Unit Investment Trust

The Defining Structural Characteristics

The unit investment trust has four defining structural characteristics that together distinguish it from every other investment vehicle in the registered investment company framework and that are the primary focus of Series 65 examination questions about UITs.

The fixed unmanaged portfolio is the most important characteristic — the securities held by a UIT are selected by the sponsor at the time the trust is assembled and are then held substantially unchanged for the life of the trust. There is no portfolio manager making ongoing buy and sell decisions, no rebalancing in response to market conditions, no replacement of underperforming holdings, and no adjustment of the portfolio's composition based on economic developments or changes in the issuer's fundamental prospects. The UIT is a pure buy-and-hold vehicle — its investment thesis is expressed entirely in the initial portfolio selection and then maintained passively until termination. The UIT indenture may permit the trustee to sell a security under specific limited circumstances — typically when the issuer defaults, becomes insolvent, or experiences a credit rating downgrade below a specified minimum — but these are narrow exceptions rather than ongoing management discretion.

The absence of a board of directors is the second defining characteristic — UITs are not organised as corporations and have no governing board with fiduciary oversight responsibilities over investment decisions. The trust is governed by its indenture — the contractual document establishing the trust's terms and the trustee's obligations — rather than by a board that could exercise discretion over the portfolio. The trustee's role is administrative and custodial rather than managerial — the trustee holds the portfolio securities, collects income, makes distributions to unitholders, and ensures compliance with the trust indenture's terms, but makes no investment decisions.

The termination date is the third defining characteristic — every UIT has a specified date at which the trust will dissolve and distribute the proceeds of liquidating the remaining portfolio to unitholders. UIT termination dates range from fifteen months for short-term bond UITs to fifty or more years for very long-term equity UITs — with most equity UITs structured with fifteen-to-twenty-four month terms that are frequently rolled over by sponsors offering successor trusts. At termination the trustee liquidates the portfolio's remaining securities and distributes the net proceeds to unitholders — the trust ceases to exist and unitholders receive cash rather than continuing to hold units in an ongoing investment vehicle.

The one-time public offering of a fixed number of units is the fourth defining characteristic — distinguishing the UIT from the open-end mutual fund which continuously creates new shares as new investors purchase and redeems shares as investors sell. The UIT sponsor assembles the portfolio, determines the total number of units to be offered, files the registration statement with the SEC, and conducts a single public offering of those units. Once all units are sold no new units are created — the trust is closed to new investment from that point forward except through secondary market purchases.

The Sponsor, Trustee, and Evaluator — The Operating Structure

Despite the absence of a board of directors and active portfolio management, the UIT involves several distinct parties with defined roles in the trust's operation.

The sponsor — typically an investment banking firm or a broker-dealer — is the organiser of the UIT. The sponsor selects the portfolio, assembles the trust, files the registration statement with the SEC, underwrites the initial public offering of units, and typically maintains a secondary market allowing existing unitholders to sell their units and new investors to purchase units after the initial offering is complete. Many UIT sponsors also assemble successor trusts — new UITs with similar investment objectives that are offered to investors whose existing UIT is approaching its termination date, allowing investors to roll their proceeds into a continuation of the strategy.

The trustee — typically a bank or trust company — holds legal title to the portfolio securities in custody, collects dividends and interest income from the portfolio, makes distributions to unitholders, handles corporate actions affecting portfolio securities, and maintains the administrative records of the trust. The trustee acts under the authority of the trust indenture and has no discretion over investment decisions — the trustee's role is purely custodial and administrative.

The evaluator — sometimes the same entity as the trustee or sponsor — is responsible for determining the net asset value of the UIT's portfolio at regular intervals — typically daily — by pricing each security in the fixed portfolio at its current market value, summing the total, deducting any accrued expenses and liabilities, and dividing by the total number of outstanding units to produce the per-unit NAV at which units may be redeemed.

Redemption — How Investors Exit UIT Positions

Unlike closed-end fund shares which trade in the secondary market at prices that may differ from NAV, UIT units are redeemable — investors who wish to sell their units can redeem them directly with the sponsor or trustee at the current NAV minus any applicable redemption fee. This redeemability makes the UIT structurally similar to the open-end mutual fund in terms of exit mechanics — the investor is guaranteed to receive approximately NAV upon redemption rather than being subject to the market price discount that closed-end fund shareholders may face.

