5.4 Short Sales, Locates and SHO Closeouts

Short Sale Mechanics & Settlement Risks

In a short sale transaction, an investor anticipates that a security's price will decline. The operational lifecycle unfolds in four distinct stages:

1. Locate and Borrow: Prior to execution, the broker-dealer confirms that shares are available to borrow.
2. Execution and Delivery: The short seller sells the borrowed shares in the open market. On regular-way settlement date (T+1), the broker-dealer delivers the borrowed shares to the National Securities Clearing Corporation (NSCC) to satisfy settlement, crediting the customer's account with the short sale proceeds.
3. Open Position Management: While the position remains open, the customer maintains required maintenance margin equity, compensates the lender for any declared dividends, and absorbs any ongoing borrow fees.
4. Replacement (Covering): To close the short position, the customer buys replacement shares in the market, which are returned to the lending institution, terminating the stock loan and releasing the cash collateral.

Settlement Risk: If the broker-dealer is unable to borrow the required shares or if the lending institution recalls the loaned stock and no replacement shares can be located, the clearing broker-dealer faces a fail to deliver (FTD) at the NSCC, triggering severe operational penalties under SEC Regulation SHO.

SEC Regulation SHO Regulatory Framework

Enacted under the Securities Exchange Act of 1934, Regulation SHO modernizes short sale regulation, addresses abusive short selling and settlement failures; not every short sale without an actual preborrow is unlawful, and ensures timely trade settlement across all U.S. equity markets.

1. Rule 203(b)(1) — The Locate Requirement

Under Regulation SHO Rule 203(b)(1), a broker-dealer may not accept a short sale order in any equity security from another person, or execute a short sale for its own proprietary account, unless the broker-dealer has:

1. Borrowed the security, or entered into a bona fide arrangement to borrow the security; or
2. Reasonable grounds to believe that the security can be borrowed so that it can be delivered on the date delivery is due.

Easy-to-Borrow (ETB) Lists

Broker-dealers commonly satisfy the "reasonable grounds" standard for liquid equities by relying on an Easy-to-Borrow (ETB) List. Under SEC regulatory interpretations, an ETB list provides legally acceptable reasonable grounds only if:

• The list is formally documented and updated at least daily;
• The information on the list is less than 24 hours old at the time of order execution; and
• The securities on the list exhibit continuous, proven, and high liquid supply, demonstrating that borrow requests are routinely and reliably fulfilled without failure.

Hard-to-Borrow (HTB) Procedures

Securities that do not meet ETB criteria cannot be shorted based on automated list reliance. Operations personnel must obtain an affirmative individual locate from an authorized lending desk before the short sale order can be accepted or executed. The operations log must record the security identifier, share quantity, lending counterparty source, locate identification number, and the timestamp.

2. Rule 203(c)(6) — Threshold Securities

Regulation SHO establishes specific operational criteria to identify equity securities experiencing persistent, severe settlement delivery failures. A security is formally designated as a Threshold Security if it satisfies four statutory criteria:

1. The security is an equity issue of an issuer registered under Section 12 or required to file reports under Section 15(d) of the Securities Exchange Act of 1934;
2. There is an aggregate fail to deliver position for five consecutive settlement days at a registered clearing agency (NSCC);
3. The aggregate fail to deliver position is 10,000 shares or more; AND
4. The aggregate fail to deliver position equals at least 0.5% (one-half of one percent) of the issuer's total shares outstanding.

Each self-regulatory organization (SRO), including FINRA, NYSE, and Nasdaq, compiles and publishes a daily Threshold Security List identifying all securities meeting this criteria. When a security appears on the threshold list, clearing firms face enhanced regulatory oversight and mandatory buy-in timelines.

3. Rule 204 — Mandatory Close-Out Requirements for Fails to Deliver

To safeguard settlement integrity, Regulation SHO Rule 204 mandates that participant clearing broker-dealers at registered clearing agencies must promptly close out all fail to deliver positions across all equity securities.

Mandatory Close-Out Timelines

Rule 204 establishes strict statutory buy-in deadlines based on the underlying nature of the transaction:

• Short Sale Fails (Rule 204(a)): If a fail to deliver position at the clearing agency results from a short sale, the participant clearing broker-dealer must close out the fail to deliver position by purchasing or borrowing securities of like kind and quantity no later than the beginning of regular trading hours on the settlement day immediately following the settlement date.
  • In the modern T+1 settlement environment, settlement occurs on T+1. Therefore, the mandatory close-out for short sale fails must take place by market open on T+2 (settlement date plus one business day; historically known as T+3 under the former T+2 settlement framework).
• Long Sale Fails (Rule 204(a)(1)): If the fail to deliver position is attributable to a long sale (e.g., operational delays in processing restricted physical stock certificates or custody delivery delays), the participant has until the beginning of regular trading hours on the third settlement day following the settlement date to close out the fail.
  • In a T+1 settlement environment, this corresponds to market open on T+4 (settlement date plus three business days; historically known as T+5 under the former T+2 settlement framework).
• Bona Fide Market Making Fails (Rule 204(a)(3)): Fails resulting from bona fide market making activities by registered market makers are granted the same close-out window as long sales: market open on the third settlement day following the settlement date (market open on T+4 under T+1 settlement).

Rule 204(b) Penalty: The Mandatory Pre-Borrow Requirement

If a participant clearing broker-dealer fails to close out an open fail to deliver position within the mandated Rule 204 timeframe, the clearing firm—and any introducing broker-dealer that clears through it—is subjected to the severe mandatory pre-borrow penalty:

• The broker-dealer is legally prohibited from executing any short sales in that specific security, for its own proprietary account or for any customer account, without first pre-borrowing the security (meaning the shares must be actually borrowed or an irrevocable bona fide agreement to borrow must be executed prior to order execution).
• The firm can no longer rely on Easy-to-Borrow lists or general locate assumptions.
• This pre-borrow restriction remains in effect until the open fail to deliver position is completely and successfully resolved by a bona fide buy-in purchase that has fully settled at the registered clearing agency.
