# Input files (reference implementation)

This section describes how the input files containing the sensitivities and mappings are used for the CSR Sec non-CTP risk class

<Tabs>
  <Tab title="Atoti FRTB">
    The sensitivities are loaded from the [Delta](./sbm-delta-sensi),
    [Vega](./sbm-vega-sensi), [Curvature](./sbm-curv-sensi),
    or [CRIF](../../../../../../input-files/crif/index) sensitivity files.
  </Tab>

  <Tab title="FRTB SA QIS">
    The sensitivities are loaded from the [Delta](./sbm-delta-sensi),
    [Vega](./sbm-vega-sensi), [Curvature](./sbm-curv-sensi),
    or [CRIF](../../../../../../input-files/crif/index) sensitivity files.

The mapping of **Sector** and **Credit Quality** to **Bucket** is loaded from the [CSR Sec non-CTP Buckets](../../../../../../configuration/csr-sec-non-ctp-buckets) file
into the into the [CSRSecNonCTPBucket](../datastore-ref-impl/csr-sec-non-ctp-buckets) store
A description of these buckets is loaded from the [CSR Sec non-CTP Bucket Descriptions](../../../../../../input-files/csr-sec-non-ctp-bucket-descriptions) file.
