Introduction
CITs are playing an increasingly important role in today’s defined contribution plan marketplace. At the end of 2025, CITs represented approximately $3.8 trillion in 401(k) plan assets, almost 40% of total 401(k) assets, up from 30% at the end of 20191. In target-date funds, CITs surpassed mutual funds as the dominant investment vehicle in 2024, and that trend continued in 2025. CITs now represent 54% of total target date fund assets, up from 52% in 2024.2
Much of the early adoption of CITs occurred in the large plan market. However, asset managers have been lowering the minimum required investment levels for CITs, and sponsors of smaller plans are now adopting them. Beyond the interest in the 401(k) market, there is positive legislative and regulatory momentum towards granting CITs access to the 403(b) market, where they have not historically been available. The driving force in plan adoption has been the fact that CITs generally strive to offer the same (or substantially similar) investment strategies as their mutual fund counterparts at a lower net expense. However, their unique structure also provides more flexibility for asset managers and consultants to provide new investment solutions.
While the evolution of CITs is generally a positive development, it has introduced new complexities that plan fiduciaries must consider. Given this, it is important that plan sponsors work with their consultants to educate themselves on CITs, review key considerations, and document the process used to evaluate whether CITs are appropriate for a plan.
CIT basics
A CIT is a pooled investment vehicle maintained by a bank or trust company and available to eligible retirement plans and trusts. Unlike mutual funds, CITs are not registered under the Investment Company Act of 1940. This structure allows for lower fees and product flexibility but also creates certain differences in plan documentation, disclosure, reporting, and platform accessibility.
Many of the asset managers who have historically focused their distribution resources on the defined contribution marketplace have created CITs in an effort to deliver a cost-effective and flexible offering. CIT investment strategies are generally substantially similar versions of popular mutual fund strategies, and they are usually available to any eligible plan, subject to asset minimums.
Lower relative fees are the biggest selling point for CITs, which is made possible because they are institutional trust vehicles available only to eligible retirement plans. Unlike mutual funds, CITs are generally exempt from SEC registration and many mutual fund reporting requirements, which can reduce costs related to prospectus filings, shareholder reporting, retail distribution, advertising, and marketing. That said, similar to mutual funds, CITs fees can vary depending on the share class and availability can be limited based on asset minimums or negotiated arrangements.
Beyond fees, there are several important issues that plan sponsors should evaluate before proceeding. Below is a summary of the primary considerations.
Conclusion
Using CITs can be part of a thoughtful strategy for plan sponsors, as long as they understand their current fees compared to the CIT fees, and the trade-offs related to the considerations listed above. As always, documentation is key. When thinking about using CITs, it is a best practice to amend your investment decision process to include an investment vehicle selection component that addresses these considerations. Fee savings alone does not fully validate the decision to use CITs in the plan’s investment menu.
Recommended actions for plan sponsors include:
CITs are neither inherently better nor worse than other investment vehicles. When sponsors understand the role of CITs in the marketplace and the key considerations associated with this investment vehicle, they are better positioned to make decisions that align with their plan’s objectives and fiduciary responsibilities.

Collective Investment Trusts (“CITs”) are pooled investment vehicles sponsored and maintained by a bank or trust company. Unlike mutual funds, CITs are not subject to oversight by the SEC. CITs and their trustees are subject to the oversight of state banking regulators or the Office of the Comptroller of the Currency. You should consider the CIT’s investment objectives, risks, charges, and expenses carefully before you invest. You should also carefully review the relevant CIT governance documents and/or participation agreements or other offering materials (“CIT Offering Materials”) for the trust before investing. If there is any discrepancy between the CIT Offering Materials and the information in this document, you should rely upon the CIT Offering Materials. There is no guarantee that the CIT will be able to successfully implement its investment strategy or realize its investment objective.
