April 1, 2018,
there was
$309
of total unrecognized compensation cost related to outstanding stock options, which is expected to be recognized over a weighted average period of

FASB’s guidance for share-based payments requires cash flows from excess tax benefits to be classified as a part of cash flows from financing activities. Excess tax benefits are realized tax benefits from tax deductions for exercised stock options in excess of the deferred tax asset attributable to stock compensation costs for such stock options. We did
not
record any excess tax benefits in the
first
three
months of
2018
or
2017.
 
Cash received from stock option exercises under our stock-based compensation plans for the
three
-month periods ended
April 1, 2018
and
April 2, 2017
was
$939
and
$741,
respectively.
 
In
January 2018,
17,500
shares of restricted stock were awarded to certain of our employees. These shares vest in equal annual installments over
three
years. The weighted average grant date fair value of these awards was
$7.16
per share. Unrecognized compensation cost related to these restricted shares was
$110
at
April 1, 2018.
