01 · The brief
Plain-English summaryWhat this bill actually does

The bill amends the Investment Advisers Act to require investment advisers to solicit and pass through proxy voting instructions from underlying investors in passively managed funds when the adviser (and affiliates) control more than 1% of a registrant’s voting securities. It sets exceptions for routine matters and certain majority-approval votes, requires provision of proxy materials and at least five business days to return instructions, prohibits partial-solicitation and reimbursement from registrants, and creates a safe harbor and a two-year delayed effective date.

Why people may split

Liberals emphasize restoring investor democracy and constraining manager power.

Watch point

Relative to its intended legislative type, this bill is a clearly targeted substantive policy change with well-specified operational mechanics integrated into existing securities law, but it contains limited fiscal acknowledgment and sparse accountability/reporting provisions.

It also inserts a reference to voting instructions into the Securities Exchange Act.
