Reselling Restricted Securities: Rule 144, Regulation S, and the Exemptions That Move Stock

Document type: Article Practice area: Corporate — Securities Regulation Jurisdiction: United States (federal securities law) Last reviewed: 5 September 2026

The problem created at issuance

Section 5 of the Securities Act, at 15 U.S.C. § 77e, prohibits the sale of a security unless a registration statement is effective or an exemption applies. This applies to every sale, by anyone, not just to the issuer's original offering.

That is the point people miss. A fund that buys preferred stock in a private placement has bought securities that were sold under an exemption available to the issuer — typically the private offering exemption under 15 U.S.C. § 77d(a)(2). When the fund later wants to sell, it needs its own exemption, and the issuer's exemption does nothing for it.

The natural candidate is § 4(a)(1), which exempts "transactions by any person other than an issuer, underwriter, or dealer." Most resales by ordinary investors are covered by it without anyone thinking about it. The difficulty is the word underwriter.

The underwriter problem

Section 2(a)(11) defines an underwriter as any person who has purchased from an issuer with a view to the distribution of a security, or who participates in a distribution, or who offers or sells for an issuer in connection with a distribution. And "issuer," for this purpose, includes any person controlling, controlled by, or under common control with the issuer.

Two consequences follow, and they define the entire field.

First, a person who buys from an issuer intending to resell may be an underwriter, and their resale is then not exempt under § 4(a)(1). Intent at purchase is a fact, and the older cases policed it through the "investment intent" doctrine — buyers gave letters representing that they bought for investment, and courts asked whether the representation was true. Gilligan, Will & Co. v. SEC, 267 F.2d 461 (2d Cir. 1959) held that a purchaser who resold after ten months, having decided to sell when the issuer's fortunes changed, had purchased with a view to distribution — the investment representation notwithstanding.

Second, an affiliate can never simply rely on § 4(a)(1) for an ordinary sale, because a sale by a person who controls the issuer is treated as a sale by the issuer for these purposes. The chief executive selling shares bought in the open market is selling "control securities," and needs an exemption even though the shares themselves were never restricted.

The foundational authority for the underlying exemption analysis is SEC v. Ralston Purina Co., 346 U.S. 119 (1953), which held that the private offering exemption turns on whether the offerees need the protection of registration — whether they can fend for themselves — rather than on their number. That framing runs through the entire resale analysis.

Two kinds of encumbered stock

Practitioners distinguish, and the distinction matters:

Restricted securities are securities acquired directly or indirectly from the issuer, or an affiliate, in a transaction not involving a public offering. They carry a legend. The restriction attaches to the securities.

Control securities are securities held by an affiliate, however acquired — including shares bought on the exchange. The restriction attaches to the holder.

A non-affiliate holding restricted securities has a holding-period problem that eventually resolves itself. An affiliate holding unrestricted securities has a permanent condition that resolves only when they cease to be an affiliate. An affiliate holding restricted securities has both.

Rule 144: the safe harbor

Rule 144, in 17 C.F.R. part 230, provides that a person who satisfies its conditions is deemed not to be engaged in a distribution and therefore not an underwriter, making § 4(a)(1) available. It is a safe harbor, not an exclusive path — but in practice it is the path, because transfer agents and issuers' counsel are unwilling to accept much else.

Condition one: holding period

Applies only to restricted securities.

Issuer type	Holding period
Reporting company, current in its reports	Six months
Non-reporting company	One year

The period runs from the date the securities were acquired from the issuer or an affiliate and fully paid for. A promissory note does not start the clock unless it is full recourse, adequately secured, and the security is not the collateral.

Tacking — adding a prior holder's period to your own — is permitted in defined circumstances, and it is where most of the technical work lies:

Conversion or exchange of the same issuer's securities: the holding period of the surrendered security tacks, so a note converted to stock carries the note's holding period.
Stock dividends, splits, and recapitalizations: tack.
Gifts: the donee tacks the donor's period.
Trusts: tack from the settlor.
Estates: the estate and its beneficiaries tack the deceased's period, and — importantly — if the estate is not an affiliate, Rule 144 conditions largely do not apply.
Pledges: a pledgee tacks the pledgor's period.
Cashless warrant exercise: tacks to the warrant, where the warrant so provided from issuance.
Cash warrant exercise: does not tack; a new holding period begins.
Purchase from an affiliate: the buyer generally starts a new period, because it acquired from an affiliate.
Purchase from a non-affiliate: the buyer tacks the seller's period.

That last pair is the most commonly missed distinction, and it means diligence on a secondary purchase of restricted stock must establish whether the seller was an affiliate.

Condition two: current public information

Applies to affiliates always, and to non-affiliates only during the period between six months and one year for reporting-company securities.

For a reporting issuer, the condition is satisfied if the issuer has filed all required reports (other than current reports on Form 8-K) during the preceding twelve months. For a non-reporting issuer, specified information about the company must be publicly available.

The practical consequence: an affiliate of a delinquent filer cannot sell under Rule 144 at all. A company that misses a periodic report freezes its insiders, which is a real and underappreciated cost of a late filing.

Condition three: volume limitation

Applies to affiliates only.

In any three-month period, an affiliate may sell no more than the greater of:

1% of the outstanding shares of the class; or
The average weekly reported trading volume during the four calendar weeks preceding the notice of sale.

For debt securities, a separate 10% of principal amount test applies.

Aggregation rules matter. Sales by a person and by persons whose sales must be aggregated — spouses and family members sharing a household, entities the person controls, and, in some circumstances, persons acting in concert — are combined.

Condition four: manner of sale

Applies to affiliates only, and to equity securities.

Sales must be made in brokers' transactions, in transactions directly with a market maker, or in riskless principal transactions. The broker may not solicit orders and may receive no more than the usual commission.

What this rules out: an affiliate cannot conduct a marketed offering under Rule 144. Doing so requires registration or another exemption.

Condition five: Form 144

Applies to affiliates only, and only where the sale exceeds 5,000 shares or $50,000 in any three-month period.

A notice on Form 144 must be filed with the Commission concurrently with placing the order. The notice is public and is monitored.

The summary table

Condition	Non-affiliate, restricted securities	Affiliate
Holding period	Six months (reporting) / one year	Same, for restricted securities only
Current public information	Six months to one year only (reporting issuers)	Always
Volume limitation	No	Yes
Manner of sale	No	Yes
Form 144	No	Yes, above thresholds

After one year, a non-affiliate holding restricted securities of any issuer may sell freely, with no conditions at all. That single sentence is the destination of most restricted stock.

The shell company trap

Rule 144 is not available at all for securities of an issuer that is, or at any time previously was, a shell company — unless a demanding set of conditions is satisfied.

Those conditions require that the issuer has ceased to be a shell, is subject to reporting requirements, has filed all required reports for at least twelve months, and has filed "Form 10 information" — the information that would be required to register the class — reflecting its status as a non-shell entity. The securities then become eligible one year after that filing.

Why this matters far beyond obvious shells. The definition captures any issuer with no or nominal operations and either no or nominal assets, or assets consisting solely of cash. Many special purpose acquisition companies fall within it, and so do dormant entities later used for a reverse merger. A holder of securities issued by a company that was once a shell may find their shares ineligible years later, and diligence on Rule 144 eligibility must include the issuer's history, not just its current state.

The alternatives to Rule 144

Section 4(a)(1½)

Not a statutory provision. It is a widely accepted analytical construct: a private resale by a holder to a purchaser who could have bought in the original private placement. The seller is not an underwriter because the resale is itself a private transaction, so no distribution occurs.

The conditions applied in practice mirror those of a private placement:

The purchaser is sophisticated, typically an accredited or institutional investor;
Access to information about the issuer;
No general solicitation;
The purchaser buys for investment and represents so;
The securities remain restricted in the purchaser's hands, with a legend;
The purchaser generally begins a new holding period if the seller was an affiliate.

Ackerberg v. Johnson, 892 F.2d 1328 (8th Cir. 1989) is the standard citation, upholding a private resale to a sophisticated purchaser on this reasoning.

Where it is used: block sales by affiliates who exceed the volume limitation; sales of securities ineligible under Rule 144 because of the shell company provision; and secondary sales of private company stock, where it is the workhorse.

Its limitation: the buyer takes restricted securities and inherits the problem. That is acceptable to a fund with a long horizon and unacceptable to a buyer who wants liquidity.

Regulation S

Regulation S provides that offers and sales occurring outside the United States are not subject to Section 5. It is a territorial approach rather than an exemption.

The general conditions are an offshore transaction and no directed selling efforts in the United States. Additional requirements apply depending on the category, which turns on the issuer's status, the market for the securities, and the risk of flowback.

For resales, the practically important points are:

Sales by affiliates and sales of securities issued by domestic issuers carry additional restrictions and distribution compliance periods;
Securities sold under Regulation S by a domestic issuer are restricted securities for Rule 144 purposes, so Regulation S does not launder the restriction;
Directed selling efforts are broadly defined and include activity that could reasonably be expected to condition the US market;
Certification and legending requirements apply, and transfer agents enforce them.

The recurring misconception is that a US holder can sell restricted stock offshore and take the proceeds free of the restriction. Regulation S provides an exemption for the transaction; it does not convert the securities into freely tradable ones for later US resale.

Registered resale

The issuer registers the holder's shares for resale on a shelf registration statement, and the holder sells into the market as a selling stockholder.

Fast and complete. Registered shares are freely tradable and the legend comes off.
Requires the issuer's cooperation, which is why registration rights agreements exist and are negotiated at the time of investment.
Creates issuer obligations: preparing and maintaining the registration statement, keeping it current, indemnifying the selling stockholders, and suspending sales during blackout periods.
Selling stockholders may be statutory underwriters for liability purposes, with the consequences that follow under the Securities Act's liability provisions.

On liability generally, Pinter v. Dahl, 486 U.S. 622 (1988) defines who is a "seller" liable under Section 12, holding that liability extends beyond title-passers to persons who solicit the purchase, motivated at least in part by a desire to serve their own financial interests or those of the securities owner. That definition is what makes placement agents, and sometimes selling stockholders' representatives, defendants.

Legend removal: where theory meets the transfer agent

None of the analysis matters until the transfer agent removes the restrictive legend, and transfer agents are risk-averse by design.

The standard process:

The holder delivers a representation letter establishing the facts: how and when the securities were acquired, that they have been fully paid for, whether the holder is or has been an affiliate, and the intended manner of sale.
The holder's broker delivers a seller's representation letter confirming the manner of sale.
Issuer's counsel delivers an opinion that the legend may be removed, or that the proposed sale is exempt.
The issuer instructs the transfer agent.
The transfer agent removes the legend or issues unlegended shares.

What goes wrong:

The issuer refuses to instruct. Often because it is delinquent in its reporting, because it disputes the holder's non-affiliate status, or because it simply prefers the shares not to trade. This is a contract and sometimes a tort claim, and registration rights agreements should include an express legend removal covenant.
Counsel will not opine because the facts are unclear — a gap in the chain of title, an uncertain holding period, an unclear affiliate history, or a shell company issue.
The chain of title is broken. Securities transferred several times privately, with incomplete documentation, cannot support an opinion. This is the single most common practical obstacle for older private company stock.
The company was once a shell and nobody checked.

Preventive practice at issuance: keep the subscription documents, the payment records, the certificates or book-entry records, and every transfer document. Ten years later, the opinion depends on them.

Determining affiliate status

Because affiliate status determines which conditions apply, whether a buyer tacks, and whether Rule 144 is available at all for a non-reporting issuer, it deserves its own analysis rather than an assumption.

The definition. An affiliate is a person that directly or indirectly, through one or more intermediaries, controls, is controlled by, or is under common control with the issuer. Control means the possession, direct or indirect, of the power to direct or cause the direction of management and policies, whether through ownership of voting securities, by contract, or otherwise.

Who is clearly an affiliate. Executive officers. Directors. A holder of a majority of the voting power. A controlling stockholder under any reasonable test.

Who is clearly not. An employee below the policy-making level with no board role and a small position. A passive investor with a few percent and no governance rights.

The contested middle, which is where the analysis matters:

A holder with 10–20% and a board seat. Frequently an affiliate. The combination of a significant stake and board representation is the classic profile.
A holder with 20%+ and no board seat. Depends on whether the stake confers practical influence. In a widely held company, a 20% holder often does.
A director designated by a fund. The fund may be an affiliate through the designee, particularly where the designee is a partner of the fund.
A former officer or director. Affiliate status does not end the day service ends. Practice generally treats a person as a former affiliate for a period — commonly three months — before treating them as a non-affiliate, and the conservative approach uses that period.
A family member of an affiliate. Not automatically an affiliate, but sales may be aggregated, and shares received by gift carry the donor's status for a period.
A holder with contractual control rights — board designation, veto rights over major decisions, consent rights over financings — even with a modest stake.

How to analyze it in practice. Do not rely on the holder's self-characterization. Review: the capitalization table; the stockholders agreement and any board designation or consent rights; the board composition and the holder's relationship to each director; the holder's history of influencing decisions; and the issuer's own disclosure, which for a public company will identify its affiliates in various filings.

