Executive Summary

On April 3, 2006, NASD filed with the Securities and Exchange Commission (SEC) for immediate effectiveness a rule change to amend NASD Rules 2520 and 2522 that revised the margin requirements to recognize specific additional complex option spread strategies for purposes of determining required margin, and has amended the provisions relating to "permitted offsets" for certain listed option transactions.1 Rules 2520 and 2522, as amended, are set forth in Attachment A of this Notice. The effective date and the implementation date of the amendments was April 3, 2006.

Questions/Further Information

Questions regarding this Notice may be directed to Susan M. DeMando, Associate Vice President, Financial Operations, at (202) 728-8411; or Kathryn M. Moore, Assistant General Counsel, Office of General Counsel, Regulatory Policy and Oversight, at (202) 974-2974.

Background and Discussion

NASD has amended Rule 2520 to recognize specific additional complex option spread strategies for purposes of determining required margin, and has amended the provisions relating to "permitted offsets" for certain listed option transactions. In addition, NASD amended Rule 2522 to include definitions relating to the amendments to Rule 2520 and to make certain other conforming changes. The amendments to Rules 2520 and 2522 are consistent with recent margin rule amendments by the New York Stock Exchange (NYSE) and the Chicago Board Options Exchange (CBOE), which were approved by the SEC.2

Complex Option Spread Strategies

NASD has amended Rule 2520 and the corresponding definitions in Rule 2522 to recognize specific additional complex option spread strategies, and has set margin requirements commensurate with the risk of such spread strategies. These complex option spread strategies are the net result of combining two or more spread strategies that were already recognized in NASD's margin rules. The netting of contracts in option series common to each of the already recognized spreads in an aggregation reduces it to the complex spread strategies noted below. The purpose and benefit of the recent amendments is to set levels of margin that more precisely represent actual net risk of the option positions in the account and enable customers to implement these strategies more efficiently.

To be eligible for the margin requirements set forth below, a complex spread must be consistent with one of the seven patterns specified below. The expiration months and the sequence of the exercise prices must correspond to the same pattern, and the intervals between the exercise prices must be equal.

Members are required to obtain initial and maintenance margin for the subject complex spreads, whether established outright or through netting, of not less than the sum of the margin required on each basic spread in the equivalent aggregation.

The basic requirements are as follows: (a) the complex option spreads must be carried in a margin account; and (b) European-style options3 are prohibited for complex spread combinations having a long option series that expires after the other option series (i.e., those that involve a time spread such as items 5, 6, and 7 below). Only American-style options may be used in these combinations. Additionally, the intervals between exercise prices must be equal, and each complex spread must comprise four option series, with the exception of item 4 below, which must comprise three option series.

The sum of the margin required on each currently recognized spread in each of the applicable aggregations renders margin requirements for the subject complex spread strategies as stated below. The additional complex option spread strategies and maintenance margin requirements are as follows:

(1) A Long Condor Spread is comprised of two long Butterfly Spreads. The rule requires initial and maintenance margin of full cash payment of the net debit incurred when this spread strategy is established. Full payment of the net debit incurred will cover any potential risk to the carrying broker-dealer.
(2) A Short Iron Butterfly Spread is comprised of one long Butterfly Spread and one short Box Spread. The establishment of a long Butterfly Spread results in a margin requirement equal to the net debit incurred. The establishment of a short Box Spread requires margin equal to the aggregate difference between the exercise prices. The net proceeds from the sale of short option components may be applied to the margin requirement. Accordingly, to cover the risk to the carrying broker-dealer, the rule requires a deposit of the aggregate exercise price differential. The net credit received may be applied to the deposit required.
(3) A Short Iron Condor Spread is comprised of two long Butterfly Spreads and one short Box Spread. The establishment of long Butterfly Spreads results in a margin requirement equal to the net debit incurred. The establishment of a short Box Spread requires margin equal to the difference in the strike price. Accordingly, to cover the risk to the carrying broker-dealer, the rule requires a deposit of the aggregate exercise price differential. The net credit received may be applied to the deposit required.
(4) A Long Calendar Butterfly Spread is comprised of one long Calendar Spread and one long Butterfly Spread. The rule requires initial and maintenance margin of full cash payment of the net debit incurred when this spread strategy is established. Full payment of the net debit incurred will cover any potential risk to the carrying broker-dealer.
(5) A Long Calendar Condor Spread is comprised of one long Calendar Spread and two long Butterfly Spreads. The rule requires initial and maintenance margin of full cash payment of the net debit incurred when this spread strategy is established. Full payment of the net debit incurred will cover any potential risk to the carrying broker-dealer.
(6) A Short Calendar Iron Butterfly Spread is comprised of one long Calendar Spread plus one long Butterfly Spread and one short Box Spread. To cover the risk to the carrying broker-dealer, the rule requires a deposit of the aggregate exercise price differential. The net credit received may be applied to the deposit required.
(7) A Short Calendar Iron Condor Spread is comprised of one Long Calendar Spread plus two long Butterfly Spreads and one short Box Spread. To cover the risk to the carrying broker-dealer, the rule requires a deposit of the aggregate exercise price differential. The net credit received may be applied to the deposit required.

