B is the number of such securities which he was obliged to receive at that time as a result of the earlier exercise of other options by or against him, and C is the number of such securities which he held at that time as a hedge against the likelihood of his having to deliver such securities on a future exercise of other options which he had bought or sold;

e if, following a purchase of such securities by the member in the circumstances referred to in paragraph (iv) of sub-paragraph (b), the number of securities of that kind held by him exceeds, for a period of six consecutive days, the sum of— i the appropriate limit, as calculated from day to day, in respect of securities of that kind which are required as a hedge against the likelihood of his having to deliver such securities on a future exercise of other options which he has bought or sold, and ii the number of securities of that kind required to meet his obligation to deliver securities resulting from the exercise of other options by or against him, the amount of the excess is sold by him prior to the expiry of the day following the end of that period. 4 For the purposes of sub-paragraphs (c)(iii), (d) and (e) of paragraph (3), “the appropriate limit” means— a as regards a member who is an options market maker in relation to those securities at the time of the agreement referred to in the definition of A in sub- paragraph (c)(iii) of paragraph (3) or, as the case may be, during the period specified in sub-paragraph (d) or (e) of that paragraph, the Max limit, and b as regards a member who is an options principal trader in relation to those securities at the time or, as the case may be, during the period referred to in sub- paragraph (a) of this paragraph, the Deltaplus limit or the Max limit, whichever is the less. Meanings of the Max limit and the Deltaplus limit 5 1 For the purposes of paragraphs (3) and (4) of regulation 4, “the Max limit” means, in relation to options entered into by a member who is an options market maker to buy or sell equity securities of a particular kind, the maximum number of such securities which is found by— a making the following calculation in respect of each relevant expiry month and each designated account— D - E where— D is the number of securities which he is likely to deliver, and E is the number of securities which he is likely to receive, on the exercise of options expiring within that month, on the assumption that— the market price of the securities is at a figure which having regard to paragraphs (ii) and (iii) would produce the maximum figure resulting from that calculation, such options as give the holder the right to buy such securities at a price above that market price, or to sell such securities at a price below that market price, are not exercised, and such options as give the holder the right to buy such securities at a price equal to or below that market price, or to sell such securities at a price equal to or above that market price, are exercised; b where the amount calculated by reference to sub-paragraph (a) is a negative amount, treating that amount as zero; and c aggregating the amounts so calculated in respect of all relevant expiry months and designated accounts. 2 For the purposes of paragraphs (3) and (4) of regulation 4, “the Deltaplus limit” means, in relation to options entered into by a member who is an options principal trader to buy or sell equity securities of a particular kind, the maximum number of such securities which is found by— a subject to sub-paragraph (c), making the following calculation in respect of each relevant expiry month and each designated account— F - G where— F is the number of such securities which he is likely to deliver on the exercise of options expiring within that month, calculated by multiplying the most recently published Delta number by the number of securities in respect of each option which would be transferred if that option were exercised, and G is the number of securities which, adopting the same method of calculation, he is likely to receive, on the exercise of such options; b increasing the amount calculated in sub-paragraph (a) by 20 per cent. of the sum of the number of such securities which he would be obliged to deliver and the number he would be obliged to receive, if those options were all exercised;\ c where at the time of calculation such options would expire, unless previously exercised, within a period of four weeks, making the calculation specified in paragraph (1)(a) of this regulation in respect of those options for the relevant expiry month instead of the calculations referred to in sub-paragraphs (a) and (b) of this paragraph; d where the amount calculated by reference to sub-paragraphs (a) and (b) or the amount calculated by reference to sub-paragraph (c) is a negative amount, treating that amount as zero; and e aggregating the amounts so calculated in respect of all relevant expiry months and designated accounts.
