1. Competent authorities shall determine a baseline figure for the spot month position limit in an agricultural commodity derivative or a critical or significant commodity derivative by calculating 25 % of the deliverable supply for that commodity derivative. Where the deliverable supply is substantially higher than the total open interest, competent authorities shall determine the baseline figure for the spot month limit by calculating 25 % of the open interest in that commodity derivative.

That baseline figure shall be specified in lots.

2. Where a competent authority establishes different position limits for different times within the spot month period, those position limits shall decrease on an incremental basis towards the maturity of the commodity derivative and shall take into account the position management arrangements of the trading venue.

3. By way of derogation from paragraph 1, competent authorities shall determine the baseline figure for the spot month position limit for any commodity derivative with an underlying that qualifies as food intended for human consumption with a total combined open interest in spot month and other months' contracts exceeding 50 000 lots over a consecutive 3-month period by calculating 20 % of the deliverable supply in that commodity derivative. Where deliverable supply is substantially higher than total open interest, competent authorities shall determine the baseline figure for the spot month limit for such a commodity derivative by calculating 20 % of the open interest in that commodity derivative.
