Underwriting Syndicate Activities

The whole unit on one sheet: the syndicate documents, the commitment types, the contingency rules, lock-ups, Regulation M filings, and the price-and-concession disclosure the exam loves.

Which One-Liners Win Points?

• The Agreement Among Underwriters (AAU) is signed by every syndicate member and sets liability as several, NOT joint: each underwriter is liable only for its own share.
• The Selected Dealers' Agreement is signed by selling-group dealers, who bear NO inventory risk and earn only the concession (no underwriting fee, no management fee).
• The lead manager allocates the issue, sets price, signs the underwriting agreement, and runs stabilization; lead status adds fees and duties but does not exempt it from underwriting liability.
• Firm commitment: underwriter is a principal (buys the entire issue, resells at the public offering price); the underwriter bears unsold-share risk. Best efforts: underwriter is an agent (never takes title); the issuer bears the risk.
• All-or-none (AON) and mini-max are contingency variants of best efforts; standby is a firm commitment on unsubscribed shares in a rights offering. Competitive bid (auction, common in municipal general-obligation bonds) and negotiated (book-building; IPOs are essentially always negotiated) describe SELECTION method, separate from commitment type.
• Prohibited-representations rule: triggered specifically by an AON, part-or-none, or mini-max representation (prompt refund if not sold); a genuine firm commitment is outside it entirely. Investor-payment rule: triggered more broadly by ANY non-firm-commitment distribution; a contingency only decides whether the stricter escrow path applies instead.
• Issuer lock-ups bar new share issuance; shareholder lock-ups bar officers, directors, founders, and pre-IPO holders from selling existing shares. Both are private contracts, NOT SEC mandates; the SEC only requires terms be disclosed in the prospectus. Typical IPO shareholder lock-up is 180 days, but the agreement sets the actual term.
• The underwriter typically holds the right to grant an early lock-up waiver, not the issuer or the holders; it is an agreement term, not a fixed rule.
• Regulation M restricts distribution participants and, in parallel, issuers and selling shareholders; only distribution participants get the actively-traded exception. The restricted period ends when a participant completes participation (fully distributed AND stabilization/trading restrictions terminated, not just settled).
• The FINRA selling-agreement disclosure rule requires every AAU and Selected Dealers' Agreement to state the public offering price (POP) (or a formula) and the concession terms, in writing, between dealers (NOT to the public investor).

Which Numbers Matter Most?

Which Gotchas Trip Students Up?

• Selling group members are NOT syndicate members; unsold shares revert to the lead manager, and members sign the Selected Dealers' Agreement, not the AAU.
• AAU liability is several, NOT joint. One underwriter's failure does not put the others on the hook; "stepping up" is a contractual term, not a rule of law.
• Firm commitment does NOT mean the underwriter warehouses securities pre-offering. The risk window is between pricing and closing; shares are usually pre-sold by then.
• A standby commitment is NOT best efforts. The standby underwriter has a firm obligation to take unsubscribed shares, backstopping a rights offering, not a general public offering.
• AON is binary (fully placed or cancelled). Mini-max has a sliding success range above the minimum; a partial-success AON scenario is a trap answer.
• Plain best efforts (no contingency) uses the simpler "promptly transmit" path, not escrow/segregation. The contingency label, not the agent structure, triggers the escrow mechanic.
• Apply the SEC staff interpretation the exam follows: "promptly" means noon of the next business day, and the escrow bank must be UNAFFILIATED with the issuer and broker-dealer.
• 180 days is convention, not a regulatory minimum. The lock-up cliff is the EXPIRATION date; a waiver is a discretionary early release, not the cliff, and generally requires public notice.
• The actively-traded exception is a distribution-participant carve-out only, needing BOTH thresholds (AND, not OR). Issuers and selling shareholders stay restricted regardless of liquidity.
• The selling-agreement disclosure is INSIDE the dealer agreements, not to the public investor; a dealer cannot rely on the prospectus to learn its own concession.

One-Breath Recap

A syndicate runs on the Agreement Among Underwriters (several-not-joint liability) and the Selected Dealers' Agreement, signed by dealers who bear no inventory risk and earn only the concession. Commitment type decides who eats unsold shares: firm commitment (principal, underwriter's risk), best efforts (agent, issuer's risk), with all-or-none and mini-max as contingency variants triggering the prohibited-representations and escrow rules, and standby as a firm commitment on a rights offering. Lock-ups are private, typically 180-day contracts, not SEC mandates, with the underwriter usually holding the waiver right. Regulation M restricts distribution participants (actively-traded exception) and, in parallel, issuers and shareholders (no exception), across a no-day, 1-day, or 5-day period; the selling-agreement disclosure rule lives inside the dealer agreements, not the prospectus.
