Ex-Dividend Dates, Due Bills, Corporate Actions & Reg T Margin on the Series 99 Exam

Key Takeaways

  • The shift to T+1 settlement moved the ex-dividend date to the business day after the record date, a critical change you must master.
  • A due bill is required when a trade executed cum-dividend (before the ex-date) settles after the record date, a scenario now common in non-regular-way settlements.
  • Regulation T's payment deadline for margin purchases is now T+3 (Trade Date + 3 business days), a direct consequence of the T+1 settlement cycle.
  • The most difficult exam questions integrate these concepts, testing your ability to track a single trade through a corporate action, dividend cycle, and its margin implications under T+1 rules.

Most Series 99 candidates who fail questions on dividends do so for the same reason: they are studying outdated T+2 settlement rules. The 2024 shift to T+1 settlement fundamentally changed how ex-dividend dates work, and rote memorization of the old date sequence is now a direct path to a wrong answer. The real test is not if you can list the four dates, but if you can apply the new logic to a trade that settles across them.

Quick answer

For the 2026 Series 99 exam, the T+1 settlement cycle means the ex-dividend date is now typically the business day after the record date. This change impacts when due bills are created and how Regulation T payment deadlines are calculated (now T+3). Success requires applying this new post-2024 operational reality, not outdated rules.

How Did the T+1 Shift Change Ex-Dividend Dates?

The ex-dividend date is the first day a stock trades without the right to a declared dividend, and its timing is now governed by the T+1 settlement cycle effective since May 28, 2024. This rule change, amending SEC Rule 15c6-1(a), is the single most important update for this topic.

Under the new T+1 regime, the sequence of dates has been reordered.

Step 1: Declaration Date

The company's board of directors announces the dividend. This is the start of the process.

Step 2: Record Date

The company determines who owns the stock on its official records. To receive the dividend from the issuer, you must be the owner of record on this date.

Step 3: Ex-Dividend Date

Set by FINRA, this is now typically one business day after the record date. This is the market cutoff. If you buy the stock on or after the ex-dividend date, you will not get the dividend.

Step 4: Payable Date

The company sends the dividend payment to all shareholders of record.

This reordering is a massive trap for anyone studying old material. Under the previous T+2 system, the ex-date was before the record date. Now, it is after.

Exam trap: The most common wrong answer stems from applying the old T+2 logic. Candidates mistakenly believe the ex-dividend date is still one day before the record date. On the exam, if the record date is Tuesday the 10th, they will incorrectly choose Monday the 9th as the ex-date. The correct answer for 2026 is Wednesday the 11th. This single fact can decide several questions.

When Is a Due Bill Required Under T+1 Rules?

A due bill is an instrument used by a broker-dealer to claim a dividend for a buyer who was entitled to it but did not receive it from the issuer. This happens when a trade is executed cum-dividend (before the ex-dividend date), but the trade settles after the record date.

Because regular-way T+1 trades settle so quickly, this scenario is now less common for standard trades. However, the exam will test you on situations where settlement is delayed, such as "seller's option" contracts or trade fails.

Worked example: Scenario: ZYX Corp declares a $0.50 per share dividend.
  • Declaration Date: Monday, July 1
  • Record Date: Thursday, July 11
  • Ex-Dividend Date: Friday, July 12 (one business day after record date)
  • Payable Date: Friday, July 26
Trade: On Wednesday, July 10, a customer buys 1,000 shares of ZYX from a seller using a "seller's option" contract, with settlement scheduled for Monday, July 15. Analysis:
  1. Trade Date: July 10. This is before the ex-dividend date of July 12, so the trade is cum-dividend. The buyer is entitled to the dividend.
  2. Record Date: July 11.
  3. Settlement Date: July 15. This is after the record date.
  4. Who gets paid by the issuer? Because the trade has not settled by the record date, the seller is still the owner on the company's books. ZYX Corp will send the dividend of $500 (1,000 shares x $0.50) to the seller.
Due Bill Action: The buyer was entitled to the dividend but the seller received it. The seller's firm is now obligated to deliver the $500 to the buyer's firm. This is accomplished by attaching a due bill to the transaction, ensuring the buyer is made whole.

This example shows why simply memorizing dates is not enough. You must trace the ownership and settlement flow to identify the need for operational corrections. Test your judgment on dozens of T+1 scenarios with VoraPrep's adaptive question bank.

What Are Your Responsibilities for Corporate Actions?

