Negative interest posting in inhouse cash

hi ,

As banks now starts to have negative interest rates on deposits in banks we need to be able to calculate the same terms and conditions on IHC accounts.

We have made the attached configurations.

Now please advise which interest condition would be used for the following:

Negative Credit Interest

Negative Credit Interest adjustment

Negative Credit Interest adjustment

as all 3 may appear on a month end statement

Regards
