Schedule of Unrecognized Tax Benefits Roll Forward | Unrecognized Tax Benefits The Company records interest and penalties associated with unrecognized tax benefits as a component of income tax expense. During the years ended December 31, 2018 and 2017, the Company recorded a potential interest benefit of $0.3 million and $1.1 million, respectively. The Company recorded $0.3 million of potential interest expense during the year ended December 31, 2016. There was no accrued interest at December 31, 2018. Total accrued interest at December 31, 2017 and 2016 of $0.4 million and $1.4 million, respectively, was included in Other liabilities on the Consolidated Balance Sheets. During the years ended December 31, 2018 and 2017, the Company recorded potential penalty expense of $0.1 million and $0.2 million, respectively. Total accrued penalties at December 31, 2018 and 2017 of $0.3 million and $0.2 million, respectively, were included in Other liabilities on the Consolidated Balance Sheets. There was no recorded potential penalty expense or accrued penalties at December 31, 2016. The Company's tax returns are routinely audited by the tax authorities in the relevant jurisdictions. For tax years before 2017, the Company is no longer subject to U.S. federal income tax examination. For tax years before 2013, the Company’s Malaysian subsidiaries are no longer subject to examination. It is reasonably possible that the gross amount of unrecognized tax benefits will decrease by $0.1 million during the next twelve months. Included in the balance of total unrecognized tax benefits at December 31, 2018 are potential benefits of $3.5 million, which if recognized, would affect the effective rate on earnings from continuing operations. Given the Company's current valuation allowance position, no benefit is expected to result from the reversal of any uncertain tax position associated with the acquired attributes.
