To amend the Securities Exchange Act of 1934 to provide for duties of certain investment advisors, asset managers, and pension funds with respect to voting on shareholder proposals, and for other purposes.

HR 4648 requires large investment firms, including asset managers and pension funds, to report annually to the Securities and Exchange Commission (SEC) on their voting for shareholder proposals. These firms must explain each vote, detail how often they followed proxy advisory firm recommendations, and show how they balanced those recommendations with their duty to act in shareholders' best economic interest. Firms managing over $100 billion in assets must also conduct an economic analysis before voting on most proposals (excluding votes aligned with board recommendations) to confirm alignment with shareholder financial interests and include this analysis in their report. The bill aims to increase transparency in how investment firms exercise voting power on corporate matters.
