A hedging misalignment parameter, which is designed to limit the extent to which indirect hedges can reduce capital requirements given that they will not fully offset movements in a counterparty’s credit spread.

Notation
$\sum_{c} HMA$
Formula
$$\sum_{c} HMA=\sum_{c} \sum_{h \in c} \left(1- r_{hc}^2 \right) \cdot \left( RW_{h} \cdot M_h \cdot B_{h} \cdot DF_h \right)^2$$
