b) | Preferred Shares
Series A Preferred Shares During March 2012 and concurrent with the issuance of our 6.875% Series C preferred shares, we issued an irrevocable notice of redemption for 6,000,000 of our 7.25% Series A preferred shares, representing an aggregate liquidation preference of $150 million. In connection with this notice, we recognized a $5 million loss on redemption (calculated as the difference between the redemption price and the carrying value, the latter of which is net of original issue costs) as a reduction in determining our net income available to common shareholders. During May 2013 and concurrent with the issuance of our Series D preferred shares (see below), we issued an irrevocable notice of redemption for the 4,000,000 Series A preferred shares outstanding, representing an aggregate liquidation preference of $100 million. In connection with this notice, we recognized a $3 million loss on redemption. Series B Preferred Shares During April 2012, we closed a cash tender offer for any and all of our outstanding 7.50% Series B preferred shares at a purchase price of $102.81 per share. As a result, we purchased 2,471,570 Series B preferred shares for $254 million. In connection with this tender offer, we recognized a $9 million loss on repurchase. Series D Preferred Shares During May 2013, we issued $225 million of 5.50% Series D preferred shares, par value $0.0125 per share, with a liquidation preference of $25.00 per share. We may redeem the Series D preferred shares on or after June 1, 2018 at a redemption price of $25.00 per share. Dividends on the Series D preferred shares are non-cumulative. Consequently, if the Board of Directors does not authorize and declare a dividend for any period, holders of the Series D preferred shares will not be entitled to receive a dividend for such period, and such undeclared dividend will not accumulate and be payable. Holders of the Series D preferred shares will be entitled to receive, only when, as and if declared by the Board of Directors, non-cumulative cash dividends from the original issue date, quarterly in arrears on the first day of March, June, September and December of each year, commencing on September 1, 2013, without accumulation of any undeclared dividends. To the extent declared, these dividends will accumulate, with respect to each dividend period, in an amount per share equal to 5.50% of the liquidation preference per annum. The holders of the Series D preferred shares, as well as our previously issued preferred shares, have no voting rights other than the right to elect a specified number of directors if preferred share dividends are not declared and paid for a specified period.
