The “k” value is used in the Day Ahead – Intraday Market collateral (DAM-IM) calculations and it represents the last “k” days in which the commercial transactions in these two markets are different than zero in last 30 days. Within the scope of Collateral Calculation Procedure, for public holidays longer than two days, the “k” number is 1 (one) more than the number of days on the holiday.

In cases where the “k” value is greater than three, for the total collateral calculation the following rules are applied:

75% of the amount calculated over the “k” number is used on workdays before the holiday

100% of the amount calculated over the “k” number is used on workdays following the holiday

Due to Feast of Ramadan Holiday, for the DAM-IM collateral calculation to be made on 10 May, 11 May and 17 of May, the number of “k” days is 6 (six).
