The reason it is an asset is because they have an agreement with the government to buy the property for $100 at the end of the lease. I expect them to be able to get those account receivables because it is from legit business in the movie industry and it is rare for a default in that type of business in my opinion.
I will look again but I am pretty sure the account receivables is NOT the credit line lol
I have given you the best info I can, but you really have to contact the company or IR and ask them for your answers. Don't go on what I say, make your own decisions.
