I Purchased and Sell a Company's .NET Domain—Looking for Advice

Hello! I recently bought a .net domain for a company that uses the .com version of the same name. It's a fairly big company—not huge, but not small either. I'm trying to sell the domain for around $5,000 on Afternic, but I'm worried they might file a UDRP against me since the domain is literally their company name with a .net extension. Do you have any advice? I'm concerned, but I also need some cash for food. Thanks!

Note: I actually worked for them as well
