(

8

) Share Repurchase Program

In

December 2007,

our Board of Directors approved and we announced a share repurchase program to repurchase up to

one million

shares of our common stock either through purchases on the open market or through private transactions and in accordance with Rule

10b

-

18

of the Exchange Act. In

November 2015,

our Board of Directors approved and we announced an increase in the share repurchase program, providing for the repurchase of up to

$40

million, or approximately

two million

shares, of our common stock, which was increased by our Board of Directors to

3.3

million shares on

August 15, 2017

to reflect the

five

-for-

three

stock split effected in the form of a stock dividend on

July 7, 2017.

The timing and extent to which we repurchase shares depends on market conditions and other corporate considerations. The repurchase program does

not

have an expiration date.

We did

not

repurchase any shares in

2017

or in the

first

three

months of

2018.

As of

March 31, 2018,

future repurchases of up to

$16.3

million, or

1.0

million shares, were available in the share repurchase program.
