FINRA Rule 2111: suitability for small broker-dealers
15 min read

Three obligations in one rule
Rule 2111 binds FINRA member firms and their associated persons each time they recommend a transaction or an investment strategy involving a security. The rule's core is the sentence quoted above: a reasonable basis to believe the recommendation is suitable, built on reasonable diligence into the customer's investment profile. Its supplementary material splits that duty in three: “Rule 2111 is composed of three main obligations: reasonable-basis suitability, customer-specific suitability, and quantitative suitability.”
2111.05(a)01
Reasonable-basis suitability
Is this security or strategy suitable for at least some investors?
The product itself: its risks and rewards, understood through reasonable diligence.
2111.05(b)02
Customer-specific suitability
Is it suitable for this customer?
The customer's investment profile, as delineated in Rule 2111(a).
2111.05(c)03
Quantitative suitability
Taken together, is the series of recommended transactions excessive?
The profile again, read across the account's activity rather than one trade.
The first obligation is about the product, not the customer. A recommendation has to be suitable “for at least some investors”, and the rule ties the diligence it takes to the product: what counts as reasonable diligence varies with “the complexity of and risks associated with the security or investment strategy” and with the firm's familiarity with it.
For a firm of a few representatives this is the shelf decision. Before a new product is recommended to anyone, someone at the firm should be able to show what they read about it and why they understood its risks. That note answers the reasonable-basis question for every customer who later buys it. Nor can a customer agreement move the duty: “A member or associated person cannot disclaim any responsibilities under the suitability rule.”
Rule 2111 or Regulation Best Interest
A broker-dealer now works under two recommendation standards, and the first question for any recommendation is which one governs it. FINRA answered in the rule itself. The line was added by the amendment FINRA lists as SR-FINRA-2020-007, effective June 30, 2020.
SEA Rule 15l-1 is Regulation Best Interest. A broker-dealer recommending a securities transaction or strategy, account recommendations included, to a retail customer “shall act in the best interest of the retail customer at the time the recommendation is made, without placing the financial or other interest of the broker, dealer, or natural person who is an associated person of a broker or dealer making the recommendation ahead of the interest of the retail customer.” The rule says that obligation is satisfied through four component obligations.
Regulation Best Interest, four component obligations
- 01Disclosure obligation15l-1(a)(2)(i)
- 02Care obligation15l-1(a)(2)(ii)
- 03Conflict of interest obligation15l-1(a)(2)(iii)
- 04Compliance obligation15l-1(a)(2)(iv)
Which standard governs a recommendation
| The recommendation | The standard | Rule |
|---|---|---|
| To a retail customer, subject to Regulation Best Interest | Reg BI's best-interest obligation. Rule 2111 does not apply. | 15l-1(a)(1); 2111.08 |
| Outside Regulation Best Interest | Rule 2111 and its three obligations, by our reading of 2111.08. | 2111; 2111.08 |
| Outside Reg BI, to an institutional account meeting 2111(b)'s two conditions | Rule 2111, with the customer-specific obligation met through 2111(b). | 2111(b); 4512(c) |
FINRA Rule 2111.08; 17 CFR 240.15l-1(a)(1)
Which customers Regulation Best Interest covers is a question for its own text, which this guide does not restate: read the rule text at 17 CFR 240.15l-1 and settle with your compliance counsel which of your customers it covers. Write the answer into your procedures, because it decides which standard a principal checks each recommendation against.
Regulation Best Interest brings its own record. For each retail customer who gets a recommendation, the firm keeps “a record of all information collected from and provided to the retail customer pursuant to § 240.15l-1, as well as the identity of each natural person who is an associated person, if any, responsible for the account.” It is kept until at least six years after the earlier of the account closing or the information being collected, provided, replaced or updated (17 CFR 240.17a-3(a)(35)(i); 240.17a-4(e)(5)). Form CRS runs on its own clock and its own defined term, the retail investor: a broker-dealer delivers it before or at the earliest of a recommendation, placing an order, or opening a brokerage account (17 CFR 240.17a-14(c)(1)). Our Form CRS builder drafts the document. How suitability sits among a small member firm's other duties is mapped in FINRA compliance for small broker-dealers.
The customer investment profile

The customer-specific obligation is only as good as what the firm knows about the customer. Rule 2111 names what that is: “A customer's investment profile includes, but is not limited to, the customer's age, other investments, financial situation and needs, tax status, investment objectives, investment experience, investment time horizon, liquidity needs, risk tolerance, and any other information the customer may disclose” to the firm in connection with the recommendation.
