# Net JTD

The **Net JTD [Long](../../../../../../../cube/drc-sec-non-ctp-net-jtd-long)/[Short](../../../../../../../cube/drc-sec-non-ctp-net-jtd-short)** measures are calculated from the **Scaled Gross JTD** according to [MAR22.29](https://www.bis.org/basel_framework/chapter/MAR/22.htm?inforce=20230101\&published=20200327#paragraph_MAR_22_20230101_22_29).

For each tranche, the Scaled Gross JTD is aggregated over all exposures to the tranche, then one of the Net JTD Long or Net JTD Short values are set to this aggregate according to whether it is positive or not.
