Trust preferred securities, often shortened to TruPS, are hybrid instruments that a company issues through a special-purpose trust so that the payments look and trade like preferred stock dividends to investors but count as deductible interest on subordinated debt for the company. Bank holding companies were the heaviest issuers from the mid-1990s until the 2008 financial crisis, when the Dodd-Frank Act removed most of the regulatory reason to issue them. Legacy TruPS from smaller banks and some non-bank corporations still trade, and understanding how the structure works is the key to reading one on a brokerage screen.
How the Structure Works
A TruPS transaction has three parties: a parent company, a wholly owned trust the parent creates for this one purpose, and outside investors. The trust is a statutory business trust with no independent operations. Its job is to sell preferred securities to the public and hand the cash to the parent.
The trust uses every dollar it raises to buy junior subordinated debentures from the parent. Those debentures are the trust’s only real asset. The parent pays interest on the debentures, and the trust passes that interest straight through to investors as distributions. Cash flows in a loop: investors to trust, trust to parent, parent back through the trust to investors.
The structure exists because of the arbitrage it creates. The parent books the transaction as debt and deducts the payments as interest. Investors hold something that trades like preferred stock. The trust in the middle is a pass-through.
Debt and Equity Features in One Security
The “hybrid” label describes a security that borrows from both sides of the capital structure.
On the equity side, TruPS are deeply subordinated. In a liquidation, holders are paid only after senior lenders and bondholders. The underlying junior subordinated debenture is senior only to the parent’s common stock and traditional preferred stock. Holders have no voting rights in the parent company.
On the debt side, TruPS have a fixed maturity, typically at least 30 years from issuance and sometimes as long as 50. They pay a fixed or floating rate on a regular schedule, like bond coupons. The issuer must eventually repay principal. Distributions are cumulative, so any skipped payments must be made up in full, with compound interest on the missed amounts.
The Parent Company Guarantee
The parent doesn’t just owe money to the trust on the debentures. It also guarantees the trust’s obligations directly to investors, covering interest, principal, and other amounts owed under the indenture. This is a guarantee of payment rather than of collection, so investors don’t have to exhaust remedies against the trust before pursuing the parent.
The guarantee itself is subordinated to the parent’s senior debt. In a bankruptcy, it sits in the same low-priority position as the underlying debentures.
How Distributions Are Taxed
Because TruPS distributions flow from interest on subordinated debentures, the IRS treats them as interest income, not qualified dividends. They are reported on Form 1099-INT or Form 1099-OID rather than Form 1099-DIV, and they are taxed at ordinary income rates rather than the lower qualified dividend rate.
The more painful tax result appears during a deferral. If the issuer suspends distributions (the terms allow up to five years), investors may still owe tax on interest that accrues but hasn’t been paid. The IRS treats that accruing interest as taxable in the year it accrues, whether cash changes hands or not. Investors get a tax bill and no cash to pay it. The S&P Global practice guide on U.S. preferreds flags this as a risk that “really needs to be understood” before buying trust preferreds.
Deferral Rights and the Five-Year Limit
One of the more distinctive features of TruPS is the issuer’s ability to defer distributions. Payments can be stopped for up to 20 consecutive quarters, or five years, without triggering a default, provided the parent also halts common stock dividends during the deferral. Interest continues to accrue and compound the whole time, so investors are entitled to the full amount eventually, but the cash flow gap can be severe.
If the issuer fails to resume payments after that 20-quarter window, the deferral converts into an event of default and acceleration. Investors gain the right to seize the subordinated debenture held by the trust, and the parent’s obligation to pay principal plus all accrued interest becomes immediately due. In practice, a company that can’t resume distributions after five years is usually in deep trouble, so the acceleration right may matter more on paper than in the actual recovery.
Why New Issuance Largely Stopped
Banking regulators originally let TruPS count toward Tier 1 capital, the core measure of a bank’s financial strength. That treatment paired with the interest deduction is what made the instrument so attractive to bank holding companies. The 2008 financial crisis changed the calculation. TruPS had been packaged into collateralized debt obligations that concentrated risk among community banks, and the losses that followed pushed regulators to reassess whether these instruments truly absorbed losses the way equity should.
The Dodd-Frank Act of 2010 addressed this through Section 171, codified at 12 U.S.C. ยง 5371. The statute drew lines by issue date and institution size:
- Any TruPS issued on or after May 19, 2010 immediately lost eligibility as Tier 1 capital for all depository institution holding companies.
- For TruPS issued before May 19, 2010 by large institutions with $15 billion or more in assets, capital deductions were phased in over three years beginning January 1, 2013.
- Holding companies with total consolidated assets below $15 billion as of December 31, 2009 or March 31, 2010 were exempt from the capital deductions required by this section for their pre-existing TruPS.
Large banks responded with a wave of early redemptions, calling their outstanding TruPS rather than holding instruments that no longer counted toward capital. By the end of 2016, most large U.S. bank TruPS had been redeemed. New issuance has effectively dried up, though legacy TruPS from smaller institutions and from some non-bank corporations (where the Tier 1 question never applied) remain outstanding.
Risks in Legacy TruPS Still Trading
Beyond the phantom income problem during a deferral, several risks are worth attention for anyone looking at TruPS on the secondary market.
Interest Rate Risk
With maturities of 30 years or longer, TruPS carry substantial interest rate sensitivity. When market yields rise, the fixed payments on existing TruPS become less attractive relative to new instruments, and prices drop. The same dynamic affects long-duration bonds, but the effect is amplified by the extreme length of these maturities. Investors who need to sell during a rising-rate stretch can face significant losses.
Call Risk
Most TruPS include call provisions that let the issuer redeem the securities early, often at par. Regulatory changes and tax law changes are common triggers written into the terms; the Dodd-Frank phase-out was the largest call trigger in the instrument’s history. For an investor who bought at a premium in the secondary market, an early call at par means a capital loss even if every distribution arrived on schedule.
Liquidity and Credit Risk
Retail-oriented TruPS typically trade on exchanges with par values around $25, which makes them accessible to individual investors. Institutional TruPS are denominated at $1,000 par and trade over the counter, where liquidity can be thin. In either case, the secondary market has shrunk considerably as issuers have redeemed outstanding securities. Credit risk is also meaningful, because TruPS sit near the bottom of the capital structure and absorb losses before senior creditors in any restructuring or bankruptcy.
Reading a TruPS Before You Buy
The remaining TruPS in the market are a niche income-producing asset class with above-average yields that reflect the subordination, illiquidity, and complexity built into the structure. Anyone considering a purchase should read the prospectus carefully, paying particular attention to the deferral terms, the call provisions, and the specific guarantee language backing the securities. Those three sections determine what actually happens to your cash flow and your principal if the issuer runs into trouble or the rate environment shifts.
