Question 1

What does it mean to treat an IPO as a securities-offering "transaction"?

Accepted Answer

Viewed structurally, an IPO is a registered transaction in which securities are offered and sold to the public. Section 5 of the Securities Act of 1933 makes it generally unlawful to use interstate commerce or the mails to offer or sell a security to the public except in compliance with the Act's registration requirements — a security generally may not be sold unless a registration statement is in effect for it. Section 6(a) of the Act ties the transaction to a defined quantity of securities: a registration statement 'shall be deemed effective only as to the securities specified therein as proposed to be offered.' Because the registration reaches only the securities 'specified therein as proposed to be offered,' the transaction has a fixed perimeter — a stated title and amount of securities that the issuer, and any selling holders, propose to sell. Everything else in the offering is built around that perimeter: which securities are being sold, by whom, through what distribution, and on what economic terms. This page describes that structure; the ordered stages the transaction moves through are addressed on the IPO Lifecycle page, and the specific registration form most companies use is addressed on the S-1 Filing page.

Question 2

What are the two regulated acts in the transaction — an "offer" and a "sale"?

Accepted Answer

Section 2(a)(3) of the Securities Act defines the two acts that make up the transaction. A 'sale' or 'sell' includes 'every contract of sale or disposition of a security or interest in a security, for value.' An 'offer to sell,' 'offer for sale,' or 'offer' includes 'every attempt or offer to dispose of, or solicitation of an offer to buy, a security or interest in a security, for value.' Both turn on the element 'for value' — the consideration passing in the transaction. The statute treats offering and selling as distinct, separately regulated legs of the same transaction, which is why Section 5 restricts offers as well as sales. Section 2(a)(3) also contains an anti-evasion rule tied to consideration: 'Any security given or delivered with, or as a bonus on account of, any purchase of securities or any other thing, shall be conclusively presumed to constitute a part of the subject of such purchase and to have been offered and sold for value.' The way pre-effective communications can themselves be 'offers' before any sale occurs is addressed on the Waiting-Period Communications page.

Question 3

Are the issuer's negotiations with its underwriters "offers" in the transaction?

Accepted Answer

No. Section 2(a)(3) of the Securities Act carves the deal-structuring negotiations out of the definitions of 'offer' and 'sale.' The defined terms, and the term 'offer to buy' as used in Section 5(c), 'shall not include preliminary negotiations or agreements between an issuer (or any person directly or indirectly controlling or controlled by an issuer, or under direct or indirect common control with an issuer) and any underwriter or among underwriters who are or are to be in privity of contract with an issuer.' This carve-out is what allows the issuer and its underwriting syndicate to negotiate and agree the terms of the transaction — how many securities, on what basis, at what discount — without those preliminary negotiations counting as 'offers' subject to Section 5's prohibitions. The offers and sales that Section 5 reaches are those directed at the investing public, not the issuer-to-underwriter or underwriter-to-underwriter dealings that assemble the offering. The roles the various parties play in that syndicate are addressed on the IPO Ecosystem page.

Question 4

What are "primary" shares in the transaction?

Accepted Answer

Primary shares are securities the company itself issues and sells in the offering. The seller of primary shares is the issuer — under Section 2(a)(4) of the Securities Act, 'every person who issues or proposes to issue any security.' On the prospectus cover, the economic result of a primary sale is shown under Regulation S-K Item 501(b)(3) as 'the net proceeds you receive' — that is, the net proceeds to the registrant. Because primary shares are newly issued, selling them raises new capital for the company, and the proceeds flow to the issuer rather than to any existing holder. The issuer is also the party that files the registration statement and signs it — under Section 6(a), the registration statement must be signed by each issuer, its principal executive officer(s), its principal financial officer, its comptroller or principal accounting officer, and a majority of its board. What the company may do with those net proceeds is addressed on the Use of Proceeds page, and the broader mechanics of raising capital are addressed on the IPO Capital Raise page.

Question 5

What are "secondary" shares, and who sells them?

Accepted Answer

Secondary shares are outstanding securities sold by existing holders rather than newly issued by the company. Regulation S-K Item 507 addresses this side of the transaction: it applies 'if any of the securities to be registered are to be offered for the account of security holders.' Those holders are the selling security holders, and the proceeds from their shares go to them, not to the issuer. A single IPO can register primary shares, secondary shares, or a combination of both. When existing holders sell into a registered offering, their shares are registered alongside the issuer's, but the cash from those sales is theirs. Because Item 504's Use of Proceeds disclosure covers only net proceeds to the registrant, a purely secondary offering produces no registrant proceeds for that item to describe — the Use of Proceeds page addresses that point. Existing holders often agree not to sell for a set period after the IPO; those restrictions are addressed on the Lock-Up Agreements page.

Question 6

What must the registration statement disclose about selling security holders?

Accepted Answer

For each selling security holder in a secondary offering, Regulation S-K Item 507 requires the registration statement to name the holder; indicate the nature of any position, office, or other material relationship the holder has had within the past three years with the registrant or any of its predecessors or affiliates; and state the amount of the class owned before the offering, the amount to be offered for that holder's account, and the amount — and, if one percent or more, the percentage — of the class to be owned after completion of the offering. Item 507 is the disclosure hook that makes the secondary side of the transaction transparent: it identifies exactly who is selling, how much they hold going in, how much they are putting into the offering, and where they stand once it closes. This lets a reader distinguish the company's own sale of new shares from insiders' or early investors' sale of existing shares within the same prospectus. The rule text describes what must be disclosed and is a U.S. Government work available at the linked eCFR section.

Question 7

How does the prospectus cover show the economics of the transaction?

