FINRA Rule 11890 is the series-level marker for the third instance, within this dictionary's coverage, of the series-marker-within-a-series-marker pattern — following FINRA Rule 11360 (units of delivery) and FINRA Rule 11570 (certificates in various names) — organizing the four-rule Clearly Erroneous Transactions cluster that concludes the FINRA Rule 11800 Close-Out Procedures subsection. FINRA Rule 11890 has no operative text of its own under The Rule tab. However, its FINRA.org page directly displays two associated notices — Regulatory Notice 17-19, the T+2 settlement cycle conformity notice this dictionary has traced throughout its coverage of the settlement-cycle-dependent provisions, and Regulatory Notice 10-04, titled "SEC Approves Consolidated FINRA Rules Governing Clearly Erroneous Transactions," dated January 15, 2010 — a notice this dictionary has not previously encountered, and one that situates the origin of this entire cluster within the broader Consolidated FINRA Rulebook transfer this dictionary has traced through numerous December 15, 2010 amendments, but specifically as its own dedicated rule-filing approval (distinct from the more general SR-FINRA-2010-030 and SR-FINRA-2010-060 amendments this dictionary has encountered repeatedly). FINRA Rule 11890 organizes four child rules: FINRA Rule 11891, General; FINRA Rule 11892, Clearly Erroneous Transactions in Exchange-Listed Securities; FINRA Rule 11893, Clearly Erroneous Transactions in OTC Equity Securities; and FINRA Rule 11894, Review by the Uniform Practice Code ("UPC") Committee.
FINRA Rule 11890 sits within the 11800 Close-Out Procedures subsection of the 11000 Uniform Practice Code as the series-level marker for its final cluster, immediately following FINRA Rule 11880's settlement of syndicate accounts framework and immediately preceding FINRA Rule 11891, the first rule of the cluster it organizes.
A clearly erroneous transaction is a trade whose execution price (or, in some contexts, other terms) deviates so substantially from the prevailing market that the transaction is treated, under specific procedural rules, as not having validly occurred at its stated terms — typically resulting in the transaction being adjusted to a different price or canceled (nullified) entirely. This concept addresses a problem categorically different from the delivery-and-payment failures this dictionary has traced throughout FINRA Rules 11810 through 11880 — those rules address what happens when a validly-priced transaction fails to settle as agreed; the Clearly Erroneous Transactions cluster instead addresses what happens when the transaction's own terms (most centrally, its price) are themselves so anomalous that the transaction's validity is called into question from the outset.
FINRA Rule 11890's position as the final cluster within the FINRA Rule 11800 Close-Out Procedures subsection nonetheless makes structural sense. This dictionary has traced pricing-validity concerns at several points throughout its coverage — FINRA Rule 11170's settlement price formula for part-redeemed bonds, FINRA Rule 11740's marking-to-market mechanism for when, as and if issued/distributed contracts, and FINRA Rule 11810(d)(1)(D)'s requirement that members be prepared to defend the price at which a buy-in is executed relative to the current market. The Clearly Erroneous Transactions cluster represents the most direct and comprehensive treatment of price-validity questions this dictionary has encountered — addressing not merely how a price is calculated or defended in a specific remedial context, but whether a transaction's price is so anomalous that the transaction itself should be unwound.
Regulatory Notice 10-04's title — "SEC Approves Consolidated FINRA Rules Governing Clearly Erroneous Transactions" — and its January 15, 2010 date situate this cluster's origin within the broader Consolidated FINRA Rulebook project this dictionary has traced throughout its coverage, but as a notably earlier and more specifically-targeted approval than the December 15, 2010 SR-FINRA-2010-030/SR-FINRA-2010-060 amendments this dictionary has encountered repeatedly for individual rule transfers.
The consolidated framing suggests that, prior to this 2010 consolidation, clearly erroneous transaction rules may have existed in some more fragmented form — potentially with different standards applicable across different markets or contexts (consistent with FINRA Rule 11892's separate treatment of exchange-listed securities and FINRA Rule 11893's separate treatment of OTC equity securities) — with the 2010 consolidation bringing these various standards together into the unified FINRA Rule 11890 cluster this dictionary now examines. This dictionary cannot confirm the specific pre-consolidation history without examining FINRA Rules 11891 through 11894 directly, but notes Regulatory Notice 10-04's title and date as the relevant starting point for this cluster's modern framework.
FINRA Rule 11891's title — General — suggests this rule establishes foundational definitions and principles applicable across the cluster, paralleling the role this dictionary has observed for other "General Provisions"-titled rules, most directly FINRA Rule 11710 within the FINRA Rule 11700 subsection.
FINRA Rule 11892 and FINRA Rule 11893's parallel titles — Clearly Erroneous Transactions in Exchange-Listed Securities and Clearly Erroneous Transactions in OTC Equity Securities respectively — establish a market-structure-based bifurcation. This bifurcation directly parallels the kind of category-specific treatment this dictionary has observed throughout its coverage — FINRA Rule 11140(b)(3)'s separate ADR-and-foreign-securities treatment, FINRA Rule 11550(i)'s foreign-internal-securities carve-out, and most directly, FINRA Rule 11860(a)'s Clearing Agency framework, which itself addresses both exchange-cleared and OTC-context transactions. Exchange-listed securities trade on national securities exchanges with their own market-structure characteristics (specialists or designated market makers, exchange-specific trading rules, and so on), while OTC equity securities trade in the over-the-counter market without a single primary exchange — these structural differences plausibly warrant the separate treatment FINRA Rule 11892 and FINRA Rule 11893's titles suggest, with FINRA Rule 11891's General provisions presumably establishing whatever common framework applies across both contexts before each rule's category-specific provisions diverge.
