This Registration Statement is solely for the registration of additional shares of common stock of Comerica Incorporated for issuance under the Comerica Incorporated Preferred Savings Plan (the “Plan”).  Therefore, pursuant to General Instruction E to Form S-8, the contents of the earlier registration statements relating to the Plan and/or shares carried over into the Plan (Registration Statement No. 333-50966 filed on November 30, 2000 and Registration Statement No. 333-24567 filed on April 4, 1997) are incorporated by reference into this Registration Statement.

ITEM 3.                                                INCORPORATION OF DOCUMENTS BY REFERENCE.
The following documents filed with the Commission by Comerica Incorporated (“Comerica” or the “Registrant”) are incorporated in this Registration Statement on Form S-8 (the “Registration Statement”) by reference:
1.    Comerica’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017;

2.    The Plan's Annual Report on Form 11-K for the year ended December 31, 2017;
3.    Comerica's Quarterly Reports on Form 10-Q for the quarters ended March 31, 2018, June 30, 2018 and September 30, 2018;

4.    Comerica's Current Reports on Form 8-K filed with the Commission on January 24, 2018, February 8, 2018, April 26, 2018, July 24, 2018, July 31, 2018 and October 18, 2018; and
5.    The description of Comerica’s common stock, par value $5.00 per share, set forth in Comerica’s Registration Statement on Form S-4/A filed April 5, 2011 (Commission File Number 333-172211) and any amendments, reports or other filings filed with the Securities and Exchange Commission for the purpose of updating that description.
All documents subsequently filed by Comerica pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a post-effective amendment which indicates that all securities offered hereunder have been sold or which deregisters all of the securities offered then remaining unsold, shall be deemed to be incorporated herein by reference and to be a part hereof from the date of filing of such documents.
The validity of the securities has been passed upon by Jennifer S. Perry, Senior Vice President, Assistant Corporate Secretary and Assistant General Counsel, Corporate Finance and Securities, of Comerica. As of November 7, 2018, Ms. Perry beneficially owns or has the rights to acquire an aggregate of less than 1% of Comerica’s common stock.

As permitted by Section 102(b)(7) of the Delaware General Corporation Law (the “DGCL”), Comerica’s certificate of incorporation provides that a director of Comerica shall not be personally liable to Comerica or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liability (a) for any breach of the director’s duty of loyalty to us or our stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) pursuant to Section 174 of the DGCL, or (d) for any transaction from which a director derived an improper personal benefit.
In general, Comerica’s bylaws provide that Comerica shall indemnify its directors and officers to the fullest extent permitted by law. As permitted by Section 145(a) of DGCL, Comerica’s bylaws provide that Comerica shall indemnify each of its directors and officers against expenses (including attorney’s fees) incurred in connection with any proceeding (other than an action by or in the right of Comerica) involving such person by reason of having been an officer or director, to the extent such person acted in good faith and in a manner reasonably believed to be in, or not opposed to, the best interest of Comerica and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. As permitted by Section 145(b) of DGCL, Comerica’s bylaws provide that Comerica shall indemnify each of its officers and directors against expenses (including attorney’s fees) incurred in connection with any action brought by or in the right of Comerica, to the extent

such person acted in good faith and in a manner reasonably believed to be in, or not opposed to, the best interest of Comerica, except that if the director or officer is adjudged to be liable to Comerica, no indemnification shall be made unless and to the extent that the Court of Chancery or any other court shall deem proper, notwithstanding the adjudication of liability.
Unless prohibited by applicable law or regulation, or otherwise required by Section 18(k) of the Federal Deposit Insurance Act, as amended, the determination of whether indemnification of an officer or director is proper under the circumstances (unless ordered by a court) generally shall be made by independent legal counsel chosen by a majority of Comerica’s disinterested directors (even if such disinterested directors constitute less than a quorum) in a written opinion to the board of directors. However, as required by Section 145(c) of DGCL, Comerica must indemnify a director or officer who was successful in defense of any suit. As permitted by Section 145(e) of DGCL, Comerica’s bylaws provide that Comerica may pay expenses incurred by a director or officer in advance, upon receipt of an undertaking that the advance will be repaid if it is ultimately determined that the director or officer is not entitled to indemnity.
As permitted by Section 145(g) of DGCL, Comerica’s bylaws provide that Comerica may purchase insurance on behalf of its directors and officers against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not Comerica would have the power to indemnify such person against such liability under its bylaws. Comerica maintains such insurance.
Comerica has also entered into indemnification agreements with certain of its directors and officers. In addition to the indemnification provisions described above, the indemnification agreements make mandatory the advancement of expenses upon receipt of an undertaking that the advance will be repaid if it is ultimately determined that the party is not entitled to indemnity. The indemnification agreements also provide that, to the extent there must be a determination made as to whether a party is entitled to indemnification, such determination will be made by independent legal counsel selected by a majority of disinterested directors, or, for two years following a change of control, by the party claiming indemnification. Further, the indemnification agreements extend the benefits described above to the party’s spouse.
The foregoing is only a general summary of Comerica’s indemnification agreements and certain aspects of Delaware law and Comerica’s certificate of incorporation and bylaws dealing with indemnification of directors and officers, and does not purport to be complete. It is qualified in its entirety by reference to the detailed provisions of Comerica’s indemnification agreements, Section 145 of the DGCL and the certificate of incorporation and the bylaws of Comerica.
