Silgan and its subsidiaries file U.S. Federal income tax returns, as well as income tax returns in various states and foreign jurisdictions. The Internal Revenue Service, or IRS, has completed its review of the 2017 tax year with no material change to our filed federal income tax return. We have been accepted into the Compliance Assurance Program for the 2018 and 2019 tax years which provides for the review by the IRS of tax matters relating to our tax return prior to filing.
