Just to be clear, MWD indicates that AtLRT and Ultimatum both precede the LBS filing.

ie. Within a set period of time, perhaps a week, the LBS MUST file.

AtLRT and Ultimatum both need to be from a firm position in the mind of a LBS because if you are not prepared to file, then both techniques are simply viewed as a tactic to get the WAS back.

Your choice.
