Critics of the shareholder proposal argue that it's incompatible with ERISA law. "A company can decide to pursue climate-based objectives, but ERISA does not permit the company to pursue those objectives in its 401(k) plan if doing so would conflict with the financial interests of the participants," said Kent A. Mason, a partner at Davis & Harman LLP in Washington.
"You have to be able to conclude that the fund that takes ESG into account is at least as financially prudent as a fund that doesn't," Mr. Mason added. "If you can't conclude that, you can't offer it."
Greg Mykytyn, senior vice president with Commerce Street Peak Advisors in Dallas, also bemoans the proposal, saying it makes shareholders "investment fiduciaries" who can't be held accountable to participants and beneficiaries.
"You're essentially making the shareholders part of the investment committee of the ERISA-backed plan, and that is just ludicrous," Mr. Mykytyn said.
If retirees file a lawsuit against the investment committee that an ESG fund "wasn't all that it was said to be," it's the fiduciaries who are on the hook, not the shareholders who bear no liability, he said.
Mr. Mykytyn also fears that the proposal will be a "brain drain" on 401(k) plan committees as "competent committee members will not want to be a fiduciary when they lack full discretion."
Joe DeBello, a managing consultant in the retirement and wealth division of OneDigital Investment Advisors in Orlando, Fla., takes issue with the idea of swapping out low-cost index funds with higher-fee ESG fund options, a move that he says will raise costs for plan participants by 70 to 80 basis points. "It seems to fly in the face of everything that's been decided by the courts in terms of prudent processes and governance," he said. "It flies in the face of all the relentless pressure on plan fees."
As You Sow's Mr. Behar counters that fees alone aren't everything. Plan sponsors also need to consider fund performance.
"The whole idea that you only judge a fund by its fees is very flawed," he said. "In terms of judging returns or pecuniary results, you need to judge fees and returns together."
Davis & Harman's Mr. Mason brushes aside the argument. Whether ESG funds are better or worse than non-ESG funds for participants is up to the plan fiduciary — not shareholders — to determine, he said. "It's ultimately up to the fiduciary in a very financially oriented way of thinking to make that determination," he said.
