LIV Golf told employees in the U.S and U.K. Wednesday morning that it is likely facing layoffs, according to someone familiar with the details who was not authorized to speak publicly.

The upstart tour is filing a Worker Adjustment and Retraining Notification (WARN) Act notice—a legal requirement and not a definitive workforce reduction; the U.K. also has layoff notification requirements. The WARN Act requires most businesses with more than 100 employees to provide 60 days’ advance notice of potential mass layoffs or plant closings.

This marks the latest challenge for the upstart golf tour since Saudi Arabia’s Public Investment Fund (PIF) pulled back on its financial support.

“There are no changes to LIV Golf’s current workforce, operations, or schedule at this time,” a spokesperson for LIV Golf said in a statement. “As our process to identify strategic investors moves forward in a positive direction, and as part of responsible planning for a range of possible outcomes, we have notified employees in the United States and United Kingdom of potential future actions related to the League’s corporate workforce. This step is being taken in accordance with legal obligations in each jurisdiction. We deeply appreciate our employees’ continued dedication as we work toward a strong and sustainable future for the League.”
