NOTE
8.
INCOME TAXES
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.
 
We had
no
unrecognized tax benefits as of
September 
30,
2019,
and we do
not
expect any significant unrecognized tax benefits within
12
 months of the reporting date. We recognize interest and penalties related to income tax matters in income tax expense. As of
September 
30,
2019
we had
no
accrued interest related to uncertain tax positions. The tax years
2016
through
2018
remain open to examination by the major taxing jurisdictions to which we are subject.
