# Regridding

> Guide to regridding in Atoti CVA Risk Capital, explaining how sensitivity input data with non-standard tenor dates is allocated to regulatory vertices using linear  interpolation to meet Basel Framework requirements

<Badge color="gray" size="lg">[SA](../tags/sa)</Badge>

## Regulatory vertices and interpolation

If tenor dates provided in the sensitivities input data do not match the regulatory vertices (for example, if the risk engine produced more granular sensitivities for the hedge instruments), the Solution allocates the sensitivities to tenors defined in \[MAR50] using linear interpolation. The resulting tenors can be displayed using this hierarchy: [\[Vertices\].\[Vertices\]](../cube/vertices.vertices).
