Supported sign-off adjustments - Atoti Hub

Atoti Market Risk includes five sign-off adjustment types — add-on, scaling, override, roll-over, and cube-level — available across the Sensitivities, PnL, and VaR-ES cubes.

Adjustment types

Multiple adjustment types are available out of the box in Atoti Market Risk.

Cube	Adjustment type	Description	Input value type	Base value type
Sensitivity Cube	Add-on	Time-bucket indexed (tenors, maturities, and moneyness, where applicable) add-on value. Results in a single new row per adjustment.	Double	Double
	Scaling	Time-bucket indexed (tenors, maturities, and moneyness, where applicable) scaling of the base value. Results in two rows, for the inversion of the base value and the scaled new value.	Double	Double
	Override	Time-bucket indexed (tenors, maturities, and moneyness, where applicable) override of the base value. Results in two rows, for the inversion of the base value and the new value.	Double	Double
	Roll-over	Performed for a desk, a book, or a trade. Results in inversions of all the rows matching the current as-of date, and new rows for all the matches on the previous as-of date.	Date	Double

Execution details

Functional workflow

Executing an adjustment should conform to the following steps:

Step	Details
Retrieve supported adjustments from the appropriate REST endpoint	The adjustment requests need to conform to the specification returned by the supported adjustments service, but once the requests are created, this step isn’t necessary.
Initiate the sign-off task	The status of the Sign-off process for the filters defined in the association Sign-off task is set to ‘INITIATED’.
Request adjustment.	Adjustment requests will be executed asynchronously on the Sign-off snapshot. There is no limit to the number of adjustments that can be requested for a snapshot.
Approve the sign-off task	The status of the Sign-off process for the filters defined in the association Sign-off task is set to ‘APPROVED’.
Retrieve the status of an adjustment execution	As adjustments are executed asynchronously, a service is provided for retrieving the status of a given adjustment execution. Any errors in the execution of an adjustment will result in a `FAILED` status being returned by the status service.
