# SES calculations

The following measures walk through the SES calculation and can be found in the bookmark: Basel Framework → IMA → NMRF.

The SES calculations begin with the "Capital requirements for each non-modellable risk-factor" from [MAR 33.16](https://www.bis.org/basel_framework/chapter/MAR/33.htm?inforce=20230101\&published=20200327#paragraph_MAR_33_20230101_33_16).  This is expected to be a single value in the input, however, if a vector is provided, the Solution will take the 97.5% ES.

* The [ES (SES)](../../../../cube/es-ses-ima) measure is the capital requirement for the NMRFs filtered on idiosyncratic = N.
  The **Risk Factor** level must be present in queries for this measure.

* The [ES (ISES)](../../../../cube/es-ises-ima) measure is the capital requirement for the NMRFs filtered on idiosyncratic = Y.
  The **Risk Factor** level must be present in queries for this measure.

* The [SES](../../../../cube/ses-ima) measure uses the **ES (SES)** and **ES (ISES)** measures to calculate *SES* in [MAR 33.17](https://www.bis.org/basel_framework/chapter/MAR/33.htm?inforce=20230101\&published=20200327#paragraph_MAR_33_20230101_33_17).
  The value of ρ comes from the `ima.rho.ses` parameter and defaults to 0.6.
