We estimate that we will pay approximately $1.8 million for expenses, excluding the underwriting discount, allocable to the offering. We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments that the underwriters may be required to make in respect thereof. We have agreed that we will not, for the 30-day period from the date of this prospectus supplement, without first obtaining the prior written consent of the representatives, directly or indirectly, issue, sell, offer to contract S-45

or grant any option to sell, pledge, transfer or otherwise dispose of, any depositary shares or preferred stock or securities exchangeable for or convertible into depositary shares or preferred
stock, except for the depositary shares and related shares of Series B Preferred Stock sold to the underwriters pursuant to the underwriting agreement.

The depositary shares will be a new issue of securities, and there is currently no established trading market for the depositary shares. We
intend to apply to list the depositary shares on the NYSE under the symbol “CMA PrB.” If the listing is approved, trading of the depositary shares on the NYSE is expected to commence within 30 days after the depositary shares are first
issued. The underwriters have advised us that, subject to obtaining any necessary approval from the NYSE, they presently intend to make a market in the depositary shares prior to the commencement of trading on the NYSE. However, the underwriters are
not obligated to do so and may discontinue making a market in the depositary shares at any time without notice. There is currently no secondary market for the depositary shares and one may not develop, even if the depositary shares are approved for
listing. If the secondary market for the depositary shares is limited, there may be few or no buyers if you choose to sell your shares and this may reduce the price you receive or your ability to sell the shares at all.
