PART 41_SECURITY FUTURES PRODUCTS--Table of Contents
 
           Subpart E_Customer Accounts and Margin Requirements
 
Sec.  41.46  Type, form and use of margin.

    (a) When margin is required. Margin is required to be deposited 
whenever the required margin for security futures and related positions 
in an account is not satisfied by the equity in the account, subject to 
adjustment under paragraph (c) of this section.
    (b) Acceptable margin deposits. (1) The required margin may be 
satisfied by a deposit of cash, margin securities (subject to paragraph 
(b)(2) of this section), exempted securities, any other asset permitted 
under Regulation T to satisfy a margin deficiency in a securities margin 
account, or any combination thereof, each as valued in accordance with 
paragraph (c) of this section.
    (2) Shares of a money market mutual fund may be accepted as a margin 
deposit for purposes of this Regulation (Subpart E, Sec. Sec.  41.42 
through 41.49), Provided that:
    (i) The customer waives any right to redeem the shares without the 
consent of the security futures intermediary and instructs the fund or 
its transfer agent accordingly;
    (ii) The security futures intermediary (or clearing agency or 
derivatives clearing organization with which the shares are deposited as 
margin) obtains the right to redeem the shares in cash, promptly upon 
request; and
    (iii) The fund agrees to satisfy any conditions necessary or 
appropriate to ensure that the shares may be redeemed in cash, promptly 
upon request.
    (c) Adjustments--(1) Futures accounts. For purposes of this section, 
the equity in a futures account shall be computed in accordance with the 
margin rules applicable to the account, subject to the following:
    (i) A security future shall have no value;
    (ii) Each net long or short position in a listed option on a 
contract for future delivery shall be valued in accordance with the 
margin rules applicable to the account;
    (iii) Except as permitted in paragraph (e) of this section, each 
margin equity security shall be valued at an amount no greater than its 
Regulation T collateral value;
    (iv) Each other security shall be valued at an amount no greater 
than its current market value reduced by the percentage specified for 
such security in Sec.  240.15c3-1(c)(2)(vi) of this title;
    (v) Freely convertible foreign currency may be valued at an amount 
no greater than its daily marked-to-market U.S. dollar equivalent;
    (vi) Variation settlement receivable (or payable) by an account at 
the close of trading on any day shall be treated as a credit (or debit) 
to the account on that day; and
    (vii) Each other acceptable margin deposit or component of equity 
shall be valued at an amount no greater than its value under Regulation 
T.
    (2) Securities accounts. For purposes of this section, the equity in 
a securities account shall be computed in accordance with the margin 
rules applicable

to the account, subject to the following:
    (i) A security future shall have no value;
    (ii) Freely convertible foreign currency may be valued at an amount 
no greater than its daily mark-to-market U.S. dollar equivalent; and
    (iii) Variation settlement receivable (or payable) by an account at 
the close of trading on any day shall be treated as a credit (or debit) 
to the account on that day.
    (d) Satisfaction restriction. Any transaction, position or deposit 
that is used to satisfy the required margin for security futures or 
related positions under this Regulation (Subpart E, Sec. Sec.  41.42 
through 41.49), including a related position, shall be unavailable to 
satisfy the required margin for any other position or transaction or any 
other requirement.
    (e) Alternative collateral valuation for margin equity securities in 
a futures account. (1) Notwithstanding paragraph (c)(1)(iii) of this 
section, a security futures intermediary need not value a margin equity 
security at its Regulation T collateral value when determining whether 
the required margin for the security futures and related positions in a 
futures account is satisfied, provided that:
    (i) The margin equity security is valued at an amount no greater 
than the current market value of the security reduced by the lowest 
percentage level of margin required for a long position in the security 
held in a margin account under the rules of a national securities 
exchange registered pursuant to section 6(a) of the Exchange Act;
    (ii) Additional margin is required to be deposited on any day when 
the day's security futures transactions and related transactions would 
create or increase a margin deficiency in the account if the margin 
equity securities were valued at their Regulation T collateral value, 
and shall be for the amount of the margin deficiency so created or 
increased (a ``special margin requirement''); and
    (iii) Cash, securities, or other assets deposited as margin for the 
positions in an account are not permitted to be withdrawn from the 
account at any time that:
    (A) Additional cash, securities, or other assets are required to be 
deposited as margin under this section for a transaction in the account 
on the same or a previous day; or
    (B) The withdrawal, together with other transactions, deposits, and 
withdrawals on the same day, would create or increase a margin 
deficiency if the margin equity securities were valued at their 
Regulation T collateral value.
    (2) All security futures transactions and related transactions on 
any day shall be combined to determine the amount of a special margin 
requirement. Additional margin deposited to satisfy a special margin 
requirement shall be valued at an amount no greater than its Regulation 
T collateral value.
    (3) If the alternative collateral valuation method set forth in 
paragraph (e) of this section is used with respect to an account in 
which security futures or related positions are carried:
    (i) An account that is transferred from one security futures 
intermediary to another may be treated as if it had been maintained by 
the transferee from the date of its origin, if the transferee accepts, 
in good faith, a signed statement of the transferor (or, if that is not 
practicable, of the customer), that any margin call issued under this 
Regulation (Subpart E, Sec. Sec.  41.42 through 41.49) has been 
satisfied; and
    (ii) An account that is transferred from one customer to another as 
part of a transaction, not undertaken to avoid the requirements of this 
Regulation (Subpart E, Sec. Sec.  41.42 through 41.49), may be treated 
as if it had been maintained for the transferee from the date of its 
origin, if the security futures intermediary accepts in good faith and 
keeps with the transferee account a signed statement of the transferor 
describing the circumstances for the transfer.
    (f) Guarantee of accounts. No guarantee of a customer's account 
shall be given any effect for purposes of determining whether the 
required margin in an account is satisfied, except as permitted under 
applicable margin rules.
