The Revenue-Based Attrition Clause helps event planners manage financial risks by linking attrition penalties to actual room revenue rather than just room nights. This approach ensures that planners are only penalized for significant shortfalls in revenue, taking into account higher-paying rooms like suites and upgrades. It provides a fairer, more transparent framework for both parties, offering clear guidelines on how shortfalls are calculated and protecting planners with occupancy and resale provisions.
