PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

CTS Corporation (the “Company”) has experienced unexpected delays in the filing of its Annual Report on Form 10-K for the year ended December 31, 2006 within the prescribed time period due to delays experienced in completing the Company’s financial statements as of and for the year ended December 31, 2006. As previously reported, the Company has commenced a review of account reconciliation issues related primarily to accounts payable at its Moorpark, California manufacturing location. The review was initiated by management and is being conducted under the oversight of the Audit Committee of the Board of Directors of the Company. The Company has retained an independent forensic accountant and outside legal counsel to assist in the review. After consultation with the Audit Committee and the Board of Directors, management determined that the Company’s financial statements for the first three quarters of 2006 should not be relied upon.

The Company is currently in the process of completing its review, which it expects to complete prior to April 2007. After the review is completed, the Company’s independent registered public accounting firm must complete the audit of the Company’s financial statements for the year ended December 31, 2006. Additionally, the Company will have to amend and restate the Company’s financial statements for the first three quarters of 2006, and, accordingly, the Company will be unable to file its financial statements as of and for the year ended December 31, 2006.
