Interactive Broker Model Price?

Does anyone know what the "Model Price" for an option on Interactive Brokers represents?

I am looking at CROX and the puts seem over priced and the calls seem under priced???

Thanks for any advice.

 

Have you reviewed the help files?

 

Yes, with no luck, if you find it there i would appreciate it if you would post it.

 

Grrr...
