain employees, consultants and directors. RSUs vest in annual increments that range from

one

four

years from the date of grant. Prior to vesting, RSUs do

not

have dividend equivalent rights, do

not

have voting rights and the shares underlying the RSUs are

not

considered issued and outstanding. New shares of our common stock will be issued on the date the RSUs vest net of the minimum statutory tax withholding requirements to be paid by us on behalf of our employees. As a result, the actual number of shares issued will be fewer than the actual number of RSUs outstanding at

September 28, 2019.

In the

first

nine

months of fiscal

2019

we awarded

670,737

RSUs and we issued

560,795

shares of our common stock on vesting of previously granted awards. At

September 28, 2019,

we had

1,331,427

RSUs outstanding with an aggregate intrinsic value of approximately

$17.8

million and the weighted average remaining vesting period was approximately

1.4

years.

Performance Stock Units

We also grant performance stock units (“PSUs”) to senior executives as a part of our long-term equity compensation program. The number of shares of common stock that will ultimately be issued to settle PSUs granted in

2019,

2018

and

2017

ranges from

25%

200%

of the number granted and is determined based on certain performance criteria over a

three

-year measurement period. The performance criteria for the PSUs are based on a combination of our annualized Total Shareholder Return (“TSR”) for the performance period and the relative performance of our TSR compared with the annualized TSR of certain peer companies for the performance period. PSUs granted in

2019,

2018

and

2017

vest

100%

on the

third

anniversary of their grant, assuming achievement of the applicable performance criteria.

We estimated the fair value of the PSUs using a Monte Carlo simulation model on the date of grant. Compensation expense is recognized ratably over the derived service period. New shares of our common stock will be issued on the date the PSUs vest net of the minimum statutory tax withholding requirements to be paid by us on behalf of our employees. As a result, the actual number of shares issued will be fewer than the actual number outstanding at

September 28, 2019.

In the

first

nine

months of fiscal

2019,

we awarded

167,226

PSUs and we issued

35,696

shares of our common stock on vesting of previously granted awards. At

September 28, 2019,

we had

364,194

PSUs outstanding with an aggregate intrinsic value of approximately

$4.9

million and the weighted average remaining vesting period was approximately

1.6

years.

Employee Stock Purchase Plan

The Cohu, Inc.

1997

Employee Stock Purchase Plan (“the ESPP”) provides for the issuance of shares of our common stock. Under the ESPP, eligible employees

may

purchase shares of Cohu common stock through payroll deductions at a price equal to

percent of the lower of the fair market value of Cohu common stock at the beginning or end of each

-month purchase period, subject to certain limits. During the

first

nine

months of fiscal

2019,

63,998

shares of our common stock were sold to our employees under the ESPP leaving

1,034,612

shares available for future issuance.