Document the conclusion. An opinion supporting legend removal for a non-affiliate rests on this determination, and counsel who accepted a representation without analysis has a problem if the determination was wrong.

A practical asymmetry worth noting. Being an affiliate is inconvenient but manageable — the conditions can be satisfied. Being wrongly treated as a non-affiliate is worse: the sale was unregistered and unexempt, the buyer may have a rescission right, and the seller has Section 5 exposure. When the question is genuinely close, treat the holder as an affiliate.

Rule 701 and equity compensation

A large share of restricted securities in private companies arises from equity compensation, and Rule 701 governs their issuance and, importantly, their resale.

The issuance side. Rule 701 exempts offers and sales of securities under written compensatory benefit plans to employees, directors, officers, consultants, and advisers of a non-reporting issuer, subject to volume limits computed against the issuer's assets, outstanding securities, or a dollar cap, and subject to disclosure requirements above a threshold amount.

The resale side, which is the point here. Securities issued under Rule 701 are restricted securities. But Rule 701 provides that, ninety days after the issuer becomes subject to reporting requirements, they may be resold:

By non-affiliates, subject only to the manner-of-sale, current public information, and Form 144 conditions that would otherwise apply — without the holding period;
By affiliates, subject to all of Rule 144's conditions except the holding period.

Why this matters. An employee holding shares from an option exercised two months before the IPO can sell ninety days after the company becomes a reporting company, without waiting out a six-month Rule 144 holding period. The lock-up, not the securities laws, is what actually restricts them — which is the general lesson of this area.

The diligence point. Whether shares were issued under Rule 701 or under a different exemption changes the analysis, and the answer is in the company's records rather than in the certificate. Companies should track the exemption relied on for each issuance; many do not, and reconstructing it years later is difficult.

Worked example one: the affiliate who wants out

The holder. Beatriz Kanellos is Chief Operating Officer and a director of Weatherstone Systems, a reporting company with 46 million shares outstanding and average weekly volume of 310,000 shares. She holds 1.2 million shares: 700,000 acquired in the pre-IPO period as restricted securities, and 500,000 acquired through option exercises after the IPO.

Her status. As an officer and director, she is an affiliate. All 1.2 million shares are control securities. The 700,000 pre-IPO shares are also restricted securities.

The conditions she faces:

Holding period. Satisfied for the pre-IPO shares. The option shares — acquired from the issuer in a transaction not involving a public offering — are restricted unless issued under a registered employee benefit plan on Form S-8, in which case they are not restricted. Check the registration statement; this distinction is routinely assumed and occasionally wrong.
Current public information. Weatherstone must be current in its reports. If it misses a filing, Kanellos is frozen.
Volume. The greater of 1% (460,000 shares) or average weekly volume (310,000). She may sell 460,000 shares per three-month period, aggregated with sales by her spouse and by any entity she controls.
Manner of sale. Brokers' transactions only. No marketed offering.
Form 144. Required, filed concurrently with placing each order.

Her plan. Sell 1.2 million shares over approximately nine months in three tranches, or adopt a Rule 10b5-1 plan so that sales continue during blackout periods.

Two points her counsel must raise.

Section 16(b). Kanellos is a Section 16 insider. Every sale is matchable against any purchase within six months — including option exercises settled with the issuer if the Rule 16b-3 exemption is not properly secured, and including purchases by her spouse. A 10b5-1 plan provides no defense under Section 16(b).

The alternative for the block. If Kanellos wants to sell the entire position at once, Rule 144's volume limit forecloses it. Her options are a registered secondary offering, if the company will do one, or a Section 4(a)(1½) private resale of the block to an institutional buyer, who will take restricted securities and start a new holding period. The private block sale will price at a discount reflecting the illiquidity the buyer accepts.

Worked example two: the fund exiting a private company

The holder. Ostergaard Growth Partners holds Series C preferred stock of Kelvinbridge Analytics, a private company, purchased four years ago. Ostergaard holds 14% and has a board seat.

The questions.

Is Ostergaard an affiliate? A board seat plus 14% is a serious question. Affiliate status turns on control, and a holder with board representation and a significant stake may be a controlling person. Counsel should analyze it rather than assume, because it determines whether the volume and manner-of-sale conditions apply — and whether a buyer tacks Ostergaard's holding period.

Is Rule 144 available? Kelvinbridge is non-reporting. The holding period is one year and is satisfied. But the current public information condition applies to affiliates, and for a non-reporting issuer it requires specified information to be publicly available — which for a private company it is not, absent the company making it so. If Ostergaard is an affiliate, Rule 144 is effectively unavailable.

