Share-Based Payments
 
Employee Stock Option Plans
 
The Company’s share-based incentive plans offering stock options primarily consists of
two
plans. Under both plans,
one
new share is issued for each stock option exercised. The plans are described below.
 
The Company’s
1998
Incentive Plan (the
“1998
Plan”) was the Company’s primary plan through
November 2007.
Under this plan shares of common stock was made available for issuance to employees and directors. Through
December 1999,
1,066,000
options were granted that would cliff vest after
9.8
years; however, such vesting was accelerated for
637,089
of these options upon meeting certain earnings per share goals through the fiscal year ended
June 30, 2003.
Subsequent to
December 1999
and through
June 2002,
1,248,250
options were granted that would cliff vest after
6.0
years; however, such vesting was accelerated for
300,494
of these options upon meeting certain earnings per share goals through the fiscal year ended
June 30, 2005.
The Company’s
2007
Equity Incentive Plan (the
“2007
Plan”) was restated and approved by the shareholders on
December 12, 2016.
Provisions of the restated
2007
Plan include the granting of up to
2,000,000
incentive and non-qualified stock options, stock appreciation rights, restricted stock and restricted stock units. Options
may
be granted to employees, officers, non-employee directors and other service providers and
may
be granted upon such terms as the Compensation Committee of the Board of Directors determines in their sole discretion.
 
Of the options granted subsequent to
June 2002,
all vesting schedules are based on
3
or
4
-year vesting schedules, with either
one
-
third
or
one
-
fourth
vesting on the
first
anniversary and the remaining options vesting ratably over the remainder of the vesting term. Generally, directors and officers have
3
-year vesting schedules and all other employees have
4
-year vesting schedules. Additionally, in the event of a change in control or the occurrence of a corporate transaction, the Company’s Board of Directors has the authority to elect that all unvested options shall vest and become exercisable immediately prior to the event or closing of the transaction. All options outstanding as of
December 31, 2017
had contractual lives of
ten
years.
 
Under the
1998
Plan,
2,500,000
shares were authorized for grant. As of
December 31, 2017,
there were
no
options outstanding under the
1998
Plan.
 
As of
December 31, 2017,
there were
764,430
options outstanding under the
2007
Plan. As of
December 31, 2017,
the
2007
Plan had
774,456
authorized unissued options, while there were
no
options remaining that could be granted under the
1998
Plan.
 
The Company uses judgment in determining the fair value of the share-based payments on the date of grant using an option-pricing model with assumptions regarding a number of highly complex and subjective variables. These variables include, but are
not
limited to, the risk-free interest rate of the awards, the expected life of the awards, the expected volatility over the term of the awards, and the expected dividends of the awards. The Company uses the Black-Scholes option pricing model to determine the fair value of share-based payments granted under the guidelines of ASC Topic
718.
 
In applying the Black-Scholes methodology to the options granted, the Company used the following assumptions:

2015
 
Risk-free interest rate, average

44.30
%
Expected dividend yield
   
2.83
%
   
1.71
%
   
1.10
%
 
 
The risk-free interest rate is determined using the U.S. Treasury rate in effect as of the date of the grant, based on the expected life of the stock option. The expected life of the stock option is determined using historical data.
 
The expected price volatility is determined using a weighted average of daily historical volatility of the Company’s stock price over the corresponding expected option life.
 
Under guidelines of ASC Topic
718,
the Company recognizes the associated compensation cost for only those awards expected to vest on a straight-line basis over the underlying requisite service period. The Company estimated the forfeiture rates based on its historical experience and expectations about future forfeitures.

Employee Stock Purchase Plan
 
During
2017,
the Company issued shares to employees under the Company’s
2016
Employee Stock Purchase Plan (the “ESPP”). The ESPP was approved by the Company’s shareholders on
December 12, 2016.
As of
December 31, 2017,
466,783
of the originally approved
500,000
shares were available for offerings under the ESPP. Offering periods under the ESPP commence on each
Jan 1
and
July 1,
and continue for a duration of
six
months. The ESPP is available to all employees who do
not
own, or are deemed to own, shares of stock making up an excess of
5%
of the combined voting power of the Company, its parent or subsidiary.
 
During each offering period, each eligible employee
may
purchase shares under the ESPP after authorizing payroll deductions. Under the ESPP, each employee
may
purchase up to the lesser of
2,500
shares or
$25
of fair market value (based on the established purchase price) of the Company’s stock for each offering period. Unless the employee has previously withdrawn from the offering, his or her accumulated payroll deductions will be used to purchase common stock on the last business day of the period at a price equal to
85%
(or a
15%
discount) of the fair market value of the common stock on the
first
or last day of the offering period, whichever is lower.

Stock Repurchase Program and Cash Dividends
 
In
May 2012,
our Board of Directors authorized a stock repurchase program to purchase the Company’s common stock in the open market. A total of
272,767
shares costing
$2,598
were purchased under this program during the year ended
December 31, 2014.
The cost of shares purchased were recorded as a reduction to shareholders’ equity. On
December 2, 2016,
the Company announced the discontinuance of the stock repurchase program along with the initiation of a cash dividend plan.
 
On
March 9, 2016,
the Board of Directors of the Company authorized the repurchase of up to
$10
million of the Company’s outstanding shares of common stock under a new stock repurchase program. In connection with the repurchase authorization, the Company was authorized to complete the repurchase through open market transactions or through an accelerated share repurchase program, in each case to be executed at management’s discretion based on business and market conditions, stock price, trading restrictions, acquisition activity and other factors. The repurchase program
may
be suspended or discontinued at any time without prior notice. The transactions effectuated to date occurred in open market purchases.
 
On 
March 
1,
2017,
the Board of Directors of the Company renewed and extended the repurchase program for up to an additional
$10
million of common stock over the next
twelve
months. In connection with the repurchase extension authorization, the Company was authorized to complete the repurchase through open market transactions or through an accelerated share repurchase program, in each case to be executed at management’s discretion based on business and market conditions, stock price, trading restrictions, acquisition activity and other factors. The repurchase program
may
be suspended or discontinued at any time without prior notice. The transactions effectuated to date occurred in open market purchases. This program terminated in
March 2018.
 
During the
twelve
months ended
December 31, 2017,
we acquired the following shares of common stock under the stock repurchase program authorized by the Board of Directors in
March 2016
and renewed and extended in
March 2017:
