Regulation M Filings and Restricted-Period Notifications

Regulation M is the SEC's anti-manipulation regime for securities offerings. This unit covers the filing and notification mechanics: who is restricted, how long the restricted period runs, and which notices the manager (or, absent a manager, each participant) must file with FINRA. The substantive Reg M restrictions on stabilizing bids, syndicate covering, and short-selling around an offering belong to the next unit on execution and distribution.

How Do the Distribution-Participant and Issuer/Selling-Shareholder Restrictions Differ?

Regulation M applies the same trading prohibition to two different sets of parties through two parallel restrictions. Together they cover everyone who has an economic incentive to artificially support the price of the security being placed.

Think of it this way: Both restrictions close the same conduct (artificially propping up the price of the security being placed), but they target different parties. The syndicate gets a meaningful break on actively-traded securities because the manipulation risk is diluted by deep market liquidity. The issuer and selling shareholders never get that break on the security they are distributing, because they have a direct economic incentive that does not go away regardless of liquidity.

Exam Tip: Gotchas

• The distribution-participant restriction covers the SYNDICATE and selling group; the issuer/selling-shareholder restriction covers the ISSUER and selling shareholders. Two parallel Reg M restrictions, two different sets of restricted parties, same restricted period applies to both.
• The actively-traded exception on the security being distributed is a distribution-participant carve-out, NOT an issuer/selling-shareholder carve-out. Even when the syndicate is exempt, the issuer and selling shareholders remain restricted on the security they are distributing. Do not confuse this with the separate, narrow reference-security exception described below.

How Does the Three-Tier Restricted-Period Framework Work?

The restricted period for distribution participants varies with the liquidity of the security being distributed. Three tiers exist, sorted by average daily trading volume (ADTV) and public float thresholds.

Key mechanics of how the tiers work:

• A security qualifies for the actively-traded exception only if BOTH the $1 million ADTV and the $150 million public float thresholds are met. The exception does NOT apply to the issuer or to securities issued by the distribution participant or its affiliates
• Tier 1 status requires hitting BOTH the $100,000 ADTV threshold AND the $25 million public float threshold. Missing either threshold bumps the issue into Tier 2
• The Tier 1 and Tier 2 clocks begin on the later of the stated number of business days before pricing OR the time the person actually becomes a distribution participant, whichever is later. A late-joining underwriter's restricted period can start after pricing-minus-1 or pricing-minus-5, not before it joined the deal
• The restricted period ends when the person completes participation in the distribution. For an underwriter, that means its own allotment (plus any other securities of the same class acquired in the distribution) has been fully distributed AND any stabilization arrangements and trading restrictions tied to the distribution have been terminated, not merely that the trade has settled
• A distribution involving a merger, acquisition, or exchange offer runs on a separate clock: the restricted period begins on the day proxy-solicitation or offering materials are first disseminated to security holders, not on the ADTV/float-based tier schedule, and ends on completion of the distribution

Think of it this way: The framework is a two-step liquidity check. Cross the high threshold ($1 million ADTV plus $150 million float) and the manipulation risk is small enough that the SEC trusts the market to police the price; no restricted period for the syndicate. Fail the high threshold but clear the lower one ($100,000 ADTV plus $25 million float) and you get a 1-day window. Fail either lower threshold and you face the full 5-day window because the security is small enough to move on syndicate trading.

Exam Tip: Gotchas

• The "1 vs 5 business day" tier uses the LOWER thresholds ($100,000 ADTV and $25 million float). Hitting BOTH lower thresholds buys the 1-day window; missing EITHER bumps the issue into the 5-day window. The $1 million and $150 million numbers belong to the SEPARATE, higher actively-traded tier that gets no restricted period at all.
• The actively-traded carve-out is AND, not OR. A security needs both the $1 million ADTV and the $150 million public float to qualify. One out of two is not enough.
• The actively-traded exception does NOT extend to securities issued by the distribution participant or its affiliates. A broker-dealer underwriting its own parent's securities cannot use the exception even if the security otherwise meets the thresholds.
• "Completion of participation" for an underwriter is not just "the trade settled." It also requires that any stabilization arrangements and trading restrictions tied to the distribution have ended. A syndicate that settles its allotment but is still running stabilization has not completed its participation yet.
• A merger, acquisition, or exchange-offer distribution does NOT use the ADTV/float tier schedule. Its restricted period starts when proxy or offering materials are first sent to security holders. Do not force a merger-consideration fact pattern into the 1-day/5-day framework.

Why Is the Issuer/Selling-Shareholder Restriction Tighter?

The issuer and selling shareholders never get the actively-traded carve-out, and certain other distribution-participant exemptions also do not carry over. The reason is the economic-incentive mismatch.

• An underwriter on a deep, liquid security might bid to provide normal market-making liquidity; the manipulation risk is small relative to the existing order book
• An issuer or selling shareholder bidding for its own security during a distribution is closer to pure manipulation, because it is the party that benefits directly from a higher price

Think of it this way: The actively-traded exception assumes the manipulation risk is small enough to ignore. That assumption holds for a broker-dealer touching the order book in a deep market; it does NOT hold for the issuer or for selling shareholders, who have an unambiguous economic reason to push the price up.

Exam Tip: Gotchas

• An issuer bidding for its own stock during a distribution is restricted under Reg M regardless of liquidity. The actively-traded exception does not save them.
• "Affiliated purchasers" of the issuer or selling shareholder are ALSO covered. A creative structure where a related party does the buying does not escape the restriction.

What Are the FINRA Notification Requirements?

FINRA sets the actual notice requirements that let it monitor Regulation M compliance. The manager (or a member acting in a similar capacity) is responsible for these notices; each is identified by the Deal ID the lead manager establishes at the start of the offering.

For a covered security subject to a restricted period:

• Restricted-period determination notice: reports the one-day-or-five-day determination and the basis for it (including the contemplated start date/time, security name and symbol, and the distribution participants and affiliated purchasers), due no later than the business day before the first complete trading session of the restricted period
• Pricing notice: reports the pricing details of the distribution, due no later than the close of business the next business day after pricing
• Cancellation or postponement notice: due immediately upon cancellation or postponement of a distribution for which a restricted-period notice was already filed

For an actively-traded security (no restricted period), the manager still reports the no-restricted-period determination and the pricing details, both due by the close of business the next business day after pricing.

For an OTC Equity Security, a member planning a penalty bid or syndicate covering transaction under the SEC stabilizing-activity rule must separately notify FINRA of its intent before the first penalty bid or covering transaction, then confirm that it occurred within one business day after completion. This notice requirement is specific to OTC Equity Securities; it is not a universal requirement for every distribution.

If no member is acting as manager, each distribution participant or affiliated purchaser must file the notice itself, unless another member has assumed responsibility in writing. An issuer or selling security holder that is a member has the same parallel duty.

Think of it this way: The wire system gives FINRA a real-time view of who is doing what during the distribution, but only specific events actually trigger a mandatory FINRA filing: the restricted-period determination, the pricing, a cancellation or postponement, and (for OTC equity only) the penalty-bid or syndicate-covering activity. Other deal wires (registration effectiveness, closing) coordinate the syndicate internally without being, themselves, a FINRA filing.

Exam Tip: Gotchas

• The restricted-period determination notice is filed BEFORE the restricted period starts (by the business day before the first complete trading session), not after. The pricing notice, by contrast, is filed AFTER pricing (close of business the next business day).
• The OTC-equity penalty-bid/syndicate-covering notice has two parts on two different clocks: intent BEFORE the activity, confirmation within ONE business day AFTER completion. It applies to OTC Equity Securities specifically, not to every distribution.
• There is no separate "stabilizing bid wire" or blanket "Trading Notification" on completion of distribution in the current rule text. Do not invent a filing requirement beyond the restricted-period, pricing, cancellation/postponement, actively-traded, and OTC penalty-bid/syndicate-covering notices FINRA actually requires.
• If there is no manager, responsibility falls to each distribution participant or affiliated purchaser (or each member issuer/selling security holder), unless another member assumes it in writing. Do not assume the lead manager is always personally on the hook.

What Should You Check on Exam Day?

• Confirm which tier applies by checking BOTH ADTV and public float thresholds; missing either one bumps the security to the stricter tier.
• Remember the actively-traded exception on the distributed security is a distribution-participant carve-out only; issuers and selling shareholders keep their restriction on that security regardless of liquidity, subject only to the narrow reference-security exception.
• Verify a security issued by the distribution participant or its affiliate cannot use the actively-traded exception even if it meets the thresholds.
• Check the sequencing and deadlines of the FINRA notices: restricted-period determination before the period starts, pricing the next business day after pricing, cancellation/postponement immediately, and OTC penalty-bid/syndicate-covering intent before and confirmation within one business day after.
• Distinguish the filing mechanics tested in this unit from the substantive stabilization, syndicate-covering, and penalty-bid rules covered in the next unit.
