• SEC Filings

As previously reported in the Original 8-K, in an advisory (non-binding) vote concerning the frequency of future advisory votes on executive compensation held at the Company’s Annual Meeting, the Company’s shareholders cast the highest number of votes for an annual frequency, consistent with the recommendation of the Company’s Board of Directors. Accordingly, in light of the voting results and other factors, the Board of Directors has determined that the Company will hold an annual advisory vote on executive compensation until the next advisory vote concerning the frequency of future advisory votes on executive compensation is held.
