Welcome to Tender Offer Regulations: the Williams Act framework that governs how a bidder can buy a public company by making a public offer to shareholders, and the disclosure, timing, and equal-treatment rules that police the process.
Exam Weight: Part of 24% / 18 items (Function 3). This is a rule-mechanics unit anchored on the Williams Act and 11 Securities Exchange Act of 1934 rules. Tender-offer questions cluster around timing thresholds, disclosure documents, equal-treatment requirements, and the tender-offer-specific insider trading rule.

What You'll Learn
In this unit, you'll cover:
- The Williams Act Framework: The 1968 amendments to the Securities Exchange Act of 1934 that created the tender-offer disclosure regime; the two regulatory buckets (the third-party and universal tender offer rules); the missing statutory definition of "tender offer"; and the Wellman 8-factor test the courts use to fill that gap
- Schedule TO: The bidder's disclosure vehicle; the four schedule variants (TO, TO-I, TO-T, 13E-3); dissemination methods; and material-change amendments
- The Three Tender-Offer Frameworks: Third-party tender offers under the Williams Act third-party regime, going-private transactions under the going-private rule, and issuer self-tender offers under the issuer tender offer rule
- Target Board Response: Schedule 14D-9, the four permissible positions (recommend, oppose, neutral, or unable to take a position), the 10-business-day clock, and the stop-look-listen notice
- Timing Mechanics: The 20-business-day minimum offering period, extensions triggered by price or quantity changes, withdrawal rights, prompt payment, and the SEC exemptive order narrowing certain negotiated all-cash equity offers to 10 business days
- Equal Treatment: The all-holders rule and the best-price rule, including the compensation carve-out for independent-committee-approved compensation arrangements
- Insider Trading and Trading Restrictions: The tender-offer insider trading prohibition (no fiduciary breach required), the net-long rule for partial tender offers, and the prohibition on bidder purchases outside the offer
- Pro Rata Acceptance and Mini-Tenders: Proration in oversubscribed partial offers, the subsequent offering period option, and why offers for less than 5% of a class escape the third-party tender offer rules entirely
Why This Matters
Function 3 is the M&A, tender offers, and restructuring function (24% of the scored exam). Within Function 3, tender-offer regulation is the highest-density rule-mechanics unit. The exam writes questions that pair a specific timeline event with a procedural requirement, an equal-treatment trigger, or a disclosure document.
The Williams Act has a single organizing principle: disclosure and procedural neutrality. The Act was deliberately written not to favor bidders or targets. Every rule in the framework can be traced back to that purpose: give shareholders enough information and enough time to make an informed decision, and police anyone who tries to gain an unfair edge through nonpublic information or unequal payments.
The exam tests three ideas relentlessly:
- 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 more than 5% after consummation. The universal tender offer rules apply to every tender offer regardless of bidder identity, security type, or registration status.
- What's the timing? Minimum offering period, extensions on material changes, withdrawal rights, and the 10-business-day target response window.
- What documents get filed? Schedule TO (bidder), Schedule 14D-9 (target), Schedule TO-I (issuer self-tender), and Schedule 13E-3 (going-private).
Once you can place a fact pattern against those three axes, you can derive the answer.
Let's start with the Williams Act framework: what the statute did, why courts had to invent a tender-offer definition, and how the Wellman 8-factor test resolved that gap.
