Equity [Abstract] |
Equity Transactions | Equity Transactions The Company did not make any share repurchases during the three months ended March 31, 2017. As of March 31, 2017, there were 200,000 shares available to be repurchased of a total of 3,430,045 shares of Company common stock that had been approved by the Company's Board of Directors. Under the terms of the program, the Company may repurchase shares of its common stock from time to time at its discretion through open market repurchases, privately negotiated transactions and/or other mechanisms, depending on price and prevailing market and business conditions. The program, which has no specified term, may be suspended or terminated at any time. During the three months ended March 31, 2017, the Company issued 1,046,500 shares of common stock and 1,150,000 shares of 7.25% mandatory convertible preferred stock ("MCPS") in public offerings, which included the exercise of the underwriters' over-allotment option, for net proceeds of $220.1 million, after underwriting discounts, commissions and other offering expenses. The MCPS has a liquidation preference of $100.00 per share. Unless converted earlier, each share of MCPS will convert automatically on February 1, 2020 (the "mandatory conversion date") into between 0.7576 and 0.9091 shares of common stock, subject to customary anti-dilution adjustments. The number of shares of common stock issuable upon conversion will be determined based on the average volume-weighted average price per share of the Company's common stock over the 20 consecutive trading day period beginning on, and including, the 22nd scheduled trading day immediately preceding the mandatory conversion date. Each share of MCPS can be converted prior to the mandatory conversion date, at the option of the holder, at the minimum conversion rate of 0.7576 or at specified rate, in the event of a fundamental change as defined in the certificate of designations of the MCPS. Dividends on the MCPS will be payable on a cumulative basis when, as and if declared by the board of directors, at an annual rate of 7.25% on the liquidation preference of $100.00 per share. If declared, these dividends will be paid in cash, or, subject to certain limitations, in shares of common stock (or a combination) on February 1, May 1, August 1, and November 1 of each year, commencing May 1, 2017, and continuing to, and including, February 1, 2020. On February 15, 2017, the Company declared a quarterly cash dividend of $0.45 per common share to be paid on May 10, 2017 to shareholders of record at the close of business on April 28, 2017. The Company also declared a quarterly cash dividend of $1.8125 per share on the Company's 7.25% MCPS to be paid on May 1, 2017 to shareholders of record at the close of business on April 15, 2017.