A new-account form built for the SEC's account record rule already collects part of this, because 17a-3(a)(17) asks for some of the same facts on natural-person accounts. The overlap is partial, and the gap is where a profile goes thin.
Nine named factors, and which ones the SEC account record also asks for
| Rule 2111(a) factor | Also on the 17a-3(a)(17) account record? |
|---|---|
| Age | Yes: date of birth |
| Other investments | Not named |
| Financial situation and needs | In part: annual income, net worth (excluding primary residence) |
| Tax status | Not named |
| Investment objectives | Yes: the account's investment objectives |
| Investment experience | Not named |
| Investment time horizon | Not named |
| Liquidity needs | Not named |
| Risk tolerance | Not named |
FINRA Rule 2111(a); 17 CFR 240.17a-3(a)(17)(i)(A)
Six of the nine have no line on the SEC record: other investments, tax status, investment experience, time horizon, liquidity needs and risk tolerance. A seventh, financial situation and needs, is covered only in part by income and net worth. A form built only to satisfy 17a-3 leaves those to chance, so add the missing lines to the new-account form itself rather than to a separate questionnaire nobody updates.
Two phrases in that sentence set the paperwork. “Obtain and analyze” means the factor is used, not only collected. “Documented with specificity” means a blank needs a reason written for this customer; a form-wide “not applicable” box is not one. The rule also allows that “the level of importance of each factor may vary depending on the facts and circumstances of the particular case”.
What counts as a recommended strategy
The rule covers a “recommended transaction or investment strategy involving a security or securities”, and FINRA reads the strategy part widely: it is “to be interpreted broadly and would include, among other things, an explicit recommendation to hold a security or securities.” A representative who explicitly tells a customer to keep holding a position has made a recommendation, and the suitability duty attaches to it.
The same paragraph lists four kinds of communication that fall outside the rule, “as long as they do not include (standing alone or in combination with other communications) a recommendation of a particular security or securities”.
Outside Rule 2111, until a particular security is recommended
- General financial and investment information2111.03(a)
Basic concepts such as risk and return, diversification, dollar cost averaging, compounded return and tax deferred investment; historic differences in asset-class returns based on standard market indices; effects of inflation; estimates of future retirement income needs; assessment of a customer’s investment profile.
- Employer plan information2111.03(b)
Descriptive information about an employer-sponsored retirement or benefit plan, participation in it, the benefits of participating, and the investment options it offers.
- Asset allocation models2111.03(c)
Models based on generally accepted investment theory, accompanied by disclosure of all material facts and assumptions, and compliant with Rule 2214 where the model is an investment analysis tool.
- Interactive investment materials2111.03(d)
Materials that incorporate the three kinds above.
For a small firm the list is a practical map of its education work. A retirement seminar on diversification and inflation sits inside the carve-out; the same seminar ending on “and this fund is how to do it” does not. The seminar slides are also a communication with the public, reviewed under a different rule, see FINRA Rule 2210.
Quantitative suitability: the account taken together
The third obligation looks past the single trade. Each recommendation can pass on its own and the account can still fail, because the test is the pattern.
The rule gives no number. “No single test defines excessive activity”, it says, and then names three factors that “may provide a basis for a finding” that the obligation was broken. Any threshold a firm uses to flag an account is its own surveillance choice, not a figure from the rule.
2111.05(c)
Turnover rate
How often the account's holdings are replaced by recommended trades.
2111.05(c)
Cost-equity ratio
What the trading costs the customer, set against the account's equity.
2111.05(c)
In-and-out trading
Buying and selling the same position over short stretches.
A firm of a few people may have no surveillance desk, so the practical question is who looks at activity and how often. A principal reviewing every trade sees each transaction but not always the pattern; an exception report run across accounts sees the pattern. Those reports are records in their own right: a broker-dealer keeps reports produced to review for unusual activity in customer accounts “until eighteen months after the date the report was generated” (17 CFR 240.17a-4(e)(8)). Firms that want the alerts built for them compare trade surveillance software, and our guide to trade surveillance sets out what the rules ask of it.
