Equity [Abstract] |
Mandatorily Redeemable Preferred Stock | Mandatorily Redeemable Term Preferred Stock In February 2012, we completed a public offering of 1,540,000 shares of 7.125% Series C Cumulative Term Preferred Stock, par value $0.001 per share, or the Term Preferred Stock, at a public offering price of $25.00 per share. Gross proceeds of the offering totaled $38.5 million and net proceeds, after deducting offering expenses borne by us, were $36.7 million. The shares of the Term Preferred Stock had a mandatory redemption date of January 31, 2017. During the nine months ended September 30, 2016, we redeemed all outstanding shares of the Term Preferred Stock. Accordingly, we wrote-off unamortized offering costs of $0.06 million and $0.2 million during the three and nine months ended September 30, 2016, respectively, which were recorded to interest expense in our condensed consolidated statements of operations. The Term Preferred Stock was recorded as a liability in accordance with ASC 480, “Distinguishing Liabilities from Equity,” which states that mandatorily redeemable financial instruments should be classified as liabilities and therefore the related dividend payments are treated as a component of interest expense in the condensed consolidated statements of operations.
