GT&#8217;s&#160;report&#160;on the Company&#8217;s&#160;internal control over financial reporting as of December&#160;31, 2019 did not contain any adverse opinion or disclaimer of opinion, nor was it qualified as to uncertainty, audit scope, or accounting principles, however it was modified to exclude the internal control over financial reporting of Stihler Electronic GmbH.

In view of this material weakness, GT&#8217;s report on the effectiveness of the Company&#8217;s internal control over financial reporting as of December&#160;31, 2018 indicated that the Company did not maintain effective internal control over financial reporting as of December&#160;31, 2018. The Company implemented a remediation plan that included development of enhanced risk assessment procedures and controls over the monitoring of elevated access and segregations of duty conflicts. The Company completed testing of the operating effectiveness of the enhanced controls and found them to be effective as of September&#160;30, 2019 and, therefore, concluded that the material weakness was remediated as of September&#160;30, 2019. The subject matter of this material weakness was discussed by the Audit Committee with GT.
