Specific deposit agreements and depositary receipts will contain additional important terms and provisions and will be incorporated by reference into the
registration statement that includes this prospectus before we issue any depositary shares. The descriptions herein and in the applicable prospectus supplement do not restate those agreements and receipts in their entirety and do not contain all of
the information that you may find useful or that may be important to you. You should refer to the provisions of the applicable deposit agreement and deposit certificate because they, and not the summaries, define your rights as holders of the

“Where You Can Find More Information” above.

General

We may elect to offer fractional shares of preferred stock rather than full shares of preferred stock. If so, we will issue “depositary receipts”
for these “depositary shares.” Each depositary share will represent a fraction of a share of a particular series of preferred stock. Each holder of a depositary share will be entitled, in proportion to the fraction of preferred stock
represented by that depositary share, to the rights and preferences of the preferred stock, including dividend, voting, redemption, conversion and liquidation rights, if any. We will enter into a deposit agreement with a depositary, which will be
named in the related prospectus supplement.

In order to issue depositary shares, we will issue preferred stock and immediately deposit these shares with
the depositary. The depositary will then issue depositary receipts in accordance with the terms of the deposit agreement to the persons who purchase depositary shares. Each whole depositary share issued by the depositary may represent a fraction of
a share held by the depositary. The depositary will issue depositary receipts in a form that reflects whole depositary shares, and each depositary receipt may evidence any number of whole depositary shares.

We issued 6,000,000 depositary shares in a public offering, which each represent 1/1000th ownership interest in a share of our outstanding Series G
Preferred Stock. Additionally, in connection with the Sterling merger, we issued and registered 5,400,000 depositary shares, each representing 1/40th interest in a share of our outstanding Series G Preferred Stock. The depositary