Permitted Offsets

Rule 2520(f)(2)(J) addresses margin requirements for members that clear and carry the listed options transactions of registered specialists, registered market makers or registered traders in options, and recognizes certain offset positions in establishing the margin requirements. Prior to the recent amendments, the rule limited permitted offsets for these parties to options series that are "in or at the money," which was defined to mean "the current market price of the underlying security is not more than two standard exercise intervals below (with respect to a call option) or above (with respect to a put option) the exercise price of the option."

Recently, various option exchanges have provided for the listing of options with onedollar strike intervals in a number of classes. As a result, the use of securities to hedge options series that have one-dollar strike intervals has unintentionally become more restrictive. The recent amendments eliminated the definition of "in or at the money," thereby eliminating the two standard exercise interval limitation for listed options. In addition, the amended rule requires permitted offset transactions to be effected for specialist or market-making purposes such as hedging, risk reduction, rebalancing of positions, liquidation or accommodation of customer orders, or other similar specialist or market-making purposes.

The amendments to Rules 2520 and 2522 became effective April 3, 2006.

(J)
(i) Registered specialists, market makers or traders—Notwithstanding the other provisions of this subparagraph (f)(2), a member may clear and carry the listed option transactions of one or more registered specialists, registered market makers or registered traders in options (whereby[which] registered traders are deemed specialists for all purposes under the Act, pursuant to the rules of a national securities exchange) (hereinafter referred to as "specialist(s)"), upon a "Good Faith" margin basis satisfactory to the concerned parties, provided the "Good Faith" margin requirement[s] is not less than the Net Capital haircut deduction of the member [organization] carrying the transaction pursuant to SEC Rule 15c3-1 under the Act. In lieu of collecting the "Good Faith" margin requirement, a carrying member [organization] may elect to deduct in computing its Net Capital the amount of any deficiency between the equity maintained in the account and the "Good Faith" margin required.

For purposes of this paragraph (f)(2)(J), a permitted offset position means, in the case of an option in which a specialist or market maker makes a market, a position in the underlying asset or other related assets, and in the case of other securities in which a specialist or market maker makes a market, a position in options overlying the securities in which a specialist or market maker makes a market. Accordingly, a specialist or market maker in options may establish, on a share-for-share basis, a long or short position in the securities underlying the options in which the specialist or market maker makes a market, and a specialist or market maker in securities other than options may purchase or write options overlying the securities in which the specialist or market maker makes a market, if the account holds the following permitted offset positions:
a. A short option position which[ is "in or at the money" and] is not offset by a long or short option position for an equal or greater number of shares of the same underlying security which is "in the money";
b. A long option position which[ is "in or at the money" and] is not offset by a long or short option position for an equal or greater number of shares of the same underlying security which is "in the money";
c. A short option position against which an exercise notice was tendered;
d. A long option position which was exercised;
e. A net long position in a security (other than an option) in which a specialist or market maker makes a market;
f. A net short position in a security (other than an option) in which the specialist or market maker makes a market; or
g. A specified portfolio type as referred to in SEC Rule 15c3-1, including its appendices, or any applicable SEC staff interpretation or no-action position.
Permitted offset transactions must be effected for specialist or market making purposes such as hedging, risk reduction, rebalancing of positions, liquidation, or accommodation[s] of customer orders, or other similar [market making]specialist or market maker purpose. The specialist or market maker must be able to demonstrate compliance with this provision.
 
For purposes of this paragraph (f)(2)(J),[ the term "in or at the money" means the current market price of the underlying security is not more than two standard exercise intervals below (with respect to a call option) or above (with respect to a put option) the exercise price of the option;] the term "in the money" means the current market price of the underlying asset or index is not below (with respect to a call option) or above (with respect to a put option) the exercise price of the option; and, the term "overlying option" means a put option purchased or a call option written against a long position in an underlying asset; or a call option purchased or a put option written against a short position in an underlying asset.
(ii) Securities, including options, in such accounts shall be valued conservatively in the light of current market prices and the amount which might be realized upon liquidation. Substantial additional margin must be required or excess [n]Net [c]Capital maintained in all cases where the securities carried:
a. through b. No Change.
c. in one or more or all accounts, including proprietary accounts combined, are such that they cannot be liquidated promptly or represent undue concentration of risk in view of the carrying member's [n]Net [c]Capital and its overall exposure to material loss.
(K) through (L) No Change.
(M) Cash account transactions—A member may make option transactions in a customer's cash account, provided that:
(i) No Change.
(ii) Spreads. A European-style cash-settled index stock group option or stock index warrant carried in a short position is deemed a covered position, and eligible for the cash account, provided a long position in a European-style cash-settled stock group index option, or stock index warrant having the same underlying component or index that is based on the same aggregate current underlying value, is held in or purchased for the account on the same day, provided that:
a. through b. No Change.
c. there is held in the account at the time the positions are established, or received into the account promptly thereafter:
1. cash or cash equivalents of not less than any amount by which the [aggregate] exercise price of the long call or call warrant (short put or put warrant) exceeds the [aggregate] exercise price of the short call or call warrant (long put or put warrant), to which [requirement of] net proceeds from the sale of the short position may be applied, or
2. an escrow agreement.

The escrow agreement must certify that the bank holds for the account of the customer as security for the agreement i. cash, ii. cash equivalents, or iii. a combination thereof having an aggregate market value at the time the positions are established of not less than any amount by which the [aggregate] exercise price of the long call or call warrant (short put or put warrant) exceeds the [aggregate] exercise price of a short call or call warrant (long put or put warrant) and that the bank will promptly pay the member such amount in the event the account is assigned an exercise notice or that the bank will promptly pay the member funds sufficient to purchase a warrant sold short in the event of a buy-in.
d. No Change.
(iii) Long Butterfly Spreads, Short Butterfly Spreads, Long Condor Spreads, Short Iron Butterfly Spreads, or Short Iron Condor Spreads. Put or call options carried in a short position are deemed covered positions and eligible for the cash account provided that the account contains long positions of the same type which in conjunction with the short options, constitute a long butterfly spread, short butterfly spread, long condor spread, short iron butterfly spread, or short iron condor spread as defined in Rule 2522 and provided that:
a. through d. No Change.
e. all components options expire concurrently;
[e]f. with respect to a long butterfly spread or long condor spread as defined in Rule 2522, the net debit is paid in full; and
[f]g. with respect to a short butterfly spread, short iron butterfly spread or short iron condor spread as defined in Rule 2522, there is held in the account at the time the positions are established or received into the account promptly thereafter:
1. cash or cash equivalents of not less than the amount of the [aggregate] difference between the two lowest exercise prices with respect to short butterfly spreads comprised of call options or the [aggregate] difference between the two highest exercise prices with respect to short butterfly spreads comprised [or] of put options, to which [requirement] the net proceeds from the sale of short option components may be applied; or
2. an escrow agreement.

The escrow agreement must certify that the bank holds for the account of the customer as security for the agreement i. cash, ii. cash equivalents or iii. a combination thereof having an aggregate market value at the time the positions are established of not less than the amount of the [aggregate] difference between the two lowest exercise prices with respect to short butterfly spreads comprised of calls or the [aggregate] difference between the two highest exercise prices with respect to short butterfly spreads comprised of puts and that the bank will promptly pay the member such amount in the event the account is assigned an exercise notice on the call (put) with the lowest (highest) exercise price.
(iv) Box Spreads. Puts and calls carried in a short position are deemed covered positions and eligible for the cash account provided that the account contains long positions which in conjunction with the short options constitute a box spread as defined in Rule 2522 provided that:
a. through d. No Change.
e. all component options expire concurrently;
[e]f. with respect to a long box spread as defined in Rule 2522, the net debit is paid in full; and
[f]g. with respect to a short box spread as defined in Rule 2522, there is held in the account at the time the positions are established, or received into the account promptly thereafter:
1. cash or cash equivalents of not less than the amount of the [aggregate] difference between the exercise prices, to which [requirement] the net proceeds from the sale of short option components may be applied; or
2. an escrow agreement.

The escrow agreement must certify that the bank holds for the account of the customer as security for the agreement i. cash, ii. cash equivalents or iii. a combination thereof having an aggregate market value at the time the positions are established of not less than the amount of the [aggregate] difference between the exercise prices and that the bank will promptly pay the member such amount in the event the account is assigned an exercise notice on either short option.
