The "Historical amounts - Restore Defaults" menu choice allows you to delete values in the historical average wage series, benefit increases, and wage bases that have been entered via the Historical amounts - update menu item, and/or modified via the Historical amounts - modify menu item. This selection is not available if you have not entered any values via those menu items. The form has an OK button to continue with the restoration of defaults, or a Cancel button to return without restoring the defaults.