Institutional accounts
Rule 2111(b) lets a firm meet the customer-specific obligation for an institutional account in a different way, and only that obligation. “Institutional account” is the term defined in Rule 4512(c): the account of a bank, savings and loan, insurance company or registered investment company; an SEC- or state-registered investment adviser; or “any other person (whether a natural person, corporation, partnership, trust or otherwise) with total assets of at least $50 million.”
Rule 2111(b): both conditions
- (1)The firm's belief about the customer
The member or associated person has a reasonable basis to believe that the institutional customer “is capable of evaluating investment risks independently, both in general and with regard to particular transactions and investment strategies involving a security or securities”.
- (2)The customer's own statement
The institutional customer “affirmatively indicates that it is exercising independent judgment in evaluating the member’s or associated person’s recommendations”.
Where the institution has handed its decisions to an agent, “such as an investment adviser or a bank trust department, these factors shall be applied to the agent.” The statement in condition two can be given “on a trade-by-trade basis, on an asset-class-by-asset-class basis, or in terms of all potential transactions for its account” (2111.07). The rule does not prescribe its form. A dated, written statement in the account file is the one that is easiest to produce later, so collect it that way.
The records that show a recommendation was suitable
Rule 2111 names almost no records of its own. Two phrases ask for paper: a factor left out of the profile must be “documented with specificity”, and an institutional customer must “affirmatively indicate” its independent judgment. The rest of a suitability file is built from the SEC's broker-dealer record rules, FINRA's account-record rule and the supervision rule. Test a file with the questions the rules themselves raise; each one has a paper that answers it.
Seven questions about one recommendation, and the paper that answers each
| The question | The paper that answers it | Rule |
|---|---|---|
| Did the firm understand the product before recommending it? | A product review note: the risks and rewards read, who read them, the date | 2111.05(a) |
| What did the firm know about this customer? | The dated profile, all nine factors, on the new-account form | 2111(a); 17a-3(a)(17) |
| Why is a factor missing? | A reason written for this customer, not a form-wide box | 2111.04 |
| Why did it fit this customer? | A short note tying the recommendation to the profile | 2111.05(b) |
| Could the customer afford a continuing commitment? | The financial situation on the profile, and a note for recurring purchases | 2111.06 |
| Was the account traded too much? | The activity reports and how each flagged account was cleared | 2111.05(c); 17a-4(e)(8) |
| Did a principal look at the trade? | The principal's review of the transaction, evidenced in writing | 3110(b)(2) |
FINRA Rules 2111 and 3110(b)(2); 17 CFR 240.17a-3, 240.17a-4
Several of those papers have a retention period set by rule. The account record and the Reg BI record share one: “until at least six years after the earlier of the date the account was closed or the date on which the information was collected, provided, replaced, or updated.”
What to keep, and for how long
| Record | What it holds | Kept for | Rule |
|---|---|---|---|
| Account record, natural-person account | Name, tax ID, address, telephone, date of birth, employment status, annual income, net worth (excluding primary residence), the account’s investment objectives; whether the representative signed it and a principal approved or accepted it | 6 years after the earlier of closing or the information being collected, provided, replaced or updated | 17a-3(a)(17); 17a-4(e)(5) |
| Reg BI information, retail customer | All information collected from and provided to the retail customer under 15l-1, and the associated person responsible for the account | Same as the account record | 17a-3(a)(35); 17a-4(e)(5) |
| FINRA customer account information | Each update to the account information; the last update, or the original if never updated | 6 years after each update; 6 years after the account closes | FINRA 4512.01 |
| Communications about the recommendation | Emails, texts and memos sent and received relating to the business, with the names of who prepared and who reviewed outgoing correspondence | 3 years, the first 2 in an easily accessible place | 17a-4(b)(4); FINRA 3110.09 |
| Activity review reports | Reports produced to review for unusual activity in customer accounts | 18 months after the report is generated | 17a-4(e)(8) |
| Written supervisory procedures | Each version of the manual that sets out how recommendations are reviewed | 3 years after that version stops being used | 17a-4(e)(7) |
17 CFR 240.17a-3(a)(17), (a)(35); 240.17a-4(b), (e)(5), (e)(7), (e)(8); FINRA Rules 4512.01, 3110.09
The account record also runs on a clock of its own. The customer gets a copy soon after opening and again at set intervals, which is the firm's regular chance to catch a profile that has gone stale.
Account opened
17a-3(a)(17)(i)(B)(1)
Within 30 days of opening
Then a copy of the account record, or an alternate document with the same information, goes to the customer.
