A negating expiration entry is made to expire 
                         points leaving the original entry intact
                         (e.g. original points + expiration points = 0).
                         When the expiration entry is made this description will
                         be placed on the entry. This is useful so the users will
                         know what happened to their point balance. In crafting
                         your message you can use the following variables. 
                         <br /> !points = The name used in branding 
                         above (also use !Points and !point)
                         <br />!operation = Original operation that granted the points 
                         <br/> !description = Original description for the point 
                         <br /> !txn_id Original transaction ID 
                         <br /> !date = Date of the original entry
