Stock Based Compensation
 
The Company recorded stock based compensation expense of $
36
thousand and
$37
thousand for the years to date
March
31,
2017
and
2016,
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
2017
or
2016.
Compensation expense is charged to income ratably over the vesting period and was
$18
thousand and
$19
thousand for the year to date
March
31,
2017
and
March
31,
2016,
respectively. As of
March
31,
2017,
there was
$194
thousand of total unrecognized compensation cost related to nonvested stock options granted under the Plan. The cost will be recognized over the next
2.75
years.  At the discretion of the Board of Directors, the stock option plan was not modified for the
4%
stock dividend distributed on
July
11,
2016.

The aggregate intrinsic value of a stock option in the table above represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had
all option holders exercised their options on
March
31,
2017.
 
In
2009,
the
Board of Directors authorized
132,000
shares of common stock for issuance under the Restricted Stock Plan. On

2016,
a
4%
stock dividend was distributed and added
5,280
to the total number of shares authorized for issuance and currently raising the total available to
137,280.
The plan provides for restricted stock awards to key employees. Restricted shares awarded to employees generally vest over a
five
year period and compensation expense is charged to income ratably over the vesting period and was
$
18
thousand for the years to date
March
31,
2017
and
2016.
Compensation is accounted for using the fair market value of the Company’s common stock on the date the restricted shares are awarded. The Company granted
8,258
and
11,149*
shares of restricted stock under the plan during the years to date
March
31,
2017
and
March
31,
2016,
respectively. The weighted-average grant date fair value of restricted stock granted in
20176
was
$9.87
compared to
$9.09*
in
2016.
  
 
As of
March
31,
2017,
there was
$228
thousand of total unrecognized compensation cost related to restricted stock granted under the Plan. The cost is expected to be recognized through
