Please note: All events at GMU are required to carry insurance and provide George Mason with a Certificate of Insurance that names the University as “Additionally Insured” (Or the Certificate Holder). 

The insurance requirements are as follows:

  • Commercial General Liability in an amount no less than $1M per occurrence with a $2M aggregate
  • If minors are present, Sexual Abuse and Molestation in the amount of no less than $1M with a $2M aggregate
  • If you will be driving people around on campus for the event, Commercial Automobile Liability in the amount not less than $1M per occurance
  • Workers Compensation in an amount not less than that prescribed by statutory limits
  • AND an Umbrella/Excess policy in an amount not less than $1M to apply OVER and ABOVE the above insurances.

At all times during this Agreement Client shall maintain the following insurance coverage:

  • Commercial General Liability in an amount not less than $1,000,000 per occurrence with a $2,000,000 aggregate;

We realize, many of our clients do not have formal event insurance with their companies.  In order to assist we have partnered with TULIP (SPECIAL EVENT INSURANCE).  You can visit this site to get an insurance quote based on your event. http://risk.gmu.edu/insurance/tulip-special-event-insurance/

We encourage all clients, to find out the costs of the insurance prior to going to contract.  Once a contract is signed, the insurance is due within 30 business days, and no later than 30 business days of the event. Failure to provide the insurance, is a breach of the contract – thus canceling the event. If this happens, no deposits are refundable.
