I have raised before the question of whether so-called socially conscious investing would be a breach of fiduciary duty if undertaken by a pension plan or 401(k) fiduciary. The National Law Journal has a neat opinion piece by law professor Edward Zelinsky right now to the effect that it would be. Here’s a link, although you may have to be a subscriber to access it. Either way, I think I am going to exercise my fair use rights under copyright law, and quote the professor’s conclusion on this particular point:

Inconvenient truth no. 3: Social investment dilutes fiduciary standards. Divestment for worthy causes, like other forms of social investing, opens the door to less noble uses of public pension funds by diluting the fiduciary standards governing pension trustees’ investment decisions. Suppose that a group seeks to use public retirement assets to support the Hamas-dominated regime in Gaza. There are, of course, persuasive distinctions between an anti-Sudan investment policy and a pro-Hamas policy. However, politicizing public pension investments for good causes will invariably turn such pensions into battlegrounds as others seek support for their causes, not all of which will be attractive.

Instructive in this context are the traditional standards of fiduciary conduct including, in Benjamin N. Cardozo’s famous formulation, "the duty of undivided loyalty." The insight animating this formulation is convincing: It does not matter if a fiduciary (like a public pension trustee) dilutes his loyalty to beneficiaries’ welfare for a commendable cause. Once fiduciaries weaken that loyalty by considering any objective other than the well-being of their beneficiaries, the door is opened to causes that may not be meritorious. Even if trustees only pursue estimable objectives, they pursue such objectives with others’ money, i.e., retiree’s retirement resources.

I discussed in an earlier post an academic paper by a different professor arguing to the contrary, and you can find that here. So now you have both sides of the coin, and can make your own call. For me, though, I will return to my own roots – and initial instincts – as a litigator, and repeat something I have said before: if representing a client sued for breach of fiduciary duty, I’d rather be in the position of defending an investment strategy that called for maximum possible returns than one calling for only the maximum possible returns available by investing in good doobie companies.
