Insights

Securities Analyst

TL;DR: Small reported sale sourced to tax withholding on RSU vesting; not clearly material to Comerica's capitalization.

The transaction code F indicates the disposition resulted from tax withholding relating to restricted stock unit vesting rather than an open-market sale by the reporting person. The quantity—683 shares at $70.58—reduces Ms. Fleming's direct holdings to 8,741 shares. Given the share count and the lack of other transactions reported on this Form 4, the trade appears administrative and routine. No derivative activity or additional disposals were reported. For investors, this is a standard insider reporting of compensation-related share withholding rather than a signal of strategic disposition.

Corporate Governance Expert

TL;DR: Filing documents required disclosure of compensation-related withholding; filing appears complete and signed via power of attorney.

The Form 4 discloses the nature of the transaction (tax withholding on RSUs) and provides the post-transaction beneficial ownership figure. The signature block shows the filing was executed by a named attorney-in-fact, which is standard practice. There is no indication of a Rule 10b5-1 plan election box being checked. From a governance perspective, the disclosure meets Section 16 reporting norms and does not by itself raise compliance concerns.