Corporate actions are company events that affect its securities and shareholders, requiring precise operational handling. The Series 99 exam requires you to know the difference between mandatory and voluntary actions and the specific steps your firm must take for each.

FeatureMandatory Corporate ActionsVoluntary Corporate Actions
DescriptionEvents that automatically apply to all shareholders. No choice is involved.Events where shareholders must decide whether to participate.
ExamplesStock splits, cash dividends, mergers, spin-offs.Tender offers, rights offerings, exchange offers.
Operational DutyAutomatically adjust client accounts: update share counts, cost basis, and cash.Notify clients, explain their options, collect instructions, and meet deadlines.
Primary RiskInaccurate processing, such as miscalculating a new cost basis after a reverse split.Missing a client's election deadline, resulting in a financial loss or missed opportunity.

For a mandatory 3-for-2 stock split, your operations department must ensure a client holding 100 shares now shows 150 shares, and the original cost basis is reallocated across the new share count. For a voluntary tender offer, you must deliver the offering documents to the client and process their decision to tender or hold their shares before the offer expires.

How Does Regulation T Work with T+1 Settlement?

Regulation T from the Federal Reserve Board governs the extension of credit by broker-dealers for securities purchases. For margin accounts, it sets the initial deposit requirement (typically 50% for equities) and the payment deadline.

The T+1 settlement shift directly impacts the payment deadline. The rule requires payment from the customer no later than two business days after the settlement date (S+2).

  • Old Rule (T+2): Settlement was T+2, so payment was due on T+2 + 2 days = T+4.
  • New Rule (T+1): Settlement is T+1, so payment is due on T+1 + 2 days = T+3.

If a customer fails to pay by the T+3 deadline, the firm must either request a payment extension from FINRA or liquidate the securities and freeze the account for 90 days, which prevents "free riding."

Formula: Regulation T Margin Payment (2026 Rules) Scenario: A customer buys 100 shares of ABC at $80 per share in a margin account on Monday, October 6, 2026.
  1. Total Purchase: 100 shares * $80/share = $8,000
  2. Reg T Initial Requirement: $8,000 * 50% = $4,000
  3. Payment Due Date Calculation:
  • Trade Date (T): Monday, October 6
  • Settlement Date (T+1): Tuesday, October 7
  • Payment Due (S+2 or T+3): Thursday, October 9

The customer must deposit the $4,000 by the close of business on Thursday, October 9. This accelerated timeline is a direct result of T+1 and a frequent source of exam questions. Understanding this calculation is essential for anyone serious about passing. For a full breakdown of all exam topics, see the VoraPrep Series 99 course outline.

How to Prepare for Integrated Scenario Questions

The hardest Series 99 questions don't test these topics in isolation. They weave them together into a single operational problem. You might see a question about a margin purchase of a stock that undergoes a reverse split right before its ex-dividend date, with a delayed settlement.

Your job is to untangle it methodically.

  1. Timeline First: Always map out the dates: Trade, Settlement, Record, and Ex-Dividend.
  2. Apply Corporate Action: Adjust the share count and price based on any split, merger, or other action.
  3. Check Dividend Entitlement: Use the trade date vs. the ex-dividend date to see who is owed the dividend.
  4. Check Settlement: Compare the settlement date to the record date to see if a due bill is needed.
  5. Apply Margin Rules: Calculate any Reg T requirements and payment deadlines based on the trade date.

Frequently asked questions

What is the new rule for the ex-dividend date on the Series 99 exam for 2026?

Following the shift to T+1 settlement in 2024, the ex-dividend date for equities is now typically set for the first business day after the record date. This is a reversal of the old T+2 rule and a critical concept to know for the exam.

Do due bills still exist with T+1 settlement?

Yes, due bills are still relevant and testable. They are required when a trade executed before the ex-dividend date (cum-dividend) settles after the record date. While less common in regular-way trades, this occurs in scenarios with delayed settlement, like seller's option contracts or trade fails.

What is the Regulation T payment deadline for margin accounts in 2026?

Under T+1 settlement, the Regulation T payment deadline is now three business days after the trade date (T+3). This is calculated as the settlement date (T+1) plus two additional business days (S+2).

How should I study for Series 99 scenario questions?

The best way to study is to practice integrated problems. For any given scenario, create a timeline of all relevant dates (trade, settlement, record, ex-dividend). Then, methodically apply the rules for corporate actions, dividend entitlement, and margin requirements in that order to arrive at the correct operational outcome.
