On November 21, 2014, our board of directors increased its size to eight directors and elected Cindy L. Davis to serve as a director and fill the newly created vacancy. Ms. Davis will serve until the next annual meeting of shareholders and until her successor is duly elected and qualified. The board has determined not to name her to any committees at this time. Ms. Davis initially will participate in the company’s standard compensation program for non-employee directors, as disclosed in the proxy statement relating to our 2014 annual meeting of shareholders.

There are no current or proposed transactions in which Ms. Davis, or any member of her immediate family, has an interest that is required to be disclosed under Item 404(a) of Regulation S-K promulgated by the Securities and Exchange Commission.

On November 26, 2014, we issued a press release announcing Ms. Davis’s election to our board of directors. A copy of the press release is furnished as Exhibit 99.1 hereto.
