The 4.5% Series B preferred, trading under the symbol CTA-P-B, was issued April 15, 1947, carries a $100 liquidation preference, and last changed hands at $65.50, according to data reviewed on the security's listing page. That price reflects a discount of roughly 34.5% to par, translating into a current yield of 6.87% on the stock's fixed $4.50 annual dividend. A companion issue, the 3.5% Series A, trades under a related ticker and, per the same source material, sits at an even steeper discount to its own par value.\n\nWhat makes these instruments notable is less their yield than their structure. Both series are perpetual and cumulative, meaning EIDP is obligated to pay any missed dividends before it can pay common shareholders, but neither carries a fixed maturity date. The listing data shows the Series B stock as technically redeemable, yet with no confirmed call date attached: a status the page describes simply as \"redeemable (date n/a).\" That combination of cumulative protection, perpetual life, and an undefined call schedule was a common feature of preferred issuance in the mid-twentieth century, before corporate finance moved toward preferreds with hard call dates typically five to ten years after issuance.\n\nFor investors who hold or study these shares, the practical significance is that a security priced today reflects nearly 80 years of compounding uncertainty about if and when the issuer might ever redeem it at full par value. A $34.50 gap between the current price and the $100 liquidation preference represents, in principle, more than 52% of upside if the shares were ever called or redeemed at par, based on the figures shown on the listing page. But because no call date is confirmed, that gap can persist indefinitely, and the shares can continue trading purely on their income characteristics rather than any expectation of near-term redemption. The 52-week trading range on Series B, between $64.46 and $72.99, indicates the stock has moved within a relatively narrow band even as broader markets have swung sharply in recent sessions.\n\nThe discovery of these two securities' continued market presence first stood out in data tracked on Preferred Stock AI, a Madison Labs research site, which catalogs terms verified against SEC filings for both issues. Background on the broader preferred stock market helps frame why such instruments are unusual survivors: most legacy industrial preferreds from the postwar era have long since been called, converted, or retired as companies refinanced with cheaper capital or restructured balance sheets through mergers. DuPont's own corporate history includes a 2017 merger with Dow Chemical and subsequent business separations that produced entities including Dow Inc., Corteva, and DuPont de Nemours Inc., with EIDP remaining as the legal issuer tied to certain legacy obligations, including these preferred series.\n\nThe broader market backdrop on the day this data was captured showed pronounced weakness across risk assets: Bitcoin traded near $76,438, down 2.1% over 24 hours, while equities including Oracle, Palo Alto Networks, and Blackstone posted single-day declines exceeding 4%. That kind of volatility in growth-oriented and crypto assets stands in contrast to fixed-income-like instruments such as EIDP's preferred shares, whose price movements are typically driven more by interest-rate expectations and credit perceptions of the issuer than by daily sentiment swings in equities or digital assets.\n\nGoing forward, holders and market watchers of these securities are likely to focus on two variables: any corporate action from EIDP or its parent structure that might trigger redemption at par, and the broader interest-rate environment, since fixed-coupon perpetual preferreds tend to be sensitive to shifts in prevailing yields. No redemption announcement or call date has been confirmed as of the most recent filing verification referenced in the listing data. Absent such a development, these 1947-vintage instruments are positioned to keep trading as a rare, tangible link to a capital-raising era that predates most of today's corporate financing conventions.","source":{"name":"Preferred Stock AI","slug":"preferredstock-ai"},"category":"Preferred Stocks","article_type":"Data Story","license":"Free to republish, in full or in part, with attribution to SourceWire and a link to the original article.