Every account in the cycle
17a-3(a)(17)(i)(B)(1)
At intervals no greater than 36 months
Then the copy goes out again.
Investment objectives change
17a-3(a)(17)(i)(B)(3)
On or before the 30th day after notice
Then the customer and the responsible associated person get the updated record.
Name or address change
17a-3(a)(17)(i)(B)(2)
On or before the 30th day after notice
Then a notice of the change goes to the old address, or to each joint owner, and to the associated person.
The account record and its 36-month copy apply only to accounts for which the firm is, or within the past 36 months was, required to make a suitability determination. A customer's neglect, refusal or inability to provide the information excuses the firm from obtaining it.
Every period above is in our books and records retention calculator, and the full broker-dealer record list is in our guide to FINRA Rule 4511. Where the records sit matters too: broker-dealer records must be kept in a form 17a-4(f) accepts, covered in SEC Rule 17a-4 and WORM storage.
A small broker-dealer's suitability routine
Put together, the rule and the record rules make a routine with seven moments in it. In a small firm several of them fall to the same principal, which is the argument for building them into the forms and systems the firm already uses rather than a separate suitability binder.
Seven moments in a recommendation's life
- 01Before a product goes on the shelf
Write down the reasonable-basis review: what was read about its risks and rewards, by whom, when.
2111.05(a)
- 02At account opening
Collect all nine profile factors on the new-account form, with a specific reason for any left out. The representative signs, a principal approves or accepts, and the customer gets a copy within 30 days.
2111(a); 2111.04; 17a-3(a)(17)
- 03At each recommendation
Decide which standard governs it and note why it fits the profile. A retail investor must already have Form CRS: it is due before or at the earliest of a recommendation, an order or the account opening.
2111.08; 2111.05(b); 17a-14(c)(1)
- 04As trades come in
A principal reviews transactions and the review is evidenced in writing; activity reports catch the pattern a single review misses.
3110(b)(2); 2111.05(c)
- 05When objectives change
Send the customer and the representative the updated account record on or before the 30th day after notice.
17a-3(a)(17)(i)(B)(3)
- 06At least every 36 months
Send the account record again and treat any correction the customer returns as a profile update.
17a-3(a)(17)(i)(B)(1)
- 07When the procedures change
Keep the superseded version for three years after its use ends.
17a-4(e)(7)

Periods as the rule words state them. Where your firm must choose a period, ask your compliance counsel.
The principal's review in step four is the supervision rule at work, set out in our guide to FINRA Rule 3110. Firms that want the account records, review queue and procedures in one system compare broker-dealer compliance software. This guide explains the rule; it is not legal advice, and your compliance counsel should check your procedures against the full text on FINRA's Rule 2111 page.
Questions small broker-dealers ask
Does Rule 2111 still apply now that Regulation Best Interest exists?
Yes, to recommendations that are not subject to Regulation Best Interest. The rule says it “shall not apply to recommendations subject to SEA Rule 15l-1”, so the line between the two is the scope of Reg BI. Settle where that line falls for your customers with your compliance counsel.
FINRA Rule 2111.08
Is telling a customer to hold a security a recommendation?
An explicit recommendation to hold is. FINRA reads “investment strategy” broadly and names “an explicit recommendation to hold a security or securities” as included.
FINRA Rule 2111.03
Can a customer sign away suitability in the account agreement?
No. “A member or associated person cannot disclaim any responsibilities under the suitability rule.”
FINRA Rule 2111.02
Is there a turnover number that makes trading excessive?
Not in the rule. “No single test defines excessive activity”; the turnover rate, the cost-equity ratio and in-and-out trading are factors that may support a finding. A threshold in your exception reports is your own choice.
FINRA Rule 2111.05(c)
What if a customer will not tell us everything?
For the SEC account record, a customer's “neglect, refusal, or inability” to provide the information excuses the firm from obtaining it. Rule 2111 still asks for a reasonable basis to believe the recommendation is suitable, so record the refusal and weigh what you do know before recommending.
17 CFR 240.17a-3(a)(17)(i)(C); FINRA Rule 2111(a)
Does Rule 2111 apply to an SEC-registered investment adviser?
Not to a stand-alone adviser: FINRA rules bind FINRA member firms. An adviser's program runs under the Advisers Act, see RIA compliance. A firm registered both ways applies 2111 to its broker-dealer recommendations.