Many UIT sponsors also maintain a secondary market in the units they have sponsored — offering to repurchase units from existing holders and resell them to new investors, providing a convenience mechanism for investors who want to sell their units without triggering a full redemption from the trust. In the sponsor's secondary market units may trade at a slight premium or discount to NAV depending on supply and demand conditions, but the existence of the redemption option at NAV effectively prevents any large or persistent discount from developing.

The Two Primary Categories — Equity UITs and Bond UITs

UITs are assembled in two primary portfolio categories — equity UITs holding stocks and bond UITs holding fixed income securities — each serving distinct investor objectives and carrying different risk and income characteristics.

Equity UITs assemble portfolios of common stocks selected according to a specific investment theme or strategy — dividend income strategies, sector-specific strategies such as technology or healthcare concentrations, strategies tracking specific indices or index components, or strategies based on quantitative screening criteria. As of year-end 2024 equity trusts comprised approximately ninety-five percent of UIT assets — a dramatic shift from the historical dominance of bond UITs that reflected the growth of equity-oriented UIT strategies during the sustained bull market of the past several decades. The SPDR S&P 500 ETF Trust — ticker SPY — the most actively traded ETF in the world — is technically structured as a UIT under the Investment Company Act of 1940, making the UIT structure historically significant even in the modern ETF era.

Bond UITs assemble portfolios of fixed income securities — municipal bonds, corporate bonds, government bonds, or mortgage-backed securities — selected to provide regular income distributions throughout the trust's life. Bond UITs were historically among the most popular retail investment products because they provided access to diversified bond portfolios at minimum investment sizes well below the one thousand dollar or five thousand dollar minimum denominations of individual bonds, allowing small investors to obtain diversified fixed income exposure through a professionally assembled portfolio. The defined maturity structure of bond UITs — in which the bonds in the portfolio mature at or before the trust's termination date — gives bond UITs a more predictable terminal value than equity UITs whose portfolio values depend on market conditions at termination.

Cost Structure — Sales Charges and Ongoing Expenses

UITs are subject to sales charges and ongoing expenses that investors must understand before purchasing — and that investment advisers must evaluate under the fiduciary duty of the Investment Advisers Act of 1940 when assessing whether a UIT is appropriate for a specific client.

The initial sales charge — charged at the time of purchase — typically ranges from one to three point five percent of the public offering price for equity UITs and from one to four percent for bond UITs, depending on the investment amount, with breakpoints that reduce the percentage charge for larger purchases. The creation and development fee — sometimes called the C&D fee — is an additional charge assessed at the time of purchase that compensates the sponsor for the cost of assembling the trust and is not subject to the breakpoint schedule that reduces the initial sales charge.

Ongoing annual expenses — including trustee fees, evaluator fees, and supervisory fees — are assessed against the trust's assets throughout its life and are disclosed in the prospectus. Because the UIT has no investment adviser making ongoing portfolio decisions, its ongoing expense structure is typically lower than that of actively managed mutual funds — the absence of an advisory fee is a meaningful cost advantage for the UIT relative to actively managed alternatives, though the upfront sales charge structure must be considered in the total cost comparison.

The UIT Versus the Mutual Fund Versus the Closed-End Fund — The Critical Comparison

The three-way comparison among UITs, open-end mutual funds, and closed-end funds is among the most directly and consistently tested topics in the Series 65 examination's investment company curriculum — because the three structures share some surface similarities while differing in fundamental ways that determine their appropriate use for different investor objectives.

An open-end mutual fund continuously creates new shares as investors purchase and redeems shares as investors sell — its share count fluctuates constantly with investor flows. It is actively managed by a portfolio manager who continuously makes buy and sell decisions — the portfolio changes constantly. Shares are redeemable at NAV calculated at the end of each trading day. The fund has an indefinite life with no termination date. It has a board of directors exercising oversight over the portfolio manager.

A closed-end fund issues a fixed number of shares in a one-time IPO and then those shares trade in the secondary market on a national exchange — the fund does not continuously issue or redeem shares. It is actively managed by a portfolio manager. Its shares trade at market prices that may be at a premium or discount to NAV — sometimes substantial and persistent discounts. The fund has no termination date and an indefinite life. It has a board of directors.

A UIT issues a fixed number of units in a one-time public offering — like a closed-end fund — but its units are redeemable at NAV rather than trading in the secondary market — like a mutual fund. It has no portfolio manager and no ongoing investment decisions — the portfolio is fixed at creation. It has a specified termination date — unlike both mutual funds and closed-end funds. It has no board of directors — unlike both mutual funds and closed-end funds.

