Types of Underwriting Commitments

Now that you understand who signs the syndicate documents, the next question is what they actually agreed to do. The commitment type chosen at signing controls the entire risk and economics of the deal.

How Do the Seven Commitment Types Compare?

Think of it this way: Two questions sort every commitment type. First, is the underwriter a principal (buying for resale) or an agent (distributing for a fee)? Second, who keeps the risk if shares do not sell? Firm commitment = principal, underwriter holds the risk. Best efforts = agent, issuer holds the risk. AON and mini-max are best efforts plus a contingency that wipes the deal if the minimum is not hit.

What Is a Firm Commitment Underwriting?

In a firm commitment offering, the underwriter signs the underwriting agreement at pricing and becomes contractually obligated to purchase the entire offering from the issuer at the agreed price. The underwriter then resells those shares to investors at the public offering price (POP).

• Used for the largest and most stable issuers: investment-grade equity and debt initial public offerings (IPOs) and follow-on offerings
• Underwriting fees are higher than best-efforts compensation because of the inventory risk premium
• Settlement of the issuer-to-syndicate purchase happens at the closing date (a few business days after pricing under the standard settlement cycle); the underwriter has typically pre-sold the shares to investors during marketing and only carries true unsold inventory if the book did not clear

Think of it this way: A firm commitment is the underwriter telling the issuer "we will write the check for the full raise; getting it back out to investors is our problem." The risk to the underwriter is not warehousing securities for weeks but failing to place the allocation between pricing and the closing date.

Exam Tip: Gotchas

• Firm commitment does NOT mean the underwriter warehouses the securities pre-offering. The issuer-to-syndicate purchase settles at the closing date. By the time the underwriter actually pays the issuer, the shares are usually already pre-sold to investors at the POP. The risk window is between pricing and closing, not before pricing.
• The underwriter's principal-versus-agent status flips here. In firm commitment the underwriter is a principal (buyer and reseller). In best efforts the underwriter is an agent (distribution-only). The exam often tests this distinction by asking who has title to the shares between pricing and resale.

What Is a Best Efforts Underwriting?

In a best efforts offering, the underwriter agrees only to use its reasonable efforts to distribute the issue. The underwriter never takes principal title to the shares; it acts as a distribution agent.

• Used for smaller, less-established issuers where firm-commitment pricing risk is too high for the underwriter to accept
• Compensation is lower than firm commitment (no inventory-risk premium)
• Unsold portion simply does not raise capital for the issuer; the underwriter is not on the hook to make it up

Exam Tip: Gotchas

• The issuer bears the risk under plain best efforts. If the underwriter cannot place the full deal, the issuer raises less capital but the underwriter is not liable for the shortfall.
• Plain best efforts (no contingency) still falls under the investor-payment rule, just through its simpler "promptly transmit" path, not the escrow/segregation path. The escrow path covered in the contingency section flows from the contingency promise (AON or mini-max), not from the agent structure itself.

How Do All-or-None (AON) and Mini-Max Offerings Work?

AON and mini-max are best-efforts variants with a contingency: the deal closes only if a specified minimum dollar amount or share count is placed by a stated deadline.

• All-or-none (AON): 100% of the offering must sell by the deadline. If even one share short, the offering is cancelled and all investor funds are returned
• Mini-max: a minimum threshold (e.g., $5 million) must clear. Once the minimum is met the deal closes and can scale toward a maximum (e.g., $10 million)
• Both trigger the SEC contingency offering rules (covered in the next section): the prohibited-representations rule polices the contingency promise, and the investor-payment rule's escrow/segregation path controls how investor funds must be held while the contingency is open

Exam Tip: Gotchas

• AON and mini-max trigger contingency rules; plain best efforts does NOT. The contingency representation is the switch. An underwriter using the AON or mini-max label cannot quietly walk away from the refund obligation; the rules attach automatically.
• AON is binary (all or nothing). Mini-max has a sliding success range above the minimum. A common trap answer mixes the two by giving the AON deal a partial-success scenario; AON only has "fully placed" or "cancelled."

What Is a Standby Commitment?

A standby commitment is a backstop on a rights offering. In a rights offering, the issuer gives existing shareholders subscription rights to buy their pro-rata share of new stock at a discount to market. Not every shareholder exercises the rights, so the issuer faces under-subscription risk unless somebody guarantees the leftover.

• The standby underwriter agrees to purchase any rights NOT exercised by shareholders
• Compensation is typically a standby fee plus warrants or preferential pricing on the unsubscribed shares the underwriter ends up forced to take
• The standby removes the issuer's risk of an under-subscribed rights offering; that risk is now sitting on the underwriter

Exam Tip: Gotchas

• A standby commitment is NOT a best-efforts structure. The standby underwriter has a firm obligation to take any unsubscribed shares; it is functionally a firm commitment on the leftover. Best-efforts framings on a standby question are almost always wrong.
• A standby goes with a rights offering, not a general public offering. If a question describes a standby commitment without mentioning rights or existing shareholders, double-check the facts; standby exists to backstop rights, not to anchor an IPO.

How Do Competitive Bid and Negotiated Selection Differ?

The final dimension is how the issuer chose the underwriter in the first place: by auction or by negotiation. Competitive bid and negotiated describe that selection process, not the commitment type itself.

Both are typically paired with a firm-commitment purchase obligation once a winning bid or negotiated agreement is in place. But the actual purchase obligation in the underwriting agreement, not the selection method alone, controls who bears the risk of unsold securities.

• Competitive bid: the issuer (often a municipality, agency, or investment-grade corporate debt issuer) publishes a notice of sale; multiple underwriting syndicates submit sealed bids under stated criteria; the lowest interest cost or highest price wins. Common in municipal general obligation (GO) bonds and agency debt
• Negotiated: the issuer pre-selects the underwriter and negotiates price, structure, covenants, and fees directly. Standard for IPOs, follow-on equity, revenue bonds, and complex or lower-credit-quality offerings where book-building and marketing are critical

Exam Tip: Gotchas

• Competitive bid is the auction; negotiated is the conversation. A competitive-bid award goes to the bid that lowers the issuer's cost of capital the most. A negotiated deal is set through book-building, marketing, and price talks between the issuer and a single pre-selected syndicate.
• IPOs are essentially always negotiated. Book-building, road shows, and price discovery for first-time public-equity issuers do not fit an auction format. Competitive-bid framings on an IPO question are almost always wrong.
• Do not infer the commitment type solely from the selection method. Competitive bid and negotiated answer "how was the underwriter chosen," not "who bears the risk of unsold shares." Read the actual purchase obligation in the fact pattern before assigning firm-commitment risk.

What Should You Check on Exam Day?

• Identify whether the underwriter acts as principal (firm commitment, standby) or agent (best efforts, AON, mini-max) before assigning risk of unsold shares; for competitive bid or negotiated, read the actual purchase obligation.
• Do not assume firm commitment means pre-offering warehousing; the risk window is between pricing and closing, not before pricing.
• Distinguish AON's binary outcome (fully placed or cancelled) from mini-max's sliding range above the minimum.
• Confirm a standby commitment is paired with a rights offering, not treated as a general-purpose best-efforts structure.
• Check whether the fact pattern names a municipal general obligation bond or agency debt (likely competitive bid) versus an IPO or complex deal (negotiated).
