. 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

2

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 repurchased and retired

759,302

shares of our common stock for

$7.5

million in the

first

quarter of

2016

and did

not

repurchase any shares in the

last

three

quarters of

2016

or in

2017.

In the

fourth

quarter of

2015

we repurchased and retired

1.6

million shares of our common stock for

$16.2

million.
