Stock Based Compensation
 
The Company recorded stock-based compensation expense of
$159
thousand and
$109
thousand for the years to date
September 
30,
2018
and
2017,
respectively.
 
The
2005
Stock Option Plan (the Plan) pursuant to which the Board of Directors granted stock options to directors, officers and employees expired in
2016,
thus there are
no
options available for future issuance. Under the fair value recognition provisions of relevant accounting guidance, stock-based compensation cost was measured at the grant date based on the fair value of the award and was and continues to be recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. 
 
The Company used the Black-Scholes option pricing model to determine the fair value of stock options. The fair value of the stock based payment awards was affected by the price of the Company's stock and a number of financial assumptions and variables. These variables included the risk-free interest rate, expected dividend rate, expected stock price volatility and the expected life of the options. 
No
stock options were granted during
2018
or
2017.
Compensation expense is charged to income ratably over the vesting period and was
$53
thousand each of the years to date
September 30, 2018
and
September 30, 2017,
respectively. As of
September 30, 2018,
there was
$78
thousand of total unrecognized compensation cost related to nonvested stock options granted under the Plan. The cost will be recognized over the next
1.25
years.
