Preferred and Common Stock
PREFERRED AND COMMON STOCK
Preferred Stock
We are authorized to issue 500,000 shares of preferred stock. None of these preferred shares are issued.
Common Stock
On September 2, 2015, our Board of Directors authorized a program to repurchase up to $200.0 million shares of our common stock. Purchases may take place on the open market or otherwise, and all or part of the repurchases may be made pursuant to Rule 10b5-1 plans or in privately negotiated transactions. The timing of repurchases is at our discretion and will depend upon several factors, including market and business conditions, future cash flows, share price, and share availability. Repurchased shares are retired and returned to an authorized but unissued status. The repurchase program may be suspended or discontinued at any time without prior notice. At October 31, 2017, authorization for $134.1 million of repurchases remained under our share repurchase program. We do not anticipate additional repurchases in the near future.
