Included in the total UTP liability on January 31, 2017 were estimated accrued interest of $30 thousand and penalties of $16 thousand and on January 31, 2016, accrued interest was $28 thousand and penalties were $17 thousand. These non-current income tax liabilities are recorded in other long-term liabilities in the consolidated balance sheets. The Company's policy is to include interest and penalties in income tax expense. On January 31, 2017, the Company did not anticipate any significant adjustments to its unrecognized tax benefits within the next twelve months. Included in the balance on January 31, 2017 were amounts offset by deferred taxes (i.e., temporary differences) or amounts that could be offset by refunds in other taxing jurisdictions (i.e., corollary adjustments). Thus, $1.3 million of the amount accrued on January 31, 2017 would impact the ETR, if reversed.