What the Trust Indenture Must Provide About the Trustee

Section 26(a) of the Investment Company Act of 1940 makes the content of the trust indenture the condition of distributing the units at all — no principal underwriter for, or depositor of, a registered unit investment trust may sell any security of which the trust is the issuer, other than short-term paper, unless the instrument under which that security is issued contains the provisions the subsection sets out. The first of those provisions designates one or more trustees or custodians, each of which must be a bank, and requires that each hold at all times an aggregate capital, surplus and undivided profits of a specified minimum amount, which the statute provides shall not be less than five hundred thousand dollars — so the party holding the portfolio is a capitalised banking institution rather than whatever entity the sponsor finds convenient. Where that trustee or custodian publishes reports of condition at least annually, under law or under the requirements of its supervising or examining authority, the instrument may provide that its capital, surplus and undivided profits are taken for this purpose from its most recent published report of condition.

The indenture must also fix how the trustee is paid, and in what order. It must provide, in substance, that during the life of the trust a trustee or custodian that is not otherwise remunerated may charge against and collect from the income of the trust the fees for its services and the reimbursement of its expenses that the instrument provides for, and may reach the corpus of the trust only if no income is available. The ordering is what the provision is for: expenses are met first out of what the portfolio earns, and the principal the units represent is drawn on only when those earnings do not cover them.

A further provision governs the timing of those charges. The instrument must provide, in substance, that no such charge or collection shall be made except for services already performed or expenses already incurred — so the trustee bills backwards, against work done and money spent, rather than forwards against work promised for the remainder of the trust's term.

Custody, Payments to Affiliated Parties, and the Trustee's Succession

The same subsection closes the route by which the trust's own assets could find their way back to the parties that organised it. The instrument must provide, in substance, that no payment to the depositor of the trust, to a principal underwriter for it, or to any affiliated person or agent of that depositor or underwriter, shall be allowed the trustee or custodian as an expense. One carve-out is permitted: provision may be made for paying such a person a fee, not exceeding the reasonable amount the Commission may prescribe, as compensation for performing bookkeeping and other administrative services of a character normally performed by the trustee or custodian itself.

The instrument must also put the property itself beyond the sponsor's reach. It must provide, in substance, that the trustee or custodian shall have possession of all securities and other property in which the funds of the trust are invested, all funds held for such investment, all equalisation, redemption and other special funds of the trust, and all income upon, accretions to and proceeds of that property and those funds — and shall segregate and hold the same in trust, subject only to the charges and collections the preceding clauses allow, until it is distributed to the security holders of the trust.

Because the portfolio is held for a term fixed in advance rather than managed, the continuity of the custodian matters as much as its identity. The instrument must provide, in substance, that the trustee or custodian shall not resign until either the trust has been completely liquidated and the proceeds of the liquidation distributed to the security holders of the trust, or a successor trustee or custodian having the qualifications the subsection prescribes has been designated and has accepted the trusteeship or custodianship. Those are the only two exits the provision allows, so there is no moment in the life of a registered trust at which the portfolio is in nobody's custody.

Substituting a Portfolio Security, and the Record of Unitholders

Where a registered unit investment trust holds the security of a single issuer, Section 26(c) makes it unlawful for the depositor or the trustee of that trust to substitute another security for that security unless the Commission has approved the substitution, and provides that the Commission shall issue an order approving it if the evidence establishes that the substitution is consistent with the protection of investors and the purposes fairly intended by the policy and provisions of the subchapter. Two features of that wording repay attention: the approval is not discretionary once the evidentiary standard is met, and the standard is addressed to the protection of investors rather than to the relative merits of the two securities as investments.

A substitution that does take place must be reported to the holders whose interests it changes. The instrument must provide, in substance, that whenever a security is deposited with the trustee in substitution for any security in which a security holder has an undivided interest, the depositor or the agent of the depositor will, within five days after that substitution, either deliver or mail to that security holder a notice of substitution — including an identification of the securities eliminated and the securities substituted, and a specification of the shares of that security holder affected by the substitution.

That notice presupposes a list of people to send it to, and the instrument must provide for one. A record is to be kept by the depositor, or by an agent of the depositor, of the name and address of every holder of any security issued under the instrument and of the shares issued by the trust and held by that holder, insofar as that information is known to the depositor or the agent. The qualification is part of the obligation rather than a weakening of it: the record is as complete as the information actually reaching the depositor and its agent makes it.

