Dear Ms. Cvrkel:

This letter is being submitted on behalf of Gentex Corporation, a Michigan corporation (the "Company") in response to the comment letter from the staff of the Securities and Exchange Commission dated November 19, 2013 (the "Comment Letter"). In accordance with the instructions contained in the Comment Letter, this response letter provides the requested information.

The following response is provided in italics under the comment contained in the Comment Letter.

Form 10-Q for the Quarter Ended September 30, 2013

Note 4. Goodwill and Other Intangible Assets

1.
We note from your disclosure in Note 4 that the portion of the purchase price allocated to the Exclusive Licensing Agreement was assigned an indefinite useful life. Please explain to us why you believe an indefinite life is appropriate for this asset. As part of your response, please provide us with the pertinent terms and conditions of the licensing agreement, including the length of time covered by the agreement.

Response: In assigning a useful life to the executed Exclusive License Agreement and related amendments (the "Agreement"), with a U.S. based garage door manufacturer ("Partner"), the Company considered the provisions of ASC 350 Intangibles, Goodwill and Other. Giving consideration to this guidance and the language, substance, and longevity of the Agreement, an indefinite remaining useful life was determined to be appropriate for the Agreement for several reasons set forth below.

The terms of the Agreement provide for a perpetual exclusive agreement, subject only to termination with a 36 month advance written notice. Despite the termination provision included within the Agreement, the Company has considered the fact that the Agreement has been in place since 1995. In addition, while the Agreement historically included finite terms subject to renewal, an amendment providing for a perpetual exclusive agreement was executed in 2012 and, as such, the Agreement now provides for an indefinite period. The Company believes the duration of time which the Agreement has been in place, as well as the 2012 renewal and amendment, support an indefinite life being assigned to the underlying asset, as there are no other legal or contractual provisions that would limit the useful life of the Agreement.
The Company has every intention to maintain the Agreement in perpetuity. The Agreement grants the Company exclusive access to current and future versions of the Partner’s proprietary garage door opening technology that is integrated into HomeLink products. Prior to the acquisition of HomeLink, the Company integrated the HomeLink product as a value-added feature into its automatic-dimming rearview mirrors. As a result of the acquisition, the Company will also manufacture HomeLink products that will be integrated into other areas of the automobile (outside of the mirror).

The Company also believes that the Partner has every intention to maintain the Agreement into perpetuity, as that is consistent with the Partner's historic pattern of behavior and the market royalty rate for exclusivity is estimated to be significantly higher than a non-exclusive market rate.

Further, the Company has considered the nature of the technology, the long term sales projections, known technological advances in the product and industry, competition (both historical competition as well as future competition from within the automotive industry, and for similar technology outside of the automotive industry), as well as current product life cycles and the product roadmap in assigning an indefinite useful life. None of these factors suggested a limitation on the useful life for the foreseeable future. In assigning an indefinite useful life, the Company recognizes that this does not indicate that the life of the asset is forever, however it is beyond the foreseeable future.

Finally, the valuation technique used to establish the fair value measurement of the Agreement prepared in connection with purchase accounting employed a perpetual life as the Company believes that the longevity of the Agreement evidences that there is no foreseeable limit on the period of time which the asset will contribute to the cash flows of the Company.
