The investor presentation included as Exhibit 99.1 to this report may be presented at meetings with investors, analysts, and others, in whole or in part and possibly with modifications, during the fiscal year ending December 31, 2017.

The investor presentation includes financial information not prepared in accordance with generally accepted accounting principles (“GAAP”). A reconciliation of the non-GAAP financial measures to the most directly comparable financial measures prepared in accordance with generally accepted accounting principles, as required by Regulation G, is available within Exhibit 99.1 and on our website at www.ctscorp.com. The Company believes that the non-GAAP financial measures provide investors additional ways to view our operations which we believe provide a more complete understanding of our business than could be obtained absent these disclosures. We believe the non-GAAP financial measures also provide investors a useful tool to assess shareholder value.
