All of the $16.4 million of unrecognized tax benefits, interest and penalties would impact our effective tax rate if recognized. As previously disclosed, a non-U.S. subsidiary, Innospec Performance Chemicals Italia Srl, is subject to an ongoing tax audit in relation to the period 2011 to 2014 inclusive. The Company has determined that additional tax, interest and penalties totaling $3.1 million may arise as a consequence of the tax audit. This includes a reduction in interest accrued of $0.2 million recorded in the three months to March 31, 2020. As any additional tax arising as a consequence of the tax audit would be reimbursed by the previous owner under the terms of the sale and purchase agreement, an indemnification asset of the same amount is recorded in the financial statements to reflect this arrangement. As previously disclosed, in 2018 the Company recorded an unrecognized tax benefit of $10.8 million which primarily relates to a potential adjustment that could arise as a consequence of the Tax Cuts and Jobs Act, but for which retrospective adjustment to the filed 2017 U.S. federal income tax returns was not permissible. The Company accrued a net increase in interest of $0.2 million in the three months to March 31, 2020 relating to this matter. The Company and its U.S. subsidiaries remain open to examination by the IRS for years 2016 onwards under the statute of limitations. The Company’s subsidiaries in foreign tax jurisdictions are open to examination including Germany (2015 onwards), Switzerland (2015 onwards), Spain (2016 onwards), France (2017 onwards) and the United Kingdom (2018 onwards).
