What does it mean for Mercer to finally designate unavailability?

Mercer's final definition of "unavailable" is as follows:

The final designation of American competition as unavailable usually refers to the emergency when the papers of the participating teams are cancelled or unable to participate in the mathematical modeling competition for American college students. This may be due to sudden illness or injury of team members, weather, technical failure or other unforeseen circumstances.

If a team is designated as "unavailable", it will not participate in the final grading or ranking, nor will it receive any reward.
