 in whole but not part, at a redemption price equal to $10,000 per share (equivalent to $25 per depositary share), plusany declared and unpaid dividends on the shares of Preferred Stock called for redemption up to the redemption date, without accumulation of undeclared dividends. A “regulatory capital treatment event” means the good faith determination by M&T that, as a result of (i) any amendment to, or change in, the laws, rules or regulations of the United States or any political subdivision of or in the United States that is enacted or becomes effective after the initial issuance of any share of the Preferred Stock, (ii) any proposed change (including any such change with a prospective effect) in those laws, rules or regulations that is announced after the initial issuance of any share of the Preferred Stock (including any announced change with a prospective effect), or (iii) any official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws, rules or regulations that is announced after the initial issuance of any share of the Preferred Stock, there is more than an insubstantial risk that M&T will not be entitled to treat the full liquidation value of the shares of the Preferred Stock then outstanding as “additional tier 1 capital” (or its equivalent or successor) for purposes of the capital adequacy rules of the Federal Reserve (or, as and if applicable, the capital adequacy rules or regulations of any successor appropriate federal banking agency), as then in effect and applicable, for as long as any share of the Preferred Stock is outstanding. Dividends will cease to accrue on those shares on the redemption date. Redemption of the Preferred Stock is subject to our receipt of any required prior approvals from the Federal Reserve or from any successor appropriate federal banking agency and to the satisfaction of any conditions set forth in the capital adequacy rules of the Federal Reserve applicable to the redemption of the Preferred Stock. Procedures If we redeem shares of the Preferred Stock, we will provide notice by first class mail (or, if the Preferred Stock or depositary shares are issued in book-entry form through DTC or another facility, in accordance with the procedures of such facility) to the holders of record of the shares of Preferred Stock to be redeemed. Such notice will be provided not less than 30 days and not more than 90 days prior to the date fixed for the redemption. Each notice of redemption will include a statement setting forth:
