Reg D vs Reg S: Domestic Exemption, Offshore Safe Harbor, or Both

Sponsors with an international investor list run into a question that does not appear in most real estate syndication checklists: is a Canadian LP’s check a Reg D sale, a Reg S sale, or something that requires both? The answer decides which disclosures appear on the cover page of the PPM, whether the issuer needs a verification process, and how long the securities are locked up before they can be resold.

Regulation D and Regulation S are not substitutes. Regulation D provides exemptions from Securities Act registration when an offering satisfies the selected rule. Regulation S provides nonexclusive safe harbors from Section 5 registration for qualifying offshore offers, sales, and resales. For an international sponsor or a US sponsor with offshore capital, both can appear in the same financing when each tranche independently satisfies its conditions.

This guide walks through what each rule actually does, the three Reg S categories and their implications, how combined Reg D / Reg S offerings work in practice, and what the private placement memorandum looks like when both are running side by side.

Two regulations, two worlds

The Securities Act of 1933 requires every sale of a security to be either registered with the SEC or exempt from registration. Reg D (rules 504, 506(b), 506(c)) provides exemptions for qualifying limited or private offerings. Reg S, by contrast, provides nonexclusive safe harbors for qualifying offshore transactions from the registration requirements in Section 5. It does not switch off the Securities Act’s antifraud provisions or other applicable US, state, or foreign law. The two regimes answer different questions:

• Reg D: “This offer and sale satisfies the conditions of the selected registration exemption.”
• Reg S: “This offer or sale occurs offshore and satisfies the applicable safe-harbor conditions under Rules 903 or 904.”

The key vocabulary word is US person, defined in Rule 902 of Reg S. A US person includes any natural person resident in the United States, any partnership or corporation organized under US law, and a handful of other categories (estates with a US executor, trusts with a US trustee, and so on). For a natural person, residence rather than citizenship is central to the Rule 902 definition, but entities, estates, trusts, accounts, and persons acting for another require their own analysis under the full definition.

Regulation D in one paragraph

Reg D is the domestic private placement regime. For most serious raises, sponsors use Rule 506(b) (private, no general solicitation, up to 35 non-accredited investors) or Rule 506(c) (public solicitation permitted but all investors must be accredited and verified). An issuer relying on Reg D files a notice — Form D — with the SEC within 15 days of first sale, plus any required purchaser-state notices. Securities sold under Rule 506 arerestricted securities, so a resale must be registered or qualify for an exemption. Rule 144’s safe harbor can include a six-month or one-year holding period depending on the issuer’s reporting status and satisfaction of the rule’s other conditions. See 506(b) vs 506(c) for the within-Reg-D decision tree.

Regulation S in one paragraph

Reg S is the offshore safe-harbor framework. The analysis starts with two general conditions: (1) the offer and sale are made in an offshore transaction — generally, the buyer is not in the United States at the time of the sale — and (2) there are no directed selling efforts in the United States. An issuer relying on Rule 903 must also satisfy the conditions for the offering’s Category 1, 2, or 3 classification. Category 1 adds no conditions beyond the general conditions; Categories 2 and 3 add offering restrictions and distribution-compliance periods that vary by issuer, reporting status, and security type.

Reg S’s three categories, briefly

Reg S divides offerings into three categories based on the issuer and the security’s US market presence:

• Category 1: Certain offerings with the lowest risk of flowing back into the United States, including specified foreign-issuer offerings with no substantial US market interest and qualifying overseas-directed offerings. Rule 903 adds no requirements beyond the general offshore-transaction and no-directed-selling-efforts conditions; it does not impose a distribution-compliance period for Category 1.
• Category 2: Offerings not eligible for Category 1 involving equity securities of a reporting foreign issuer, debt securities of a reporting issuer (foreign or domestic), or debt securities of a non-reporting foreign issuer. Offering restrictions apply, together with a 40-day distribution-compliance period.
• Category 3: All offerings not eligible for Categories 1 or 2, including equity securities of reporting US issuers and any securities of non-reporting US issuers. These offerings carry the most extensive conditions. The distribution-compliance period is one year for equity of a non-reporting issuer, six months for equity of a reporting issuer, and 40 days for debt; additional certification, legending, and transfer restrictions depend on the instrument and rule text.

