Item 5.07, Submission of Matters to a Vote of Security Holders in the Original Form 8-K. Except as set forth herein, no other modifications have been made to the Original Form 8-K.

As previously disclosed in the Original Form 8-K, at the Annual Meeting, in a non-binding advisory vote on the frequency of the advisory vote on the compensation paid to the Company's named executive officers ("say-on-pay") the Company’s shareholders voted in favor of holding say-on-pay votes annually. In accordance with this result and its previous recommendation (as set forth in the definitive proxy statement for the Annual Meeting filed with the SEC on March 15, 2017), the Board of Directors determined that the Company will hold advisory say-on-pay votes on named executive officer compensation on an annual basis until the next required vote on the frequency of such say-on-pay votes or until the Board determines that it is in the best interest of the Company to hold such vote with a different frequency.
