RULE 105 OF REGULATION M: SHORT SELLING IN 

CONNECTION WITH A PUBLIC OFFERING

I. Introduction

Rule 105 generally prohibits purchasing securities in follow-on and 

secondary offerings when the purchaser has effected short sales in 

the securities within a specified amount of time prior to the pricing 

of an offering.2 

From January 2010 through the present, the Commission has 

collected disgorgement, penalties, and interest in excess of $42

million based on violations of Rule 105 of Regulation M (“Rule 

105” or “the Rule”). In that time frame, the Commission has settled 

over 40 actions in which it found that firms and/or individuals have

violated Rule 105. These enforcement actions and the observations 

from examiners of the National Exam Program (“NEP”) suggest the 

need for firms to consider certain control procedures that may improve firms’ compliance with 

Rule 105 of Regulation M.

3 Additionally, the settled enforcement actions listed in Appendix B

highlight the serious consequences of trading activities that fail to comply with Rule 105. 

II. Overview of Rule 105 of Regulation M

A fundamental goal of Rule 105 of Regulation M is protecting the independent pricing 

mechanisms of the securities markets so that offering prices result from the natural forces of 

supply and demand unencumbered by artificial forces. The Rule is particularly concerned with

17 CFR 242.105. Appendix A includes several resources that may be used to better understand the 

requirements of Rule 105 of Regulation M such as: the adopting, proposing and interpretive releases issued by 

the Commission; and interpretive guidance and frequently asked questions issued by the SEC staff.

In this Alert

Topic: Compliance issues 

related to Rule 105 of Regulation 

M, which governs short selling 

prior to pricing of certain 

offerings.

short selling that could artificially depress market prices. Generally, the offering prices of 

follow-on and secondary offerings are set at a discount to a stock’s closing price just prior to 

pricing. A person who expects to receive offering shares may attempt to profit by aggressively 

short-selling the security just prior to the pricing of the offering, thereby depressing the offering 

price, and then purchasing lower-priced securities in the offering.

In 2007, the Commission amended Rule 105 in order to address the proliferation of trading 

strategies designed to conceal violations of the prior rule and in light of evolving trading 

strategies. As amended, Rule 105 makes it unlawful for a person to purchase securities in a firm 

commitment equity offering from an underwriter or broker-dealer participating in the offering if

that person sold short the security that is the subject of the offering during the Rule 105 restricted 

period, absent an available exception.

4

 

Rule 105 provides three exceptions: the “bona fide purchase” provision; an exception for 

separate accounts; and an exception for investment companies.

5

 First, the “bona fide purchase”

exception generally provides that persons can purchase securities in the offering even if they sell 

short during the Rule 105 restricted period as long as they make a bona fide purchase equivalent 

in quantity to the amount of the restricted period short sale(s) prior to pricing. Eligibility for the 

bona fide purchase exception depends on compliance with specific timing and trade reporting 

requirements that are intended to allow the market to see and take into account purchasing 

activity in the stock prior to the pricing of the offering. 

Second, the limited exception for trading in separate accounts generally allows a purchase of the 

offered securities in an account of a person where such person sold short in another account 

during the restricted period, if decisions regarding securities transactions for each account are 

made separately and without any coordination of trading or cooperation among or between the 

accounts.6 Whether an account may be considered separate for purposes of this exception 

depends on the facts and circumstances. However, the Commission noted there were several 

indicators that may assist in demonstrating that accounts are separate, such as:

 The accounts have separate and distinct investment and trading strategies and objectives; 

 

4 The Rule 105 restricted period is typically the period beginning five days before the pricing of the offered 

securities and ending with such pricing. Specifically, Rule 105(a) provides as follows: In connection with an 

offering of equity securities for cash pursuant to a registration statement or notification on Form 1-A or Form 

1-E filed under the Securities Act of 1933 (“offered securities”), it shall be unlawful for any person to sell short 

(as defined in Rule 200(a) of Regulation SHO) the security that is the subject of the offering and purchase the 

offered securities from an underwriter or broker or dealer participating in the offering if such short sale was 

effected during the period (“Rule 105 restricted period”) that is the shorter of the period: (1) Beginning five 

business days before the pricing of the offered securities and ending with such pricing; or (2) Beginning with 

the initial filing of such registration statement or notification on Form 1-A or Form 1-E and ending with the 

pricing. 17 CFR 242.105(a).

 Personnel for each account do not coordinate trading among or between the accounts; 

 Information barriers separate the accounts, and information about securities positions or 

investment decisions is not shared between accounts; 

 Each account maintains a separate profit and loss statement; 

 There is no allocation of securities between or among accounts; and 

 Personnel with oversight or managerial responsibility over multiple accounts in a single 

entity or affiliated entities, and account owners of multiple accounts, do not have 

authority to execute trading in individual securities in the accounts and in fact, do not 

execute trades in the accounts, and do not have the authority to pre-approve trading 

decisions for the accounts and, in fact, do not pre-approve trading decision for the 

accounts.7

Third, the investment company exception allows a registered fund (or series of such fund) to 

participate in an offering, even if another series of the registered fund or an affiliated registered 

fund (or series of such fund) sold short during the restricted period.8 

III. Corrective Actions Implemented to Comply with Rule 105 of Regulation M

Recent SEC enforcement actions have specified, and NEP examinations have observed, deficient 

practices relating to Rule 105.9 Rule 105 does not require intent on the part of the short seller to 

engage in a prohibited transaction; one violates the rule if such person sells short the security that 

is the subject of the offering during the restricted period (and does not fit into one of the Rule’s 

three exceptions) and then purchases shares of that security in the offering. To be in compliance

with Rule 105, a person that for any reason has sold short shares of a security that is the subject 

of an offering during the restricted period must generally either refrain from purchasing shares of 

that security in the offering, or rely on an exception. Firms are reminded that, in order to 

advance compliance with Rule 105, it is important to provide training to their employees

17 CFR 242.105(b)(3). For example, an individual fund within a fund complex is generally not prohibited by 

Rule 105 from purchasing an offered security if another fund within the same complex (i.e., an affiliate) sold 

short the same security within the restricted period. Exchange Act Release No. 56206, 72 Fed. Reg. 45,094

(August 10, 2007) at 45,100.

See, e.g., Carlson Capital, L.P., Exchange Act Rel. No. 62982 (Sept. 23, 2010)(settled matter)(according to 

SEC order, investment personnel either misunderstood or were unaware of Rule 105’s requirements, the firm’s 

compliance manual did not address it, and the firm lacked policies and procedures sufficient to prevent 

violations).
4

regarding the application of the Rule, develop and implement policies and procedures reasonably 

designed to achieve compliance with the Rule, and enforce those policies and procedures.10 

In determining the penalties associated with the violations in settled Rule 105 enforcement 

actions, the Commission has considered, among other factors, whether the firms implemented 

remedial efforts, such as developing and implementing policies, procedures and controls to 

prevent or detect Rule 105 violations in determining the appropriate resolution in those cases.11

Additionally, in examination summary letters to firms, the NEP staff has specifically commented 

on inadequate policies and procedures that fail to identify, mitigate and manage risks involving

short sales in connection with follow-on or secondary offerings. Effective and enforced policies,

procedures and controls can promote compliance with Rule 105. 

 

Even though firms or individuals may take prompt remedial steps to address violations of Rule 

105 brought to their attention, these same remedial steps, had they been proactively 

implemented, may have prevented the violations.

12

 After-the-fact remediation would not absolve 

a firm or individual from the violation of Rule 105. 

Robust procedures, as well as a system for applying such procedures, can help prevent and 

detect, insofar as practicable, violations of Rule 105 by a broker, dealer, investment adviser, or 

investment company. 

IV. Conclusion

This alert informs investment advisers, investment companies and broker-dealers about the 

importance of complying with Rule 105. It also describes some practices and controls that firms 

have employed for compliance with Rule 105. The staff hopes that by sharing these 

observations, it will better encourage firms and individuals who are subject to compliance with

Global Investors, L.P., Exchange Act Rel. No. 64763 (June 28, 2011)(settled matter); UBS O’Connor, LLC,

Exchange Act Rel. No. 69680 (June 3, 2013)(settled matter). 

11 See, e.g., Touradji Capital Management, L.P., Exchange Act Rel. No. 65923 (Dec. 9, 2011) (settled matter). In 

this administrative proceeding, an investment adviser violated Rule 105 of Regulation M by purchasing 

securities in certain public offerings after having sold short the securities during the five business days prior to 

the pricing of the public offerings (absent a relevant exception), realizing profits of $833,976. The adviser was 

required to disgorge these profits, as well as pay a civil penalty of $350,000 and prejudgment interest of 

$119,360. In determining to accept the settlement, the Commission considered the adviser’s remedial efforts,

including the development and implementation of policies, procedures and controls to prevent or detect Rule 

105 violations.

12 See, e.g., Harbinger Capital Partners, Exchange Act Rel. No. 67279 (June 27, 2012)(settled matter)(firm 

developed employee training and new policies, procedures and controls to prevent or detect Rule 105 violations 

once it learned of its past violations); Brookside Capital, LLC, Exchange Act Rel. No. 64764 ( June 28, 

2011)(settled matter)(firm developed and implemented policies, procedures and training programs related to 

Rule 105 compliance).

Rule 105 to apply greater focus on regulations governing short selling in connection with a 

public offering, implement compliance procedures to manage applicable transactions, and 

actively monitor transactions for potential violative conduct. 

NEP staff welcomes comments and suggestions about how the Commission’s examination 

program can better fulfill its mission to promote compliance, prevent fraud, monitor risk, and 

inform SEC policy. If you suspect or observe activity that may violate the federal securities laws 

or otherwise operates to harm investors, please notify us at

This Risk Alert is intended to highlight for firms risks and issues that the staff has identified in the course of 

examinations regarding compliance with Rule 105 of Regulation M. In addition, this Risk Alert describes factors 

that firms may consider to (i) assess their supervisory, compliance and/or other risk management systems 

related to these risks, and (ii) make any changes, as may be appropriate, to address or strengthen such systems. 

These factors are not exhaustive, nor will they constitute a safe harbor. Other factors besides those described in 

this Risk Alert may be appropriate to consider, and some of the factors may not be applicable to a particular 

firm’s business. While some of the factors discussed in this Risk Alert reflect existing regulatory requirements,

they are not intended to alter such requirements. Moreover, future changes in laws or regulations may 

supersede some of the factors or issues raised here. The adequacy of supervisory, compliance and other risk 

management systems can be determined only with reference to the profile of each specific firm and other facts 

and circumstances.