Interests issued by a typical non-reporting US real estate sponsor or private fund often fall in Category 3, but counsel must classify the issuer and instrument rather than assume the result. If the interest is equity of a non-reporting issuer, the applicable distribution-compliance period is generally one year and the Category 3 offering and transfer conditions must be reflected in the subscription and transfer documents.

The combined Reg D / Reg S offering

Sponsors with a mixed investor base — US accredited LPs and offshore LPs from Canada, the UK, the Middle East, or elsewhere — typically structure a Reg D / Reg S dual offering. The single fund or SPV issues one class of securities, but sells them under two different exemptions to two different audiences. The PPM covers both.

Mechanically, this is cleaner than it sounds. The subscription package for US investors includes a Reg D accredited investor questionnaire and standard 506(b) or 506(c) representations. The subscription package for offshore investors includes Reg S representations — specifically, representations that (a) the investor is not a US person, (b) is not acquiring for the account of a US person, (c) understands the distribution compliance period, and (d) will not resell the securities into the US market during the restricted period. Both tracks close into the same fund. The cap table shows one class of securities held by a mix of US accredited and offshore subscribers.

The hardest part of a combined Reg D / Reg S raise is not the legal structure. It is disciplining your marketing so that one audience never contaminates the other.

Many sponsors run the Reg D portion as a 506(c) (with general solicitation) to simplify marketing. When the Reg D portion permits general solicitation, the SEC has taken the position that such solicitation is not automatically fatal to the Reg S offering, so long as the offshore transactions themselves satisfy the offshore transaction requirement and the issuer takes reasonable steps to prevent directed selling efforts into the United States for the Reg S portion. In practice: a general-solicitation website targeting US investors must either exclude offshore buyers or be carefully structured so that offshore subscribers do not arrive through US-targeted marketing.

The directed-selling-efforts trap

The single most common Reg S failure mode is directed selling efforts: any activity undertaken for the purpose of, or that could reasonably be expected to have the effect of, conditioning the US market for the securities. Directed selling efforts include advertisements in US publications with greater-than-nominal US circulation, promotional seminars held in the US, and US-targeted online advertising for the offshore portion.

For a combined Reg D / Reg S offering, the sponsor must maintain a firewall: Reg S investors cannot be solicited through US-targeted channels. The PPM must contain explicit language that the Reg S portion is not being offered to US persons and is not being solicited in the US. Many sponsors add a geo-blocker to their offering website that segregates US vs non-US visitors, or maintain two separate landing pages.

How the PPM drafting changes

A combined Reg D / Reg S PPM looks, structurally, like a standard private placement memorandum — executive summary, sponsor bios, target description, projections, distribution waterfall, risk factors, subscription process. What changes is the layering of disclosures.

Cover page and legend

The cover page cites both exemptions: Rule 506(b) or 506(c) under Reg D and Regulation S for the offshore tranche. A separate legend addresses the Reg S distribution compliance period and resale restrictions.

Investor qualification section

Two tracks appear: (a) US persons must qualify as accredited investors under Reg D and complete a verification process if the offering is 506(c); (b) non-US persons must certify their non-US status, confirm the offshore transaction requirement, and acknowledge the restricted period.

Risk factors

Additional risk factors cover currency exchange risk, cross-border tax treatment (US withholding tax on distributions to non-US investors, treaty benefits, FIRPTA for real estate), the illiquidity of the Reg S restrictive legend, and the possibility that an offshore investor becoming a US person mid-hold would face additional compliance obligations.

Subscription agreement

The subscription agreement either bifurcates into two forms (one for Reg D, one for Reg S) or is a single form with a conditional section that activates the Reg S representations when the subscriber indicates non-US status.

Picking the right structure

For most sponsors, the question is not “Reg D or Reg S” but “Reg D alone, or Reg D and Reg S in parallel”. The default is Reg D alone. Running Reg S in addition is worth it when:

• You have identified non-US investors in your network who want allocation.
• The expected offshore allocation justifies the additional counsel, investor-classification, marketing, transfer, and documentation work required for the Reg S tranche.
• You are comfortable operating the segregated marketing discipline the rule requires.

If none of those apply — if all your investors are US accredited and you have no offshore pipeline — skip Reg S. Adding it to a PPM for a “just in case” offshore subscriber who never arrives adds complexity without benefit.
