Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures.

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)) of the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered in this Form 10-K, our disclosure controls and procedures were effective to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the required time periods and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting.

During 2016, we continued to enhance our controls over revenue to estimate the effects of returns and allowances provided to distributors in anticipation of recording revenue at the time of sale to the distributor originating through the ON Semiconductor processes and aligning our revenue recognition processes between the acquired Fairchild operations and ON Semiconductor in the first half of 2017.

There have been no other changes to our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that occurred during the quarter ended December 31, 2016 which have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We continue to integrate Fairchild’s operations into our systems and internal control environment, and expect to complete the integration by the fourth quarter of 2017.

Management’s Report on Internal Control Over Financial Reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)). Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2016. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in Internal Control - Integrated Framework 2013. Based on this assessment, management has concluded that our internal control over financial reporting was effective as of December 31, 2016.

Management’s assessment of the effectiveness of our internal control over financial reporting as of December 31, 2016 excluded Fairchild, which was acquired by the Company on September 19, 2016. Excluded assets of Fairchild as of December 31, 2016 represent approximately 25% of consolidated assets, and Fairchild’s revenues for the period from September 19, 2016 through December 31, 2016 represents approximately 11% of consolidated revenues.