FINRA Rule 11894's title — Review by the Uniform Practice Code ("UPC") Committee — directly invokes the UPC Committee this dictionary has traced throughout its coverage since FINRA Rule 11110, here in a review capacity specifically for clearly erroneous transaction determinations. This review function connects to the broader interpretive and dispute-resolution role this dictionary has observed the Committee perform — FINRA Rule 11110's general interpretations and rulings authority, FINRA Rule 11140(b)(3) and (c)'s ex-date designation authority, FINRA Rule 11810(g) and (i)'s extension and close-out-ruling authority, and now FINRA Rule 11894's review authority specifically for clearly erroneous transaction determinations made in the first instance under FINRA Rule 11892 or FINRA Rule 11893.
FINRA Rule 11890's display of Regulatory Notice 17-19 alongside Regulatory Notice 10-04 confirms that the Clearly Erroneous Transactions cluster — like FINRA Rules 11140, 11150, 11210, 11320, and 11620 — was amended as part of the 2017 T+2 settlement cycle conformity initiative. This connection makes sense given the cluster's pricing-validity focus — a clearly erroneous transaction determination necessarily involves comparing an executed price to the prevailing market price at a specific point in time, and the settlement cycle's length may bear on how such comparisons and any resulting price adjustments interact with the broader settlement timeline — though this dictionary will confirm the specific nature of this connection when examining FINRA Rules 11891 through 11894 directly.
Notably, Regulatory Notice 17-19 appears on FINRA Rule 11890's page without the corresponding Regulatory Notice 24-04 (the T+1 conformity notice) that this dictionary has seen accompany Regulatory Notice 17-19 for FINRA Rules 11140, 11150, 11210, 11320, and 11620. This absence may indicate that the Clearly Erroneous Transactions cluster's 2017 T+2 amendment was not subsequently revisited in the 2024 T+1 conformity wave — though this dictionary will note this observation for confirmation rather than asserting it as definitive without examining the individual child rules' own amendment histories.
FINRA Rule 11890 connects to FINRA Rule 11110 — whose UPC Committee FINRA Rule 11894's title explicitly names in a review capacity. It connects to FINRA Rule 11140, FINRA Rule 11150, FINRA Rule 11210, FINRA Rule 11320, and FINRA Rule 11620 — sharing Regulatory Notice 17-19's T+2 settlement cycle conformity connection, though without (so far as this entry can confirm) the corresponding T+1 Notice 24-04. It connects to FINRA Rule 11170 and FINRA Rule 11740 — whose pricing-determination frameworks (part-redeemed bond settlement price; mark-to-market) represent earlier instances of the pricing-validity concerns this cluster addresses comprehensively. It connects to FINRA Rule 11360 and FINRA Rule 11570 — as the third instance of the series-marker-within-a-series-marker pattern this dictionary has now traced across its coverage. It connects to FINRA Rule 11710 — as a structural parallel for FINRA Rule 11891's anticipated General-provisions role. It connects to FINRA Rule 11800 as its parent series marker, the final cluster within that subsection. It connects to FINRA Rule 11810(d)(1)(D) — whose price-defense documentation requirement for buy-ins represents an earlier, narrower instance of the price-validity concern this cluster addresses generally. And it connects to FINRA Rule 11860(a)(5) — whose Clearing Agency-based bifurcation of book-entry settlement responsibilities provides a structural parallel for the exchange-listed-versus-OTC bifurcation FINRA Rule 11892 and FINRA Rule 11893's titles establish.
FINRA Rule 11890 is tested on the Series 7 and Series 24 examinations as the series-level marker for the Clearly Erroneous Transactions cluster — the framework addressing transactions whose price (or other terms) deviates so substantially from the prevailing market that the transaction's validity is called into question, concluding the FINRA Rule 11800 Close-Out Procedures subsection.
The key points to retain are these: FINRA Rule 11890 has no operative text of its own, but its page displays two notices — Regulatory Notice 10-04 ("SEC Approves Consolidated FINRA Rules Governing Clearly Erroneous Transactions," January 15, 2010), marking this cluster's 2010 consolidation as a dedicated rule filing distinct from the broader SR-FINRA-2010-030/060 transfers this dictionary has traced elsewhere, and Regulatory Notice 17-19, the T+2 settlement cycle conformity notice; FINRA Rule 11890 organizes four child rules — FINRA Rule 11891 (General), FINRA Rule 11892 (Clearly Erroneous Transactions in Exchange-Listed Securities), FINRA Rule 11893 (Clearly Erroneous Transactions in OTC Equity Securities), and FINRA Rule 11894 (Review by the Uniform Practice Code ("UPC") Committee); a clearly erroneous transaction is one whose price deviates so substantially from the prevailing market that it may be adjusted or canceled under specific procedural rules — categorically distinct from the delivery/payment-failure remedies (buy-in, sell-out) this dictionary examined in FINRA Rules 11810 through 11880; the four-rule structure bifurcates by market structure (exchange-listed versus OTC equity securities) with general provisions and UPC Committee review as bookending elements; and this represents the third instance of the series-marker-within-a-series-marker pattern this dictionary has encountered, following FINRA Rule 11360 and FINRA Rule 11570.