So the route is Section 4(a)(1½). Ostergaard sells to a secondary fund that is an institutional accredited investor, with no general solicitation, on investment representations, taking restricted securities with a legend.

The complications:

The stockholders agreement almost certainly contains transfer restrictions: a right of first refusal in favor of the company, a co-sale right, and a requirement of board consent. These are contractual and independent of securities law, and they typically take longer to work through than the exemption analysis.
The buyer's holding period. If Ostergaard is an affiliate, the buyer starts fresh. If not, the buyer tacks. This affects price materially, and it is why the affiliate analysis is not academic.
Information rights. The buyer needs financial information to satisfy itself, and the company must agree to provide it.
The company's cooperation is required for the transfer to be recorded, which gives the company leverage it may use.

Worked example three: the founder after an acquisition

The situation. Aurelio Bettencourt founded Pallance Robotics, which is acquired by a public company in a stock-for-stock merger. He receives 900,000 shares of the acquirer, which he holds as restricted securities because they were issued in a transaction not involving a public offering.

His holding period. He may tack the period during which he held his Pallance shares, because the securities were acquired in exchange for securities of the acquired company — provided the exchange satisfies the tacking conditions. His Pallance shares were held for six years, so the acquirer's shares are immediately eligible.

Is he an affiliate of the acquirer? He owns roughly 2% and has no board seat and no officer position. Almost certainly not. A non-affiliate who has held for more than one year sells freely, with no conditions.

The practical steps:

Deliver a representation letter to the acquirer establishing the acquisition date, the tacking basis, and non-affiliate status;
Obtain issuer's counsel's opinion;
Instruct the transfer agent to remove the legend;
Sell.

The obstacle he will encounter: the merger agreement may contain a lock-up, restricting sales for a period regardless of securities law eligibility. Lock-ups are contractual and are enforced. Counsel should read the merger agreement and any separate lock-up before advising on timing — the securities law answer is frequently not the operative constraint.

The consequences of getting it wrong

Section 5 is a strict liability provision, and the remedies are severe enough to warrant conservatism.

Rescission. A purchaser in a transaction that violated Section 5 may rescind — return the securities and recover the purchase price with interest, or recover damages if the securities have been sold. The right exists regardless of whether the seller was negligent, and regardless of whether the purchaser suffered any loss attributable to the violation. A purchaser who bought at $40 and watched the stock fall to $12 has a put option at $40 if the sale was unexempt, and will exercise it.

Who is liable. Under Section 12(a)(1), the "seller" is liable — and Pinter v. Dahl extends that beyond the person who passed title to those who solicited the purchase for their own financial benefit or that of the securities owner. Placement agents, finders, and sometimes company personnel fall within it. Control person liability can reach further.

The limitations period for a Section 12(a)(1) claim is one year from the violation, with an outside limit of three years from the sale — which is short, and which means the exposure is finite. That said, an unexempt sale creates other problems: the issuer's exemption for the original offering can be jeopardized by integration analysis; the company's ability to give a clean opinion on future transfers is compromised; and disclosure of the violation may be required.

Enforcement. The Commission brings Section 5 cases, particularly against those who facilitate unregistered distributions of shell company and microcap securities. SEC v. Cavanagh, 445 F.3d 105 (2d Cir. 2006) is a representative example of the analysis applied to a distribution conducted through nominally exempt transactions, and Geiger v. SEC, 363 F.3d 481 (D.C. Cir. 2004) addresses the underwriter status of a person facilitating a distribution of unregistered shares. The recurring theme is that the substance of the transaction governs, and a chain of individually exempt-looking steps that accomplishes a distribution is a distribution.

The practical implication for counsel. The opinion supporting legend removal is the document that a later enforcement action or rescission claim examines. Give it on documents rather than representations, decline it where the facts are unclear, and record the basis. An opinion that turns out to be wrong because the underlying facts were misrepresented is a different problem from one that was wrong because nobody checked.

Practice notes

For holders.

Determine affiliate status first. It drives everything, and it is a fact question, not a title question.
Establish the holding period with documents, including the tacking chain.
Check the issuer's shell company history, not just its current status.
Confirm the issuer is current in its reporting if you are an affiliate.
Read the contractual restrictions — lock-ups, stockholders agreements, ROFRs, market standoff provisions. They frequently bind longer than the securities laws do.
Negotiate a legend removal covenant in any registration rights or purchase agreement.

For issuers.

