Quick Answer
Tender-offer regulation is anchored on three axes: which framework applies (the third-party tender offer rules, the universal tender offer rules, going-private rule, or issuer tender offer rule), which timing thresholds govern (20 business days minimum, 10 business days for price or percentage changes, 10 business days target response, 60 business days withdrawal revival, 3 business days prompt payment), and which document gets filed (Schedule TO for the bidder, Schedule 14D-9 for the target, Schedule TO-I for issuer self-tender, Schedule 13E-3 for going-private). Once a fact pattern is mapped against those three axes, the question's answer follows.
This synthesis section pulls the unit's most-tested facts into reference tables and reinforces the framework you should apply to any tender-offer question.
The Three-Axis Framework
Almost every tender-offer question on the exam can be solved by asking three questions in order.
Axis 1: Which Rules Apply?
| Fact Pattern | Rules |
|---|---|
| Third-party bidder, Exchange Act-registered equity, over 5% after consummation | Third-party tender offer rules (full procedural regime) PLUS the universal tender offer rules |
| Third-party bidder, but under 5% (mini-tender) | Universal tender offer rules only |
| Issuer tender for its own equity | Issuer tender offer rule (PLUS the universal tender offer rules) |
| Going-private transaction (issuer or affiliate, reasonable likelihood of dropping below 300 holders or delisting) | Going-private rule plus the underlying form (TO-I or 14A) |
| Debt securities tender offer | Universal tender offer rules only (third-party tender offer rules apply only to registered equity) |
Axis 2: What Timing Applies?
| Event | Period |
|---|---|
| Minimum offer period | 20 business days (default; narrow 10 business day exemption for negotiated all-cash equity per 2026 SEC order) |
| Extension on price or percentage change | At least 10 business days from notice |
| Extension on other material change | 5 to 10 business days from notice |
| Target response deadline (Schedule 14D-9) | 10 business days from commencement |
| Withdrawal rights | Throughout open offer; revive after 60 business days |
| Prompt payment | Generally 3 business days |
| Subsequent offering period | Minimum 3 business days; no withdrawal rights |
Axis 3: What Document Gets Filed?
| Document | Filer | Trigger |
|---|---|---|
| Schedule TO | Third-party bidder | Third-party tender offer for Exchange Act-registered equity |
| Schedule TO-I | Issuer | Issuer self-tender |
| Schedule 13E-3 | Issuer or affiliate | Going-private transaction (filed in addition to underlying form) |
| Schedule 14D-9 | Target | Target board's position statement (within 10 business days) |
Exam Tip: Gotchas
- The three axes can be answered independently. A question can ask "which regulation applies" without you needing to know the timing or the filing answer. Get good at isolating which axis the question is testing.
Equal-Treatment and Anti-Trading Rules at a Glance
| Rule | What It Requires | Key Detail |
|---|---|---|
| All-holders rule | Offer open to all security holders of the class | Applies per class; common-only tender is OK if preferred is a separate class |
| Best-price rule | Highest consideration paid to any holder flows to every holder | Compensation carve-out: arrangements approved by independent committee are not tender consideration |
| Tender-offer insider trading rule | No trading or tipping on material nonpublic information about a tender offer | NO fiduciary breach required (parity-of-information rule); broader than the general anti-fraud insider trading regime in reach |
| Net-long rule | Cannot tender more shares than net long position in partial tender | Long 10,000 / short 4,000 = net long 6,000 maximum tender |
| Outside-purchase prohibition | Bidder and covered persons cannot buy subject security outside offer during offer window | Covered persons include dealer-managers, contingent-fee advisors, persons acting in concert |
Common Exam Patterns
The exam writes a handful of pattern questions repeatedly. Recognizing the pattern shortcuts the analysis.
Pattern 1: Third-Party vs Universal Scope
The question gives a tender offer fact pattern (debt securities, mini-tender, issuer self-tender, registered equity) and asks which rules apply.
- The third-party tender offer rules apply only to third-party offers for Exchange Act-registered equity when the bidder will own over 5% after consummation
- The universal tender offer rules apply to everything else (and to third-party-rule offers too)
- Anti-fraud, 20-business-day minimum, withdrawal rights, prompt payment all sit in the universal tender offer rules and apply universally
Pattern 2: Target Response Timing
The question describes a target board reacting to a tender offer and asks when the board must respond.
- 10 business days from commencement
- Four permissible positions: recommend acceptance, recommend rejection, neutral, or unable to take a position
- Neutral or unable-to-take-a-position responses require a reason
- Stop-look-listen notice buys time WITHIN the 10-business-day window but does not replace the Schedule 14D-9 obligation
Pattern 3: The Tender-Offer Insider Trading Rule vs the General Anti-Fraud Regime
The question presents an insider trading fact pattern in the tender-offer context (typically the financial-printer fact pattern from Chiarella) and asks which rule reaches the conduct.
- The tender-offer rule does NOT require a fiduciary breach
- The general anti-fraud insider trading regime does
- The 1980 SEC adoption of the tender-offer rule was specifically designed to fill the Chiarella gap
Pattern 4: Going-Private vs Issuer Self-Tender
The question describes an issuer transaction and asks which schedule gets filed.
- Issuer self-tender alone → Schedule TO-I (only)
- Issuer self-tender that takes the company below 300 holders or off-exchange → Schedule TO-I AND Schedule 13E-3
- Cash-out merger that takes the company private → Schedule 14A AND Schedule 13E-3
Pattern 5: Subsequent Period vs Extension
The question describes a bidder seeking to keep an offer open past the initial period.
- Extension: Initial offer still open; triggered by material change in terms; withdrawal rights continue; 10 business days for price or percentage changes; 5 to 10 for other material changes
- Subsequent offering period: Initial offer closed and bidder has accepted shares; minimum 3 business days at same price; NO withdrawal rights; no guaranteed-delivery
Exam Tip: Gotchas
- The five patterns above account for most of the rule-mechanics questions in this unit. When a question feels confusing, ask which pattern it is testing; the answer usually follows.
How the Framework Hangs Together
The Williams Act framework follows a clean cause-and-effect sequence:
- Williams Act (1968) creates the disclosure-and-process regime
- The third-party and universal tender offer rules split the rules by scope (registered equity over 5% vs everything)
- Schedule TO (bidder) and Schedule 14D-9 (target) are the disclosure vehicles
- Timing rules (20 business days, 10-day extension, withdrawal rights, prompt payment) protect shareholder evaluation time
- Equal-treatment rules (all-holders, best-price) prevent side deals
- Tender-offer insider trading rule prevents trading advantages
- Going-private rule and issuer tender offer rule layer in additional disclosure for special cases
- Mini-tender and subsequent offering period are edge cases that test the boundaries of the framework
Memory Aid: WAGS Bids: Williams Act, All-holders rule, Going-private, Schedule TO. The Williams Act creates the regime; the all-holders rule prevents discrimination; the going-private rule covers the issuer-driven freeze-out; Schedule TO is the master disclosure document.
