Amendment Description Management of the Company, in consultation with the Audit Committee of Astronics Corporation's (the "Company's") Board of Directors, has identified a material weakness in our internal control over financial reporting concerning the design of information technology change controls over a report writing application. Additionally, management identified deficiencies in certain review controls over the financial statement consolidation process, which when aggregated along with the information technology change controls matter described above, aggregate to a material weakness over the financial statement close process as of December 31, 2016.  Management does not expect adjustments to any previously issued financial statements as a result of these deficiencies. As a result of the material weakness described above, management has concluded that the Company’s internal control over financial reporting was not effective at December 31, 2016 and, accordingly, its disclosure controls and procedures were not effective at December 31, 2016 or April 1, 2017. We are amending our Annual Report on Form 10-K for the fiscal year ended December 31, 2016 and our Quarterly Report on Form 10-Q for the period ended April 1, 2017 to reflect the conclusion by management that there was a material weakness in internal control over financial reporting as of the end of the periods covered by these reports. Ernst & Young LLP’s auditor’s report on the Company’s internal control over financial reporting will also be revised to state that the Company’s internal control over financial reporting at December 31, 2016 was not effective.
