§ 220.128 Treatment of simultaneous long and short positions in the same margin account when put or call options or combinations thereof on such stock are also outstanding in the account. ( a ) The Board was recently asked whether under Regulation T, “Credit by Brokers and Dealers” (12 CFR part 220), if there are simultaneous long and short positions in the same security in the same margin account (often referred to as a short sale “against the box”), such positions may be used to supply the place of the deposit of margin ordinarily required in connection with the guarantee by a creditor of a put or call option or combination thereof on such stock.
( b ) The applicable provisions of regulation T are § 220.3(d)(3) and (5) and § 220.3(g)(4) and (5) which provide as follows: (d) * * * the adjusted debit balance of a general account * * * shall be calculated by taking the sum of the following items:
(3) The current market value of any securities (other than unissued securities) sold short in the general account plus, for each security (other than an exempted security), such amount as the board shall prescribe from time to time in § 220.8(d) (the supplement to regulation T) as the margin required for such short sales, except that such amount so prescribed in such § 220.8(d) need not be included when there are held in the general account * * * the same securities or securities exchangeable or convertible within 90 calendar days, without restriction other than the payment of money, into such securities sold short;
(5) The amount of any margin customarily required by the creditor in connection with his endorsement or guarantee of any put, call, or other option;
(g) * * * (4) Any transaction which serves to meet the requirements of paragraph (e) of this section or otherwise serves to permit any offsetting transaction in an account shall, to that extent, be unavailable to permit any other transaction in such account. (5) For the purposes of this part (regulation T), if a security has maximum loan value under paragraph (c)(1) of this section in a general account, or under § 220.4(j) in a special convertible debt security account, a sale of the same security (even though not the same certificate) in such account shall be deemed to be a long sale and shall not be deemed to be or treated as a short sale.
( c ) Rule 431 of the New York Stock Exchange requires that a creditor obtain a minimum deposit of 25 percent of the current market value of the optioned stock in connection with his issuance or guarantee of a put, and at least 30 percent in the case of a call (and that such position be “marked to the market”), but permits a short position in the stock to serve in lieu of the required deposit in the case of a put and a long position to serve in the case of a call. Thus, where the appropriate position is held in an account, that position may serve as the margin required by § 220.3(d)(5).
( d ) In a short sale “against the box,” however, the customer is both long and short the same security. He may have established either position, properly margined, prior to taking the other, or he may have deposited fully paid securities in his margin account on the same day he makes a short sale of such securities. In either case, he will have directed his broker to borrow securities elsewhere in order to make delivery on the short sale rather than using his long position for this purpose (see also 17 CFR 240.3b-3).
( e ) Generally speaking, a customer makes a short sale “against the box” for tax reasons. Regulation T, however, provides in § 220.3(g) that the two positions must be “netted out” for the purposes of the calculations required by the regulation. Thus, the board concludes that neither position would be available to serve as the deposit of margin required in connection with the endorsement by the creditor of an option.
( f ) A similar conclusion obtains under § 220.3(d)(3). That section provides, in essence, that the margin otherwise required in connection with a short sale need not be included in the account if the customer has in the account a long position in the same security. In § 220.3(g) (4), however, it is provided that “[A]ny transaction which * * * serves to permit any offsetting transaction in an account shall, to that extent, be unavailable to permit any other transaction in such account.” Thus, if a customer has, for example, a long position in a security and that long position has been used to supply the margin required in connection with a short sale of the same security, then the long position is unavailable to serve as the margin required in connection with the creditor's endorsement of a call option on such security.
( g ) A situation was also described in which a customer has purported to establish simultaneous offsetting long and short positions by executing a “cross” or wash sale of the security on the same day. In this situation, no change in the beneficial ownership of stock has taken place. Since there is no actual “*contra*” party to either transaction, and no stock has been borrowed or delivered to accomplish the short sale, such fictitious positions would have no value for purposes of the Board's margin regulations. Indeed, the adoption of such a scheme in connection with an overall strategy involving the issuance, endorsement, or guarantee of put or call options or combinations thereof appears to be manipulative and may have been employed for the purpose of circumventing the requirements of the regulations.