Stay current in your reporting. A missed filing freezes every affiliate.
Adopt a legend removal procedure with defined turnaround times and a designated opinion provider. Ad hoc handling generates disputes.
Keep issuance records permanently. The opinion ten years from now depends on them.
Understand your obligations under registration rights agreements before a demand arrives.
Do not use legend removal as leverage in an unrelated dispute. It is a contract claim and, in some circumstances, worse.

For counsel giving opinions.

Establish the chain of title in documents, not in the holder's recollection.
Analyze affiliate status rather than accepting a representation.
Check the shell company history, and say so in the opinion.
Confirm the payment, including whether any note was full recourse.
Confirm the tacking basis against the specific provision relied on.
Confirm the issuer's reporting status as of the sale date, not as of the opinion date, where they differ.

The contractual layer, which usually binds longer

Securities law eligibility is necessary and rarely sufficient. Most holders of restricted stock are also subject to contractual restrictions that outlast the statutory ones, and counsel who advises on Rule 144 without reading the agreements gives incomplete advice.

Lock-up agreements. Signed in connection with an offering, typically restricting sales for 180 days after an initial public offering and shorter periods after a follow-on. They bind officers, directors, and significant holders, and they are enforced. Watch for: early release provisions triggered by price or time; the treatment of gifts and estate transfers; whether the lock-up covers hedging as well as sales; and the underwriters' discretion to release, which is exercised unevenly.

Market standoff provisions. Buried in stock purchase agreements and option agreements, these obligate the holder to sign a lock-up on request. They apply to people who never negotiated a lock-up and often do not know they are bound.

Stockholders and investors' rights agreements. Rights of first refusal in favor of the company or other holders; co-sale and tag-along rights; board or stockholder consent requirements; and transfer restrictions limiting transfers to permitted transferees. In a private company sale, these consume more time than the exemption analysis and can block a transaction entirely.

Registration rights agreements. The mechanism by which a holder can compel a registered resale. Key terms: demand rights and how many; piggyback rights; the issuer's ability to suspend; expenses; indemnification; and — frequently omitted and worth insisting on — an express covenant to remove legends and instruct the transfer agent when a holder becomes eligible.

Company insider trading policies. Apply to employees and often to directors regardless of securities law eligibility, imposing windows and pre-clearance.

Employment and separation agreements. Sometimes contain their own restrictions, forfeiture provisions, or clawbacks tied to sales.

Credit agreements and pledges. Shares pledged to secure a loan cannot be sold without releasing the pledge, and margin arrangements have their own mechanics.

The advice that follows. When a client asks "when can I sell," the answer requires two analyses: the securities law eligibility date, and the contractual release date. The later of the two is the answer, and in the great majority of cases it is the contractual one.

Quick reference

The statutory question. Every sale needs registration or an exemption. The exemption most resales rely on is for transactions by a person other than an issuer, underwriter, or dealer — and the difficulty is that a person who bought with a view to distribution, or who sells for a person controlling the issuer, is an underwriter.

Two kinds of encumbered stock. Restricted securities — acquired from the issuer or an affiliate in a non-public transaction; the restriction attaches to the shares. Control securities — held by an affiliate however acquired; the restriction attaches to the holder.

Rule 144, at a glance.

	Non-affiliate, restricted	Affiliate
Holding period	6 months (reporting) / 1 year	Same, restricted securities only
Current public information	6–12 months only	Always
Volume limit	No	Greater of 1% or average weekly volume
Manner of sale	No	Brokers' transactions only
Form 144	No	Yes, above thresholds

After one year, a non-affiliate sells freely with no conditions. That is where most restricted stock ends up.

The traps. The shell company provision, which suspends Rule 144 for any issuer that ever was a shell until a year after Form 10 information is filed. Cash warrant exercises, which do not tack. Purchases from affiliates, which start a new holding period. Delinquent issuer reporting, which freezes every affiliate. And a broken chain of title, which no opinion can cure.

The alternatives. Section 4(a)(1½) private resale, where the buyer takes restricted securities. Regulation S offshore, which exempts the transaction but does not clean the securities. Registered resale on a shelf, which is complete but requires the issuer's cooperation.

The practical bottleneck. Legend removal, which requires a representation letter, a broker's letter, and an opinion — and which fails on incomplete records more often than on legal analysis.

The advice that is right most of the time. Determine affiliate status carefully and, when it is close, assume affiliate. Establish the holding period from documents. Check the issuer's shell history. And read the lock-up, because it usually binds longer than the rule does.
