Why Collective Investment Trusts Keep Taking Over the Menu

Pull up a target-date lineup that got rebuilt in the last few years and count the tickers. You may not find any. The slot that used to hold a brand-name target-date mutual fund now holds a collective investment trust, often from the same asset manager, running the same glidepath, at a lower price. The committee approved what looked like a share-class swap, and it was a change of vehicle.

This is one of the bigger structural shifts in defined contribution menus, and it has been building for years. CITs have already passed mutual funds as the most common target-date vehicle, and they keep moving down-market into mid and small plans as recordkeepers add them. Cost drives most of it. The tradeoffs are real too, and many get waved away in the rush to lower the expense ratio.

What a CIT is

A collective investment trust is a pooled vehicle maintained by a bank or trust company and sold only to qualified retirement plans and other institutional investors. It is closed to the public, and that fact explains most of the price difference.

Because a CIT is not a retail product, it is exempt from registration under the Securities Act of 1933, the Securities Exchange Act of 1934, and the Investment Company Act of 1940. It has no prospectus, no independent fund board of the kind a 40 Act fund requires, and none of the ongoing SEC compliance machinery a registered mutual fund pays for out of its expense ratio. Strip those costs out and a CIT holding the same securities, run by the same portfolio team, usually lands cheaper than the mutual fund version.

A CIT is still an ERISA fiduciary vehicle, and the trustee is a fiduciary. Because pricing is negotiated by plan size rather than published in a prospectus, a CIT can offer fee tiers a mutual fund share class often cannot. For a growing plan, that gives you a bargaining point at the next pricing review.

The tradeoffs that rarely make the one-pager

Lower cost comes with consequences. A few things change when you move from a mutual fund to a CIT, and a committee should hear all of them before it votes.

• Public transparency drops. There is no prospectus and no public ticker most participants can look up on a retail site. Disclosure runs through the trust's fact sheets, its disclosure document, and the recordkeeper instead of the SEC's public filing system. The information exists in places your participants are not used to looking.
• Daily pricing works differently. A mutual fund strikes a public NAV each day that anyone can pull from a financial website. A CIT is valued for the plan through the trustee and recordkeeper and is not broadcast the same way. For a participant who likes to check a quote, that is worth explaining.
• Comparison gets harder. CITs lack the long, standardized, publicly tracked performance history a decades-old mutual fund carries, and ratings coverage is thinner. Benchmarking one, especially a newer one, takes more work than typing a ticker into a database.
• Documentation moves to you. With a mutual fund, the prospectus does a lot of the disclosure work. With a CIT, gathering the disclosure document, the fee schedule, and the trustee's materials falls to the plan's process.

In many plans a CIT is the better choice. A public, retail-facing wrapper has real value, though, and you are trading some of it away for basis points. Say that in the meeting so the committee makes a deliberate decision.

The 403(b) exception

Advisors get sloppy here. CITs are harder for 403(b) plans to use than for 401(k) plans. The securities and tax law that governs what a 403(b) can hold has long pointed those plans toward annuity contracts and mutual funds, which left CITs outside the eligible-investment box.

There has been steady pressure to open 403(b) menus to CITs, and pieces of it have moved. The access is still less clear-cut than on the 401(k) side, and the answer can turn on plan type and the specific statutory provisions in play. If you advise nonprofits, hospitals, or schools, do not assume the CIT you just put in a 401(k) is available next door in the 403(b). Confirm eligibility for that specific plan before you build the lineup. Telling a 403(b) sponsor they can hold a CIT when they cannot is the kind of error that follows you.

Document the swap

The cost case for CITs is strong enough that the move is often easy to justify. You still have to document it. You are the named fiduciary, and a lower expense ratio alone does not amount to a process.

Make sure the file shows the work: an IPS that permits collective trusts as eligible investments, a side-by-side comparing the CIT and the mutual fund on net cost, strategy, and the transparency differences above, the disclosure document and fee schedule in hand, and committee minutes recording that you weighed the tradeoffs and made a choice. That paper is tedious to assemble from a stack of fact sheets, which is where keeping one source of truth per plan, with source documents attached, pays off. The file should show that you ran a real process and reached your own judgment.

The menu will keep tilting toward collective trusts because the cost math favors participants. Make sure each swap reflects a decision you can explain three years from now.