The Selling Restriction, and Curing an Instrument That Falls Short

The sanction Section 26(a) attaches to a non-complying instrument is worth stating precisely, because it is not the one a reader expects. The subsection does not void the trust, disqualify the trustee or unwind the portfolio — it provides that no principal underwriter for, or depositor of, a registered unit investment trust shall sell any security of which the trust is the issuer unless the instrument contains the required provisions. The consequence of a defective indenture therefore falls on distribution, and it falls on the two parties the prohibition names, who are the parties that would place the units.

The prohibition is a prohibition on selling, and it carries an express exception for surrender to the trustee for redemption. A holder's route out of the trust is accordingly not closed by the same defect that stops the units being sold — the instrument's shortcomings bear on bringing new money in rather than on letting existing money out.

Nor is a defective instrument beyond repair. Section 26(d) provides that where a trust indenture, agreement of custodianship or other instrument under which the securities of a registered unit investment trust are issued does not comply with the requirements of subsection (a), that instrument will be deemed to meet those requirements if a written contract or agreement binding on the parties and embodying those requirements has been executed by the depositor on the one part and the trustee or custodian on the other, and copies of that contract or agreement have been filed with the Commission. The requirements are thus treated as substance that must be binding somewhere between depositor and trustee, rather than as language that must appear in one particular document.

Liquidating a Trust the Commission Believes Is Inactive

A trust that has gone inactive can be wound up on the Commission's initiative rather than the sponsor's. Section 26(e) provides that whenever the Commission has reason to believe that a unit investment trust is inactive and that its liquidation is in the interest of the security holders of that trust, the Commission may file a complaint seeking the liquidation of the trust in the district court of the United States in any district where any trustee of the trust resides or has its principal place of business.

The procedure is adversarial rather than administrative. A copy of the complaint is to be served on every trustee of the trust, and notice of the proceeding is to be given to such other interested persons in such manner and at such times as the court may direct. Read together with the venue provision, this means each trustee of the trust is at once a possible basis for the choice of court and a party entitled to be served.

The decision itself is the court's. If the court determines that the liquidation is in the interest of the security holders of the trust, it shall order the liquidation and, after payment of necessary expenses, the distribution of the proceeds to the security holders in such manner and on such terms as may to the court appear equitable. The Commission's belief is therefore what starts the proceeding while the court's determination is the condition of the remedy, and what reaches the holders is what is left once the necessary expenses have been paid.

How Units Leave the Trust, and What That Does to Its Size

Two features of the structure work in opposite directions on the size of the trust. The units are redeemable, so a holder who surrenders units to the trustee takes value out of the trust; and once all units are sold no new units are created, so nothing puts value back. The number of units outstanding in a unit investment trust can therefore only fall across the trust's life, where an open-end fund's share count moves in both directions as investors buy and sell and a closed-end fund's moves in neither.

That is what makes the sponsor's secondary market more than a convenience. When a holder sells units to the sponsor instead of surrendering them to the trustee, the units are not retired: the sponsor holds them and resells them to a new investor, and the trust's unit count and its portfolio are untouched by the transaction. A sponsor that maintains an active secondary market in the trusts it has sponsored therefore slows the contraction of those trusts, because the sales that pass through it never reach the trustee as redemptions at all.

The termination date belongs to the trust rather than to the holder, and it is fixed when the trust is assembled rather than running from the date on which any particular holder buys. A buyer in the sponsor's secondary market therefore acquires a shorter remaining term than the original subscriber did, and the difference is simply the time the trust has already run: units of a trust assembled with a twenty-four month term, bought once nineteen of those months have run, carry twenty-four minus nineteen, or five months, to termination rather than twenty-four. Two investors holding identical units can accordingly face quite different horizons, because the horizon is a property of the trust's calendar and not of the purchase.

What the Holder Is Relying On, and Where the Distributions Come From

Because the portfolio is selected when the trust is assembled and is not revisited, the act of judgement a unitholder relies on is complete before any unit is sold. There is no later decision to assess, no sequence of subsequent decisions to compare against a benchmark, and nothing in the trust's ordinary operation that can either improve on the original selection or depart from it — so the published portfolio is the whole of what the units represent for the life of the trust, and the sponsor's judgement is a thing assessed on one occasion rather than continuously.

The same fixity shapes the income. A bond trust's distributions come from the coupons of the bonds chosen at assembly, and because no replacement security is bought when a holding matures or defaults, the income the trust pays falls as those events occur rather than being restored by reinvestment. The distribution a holder receives in the trust's later years can therefore be smaller than the distribution in its early years with nothing whatever having gone wrong — the schedule of the portfolio's own maturities is enough on its own to produce the decline.

