may

make voluntary contributions to the

401

(k) Plan up to

100%

of their annual compensation, subject to statutory annual limitations. In

2019,

2018

and

2017,

the Company made discretionary contributions under the

401

(k) Plan of

$0.4

million,

$0.4

million and

For the Company’s Japanese subsidiary, a discretionary employee retirement plan has been established. In addition, for some of the Company’s other foreign subsidiaries, the Company deposits funds with insurance companies,

third
