This is part of the optional ARO module for EZLease.
Whenever you change any of the ARO System Options, all AROs in the currently open database are recalculated (since changing any of these options alters the present and future values of AROs). If a database with AROs is not open when you change the options, you should force a recalculation of its AROs by opening the database and clicking this Recalculate button. Otherwise, report results may be unreliable.
