Included in the total UTP liability were estimated accrued interest and penalty of less than $0.1 million in both January 31, 2018 and January 31, 2017. 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, 2018, 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, 2018 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, 2018 would impact the ETR, if reversed.
