Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	On January 22, 2013, a "target" award of 5,400 performance restricted stock units (PRSUs) was granted to the reporting person pursuant to Comerica Incorporated's long-term incentive plan. The PRSUs are settled in stock, with accrued dividend equivalents paid out annually in cash, and vest in one installment at the end of a 3-year performance period. If, during any year in such performance period, Comerica falls below the Tier 1 Capital Threshold defined by the Federal Reserve for well capitalized banks, 15% of the target award will be forfeited, with a maximum reduction of 45%. Previously, Comerica's Governance, Compensation and Nominating Committee certified that performance was achieved for the 2013 and 2014 fiscal years. On February 23, 2016 the Committee certified that performance was achieved for the 2015 fiscal year. The number of PRSUs reported in this Form 4 represents the additional portion of the award that is not subject to reduction due to the achievement of the 2015 performance results.
(2)	Includes shares acquired through employee stock plans, shares purchased with reinvested dividends and stock units held pursuant to a deferred compensation plan as of February 23, 2016.
(3)	The options vest in four equal annual installments (based on the original grant amount) beginning on the date indicated in this column.
