. EMPLOYEE BENEFIT AND SAVINGS PLANS

We have a

401

(k) plan to provide retirement benefits for our employees. As allowed under Section

401

(k) of the Internal Revenue Code, the plan provides tax-deferred salary contributions for eligible employees and allows employees to contribute a percentage of their annual compensation to the plan on a pretax basis. Employee contributions are limited to a maximum annual amount as set periodically by the Internal Revenue Code. In

20

17,

2016,

and

2015,

we matched

100%

of the pretax employee contributions on the

first

3%

of eligible earnings and

50%

of the pretax employee contributions on the next

2%

of eligible earnings that are contributed by employees.

Year Ended December 31,	Maximum Matching Contribution per Participant *		Total Matching Contribution
20 17		$10,600		$326,612
20 16		$10,600		$277,753
20 15		$10,400		$290,388

* Due to the annual limit on eligible earnings imposed by the Internal Revenue Code

The plan allows employees who meet the age requirements and reach the plan contribution limits to make a catch-up contribution. The catch-up contributions are

not

eligible for matching contributions. In addition, the plan provides for discretionary matching contributions as determined by the Board of Directors. There were

no

discretionary mat

ching contributions made in

2017,

2016,

or

2015.

We currently offer

no

postretirement or postemployment benefits to our employees.
