# Default risk charge

> The Default Risk Charge dimension in FRTBCombinedCube, covering hierarchies for DRC non-Sec, Sec CTP, and Sec non-CTP exposures, including buckets, ratings, seniority, attachment points, and LGD type

The **Default Risk Charge** dimension contains the following hierarchies:
