[1] | Additionally, during January 2018, the underwriting financial institutions for the Class M issuance elected to exercise the over-allotment option and as a result, the Company issued an additional 1,380,000 Class M Depositary Shares, each representing a one-thousandth fractional interest in a share of the Company's 5.250% Class M Cumulative Redeemable Preferred Stock, $1.00 par value per share. The Company received net proceeds before expenses of $33.4 million from this offering.
[2] | Redemption charges resulting from the difference between the redemption amount and the carrying amount of the respective preferred stock class on the Company' Consolidated Balance Sheets are accounted for in accordance with the FASB's guidance on Distinguishing Liabilities from Equity. These charges were subtracted from net income attributable to the Company to arrive at net income available to the Company's common shareholders and used in the calculation of earnings per share.
[3] | The Company partially redeemed 9,000,000 depositary shares of its issued and outstanding Class I Preferred Stock, representing 56.25% of the issued and outstanding Class I Preferred Stock.
