Identify Outside Business Activities — Identify reportable outside business activities and private securities transactions.

Historical Context & Motivation

The regulation of outside business activities (OBAs) and private securities transactions (PSTs) arose from a long history of investor harm caused by registered representatives operating beyond the supervision of their employing broker-dealers. When associated persons engage in financial activities that fall outside their firm's oversight, the risk of fraud, conflicts of interest, and unsuitable recommendations increases dramatically. Regulators recognized early on that a firm cannot fulfill its supervisory obligations if it does not know what its representatives are doing outside of work hours. The rules that govern these activities today are a direct response to real-world scandals in which investors suffered losses precisely because firms were unaware of—or chose to ignore—the outside dealings of their agents.

The central question these rules address is straightforward yet vital: how can a member firm effectively supervise its associated persons—and thereby protect investors—if it does not even know what those persons are doing outside the scope of their employment? FINRA Rules 3270 and 3280 answer that question by imposing prior written notice and, in some cases, prior written approval requirements on associated persons before they engage in outside activities.

Core Principles & Definitions

Understanding the regulatory framework for outside activities requires a firm grasp of several foundational concepts. An associated person is any natural person registered with a FINRA member firm—including registered representatives, principals, and certain other employees. The rules governing OBAs and PSTs apply to all associated persons, not merely those who sell securities directly. The distinction between the two categories—outside business activities under Rule 3270 versus private securities transactions under Rule 3280—is perhaps the most critical conceptual distinction tested on the SIE exam.

Visual Explanation — OBA vs. PST Decision Framework

The visual above captures the essential regulatory logic. Every outside activity by an associated person must first be classified: does it involve a securities transaction, or does it not? The answer determines which rule applies and, consequently, the obligations imposed on both the individual and the firm. Notice that prior written notice is required in every scenario—whether it is a simple OBA like teaching a weekend real estate course or a complex PST like selling interests in a private placement to friends and family. The heightened obligation of prior written approval plus firm supervision kicks in only when the PST involves compensation flowing to the associated person.

How the Rules Work in Practice

FINRA Rule 3270 — Outside Business Activities

Under FINRA Rule 3270, no associated person may be an employee, independent contractor, sole proprietor, officer, director, or partner of another person, or be compensated—or have the reasonable expectation of being compensated—from any other person as a result of any business activity outside the scope of the relationship with his or her member firm, unless the associated person has provided prior written notice to the member firm. The notice must describe the proposed activity in sufficient detail for the firm to assess whether the activity will interfere with the person's responsibilities at the firm, create a conflict of interest, or give the appearance that the firm is involved in the activity when it is not.

• What qualifies: Teaching, coaching, running a side business (e.g., lawn care, consulting), serving on a corporate board for compensation, freelance writing, rental property management for pay.
• What is generally excluded: Passive investments (e.g., owning rental property without active management), unpaid charitable or civic activities (though firms may still require disclosure), and personal investments in one's own brokerage accounts.
• Firm response: The firm must evaluate the notice and may impose conditions, require additional information, or prohibit the activity altogether.

FINRA Rule 3280 — Private Securities Transactions

A private securities transaction is any securities transaction that is outside the regular course or scope of an associated person's employment with a member firm. The colloquial term for this is "selling away" because the associated person is, in effect, selling securities apart from—or away from—the firm's platform. Under Rule 3280, the associated person must provide prior written notice to the firm describing the proposed transaction in detail, the person's proposed role, and whether the person has received or may receive selling compensation. The concept of selling compensation is interpreted broadly and includes commissions, finder's fees, referral fees, equity stakes, or any other economic benefit received in connection with the transaction.

Detailed Breakdown — Classifying Activities

The spectrum above underscores a fundamental regulatory principle: as the activity moves closer to a securities transaction involving compensation, the regulatory obligations intensify. A passive personal investment in a publicly traded stock requires no special disclosure. But the moment an associated person begins actively facilitating securities transactions outside the firm and receiving economic benefit for doing so, the regulatory apparatus demands the firm's full supervisory involvement. Failure to disclose at any level can result in severe disciplinary action, including permanent bars from the industry.

Worked Example — Applying the Rules

Consider the following scenario: Marcus is a registered representative at ABC Securities. A college friend approaches Marcus and asks him to help raise capital for his start-up by selling membership interests in a limited liability company (LLC) to investors. The friend offers Marcus a 3% finder's fee on any capital raised. Marcus is excited about the opportunity and begins soliciting investors among his personal contacts outside of work hours.

Common Scenarios — OBA vs. PST Analysis

Connection to Broader Regulatory Framework

The OBA and PST rules do not exist in isolation—they are interconnected with several other critical regulatory concepts that a finance professional must understand. The duty of supervision under FINRA Rule 3110 obligates member firms to establish and maintain a system of supervision reasonably designed to detect and prevent violations. A firm that fails to establish procedures for tracking and evaluating OBA and PST disclosures may itself face enforcement action for supervisory failures. Additionally, OBAs and PSTs intersect with suitability obligations (Regulation Best Interest for broker-dealers serving retail clients), anti-fraud provisions under Section 10(b) of the Securities Exchange Act and SEC Rule 10b-5, and Form U4 disclosure requirements.

As you advance in your study of securities regulation, you will encounter situations where the OBA and PST rules interact with other obligations. For instance, if a representative fails to disclose a PST and the underlying investment turns out to be fraudulent, the representative may face not only FINRA sanctions under Rule 3280 but also SEC enforcement action under the anti-fraud provisions and potential customer arbitration claims. Firms, too, face respondeat superior liability—they may be held accountable for the actions of their associated persons even when those actions occur outside the firm's formal purview, if the firm's supervisory procedures were deficient.
