two
executives on
August 31, 2016
at a purchase price of
$5.34
per share. Stock-based compensation expense totaling 
$2.1
 million was recognized during the
nine
months ended

for the accelerated vesting of these options in our IPO. The options have a 
ten
-year term from the grant date. The options remain outstanding and unexercised at 
September 30, 2018 
and are in-the-money.
 
Restricted Shares—
We grant restricted stock to certain senior executives, key employees and directors. The shares vest over 
one
 to 
three
 years from the date of grant. During the vesting period, the participants have voting rights and 
may 
receive dividends, but the shares 
may 
not
 be sold, assigned, transferred, pledged or otherwise encumbered. Additionally, granted but unvested shares are forfeited upon termination of employment, unless an employee enters into another written arrangement with the Company. The fair value of the restricted shares on the date of the grant is amortized ratably over the service period. Compensation expense related to these awards totaled
$0.7
million and
$1.9
million for the
three
and
nine
months ended
September 30, 2018,
respectively. The Company recognized
$
0.3
million of compensation expense for restricted share awards for the
three

nine
months ended
