If we are not paying full dividends on any outstanding parity stock, we will not be able to pay full dividends on the Series B Preferred Stock.

When dividends are not paid in full on the shares of Series B Preferred Stock or any shares of parity stock, including our
outstanding Series A Preferred Stock, for a dividend period, all dividends declared with respect to shares of Series B Preferred Stock and all parity stock for such dividend period shall be declared pro rata so that the respective amounts of
such dividends declared bear the same ratio to each other as all accrued but unpaid dividends per share on the shares of Series B Preferred Stock for such dividend period and all parity stock for such dividend period bear to each other. Therefore,
if we are not paying full dividends on any outstanding parity stock, we will not be able to pay full dividends on the Series B Preferred Stock and, in turn, the Depositary Shares.

Holders of the Depositary Shares may not be entitled to the dividends-received deduction.

Distributions paid to corporate U.S. holders of the depositary shares may be eligible for the dividends-received deduction if we have current
or accumulated earnings and profits, as determined for U.S. federal income tax purposes. See “Material U.S. Federal Income Tax Considerations.” Although we presently have accumulated earnings and profits, we may not have sufficient

Income Tax Considerations” for additional information regarding certain U.S. federal income tax considerations related to the ownership and disposition of our Series B Preferred Stock (and related depositary shares). If any distributions on
the Series B Preferred Stock (and the related depositary shares) with respect to any fiscal year are not eligible for the dividends-received deduction because of insufficient current or accumulated earnings and profits, the market value of the
Depositary Shares may decline.