The ordering of the trustee's charges has a consequence the holder feels in the unit value. Because Section 26(a)(2)(A) requires the instrument to let the trustee charge against the income of the trust and reach the corpus only if no income is available, a trust whose portfolio income falls short of the fees and expenses its instrument provides for meets the shortfall out of principal — and principal spent on expenses is principal that is not there to be distributed. Suppose a trust's instrument provides for charges of twenty basis points of assets a year and its portfolio yields five basis points: the first five basis points are met out of income and the remaining fifteen come out of the corpus, so the per-unit value falls by fifteen basis points over the year even if the prices of every holding are unchanged.

Separate Accounts Funding Variable Insurance Contracts — The Exemption in Section 26

Section 26 carries an exemption in its subsection (f) for one kind of registered account. Subsection (a) — the whole of the indenture requirement described above — does not apply to any registered separate account funding variable insurance contracts, or to the sponsoring insurance company and principal underwriter of such an account. The provisions that govern the instrument of an ordinary registered trust are therefore switched off for that account, and the paragraphs that follow substitute a different set of conditions in their place.

What takes their place is a restriction on selling expressed as a test of the contract's charges. Subsection (f)(2) makes it unlawful for a registered separate account funding variable insurance contracts, or for the sponsoring insurance company of such an account, to sell any such contract unless the fees and charges deducted under the contract are, in the aggregate, reasonable in relation to the services rendered, the expenses expected to be incurred and the risks assumed by the insurance company, and the insurance company so represents in the registration statement for the contract. For the purposes of that test the fees and charges deducted under the contract include all fees and charges imposed for any purpose and in any manner, so the test cannot be escaped through the label a charge is given or the mechanism by which it is taken.

The same paragraph attaches further conditions that put the insurance company in the trustee's position and lean on its state insurance regulator. Selling such a contract is also unlawful unless the insurance company complies with all the other applicable provisions of Section 26 as if it were a trustee or custodian of the registered separate account; files with the insurance regulatory authority of the State that is its domiciliary State an annual statement of its financial condition whose most recent version shows a combined capital and surplus, if it is a stock company, or an unassigned surplus, if it is a mutual company, of not less than one million dollars, or such other amount as the Commission may from time to time prescribe by rule; and, together with its registered separate accounts, is supervised and examined periodically by the insurance authority of that State. That million-dollar figure is the floor the statute itself sets and is expressly subject to any other amount the Commission prescribes, so it is a statutory minimum rather than a fixed requirement.

Examination Relevance and Key Takeaways

The unit investment trust is tested on the Series 65 examination in the context of the three registered investment company categories under the Investment Company Act of 1940, the UIT's structural characteristics, and the comparison with mutual funds and closed-end funds.

The key points to retain are these.

A unit investment trust is one of the three registered investment company types under the Investment Company Act of 1940 — alongside open-end funds and closed-end funds — defined in Section 4(2) as organised under a trust indenture issuing only redeemable securities representing undivided interests in a unit of specified securities. The four defining structural characteristics are a fixed unmanaged portfolio selected at creation and held substantially unchanged until termination — no ongoing buy and sell decisions by any portfolio manager; no board of directors — the trust is governed by its indenture and administered by a trustee with no investment discretion; a specified termination date at which the trust dissolves and distributes proceeds to unitholders; and a one-time public offering of a fixed number of units — no continuous creation of new units as with open-end mutual funds.

The three parties are the sponsor — who assembles the portfolio and underwrites the offering; the trustee — who holds securities in custody and administers the trust with no investment discretion; and the evaluator — who calculates daily NAV. Units are redeemable at NAV — providing the exit mechanism of a mutual fund — but the fixed unit count resembles a closed-end fund. Many sponsors maintain secondary markets in their UIT units. The two primary categories are equity UITs — comprising approximately ninety-five percent of UIT assets as of year-end 2024 — and bond UITs. The SPDR S&P 500 ETF — SPY — is technically structured as a UIT under the Investment Company Act of 1940. The critical examination comparison — UIT versus mutual fund — UITs have fixed portfolios with no active management, no board of directors, specified termination dates, and one-time offerings of fixed unit counts while mutual funds continuously create and redeem shares, are actively managed, have boards of directors, and have indefinite lives. UIT versus closed-end fund — both have fixed unit or share counts from a one-time offering but UITs issue redeemable units at NAV while closed-end fund shares trade at market prices that may differ from NAV, and UITs have no active management or board while closed-end funds have both.