Accepted Answer

The outside front cover of the prospectus separates the money in the transaction. Regulation S-K Item 501(b)(2) requires the title and amount of securities offered, and directs the registrant to 'separately state the amount of securities offered by selling security holders, if any.' Item 501(b)(3) requires, for a cash offering, 'the price to the public of the securities, the underwriter's discounts and commissions, the net proceeds you receive, and any selling shareholder's net proceeds,' shown both per share (or unit) and for the total offering. Read together, these cover-page requirements let a reader see, at a glance, how big the transaction is, how much of it is primary versus secondary, and how the gross price to the public splits into underwriting compensation, net proceeds to the issuer, and net proceeds to any selling holders. The registrant may present this in a table, term-sheet, or other clear format under Item 501(b)(3). How the price to the public itself is arrived at is addressed on the Bookbuilding and Pricing page; the underwriting discounts and fees are addressed on the IPO Fees page.

Question 8

What is the "plan of distribution," structurally?

Accepted Answer

The plan of distribution is the disclosure that describes how the securities move from the sellers to the public. Under Regulation S-K Item 508(a), if the securities are offered through underwriters, the registrant must name the principal underwriters, state the respective amounts underwritten, identify any underwriter with a material relationship to the registrant, and 'state briefly the nature of the obligation of the underwriter(s) to take the securities.' In a typical firm-commitment IPO, this maps a three-step path: the securities move from the issuer (and any selling holders) to the underwriting syndicate, and from the syndicate to the investing public. Item 508 also governs related disclosures, including the underwriter's-compensation table under Item 508(e), which 'must show the separate amounts to be paid by the company and the selling shareholders' — again separating the primary and secondary sides. The rule is a U.S. Government work available at the linked eCFR section; the participants' respective roles are addressed on the IPO Ecosystem page.

Question 9

What is the difference between a firm-commitment and a best-efforts structure?

Accepted Answer

The difference is the nature of the underwriters' obligation to take the securities. Under the Instruction to Regulation S-K Item 508(a), the disclosure must state whether the underwriters 'are or will be committed to take and to pay for all of the securities if any are taken' — a firm commitment — 'or whether it is merely an agency or the type of best efforts arrangement under which the underwriters are required to take and to pay for only such securities as they may sell to the public.' In a firm-commitment offering, the underwriters bear the risk that they may not resell all the securities; in an agency or best-efforts offering, they undertake only to try. The prospectus cover reflects this too: Regulation S-K Item 501(b)(8) requires the name(s) of the lead or managing underwriter(s) and identification of the nature of the underwriting arrangements, and, if the offering is not made on a firm-commitment basis, a brief description of the arrangements (for example, a best-efforts or minimum/maximum offering). Most traditional IPOs use a firm-commitment structure; the pricing and allocation mechanics are addressed on the Bookbuilding and Pricing page.

Question 10

In a firm-commitment IPO, how does the statute frame the underwriters as buyers who resell?

Accepted Answer

Section 2(a)(11) of the Securities Act defines an 'underwriter' as any person who 'has purchased from an issuer with a view to, or offers or sells for an issuer in connection with, the distribution of any security, or participates or has a direct or indirect participation in any such undertaking.' In a firm-commitment offering, the underwriters purchase the securities from the issuer (and any selling holders) and resell them to the public — the resale being the 'distribution.' This is why the transaction has a wholesale leg and a retail leg: the underwriters acquire the securities to distribute them, then offer and sell them onward to investors. For purposes of the definition, 'issuer' is expanded to include any person controlling, controlled by, or under common control with the issuer, and the term excludes a person whose interest is limited to a customary distributor's or seller's commission. Because selling security holders who dispose of their shares as part of a distribution can themselves fall within this definition, the registration covers their sales as well; the settlement timing of the firm-commitment purchase is addressed on the Bookbuilding and Pricing page.

Question 11

Are both the primary and the secondary sales registered in the transaction?

Accepted Answer

Yes. Section 5 of the Securities Act reaches every offer and every sale made to the public through interstate commerce or the mails, unless a registration statement is in effect. A registration statement can cover securities the issuer proposes to sell (primary) and securities 'offered for the account of security holders' under Regulation S-K Item 507 (secondary) in the same document, so both sides of the transaction are registered together. Section 5(a) makes it unlawful, absent an effective registration statement, to use interstate commerce or the mails to sell a security or to deliver it after sale; Section 5(c) bars offers before a registration statement is even filed. Because Section 6(a) provides that a registration statement is effective 'only as to the securities specified therein as proposed to be offered,' the registered perimeter must expressly include both the issuer's primary shares and any selling holders' secondary shares for each to be sold lawfully in the offering. The point at which the registration statement becomes effective, and what may happen before then, is addressed on the S-1 Filing page.

Question 12

How is the size of the transaction measured for the SEC's registration fee?

Accepted Answer

The registration fee is computed on the size of the transaction. Section 6(b)(1) of the Securities Act requires that, at the time of filing, the applicant pay a fee at a rate applied to 'the maximum aggregate price at which such securities are proposed to be offered.' The base statutory rate is stated as $92 per $1,000,000 of that maximum aggregate offering price, and Section 6(b)(2) directs the SEC to adjust the rate by order for each fiscal year beginning with fiscal year 2003. This ties the government-facing cost of the transaction directly to its registered size: the larger the maximum aggregate offering price, the larger the fee. Under Section 6(b)(3), the per-$1,000,000 rate is applied pro rata to amounts and balances of less than $1,000,000. Because Section 6(b)(2) requires an annual adjustment, the effective fee rate changes from year to year and is set by SEC order rather than fixed in the statute; the current-year rate and the fee-computation rules are addressed on the IPO Fees page.
